１図に示されるような定位置に戻る。 In the structure described above, when inserting the movable electrode 13 between the contact pieces 22, 22, by rotating the movable electrode shaft 12 as is well known, the movable electrode 13 is placed between the contact pieces 22, 22. It is inserted as shown in Figures 1 to 3. In this way, the movable electrode 13
When the movable electrode 13 is inserted between the contact pieces 22, 22, the movable electrode 13 is inserted between the contact pieces 22, 22, since the contact pieces 22, 22 are biased toward each other by the pressing springs 24, 25. movable electrode 1
3 and the contact pieces 22, 22 are electrically connected. In this state, between the movable electrode 13 and the center conductor 4, the contact pieces 22, 22, the arm 20,
20, contact fitting 19, guide rod 16, connecting conductor 30, base 14, fastening piece 10, energizing nut 11
Electricity can be applied via the Next, the movable electrode 13
When pulling out from between the contact pieces 22, 22,
First, the movable electrode shaft 12 is rotated in the opposite direction to that at the time of insertion. At this time, the movable electrode 13 is connected to the contact pieces 22, 2
2, and a large frictional force acts between the movable electrode 13 and the contact pieces 22, 22. Therefore, as shown in FIG. 4, the movable part 15 is moved in the same direction as the movable electrode 13 (extracting direction). Along with this movement, the sliding pieces 39, 39 slide on the guide parts 38, 38. At this time, guide section 3
8 and 38 are constructed in a shape that expands as they face upward (in the pulling direction) in FIG. 4, so the sliding pieces 39 and 39 move in directions away from each other. Due to this movement, the contact pieces 22, 22, which are integral with the sliding pieces 39, 39, also move in the direction away from each other.
Therefore, the frictional force between the movable electrode 13 and the contact pieces 22, 22 becomes smaller. At the moment when the force trying to pull out the movable electrode 13 overcomes the decreasing frictional force, the movable electrode 13 is pulled out from between the contact pieces 22, 22, as shown in FIG. Movable electrode 1
3 is pulled out from between the contact pieces 22, 22,
Due to the elastic force of the connecting conductor 30, the movable part 15 returns to the normal position as shown in FIG.
以上のように接触片２２，２２相互の間が開か

が接触片２２，２２相互の間から引き抜かれる時

極１３を引き抜くことができる。 As described above, the point in time when the space between the contact pieces 22, 22 is opened and the frictional force becomes small, and the movable electrode 13
The point in time when the movable electrode 13 is pulled out from between the contact pieces 22, 22 coincides completely, and the movable electrode 13 can be pulled out from the contact pieces 22, 22 with a weak force without causing any chattering or the like.

続の役割を果す効果がある。 As described above, in the present invention, the two opposing contact pieces 22, 22 are urged in the direction of approaching each other, and the movable electrode 13 is placed between them.
Since the structure is such that the movable electrode 13 is inserted in an interrupted manner, if the movable electrode 13 is inserted between the two contact pieces 22, 22, the movable electrode 1
3 has the effect of electrically conducting to the contact pieces 22, 22 and playing the role of circuit connection.

接触片２２，２２との摩擦抵抗を軽減させる構成
にしてある。これにより可動電極１３は接触片２
２，２２と離れ可動電極１３を軽く抜くことを可

源に要求される駆動力を小さくでき、駆動源の機
構構造を簡易なものに出来る効果がある。もし、
同じ駆動源の力であれば可動電極の引抜速度を速
く出来、早切効果を発輝させることができる。 Furthermore, when the movable electrode 13 is pulled out from the contact pieces 22, 22 to open the circuit, the contact pieces 22, 22 are pulled by the movable electrode 13 and move in the moving direction of the movable electrode 13, and In that case, the sliding pieces 39, 39 extending from the contact pieces 22, 22 move along the guide portions 38, 38 of the guide pieces, so that the contact pieces 22, 22 are gradually separated from each other. The structure is such that the frictional resistance between the movable electrode 13 and the contact pieces 22, 22 is reduced. As a result, the movable electrode 13 is connected to the contact piece 2.
2, 22 and allows the movable electrode 13 to be easily pulled out (the force required to pull out the movable electrode 13 can be reduced). This has the effect of reducing the driving force required of the driving source of the movable electrode 13 and simplifying the mechanical structure of the driving source. if,
If the force of the driving source is the same, the speed at which the movable electrode can be pulled out can be increased, and the early cutting effect can be enhanced.

(1) 可動電極１３を二つの接触片２２，２２から
引き抜く前に広げてチヤタリング発生させた

(2) 可動電極１３を二つの接触片２２，２２から
引き抜いたあとに二つの接触片２２，２２を広

にする、
等の弊害を防止するのに役立つ。 Moreover, during the above-mentioned pulling out, the pulling force of the movable electrode 13 is used to pull the two contact pieces 22, 22.
Since the gap between the two contact pieces 22, 22 is widened, the timing of applying a pulling force to the movable electrode 13 and the timing of spreading the two contact pieces 22, 22 can be matched exactly. This can be caused by: (1) spreading the movable electrode 13 before pulling it out from the two contact pieces 22, 22 to cause chattering; This is useful for preventing problems such as spreading the contact pieces 22, 22 and negating the effect of spreading the two contact pieces 22, 22.

いることを特徴とする開閉器の接触装置。1. Two contact pieces are biased toward each other and faced each other, and a movable electrode configured to move in and out between the two contact pieces,
When the movable electrode is inserted between the two contact pieces, the contact surface of the movable electrode is clamped by the two contact pieces to ensure a firm electrical connection between them. In the contact device, the two contact pieces are configured to freely move forward and backward from a fixed position in the direction in which the movable electrode enters and exits, while a guide piece having at least one end fixed is placed close to the contact piece. At the same time, the guide piece is provided with a guide part extending in the forward and backward direction of the contact piece, and further, the two contact pieces can respectively abut against the guide part of the guide piece. The guide part with which the sliding piece abuts is provided with an elongated sliding piece, and two contact pieces that are pulled and moved by the guide part when the movable electrode retreats are separated from each other via the sliding piece. A contact device for a switch, characterized in that it is sloped so as to
