Abstract
The utility model relates to an electrical expansion valve winding applied to solenoid valves or step motors, which comprises a framework, windings arranged on the framework, and a stator shell sleeved outside of the framework and the windings. The utility model is characterized in that an insulated sleeve is arranged on the elicited parts of the elicited end of the winding on the framework. In the process of injection moulding, pheromones of deflection and break of elicited ends from punching are effectively avoided, after the process of injection, the stator shell is arranged outside of the combined framework and the winding and a low cost electrical expansion valve winding with good capacity is formed.
Description
[technical field]
The utility model relates to the loop construction on the electric expansion valve, and can be used for electromagnetically operated valve and stepping motor.
[background technology]
Loop construction on the existing electric expansion valve comprises the winding 2 on skeleton 6, the skeleton and is enclosed within stator casing 1 outside the two, in the manufacture process of product, winding technique on skeleton, is carried out injection process afterwards to improve the insulation property of product.Yet the coil of this structure, the exit 7 of its winding are directly exposed to outer (seeing Fig. 3, Fig. 4), the influence of the HTHP injection raw material that is flowed in the injection moulding process, the exit of winding can be dashed disorderly, cause the winding energising chaotic, reduce the qualification rate of coil, influence the performance of coil; And some product is after winding technique is finished, and welding lead position on skeleton can reduce the hot strength of lead-in wire like this, and injection moulding process can thrust lead-in wire.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the existing existing deficiency of loop construction, and a kind of simple in structure, well behaved coil of electronic expansion valve is provided, and improves it simultaneously and makes qualification rate.For this reason, the utility model is taked following technical proposals:
Coil of electronic expansion valve comprises the winding on skeleton, the skeleton and is enclosed within stator casing outside the two, it is characterized in that the extraction location of winding exit on the described skeleton is provided with insulating sheath.
Described coil of electronic expansion valve is characterized in that having a protuberance on the described skeleton, on this protuberance contact pin is installed, and the winding exit is connected on the contact pin, and described insulating sheath is installed on this protuberance and is enclosed in outside the contact pin.
Described coil of electronic expansion valve is characterized in that described skeleton is cylindric, the electromagnetism pawl utmost point in its internal fixation, and described stator casing is two, inner circumferential surface has and the extremely corresponding magnetic pole tooth of interior electromagnetism pawl.
Characteristics of the present utility model are that the extraction location of winding exit on skeleton is provided with insulating sheath, in the injection process process, effectively avoid winding exit quilt towards phenomenon askew, that thrust, after treating that injection moulding is finished, outside the skeleton of one and winding, stator casing is installed, thereby is formed well behaved cheap coil of electronic expansion valve.

Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of existing product.
Fig. 4 is the vertical view of Fig. 3.
[embodiment]
As shown in Figure 1, 2, coil of electronic expansion valve of the present utility model, comprise the winding 2 on cylindric skeleton 6, the skeleton and be enclosed within upper and lower stator casing 1 outside the two, has a protuberance 5 on the skeleton 6, contact pin 4 and the insulating sheath 3 that is enclosed in outside the contact pin are installed on this protuberance 5, and winding exit 7 is connected on the contact pin 4.The electromagnetism pawl utmost point in the skeleton internal fixation, two shell inner peripheral surfaces have and the extremely corresponding magnetic pole tooth of interior electromagnetism pawl.
During manufacturing, contact pin is inserted in protuberance, and on skeleton the coiling winding, the winding exit is connected on the contact pin, the interior electromagnetism pawl utmost point is fixed in the skeleton, insulating sheath is installed in protuberance and is enclosed in outside the contact pin, inserts afterwards and carries out injection process in the mould, will place the complete loop product of formation in the stator casing up and down that has magnetic pole tooth at last through the coil windings of injection process.Because the winding exit is insulated protective jacket and surrounds, in the injection moulding process HTHP injection raw material is isolated, so the qualification rate in the injection moulding process can be greatly improved, properties of product are good.
Claims (3)
1, coil of electronic expansion valve comprises the winding (2) on skeleton (6), the skeleton and is enclosed within stator casing (1) outside the two, it is characterized in that described skeleton (6) goes up the extraction location of winding exit (7) and be provided with insulating sheath (3).
2, coil of electronic expansion valve according to claim 1, it is characterized in that having a protuberance (5) on the described skeleton (3), contact pin (4) is installed on this protuberance (5), winding exit (7) is connected on the contact pin (4), and described insulating sheath (3) is installed in this protuberance (5) and goes up and be enclosed in outside the contact pin (4).
3, coil of electronic expansion valve according to claim 1 and 2 is characterized in that described skeleton (6) for cylindric, the electromagnetism pawl utmost point in its internal fixation, and described stator casing is two, inner circumferential surface has and the extremely corresponding magnetic pole tooth of interior electromagnetism pawl.
