Description

1288940 IX. Description of the Invention: 1. Technical Field of the Invention The present invention is directed to a switch that indicates the action state of the load. 2. [Prior Art] It has always been the case that such switches with display lamps are available in various types on the market. A display switch (indicator switch) is used to detect the flow of current through the load, and the current is ignited on the switch to easily recognize the switch in the _ system (lighting is in the illumination). Figure 28 (a) shows the LED, and the lighting mode is constructed by the conventional method of the converter. ·Finance in the open _ part · change flow crying 2 〇, the load current flows through the converter 2G - secondary winding 2 〇 2 (refer to Figure 28 (five)) ° °, then the current, in the secondary winding 203 ( Referring to Fig. 28(c)), an electromotive force (current) is generated, and the electromotive force (current) is used to illuminate the LED 41. The converter 2Q has a set of coils or chips. ^ Winding coil, as shown in Fig. 28 (8), is the outer winding of the primary winding 2〇2, one of the inner side - the person U and the 203 is sandwiched by the upper and lower two cores 2〇1 (cl). ^ 2〇1, using a magnetic material such as a ferromagnetic body. Further, for example, a heat-resistant electric wire is used before the secondary winding 2〇3. The above two-layer winding coil, as in the second, is welded to the second (d2)' to insert the official 25 into the other end (10), that is, complete (d4). The double-layer heat is prone to heat generation due to poor heat. ^I Baizheng

The ring coil system includes coils each wound at a different position A of the donut-shaped core and the secondary winding 203. For the core, for example, a non-material two-crystal crystalline soft magnetic material or the like is used. In this way, the output of the secondary winding or the characteristic is excellent, so the brightness of the LED is increased. With equal output current, = double-layer winding coil is smaller. Because the primary winding and the second [wound (2) can improve the hybridity of the winding, reduce the retention of heat, and suppress the internal g. Next, the operation of the switch SW with the conventional display lamp is described in the switch sw as shown in the figure 1288940 (a). (For example, commercial power supply) E and lamp (load) L are connected in series to a pair of terminals A & A. When the switching unit 6 is turned on, the primary winding 2〇2 of the current transformer 2 has a current “lights L” (lighting). At this time, based on the current, a current is generated in the secondary winding 203, and the light-emitting diode (Led) 41 is turned on. From this state, the switching unit 6 is made

〇FF (the fluorescent lamp 43 is turned on, and the primary winding 202 has no current flowing, so the lamp L is extinguished. With this, the secondary winding 2〇3 also has no current flowing, and the LED 41 is extinguished. The action state of the action 'light L can be easily recognized on the switch 。. Also, 'Fig. 29 (b) shows the circuit when the switch of the second display lamp is used. The terminal A of the circuit A, as shown in Fig. 29 (a), the power source E and the lamp L are connected. The switching portions 6 of the switches SW are exchanged on the same side (the upper side or the lower side in Fig. 29 (6)), and the lamp L and the LEDs are respectively 41 is lighted. From this state, any one of the switching portions 6 is switched to a different side (upper to lower side or lower side to upper side), and the lamp L and each of the LEDs 41 are quenched. The second embodiment is used to illuminate the switch 6 of the LED 41 with the switch sw of the display lamp. When the current transformer 20 is under a low load, the induced voltage of the secondary winding side is small, and the charging is not performed. If the problem is bright, if the number of windings of the primary winding 202 is large, the lamp L is high-loaded, and the converter 2 itself is warmed with the switch SW of the indicator light. Another problem with the use of high magnetic: if 2 body core magnetic permeability relative to the magnetic field strength of the magnetic enthalpy, even if the number of windings of the primary winding 202 is small, the second full current can flow through In other words, because the pass density B 'permeability, the number of turns n, the current I), the higher the magnetic permeability read, the higher the density B. When the above-mentioned body mo ® indicates the L-type incandescent lamp, the white hot lamp flows through the current waveform at the 2〇3 side of the secondary winding, and is secondarily wound (induced voltage). However, the load resistance of the 19 lamps is a thousand voltage input, but the transformer of the core with the above high magnetic permeability is used. When the secondary winding 1288940 is connected to the lighting fixture, the primary winding 202 has a high frequency. The ancient = speed magnetic saturation 'secondary winding 203 has a low induced voltage of 2 generated. Therefore, the law has a very large secondary current flowing. In the 31st figure, when the lamp is reversely illuminated, the appliance is reversed, and the electric winding is reversed. At this time, the secondary winding (10) 3: bis; 203 side _ _ _ voltage is low. The load resistance of t ^ is 15 kΩ. Therefore, the lamp L is usually white, and the LED 41 is expensive when the lamp is used. When the backlight is reversed, the LED 41 does not light up, and the Umbrella uses the error to exceed the specified current value (hereinafter referred to as " The lamp of the sensitive current ") (the negative iiHf electric f flows through) because the converter is heated up a lot, there is a deformation such as a shape of the switch itself with the display lamp. However, Patent Document 1 discloses that the end portion of the secondary winding is connected. In the structure of the open-ended current transformer fixed to the terminal board, in this configuration, the secondary group connected to the light-emitting element can be prevented from being broken by the handle, and the secondary winding can be prevented from being broken. ^ Patent Document 1 Japanese Patent Laid-Open Japanese Patent Publication No. 7-37727 (page, and Fig. 1) 3.

