Abstract
The utility model discloses a positioning structure of a stator coil of an electronic expansion valve, which belongs to the field of electronic expansion valves, wherein the side surface of the stator coil is provided with a junction box, the lower end of the stator coil is provided with a first connecting part sleeved on the end part of a valve body and a second connecting part used for fixing a copper connecting pipe, and the stator coil, the junction box, the first connecting part and the second connecting part are integrally formed by injection molding; the utility model discloses a below opening part at the second connecting portion is equipped with the screens groove that is used for holding metal jump ring, and the metal jump ring is including being used for the card to establish at the jump ring body of copper takeover outer lane, by the spacer that this tip of body of jump ring is bent to the screens inslot. When the clamp spring body of the metal clamp spring is expanded and then clamped on the copper connecting pipe, the positioning plate is inserted into the positioning groove, so that the second connecting part and the metal clamp spring form a whole and then are tightly attached to the outer ring of the copper connecting pipe, looseness cannot be generated between the metal clamp spring and the second connecting part, and the operation stability of the electronic expansion valve is improved.
Description
Technical Field
The utility model relates to an electronic expansion valve field, concretely relates to positioning structure of electronic expansion valve stator coil.
Background
The electronic expansion valve is widely applied to an air conditioning system, the automatic adjustment of the flow of a refrigerant is realized, and finally the air conditioning system achieves the effects of accurate temperature control and energy conservation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a strengthen jump ring and stator coil structural stability's stator coil's location structure.
The technical scheme of the utility model is that: a positioning structure of a stator coil of an electronic expansion valve is characterized in that the stator coil is in a cylindrical step shape, a junction box is arranged on the side face of the stator coil, a first connecting part used for being sleeved at the end part of a valve body is arranged at the lower end of the stator coil, a second connecting part used for fixing a copper connecting pipe extends downwards from the lower end face of the first connecting part, a metal clamp spring is arranged in the second connecting part, and the stator coil, the junction box, the first connecting part and the second connecting part are integrally formed through injection molding; the metal snap spring comprises a snap spring body used for being clamped on the outer ring of the copper connecting pipe and a positioning sheet bent from the end part of the snap spring body to the end part of the clamping groove.
In a further technical scheme, an included angle between the two positioning pieces is 90-180 degrees.
In a further technical scheme, an included angle between the two positioning pieces is 120 degrees.
The utility model has the advantages that:
the utility model has simple structure, the metal snap spring is arranged in the second connecting part which is integrated with the stator coil and is fixed in the clamping groove of the second connecting part through the positioning sheet; when the jump ring body of metal jump ring propped open the back card and establish on copper is taken over, the spacer of jump ring body both sides received the extrusion and removed to constant head tank tip direction for the metal jump ring is hugged closely on the second connecting portion, and forms a whole after tightly hoop in the outer lane that copper was taken over with the second connecting portion, to sum up, the utility model discloses a structure can guarantee can not produce between metal jump ring and the second connecting portion and become flexible, thereby improves electronic expansion valve operation's stability.
