The connector is fabricated from an insulating outer sleeve having a plurality of apertures which extend from the outer surface thereof to the inner surface thereof and which are adapted to be sealed after the connector is assembled to conductors by means of plugs placed in the aperture so as to form a continuous insulating outer sleeve. Concentrically mounted within the outer sleeve is a metallic inner sleeve having a wire stop in the center thereof to limit the insertion of the bared ends of the electrical conductors. In a first embodiment, the rigid inner metallic sleeve has a plurality of threaded apertures each receiving a set-screw in aligned position with the apertures extending through the outer sleeve. An appropriate tool may be introduced through the outer sleeve to engage the setscrews and permit their tightening upon a conductor placed within the connector to join the two. In a second embodiment of the invention the inner metallic sleeve is formed of a deformable material such that the indenter of a crimping tool may be inserted through the outer sleeve and operated so as to deform the inner metallic sleeve into intimate engagement with the conductors placed within the connector.

6 Claims, 2 Drawing Figures so so PRE-INSULATED CONNECTOR Fon ELECTRICAL CONDUCTORS BACKGROUND OF THE- INVENTION ductors to be joined. This is followed by the taping of I the joint thus produced employing numerous layers of tape to provide a sealabouttheconductors which is both waterproof and dirtproof and which insulates the cable from adjacent phases of the power lines carried within the same cable vault. It is not uncommon for a single phase,of a three phase line, to take eight hours to complete the taping requiredand itis not possible to tell at that timewhether or not the joint is good. Upon the loading of the cable, that is, applying full voltage to all phases of the cable,small pin holes within the tape itself might cause arcing or corona discharge which would be destructive to the cable, the vault and the surrounding area. Also,even if the cable joints were good when completed, the presence of dirt, moisture, ozone, or other gases or chemicals in the cable vaults as the cable joints were exposed to their environment for a period of time often caused breakdowns.

SUMMARY OF THE INVENTION The present invention seeks to overcome the difficulties noted above with respect to prior art devices and techniques by providing a splice or connector for joining cables to be placedin underground cable vaults or to be used overhead, which can be pretested and whose dielectric strength is known'prior to the time that such cables are connected by means of the connector. This is accomplished by providing a metallic inner sleeve which will receive the cables to be joined, an outer insulating sleeve, the integrity and dielectric strength of which can be determined by suitable testing. Operating devices are then introduced through apertures in the outer insulating sleeve to operate upon the inner metallic sleeve to cause it to intimately engage the conductors and thereafter the apertures are sealed with suitable insulating plugs to form a continuous insulating sleeve about the inner metallic sleeve.

More particularly, the outer insulating sleeve has a plurality of apertures extending from an outer surface to the inner surface thereof, each of which can receive a plug of similar material which can be fastened, cemented or otherwise adhered thereto to form a continuous insulating sleeve. Contained within and concentrically mounted with respect to the outer insulating sleeve is an inner metallic sleeve of somewhat shorter dimension than the outer insulating sleeve. The outer insulating sleeve has a central passage therethrough large enough to receivesuch metallic sleeve and the portions that extend beyond the metallic sleeve have passages'of somewhat smaller diameter such as to receive and intimately engage the outer insulating layer of the conductors themselves. In a first embodiment,

the inner metallic sleevehas a plurality of threaded apertures extending from its outer surface to its inner surface. Contained within each of the threaded apertures of the inner metallic sleeve is a set-screw too which access can be gained through the aligned apertures extending through the outer insulating sleeve. A tool, such as a screwdriver or the like, is inserted through the apertures in the outer insulating sleeve to engage the slot of the set-screw andoperate same until intimate engagement is produced between the inner metallic sleeve and the bared ends of the conductors inserted within the connector. Thereupon, plugs are inserted through the apertures of the outer insulating sleeve in order to form the desired continuous insulating sleeve about the metal sleeve.

In a second embodiment, the inner metallic sleeve is formed of deformable metal and is contacted by means of the indenter of a suitable tool place through the apertures in the outer insulating sleeve. The operator will cause deformation locally of the inner metallic sleeve to cause interengagement between such inner metallic sleeve and the conductor. In a similar fashion, plugs are positioned in the apertures of the outer insulating sleeve to complete the outer. insulating sleeve. It is therefore an object of this invention to provide an improved connector for electrical conductors.

It is another object of this invention to provide a preinsulated connector for electrical conductors.

It is yet another object of this invention to provide a reusable preinsulated connector for electrical conductors.

It is still another object of this invention to provide a preinsulated connector for electrical conductors the integrity of which can be preserved after the connector has been installed to the conductor.

It is still another object of this invention to provide a set-screw operated preinsulated electrical connector for electrical conductors.

It is yet another object of this invention to provide a suitable crimpably applied preinsulated electrical connector for electrical conductors.

