Abstract

The utility model relates to an electric switch with a clock display. The switch box of a switching circuit is arranged inside with a clock device, and the display part of the clock device is arranged on the panel of the switch. A lamp switch and a time display device are combined on one device by the utility model with respective enhanced function to bring convenience to the user.

Description

The electric switch that the band clock shows

The utility model relates to a kind of switch of Control current break-make, particularly a kind of civilian electric switch that is installed on the wall.

Known switch normally is contained in the mechanical device of a Control current break-make in the container that an insulating material makes, and button type, key class are arranged.Of a great variety, and outward appearance especially the panel of switch generally all do more attractive in appearancely.But general switching function is all more single, mainly finishes the work of electric current of make-and-break, adds the folding condition of an indicator light display switch at most.Indoor as if be time display screen with the irrelevant utility unit of switch, as wall clock, small alarm clock and so on, but wall clock often is fixed on a place, alarm clock is broken easily as a bibelot, in some very first time of constantly often wishing turning on light, understand and what is in now constantly, for example get up in the night to urinate evening, how long wish when turning on light to know now.Therefore be the function singleness that overcomes switch, and the inconvenience in the time display apparatus use, a kind of can be desirable in conjunction with the product of the two characteristic.

The electric switch that the purpose of this utility model then is to provide a kind of band clock that designs for the deficiency that overcomes known technology to show.

For achieving the above object, scheme of the present utility model is: have in the switch enclosure of switching circuit a clock apparatus is housed, its display part is located on the panel of switch.

Other scheme comprises, described clock apparatus is an electronic installation, its rectification circuit joins with the both ends of power that enters switch, rectification circuit and a clock-pulse circuit join, the output of clock-pulse circuit and an integrated circuit of clock join, the output of integrated circuit of clock connects a display screen, and integrated circuit of clock also joins with a control circuit.

Adopt such scheme, the switch that can will have the family expenses wall installation of kind now links to each other with a time display screen, thereby has seen time showing when using switch, for life brings great convenience.

Below in conjunction with diagram and embodiment scheme is described in more detail.

Fig. 1 is the structure chart of the electric switch of band clock demonstration;

Fig. 2 is the switch panel figure of the electric switch of band clock demonstration;

Fig. 3 is the circuit diagram of the electric switch of band clock demonstration;

The electric switch that band clock as shown in Figure 1 shows combines traditional switch and alarm clock.In the switch as figure, switch enclosure (1) is equipped with contact witch (2), the circuit board of clock apparatus (3), touch-button (4), and display screen (5), formation the application's concrete structure.

Fig. 2 is the panel-form of switch enclosure (1), and according to its internal structure, the element on the panel is respectively contact witch (2), touches button (4) and display screen (5), also has buzzer sound outlet (6) in addition.

Fig. 3 is the electronic-circuit diagram of clock apparatus.Insert lead-in wire N, L from the both ends of power that enters switch enclosure, obtain the required voltage of subsequent conditioning circuit by a bridge rectifier (7) and voltage stabilizing circuit (8), the clock part mainly is made up of clock pulse generator (9) and integrated circuit of clock LM8560.Clock pulse generator is made up of CD4060 and external crystal oscillator etc., can produce very accurate clock pulse.The input of the output pin of clock pulse generator (9) and integrated circuit of clock LM8560 (10) Pin joins, through the shaping circuit of integrated circuit of clock (10), and frequency dividing circuit output per second one H _zStandard signal (it also has output at the pin), drives in integrated circuit " second " counter, 60 pulses of second every input of counter, pulse of output remove to drive " branchs " counter, continuously can show the time with their pulse output end and display screen (5) is corresponding.It is SL-1042-27T that display screen (5) adopts model, wherein Pin reaches

The state of the light-emitting diode indication quarter-bell switch that pin connect.

Integrated circuit of clock (10) Pin and a control circuit join, because this circuit adopt to touch control, with touch button (4) joins C, D, four touch points of E, F are arranged, and join with four touch buttons respectively.C, D, four touch points of E, F join with corresponding triode (13), (14), (15), (16) respectively, and the human-induced signal is amplified into integrated circuit of clock (10) control corresponding end through above-mentioned triode.Wherein the E point is transferred minute, F point timing, and the D point is a clock switch, the C point is the quarter-bell switch.Adjustment is pinned the D button during time, transfers E, F again.

The unlatching of lamp also has a switching circuit control.Insert controllable silicon (17) at both ends of power, and insert load (18) at the silicon controlled major loop, its trigger electrode and a control circuit join, and control circuit is a trigger in fact, are made up of with resistance capacitance triode (19) and (20).Triode (19) is in conducting state at ordinary times, and its current collection is electronegative potential very, ends so triode (21) is lived in strangulation, makes controllable silicon (17) Triggerless and closes.Lamp soft-touch control touch point is G, is connected with a triode (22) that plays amplification, and when the G point provided a touch signal, H point current potential made the trigger upset by the low negative pulse that produces of hypermutation.So the collector electrode of triode (19) is high potential, triode (21) conducting, the output triggering signal makes controllable silicon (17) conducting.After staff left touch point G, circuits for triggering can not overturn, and when touching one time again, trigger were overturn once more, so lamp is closed.

Adopt such scheme, lamp switch and time display apparatus can be combined on the device, strengthened function separately, bring great convenience to the user.

In sum, the utility model is effective.
