CONNECTOR
Thls application is related to the field of electrical connectors. In particular, this appli-cation is related to panel mount ~useholders.
BACKGROUND OF THE INYENTION
Numerous kinds of fuseholders~ particularly panel mount ~useholders, are known. Such fuse-holders include an insulating body of a generally cylindrical or tubular shape for holding a fuse, a cap member for retaining the ~use, and contact members ror establlshing electrical contact with the end caps or ~errules o~ a fuse member within the fuseholder. Typlcally, the cap includes a generally tubular portion or fuse clip ~or making electrical contact with one ferrule or end cap of the ~use member, and for connectlng the cap to the body. Thls tubular member ls provided with exter-nal screw threads, cooperatlng with internal screw threads on a conductive socket member within the body, and connected to a 6ultable terminal, so that connectlons to both ends of the fuse member can be made on a single side o~ the panel. Such metalllc tubular portlons are also provlded with bent-out tab portions, which cooperate with L-s~
shaped slots or the like to establlsh a bayonet-lock type connection between the cap and the body.
Since the use o~ bayonet-lock type fuseholders and æcrew-type fuseholders is a matter of the user's pre~erence~ lt has heretofore been necessary to manufacture two different and incompatible ~use-holders, with one or two minor compatible pieces, such as one terminal post and a retaining nut which retains a panel mount fuseholder to a panel~
The nonconductive portion o~ the cap may be siml-lar, but, since the di~ering tubular portions must be inserted at initial fabrication of the cap assembly, two entirely dif~erent cap assemblies must be produced.
The bayonet and screw-type connections conven-tionally used are metal-to-metal connections, whlch are inherently smooth, and with a low coe~
~icient of frlction. When no ~use is inserted, the fuse caps are apt to loosen and become separated from the remainder o~ the fuseholder.
This is particularly true of the bayonet-lock type, since the force provided by a fuse pressing against a resilient spring ln either the cap or the body is required to keep the mating portlons of the bayonet lock correctly positioned.
Also, bayonet fuseholders of known types are des~gned in such a way that accidental depression of the cap may result in a momentary open circuit.
In some applications, such as sequentially operating equlpment including numerically-controlled machine tools, such an accidental depresslon may result ln damaged workpieces and a need to resta~t ~ task ~rom the beglnning.
The lnstant invention overcomes these and other disadvantages o~ the prior art.
Accordlnq to the present inventlon -there is provided a fuseholder which has a body portion which is adapted to con-tain at least a portion of a generally cylindrical fuse mernber, the fuse member having a body section and first a.nd second end cap portions at opposite ends thereof. The body por-tion of the fuse~
holder includes a-t a first end thereof a contact rnember adapted to contact the first end cap por-tion of the fuse member, the first contact member extending to the exterior of the first end of the body por$ion and including a connec~ion portion adapted to receive an electrical connection thereto. A cap por-tion is provided for retaining the fuse member in the fuseholder, the cap portion including means for retaining the second end cap portion of the fuseholder and resilient means adapted to contact the second end cap po:rtion to urge the fuse member -towards the con~act member when the cap portion is joined to the body portion. The means for retaining the second end cap portion is a tubular member protruding from an end thereof and adapted to be inserted into the body portion. r~he body portion includes a second contact portion ~dapted to frictionally receive the tubular member and to establish electrical connection thereto, the second contact portion including a generally ring-shaped portion adapted ~o receive the tubular portion and a second connection po~tion extending to the exterior of the body portion and adapted to receive an electrical connect.ion thereto. The cap member has a joining member for ~oining the cap portion to the body por~ion, the joining portion being freely rotatably mounted to the cap member. The body portion includes means adapted to cooperate with the ~oining member for joining the cap portion to the body portion and establishing electrical current path from the second end cap portion through the tubular member and the resilient means to the generally ring-shaped portion and the second connection portion.
