Description of the Invention: [Technical Field of the Invention] The present invention relates to a two-wire switching device. [Prior Art] In recent years, electrically operated wiring devices are becoming more and more popular. In connection with this, a three-terminal bidirectional thyristor (TRIAC) or thyristor used as a non-contact switching element is widely used as a switching element of an electronic switching device. However, in a two-wire type switching device (ie, a two-wire switching device), in order to save wiring, its switching element is connected between the AC power supply in series and each end of the load (ie, the load is connected between the two ends of the switching element). One end is connected to the load via an AC power source). Since the power cable cannot be separately inserted into the switching device in this configuration, fixing the power of the switching device becomes a problem. In order to solve the above problem, a two-wire switching device 100 having the circuit structure shown in Fig. 8 has been proposed (for example, see Japanese Patent Application Laid-Open No. H11-237925 (Fig. 1), 2000-133473 (Fig. 1), and 2001-16804 ( figure 1)). The two-wire switching device 100 is a two-wire type wiring device mainly used in a state of being embedded in an indoor wall, and is connected to a commercial power source and a load, for example, by an indoor electric wire of two commercial power sources extending from a switch box mounted indoors. As shown in Fig. 8, the two-wire switching device 100 includes a main switching unit 2, a rectifying unit 3, a first power supply unit 4, a second power supply unit 5, a stabilizing unit 6, a control unit 7, and a sub-switch unit 8. Next, the two-wire switching device 100 will be described in detail with reference to FIG. For example, 23594-PI-607 is shown in Figure 8 as the 'switching device ι〇〇 and is connected to the terminal □] controlled load LF (for example, hairpin Du (commercial pen source) AC and to be gas fan, etc.) Each end. 1 incandescent lamp or fluorescent lamp, and, as shown in Fig. 8, the main switch composed of the two units 2 connected to the terminals T1 and T2 and the wide-direction fluid is connected between the terminals 1 σσ Τ 2 to make it Said, in the load U ΔΓ gate so that one of the terminals is connected to the load via the AC power supply AC at both ends of the main switch unit 2 via the AC power supply terminal 'negative mLF connection', using the AC power supply AC, 2 Close the circuit. In this closed state, the AC power supply AC supplies the load LF with sufficient operating power; and if the main switching unit 2 is turned off, the Ac electric LF provides sufficient electrical power to operate the load LF. The next two = the connection of the load 2 to the terminal - the end is called "· the other end of the terminal T2 is called the "load side terminal, and the other connection is used as the ° 声 ( (n〇ise) filter boundary The air and capacitor π connection 丄= the inductor L is connected to the main switch unit 2 and the terminal T2. The wave rectifying unit 3 has, for example, a pair of wheel-in terminals (hereinafter referred to as input terminals) and a pair of output terminals (below It is called “D铋山子”, and the rectifying unit 3 is composed of a diode bridge, and is rectified by an AC current rotated by the source AC to rotate the rectified current. Second, in unit 3, an AC input terminal is electrically connected to the power supply side terminal of the main switch unit 2 (ie, the main switch unit 2 is connected to the tweezers T1) to the ac power supply 8^"^ 23594-PI-607 One end); and the other AC input terminal is electrically coupled to the negative side, the load side terminal of the LF-connected main switch unit 2 (ie, the other end of the main switch unit 2 of the core to the Id 2) and the gate Extreme. Further, a gate driving circuit is connected between the other AC input terminal of the rectifying unit 3 and the load side terminal of the main switching unit 2, and the gate driving circuit is provided. The electric valley 0 C2 and the resistor R1 are connected in series, and the capacitor C2 and the private