Detailed ways

The concrete structure in the utility model is described below in conjunction with accompanying drawing of description:

A kind of double USB interface socket, as shown in Figure 1 to Figure 6, it comprises the shell that is formed by the connection of front shell 1 and rear shell 2, and the circuit board module 3 that is contained in the described shell, and described circuit board module 3 are fixed with two parallel USB interfaces 31, two rectangular sockets 11 aligned with the two USB interfaces 31 are formed on the front shell 1, and the inner wall of the front shell 1 is formed with rectangular The socket 11 is provided with a square ring-shaped protrusion 12, the square ring-shaped protrusion 12 has an inner hole 13 matching the USB interface 31, and the inside of the square ring-shaped protrusion 12 is formed with a The resisting surface 14 is formed with several supporting bosses 21 on the inner wall of the rear shell 2, the circuit board module 3 is supported on the plurality of supporting bosses 21, and the USB interface 31 extends into the The front end of the USB interface 31 inside the square annular protrusion 12 abuts against the resisting surface 14 . With the above structure, when assembling the product, the circuit board module 3 is loaded into the rear case 2 and supported by the support boss 21, the USB interface on the circuit board module 3 faces the direction of the front case 1, and then the front case 1 is connected with the rear shell 2, so that the USB interface 31 is inserted into the inner hole 13 of the square annular protrusion 12, and the circuit board module 3 is supported because the front end of the USB interface 31 is against the resisting surface 14 of the inner hole 13 The boss 21 cooperates with the resisting surface 14, so that it can be reliably installed in the housing, and the operation is convenient, which can effectively improve work efficiency.
