Embodiment
Hybrid relay with reference to the description of drawings embodiment of the present invention.
(execution mode 1)
Fig. 1 is the summary circuit diagram of the internal structure of expression execution mode.
As shown in Figure 1; This hybrid relay 1 is characterised in that; First power supply circuits that utilize mechanical contact switch 12 to form and second power supply circuits that utilize semiconductor switch 13 to form are connected in parallel, and these second power supply circuits possess temperature fuse F1, and to be used as temperature at semiconductor switch 13 be that set point of temperature is closed the safety circuit portion of power supply circuits when above.
This hybrid relay 1 through being connected with terminal 10,11 with AC power 2 and load 3 formation closed-loop paths, this terminal 10,11 is respectively the AC power 2 that is connected in series and an end of load 3.That is, switch on and cut off the power supply through hybrid relay 1 is decided by 2 pairs of loads 3 of AC power for conducting (ON) or by (OFF).At this, for example AC power 2 is made as source power supply of 100V etc., load 3 for example is to comprise the ligthing paraphernalia of fluorescent lamp, incandescent lamp or air exhauster etc.
That is, this hybrid relay 1 possesses: terminal 10, and it is connected with an end of AC power 2, and the other end of this AC power 2 is connected with an end of load 3; Terminal 11, its other end with load 3 is connected; Mechanical contact switch 12 and semiconductor switch 13, their two ends are connected and their parallel with one another connections with terminal 10,11; And signal processing circuit 15.And this mechanical contact switch 12 has the S1 of contact portion.In addition, semiconductor switch 13 has three terminal bidirectional switch S 2, through two ends being connected with mechanical contact switch 12 and terminal 10,11 and being connected in parallel with the S1 of contact portion.And, the conducting (ON) of the closure (ON) of 15 pairs of mechanical contact switch 12 of this signal processing circuit/disconnection (OFF) and semiconductor switch 13/control by (OFF).Mechanical contact switch 12 is made up of S1 of contact portion and solenoid L1, and this solenoid L1 produces and the S1 of contact portion broken off or closed electromagnetic force.The end of solenoid L1 is applied in power supply potential, and the other end is connected with the drain electrode of transistor Tr 1.The base electrode of transistor Tr 1 is transfused to the control signal from signal processing circuit 15, and grounded emitter.Like this, utilize signal processing circuit 15 and be attached thereto the transistor Tr 1 that connects and as drive division mechanical contact switch 12 broken off or closed.
Below, to hybrid relay 1 carry out by 2 pairs of loads of AC power 3 energising and outage respectively the time action explain simply.At first, under situation, apply control signal, make transistor Tr 2 be conducting state (ON) from the base electrode of 15 pairs of transistor Tr 2 of signal processing circuit by 2 pairs of loads of AC power 3 energising.Thus, in semiconductor switch 13, incided photoelectricity three terminal bidirectional switch S 3, make photoelectricity three terminal bidirectional switch S 3 be conducting (ON) from the light signal of light-emitting diode LD.Therefore in addition, photoelectricity three terminal bidirectional switch S 3 possesses the zero passage function, and when detecting alternating voltage from AC power 2 and be center voltage (reference voltage), making photoelectricity three terminal bidirectional switch S 3 is ON.
Make from the alternating current of the AC power 2 photoelectricity three terminal bidirectional switch S 3 of flowing through through this photoelectricity three terminal bidirectional switch S 3 of conducting, therefore the gate electrode to three terminal bidirectional switch S 2 provides electric current, and photoelectricity three terminal bidirectional switch S 3 is ON.Thus, load 3 is electrically connected with AC power 2 via the semiconductor switch 13 in the hybrid relay 1, therefore can utilize 2 pairs of loads of AC power, 3 energisings.Like this; Three terminal bidirectional switch S 2 in making semiconductor switch 13 is connected after the power supply from AC power 2 load 3 for ON; The base electrode of 15 pairs of transistor Tr 1 of signal processing circuit applies control signal, makes transistor Tr 1 be ON, and L1 provides drive current to solenoid.Thus, solenoid L1 produces electromagnetic force, and the S1 of contact portion becomes closure (ON) state.
