Terminal and connector assembly for electrical cables

Claim 2

A cable terminal and connector device for effecting end-to-end connection of cables without requiring rotative alignment, said device comprising: first and second terminals each comprising a cylindrical terminal body having an axial cavity in which is fixable an end of a cable to be connected, a cylindrical stem extending from said terminal body axially away from said cavity, and a cylindrical knob formed on the end of said stem; a cylindrical connector body defining a recess opening through one side thereof and having inner semi-cylindrical surfaces complementary to said stems when in axial alignment, said connector body having a semi-cylindrical central enlargement to said recess that accommodates said knobs; said terminals being confined against axial movement in either direction by cooperation of said knobs and said terminal bodies with said connector body, whereby one or the other terminal can be individually assembled in said connector body without interference from the other terminal; a keeper element received in said recess of said connector body in clamped retaining relation to the stems and knobs of said first and second terminals, said keeper element having a central recess receiving a portion of said knobs whereby forces tending to axially separate said terminals are transferred to said connector body and to said keeper element; and fastening means for securing said keeper element in said clamped retraining relation; said fastening means comprising U-bolt means, and said keeper element and said connector body being provided with grooves and apertures for receiving said U-bolt means.

Claim 3

A cable terminal and connector device as defined in claim 1, and wherein: said terminals, said connector body, and said keeper element are formed of metallic conductor materials.

Claim 4

A cable terminal and connector device as defined in claim 2, and wherein: said terminals each comprise a radially extending flange extending from said body portion, said flange having a diameter substantially equal to the diameter of said connector body.

Claim 5

A cable end connecting assembly comprising in combination: first and second cable end terminals formed of metal and each comprising a cylindrical body portion of a first diameter and having a cavity in which a cable end is fixed, a flange extending radially from said body portion and having a second diameter, a cylindrical stem portion of a third diameter smaller than said first diameter and extending axially from said body portion away from said cavity, and a cylindrical knob formed on the distal end of said stem portion, said knob having a diameter greater than the diameter of said stem and smaller than the diameter of said flange; a generally cylindrical, rigid metal connector body having an outside diameter substantially equal to the diameter of said flange, said body having a length substantially equal to the distance between the flanges of said first and second terminals when axially aligned with the respective knobs adjacent one another, said body defining a recess along the length thereof and opening radially through the side thereof, said recess having end portions sized to receive said aligned terminal stem portions in closely fitting relation and having a central enlarged portion sized to receive said adjacent knobs in closely fitting relation; a keeper element disposed in said recess over said stem portions and said knobs, said keeper element having an outer surface substantially coextensive with the outer surface of said connector body and having an inner surface characterized by a central recess in which portions of said knobs are received, said inner surface of said keeper element having end portions bearing against said stem portions; and a plurality of threaded fastener elements extending between said connector body and said keeper element and operative to draw them together in clamping relation to said stem portions and said knobs.

Claim 6

A cable end connecting assembly comprising in combination: first and second cable end terminals formed of metal and each comprising a cylindrical body portion of a first diameter and having a cavity in which a cable end is fixed, a flange extending radially from said body portion and having a second diameter, a cylindrical stem portion of a third diameter smaller than said first diameter and extending axially from said body portion away from said cavity, and a cylindrical knob formed on the distal end of said stem portion, said knob having a diameter greater than the diameter of said stem and smaller than the diameter of said flange; a generally cylindrical, rigid metal connector body having an outside diameter substantially equal to the diameter of said flange, said body having a length substantially equal to the distance between the flanges of said first and second terminals when axially aligned with the respective knobs adjacent one another, said body defining a recess along the length thereof and opening radially through the side thereof, said recess having end portions sized to receive said aligned terminal stem portions in closely fitting relation and having a central enlarged portion sized to receive said adjacent knobs in closely fitting relation; a keeper element disposed in said recess over said stem portions and said knobs, said keeper element having an outer surface substantially coextensive with the outer surface of said connector body and having an inner surface characterized by a central recess in which portions of said knobs are received, said inner surface of said keeper element having end portions bearing against said stem portions; and a plurality of threaded fastener elements extending between said connector body and said keeper element and operative to draw them together in clamping relation to said stem portions and said knobs.
