Abstract
The utility model discloses a kind of panel-switch metal dome pressing structure, including button, the sliding block being connected with button, the wiring board assembly being arranged on base, and the Conductive Rubber Blanket on installation assist side assembly, the top of Conductive Rubber Blanket is provided with the precompressed shirt rim being engaged with sliding block, and its underpart is provided with the metal dome that can be conducted with the golden finger on wiring board assembly.The utility model sets metal dome between Conductive Rubber Blanket bottom and wiring board assembly, button is by sliding block prepressing in Conductive Rubber Blanket, Conductive Rubber Blanket drives metal dome, so that there is the dual feel of conductive rubber and metal dome during operation, the deficiencies of overcoming Conductive Rubber Blanket electrical property low-response, rebound retardation, the shortcomings of compensate for metal dome noise big, Boardy Feeling again so that switching manipulation comfortable feel, electrical property is relatively reliable, and noise is lower.
Description
Technical field
The utility model belongs to vehicle switch technical field, more particularly to a kind of panel-switch metal dome pressing structure.
Background technology
Compared with prior art, existing product is typically by key press microswitch or pressing Conductive Rubber Blanket, to realize
Switching function and operating handle, although but, electrical property response speed low using the slow soft touch of Conductive Rubber Blanket resilience, noise
Slowly.Therefore, how to improve existing switch existing for above mentioned problem, turn into this area urgent problem to be solved.
Utility model content
In consideration of it, the utility model provides a kind of panel-switch metal dome pressing structure, solve existing for existing switch
The problem of electrical property response speed is slow, and there is the advantages of comfortable operation, soft touch, low noise.
Technical scheme is used by the utility model solves its technical problem：A kind of panel-switch metal dome pressing knot
Structure, including button, the sliding block being connected with button, the wiring board assembly being arranged on base, and install on assist side assembly
Conductive Rubber Blanket.Wherein, the precompressed shirt rim being engaged with sliding block is provided with the top of Conductive Rubber Blanket, its underpart is provided with can be with circuit
The metal dome that golden finger on plate assembly is conducted.During work, button promotes sliding block to move downward, and sliding block acts on conducting resinl
Plate, and the metal dome of Conductive Rubber Blanket bottom is deformed, so as to realize the break-make with wiring board assembly.Using as above technology
Scheme, using metal dome resilience it is fast the characteristics of, itself and Conductive Rubber Blanket are combined together so that toggle feel and electrical property are perfect
With reference to, the shortcomings that overcoming Conductive Rubber Blanket electrical property low-response, while make switching manipulation comfortable, soft touch, while effectively drop
Low noise.
Further, Conductive Rubber Blanket design precompressed shirt rim causes sliding block and Conductive Rubber Blanket to have 0.2mm precompressed amount.
Further, it is square for effectively reduction switching manipulation noise, being shaped as metal dome.In addition, in metal dome also
Provided with the bubble point that can be in contact with wiring board assembly, it is ensured that metal dome fully contacts with wiring board assembly, ensures that electrical property can
Lean on.
The beneficial effects of the utility model：The utility model sets pot young between Conductive Rubber Blanket bottom and wiring board assembly
Piece, for button by sliding block prepressing in Conductive Rubber Blanket, Conductive Rubber Blanket drives metal dome so that has conductive rubber and pot during operation
The dual feel of young piece, the deficiencies of overcoming Conductive Rubber Blanket electrical property low-response, rebound retardation, metal dome noise is compensate for again
Greatly, the shortcomings of Boardy Feeling so that switching manipulation comfortable feel, electrical property is relatively reliable, and noise is lower, and meeting client significantly needs
Ask.
Below with reference to drawings and examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the cooperation schematic diagram of Conductive Rubber Blanket and metal dome in the utility model.
Embodiment
Embodiment,
Also referring to Fig. 1 to 2, a kind of panel-switch, including button 1, light conductor 2, sliding block 3, shell 4, wiring board are total
Into 5, base 6, Conductive Rubber Blanket 7, panel 8 and chromed ornament bar 9.
Wherein, button 1 and the assembly and connection of sliding block 3, wiring board assembly 5 are arranged on base 6, and Conductive Rubber Blanket 7 covers online
On road plate assembly 5.
The top of Conductive Rubber Blanket 7 sets precompressed shirt rim 71 sliding block and Conductive Rubber Blanket is had 0.2mm precompressed amount.In conducting resinl
The bottom of plate 7 is provided with the metal dome 72 that can be conducted with the golden finger on wiring board assembly, is provided with metal dome 72 and circuit
The fully contact of plate assembly 5 ensures the reliable bubble point of electrical property.In addition, when metal dome is designed as square, switch behaviour can be effectively reduced
Make noise (being less than 45dB).
During work, button 1 promotes sliding block 3 to move downward, and sliding block 3 acts on Conductive Rubber Blanket 7, and causes under Conductive Rubber Blanket 7
The metal dome 72 in portion deforms, so as to realize the break-make with wiring board assembly.
Described above is only to preferred embodiment of the present utility model, and not the scope of the utility model is defined,
Therefore on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to structure described in the utility model
Make, the equivalence changes that feature and principle are made or decoration, all should fall into the scope of protection of the utility model.
