In this embodiment, since the connection plug 51, the fixing panel 52 and the fixing seat 53 are manufactured by integral injection molding, the connection between them is more secure and has higher strength and stability. Integral injection molding can reduce material waste because it can complete the manufacture of multiple parts in a single injection molding process, avoiding additional processing and assembly steps.

[0060] A mounting seal ring 521 is provided on one side of the fixed panel 52, and the fixed panel 52 is provided with a fixed mounting hole 522, and the fixed mounting hole 522 is used to pass a screw to fix and install the fixed panel 52. In this embodiment, the mounting seal ring 521 is an annular sealing element, which is usually made of materials such as rubber or silicone. It is installed on one side of the fixed panel 52 to provide a sealing effect to prevent dust, moisture or other impurities from entering the interior of the connector or device, thereby protecting the performance and reliability of the connector or device. The fixed mounting hole 522 is a hole for passing a screw, which is provided on the fixed panel 52. By passing the screw through the fixed mounting hole 522 and tightening it, the fixed panel 52 can be firmly fixed at the position where it needs to be installed. Such a design makes the installation of the fixed panel 52 more convenient and quick, and can provide a stable fixing effect.

[0061] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
