Field of the Invention The present invention relates to a so-called balance armature type polarized relay in which an armature is swingably movable about a central portion as a fulcrum. 2. Description of the Related Art As this type of polarized relay, there is one having a configuration shown in FIGS. It has an iron core A wound with coils so that both ends become magnetic pole portions A 1 and A 2 , a permanent magnet B disposed between the magnetic pole portions A 1 and A 2 of the iron core A, and a central portion. The armature C is pivotally supported on a permanent magnet B and both ends in the longitudinal direction are attracted and released to both ends A 1 and A 2 of an iron core A, respectively, and a movable contact D 1 is provided at both ends. a pair of movable spring D which is integrally fixed to a central portion so that substantially along parallel on both sides of the armature C with an insulator D 2 in the longitudinal direction of the armature C provided, fixed movable contact D 1 is approaching and moving away from A base E provided with a contact E 1 , and a hinge spring piece F protruding from a substantially central portion of the movable spring D is fixedly supported by a fixing surface G 1 of a support piece G provided on the base E. I have. More specifically, as shown in FIG. 6, the hinge spring piece F is extended from a substantially central portion of the movable spring D, and then at a substantially central position with respect to the movable spring D through a meandering portion in the middle. and it reaches the tip portion F 1 on the same plane Te. Then, the tip portion F 1 of the hinge spring piece F is fixed by welding on the fixing surface G 1 of the supporting pieces G of the base E lying parallel, thereby, the movable spring D is connected to the support piece G It is electrically connected to the common contact terminal G 2 that is led to the outside. Next, the operation will be described. When the coil is energized, one end of the armature C has an iron core A according to its magnetization direction.
Is attracted to one of the magnetic pole portions A 1 and A 2 at both ends and swings around the central portion as a fulcrum, and even if the coil is turned off, the state is maintained by the holding and attracting force of the permanent magnet B, and the coil is turned on. When the direction is reversed, the armature C is similarly inverted and oscillated, and returns to the original state. As described above, this polarized relay is of a so-called balance armature type in which the armature C is swingably movable about the center portion as a fulcrum, and is provided on the movable spring D in response to the armature C. As the movable contact D 1 comes into contact with and separates from the fixed contact E 1 , the hinge spring piece F is twisted by the swing of the armature C, which acts as a spring load on the armature C 1. FIG. 7 shows the above-mentioned operation state. The horizontal axis indicates the stroke of the armature C, and the vertical axis indicates the spring load and the attractive force acting on the armature C. Since the movable spring D and the hinge spring piece F are arranged symmetrically with respect to the central portion which is the fulcrum of the swinging armature C, the movable spring load Q 1 (broken line) and the hinge spring load Q 2 (solid line) Further, the total load Q 0 (dashed line) obtained by adding them passes through the center S 0 of the stroke and performs bistable operation. If this is to be performed in a monostable operation, a non-magnetic plate having a thickness t is attached to one of the magnetic pole portions A 1 and A 2 at both ends of the iron core A, for example, on the side of the magnetic pole portion A 1 . As shown by the oblique lines in FIG. 7, since there is a gap corresponding to the plate thickness t on the magnetic pole portion A 1 side and the attraction force is cut, the holding attraction force by the permanent magnet B is reduced by turning off the coil. if Sagare to return the suction force P becomes smaller than the full load Q 0 at the magnetic pole portion a 1 side, so that the return. [0007] The present invention is to provide a in the conventional polarized relay as described above, the movable spring-loaded Q 1 and hinge spring loaded Q 2
Since passing through the center S 0 of the stroke of the armature C, and so as to monostable operation, in order to cut one side of the suction force of the both end magnetic pole portion A 1, A 2 of the iron core A, its It is necessary to attach a non-magnetic plate to the magnetic pole part, which increases the number of parts and is troublesome. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a polarized relay which can be easily made into a monostable operation type. [0009] In order to solve the above-mentioned problems, a polarized relay according to the present invention comprises an iron core on which a coil is wound so that both ends become magnetic pole portions, and a magnetic pole of the iron core.

