Lock for multipole electric socket units - has enlarged longitudinal holes for housing retaining pins provided with open slots

摘要

Lock for multipole electric socket units comprises a housing in two halves held together by a U-shaped stirrup and four pins, with at least two pins on each half of the housing. To reduce the required number of parts for the lock stirrup longitudinal holes for the retaining pins are provided with an open slot running from the stirrup catch to the end of the side-face of the stirrup, each slot having a width somewhat greater than that of the retaining pins. In this way, the retaining pin holes are enlarged. V-shaped wire springs are hinge-mounted, in the vicinity of the upper gripping jaw or section of the lock, on the inner side of each side-face of the stirrup and are provided with an S-shaped hook-piece on their corresponding free ends.
