US 5,647,767 A · Electrical connector jack assembly for signal transmission

Abstract

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 used 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.
