なかった。This type of contact switching device generally has a problem in that the contacts are welded due to the arc or bounce arc that occurs when the device is turned on. For this reason, there are contact materials that are based on Ag and have high melting points such as -, SnO, 1nzOz, 5nO2BiOs, etc. dispersed therein to improve arc resistance by raising the melting point. There was a device that used the deflection of a leaf spring to cause the contacts to slide (wipe) together, and at the same time to obtain a cleaning effect. However, the former has the drawbacks of increased contact resistance and temperature rise, and the latter has not yet been a sufficient measure against welding in terms of wiping distance and wiping force.

た。Therefore, an invention has been proposed that achieves both welding resistance and reduction and stabilization of contact resistance by using a high-melting-point arc contact and a low-resistance conductive contact to generate an arc at the arc contact (for example, Patent Application No. 12832/1983,
Utility Model No. 48-21138, Utility Model No. 49-114430
No. etc.). However, these devices have the disadvantage that the conductive contacts that do not generate 7-wires are formed in a larger size than necessary, resulting in high material costs. On the other hand, if the conductive contact is made small, there is a drawback that positioning accuracy of the contact is required and it becomes difficult to adopt a structure in which the contact slides when the contact is operated.

It is an object of the present invention to provide a contact opening/closing device in which the contacts can be slid and the material used for the conductive contacts can be reduced.

ことができる。According to the configuration of the present invention, the driving means brings the pair of arc contacts into contact with each other before the pair of conductive contacts when turning on, and brings the pair of arc contacts into contact with the pair of conductive contacts when breaking. Since it is separated later than the above, contact resistance can be reduced and stabilized, and welding resistance can be improved. In addition, since the pair of conductive contacts are rectangular and are provided so that their longitudinal directions cross each other, the shape of the conductive contacts can be made smaller and the material cost can be reduced. Since there is no need for precision in the relative positional relationship between the contact and the second contact, the position can be easily set, and a configuration in which the arc contacts or the conductive contacts slide together by the driving means can be easily achieved. I can do it.

The arc contacts 9 and 10 are, for example, A, - as an example, and are arranged on the tip side of the first contact 1 and the second contact 2. Said conductive contacts 11.12 are for example 8g
In this embodiment, the arc contacts 9 and 10 of the first contact 1 and the second contact 2 are arranged closer to the proximal end.

位置とを決定するものとする。FIG. 4 shows the relative positional relationship between the first contactor 1 and the second contactor 2. In other words, A has card 15, which will be described later, as the first card.
B indicates the distance from the position where the card 15 engages with the first contact 1 to the conductive contact 11.
The distance from the engaged position to the arc contact 9.10 is shown, d is the thickness of the arc contact 9.10 in the contact state, d

It is Ad/B. That is, when d=0 at the time of turning on and cutting off, there is no gap d' between the conductive contacts 11 and 12 due to contact wear. shall be determined.
これにより、導電接点11.12間では投入時。As a result, when the conductive contacts 11 and 12 are turned on.
しゃ断時ともにアークを発生せず、通電のみであるので
導電接点11.12の形状を小さくすることができる。Since no arc is generated at the time of interruption and only energization occurs, the shape of the conductive contacts 11 and 12 can be made small.

The return spring 13 is a plate spring bent into a wave shape, and has a hole at one end connected to the protrusion 14a of the base 14 by caulking, and a hole at the other end connected to the protrusion 1a at the base end of the first contact 1 by caulking. Then, the return spring 13 moves the first contact l to the second
is biased in the direction away from the contact 2. The card 15 engages its groove 16 with the middle part of the first contact 1 and is operated downward in FIG. 1 to close the first contact 1 to the second contact 2.

る。The operation will be explained. Figure 1 shows the off state;
FIG. 2 shows a state in which the card 15 is operated from the state shown in FIG. 1 to push the first contact 1 downward (indicated by the arrow). At this time, since the first contact 1 is supported by the return spring 13,
The tip of the first contact 1 on the opposite side from the return spring 13 approaches the second contact 2, and the arc contact 9 moves to the arc contact 10.
come into contact with. This is the state immediately after it is turned on. In FIG. 3, the card 15 is pushed further downward, and in FIG. 2, the base end side of the first contact 1 rotates around the contact portion of the arc contact 9, 10 as a fulcrum, and the return spring 13 is bent. As a result, the conductive contacts 11 and 12 come into contact with each other, and further, the base ends of the conductive contacts 11 and 12 rotate around the contact portions as fulcrums, causing the arc contacts 9 and 10 to separate slightly, and the return spring 13 A state in which contact pressure is applied to the conductive contacts 11 and 12,
This is the final on state. On the other hand, the OFF operation releases the pressing force applied to the card 15. That is, as the first contact 1 is moved apart by the return spring 13 from the state shown in FIG. From this state, the arc contacts 9 and 10 are separated from each other as shown in FIG.

アーク接点9゜10は高融点であるため耐溶着性を有す

接触抵抗が決まり、アークの影響を受けないため安定性
がある。Thus, in the closing state, the arc contacts 9, 10 are closed before the conductive contacts 11.12, and in the cut-off state, the arc contacts 9, 10 are separated after the conductive contacts 11.12. Therefore, the arc or bounce arc that occurs when turning on is always between the arc contacts 9 and 10,
Since the arc contact 9°10 has a high melting point, it has welding resistance. Further, the contact resistance is determined by the low resistance conductive contacts 11 and 12, and stability is achieved because the contact resistance is not affected by arcing.
また、導電接点11.12にはアークが発生しないため
、耐アークを考慮して大きい形状にする必要がなく、そ
のためへg材料が削減できる。Further, since no arc occurs in the conductive contacts 11, 12, there is no need to make them large in consideration of arc resistance, and therefore the amount of material can be reduced.

。Further, in the driving means 3, as the first contactor 1 moves, the first contactor 1 moves in a direction perpendicular to the operating direction,
This causes arc contact 9. lO and conductive contacts 11.1
Since sliding (wiping) between the two members occurs, it helps to stabilize welding resistance and contact resistance, and the groove 1 of the card 15
By engaging the first contact 1 with 6, excessive movement of the first contact 1 in a direction perpendicular to the operating direction is prevented.

位置設定が容易になる。Furthermore, if the shape of the conductive contact 11.12 is too small, it will be difficult for the arc contact 9.10 and the conductive contact 11°12 to slide. Therefore, they can slide against each other, and the contact area can always be kept constant. Moreover, the first
Since precision is not required for the relative positional relationship between the contact 1 and the second contact 2, a margin can be taken in the design.
Positioning becomes easier.

成を容易に取ることができるという効果がある。[Effects of the Invention] According to the contact opening/closing device of the present invention, the driving means causes the pair of arc contacts to come into contact with each other before the pair of conductive contacts when turning on, and brings the pair of arc contacts into contact with each other when cutting off. Since the conductive contacts are separated from each other later than the pair of conductive contacts, contact resistance can be reduced and stabilized, and welding resistance can be improved. Also, since the pair of conductive contacts are rectangular and are provided so that their longitudinal directions intersect with each other in a crisscross manner, yL? (ii) The shape of the contact can be made smaller, reducing the material cost, and since there is no need for accuracy in the relative positional relationship between the first contact and the second contact, position setting becomes easier. This has the advantage that it is possible to easily adopt a configuration in which the arc contacts or the conductive contacts slide against each other by the driving means.
