Abstract

A wedge connector for mechanically securing two electrical cables and making them electrically common is disclosed. The wedge connector has a C-shaped body member and a wedge. The body member has sides that converge toward a first body member end from a second body member end. The body member has edges that are formed to define a pair of inwardly facing channels connected by a web extending between the channels. The wedge also has converging sides to be conformably received in the C-shaped body member. The wedge has concave, outwardly facing surfaces on each side connected by a web extending between the sides. It also has a spring rib formed in the web that extends continuously from a first wedge end toward a second wedge end.

Claims

1. A wedge connector comprising:

a C-shaped body member having sides converging toward a first body member end from a second body member end and having edges formed to define a pair of inwardly facing channels along respective sides connected by a web extending between the channels; and

a wedge having sides converging toward a first wedge end from a second wedge end to be conformably received in the C-shaped body member, the wedge having concave, outwardly facing surfaces on each side connected by a web extending between the sides, the wedge further having a spring rib formed in the wedge web, the spring rib extending continuously from the first wedge end toward the second wedge end opposite the first wedge end,

wherein the wedge, when conformably received in the C-shaped body member is positioned to mechanically secure a cable between the inwardly facing channel of the C-shaped body member and the concave outerwardly facing surface of the wedge.

2. The wedge connector of claim 1, wherein the wedge member includes a single spring rib.

3. The wedge connector of claim 1, wherein the spring rib has a width that changes as the distance from the first wedge end increases.

4. The wedge connector of claim 3, wherein the spring rib has a width that increases as the distance from the first wedge end increases.

5. The wedge connector of claim 1, wherein the rib extends continuously from the first wedge end toward the second wedge end a distance greater than one half the length of the wedge.

6. The wedge connector of claim 1, wherein the rib extends continuously from the first wedge end toward the second wedge end to a feature extending outwardly away from the wedge web toward the body member web.

7. The wedge connector of claim 1, wherein the C-shaped body member wedge includes a receptacle to receive a feature extending outwardly away from the wedge web.

8. The wedge connector of claim 1, wherein the C-shaped body member'"'"'s inwardly facing channels include extensions that extend rearwardly away from the body member web.

9. The wedge connector of claim 1, wherein the C-shaped body member'"'"'s inwardly facing channels are of a length greater than that of the body member web.

10. The wedge connector of claim 1, wherein a surface of the C-shaped body member'"'"'s inwardly facing channels are coated with a dry film lubricant.

11. The wedge connector of claim 1, wherein the concave, outwardly facing wedge side edge surfaces are coated with a dry film lubricant.

12. A wedge connector comprising:

a C-shaped body member having sides converging toward a first body member end from a second body member end and having rolled over edges formed to define a pair of inwardly facing channels along respective sides connected by a web extending between the channels, the channels having extensions diverging rearwardly away from the second body member end; and

a wedge having sides converging toward a first wedge end from a second wedge end to be conformably received in the C-shaped body member, the wedge having concave, outwardly facing surfaces on each side connected by a web extending between the sides, the wedge further having a single spring rib formed in the wedge web, the spring rib extending continuously from the first wedge end toward the second wedge end,

wherein the wedge, when conformably received in the C-shaped body member is positioned to mechanically secure a cable between the inwardly facing channel of the C-shaped body member and the concave outerwardly facing surface of the wedge.

13. The wedge connector of claim 12, wherein the single spring rib has a width that increases as the distance from the first wedge end increases.

14. The wedge connector of claim 12, wherein the wedge is conformably received in the C-shaped body member to mechanically secure a cable having any diameter in the range of about 16 mm to about 21 mm.

15. The wedge connector of claim 12, wherein the wedge is conformably received in the C-shaped body member to mechanically secure and electrically common two cables of the same diameter.

16. The wedge connector of claim 12, wherein the C-shaped body member has an inwardly facing channel surface coated with a dry film lubricant.

17. The wedge connector of claim 12, wherein the concave, outwardly facing side edge wedge surfaces are coated with a dry film lubricant.

18. The wedge connector of claim 12, wherein the sides of the wedge converge at an angle greater than an angle at which the sides of the C-shaped body member converge.

19. The wedge connector of claim 12, further comprising a plurality of teeth longitudinally spaced along the inwardly facing body-member channels.

20. The wedge connector of claim 12, wherein the sides of the wedge are chamfered.
