路への通電が行われる。Next, the operation of the conventional electromagnetic contactor shown in FIG. 5 will be described. FIG. 5 shows a state in which the fixed contact 10 and the movable contact 7 are in an open state and the main circuit is de-energized. Next, when the coil 3 is excited, the movable iron core 4 is attracted and the crossbar 6 connected to the movable iron core 4 is pulled down in the figure. When the cross bar 6 is lowered, the movable contact 7 is pushed down by the contact spring 8, the contact 7a of the movable contact 7 contacts the contact 10a of the fixed contact 10, and the main circuit is energized.

る。Even after the contact 7a of the movable contact 7 comes into contact with the contact 10a of the fixed contact 10, the movable iron core 4 and the crossbar 6 are further moved downward by a certain distance defined by the standard.
It is designed to crimp a and. The above-mentioned operation in which the movable iron core 4 and the crossbar 6 move downward after the contact between the contacts 7a and 10a is called overtravel. The purpose of this overtravel is to ensure contact between the contacts even if the contacts 7a and 10a are worn out, and to prevent fusion and wear of the contacts by ensuring contact. .

に小さくして保持力を向上させている。[Problems to be Solved by the Invention] The fixed contact 10 of the conventional electromagnetic contactor is formed in a substantially U shape as shown in FIG. It is inserted into the grooves 11a and 11b, incorporated as shown in FIG. 7, and held by utilizing the elasticity of the material of the fixed contact 10. In this case, the distance L 5 at the root portion between the lower member 10c and the upper member 10d of the fixed contact 10 is slightly larger than the distance L 1 between the lower groove 11a and the upper groove 11b of the base 11, If the distance L 6 at the tip portion between the lower member 10c and the upper member 10d of the contact 10 is set to be slightly larger than the distance L 1 between the grooves of the base 11, the insertion is easy but the holding force is weakened. The holding force is improved by making L 5 smaller than L 1 and L 6 smaller than L 1 .

それがあった。However, since L 5 is made smaller than L 1 , as shown in FIG. 7, the tip of the fixed contact 10 is lowered by the dimension m to the lower side of the figure, and the amount of overtravel is reduced by the dimension m. Therefore, there is a possibility that reliable contact may not be obtained.
