Embodiment Construction

[0014] see figure 1 , which is a schematic diagram of the electronic device in this embodiment, and please refer to figure 2 ,for figure 1 The partial cross-sectional enlarged view of the electronic device is shown, wherein the button 200 can be used in the electronic device 100 , and the electronic device 100 includes the upper casing 11 , the lower casing 12 and the button 200 . A pressing portion 13 is formed on the outer surface of the upper case 11 . In this embodiment, the upper case 11 defines a through hole, and an elastic material is poured into the through hole to form the pressing portion 13 integrated with the upper case 11 . The button 200 is installed in the electronic device 100 through the circuit board 21 fixed with the lower casing 12 , and in this embodiment, the fixing method may be bonding, screwing or welding. The position of the key 200 corresponds to the position of the pressing part 13 , and the key structure 200 is triggered by pressing the pressin...

Abstract

The invention relates to a key comprising a circuit board and a spring plate, wherein the circuit board comprises tact switches which are arranged on the circuit board, are electrically connected with the circuit board and are used for switching on the key; and the spring plate comprises a fixed part, a connecting part, contacting parts and contacts, wherein the fixed part is fixed on the circuit board, the connecting part is respectively fixedly connected with both sides of the fixed part and is inclined upwards, the contacting parts are arranged on both ends of the connecting part and are tilted, and the contacts are arranged on one side of the contacting part near the circuit board and respectively correspond to the tact switches. The key leaves out the flexible rubber key body and the hard rubber key top of the traditional key, switches on the contacts and the tact switches only through contacting the spring plate to realize the key function, and has the advantages of easy assembly and small size.

Description

technical field [0001] The invention relates to a key and electronic equipment using the key. Background technique [0002] With the advancement of portable electronic products, in addition to meeting the performance requirements, the electronic products are also more and more fashionable and beautiful, and the size is also made smaller and thinner. The man-machine interface, such as buttons, is also required to become more and more fashionable, lighter and thinner. [0003] The button structure of the existing electronic equipment includes a soft rubber key body made of soft silicone and a PCB board carrying the soft rubber key body, and a hard rubber key top made of hard plastic is set on the soft rubber key body. The key tops protrude from the housing. A switch positioning point is set at the bottom of the soft rubber key body, and a tact switch is provided on the PCB board. In this way, the user presses the key top to deform the soft rubber key body, and the switch po...