And; When the S1 of contact portion that utilizes AC power 2 via this mechanical contact switch 12 begins load 3 power supplies; In order to cut off the power supply circuits in the semiconductor switch 13, signal processing circuit 15 makes transistor Tr 2 be cut-off state (OFF), stops to light-emitting diode LD electric current being provided.Therefore, light-emitting diode LD stops luminous action, stops photoelectricity three terminal bidirectional switch S 3 incident optical signals, and therefore when the alternating voltage from AC power 2 was center voltage (reference voltage), photoelectricity three terminal bidirectional switch S 3 stopped action and becomes OFF.And when photoelectricity three terminal bidirectional switch S 3 was OFF, no longer the gate electrode to three terminal bidirectional switch S 2 provided electric current, therefore made three terminal bidirectional switch S 2 be cut-off state, made semiconductor switch 13 be OFF.
On the other hand; Under the situation of cut-out by the power supply of 2 pairs of loads 3 of AC power; The base electrode of 15 pairs of transistor Tr 2 of signal processing circuit applies control signal, makes transistor Tr 2 be ON, to the light signal of photoelectricity three terminal bidirectional switch S 3 incidents from light-emitting diode LD.Thus; Through making photoelectricity three terminal bidirectional switch S 3 be ON for ON makes three terminal bidirectional switch S 2; Except the power supply circuits (first power supply circuits) that utilize mechanical contact switch 12 formation, also in hybrid relay 1, form the power supply circuits (second power supply circuits) that utilize semiconductor switch 13 to constitute.And signal processing circuit 15 makes transistor Tr 1 be OFF, stops to solenoid L1 drive current being provided, and makes the S1 of contact portion for breaking off (OFF) state.Thus, the power supply circuits (first power supply circuits) that can cut off main power supply circuits, promptly utilize mechanical contact switch 12 to form.Afterwards, signal processing circuit 15 makes transistor Tr 2 be OFF, stops to light-emitting diode LD electric current being provided, and makes photoelectricity three terminal bidirectional switch S 3 be OFF thus.Thus,, therefore can cut off the power supply circuits that utilize semiconductor switch 13 to form, therefore can cut off power supply by 2 pairs of loads 3 of AC power owing to make three terminal bidirectional switch S 2 be OFF.
Temperature fuse F1 be fixed on three terminal bidirectional switch S 2 the surface or near, to bring into play function as the detector unit of the abnormal temperature that detects three terminal bidirectional switch S 2.When the temperature of three terminal bidirectional switch S 2 is the abnormal temperature more than the operating temperature; For example when inflow three terminal bidirectional switch S 2 or three terminal bidirectional switch S 2 such as shove owing to reaching the life-span when being short-circuited; This temperature fuse F1 breaks off, and can cut off provides electric current to three terminal bidirectional switch S 2 and photoelectricity three terminal bidirectional switch S 3.Describe about literary composition after the configuration of this temperature fuse F1, but not apply the mechanicalness load and to be configured near the mode of semiconductor switch 13.At this, temperature fuse F1 is configured to make a lead terminal of temperature fuse to be closely attached on the center of the packaging body of semiconductor switch 13 on the protuberance of the packaging body of semiconductor switch 13.
Thus, can protect three terminal bidirectional switch S 2 and photoelectricity three terminal bidirectional switch S 3 to avoid heat damage, can prevent fire etc.At this; The power supply circuits that utilize temperature fuse F1 to cut off are merely the power supply circuits (second power supply circuits) that utilize semiconductor switch 13 to form; Owing to can make and utilize main contacts, be that the power supply circuits (first power supply circuits) that mechanical contact switch 12 forms switch on and off; Even therefore after temperature fuse breaks off, also can carry out load 3 power supplies and outage through the disconnection or the closure of control mechanical contact switch 12.
In addition; In the above-described embodiment; Structure between the connected node of three terminal bidirectional switch S 2 and photoelectricity three terminal bidirectional switch S 3 and terminal 10, being connected with temperature fuse F1 is illustrated; But as variation, also can be made as the structure as Fig. 2 (a), promptly, the temperature fuse F2 that will detect the abnormal temperature of three terminal bidirectional switch S 2 is connected between the electrode and terminal 10 of three terminal bidirectional switch S 2.In addition, also can be made as shown in Fig. 2 (b) such structure, promptly, between an electrode of electrode of photoelectricity three terminal bidirectional switch S 3 and three terminal bidirectional switch S 2 the temperature fuse F3 of the abnormal temperature of joint detection three terminal bidirectional switch S 2.And; When (a) that constitute Fig. 1, Fig. 2 or Fig. 2 (b) such structure; Can adjust allocation position, make it possible to utilize temperature fuse F1, F2 not only to detect the abnormal temperature of three terminal bidirectional switch S 2, also detect the abnormal temperature of photoelectricity three terminal bidirectional switch S 3.
