Abstract

A seal member for an electrical connector comprises a base portion, a wire seal portion disposed in the base portion, a housing seal portion disposed on an outer end portion of a radial outside of the base portion, and a shell seal portion integrally formed with the base portion, the wire seal portion, and the housing seal portion. The wire seal portion is configured to contact an outer peripheral portion of a wire led out from a housing of the electrical connector. The housing seal portion is configured to be pressed against the housing. The shell seal portion is configured to be pressed against at least a bottom portion of a shell enclosing the housing.

First claim

What is claimed is:

1 . A seal member for an electrical connector, comprising:
a base portion;
wire seal portion disposed in the base portion and configured to contact an outer peripheral portion of a wire led out from a housing of the electrical connector;
a housing seal portion disposed on an outer end portion of a radial outside of the base portion and configured to be pressed against the housing; and
a shell seal portion integrally formed with the base portion, the wire seal portion, and the housing seal portion and configured to be pressed against at least a bottom portion of a shell enclosing the housing.

2 . The seal member of claim 1 , further comprising a peripheral wall protruding from the base portion.

3 . The seal member of claim 2 , wherein a region of the bottom portion of the shell is inserted into the peripheral wall.

4 . The seal member of claim 3 , wherein the shell seal portion is disposed on an inner peripheral portion of the peripheral wall.

5 . The seal member of claim 4 , wherein the peripheral wall protrudes radially outside the outer end portion of the base portion.

6 . The seal member of claim 1 , wherein the base portion has a seal hole extending through the base portion from a front portion of the base portion to a rear portion of the base portion.

7 . The seal member of claim 6 , wherein the wire seal portion is disposed on an inner peripheral portion of the seal hole and the wire extends through the seal hole.

8 . The seal member of claim 6 , wherein the shell seal portion, the base portion, the wire seal portion, and the housing seal portion are integrally formed from an elastic material.

9 . The seal member of claim 8 , wherein the front portion and/or the rear portion have a plurality of depressions configured to facilitate elastic deformation of the base portion.

10 . An electrical connector, comprising:
a housing configured to be mated with a mating housing; a shell made of a metal material and enclosing the housing; and a seal member configured to be penetrated by a wire led out from the housing, the seal member pressed between a bottom portion of the shell and the housing and including:
a base portion;

wire seal portion disposed in the base portion and configured to contact an outer peripheral portion of the wire;
a housing seal portion disposed on an outer end portion of a radial outside of the base portion and configured to be pressed against the housing; and
a shell seal portion integrally formed with the base portion, the wire seal portion, and the housing seal portion and configured to be pressed against the bottom portion of the shell.

11 . The electrical connector of claim 10 , wherein the wire is covered with a braided wire and an end portion of the braided wire is connected to an outer peripheral portion of the shell.

12 . The electrical connector of claim 10 , wherein the housing retains a terminal connected to the wire.

13 . The electrical connector of claim 10 , wherein the housing has a front end portion, an accommodating portion receiving the base portion of the seal member, and an outer peripheral portion.

14 . The electrical connector of claim 13 , further comprising a mating-portion seal disposed on the outer peripheral portion of the housing, the mating-portion seal configured to be elastically deformed radially between the outer peripheral portion of the housing and the mating housing.

15 . The electrical connector of claim 13 , wherein the housing has a lock beam on the outer peripheral portion of the housing, the lock beam engaging the shell.

16 . The electrical connector of claim 13 , wherein the front end portion of the housing is positioned inside a metal member connected to the mating housing.

17 . The electrical connector of claim 13 , wherein the shell is integrally formed with a side wall enclosing the outer peripheral portion of the housing, an attachment portion extending at a front end of the side wall, and the bottom portion of the shell extending at a rear end of the side wall.

18 . The electrical connector of claim 17 , wherein the mating housing is inserted between the outer peripheral portion of the housing and the side wall of the shell.

19 . The electrical connector of claim 10 , wherein the seal member has a peripheral wall protruding from the base portion.

20 . The electrical connector of claim 19 , wherein the bottom portion of the shell has a peripheral groove receiving the peripheral wall of the seal member.
