ELECTRICAL CONTACT COUPLING FOR TRACKED VEHICLE Russian patent published in 2014 - IPC B61G5/10 H01R13/52 

FIELD: electricity.

SUBSTANCE: invention is related to electrical contact coupling for tracked vehicles, in particular, for railway vehicles. The contact coupling consists of a body (1), a protective hinged cover (4), and a sealing gasket (3). In the body (1) there is an opening (2) made at end surface of the body. The protective hinged cover is pinned to the body (1) so that it can be rotated in regard to the fixed axis of rotation. The sealing gasket has the upper sealing area (3a) parallel to the axis of rotation and the lower sealing area (3b) continued in parallel to the axis of rotation. The section of contact area interacting with the upper sealing area (3a) in the closed position of the cover is made as sealing surface (5a) and oriented perpendicular to the end surface. The section of contact area interacting with the lower sealing area (3b) in the closed position of the cover is made as sealing surface (5b) and oriented in parallel to the end surface.

EFFECT: improvement of sealing.
