WIRE-CHASE SYSTEM FOR ELECTRIC WIRES

A casing system for laying electric supply conductors and, if desired, signal conductors along the outer surfaces of walls of buildings comprises elongated casing sections (103) having longitudinal cavities (113, 115) for accommodating at least two supply conductors (117). The system also comprises end sections (101) and corner sections (201, 202), as well as sliding cover sections (102) for interconnecting these and the casing sections (103) to form a continuous casing structure covering any given length of wall without cutting or other adaptation of any of the sections. Distributed over its length each casing section (103) has access modules (X, Y, Z), where access can be established to the supply conductors (117) by means of connectors (145) having forked contact legs (151) that can be pushed through access slots (132) in the front wall (110) of the section into engagement with contact pieces (124) clamped on the conductors (117). In each access module, the contact pieces (124) are held in position behind the access slots (132) by means of a front holder (126) and a rear holder (127), which penetrate into the cavities (113, 115) from the front and rear side of the section (103) and are mutually interlocked. The rear holder (127) is constructed for attachment to a wall of a building and thereby serves to suspend the supply conductors (117) directly from the wall.
