The electrical connector (figure 1) contains the socket 1 and the plug 2. The socket is made in the form of a dielectric, for example, plastic parts 3 with built-in electrical contacts 4 and the plastic cover 5 (Fig.2-4). In the cover still embedded ferromagnetic plate 6. The cap has a hole 7 for access to the electrical contacts and openings 8 for attaching mounting screws (not shown) to the plastic parts. Plug (figure 5 and 6) with the input end of the electric wire 9 is made in the form of a plastic body 10 with a pair of pins 11. In case the plug is embedded core 12 and a coil 13, performs the function of an electromagnet.
