Description
Technical field
The utility model is related to a kind of electronic scale in weighing apparatus field, more particularly to a kind of electronic scale keyboard.
Background technology
Electronic scale is to weigh a kind of important instrument in industry, using extensive.Existing electronic scale scale head (such as Fig. 1) includes this
Body 1 and the key circuit plate 2 for being arranged on body interior, if being provided with what is electrically connected with the circuit at its back side on key circuit plate 2
Dry spring key switch, the hemisphere jut button that each touch switch is pasted with face on 3 is corresponding, and this structure causes key circuit
The back side of plate is fitted without the position of battery, it is necessary to install battery elsewhere, installs inconvenience, and cost is high；In addition, touch by
The welding process technological requirement high sensitivity of key switch is relatively low, easily occur reed because fatigue or contact wear, pollution and influence
The use of button.
Utility model content
Needed for defect present in existing electronic scale scale head and reality, the utility model provides a kind of electronic scale key
Disk.
To achieve these goals, the measure that the utility model is taken：
A kind of electronic scale keyboard, including body, the front of body are provided with face patch, and body interior is provided with to be electrically connected with PLC
The key circuit plate and display screen wiring board connect, the front of face patch is provided with several display screens electrically connected with display screen wiring board
The button electrically connected with several with key circuit plate, body interior, which is screwed, is connected with installation panel, the back of the body of face patch
Face is coated with is connected core correspondingly with the one-to-one conductive layer of button, positive be provided with of key circuit plate with conductive layer
Piece, the smooth key circuit board in the back side, which is put, to be installed in the groove that panel front is set, and the back side for installing panel is provided with electricity
Pond, mainboard mounting seat；
The conductive layer is the conductive silver paste that the face that is printed on is sticked or carbon slurry；
The corner of the battery mounting base is provided with the L-shaped buckle raised up, and the both sides of battery mounting base are provided with fixation
The fix bar of battery.
The beneficial effects of the utility model：Cause key circuit plate by the way of conductive silver paste or carbon slurry and face patch are combined
The back side be horizontal structure, be easy to install panel the back side set battery mounting base, facilitate the installation and fixation of battery, save
Installation cost, while the touching process of face patch button and pcb board reduces face patch breakage for plane contact, improves the sensitive of button
Degree.

Embodiment
To overcome defect present in existing electronic scale scale head, real needs are met, a kind of electronic scale keyboard are designed (as schemed
2~Fig. 4), including body 1, the front of body 1 is provided with face patch 3, and body 1 is internally provided with the key circuit electrically connected with PLC
Plate 2 and display screen wiring board 10, if display screen 4 that the front of face patch 3 is electrically connected with display screen wiring board 10 provided with several and
It is screwed inside the dry button 5 electrically connected with key circuit plate 2, body 1 and is connected with installation panel 7, the back of the body of face patch 3
Face is coated with to be connected correspondingly with the one-to-one conductive layer of button 56, positive be provided with of key circuit plate 2 with conductive layer 6
Chip 8 is connect, the smooth holding of key circuit plate 2 in the back side is being installed in the groove that the front of panel 7 is set, and installs the back side of panel 7
It is provided with battery mounting base 9；The conductive layer 6 is the conductive silver paste or carbon slurry being sprayed in face patch 3；The battery mounting base 9
Corner be provided with the L-shaped buckle 12 that raises up, the both sides of battery mounting base 9 are provided with the fix bar 11 of self-contained battery.
The beneficial effects of the utility model：Cause key circuit plate by the way of conductive silver paste or carbon slurry and face patch are combined
The back side be horizontal structure, be easy to install panel the back side set battery mounting base, facilitate the installation and fixation of battery, save
Installation cost, while the sensitivity of button is high.
The simple change and replacement of those ordinary skill in the art is all within protection domain of the present utility model.
