Description
Technical field
The utility model belongs to electronic devices and components field, more particularly to a kind of quiet metal dome.
Background technology
Metal dome, is commonly called as metal clips, is a kind of using ultra-thin（0.05mm-0.2mm thickness）With superhard (general hardness is
Between HV480-550) stainless steel material make bulge-structure.It is mainly used in thin film switch, microswitch, pcb board, printing
In the products such as wiring board, rigid plate.With contact is steady, several big advantage that conduction is strong, resilience is stable, feel is all good.
In PCB fields, generally using one piece of PET thin slice comprising metal clips, on the wiring boards such as PCB or FPC as
Switch uses, plays a part of between user and instrument the device of an important sense of touch type switch to be referred to as metal dome.
The conducting position that metal clips in metal dome is located on pcb board (is predominantly located in the golden finger top on wiring board）, when receiving
When pressing, the central point of metal clips is recessed, touches the circuit on PCB, and so as to form loop, electric current passes through, whole to produce
Product are just able to normal work.Compared with traditional silica gel push-button, metal dome button have more preferable feel, the longer life-span,
The production efficiency using all types of switches of conducting film can indirectly be improved.
However, although existing metal dome can perfectly realize current lead-through function, meeting during its metal clips resilience
Send than larger sound, can so bring certain noise, affect other people work and life.
New can not send sound or the metal dome of the sound of very little can be sent for this reason, it may be necessary to a kind of so that
People do not send sound when using metal dome product, do not interfere with other people.
The content of the invention
The purpose of this utility model is to provide a kind of quiet metal dome, it is intended to solve sound during existing metal dome use
The excessive problem of sound.
The utility model is achieved in that a kind of quiet metal dome, is included in the lower generation depression of pressure effect and causes electricity
Conductance leads to and resilience can occur after pressure is removed and recover the shell fragment of pressurized front shape；Cover on the shell fragment and outside
The first protective layer so as to be delivered to ambient pressure on the shell fragment is deformed upon under power effect；With the first protective layer phase
Even and deform upon so as to ambient pressure to be delivered to the second protective layer of first protective layer under external force；It is arranged on
The 3rd protective layer of the shell fragment is protected and fixed under the shell fragment；The 3rd protective layer is arranged on the described first protection
Between layer and so that the 3rd protective layer and first protective layer are connected with each other so as to internally form the company of individual cavity
Junctor.First protective layer and the second protective layer pull together to form the structure of one layer of hardness is bigger, can preferably absorb shell fragment and return
Power during bullet, reduces shell fragment rebound velocity, so as to play a part of to reduce metal dome resilience sound.
Further technical scheme of the present utility model is：The connector includes connection film layer and the mould release membrance being connected with each other
Layer.
Further technical scheme of the present utility model is：The release film layer includes the first mould release membrance and the second mould release membrance,
First mould release membrance is clipped in the middle the connection film layer with second mould release membrance.
Further technical scheme of the present utility model is：First protective layer is PET one side glues.
Further technical scheme of the present utility model is：Second protective layer is PET one side glues.
Further technical scheme of the present utility model is：The link film layer is PET one side glues.
Further technical scheme of the present utility model is：3rd diaphragm is PET one side glues.
Further technical scheme of the present utility model is：The thickness of first protective layer is 0.01-0.2 mm.Thickness is got over
Thickness, protection film hardness is higher, and the power that can be absorbed is more, but thickness is blocked up can affect feel.
Further technical scheme of the present utility model is：The thickness of second protective layer is 0.01-0.1 mm.
Further technical scheme of the present utility model is：The thickness of the connection film layer is 0.01-0.1 mm.
The beneficial effects of the utility model are：The quiet metal dome that this programme is provided is not being carried out significantly to existing metal dome
Sound is reduced in the case of change, quiet effect is served, this programme is with low cost, operate gradual change, it is applied widely.
Description of the drawings
Fig. 1 is the schematic diagram of the quiet metal dome that the utility model embodiment is provided.
Reference：The diaphragms of 1- first；The diaphragms of 2- second；3- shell fragments；4- links film；5- release film layers；6- the 3rd
Diaphragm.
Specific embodiment
Fig. 1 shows the schematic diagram of the quiet metal dome that the utility model is provided.As schemed, the metal dome provided in this example is
Circular metal dome, but this programme is also applied for other shapes, such as metal dome of the shape such as triangle, square
Quiet metal dome in this specific embodiment be included in pressure effect it is lower there is depression so that current lead-through and removing
Remove after pressure can resilience and recover the shell fragment 3 of pressurized front shape；Cover on the shell fragment 3 and send out under external force
Raw deformation is so as to the first protective layer 1 being delivered to ambient pressure on the shell fragment；It is connected with first protective layer 1 and outside
Deform upon so as to ambient pressure to be delivered to the second protective layer 2 of first protective layer 1 under power effect；It is arranged on the bullet
The 3rd protective layer 6 of the shell fragment 3 is protected and fixed under piece 3；It is arranged on the 3rd protective layer 6 and first protective layer
Between 1 and the 3rd protective layer 6 and first protective layer 1 are connected with each other so as to internally form the company of individual cavity
Junctor.First protective layer and the second protective layer pull together to form the structure of one layer of hardness is bigger, can preferably absorb shell fragment and return
Power during bullet, reduces shell fragment rebound velocity, so as to play a part of to reduce metal dome resilience sound.
The connector includes connection film layer 4 and the release film layer 5 being connected with each other.The release film layer 5 include first from
Type film and the second mould release membrance, first mould release membrance is clipped in the middle the connection film layer 4 with second mould release membrance.
The first protective layer 1, the second protective layer 2, connection film layer 4 are PET one side glues in this example, and its thickness is 0.07
mm.But above-mentioned material species and thickness can be adjusted as needed.
The quiet metal dome that this programme is provided reduces sound in the case where significantly not changed to existing metal dome,
Quiet effect is served, this programme is with low cost, operate gradual change, it is applied widely.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
