The structure is simple and easy to disassemble and assemble. The housing 10 is cleverly set into two insertion cavities, replacing the method of splicing multiple USB connectors. In addition, the terminal pins 22 are covered with a waterproof cover 90 so that the terminal pins 22 are received in the insertion cavity, which can effectively prevent external water vapor from entering the insertion cavity, and has a higher waterproof level.

[0038] In a possible implementation, both sides of the waterproof cover 90 are bent to form folded edges 90a, and a snap-in slot is provided on the folded edges 90a. A block 100 adapted to the snap-in slot is provided on the side of the housing 10 so that the waterproof cover 90 can be detachably connected to the housing 10.

[0039] Exemplarily, by bending the two sides of the waterproof cover 90 to form a folded edge 90a, and opening a snap-in slot on the folded edge 90a, and then cooperating with a block 100 set on the side of the outer shell 10, the waterproof cover 90 can be detachably installed on the outer shell 10, with a simple structure and easy disassembly and assembly.

[0040] In a possible implementation, the surface of the waterproof cover 90 facing away from the housing 10 is provided with a first stopper 200 and a second stopper 300, respectively, a limit zone is formed between the first stopper 200 and the second stopper 300, and the terminal pin 22 is located in the limit zone. In this way, the limit zone is formed by using the first stopper 200 and the second stopper 300 provided on the waterproof cover 90, so that the terminal pin 22 can be better connected to the external circuit board.

[0041] In a possible embodiment, the upper inner wall and the lower inner wall of the insertion cavity are respectively provided with a first elastic arm 40 and a second elastic arm 80, and the first elastic arm 40 extends to the insertion port at one end to form a first abutment portion 40a, and the second elastic arm 80 extends to the insertion port at one end to form a second abutment portion, and both the first abutment portion 40a and the second abutment portion protrude toward the direction of the supporting seat 21.

[0042] Exemplarily, when the connector is inserted from the insertion port into the insertion cavity to be connected with the supporting seat 21, the upper and lower surfaces of the connector are in contact with the first abutment portion 40a and the second abutment portion respectively, so that a clamping force can be applied to the surface of the connector, thereby strengthening the fixed connection between the connector and the housing 10 and effectively avoiding shaking or falling off during the plug-in process.

[0043] In a possible embodiment, the first elastic arm 40 and the second elastic arm 80 both include an integrally formed straight section 41 and a curved section 24 , the curved section 24 is bent away from the supporting seat 21 , and a first abutment portion 40a or a second abutment portion is formed between the curved section 24 and the straight section 41 .

[0044] In a possible implementation, a first mounting column 50 and a second mounting column 60 extending along the width direction of the housing 10 are respectively disposed on both sides of the mounting frame 30, and the first mounting column 50 and the second mounting column 60 are alternately disposed. The first mounting column 50 and the second mounting column 60 are both provided with fixing holes 70 for fixing.

[0045] Exemplarily, by setting a first mounting column 50 and a second mounting column 60 extending along the width direction of the outer shell 10 on both sides of the mounting frame 30, and opening a fixing hole 70 on the first mounting column 50 and the second mounting column 60, and then using a fastener to pass through the fixing hole 70 to fix the outer shell 10, the structure is simple and easy to disassemble and assemble.

[0046] In order to further enhance the waterproof performance of the USB connector, in a possible implementation, the through-hole is provided with waterproof glue in contact with the terminal pin 22 , so as to effectively prevent external water vapor from penetrating through the gap between the through-hole and the terminal pin 22 .