A specific embodiment of the invention provides~ a panel mount fuseholder with nonconductive elements for retaining the cap to the body, and conductive elements only for establishing electrical connection. It is an advantage of this arrangement that the resilience and high coefficient of friction of nonconduc-tive materials such as plastics may be used to fasten the cap and body of the fuseholder. It is a feature of this arrangement that lm/
: -3-~ ,. .

the cap and the body of the fuseholcler are more firmly retained togeth~r when a fuse is not installed in the fuseholder.
It is an object o:E the invention to produce a fuse-holder which includes a maximum number of common components, minimizing the number of production steps, the number of tools and dies necessary to make fuseholders. It is an advantage of the invention that a less expensive and more dependable fuseholder can be produced. It is a feature of the invention that a common cap me~ber may be provided with a freely rotatably mounted joining member, in either bayonet-lock or screw thread type, for example, for cooperating with matching provi.sions on an extension portion of the fuseholder body, so that a single mold may be used to form the ~useholder body, with interchangeable mold portions fox forming angled bayonet-lock grooves or screw threads on the extension portion of the body of the fuseholder.
In a speci.~ic embodiment of the invention, pressure applied to the cap will not result in interrupted lm/
~3A-;~ , 3~
electrical continuity. It is a feature of this invention that the means for retaining the cap ls separate from the means for establishing'electri-cal contact~ It is an advantage of the lnvention that such a fuseholder may be installed ln a loca-tion that is sub~ect to frequent accidental con-tact.
These and other ob~ects, features and advan-tages of the invention will become apparent ~rom the description which followsO

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring lnitially to FIG. 1, there is shown a fuseholcler 10, in perspective, illustrating the ~5~
e~ternal appearance of either of the two preferred embodiments shown in the succeeding figures.
Also, since the external appearance, as well as numerous component parts are identical between the two preferred embodiments, ldent~cal reference numerals for interchangeable components will be used.
Fuseholder 10 includes a body portion 12 shown as including an enlarged portlon 14 and a flange portion 160 ~lange portion 16 is shown as a diamond-shaped flange with mounting holes 18 pro-vided for the passage of fasteners such as screws or rivete to mount fuseholder 10 to a mounting surface or panel. Body portion 12 has a first end 209 and includes provisions for making electrlcal connectlon to a fuse in fuseholder 10 protruding from body portion 12. A first connection portion 22 and a second connection portion 24 are electri-cally connected to opposing end caps or ferrules of a fuse member, as will be explalned more fully below. Also, first end 20 of body portion 12 is, in the preferred embodiment, of a square or rec-tangular cross section, although any desired cross sectlon, such as a cylindrical section may be used, if desired.
Fuseholder 10 also includes a cap portion 26 and a ~oining portion 28 for Joining cap 26 and body 123 which is freely rotatably affixed to cap portion 12 by means of ~ plurallty of mounting fingers 30 whlch snap into a groove as best shown in FIGS. 5 and 7.
Referring now to FIG~ 2, a fuseholder lOa which has a bayonet-type interlock between the cap and body portions 26 and 12. As shown, body por~
s~
tion 12 lncludes an extension portion 32, which includes provisions for the bayonet interlock feature Or fuseholder lOa.
At this point, it should be noted that the design of tools and dies necessary to manufacture such a fuseholder will be an obvious and routine ma~ter to one skilled ln the molding and manuracturing arts, and it will also be obvious that suitable molds can be easily made where the portion that molds extension por-tion 32 is removable, so that a mold portion for providing a screw interlock feature may be eas~ly substituted. As shown, extension portion 32 surrounds entrance aperture 34, and defines~ on its radial peripheral surface, a plurality Or angled or L-shaped slots or grooves 38 appropriate for the ~emale portion of a bayonet interlock.
~he interior surface of extension portion 32 also defines a first recess and a pair of second recesses 42. Recesses 40 and 42 are used to guide and support a second conductive contact portion of which second connection portion 24 is an integral part. Also shown in FIG. 2 is a fuse member 44 having a body portion 46, a first end cap or ferrule 48 and a second end cap or ferrule 50. As will be decribed in greater detail below, cap por-tion 26 includes a tubular 52 forming a fuse clip for retaining end cap 50 of fuse 44 to facilitate the insertion and removal of fuses such as fuse 44 into a body portion 12.
