In a specific embodiment provided by the present invention, the USB connector mainly includes a shell 1, a rubber core 2, a terminal 3 and a rear plug 4, the terminal 3 is inserted into the installation groove of the rubber core 2, and the rear plug 4 is inserted into the installation groove of the rubber core 2. Connected to the end of the rubber core 2, the rubber core 2 is clamped in the shell 1, and the end of the shell 1 is provided with a first connecting pin 5 for plug connection and a second connecting pin 6 for bending connection in the circumferential direction.

Among them, the terminal 3 is inserted into the installation slot of the rubber core 2, and the terminal 3 is used for interface connection with external equipment; the rubber core 2 is used to fix the terminal 3 in the installation slot; The core 2 is snapped into the casing 1, and the rear plug 4 is used to isolate the internal circuit of the connector from the outside air environment; The second connection pin 6, the first connection pin 5 is used for connecting the USB connector with an external first device, and the second connection pin 6 is used for connecting with an external second device.

Specifically, in the actual installation process, the terminal 3 is integrally formed and embedded in the plastic, and inserted into the installation groove of the plastic core 2 to make a semi-finished product including the terminal 3, and then the semi-finished product and the rear plug 4 are formed. Assembling, the effect of isolating the internal circuit of the connector from the external air environment is formed by the rear plug 4, which can play a very good waterproof effect; finally, the semi-finished product is assembled with the shell 1, and the installation of the USB connector can be completed; In the actual use process, plug the first connecting pin 5 with the first external device, and weld the first connecting pin 5 and the first external device. If there is further demand, connect the second connecting pin 6 with the first external device. The two external devices are plugged, and the second connecting pin 6 and the second external device are welded to complete the use of the USB connector.

In order to optimize the advantage that the USB connector in the above embodiment can perform secondary connection of external devices, the length of the first connection pin 5 is smaller than the length of the second connection pin 6 .
