Conventionally, as a yoke fixing device for this type of relay coil, one described in Japanese Utility Model Application No. 115437/1983 is known. The device described in this publication has the lower end of the leaf spring fixed to the front surface of the yoke bent toward the side surface of the yoke to form a U-shape in plan. An elastic stopper piece that expands outward is provided at the upper part of both the left and right sides, a hole is bored in the lower part of the stopper piece, and the protrusions provided on both sides of the yoke are fitted into the hole. The spring is fixed to the yoke. On the other hand, a guide groove is provided vertically facing the inside of the left and right upright portions of the base, and an escape hole is further bored in this guide groove. Then, the stopper piece provided on the spring piece presses the guide groove to lower the yoke, and when the stopper piece descends to the position of the relief hole, the elastic restoring force of the stopper piece is applied. The yoke is fitted into the relief hole to fix the yoke to the base.

In the above conventional type, when the stopper piece presses against the guide groove and descends, the stopper piece is urged outward, so it acts as a kind of file and scrapes the guide groove, and the cutting waste is scattered. There are defects in that the function as a relay is degraded, and furthermore, the elastic restoring force of the stopper piece is degraded, the fixing strength of the yoke is weakened, and the quality of the product is also degraded. Therefore, a technical problem arises that must be solved in order to obtain stable fixing strength with the stopper piece and to fix the yoke of the relay coil to the base without deteriorating its function as a relay. The present invention aims to solve this problem.

In the present invention, a plate spring having a U-shape in plan view is fixed to the back surface of a yoke, an inverted-shaped cut is provided on both sides of the plate spring, and the area surrounded by the cut is formed into a stopper piece. , a tapered stepped portion and an escape hole are provided at the bottom of the guide groove of the base. Therefore, when inserting the yoke into the guide groove and trying to fix it, both sides of the leaf spring fixed to the side of the yoke are inserted into the wide part at the upper part of the guide groove at the same time as the yoke. Ru. However,
Since the lower end portions of the tongue pieces provided at the lower portions of both sides of the leaf spring are bent inward, insertion of the yoke into the guide groove can be carried out extremely easily and smoothly without any resistance.
In this way, when the yoke is inserted into the guide groove and pushed in, the tongue piece reaches the stepped part of the guide groove, and is pushed along the tapered surface of this stepped part, thereby causing the tongue piece to reach the stepped part of the guide groove. The piece is bent in the direction of the taper of the step. At this time, the stopper piece 5 connected to the tongue protrudes outward as a reaction to the operation of the tongue and fits into the relief hole of the guide groove. In this way, the yoke is fixed to the base smoothly, and furthermore, since the guide groove is not cut by the leaf spring when the yoke is inserted, and no debris is generated, the quality of the product is prevented from deteriorating due to the debris. Further, since there is no phenomenon of fatigue of the spring of the stopper piece, stable fixing strength can be obtained.

An embodiment of this invention will be described below in detail with reference to the accompanying drawings. For convenience of explanation, conventionally known configurations will also be explained at the same time. In FIGS. 1 to 3, the yoke 1 is shown in side view L.
It is shaped like a letter, and there are two mounting holes for the relay coil on the bottom.
The upper portion of the yoke 1 is provided with a notch 3 for an armature and a pushing piece. Then, a plate spring 4 having a U-shape in plan view is fixed to the back surface of the yoke 1 by appropriate means such as caulking. A stopper piece 5 is formed by making an inverted cut on both sides of the leaf spring 4, and a tongue piece 6 is hung from the lower part of the stopper piece 5. Note that the lower end of the tongue piece 6 is bent toward the yoke 1. Further, a spring 7 is provided by extending the central portion of the leaf spring 4 upward and bending its tip slightly forward. In FIGS. 4 and 5, the base 8 is molded from synthetic resin and has a base 9 that is rectangular in plan view.A yoke holding portion 10 is provided approximately in the center of the base 9, and the yoke Upright portions 11, 11 are provided upright on the left and right side surfaces of the holding portion 10. These standing parts 11, 11
Guide grooves 12, 12 into which the yoke 1 is to be fitted are provided facing each other on the inner surface of the yoke. Further, tapered stepped portions 13, 13 are provided near the upper portions of the guide grooves 12, 12, and the distance between the guide grooves 12, 12 at the upper portion of the stepped portions 13, 13 is set to the guide groove 12, 12 at the lower portion. , 12. Further, relief holes 14, 14 are bored in the upper portions of the stepped portions 13, 13. The position of the relief hole 14 is formed so that it is approximately at the same position as the stopper piece 5 when the yoke 1 is fitted into the guide grooves 12, 12. Further, a protrusion 1 for locking a case (not shown) is provided at the lower part of the outer surface of the upright portions 11, 11.
5, 15 are provided protrudingly, and terminal holes 16, 16, . . . are bored at appropriate positions in the base 9. 6 and 7 show the yoke 1 and the base 8.
To explain the installation procedure, first, both side edges of the yoke 1 are fitted into the guide grooves 12, 12 of the base 8 and pushed downward. Then, both sides of the leaf spring 4 are aligned with the guide groove 1.
2, 12 and descends, the tongue piece 6 comes into contact with the stepped portion 13 of the guide groove 12 and is pressed inward. Then, as a reaction to the inward bending of the tongue piece 6, the stopper piece 5 on the upper part of the tongue piece 6 projects outward and is fitted into the escape hole 14 of the guide groove 12. At this time, the bottom surface 1a of the yoke 1 comes into contact with the bottom surface of the base 8, and since both side edges of the yoke 1 are fitted into the guide grooves 12, 12 of the base 8, the yoke 1 is firmly fixed to the base 8. Moreover, since the stopper piece 5 is locked into the escape hole 14, it will not come off accidentally. In addition, the code 17 in Figure 7
is a relay coil attached to the bottom surface 1a of the yoke 1.

This idea works when fixing the yoke to the base.
Since the guide groove of the base is not cut by the spring piece fixed to the side surface of the yoke, no cutting waste is generated. Therefore, the yoke can be inserted very easily and smoothly along the guide groove without degrading the quality of the product due to the cutting debris. In addition, since the stopper piece is not pressed into the guide groove and fitted into the relief hole, the lower tongue piece does not fit into the tapered stepped part without causing the spring fatigue phenomenon. Since the stopper piece fits into the relief hole as a reaction to the diagonal bending along the yoke, stable fixing strength of the yoke can be obtained.
