Abstract

The invention discloses a clamping device used based on a movable contact group. The clamping device comprises a movable contact seat, the top of the movable contact seat is movably connected with a movable contact column, the bottom end of the movable contact column penetrates through the top of the movable contact seat and extends to an inner cavity of the movable contact seat, the inner cavity of the movable contact seat is provided with an adaptive groove which is movably connected with the surface of the movable contact column, and an inner cavity of the adaptive groove is provided with a spring groove. The invention relates to the technical field of movable contact groups. According to the clamping device used based on the movable contact group, a movable contact column is inserted into an adaptive groove, a connecting groove in the bottom is adaptive to a connecting column, clamping is completed, at the moment, a clamping block abuts against the surface of the movable contact column, a top spring is compressed to retract into a spring groove, then the movable contact column is rotated, and the surface of the clamping block makes contact with the surface of a clamping groove; and pushed by a top spring, the clamping block is clamped in the clamping groove to fix the connecting column, so that the connecting column can be quickly fixed, and the connecting column is very convenient to take out and mount.

Description

technical field [0001] The invention relates to the technical field of moving contact groups, in particular to a clamping device based on moving contact groups. Background technique [0002] The dynamic and static contact groups are used to control the position of the switch and realize the electrical interlocking of the railway point machine. The dynamic and static contact groups are extremely important signal components. The moving contact group, the static contact fixedly installed on the contact seat, and the dust-proof arc extinguishing cover covering the dynamic and static contact, when the switch is switched, the moving contact bracket in the switch machine will drive the moving contact group to contact with the static contact assembly, To further realize the signal transmission of electrical equipment, at present, the existing moving contact group includes a column made of phenolic glass fiber with three power supply rings installed, and the moving contact ring is in...
