Abstract
The utility model relates to the new structure of a kind of button printing nonopaque formula manipulation plate, comprise control panel, printed circuit board, button, touch-switch, control panel and printed circuit board are by screw fixed, button is placed on control panel, keytop is carved with light-transmission character, and touch-switch welding on a printed circuit board, touch-switch is equipped with LED light source, it is characterized in that: button acts directly on touch-switch, the light-transmission character on button is illuminated by the LED light source on touch-switch; During pressing keys, touch-switch does not produce displacement, and button is not easily stuck.The utility model has the advantage of that structure is simple, facilitate assembling and the maintenance of product, improve the reliability that manipulation plate uses.
Description
Technical field
The utility model relates to a kind of button printing nonopaque formula manipulation plate, particularly a kind of new structure of military button printing nonopaque formula manipulation plate.
Background technology
Button printing nonopaque formula manipulation plate is one of core component of weapon commanding apparatus, and its reliability plays vital effect to the operational performance improving armament systems.Existing military button printing nonopaque formula manipulation plate is made up of control panel, light conductor, button, printed circuit board, reed, dividing plate, base plate usually, printed circuit board is welded with LED light source, reed adopts double faced adhesive tape and one side rubber seal to limit correspondence position below button on a printed circuit board, then control panel, light conductor, printed circuit board, dividing plate, base plate is fixed together by screw.Prior art is relative complex structurally, and due to reed employing rubber seal location, the contact area of reed and button guide pillar is little, in high temperature environments after long-time pressing keys repeatedly, reed below button easily produces displacement, causes the stuck and signal not conducting phenomenon of button, there is hidden danger of quality.
Utility model content
The purpose of this utility model is the structure simplifying existing button printing nonopaque formula manipulation plate, solves the problems referred to above existing for reed rubber seal location, provides the new structure of a kind of button printing nonopaque formula manipulation plate.
For achieving the above object, the technical solution of the utility model is: a kind of new structure of button printing nonopaque formula manipulation plate, comprise control panel, printed circuit board, button, touch-switch, it is characterized in that: printed circuit board is arranged on the bottom surface of control panel, control panel is fixedly connected with by screw with printed circuit board, button is placed in the key hole on control panel, light-transmission character is carved with on the pressing surface of button, be welded with touch-switch on a printed circuit board, the top of touch-switch is provided with LED light source, contact with the rubber guide pillar circle on touch-switch bottom button.Be arranged on the end face of upper surface lower than the rubber guide pillar circle on touch-switch of the LED light source on touch-switch top.
The utility model has the advantage of that button acts directly on touch-switch, the light-transmission character on button is illuminated by the LED light source on touch-switch; On a printed circuit board, do not produce displacement during pressing keys, button is not easily stuck in touch-switch welding.And structure is simple, facilitates assembling and the maintenance of product, improve the reliability that manipulation plate uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is appearance schematic diagram of the present utility model.
In figure: 1-control panel, 2-button, 3-printed circuit board, 4-screw, 5-LED light source, 6-touch-switch, 7-electric connector, 8-wire, 9-resistance, 10-light-transmission character.
Embodiment
Below with reference to drawings and Examples, the utility model is described in further detail.
As diagram, control panel 1 passes through together with screw 4 fixed with printed circuit board 3.Button 2 protrudes the surface of control panel 1, and button 2 is carved with light-transmission character 10; Touch-switch 6 is welded on printed circuit board 3, and touch-switch 6 is equipped with LED light source 5.
Described button 2 is clear perspex material, and except with except the contact-making surface and light-transmission character 10 of touch-switch 6, its lap is all light tight.In the present embodiment, button 2 withstands on the step of the key hole of control panel 1 by touch-switch 6, and compensates required assembling decrement by the Light deformation of the rubber guide pillar circle of touch-switch 6 end.Because touch-switch 6 is welded on printed circuit board 3, and rubber guide pillar circle with button 2 for face contacts, stressed comparatively even, when pressing keys 2, can not cause the displacement of touch-switch 6, button is not easily stuck.
Wire 8, electric connector 7 described printed circuit board 3 be equipped with, for connection control device power supply (DPS) and signal.When power supply connects LED light source 5 luminescence, the light-transmission character 10 on button 2 is illuminated.In addition, by selecting the resistance of the resistance 9 be welded on printed circuit board 3, the light intensity of adjustable LED light source 5, thus reach the object of the brightness controlling light-transmission character 10.
Below only have expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
Claims (2)
1. the new structure of a button printing nonopaque formula manipulation plate, comprise control panel, printed circuit board, button, touch-switch, it is characterized in that: printed circuit board is arranged on the bottom surface of control panel, control panel is fixedly connected with by screw with printed circuit board, button is placed in the key hole on control panel, light-transmission character is carved with on the pressing surface of button, be welded with touch-switch on a printed circuit board, the top of touch-switch is provided with LED light source, contacts bottom button with the rubber guide pillar circle on touch-switch.
2. the new structure of a kind of button printing nonopaque formula manipulation plate according to claim 1, is characterized in that: the end face of upper surface lower than the rubber guide pillar circle on touch-switch being arranged on the LED light source on touch-switch top.
