[Prior Art] FIG. 8 shows a conventional electromagnet structure in which a coil 5 is wound around the outer periphery of a coil frame 3 and each piece 1a of a yoke 1'and an armature 2'having a substantially U shape is formed. , 2a are both inserted into the insertion hole 4 of the coil frame 3. The other pieces 1b and 2b of the yoke 1'and the armature 2'are both located outside the coil 5. The other piece 2b of the amateur 2'is swingably pivoted on the outside of the other piece 1b of the yoke 1 '.
The inner surface of the tip portion of the piece 2a of the amateur 2'of the magnetic pole surface 6 of the piece 1a is attracted. A piece 2a of the armature 2'is loosely fitted in the insertion hole 4 of the coil frame 3, and the armature 2'swings in response to the excitation of the coil 5 as indicated by the arrow in the figure. In the case of such a conventional example, since the piece 2a of the armature 2'is located in the insertion hole 4 of the coil frame 3, a large stroke of the piece 2a cannot be taken.
There is a problem that it is difficult to effectively transmit the force of the electromagnet to the spring. That is, the mounting position of the card becomes difficult. Further, in order to make the stroke of the contact attached to the armature 2 ′ large, it is necessary to make the cross-sectional area of the insertion hole 4 of the coil frame 3 large. There is a problem that 5 is difficult to wind and the magnetic efficiency is deteriorated. It should be noted that FIG. 7A shows the non-excitation state, and FIG. 7B shows the excitation state.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a sectional view of the entire relay, in which a coil frame 3 around which a coil 5 is wound is arranged on the outer periphery of a base 7. One piece 1a of the yoke 1 formed in a substantially U shape is inserted into the insertion hole 4 in the coil frame 3, and the other piece 1b is located outside the coil 5. The piece 2a of the armature 2 formed in a substantially U-shape is located inside the insertion hole 4 of the coil frame 3 and is pivotally supported outside the piece 1a of the yoke 1 so as to be swingable. The other piece 2b of the amateur is located outside the coil 5 and is arranged inside the other piece 2a of the yoke 1. That is, the yoke 1 and the armature 2 have a structure in which the respective pieces 1a, 2a and 1b, 2b are alternately fitted.

The card 8 that is pressed against the armature 2 has its fulcrum 8a located in the groove 9 that is recessed in the base 7, and the contact spring 10 is pressed through the projection 8b that is integrally projected on the card 8. I am trying to do it. Both the contact springs 10 and 11 are embedded in the base 7, and the ends thereof project from the base 7 to form terminals. Further, the contact points 12 and 13 facing each other are fixed to the tips of the contact point springs 10 and 11, respectively.

Since the yoke 1 and the armature 2 are alternately fitted in this way, the U-shaped bent portions of both the yoke 1 and the armature 2 can be made larger than in the conventional case in the same volume, and the parts can be easily manufactured. is there. Further, the coil 5 is excited so that the armature 2 becomes the magnetic pole surface 6 of the yoke 1.
Since the card 8 is attracted to and pushes the card 8, and the contact spring 10 is further pushed by the card 8, that is, a force is generated in the direction of pushing the contact spring 10, the force can be transmitted by the card 8 having a simple shape. Further, as compared with FIG. 8, the insertion hole 4 of the coil frame 3 can be made smaller, the winding amount of the coil 5 can be increased, and high sensitivity can be obtained.

By the way, the protrusion 8c of the card 8 is pressed and driven by the amateur 2, and the rotation locus of the contact surface between the amateur 2 and the card 8 is as shown in FIG. The rotation locus of the contact surface between the card 8 and the contact spring 10 by the portion 8b is as shown in (b), and the rotation locus of the contact spring 10 is as shown in (c). Here, the fulcrum portion 10a of the contact spring 10 is a portion embedded in the base 7. The armature 2 and the card 8 are not fixed, but the fulcrum portion 8a of the card 8 is provided near the fulcrum portion 10a of the contact spring 10. Then, by making the rotation locus (C) of the contact spring 10 and the rotation locus (B) of the card 8 into substantially the same circular center,
That is, by making the moving direction of the card 8 as close as possible to the contact driving direction, it is possible to provide a highly sensitive and stable relay. Here, considering the case where the card 8 is fixed to the armature 2 as shown in FIG. 2, the rotation locus of the card 8 is as shown in FIG. The difference in the locus is significantly different from that of), so that the friction between the card 8 and the contact spring 10 is large, resulting in loss of efficiency and instability of characteristics. Therefore, by configuring as shown in FIG. 1, a sliding friction between the card 8 and the amateur 2 is newly added, but the overall sliding amount is reduced, and therefore, the friction is reduced and the friction is reduced as described above. (Reduction of force in unnecessary direction) makes it possible to stabilize characteristics with high sensitivity.

