Abstract

A static contact seat comprises a static contact piece arranged in a cavity and a pressure piece arranged at the front end of the cavity and arranged on the outer side of the static contact piece, thepressure piece is an elastic piece, the front end of the elastic piece is connected with an elastic segment overlapped with the front end of the elastic piece through a curved surface, and the elastic segment is pressed between the elastic piece and the static contact piece. The rear end of the elastic piece is an annular surface, and is fixed on the wiring terminal bolt together with the annularsurface at the rear end of the static contact piece. The clamping force can be effectively enhanced through the bent elastic segment with potential storage elasticity at the front end, and meanwhile,the problem of insufficient force provided by a side spring in the prior art is effectively avoided; and the wire is flexibly connected, so that the defect of creepage caused by connecting the wire with the bottom end of the wiring terminal bolt in the prior art is overcome.

Description

technical field [0001] The invention relates to a constant-voltage static contact seat for controlling the action of an electric switch machine, indicating the position and state of a turnout, and realizing electromechanical interlocking. Background technique [0002] At present, the electromechanical interlocking, especially in the process of track signal operation, is a kind of signal in the opening direction that passes or turns around the vehicle operation, which is realized by the actions of the static contact group and the matching moving contact group on the electric switch machine. of. For this reason, the dynamic and static contact not only has higher requirements on structural performance and service life. At the same time, it is suitable for safe use in various harsh environments, so as to ensure the safe operation of the railway. The static contact group can be divided into two types in the prior art: one is in a static state, using the elastic force of the cont...
