Abstract

An improved connection apparatus that meets these and other needs includes, in one embodiment, an approximately J-shaped flexible conductor having at its end an opening that receives therethrough a portion of the shank for mechanical and electrical connection therebetween. The conductor further includes a hole formed therein at approximately its midpoint that receives therein, in a movable and non-contacting fashion, another portion of the elongated shank. In another pair of embodiments, another connection apparatus includes a flexible conductor that is co-formed with a rigid conductor to form a single piece unitary element. The free end of the flexible conductor is connected with the movable shank, and the rigid conductor is connectable with the primary conductor of the circuit. By providing the flexible conductor and the rigid conductor as a co-formed unit, a detachable fastener need not be employed to provide a connection therebetween, which reduces heat generation.

First claim

What is claimed is:

1. A connection apparatus structured to be electrically connected between a movable conductor of a circuit interrupter and another conductor that is stationary, the movable conductor having an elongated shank that is structured to be connected with an operating mechanism which is structured to move the shank along a movement axis to change the state of the circuit interrupter, the connection apparatus comprising:
an elongated and flexible conductor having formed therein a hole that is elongated along a direction of elongation of the conductor and that is structured to movably receive therein a portion of the shank in a generally non-contacting fashion;
a first end of the conductor forming a first connecter and having formed therein an opening that is structured to receive therein another portion of the shank and to be electrically connected with the another portion of the shank; and
a second connector situated at a second end of the conductor and being structured to be electrically connected with the another conductor.

2. The connection apparatus of claim 1 wherein the conductor includes an approximately U-shaped loop portion having a pair of legs and further includes an elongated connection portion that extends from a leg of the pair of legs.

3. The connection apparatus of claim 2 wherein the hole is formed in the leg, and wherein the first connector is situated on another leg of the pair of legs.

4. The connection apparatus of claim 3 wherein the second connector is situated at an end of the connection portion opposite the leg.

5. The connection apparatus of claim 2 wherein the loop portion and the connection portion together are approximately J-shaped.

6. The connection apparatus of claim 1 wherein the conductor is a braid formed of a conductive material.
