Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to a connector with a built-in spring. Background Technology
[0002] Connectors, also known as plugs or sockets, are generally electrical connectors. They are devices that connect two active devices to transmit current or signals. The male and female terminals, upon contact, can transmit information or current, hence the name connector. RJ45 connectors are a type of connector, primarily used for mating with external crystal heads. They are used for terminating data cables, enabling connections and modifications between equipment and patch panel modules.
[0003] To ensure stable mating with external crystal heads, existing RJ45 connectors use a spring-loaded spring formed by integrally bending the outer shield into the insertion cavity. The spring's elasticity clamps the crystal head. However, this method requires the shield to pass through the front end of the insulating body, resulting in poor overall integrity and aesthetics. Furthermore, it complicates the shield's forming process. Therefore, further improvements to the existing connector structure are necessary. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a connector with a built-in spring, which can effectively solve the problems of poor external integration, poor aesthetics, and complicated shielding shell molding process of existing connectors.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A connector with a built-in spring contact includes an insulating body, a terminal group, a shielding shell, and a spring contact. The front end face of the insulating body is integrally recessed inward to form an insertion cavity that mates with the outside. The terminal group is embedded in the insulating body, with its front end extending inward into the insertion cavity and forming a contact portion, and its rear end extending outward from the insulating body and forming a solder portion. The shielding shell is fitted around the outer periphery of the insulating body. The side wall of the insulating body has a mounting groove communicating with the insertion cavity. The spring contact is disposed in the mounting groove, with one end of the spring contact extending inward into the insertion cavity through the mounting groove, and the other end of the spring contact making contact with the shielding shell.
[0007] As a preferred embodiment, the mounting groove and the insertion cavity are connected by a circular through groove, and one end of the spring piece is provided with a semi-circular protrusion that mates with the through groove, and the protrusion extends inward into the insertion cavity through the through groove.
[0008] As a preferred option, the mounting slots are arranged symmetrically on the left and right, and correspondingly, there are also two spring clips, each of which is set in the corresponding mounting slot.
[0009] As a preferred embodiment, the mounting groove extends forward and backward, and the inner wall of the rear end of the mounting groove is integrally recessed with positioning grooves arranged vertically at intervals; the spring sheet extends forward and backward, and the rear end of the spring sheet is integrally bent inward to form a positioning part that cooperates with the positioning groove.
[0010] As a preferred option, the spring and the shielding shell are formed together by laser welding.
[0011] As a preferred embodiment, the lower end of the insulating body integrally extends downward with positioning posts that cooperate with an external circuit board, and the positioning posts are two horizontally spaced posts.
[0012] As a preferred embodiment, the lower end face of the insulating body is integrally recessed on both the left and right sides to form a buckle groove, and the lower end of the shielding shell is integrally bent inward to form a buckle part that cooperates with the buckle groove.
[0013] As a preferred option, the lower end of the shielding shell extends downwards integrally with a connecting pin that communicates with an external circuit board.
[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
[0015] A mounting groove communicating with the insertion cavity is formed on the side wall of the insulating body; a spring is placed in the mounting groove, with one end of the spring extending inward into the insertion cavity through the mounting groove, and the other end of the spring making contact with the shielding shell. This allows the built-in spring to replace the existing spring formed by bending the shielding shell during manufacturing, eliminating the need for bending the shielding shell during manufacturing. This not only simplifies the manufacturing process of the shielding shell but also eliminates the need for the shielding shell to pass through the front end face of the insulating body, resulting in better external integration and a more aesthetically pleasing overall appearance of the connector.

[0030] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which includes an insulating body 10, a terminal group 20, a shielding shell 30, and a spring piece 40.
[0031] The front end face of the insulating body 10 is integrally recessed to form an insertion cavity 101 for external engagement; the side wall of the insulating body 10 is provided with a mounting groove 102 communicating with the insertion cavity 101. In this embodiment, the mounting groove 102 and the insertion cavity 101 are connected by a circular through groove 103. There are two mounting grooves 102 arranged symmetrically from left to right. The mounting grooves 102 extend from front to back, and the inner side wall of the rear end of the mounting groove 102 is integrally recessed to form positioning grooves 104 arranged vertically at intervals. The lower end of the insulating body 10 integrally extends downward to form positioning posts 11 for engaging with an external circuit board. There are two positioning posts 11 arranged laterally at intervals, which are used to position the insulating body 10 when the connector is installed with the external circuit board. The lower end face of the insulating body 10 is integrally recessed to form retaining grooves 105 on both the left and right sides.
[0032] The terminal group 20 is embedded in the insulating body 10. The front end of the terminal group 20 extends inward into the insertion cavity 101 and forms a contact portion 21. The rear end of the terminal group 20 extends outward from the insulating body 10 and forms a welding portion 22.
[0033] The shielding shell 30 is fitted onto the outer periphery of the insulating body 10. In this embodiment, the lower end of the shielding shell 30 is integrally bent inward to form a fastening part 31 that mates with the fastening groove 105. The fastening part 31 and the fastening groove 105 fix the position of the shielding shell 30, preventing the shielding shell 30 from falling off the insulating body 10. The lower end of the shielding shell 30 integrally extends downward to form a connecting pin 32 that communicates with an external circuit board. The grounding process of the shielding shell 30 is realized through the communication between the connecting pin 32 and the external circuit board.
[0034] The spring piece 40 is disposed in the mounting groove 102, with one end of the spring piece 40 extending inward into the insertion cavity 101 through the mounting groove 402, and the other end of the spring piece 40 making contact with the shielding shell 30. When one end of the spring piece 40 contacts the external crystal head, the grounding process of the external crystal head shell can be achieved through the conduction between the spring piece 40 and the shielding shell 30. In this embodiment, one end of the spring piece 40 has a semi-circular protrusion 41 that cooperates with the through groove 103. The protrusion 41 extends inward into the insertion cavity 101 through the through groove 103. Through the cooperation between the through groove 103 and the protrusion 41, the position of the protrusion 41 can be limited, and the protrusion 41 can also ensure the contact and clamping process with the external crystal head. There are also two spring pieces 40, each of which is disposed in a corresponding mounting groove 102. In other embodiments, there can also be two mounting grooves 102 arranged vertically, and their arrangement is not limited, as long as the clamping contact process with the external crystal head can be achieved. The spring piece 40 extends forward and backward, and its rear end is integrally bent inward to form a positioning part 42 that mates with the positioning groove 104. The positioning part 42 and the positioning groove 104 work together to position the spring piece 40, preventing it from sliding and ensuring the stability of the overall structure. The spring piece 40 and the shielding shell 30 are formed together by laser welding.
[0035] The key design feature of this invention is that a mounting groove communicating with the insertion cavity is formed on the side wall of the insulating body; a spring is placed in the mounting groove, with one end of the spring extending inward into the insertion cavity through the mounting groove, and the other end of the spring making contact with the shielding shell. This allows the built-in spring to replace the existing spring formed by bending the shielding shell during processing, eliminating the need for bending the shielding shell during manufacturing. This not only simplifies the manufacturing process of the shielding shell but also eliminates the need for the shielding shell to pass through the front end face of the insulating body, resulting in better external integration and a more aesthetically pleasing overall appearance of the connector.
[0036] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
