201126558 閉合更早關閉速通接點,而將電磁石線圈通電激磁。此 時,若是主電路的電壓回復到規定範圍的電壓,由於跳脫 機構的電磁石之電樞被吸附而將致動器保持在後退位置, 因此當把手朝〇N位置移動時,可以確定電路斷路器的再 投入。相對於此,當主電路電壓沒有回復到規定電壓時, 由於電磁石的電樞沒有被吸引,因此即使把手移動到ON 位置,電路斷路器也不會被復歸而回到跳脫狀態。 又附速通接點之欠壓跳脫裝置係與專利文獻1所揭示 的內藏形欠壓裝置相比尺寸爲大形,由於在維持該狀態下 要裝入電路斷路器的殼體內爲困難的,因此通常是如專利 文獻2所示,將單元殼體外接在電路斷路器殼體的側面之 後,介由附設在電路斷路器之旋轉把手(rotary handle)的 驅動桿銜接該速通接點開關機構。 一方面,因爲前述之電路斷路器(配線用斷路器、漏 電斷路器)一般都是安裝在配電盤、分電盤、控制盤等的 盤內,因此作爲其附屬裝置有從盤門的前方開關操作電路 斷路器之“外部操作把手裝置”。作爲其一例,根據裝備 在外部操作把手裝置之旋轉把手的操作,將電路斷路器的 搖動把手(r〇cker handle)在ON、OFF、RESET位置驅動的 方式爲眾所皆知的(例如參照專利文獻3 )。 其次,利用第8圖說明前述外部操作把手裝置之習知 例構造。在第8(a)〜(c)圖中,1爲電路斷路器(配線用斷 路器),2是作爲電路斷路器之附屬裝置並安裝在電路斷 路器殻體的外部操作把手裝置。在此,電路斷路器1係形 201126558 成在殼體la搭載裝備固定接觸子lb、可動接觸子lc、由 反轉動作式之觸發連桿機構組成之開關機構部Id、與該 開關機構部Id銜接而配置在殼體la的頂部之搖動把手 le、及過電流跳脫裝置If等之構成。又5a爲顯示把手4 之ON、OFF、TRIP、RESET位置的銘牌。 上述之電路斷路器1的開關動作係如眾所皆知所示, 當從圖示之ON位置推向右側到OFF位置切換搖動把手 1 e時,在該行程的途中使開關機構部1 d反轉動作,承受 開關機構部1 d之開關彈簧的推壓而使可動接觸子1 c開 啓。又,當檢測主電路之過電流而使過電流跳脫裝置1 f 動作時,使開關機構部1 d釋放動作,而將可動接觸子1 c 開啓斷路主電路電流。又根據該跳脫動作,搖動把手1 e 係在ON位置與OFF位置之中間位置移動而顯示跳脫動作 狀態。 一方面,外部操作把手裝置2係形成在與電路斷路器 1殼體la的頂部螺旋締結而固定的基座3搭載旋轉把手 4、把手蓋板5、及滑動基座6等驅動零件之構成,與旋 轉把手4的支軸4a連結之旋轉基座4b係具備曲柄銷 4c。又前述滑動基座6係以可自由滑動的方式在與電路斷 路器1的搖動把手le平行的方向被導引支撐,在其板面 上係於與滑動方向垂直的方向挖開長孔6 a,在該長孔6 a 嵌入前述曲柄銷4c而與旋轉把手4之間銜接。又在滑動 基座6中,在將外部操作把手裝置2安裝在電路斷路器1 的狀態下,具備與從電路斷路器1的殻體la突出之搖動 -8 -

Field of the Invention The present invention relates to an accessory device for a circuit breaker for a wiring breaker or an earth leakage breaker suitable for a low-voltage power distribution device, and more particularly to a circuit-mounted circuit breaker. The circuit breaker is also used as an accessory for its "undervoltage trip device" and "external operating handle device". [Prior Art] As is well known, various types of accessory devices are prepared in the above-described circuit breakers, one of which is an "undervoltage trip device. The undervoltage trip device is configured to protect As a case where the voltage of the circuit of the object (the voltage of the main circuit or the control circuit) is lower than a predetermined voltage (for example, 85 to 35% of the rated voltage), the circuit breaker is tripped to disconnect the main circuit. It is known to insert a built-in undervoltage trip device that is disposed inside a casing of a circuit breaker (for example, refer to Patent Document 1). The built-in undervoltage trip device is formed in the interior. The cassette housing of the circuit breaker housing is mounted with an electromagnet, an armature coupled to the electromagnet, and an actuator that aligns with the travel latch of the circuit breaker, a release spring of the armature, and an armature The configuration of the trip mechanism of the combination of the reset levers. The operation and function of the undervoltage trip device are described in detail in Patent Document 1 'The electromagnet coil is energized by the control circuit that becomes the power source. -5- 201126558 The main circuit of the circuit breaker, which resists and attracts the armature of the electromagnet during the stabilization time, and holds the aforementioned actuator in the retracted position. On the one hand, when the voltage of the main circuit drops below the specified range The attraction of the electromagnet is lowered to release the restraint of the actuator. Thereby, the spring that receives the release spring pushes the actuator to strike the travel latch to cause the circuit breaker to trip. When the handle of the circuit breaker is put into operation from the OFF position to the ON position after the tripping action, in conjunction with the action, the travel latch of the undervoltage trip device and the release spring resist and the actuator is pulled back to the retracted position. In this state, if the main circuit voltage returns to the range of the predetermined voltage, the electromagnet adsorbs the armature and holds the actuator in the retracted position, so that the re-input of the circuit breaker can be determined. Also, the undervoltage trip device of the circuit breaker In the above-mentioned tripping mechanism, the quick-connecting contact switch is connected, and the quick-connecting contact is connected with the power supply circuit of the electromagnetic stone wire, and the "undervoltage tripping device with the speed-connecting contact point" is also It is well known (for example, refer to Patent Document 2). The undervoltage trip device of the speed-connecting contact is safe and surely inputs the circuit breaker, and is formed in the aforementioned tripping mechanism including the electromagnet. The quick-connecting contact switch mechanism is configured to be connected to the aforementioned quick-connecting contact via a driving lever (cam type lever) provided on a handle of the circuit breaker, in a state in which the device is mounted in the circuit breaker Switching mechanism. In addition, 'after the circuit breaker tripping action, the handle is put into operation. 