In this state, any one of the switching portions 6 is switched to the different side (upper side to lower side, or lower side to upper side), the lamp L is turned off, and the LED 41 is also turned off. With such a configuration, for example, the switches sw are provided at the separation locations, and the operation state can be recognized from the control of the individual lamps L. Further, a variation of the shape of the sorrow 6 or 7, as in the eleventh or the figure, can also replace the current transformer 2 with the diode bridge 70. The structure of the switch SW is changed in the sixth embodiment, for example, in Fig. 12(a), the change in the seventh embodiment is as shown in Fig. 18, and the diode block 7 is formed into a wire-integrated insert as shown in the eleventh or twelfth (6)' Product. (Embodiment 8) In the sixth embodiment, the inverter 2 () and the switching unit 6·4 ι are provided as in the sixth embodiment, and none of the sixth embodiment is the following characteristic portion. As shown in Fig. 19, the reverse resistance resistor 47' is connected in parallel with the LED 41 and the LED protection resistor 46 on the primary winding 203 side of the current transformer 2A, regardless of the size of the lamp (load) L, and is converted. 16 1288940 When the primary winding 202 has a current containing a high frequency component, the LED 41 is turned on. The converter 20 is constructed using a core having a very high magnetic permeability (not shown). The number of windings of the primary winding 202 is small, and the current value of the lamp (load) L is low, and the converter 2 () can be made twice. The induced voltage on the side of the winding 203 is high, and the current amplitude corresponding to the load current is increased. The current (high-voltage component) of the lamp (load) L connected to the switch (the "switch B portion" of Fig. 19) connected to the indicator light (the "switch B portion" in Fig. 19) flows as the secondary current flows through the primary winding 202. On the secondary winding 203 side, the resistance value with the reverse counter resistance of $47 has electricity = flow. Thereby, the magnetic flux of the core generated by the primary current of the primary winding 2〇2 is eliminated, and the total magnetic flux of the core is lowered to prevent magnetic saturation of the core. As described above, the secondary winding side, the induced voltage is south, so that a large current can flow through the LED 41, and L is smoothly lit. When the L-system is reversely known, as in the 20th (a), when the secondary winding 203 is connected to the counter-resistor 47, the resistance value of the reverse counter-resistor 47 and the reverse anti-counterfeit device 47 The relationship between the two voltages 'induced voltages is as follows. In the ^(a), only the counter-counting resistor 47 is connected to the secondary winding 2〇3 side, such as the 19th II^^7 LED 41, the diode 42, the LE:D protection resistor 46 and 1 The induced voltage obtained by the circuit of '2nd' (4) when the power is connected to the balance is applied to the upper electrode LEJ), the diode 42 and the LED protection resistor 46. In Fig. (^), the horizontal axis represents the resistance value of the counter-resistance resistor 47, and the vertical axis represents the induced voltage with respect to the resistance value of the counter-balance device 47. If the resistance value of 47 is small, the induced voltage is high. On the contrary, when the resistance value is large, the resistance value is 15 kΩ, and the induced voltage is not connected to the reverse. The effective voltage is the same as the resistance value of 15 kΩ. When the resistance value is 15 kΩ, the peak voltage exceeds the LED 41 Ξίΐί pressure (9)! TM41 lights up. In contrast, at no load, at super, the threshold voltage required for the LED 41 to illuminate, can not be lit (4) 4 shi resistance H, mesh, n'pt f 19 diagram, when connected (10) 41, the reverse counter resistor 47 Electricity, 1 is brightly lit due to the flow of a large current. Conversely, the resistance value is 17 1288940. The current flowing through the LED 41 is small and the brightness is low. However, since the resistance value is small, the loss increases. Considering the above, the resistance value of the reverse counter resistor 47 must be set. Thus, the reverse counter resistance 47 is connected in parallel with the LED 41 on the secondary winding 203 side, so that the induced voltage can be greater than that of no load. For general converters that do not use a high permeability core, the core does not have magnetic saturation and the induced voltage is maximum at no load. When the lamp (load) L is a normal white heat lamp, the resistance value of the reverse counter resistor is about 30 times to 50 times that of the LED protection resistor 46 connected in series with the LED 41. The light-emitting characteristics of the LED 41 are not deteriorated. Further, Fig. 21(a) is a side view showing the switch of the display lamp, and Fig. 21 is an exploded side view. The casing 1 includes a current transformer block 2, a pair of primary side terminal portions 3, a bright block 4, a center frame 5, and an opening and closing element block 65. Further, in the pair of primary side terminal portions 1, the terminal portion 34a is provided in the primary side terminal portion 3a, and the terminal portion 34b is provided in the primary side terminal portion 3b. The lock springs 31a and 31b and the terminal portions 34a and 34b constitute the quick junction terminal 7. The terminal portions 34a