When the movable core 12 is attracted to the fixed core 15 by the excitation of the coil 10 and a driving force is generated, the movable shaft 12a fixed to the movable core 12 moves, and the relay is connected and fixed to the movable shaft 12a by the fixing bracket 26. The member CC relays the driving force, and the movable shaft is driven by the driving force greater than the spring force of the return spring 9 via the coupling portion 21 disposed in the relay member CC.
7 is driven, and the movable contact 6a of the movable contact 6 comes into contact with the fixed contact 5a. At this time, the pressing portion 17 of the relay member CC
Releases the lever 18a of the auxiliary contact portion 18, and releases the auxiliary contact portion 18.
Switches the operation . Thereafter, the movable shaft 7 is
The spring force of 8 is also applied, and it is pressed to the predetermined overtravel.

十分に引き伸ばされて消弧される。When the excitation of the coil 10 is cut off, the movable contact 6 is returned by the urging force of the contact pressure spring 8 and the return spring 9, and the movable contact 6a is separated from the fixed contact 5a. The movable iron core 12 also returns by a predetermined distance and returns to the original state until the movable core 12 is restricted by the housing DD. At this time, the relay member CC by Ri lever auxiliary contact portion 18 to the pressing portion 17 of the
18a is pressed again , and the auxiliary contact portion 18 operates in the opposite direction as when the contact is in contact. The arc generated between the contacts at the time of return is sufficiently extended toward both ends of the movable contact by the magnetic field of the magnetic means (not shown) and extinguished.

First, the return spring 9 is used between the time when the coil 10 is excited and the movable contact 6a comes into contact with the fixed contact 5a, and the return spring 9 is used during the overtravel after the movable contact 6a and the fixed contact 5a are closed. The coupling portion 21 is biased by the pressure spring 8 toward the drive member BB. For this reason, the positional relationship between the coupling portion 21 and the relay member CC remains unchanged.

て、一瞬に溶着接点が引き外される。Next, a description will be given of the operation of removing the welding when the contact welding is a slight welding when the welding occurs between the movable contact 6a and the fixed contact 5a due to an overcurrent load or an excessive rush current. When contact welding occurs, the movable contact 6 including the movable contact 6a is melted and fixed at one or two points to the fixed contact 5 including the fixed contact 5a while the coil 10 is excited. . When the excitation of the coil 10 is turned off in this state, the movable contact 6 attempts to return with the spring force of the contact pressure spring 8 and the return spring 9, but the movable contact 6 may operate because it is fixed to the fixed contact 5. No, the movable shaft 7 attempts to stop after returning only for the overtravel. However, since the movable shaft 7 is connected to the connecting portion 21 and is indirectly connected and fixed to the relay member CC, the movable shaft 12a, and the movable iron core 12, the movable shaft 7 has a maximum overtravel. The kinetic energy converted from the energy of the spring load at the time of overtravel by displacing from the state to the state where overtravel has disappeared is a conventional kinetic energy in which only the movable shaft 7 is independently displaced without being coupled to the relay member CC. The size is 10 to 20 times larger, depending on the shape and the material, because the mass is increased as compared with that of the material. The kinetic energy causes the welding contact to be instantaneously pulled off.
