Abstract

A test clip having opposed spring closed jaws has one electrically conducting jaw and an opposed jaw with a yieldable and deformable surface capable of conforming to the shape of a wire or terminal to which the clip is attached. The yieldable surface has a high coefficient of friction.

Claims

1. A test clip having opposed spring pressed clamping arms, ONE OF SAID ARMS HAVING A BARE ELECTRICALLY CONDUCTING CONTACT JAW, MEANS ON SAID CLIP FOR MECHANICALLY CONNECTING AN ELECTRICAL CONDUCTOR THERETO AND IN ELECTRICAL CONTACT WITH SAID ONE ARM AND ITS JAW, AND A PAD OF YIELDABLY DEFORMABLE MATERIAL ON THE OTHER OF SAID ARMS FORMING A SECOND JAW POSITIONED TO ENGAGE THE SURFACE OF A CONDUCTOR ENGAGED BETWEEN SAID JAWS, SAID PAD HAVING A SURFACE WITH A HIGH COEFFICIENT OF FRICTION.

2. A test clip as defined in claim 1 in which said pad is secured to a portion of said other arm which is opposed to said bare electrically conducting jaw.

3. A test clip as defined in claim 2 in which said pad is a sleeve of rubber stretched over its supporting clamp arm.

4. A test clip as defined in claim 2 in which said pad is formed of rubber and has a projection extending through an opening in its supporting arm to hold the pad in place.

5. A test clip as defined in claim 2 in which said pad is adhered to the surface of its supporting clamp arm.

6. A test clip as defined in claim 2 in which said pad extends along its supporting arm for a distance several times the length of said electrically conducting jaw.
