TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electromagnetic relay, and more particularly to a structure of an electromagnetic relay suitable for being configured as a hinge-type small electromagnetic relay for a vehicle.
[0002]
[Prior art]
In general, as an electromagnetic relay, an electromagnetic coil body is formed by attaching an iron core and a yoke to a coil spool around which an electromagnetic coil is wound, and an iron piece is hinged to a yoke of the electromagnetic coil body by a movable contact spring, and the electromagnetic coil is electromagnetically driven. There is a hinged electromagnetic relay in which an iron piece is configured to be able to contact and separate from an iron core of a coil body. In this relay, a movable contact is attached to a tip end of a movable contact spring, and a pair of fixed contacts is provided with respect to a contact frame portion of a coil spool such that a pair of fixed contacts are arranged on both sides of the movable contact in the movable direction. Are fixed, and a pair of coil terminal pieces connected to the electromagnetic coil are mounted on a part of the coil spool.
[0003]
In the above-mentioned electromagnetic relay, the movable contact spring has a yoke extension portion fixed to the yoke and arranged along the surface of the yoke, and a movable extension portion fixed to the iron piece and arranged along the surface of the iron piece. In addition, a bent portion is provided between the yoke extending portion and the movable extending portion, which is bent substantially at a right angle. The yoke is formed in an L-shape in the electromagnetic coil body, and the yoke extension of the movable contact spring extends along the surface of the yoke on the opposite side to the movable extension, and extends along the L-shape of the yoke. After being bent, it extends further and projects outside the case body to constitute a movable terminal piece.
[0004]
[Problems to be solved by the invention]
By the way, in the above-mentioned electromagnetic relay, the movable contact spring serves as a hinge joint member for rotatably attaching the yoke and the iron piece, and also has an elasticity for holding the movable contact and ensuring contact between the movable contact and the fixed contact. It is used as an elastic member having three functions as a terminal member having a movable terminal portion protruding from the inside of the relay to the outside of the case body. For this reason, the movable contact spring is required to have predetermined characteristics such as elasticity, durability, conductivity, rigidity, and soldering characteristics. Therefore, since it is necessary to use a specific material for the movable contact spring, it is difficult to reduce the material cost.
[0005]
On the other hand, since the movable contact spring is configured to extend along the surface of the iron piece and the yoke from the tip end holding the movable contact and further project to the outside of the case body to form a movable terminal portion, Since the outer periphery of the internal structure of the relay is surrounded in a U-shape, the use of movable contact springs increases even in the case of small relays, which increases material costs, but also the contact characteristics of movable contact springs, characteristics of hinges, etc. In order to adjust the thickness, a part of the material is formed to be narrow or wide, so that much of the material needs to be discarded, and there is a problem that the manufacturing cost of the electromagnetic relay is inefficient.
[0006]
Therefore, the present invention is to solve the above-mentioned problem, and the problem is to reduce the cost of material by making the movable contact spring smaller than before, and also to reduce the amount of waste and efficiently manufacture. It is intended to provide an electromagnetic relay.
[0007]
[Means for Solving the Problems]
In order to solve the above problem, an electromagnetic relay according to the present invention includes, inside a case body, an electromagnetic coil, an electromagnetic coil body including an iron core portion and a yoke portion, and magnetically connected to the yoke portion. A movable magnetic member that is configured to be able to contact and separate from the movable magnetic member, and a hinge portion that is configured to hold the yoke portion and the movable magnetic member so that the movable magnetic member can be brought into and away from the movable magnetic member, and is connected to a movable contact that operates with the movable magnetic member. A movable contact spring fixed to the yoke portion and extending along the surface thereof; and a movable extension spring fixed to the movable magnetic member and extending along the surface. A portion of the movable contact spring extends from the yoke extending portion to the movable extending portion side and passes through a region facing the hinge portion side end surface of the movable magnetic member, Stretch straight Characterized in that it is configured as a movable terminal piece portion that is drawn out through the base of the case body Te.
[0008]
According to the present invention, the movable terminal piece of the movable contact spring is configured to extend from the yoke extension to the movable extension, so that the surface of the electromagnetic coil body on the opposite side to the movable extension is provided. Since it is not necessary to extend the movable contact spring to the outside of the case body after extending the movable contact spring, the movable contact spring can be reduced in size without impairing the function of the movable contact spring, and the material cost can be reduced. In addition, since the movable terminal piece passes through the vicinity of the end of the movable magnetic member and is drawn out of the case body, even if the movable magnetic member attempts to move in the event of an impact or the like, the movable terminal piece cannot be moved. Since it is prevented by the base, it is possible to prevent damage or deformation of a portion of the movable contact spring that joins the movable magnetic member and the yoke, so that the shock resistance of the electromagnetic relay can be improved.