resistor R1 are used to turn on the main switching unit 2 by applying a voltage thereto which is greater than or equal to a prescribed threshold value. Therefore, if the DC output terminal of the rectification 3 is short-circuited, the gate voltage is applied to the gate terminal of the main switching unit 2. The first power supply unit 4 includes a resistor R2, one end of which is connected to the rectifying unit. 3. a high voltage DC output terminal; a transistor φ whose collector is connected to the other end of the resistor R2; a resistor R3' is connected between the drain and the base of the transistor Q1; a Zener diode zm, a cathode thereof Connected to the base of the transistor... with its anode connected to ground; and resistor R4, its terminal connected to the emitter of transistor Q1. With this configuration of the first power supply unit 4, the current is limited by the resistors R2 and R4, and the voltage is held and rounded by the Zener diodes. Thus, a DC power supply having a prescribed voltage can be supplied based on the output of the rectifying unit 3. Further, the current that has passed through the Zener diode ZD1 passes through the ground point and returns to the low voltage DC output terminal of the rectifying unit 3. This current is then supplied from terminal T2 to load LF. However, in order to prevent the load LF^ from being erroneously operated, the impedance of the first power supply unit 4 is set relatively high. 23594-PN607 In addition, 'although in the example shown & _ type, for a day a 叮 ' a power supply unit 4 is a dropper type (droppe yPe), you can also use the switch type two power supply unit 5 and wood generation Between the stable single unit 6, and the electric two-body Q2, which is inserted in the rectifying unit 3 Q3, which is used as an enabling unit (==off element; and a transistor off unit for controlling by ^^ Unit) The material conductor opens Q2. More specifically, the control of the seventh to turn on and off the transistor, more specifically, the second power supply φ is connected to the rectifying unit 3 (four) electric ^ 2 including the transistor Q2, the emitter R5 and the capacitor C3, connected: the terminal is strictly rounded; The resistor resistor R6,1 is connected at one end to the 丨:B between the emitter and the base of the body Q2; its collector is connected to the base of R6; the transistor Q3, the resistor R7, is connected to the Thunder, and The emitter is connected to the ground; the polar body ZD2 is connected between the emitter and the base of the cathode; the Zener II D > I collector crystal Q2 collector; and the diode D depolarization is connected to a node, Zener-pole, the connection band 曰-A,, · The inner body ZD2 is transported at this node to the collector of the Q2, which is used to suppress the reverse current. The electric power is turned on in the first power supply unit 5. If the transistor Q3 is turned on, the electric crystal plate Q2 is turned "on" to output the power of the predetermined voltage to the stabilizing unit 6. Therefore 'if the output voltage of the rectifying unit 3 becomes higher than the threshold level (ie, if the cathode voltage of the Zener diode ZD2 becomes higher than or equal to the breakdown voltage), the current supplied from the rectifying unit 3 passes through the Zener The diode ZD2 is then output to the sub-switch unit 8 (i.e., the drain current of the Zener > pole body ZD2 is taken out to the sub-switch unit 8). With such a junction of the second power supply unit 5, the voltage is supplied by the output of the Zener diode 23594-P1-607 23594-P1-607 to provide ZD 2 hold 幷 adjustment so that a DC power supply based on the specified voltage can be used. The stabilizing unit 6 is used to stabilize the slave belt. DC power supply provided by yuan 5. The output of the scale 2 or the second power supply unit L (ie, by a stable output) is used as a protection system. . A ^ ^ 钇疋 兀 6 has been operating early 7 power supply. The stabilizing unit 6 includes a trimmer adjuster (10) the other end of the resistor R4 and a cathode connected to the diode D of the electric junction. Moreover, the lightning used as a buffer *

