Abstract

The present disclosure provides a connector that can suppress deterioration of sealability of a case-side seal member between a case and a connector housing due to contact with a liquid including a salt. The connector 20 includes a connector housing 23 and a shield shell 24 . Inside the connector housing 23 , terminals 22 electrically connected to the ends of electric wires 21 are arranged. The connector housing 23 includes an insertion portion 31 that is inserted into a mounting hole 15 provided in a conductive case 12 that houses an inverter, and an outer placement portion 41 that is provided integrally with the insertion portion 31 and that is disposed outside the case 12 . A case-side sealing member 61 seals a clearance between an outer peripheral surface of the insertion portion 31 and an inner peripheral surface of a mounting hole 15 . A shield shell 24 is electrically connected to the case 12 and covers an outer periphery of the outer placement portion 41 . The insertion portion 31 has a first intrusion suppression groove 38 continuously provided over the entire circumference of the insertion portion 31 in a portion between the case-side sealing member 61 and the outer placement portion 41 on the outer peripheral surface of the insertion portion 31.

First claim

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; a case-side sealing member for sealing between an outer peripheral surface of the inserting portion and an inner peripheral surface of the mounting hole; and a shield shell to be electrically connected to the case, the shield shell covering an outer periphery of the outer arrangement portion, wherein the inserting portion including a groove continuously provided over an entire periphery of the inserting portion in a part of the outer peripheral surface of the inserting portion between the case-side sealing member and the outer arrangement portion.

2 . The connector of claim 1 , wherein the inserting portion includes the groove provided in an end part on the side of the outer arrangement portion on the outer peripheral surface of the inserting portion, and an end of the groove on the side of the outer arrangement portion reaches an end surface of the inserting portion on the side of the outer arrangement portion.

3 . The connector of claim 1 , comprising an auxiliary sealing member for sealing between the outer peripheral surface of the inserting portion and the inner peripheral surface of the mounting hole by being arranged in the groove.

4 . The connector of claim 1 , wherein the inserting portion includes a plurality of the grooves.

5 . 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; a case-side sealing member for sealing between an outer peripheral surface of the inserting portion and an inner peripheral surface of the mounting hole; and a shield shell to be electrically connected to the case, the shield shell covering an outer periphery of the outer arrangement portion, the mounting hole having an inclined surface on an outer opening of the mounting hole, the inclined surface being inclined to increase an opening area of the mounting hole from an inner opening end side of the mounting hole toward an outer opening end of the mounting hole, the inserting portion including a groove continuously provided over an entire periphery of the inserting portion in a part of the outer peripheral surface of the inserting portion between the case-side sealing member and the outer arrangement portion.
