[Knowledge of Skills] • In general electronic products, such as mobile phones, remote controls, and even general household appliances, for user input control The use of signal keys is quite common, and in order to make the keys not necessarily like computer mechanical keyboard keys, they have the disadvantages of complex structure and sound, usually using soft silicone rubber as the key material, as shown in the cross-sectional view of the first figure It is roughly that a silicon rubber sheet 1 is formed with a plurality of protruding keys ji at a time, so that the silicon rubber sheet j can be attached to a circuit substrate 2, and the bottom surface η of each key π and the circuit substrate 2 There is a gap 1 1 0 between them, and a bump 15 12 is formed on the bottom surface 1 1 1. When the top surface 112 of the key 11 is pressed, the bump 12 can be stressed by the key 丨 丨And contacting the circuit board 2 downwards, and then the relatively designed electrical-circuit contacts on the circuit board 2 are turned on to generate an electronic signal. However, the keys 11 made of silicone rubber are quite soft and easy to grind, because The top surface 112 of the key 11 is often pressed by the user 20, so it will be the most severely worn. In order to improve this disadvantage, there is a slightly higher hardness plastic material on the top surface n2 of the silicone rubber key. It is formed on a contact layer 13 with a higher hardness contact layer for the user to press to extend the life of the button.

Description of the invention (2) Press the button 1 At 1 o'clock, the contact point between the finger and the button 11 is not at the center of the top surface 112 of the button 11, but there are more opportunities at the top edge 1 121. Therefore, although a contact layer 13 is formed on the top surface U2 The user's finger touches and presses, but the top edge 丨 丨 2 丨 and the side of the key 丨 丨 will still be rubbed by the user's finger, so the key 丨 丨 wear will be concentrated on the top edge π of the key π Therefore, the method of directly forming the contact layer 13 on the top surface 1 1 2 of the button 对于 is not very satisfactory for enhancing the anti-wear effect of the button 11. [Summary of the Invention] 10 Therefore, the main object of the present invention is to provide a method for strengthening a silicone rubber key, which can effectively avoid deformation and abrasion of the top surface and the top edge of the key. Therefore, the method of strengthening the silicon rubber key of the present invention is mainly to form a plastic film cover that can cover the top surface of the key and the edge of the top surface in accordance with the shape of the top surface of the key, so that the film cover is provided with a The top surface of the key top 15 and the inner surface where the top surface edge contacts. After coating a certain amount of hardener on the inner surface of the film cover body, the film cover body covers the top surface of the key and the top surface edge for the user to press The contact, and the film cover which is hardened by the hardener to increase the hardness can enhance the characteristics of the top surface of the key to resist deformation and abrasion. 20 [Simplified description of the drawings] Other features and advantages of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings.

The third figure is a schematic sectional view of a combination of a silicon rubber key and a film cover in the preferred embodiment. [Detailed description of the preferred embodiment] Please refer to the second figure 'A preferred embodiment of the method of strengthening the silicone rubber key of the present invention is applied to a soft silicone rubber key, and as shown in the figure, in this example' The Shixi rubber button 31 is integrally formed on a silicon rubber sheet body 3. The method of the present invention is mainly as follows: First, a corresponding film cover 41 is formed to match the shape of the top surface 3 丨 of each key 3 丨. In this example, a plurality of film covers 4 丨 are used with a relatively thin thickness. The plastic film 4 is integrally hot-pressed. Each of the film covers 41 has an inner surface 411 that can cover the top surface 311 of the opposite key 31 and the edge of the top surface. Then, a certain amount of hardener is applied to the inner surface 4 1 1 of the film cover body 41. In this embodiment, epoxy resin is used as the main hardener component, and the inner surface of the hardener can be formed on the inner surface of the hardener when it is dry. The higher hardness of the hardened layer 4 1 2 further increases the structural strength of the film cover 41. Next, after the hardener is completely dried or hardened, or the hardener is not yet dried, the inner surface 41 1 of the film cover 41 coated with the hardener may be covered with relative knowledge: the top surface of the key 3 1 3 1 1 And its top edge, the film cover 4 with increased hardness is formed by hardening the hardened layer 4 1 2 with a hardening agent, which can replace the top surface 3 1 1 of the opposite key 3 1 to accept the user's pressing, so that it can be enhanced Relative knowledge: the top surface 3 1 1 of the key 3 1 and its top surface resist deformation and abrasion.
