Abstract: An electrical connector assembly has socket and plug connectors. Each connector comprises a block of dielectric plastic in which are tapered cavities containing pyramidal modules which have two sections forming a casing enclosing an electrical contact. The modules of the socket connector contain spring contacts located at socket openings in the module casings. Each module of the plug connector contains a rigid bar which extends as a prong out of the smaller end of each plug module to fit into a socket at the smaller end of a socket module in the socket connector. Other ends of the contacts in all modules extend out of larger ends of the modules and carry screws for attaching circuit wires. The dielectric casings of all modules may be thermally bonded to the walls of the cavities in the dielectric plastic blocks.
