Abstract

A connector for a module must reliably engage a large number of small, closely-spaced pins, and in some cases, such as for test equipment, must operate satisfactorily for many cycles. The connector must also be tolerant to variations in the locations of the module pins.

Zero Insertion Connector for Liquid Encapsulated Module

A connector for a module must reliably engage a large number of small, closely-spaced pins, and in some cases, such as for test equipment, must operate satisfactorily for many cycles. The connector must also be tolerant to variations in the locations of the module pins.

The basic parts of a connector having the above advantages are shown in Fig. 1. The connector has a number of contacts 10 with one end of each mounted in a fixed upper plate 12, which locates the modules, and the other end connected to a movable lower plate 22, the "actuator plate". An end 16 of the J- shaped wire contact 10 is inserted into a clearance hole 18 in the fixed plate 12 so that it can freely pivot therein. The long leg L1 of the J-shaped wire contact 10 freely projects down through a relatively large hole 20 in the plate 12, terminating in a lower actuator plate 22. The connection of the contact 10 to the lower plate 22 is fixed so that it does not pivot.

Operation of the contact is obtained by moving the actuator plate 22. This imparts a linear motion to the end of the contact attached to plate 22. This in turn causes the upper portion of the contact to pivot in its restraining hole 18, thereby, angularly deflecting the upper leg ' L2 of the contact. This leg is relatively short and stiff, and when rotated makes contact with the module pin 24.

The leg L1 of the contact 10 is made relatively long and flexible (L1 >>> L2). It acts...
