Description
Technical field
The present invention relates to the button of electronic installation, particularly relate to hermetically sealed shock resistance button.
Background technology
The key water-proof structure of current electronic scales, or can only be hermetically sealed, or can only shock resistance, it does not have not only hermetically sealed but also shock proof button.
The hermetically sealed structure of the button of current electronic scales normally welds vernier switch at pcb board, a soft rubber coating in vernier switch upper cover, then monoblock pcb board is sealed waterproof glue, vernier switch is just sealed together with pcb board, then on the upper casing of electronic scales, stretch out a muscle, a panel is pasted again on upper casing, panel has the silk print of button, the muscle on the shell of face will be pressed by pressing silk print region, muscle touches rubber coating again, rubber coating touches the vernier switch on PCB again, thus realizes the function of button.
The shortcoming of this kind of structure has 3 points: one be the combination of rubber coating and the waterproof glue being contained on pcb board is not fine, time length, have steam between rubber coating and glue and infiltrate, thus affect the performance of pcb board; Two is that the feel of button is poor, due between panel to vernier switch will muscle through above covering, rubber coating, could be delivered to vernier switch inner, causes button power big, insensitive; Three is the panel too thin (0.2mm) on surface, it is easy to damaged, causes water or chip can enter title body easily, affects the work-ing life of scale.
In order to increase the shock resistance of button, now commercially also there is metal key-press, shock resistance is the increase in, but can there is a ring gap between this kind of metal key-press and face shell, water or chip easily enter this gap and cause card key, the cost of metal key-press is too high simultaneously, can cause the on the high side of whole title, and client is unwilling to accept.
Summary of the invention
It is an object of the invention to provide a kind of hermetically sealed shock resistance keyboard.
For realizing the hermetically sealed shock resistance keyboard of described object, it is characterized in comprising a body, shock resistance panel, key-press module, seat body comprises groove, key-press module is just arranged in this groove, key-press module comprises circuit card, adhesive waterproof tape, multiple metal dome switches and film, multiple metal dome switches is pasted onto on film, film applying is in the front of circuit card, so that the plurality of metal dome switches forms the switch of this circuit card corresponding to multiple design position of circuit card, adhesive waterproof tape is pasted onto the back side of circuit card, key-press module is pasted on described groove by means of adhesive waterproof tape, the back side of shock resistance panel is pasted on present body by means of waterproof glue, cover described groove, so that described key-press module and described seat body outer side seal completely cut off, the plurality of button pattern corresponding surface is to the plurality of metal dome switches, described groove has an opening, and the wire of described circuit card is drawn from this opening, and this opening is filled by waterproof glue, to seal described groove.
Described hermetically sealed shock resistance keyboard, wherein said circuit card is pcb board.
Described hermetically sealed shock resistance keyboard, wherein said shock resistance panel is PC plate of material.
Described hermetically sealed shock resistance keyboard, wherein said seat body is the upper casing of electronic scales.
Described hermetically sealed shock resistance keyboard, wherein said key-press module also comprises adhesive waterproof tape, and adhesive waterproof tape is pasted onto the back side of circuit card, and key-press module is pasted on described groove by means of adhesive waterproof tape.
In time pressing with finger the pressing pattern of shock resistance panel, panel can be out of shape, and can press metal dome switches by the distortion of panel, and metal dome switches understands the circuit of turning circuit plate after being driven plain, thus realizes the function of button. Realize the shock resistance of keyboard by shock resistance panel, and realize sealing by many places waterproof glue.

Embodiment
Below in conjunction with specific embodiments and the drawings, the invention will be further described; set forth more details in the following description so that fully understanding the present invention; but the present invention obviously can implement with multiple this alternate manner described that is different from; those skilled in the art can do similar popularization, deduction when not running counter to intension of the present invention according to practical situations, therefore should with content constraints protection scope of the present invention of this specific embodiment.
It is noted that these and follow-up other accompanying drawing all only exemplarily, it is not draw according to the condition of equal proportion, and should not be construed as limiting in this, as to the protection domain of the actual requirement of the present invention.
As shown in Figure 1, hermetically sealed shock resistance keyboard comprises a body 6, shock resistance panel 1, key-press module 8. Seat body 6 is generally the housing of electronic installation, and seat body 6 has display area 60, and display area 60 is for arranging various function button, control button, display screen or signal lamp etc. Display area 60 has rectangular recess 62, and key-press module 8 is just arranged in rectangular recess 62. Key-press module 8 comprises pcb board 4, adhesive waterproof tape 5, multiple metal dome switches 3 and film 2, and multiple metal dome switches 3 is pasted onto on film 2, and is arranged in the respective switch position of pcb board 4, and adhesive waterproof tape 5 is pasted onto the back side of pcb board 4. In the process of assembling key-press module 8, positioning fixture is utilized to be pasted onto on the design position of film 2 by multiple metal dome switches 3, film 2 is pasted onto on button pcb board 4, and adhesive waterproof tape 5 is pasted onto the back side of button pcb board 4, so just constitutes a key-press module 8. Shock resistance panel 1 adopts PC material to make usually, and shock resistance panel 1 is formed multiple button pattern 11, button pattern 11 and metal dome switches 3 one_to_one corresponding. Button pattern 11 is normally made by carrying out ink silk screen printing at the back side of panel 1. By means of adhesive waterproof tape 5 key-press module 8 pasted in the rectangular recess 62 of present body 6. Panel 1 back side is covered with waterproof glue, and the display area 60 of present body 6 directly pasted by shock resistance panel 1. The one side of key-press module 8 is sealed by adhesive waterproof tape 5, and opening 61 place of the groove 62 of the only present body 6 of the another side of key-press module 8 does not seal. First button plate wire 7 is welded on the dew copper 42 of pcb board 4, then it is coated on breach 61 with water-proof silica-gel, wait the whole key-press module of nature Feng Ganhou just hermetically sealed.
In time pressing with finger the button pattern 11 of shock resistance panel, panel 1 can be out of shape, pressing metal dome switches 3 by the distortion of panel 1, metal dome switches 3 understands inspection pad 41 and the ground pad of conducting button pcb board after being driven plain, thus realizes the function of button.
Pcb board 4 can also be other forms of circuit card. Seat body 6 as shown in the figure is particularly suitable for the upper casing of electronic scales.
Adhesive waterproof tape 5 mainly plays fixing key-press module 8 in the effect of groove 62, and key-press module 8 can also be fixed in groove 62 by mechanical systems such as card conjunctions. Adhesive waterproof tape 5 also can play the effect of waterproof in some occasion in addition.
