  • Patent number: 4968262
    Abstract: A connection device (10) comprising a body (12, 14), which has at least one outlet hole (30), one insertion part (16) as well as a rotatable and axially displaceable contact and locking bar (18) and is designed to be placed in a substantially C-shaped current rail having a logitudinal hole. The contact and locking bar has three phase conductor pins and a neutral conductor pin designed to cooperate with phase and neutral conductors disposed beside the longitudinal hole of the current rail. The contact and locking bar (18) is pivoted and axially displaced by means of an operating arm (38) provided with an eccentric. The operating arm is retained in a pulled down fastened position by means of a sliding lid (32), which cooperates with a built-in switch (34) of the connection device.

  • Patent number: 4881907
    Abstract: Conductor strip (1) for electrical and telecommunication conductors with one or several through metallic conductors (9), which are arranged to be connected up at any selected position, and which are arranged on or in an electrically non-conductive strip base (5). The metallic conductor or conductors (9) is or are embedded in a through electrically conductive string or cord (8) of plastic material. Because of the inherent resiliency of the material and/or the springiness of the strip structure, the conductor strip (1) is automatically lockable by expansion or outward springing of the strip, whereat the free ends of the strip (1) are caused to engage behind projections (4) of an installation channel (3).

  • Patent number: 4494808
    Abstract: Electrical current rail 1, which may function as collector rail for power distribution, houses phase conductors 35, 36 and zero-conductor 37, with which adaptor 2 is intended to come into contact via plugs (86, 98), which are connected to a respective phase conductor plug and zero-conductor plug (not shown) intended to provide electrical connection with said adapter 2. Said phase conductors 35, 36 are provided in the interior space 16 behind the front 7, 8 of the rail and are accessible only in a direction from the inside of the rear side 4 of the rail. The front 7, 8 is divided by an opening 11 for reception of an insertion part 49, 50 of the adapter 2 provided with a contact beam 78, which is both pivotable and movable backwards and forwards into contact with said phase conductors and out of contact with the same by means, e.g. screw 69, accessible on the front of the adapter 2.
