Abstract

These contacts are for making connections to conductive pins of circuit modules under test. Conductive pin 10 is inserted into the socket. Cam plate 12 is then lifted to bring contacts 14 and 16 together, to contact pin 10. Contacts 14 and 16 are insulated from each other by insulating material 18. Support is provided by plastic member 20. An AC test can now be performed where contact 14 Provides the input signal to pin 10 while contact 16 senses the response. In the alternative, contact 16 is replaced by contact 17 which is coated with insulation and partially surrounds pin 10. Contact 17 is grounded to provide an electrical shield as in a coaxial configuration.
