Terminal blocks for printed circuit boards

摘要

A screwless terminal block and insulation displacement connector device includes a housing and slide slidably engaged in the housing, the device operable to receive a lead wire having lead wire conductors and an insulation layer, and to further receive a conductive connector. Movement of the slide to a closed position with a lead wire inserted in the device causes the lead wire to contact sharp connector edges, which, with continued downward force, cut the insulation layer. Continued downward force, to full closure of the device, forces lead wire conductors into compressed multiple electrical contact with the connector.

主权项

1. A screwless terminal block and insulation displacement connector device for a printed circuit board (PCB) comprising a housing having a channel and a slide slidably engaged in the channel, the slide operable to move in the channel between an open and closed position, the housing comprising a first opening formed in a first side thereof configured to receive a lead wire, a second opening formed in a second side thereof configured to receive a conductive connector extending from a PCB, a detent configured to contact the slide for permitting a locking engagement of the housing and slide in the closed position, and a third opening formed in a third side configured to receive a disconnecting tool, the slide comprising a locking element comprising a detent engaging surface and a pressure receiving surface, a disconnecting tool guide substantially axially aligned with the third opening and a lead wire guide configured to be substantially axially aligned with the opening formed in the first side of the housing, the slide further comprising a connector slot configured to receive a conductive connector receivable in the second opening of the housing, wherein the conductive connector comprises a lead wire receiving opening configured to be substantially axially aligned with the lead wire guide and the first opening of the housing, wherein the device in the open position is configured to receive a lead wire and in the closed position is configured to form an electrical connection between the lead wire and a conductive connector, wherein movement of the slide from a position distal the PCB toward the PCB is operable to move a lead wire positioned in the lead wire guide and the lead wire receiving opening of the conductive connector toward the PCB to form an electrical connection between the lead wire and the conductive connector.
