Further, be electrically connected with splicing ear on the said controller line plate, be provided with in the said connecting body with electromagnetic coil is electrically connected and be connected slot, said splicing ear with is connected slot and cooperates grafting realization controller line plate to be electrically connected with electromagnetic coil.

Further, said connecting body is provided with the clamping cover, and said connection slot is located in the clamping cover, and said controller housing is provided with the buckling groove that cooperates with the clamping cover, and sealing compound has all been irritated in controller housing inside and clamping cover inside.Guarantee the reliability and the sealing of connection.

Further, the bottom of said buckling groove is provided with the annular groove that cooperates with the end of clamping cover.Further strengthening connection body the two is connected with controller housing reliable with stablize, leak when preventing to pour into sealing compound simultaneously.

Further, the inner bottom surface of said connection slot equals on the splicing ear end face with the inner bottom surface applying that is connected slot to the distance between the inner bottom surface of annular groove to the distance between the end face of clamping cover.When satisfying installation requirement, the reliability and stability that strengthening connection body is connected with controller housing.

Further, be provided with the position shelf of terminal one end that is located by connecting in the said controller housing, said position shelf is provided with the locating slot of setting splicing ear, is provided with the positioning boss of the terminal the other end that is located by connecting in the said clamping cover.Because splicing ear is to realize being electrically connected through inserting mode with being connected slot; Therefore reliable and stable after requiring both to peg graft; So splicing ear is done further location, help splicing ear and the reliable electrical connection that is connected slot, can also prevent that splicing ear from teetertottering when mounted.

Further, have an assemblage gap between the inwall of said position shelf and controller housing at least, the minimum width of said assemblage gap is greater than the Extreme breadth of splicing ear.Satisfy installation requirement, when the encapsulating plastic packaging, can increase the plumpness that gets into the sealing compound in the clamping cover simultaneously.

Further, the wall body away from valve body one side on the said controller housing is provided with opening slot, and being provided with in the said opening slot can be along the baffle plate of opening slot slippage.Be convenient to the installation of the inner components and parts of controller housing.

Further, said valve body is provided with controller and electromagnetic coil plastic packaging parcel all-in-one-piece plastic packaging housing, and the core body of said electromagnetic coil is provided with contact pin, and the controller line plate in the said controller directly welds with contact pin and realizes being electrically connected.Though the plastic packaging housing has some difficulty on processing technology, such configuration saves splicing ear be connected lead, at the cost of counting yield certain advantage is arranged also.

After adopting technique scheme, the utlity model has following advantage: valve body, electromagnetic coil, controller are integrated in one, and the algorithm of having optimized self makes control performance more accurately with superior; Electric control valve has dwindled the space of originally being made up of electric expansion valve, coil of electronic expansion valve, electronic expansion valve controls device greatly, has also reduced manufacture cost, Installation Flexibility and convenience; Also solved simultaneously the phenomenon that interface in the assembling process of electric control valve connects difficulty and encapsulating leakage glue.
