Abstract

A waterproof connector ( 1 ) includes an accommodation recess ( 31 ) formed in a wire draw-out surface ( 26 ) of a housing ( 10 ) and configured to accommodate a ventilation film ( 63 ). A wire cover ( 50 ) is mounted on the housing ( 10 ) to cover the wire draw-out surface ( 26 ) and the accommodation recess ( 31 ). A wire bending space ( 54 ) inside the wire cover ( 50 ) is configured to bend wires ( 15 ) drawn out from the wire draw-out surface ( 26 ). A partition ( 56 ) is formed in the wire cover ( 50 ) and partitions between the accommodation recess ( 31 ) and the wire bending space ( 54 ) by contacting the wire draw-out surface ( 26 ) to cover an opening of the accommodation recess ( 31 ). Drainage portions ( 37, 38, 39, 40 ) are formed in a contact area between the wire draw-out surface ( 26 ) and the partition ( 56 ) and has a convexo-concave or stepped cross-sectional shape.

Claims (32)

1. A waterproof connector, comprising:

a housing formed with a terminal accommodation chamber inside, a wire draw-out surface being defined on a part of an outer surface of the housing;

a terminal fitting connected to an end part of a wire, the terminal fitting being inserted into the terminal accommodation chamber with the wire drawn to outside of the housing from the wire draw-out surface;

an upwardly open accommodation recess formed in the wire draw-out surface and configured to accommodate a ventilation film;

a drainage path formed in the housing and being open in a lower surface of the accommodation recess, a blocking portion formed at an intermediate position of a drainage route in the drainage path and forming the drainage path into a bent route;

a wire cover configured to cover the wire draw-out surface and the accommodation recess;

a wire bending space formed inside the wire cover and configured to bend the wire drawn out from the wire draw-out surface;

a partitioning portion formed in the wire cover and configured to partition between the accommodation recess and the wire bending space by being brought into contact with the wire draw-out surface to cover an opening of the accommodation recess; and

a drainage portion formed in a contact area between the wire draw-out surface and the partitioning portion and having a convexo-concave or stepped cross-sectional shape.

2. A waterproof connector, comprising:

a housing formed with a terminal accommodation chamber inside, a wire draw-out surface being defined on a part of an outer surface of the housing;

a terminal fitting connected to an end part of a wire, the terminal fitting being inserted into the terminal accommodation chamber with the wire drawn to outside of the housing from the wire draw-out surface;

an accommodation recess formed in the wire draw-out surface and configured to accommodate a ventilation film;

a wire cover configured to cover the wire draw-out surface and the accommodation recess;

a wire bending space formed inside the wire cover and configured to bend the wire drawn out from the wire draw-out surface;

a partitioning portion formed in the wire cover and configured to partition between the accommodation recess and the wire bending space by being brought into contact with the wire draw-out surface to cover an opening of the accommodation recess; and

a drainage portion formed in a contact area between the wire draw-out surface and the partitioning portion and having a convexo-concave or stepped cross-sectional shape;

a one-piece rubber plug mounted in the housing with the wire passed therethrough in an airtight manner;

a peripheral wall formed in the housing and configured to surround the one-piece rubber plug in an airtight manner; and

a holder including a tubular ventilation portion penetrating through the one-piece rubber plug and configured to accommodate the ventilation film;

wherein:

the accommodation recess is formed from an inner side to an outer side of the peripheral wall; and

an upstream end of the drainage path is open in an area of the accommodation recess outside the peripheral wall.

3. A waterproof connector comprising:

a housing formed with a terminal accommodation chamber inside, a wire draw-out surface being defined on a part of an outer surface of the housing;

a terminal fitting connected to an end part of a wire, the terminal fitting being inserted into the terminal accommodation chamber with the wire drawn to outside of the housing from the wire draw-out surface;

an accommodation recess formed in the wire draw-out surface and configured to accommodate a ventilation film;

a wire cover configured to cover the wire draw-out surface and the accommodation recess, a wire bending space formed inside the wire cover and configured to bend the wire drawn out from the wire draw-out surface, a restricting portion formed in the wire cover and configured to restrict a displacement of the ventilation film in a direction separating from the accommodation recess,

a partitioning portion formed in the wire cover and configured to partition between the accommodation recess and the wire bending space by being brought into contact with the wire draw-out surface to cover an opening of the accommodation recess; and

a drainage portion formed in a contact area between the wire draw-out surface and the partitioning portion and having a convexo-concave or stepped cross-sectional shape.

4. The waterproof connector of claim 3 , wherein the opening of the accommodation recess is facing upward, and a drainage path open in a lower surface of the accommodation recess is formed in the housing.

5. The waterproof connector of claim 4 , comprising a blocking portion formed at an intermediate position of a drainage route in the drainage path and forming the drainage path into a bent route.