Other objects and features of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principles of the invention and the best modes which have been contemplated for carrying them out.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings in which similar elements are given similar reference characters.

FIG. 1 is a side elevational view, in section, of a connector constructed in accordance with the concepts of the invention installed to two fragmented electrical conductors.

FIG. 2 is a side elevational view, in section, of a second form of electrical connector constructed in accordance with the concepts of the invention installed upon two fragmented electrical conductors.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning now to FIG. 1 there is shown a connector 10 constructed in accordance with the concepts of the invention. Connector 10 is used to join together two electrical cables 12 and 14 which have their outer insulating layer removed to expose a portion of the conductors l6 and 18 respectively. Connector 10 is constructed of an outer insulating sleeve 20 having a plurality of apertures 22 extending from the outer surface 24 to the in'riersurface26 thereof. The central'portion metallic sleeve, as willbe discussed below. The ends 30 of the outer insulating sleeve tapers to provide a smooth transition-between the insulating jacket of the cables 12 and 14 and the outer surface of the insulating sleeve 20. Contained therein are second passages of decreased dimension D2 sufficient to accept therein the outer insulating layer of the cables 12 and 14 and which prevent the inner metallic sleeve from being removed. Contained within the central passage 28 of the outer insulating sleeve 20, is an inner metallic sleeve 34 having a central passage 36 therein sufficient to accept the bared conductive portions 16 and 18 of the cables 12 and 14. A wire stop 38'divides central passage 36 of the metallic inner sleeve 34 into twoportions so that equal forces may be appliedto both of the conductors l6 and 18 inserted equally within the connector 10. In a first wall of the inner metallic sleeve 34 is a plurality of threaded apertures 40, in which is placed a setscrew 42 having a slot 44 arranged to be. engaged by atool such as a screwdriver 46 and rotated in the direction of the arrows,48 to advance or retract the set-screw 42 from within the aperture 40. Rotating the set-screws 42 in the direction to advance them into the central passage 36 causes them toengage theconductor l6 and 18 of the cables 12 and 14 and thus assemble the inner metallic sleeve 34 to said conductors l6 and 18. A plug 50, constructed of material similar to the material of which the outer insulating sleeve 20 is constructed, is then placed ,in each of the apertures 22 to seal them. The material used is usually rubber and may, if desired, have a semi-con layer on the outer surface thereof similar to the semi-con layer usually found upon cables such as 12 and 14. Plugs 50 may be made oversized and l6 and 18 thereof. The cables 12 and 14 are then inserted so as to position bare conductors l6 and 18 to either side of the wire stop 38 of the inner sleeve 34. A screwdriver such as 46 is then inserted successively through the apertures 22 of the outer insulating sleeve 20 to engage the slots 44 of the set-screws 42 tightening each against the conductors l6 and 18 of the cables 12 and 14. When this is completed the screwdriver'46 is removed and a plug 50 positioned in each of the apertures 22 to seal the outer insulating sleeve 20. By pretesting the connector 10, that is, before installation, it can be told in advance whether or not it will produce a complete joint, electrically and mechanically sound, prior to the time it is actually installed.

If it is desired, the connector of FIG. 1 may be reused by prying out, or removing, the plugs 50, inserting a screwdriver 46 within the apertures 22 and backing off Y each of'the set-screws 42. Thus, the connector 10 of FIG. -1 may be employed as a temporary or permanent connector and may be used as a repair device, if such 1 be necessary.

Turning now to FIG. 2 a permanent type of connector 60 is shown' for joining the bared conductorportions 16 and 18 of two cables 12 and 14. The outer insulating sleeve 20 is constructed in a manner similar to that described with respect to the insulating sleeve 20 of FIG. 1. Inner metallic sleeve 62 is different than that of the inner metallic sleeve 34 of FIG. 1 in thatythe inner metallic sleeve 62 of FIG. 2 isconstructed of a deformable material such as heat treated aluminium such that .it may be readily deformed by .the introduction of the indenter 64 of a suitable tool through each of the apertures 40 extending through the outer insulating sleeve 20. As is shown in FIG. 2, there is an indented area in the inner metallic sleeve 62 adjacent each one of the apertures 40 extending through the outer insulating sleeve 20. Wire stop 66 is provided in the central portion of the inner metallic sleeve 62 to limit'the insertion of each of the bared conductor portions 16 and 18 of the two cables, 12 and 14 respectively. Upon completion of the crimping of the individual conductors 16and 18 to the metallic sleeve 64, the plugs 50 will be placed in each of the apertures 40 as was described above with respect to FIG. 1 to provide an integral fully insulatingsleeve about the joint between thecables l2 and 14.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to the preferred embodiments, it will be understood that various omissions and substitutions andchanges of the form and details of the devices illustrated and in their operation may be made by those skilled in the art, without departing from the spirit of the invention. 1 5
