Embodiment
The present invention is to form crooked adjustable connector (this paper is also referred to as " can regulate accessory " or " connector ") when cable is advanced for armouring or other type cable.Generally speaking, armoured cable be clad and comprise one or more insulated electric conductor.Preferably, armoured cable is aluminium armoured cable flexible, interlocking, has inner PVC overcoat and outside PVC overcoat is arranged in the armouring outside at insulated electric conductor.This cable is referred to herein as " technology cable (teckcable) ".But the present invention is not limited to for the armoured cable of technology cable or other type and can be used for any cable.As used herein term " armoured cable " meaning is metal (for example steel, aluminium or brass) or nonmetal (plastics) cable duct or the cable with flexibility, fold building, and it can have or not have the interlocking helical member, overcoat can be arranged or not have overcoat or lining be arranged or do not have lining (for example PVC overcoat or lining).
The present invention relates to regulate accessory or be used at the crooked connector of cable.Two or more parts that connector has porose (being also referred to as axial hole), these holes pass these parts basically as the crow flies.This connector can directly insert in each straight hole of each parts of accessory cable easily and needn't cable be bent to consistent with the shape of accessory as the situation of elbow fittings.This does not need ground consuming time and usually difficult ground prebuckling cable and forces wire harness to pass through 90 degree elbows.
In preferred construction, axial alignment and the formation of forming two or more parts of connector can be led directly to connector and unbending hole basically.Should be convenient to insert cable by " leading directly to " structure.Needs carry out that cable is advanced and bending after, rotatable (or rotation) connector component (being body and hub) is to form desired angle and in place with anchor clamps and coupling nut locking then.Before connector locked onto fixing position or orientation, the angle that is formed by connector can change to 90 degree from 0.In some application scenario, it is more convenient that the user may find before inserting cable connector to be adjusted to special angle.In other application scenario, the user can select not exclusively to tighten coupling nut makes the parts of cable and connector not be locked in fixed orientation and free to rotate.
When forming bending in cable, the bending of conductor only takes place in the position of accessory inboard.This is the remarkable improvement to the prior art elbow, the angle of bend that whole cable is advanced and needed prebuckling and be forced to pass elbow in the prior art.Straight-through being configured in alignment and concentric body and the hub of regulating each parts of accessory of the present invention provides opening.The coupling flange that is obliquely installed of the flange end that is obliquely installed of body and hub respectively has elliptical openings, and this opening has main shaft (being the ultimate range between the opening opposite side) and secondary axis (being the minimum range between the opening opposite side).When body and hub rotated to be formed for the different angles of connector, the minimal openings on the connector equaled the secondary axis (littler that) of body or hub at least.
Adjustable connector comprises body and the hub that rotatably is linked together, make each member between primary importance and the second place, to rotate with respect to another, body vertically extends to provide straight line to be connected (i.e. 0 degree or 180 degree) with hub alignedly in primary importance, and the longitudinal axis of body and hub becomes 90 degree ground extensions to be connected to form 90 degree with respect to another axis in the second place.Anchor clamps are installed on the coupling flange of the flange end of body and hub with the position of fixed body with respect to hub.Can also connect body and hub with any angle between first and second positions by body and hub being rotated to desired orientation, and tighten coupling nut against anchor clamps then body and hub are locked in fixing position.
The body part of adjustable connector has longitudinal axis and comprises the hole of extending between flange end, cable link and this two ends.Preferably, the opening in the flange end greater than the opening in the link so that be connected to coupling flange on the hub, such as described in more detail below.Flange end has flat surfaces basically, and this flat surfaces extends and is obliquely installed with respect to the longitudinal axis of body around the opening of body.Preferably, the surface of flange end arranges to about 60 degree angles with about 30, and best with about miter angle setting.The cable link can have screw thread can have the level and smooth end that uses compression fitting to connect body is connected to accessory or shell or its.
Hub comprises cylindrical part, and this cylindrical part at one end has flange end and is used for hub is connected to the link of armoured cable.The opening (being hole or axial hole) that cylindrical part has central axis, outer surface and extends between two ends.The coupling flange is connected to first end of hub and radially extends to outer perimeter from opening.Preferably, the coupling flange in outer perimeter has raised edges and cylindrical part opening and the match surface between the raised edges.When the flange end of body was admitted by the coupling flange, flange end was received in the raised edges of coupling flange, and the surface of flange end contacts with match surface.The link of hub has a plurality of screw threads on the outer surface to admit the screw thread of coupling nut.In preferred embodiment, the cylindrical part of hub comprises the peripheral groove that being suitable between first end and second end admits elasticity O shape to encircle.Be threaded onto on the hub and after crossing peripheral groove at coupling nut, elasticity O shape ring is installed in the groove to prevent that the flange end that coupling nut unclamps coupling flange and body from can throw off the position that is connected.Elasticity O shape ring is to be generally used for the type of electric fittings and can or to have the flexible synthetic material that is similar to rubber by elastomeric material making.
