Abstract
Description
Technical Field
[0001] This utility model relates to the field of TYPE-C connector technology, and in particular to a waterproof TYPE-C female connector. Background Technology
[0002] Type-C interfaces are widely used in electronic devices due to their advantages such as reversible insertion and high-speed transmission. The Type-C connector female is a key component for data and power transmission. In the prior art, a common female connector structure includes a housing, a socket tongue, and an injection-molded body. The socket tongue has upper and lower rows of terminals for electrical connection. These terminals are injection molded together with the injection-molded body, which improves structural strength and provides a certain degree of dust and water resistance, as illustrated by a Type-C female connector disclosed in Chinese Patent Publication No. CN218182526U.
[0003] The primary function of the housing is to provide electromagnetic shielding, protect internal components, and prevent physical damage. However, most existing housings are directly fitted onto the outside of the injection-molded body. This method is complex, potentially increasing production costs and reducing efficiency. Furthermore, the housing's positioning relies solely on the fitted structure, which can lead to inaccurate welding during subsequent processes, thus affecting welding quality and reducing connector reliability and yield.
[0004] Based on this, in order to optimize the connection reliability between the existing housing and the injection molded body, we propose a waterproof TYPE-C female connector. Utility Model Content
[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the inability to accurately weld the shell and the injection molded body by simply using a sleeve as a positioning structure. Therefore, a waterproof TYPE-C female connector is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a waterproof TYPE-C female connector, including an injection-molded body with embedded terminal blocks and a housing sleeved on the outside of the injection-molded body, the housing including an upper positioning surface and side positioning surfaces bent into shape on both sides of the upper positioning surface; The upper positioning surface has a positioning bending surface in the middle, and the injection molded body has a positioning step in the middle. The positioning bending surface and the positioning step are used for positioning and stopping. A positioning structure is also provided between the side positioning surface and the injection molded body.
[0007] Furthermore, both sides of the upper positioning surface are formed with first folded surfaces, which are attached to and fixed to the outer side of the side positioning surface.
[0008] Furthermore, a rear stop surface is formed at the tail end of the upper positioning surface, and second folded surfaces are formed on both sides of the rear stop surface. The second folded surfaces are attached to and fixed to the outer side of the side positioning surface.
[0009] Furthermore, the positioning structure includes an opening formed on the end face of the side positioning surface, a positioning flap formed in the opening, and positioning openings provided on both sides of the injection molded body, wherein the positioning flaps and the positioning openings are engaged.
[0010] Furthermore, the tail end of the injection molded body is provided with heat dissipation grooves at each terminal of the terminal block, and a notch is formed at the tail end of the injection molded body. A heat dissipation window is provided above the notch on the upper positioning surface.
[0011] Furthermore, at least one positioning wing is formed at the bottom of the side positioning surface.
[0012] The waterproof TYPE-C female connector proposed in this utility model has the following advantages: By adopting a design of an upper positioning surface, a side positioning surface, and a positioning bending surface for the outer shell, the accuracy of the connection and positioning with the injection molded body is improved. At the same time, the design of the contact positioning structure allows for accurate positioning of the welding position before the shell and the injection molded body are welded and fixed, thus optimizing the connection and protection effect of the shell to the injection molded body. In addition, the shell adopts a whole plate bending and welding forming process, which can greatly improve the convenience of forming and optimize production efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figure 1-4 As one embodiment of this utility model, a waterproof TYPE-C female connector is disclosed. Specifically, the connector includes an injection-molded body 1 with a terminal block 10 embedded in it and a housing 2 sleeved on the outside of the injection-molded body 1. The terminal block 10 includes an upper terminal block and a lower terminal block, which are embedded in the tongue plate of the injection-molded body 1 and extend through to the lower end of the injection-molded body 1. In this solution, the connection and sealing structure of the injection-molded body 1 and the terminal block 10 are not improved, so they will not be described in detail here. Specifically, in this embodiment, the outer shell 2 includes an upper positioning surface 21 and side positioning surfaces 22 bent and formed on both sides of the upper positioning surface 21; The upper positioning surface 21 has a positioning bending surface 23 in the middle, and the injection molded body 1 has a positioning step 11 in the middle. The positioning bending surface 23 and the positioning step 11 are used for positioning and stopping. A positioning structure 3 is also provided between the side positioning surface 22 and the injection molded body 1.
