DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic relay,
In particular, the present invention relates to a structure of an electromagnetic relay suitable for being configured as a hinge-type small electromagnetic relay for use in a vehicle.

[0002]

2. Description of the Related Art Generally, as an electromagnetic relay, an electromagnetic coil 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 attached to the yoke of the electromagnetic coil by a movable contact spring. There is a hinge-type electromagnetic relay in which an iron piece is hingedly connected to an iron core of an electromagnetic coil body so that the iron piece can be moved toward and away from the iron core. 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. Fixed terminal strip is attached,
A pair of coil terminal pieces connected to the electromagnetic coil are attached to a part of the coil spool.

In the above-mentioned electromagnetic relay, the movable contact spring is fixed to the yoke and arranged along the surface of the yoke, and the movable extension spring is fixed to the iron piece and arranged along the surface of the iron piece. And a bent portion that is bent substantially at a right angle between the yoke extension portion and the movable extension portion. 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 form a movable terminal piece.

[0004]

In the above-mentioned electromagnetic relay, the movable contact spring serves as a hinge joining member for rotatably attaching the yoke and the iron piece, and also holds the movable contact, and the movable contact and the fixed contact. It is used as an elastic member having elasticity for ensuring contact with the terminal member, and as a 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 elastic, durable,
Since predetermined characteristics are required for conductivity, rigidity, soldering characteristics, etc., there are restrictions on the materials used. Therefore, it is necessary to use a specific material for the movable contact spring, so it is difficult to reduce the material cost.

On the other hand, the movable contact spring is configured to extend from the tip end holding the movable contact along the surfaces of the iron piece and the yoke, and further project outside the case body to form a movable terminal portion. Therefore, the outer periphery of the internal structure of the electromagnetic relay is surrounded in a U-shape, so that even in the case of a small relay, the amount of use of the movable contact spring is increased and the material cost is increased, but the contact characteristics of the movable contact spring, the hinge part In order to adjust the characteristics of the electromagnetic relay, it is necessary to discard much of the material because it is partially formed to be narrow or wide, which is inefficient due to the manufacturing cost of the electromagnetic relay. is there.

Accordingly, the present invention has been made to solve the above-mentioned problem, and has as its object to reduce the cost of material by making the movable contact spring smaller than before, and to reduce the amount of waste to efficiently manufacture. It is intended to provide an electromagnetic relay capable of performing the above.

[0007]

In order to solve the above-mentioned problems, an electromagnetic relay according to the present invention comprises: an electromagnetic coil body having an electromagnetic coil, an iron core and a yoke inside a case body; A movable magnetic member that is electrically connected and configured to be able to contact and separate from the iron core portion, and a movable contact that holds the yoke portion and the movable magnetic member so as to be able to contact and separate from each other, and operates together with the movable magnetic member. A movable contact spring connected to the movable contact spring, the movable contact spring is fixed to the yoke portion, a yoke extension portion extending along the surface thereof, and fixed to the movable magnetic member, along the surface thereof. A movable extending portion that extends, and a part of the movable contact spring,
It is characterized in that it is configured as a movable terminal piece extending from the yoke extension to the movable extension and extending to the outside of the case body.

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 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 surface and then pull it out of the case body, the movable contact spring can be made smaller 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 blocked 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.

In the present invention, the yoke portion and the movable magnetic member are hingedly joined by the movable contact spring in a substantially orthogonal state, and the movable contact spring is provided with the yoke extension portion and the movable extension contact portion. The movable contact terminal portion is connected to the yoke extending portion, and is formed so as to branch off from the movable extending portion, so that the case body has It is preferable that it is drawn out.

In the present invention, the movable extension has at least a pair of connection pieces connected to the yoke extension, and the movable terminal piece is located between the pair of connection pieces. Is preferably configured to extend from the yoke extension. 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. Can be formed,
Conventionally, a movable terminal piece can be formed by using a portion that has been discarded from a material as an unnecessary portion of a movable contact spring.

In the present invention, the electromagnetic coil body includes 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 extended. It is preferable that the fixed terminal pieces are attached respectively. 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 piece is also movable. It must be pulled out to the same side as the terminal strip.

In the present invention, a pair of the fixed terminal pieces each having fixed contacts disposed on both sides of the movable contact in the movable direction, and a contact frame portion for fixing the pair of fixed terminal pieces are provided. It is preferable that the fixed terminal pieces are press-fitted and fixed to the contact frame from directions substantially orthogonal to each other. Since the pair of fixed terminal pieces are press-fitted and fixed to the contact frame portion from directions substantially orthogonal to each other, a pair of mounting holes provided in the contact frame portion are also formed in directions substantially orthogonal to each other. Therefore, it is easy to secure rigidity even if the contact frame is downsized, and it is also easy to secure the positioning accuracy of the fixed contact, so that the contact frame can be made compact and the electromagnetic relay can be downsized. be able to.