'When the breaker handle that stops at the TRIP position is moved back to the 0FF position and then moves to the ON position, 'when the circuit breaker is Main circuit contact -6 - 201126558 Closes the quick-connect contact earlier and energizes the electromagnet coil. At this time, if the voltage of the main circuit returns to the specified range, the armature of the electromagnet of the tripping mechanism is adsorbed. The actuator is held in the retracted position, so that when the handle is moved toward the 〇N position, the re-input of the circuit breaker can be determined. On the other hand, when the main circuit voltage does not return to the predetermined voltage, since the armature of the electromagnet is not attracted, even if the handle is moved to the ON position, the circuit breaker is not returned to the trip state. The undervoltage trip device with the speed contact is larger in size than the built-in undervoltage device disclosed in Patent Document 1, and it is difficult to fit in the casing of the circuit breaker while maintaining this state. Therefore, as shown in Patent Document 2, after the unit case is externally attached to the side of the circuit breaker case, the speed contact is engaged via a drive lever attached to a rotary handle of the circuit breaker. Switching mechanism. On the one hand, since the circuit breaker (wiring circuit breaker, earth leakage breaker) described above is generally mounted in a disk of a power distribution board, a distribution board, a control panel, etc., as an accessory thereof, there is a switch operation from the front of the door. The "external operating handle device" of the circuit breaker. As an example thereof, a method of driving a rocking handle of a circuit breaker in an ON, OFF, or RESET position is known according to an operation of a rotary handle equipped with an externally operated handle device (for example, referring to a patent) Literature 3). Next, a conventional example construction of the above-described external operating handle device will be described using Fig. 8. In the eighth (a) to (c) drawings, 1 is a circuit breaker (wiring breaker), and 2 is an external operation handle device which is attached to the circuit breaker housing as an accessory of the circuit breaker. Here, the circuit breaker 1 is shaped as 201126558 to mount the switch mechanism portion Id including the fixed contact lb, the movable contact lc, and the trigger mechanism of the reverse operation type in the housing la, and the switch mechanism portion Id. The rocking handle le disposed at the top of the casing 1 and the overcurrent trip device If are engaged. Further, 5a is a nameplate showing the ON, OFF, TRIP, and RESET positions of the handle 4. As described above, the switching operation of the circuit breaker 1 is as follows. When the swinging handle 1 e is switched from the ON position shown to the right to the OFF position, the switching mechanism portion 1 d is reversed on the way of the stroke. In the turning operation, the movable contact 1 c is opened by the pressing of the switching spring of the switch mechanism portion 1 d. Further, when the overcurrent of the main circuit is detected and the overcurrent trip device 1f is operated, the switching mechanism portion 1d is released, and the movable contact 1c is turned on to open the main circuit current. Further, according to the tripping action, the swinging handle 1 e is moved between the ON position and the OFF position to display the tripping operation state. On the other hand, the external operating handle device 2 is formed by a driving member that is screwed to the top of the casing 1a of the circuit breaker 1 and fixed to the base 3, such as a rotating handle 4, a handle cover 5, and a sliding base 