Further, described controller and electromagnetic coil are connected by buckle and the encapsulating plastic packaging is integrated.Because the straight forming difficulty is larger, separately after moulding, plastic packaging is integrated, and reduces the difficulty of production technology, is of value to the production in enormous quantities of product.
Further, described controller comprises controller housing and be located at the controller line plate in controller housing, and described electromagnetic coil is provided with the connecting body be connected with the controller housing buckle.Connecting body can be arranged to arbitrary shape and orientation, makes product can adapt to more installation occasion.
Further, on described controller line plate, be electrically connected with splicing ear, be provided with the slot that is connected be electrically connected to electromagnetic coil in described connecting body, described splicing ear with is connected slot cooperation grafting and realizes that the controller line plate is electrically connected to electromagnetic coil.
Further, described connecting body is provided with the clamping cover, and described connection slot is located in the clamping cover, and described controller housing is provided with the buckling groove coordinated with the clamping cover, and sealing compound has all been filled with in controller housing inside and clamping cover inside.Guarantee the reliability and the sealing that connect.
Further, the bottom of described buckling groove is provided with the annular groove coordinated with the end of clamping cover.Further that with controller housing, the two is connected strengthening connection body is reliable and stablize, and while preventing from pouring into sealing compound, leaks simultaneously.
Further, the end face that the inner bottom surface of described connection slot equals to fit with the inner bottom surface that is connected slot on splicing ear to the distance between the end face of clamping cover is to the distance between the inner bottom surface of annular groove.When meeting 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 described controller housing, described 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 described clamping cover.Because splicing ear is to realize being electrically connected to by inserting mode with being connected slot, therefore require both to peg graft rear reliable and stable, so splicing ear is done to further location, contribute to splicing ear and the reliable electrical connection that is connected slot, can also prevent that splicing ear from teetertottering when mounted.
Further, at least have an assemblage gap between the inwall of described position shelf and controller housing, the minimum width of described assemblage gap is greater than the Extreme breadth of splicing ear.Meet installation requirement, can increase the plumpness that enters the sealing compound in the clamping cover simultaneously when the encapsulating plastic packaging.
Further, the wall body away from valve body one side on described controller housing is provided with opening slot, and in described opening slot, being provided with can be along the baffle plate of opening slot slippage.Be convenient to the installation of controller housing internal component.
Further, described valve body is provided with controller and electromagnetic coil plastic packaging parcel all-in-one-piece plastic packaging housing, and the core body of described electromagnetic coil is provided with contact pin, and the controller line plate in described controller directly welds and realizes being electrically connected to contact pin.Although the plastic packaging housing has some difficulty on processing technology, such structure has been saved splicing ear and has been connected wire, at the cost of counting yield, some superiority is also arranged.
After adopting technique scheme, the present invention 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 originally be comprised of electric expansion valve, coil of electronic expansion valve, electronic expansion valve controller greatly, has also reduced manufacture cost, Installation Flexibility and convenience; Also solved the phenomenon that interface in the assembling process of electric control valve connects difficulty and encapsulating leakage glue simultaneously.
