Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
In conjunction with shown in Fig. 2 to Fig. 5, schematically show that the touch surface of non-security extra low voltage circuit of the invention is hardened
Structure, including separator 1, panel 2, touch spring 3 and bottom plate 4, separator 1, which is adopted, to be made from an insulative material, and panel 2 uses light-permeable
Material is made, such as glass, transparent plastic, and bottom plate 4 is preferably printed circuit board, and capacitance detecting electricity is provided on printed circuit board
Road.Such as Fig. 1, separator 1 is connected to the inner sidewall of panel 2, and certainly, separator 1 can directly be connected to the inner sidewall of panel 2,
The inner sidewall of panel 2 can be fitted in by modes such as gluings.The first end for touching spring 3 is connected to bottom plate 4, and is electrically connected to
Capacitive detection circuit, the second end for touching spring 3 extend towards panel 2 and are connected on separator 1, and separator 1 is arranged in face
Between plate 2 and the second end for touching spring 3.In this embodiment, separator 1 is preferably made of silica gel material, and silica gel is made
Separator 1 when being tightly attached to the inner sidewall of panel 2, the frictional force of the two is larger, and separator 1 and panel 2 can effectively be avoided to generate
Relative displacement.
Preferably, separator 1 in the normal direction of the panel 2 with a thickness of 1~2mm.
It is straight with spring 3 is touched in the case where touching spring 3 is charging member since separator 1 is insulating element
The separator 1 of contact belongs to " part of support charging member ", and panel 2 then only belongs to " exterior part ", this makes panel 2
Without pressing test by 125 DEG C of ball, panel 2 can be manufactured using more kinds of materials, with the selectivity more horn of plenty of material, favorably
In the perception for promoting product appearance；Simultaneously as separator 1 belongs to " part of support charging member ", therefore separator 1 need to lead to
125 DEG C of ball pressure test is crossed, but separator 1 is located at the inner sidewall of panel 2, does not influence the appearance of product, nor affects on touch bullet
The electrode effect of spring 3, therefore separator 1 can be used and be resistant to 125 DEG C of material and be made, in " charging member " (i.e. touch spring
3) when overheating, separator 1 can prevent panel 2 heated and deteriorate, and then prevent manpower from touching band when product breaks down
Electrical components.In addition, the use material that panel 2 is considerably less than with material of separator 1, therefore compared to the prior art, non-peace of the invention
The touch panel structure of full extra low voltage circuit can (heat-resisting material herein refers to energy using less heat-resisting material
Enough it is resistant to 125 DEG C of material), the production cost of product is significantly reduced, the competitiveness of product is improved.
Specifically, first blocking portion 11 of circle, the first 11 sets of blocking portion are circumferentially equipped with such as Fig. 2 to Fig. 4, on separator 1
It is located at the outside for touching spring 3, the inner sidewall of the first blocking portion 11 is connected to the outside for touching spring 3,11 energy of the first blocking portion
It is enough that the second end for touching spring 3 is limited, it prevents from touching spring 3 and separator 1 generates relative displacement；It is similar in order to realize
Technical effect, separator 1 is equipped with the second blocking portion 12, and the second blocking portion 12, which penetrates, touches spring 3, and the second blocking portion 12
Lateral wall be connected to the inside for touching spring 3, the second blocking portion 12, which can equally prevent from touching spring 3 and separator 1, to be generated
Relative displacement.
Also settable indicator light 41 on bottom plate 4, as shown in Figures 3 to 5, when capacitive detection circuit detects that panel 2 is touched
In time, indicator light 41 is lighted using as operational feedback.Indicator light 41 is located at the inside for touching spring 3, correspondingly, on separator 1
Through-hole 13 is offered, through-hole 13 is located at the inside for touching spring 3, and through-hole 13 allows the light of indicator light 41 to pass through and through panel
2 expose to the external world.
In certain optional embodiments, the light of indicator light 41 scatters towards surrounding and leads to separator 1 four in order to prevent
The panel 2 in week is influenced by the light, and the first blocking portion 11 extends towards bottom plate 4 and is connected to bottom plate 4, such as Fig. 5, at this point, the
The cylindrical structure of one blocking portion 11, the columnar structured both ends are connected to separator 1 and bottom plate 4, touch spring 3,
Indicator light 41 is respectively positioned on the inside of columnar first blocking portion 11, and the first blocking portion 11 can prevent the light of indicator light 41
It is scattered towards surrounding, plays the role of shading, it is ensured that the through-hole 13 that the light of the indicator light 41 only passes through separator 1 exposes to panel
2, separator 1 and the first blocking portion 11 can be used plastic material and be made.
In conclusion the touch panel structure of non-security extra low voltage circuit of the invention, touches spring 3 and panel 2
Between be provided with separator 1, separator 1 is connected to the inner sidewall of panel 2, and touches the end abutment of spring 3 in separator 1
On, separator 1, which is adopted, to be made from an insulative material, it is ensured that touches spring 3 and panel 2 insulate, separator 1 will touch spring 3 and panel 2
It is isolated, even if charging member (i.e. touch spring 3) overheat, separator 1 can also prevent panel 2 heated and deteriorate, Jin Erfang
Only manpower touches charging member when product breaks down, while the material of panel 2 can have richer selectivity, have
Conducive to the appearance for promoting product.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