[0009]
In the present invention, the yoke portion and the movable magnetic member are hingedly joined to each other by the movable contact spring in a state of being orthogonal to each other, and the movable contact spring is orthogonally interposed between the yoke extension portion and the movable extension portion. The movable terminal piece portion is connected to the yoke extension portion, is formed so as to branch off from the movable extension portion, and is drawn out of the case body. Is preferred.

In the present invention, the movable extension portion and the yoke extended portion has a shape which is divided into each of the pair of connecting pieces to the bent portion side, the movable terminal piece portion, between the pair of connecting pieces it is preferably configured to extend from the yoke extended portion in. In this case, since the movable terminal piece is configured to extend from the yoke extension between the connection pieces, an unnecessary portion between the connection pieces in the movable extension is used as the movable terminal piece. Since the movable contact piece can be formed, the movable terminal piece can be formed by using a portion that has been conventionally discarded from a material as an unnecessary portion of the movable contact spring.
[0011]
In the present invention, a fixed terminal comprising a coil terminal piece connected to the electromagnetic coil and a fixed contact disposed opposite to the movable contact on a side from which the movable terminal piece is drawn out with respect to the electromagnetic coil body. Preferably, each piece is mounted. As an electromagnetic relay mounted on a circuit board, etc., the coil terminal piece and the fixed terminal piece are attached to the same side of the electromagnetic coil body as the movable terminal piece, so that the terminal piece of each terminal is also movable. It must be pulled out to the same side as the terminal strip.
[0012]
In the present invention, a pair of the fixed terminal pieces provided with a pair of fixed terminal pieces provided with fixed contacts arranged on both sides of the movable contact in the movable direction, and a contact frame portion for fixing the pair of fixed terminal pieces, It is preferable that the terminal pieces are press-fitted and fixed to the contact frame portion from directions orthogonal to each other. Since the pair of fixed terminal pieces are press-fitted and fixed to the contact frame from directions orthogonal to each other, a pair of mounting holes provided in the contact frame are also formed in directions orthogonal to each other. Even when the size of the contact frame is reduced, the rigidity is easily secured, and the positioning accuracy of the fixed contact is also easily secured. Therefore, the contact frame can be made compact, and the size of the electromagnetic relay can be reduced. it can.
[0013]
In the present invention, the pair of fixed contacts are disposed on both sides of a center side of the electromagnetic coil body and the case body side with respect to the movable contact, and include the fixed contacts disposed on a center side of the electromagnetic coil body. The fixed terminal piece is press-fitted and fixed to the contact frame portion in a direction parallel to a movable direction of the movable contact, and the fixed terminal piece having the fixed contact disposed on the case body side is a contact frame. It is preferable that the movable contact is press-fitted and fixed in a direction orthogonal to a movable direction of the movable contact. The fixed terminal piece provided with the fixed contact arranged on the center side of the electromagnetic coil, that is, on the inner side, is inserted deeper into the contact frame, so that the moving direction of the movable contact can be increased without increasing the size of the contact frame. When press-fitted and fixed in a direction parallel to the direction, the press-fit depth can be sufficiently ensured, and the fixed terminal piece provided with the fixed contacts arranged on the case body side, that is, the outside, is located on the outer surface of the contact frame portion. Although it is attached near the portion, the press-fitting depth can be ensured without increasing the size of the contact frame by being configured to be press-fitted and fixed in a direction orthogonal to the movable direction of the movable contact. Therefore, for each of the fixed terminal pieces, a sufficient press-fit depth can be obtained without increasing the size of the contact frame portion, so that the mounting strength and positional accuracy of the fixed contact can be sufficiently secured, and the contact frame portion can be formed. It can be kept compact and does not hinder downsizing of the electromagnetic relay.

[0022]
In the present embodiment, as shown in FIG. 1, a pair of inclined portions 10a that are formed obliquely are formed on the left and right upper portions of a case 10 that is formed in a box shape as a whole. In the internal structure of the present embodiment, since the contact structure and the terminal mounting portion are concentrated on the lower part of the electromagnetic coil body 20, the upper part of the electromagnetic coil body 20 is formed smaller than the lower part with a simpler structure. For this reason, by forming the inclined portion 10a, the electromagnetic relay is processed into a shape in which the upper portion of the case is squeezed to reflect the shape of the internal structure.
[0023]
In the present embodiment, the iron piece 31 is a magnetic pole 23a formed at the end of the iron core 23 by the elastic force of the movable contact spring 32 when no voltage is applied between the pair of coil terminal pieces 38, 38 (see FIG. 1), the movable contact 33 is in contact with a fixed contact 35 which is a normally closed contact. In this state, the circuit including the movable contact spring 32, the movable contact 33, the fixed contact 35, and the fixed terminal piece 37 is closed, and the terminal piece 32c of the movable contact spring 32 and the terminal piece 37c of the fixed terminal piece 37 Conducted. The terminal piece 32c of the movable contact spring 32 and the terminal piece 36c of the fixed terminal piece 36 are not electrically connected.