Referring now to FIGS. 3 and 4, the fuseholder lOa shown in FIG. 2 is shown in an exploded view, with FIG. 3 being an exploded view of body portion 12~ and F:[G. Il being an exploded view o~ cap por-a tion 26 and ~oining portion 28a. A first conduc-tive contact portion 54 includes first connection portion 22 and a fuse member contacting portion 56, and a retalning flange 580 First connecti-on portion 22 ls adapted to receive an electrical connection, such as by a screw, screw and nut, or screw and clamp assembly passed through hole 60, a wire soldered through hole 60, or, preferably, a conventional quick-connect female connector slipped over connection portion 22. Portion 56 provldes a means for conveniently ad~usting a fuseholder according to the invention to accept fuse members such as fuse member 44 o~ differing length. To adapt such a fuseholder to a shorter fuse, portion 56 is merely made longer to compen sate for the shorter length of ~use within body portion 12 As is better shown in FIG~ 5, first conductive contact portion 54 is inserted into body 12 while it is still hot and plastic after molding, retaining flange 58 forming a retaining groove in an interior surface of body portion 12c A second conductive contact portion 62~ of which second connection portion 24 -is an integral part, is inserted later. As shown, second conductive contact portion 62 includes a generally ring-shaped portion 64l provided with a diverging entrance section 66, and interrupted to form a gap 68. Portion 64 is also provided with locating tabs 70 which cooperate with grooves 44. At assembly, second conductlve contact portion ls inserted in body 12 such that second connection portlon 24 engages first recess 40, and tabs 70 in gauge second recesses 42, and second connection portion 24 is pushed through aperture 720 When second conductive contact portion 62 is fully seated within body portion 12, tabs 74 of second connection portlon 24 protruding through aperture 72 are bent to prevent second conductlve contact portion 64 from being wlthdrawn. As with first connection portion 22, second connection portion 24 is also adapted to receive an electrical con-nection, such as by a screw, screw and nut or screw and clamp assembly passed through hole 76, a wire soldered through hole 76, or a conventional female quick-connector slipped over second connec-tlon portion 24~ The diameter o~ inner surface 78 Or generally ring~shaped portion 64 is chosen to closely receive tubular member 52, rOr establishing electrical contact between second connector portion 24 and tubular member 52.
Re~erring now to FIG. 4, there are shown the individual components o~ a cap assembly in accor~
dance with the invention, in an exploded view.
Z0 This figure also illustrates the method of assembly of a cap assembly according to the inven-tion. A resilient means for urging a fuse against ~irst conductive contact portion 54 when the fuse-holder is assembled is shown as a conical helical

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring lnitially to FIG. 1, there is shown a fuseholcler 10, in perspective, illustrating the ~5~
e~ternal appearance of either of the two preferred embodiments shown in the succeeding figures.
Also, since the external appearance, as well as numerous component parts are identical between the two preferred embodiments, ldent~cal reference numerals for interchangeable components will be used.
Fuseholder 10 includes a body portion 12 shown as including an enlarged portlon 14 and a flange portion 160 ~lange portion 16 is shown as a diamond-shaped flange with mounting holes 18 pro-vided for the passage of fasteners such as screws or rivete to mount fuseholder 10 to a mounting surface or panel. Body portion 12 has a first end 209 and includes provisions for making electrlcal connectlon to a fuse in fuseholder 10 protruding from body portion 12. A first connection portion 22 and a second connection portion 24 are electri-cally connected to opposing end caps or ferrules of a fuse member, as will be explalned more fully below. Also, first end 20 of body portion 12 is, in the preferred embodiment, of a square or rec-tangular cross section, although any desired cross sectlon, such as a cylindrical section may be used, if desired.
