Abstract

The invention discloses an expansion valve coil, and relates to the technical field of coils. The expansion valve coil comprises a joint assembly, a box body and a box cover, the box body is internally provided with a cylindrical wound coil, the joint assembly comprises a pin, the side surface of the box body is provided with a groove matched with the shape of the joint assembly, the groove is provided with a hole for the pin to pass through, the hole is located in the axial direction of the coil, the box body and the box cover are matched through a step structure, the box cover is located on the axial section of the coil, glue is injected into the box body, and a positioning groove matched with the box body is formed in the surface of the connector assembly. Compared with the prior art, the expansion valve coil has the following beneficial effects that: the box body and the box cover are subjected to injection molding press fit along the axial direction of the coil, the pin structure of the joint assembly is inserted along the axial direction of the coil, one-time press fit injection molding can be realized after the position is adjusted, the assembly efficiency is improved, the reject ratio of the joint assembly is low, and the structural strength is better.

Description

technical field [0001] The invention relates to the technical field of coils, in particular to an expansion valve coil. Background technique [0002] The expansion valve coil is an automatic basic component used to control the fluid. It adapts to the development requirements of mechatronics. It has excellent characteristics that cannot be compared with thermal expansion valves, and provides superior conditions for intelligent control. The expansion valve is a promising self-control component, and the expansion valve coil has become an indispensable part of the electrical components. The basic purpose of the expansion valve is the same, and the structure is various, but in terms of performance, there is a large difference. The existing expansion valve coil is divided into two injection moldings. After the injection molding, the joint assembly needs to be injected again with the coil body to complete the finished product. The joint assembly needs to be injected and pressed tw...
