It is a new interface developed by the USB standardization organization to solve the long-standing shortcomings of USB interfaces such as inconsistent physical interface specifications and one-way power transmission. It integrates charging, display, data transmission and other functions in one. It has fast transmission speed, small size, and can be inserted in both directions, so it is likely to be widely used in electronic products.

[0004] The existing type C connector structure has been greatly improved in terms of overall structure and plug-in and unplugging smoothness. For example, the design of the internal pins has been improved, which has improved the force uniformity during the plug-in and unplugging process. However, there are still many shortcomings, such as the problem of loose components during the plug-in and unplugging process, which is to a certain extent attributed to the design of the internal structure.

[0005] For example, the utility model patent with application number 202122036447.2 and patent name "A type-c connector easy to fix" specifically discloses a type-c connector that is easy to fix, including a shell, a plug, a base and a fixing part. The plug is sleeved on one end of the base, the shell is sleeved on the outer end of the plug, and the fixing part is installed on the outer end of the shell. Support blocks are provided at both ends of the front of the plug, the plug is provided with a number of terminals, a card slot is provided at the front end of the plug, the support block is provided with a card block, the support block and the plug are detachably connected, the shell is provided with a buckle position, the base is provided with a fastener used in conjunction with the buckle position, and limiting slots are provided at both ends of the plug; the fixing part includes an upper cover and a bottom shell, the upper cover is installed on the upper end of the bottom shell, the shell is provided with a through slot, and the upper cover is provided with a protrusion. The support block is inserted into both ends of the plug. When docking the type-c male connector, it can support the type-c male connector from the inside. The protrusion of the upper cover can fix the type-c male connector externally after insertion, thereby further fixing the type-c connector and preventing it from loosening.
