Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a USB Type-C female connector. Background Technology

[0002] USB is a widely used data transfer interface in user terminals. With the development of USB technology, its transfer speed has become increasingly faster, bringing more and more convenience to users. The USB Type-C interface not only boasts a high data transfer rate but also allows for flexible plugging, making it even more convenient to use.

[0003] In the prior art, more attention is paid to the stability of the overall structure of the female connector or the stability of the overall structure after the USB male connector is inserted. For example, a high-stability USB female connector with application number 202320178770.X discloses a shell and an inner shell that are interlocked and fixed, and at least one of the inner shell and the outer shell is made of plastic material, providing a double-layer reinforcement structure to provide effective protection and reinforcement for the tongue core and the male connector inserted into the female connector. However, the positional accuracy and stability of each component during the core molding process determine the stability and accuracy of the overall structure. Utility Model Content

[0004] The purpose of this utility model is to provide a USB Type-C female connector in which the free end of the first terminal in the upper terminal module is bent and engaged with the gap on the side wall of the lower seat in the lower terminal module. This can achieve a certain degree of stable connection between the upper and lower terminal modules, ensure the accurate positioning of each component of the core after injection molding, and achieve the structural accuracy and stability of the female connector.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a USB Type-C female connector, comprising:

[0006] The core includes an upper terminal module, a lower terminal module, a partition, and an injection-molded shell. The upper terminal module includes an upper base and a first terminal disposed on the upper base. The lower terminal module includes a lower base and a second terminal disposed on the lower base. The upper and lower bases abut against the upper and lower ends of the partition, respectively. Multiple positioning blocks are provided on the side wall of the lower base, with gaps between adjacent positioning blocks. The first terminal is at least partially engaged within these gaps. The injection-molded shell encloses the upper and lower terminal modules, with at least a portion of both ends of the first and second terminals protruding from the injection-molded shell.

[0007] A metal outer shell having an inner cavity, into which the core is embedded.

[0008] As a further optimization, the lower seat is provided with a positioning post, and the partition and the upper seat are respectively provided with positioning holes. The positioning post extends upward into the positioning hole, which can realize the positioning of the upper row of terminal modules, the partition and the lower row of terminal modules, so that the free end of the first terminal can be bent and snapped into the gap on the lower seat.

[0009] As a further optimization, the metal outer shell includes a main shell, one side of which is connected to a vertical plate for closing one end of the inner cavity and abutting against the core. On opposite sides of the vertical plate are cover plates that bend toward one side of the main shell. The cover plates are provided with positioning grooves. The main shell is provided with a positioning plate, which is embedded in the positioning groove to position the cover plates and the vertical plate.

[0010] As a further optimization, the side of the positioning plate away from the vertical plate abuts against the side wall of the positioning groove, which can ensure the stability of the connection.

[0011] As a further optimization, a recess is provided on the side of the positioning plate near the inner cavity, and an extension is provided on the core. The extension is embedded in the recess and can provide certain support for the positioning plate, ensuring the structure and shape of the positioning plate, thereby ensuring the nesting stability with the positioning groove.

[0012] As a further optimization, the connection between the vertical plate and the main shell is provided with multiple clearance grooves. The presence of the clearance grooves allows the vertical plate and the main shell to be connected in the form of connecting ribs, which facilitates the bending and shaping of the vertical plate.

[0013] As a further optimization, the injection-molded shell is provided with a positioning step, which abuts against the main shell.

[0014] As a further optimization, a first support block is provided on each side of the injection-molded shell. The first support block abuts against the vertical plate and works with the positioning step to prevent the core from moving longitudinally.

[0015] As a further optimization, a second support block is provided on each of the opposite sides of the injection-molded shell. The second support block abuts against the two sides of the main shell to prevent the core from moving laterally.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By bending the free end of the first terminal in the upper terminal module and engaging it with the gap on the side wall of the lower seat in the lower terminal module, a certain degree of stable connection between the upper and lower terminal modules can be achieved, which can ensure the accurate positioning of each component of the core after injection molding.

[0018] 2. The stability of the metal shell structure itself, as well as the limiting and positioning of the core, are ensured by the positioning structure of the metal shell itself (such as the nesting and cooperation of the positioning plate and the positioning groove), thereby achieving the stability of the entire female connector structure.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 6 As shown, a USB Type-C female connector includes a metal housing 10 and a core 20 disposed within the metal housing 10. The core 20 includes an upper terminal module 21, a lower terminal module 22, a partition 23, and an injection-molded shell 24. The upper terminal module 21 includes an upper base 211 and a plurality of first terminals 212 disposed on the upper base 211. The lower terminal module 22 includes a lower base 221 and a plurality of second terminals 222 disposed on the lower base 221. The upper base 211 and the lower base 221 respectively abut against... The upper and lower ends of the partition 23 and the side wall of the lower seat 221 are provided with multiple positioning blocks 223. A gap 2230 is provided between adjacent positioning blocks 223. The first terminal 212 is at least partially engaged in the gap 2230. After injection molding, the injection molded shell 24 is wrapped around the upper row terminal module 21 and the lower row terminal module 22. At least part of the ends of the first terminal 212 and the second terminal 222 are exposed outside the injection molded shell 24. The metal shell 10 has an inner cavity 100, and the core 20 is fixed in the inner cavity 100.