(execution mode 2)
Then, with reference to description of drawings execution mode 2 of the present invention.Fig. 3 is the summary circuit diagram of internal structure of the hybrid relay of expression execution mode 2.In addition, to the part additional phase identical with the hybrid relay of execution mode 1 shown in Figure 1 with Reference numeral, omit its detailed explanation.
As shown in Figure 3, this hybrid relay is following structure: remove temperature fuse F1 from the structure of execution mode shown in Figure 11, be provided with and be connected in the emitter of transistor Tr 1 and the temperature switch S4 between the collector electrode.Thus, different with the relay switch of execution mode 1 shown in Figure 1 aspect the action of only being carried out at temperature switch S4, and other structure, action are identical with the execution mode of Fig. 1, therefore omit its detailed content.Below, the action based on temperature switch S4 is described.
Temperature switch S4 is as bimetal release etc.; The switch that carries out closure or off action by detected temperature is reacted constitutes; With the hybrid relay of the execution mode 1 of Fig. 1 likewise; For the temperature to the three terminal bidirectional switch S 2 in the semiconductor switch 13 detects, this temperature switch S4 be fixed on three terminal bidirectional switch S 2 the surface or near.
As long as three terminal bidirectional switch S 2 is in set point of temperature, then temperature switch S4 is for breaking off the state of (OFF), and ON through transistor Tr 1 or OFF come the drive current that provides or cut off solenoid L1 is controlled.On the other hand, if the temperature of three terminal bidirectional switch S 2 is the temperature that is higher than set point of temperature, then temperature switch S4 is the state of closed (ON), and solenoid L1 is forced to provide drive current.Thus; Produce electromagnetic force by solenoid L1; Make the contact S1 of mechanical contact switch 12 become ON by the strong hand; Therefore form the power supply circuits that utilize this mechanical contact switch 12 to form and be used as main power supply circuits, consequently, can the magnitude of current that flow through the power supply circuits that utilize semiconductor switch 13 formation be suppressed.Thereby the three terminal bidirectional switch S 2 of the formation of flowing through respectively semiconductor switch 13 and the magnitude of current of photoelectricity three terminal bidirectional switch S 3 descend, and therefore can prevent to produce high heat by semiconductor switch 13.

Temperature sensor T1 is made up of the temperature-sensing element of that kind such as thermistor; With temperature fuse F1 in the hybrid relay of the execution mode of Fig. 1 likewise; For the temperature to the three terminal bidirectional switch S 2 in the semiconductor switch 13 detects, with temperature sensor T1 be fixed on three terminal bidirectional switch S 2 the surface or near.And the measurement of the every regulation of temperature sensor T1 is notified the temperature of the semiconductor switch of measuring 13 to signal processing part 15 constantly.
That is, by temperature sensor T1 the temperature of semiconductor switch 13 is detected, if abnormal temperature then drives notice portion 16, taking place to external notification should be unusual.
At this moment, signal processing part 15 can be following structure: the base electrode to transistor Tr 1 applies control signal, makes transistor Tr 1 be ON, thereby makes mechanical contact switch 12 closures.Through like this, can form the power supply circuits that constitute by mechanical contact switch 12 by the strong hand and be used as main power supply circuits, thereby can the magnitude of current that flow through the power supply circuits that utilize semiconductor switch 13 formation be suppressed.Thus, can make and flow through the three terminal bidirectional switch S 2 that constitutes semiconductor switch 13 respectively and the magnitude of current of photoelectricity three terminal bidirectional switch S 3 descends, thereby can prevent that semiconductor switch 13 from producing high heat.In addition, through by the 16 exercise notices action of notice portion, can be abnormal temperature to external notification semiconductor switch 13, can inform the life-span of user's semiconductor switch 13 as early as possible.
In addition, in this case, also can use the temperature fuse F1 of execution mode 1 simultaneously.In addition, the temperature the when temperature that can utilize temperature sensor T 1 that temperature fuse F1 is taken place to fuse this moment is set at than driving notice portion 16 is high, and it is high hot to come prior notice to produce thus.
