' DESCRIPTION OF THE PREFERRED EMBODIMENTS A connector assembly 10 constructed in accordance with the teachings of this invention is shown in FIGS. 1 through 4 and consists of hub 12, connector cone 14, jam nut 16, washer 18, sealing grommet 20 and sealing nut 22.
The hub 12 is generally circular and formed out of aluminum or other suitable electrically conducting material With a plurality of radially disposed, internally threaded spokes 24. The hub is provided with an insulating coating 26 such as durable hard vinyl by means of a dip coating process. Of course, other insulating materials can be used for coating or enclosing the hub and other means of attachment of the insulating material to the hub can be utilized in the practice of the invention.
A portion 26 of the insulating material extends within each of the spokes 24 covering a section of the internal threads 24'. The purpose achieved in continuing the coating within the edge portion of the spokes will become apparent below.
Each of the spokes is provided with a two sectioned bore. One bore section is cylindrical and indicated by the numeral 28 in the figures. The major portion of bore section 28 is provided with threads 24'. The second bore section is indicated in the figures by the numeral 30 and is conical in configuration with the cross-sectional diameter of the bore adjacent bore section 28 greatest in diameter but less in diameter than the diameter of bore section 28 providing an annular shoulder 32.
The jam nut 16 is formed of non-conducting material and has a hex nut central flange 46 with cylindrical por tions 48 and 50 extending from opposite sides thereof and providing a continuous longitudinal bore 52 which is flared outwardly slightly at 54 at one end. A major portion of the outer surface of flange 50 and a minor portion of the outer surface of flange 48 are threaded and the threads in the figures are indicated by the numerals 50" and 48' respectively. Jam nut 16 is preferably formed of a plastic material.
The sealing grommet 20 is also formed of a plastic material and in the preferred embodiment the material is soft plastic as compared to the harder plastic out of which the jam nut 16 and sealing nut 22 are formed. Flexible sealing grommet 20 is non-conducting and is provided with a central longitudinal bore 54 of uniform diameter and a section 56 at one end having a uniform outer diameter. The remaining section 58 of grommet 20 is provided with an outer diameter which decreases constantly to provide an outer conical surface having its greater diameter adjacent section 56.
The sealing nut 22 is also formed of non-conducting V material and has a threaded bore section 60' and a lesser diameter bore section forming annular shoulder 62. The outer surface of nut 22 is in hex configuration.
The means for attaching cable 42 to the hub 12- is shown in exploded view in FIG. 2 and the fully assembled condition in FIG. 3. In assembling or in attaching a cable to the connector the cable is prepared by skinning the insulation in the usual manner to expose stranded portion 40. The cable end is threaded through sealing nut 22, grommet 20, jam nut 16 and washer 18 and the exposed end 40 of the cable is inserted within connector cone 14.
Tightening of sealing nut 22 completes the water-tight seal by the annular shoulder 62 of sealing nut 22 forcing the sealing grommet 20 within the flared portion 54 of the bore of the jam nut.
It is noted therefore that each conductor can be individually connected to the hub assembly by mechanical tightening with a standard wrench to provide a permanent yet easily disconnected joint. The sealing nut provides a water-tight seal at the entrance of the cable to the connector and also provides ease of accessibility for disconnector re-entry into the joint.
The water-tight fully insulated assembly permits use with both aluminum and copper conductors.
In the embodiment shown in FIGS. 1 through 4 three spokes remain without a cable entering therethrough. In order to provide a completely insulated unit cylindrical cap 64 formed of non-electrically conducting material are inserted one within each of the spokes 24 not receiving a cable. Each of the caps 64 is provided with a conical body portion 66, a closed bottom 68 and a flange 70 for ease of insertion and removal. It is noted that the caps 64 are of uniform diameter and upon insertion are disposed within bore section 28 of spoke 24.
The completed phase and neutral connections may be stacked pancake fashion in position for ease of direct burial. Each pancake provides complete flexibility to direction of services and of conductor sizes. Hence in FIG. a connector 74 constructed in accordance with the teachings of this invention is shown stacked upon other connectors which are shown diagrammatically and phantom lines and indicated generally by the numerals 76, 7 8 and 80. Means can be provided for affixing the connectors 74, 76, 78 and 80 to one another or they can be merely disposed in stacked position.
An alternate means for providing a seal between a cable and the assembly is shown in FIGS. 6 through 7. The jam nut 116 is equipped with a heat shrinkable silicone rubber tubing 82 to provide the outer seal of the assembly to the cable jacket 142. In this embodiment the shrinkable sleeve 82 is first attached to the flanged section 150 of jam nut 116 by heat shrinking and the cable 142 which has been skinned to expose strands 140 is inserted through the bore of jam nut 116 and the end 140 disposed within connector cone 114. In this embodiment the jam nut 116, connector cone 114, washer 118 and spoke 124 are of the same configuration as in the previous embodiment and in the fully assembled condition the washer is in firm contact with the insulation 126 on the end of the spoke 124 and connector cone 114 is firmly gripping cable end 140.
The remaining portion of tubing 82 is then heat shrunk to firmly embrace the outer surface of cable 142 providing a firm seal therewith.
Other types of shrinkable tubing can be used in the embodiment disclosed in FIGS. 6 and 7 including the tubing which is shrinkable by application of chemicals.
Alternate embodiments of the invention are shown in FIGS. 812.
In FIG. 8 the connector includes a body 200 having four outlets 201, 202, 203 and 204 disposed at right angles to one another and the body and outlets are coated with an insulating material as in accordance with the embodiment shown in FIGS. 1 through 7.
In FIG. 9 a two outlet connector 205 is shown which is also coated as in accordance with the previous embodiments.
In FIG. 10 a four outlet connector 206 is shown having a feeder 207 and 3 tapons 208, 209 and 210 and as with the previous embodiments, the body and arms of the connector are coated with a suitable insulating material.
In FIG. 11 a four outlet dome-type connector having insulating coating is shown and indicated by the numeral 211 with the arms indicated by the numerals 212, 213, 214 and 215 respectively.
In FIG. 12 connector 216 is provided with arms 217, 218, 219 and 220' forming a type of table. The connector 216 as is the case with the connectors previously described, is coated with a non-conducting or insulating material.
Additional or fewer outlets can be provided on the various connectors shown and described.
Thus, among others, the several objects of the invention, as specifically aforenoted, are achieved. Obviously, numerous changes might be resorted to without departing from the spirit of the invention.
