Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an integral connector. Background Art

[0002] Existing connector metal parts are as shown in Figure 1 For example, they are of a split structure. After the stamping parts Product A and Product B are welded, they are assembled with Product C. Then, the assembled products are placed into an injection mold for injection molding. The formed product is as shown in Figure 2 For example, to meet the product design requirements. This production process has multiple procedures, a long cycle, and high costs. There is a risk of poor welding quality. Among them, a screenshot of Product A is as shown in Figure 3 For example. The inner hole space of Product A is the same up and down. To prevent glue from running to the inner wall of the inner hole of Product A during the injection molding process, if glue runs to the inner wall of Product A during the injection molding process, it will affect subsequent contact conduction. Assembling Product C at the bottom of Product A will undoubtedly increase the product cost.

[0003] Based on the above defects and deficiencies, it is necessary to improve the existing technology and design an integral connector. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide an integral connector. The metal part is integrally formed, the root of the product is made smaller, ensuring that glue does not run during injection molding, and the subsequent inserted product will not slip, and it has a wider application range than the old product.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide an integral connector, which includes a metal part and an injection molded part. The metal part includes a rolled-round part, a stretching part, and a connecting part that are integrally formed. The rolled-round part is horizontally arranged and formed by a round-packing process. The stretching part is arranged vertically and formed by a stretching process. The rolled-round part and the stretching part are connected together by the connecting part. The metal part is injection molded in an injection mold to form an injection molded part, and the injection molded part wraps the metal part. The stretching part is provided with an insertion hole, and the aperture of the root of the insertion hole is designed to be reduced. A glue-sealing part inserted into the insertion hole is arranged in the injection mold, and the glue-sealing part moves downwards to closely adhere to the inner wall of the insertion hole.

[0006] Preferably, the aperture of the root of the insertion hole decreases from top to bottom, presenting a tapered hole shape.

[0007] Preferably, the glue-sealing part is column-shaped.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The metal part is integrally formed, reducing the original welding process of Product A and Product B;

[0010] The encapsulation part replaces the original product C, reducing the production and assembly processes of product C, saving costs. The encapsulation part belongs to a part of the injection mold and can be reused. It can block the injection plastic and ensure that the injection does not leak.

[0011] The design of reducing the aperture at the root of the stretching part of the metal part can cooperate with the encapsulation part to ensure that it closely adheres to the inner hole and prevent glue leakage. In addition, the conical hole design with a decreasing aperture from top to bottom can facilitate the insertion and subsequent installation of the product, and the product will not slip off. It has a wider application range than the old product. Brief Description of the Drawings

[0020] The following combines the drawings to elaborate on the preferred embodiments of the present invention in detail, so that the advantages and features of the invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] Please refer to Figures 4 to 7 , the embodiments of the present invention include:

[0022] An integral connector, comprising a metal part 1 and an injection molded part 2, wherein the metal part 1 comprises an integrally formed rolled portion 11, a stretching portion 12 and a connecting portion 13, wherein the rolled portion 11 is arranged horizontally and formed by a rounding process, and the stretching portion 12 is arranged in a vertical direction and formed by a stretching process, wherein the rolled portion 11 and the stretching portion 12 are connected together by a connecting portion 13, wherein the metal part 1 is injection molded in an injection mold to form an injection molded part 2, and the injection molded part 2 is wrapped around the metal part 1, wherein the stretching portion 12 is provided with a plug hole 120, wherein the root of the plug hole 120 is designed with a reduced aperture, and wherein a sealing part 3 inserted into the plug hole 120 is provided in the injection mold, wherein the sealing part 3 moves downward to be close to the inner wall of the plug hole 120, and can clamp the subsequent product inserted therein to prevent it from slipping due to loose insertion.

[0023] The diameter of the plug hole 120 decreases from the top to the bottom, forming a tapered hole.

[0024] The sealing part 3 is in a column shape. As the diameter of the root of the plug hole 120 gradually decreases, the sealing part 3 can be inserted into the plug hole 120 to resist the inner wall. During the injection molding process, the sealing part 3 can block the glue and prevent the glue from spreading to the inner wall of the plug hole 120.

[0025] The utility model is an integrated connector, the metal parts are integrated, the root of the product is small, to ensure that the injection molding does not leak glue, and the subsequent loaded products will not slip, and the application range is wider than the old products.
