Abstract

This connector, as shown in the drawing, comprises individual one-piece. double contacts 3 which are inserted into a fixed body 7 and retained in place by being spring loaded around a retaining rib 8. The upper formed ends of the contacts 3 are designed to make contact with the pins 2 of the product to be tested. The bottom formed ends of the contacts 3 are designed to make contact with pins 4 in a printed-circuit board, not shown.

Enhanced Zero Insertion Connector

This connector, as shown in the drawing, comprises individual one-piece. double contacts 3 which are inserted into a fixed body 7 and retained in place by being spring loaded around a retaining rib 8. The upper formed ends of the contacts 3 are designed to make contact with the pins 2 of the product to be tested. The bottom formed ends of the contacts 3 are designed to make contact with pins 4 in a printed-circuit board, not shown.

The upper and/or lower ends of contacts 3 are independently actuated by moving the actuation plates 6 in opposite directions, thereby closing the normally sprung open contacts 3 against the product pins 2 and/or the printed-circuit board pins 4.

This is a true zero insertion connector, no side thrust is required on the module or module pins 2 to actuate the contacts. Mechanical contact is made against opposite sides of each pin 2, 4, thereby "neutralizing" the resultant force. Actuator plates 6 as well as the fixed body 7 and protective covers 5 are made from FOTOCERAM*. All holes are chemically machined in the FOTOCERAM which reduces tooling and fabrication costs. FOTOCERAM is an excellent insulator with a low thermal coefficient of expansion, which makes it particularly useful in connector aging applications.

Protective covers 5 prevent damage to contacts 3 should pins 2 or 4 be misaligned for insertion into the connector assembly. By removing protective covers 5, each contact 3 is individually repla...
