Assembling push key

Abstract

The invention discloses a modular push-button on the base of electronic device, wherein the base possesses at least triggering part and first connecting part near to the triggering part; modular push-button contains button bulk, triggering part and second connecting part; the second connecting part is set on the back of button, which can be set on the first connecting part detachably.

Description

technical field [0001] The invention relates to an assembled key, in particular to an assembled key used in an electronic device. Background technique [0002] Since Philips of the Netherlands and Sony of Japan jointly published the Red Book in 1982 and formulated the compact disk (CD) specification, the music disc (Compact Disk Digital Audio, CD-DA) It became the ancestor of optical drive series products. Later, with the development of computer technology, the popularity of multimedia, and the publication of specifications such as Yellow Book, Green Book, Orange Book, and White Paper, CDs have a wider range of applications in data storage. [0003] Due to the increasing scope of multimedia applications and the increasing requirements of users for video and audio effects, in 1996, Philips of the Netherlands, Sony Corporation of Japan and Toshiba of Japan reached an agreement and cooperated with other manufacturers Jointly proposed the digital versatile disc (Digital Versat...

Problems solved by technology

[0008] However, this existing button is thermally welded on the upper cover of the device, and the labor cost required for thermal fusion is quite high, so the manufacturing cost is relatively increased.

Moreover, the process of hot-melting is complex and difficult to quantify, and the control of position accuracy is difficult, which makes the manufacturing process complicated and is not conducive to manufacturing

[0009] At the same time, the button on the upper cover of the device is not directly connected to the substrate by using this prior art. When the position of the thermal fusion is slightly deviated or not correct, the trigger part of the substrate cannot be actuated. It takes force to produce an effect, and even the trigger part cannot be activated at all, which reduces the good rate of the product

Moreover, under long-term use, the substrate in the device may become loose or displaced due to transportation or collision, resulting in the problem of inability to operate reliably.

[0010] In addition, because this prior art is bonded by heat fusion, the buttons after bonding are integrally integrated on the upper cover of the device. When it is found that the position of the heat fusion is deviated, the substrate is loose or displaced, the trigger part of the substrate cannot be actuated, or If the button itself is damaged or the material is fatigued, or the joint between the button and the upper cover is damaged, the entire upper cover must be scrapped, and then a new upper cover must be replaced, and operations such as locking the substrate and hot-melting the buttons must be performed again.

In this way, not only is it not conducive to maintenance, but these repetitive tasks greatly increase the cost
