Description

A new type of key board

[technical field]

The utility model relates to a novel key board.

[Background technique]

Traditionally used in key boards of electronic weighing instruments such as electronic case scales and electronic platform scales, the silicone protective sleeve is fixed under the panel by screws, and a layer of PET film with printed key fonts is pasted on the panel. The disadvantage is that the PET film The life of the sheet is short, and it is very easy to be damaged. At the same time, the key fonts silk-screened on the PET film are very easy to fall off, making the user unclear about the function of the key.

[utility model content]

The utility model overcomes the deficiencies of the above-mentioned technologies, and provides a new type of key board. By pasting and connecting metal sheets engraved with key fonts on the convex key part of the protective cover layer, the service life of the protective cover layer is prolonged and the key fonts are prevented from falling. .

In order to achieve the above object, the utility model adopts the following technical solutions:

A new type of keypad, including a panel 1, a through hole 2 is provided on the panel 1, a flexible protective sheath layer 3 is connected to the panel 1, and a protrusion passing through the through hole 2 is provided on the protective sheath layer 3. The key portion 4, the bottom of the protective sheath layer 3 is connected with an electronic board 5, the electronic board 5 is provided with an electronic button 6 sleeved in the convex key portion 4, and the top of the protective sheath layer 3 is provided with a metal sheet 7 , the metal sheet 7 is provided with key fonts.

The electronic board 5 is provided with an LED light 8 that works when the electronic button 6 is pressed.

The LED lamp 8 is arranged on the side of the electronic button 6 .

The protective sheath layer 3 is made of silica gel or rubber.

The protective sheath layer 3 is adhesively connected with the metal sheet 7 .

The key characters are etched or stamped on the metal sheet 7 .

The panel 1 and the electronic board 5 are connected by screws.

The beneficial effects of the utility model are:

The utility model pastes and connects a metal sheet with a button font on the convex key part of the protective cover layer, and the metal sheet can better trigger the electronic button, which is beneficial to prolong the service life of the protective cover layer, and at the same time, the etched font on the metal sheet It will not fall off, and at the same time, a patch LED light is added to the electronic board. When the button is pressed, the LED light will glow along with the button, giving users a new experience.

[detailed description]

Below in conjunction with accompanying drawing and embodiment of the present utility model, further describe in detail:

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a new keypad includes a panel 1, the panel 1 is provided with a through hole 2, and the panel 1 is connected with a flexible protective sheath layer 3, so The protective sheath layer 3 is provided with a convex key portion 4 passing through the through hole 2, and the bottom of the protective sheath layer 3 is connected with an electronic board 5, and the electronic board 5 is provided with an electronic device sleeved in the convex key portion 4. The key 6, the convex key part 4 plays the role of protecting the electronic key 6, the top of the protective cover layer 3 is provided with a metal sheet 7, the metal sheet 7 is provided with a key font, and the key font is etched or stamped on the On the metal sheet 7, the metal sheet 7 improves the accuracy of pressing the electronic button 6 by the user, and the metal sheet 7 better protects the protective cover layer 3 and effectively prevents the key font from falling off.

Wherein, as shown in Figures 2 and 4, the electronic board 5 is provided with an LED light 8 that works when the electronic key 6 is pressed, and the LED light 8 is arranged on the side of the electronic key 6. When the key is pressed, the LED light 8 The light shines along with the button, giving the user a brand new experience.

The protective sheath layer 3 is made of silica gel or rubber, which better protects the electronic key 6 and avoids damage caused by pressing the electronic key 6 directly.

The protective sheath layer 3 is pasted and connected to the metal sheet 7, and the panel 1 and the electronic board 5 are connected by screws, so the structure is simple and the connection is simple.
