Connector
A connector according to one aspect of the present disclosure is provided with a housing including an inserting portion and an annular first sealing member to be mounted on an outer peripheral surface of the inserting portion. The first sealing member includes a sealing body and an engaging portion having a first engaging projection and a second engaging projection. The first and second engaging projections are provided at positions overlapping each other in a Z-axis direction. The first engaging projection projects more toward one side in a circumferential direction than the second engaging projection. The second engaging projection projects more toward the other side in the circumferential direction than the first engaging projection. An accommodation groove provided in the outer peripheral surface of the inserting portion includes a groove body and an engaged portion having a first engaging groove and a second engaging groove.
1 . A connector to be inserted into an insertion hole provided in a connection target, comprising:
a plurality of terminals parallel to each other,
a plurality of wires to be respectively connected to the plurality of terminals;
a housing made of resin and including an inserting portion to be inserted into the insertion hole, the housing holding the plurality of terminals and the plurality of wires; and
an annular sealing member for stopping water between the inserting portion and the insertion hole by being mounted on an outer peripheral surface of the inserting portion,
when a circumferential direction and an axial direction of the sealing member are respectively merely referred to as a circumferential direction and an axial direction,
the sealing member including an annular sealing body and an engaging portion having a first engaging projection and a second engaging projection projecting from the sealing body toward sides opposite to each other in the axial direction,
the first and second engaging projections being provided at positions overlapping each other in the axial direction,
the first engaging projection projecting more toward one side in the circumferential direction than the second engaging projection,
the second engaging projection projecting more toward the other side in the circumferential direction than the first engaging projection,
an accommodation groove for accommodating the sealing member being provided in the outer peripheral surface of the inserting portion,
the accommodation groove including a groove body for accommodating the sealing body and an engaged portion having a first engaging groove and a second engaging groove extending toward the sides opposite to each other in the axial direction and to be respectively engaged with the first and second engaging projections,
the first engaging groove and the second engaging groove being provided at positions overlapping each other in the axial direction,
the first engaging groove extending more toward the one side in the circumferential direction than the second engaging groove, and
the second engaging groove extending more toward the other side in the circumferential direction than the first engaging groove.
2 . The connector of claim 1 , wherein:
the housing includes a tubular portion having the inserting portion and a holding portion projecting from the tubular portion toward an outer peripheral side of the tubular portion, the holding portion holding the plurality of terminals and the plurality of wires, and
when a direction orthogonal to both the axial direction and a projecting direction of the holding portion is an orthogonal direction,
the engaging portion is provided at one end in the orthogonal direction of the sealing body, and
the engaged portion is provided at one end in the orthogonal direction of the groove body.
3 . The connector of claim 1 , wherein:
a central part in the circumferential direction of the first engaging projection is provided at a position overlapping the second engaging projection in the axial direction, and
a central part in the circumferential direction of the second engaging projection is provided at a position overlapping the first engaging projection in the axial direction.
4 . The connector of claim 1 , wherein the first and second engaging projections have the same shape.
5 . The connector of claim 1 , wherein:
the sealing member includes a plurality of engaging portions provided apart from each other in the circumferential direction, and
the accommodation groove includes a plurality of engaged portions provided apart from each other in the circumferential direction.
6 . The connector of claim 5 , wherein:
the sealing member includes two engaging portions located on sides opposite to each other across a center axis of the sealing member and is shaped to be point symmetric with the center axis as an axis of symmetry, and
the accommodation groove includes two engaged portions located on sides opposite to each other across the center axis.
7 . The connector of claim 1 , comprising a shield shell made of metal for covering an outer periphery of the housing, wherein:
the sealing member is located outside the shield shell.
8 . The connector of claim 1 , wherein the housing includes a tubular portion having a first end part and a second end part, the axial direction being a direction from the first end part toward the second end part,
the one side in the circumferential direction is a counterclockwise direction when the second end part is viewed along the axial direction, and
the other side in the circumferential direction is a clockwise direction when the second end part is viewed along the axial direction.
