Abstract

The connector as shown in Fig. 1, consists of rows of double contacts 2 bonded to insulator strips. The upper formed ends of the double contacts 2 are designed to make contact with the pins 3 of the product to be tested. The bottom ends of the contacts are designed to make contact with the test equipment board 4 (shown in Figs. 2 and 3).

High Density Double Contact Zero Insertion Force Connector

The connector as shown in Fig. 1, consists of rows of double contacts 2 bonded to insulator strips. The upper formed ends of the double contacts 2 are designed to make contact with the pins 3 of the product to be tested. The bottom ends of the contacts are designed to make contact with the test equipment board 4 (shown in Figs. 2 and 3).

The contacts are opened and closed by actuating plates 5 and 6 which are operated by rotating a cam 7. The cam 7 causes the plates 5 and 6 to move a specific distance in opposite directions, thereby closing the normally sprung open contacts 2 against the product pins 3.

Figs. 2 and 3 show, respectively, the contacts 2 open and closed. The movement of actuating plates 5 and 6 causes the opening and closing of contacts 2 from and to the pins 3.

The connector is a true zero insertion connector. No side thrust is required of the module and module pins 3 to actuate this connector. The contacts are made on opposite sides of each pin 3, thereby neutralizing the forces on the product. Both Kelvin and non-Kelvin connections can be made with the product, depending on the test requirements. The bottom ends of the preferred contacts are buckling beams 8, which permit or provide nonsoldered connections to the test equipment board 4. This provides quick and easy removal of the connector for maintenance purposes.

The replaceable contact subassemblies are made by chemically etched lead f...
