Abstract
The utility model relates to a touch switch suitable for high-humid environment, which belongs to touch switches, particularly a touch switch applied to high-humid environment. The utility model comprises a control circuit board, a panel, and touch points. The utility model is characterized in that the panel of the touch switch is provided with equipotential conductors which are electrically connected with the control circuit board; the equipotential conductors are mutually insulated with protective earth wires. The equipotential conductors can be provided with an annular shape; the touch points are fixed in the inner circle of the annular equipotential conductors on the panel. The equipotential conductors can be in the shape of a strip and can be the shape of characters, or symbols. The utility model which can not occur misoperations has the advantages of simple structure, high safety, and reliable performance.
Description
The utility model belongs to soft-touch control, particularly about a kind of soft-touch control that is applicable under the high humidity environment.
Original soft-touch control under high humidity environment because in the water vapour electric action of water ion misoperation often takes place, promptly the people does not have soft-touch control and owing to the electric action of water ion in the water vapour is opened switch automatically.Therefore people usually to take for the soft-touch control performance unreliable.
The purpose of this utility model is: a kind of soft-touch control that can switch not opened automatically owing to the electric action of water ion in the water vapour in high humidity environment is provided, and it is simple in structure, and is safe in utilization, dependable performance.
The technical solution of the utility model is: design the soft-touch control under a kind of suitable high humidity environment, it comprises that control circuit board, panel, touch point form, and it is characterized in that: described soft-touch control panel has the equipotential electric conductor; The equipotential electric conductor is electrically connected with control circuit board; Equipotential electric conductor and protection ground wire mutually insulated.
Described equipotential electric conductor can be ring-type, in the touch point is fixed on and justifies in the ring-type equipotential electric conductor on the panel.Described equipotential electric conductor can be a strip; Also can be literal or symbol shape.Described touch point can with the equipotential electric conductor on the same plane of same panel; The touch point can also with the equipotential electric conductor on the Different Plane of same panel.Described soft-touch control panel can be the metal decking of surface conductance, it also can be the panel that the surface has electrically conductive ink, electric conductor on this panel surface can be the equipotential electric conductor, it and be fixed between the touch point on the panel and be connected with insulator so that the equipotential electric conductor mutually insulated on touch point and the panel.
Characteristics of the present utility model are as follows:
1, because described soft-touch control panel has the equipotential electric conductor; The equipotential electric conductor is electrically connected equipotential electric conductor and protection ground wire mutually insulated with control circuit board; so that the static in the water vapour release on the circuit of control circuit board to reduce electrostatic potential by the equipotential electric conductor; play discharge and equipotential effect; thereby in the water vapour electrostatic interaction of water ion on the touch point; switch is opened automatically, misoperation is taken place.Described protection ground wire is the ground wire that connects the earth, but the equipotential electric conductor can be connected with the control ground wire.
2, because equipotential electric conductor ceiling voltage is an essential safety voltage, so safe and reliable when using.
3, the equipotential electric conductor can be connected on the panel with bare metal and constitute, and also can directly directly constitute with the surface exposure metal decking, so production technology is simple, production cost is low.
4, because the equipotential electric conductor can be strip or ring-type, also can be literal or symbol shape, can also make the trade mark shape,, also have identification function so have attractive appearance.
5, the touch point can also with the equipotential electric conductor on the Different Plane of same panel, the touch point can be more outstanding than equipotential electric conductor, is difficult for so in use simultaneously by last touch point and equipotential electric conductor.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Accompanying drawing 2 is the panel construction schematic diagram of embodiment 2 soft-touch controls.
Accompanying drawing 3 is the panel construction schematic diagram of embodiment 3 soft-touch controls.
Among the figure: 1, panel; 2, touch point 3, equipotential electric conductor, 4, insulator.
In Fig. 1, equipotential electric conductor 3 is a ring-type; Touch point 2 is fixed in the interior circle of ring-type equipotential electric conductor of panel 1.At this moment, because equipotential electric conductor 3 is around touch point 2, the equipotential best results.In Fig. 2, equipotential electric conductor 3 directly constitutes with the exposed electric conductor of panel 1 upper surface, equipotential electric conductor 3 on this panel 1 and be fixed between the touch point 2 on the panel 1 and be connected with insulator 4 is so that equipotential electric conductor 3 mutually insulateds of touch point 2 and panel 1.Touch point 2 protrudes in equipotential electric conductor 3, and operation this moment is difficult for taking place misoperation.In the accompanying drawing 3, equipotential electric conductor 3 is made the literal shape, makes to have attractive appearance, but also can play the sign effect.
