[0040] First, weld the wire copper wire 102 to the USB male head welding area 405 of the USB male head 4. After welding, cover the USB male head lid 404 on the USB male head rubber core 403. After covering, the wire copper wires 102 will be separated by the USB male head lid partition 402, so as to avoid short - circuit phenomena between the copper wires.

[0041] After the lid is covered, put the semi - finished product with the welded wire into the USB male head front shell 401, and then cover the USB male head rear shell 407 on the USB male head front shell 401. After covering, use a tooling to tightly rivet the wire outer skin of the wire 1 with the USB male head rear shell riveting wire clip 406 on the USB male head rear shell 407. After riveting, when the wire 1 is subjected to an external impact, the wire outer skin 101 will bear the external force so that the welded copper wire part is not easily detached.

[0042] After the wire outer skin 101 is riveted, put the product with the wire into the jack of the male rubber core 5, and then put it together with the male rubber core 5 into a plastic mold for the formation of the male inner film 3. The main purpose of the formation of the male inner film 3 is to better protect the welding area. To enhance the adhesion between the male inner film 3 and the male rubber core 5, male rubber core slots 501 are designed on the male rubber core 5. When the male inner film 3 is formed, the glue amount of the male inner film 3 will be injected into all empty places such as the male rubber core grooves through the pressure of the injection molding machine for filling. After filling, the formation of the male inner film is completed.

[0043] To further enhance the protection of the product, after the male inner membrane 3 is formed, the formed male inner membrane 3 is placed into the plastic mold of the male outer membrane for further forming. To ensure good adhesion between the male inner membrane 3 and the male outer membrane 2, a number of male inner membrane grooves 301 are also designed on the male inner membrane 3. During the injection molding process of the male outer membrane 2, the glue of the male outer membrane 2 will also be injected under the pressure of the injection molding machine into all the empty places such as the male inner membrane grooves 301 for filling. When the male inner membrane grooves 301 are all filled with glue, it will form good wrapping with the male outer membrane 2.

[0044] To protect the wire from being easily broken, a male outer membrane wire clip 201 is also designed on the male outer membrane 2. When the wire 1 sways due to external force, the male outer membrane wire clip 201 will bear and absorb most of the external force, thus effectively protecting the wire 1 from being easily broken.

[0045] When the product is installed, the male outer membrane 2 will be directly contacted by hand. To improve the hand feeling and friction, a number of male outer membrane grooves 202 are designed on the male outer membrane 2. Under the action of the number of male outer membrane grooves 202, the hand feeling will be more comfortable and not easy to slip; in addition, when inserting into the device, the force will also be more moderate and not laborious.

[0046] After the outer membrane is formed, the sealing ring 6 is sleeved into the sealing ring installation groove 502 of the male rubber core. This sealing ring 6 can ensure that there is no gap in the whole circumference of the contact area when inserted into the female head to achieve the purpose of waterproofing. To improve the reliability of the product insertion, a male rubber core hook 505 is also designed on the male rubber core 5. When the male rubber core hook 505 is inserted into the female head, it will hook the second card slot 1103 on the female rubber core 11 to ensure that the product is not easy to fall off during operation. When it is necessary to withdraw the male head from the female head, just press the male rubber core button 504 on the male rubber core 5 inward, and then the male rubber core hook 501 will disengage from the second card slot 1103 of the female rubber core under the elastic action of the male rubber core button 504 to achieve the purpose of separating from the male and female.

[0047] The female head is assembled according to the same process as the male head. First, the wire copper wires 102 are passed through the inner hole 901 of the heat shrinkable tube 9, and then the wire copper wires 102 are welded to the USB female head welding area 1001 of the USB female head 10. After welding, each heat shrinkable tube 9 is heated and shrunk. After shrinking, the heat shrinkable tube 9 will tightly wrap on the USB female head welding area 1001. This can effectively ensure that there is no short circuit phenomenon between each wire copper wire 102.

[0048] Then, the semi-finished product with the wire welded is inserted into the female rubber core jack 1101 of the female rubber core 11. After insertion, the entire product is placed into an injection mold for the molding of the female head inner membrane 8. The main purpose of molding the female head inner membrane 8 is to better protect the welding area. To enhance the adhesion between the female head inner membrane 8 and the female rubber core 11, several first card slots 1102 are designed on the female rubber core 11. When the female head inner membrane 8 is molded, the glue amount of the inner membrane will be injected into all empty places such as grooves through the pressure of the injection molding machine for filling. After filling is completed, the inner membrane molding of the female head inner membrane 8 is completed.

[0049] To further enhance the protection of the product, after the inner membrane of the female head inner membrane 8 is molded, the molded female head inner membrane 8 is placed into the outer membrane plastic mold for further molding. To ensure good adhesion between the female head inner membrane 8 and the female head outer membrane 7, several grooves 801 are also designed on the female head inner membrane 8. During the injection molding process of the female head outer membrane, the glue amount of the female head outer membrane 7 will also be injected into all empty places such as the grooves 801 of the female head inner membrane through the pressure of the injection molding machine for filling. When all the grooves 801 of the female head inner membrane are filled with glue, it will form a good wrapping with the female head outer membrane 7.

[0050] To protect the wire 1 from being easily broken, a wire clip 701 is also designed on the female head outer membrane 7. When the wire 1 sways due to external force, the wire clip 701 on the female head outer membrane 7 will bear and absorb most of the external force, thereby effectively protecting the wire 1 from being easily broken.

[0051] When the product is installed, the female head outer membrane 7 will be directly in contact with the bare hand. To improve the hand feeling and friction, several grooves 702 are also designed on the female head outer membrane 7. Under the action of several grooves 702 on the female head outer membrane, the hand feeling will be more comfortable and not easy to slip. In addition, when inserting into the device, the force will be relatively moderate and not laborious.
