FASTENING DEVICE Russian patent published in 2024 - IPC H02G3/12 

FIELD: electricity.

SUBSTANCE: invention relates to fasteners for fixing electrical installation devices. For this purpose, the fastening device for fixing the electrical installation device includes a main body with a base surface and a grip, which is held on the main body by a screw screwed into a nut, and by means of screw rotation can be rotated from retracted position to unclamped position. At that, the grip is U-shaped and has two arms, which are connected to each other by means of a bridge, and to turn from retracted position into unclamped position, force is applied between nut and bridge through bevelled surface made between nut and bridge. When the grip is turned, the nut turns relative to the main body together with the screw, but independently of the grip, and the main body has a support surface for the bridge, which is bent at an angle. At the same time, the support surface has the first support surface, which passes parallel to the base surface, as well as the second support surface, which is inclined relative to the base surface.

EFFECT: achieving maximum unclamping position with minimized occupied area inside the main housing of the device while the nut, when the grip is turned, can turn relative to the main housing together with the screw, but independently of the grip.