Electric 敕 合 electrolytic capacitor C5 is used to stabilize the three-terminal adjustment. . The surface of the RG is set to adjust their capacitance according to the adjustment. Further, the electrolytic capacitor B serving as a buffer is charged by a DC power source supplied from the first power source unit 4 or the second power source unit 5. Therefore, when the dc power supply is not supplied from the second power supply unit 5, the electrolytic capacitor B supplies DC power to the stabilizing unit 6. The control unit 7 is constituted by, for example, a CPU or the like. If the control unit 7 receives a k number indicating that the start from the a C power source ac to the load L^ is received from the outer=operating device or the like, the control soap element outputs a control current to the 琶Ba body Q3 in the second power source unit 5. The base is thus electrically connected to the crystal Q2. In this case, the transistor Q2 is turned on to start the operation of the second power supply unit 5 (i.e., to supply DC power from the second power supply unit 5). ' < The sub-switch unit 8 is composed of helium fluid, wherein the anode of the thyristor is electrically coupled to the high voltage DC output terminal of the rectifying unit 3, and the cathode is electrically coupled to the low electric dust of the unit 3327806 23594-PI-607 A unit 3 The DC #out terminal, and the anode of the Zener diode in the two power supply units 5 therebetween.

Therefore, the AC current of the AC power source AC is supplied by the rectifying unit 3: the output of the stream unit 3 to generate the 幷 output meter. When i: the dc power source output from the power source unit 4 is supplied to the 2 capacitor B. Then, the stabilizing unit 6 generates an operation power source of the control unit 7 by using the =C power source, thereby supplying the control unit 7 with the operation power. 'When the hollow unit 7 receives a request for power supply from the external operation device or the like, the control unit 7 outputs the base of the transistor Q3 in the control power supply early element 5, thereby turning on 1327806 23594-P1- 607 transistor Q3. After the transistor Q3 is turned on, it is lowered to turn on the transistor Q2. DC power supply for regulated voltage. Here, the configurator's mainly inputs the second input to the first power supply unit 4. As described above, in the supply of DC power from the second power supply unit 5, the DC power supply charges the electrolytic capacitor b to the right (in the time in Fig. 9).

Further, if the cathode voltage of the Zener diode zm in the second power supply unit becomes south or equal to the breakdown (four), the output of the rectifying unit 3 is transmitted to the (four) unit 8 via the Zener diode ZD2. The current supplied by the h-pole ZD2 (i.e., the leakage current of the Zener diode ZD2) charges the capacitor in the gate circuit of the sub-switch. Therefore, if the voltage of the capacitor C6 becomes higher than or equal to the threshold level, the sub-switch single it 8 is turned on, thereby short-circuiting the Dc output terminal of the rectifying unit 3 (at the time "t2" of Fig. 9).

Thereafter, the current is output from the other AC input terminal of the rectifying unit 3, thereby charging the capacitor C2 in the gate drive of the main_unit 2. Then, if the voltage of the capacitor C2 becomes higher than or equal to the threshold level, the main switching unit 2 is turned on (at time Ύ of Fig. 9), thereby supplying sufficient current to the load LF to start its operation. After the operation of the load LF is started as described above, the main switch unit 2 23594-P 丨-607 stops the voltage rise from the AC power supply Δ p from the AC power to the second: the second turn and the turn f is off. And the current of the Zener diode ZD2 in which the cathode voltage of the rectifying unit 3 becomes high is supplied from the rectifying unit 3 via the voltage of the Zener diode 7D. The above operation is performed; the body ZD2 turns her coffee unit 8, so that the operation is given to the negative sub-switch unit 8. Thereafter, by repeating the same load two supply Ϊ = connection, stopping from the core source to the crystal Q3, the output control current is supplied to the power supply V, and thus the transistor Q3 is cut off, and the lightning is cut. :::ΐ元1:_体Q2, make it: initial ': yuan-power supply two=two=install r_AC power supply list=power supply' then the secondary switch unit 8 is turned on, so that the rectifier main F1 off--the wheel-out terminal is short-circuited . Then, 2 serving as the main switching unit is turned on by the short-circuit current passing through the rectifying unit 3, and thus is supplied from the AC power source AC to the load. Port, when the main switching unit is switched from off to on, the switching voltage (a) the voltage difference between ft1 and Τ2) undergoes a relatively large (mutated) voltage change as shown in FIG. Therefore, a problem that noise becomes large may occur during the on/off switching of the two-wire switching device 100, and/or a current (i.e., load current) supplied to the load LF is distorted. Moreover, depending on the type of load LF, an inrush current may flow into the load LF when the above voltage changes. 13 23594-PI-607 It is said that the above problem is proposed by reducing the Zener diode ZD2 by using the low-voltage drop Schottky one as the two-pole I# and the ten-voltage (breakdown voltage). According to the above method, the maximum value of the switching voltage can be reduced. however,

(4) In this regard, it is possible to attempt to use the other type of half-switch 7L having a lower voltage drop as the semiconductor switching element. However, since the semiconductor switching element: has a TM junction element, the PN junction 7C is formed of a material having a 冋 withstand voltage, so that the voltage drop can only be suppressed to a private limit of =. Therefore, even when a semiconductor switching element of low drop voltage is used, the abrupt change of the switching voltage is not sufficiently suppressed. In this way, the problem explored above has not been resolved.

