Abstract
An electrical connector that detachably connects a cable having a metal sheath enclosing electrical conductors, to a second set of conductors. The connector is formed from a tubular, elongated housing that is separated into two sections. A first section is metallurgically joined to the sheath of the cable that it is connecting and the cable conductors are coupled to a corresponding number of electrically conductive pins in a second section of the housing to which the first section is then joined. A complementary connector is electrically joined in the same manner to a second cable to which the first cable is to be detachably connected.
Claims15
An electrical connector that detachably connects a cable having a metal sheath enclosing a first conductor, to a second conductor, comprising:
- a first elongated, tubular, metal housing section having a longitudinal portion with a diameter at a first end that is sized to closely receive and prepared to be metallurgically joined to the sheath of the cable carrying the first conductor;
- a second elongated, tubular, metal housing section having a first end which is sized to mate with the second end of the first housing section, the second end of the first housing section and the first end of the second housing section having abutting surfaces that are prepared to be mechanically or metallurgically joined, and said second housing section having a second end that is formed to be detachably connected to a mating second electrical connector;
- and
- an elongated, electrically conductive pin, supported by the second housing section, having a first end designed to electrically connect with the first conductor and a second end that is formed to electrically interface with a complimentary electrically conductive pin on a second electrical connector that is electrically connected to the second conductor.
A method of detachably connecting a first electrical cable having a metal sheath enclosing a first conductor to a second electrical cable for use in a hostile environment comprising:
- providing a first elongated, tubular, metal housing section having a longitudinal portion with a diameter at a first end that is sized to closely receive and prepared to be metallurgically joined to the sheath of the first cable carrying the first conductor;
- threading the first cable through the first end of the first elongated, tubular housing section;
- brazing the sheath of the first cable to the first end of the first elongated, tubular metal housing section;
- providing a second elongated, tubular, metal housing section having a first end which is sized to mate with the second end of the first housing section, the second end of the first housing section and the first end of the second housing section having abutting surfaces that are prepared to be mechanically or metallurgical joined, and said second housing section having a second end that is formed to be detachably connected to a mating second electrical connector, said second housing section supporting an elongated, electrical conductive pin having a first end designed to electrically connect with the first conductor and a second end that is formed to electrically interface with a complimentary electrically conductive pin on a second electrical connector that is electrically connected to the second conductor;
- connecting the first electrical conductor to the first end of the electrically conductive pin;
- and
- joining the second end of the first housing section to the first end of the second housing section.
