Abstract

The present invention provides an electrical connector clip comprising: two insulating body portions secured together about a pivot so as to provide handle portions at one side of the pivot and gripping portions at the other side of the pivot, said gripping portions being biassed towards each other by an electrically conducting spring mounted around the pivot and extending along said gripping portions; at least the outer end of each said gripping portion being provided with a replaceable jaw made of electrically conducting material, each said jaw being dimensioned and arranged to be in electrical contact both with said spring and with any article gripped between said gripping portions.

Claims

1. An electrical connector clip comprising:

two insulating body portions secured together about a pivot so as to provide handle portions at one side of the pivot and gripping portions at the other side of the pivot, said gripping portions being biassed towards each other by an electrically conducting spring mounted around the pivot and extending along said gripping portions;

at least the outer end of each said gripping portion being provided with a replaceable jaw made of electrically conducting material, each said jaw being dimensioned and arranged to be in electrical contact both with said spring and with any article gripped between said gripping portions.

2. The clip as claimed in claim 1, wherein each body portion is substantially rectangular in plan and each of the longer sides of said rectangle is provided with a boss which lies in a plane substantially perpendicular to the plane of said body portion;

both said bosses being co-axial and apertured to receive said pivot therethrough.

3. The clip as claimed in claim 1 wherein each said body portion is shaped so as to permit either end of said body portion being used as either the handle portion or the gripping portion.

4. The clip as claimed in claim 2 wherein both said body portions are identical.

5. The clip as claimed in claim 4, wherein each body portion is formed with a peripheral rim which provides side walls along the longer sides of said rectangle, and end walls along the shorter sides of said rectangle;

one of said side walls having a first boss formed thereon, co-planar with said side wall, and the other of said side walls having a part-circular socket formed therein, of the same radius of curvature as said first boss; and

a second boss having a larger radius of curvature than said first boss being formed adjacent said other side wall;

said first and second bosses and said socket all being co-axial, such that when the two body portions are assembled to form a clip, the first boss of each body portion is received into the socket of the other body portion, the two second bosses lie one on each outer side of the clip, and a pivot pin extends through the aligned apertures in said first and second bosses.

6. The clip as claimed in any preceding claim wherein each jaw is U-shaped in cross-section and is a press-fit over the end of the corresponding gripping portion, each said jaw providing a serrated portion arranged to lie between the opposed gripping portions of the clip.

7. The clip as claimed in claim 6 wherein part of each jaw passes into the interior of the clip through a slot formed in the corresponding body portion, and is secured to connection means for providing an electrical connection between said jaw and a wire to be connected to the clip.

8. The clip as claimed in claim 6 wherein each jaw provides at least two spaced serrated portions.

9. The clip as claimed in claim 8 wherein the serrated portions on one jaw are staggered relative to the serrated portions on the other jaw.

10. The clip as claimed in claim 6 wherein the serrated portion of each jaw is pivoted to said jaw.

11. The clip as claimed in claim 1 wherein each body portion provides securing means for securing to said body portion a wire to be electrically connected to said clip.

12. The clip as claimed in claim 4 wherein said pivot pin comprises a generally cylindrical pin dimensioned to be a push-fit into said apertures, and formed with spaced projections on the exterior surface thereof to engage the side walls of the body portions and prevent the pin from sliding out of engagement therewith;

said pin also being formed with cut-out portions in the interior thereof, aligned with said projections, to allow the pin to contract radially during assembly of the clip.
