Electrical connection- and junction box e.g. solar socket, for use in building roof, has strain-relief unit that comes into position, in which it exerts clamping force on inserted conductor, where force acts as strain relief for conductor

摘要

The box has an electrical conductor (3) that acts on a pre-tensioning unit (6) during insertion of the conductor such that the pre-tensioning of a strain-relief unit (4) is loosened at an insertion depth of the conductor. The strain-relief unit comes into a position, in which it exerts a clamping force on the inserted conductor, where the clamping force acts as strain relief for the conductor.