Fuseholder 10 also includes a cap portion 26 and a ~oining portion 28 for Joining cap 26 and body 123 which is freely rotatably affixed to cap portion 12 by means of ~ plurallty of mounting fingers 30 whlch snap into a groove as best shown in FIGS. 5 and 7.
Referring now to FIG~ 2, a fuseholder lOa which has a bayonet-type interlock between the cap and body portions 26 and 12. As shown, body por~
s~
tion 12 lncludes an extension portion 32, which includes provisions for the bayonet interlock feature Or fuseholder lOa.
At this point, it should be noted that the design of tools and dies necessary to manufacture such a fuseholder will be an obvious and routine ma~ter to one skilled ln the molding and manuracturing arts, and it will also be obvious that suitable molds can be easily made where the portion that molds extension por-tion 32 is removable, so that a mold portion for providing a screw interlock feature may be eas~ly substituted. As shown, extension portion 32 surrounds entrance aperture 34, and defines~ on its radial peripheral surface, a plurality Or angled or L-shaped slots or grooves 38 appropriate for the ~emale portion of a bayonet interlock.
~he interior surface of extension portion 32 also defines a first recess and a pair of second recesses 42. Recesses 40 and 42 are used to guide and support a second conductive contact portion of which second connection portion 24 is an integral part. Also shown in FIG. 2 is a fuse member 44 having a body portion 46, a first end cap or ferrule 48 and a second end cap or ferrule 50. As will be decribed in greater detail below, cap por-tion 26 includes a tubular 52 forming a fuse clip for retaining end cap 50 of fuse 44 to facilitate the insertion and removal of fuses such as fuse 44 into a body portion 12.
Referring now to FIGS. 3 and 4, the fuseholder lOa shown in FIG. 2 is shown in an exploded view, with FIG. 3 being an exploded view of body portion 12~ and F:[G. Il being an exploded view o~ cap por-a tion 26 and ~oining portion 28a. A first conduc-tive contact portion 54 includes first connection portion 22 and a fuse member contacting portion 56, and a retalning flange 580 First connecti-on portion 22 ls adapted to receive an electrical connection, such as by a screw, screw and nut, or screw and clamp assembly passed through hole 60, a wire soldered through hole 60, or, preferably, a conventional quick-connect female connector slipped over connection portion 22. Portion 56 provldes a means for conveniently ad~usting a fuseholder according to the invention to accept fuse members such as fuse member 44 o~ differing length. To adapt such a fuseholder to a shorter fuse, portion 56 is merely made longer to compen sate for the shorter length of ~use within body portion 12 As is better shown in FIG~ 5, first conductive contact portion 54 is inserted into body 12 while it is still hot and plastic after molding, retaining flange 58 forming a retaining groove in an interior surface of body portion 12c A second conductive contact portion 62~ of which second connection portion 24 -is an integral part, is inserted later. As shown, second conductive contact portion 62 includes a generally ring-shaped portion 64l provided with a diverging entrance section 66, and interrupted to form a gap 68. Portion 64 is also provided with locating tabs 70 which cooperate with grooves 44. At assembly, second conductlve contact portion ls inserted in body 12 such that second connection portlon 24 engages first recess 40, and tabs 70 in gauge second recesses 42, and second connection portion 24 is pushed through aperture 720 When second conductive contact portion 62 is fully seated within body portion 12, tabs 74 of second connection portlon 24 protruding through aperture 72 are bent to prevent second conductlve contact portion 64 from being wlthdrawn. As with first connection portion 22, second connection portion 24 is also adapted to receive an electrical con-nection, such as by a screw, screw and nut or screw and clamp assembly passed through hole 76, a wire soldered through hole 76, or a conventional female quick-connector slipped over second connec-tlon portion 24~ The diameter o~ inner surface 78 Or generally ring~shaped portion 64 is chosen to closely receive tubular member 52, rOr establishing electrical contact between second connector portion 24 and tubular member 52.
Re~erring now to FIG. 4, there are shown the individual components o~ a cap assembly in accor~
dance with the invention, in an exploded view.
