本発明は回路しゃ断器などに用いられる電磁反発接触子
装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electromagnetic repulsion contact device used in a circuit breaker or the like.
この種電磁反発接触子装置は電路の一部に互に電流方向
が異なる平行導体部（最も普及型としては可動接点板と
固定接点板）を形成し、その過電流時の大電流に伴う電
磁反発力を作用させている。This type of electromagnetic repulsion contact device forms parallel conductor parts (the most popular type is a movable contact plate and a fixed contact plate) with different current directions in a part of the electrical circuit, and the electromagnetic repulsion caused by the large current during overcurrent. It exerts a repulsive force.
そこで、その反発力をアップさせるためには平行導体部
を長くすること及びその対面ギャップを極力小さくする
ことが考えられる。Therefore, in order to increase the repulsive force, it is conceivable to lengthen the parallel conductor portions and to minimize the gap between them.
ところで、しゃ断器の寸法制約上その導体部を長くとる
ことは余り得策ではない。However, due to dimensional restrictions on the circuit breaker, it is not a good idea to make the conductor section long.
従って、対面ギャップを縮小することについて検討する
と、過電流しゃ断動作時は耐アーク性からいって開極角
度が大きいほど理想的である。Therefore, when considering reducing the facing gap, it is ideal that the opening angle is larger in terms of arc resistance during overcurrent cutoff operation.
更に、可動接点板を接点の接圧方向（可動接点を固定接
点方向）に弾圧するバネが存圧するが、これは逆に開極
方向と反対側にバネ作用することとなって開極スピード
を半減した。Furthermore, there is a spring that presses the movable contact plate in the contact pressure direction of the contacts (moving the movable contact in the direction of the fixed contact), but this acts as a spring in the opposite direction to the opening direction, increasing the opening speed. It was reduced by half.
本発明は上記の点に鑑みてなしたものであって、即ち、
可動、固定両接点板間の対面ギャップを縮小しても開極
角度は大きく採れ、且っ接圧バネも開極時は逆に可動接
点板の開極を促進することを目的としたものである。The present invention has been made in view of the above points, namely:
Even if the facing gap between the movable and fixed contact plates is reduced, the opening angle can be increased, and the contact pressure spring is also designed to promote the opening of the movable contact plate when opening. be.

Reference numeral 14 denotes a tension spring that is inserted from the free end of the movable contact plate 9, that is, the other arm piece 12b of the presser plate 12.
One end is suspended on a shaft 15 passing through the frame 11, and the other end is suspended on a pin 16 at the base end of the frame 11. Reference numeral 17 denotes a reversing arm, which has a pin 19 at its base end that engages with the downward L-shaped groove 1B of the frame 11, and whose free end is connected to the movable contact plate 9 through the shaft 15 of the holding plate 12. Pivotally supported. Therefore, pin 19 of this frame 11 is connected to pin 5 when the current is not large.
The pin 19 is located in the horizontal part 13a of the letter-shaped groove 18, and when the current is large, the pin 19 is pushed into the F1 part 18b by its tension spring 14 at the same time as the pole is opened. Therefore, when the current is not large, the horizontal portion 13a
A pin 19 is engaged with the movable contact plate 9, and a tension spring 14 causes the movable contact plate 9 to move counterclockwise around the shaft 10, that is, the movable contact plate 9
acts to press against the fixed contact 6 side. Further, when a large current is applied, the pin 19 moves to the vertical portion 18b, and the tension spring 14 acts to press the movable contact plate 9 in the clockwise direction Jcq, which is the opening side. Reference numeral 2D designates a protrusion that moves the pin 19 from the horizontal portion 18a to the traverse portion 18b, and is provided at the base end of the movable contact plate 9. X is a handle drive unit for reversing the frame 11, which includes a first link piece 21 suspending the center of the frame 11 from a shaft 16, and a second link piece 21 connected to the first link piece 21 by a shaft 22. It is made up of a link piece 23, an exception plate 25 which pivots the upper end of the second link piece 26 on a shaft 24, and a tiltable handle 27 that pushes the first link piece 21 at the lower end bin 26. ing. W is the overcurrent operation part, and the bimetal field and latch fitting are 29 degrees! 10, and is engaged with the exception plate 25. Therefore, in the event of an overcurrent, the latch metal fitting 29, 3Ω operates and becomes disconnected from the plate 25.
The exception plate 25 is inverted about the glaze 51, the handle drive part 2 is thrown out of proportion, and the frame 11 is inverted about the axis 13. 32 is an arc extinguishing device facing both contacts 6.8.

A strong electromagnetic repulsive force is generated, which acts to open the movable contact plate 9, and the movable contact plate 9 attempts to reverse with its tension spring 14 via the reversing arm 17, and at this time, the protrusion 2 at the base end
0, the pin 19 is pushed and moved from the horizontal portion 18a to the vertical portion IBb as shown in (c). Therefore, tension spring 1
The line connecting both ends of 40 moves away from the pin 19 toward the opening side, and the spring force acts more and more in the direction of opening the movable contact plate 9, resulting in a larger opening as shown in (2) compared to l/i.

をより更に大きな開極角度となる。In such a case, as shown in Fig. 1, the operation of the overcurrent operating section W causes the handle drive section 2 to become unbalanced, causing the frame 11 to reverse around the shaft 13, and the movable contact plate 9 to open in the state of pi. The opening angle of the pole becomes even larger.
従って、可動接点８の開極は速く、且つ大きな角度をも
