Embodiment Construction

[0016] The specific embodiments and examples of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.

[0017] A method for making a keypad for a mobile phone according to the present invention, one of its specific implementations, includes the following steps: firstly fix the conductive base part of the keypad on a PET (polyester terephthalate, poly pair) ethylene glycol phthalate) sheet; at the same time, the keycap of the button is also fixed on a TPU film through UV transfer printing process; then the conductive base and the PET sheet are cut according to the size of the button area, so that The key made has elasticity; then a TPU (Thermoplastic polyurethanes, thermoplastic polyurethane) film with a key cap is arranged on the PET sheet.

Abstract

The invention discloses a mobile phone key and a manufacturing method thereof. The mobile phone key comprises a key conductive base and a key cap, wherein the conductive base can be arranged on a PET (polyethylene terephthalate) sheet via UV (ultraviolet) transfer print; the key cap can be arranged on a TPU (thermoplastic urethane) film via UV transfer print; the TPU film is arranged on the PET sheet; corresponding trim lines which are used to divide the key region sizes are respectively arranged on the PET sheet and the conductive base so that the manufactured key has the elasticity. As adopting the technical means, namely, the key conductive base can be arranged on the PET sheet via the UV transfer print and is trimmed so that the manufactured key has the elasticity; meanwhile, the thinner PET sheet can be utilized to replace the thicker elastic arm in the existing mobile phone key, thus the overall height of the mobile phone key can be greatly decreased and the development tendency of ultrathin mobile phones nowadays can be satisfied. Therefore, the key provided by the invention is very suitable for being used on the flip phone and / or slide phone with limited space.

Description

technical field [0001] The invention relates to the field of mobile phones with keyboards, and more specifically, the improvement relates to a mobile phone key and a manufacturing method thereof. Background technique [0002] Existing mobile phone keys usually include keycaps and conductive bases; keycaps are generally made of hard rubber, silicone or UV transfer keycaps; conductive bases are generally made of soft rubber, including at least 0.3mm thick elastic arm parts and 0.3mm thick The last part of the conductive base layer makes the overall height of the conductive base reach more than 0.6 mm. [0003] However, with the current development trend of mobile phones towards ultra-thin direction, the structure of existing mobile phone buttons has become more and more difficult to realize on flip phones and / or slider phones with limited space. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0005] The object of the ...
