Example Embodiment

[0033] Refer to figure 2 The schematic diagram of the side key device of the embodiment of the present invention. The embodiment of the present invention takes the application of the device to a mobile communication device such as a mobile phone as an example for description but is not limited to this. Such as figure 2 Shown, including:

[0034] Case 11, side keys 12, shrapnel Dome13, FPC14, bracket reinforcement 15, PCB16, LCD 18.

[0035] The case 11 is the exterior part of the mobile phone and is used to protect the internal parts. The side key 12 is a moving part, which triggers the Dome 13 after the force movement reaches a certain stroke. Dome 13, deforms after being stressed, triggering a hardware signal. FPC14, as a flexible circuit board, transmits hardware signals. One side of the FPC 14 is connected with the dome 13 to receive the force of the side key, and the other side is connected with the support reinforcement 15. The support reinforcement 15 is used as a sup...

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 reinforcing device, a bracket reinforcing part 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 as the base material, 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 bu...
