Abstract

This connector, as shown in the figure, consists of individual double-contact assemblies 2 which are inserted in and retained in rectangular openings in a housing. The upper formed ends of the contacts 2 are designed to make contact with the pins 3 of the product to be tested. The bottom formed ends of the contacts 5 are designed to make contact with pins 4 in the test equipment printed-circuit board, not shown.

Zero Insertion Connector with Individually Replaceable Contacts

This connector, as shown in the figure, consists of individual double-contact assemblies 2 which are inserted in and retained in rectangular openings in a housing. The upper formed ends of the contacts 2 are designed to make contact with the pins 3 of the product to be tested. The bottom formed ends of the contacts 5 are designed to make contact with pins 4 in the test equipment printed-circuit board, not shown.

The upper and lower contacts 2 and 5 are opened and closed by actuating plates 6 and 7, which are operated by rotating cams 8. The cams 8 cause the plates 6 and 7 to move specific distances in opposite directions, thereby closing the normally sprung open contacts 2 and 5 against the product pins 3 and also against the test equipment printed-circuit board pins 4, respectively. The lower contacts 5 are actuated only when mounting or removing the connector from the test equipment.

This is a true zero insertion connector. No side thrust is required on the module and module pins 4 to actuate the contacts. The contacts are made against opposite sides of each pin 3, thereby neutralizing the forces on the product. The metal actuating plates 6, 7 and metal housing plates provide shielding for AC test requirements. The very precise actuating plates are made from steel. The portions of the actuators 6, 7 that touch the contacts 2, 5 are inserts made of insulating material. All other exposed areas of the...
