Abstract
The utility model relates to a film switch assembly which comprises a light-conducting film, a metal spring plate and an exhaust film, wherein a groove matched with the shape of the metal spring plate is arranged on the exhaust film, the exhaust film is located under the light-conducting film, and the metal spring plate is installed in the groove corresponding to the exhaust film. The film switch assembly reduces the thickness of a keyboard, enhances the hand feeling of keys of the metal spring plate, and reduces the production cost.
Description
Technical field
The utility model relates to a kind of membrane switch assemblies, relates in particular to a kind of membrane switch assemblies that is used for the conducting mobile phone key.
Background technology
Mobile phone key is a requisite accessory during mobile phone is manufactured, and membrane switch assemblies is general a kind of cell phone keyboard assembly in the existing mobile phone.Existing cell phone keyboard generally all needs to be designed to and can use under the occasion of not having illumination, so can increase one deck light guiding film on metal dome switches.
As shown in Figure 1, be membrane switch assemblies structural representation of the prior art.Fixedly film 2 and exhaust membrane 4 is bonding by double faced adhesive tape or adhesive sticker, and metal clips 3 is installed in the exhaust membrane 4 corresponding grooves, and the crowning of metal clips 3 is bonded in fixedly on the film 2, and light guiding film 1 is covered on the described fixedly film 2.Need see through in the time of the user key-press dish light guiding film 1 and fixedly film 2 just can press metal clips 3.Because existing membrane switch assemblies is provided with fixedly film of one deck, can make the feel of metal dome switches be subjected to very big influence, also increased the thickness of cell phone keyboard simultaneously to a certain extent, cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of membrane switch assemblies, to reduce keyboard thickness, the button feel of enhancing metal clips.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of membrane switch assemblies, comprise light guiding film, metal clips and exhaust membrane, the face that described exhaust membrane is relative with light guiding film is provided with and the corresponding groove of metal clips shape, and exhaust membrane is positioned under the light guiding film, and metal clips is installed in the corresponding groove of described exhaust membrane.
As seen, adopt the technical solution of the utility model, directly metal clips is arranged on the below of light guiding film, saved fixedly film of the prior art, the light of propagating is evenly distributed on the light-leading film through salient point or the concave point that is provided with on the light-leading film simultaneously, reached and reduced keyboard thickness, strengthened the button feel of metal clips, and reduced the effect of production cost.

Fig. 2: the membrane switch assemblies structural representation in the utility model;
Fig. 3: the utility model metal clips concave face structural representation.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the utility model is described in further detail.
As shown in Figure 2 to Figure 3, be an embodiment of the present utility model.A kind of membrane switch assemblies, comprise light guiding film 1, metal clips 3 and exhaust membrane 4, described exhaust membrane 4 is provided with and the corresponding groove 41 of metal clips 3 shapes, and exhaust membrane 4 is positioned under the light guiding film 1, and metal clips 3 is installed in the described exhaust membrane 4 corresponding grooves 41.
Wherein, the one side that light guiding film 1 and metal clips 3 fit evenly is printed on adhesive sticker, or double faced adhesive tape, with applying light guiding film 1 and metal clips 3 and applying light guiding film 1 and exhaust membrane 4.Salient point or concave point on the light guiding film 1 evenly are provided with.
As shown in Figure 3, the concave face of metal clips 3 has outstanding contact 31, to strengthen the contact-making surface of button and keyboard printed circuit, is beneficial to turning circuit.The above-mentioned concave face arcwall face relative that be metal clips 3 with exhaust membrane 4.Described contact 31 concentrates on the center of metal clips 3 concave faces, can be that 3 points also can be 4 points.The shape of metal clips 3 can be arch, side cut or triangle.
And exhaust membrane 3 is provided with air discharge duct 42, and bubbling and feel are not good when being used to prevent light guiding film 1 and exhaust membrane 3 applyings.
The material of light guiding film 1 and exhaust membrane 4 can be PET, also can be plastics or resin.The material of light guiding film 1 is transparent, and thickness is generally about 0.1mm.
When pushing keyboard, elastic deformation takes place in metal clips 3, and the outstanding contact 31 of metal clips 3 concave faces can fully contact the contact-making surface of keyboard printed circuit, is beneficial to turning circuit.Behind the circuit turn-on, the diode under the keyboard emits beam, and the concave point or the salient point that see through on the light-leading film 1 are propagated, and uniformly light-emitting illuminates keyboard.
As seen, adopt the technical solution of the utility model, directly metal clips is arranged on the below of light guiding film, saved fixedly film of the prior art, the light of propagating is evenly distributed on the light-leading film through salient point or the concave point that is provided with on the light-leading film simultaneously, reduced keyboard thickness, strengthened the button feel of metal clips, and reduced production cost.
In sum, more than be preferred embodiment of the present utility model only, be not to be used to limit protection range of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
