COUPLING BOX FOR CONDUCTOR RAIL Russian patent published in 2017 - IPC H01R25/14 

FIELD: electricity.

SUBSTANCE: coupling box (1) for conductor rail (2) is arranged symmetrically relatively to the middle transverse plane (for example, 13) and includes contacts for contacting with conductor rail wire(2), as well as the mechanical guide parts and thrust parts, by means of which the coupling box (1) adapted to be inserted into the end face side of the conductor rail (2) with a stroke limitation. Wherein the contacts (14-17) are respectively arranged with the possibility of spring displacement in the coupling box housing (1) part, transversely to its longitudinal axis, the L-shaped contact strips (23), having one laterally projecting on the one side and one - on the other side from the middle thrust wall (13) of the housing, forming the middle transverse plane or performed in it, the contact section (24) at the first L-shaped arm (25), adjacent by the boundary edge (26) of the second arm (27) indirectly through the flat strip (28) from the sheet steel to the housing wall of the insulating material. On the strips (28) made of the spring sheet steel the V-shaped bent spring (29) is moulded and bent at the right angle from the strip (28) from the sheet steel, it has the middle part (30), the arms ends of which are spring joined to the outer surface of the second arm (27) of the contact strip (23) opposite to the projecting contact sections (24) of the first arm (25).

EFFECT: installation simplification and reduction of the wear and tear in the spring contacts area.
