Connector
A connector according to the present disclosure is provided with a plurality of terminals, a plurality of wires, a housing including a tubular portion having an opening, and a cover for covering the opening by being inserted into the tubular portion. The cover includes a cover body having a vent, and a breathable film for covering the vent. The cover body includes an inner wall surrounding an outer periphery of the breathable film and an outer wall located on an outer peripheral side of the inner wall and surrounding an outer peripheral edge of the cover body. The inner wall includes an inner discharge port allowing communication between inside and outside of the inner wall in a direction orthogonal to a Z-axis direction. The outer wall includes an outer discharge port allowing communication between inside and outside of the outer wall in a direction orthogonal to the Z-axis direction.

a cover for covering the opening by being inserted into the tubular portion,
the end part of each terminal being provided with a bolt hole, the bolt hole penetrating in an axial direction of the tubular portion, a bolt being inserted into the bolt hole,
the cover including:
a cover body made of resin, the cover body having a vent penetrating in the axial direction, the cover body covering the opening; and
a breathable film for covering the vent from a side opposite to the plurality of terminals in the axial direction, the breathable film allowing passage of gases and inhibiting passage of liquids,
the cover body including an inner wall surrounding an outer periphery of the breathable film and an outer wall located on an outer peripheral side of the inner wall and including an outer peripheral edge of the cover body,
the inner wall including an inner discharge port allowing communication between inside and outside of the inner wall in a direction orthogonal to the axial direction,
the outer wall including an outer discharge port allowing communication between inside and outside of the outer wall in a direction orthogonal to the axial direction, and
the inner discharge port facing an inner peripheral surface of the outer wall, the outer discharge port facing an outer peripheral surface of the inner wall.
2 . The connector of claim 1 , wherein:
if a virtual axis extending in a communicating direction of the inner discharge port is a first virtual axis and a virtual axis extending in a communicating direction of the outer discharge port is a second virtual axis,
the entire inner discharge port is provided closer to a side where the outer discharge port is located than an intersection of the first and second virtual axes in an axial direction of the second virtual axis.
3 . The connector of claim 2 , wherein:
the inner wall has a first end edge and a second end edge forming the inner discharge port,
the first end edge is located closer to the outer discharge port than the second end edge,
the inner wall is provided with an extending portion extending to include the first end edge, and
the extending portion extends obliquely to the second virtual axis to approach the outer discharge port in the axial direction of the second virtual axis toward the first end edge.
4 . The connector of claim 1 , comprising a shield shell made of metal, the shield shell covering an outer periphery of the tubular portion, wherein:
the shield shell covers the outer discharge port from an outer peripheral side of the outer wall.
5 . The connector of claim 1 , wherein the cover body includes a separation wall located between two mutually adjacent ones of the terminals.
6 . The connector of claim 5 , wherein:
the cover body includes:
a facing wall located on a side opposite to the separation wall across one terminal fitting and facing the separation wall; and
a coupling wall located on a side opposite to the holding portion across the one terminal and coupling the separation wall and the facing wall, and
the coupling wall is configured to restrict insertion of the cover into the tubular portion by contacting the terminal if the cover is inserted into the tubular portion while being inverted about a center axis of the tubular portion with respect to a proper posture.
7 . The connector of claim 6 , wherein:
each terminal includes a first extending portion extending from the holding portion toward inside of the tubular portion, a second extending portion extending in the axial direction from the first extending portion and a third extending portion extending from the second extending portion toward a side opposite to the first extending portion in an extending direction of the first extending portion and provided with the bolt hole, and
the cover body includes a second coupling wall located between the first coupling wall and the second extending portion and coupling the separation wall and the facing wall when the coupling wall is a first coupling wall.
8 . The connector of claim 1 , wherein the housing includes a rib coupling an outer surface of a part of the holding portion located between two mutually adjacent ones of the terminals and an outer surface of the tubular portion.
9 . The connector of claim 8 , wherein the rib includes a recess.
10 . The connector of claim 1 , comprising an interlock connector provided inside the tubular portion, the interlock connector electrically detecting whether or not the housing is connected to a connection target at a proper position, wherein:
the interlock connector is provided in parallel to the plurality of terminals in a parallel direction of the plurality of terminals.
11 . The connector of claim 10 , wherein:
the cover body includes an accommodating portion for accommodating one end of the interlock connector, and
the accommodating portion is configured to restrict insertion of the cover into the tubular portion by contacting the terminal if the cover is inserted into the tubular portion while being inverted about a center axis of the tubular portion with respect to a proper posture.
12 . The connector of claim 10 , wherein the tubular portion includes a partition wall partitioning inside of the tubular portion between the plurality of terminals and the interlock connector.
