An electromagnetic relay disclosed in Patent Literature 1 includes a shielding member that shields an arc generated between a movable contact and a fixed contact. The blocking member includes a blocking wall. The shielding wall suppresses the arc from circling the movable contact piece.

JP 2020-80256 A

In the electromagnetic relay of Patent Document 1, the positional relationship between the movable contact piece and the blocking wall changes as the movable contact piece moves when opening and closing the contacts. Therefore, the positional relationship between the movable contact piece and the shielding member may not be stable, and a stable shielding effect may not be obtained.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electromagnetic relay capable of obtaining a stable breaking effect.

An electromagnetic relay according to one aspect of the present invention includes a first fixed terminal, a movable contact piece, a movable member, and a first blocking wall. The first fixed terminal includes a first fixed contact. The movable contact piece includes a first movable contact facing the first fixed contact. The movable member holds the movable contact piece. The movable member is movable in movement directions including a first direction from the first movable contact to the first fixed contact and a second direction from the first fixed contact to the first movable contact. The first blocking wall is made of an insulating material. The first blocking wall is arranged in the second direction with respect to the first movable contact. The first blocking wall is fixed to the movable member and extends in the longitudinal direction of the movable contact piece from the movable member toward the first movable contact and in the moving direction of the movable member.

In this electromagnetic relay, the first blocking wall is arranged in the second direction with respect to the first movable contact. That is, the first blocking wall is arranged on the side opposite to the side on which the movable contact of the movable contact piece is arranged. Thereby, the arc generated between the first fixed contact and the first movable contact can be suppressed by the first shielding wall from going around the movable contact piece. Also, the first blocking wall is fixed to the movable member that holds the movable contact piece. As a result, the positional relationship between the movable contact piece and the first blocking wall is stabilized, so that a stable blocking effect can be obtained by the first blocking wall.

The movable contact piece may be fixed to the movable member. In this case, the positional relationship between the movable contact piece and the first blocking wall is further stabilized.

The first blocking wall may extend to the first movable contact in the longitudinal direction of the movable contact piece. In this case, a more stable blocking effect can be obtained by the first blocking wall.

The first blocking wall may extend in the longitudinal direction of the movable contact piece to one end of the movable contact piece in the longitudinal direction. In this case, a more stable blocking effect can be obtained by the first blocking wall.

The first blocking wall may include an inclined portion against which an arc generated between the first fixed contact and the first movable contact hits. The inclined portion may be inclined with respect to the moving direction of the movable contact piece when viewed from the longitudinal direction of the movable contact piece. In this case, since the contact range between the first shielding wall and the arc increases, the arc extinguishing performance can be enhanced.

The first blocking wall may have an inverted triangular shape that widens in the second direction when viewed from the longitudinal direction of the movable contact piece. Also in this case, since the contact range between the first shielding wall and the arc increases, the arc extinguishing performance can be improved.

The first blocking wall may include an extension against which an arc generated between the first fixed contact and the first movable contact strikes. The extending portion may extend in a direction orthogonal to the moving direction of the movable member. Also in this case, since the contact range between the first shielding wall and the arc increases, the arc extinguishing performance can be improved.

The first blocking wall may be T-shaped when viewed from the longitudinal direction of the movable contact piece. Also in this case, since the contact range between the first shielding wall and the arc increases, the arc extinguishing performance can be improved.

The first blocking wall may include at least one through-hole passing through the movable contact piece in the lateral direction. In this case, it is possible to effectively suppress the retention of high-temperature gas generated by the arc.

At least one through-hole may be slit-shaped. Also in this case, it is possible to effectively suppress the retention of the high-temperature gas generated by the arc.

The first blocking wall may be integrally formed with the movable member. In this case, the number of parts can be reduced.

The first blocking wall may be separate from the movable member. In this case, the degree of freedom in designing the first blocking wall is increased.

The first blocking wall may be displaced in the lateral direction of the movable contact piece with respect to the first movable contact when viewed from the longitudinal direction of the movable contact piece. In this case, when the electromagnetic relay has polarities, the arc can be greatly extended with one polarity.

The electromagnetic relay may further include a second fixed terminal including a second fixed contact, and a second blocking wall made of an insulating material and fixed to the movable member. The movable contact piece may further include a second movable contact facing the second fixed contact. The second blocking wall may extend longitudinally from the movable member toward the second movable contact and extend in the moving direction of the movable member. In this case, the arc generated between the second fixed contact and the second movable contact can be suppressed from going around the movable contact piece by the second blocking wall.

