Abstract

A cable clamp includes a housing having a cavity therein with two opposed walls and an open end in communication with the cavity. A pair of wedge shaped jaws are located within the housing and are slideably movable toward and away from the opening. Each of the jaws includes a semi-cylindrical gripping surface which are adapted to move toward each other to grip a cable therebetween when the jaws move toward the opening and are able to move away from each other when the jaws move away from the opening so as to release a cable located therebetween. A spring biases the jaws toward the opening so that they are biased into the gripping position. In order to more positively hold the cable, each of the gripping surfaces includes a plurality of teeth in the form of raised segments of spiral threads. Some of the spiral threads on each of said inserts are right handed and some are left handed to help prevent rotating movement of the cable as it is being gripped. The clamp can be used as a dead end clamp or the housing can contain a second pair of jaws, preferably extending in opposite directions, whereby the clamp is capable of gripping a second cable for electrically and mechanically connecting two cables together.

16. A cable clamp for electrically and mechanically connecting two cables together comprising:

a housing comprised of first and second U-shaped members, each member comprised of two opposed walls but being substantially open on two sides thereof, a first cavity having a first opening in communication therewith located in said first member and a second cavity having a second opening in communication therewith located in said second member, said first and second openings being in substantial axial alignment with each other but facing in opposite directions, each of said cavities being visible from both sides of said housing so that cables passing through said openings are visible from outside said housing;

first and second yokes, said first yoke surrounding said two opposed walls of said first U-shaped member adjacent said first opening and said second yoke surrounding said two opposed walls of said second U-shaped member adjacent said second opening;

first and second pairs of jaws located within said housing, said first pair of jaws being movable toward and away from said first opening and said second pair of jaws being movable toward and away from said second opening, each of said jaws including a wedge-shaped outer surface and a semi-cylindrical gripping surface, said gripping surfaces of each pair of jaws being adapted to move toward each other to grip a cable therebetween when said jaws move toward their respective opening and are able to move away from each other when said jaws move away from their respective opening so as to release a cable located therebetween, and biasing means biasing said jaws toward said openings.

17. The cable clamp as claimed in claim 16 wherein said biasing means are comprised of coil springs.

18. The cable clamp as claimed in claim 16 wherein each of said gripping surfaces includes a plurality of teeth for gripping said cable.

19. The cable clamp as claimed in claim 18 wherein said teeth are in the form of raised segments of spiral threads.

20. The cable clamp as claimed in claim 19 wherein some of the spiral threads are right handed and some are left handed.

21. The cable clamp as claimed in claim 16 further including means for temporarily maintaining each of said pairs of jaws away from each other prior to the insertion of a cable therein in order to assist in the insertion of said cable.
