A grommet unit to be attached to an attachment surface of an attachment-target body, the grommet unit including: a tubular grommet having a groove on a surface thereof; a bracket to be overlaid onto the grommet and press the grommet against the attachment-target body in a first direction; and a communication passage formed by covering the groove of the grommet with the bracket, wherein the communication passage has a first end that is in communication with a space between overlapping surfaces of the bracket and the attachment surface, and a second end that is in communication with a portion where the grommet and the bracket are not overlaid on each other.

A wire harness includes a cable and a holding member. The cable includes a twisted wire, and an insulation coating that coats the twisted wire. The cable has a bent portion. The holding member covers a range of the cable including the bent portion, and retains a shape of the bent portion. The twisted wire is in contact with the holding member at least in a part of the bent portion.

A bushing for gas-insulated switchgear has an electrical conductor, which has a longitudinal axis and which is embedded in an insulating material, and a coated electrode that is arranged coaxially spaced apart from the conductor and that is formed from a plurality of segments.

A grommet according to one aspect of the present disclosure includes: an annular mounting portion that is to be fixed to a surrounding portion of an insertion hole of a vehicle body panel; and a tubular stress-absorbing portion that includes a tubular side wall that extends from an inner circumferential rim portion of the mounting portion toward one side in an axial direction, and a bottom wall that partially closes off the tubular side wall at a front end of the tubular side wall. Furthermore, the grommet includes tubular insertion portions that are provided integrally with the bottom wall, and that cover the outer circumferences of wire harnesses inserted into the insertion hole. The mounting portion includes an annular seal portion that comes into close contact with the surrounding portion of the insertion hole of the vehicle body panel. The side wall is flexible.

An insertable high-voltage bushing includes an inner conductor which extends in a longitudinal direction between a high-voltage terminal and a plug-in section of the high-voltage bushing. The plug-in section is configured for the insertion of the high-voltage bushing into a device connection part of an electrical device. An insulating body at least partially extends around the inner conductor. A housing at least partially extends around the outside of insulating body. The housing includes a tubular housing element which extends between a head fitting at the high-voltage terminal of the high-voltage bushing and a mounting flange for fastening the high-voltage bushing to a device housing of the electrical device. The housing element is made of a composite material and a secondary insulation provided between the housing element and the insulating body is formed of a dry foam.

A cable harness grommet for installation in an aircraft interior component, and method of installing the same. The cable harness grommet seals a honeycomb panel cut-out and seals the cable harness itself as the cable harness passes through the cut-out by way of an aperture in the cable harness grommet. The honeycomb panel cut-out is enclosed by the cable harness grommet such that the cable harness grommet closes and seals the honeycomb panel cut-out and the aperture around the cable harness itself, both in compliance with applicable airworthiness requirements.

A waterproof connector that is easy to design and manufacture and that can provide sufficiently close contact with respect to a through hole including a tapered opening is provided. A sealing member that provides waterproofness of the waterproof connector includes an inner tube portion and an outer tube portion, and the connector body includes a holding projection. The holding projection is configured to be inserted between the inner tube portion and the outer tube portion from a rear side in an insertion direction and configured to push the outer tube portion against an inner circumferential face of the tapered opening when the sealing member is received between the outer circumferential face of the connector body and the inner circumferential face of the tapered opening.

A cable management system configured to account for and accommodate physical movement of the cables being managed. The cable management system includes an elastic element, such as a spring, to accommodate for the anticipated expansion and/or contraction movements of the cables being managed. The cable management system may be applicable for vertical cable installation projects that are installed in outdoor applications.

One aspect of the present disclosure provides a grommet that can improve water sealing property. A grommet main body according to one aspect of the present disclosure includes an opposing portion that opposes a circumferential portion of an attachment hole of a vehicle body panel and an annular seal portion that is provided in the opposing portion and is brought into tight contact with the vehicle body panel. The seal portion includes an annular first lip portion that extends from the opposing portion toward the vehicle body panel and an annular second lip portion that extends from the opposing portion toward the vehicle body panel and is provided radially inward of the first lip portion. The first lip portion is inclined radially outward toward the tip end of the first lip portion, and the second lip portion is inclined radially inward toward the tip portion of the second lip portion.

A sealing grommet for a sealed feedthrough of a strand-shaped element through a wall, in particular for a cable feedthrough for the automotive sector, is configured for insertion in an installation direction into an opening, bordered by the wall and with a predefined opening width. The sealing grommet has a grommet body with a push-through area which extends in the installation direction and which is fed through the opening in the installation direction during installation, in such a way that it engages behind the wall in the installed state. An auxiliary element facilitating the insertion into the opening is provided, which has a circumferential sliding area containing at least one sliding surface, and wherein the at least one sliding surface bears at least partially on a circumferential surface of the push-through area.
