In-jack shunt connections and methods therefor

Abstract

Devices and methods by which an effective shunt-type electrical connection between the telephone company lines and subscriber wiring can be established and maintained within a line module. Line modules are described having a jack assemblies with improved arrangements for establishing connections between telco and bridging contacts. In one construction, two contacts are selectively moveable along a pair of channels to be brought into contact with fixed contacts to form an electrical connection between the telephone company and subscriber wiring. In an alternative construction, the fixed contacts are replaced with a contact plate formed of conductive plating. In other aspects, a plug member can be inserted into the jack receptacle to close the tip and ring contacts to create a shunt connection when the cover of the module is closed onto the base. The plug member can be made entirely from non-conductive material. Additionally, when the cover is closed, the two moveable contacts are maintained a suitable distance from one another, to reduce the possibility of arcing.
