Abstract
Abstract The disclosure relates to a one-piece metal clamp which is secured to a plastic connector housing having multiple electrical terminals for connection to respective wires contained in a multiple wire cable. The clamp is adapted to grasp the cable and anchor the same to the connector. The clamp is readily closed and secured on the cable without a need for a clasp. As a consequence, the clamp may be readily opened by prying with a suitable tool without incurring damage to either the clamp or the cable. The clamp is designed for preventing excessive closure on the cable and for preventing piercing or other damage to the cable.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
149 words
A one-piece metal strain relief clamp, comprising: a base portion for secure connection with a plastic connector housing having terminals for electrical connection to the wires of a multiple wire electrical cable, and a pair of arm portions each extending from said base portion and being doubled back upon itself by an enlarged loop portion so that an end portion of said arm portion is opposite the other end portion to define therebetween a cable receiving space of hour-glass section having one end closed by said base portion and an opposite open end closed off by convergence of said loop portions upon deflection of said arm portions toward each other, said end portions being between the remainder of said arm portions separating said cable receiving space from said remainder of said arm portions, and said loop portions being engageable with each other to prevent excessive closure against said cable.
Claim 2
Dependent Claim
