Abstract: Provided are a framework, a framework assembly, a coil assembly and an electronic expansion valve. The framework includes a framework body, a connecting part and a pin socket, wherein a first end of the connecting part is arranged on a peripheral surface of the framework body, the pin socket is arranged at a second end of the connecting part away from the framework body, the framework further includes at least one support part, and the at least one support part is arranged on the connecting part, which can solve the problem of the poor waterproof effect of a coil assembly.

Abstract: An expansion valve coil structure, a method for preparing an expansion valve coil structure and an expansion valve are provided. The expansion valve coil structure includes a stator housing and an electromagnetic pole plate, the stator housing and the electromagnetic pole plate are disposed opposite to each other. The stator housing and the electromagnetic pole plate are both provided with a plurality of processed exposed surfaces. A surface of the stator housing and a surface of the electromagnetic pole plate are covered with a first antirust layer. Each of the plurality of processed exposed surfaces is covered with a second antirust layer The expansion valve includes the expansion valve coil structure.

Abstract: Disclosed is an expansion valve coil assembly, comprising a coil unit and a housing, wherein the coil unit is provided with a mounting platform, the mounting platform is provided, in a partially protruding manner, with a connecting part, and the housing is sheathed over the connecting part and is fixedly connected to the mounting platform; and a side wall of the connecting part has a concave-convex structure, and the space between an inner side of the housing and the connecting part is filled with a sealing material.
