ABSTRACT:
A connector 10 is disclosed which is suited for use in effecting an electrical connection between separate conductor bundles 12, 16 in adjacent sections of a threadably sectioned conduit. The connector 10 is especially well suited for use in providing electrical continuity across a tool joint in a drill string. The connector 10 has first and second portions 20, 22 each adapted for placement in a corresponding connection portion of two connectable lengths of conduit. The first and second portions 20, 22 form a pin and box connection. Corresponding contacts 46, 80 on the first and second portions 20, 22 assume a conductive relationship in response to connection of the conduit. The contacts 46, 80 of each connector portion 20, 22 are radially symmetric about the axis of the conduit and are axially displaced one from the other. The contacts 46, 80 within the assembled connector 10 are isolated from the conduit environment. Apparatus is provided for maintaining a dielectric fluid in the region surrounding the contacts 46, 80 to ensure electrical insulation of the connector 10.
