Description
Technical field
The utility model is related to membrane switch technology fields, and in particular to a kind of electromagnetic oven thin film switch.
Background technology
Thin film switch has the advantages that moisture-proof grease proofing, tailored appearance, is widely used in electromagnetic oven.However, due to electromagnetism
For stove function mostly with frequency of use height, the thin film switch of electromagnetic oven is also very high by the tactile frequency pressed, and the film of electromagnetic oven is caused to open
Often there is the problem of failure in pass, and the thin film switch in particular for adjusting electromagnetic oven temperature range is easier failure or spirit occur
The problem of sensitivity declines.In this regard, there is an urgent need for optimization and upgrading electromagnetic oven thin film switch performance, with improve entire electromagnetic oven sensitivity and
Service life.
Invention content
For the prior art there are above-mentioned technical problem, the utility model aim is to provide a kind of resilience good, sensitive
Degree height, electromagnetic oven thin film switch with long service life.
For achieving the above object, following technical scheme is provided：
A kind of electromagnetic oven thin film switch, including pcb board, face mask layer, the one side of the pcb board and the face mask layer are provided
One side it is opposite, between the pcb board and the face mask layer be equipped with middle interlayer, in this interlayer be located on pcb board and with it is described
There are spacing, the one sides of the face mask layer to be equipped with upper shrapnel for face mask layer, and a side of the pcb board is equipped with lower shrapnel, institute
State shrapnel and lower shrapnel be outwardly formed and rided out section, the upper shrapnel ride out section and the lower shrapnel ride out a section phase
The section bending that rides out to, the lower shrapnel has a ripple glaze, the lower shrapnel it is non-confess section pass through with the pcb board it is elastic insulated
Block connects.
Wherein, described elastic insulated piece is rubber.
Wherein, the upper shrapnel rides out that section is U-shaped to ride out section, and the lower shrapnel rides out that section is C-shaped to ride out section.
Wherein, it is stained with contact on the pcb board, the contact is located at the riding out between section and pcb board of the lower shrapnel.
Wherein, the top curved for riding out section of the lower shrapnel has the ripple glaze.
The beneficial effects of the utility model：
Since upper shrapnel and lower shrapnel are touched by riding out section, the pressure for riding out section is big, increases the sensitive of electrical connection
Degree；And the section that rides out of lower shrapnel has ripple glaze, improves the contact probability of shrapnel and lower shrapnel, avoids shrapnel and lower bullet
The problem of piece misplaces and cannot contact, further improves the sensitivity of contact；And there is bullet in the junction of lower shrapnel and pcb board
Property insulating layer, the elastic insulating layer so that lower shrapnel is depressed after can Rapid reset, the irreducible problem of shrapnel is prevented, to carry
The high service life of electromagnetic oven thin film switch.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of electromagnetic oven thin film switch of the utility model.
Reference numeral：
Pcb board --- 1；Face mask layer --- 2；Middle interlayer --- 3；Upper shrapnel --- 4, upper shrapnel ride out section --- 41；
Lower shrapnel --- 5, lower shrapnel --- 51, ripple glaze --- 52 that ride out section；Elastic insulated piece --- 6；Contact --- 7.
Specific implementation mode
The utility model is described in detail below in conjunction with specific embodiment and attached drawing.
Embodiment.
A kind of electromagnetic oven thin film switch of the present embodiment, as shown in Figure 1, including pcb board 1, the one side phase with pcb board 1
To face mask layer 2, middle interlayer 3 is equipped between pcb board 1 and face mask layer 2, middle interlayer 3 is adhered to the plate face of pcb board, and middle interlayer 3
There are spacing with face mask layer 2, and interlayer 3 is used to support pcb board 1 and face mask layer 2 in this.
As shown in Figure 1, the one side of face mask layer 2 has upper shrapnel 4, a side of pcb board 1 to have lower shrapnel 5, upper shrapnel 4
Medium position be outwardly formed it is U-shaped ride out section 41, what the medium position of lower shrapnel 5 was outwardly formed c-type rides out section 51, upper shrapnel
4 ride out section 41 and lower shrapnel 5 ride out 51 phase direction of section, in addition, riding out for lower shrapnel 5 bends to ripple glaze 52 in section 51.
In addition, non-confess of lower shrapnel 5 is connected between section and pcb board 1 by elastic insulated piece 6, to which the lower shrapnel 5 of auxiliary resets.
In the present embodiment, elastic insulated piece 6 is rubber.
In the present embodiment, as shown in Figure 1,1 be stained with contact 7 on pcb board, contact 7 be located at lower shrapnel 5 ride out section 51 with
Between pcb board 1, contact sensitivity of the lower shrapnel 5 with pcb board is improved.
In the present embodiment, lower shrapnel 5 rides out section 51 only in its top curved ripple glaze 52, has both kept lower shrapnel 5 in this way
Elasticity, while simplify preparation process.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
