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

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of double-sided USB male plugs, in particular to a double-sided MicroUSBB male connector. Background technique [0002] The power plug connector and the power socket connector are two connectors that are mated with each other to complete power transmission or data transmission. The power plug connector is widely used on mobile phone data lines to charge mobile phones or export and import data. . [0003] The tongue plate of the current standard power socket connector is a plastic body integrally formed on the insulating body, the distance between the upper surface of the tongue plate and the upper inner wall of the shielding shell and the distance between the lower surface of the tongue plate and the lower inner wall of the shielding shell are not the same. However, the tongue plate of the current power plug connector also extends integrally from the insulating body, and the tongue plate of the power plug ...

Problems solved by technology

[0005] However, this utility model cannot effectively avoid the problem of short circuit between the terminal and the iron shell when the user is using it. At the same time, the bump design of the iron shell of the connector is also likely to lead to unstable contact, so there are still problems with the safety of the utility model.
