ムーズに排出する。 An embodiment of the present invention will be described below based on the drawings. 1 is an outer shell consisting of a base 2 and a cover 3. 4 is a fixed contact, and 5 is a movable contact that is brought into contact with and separated from the fixed contact 4 by operating an opening/closing mechanism (not shown). 6 is a terminal portion for connecting external electric wires. 7 is a vertical piece 7 by bending the magnetic plate into an L shape.
This is an arc runner in which projections 7b are formed on both ends of the upper part of a, and a projection 7d is formed on the back side of the horizontal piece 7c at approximately the center. The cover 3 presses the horizontal piece 7c to abut the fixed contact 4, and the protrusion 7d of the horizontal piece 7c fits into the hole 4a of the fixed contact 4 and is fixed.
Incidentally, the distance between the protrusions 7b provided at both ends of the upper part of the vertical piece 7a of the arc runner 7 and the movable contact 5 is approximately equal, and the vertical piece 7a serves as a partition between the terminal portion 6 and the inside of the outer shell 1. There is. Reference numeral 8 designates an exhaust hole provided in the cover 3. The exhaust hole 8 is provided near the upper end of the vertical piece 7a of the arc runner 7, and is used to smoothly discharge high temperature and high pressure gas accompanying the arc generated when the movable contact 5 is opened. Discharge.

When the movable contact 5 is separated from the fixed contact 4, first, as shown in FIG. An arc f is generated between the movable contact 9 and the fixed contact 10 of the fixed contact 4. Thereafter, as the movable contactor 5 separates, the arc f is extended by the arc runner 7 as shown in FIG. 4B. When the separation is completed, the contact moves between the movable contact 5 and the upper part of the vertical piece 7a of the arc runner 7, as shown in FIG. 4C. At this time, as shown in FIG. 5, the arc f is divided between the projections 7b of the movable contact 5 and the arc runner 7, and is quickly extinguished.

い。 The present invention is not limited to the above-mentioned embodiments; for example, any fixing method may be used as long as the arc runner 7 is made of an L-shaped magnetic material and the horizontal piece 7c is in contact with the fixed contact 4. In addition, an exhaust hole was provided near the top of the vertical piece 7a of the arc runner 7, but this was done in order to smoothly exhaust the high-temperature, high-pressure gas accompanying the arc and further improve the cutting performance, so the exhaust hole was not necessary. You can set it up accordingly.

る。 As described above, according to the present invention, the magnetic material is formed into an L-shape and the arc runner 7 is added, which has protrusions 7b at both ends of the upper part of the vertical piece 7a. The arc that occurs is quickly extinguished by being transferred between the movable contact 5 and the upper part of the vertical piece 7a of the arc runner 7, and since the protrusions 7b are provided at both ends of the upper part of the vertical piece 7a, the arc is transferred between the movable contact 5 and the upper part of the vertical piece 7a of the arc runner 7. Since the arc is divided between the two, the arc can be extinguished more quickly, and the shearing performance can be improved. In addition, since the arc quickly moves between the movable contact 5 and the protrusions 7b provided at both ends of the upper part of the vertical piece 7a of the arc runner 7 and is extinguished, there is excellent effect such as less wear and tear on the contacts and a longer life. .
