ABSTRACT:
An electrical connection across a peripheral surface through a sealed enclosure (34A) in a radial plane between a tubing hanger (5) and a surrounding support member (3). The connection involves a coupling element (17) in the tubing hanger and an electrical contact supporting shuttle (20) which can reciprocate from a position wholly within the support member, across the interface and into electrical connection with the coupling element, without producing any movement of a cable (9,10,11,15) leading into a sealed enclosure within the support. In certain embodiments (FIGS. 3-7), the shuttle (20) is driven by threaded engagement with a rotatable drive sleeve (30) and includes a sleeve (21) that is reciprocated over a stationary power core (22, 22'). The shuttle is also filled with a dielectric gel (26) contained within a flexible bladder (25). A sensor contact (35) can be used to indicate full retraction of the shuttle (FIG. 5).
