[0002] With the rapid development of technology, intelligent devices are becoming increasingly widespread. In fields such as automobiles, new energy, aviation, and medical care, USB female connectors are used when connecting devices. A USB female connector is a safe, energy-saving, universal socket assembly with a USB interface. It is widely used in various electronic devices and products to facilitate data transmission and power access.

[0003] Most existing USB female connectors are installed and fixed to the PCB board by soldering. However, the existing USB female connector shells have no screw holes and the joint lines of the shells are not laser-welded to improve strength, resulting in poor overall strength of the USB female connectors. Consequently, the mechanical strength of the USB female connectors after being soldered to the PCB board is low, making them unsuitable for some fields that require high strength and high reliability, resulting in poor applicability of USB female connectors.

[0025] Please refer to Figures 1-6This utility model proposes a USB female connector with screw holes, including a metal shell 1, a fixing seat 2 inside the metal shell 1, and a connecting assembly between the metal shell 1 and the fixing seat 2. The connecting assembly can connect and fix the metal shell 1 and the fixing seat 2. The metal shell 1 has a cavity inside, which is correspondingly arranged with the fixing seat 2. The connecting assembly includes multiple sets of limiting ports 3, multiple sets of fasteners 4, screw plates 5, threaded holes 6, two sets of fixing feet 7, multiple sets of solder points 8, multiple sets of limiting protrusions 11, multiple sets of fasteners 12, multiple sets of plug interfaces 13, and two sets of limiting grooves 14. The multiple sets of limiting ports 3 are evenly distributed in the metal shell 1. On the bottom surface, multiple sets of the aforementioned fasteners 4 are symmetrically arranged on the side wall surface of the metal housing 1. The screw plate 5 is integrally set at the end of the metal housing 1, and the threaded hole 6 is opened on the surface of the screw plate 5. Two sets of the aforementioned fixing feet 7 are symmetrically arranged at the bottom of the metal housing 1. Multiple sets of the aforementioned welding points 8 are laser-welded to the joint at the top of the metal housing 1. A through-hole 9 is opened at the end of the inner wall of the metal housing 1. Two sets of elastic clips 10 are symmetrically arranged on the inner wall of the through-hole 9. The ends of the elastic clips 10 are arc-shaped. Multiple sets of the aforementioned limiting protrusions 11 are evenly distributed at the bottom of the fixing seat 2. Multiple sets of the aforementioned fasteners 12 are symmetrically arranged on the side wall of the fixing seat 2. Multiple sets of the aforementioned insertion interfaces 13 are opened on the bottom surface of the metal housing 1. On the side wall surface of the fixing base 2, two sets of limiting grooves 14 are formed on the end surface of the fixing base 2. The limiting protrusions 11 are correspondingly arranged with the limiting openings 3, and the fastening points 12 are correspondingly arranged with the fastening positions 4. The cross-section of the fastening point 12 is wedge-shaped. A first terminal 15 is inserted and installed in the insertion interface 13, and a second terminal 16 is inserted and installed in the insertion interface 13 and located below the first terminal 15. There are two sets of both the first terminal 15 and the second terminal 16. The overall length of the first terminal 15 is greater than the overall length of the second terminal 16. The side walls of both the first terminal 15 and the second terminal 16 are provided with locking protrusions. With the arrangement of two sets of the first terminal 15 and the second terminal 16... This facilitates subsequent soldering and saves PCB wiring space. All terminals 15 and 16 are bent at 90 degrees by an automatic machine. With the setting of limiting protrusions 11, limiting ports 3, latches 4, latch points 12, and elastic clips 10, the metal shell 1 and the fixing base 2 limit each other after assembly, and have a high anti-reverse force. With the setting of screw plate 5, threaded holes 6, and solder points 8, the high-strength screw plate 5 and the client's shell can be connected and fixed together by M3 screws through the threaded holes 6, thereby completing the locking of the metal shell 1 and the client's shell bracket. At the same time, the metal shell 1 is laser-welded with multiple sets of solder points 8, which improves the impact resistance of the metal shell 1.

[0026] In this embodiment

[0027] When using this USB female connector with screw holes, during the manufacturing process, the operator first removes the secondary material from terminals 15 and 16 and bends them 90 degrees. Then, terminals 15 and 16 are riveted into their corresponding connectors 13. Next, the main material from terminals 15 and 16 is removed, and the metal housing 1 is riveted onto the outside of the mounting base 2. This completes the manufacturing of the USB female connector. The double-row arrangement of two sets of terminals 15 and 16 facilitates subsequent soldering and saves PCB wiring space. Furthermore, all terminals 15 and 16 are bent 90 degrees by an automatic machine, which facilitates stamping production and saves electroplating costs. (The last sentence appears to be incomplete and possibly refers to a different process.) With the configuration of port 3, latch 4, latch point 12, and elastic clip 10, the metal shell 1 and the fixed base 2 mutually limit each other after assembly, providing a high anti-reverse force and ensuring the stability of the USB female connector during use. With the configuration of screw plate 5, threaded hole 6, and solder point 8, the high-strength screw plate 5 and the client's shell can be connected and fixed together by M3 screws through threaded hole 6, thereby completing the locking of the metal shell 1 and the client's shell bracket. At the same time, the metal shell 1 is laser-welded with multiple sets of solder points 8, which improves the impact resistance of the metal shell 1 and enhances the overall mechanical strength, ensuring the use of the USB female connector in fields with high product reliability requirements such as automobiles, new energy, and aviation, thereby improving the applicability of the USB female connector.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