Z0 This figure also illustrates the method of assembly of a cap assembly according to the inven-tion. A resilient means for urging a fuse against ~irst conductive contact portion 54 when the fuse-holder is assembled is shown as a conical helical
2~ spring 80 having an outermost coil 82, As is better shown in FIGS. 5 and 7, spring 80 is inserted into an axial bore 84 in cap portion 26, preferably at a tlme when cap portion 26 is still warm and somewhat plastlc after molding~ and retained by contact of edge 86 of tubular member 52 against outermost coil 82. Tubular member 52 is preferably inserted into axial bore 84 imme-diately followin~ the insertion o~ sprlng 80.
Tubular member 52 is provided with an indented portlon 88, deflned by a generally U-shaped slit in tubular member 52. This indented portion 88 serves to frictionally retain an end cap or ferrule of a fuse, such as end cap 5O of fuse~
me~ber 44, to facilitate its lnsertlon and removal from the fuseholder.
In manufacturing the il:Lustrated embodiment of the invention, ~oining port.Lon 28a is then freely rotatably mounted on cap portion 26 by positioning Joining member 28a so that :Latchin~ portlons 90 of mounting fingers 30 engage groove 92 defined by surface 94 of cap portlon 26. As illustrated, Joining portion 28a has a knurled or serrated area shown as area 96, to facilitate its manual rotation with respect to cap portion 26.
At this polnt, it should be speci.fically noted that certain features of the disclosed fuseholder are usable in any type of electrical connector.
In particular, the freely rotatable mounting of a ~oining portion for fastening a cap portion ln place ~y providing the ~oining portion with a plurality of resilient mounting fingers such as ~ingers 30 and latching portions such as portions 9O for cooperating with a groove such as groove 92 in a cap such QS cap portion 26. Obviously, in such an application, spring 8~ and tubular member 52 may be omitted, and an axial bore such as axial bore 84 could be made to extend throughout the body of a cap member such as cap member 26, which would be an obvious modification of this feature o~ the invention ~or use, with other conventional components, as a connector in itself. In other words, this disclosed feature of the invention is usable with any .first body defined by a surface of
Tubular member 52 is provided with an indented portlon 88, deflned by a generally U-shaped slit in tubular member 52. This indented portion 88 serves to frictionally retain an end cap or ferrule of a fuse, such as end cap 5O of fuse~
me~ber 44, to facilitate its lnsertlon and removal from the fuseholder.
In manufacturing the il:Lustrated embodiment of the invention, ~oining port.Lon 28a is then freely rotatably mounted on cap portion 26 by positioning Joining member 28a so that :Latchin~ portlons 90 of mounting fingers 30 engage groove 92 defined by surface 94 of cap portlon 26. As illustrated, Joining portion 28a has a knurled or serrated area shown as area 96, to facilitate its manual rotation with respect to cap portion 26.
At this polnt, it should be speci.fically noted that certain features of the disclosed fuseholder are usable in any type of electrical connector.
In particular, the freely rotatable mounting of a ~oining portion for fastening a cap portion ln place ~y providing the ~oining portion with a plurality of resilient mounting fingers such as ~ingers 30 and latching portions such as portions 9O for cooperating with a groove such as groove 92 in a cap such QS cap portion 26. Obviously, in such an application, spring 8~ and tubular member 52 may be omitted, and an axial bore such as axial bore 84 could be made to extend throughout the body of a cap member such as cap member 26, which would be an obvious modification of this feature o~ the invention ~or use, with other conventional components, as a connector in itself. In other words, this disclosed feature of the invention is usable with any .first body defined by a surface of
3~
-10~
revolution, such as cap member 26, including an axial bore extending at least partly through the ~irst body, such as axial bore 84, with an annular-body such as ~oinlng portion 28a adapted to ~oln the first body upon whi.ch it is mounted to a second body, which ls freely rotatably mounted to the first body by means Or a plurality of resil ient mounting fingers each including a generally-perpendicular latching portlon, such as fingers 30 and portions 90, which cooperate with an annular groove such as groove 92 ln an outer surface such as surface 94 of a first body such as cap member 26.
