Problems solved by technology

The defect of the contactor assembly structure is:
[0003] 1. Since there is no fixation between the coil bobbin and the body, the coil bobbin is easy to fall during automatic assembly, and it is difficult to realize automatic assembly
[0004] 2. The body and the base are locked by screws, and the locking of the screws needs to be done manually, which makes it difficult to realize automatic assembly
[0005] 3. Use screws to lock the body and the base, increasing the cost of using screws, making the cost relatively high

Abstract

The invention discloses a buckle type connection structure of a contactor. The buckle type connection structure comprises a shell and a coil frame. Containing cavities used for mounting contacts are formed in the shell and are separated by side plates. The buckle type connection structure is characterized in that the coil frame and the shell are connected through a first buckle, the first buckle protrudes and extends on the center side plate of the shell to be a buckle, the center side plate is on the axial center line of the shell, correspondingly, a limiting groove which is matched with the center side plate is formed on the coil frame, the coil frame is inserted into the shell, the center side plate passes through the limiting groove, the center side plate buckle is hooked on the coil frame at one side of the limiting groove, and the coil frame and the shell are connected. According to the buckle type connection structure, the contactor is suitable for automatic assembly, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of contactor assembly, in particular to a snap-fit ​​connection structure of a contactor. Background technique [0002] In the prior art, when the contactor is assembled, the coil bobbin is usually placed in the body first. At this time, the coil bobbin and the body are not fixed, and the coil bobbin is only placed in the cavity formed by the body, and then the body and the body The base is assembled by screw locking. The defect of the contactor assembly structure is: [0003] First, because there is no fixation between the coil bobbin and the body, the coil bobbin is easy to fall during automatic assembly, making it difficult to realize automatic assembly. [0004] Second, the body and the base are locked by screws, and the locking of the screws needs to be done manually, which makes it difficult to realize automatic assembly. [0005] Third, the use of screws to lock the body and the base increases the ...
