Abstract
A pin grip array zero insertion force connector has 10,000 or more normally closed contacts provided in rows on a motherboard. Alternating rows of contacts respectively include first and second type contacts, and drawbars are provided between the rows of contacts. Alternate drawbars are caused to slide in opposite directions, thereby engaging the drawbars with one of the two tines of each contact in the rows of contacts on either side of the drawbar. An actuator mechanism is provided at each end of the rows of contacts and drawbars to engage and slide the drawbars. To reduce the force necessary to operate each actuator mechanism, the actuator mechanisms may be divided into subactuator mechanisms which are individually actuated. The drawbars comprises a drawbar support strip which engages the actuator mechanisms and an interposer body molded to retaining tabs on the drawbar support strip.
