Abstract
A multiple layer conductor pin for a harsh environment connector or penetrator has a conductive shaft, an outer layer of non-conductive, insulating material extending along at least part of the length of the shaft, and an intermediate layer of conductive or semi-conductive material sandwiched between the outer layer and conductive shaft and bonded substantially void-free to the outer insulating layer.
Claims59
A multiple layer conductor pin for a harsh environment connector or penetrator, comprising:
- a conductive shaft having first and second ends;
- an outer layer of non-conductive, insulating material extending along at least part of the length of the pin;
- and
- an intermediate layer of conductive or semi-conductive material sandwiched between the outer layer and conductive shaft and bonded substantially void-free to the outer insulating layer.
An electrical plug unit for a harsh environment connector, comprising:
- a plug module of conductive material having a through bore and front and rear ends;
- a conductor pin extending through the bore and having a first end portion projecting out of the front end of the module for engagement in a forward end opening of a mating receptacle module;
- and
- the conductor pin comprising a conductive shaft having forward and rear ends, an outer layer of non-conductive, insulating material extending along at least part of the length of the shaft including part of the first end portion of the pin, the insulating layer terminating short of the forward end of the shaft to define a conductive tip, and an intermediate layer of conductive or semi-conductive material sandwiched between the outer layer and conductive shaft along the entire length of the outer layer and bonded substantially void-free to the outer insulating layer.
An electrical penetrator pin assembly for use in harsh environments, comprising:
- a pre-formed outer tube of non-conductive, insulating material having a through bore and opposite first and second ends;
- a conductive shaft extending through the tube and having opposite first and second ends extending outwardly from opposite ends of the tube;
- and
- an intermediate layer of conductive or semi-conductive material between the shaft and outer tube, the intermediate layer extending at least between the first and second ends of the tube and being bonded substantially void free to the tube through bore.
A method of making a multiple layer conductor pin for a harsh environment electrical connector or penetrator, comprising:
- applying an intermediate layer of conductive or semi-conductive material to the outer surface of a conductive shaft;
- and
- over molding an insulating layer of insulating polymer material over the intermediate layer, the insulating layer being of a material compatible with the material of the intermediate layer such that a bond is formed between the insulating layer and intermediate layer;
- whereby the bond between the insulating layer and coating layer is substantially void-free.
