Description

Technical Field

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

[0002] A USB Type-C female connector, in short, is a type of USB interface designed for reversible insertion. This means users can easily plug in USB devices without needing to distinguish between the correct orientation. This design greatly improves ease of use and reduces the inconvenience caused by plugging in the wrong way.

[0003] Current USB Type-C female connectors primarily consist of an insulating body and a shell. The insulating body includes a base and a tongue extending forward from the base, and multiple terminal pins are disposed on the insulating body. The shell covers the insulating body. In existing technology, the number of terminal pins is typically 24 pins or 16 pins. This type of USB Type-C female connector complies with the requirements of the Type-C Association specification, allowing for both charging and data transfer. Meanwhile, 3-pin, 6-pin, and 8-pin connectors have also emerged in the market. The frame size, tongue length, center plate width, and terminal pin position dimensions of these USB Type-C female connectors all conform to the dimensional requirements of the Type-C Association, enabling charging or simple data transfer functions.

[0004] However, compared to simple charging functionality, current USB Type-C female connectors still have redundant terminal pins, resulting in more components, a more complex structure, and higher costs. For certain products (such as power tools, electric toothbrushes, etc.), no data signal pins or PCB interconnection are needed; only power and ground pins are required. However, there are currently no two-pin USB Type-C female connectors available, further increasing the manufacturing cost of these specific products. Therefore, it is necessary to research a solution to these problems. Utility Model Content

[0042] Please refer to Figures 1 to 7 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an insulating body 10 and a housing 20.

[0043] The insulating body 10 includes a base 11 and a tongue plate 12 extending forward from the base 11. The insulating body 10 is made of one-piece plastic material.

[0044] The outer shell 20 covers the insulating body 10. Specifically, the outer shell 20 includes a shielding shell 21 and a plastic shell 22. The shielding shell 21 covers the insulating body 10 and is made of iron, formed by stamping. The plastic shell 22 is injection molded and covers the shielding shell 21 to seal it and achieve waterproofing of the outer periphery of the shielding shell 21. Furthermore, the rear end of the plastic shell 22, the rear of the base 11, and the rear of the shielding shell 21 form a dotted groove 201, which is filled with glue and cured to form a sealing element 31. The front end of the shielding shell 21 is formed with a waterproof ring 32, which is made of silicone or rubber. The waterproof ring 32 is located in front of the plastic shell 22 and is attached and fixed to the front end face of the plastic shell 22 to achieve waterproofing at the insertion connection. Furthermore, the plastic housing 22 has fixing ears 221 extending outward from both sides of its rear end, and each fixing ear 221 has a fixing hole 202 to enable installation, fixing and connection with the outside.

[0045] The insulating body 10 is provided with a power supply PIN 40 and a grounding PIN 50; in this embodiment, the power supply PIN 40 and the grounding PIN 50 are both embedded and fixed together with the insulating body 10 to achieve a waterproof function, specifically:

[0046] The power PIN 40 includes a first body 41, a first solder foot 42, and two first contact portions 43. The first body 41 is located inside the insulating body 10. The first solder foot 42 extends backward integrally from the first body 41 and protrudes outside the base 11. The two first contact portions 43 extend forward integrally from both ends of the first body 41, and the two first contact portions 43 protrude from the upper and lower surfaces of the tongue plate 12. In this embodiment, the power PIN 40 is formed by bending a metal sheet through stamping. The first body 41 has a U-shaped structure. The first solder foot 42 extends horizontally backward outside the base 11, and a first wire hole 401 is provided at the tail end of the first solder foot 42 to facilitate wire bonding. The connection is stable and reliable. Furthermore, the first solder foot 42 protrudes outward through the sealing member 31 to achieve waterproofing.

[0047] The grounding PIN 50 includes a second body 51, a second solder foot 52, a connecting portion 53, and two second contact portions 54. The second body 51 is located inside the insulating body 10. The second solder foot 52 and the second body 51 are located outside the left and right sides of the power PIN 40, respectively, and the second solder foot 52 extends out of the base 11. The connecting portion 53 is integrally formed and connected between the second body 51 and the second solder foot 52. The connecting portion 53 is arranged around the two first contact portions 43 and embedded in the tongue plate 12 to increase the structural strength of the head of the tongue plate 12. The two second contact portions 54 extend forward integrally from the front end of the second body 51 and the front end of the second solder foot 52, respectively. The two second contact portions 54 are exposed on the upper and lower surfaces of the tongue plate 12, and the two second contact portions 54 are located outside the two first contact portions 43. In this embodiment, the grounding PIN 50 is formed by bending a metal sheet by stamping. The second solder foot 52 extends horizontally backward out of the base 11. A second wire-through hole 501 is provided at the tail end of the second solder foot 52 for wire bonding, ensuring a stable and reliable connection. Furthermore, the second solder foot 52 extends outward through the sealing member 31 to achieve waterproofing. The connecting portion 53 includes a first longitudinal section 531, a first transverse section 532, a U-shaped section 533, a second transverse section 534, and a second longitudinal section 535, which are integrally formed and connected in sequence. The first longitudinal section 531 and the second longitudinal section 535 are located inside the two second contact portions 54 and are arranged parallel to each other at intervals. The first transverse section 532, the U-shaped section 533, and the second transverse section 534 are located in front of the power PIN 40.

[0048] Furthermore, a hook 60 is inlaid and fixed on both the left and right sides of the insulating body 10, and the two hooks 60 are symmetrically arranged and protrude from the left and right sides of the tongue plate 12 respectively.

[0049] The assembly process of this embodiment is described in detail below:

[0050] First, the power PIN 40, ground PIN 50, and two hook pieces 60 are stamped and formed. Then, the power PIN 40, ground PIN 50, and two hook pieces 60 are placed into an injection mold and injection molded to form an insulating body 10, so that the power PIN 40, ground PIN 50, and two hook pieces 60 are all embedded and fixed together with the insulating body 10. Then, the stamped shielding shell 21 is wrapped around the insulating body 10. Next, a plastic shell 22 is injection molded on the shielding shell 21. Then, a waterproof ring 32 is formed at the front end of the shielding shell 21. Finally, glue is filled into the glue dispensing groove 201 and cured to form a sealing element 31.
