Problems solved by technology
[0002] The use conditions of the detection instrument are generally exposed, and are often exposed to various extreme conditions, such as high temperature, strong acid, and strong alkali environment. At the same time, due to the high cost of detection, it cannot be replaced frequently. Therefore, the keyboard of the instrument is used for a long time , high frequency, severe wear or loss
[0003] The keyboard of the detection instrument is generally made of silica gel. The existing contacts are small circular contacts formed of conductive silica gel. As time increases, the contacts will have poor contact and affect the performance of the instrument. Normal use

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0017] An instrument keyboard with good resilience, such as figure 1 As shown, it includes a silicone keyboard membrane 3 and a silicone button 1, and an installation socket 2 is formed on the edge of the silicone keyboard membrane.
[0018] The key array is integrated on the upper surface of the keyboard membrane, and the distribution of the key areas is as follows: the keyboard on the silicone keyboard film is composed of two interlaced key areas I and II, and the I area is the direction key indication area, including four directions The selection key and four menu keys also include two larger function keys up and down. Area II is the number key area, which consists of four rows of 12 keys arranged...

The invention relates to an instrument keyboard having great resilience. The instrument keyboard comprises a silicone keyboard film and silicone keys. An installing jack is manufactured at the edge of the silicone keyboard film. The keys are integrally manufactured on the upper surface of the keyboard film in an array way. The keys are keys of which the bottom parts are provided with grooves. Contact columns are manufactured at the center parts of the key grooves. An insulating layer is adhered on the bottom part of the silicone keyboard film in a parallel way. A wearing layer is adhered on the lower part of the insulating layer in the parallel way. Steel conductive elastic sheets are adhered on the positions, which are corresponding to the contact columns, of the lower surface of the wearing layer. Holes of the shape of the conductive elastic sheets are manufactured on the insulating layer of the top part of the conductive elastic sheets. According to the instrument keyboard having great resilience, the existing electrically conductive silicone contacts are changed, and contacting is performed by using the mode of the metal elastic sheets so that the contact area is increased; meanwhile, the resilience of the metal elastic sheets is great so that the instrument is ensured to be sensitive and the service time of the keyboard can also be effectively increased.
Description
technical field [0001] The invention belongs to the field of detection instruments, in particular to an instrument keyboard with good resilience. Background technique [0002] The use conditions of the detection instrument are generally exposed, and are often exposed to various extreme conditions, such as high temperature, strong acid, and strong alkali environment. At the same time, due to the high cost of detection, it cannot be replaced frequently. Therefore, the keyboard of the instrument is used for a long time , high frequency, serious wear or loss. [0003] The keyboard of the detection instrument is generally made of silica gel. The existing contacts are small circular contacts formed of conductive silica gel. As time increases, the contacts will have poor contact and affect the performance of the instrument. Normal use. Contents of the invention [0004] The object of the present invention is to overcome the disadvantages of the prior art and provide an instrume...
