Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a USB TYPE C female connector. Background Art

[0002] Currently, the common USB TYPE C female connector is usually composed of an insulating body, a plurality of conductive terminals, and a metal shell covering the insulating body. The metal shell is provided with a plug hole, and the insulating body has a tongue extending into the plug hole. A plurality of conductive terminals are arranged on the upper and lower sides of the tongue. However, in actual long-term use, connectors with this structure still have the following problems: 1. The metal shell is usually composed of two upper and lower shells that are simply snapped together, resulting in a low overall firmness of the product and an inability to guarantee the overall service life and quality of the product; 2. The wear resistance of the insulating body inside the plug hole is poor, and it is severely worn under long-term plugging and unplugging, further reducing the overall service life and quality of the product; 3. The tongue is relatively thin and prone to breakage, resulting in problems such as poor contact, which further reduces the overall service life and performance of the product and needs to be improved. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a USB TYPE C female connector that can effectively enhance the overall firmness, wear resistance and strength of the product to solve the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a USB TYPE C female connector, comprising an insulating body and a metal shell covering the insulating body. The metal shell is composed of an upper shell covering the upper surface of the insulating body and a lower shell covering the lower surface of the insulating body, and is provided with an insertion hole. One end of the insulating body extends into the insertion hole and is provided with a tongue extending therefrom. Conductive terminals are arranged on the upper and lower sides of the tongue. The upper and lower shells are connected by laser welding. Wear-resistant metal sheets are fixed to the upper and lower sides of the end of the insulating body extending into the insertion hole, and a reinforcing metal rib is embedded in the middle of the tongue.

[0005] Preferably, the insulating body is made of plastic.

[0006] Preferably, the metal shell is made of 304 stainless steel.

[0007] Preferably, the outer surface of the metal shell is provided with a foam aluminum coating.

[0008] The beneficial effects of the present invention are: 1. The upper shell and the lower shell are connected by laser welding, which can greatly enhance the overall firmness of the product. This structure is welded on the PCB board, which is more stable and reliable, and can more effectively ensure a longer service life and better use quality of the product; 2. The arrangement of wear-resistant metal sheets on the upper and lower sides of one end of the insulating body extending into the plug hole can effectively enhance the wear resistance of the corresponding position, provide good wear-resistant protection for the corresponding position, reduce the wear caused by long-term plugging and unplugging, and thus further improve the use quality and service life of the product; 3. The arrangement of the reinforcing metal ribs embedded in the tongue can effectively improve the strength of the entire tongue, effectively prevent the tongue from breaking during use, more effectively ensure the overall use performance of the product, improve the overall service life of the product, and be more practical.

[0014] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0015] like Figures 1 to 4 The figure shows a USB Type-C female connector, comprising an insulating body 1 and a metal housing 2 covering the insulating body 1. The metal housing 2 comprises an upper housing 3 covering the upper surface of the insulating body 1 and a lower housing 4 covering the lower surface of the insulating body 1. The metal housing 2 defines an insertion hole 5. One end of the insulating body 1 extends into the insertion hole 5 and is provided with a tongue 6 extending therefrom. Conductive terminals 7 are arranged on the upper and lower sides of the tongue 6. The upper and lower housings 3 and 4 are connected by laser welding. Wear-resistant metal plates 8 are fixed to the upper and lower sides of the end of the insulating body 1 extending into the insertion hole 5. A reinforcing metal rib 9 is embedded in the middle of the tongue 6.

[0016] The upper shell 3 and the lower shell 4 are connected by laser welding, which can greatly enhance the overall firmness of the product. This structure is welded on the PCB board, which is more stable and reliable, and can more effectively ensure a longer service life and better quality of use of the product. The setting of the wear-resistant metal sheets 8 on the upper and lower sides of one end of the insulating body 1 extending into the plug hole 5 can effectively enhance the wear resistance of the corresponding position, provide good wear-resistant protection for the corresponding position, reduce the wear caused by long-term plugging and unplugging, and thus further improve the quality of use and service life of the product. 3. The setting of the reinforcing metal ribs 9 embedded in the tongue 6 can effectively improve the strength of the entire tongue 6, effectively prevent the tongue 6 from breaking during use, and more effectively ensure the overall performance of the product, improve the overall service life of the product, and be more practical. The wear-resistant metal sheet 8 and the reinforcing metal ribs 9 can both be made of existing alloy steel materials with alloy elements such as chromium and nickel to ensure the high strength and high wear resistance of the required materials.