Referring now to FIG. 59 a detalled sectional view of the first embodiment of the invention, lt can be seen that flrst conductive contact portion 54 is inserted through entrance aperture 34 to flrst end 20 of body portion 12 while it is still somewhat plastic after molding, so that ~irst con-nection portion 22 passes through aperture 100,and so that retaining flange 58 forms a retaining groove 102 ad~acent first end 20. Fuseholder lOa is shown installed through an aperture 104 in a panel 106, and retained either by fasteners passing through mounting holes 18, or, lf a suitable shape for flange 16 for mounting holes 18 is not desired~ by a retaining means shown as a retaining washer 108 similar in shape to an internal-tooth lock washer applied to enlarged portion 14 ad~acent panel 106~ An 0-ring 110 is shown placed ln a groove 112 in flange portion 16 ad~acent panel 106, for forn1ing a waterproof seal between ~lange portlon 16 and panel 106.
Also, as shown in detail, edge 86 o~ tubular 5~1~
member 52 has a tapered area 114 for insertion within inner surface 78 of generally rlng-shaped portion 64, to make electrical connection between tubular member 52 and second connector portion 24 Cap portion 26, with tubular member 52, is retained to and fastened to body portion 12 by a bayonet-lock fastening formed by inwardly-directed protrusions 116 from interlor surface 118, cooperating with angled slots formed in exterlor surface 122 of extension portion 32, forming a bayonet lock between cap 26 and body portion 12u As also can be seen, ~oining portion 28a is freely rotatably mounted to cap 26 by means of latching portions 90 of mounting fingers 30 engaging groove 15 92. An O~ring 124, for forming a waterproof seal between cap 26 and extension portion 32 of body portlon 12 is shown interposed between end surface 126 of extension portion 32 and stepped portion 128 between surface 94 and a surface 130 of cap 20 portion 26. As shown, surface 130 defines the outer diameter of a pilot portion 132 of cap por-tion 26 which is recelved wlthin an inner surface 134 of extension portion 32.
FIG. 6 i8 a sectional view taken along line 25 6-6 in FIG. 5, and shows tubular member 52 received within generally rlng-shaped portion 64, with locating tabs 70 disposed in second recesses 42, and second connection portion 24 disposed in first recess 40.
FIG. 7 shows a fuseholder lOb, which is slml-lar ln all respects other than the configuration of a Joining portion 28b and an extension portion 32a, so that otherwise-identical manufacturing and assembly procedures apply. Identical reference 3~
numerals are used for identical parts. As can be seen, the only significant difference between FIGo 5 and FIG~ 7 is that a screw-type interlock rather than a bayonet-type :lnterlock is provided between cap portion 26 and body portion 12. As : shown in FIG. 7, ~oini:ng portlon 28b includes a screw thread 140 ~ormed or defined in interior sur~ace 113 of ~olning member 28b, which cooper-ates wlth a screw thread 142 formed in exterior surface 122. Screw threads 140 and 142 are o~
identical pitch dlameters and lead, and are pre-ferably multiple-entry screw threads~ so that less than a full turn of Joining portion 28b is necessary to engage threads 140 and 142.
Thus, in elther the first or second dlsclosed embodirnents of the invention, a connection ls made to a fuse such as fuse 44, current flowing, for example, from first connection portion 22 to fuse member contacting portion 56, to first end cap 48, through fuse 44 to second end cap 50, and then primarily through conical helical spring 80 to tubular member 52. Tubular member 52 is ln electrical contact with generally ring~shaped por-tion 64, so that current flows into generally ring-shaped portion 64, and then to second connec-tion portion 24, completlng an electrical circuit between connection portions 22 and 24.
In addition to the multiple uses Or the novel features of cap 26 and ~oining portions 28a or 28b, it will be apparent to one skilled in the art that numerous modlfications and variations Or the disclosed embodiments of the invention may be easily made, without departing from the spirit and scope of the invention.
