Problems solved by technology

[0007] However, at present, the battery life of mobile terminals and smart terminals is insufficient. With the development of mobile Internet and the increasing number of emerging consumer electronics such as Android, pad, and MID, consumers use mobile terminals to connect to the network more and more times and for a long time. Work will inevitably lead to more and more micro-USB port charging times
At present, some terminals with micro-USB interface are loose after being plugged and unplugged many times. After loosening, the USB_D-, USB_D+, VCC_5V, and GND signal lines are disconnected or poorly connected, resulting in users being unable to charge and transmit data.

Embodiment Construction

[0037] This implementation mode provides a micro-USB interface structure, which is used to realize the stability as a charging interface and a data transmission interface, and specifically adopts the following technical solutions:

[0038] The micro-USB interface structure is composed of two parts: a general-purpose micro-USB interface and a shielding case (micro-USB shielding cover, also referred to as a shielding cover in the text) covering it, and the shielding case is closely attached to the micro-USB port. On the cover above, the two are mounted together on the circuit board.

[0039] Preferably, a miniature shielding case is used and placed on the micro-USB interface. When soldering, it is close to the surface of the micro-USB interface and fixed on all four legs to achieve the firmness of the interface and ensure the charging interface and data transmission. The interface works stably.

[0040] Preferably, an in-line shielding case can also be used, and the in-line shi...

Abstract

The invention discloses a micro-USB interface structure, a device and a mobile terminal. The micro-USB interface structure comprises a micro-USB interface and a shielding cover which covers on the micro-USB interface; and both the shielding cover and the micro-USB interface are fixedly connected to the circuit board. As the micro-USB interface structure, disclosed by the invention, is adopted, plugging and unplugging impact under various conditions can be borne and stability of the micro-USB interface can be kept.

Description

technical field [0001] The invention relates to the technical field of communication terminals, in particular to a micro-USB interface structure, device and mobile terminal. Background technique [0002] In January 2007, the USB-implementers Forum (USB Application Manufacturers Forum) officially announced a new generation of USB connector specifications: micro-USB (micro USB) connector (plug and receptacle). In 2009, the European Union passed the mobile phone charger standard, the most important feature of which is: uniform use of the micro-USB interface. As more and more well-known phone manufacturers participate in and sign the EU agreement, micro-USB ports are more and more widely used in the terminal field. [0003] The micro-USB interface connector has the following advantages compared with the general USB port connector: [0004] 1. Strong resistance to plugging and unplugging test: Under the condition of maximum impact test under the same conditions, ordinary USB po...
