Abstract

With today's high technology computer systems being limited in peripheral communications by the I/O connector size and density, it became necessary to provide a high density connector system with a means to reduce the high insertion forces common to high density connectors. This article describes a zero insertion force connector system with high connector density which requires no tools for actuation. The high density zero insertion force connector system (Figs. 1 and 2) utilizes a manually actuated cam 2 which supplies the necessary pressure to the contact springs 1 in order to create a wipe action and contact pressure. The cam 2 is made of TEFLON*-filled DELRIN*, molded around a steel shaft 3. It is positioned in a housing 7 and pivots at each end of the housing.

High Density Zero Insertion Force Cam-Actuated Micro-Connector System

With today's high technology computer systems being limited in peripheral communications by the I/O connector size and density, it became necessary to provide a high density connector system with a means to reduce the high insertion forces common to high density connectors. This article describes a zero insertion force connector system with high connector density which requires no tools for actuation. The high density zero insertion force connector system (Figs. 1 and 2) utilizes a manually actuated cam 2 which supplies the necessary pressure to the contact springs 1 in order to create a wipe action and contact pressure. The cam 2 is made of TEFLON*-filled DELRIN*, molded around a steel shaft 3. It is positioned in a housing 7 and pivots at each end of the housing. An actuation bar 10 is fixed to the end of the shaft and rotates the cam 92OE to apply the necessary contact pressure during actuation. In the off position 16, the cam is free of the contact springs and no contact is made. By rotating the actuation bar 10 counterclockwise 92OE, the contact springs are activated and the actuation bar swings past the 90OE high point on the cam and is held in the actuated position by this pressure against the stop ledge 15. This action keeps the contacts engaged. During the connector activation, the spring contacts 1 wipe the contact tabs 4 in an upward motion under pressure in order to obtain a good el...
