AUTOMATIC WINIDING DEVICE FOR THREE-CORE CABLES

摘要

The invention represents an application of the winding mechanism for winding three-core supply cables for devices, where it is necessary also to provide an earthing cable thus ensuring user safety in the case of a short-circuit. For safety reasons the earthing of the winding device is provided across two earth-links. The sliding earth link runs across the spring (4) cage where the earthing conductor from the cable (10) is attached to by a faston clamp (9) along with spring washer (6), pipe-like rivet (7), and contact washer (12) against the contact joint (11), which is by a faston clamp (14) attached to the internal earth conductor (13). The permanent earth link runs across the driving spring (5), which is inserted in cage (4) and the contact joint (11), which is on one side riveted to the driving spring by a rivet (15), while on the other side it is connected by a faston spring (14) to the internal earth link (13). In the cylinder-shaped enclosure interface (1a) there is a safety tube (8) inserted into the centre, which in case that the plastic enclosure turns soft or breaks for any reason, it ensures an electrical earth link between the spring cage (4) and the earth contact joint (11)
