Embodiment Construction

[0086] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0087] First, explain the technical terms involved,

[0088] The printed circuit board, also known as a printed circuit board, a PCB circuit board, or a PCB (Printed Circuit Board) board, is a provider of electrical connections for electronic components. According to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. According to the distinction between soft and hard (flexible), it can be divided into rigid circuit boards, flexible circuit boards and soft-rigid combination boards. It is different from the bendable degree of the flexible circuit board.

[0089] The flexible printed circuit board is usually a...

Abstract

The invention provides an electrical switch structure adopting no metal dome and electronic equipment with the electrical switch structure. Inherent defects of a metal dome switch are overcome. The electrical switch structure comprises a rigid printed circuit board and a flexible circuit board. The rigid printed circuit board is opposite to the flexible circuit board. The rigid printed circuit board is provided with a first contact, the flexible circuit board is provided with a second contact, the first contact and the second contact are opposite and correspond to each other in position, and the first contact and the second contact are used as the two ends of a switch of the electrical switch structure respectively. Supporting posts are arranged between the rigid circuit board and the flexible circuit board. The two ends of each supporting post are connected with the rigid printed circuit board and the flexible circuit board respectively. The supporting posts are distributed around the first contact. A gap is reserved between the first contact and the second contact. When the portion, with the second contact, of the flexible circuit board is subjected to the pressure facing the first contact and exceeding the preset value, the first contact and the second contact make contact with each other and are connected.

Description

technical field [0001] The invention relates to the field of electrical components, in particular to an electrical switch used in a circuit board structure, and to electronic equipment using the electrical switch. Background technique [0002] Electrical switches are widely used in the internal circuit structure of electronic equipment, and their function is to control the conduction or disconnection of the circuits at both ends of the switch in the circuit. In order to make the circuit structure simple, and also to facilitate production, processing and assembly, an electrical switch structure with domes is widely used in existing printed circuit boards. [0003] Among them, domes (also known as metal dome or snap dome) are usually made of ultra-thin and ultra-hard stainless steel materials, and are mainly used in membrane switches, micro switches, PCB boards, printed circuit boards, rigid boards and other products. middle. It has the advantages of stable contact, strong c...
