Electrical connection device for the domestic communication system

摘要

The arrangement incorporates optical waveguides (32) coupled to the photoemitter (S) and photoreceiver (E) of a bus coupler (BA) and extending to the region of the frontal plane of a supporting frame (7) under a cover (17). Additional lightguides (LW1,LW2) are included with the three-phase wires (L1-L3,N etc.) in a movable cable (6) leading to external equipment. The coupler carries a fixed plug (22) for connection via a socket (21) to the electric bus (20). The optical waveguides have flexible extensions (35,36) to free connector terminals (37) with optical windows (27,28).