[0024]
On the other hand, when a predetermined voltage is applied between the coil terminal pieces 38, 38, the electromagnetic coil 22 is excited and the iron piece 31 is attracted to the iron core 23, so that the movable contact 33 comes into contact with the fixed contact 34 which is a normally open contact. . As a result, the circuit including the movable contact spring 32, the movable contact 33, the fixed contact 34, and the fixed terminal piece 36 is closed, and the movable terminal piece 32d of the movable contact spring 32 and the terminal piece 36c of the fixed terminal piece 36 are connected. Conduct. In addition, the movable terminal piece 32d of the movable contact spring 32 and the terminal piece 37c of the fixed terminal piece 37 become non-conductive. For convenience of illustration, FIG. 1 shows a voltage application state, and FIG. 4 shows a voltage non-application state.
[0025]
In the present embodiment, as shown in FIG. 7, as the shape of the movable contact spring 32, the movable terminal piece 32d extends from the yoke extension 32a to the movable extension 32b between the pair of connection pieces 32A and 32B. , And is drawn out of the case as it is. That is, the direction in which the movable terminal piece 32d of the movable contact spring 32 is pulled out is set to the opposite side to the conventional hinge type electromagnetic relay. Therefore, the terminal piece extends from the vicinity of the yoke mounting frame portion 21b of the coil spool 21 to the outside of the case as a result, and as a result, the movable contact spring 32 becomes an electromagnetic coil. Since the necessity is eliminated, the movable terminal piece 32d of the movable contact spring 32 is extremely short as compared with the related art, and as a result, the movable contact spring 32 itself is significantly short. It can be formed small. Therefore, the amount of material used to form the movable contact spring 32 can be significantly reduced. Further, since the movable terminal piece 32d is disposed between the connection pieces 32A and 32B, the unnecessary portion of the movable extension 32b between the connection pieces 32A and 32B is left partially. Can be formed. Therefore, the amount of material used can be further reduced, and unnecessary portions of the used material can be reduced to efficiently manufacture.
[0026]
As shown in FIG. 1, the movable terminal piece 32 d is inserted through the base 11 through a region facing the hinge part-side end surface of the iron piece 31 and is drawn out, so that the iron piece 31 has an impact. When the iron piece 31 is moved toward the yoke 24 (to the left in FIG. 1), it acts to prevent the iron piece 31 from moving. In other words, the bent portion 32c of the movable contact spring 32 moves together with the iron piece 31, but since the movable terminal piece 32d is attached to the yoke 24 and the base 11, even if the iron piece 31 collides between them, that of the iron piece 31 It acts to prevent the above movement. Therefore, damage to the movable contact spring 32 (particularly, deformation of the bent portion 32c) due to the movement of the iron piece 31 can be prevented, so that the shock resistance of the electromagnetic relay can be improved. This high impact resistance is particularly effective when used as an on-vehicle relay.
[0027]
Further, in the present embodiment, as shown in FIG. 4, the pair of fixed terminal pieces 36 and 37 are press-fitted and fixed to the contact frame 21 d, but the fixed terminal piece 36 is moved in the operation direction F <b> 1 of the movable contact 33. The fixed terminal strip 37 is press-fitted and fixed in a direction F2 substantially orthogonal to the operation direction of the movable contact 33. Therefore, since the pair of fixed terminal pieces 36 and 37 are press-fitted and fixed in the direction orthogonal to each other, the rigidity can be easily increased without forming the contact frame portion 21d large, so that the fixed contact can be easily obtained. It is possible to improve the positional accuracy of the positions 34 and 35, and it is possible to reduce the thickness of the contact frame portion 21d to reduce the size.
[0028]
In addition, the electromagnetic relay of the present invention is not limited to the illustrated example described above, and it is needless to say that various changes can be made without departing from the gist of the present invention.
[0029]
【The invention's effect】
As described above, according to the present invention, since the movable terminal piece of the movable contact spring is configured to extend from the yoke extension to the movable extension, the electromagnetic contact on the opposite side to the movable extension is provided. There is no need to extend the movable contact spring to the surface of the coil body and then pull it out of the case body. Therefore, the movable contact spring can be made small without impairing the function of the movable contact spring, and the material cost can be reduced. . In addition, since the movable terminal piece passes through the vicinity of the end of the movable magnetic member and is drawn out of the case body, even if the movable magnetic member attempts to move in the event of an impact or the like, the movable terminal piece cannot be moved. Since it is prevented by the base, it is possible to prevent damage or deformation of the portion of the movable contact spring that joins the movable magnetic member and the yoke, so that the shock resistance of the electromagnetic relay can be improved.
