Abstract

A connector includes a connector housing and a shield shell. A terminal electrically connected to an end part of a wire is arranged inside the connector housing. The connector housing includes an inserting portion to be inserted into a mounting hole provided in a conductive case for accommodating an inverter and an outer arrangement portion integral with the inserting portion and to be arranged outside the case. The shield shell includes a tubular covering portion for covering an outer periphery of the outer arrangement portion and is electrically connected to the case. A shield-side sealing member seals between an outer-peripheral surface of the outer arrangement portion and an inner-peripheral surface of the covering portion. The outer-peripheral surface of the outer arrangement portion has a second intrusion suppressing groove provided over the entire outer periphery of the outer arrangement portion between the shield-side sealing member and the inserting portion.

First claim

What is claimed is:

1. A connector, comprising:
a connector housing including an inserting portion to be inserted into a mounting hole provided in a conductive case for accommodating a device to be installed in a vehicle and an outer arrangement portion integral with the inserting portion and to be arranged outside the case, a terminal electrically connected to an end part of a wire being arranged inside the connector housing, the outer arrangement portion including a first groove provided over an entire outer periphery of the outer arrangement portion;
a shield shell including a tubular covering portion for covering an outer periphery of the outer arrangement portion, the shield shell being electrically connected to the case; and
a shield-side sealing member provided in the first groove and configured to seal between an outer peripheral surface of the outer arrangement portion and an inner peripheral surface of the covering portion,
wherein at least one of a first facing surface of the covering portion facing the connector housing, a second facing surface of the covering portion facing the case and the outer peripheral surface of the outer arrangement portion includes a second groove provided over the entire outer periphery of the outer arrangement portion between the shield-side sealing member and the inserting portion,
the second groove is provided at least in the outer peripheral surface of the outer arrangement portion, and
the second groove provided in the outer peripheral surface of the outer arrangement portion overlaps an end surface of the covering portion at a side of the inserting portion in a facing direction of the outer peripheral surface of the outer arrangement portion and the inner peripheral surface of the covering portion.

2. The connector of claim 1 , wherein:
an end surface of the covering portion at a side of the inserting portion is the second facing surface facing the case, and
the second groove is provided in the second facing surface.

3. The connector of claim 2 , wherein:
an end part of the covering portion at the side of the inserting portion includes a cut portion penetrating through the end part of the covering portion in a facing direction of the outer peripheral surface of the outer arrangement portion and the inner peripheral surface of the covering portion, and
the cut portion communicates with the second groove provided in the second facing surface.