The coupling flange preferably arranges with about 30 to 60 degree angles with respect to the angled setting of the central axis of hub, and best with about miter angle setting.Because being obliquely installed of coupling flange, the part of coupling flange is positioned at the minimum distance of the link of hub, and relatively partly is positioned at the maximum distance apart of link.For purpose of the present disclosure, the part that is positioned at the link minimum distance of coupling flange is called " top " of hub, and the part that is positioned at the link maximum distance apart of coupling flange is called " bottom " of hub.The coupling flange has around outer perimeter along the dovetail that extends at least about 45 degree radians.Dovetail is designed at least a portion with the perimeter edge of the flange end of tongue and groove relation admittance body.In certain embodiments, dovetail can be around the distance of the outer perimeter extension of mating flange up to about half.
Screw thread second end of hub can be connected to armoured cable or it can be connected to shell by accessory.Preferably, hub having a pair of wedge shape with coupling flange outer surface adjacent and abut part at cylindrical part.Wedge shape abuts the relative position place that part is positioned at the cylindrical part of hub, and preferably is the wedge-shaped projection on the outer surface.Each wedge shape abuts part to be had corresponding to the roof at the top of hub with corresponding to the diapire of the bottom of hub.Thereby sidewall is substantially perpendicular to the prominent frame of their formation of outer surface of hub.Because wedge shape abuts part from extending towards the link of hub with coupling flange position adjacent, basal wall is inclined upwardly to provide wedge-type shape at least.In preferred embodiment, the basal wall that wedge shape abuts part has " step " structure, is not with continuous smooth and be inclined upwardly, and they are inclined upwardly with a plurality of steps.As hereinafter in greater detail, wedge shape abuts part and is suitable for cooperating with lug on the anchor clamps.
Anchor clamps have basal wall, and basal wall has the pair of sidewalls of extending from the opposite end.Preferably, basal wall and sidewall are crooked, thereby they can be similar to the crooked outer surface Continuous Contact of the cylindrical part of the mode of saddle and hub.Basal wall and sidewall respectively have a pair of opposite end and corresponding top, bottom, inboard and the outside.Sidewall substantially perpendicularly or with the angles greater than 90 degree extends to far-end from the inboard of the opposite end of basal wall and limits the inside of anchor clamps.Keeper extends up to the lip that extends towards inside from the top of basal wall.Lip has sunk part at base portion, and this sunk part is suitable for admitting the flange end of body and cooperates with it when body is connected with hub.
Lug with base portion and end extends from the top of the far-end of each sidewall.Lug can be substantial rectangular, but is preferably wedge shape, has along with lug extends the inboard that tilts away from basal wall one side of basal wall (namely towards) towards the end, and the opposite side of lug vertically extends from the top of sidewall basically simultaneously.After the coupling flange of the flange end of body and hub links, anchor clamps are installed on the top of hub, make that the lip of keeper is overlapping at top epirelief acies with coupling flange and body, and lug slides into wedge shape on the bottom and abuts the part below and cooperate with it.In another embodiment, hub do not have that wedge shape abuts part and when coupling nut is tightened against anchor clamps the lug of anchor clamps cooperate with the rear side of coupling flange.
Distance between basal wall and the lug is chosen to when anchor clamps are installed on the hub, and the flange end that links with the coupling flange of keeper and body is overlapping, and the end of link that lug and wedge shape abut the most close hub of part snugly contacts.In this structure, the diapire that wedge shape abuts part is inclined upwardly from the coupling flange along the top-direction of hub, and the inboard of lug is along the inclination that is directed downwards of the bottom of hub.Owing to being tightened with the edge, coupling nut applies power towards the direction of the coupling flange end of hub at anchor clamps from link, simultaneously because wedge shape abuts the incline structure of the correspondence of part and lug, the more close coupling flange of anchor clamps is also mobile along downward direction (namely from the top of hub towards the direction of bottom).This forces keeper to go up and force wedge shape to abut part and cooperate frictionally that with lug body and hub are fixed on the fixed position down to flange end/coupling flange connection.
This coupling nut has first end and second end, is extended with axial hole and inner surface at two ends.First end that inner surface has screw thread and nut is suitable for being admitted by the threaded ends of hub.Coupling nut also has the perimeter edge of extending around the circumference of axial hole on first end.First end adjacent with perimeter edge preferably has rough surface or a plurality of notch, cooperates with anchor clamps when this rough surface or notch are suitable on second end that coupling nut is threaded onto hub.
