Abstract
An electrical connector is used in a pumping oil well to deliver electrical power to a submersible pump. The connector includes a rigid housing having two bearing assemblies allowing relative rotational movement between parts of the housing to allow the upper housing end to threadably connect to a feed through socket and to allow the lower housing end to be rotated to axially compress a resilient dielectric conductor seal body between a pair of rigid dielectric alignment bodies.
Claims20
An electrical connector for connecting a cable having multiple insulated conductors to a feed through socket, comprising
- an elongate housing made of rigid material and having an axis, the housing having an upstream end and a downstream end;
- means on the downstream end of the housing for gripping the exterior surface of the cable and immobilizing the cable;
- means at the upstream end of the housing for securely connecting the electrical connector to the feed through socket;
- a contactor assembly comprising
- a contactor support body made of a dielectric material substantially filling the upstream end of the housing;
- an electrically conductive contactor tube, for each of the conductors, supported within the body, the tubes being aligned in an upstream-downstream direction and having
- a downstream opening for receiving one of the conductors of the cable, and
- an upstream electrical contactor portion for mating with a corresponding contactor in the feed through socket;
- a pair of spaced rigid dielectric alignment bodies in the housing providing aligned pairs of passages for each of the insulated conductors, a first alignment body being juxtaposed to the contactor support body;
- a resilient dielectric conductor seal body between the alignment bodies having a passage aligned with each of the aligned pairs of passages of the alignment bodies for receiving the insulated conductors therethrough;
- and
- means for axially moving the rigid alignment bodies toward each other for compressing the resilient conductor seal body against the insulated conductors.
In combination, an electrical connector, a feed through socket and a cable having multiple insulated conductors including a board end having a conductor pin thereon, a dielectric jacket around the conductors terminating subtantially short of the bared end and an armor sheath around the jacket terminating substantially short of the dielectric jacket, comprising
- an elongate housing made of rigid material and axially aligned with the cable, the housing having an upstream end connected to the socket and a downstream end adjacent the cable;
- means on the downstream end of the housing gripping the exterior surface of the dielectric jacket and immobilizing the cable;
- a contactor assembly comprising
- a contactor support body made of a dielectric material substantially filing the upstream end of the housing;
- an electrically conductive contactor tube, for each of the conductors, supported within the body, the tubes being aligned in an upstream-downstream direction and having
- a downstream opening receiving the conductor pin of the conductor, and
- an upstream electrical contactor portion for mating with a corresponding contactor in the feed through socket;
- a pair of spaced rigid dielectric alignment bodies providing a plurality of aligned pairs of passages, each passage pair receiving one of the insulated conductors, one of the alignment bodies abutting the contactor support body;
- a resilient dielectric conductor seal body between the alignment bodies having a passage aligned with each of the aligned pairs of passages of the alignment bodies and receiving one of the insulated conductors;
- and
- means for axially moving the rigid alignment bodies toward each other and compressing the resilient conductor seal body against the insulated conductors.
