Abstract

Disclosed is a waterproof and dustproof keyboard, the structure is: an input press key panel is made of elastic material; a protruding part which is used as input press key and is integrated with the substrate is arranged on a substrate of the press key panel; the bottom surface of the protruding part is provided with contacts corresponding to a printed circuit board arranged at the lower part of the input press key panel; meanwhile, hard key pieces are attached on the larger key surfaces. The utility model adopts the input press key panel with the protruding input press keys on the key panel instead of a plurality of word keys, a word key positioning cover plate and a rubber elastic return part of a traditional keyboard, so that the utility model is not only in simple structure and easy manufacture, but also the weakness of bad waterproof and dustproof performance caused by the gaps among the word keys and the word key positioning cover plate is completely avoided. Therefore, the utility model has the advantages of waterproof, dustproof, good operation hand feeling and long service life.

Description

The water proof and dust proof keyboard

Technical field

The utility model relates to a kind of keyboard, particularly a kind of water proof and dust proof keyboard.

Background technology

The computer keyboard that uses at present and its keyboard of structure of other console keyboard are to be made and be the keyboard of absolute construction setting each other by hard material mostly, the gap that keyboard location cover plate is arranged between keyboard to be constituted is provided with caoutchouc elasticity return spare between each keyboard bottom and printed circuit board (PCB).This structure keyboard is if will guarantee the keyboard regular event, must reserve certain clearance between its each keyboard and keyboard location cover plate, because thereby dust very easily falls into the serviceable life that keyboard has influenced keyboard greatly by this gap, if accidentally water is infiltrated when using on the acute circuit board of seal in the keyboard, will cause more havoc to keyboard.

The utility model content

The utility model is the shortcoming at the water proof and dust proof poor performance that exists in the above-mentioned background technology, provide a kind of simple in structure, be easy to make, water proof and dust proof keyboard that operating handle is good.

Its concrete solution is: the input keypad that adopts a resilient material to constitute, and, the substrate of this input keypad be provided with as the input button use and with the projection of substrate as one, and protruding bottom surface that should projection is provided with and imports the corresponding contact of printed circuit board (PCB) that the keypad bottom is provided with, and make this contact height be lower than height of projection 0.3mm at least, in case the contact wiring board of the contact under the static state causes misoperation during input operation, simultaneously, input stud bump height is at least 1mm, and the interval width between the input button also is at least 1mm, in order to avoid artificial error code.In addition then, be bonded with hard key sheet on the key face of bigger input button (as: Enter, Shift button), to overcome the deficiency of feel difference.

The utility model adopts a resilient material to make to have on it input keypad of projection input button, substitute a plurality of keyboards, keyboard location cover plate, the caoutchouc elasticity return spare of conventional keyboard, make that it is not only simple in structure, be easy to make, and, thoroughly avoided the deficiency of the water proof and dust proof poor performance that causes because of gap between the cover plate of keyboard and keyboard location, its waterproof and dustproof, good, the long service life of operating handle.

Description of drawings

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is the A-A amplification profile of Fig. 1.

Embodiment

Among Fig. 1, Fig. 2, input keypad 1 is made by the resilient material plastic cement, and being provided with according to computer standard keyboard input key position on the substrate 3 of its input keypad 1 highly is the projection input button 4 of 2mm.Printed circuit board (PCB) 6 and surface-mounted integrated circuit all are arranged in the airtight keyboard that is made of input keypad 1 and base plate 7, and each input button 4 protruding bottom surface is provided with and highly is the contact 5 of 1mm.And each contact is all corresponding with each contact of printed circuit board (PCB) that its underpart is provided with, and is bonded with hard key sheet 2 respectively on the bigger key face such as Enter, Shift, space bar.

During use, when pressing input when connecing the input button of the arbitrary projection on the key plate 1, the input stud bump side of this projection and contact 5 are all with stressed, and by corresponding contact on the 5 triggering printed circuit board (PCB)s of contact, finish a control action, then Tu Qi input button is by the elastic reset of himself, for action next time is prepared.

Claims

1, a kind of water proof and dust proof keyboard, it is characterized in that adopting the input keypad (1) of resilient material formation, and, the substrate of this input keypad (3) be provided with as the input button uses and with the projection of substrate as one, and protruding bottom surface that should projection is provided with and imports the corresponding contact (5) of printed circuit board (PCB) (6) of keypad bottom setting.

2, water proof and dust proof keyboard according to claim 1 it is characterized in that importing the stud bump height and be at least 1mm, and contact height should be lower than height of projection 0.3mm at least.

3, water proof and dust proof keyboard according to claim 1 is characterized in that the interval width of importing between button (4) is at least 1mm.

4, water proof and dust proof keyboard according to claim 1 is characterized in that importing on the key face of button and is bonded with hard key sheet (2).