Therefore, as shown in FIGS. 1 and 3, the contact spring 11
A rib 14 is integrally formed on the lower surface of the base 7 where it is press-fitted and fixed to the base 7, and the rib 14 causes a gap between the upper surface of the base 7 and the lower surface of the contact spring 11 as shown in FIG. 3 (b). Adhesive cutting is performed by providing S 1 and floating the contact spring 11 from the base 7. The gap S 1 is, for example, 0.2 to 0.3 mm.
And the gap is. Further, as shown in FIG. 3 (a), a slit 15 is provided at the position of the contact spring 11 between the portion into which the contact spring 11 is press-fitted and the other portion, and the slit 15 also cuts the adhesive. Are doing. With this configuration, it is possible to form a stable relay without the dimensional change of the contact position due to the adhesive seal. The same applies to the contact spring 10.

By the way, in order to improve the noise resistance performance between the contact portion of the relay and the coil 5, it is necessary to increase the spatial distance between the contact portion and the electromagnet portion. However, if the distance between them is simply increased, the shape is generally increased even if the noise resistance is high. Therefore, in the present embodiment, the yoke 1
On the side opposite to the magnetic pole surface of the other piece 1b, the tip portion with a low magnetic flux density is cut according to the shape of the contact spring 10 to reduce the stray capacitance, and this cut surface is the same distance from the contact spring 10. The slope 16 is kept at. That is, the inclined surface 16 and the contact spring 10 are substantially parallel to each other, and the spatial distance between the contact portion and the electromagnet portion is substantially the same. The card 8 located between the contact portion and the electromagnet portion is made of a non-dielectric material or formed as thin as possible. With such a configuration, the noise resistance performance is most improved in the same volume, and therefore, a compact relay having high noise resistance performance can be configured.

Further, in this relay, as shown in FIG. 1, a wall 17 is integrally provided between the armature 2 and the coil 5 so as to project from the base 7, and the wall 17 is not excited by the armature 2 (NC side).
I'm aiming for. That is, the size of the abutting position of the armature 2 is easily determined with respect to the magnetic pole surface of the yoke 1, and therefore the accuracy of the magnetic pole spacing is improved. Further, as will be described later, the wall 17 eliminates the possibility of the coil 5 and the armature 2 hitting each other when the armature 2 is inserted into the coil frame 3. Therefore, the stable magnetic pole spacing stabilizes the relay characteristics and shortens the adjustment process.
Further, disconnection defects of the coil 5 can be reduced.

Then, the hinge spring that is crimped to the amateur 2
Although the fixed end side of 18 is press-fitted into the coil frame 3, the tip end of the press-fitting piece 19 is inserted into the insertion hole 4 of the coil frame 3 as shown in FIG. When the projection 20 hits the step 22 of the insertion hole 4, the press-fitting piece 19 is pressed downward. Due to this pressing force, the hinge spring 18 is urged downward, the piece 2a of the amateur 2 is pressed downward, and the yoke 1
It is pressed against the upper surface of the tip of the piece 1a. The rib 21
Is in elastic contact with the inner wall surface of the insertion hole 4. When the armature 2 is inserted into the insertion hole 4, as shown in FIG. 7, the wall 17 for correcting the blurring of the tip of the other piece 2b of the amateur 2, that is, for guiding the other piece 2b is provided. It suffices if the wall 17 is as long as the length for guiding the other piece 2b. FIG. 5 shows a sectional view as seen from above at this time. In FIG.
The solid line of the hinge spring 18 shows the natural position before press fitting,
The broken line shows the position when press-fitting. The hinge point of the armature 2 is pressed against the yoke 1 by the difference between the solid line and the broken line. Incidentally, Y in FIG. 1 indicates a hinge point. With this configuration, the hinge spring fixed to the amateur 2
Since the hinge point of the armature 2 can be fixed only by press-fitting 18 into the insertion hole 4 of the coil frame 3, the assembly is easy, and since the press-fitting method is employed, there is no deformation of the hinge spring 18 and the hinge spring 18 The pressing force of the hinge point due to is stable, and therefore the characteristics of the relay are stable.