[0017] In other words, by adopting the design of the outer shell 2 consisting of an upper positioning surface 21, a side positioning surface 22, and a positioning bending surface 23, the accuracy of the connection and positioning with the injection molded body 1 is improved. At the same time, the design of contact with the positioning structure 3 allows for accurate positioning of the welding position before the outer shell 2 and the injection molded body 1 are welded and fixed, thereby optimizing the connection and protection effect of the outer shell 2 to the injection molded body 1.
[0018] In some embodiments, the upper positioning surface 21 of the present invention has a first folded surface 211 formed on both sides. The first folded surface 211 is attached to and fixed to the outside of the side positioning surface 22. Specifically, in this embodiment, the first folded surface 211 and the side positioning surface 22 are laser welded together, and a weld point 4 is formed on the first folded surface 211, so as to improve the connection stability between the first folded surface 211 and the side positioning surface 22.
[0019] Furthermore, in this embodiment, the tail end of the upper positioning surface 21 is also formed with a rear stop surface 24. The rear stop surface 24 is used to protect the rear side of the injection molded body 1. In this embodiment, the two sides of the rear stop surface 24 are formed with second folded surfaces 241. The second folded surfaces 241 are attached to and fixed to the outside of the side positioning surface 22. Similarly, in this embodiment, the second folded surfaces 241 are also fixed to the side positioning surface 22 by laser welding. Corresponding weld points 4 are also formed on the second folded surfaces 241.
[0020] It should be noted that after the entire outer shell 2 is stamped, bent and welded, the outer shell 2 can be fitted onto the outside of the injection molded body 2. At this time, the initial positioning between the outer shell 2 and the injection molded body 1 can be achieved through the cooperation of the positioning bending surface 23 and the positioning step 11. Then, the secondary positioning between the outer shell 2 and the injection molded body 1 can be achieved with the help of the design of the positioning structure 3. After the positioning is completed, the outer shell 2 and the injection molded body 1 can be connected and fixed by laser welding. Therefore, corresponding welding points 4 are also formed on the upper positioning surface 21.
[0021] Furthermore, in this embodiment, the upper positioning surface 21 and the two side positioning surfaces 22 together form a U-shaped structural component. A cut is formed between the upper positioning surface 21 and the side positioning surfaces 22 to facilitate bending of the side positioning surfaces 22. Of course, the length of the side positioning surfaces 22 and the length of the upper positioning surface 21 can be the same.
[0022] Based on the above embodiments, the positioning structure 3 in this embodiment includes an opening formed on the end face of the side positioning surface 22, a positioning flap 31 formed in the opening, and positioning openings 32 are provided on both sides of the injection molded body 1, and the positioning flap 31 and the positioning openings 32 are engaged with each other.
[0023] That is, after the outer shell 2 is attached to the outside of the injection molded body 1, the positioning flap 31 can be bent to bend into the positioning opening 32 to position it. At this time, the upper, lower and front and back positioning between the outer shell 2 and the injection molded body 1 can be achieved. After the positioning is completed, the welding and fixing operation can be performed.
[0024] In some embodiments, the tail end of the injection molded body 1 in this invention is provided with heat dissipation grooves 12 at each terminal of the terminal block 10, and a notch 13 is formed at the tail end of the injection molded body 1. The upper positioning surface 21 is provided with heat dissipation windows 25 above the notch 13. Of course, through the design of the heat dissipation grooves 12, the heat of the terminals can be discharged outward along the notch 13 and the heat dissipation windows 25 to optimize the heat dissipation capacity of the entire connector. In addition, in this embodiment, the terminals of the upper terminal block and the lower terminal block of the terminal block 10 are staggered, that is, the heat dissipation grooves 12 are also staggered, so as to ensure that the heat of each terminal is stably dissipated.
[0025] It should be noted that, in this embodiment, at least one positioning wing 26 is also formed at the bottom of the side positioning surface 22. The positioning wing 26 is used to be inserted into the circuit board to achieve soldering positioning. In this embodiment, two positioning wings 26 are formed at the bottom of each side positioning surface 22.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