6. The rotary base 4b coupled to the support shaft 4a of the rotary handle 4 is provided with a crank pin 4c. Further, the slide base 6 is slidably supported in a direction parallel to the rocking handle le of the circuit breaker 1, and the long hole 6a is dug in a direction perpendicular to the sliding direction on the plate surface thereof. The long hole 6a is fitted into the crank pin 4c to be engaged with the rotary handle 4. Further, in the slide base 6, in a state where the externally operated handle device 2 is attached to the circuit breaker 1, a grip portion that protrudes from the casing la of the circuit breaker 1 is provided - 8 - 201126558 handle 1 e The push rod 6b facing the cymbal from the ON side and the urging portion facing the handle 1 e are pressed against the pressing spring 6c of the push rod 6b from behind. In the above configuration, when the rotary handle 4 is rotated from the ON position to the 0 FF position by manual operation, the slide base 6 is slidably moved in the right direction via the crank pin 4c, and the circuit is broken by the push rod 6b. The rocking handle le of the device 1 is driven toward the OFF position. Here, when the handle le is displaced to the approximate middle position of the moving stroke, the trigger link mechanism provided in the switching mechanism portion Id of the circuit breaker 1 is reversely operated. Thereby, the movable contact 1c is separated from the fixed contact 1b and moved to the open end position, and the circuit breaker 1 is turned OFF. Further, when the circuit breaker 1 detects an overcurrent and performs the detachment operation, the handle 4 of the external operation handle device 2 engaged with the rocking handle 1e is moved to the TRIP position intermediate the ON position and the OFF position to stop. Further, when the circuit breaker 1 is reinserted from this state, first, the rotary knob 4 is rotated to the RESET position. Thereby, the trip mechanism that is engaged with the switch mechanism portion 1d of the circuit breaker 1 is reset, and then when the rotary handle 4 is reversed and rotated to the ON position, the rocking handle 1e of the circuit breaker 1 is moved to the ON position. The input of the circuit breaker 1 is determined by bringing the movable contact 1C into contact with the fixed contact lb.

Japanese Patent Publication No. 2007-134148 (Fig. 7-8) 201126558 [Explanation] The above-mentioned conventional undervoltage trip device prepared by the manufacturer of the accessory device of the circuit breaker, The correspondence between the externally operated handle device and the selection pattern specified by the user causes the following problems. In other words, the various accessory devices prepared by the manufacturer as the selection of the circuit breaker described above are carried out in accordance with the protection system of the power distribution device and the designation of the user. In this case, as for the selection of the undervoltage trip device, there is a conventional built-in "undervoltage trip device" that does not have a quick-connect contact mechanism as described above (see Patent Document 1), and The type of the undervoltage trip device of the contact (refer to Patent Document 2) is different depending on the model of the circuit breaker, the rated voltage, and the like. Further, there is a case where an external operation handle device is used in combination with a circuit breaker, and the type of the attachment device is various depending on the environment in which the circuit breaker is used, the designation of the user, and the like. For this reason, the manufacturer of the circuit breaker must prepare an undervoltage trip device of a variety of models with different models and styles in order to prevent the user from specifying the selection, and the inventory management of the option may be costly. Further, as an accessory device of the circuit breaker, in the case of using the aforementioned "undervoltage trip device with a speed-connecting contact point" (refer to Patent Document 2), it is necessary to first equip the circuit breaker with a quick-connect contact switch. A dedicated rotary handle with a drive rod that is connected to the mechanism. However, in the case of a normal circuit breaker (refer to Fig. 8), since the standard -10 - 201126558 is