Abstract: A cradle connector for a radio-telephone base station has a plurality of terminals mounted in insulative housings the terminal interconnected by a shorting bar inmoulded to the housing. The terminals have spring section and contacts that are depressible against action of the spring to allow relatively large tolerances in the positioning of the telephone with respect to the base station. The contacts have extensions that abut against the shorting bar when the connector is disconnected, whereby one of the terminals is connected to ground so that electrostatic discharges do not damage the base station circuitry. Certain extensions can be removed for some of the terminals if such terminals should not be grounded (e.g. power terminals). The shorting bar could be made of wire that interconnects a plurality of housings during manufacturing and handling for reducing the cost thereof. The cradle connector is thus compact, cost-effective and protected against electrostatic discharge.

Abstract: Connectors formed from long strips of pin headers, which are cut to a length equal to the desired number of connector positions. A pre-molded shroud is then press fit to each end of the cut pin header.
