Abstract
A seal part includes an elastic body that is in close contact with outer peripheral surfaces of a plurality of wires and an inner peripheral surface of a wire accommodation portion, and a rigid body that has an outer peripheral surface disposed to face the inner peripheral surface of the wire accommodation portion. The rigid body has a plurality of wire through holes allowing wires to coaxially pass through respectively. The elastic body includes first seal portions that respectively correspond to the wire through holes, and that are in close contact with the outer peripheral surfaces of the wires passing through the wire through holes, and a second seal portion that is in close contact with the inner peripheral surface of the wire accommodation portion in the wire accommodation portion.
Claims12
A sealing structure for a connector, comprising:
- a housing accommodating a plurality of wired terminals and allowing wires of the wired terminals respectively to be drawn out;
- a seal part sealing gaps between outer peripheral surfaces of the wires and an inner peripheral surface of the housing;
- and
- a holder part holding the seal part, wherein
- the housing includes a wire accommodation portion accommodating the wires and allowing the wires to be drawn out of an opening,
- the seal part includes:
- an elastic body that is in close contact with outer peripheral surfaces of a plurality of wires arranged in parallel to each other, per each of the wires, and that is in close contact with an inner peripheral surface of the wire accommodation portion;
- and
- a rigid body that is higher in rigidity than the elastic body, the rigid body having an outer peripheral surface allowed to be disposed, in the wire accommodation portion, to face the inner peripheral surface of the wire accommodation portion at a gap,
- the rigid body has
- a plurality of wire through holes allowing the wires to coaxially pass through respectively, and
- target-fitting portions disposed to face the opening in the wire accommodation portion, the target-fitting portions allowing fitting portions of the holder part accommodated in the wire accommodation portion at a position closer to the opening than the rigid body to fit in an axis direction of the wire through holes,
- the target-fitting portions are each formed into a recessed shape recessed in the axis direction of the wire through holes in a case where the fitting portions are each formed into a projecting shape, whereas are each formed into a projecting shape projecting in the axis direction of the wire through holes in a case where the fitting portions are each formed into a recessed shape, and
- the elastic body includes
- first seal portions respectively corresponding to the wire through holes, the first seal portions each having a cylindrical shape with respect to inner peripheral surfaces of the wire through holes, the first seal portions being in close contact with the outer peripheral surfaces of the wires passing through the wire through holes, and
- a second seal portion having a cylindrical shape with respect to the outer peripheral surface of the rigid body, the second seal portion being in close contact, in the wire accommodation portion, with the inner peripheral surface of the wire accommodation portion.