In the present invention, the pair of fixed contacts are disposed on both sides of a center of the electromagnetic coil body and the case body with respect to the movable contact, and the fixed contacts are disposed on a center side of the electromagnetic coil body. The fixed terminal piece having
The fixed terminal piece, which is press-fitted and fixed in a direction substantially parallel to the movable direction of the movable contact with respect to the contact frame portion and includes the fixed contact arranged on the case body side, is provided with the fixed terminal piece with respect to the contact frame portion. It is preferable that the movable contact is press-fitted and fixed in a direction substantially orthogonal to the movable direction of the movable contact. Since the fixed terminal piece having the fixed contact arranged on the center side of the electromagnetic coil, that is, more inside, is inserted deeper into the contact frame portion,
When the press-fitting is performed in a direction substantially parallel to the movable direction of the movable contact without increasing the size of the contact frame portion, a sufficient press-fitting depth can be ensured, and the fixing disposed on the case body side, that is, on the outside. The fixed terminal piece provided with the contact is attached near the outer surface of the contact frame, but is not press-fitted in a direction substantially perpendicular to the movable direction of the movable contact, so that the contact frame is not enlarged. , The press-fit depth can be ensured. 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.

In the assembling process of the present embodiment, after the above-described internal structure is completed, the base 11 is accommodated in the case 10 and the base 11 is attached to the case 1 with each terminal piece inserted into the terminal insertion hole.
After the fitting, the inner structure is sealed in the case body (consisting of the case 10 and the base 11) by applying a sealing resin to the outer surface of the base 11 and curing the resin.

In this embodiment, as shown in FIG. 1, a pair of inclined portions 10a which are formed obliquely are formed on the left and right upper portions of a case 10 which 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 above-mentioned inclined portion 10a, the electromagnetic relay is formed into a shape in which the upper part of the case is squeezed, reflecting the shape of the internal structure.

In the present embodiment, the iron piece 31 is moved by the elastic force of the movable contact spring 32 when no voltage is applied between the pair of coil terminal pieces 38, 38.
The movable contact 33 is in contact with a fixed contact 35, which is a normally closed contact, apart from the magnetic pole 23a (see FIG. 1) formed at the end of the third contact 3. In this state, the movable contact spring 32 and the movable contact 3
3, the circuit consisting of the fixed contact 35 and the fixed terminal strip 37 is closed, and the terminal strip 32c of the movable contact spring 32 and the terminal strip 37c of the fixed terminal strip 37 are electrically connected. Further, 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.

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
When the iron piece 31 is attracted to 3, the movable contact 33 comes into contact with a fixed contact 34 which is a normally open contact. Thereby, the movable contact spring 32, the movable contact 33, the fixed contact 3
4. The circuit consisting of the fixed terminal strip 36 is closed, and the movable terminal strip 32d of the movable contact spring 32 and the terminal strip 36c of the fixed terminal strip 36 conduct. Further, 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 state where a voltage is applied, and FIG. 4 shows a state where a voltage is not applied.

In the present embodiment, as shown in FIG.
a, the movable terminal piece 32d is made up of a pair of connection pieces 32A and 3
It is configured to extend toward the movable extension portion 32b side between 2B and to be drawn out of the case as it is. That is, the movable terminal piece 32d of the movable contact spring 32
Is set to the opposite side to the conventional hinge type electromagnetic relay. Therefore, as in the conventional case, the terminal piece extends long along the L-shape of the yoke 24 and is pulled out from the vicinity of the yoke mounting frame 21b of the coil spool 21 to the outside of the case. The body 20 is surrounded in a U-shape.) Since there is no need, the movable terminal piece 3 of the movable contact spring 32 is not required.
2d is much shorter than before, and as a result, the movable contact spring 32 itself is significantly shorter and can be made smaller. Therefore, the amount of material used to form the movable contact spring 32 can be significantly reduced. In addition, 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 parts of the used material can be reduced to efficiently manufacture.

Further, as shown in FIG.
2d is inserted through the base 11 through a region facing the end face of the iron piece 31 on the hinge portion side, and is drawn out. Therefore, the iron piece 31 is brought into the yoke 24 side by impact or the like (FIG. 1).
(To the left in FIG. 1), it acts to prevent the iron piece 31 from moving. That is, the bent portion 32c of the movable contact spring 32 moves together with the iron piece 31, but the movable terminal piece 3
Since 2d is attached to the yoke 24 and the base 11, even if the iron piece 31 collides between them, it acts so as to prevent the iron piece 31 from moving further. Therefore,
Damage to the movable contact spring 32 due to the movement of the iron piece 31 (particularly, deformation of the bent portion 32c, etc.) 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.

Further, in the present embodiment, as shown in FIG. 4, a pair of fixed terminal pieces 36, 3 are attached to the contact frame 21d.
7 is press-fitted and fixed.
3 is fixed by press-fitting in the operation direction F1.
Reference numeral 7 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 a direction orthogonal to each other, the rigidity can be easily increased without forming the contact frame portion 21d large. It is possible to improve the positional accuracy of the positions 34 and 35, and it is also possible to reduce the thickness of the contact frame portion 21d to reduce the size.

It should be noted that 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]

As described above, according to the present invention,
The movable contact piece of the movable contact spring extends from the yoke extension to the movable extension, so that the movable contact spring extends to the surface of the electromagnetic coil body opposite to the movable extension. Since it is not necessary to pull out the case body from the outside afterwards, it is possible to reduce the size of the movable contact spring without impairing its function, thereby reducing the material cost. Also, since the movable terminal piece is drawn out of the case body through the vicinity of the end of the movable magnetic member,
Even if the movable magnetic member tries to move in the event of an impact or the like, the movable magnetic member is hindered by the base of the movable terminal piece, so that the movable contact spring joining the movable magnetic member and the yoke can be prevented from being damaged or deformed. Therefore, the shock resistance of the electromagnetic relay can be improved.
