Integrated insulator

Abstract

The invention discloses an integrated insulator. The integrated insulator includes an insulator, a bolt, a spring seat, a contact spring and a pull bar, wherein the lower end of the bolt is a screw with an external thread, and the upper end of the bolt is a polygonal head; a first groove is formed in the polygonal head of the bolt; the lower end of the insulator is received in the first groove; the upper end surface of the insulator is provided with a second groove; the spring seat is fixed in the second groove; the spring seat is provided with a spring mounting hole; the contact spring is installed in the spring mounting hole, and the lower end of the contact spring is fixed at the bottom of the spring mounting hole; and movement of the lower end of the pull bar is limited in the spring mounting hole and is fixedly connected to the upper end of the contact spring. The integrated insulator fixes the contact spring and the pull bar by means of cooperation of the lock nut and the insulator, and satisfies the characteristic that the insulator is small in size. The axial positioning of the pull bar and the bolt is to utilize mutual cooperation between the pull bar, the spring and the spring seat, so as to satisfy the coaxiality of the pull bar and the bolt, and the number of parts and the complex machining processes of the parts are reduced.

Description

technical field [0001] The invention relates to an integrated insulator, which is mainly used for contactors. Background technique [0002] The insulator used in the existing contactor has a split structure, and the insulator, the contact spring, the connecting rod and the bolt are fixed to each other, resulting in a large structure, which cannot be used in existing small-volume products. There are a large number of processed parts of the components, the production process of the parts is complicated, the processing cycle is long, and the assembly process of the components is complicated, and more special fixtures are needed to complete the assembly of the overall components. Axis difference. Contents of the invention [0003] In order to overcome the above defects, the present invention provides an integrated insulator, which not only has a simple structure, reduces the number of parts, but also reduces the complicated processing technology of the parts. [0004] The te...
