FIELD: mining.
SUBSTANCE: proposed the electrical connector unit, installed in the borehole and containing: the upper longitudinal element with the electrical conductor, the lower longitudinal element, containing the electrical conductor, the telescopic electrically conductive unit and the electrical contact element, disposed around the end part of the lower longitudinal element electrical conductor and configured with ability of mobile contact to it. In this case, the telescopic electrically conductive unit contains the longitudinal receiving part at the end part of the upper longitudinal element electrical conductor. The longitudinal receiving part is located around the end part of the electrical conductor of the lower longitudinal element. The indicated contact element is configured with ability of mobile contact to the inner surface of the longitudinal receiving part of the upper longitudinal member.
EFFECT: provision of electricity or signals reliable transmission with possible changes of the cable length.