The electromagnetic relay 1 further includes a first blocking wall 31, a second blocking wall 32, a first magnet 33, a second magnet 34, and a yoke 35, as shown in FIGS.

The first blocking wall 31 is made of an insulating material such as resin. The first blocking wall 31 is fixed to the movable member 9 . In the present embodiment, the first blocking wall 31 is made of resin and formed integrally with the movable member 9 . The first blocking wall 31 is arranged above the first movable contact 8a. The first blocking wall 31 is arranged on the side of the movable contact piece 8 opposite to the side on which the first movable contact 8a is arranged (here, the upper surface side). The first blocking wall 31 is vertically separated from the movable contact piece 8 .

The first blocking wall 31 extends in the longitudinal direction of the movable contact piece 8 from the left side surface of the movable member 9 toward the first movable contact 8 a and in the moving direction of the movable member 9 . The first blocking wall 31 extends leftward from the left side surface of the movable member 9 .

The first magnet 33 and the second magnet 34 are permanent magnets. The first magnet 33 and the second magnet 34 are arranged so that magnetic flux flows in the horizontal direction between the first fixed contact 6a and the first movable contact 8a and between the second fixed contact 7a and the second movable contact 8b. It is The first magnet 33 and the second magnet 34 are arranged so that different poles face each other in the horizontal direction. The first magnet 33 and the second magnet 34 are attached to the outer peripheral surface of the case 20 . The yoke 35 is arranged to cover the first magnet 33 and the second magnet 34 from the outside.

Next, the operation of the electromagnetic relay 1 will be explained. In the open state where no voltage is applied to the coil 4a, the elastic force of the hinge spring 4f and the return spring 4g presses the movable member 9 in the opening direction. Therefore, the first movable contact 8a is separated from the first fixed contact 6a, and the second movable contact 8b is separated from the second fixed contact 7a.

When a voltage is applied to the coil 4a to excite the driving device 4, the movable iron piece 4e is attracted to the fixed iron core 4c and rotates, and the movable member 9 is pressed in the contact direction by the movable iron piece 4e. As a result, the movable member 9 moves in the contact direction against the elastic force of the hinge spring 4f and the return spring 4g. As the movable member 9 moves in the contact direction, the contact spring 10 moves in the contact direction. As a result, the movable contact piece 8 moves in the contact direction, the first movable contact 8a contacts the first fixed contact 6a, and the second movable contact 8b contacts the second fixed contact 7a. When the voltage application to the coil 4a is stopped, the movable member 9 moves in the opening direction due to the elastic forces of the hinge spring 4f and the return spring 4g.

In this electromagnetic relay 1, the first shielding wall 31 is arranged on the side of the movable contact piece 8 opposite to the side on which the first movable contact 8a is arranged. As a result, the arc generated between the first fixed contact 6a and the first movable contact 8a can be prevented from going around the movable contact piece 8 by the first shielding wall 31 .

Specifically, in FIG. 2, as schematically shown by a chain double-dashed line, for example, current flows from the first movable contact 8a toward the first fixed contact 6a, and the magnetic flux flows rightward between the contacts. When flowing, a forward Lorentz force acts on the arc generated between the first fixed contact 6a and the first movable contact 8a. When the arc is extended by this Lorentz force, the arc hits the front surface of the first blocking wall 31 . As a result, the first shielding wall 31 can prevent the arc from circulating around the movable contact piece 8 .

In addition, in the present embodiment, the first blocking wall 31 is positioned right above the first movable contact 8a when viewed in the left-right direction. As a result, even when the direction in which the current flows changes and the direction in which the arc extends changes, the arc can be blocked by the first blocking wall 31 in a well-balanced manner.

Also, the first blocking wall 31 is fixed to the movable member 9 that holds the movable contact piece 8 . As a result, the positional relationship between the movable contact piece 8 and the first blocking wall 31 is stabilized, so that the first blocking wall 31 provides a stable blocking effect. The arc generated between the second fixed contact 7a and the second movable contact 8b can be stably interrupted by the second shielding wall 32. FIG.

Also, the first blocking wall 131 may further include an inclined portion 131b paired with the inclined portion 131a.

The first blocking wall 231 shown in FIG. 7 has a T shape when viewed from the left-right direction. The first blocking wall 231 includes an extension 231a against which the arc hits. The extending portion 231a extends in a direction perpendicular to the vertical direction. The first blocking wall 231 may be L-shaped when viewed in the horizontal direction.
