Technical Field

[0001] The present invention relates to the field of electromagnetic valves, and more particularly to a electromagnetic valve connector structure. Background Art

[0002] Solenoid valves generally require integrated connectors to achieve power supply and control. Currently, there are two main types of connectors on the market, one is the integral injection molding form, and the other is the split assembly form.

[0003] Most integral injection-molded connectors require complex molds and need to be molded in two injection moldings, which is costly and has complicated processes.

[0004] The existing structure connection reliability of split-type connectors is difficult to guarantee, and they are prone to loosening and structural damage under severe vibration and impact conditions. In addition, the split-type assembled connectors have no effective protection, and the exposed wires are prone to bumps and damage. Summary of the invention

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A solenoid valve connector structure comprises a valve body, a winding frame, a connector shell and a protective cover; the connector shell is detachably connected to the winding frame and is fixedly connected to the valve body; the protective cover is detachably connected to the connector shell.

[0008] Furthermore, the connector housing is snap-connected to the winding frame; the protective cover is snap-connected to the connector housing, and a positioning component is provided between the protective cover and the winding frame.

[0009] Furthermore, the positioning assembly includes a slider disposed on the winding frame, and a slide groove disposed on the inner wall of the protective cover and cooperating with the slider.

[0010] Furthermore, the slide groove is a dovetail groove.

[0011] Furthermore, the connector housing is symmetrically provided with limit blocks, and the protective cover is provided with limit slots that cooperate with the limit blocks.

[0012] Furthermore, a first partition groove is provided on the protection cover at a position close to the limit clamping opening.

[0013] Furthermore, the connector housing is symmetrically provided with L-shaped limiting buckles that cooperate with the winding skeleton.

[0014] Furthermore, positioning plates capable of contacting the side walls of the winding skeleton are symmetrically arranged on the connector housing.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The modular assembly structure is adopted, and the different connector interfaces have good interchangeability, which solves the problem of complex process and high cost of integral injection molding connectors;

[0019] 2. The protective cover can effectively prevent the wires and terminals from being damaged by collision due to exposure;

[0020] 3. Slide blocks and slide grooves are used, and the slide grooves are dovetail grooves, which play a positioning role on the one hand and a bearing role on the other hand, which can improve the reliability of the connection;

[0021] 4. After the connector is assembled, the connector housing is firmly connected to the valve body by hot riveting, which increases the reliability and redundancy of the structural connection and can withstand greater impact and vibration;

[0022] 5. The use of positioning blocks and positioning slots can increase structural rigidity and reliability and evenly distribute structural stress. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 2 Two pins 5 are arranged on the winding skeleton 4, and the pins 5 include a fixed section 51, a connecting section 52 and a wiring section 53; wherein, the fixed section 51 is firmly embedded in the winding skeleton 4 to play a positioning and connecting role, the connecting section 52 is inserted into the connector housing 3 to achieve electrical connection, and the wiring section 53 is used to connect with the coil; a T-shaped partition plate 35 is arranged on the connector housing 3 to separate the two pins 5.

[0034] Reference Figure 2 and Figure 3Two L-shaped limit buckles 32 that cooperate with the winding skeleton 4 are symmetrically arranged on the connector shell 3, and a positioning block 36 is arranged on the connector shell 3. A positioning slot 13 that cooperates with the positioning block 36 is provided on the valve body 1. The limit buckle 32 cooperates with the positioning block 36, so that the displacement of the connector shell 3 along the length direction of the connecting section 52 can be limited; two fixing columns 37 are symmetrically arranged on the connector shell 3, and a fixing slot 11 that cooperates with the fixing column 37 is provided on the valve body 1, and a fixing groove 12 is provided on the inner side wall of the fixing groove 11; in this embodiment, the fixing column 37 and the valve body 1 are hot-riveted to achieve a fixed connection. After hot riveting, part of the fixing column 37 will be filled into the fixing groove 12, so as to limit the displacement of the connector shell 3 along the direction perpendicular to the length direction of the connecting section 52.

[0035] Reference Figure 2 The connector housing 3 is symmetrically provided with positioning plates 34 that can contact the side walls of the winding skeleton 4.
