Description
Technical field：
A kind of young press-key structure of PCB pots for high pressure injector is the utility model is related to, belongs to medical high-pressure syringe
Technical field.
Background technology：
The corresponding pot son button of each silica gel push-button on the keypad of most of product is 1 currently on the market,
The service life of pot son's button is about 100,000 times during use, so will result in and is led because more using the number of button
Cause pot son's button premature deterioration, it is necessary to which the pcb board more renewed, can cause the whole service life reduction of product, maintenance cost increase.
Based on this, it is necessary to the above problem is provided a kind of by increasing the corresponding pot son button of single silica gel push-button on keypad
Number, and the method for each pot son button parallel connection is improved into the service life in the service life of whole keypad and complete machine.
Utility model content：
The technical problem to be solved by the present invention is to provide a kind of young press-key structure of PCB pots for high pressure injector,
In technical solution, silica gel push-button is installed on front housing, pot son button is attached on button pcb board according to corresponding position, button pcb board
Paste transparent PET pad pastings in the corresponding position of one side of upper metal dome attaching button, it is ensured that during long-time pressing keys, button
Pot son button on pcb board will not shift or deform because of the pressing of high frequency time, and design is scientific and reasonable for it, simple in structure, makes
With it is facilitated, design is scientific and reasonable, simple in structure, easy to use.
A kind of young press-key structure of PCB pots for high pressure injector, its structure include:Front housing, screw, button pcb board,
PET pad pastings, silica gel push-button, pot son button, pot son's key group, the button pcb board is installed on front housing by screw, preceding
Silica gel push-button is installed, pot son button is attached on button pcb board according to corresponding position, metal dome attaching button on button pcb board on shell
The corresponding position of one side paste transparent PET pad pastings, it is ensured that during long-time pressing keys, the pot on button pcb board
Young button will not shift or deform because of the pressing of high frequency time.
Composition pot son's key group of three pot son's buttons on the pcb board, three pot son buttons are in parallel, and operator exists
Press silica gel push-button when, it is ensured that one button of any of which no matter being pressed into three pot son's buttons, at this time pot son button lead
Logical, the action of pressing keys is effective.
The silica gel is by the corresponding top of pot son's button on button pcb board, and silica gel push-button presses key contacts with pot son
Position processing boss, it is ensured that from front housing lateral surface press silica gel push-button when, silica gel push-button can effectively trigger pot below
Young button.
The beneficial effects of the utility model：In the technical solution of the utility model, silica gel push-button is installed on front housing, pot son presses
Key is attached on button pcb board according to corresponding position, and the corresponding position patch of the one side of metal dome attaching button is transparent on button pcb board
PET pad pastings, it is ensured that during long-time pressing keys, the pot son button on button pcb board will not pressing because of high frequency time
Press and shift or deform, design is scientific and reasonable for it, simple in structure, easy to use.
