[0043] Working principle: This product can be composed of a female connector 1, a male connector 2, and a fastening nut 3. The fastening nut 3 is put on one side of the male connector 2, and then the male connector 2 is spliced ​​and fastened with the connecting end of the female connector 1. The female connector 1 is composed of a female connector wire 105, a female connector outer membrane 104, a female connector inner membrane 103, a USB female connector 102, and a female rubber core 101. First, the copper wire 1051 of the female connector wire 105 is welded to the USB female connector welding area 1021, so that the copper wire 1051 is connected to the USB female connector 102. After all the welding is completed, the welded semi-finished product is inserted into the female rubber core jack 1012, and then placed in the injection mold for injection molding to form the female connector inner membrane 103. The female connector inner membrane 103 will completely wrap the welded copper wire 1051, and after wrapping, it has a good protective ability. At the same time, during the molding process, the plastic material of the female inner film 103 will be filled into the female rubber core anti-slip groove 1011. When the female rubber core anti-slip groove 1011 is fully filled with the inner film plastic material, a good connection force will be formed between the female inner film 103 and the female rubber core 101, thereby ensuring that the female inner film 103 will not fall off easily. After the female inner film 103 is formed, it is placed in the injection mold to mold the female outer film 104. In order to ensure that the female outer film 104 and the female inner film 103 have good wrapping force, a number of female inner film grooves 1031 are designed on the female inner film 103. The plastic material of the female outer film 104 will enter the female inner film grooves 1031. When the female inner film grooves 1031 are fully filled with the outer film plastic material, the female outer film 104 and the female inner film A good wrapping force will be formed between the films 103, making it difficult for the female outer film 104 to fall off. In order to facilitate bare-hand plugging and unplugging, the female outer film 104 is also designed with a plurality of female outer film anti-slip portions 1041. The female outer film anti-slip portions 1041 will generate greater friction with bare hands, thereby ensuring that bare hands can easily plug and unplug operations. After the female outer film 104 is formed, it has a second line of protection, which further enhances the dustproof, waterproof and airproof capabilities of the entire product.

[0044] The male connector 2 is composed of a male sealing ring 206, a male connector wire 205, a male connector outer membrane 204, a male connector inner membrane 203, a USB male connector 202, and a male rubber core 201. The male connector wire 205 is welded to the USB male connector welding area 2022 in the same way, and then the welded semi-finished product is inserted into the USB male connector rubber core jack 2011, and then placed in an injection mold for injection molding to form a male connector inner membrane 203. The male connector inner membrane 203 will completely wrap the copper wires of the welded male connector wire 205. After wrapping, it has a good protective ability. At the same time, the plastic material of the male connector inner membrane 203 will be filled into the male connector rubber core groove 2012 during the molding process. When the male connector rubber core groove 2012 is completely filled with the inner membrane plastic material, a good connection force will be formed between the male connector inner membrane 203 and the male rubber core 201, thereby ensuring that the male connector inner membrane 203 will not fall off easily. After the male inner membrane 203 is formed, the male inner membrane 203 is placed in the injection mold to form the male outer membrane 204. In order to ensure that the male outer membrane 204 and the male inner membrane 203 have a good wrapping force, a number of male inner membrane anti-slip ribs 2031 are designed on the male inner membrane 203. After the male outer membrane 204 is formed, the anti-slip ribs 2031 of the male inner membrane 203 will be fully wrapped by the plastic material of the male outer membrane 204. After wrapping, a good wrapping force will be formed between the male outer membrane 204 and the male inner membrane 203, making it difficult for the male outer membrane 204 to fall off. In order to facilitate manual insertion and removal, a number of male outer membrane anti-slip parts 2041 are also designed on the male outer membrane 204. The male outer membrane anti-slip parts 2041 will generate greater friction with the bare hands, thereby ensuring that the bare hands can easily insert and remove the operation. After the male connector outer film 204 is formed, the male sealing ring 206 is put onto the USB male connector outer frame 2021 through the male sealing ring perforation 2061. The male sealing ring 206 and the USB male connector outer frame 2021 are in interference fit. Since the male sealing ring 206 has a certain elasticity, it will not fall off easily under the interference fit and will remain permanently fixed on the USB male connector outer frame 2021.

[0045] After the male head 2 and the female head 1 are assembled, the male head 2 and the female head 1 are plugged together for connection. When the male head 2 is inserted into the female head 1, the fastening nut block 301 will be inserted into the female rubber core 101 along the female rubber core slide groove 1015. After entering, the fastening nut 3 is rotated and continues to slide forward along the female rubber core flange buckle groove 1013. When the fastening nut block 301 slides over the female rubber core flange buckle groove 1013, the male head 2 and the female head 1 are engaged and cannot fall off. Under the action of the male sealing ring 206, the male head 2 can also be waterproof after being fully connected with the female head 1.

[0046] In summary, this product adopts the above unique design. This product has a simple structure and is easy to operate. It is assembled from a detachably connected female head, a male head, and a fastening nut. The female head and the male head are respectively provided with a rubber core, an inner membrane, and an outer membrane, so that they have double-layer protection capabilities, which further enhances the dustproof, waterproof and airproof capabilities of the entire product. The outer membranes of the female head and the male head are respectively provided with anti-slip parts, which are more in line with the principles of human mechanics and are easy to operate. Multiple anti-slip structures are provided between the rubber core, inner and outer membranes, and wires of the female and male heads to ensure the firmness of their respective structures.
