Abstract

A contact leaf bank for an electrical contactor preferably etched from a single uniform sheet of resiliently flexible, electrically conductive material comprises a ground sheet defining a plurality of uniformly-spaced, elongated, parallel slots in which are singularly disposed a plurality of resiliently flexible, elongated leaves each having and end portion adapted to be a contact finger, the tip of each contact finger preferably being rhodium-plated for hardness. A pair of spaced and opposing contact leaf banks are two elements of a contact assembly which further comprises a base member in which a base end of each contact leaf bank is anchored, a device rail which in one form is a single track upon which an electrical device rides is centrally interposed between the contact leaf banks, the device rail being adapted to seat a device such that side leads of the device are aligned with the contact fingers and the spacing of the contact banks being such that the banks can be bent inboardly to make wiping contact between the device leads and the contact fingers, a pair of rockers one affixed to each bank at an end opposite the bank's anchored end and adapted to be reciprocatingly rocked or rotated toward and away from the device rail by an over-travel compensated actuating mechanism, the portion of each contact leaf bank between its respective rocker and the base member acting as a resilient hinge, and connector adaptors housed in the base member for providing electrical communication between the contact fingers and connectors also housed in the base member.
