Abstract
An electrical feedthrough includes a connector body made of a metallic material, at least one contact pin inserted through a cavity in the connector body, and an insulating body made of a thermoplastic material formed between the connector body and the contact pin so as to provide a hermetic seal between the connector body and the contact pin.
Claims20
An electrical feedthrough, comprising:
- a connector body made of a metallic material, the connector body comprising a mounting flange;
- at least one contact pin inserted through a cavity in the connector body and through a hole in the mounting flange, the cavity and the hole each having a transverse dimension generally parallel to the face of the mounting flange, the transverse dimension of the hole, being less than that of the cavity;
- and
- an insulating body made of a thermoplastic material formed between the connector body and the contact pin, the insulating body molded over a portion of the connector body and the contact pin and providing a hermetic seal between the connector body and the contact pin;
- and
- wherein an outer surface of the connector body in contact with the insulating body includes an interlocking structure.

An electrical feedthrough, comprising:
- a connector body made of a weldable metallic material, the connector body comprising a welding flange;
- at least one contact pin inserted through a cavity in the connector body and through a hole in the welding flange, the cavity and the hole each having a transverse dimension generally parallel to the face of the welding flange, the transverse dimension of the hole being less than that of the cavity;
- and
- an insulating body made of a thermoplastic material formed between the connector body and the contact pin, the insulating body molded over a portion of the connector body and the contact pin and providing a hermetic seal between the connector body and the contact pin;
- and
- wherein an outer surface of the connector body in contact with the insulating body includes an interlocking structure.

A bulkhead electrical connection, comprising:
- a bulkhead made of a weldable material;
- a connector body made of a weldable material;
- a weld formed between the bulkhead and the connector body at a face of the bulkhead;
- at least one contact pin inserted through a cavity in the connector body and through a hole in the connector body, the cavity and the hole each having a transverse dimension generally parallel to the face of the bulkhead, the transverse dimension of the hole being less than that of the cavity;
- and
- an insulating body made of a thermoplastic material formed between the connector body and the contact pin, the insulating body providing a hermetic seal between the connector body and the pin;
- and
- wherein an outer surface of the connector body in contact with the insulating body includes an interlocking structure.
