YOKE CLAMP Russian patent published in 2013 - IPC H01R4/36 

FIELD: construction.

SUBSTANCE: in a yoke clamp with a profiled U-shaped yoke (23), comprising the first and second side sections (11a, 11b) and a link (12) that connects them, side sections (11a, 11b) comprise windows (13a, 13b) matching each other in the centre. The link (12) is equipped with a threaded hole (26) to receive a screw (27) and to press a conductor (14a) pulled through windows (13a, 13b). At least one of windows (13a, 13b) has a substantially rectangular frame (15). The first short segment (16) of the frame is located on the side facing the link (12). The second short segment (17) of the frame is located on the side facing the end (18) of the side section. Both short segments (16, 17) of the frame are connected with two long segments (19a, 19b) of the frame, which in direction of the link (12) are arranged substantially at the right angle to the first short segment (16). Both long segments (19a, 19b) of the frame inside the window (13a, 13b) in direction of the second segment (17) of the frame have a straight slant (33). To use action of edges between straight slants (33) and the screwed wire (14a), the material of the profiled U-shaped yoke (23) has thickness (21), which is less than the distance (22) between side sections (11a, 11b).

EFFECT: provision of reliable connection with simplification of design and assembly and limited number of parts.