After the flange end of body is attached to coupling flange on the hub, coupling nut is tightened that body and hub are fixed on any desired angular relationship.Tighten the position at this, coupling nut snugly cooperates so that body and hub are locked on the desired orientation together against anchor clamps.This is called " tightening the position " or " latched position " here.When unclamping coupling nut slightly, the pressure on the anchor clamps reduces, thereby the body of connector and hub portion can be rotated to any angle orientation relative to each other.This is called " adjustable position " here.The slidably surface of flange end and coupling flange allows continuous 360 degree to rotate, and tightens that against anchor clamps body and hub are locked in selected angle orientation together again up to coupling nut.When connector is in adjustable position, further unclamps coupling nut so that anchor clamps and flange end and coupling flange disengage, thereby body and hub can be thrown off.This is called " disassembling the position " here.
In one embodiment, adjustable connector has two parts or part, and body and hub are respectively equipped with flange end and mate flange so that two parts are linked together in its corresponding mating end.The surface of flange end and coupling flange with respect to the longitudinal axis of body and hub preferably between 30 to 60 degree and best into about the angled extension of 45 degree.When body was connected to hub, the surface of flange end and coupling flange was fitted to each other slidably and rotationally.Coupling flange on the hub is provided with the dovetail that extends along the part of its perimeter edge, and this dovetail is with the edge of the flange end of dovetail or tongue and groove relation admittance body.Specifically, the outer surface at the edge of flange end slip on the complementary edge of mating flanges of hub dovetail and by its admittance.Anchor clamps are installed on the coupling flange of hub and with the flange end of body and contact, preferably in the position relative with dovetail.Coupling nut is installed on the end of thread of hub and tightens so that anchor clamps are fixing in place then.
Adjustable connector is especially favourable, because it can provide the zero deflection of each parts to axially align.Therefore, the two parts that pass accessory when cable all do not have skew or crooked till these two parts rotate to desired orientation.This provides favourable, is particularly useful for initial straight-through connection of large-diameter cable, and this cable more is difficult to bending and installation in accessory.In addition, adjustable connector can be thrown off easily, also is afterwards so even cable is installed in accessory, because straight-through connection of body and hub be convenient to throw off with directed again.
In preferred embodiment, the outer surface of dovetail can be provided with hand grip portion so that manual the installation.Hand grip portion can form by one or more juts or the rib that radially extends from dovetail, or this hand grip portion can or be recessed to form by the one or more slits in the dovetail.Adjustable connector can be made by metal or plastic material, preferably makes by molding process.In addition, adjustable connector can comprise by the self-draining ability of the osculum on the hub, and this makes that accessory can both draining when directed at any angle.
Hole on body and the hub can be provided with rounded internal surface is avoided sharp edges with the protection cable cutting or wearing and tearing.In addition, adapter can be provided with for the watertight O shape ring that connects between sealing two joint flanges.This O shape ring can be installed in the lip-deep circular groove basically of one of joint flange (preferably hub).
For bigger cable, can reduce joint flange with respect to the cable bending that provides more progressive of being obliquely installed of its longitudinal axis.Preferably, each flange end and the coupling flange that is used for these accessories of big cable has the surface that arranges with 22.5 degree rather than 45 degree with respect to longitudinal axis, so that the bending radius of increase to be provided.In this embodiment, two 45 degree adjustable connectors are used for providing 90 degree to connect.Each connector has coupling flange and flange end, and their surface forms 45 degree connectors with the surface that arranges with 22.5 degree with respect to longitudinal axis.Two connectors that are installed in series provide 90 degree to connect.
In another embodiment, between the body of adjustable connector and hub, connector is installed.One end of connector has the flange end that is similar to the flange end on the body, and the other end of connector has the coupling flange of the band dovetail of the coupling flange that is similar to hub.Flange end links in the mode identical with the coupling flange with hub epirelief acies with body with the coupling flange.The flange end of connector cooperates with the coupling flange of hub, and the coupling flange of connector cooperates with the flange end of body.Connector also can have at every end connector being connected to flange end on the hub.As the skilled person will understand, its each surface general be connected or specified configuration connects of can be used for providing any angle with the various combination of body, hub and the connector epirelief acies of various angle settings and coupling flange with respect to its axis.When coupling nut cooperates with anchor clamps and with flange end and coupling flange when being fixed together, three rotation XYZ and three kinds of rectilinear motion XYZ of the adjustable connector assembly of three members (hub, coupling nut and body) locking adjustable connector.
