Abstract

There is provided a shield connector that allows reliable prevention of a rubber plug from being detached from a housing. A shield connector has a terminal fitting connected to an end of an electrical wire, a housing accommodating the terminal fitting, a shield shell covering the housing, and a rubber plug attached to an outer circumference of the electrical wire for waterproofing of the inner space of the housing. The shield shell includes an electrical-wire insertion hole through which the electrical wire is passed. The rubber plug includes a packing and a resin member made in one piece with the packing. The resin member includes a cylindrical body and a flange portion protruding from an outer circumferential surface of the cylindrical body. An end of the cylindrical body is in the electrical-wire insertion hole, and the flange portion is sandwiched by the housing and the electrical-wire insertion hole.

Claims

1. A shield connector comprising:

(a) a terminal fitting connected to an end of an electrical wire;

(b) a housing accommodating the terminal fitting;

(c) a shield shell covering the housing, the shield shell having an electrical-wire insertion hole through which the electrical wire is passed; and

(d) a rubber plug attached on an outer circumference of the electrical wire for waterproofing of the housing, the rubber plug including a packing and a resin member made in one piece with the packing, the resin member including a cylindrical body and a flange portion protruding in a flange-like manner from an outer circumferential surface of the cylindrical body, an end of the cylindrical body being positioned in the electrical-wire insertion hole, wherein the end is defined with reference to an axis of the cylindrical body, and the flange portion abutting on an outer edge of the electrical-wire-insertion hole,

wherein the flange portion is sandwiched by the housing and the outer edge of the electrical-wire insertion hole.

2. The shield connector as set forth in claim 1, wherein the resin member further includes a secondary cylindrical body extending from an other end of the cylindrical body and having inner and outer diameters smaller than those of the cylindrical body, the other end being defined with reference to the axis of the cylindrical body, the packing includes:

(a) an inner cylindrical portion arranged in the cylindrical body to be in contact with an inner circumference of the cylindrical body;

(b) an inner circumferential lip protruding from the inner cylindrical portion and being firmly attached to an outer circumferential surface of the electrical wire;

(c) an outer cylindrical portion arranged on an outer circumference of the secondary cylindrical body; and

(d) an outer circumferential lip protruding from the outer cylindrical portion and being firmly attached to an inner surface of the housing, and a gap is provided between the secondary cylindrical body and the inner circumferential lip.
