In the on state, the contact 4 and the second contact 3 are in contact, and the two orphan contacts 10 are separated by a predetermined gap, and the disconnection is described next. When the Japanese is over-current, when the current is detected, the relay will be triggered by the opening and closing mechanism. The second movable member 5 will be bombed by the inviting spring 14. The thrust is centered in the clockwise direction, such as the first contact: the contact with the second orphan contact 10. At this time, the second ==: between the two contacts and the first arc contact 9 and the second contact 2 The contact 2 is further pulled up by the opening and closing mechanism portion 300, the second point 3 is slightly separated from the second point 3, and an arc is generated between the two contacts to cause the first pass to the opener - (4) the action is further advanced: In the state in which the contact element 9 and the second arc contact member are connected to each other, the i-th contact point 4 is greatly increased from the second contact point 3; the arc between == ” is greatly elongated. The main current of the current is moved to the contact point of the first individual contact member 9 and the first contact member 1G due to the increase in the second resistance of the electric element. When the opening and closing mechanism portion _ $进进:时时' then the rotation of the movable member 5 is restricted by the stopper pin 17, ζ = movement 6 320439, 10 200924003 'shown' to make the i-th arc contact 9 and the second arc Piece 'raw separation. Then, the arc generated between the arc contact 9 and the arc is attracted to the arc extinguishing chamber 18 to be arc-extinguished. In the case of the cow, for example, when the electromagnetic current of each of the flexible conductors 15 is generated by the large current due to the large current, the rotational force that increases the contact pressure of the contact acts on the movable member force system as / The ground acts to move the movable member 5 to the side of the opening and closing mechanism 胄 _, which is even before the operation of the closing mechanism unit 300. Elastic deformation occurs in the direction in which the contact arm 7 is lifted, two =. . It also opens and closes the direction of the mechanism. Further, the movable member is rotated in the clock direction, and the first arc contact member 9 is rotated until the disc is in the forward direction to increase the same state as in the fifth diagram.) m arc: the contact member W is in contact with the arc contact member H), and the contact point is The direction in which the second contact 4 and the second contact 3 are opened is applied to the movable member month: as shown in the figure, the first arc contact 9 is made to be the first; 10 The inclined coil spring 12 is flattened and displaced. After the 弧2 arc contact, when the relay is relayed, it will be used as a sailor, and the keeper will be mobilized to open the closing mechanism 300 P & contact arm 7. With this pull-up, the second contact 4 is slightly T 300, and the arc electrical contact 3 is opened between the two contacts, and the pull-up action of the advance step is performed under the second 'W maintain contact, the second connection Point 4 from the =2 arc contact produces an arc between the contacts that is pulled sharply: the arc is greatly removed, the arc resistance is increased, so that the main current is elongated due to the electric lone, and the electric private is in the arc contact 9 and the second Arc connection 320439 11 200924003 .
