Abstract: Zero insertion and extraction force connector clip for connecting conductors on a thin film to conductors on a circuit board comprises a one-piece stamped and formed member having a rectangular clip bar and means at each of its ends for mounting the clip on a circuit board in straddling relationship to the circuit board conductors. A plurality of contact springs extend from one edge of the clip bar. Each spring is reversely bent at the one edge and has a spring arm portion extending obliquely underneath the clip bar so that when the clip is mounted on the circuit board, contact portions of the springs will be against the circuit board conductors. The ends of the springs have toolengageable portions which can be engaged by a uniquely suited tool. The tool functions to raise the springs from the circuit board so that the film can be inserted between, and extracted from, the circuit board and the springs with zero force on the film conductors.

Abstract: Apparatus for installing connectors on the ends of cables comprises first and second reciprocable rams which are coupled to each other by compressible coupling means. Connector deforming tools are mounted on the first ram which inwardly deform portions of the connector thereby to clamp the connector to the cable. Contact insertion tool means are mounted on the second ram and function to push contact members through the connector housing and into the wires of the cable. The arrangement is such that the deforming tools dwell in their lowered position and support the connector housing while the insertion tools drive the contact members through the housing. This arrangement prevents unwanted deformation of the housing while the contact members are being driven therethrough. The apparatus is also provided with improved aligning means which functions to align the connector with the deforming tools and the insertion tools.
