[0002] With the popularization of power intelligent control, the requirement for control reliability is getting higher and higher. With the increase in usage, it is necessary to reduce the overall cost of products. For connector products, by adopting a plastic encapsulation structure to replace part of the metal connection part, the assembly workload can be reduced, the material cost can be lowered, and the plastic encapsulation structure is simple and applicable to most application scenarios.

[0003] The current plastic encapsulation structure uses plastic encapsulation materials to fix and seal wires, connecting pipes, etc. This structure has no problem in indoor applications or short-term outdoor applications. However, if it is used outdoors for a long time, there may be a risk of water leakage between the connecting pipe and the outer plastic encapsulation mold. Especially when the connecting pipe is made of metal material, due to the different expansion coefficients and hardnesses from the plastic encapsulation material, when there are changes in temperature, humidity, etc., gaps will be generated at the joint surface, and water vapor will penetrate into the interior, resulting in a decrease in the insulation resistance of the product, and in severe cases, it may cause a short circuit.

[0004] Therefore, improving the sealing performance between the plastic encapsulation structure and the connecting pipe has become an urgent problem to be solved. Summary of the Utility Model

[0010] Further, the depth of the clamping groove is smaller than the thickness of the sealing ring.

[0011] Further, the material hardness of the sealing ring is smaller than the material hardness of the plastic encapsulation structure and the housing.

[0021] The technical solutions of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0022] Figure 1 and Figure 2 are respectively a partial structural sectional view and a schematic diagram of a plastic encapsulation structure connector provided by an embodiment of the present invention, Figure 3 and Figure 4 are respectively a structural sectional view and a schematic diagram of a plastic encapsulation structure connector provided by an embodiment of the present invention. As shown in combination with Figures 1 to 4 a plastic encapsulation structure connector provided by an embodiment of the present invention includes a connecting pipe 1, a sealing ring 2 and a plastic encapsulation structure, and this connector is used to realize the connection with a cable.

[0023] At least one circle of grooves 11 is provided on the outer wall of the connecting pipe 1, and the sealing ring 2 is clamped in the grooves 11. Optionally, the groove 11 is an annular groove; further optionally, the sealing ring 2 is an annular sealing ring, and the cross-section is circular, rectangular or special-shaped. Among them, except for circular and rectangular, the sealing rings with other cross-sections are all special-shaped, including but not limited to T-shaped, triangular, X-shaped, etc.; optionally, the hardness of the material of the sealing ring 2 is less than the hardness of the materials of the plastic encapsulation structure and the connecting pipe.

[0024] The plastic encapsulation structure includes a plastic encapsulation outer mold 31. One end of the plastic encapsulation outer mold 31 is connected to the outer wall of the connecting pipe 1 and wraps the groove 11. Preferably, one end of the plastic encapsulation outer mold 31 is plastic encapsulated with the outer wall of the connecting pipe 1.

[0025] In an alternative solution, a clamping groove 12 is provided at the bottom of the groove 11. The sealing ring 2 is clamped in the clamping groove 12 provided at the bottom of the groove 11. The width of the clamping groove 12 is smaller than the width of the bottom surface of the groove 11; optionally, the depth of the clamping groove 12 is smaller than the thickness of the sealing ring 2. Optionally, the clamping groove 12 is provided in the middle of the bottom of the groove 11, and the clamping groove 12 is an annular clamping groove. After plastic encapsulation, a thread-like connection structure is formed at the annular groove, strengthening the connection stability between the plastic encapsulation structure and the connecting pipe 1; the material hardness of the sealing ring 2 is less than the material hardness of the plastic encapsulation outer mold 31 and the connecting pipe 1, and it has good compression and rebound performance. After plastic encapsulation, the sealing ring 2 is in a compressed state. When the connecting pipe 1 and the plastic encapsulation structure contract, the sealing ring 2 can continue to contract accordingly. When the connecting pipe 1 and the plastic encapsulation structure expand, the sealing ring 2 can expand accordingly to block the joint surface, avoiding the situation of water ingress due to the generation of gaps at the joint surface between different materials due to different expansion coefficients.

[0026] In an alternative solution, the connector further includes a sleeve 4. The other end of the connecting pipe 1 passes through the sleeve 4, and the sleeve 4 is used to fix the connecting pipe 1. Specifically, a convex limiting structure is provided on the inner wall of one end of the sleeve 4, which is clamped on the outer wall of the connecting pipe 1 to limit the axial and radial movement of the connecting pipe 1.

[0027] A plastic encapsulation structure connector provided by an embodiment of the present invention improves the sealing performance between the connecting pipe and the plastic encapsulation structure by clamping a sealing ring in a groove provided on the outer wall of the connecting pipe.