[0027] In this invention, to ensure the relative position of each component of the multi-layer structure consisting of the upper terminal module 21, the partition 23, and the lower terminal module 22 is stable during injection molding (wrapping the injection molded shell 24 on the outside of the three components), based on conventional stacking and abutment positioning, the free ends of one side of multiple first terminals 212 are snapped into the gap 2230. On the one hand, this ensures the accurate positioning of the upper terminal module 21 and the lower terminal module 22. On the other hand, by realizing the snap-fit ​​connection between the first terminal 212 and the lower seat 221, the connection stability of the upper terminal module 21 and the lower terminal module 22 can be achieved to a certain extent, which can ensure the stability during injection molding (wrapping the injection molded part 24), thereby ensuring the accurate and stable position of each component of the core 20.

[0028] Preferably, a guide slope is provided on the adjacent side wall of a pair of adjacent positioning blocks 223 on the side away from the lower seat 221, so that the first terminal 212 can be guided into the gap 2230 during the process of bending the free end of the first terminal 212 and snapping it into the gap 2230.

[0029] Furthermore, positioning posts 224 are respectively provided on opposite sides of the upper end of the lower base 221, and a pair of first positioning holes (not shown) are provided on the partition 23 through its body. A pair of second positioning holes 210 are provided on the upper base 211 through its body. The positioning posts 224 pass upward through the first positioning holes and extend into the second positioning holes 224. Through the cooperation of the positioning posts 224 and the pair of positioning holes, the upper row terminal module 21, the partition 23 and the lower row terminal module 22 can be initially positioned. The relative position translational misalignment can be avoided during the process of bending and snapping the free end on one side of the first terminal 212 into the gap 2230.

[0030] The metal outer shell 10 includes a main shell 11. A vertical plate 12 is connected to one side of the main shell 11 to close one end of the inner cavity 100 and abut against the core 20. Cover plates 13 are respectively provided on opposite sides of the vertical plate 12, which are bent toward one side of the main shell 11. The cover plate 13 is provided with a positioning groove 130. The main shell 11 is provided with a positioning plate 111. The positioning plate 111 is embedded in the positioning groove 130 to position the cover plate 13 and the vertical plate 12. The structure on the metal outer shell 10 located outside the inner cavity 100 is initially in a flat state. That is, before the metal outer shell 10 completes the wrapping and positioning of the core 20, the side of the main shell 11 away from the inner cavity 100, as well as the vertical plate 12 and the cover plate 13, are in the same plane. After the core 20 is placed in the inner cavity 100, the vertical plate 12 is formed to block the core 20 by bending. Then, the cover plate 13 is formed to be adjacent to the main shell 11 by bending. The positioning groove 130 on the cover plate 13 is fitted onto the positioning plate 111 on the main shell 11 to ensure the positional stability of the vertical plate 12, thereby ensuring the stability of the core 20 within the metal outer shell 10.

[0031] Preferably, the side of the positioning plate 111 away from the vertical plate 12 forms a surface abutment with the side wall of the positioning groove 130. The surface abutment can effectively prevent the positioning groove 130 from going beyond the end of the positioning plate 111, so as to ensure the stability of the cover plate 13 and the vertical plate 12.

[0032] Furthermore, the positioning plate 111 can be formed by cutting three sides and bending at the corresponding position on the main shell 11. That is, the side of the positioning plate 111 away from its connection with the main shell 11 protrudes from the main shell 11, and a recess 110 is formed on the side of the positioning plate 111 near the inner cavity 100. The core 20 is provided with an extension 231. For example, the extension 231 can be provided on the partition 23 or the injection molded shell 24. The extension 231 is embedded in the recess 110, which can ensure the stability of the structure and shape of the positioning plate 111, thereby ensuring the mutual nesting and mutual constraint of the positioning plate 111 and the positioning groove 130.

[0033] In addition, multiple clearance grooves 1a are provided at the connection between the vertical plate 12 and the main shell 11. The presence of clearance grooves 1a facilitates the bending and forming of the vertical plate 12 relative to the main shell 11.

[0034] Preferably, the injection-molded shell 24 is provided with a positioning step 200, which abuts against the main shell 11 to prevent the core 20 from moving into the inner cavity 100 away from the vertical plate 12; moreover, the injection-molded shell 24 is provided with a first support block 241, which abuts against the vertical plate 12, and together with the positioning step 200, prevents the core 20 from moving longitudinally.

[0035] The injection-molded shell 24 is provided with second support blocks 242 on opposite sides. The second support blocks 242 abut against the sides of the main shell 11 to prevent the core 20 from moving laterally. By preventing longitudinal and lateral movement, the stability of the core 20 within the metal shell 10 can be guaranteed.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
