Description

Electronic light touching switch and socket

The utility model relates to a kind of electronics touch-switch and socket, particularly about a kind of touch-switch that produces the little electric current of low-voltage.

Existing normal domestic luminous lamp switch all is a kind of mechanical switch, this kind switch is directly connected with the 220V power circuit, switch and light fixture are impacted by high-voltage large current when turning on light, life-span is influenced fragile, manipulate also dangerous, CN204304U introduces several lighting electronic switchs, the back delay function though turn off the light, because its switch is direct and the rectification bridge circuit joins, this switch is in and is higher than under 220V voltage and the heavy current impact, thereby does not reach the effect that prolongs switch and lamp life, increase fail safe.

The purpose of this utility model is: be subjected to high voltage, heavy current impact fragile at above-mentioned domestic lighting mechanical switch and electronic switch, manipulate unsafe defective, design a kind of electronics touch-switch that produces the little electric current of low-voltage.

The technical scheme that the utility model adopted is: a kind of electronics touch-switch and socket, it is made up of panel, separate cavities, the little current trigger device of low-voltage, socket and binding post, it is characterized in that: the little current trigger device of low-voltage is made up of step-down current-limiting circuit and circuits for triggering; Separate cavities is made up of the central dividing plate of panel, back cover and isolating switch chamber and socket cavity; Panel is that the luminescent layer at night of display switch position is formed by the surface.

The advantage of technique scheme is to adopt the least possible electronic component to realize that the little current trigger device of low-voltage is to guarantee safety and reliability, adopt separate cavities that high-voltage large current circuit and the little current circuit of low pressure are kept apart, make console switch be in safe low-voltage state, guarantee fail safe, the luminescent layer at night of panel makes things convenient for the operation of turning on light night.The circuit not power consumption fully of this programme does not have the misoperation phenomenon in addition.

Fig. 1 is a kind of electronics touch-switch and socket front schematic view.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is an electrical schematic diagram of the present utility model.

Fig. 4 .5.6 is for producing the little electric current of low-voltage 3 kinds of circuit structures and connected mode in addition.

Among above-mentioned Fig. 1,2,1 is panel, and 2 is button, and 3 is elastic contact blade, and 4 is jack cavities, 5 is Die for Reeds of Connector Jack, and 6 is median septum, and 7 for introducing contact pin, and 8 for being connected into post, and 9 are the wiring hold-down screw, 10 is back cover, and 11 are the control printed board, and 12 for triggering printed board, and 13 is panel and back cover hold-down screw.

Existing 1,2,3 structure and the circuit working processes of describing embodiment in conjunction with the accompanying drawings.

Touch-switch button K ₁, K ₂(2), elastic contact blade (3) is formed with parallel affixed triggering printed board (12) with panel (1).Button (2) and jack cavities (4) place on the same panel, many switches single-socket is arranged on panel, or the many sockets of single switch and single switch single-socket etc., the sort of panel back cover corresponding with it all kept apart socket cavity and switch cavity for median septum (6).Panel luminescent material at previous night remove coat around the button or injection moulding on button so that glimmer night, the expression key position.Trigger printed board (12) switch printing forme and button K are set ₁, K ₂Be movably connected.Control printed board (11) is provided with rectification bridge circuit D ₁～D ₄Controllable silicon SCR, resistance R ₁, R ₂And capacitor C.Control printed board (11) is affixed with back cover (10), place median septum top side and parallel with triggering printed board (12), maintenance separates the control printed board (11) of high pressure and low pressure triggering printed board (12) near median septum (6) vertical interval fully, and is reliable to guarantee handling safety.Power supply is by introducing contact pin (7) power supply, and power line and light fixture wiring are tightened up by the hold-down screw (9) of binding post (8).

The little current trigger device of low-voltage is by resistance R ₁, R ₂, capacitor C, controllable silicon SCR and button K ₁, K ₂Form.For making K ₁By the little electric current button of low-voltage K ₁Be serially connected with resistance R ₁And R ₂Between, when pressing K ₁Resistance R ₁Play the current limliting hypotensive effect, and and R ₂Form a bleeder circuit, obtain forward dc voltage at the C two ends, produce a low-voltage and make the SCR conducting by trigger electrode G, A, B two ends have alternating current to pass through, and electric light is lighted.Button K ₂Be serially connected with resistance R ₁With button K ₁Afterwards, and with capacitor C and resistance R ₂Parallel connection, when turning off the light by K ₂The C both end voltage is descended rapidly, and trigger electrode G dead electricity SCR ends, and AB two ends no current extinguishes by electric light.Because K ₁Link position, make R ₁With R ₂Disconnect with C, so the not power consumption fully of this circuit can misoperation yet.

Fig. 4 is the another kind of little electric current connected mode of low-voltage that produces in the utility model circuit, and SCR triggers extreme resistance R among the figure ₂Can omit, its G point dividing potential drop is by resistance R ₁Produce with the impedance of controllable silicon SCR internal fixation.

The connected mode of Fig. 5 is identical with Fig. 4, just button K ₁, K ₂Using two passes of casting aside instead, is turn-off when K beats to 3 the time, if make the switch delay function that mediated.

The connected mode of Fig. 6 is identical with Fig. 5, removes capacitor C and keeps resistance R ₂, when K beats to 2 the time resistance R ₁, R ₂Produce and stablize dividing potential drop triggering SCR conducting, it is turn-off that K beat to 3 o'clock, and trigger electrode voltage becomes 0 rapidly, and controllable silicon SCR is extinguished by lamp.
