A grommet includes an opposing portion 32 that opposes a portion surrounding a mounting hole 12 in a vehicle body panel 11, and a second water-blocking portion 34 that extends from the opposing portion 32 and comes in contact with the vehicle body panel 11. The second water-blocking portion 34 is formed in an annular shape that is to surround the mounting hole 12. The second water-blocking portion 34 is provided with a base portion 40 that extends from the opposing portion 32 toward the vehicle body panel 11, a first lip portion 41 that extends from the leading end of the base portion 40 and comes in contact with the vehicle body panel 11, and a second lip portion 42 that extends from the leading end of the base portion 40 and comes in contact with the vehicle body panel 11.

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 method for developing an epoxy resin impregnated glass fiber Direct Current (DC) bushing, comprising: according to length parameters of each layer of capacitive screen or resistive screen designed depending on insulation requirements, selecting bushing design parameters, determining a winding machine program according to the bushing design parameters, and winding a core body according to the winding machine program, wherein during the core body winding process, the core body begins to be initially cured; after the core body is wound, curing the core body by an oven according to a preset oven temperature and duration; machining the cured core body according to a preset core body design drawing; after the inner wall of a flange is polished and cleaned and is heated and pretreated by the oven, injecting glue at the position of a glue injection hole of the flange for gluing the core body and the flange; sequentially assembling a collector ring, a hollow composite insulator, and a voltage-equalizing sealing cover on the glued core body, and mounting a conducting rod, a wiring board, and a voltage-equalizing ball; and performing various tests on the bushing according to a preset bushing standard for a DC system.

An aspect of the present disclosure provides a shield for a terminal of a high-voltage electrical device including a first shield element having at least one axial opening and at least one lateral opening, and at least one second shield element, wherein the at least one second shield element is moveable between a first shield position and a second shield position for selectively opening and closing at least one of the at least one axial opening and the at least one first lateral opening. Further aspects provide a high-voltage electrical bushing comprising a shield according to the aspect above, and a transformer including said high-voltage electrical bushing. Yet a further aspect provides a method for installing a high-voltage bushing having a shield according to the aspect above.

The invention is concerned with a bushing for high voltage applications and a bushing arrangement including such a bushing. The bushing includes a conductor defining a longitudinal axis (A) through the bushing where the bushing has a central section and a first and a second peripheral section on opposite sides of the central section along the longitudinal axis (A) and includes an optical fibre with a first part (P1) stretching through the central section, the fibre being adapted to detect physical properties being influenced or caused by the operation of the bushing. The sections are sections of a solid condenser core and the bushing further includes an enclosure for a length of fibre that is to exit the bushing, the enclosure being buried in the central section adjacent the surface of the condenser core and having an interior volume.

A seal structure that includes: a grommet with a cylindrical shape that is installed in an attachment panel, the grommet including an opposing surface facing an attachment surface of the attachment panel; and a bracket that presses the opposing surface of the grommet against the attachment surface of the attachment panel.

The present disclosure describes grommets formed of a polymeric material and adapted for holding a plurality of discrete cables. A grommet may comprise two halves, each half comprising: a main body having a generally arced outer surface, a plurality of angled cantilevered tines integrally coupled to the main body and extending generally radially inward from the main body; and a slidable interconnection feature integral with the main body, wherein the slidable interconnection feature for each respective half is dimensioned to mate with the slidable interconnection feature of the other half, allowing the two halves to slide into an interlocking position with each other when compressed together.

For example, in an earphone in which left and right earphone units are connected by a cable and a remote part or a battery part is interposed on the cable, a bush structure is provided to a part where the cable is led out of the remote part and the like and suppresses the occurrence of disconnection in the vicinity of the lead-out part. The bush structure is provided to a lead-out part 5a of a cable 4 and includes a bush body 2 provided to the lead-out part and formed with a first through hole 2a2 where the cable is inserted. The first through hole gradually increases in diameter toward a lead-out direction of the cable.

A grommet includes a water stop part having an annular shape that stops water by being inserted into a through hole formed on a mounting panel, and a first partition wall part or a second partition wall part disposed so as to close the annular shape of the water stop part by extending in a radially inner side of the water stop part. The water stop part includes an abutting surface formed in an annular shape capable of coming into contact with one side of a peripheral part of the through hole in an axial direction, and a plurality of claw parts that face the abutting surface in the axial direction, that are capable of coming into contact with another side of the peripheral part of the through hole, and that are intermittently provided in a circumferential direction.
