ELECTRICAL CONNECTOR JACK ASSEMBLY FOR SIGNAL TRANSMISSION

摘要

A modular jack electrical connector assembly (2) suitable for conditioning the signals in unshielded twisted pair wires for use with network components is disclosed. The modular jack (2) comprises a conventional insulative housing (4) and an insert subassembly (6) including an insert molded front insert member (8) and a rear insert member (10). Contact terminals (12) for mating with a modular plug extend from the front insert member (8) and into the rear insert member (10). The rear insert member (10) also includes signal conditioning components such as common mode choke coils (38), filter circuits (40) and transformers (54) suitable for conditioning the twisted pair signals for use in applications such as for input to and output from IEEE 10 Base-T network components. The rear insert member includes an insert molded body (30) which stabilizes the position of the contact terminals (12) and leads (14) extending from the rear insert member (10) for attachment to external circuits, such as the external printed circuit board containing the interface processor for the specific application. The signal conditioning components can be mounted on a component printed circuit board (36) also encapsulated. Additional leads (50, 60, 70, 80) are connected to an exposed portion of the component printed circuit board to serve as ground and other connections. A shield (92) can also establish contact with the exposed portion of the component printed circuit board to establish a ground connection.
