Abstract

The invention relates to a peripheral device including a user operation interface, a carrier board and a circuit board. The bearing plate bears the user operation interface, wherein the bearing plate has a side of the bearing plate, which extends substantially along the X-axis, and the side of the bearing plate is provided with a left concave area of ​​the bearing plate, a left convex arc edge, and a central straight edge in sequence. , the right convex arc edge and the right concave area of ​​the bearing plate. The circuit board has a body part and a flexible extension part, wherein the body part is used to generate an operation signal in response to the user operation interface being triggered, the flexible extension part substantially extends along the Y axis, and the flexible extension part has an upper end, a lower end, a Y The left side of the axis and the right side of the Y-axis, the upper end of the flexible extension part is connected with the main body, the lower end of the flexible extension part can be connected with the external contact, and the operation signal is transmitted to the external contact through the flexible extension part. A left convex arc edge and a right convex arc edge are provided on the side of the carrier board to avoid the problem that the flexible extension part of the circuit board is cut and damaged by the sharp side of the carrier board due to bending.

Description

technical field [0001] The present invention relates to an electronic device, in particular to a peripheral device. Background technique [0002] Advances in information technology have brought more convenience to people's lives, so tablets, smartphones or laptops are becoming more and more popular. These information products all have built-in peripheral devices for user operation and input, such as touch panels, keyboards or touchpads; however, for the convenience of assembly, disassembly and maintenance, these peripheral devices are generally The flexible circuit board is electrically connected to the connector in the information product, so that the data signal input by the user to the peripheral device is transmitted to the portable information product through the flexible circuit board. [0003] Please refer to figure 1 and figure 2 . figure 1 A perspective view of a conventional peripheral device is shown. figure 2 drawn according to figure 1 The schematic diag...

Problems solved by technology

When the flexible extension 34 of the circuit board 30 is bent and pulled by an external force, the stress point is concentrated on the intersection point of the side 34a of the flexible extension 34 and the side 20a of the supporting board 20, which may easily lead to damage. The flexible extension part 34 is cut by the sharp side 20a of the carrier board 20 and is broken and damaged, causing the internal wires of the circuit board 30 to break, resulting in poor electrical conduction or signal transmission of the peripheral device 10
