Abstract

A connector ( 10 ) includes a housing ( 30 ) with a wire draw-out portion ( 34 ) from which wires (W) are drawn out. Rubber plugs ( 27 ) are accommodated in rubber plug accommodating portions ( 41 ) in the housing ( 30 ) and seal between the wires (W) and inner peripheral surfaces of the rubber plug accommodating portions ( 41 ). A back retainer ( 50 ) is mounted through a wire draw-out opening ( 34 A) in the wire draw-out portion ( 34 ) and retains the rubber plugs ( 27 ). The back retainer ( 50 ) includes a retainer main body ( 52 ) for preventing backward movements of the rubber plugs ( 27 ) while allowing the insertion of the wires W therethrough. A position where the wires (W) are drawn out backward in the retainer main body ( 52 ) is closer to a back part of the wire draw-out portion ( 34 ) than the wire draw-out opening ( 34 A).

First claim

What is claimed is:

1. A connector, comprising:
a housing with a wire draw-out opening from which wires are drawn out;
a rubber plug accommodated in the housing and sealing between the wires and an inner peripheral surface of the housing; and
a retainer mounted into the housing through the wire draw-out opening and retaining the rubber plug, the retainer including a retainer main body for preventing a movement of the rubber plug in a direction to come out while allowing the insertion of the wires therethrough, and a position where the wires are drawn out in the retainer main body is arranged closer to a back part of the housing than the wire draw-out opening, wherein the retainer includes a guide extending from the retainer main body to the wire draw-out opening along the inner peripheral surface of the housing.

2. The connector of claim 1 , wherein the rubber plug has opposite front and rear surfaces spaced apart along an insertion direction of the wires through the rubber plug to define a rubber plug, the main body of the retainer having opposite front and rear surfaces defining a thickness that is less than the rubber plug thickness.

3. The connector of claim 1 , wherein:
cavities for individually accommodating the wires are provided side by side in a row while being partitioned by partition walls in the housing; and
a space where the wires drawn out from the retainer main body are arranged is continuous in an arrangement direction of the wires by cutting the partition walls between the cavities from the retainer main body to the wire draw-out opening.

4. The connector of claim 1 , further comprising a metal shield bracket and a shield member for covering the wires is connected to the shield bracket, wherein:
an area of the housing from the retainer main body to the wire draw-out opening is covered by the shield bracket.

5. The connector of claim 1 , wherein the housing has a plurality of cavities for accommodating terminals, the wires being connected respectively to the terminals, the retainer main body having a plurality of wire insertion holes aligned respectively with the cavities and dimensioned respectively for accommodating the wires drawn out from the cavities, the guide of the retainer defining a single arrangement space communicating with all of the wire insertion holes of the retainer and all of the cavities of the housing.

6. The connector of claim 5 , wherein the cavities are arranged in a lateral direction and the wires are bent in the lateral direction within the arrangement space of the retainer.

7. The connector of claim 6 , wherein the connector further has a height direction transverse to the lateral direction and transverse to an insertion direction of the terminals into the cavities, the arrangement space of the retainer having a dimension in the height direction that exceeds a dimension of the respective cavities in the height direction.
