善するために提案されたものである。 Figures 1 and 2 show the support state of the C spring of a conventional electromagnetic contactor. In the figures, 1 is a case, 2 is a fixed core, 3 is a coil, 4 is a movable frame, 5 is a movable core, and 6 8 is a movable contact, 8 is a fixed contact, and 9 is a C spring. However, both sides of the lever C spring engage with recesses provided on both sides of the movable frame 4 provided on the upper part of the movable iron core 5, and the curved part in the center
The C springs 9 are engaged with the recessed portions of the C springs 9, and the C springs 9 are mounted symmetrically. Such a configuration has the disadvantage that it is difficult to obtain a large slope F of the negative characteristic shown in FIG. 3 due to the relationship between the core stroke and the spring force of the C spring. The present invention has been proposed to improve the above-mentioned drawbacks.

る。 The present invention includes a movable frame having a movable contact and a movable iron core, a case having a fixed iron core and a fixed contact facing the movable iron core, both ends of which are engaged with the movable frame, and a curved part in the center is connected to the body. In an electromagnetic contactor having C springs that are engaged and supported in a high inclined state on the movable frame side, the above C springs are provided in the inner C spring and the outer C spring, and the distances between the fulcrums of the respective springs are different. The present invention relates to an electromagnetic contactor characterized in that a set of these C springs are arranged on both left and right sides.

離はＹとY′とが異なるように構成されているも
のであり、このバネが可動枠の上下方向の移動に
よつて伸ばされた場合の復帰力の勾配が異なつて
くる。 In FIG.
The inner C spring 9a engages with the recess 10a, and the outer C spring 9b engages with the recess 10b. Also case 1
Also, recesses 1a and 1b are provided on the inside and outside, and the inner C spring 9a engages with the recess 1a, and the outer C spring 9b engages with the recess 1b. In other words, the outer C spring and the inner C spring are configured such that the distances between the supporting points are different in Y and Y', respectively, and this spring is extended by the vertical movement of the movable frame. The gradient of the return force differs depending on the case.
第５図イは支点間距離Ｙ，Y′と鉄心のストロ

を用いた場合の復帰力を示す。 FIG. 5A shows the relationship between the distances Y, Y' between the supports and the stroke X of the core, and FIG. 5B shows the relationship between the core stroke X and the return force. In the figure, A shows the return force by the C spring 9a, B shows the return force by the C spring 9b, D shows the total return force, and E shows the return force when a conventional single spring is used.
第６図は本発明の実施例を示す。 FIG. 6 shows an embodiment of the invention.
叙上のように本発明のＣバネは左右夫々２本づ
つのバネを用い、夫々のバネの支点間距離を異な
らしめることにより、接点のオフ時の復帰力は従
来の場合より大きく、オフ時の復帰力を小とする
ことができる。 As mentioned above, the C-spring of the present invention uses two springs on each side, and by making the distance between the fulcrums of each spring different, the return force when the contact is off is greater than in the conventional case, and when the contact is off, The restoring force can be made small.
