Double-sided plug-in type micro USB B type male-socket connector

The invention discloses a double-sided plug-in type micro USB B type male-socket connector, which comprises a front iron shell, a back iron shell, an insulating film, a PCB, a main body board and contact terminals. The front iron shell and the back iron shell together enclose a cavity for accommodating the insulating film, the PCB, the main body board and the contact terminals. The main body board comprises an upper main body and a lower main body. The contact terminals comprise an upper terminal and a lower terminal. One end of the upper terminal is connected with the PCB, and the other end of the upper terminal is led out from the upper main body. One end of the lower terminal end is connected with the PCB, and the other end of the lower terminal is led out from the lower main body. The insulating film is clamped between the upper terminal and the lower terminal. The upper terminal and the lower terminal are in the form of copper 5-PIN elastic terminals that are stable in contact effect. After the 5-PIN elastic terminals are led into the front iron shell with the insulating film as an axis of symmetry, the front side and the back side of the front iron shell are the same in structure. According to the technical scheme of the invention, a B type male socket can be inserted into a female socket without the need of distinguishing the front and back sides of the B type male socket. Meanwhile, the short-circuit phenomenon is not easily formed between the contact terminals and the front iron shell, or between the upper terminal and the lower terminal. Therefore, the long-term usage of the B type male socket can be ensured.
