Circuit board and socket assembly

Abstract

An interconnect device and electrical signal filtering connector is disclosed that does not require soldering. The interconnect device is an electrical contact that has a proximate or forward end with a cavity for receiving an electrical conductor of a first plug, and a distal or rear end, also called a tail, formed with a circumferentially-arranged undercut that engages the ends of one or more electrically conducting flanges that extend radially inward in a contact receptacle of a printed circuit board. The connector can be a male plug or female receptacle, including a receptacle with front and rear shells and an insert slidably engaged inside the shells, the receptacle adaptable for receiving a round, 14-conductor plug. The printed circuit board assembly includes a printed circuit board with one or more contact receptacles.

Description

technical field [0001] The present invention generally relates to electrical connectors. In particular, the present invention relates to a method and system for interconnecting a printed circuit board to the rear of an electrical socket or plug. Background technique [0002] The present method and system for connecting a printed circuit board to the rear of an electrical receptacle and plug connector includes soldering the connector contact tails to the circuit board. The purpose of the welding operation is to provide electrical and mechanical connections. In some cases, the heat generated by the soldering process may adversely affect the connector and printed circuit board. As a result, the electrical performance of the interconnect may be irreparably damaged, or at least significantly degraded. Of course, performance degradation must be avoided in electronic devices used in avionics and other sensitive systems, especially where stringent specifications must be met. [...

AI Technical Summary

Problems solved by technology

[0008] The problem with the pin contact disclosed by Bright et al. is to achieve electrical continuity at the very far end of the contact, which is not feasible if it is used to electrically connect a printed circuit board

[0012] The problem with the contact pin disclosed by Birnholz is that the rigid metal barb of the contact exerts force on the plastic hole during insertion of the contact causing it to separate

This will create internal stresses inside the PCB near the vias, compromising the performance of the device

Also, the contact through-hole receiver forms a rigid connection with the contact, which is disadvantageous in some applications as previously described

[0013] None of the various solutions for making solderless interconnections described in the above cited patents found an overall satisfactory solution
