Abstract

A device connector 10 to be attached to a case C of a device includes: a housing 30 to be fitted in an attachment hole C 1 of the case C; a seal groove 41 provided in an inner housing 31 constituting the housing 30 , and having a back surface 42 disposed opposite an outer peripheral edge portion C 2 of the attachment hole C 1 of the case C; a face seal 43 fitted in the seal groove 41 to waterproof a gap between the outer peripheral edge portion C 2 of the attachment hole C 1 and the back surface of the seal groove 41 ; and a relief groove 57 disposed adjacently outside the seal groove 41 in an outer housing 50 constituting the housing 30 and along the seal groove 41 , and recessed upward relative to a lower surface of the tubular portion 51 of the outer housing 50.

First claim

The invention claimed is:

1. A device connector to be attached to a case of a device, the device connector comprising:
a housing to be fitted in an attachment hole of the case, the housing including:
an inner housing including a seal groove extending along an outer peripheral surface of an entire perimeter of the inner housing and a back surface of the seal groove disposed opposite an outer peripheral edge portion of the attachment hole of the case; and
an outer housing including a relief groove disposed circumferentially outward of and adjacent to the seal groove of the inner housing, the relief groove extending along the seal groove and being recessed relative to a surface of the outer housing opposite the outer peripheral edge portion of the attachment hole of the case; and

a seal member fitted in the seal groove to waterproof a gap between the outer peripheral edge portion of the attachment hole and the back surface.

2. The device connector of claim 1 , wherein the outer housing includes a void communicating with the relief groove.

3. The device connector of claim 2 , wherein the outer housing includes a first section having a first thickness and a second section having a second thickness smaller than the first thickness; and
the second section includes the void.

4. The device connector of claim 3 , wherein
the inner housing includes a flange protruding outward from the outer peripheral surface and extending for the entire perimeter of the inner housing;
the seal groove is defined by a surface of the flange opposite the outer peripheral edge portion of the attachment hole and a section of the outer peripheral surface of the inner housing closer to the outer peripheral edge portion of the attachment hole relative to the flange;
the outer housing includes a tubular portion including an inner surface opposite a distal end of the flange; and
the tubular portion includes the relief groove, in a surface opposite the outer peripheral edge portion of the attachment hole.

5. The device connector of claim 4 , wherein the void is formed in the tubular portion of the outer housing.

6. The device connector of claim 4 , wherein the outer housing includes a planar fixing piece extending outward from the tubular portion in a direction parallel to the outer peripheral edge portion of the attachment hole; and
the planar fixing piece includes a through hole into which a bolt is passed through in a thickness direction of the planar fixing piece.

7. The device connector of claim 4 , wherein the void includes a first opening in an outer peripheral surface of the outer housing and a second opening in an inner peripheral surface of the outer housing; and
The first opening and the second opening are away from each other in a direction in which the relief groove extends.

8. The device connector of claim 2 , wherein the outer housing includes a planar fixing piece extending outward from the tubular portion in a direction parallel to the outer peripheral edge portion of the attachment hole; and
the planar fixing piece includes a through hole into which a bolt is passed through in a thickness direction of the planar fixing piece.

9. The device connector of claim 2 , wherein the void includes a first opening in an outer peripheral surface of the outer housing and a second opening in an inner peripheral surface of the outer housing; and
The first opening and the second opening are away from each other in a direction in which the relief groove extends.
