FPC connection structure and terminal

Abstract

The embodiment of the invention relates to the field of connection structures and terminals, in particular to a FPC connection structure and a terminal. Thus, through simple structure connection, grounding of a flexible printed circuit FPC is achieved and grounding of an acoustic device is achieved. In the embodiment of the invention, the FPC connection structure comprises a first contact and a second contact. The first contact is connected with a spring sheet which is conducted with a grounding wire on a main board FCB. The second contact is connected with the acoustic device. The first contact and the second contact are arranged on the FPC which is used for conducting the first contact and the second contact. According to the invention, the first contact is connected with the spring sheet of the grounding wire, and the second contact is connected with the first contact and the acoustic device, so through the simple structure connection, grounding of the flexible printed circuit FPC is achieved and grounding of the acoustic device is also achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of connection structures and terminals, in particular to an FPC connection structure and terminals. Background technique [0002] With the development of technology, the requirements for the terminal structure are getting higher and higher. At present, the design of mobile terminals such as mobile phones requires the use of acoustic devices, such as speakers, earpieces, microphones (MIC for short), flexible printed circuit boards (FPC for short), and printed circuit boards (PCB for short). [0003] The grounding requirements for acoustic devices such as speakers, earpieces, and microphones (MIC) are extremely high in the clearance area of ​​the terminal's antenna. This is because the acoustic devices are metal devices with magnetic coils inside. If the acoustic components such as speakers, receivers, and microphones are not properly grounded, it will affect the performance of the speakers, recei...

Problems solved by technology

If the acoustic components such as speakers, receivers, and microphones are not properly grounded, it will affect the performance of the speakers, receivers, microphones and other acoustic components on the terminal, as well as the performance of the antenna on the terminal. Download technical test (Over The Air referred to as OTA) indicators; it will also affect the image sensor sensor test of the terminal

Moreover, if the acoustic device fails to handle the grounding properly, there will be conflicts between the operation and storage of the acoustic device. For example, if the speaker fails to handle the grounding properly, there will be a conflict with the storage when the speaker is placed outside.

[0004] In the prior art, the grounding of the speakers, earpieces, and microphones requires an independent grounding scheme to achieve grounding, and the scheme is very complicated; especially, when the speakers, earpieces, and microphones are placed in an all-plastic shell, it is difficult to achieve grounding
