Problems solved by technology

[0003] However, the existing structure takes up a relatively large space, especially when the side keys are located on the left and right sides of the mobile phone, it often becomes the main bottleneck of the mobile phone width, which conflicts with the increasingly thinner and lighter mobile phones.

Embodiment Construction

[0028] refer to figure 2 A schematic diagram of a side key device according to an embodiment of the present invention. Embodiments of the present invention are described by taking the device applied to mobile communication equipment such as mobile phones as an example, but not limited thereto. Such as figure 2 shown, including:

[0029] Case 11, side key 12, shrapnel Dome13, FPC14, bracket reinforcement 15, PCB16, LCD18.

[0030] The casing 11 is an exterior part of the mobile phone and is used to protect internal parts. The side key 12 is a moving part, which triggers the Dome 13 after the force movement reaches a certain stroke. Dome13 will deform after being stressed, triggering a hardware signal. FPC14, as a flexible circuit board, transmits hardware signals. One side of the FPC 14 is connected to the elastic piece Dome 13 to receive the force of the side key, and the other side is connected to the bracket reinforcement 15 . The bracket reinforcement 15 is used as...

Abstract

The invention discloses a support reinforcing device, a support reinforcing piece and a side key device. The support reinforcing device comprises a flexible printed circuit (FPC) and the support reinforcing piece. One face of the FPC is connected with an elastic sheet Dome to receive side key stress, and the other face of the FPC is connected with the support reinforcing piece. The support reinforcing piece is separated from a casing and comprises a first component and a second component. The first component and the second component are of an integrated structure. The first component of the support reinforcing piece is connected with one face of the FPC to support stress of the FPC, and the second component of the support reinforcing piece is connected with a main board printed circuit board (PCB) to support a main board. By means of the method, the technical scheme can reduce occupied space and meet requirements of current increasingly light and thin communication devices.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a bracket reinforcement device and a side key device. Background technique [0002] At present, in the design of mobile communication devices such as mobile phones, the side key is also a component that cannot be ignored. Said side key can be, for example, a volume key, a camera key, a power key, and the like. The side button FPC (Flexible Printed Circuit, flexible circuit board) generally uses stainless steel or hard PI (polyimide) as a reinforcement board. FPC is a highly reliable flexible printed circuit board made of polyimide or polyester film, also known as soft board, and PCB (Printed Circuit Board, printed circuit board) can generally be called hard Board. The role of the reinforcing plate is generally to strengthen the force. The FPC and shrapnel Dome are pasted on the reinforcing plate to ensure the button feel. At the same time, a supporting rib i...
