Abstract
The utility model relates to a membrane circuit board with a privacy function. The prior membrane circuit face plate is easy to falsify or steal information. Therefore, the membrane circuit board with the privacy function comprises a base material layer, a plurality of circuit layers are arranged on the base material layer, and insulating adhesive layers are arranged between the adjacent circuit layers. The membrane circuit board with the privacy function is characterized in that an exposed junction point is arranged on at least one circuit layer, and the size, the shape and the quantity of which are mutually corresponding to the corresponding points on an equipped electron device. By adopting the design, when being installed, the exposed junction point and the corresponding points on the equipped electron device are to be aligned and to be mutually contacted, thus the circuits on the circuit layers are communicated, when the membrane circuit board with the privacy function is disclosed by people, the circuits on the circuit layers are cut off, thereby resulting in abnormal work. The membrane circuit board with the privacy function has the advantage of simple structure, convenient processing, anti-theft and strong vandal-proof capability, and is widely applied in, various electrical devices with anti stealthy connection requirements and membrane circuit such as keyboards etc.
Description
Technical field
The utility model relates to a kind of film circuit board with function of keeping secret.
Background technology
Existing thin film circuit panel comprises button, deixis, line layer is arranged or do not have line layer.But can open film face-plate by such or such method, and then detect device interior, physical data is distorted or steals information easily by the people.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and a kind of film circuit board with function of keeping secret is provided.
For solving the problems of the technologies described above, the film circuit board of this band function of keeping secret comprises substrate layer, this substrate layer is provided with the multilayer circuit layer, be provided with the insulation glue-line between the adjacent circuit layer, it is characterized in that: have at least one deck circuit layer to be provided with the junction point of exposing, the corresponding points on the electronic equipment of its size, shape, quantity and adapted are corresponding.The junction point can be arranged on the circuit layer of being close to substrate, also can with substrate some circuit layers at interval, can also be arranged on the outermost circuit layer.So design during installation, makes corresponding points on the electronic equipment of the junction point of exposing and adapted align and be in contact with one another, circuit on this circuit layer just has been switched on, if someone opens the film circuit board of this band function of keeping secret, circuit will be cut off on the circuit layer, can't operate as normal.If the circuit on this circuit layer is inserted monitoring and alarming system, can also in time find lawless person's destruction.
As optimization, have at least the local line of one deck circuit layer to be arranged on the little patch, this little patch is with keeping limited fixing between infrabasal plate layer or the circuit layer.Little patch should not influence the junction point and expose.So design, if the lawless person successively peels off the film circuit board of this band function of keeping secret, little patch and on the circuit that adheres to will be shut down, interlock circuit is just destroyed, can't restore.
As optimization, be printed on the insulation glue-line that is banded on the described little patch, described local line is arranged on this insulation glue-line.So design realizes limited fixing, simple in structure, easy to process by the strip insulation glue-line.
As optimization, outermost circuit board is provided with the strong adhesive-layer of insulation, and this strong adhesive-layer that insulate is junction point damaged (not influencing the junction point exposes), and its outside is provided with diaphragm.So design, lawless person attempt with the film circuit board of this band function of keeping secret when the electronic equipment of its application is peeled off, the part circuit of partial circuit layer of the film circuit board of this band function of keeping secret is sticked on the electronic equipment, whole film circuit board is changed beyond recognitionly destroyed, can't restore, can't learn the trend of each layer circuit, as shown in Figure 5.
The film circuit board of this band function of keeping secret has advantage simple in structure, easy to process, antitheft, that anti-damage ability is strong, extensively be suitable for keyboard etc. various have antitheftly connect requirement, have in the electric equipment of thin film circuit.
