Connector
In the present invention, a cover closes an opening in a housing holding a plurality of terminals. Each of the terminals has a connection part connecting to a mate terminal. The cover has a first surface, a second surface located at a rear side of the first surface including an exposed surface exposed to the inner side of the housing through the opening, a first reinforcement rib projecting from the first surface, and a second reinforcement rib projecting from the second surface. The direction in which the plurality of connection parts are arranged is defined as a first direction. The direction that intersects the first direction and that is oriented from the basal end toward the distal end of the connection parts is defined as a second direction. The first reinforcement rib extends along the first direction. The second reinforcement rib extends along the second direction between adjacent connection parts.
1. A connector comprising:
a connector housing including an opening;
a cover closing the opening; and
terminals held by the connector housing, wherein
each of the terminals includes a connection part configured to be electrically connected to one of a plurality of mate terminals, the mate terminals differing from one another,
the connection parts are arranged in a line in the connector housing,
the cover includes a first surface exposed outside the connector housing and a second surface located at a rear side of the first surface,
the second surface includes an exposed surface exposed through the opening to an inner side of the connector housing,
the cover further includes at least one first reinforcement rib projecting from the first surface and at least one second reinforcement rib projecting from the second surface,
when a first direction refers to a direction in which the connection parts are arranged, a second direction refers to a direction intersecting the first direction and extending from a basal end to a distal end of the connection parts, and a third direction refers to a direction orthogonal to the first direction and the second direction, the first reinforcement rib extends in the first direction, and the second reinforcement rib extends in the second direction between adjacent ones of the connection parts as viewed in the third direction.
2. The connector according to claim 1 , wherein
the cover includes a sealing portion projecting from the second surface to surround the exposed surface as viewed in the third direction, the sealing portion is fitted into the opening, and
at least one of the second reinforcement rib is greater than the sealing portion in a length of projection from the second surface.
3. The connector according to claim 1 , wherein
the cover includes a resin molding component, and
as viewed in any of the second direction and the third direction, the second reinforcement rib is disposed between each two of the connection parts located adjacent to each other in the first direction.
4. The connector according to claim 1 , wherein
the second surface extends wider than the exposed surface in opposite directions along the first direction,
the connector housing includes two first guides extending in the third direction from two ends of the connector housing located at opposite sides in the first direction,
the cover includes two second guides projecting from two parts of the second surface located outward from the exposed surface in the first direction, and
the two second guides are fitted to the two first guides using a recess and a projection to restrict misalignment of the connector housing with the cover in the first direction and the second direction.
5. The connector according to claim 4 , wherein
the cover includes two first reinforcement parts and/or two second reinforcement parts,
the two first reinforcement parts extend on the second surface from the two second guides to a first end of the cover in the second direction, and
the two second reinforcement parts extend on the second surface from the two second guides to a second end of the cover in the second direction.
6. The connector according to claim 1 , wherein the cover includes a peripheral wall projecting from the first surface and extending along a peripheral edge of the first surface.
7. The connector according to claim 6 , wherein the peripheral wall annularly extends along the peripheral edge of the first surface.
8. The connector according to claim 1 , wherein
the at least one second reinforcement rib includes second reinforcement ribs, and
the cover includes at least one joint rib that joins ones of the second reinforcement ribs that are located adjacent to each other in the first direction.
9. The connector according to claim 1 , wherein the cover includes two of the first reinforcement rib.
10. The connector according to claim 1 , wherein
the cover includes two end surfaces located in the second direction,
at least one of the two end surfaces includes an outward surface extending in the first direction, and
the cover includes
a sealing portion projecting from the second surface to surround the exposed surface as viewed in the third direction, the sealing portion is fitted into the opening,
an annular sealant sealing a gap between the connector housing and an outer surface of the sealing portion that faces the connector housing, and
a protrusion protruding from at least one of the outward surface in the second direction or a direction opposite to the second direction.
