Abstract

The movable body includes a pivot and a contact portion. The pivot is rotatably supported. The contact portion is disposed at a position contactable with a contact piece. The movable body rotates around the pivot and presses the contact piece via the contact portion to move the second contact close to the first contact. The actuator presses the movable body to rotate the movable body around the pivot. The contact piece has a curved portion located between the second contact and the support. The pivot is located on a side where the support is disposed with respect to the curved portion. The actuator includes a pressing member which presses the movable body. The pressing member moves in an axial direction of the pressing member to press the movable body.

First claim

The invention claimed is:

1. A relay comprising:
a first contact;
a second contact disposed at a position facing the first contact;
a contact piece to which the second contact is attached;
a support configured to support the contact piece;
a movable body that includes a pivot rotatably supported and a contact portion disposed at a position contactable with the contact piece, the movable body configured to rotate around the pivot and press the contact piece via the contact portion to move the second contact close to the first contact; and
an actuator configured to press the movable body to rotate the movable body around the pivot, wherein
the contact piece includes a curved portion located between the second contact and the support,
the pivot is located on a side where the support is disposed with respect to the curved portion,
the actuator includes a pressing member configured to press the movable body, and
the pressing member moves in a direction of an axis of the pressing member to press the movable body.

2. The relay according to claim 1 , wherein a pressing position at which the pressing member presses the movable body is located between the pivot and the contact portion.

3. The relay according to claim 2 , wherein the pressing position is located on a side where the second contact is disposed with respect to the curved portion.

4. The relay according to claim 2 , wherein the pressing position is located on a side where the curved portion is disposed with respect to the second contact.

5. The relay according to claim 1 , wherein the movable body has a bent shape.

6. The relay according to claim 1 , wherein the movable body includes
a first movable portion that includes the pivot, and extends in a lengthwise direction of the contact piece, and
a second movable portion that includes the contact portion, and extends from the first movable portion toward the contact piece.

7. The relay according to claim 6 , wherein the first movable portion and the second movable portion are separate portions.

8. The relay according to claim 6 , wherein the first movable portion and the second movable portion are integrated into one piece.

9. The relay according to claim 8 , wherein a leading end portion of the contact piece has a shape bent toward the contact portion.

10. The relay according to claim 1 , wherein a leading end of the pressing member has a curved shape.

11. The relay according to claim 1 , wherein
the pressing member is configured to move in the direction of the axis of the pressing member, and rotate around the axis, and
a leading end of the pressing member has a spherical shape.

12. The relay according to claim 1 , wherein
the pressing member is configured to move to an off-position where the first contact and the second contact are not in contact with each other, and an on-position where the first contact and the second contact are in contact with each other, and
the actuator further includes a retaining member that latches the pressing member to retain the pressing member at the on-position.
