Abstract

In an electromagnetic relay, a connection terminal includes a first terminal section and a second terminal section. The first terminal section is accommodated in a base and is electrically connected to a coil. The second terminal section protrudes outside the base through a through hole and is electrically connected to an external connection body. The cover includes a second wall section provided to leave a space from a first wall section that has a through hole, and the second terminal section lies in the space. The space in which the second terminal section lies is sealed with a sealant.

Claims (41)

1. An electromagnetic relay, comprising:

a contact point including a fixed contact and a movable contact;

a driver including a coil and is configured to bring the movable contact into contact with the fixed contact and to separate the movable contact from the fixed contact;

a base having an opening and including a first wall section surrounding an accommodation space in which the contact point and the driver are accommodated;

a cover covering the opening of the base; and

at least one connection terminal configured to electrically connect the coil to an external connection body, wherein

the first wall section of the base has a through hole communicating with an interior and an exterior of the accommodation space,

the at least one connection terminal includes:

a first terminal section accommodated in the base and electrically connected to the coil; and

a second terminal section protruding outside the base through the through hole and electrically connected to the external connection body,

the cover includes a second wall section disposed to leave a space from the first wall section having the through hole, and the second terminal section lies in the space, and

the space in which the second terminal section lies is sealed with a sealant.

2. The electromagnetic relay according to claim 1 , wherein

the second terminal section includes:

a first joint section extended in a protrusion direction in which the second terminal section protrudes from the first terminal section; and

a second joint section extended from the first joint section in a direction orthogonal to the protrusion direction.

3. The electromagnetic relay according to claim 2 , wherein

the cover includes an opening surface orthogonal to a direction in which the second joint section is extended in the space.

4. The electromagnetic relay according to claim 1 , wherein

the at least one connection terminal includes a plurality of connection terminals,

the plurality of connection terminals protrude from the first wall section, and

the cover includes an opening surface that has a normal direction along a direction orthogonal to a direction in which the plurality of connection terminals are aligned and to a direction in which the second terminal section protrudes from the first terminal section in the space.

5. The electromagnetic relay according to claim 2 , wherein

the at least one connection terminal includes a plurality of connection terminals,

the plurality of connection terminals protrude from the first wall section, and

the cover includes an opening surface that has a normal direction along a direction orthogonal to a direction in which the plurality of connection terminals are aligned and to a direction in which the second terminal section protrudes from the first terminal section in the space.

6. A relay device, comprising:

the electromagnetic relay according to claim 1 ; and

an external connection body electrically connected to the second terminal section of the at least one connection terminal.

7. A relay device, comprising:

the electromagnetic relay according to claim 2 ; and

an external connection body electrically connected to the second terminal section of the at least one connection terminal.

8. A relay device, comprising:

the electromagnetic relay according to claim 3 ; and

an external connection body electrically connected to the second terminal section of the at least one connection terminal.

9. A relay device, comprising:

the electromagnetic relay according to claim 4 ; and

an external connection body electrically connected to the second terminal section of the at least one connection terminal.

10. A relay device, comprising:

the electromagnetic relay according to claim 5 ; and

an external connection body electrically connected to the second terminal section of the at least one connection terminal.
