[0025] For those skilled in the art, the specific meanings of the above terms in the present application can be understood in specific circumstances.

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT

[0027] REFERENCE Figures 1-4As shown, the utility model relates to a connector, including first terminal 2, first terminal 2 is hardware, is formed by stamping die processing, do not repeat here, the first terminal 2 including terminal sheet 21, limiting column 22 and connecting column 23 that are connected in turn, connecting column 23 is equipped with sealing glue groove 231, integral injection molding 1, the integral injection molding 1 including plastic main body 12 that covers first terminal 2, connecting column 23 is equipped with sealing glue groove 231, can make plastic main body 12 be clamped at sealing glue groove 231, compared with traditional sealing ring 4 design, can save sealing ring 4 while improving sealing performance.

[0028] As Figure 2 Shown, the axial direction of connecting column 23 deviates from the length direction of terminal sheet 21, specifically, the axial direction of the two ends of limiting column 22 is deviated from each other, and the two ends of limiting column 22 are connected with terminal sheet 21 and connecting column 23, respectively. This satisfies the requirement of limiting displacement of limiting column 22 in plastic main body 12.

[0029] Further, the terminal sheet 21 is formed by stamping, which is generally obtained by punching processing through a stamping die. The limiting column 22 and the connecting column 23 are both formed by round wrapping. The round wrapping is a cylindrical product obtained by extrusion molding in the upward or lateral direction of the upper die and the lower die of the stamping die. After completing the round wrapping process, the limiting column 22 is bent to form. The middle part of the limiting column 22 is bent to form, which is to limit the movement of the plastic main body 12, so that the first terminal 2 does not separate from the plastic main body 12 after a long time of use.

[0030] As Figure 2 Shown, the sealing glue groove 231 is located at the joint between the connecting column 23 and the limiting column 22. The specific position of the sealing glue groove 231 is selected according to the actual situation. In addition, the plastic main body 12 is formed by one-time injection molding, without the need for multiple processing procedures, with no or few seams, one-time forming, simple process, high processing quality; the raw materials put into the mold can be used for product forming, reducing raw material loss and waste.

[0031] Further, as described above, the plastic main body 12 is arranged in a stepped manner, and the size is selected according to the design requirements. The size of the accommodating hole 11 of the plastic main body 12 matches the first terminal 2, that is, Figure 2 In the explosion diagram, the first terminal 2 is separated from the plastic main body 12, leaving an accommodating hole 11 on the plastic main body 12. In fact, the connector is an integral part, and the plastic main body 12 completely covers the covering part of the first terminal 2, and there is actually no accommodating hole 11. Specifically, Figures 2-4 It can be seen that the first terminal 2 is provided with two, the axial direction of the two connecting columns 23 is parallel, and the two terminal sheets 21 are arranged parallel to each other.

[0032] As Figure 5 shown, the conventional connector product includes a second terminal 3 (design without sealing groove 231), a sealing ring 4, a rubberized positioning column, a rubber plug 6 and an upper cover 7. The second terminal 3 is first rubberized and molded to obtain the rubberized positioning column, then the rubber plug 6 and the upper cover 7 are respectively injection molded, and finally the rubber plug 6, the sealing ring 4 and the upper cover 7 are sequentially sleeved on one end of the second terminal 3 to obtain the assembled connector finished product.

[0033] In view of the deficiencies of the prior art, the technical scheme of the present application makes the following innovations: first, the positioning column, the rubber plug 6 and the upper cover 7 are integrated and injection molded at one time; a sealing groove 231 is added to the first terminal 2 to improve the sealing performance after injection molding; the one-time injection molding and the structural improvement of the first terminal 2 improve the air tightness and cancel the O-shaped sealing ring 4.

[0034] In the utility model, the assembly and cooperation relationship of each component and the material are prior art or material, and the skilled person in the art can directly purchase or order according to the required product model and specification.

[0035] The above is only the preferred specific embodiment of the utility model, and the specific structure and characteristics of the known scheme are not described in detail. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and any skilled person in the art can make equivalent replacement or change according to the technical scheme and utility model concept of the utility model within the technical range disclosed by the utility model. It should be covered within the protection range of the utility model.
