Abstract

Knife edged contactors resiliently mounted on a wedge cam produce a slicing contact with the tip of a pin contact. The contactor actually slices into the pin, cutting through oxide or coating to make good electrical contact with clean metal.

Slicing Contactor

Knife edged contactors resiliently mounted on a wedge cam produce a slicing contact with the tip of a pin contact. The contactor actually slices into the pin, cutting through oxide or coating to make good electrical contact with clean metal.

Frame 1 contains contact pin 2 which is to be connected temporarily. Contactor 3, mounted slidably in plastic block 4, is backed by a soft foam rubber cushion 5 so it can slide upwardly and backwardly as a result of slight pressure against the knife edge of contactor 3. Cushion 5 is faced with a toughened layer adjacent contactor 3 to prevent wear.

In operation, block 4 is moved toward frame 1 until the knife edge of contactor 3 touches the tip of pin 2. The block is then moved additionally. Pin 2 exerts force against contactor 3 which slides upwardly and backwardly against cushion 5. As contactor 3 slides upwardly, its knife edge moves slightly with respect to pin 2, slicing through the skin of the pin into clean metal. Wire 6 connects contactor 3 to other devices as required.
