Title:
PLATE-INSERT TYPE ULTRA-THIN KEY SWITCH
Document Type and Number:
WIPO Patent Application WO/2019/165854
Kind Code:
A1
Abstract:
A plate-insert type ultra-thin key switch, comprising a PCB (1), a base (2) provided on the PCB (1), a key cap (3) provided above the base (2), a guide core assembly (4) provided between the key cap (3) and the base (2), and a conduction assembly (5) inserted on the base (2). The conduction assembly (5) comprises a fixed piece (51) and a movable piece (52) which are provided corresponding to each other; pins (521, 511) are respectively provided at the lower ends of the movable piece (52) and the fixed piece (51); the pins (521, 511) are sequentially inserted into the base (2) and the PCB (1) from top to bottom, and penetrate to the lower end surface of the PCB (1) to be soldered on the lower end surface of the PCB (1). The plate-insert type ultra-thin key switch uses a plate-insert type soldering structure, so that the heat dissipation effect is greatly improved, without affecting the performance of the key switch; moreover, the performance requirements for a preparation material are reduced, i.e., a common material, instead of a high temperature-resistant material, is applicable, so that the material costs are lowered, the assembly expense is reduced, the assembly becomes more convenient and efficient, and automatic assembly is easily achieved.
