Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic relay, and more particularly to a structure for mounting its coil terminals. 2. Description of the Related Art Conventionally, as a mounting structure of a coil terminal according to an electromagnetic relay, for example, a coil terminal is insert-molded in a flange portion of a spool, or a press-fit groove formed in an outer surface of the flange portion. It is conceivable to press-fit the middle part of the coil terminal from the side and attach it. [0003] However, as the size of the device is reduced, the distance from other internal components located around the coil terminal, for example, a movable iron piece or iron core, becomes shorter.
For this reason, the thickness of the flange portion of the spool for press-fitting the coil terminal becomes thin, and a sufficient press-fit allowance cannot be secured. As a result,
Since sufficient mounting strength cannot be secured, there is a problem that the coil terminals are likely to fall off during an assembly process such as coil winding work or inter-process conveyance. [0004] In view of the above problems, an object of the present invention is to provide an electromagnetic relay capable of preventing a coil terminal from falling off during an assembling process by securing a desired mounting strength. SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method in which an intermediate portion of a coil terminal located between an erect portion located at an upper end and a terminal portion located at a lower end is spooled. In the electromagnetic relay attached to the side end surface of the flange portion from the side, one end of the intermediate portion of the coil terminal is press-fitted into a press-fit groove provided on the side end surface of the flange portion as a press-fit portion, and the other end of the intermediate portion is As a caulking portion, a configuration is adopted in which a pair of caulking projections provided on the side end surface of the flange portion is press-fitted and fixed by caulking. According to the present invention, both ends of the intermediate portion of the coil terminal are supported on the side end surface of the flange of the spool by press-fitting and crimping, respectively, so that a high mounting strength can be secured. Also, it is possible to prevent the coil terminals from falling off during the assembly process. In particular, of the intermediate portion of the coil terminal, the press-fit portion located at one end and the caulking portion located at the other end are respectively assembled to the press-fit groove provided on the side end surface of the flange portion of the spool and the pair of caulking protrusions. is there. For this reason, since it is not necessary to form an elongated groove on the side end surface of the spool flange portion, the molding of the spool is simplified, and the thickness and the size of the spool can be reduced. Furthermore, there is no need to caulk the coil terminals themselves, and the coil terminals can be fixed by caulking the pair of caulking projections on the spool, making it easy to miniaturize and mold the coil terminals and simplify the work of assembling the coil terminals. The effect is that an electromagnetic relay with high productivity can be obtained. An embodiment of the present invention will be described below with reference to FIGS.

A protrusion is provided at the upper end of the intermediate portion 27c located immediately below to form a press-fit portion 27d. The press-fitting portion 27d is press-fitted into a press-fitting groove 21b provided on the outer surface of the flange portion 21, and a part of the intermediate portion 27c is provided on a pair of caulking protrusions 21c, After press-fitting and positioning between the protrusions 21c, the caulking projections 21c, 21c are fixed by hot or cold caulking. Then, after winding the coil 24 around the body of the spool 23 (FIG. 4), the lead wire is wrapped around the buckle 27a of the coil terminal 27 and soldered. The method of fixing the coil terminal 27 is not limited to the above-described method. For example, the lower end of the intermediate portion 27c may be press-fitted as the press-fit portion 27d, while the upper end of the intermediate portion 27c may be fixed by caulking. Further, the press-fitting portion 27
d may be fixed by caulking, or

The sliding card 60 has a driving projection 64 projecting from the center of one end face, and a position regulating tongue piece 62a of the locking metal fitting 62 projecting from both side faces thereof, and the other end face center section. The protruding pressing tongue piece 63a of the locking metal fitting 63 and the long tongue portions 63b located on both sides of the pressing tongue 63 protrude from the locking tongue 63. Further, a positioning projection 61a which is engaged with the positioning projection 15 of the base 10 is provided on the inner side surface of the fitting hole 61. The long tongue 6 of the slide card 60
3b and 63b are connected to guide portions 53c and 53 of movable contact piece 53.
c, and the movable contact piece 53 is pressed by the pressing tongue piece 63a.
While pressing the upper end of the tongue pieces 62a, 62
The sliding card 60 is elastically engaged with the cutouts 32 of the movable iron piece 30 from above and assembled, so that the sliding card 60 is slidably supported by one touch. According to the present embodiment, the locking members 62 and 63 are insert-molded at both ends of the card 60. Therefore, even if the movable contact piece 53 generates heat, the card 60 is not easily deformed or warped. . Moreover, even when the card 60 slides, the card 60 is moved to the movable contact piece 53
, No abrasion powder is generated from the resin portion, and a contact failure due to the abrasion powder does not occur. Further, the locking fitting 63
Has a high melting point, so that the card 60 is not easily melted by heat, and the assembling is easy, so that there is an advantage that the productivity is improved. The case 70 has a box shape that can be fitted to the base 10 and has an annular projection 71 from the center of the ceiling surface.
Protrudes inward. Further, the case 70
It has a gas vent hole 72 at the edge near the upper surface corner, and has a projection 73 that can be cut off to form a gas vent hole to remove nitric acid gas generated during use. When the case 70 is fitted to the base 10 on which the internal components such as the electromagnet section 20 are assembled,
The lower end of the projection 71 contacts the upper surface of the frame 11 of the base 10 via the fitting hole 61 of the card 60 (FIG. 2). Then, a sealing agent (not shown) is injected into the bottom surface of the base 10,
After solidifying and sealing, and evacuating the internal gas from the gas vent hole 72, the gas vent hole 72 is melted by heat and sealed to complete the assembling operation. According to this embodiment, the position of the ceiling surface of the case 70 is regulated via the projection 71, and the ceiling surface of the case 70 does not bend even when an external force is applied to the upper surface of the case 70.
The operation of the card 60 is not hindered. Further, the protrusion 71
If the gate of the molding die is arranged on the axis of the above, there is an advantage that the flow of the molding resin is improved and the moldability is improved. The protrusion 71 provided on the case 70 is not limited to be brought into contact with the upper surface of the frame 11 provided on the base 10. For example, the protrusion 71 may be brought into contact with the spool 23 of the electromagnet section 20. Alternatively, a projection may be provided on the upper surface of the frame body 11 to make contact with the ceiling surface of the case 70. Further, notches may be provided in the card 60 instead of the fitting holes. Next, the operation of the electromagnetic relay having the above configuration will be described. When the electromagnet portion 10 is not excited, the card 60 is urged leftward in FIG. 2 by the spring force of the movable contact piece 53, but the positioning protrusion 61 a of the card 60 is 15
Since the position of the movable contact piece 53 is regulated, the movable contact 53
a contacts the fixed contact 51a with a predetermined contact pressure. A voltage is applied to the coil 24 so that the electromagnet section 10
Is excited, the magnetic pole portion 25a of the iron core 25 is
Is moved, the movable iron piece 30 rotates, and the movable iron piece 30
Presses the tip surface of the protrusion 64 provided on the card 60. For this reason, the sliding card 60 slides rightward in FIG. 2, and the pressing tongue 63 a of the card 60 presses the upper end of the movable contact piece 53. As a result, the movable contact piece 53 rotates, and the movable contact 53a switches from the fixed contact 51a to the fixed contact 52a. When the excitation of the electromagnet section 10 is released, the slide card 60 is pushed back by the spring force of the movable contact piece 53, so that the movable iron piece 30 rotates in the opposite direction to that described above, and the movable contact 53a is moved. The movable contact 53a is separated from the fixed contact 52a, but the protrusion 61a of the card 60 is locked to the protrusion 15 of the base 10 to regulate the position of the movable contact piece 53. Contact again,
Return to the original state.