equipped with a rocking handle, it is necessary to use the "undervoltage trip device with a speed contact point". Circuit breakers for models with dedicated rotary handles. In addition, in order to prevent the corresponding rotary handle of the circuit breaker from being equipped in advance with the corresponding function of the "undervoltage trip device with the speed contact point", the "undervoltage trip device with the speed contact point" is not used. In the case of the case, there will be an excessive pattern, and there will be a problem that the price of the product of the circuit breaker becomes high. The present invention has been developed in view of the above problems, and the object thereof is directed to an "undervoltage trip device" suitable for a circuit breaker, which first divides the selection related to the undervoltage trip device into a plurality of units. In the configuration, by combining the selected patterns specified by the user, the selected units are combined and used for the circuit breaker, and an accessory device for the circuit breaker that can be easily matched even for a wide variety of designated selection patterns is provided. (Means for Solving the Problem) In order to achieve the above object, according to the present invention, an "external operation handle device" and an "undervoltage trip device" are provided as an accessory device of a circuit breaker of an accessory device, and the aforementioned "undervoltage jump" The "off device" is divided into a "tripping unit" with a tripping mechanism and two modules of a "speeding contact unit" having a quick-connecting contact, and then the aforementioned tripping unit is mounted in the circuit breaker housing. The quick-connecting contact unit externally operates the handle device to connect the aforementioned quick-connecting contact with the internal mechanism of the external operating handle device, and closes with the main circuit contact of the circuit interrupter during the ON operation of the external operating handle device. Earlier -11 - 201126558 The above-mentioned quick-connecting contact (the first application of the patent range) is closed. Specifically, the "external operating handle device" and the "fast-connecting contact unit" are constructed by the following modes. (1) The "external operation handle device" includes: a base attached to the circuit breaker case; a rotary handle; and the operation of converting the rotation of the handle into a linear direction to drive the circuit breaker in the ON and OFF directions a sliding base of a rocker type handle; a push rod mounted on the sliding base opposite to the rocker type handle from an ON operation direction; and a spring that pushes the push rod from the back; and formed on the sliding base and The configuration of the margin stroke is set between the push rods, and the movement of the slide base corresponding to the margin stroke is captured during the operation of the circuit breaker, and the speed contact switch of the speed contact unit is operated (patent application range 2) item). (2) The aforementioned "speed-connecting contact unit" is composed of a combination of a limit switch having a quick-connecting contact and a frame supporting the terminal of the limit switch, and the frame is detachably mounted. In the base of the "external operating handle device", the operating end of the limit switch is engaged with the sliding base of the external operating handle device in the mounting position. (Effect of the Invention) As an accessory device of the circuit breaker, the "undervoltage trip device" is configured as described above, and is applied to the circuit breaker by appropriately selecting the least type of selection, and is also suitable for various designated selection patterns. Can be easily matched. In other words, in the case of an accessory device as a circuit breaker, in the case of a conventional undervoltage trip device without the function of the speed-12-201126558, it is installed in the circuit breaker by the "trip unit" The housing can be used in this case. In this case, the external operating handle device can be installed in the circuit breaker as needed. On the one hand, in the case of the undervoltage tripping device, the selection pattern is changed to the auxiliary speed contact point function.