and 34b also have contacts to open and close the load circuit. The cover 1 includes a handle portion (not shown) that performs an ON-OFF operation by an opening and closing operation by a switching operation, and includes an opening and closing element block 65 for opening and closing a load current. In the W block 2, the current transformer 20 (see Fig. 19) flows through the primary current of the primary winding 202, and generates an induced voltage on the secondary winding 203 (see Fig. 19). (Refer to Figure 19) Lights up. Illuminating the block 4, as shown in Fig. 22(a), on one side of the printed circuit board (for b (single-sided)), the LED 41, the diode that illuminates the lamp (load) L in the (10) state 42. The LED protection resistor 46 and the reverse counter resistor 47 are mounted by, for example, soldering, and the other contact 45 is mounted on the other surface by, for example, soldering or the like. In the illuminating block 4, the printed circuit board 40 and the terminal portion 34b (see Fig. 21) are connected by, for example, soldering, and the connection with the terminal portion 3 is highly reliable. Further, although not shown in Fig. 19, a fluorescent lamp 43 that is lit when the lamp (load) is in the FF state can be attached, and accordingly, the fluorescent lamp protection resistor 44 is also mounted. As described above, according to the eighth embodiment, the reverse counter resistance 47 connected in parallel with the LED 41 or the like is connected to the secondary winding 2〇3 side of the current transformer 2A, the total magnetic flux of the core is reduced, and the lamp (load) L is infinite, and any The light L can smoothly illuminate the led 41. 1288940 In the variation of Embodiment 8, the reverse counter resistance 47 can be replaced, and as shown in Fig. 23, the reverse counter capacitor 48 is connected. The illuminating block 4, as in Fig. 22(c), is the same as the illuminated block 4 of the embodiment 8, except that the reverse counter-resistor 47 is replaced with the counter-counting capacitor 48. With such a configuration, the larger the capacitance of the counter-counting capacitor 48, the higher the magnetic saturation of the core can be caused by the current flowing through the counter-counting capacitor 48, and the effect of the eighth embodiment can be obtained, and the voltage on the side of the secondary winding 203 is low. A large current can flow. On the other hand, in the reverse counter-resistance 47, when the voltage on the secondary winding 203 side is low, the resistance value is still present, and the current is limited. Further, in the modification of the eighth embodiment, the reverse counter resistance 47 and the counter-counting capacitor 48 may be connected in parallel as shown in Fig. 24. The illuminating block 4, as in Fig. 22(b), is the same as the illuminated block 4 of the eighth embodiment except that the reverse counterbalance capacitor 48 is mounted. With such a configuration, the magnetic saturation of the core can be prevented from flowing through the current of the reverse counterbalance capacitor 48, and the effect of both the connection of the reverse counter resistor 47 and the connection of the counter-counting capacitor 48 can be obtained. (Ninth Embodiment) In the ninth embodiment, the inverter 20, the switching unit 6, and the led 41 are provided as in the sixth embodiment, and none of the sixth embodiment is the following characteristic portion. As shown in Fig. 25(a) and Fig. 26(a), the switch of the display lamp with a rated current system such as 4 amps is connected in series with the primary winding 202 of the current transformer 2, and a resistor 49 having a low resistance value is connected. The circuit is blocked when a current exceeding the rated current flows. The resistor 49 is, for example, an allowable power value of about 1/4 watt, and a resistance value of 〇. The resistor ϋ 49 also has a resistor connected to the resistor of the above-mentioned material, and a chip resistor. When the resistor 49 has a current of, for example, about 4 amps, the loss of the resistor 51 is about 160 mW, which does not exceed the allowable power value, and there is no blocking). On the other hand, there is a current flow of about 4 amps per second; the loss of the second 49 is about 1 〇 0 watts, and exceeds the allowable power value, so that the resistor 4 can safely block the circuit. The research and the above 19 1288940 are opened to protect the switch with the indicator light. Therefore, only the change of the form 9 can be substituted for the converter 20, as shown in Fig. 25(b), electric I 7G. As shown in Fig. 27(a), the middle frame 5 is mounted on the diode block 7 and the diode bridge S = and the device 49, as shown in Fig. 27 (6). The diode is electrically connected to the switch with the display lamp, and its current is smaller than the switch provided with the converter 20 (for example, G·5 amps). The diode bridge 7G uses the I cover of the diode and the voltage drop of the skin to generate a voltage to illuminate the LED 41 at both ends. With such k, when a current exceeding the rated current flows, the effect as in Embodiment 9 can be obtained. Another variation of Besch's grievance 9 may be to replace the diode bridge 70. As shown in Fig. 26(b), the resistor 49 is modified. With 1^1341 and diode 42 resistors, capacitor 701. The capacitor 701 is provided for boosting the voltage of the diode bridge 70. In the case of a structure as described above, the effect of Embodiment 9 can be obtained even if there is a current exceeding the rated current. V.
