CLAMPING STRUCTURAL ELEMENT Russian patent published in 2012 - IPC H01R4/48 

FIELD: electricity.

SUBSTANCE: clamping structural element (1) has a dielectric body (2) and at least one springy clamping connecting element (3), which comprises a bent clamping spring (4) made of a spring steel sheet with a support tab (8) and a clamping tab (7) attached to each other by means of a spring arc (6), a current-conducting bus (5), inserted into the clamping tab (7) and adjacent to the support tab (8), and a channel (9) for wire insertion arranged in the dielectric body (2), stretching from a rear spring arc (6) of the clamping spring (4) along the support tab (8), at least to the current-conducting bus (5). A wall of the channel (9) formed from the dielectric body (2) breaks at a separate section, and the end of the current-conducting bus (5) adjoining the support tab (8) stretches as inclined to the support tab (8) and forms a funnel of the channel (9) for wire insertion. The support tab (8) of the clamping spring (4) in a broken section of the dielectric body (2) together with the current-conducting bus (5) forms a wall of the channel (9) for wire insertion.

EFFECT: invention provides for optimal electric contact and prevents against wire pulling from the clamping connecting element without actuation of the clamping spring.