From being in a state the hinge spring piece is fixed to the fixing surface of the support piece, already produce twisting, when the direction in which the armature swings against its twisting power, min the twisting force Since the spring load increases only when the coil is de-energized, the total load becomes larger than the holding and attracting force of the permanent magnet and returns in the opposite direction. An embodiment of the present invention will be described below with reference to FIGS. Numeral 1 is an iron core, and both legs are formed in a substantially U-shape as magnetic pole portions 1a and 1b of a magnetic material, and a coil is wound via a coil bobbin. Numeral 2 denotes a permanent magnet which is formed in a flat plate shape and whose both ends in the longitudinal direction are N-poles of the same polarity, and whose center is magnetized to an S-pole of a different polarity. And both ends are iron core 1
Are installed so as to contact the inner surfaces of the magnetic pole portions 1a, 1b at both ends of the
The iron core 1 has one polarity N due to both ends of the permanent magnet 2.
Magnetized to poles. Reference numeral 3 denotes a base formed by integrally molding an iron core 1 around which a coil is wound and a permanent magnet 2 with a synthetic resin to form a rectangular parallelepiped. At this time, the magnetic pole portions 1a and 1b at both ends of the iron core 1 are exposed on one plane, and fixed contacts 3a are provided at four corners thereof, and fixed terminal pieces 3b connected to the fixed contacts 3a and connected to the coil. The coil terminal strip 3c, the support strip 3d provided in the recess at the center on both sides in the longitudinal direction of one plane, and the common terminal strip 3e connected thereto are integrally formed by a conductive plate. The upper surface of the support piece 3d is crushed so that both ends have a step and the center is inclined in the longitudinal direction of the base 3. This inclined central part is
The fixing surface 3f is used to fix a hinge spring piece 5b described later. Reference numeral 4 denotes an armature, which is formed of a magnetic material and is formed in a substantially rectangular flat plate shape so that both ends in the longitudinal direction can face the magnetic pole portions 1a and 1b of the iron core 1. Reference numeral 5 denotes a movable spring, which is formed of a thin plate spring material such as a copper alloy and has a long shape. A movable contact 5a which comes into contact with and separates from the fixed contact 3a is fixed to both ends of the movable spring. The central portion of the armature 4 is fixedly supported by an insulator 4a formed integrally with the central upper surface of the armature 4 on both sides in the width direction of the armature 4 so as to be substantially parallel to the direction. From the center, a hinge spring piece is provided.
5b is protruded. More specifically, as shown in FIG.
After meandering in the longitudinal direction and the plate thickness direction of the movable spring 5, the movable spring 5 reaches a substantially central position with respect to the movable spring 5 and reaches a distal end portion on the same plane. The tip of the hinge spring piece 5b is shown in FIG.
As shown in FIG. 5, the support piece 3d is fixed by welding along the inclined fixing surface 3f, and at this time, the hinge spring piece 5b is twisted in accordance with the inclination of the fixing surface 3f. In this way, the movable spring 5 is electrically connected to the common terminal piece 3e extending to the outside from the support piece 3d, and the armature 4 is pivotally supported at its central portion on the permanent magnet 2 so as to be swingable. Both ends in the longitudinal direction are magnetic poles 1a and 1b at both ends of the iron core 1.

The horizontal axis indicates the stroke of the armature 4 and the vertical axis indicates the spring load and the attractive force acting on the armature 4. Since the movable spring 5 which are arranged symmetrically with respect to the central portion which is the fulcrum of the armature 4 swings, the movable spring-loaded Q 1 (broken line) whereas through the center S 0 of the stroke, the hinge spring Since the torsional force is generated on the piece 5b, its hinge spring load Q 2 (solid line) is
1a side is shifted to be larger, whereby the total load Q 0 (dashed line) obtained by adding the movable spring load Q 1 and the hinge spring load Q 2 is also the same as the hinge spring load Q 2.
The state is shifted to increase the 1a side. Then, when the off energization of the coil at the magnetic pole section 1a side, if Sagare to return the suction force P holding the suction force of the permanent magnet 2 is smaller than the full load Q 0, so that the return. In such an electromagnetic relay, as described above, the fixing surface 3f of the support piece 3d is formed so as to be inclined with respect to the hinge spring piece 5b , and the tip of the hinge spring piece is inclined with respect to the support piece.
In this case, a monostable operation is achieved just by being fixed along the fixed surface.In order to cut the attraction force on one side of the magnetic poles at both ends of the iron core, a non- Since there is no need to attach a magnetic plate, the number of parts does not increase and the work can be easily performed.
