Terminal block
A terminal block including: a connector that has a tubular shape; and a seating that is formed on an outer periphery of the connector, and is to be fixed to the housing so as to close an opening of the housing, wherein: the seating includes: a first wall that extends in a direction that intersects an axial direction of the connector; a second wall that faces the first wall in the axial direction of the connector; a rib that is provided between the first wall and the second wall so as to connect the first wall and the second wall with each other; and a space that is partitioned by the rib between the first wall and the second wall, and the space is open in a direction that intersects the axial direction of the connector.
1. A terminal block that is to be provided on a housing of a device that is to be mounted on a vehicle, the terminal block comprising:
a connector that has a tubular shape; and
a seating that is formed on an outer periphery of the connector, and is to be fixed to the housing so as to close an opening of the housing, wherein:
the seating includes:
a first wall that extends in a direction that intersects an axial direction of the connector;
a second wall that faces the first wall in the axial direction of the connector;
a rib that is provided between the first wall and the second wall so as to connect the first wall and the second wall with each other; and
a space that is partitioned by the rib between the first wall and the second wall, and
the space is open in a direction that intersects the axial direction of the connector.
2. The terminal block according to claim 1 ,
wherein the rib includes a first rib and a second rib that intersect each other.
3. The terminal block according to claim 1 , wherein:
a back surface of the seating is provided with a seal that has a ring shape, and
in a state where the terminal block is attached to the housing, the seal is compressed by being sandwiched between the housing and the second wall at a position where the seal surrounds the opening.
4. The terminal block according to claim 3 ,
the second wall is provided with a housing groove in which the seal is to be disposed.
5. The terminal block according to claim 1 , wherein:
the seating is provided with a plurality of fastening-target portions that are to be fastened and fixed to the housing, and
the first wall and the second wall are formed so as to connect the plurality of fastening-target portions with each other.
6. The terminal block according to claim 1 , wherein:
the seating is provided with a standing rib that stands thereon in the axial direction of the connector, and a recess that is partitioned by the standing rib and is open in the axial direction of the connector, and
the recess is provided with a drainage hole that brings an inside and an outside of the recess into communication with each other.
7. The terminal block according to claim 6 , wherein:
the first wall and the second wall are provided on sides of the terminal block in a longitudinal direction thereof when the terminal block is seen in the axial direction of the connector, and
the standing rib and the recess are provided on sides of the terminal block in a lateral direction thereof when the terminal block is seen in the axial direction of the connector.