The susceptor 6 is slidably moved in the linear direction, and as shown in Fig. 8, 'the rocking handle 1 e of the circuit breaker 1 is driven in the ON and OFF positions. Further, Fig. 5 shows an external operation handle device mounted on the circuit breaker 1 (not shown, but in the housing system of the circuit breaker, the "jumping unit" 7) of the undervoltage trip device is provided. (2) The state of the "speed-connecting contact unit" 8 equipped with the under-voltage trip device is additionally used. Here, the quick-connecting contact unit 8 is inserted from the inner side of the support leg 8e provided in the frame 8b thereof. The snap-fit hole that allows the base 3 of the handle device 2 to be externally punched (see Fig. 1) can be detachably snap-fitted. In this assembled state, the terminal 8c of the quick-connect contact unit 8 is inside and closed. The excitation circuit connection of the electromagnet coil hidden in the trip unit 7. On the one hand, the sixth figure shows that the "trip unit" 7 is installed in the housing of the circuit breaker 1 without using the quick-connect contact unit 8' In other words, by first dividing the undervoltage trip device into the above-mentioned "jumping unit" 7 and the "fast-connecting contact unit" 8 two selection accessories, the speed-free contact function is applied as an option. In the case of an undervoltage trip device, as shown in Figure 6, by jumping The unit 7 is inserted and disposed in the casing 1 a of the circuit breaker 1 to be used. In the case where the undervoltage trip device has the function of the speed-connecting point, as shown in FIG. 5, by adding the "speed" The contact point unit 8 is mounted on the externally operated handle device 2, and can also simply correspond to the selection mode of the "undervoltage trip device with a speed contact point." Next, the external handle handle device 2 is mounted with the aforementioned speed communication. In the use state of the order -15-201126558, the transition of the quick-contact operation corresponding to the handle operation will be described with reference to Fig. 7. First, the seventh (a) and (e) diagrams show the external operation handle device 2. The rotary knob 4 is stopped in the OFF position. In this state, the slide base 6 is stopped at the left end of the movement stroke by the pressing of the return spring 9 (tension coil spring), and the margin stroke L 1 is at this position. The rear end of the push rod 6b that is pressed by the spring 6c is held between the rear end of the window hole 6e that is opened at the sliding base 6. At this position, the speed contact point disposed on the side of the slide base 6 is held. Limit switch of unit 8 · 8 a and cam groove 6 f of sliding base 6峙, the speed-contact contact is turned OFF. When the rotary handle 4 is rotated from the ON position from this state (refer to Fig. 7(b)), the motion is driven to cause the slide base 6 to start to the right. In this case, the push rod 6b that is pressed from the back by the weak spring 6c is disconnected from the circuit in the stroke range after the start of the movement corresponding to the margin stroke L1 (see the seventh (e) diagram). The rocking handle le of the device abuts, but the rocking handle le remains in the OFF position, and the limit switch 8a is disengaged from the cam groove 6f of the slide base 6 to close the speed-on contact (ON action). The electromagnet coil that forms the "jumping unit" 7 (see Fig. 2(a)) built in the undervoltage trip device is energized and energized. Further, when the rotary handle 4 is further rotated from the position of the seventh figure (b) toward the ON position, the slide base 6 and the push rod 6b integrally press the rocking handle le of the circuit breaker, in the movement stroke In the middle of the process, the trigger mechanism of the switch mechanism portion Id of the circuit breaker (refer to Fig. 8) is rushed to the reverse speed of the operation - 16-201126558. Thereby, the main circuit contact is closed by the pressing of the switch spring that triggers the link mechanism, and the handle 1 e is shaken to the end of the stroke shown in Fig. 7(g) to stop at the ON position. Further, the operation stroke of the swinging handle 1 e accompanying the closing operation of the main circuit contact is indicated by L2 in the figure. When the rocking handle 1 e of the circuit breaker reaches the 〇N position, the rotating handle 4 of the external operating handle device 2 is stopped as shown in Fig. 7(c), after crossing the line slightly beyond the ON position, d) The ON position of the graph. Further, with the operation of the rotary knob 4, the slide base 6 and the push rod 8b are stopped at the position (h) through the seventh drawing (g). Further, the limit switch 8a of the "speed-through contact unit" is kept in an ON state after the main circuit contact of the circuit breaker is closed, and is built in the "jumping unit" 7 (refer to FIG. 2(a) The electromagnet coil is energized and energized. As is apparent from the above description, the undervoltage trip device of the illustrated embodiment can exhibit the "fast speed communication" described in Patent Document 2 by combining the "jumping unit" 7 and the "speed connecting contact unit" 8. The same action and function of the undervoltage trip device of the contact. Further, as described in Patent Document 2, the circuit breaker does not have to be equipped with a dedicated rotary handle that is engaged with the quick-connecting contact, except that the sliding base of the "external operating handle device" is slightly changed, as long as the external operating handle device is added. By externally connecting the aforementioned "speed-connecting contact unit" 8, it is possible to directly use the known built-in undervoltage tripping device (Patent Document 1), and select the style of "undervoltage tripping device with speed connecting function" It is also easy to respond. Thereby, the manufacturer of the circuit breaker has fewer types of selected products to be prepared as an accessory device corresponding to the undervoltage trip device.
