Abstract

The invention belongs to the technical field of keys of electronic products, and relates to a key structure, a manufacturing method and an electronic product, the key structure comprises a hard rubber shell, a soft rubber key, a switch and a PCB; the soft rubber key is arranged in the middle of the hard rubber shell, and the soft rubber key and the hard rubber shell are integrally formed through injection molding; the switch is arranged on the PCB and is positioned below the soft rubber key; the soft rubber key is made of TPU (thermoplastic polyurethane) materials, and the hard rubber shell is made of PC (polycarbonate) or PC + ABS (acrylonitrile butadiene styrene) materials, so that the soft rubber key is variable and convenient to press, the key structure is more compact and seamless, the reliability is better, dustproof and waterproof effects are achieved, the service life of an electronic product is effectively prolonged in application, and the overall appearance is more attractive and lighter.

Description

technical field [0001] The present invention relates to the technical field of buttons for electronic products, and in particular, to a button structure and a manufacturing method. Background technique [0002] With the development of science and technology, electronic products not only become more and more inseparable in daily life, but also become extremely important in the industrial world. The keyboard, as the input device of this electronic product, has become indispensable for inputting text, symbols or numbers. Therefore, the reliability requirements for the button structure are higher. [0003] At present, most of the electronic products on the market use hard plastic independent single-piece side buttons and main buttons, that is, the buttons and the shell are separated. Therefore, there are gaps in the traditional button structure and the structure is not compact enough. The reliability is not high, and its use is limited in environments that require dustproof and...
