Anti-play terminal stud of hollow reactor

Abstract

The invention relates to an anti-play terminal stud of a hollow reactor. The terminal stud is arranged in a hollow reactor shell and is cylindrical; one end of the terminal stud is fixedly welded with a limiting block; a semicircular limiting groove which is matched with the limiting block is arranged in the hollow reactor shell. The anti-play terminal stud has a simple structure, and is reliable to use and firm in connection; one limiting block is welded on the stud; one semicircular limiting groove is drilled in the hollow reactor shell; the degree of freedom of rotation of the terminal stud is limited through a limiting principle of the limiting block and the limiting groove; then a circle of rubber seal ring is additionally arranged at the outer end of the terminal stud, so that the terminal stud is stabilized by increasing the friction force.

Description

technical field [0001] The invention relates to a connection bolt, in particular to a movement-proof connection bolt for an air-core reactor. Background technique [0002] Conventional air-core reactor wiring studs are purely cylindrical. After connecting with the air-core reactor shell, whenever the external wiring is performed, the wiring screw may be driven to rotate. After the internal lead is connected, it is often impossible to control and lock it. Therefore, the movement of the wiring screw may cause the internal lead wire to loosen, and it will fall off seriously, causing the equipment to fail to operate normally. If the output terminal falls off, metal parts falling into the coil will cause the coil to discharge or burn out, causing serious accidents. The impact cannot be ignored. Contents of the invention [0003] In order to solve the above problems, the present invention provides an air-core reactor with simple structure, reliable use and firm connection. [0...