When the power is supplied from the AC power source to the load, the rectification (2) is generated by the DC power supply; the financial unit is used for the DC generated by the first-generation electrician-power supply. a power supply; a control unit based on:: output for operation 'for operation from the AC power source to the load two-phase power supply early; the sub-switch single it for short-circuiting at the output terminal of the second element; At least, the time at which the gate terminal of the switch 7* and the terminal of the terminal are short-circuited to the main switch is in this configuration, and at least one auxiliary switch unit is composed of the electric light-end bidirectional thyristor (4) The gate terminal of the shut-off unit is two "two small switching voltages" during the time interval from the turn-by-turn unit switching unit of the rectifying unit. Therefore, it is possible to alleviate the abrupt change in the decision from the A c electric^: =, and thus can be reduced; the second is preferably the two-wire open resistor of claim i for controlling the single-stroke from the auxiliary switch The timing of the current supplied by the current supply control unit. By using this junction + structure when switching to 攸 main open, you can control the resistor to switch the current supplied from the previous switch to the single-second sequence from the main switch. Therefore, the main switch unit can be read by a suitable person, 4. When the operation timing of the electricity is captured, the noise is generated, and the noise is produced. The voice is lowered. 15 23594-Pl-6〇7 This =, preferably, the auxiliary switching unit comprises a three-terminal bidirectional thyristor. Therefore, in the structure, the three-terminal bidirectional thyristor is used as an auxiliary switching unit. The gate can reduce the number of components required. In addition, since the size of the three-terminal bidirectional ^ is small and inexpensive, the production cost can also be reduced. In addition, it is preferable that the auxiliary switching unit includes a plurality of semiconductor switches, and it is possible to use a conventional semiconductor switching element to actually cry. Further, it is preferable to connect smoothing electricity between the output terminals of the rectifying unit.

In the structure, the sub-switch unit is made up of field effect electricity. The crystal is formed, and a voltage is gradually applied to the gate of the field effect transistor to turn on the field effect electric body. Therefore, since the output terminal of the rectifying unit is gradually short-circuited by the sub-switch unit, the switching voltage can be reduced. The mutation causes a further noise reduction. In addition, the sub-switch unit includes a semiconductor switching element disposed between the rectifying unit and the stabilizing unit. And a semiconductor switching unit having a Darlington 23594-PI-607 (Darlington) circuit for turning on and off the semiconductor switching element in response to control of the control unit. In this configuration, the semiconductor switching unit is Darlington Therefore, the power supply required for controlling the semiconductor switching unit can be kept low while suppressing the voltage drop by the second power supply unit. Therefore, the switching voltage can be kept low. To make the above and other objects and features of the present invention The advantages and advantages of the present invention will become more apparent from the following description of the preferred embodiments of the present invention. And other objects and features will become apparent. (First Embodiment) A two-wire switching device 1 according to a first embodiment of the present invention is similar to the two-wire switching device 100 shown in Fig. 8 and is mainly embedded in an indoor wall. The two-wire type wiring device used in the state, and the two indoor wires of the commercial power source extending from the switch box installed indoors, for example To the commercial power supply and load. As shown in FIG. 1, the two-wire switching device 1 includes: a main switch unit 2 composed of a three-terminal bidirectional thyristor, wherein a load LF and an AC power source are connected between both ends of the main switch unit 2, One end of the main switching unit 2 is connected to the load LF via an AC power source AC; and the rectifying unit 3 whose input terminals (AC input terminals) are respectively connected to the gate terminal of the main switching unit 2 and the power source side terminal of the main switching unit 2 ( That is, the power supply side terminal of the main switch unit 2 is electrically 1327806 23594-P].607 is lightly coupled to the AC mine VS 3 3 of the *C). Here, the 'rectifier unit 3 is used for the gate of the rectification unit When the terminal (DC wheel terminal) is short-circuited, the gate voltage is applied to the gate terminal of the main opening unit 2.
