Description
Technical field
The utility model relates to a kind of signal conduction device, refers to a kind of signal conduction device of touch function input media especially.
Background technology
Generally, touch function input media is provided with several touch function keys on operation user's control panel, and the user pushes the function corresponding key according to the title of difference in functionality key and can select the user to want the function of importing.This touch function input media generally is applied on the household electrical appliance or consumer electronic product than higher gears, for example washing machine, clothes washer-dryer, refrigerator, micro-wave oven, kitchen tools etc.
And touch function input media is divided into infrared-type, resistance-type, surface acoustic wave type, ultrasonic type, piezoelectric type and capacitance touch formula function input media according to its type of sensor.Wherein capacitance touch formula function input media is because it has and can respond to slight well and touch fast, and dust, water and dirt are not afraid of in anti-scraping, and characteristics such as suitable rugged surroundings and being applied in the household electronic products gradually.The principle of work of the touch function input media of this type is to utilize the induction of human body, and when touching contact point, the electric capacity of contact point changes thereupon, thereby can detect the position of touch when certain position of human body (for example finger).For example U.S. Patent application US 2005/0179673 A1 discloses a kind of capacitance type sensor, this sensor comprises that the sensing element of a conduction is coupled to a capacitance measurement circuit, described sensing element comprises a deformable elastic telescopic portion, thereby this pars contractilis is installed in by certain pressure and contacts with control panel below the control panel during installation.When user's touch controls panel during corresponding to the upper zone of this pars contractilis, the electric capacity of described sensing element changes thereupon, can discern user's touch by described capacitance measurement circuit.But, this capacitance type sensor needs certain pressure to make the sensing element elastic deformation be installed on the control panel again after to a certain degree when mounted, and owing to need guarantee the stability of the capacitance variations signal that produced when the user uses, guarantee that simultaneously this sensing element fully contacts with control panel, control panel often is confined at the position that contacts with sensing element on same surface level, and certain radian can not be arranged, so this sensor has certain difficulty on being applied to have the control panel of certain radian or sphere the time.In addition, because the needs of installing, control panel can only with the perpendicular direction of the circuit board at capacitance measurement circuit place on install, and can not be to install on the direction that is parallel to described circuit board, in this case, in the very little situation in circuit board vertical direction space, will bring very big trouble to installation.
And for example, a kind of touch function input media (as shown in Figure 1) that conductive sponge pad 6 is placed the below, touch point of LG company employing.During assembling, need certain pressure that touch point set on this conductive sponge pad 6 and the control panel is fully contacted equally, simultaneously the direction of An Zhuaning also be confined to the perpendicular direction of control panel on.Otherwise, if adopt with direction that control panel parallels on assemble because the friction between control panel and the conductive sponge pad will be easy to cause the dislocation or the displacement of conductive sponge pad, thereby cause the whole functional input media can't operate as normal.This conductive sponge pad the problem of the similar disclosed capacitive type inductive element of patented claim US 2005/0179673 A1 and control panel loose contact or jitter equally also can occur when assembling mutually with the control panel with certain radian or sphere in addition.
Summary of the invention
Therefore, need design a kind of signal stabilization that the touch function input media that is installed in the control panel with certain radian or sphere can be produced and conduct signal conduction device accurately to capacitance measurement circuit.
The purpose of this utility model is to address the above problem provides a kind of signal of touch function input media conduction device, comprise several electrodes, described electrode is connected with a controller by a conducting channel, and wherein said electrode and conducting channel are laid in the film.
Described controller is arranged on the circuit board, being provided with a connector in this circuit board electrically connects with described controller mutually by circuit, described conducting channel comprises linkage section, the splicing ear of connection electrode and the span line that connects linkage section and splicing ear, and wherein splicing ear is plugged in the described connector.The film portion at described linkage section and electrode place is pasted on the inside surface of a touch panel, and the outside surface of described touch panel is respectively equipped with touch sensitive region in the correspondence position of described electrode.On described touch panel, be provided with each function key corresponding to described touch sensitive region.When the user uses, according to each function key, touch corresponding touch sensitive region, the electric signal that the human body contact is produced is transmitted in the controller set on the circuit board by conducting channel, controller is judged the functional requirement that user institute desire is imported according to the different touch sensitive region of human body touch, carries out work thereby start pairing program.
Preferably, described touch panel can be glass material, plastic material or other nonmetallic materials.For transparent touch panel, guaranteed the whole bright and clean attractive in appearance of touch panel thereby cover by the non-transparent material coating in its inside surface.
Described touch panel can be the operation control panel of washing machine or clothes washer-dryer, also can be the operation control panel of household electric refrigerator, the operation control panel of kitchen tools or the operation control panel of other electrical equipment.
By above setting, the film that is provided with some electrodes and conducting channel can be pasted on the inside surface of touch panel easily, and because the characteristic of film itself can be random crooked and being out of shape, therefore can with the touch panel fully contact mutually of arbitrary surface, thereby the change in electric of caused electrode can be accurate, stable when having guaranteed effectively that the user contacts each touch sensitive region is transmitted in the controller.
