A ceramic subassembly manufactured by a 3D-printing process is described. The ceramic subassembly comprises a ceramic substrate having a sidewall extending to spaced apart first and second end surfaces. At least one via extends through the substrate from the ceramic substrate first end surface to the ceramic substrate second end surface. In cross-section, the via has a square-shape with rounded corners.

A wire harness includes an electric wire, a braided conductor covering the electric wire, a grommet having a tubular insertion portion through which the electric wire and the braided conductor are inserted, a water stop sheet sandwiched between an inner peripheral surface of the insertion portion and the braided conductor, and a fixture attached to the insertion portion so as to reduce a diameter of the insertion portion. The water stop sheet includes a base material layer having a plurality of pores communicating with each other in a thickness direction of the water stop sheet and a sealing compound layer laminated on the base material layer. The sealing compound layer is deformed so as to enter gaps between thin conductor wires constituting the braided conductor and the pores of the base material layer.

A grommet includes a fitting body causing a fitting groove to be fitted to a circumferential edge of a through hole, and a first tubular body and a second tubular body. The fitting body includes a tubular portion, a rib rising from an outer circumferential wall surface of the tubular portion, and a locked portion disposed radially inside the rib, rising from the outer circumferential wall surface, and configured to be locked to an outer circumferential surface of the first tubular body, to suppress elastic deformation of the tubular portion or reduce elastic deformation amount. The rib is elastically deformable in a circumferential direction, and the outer circumferential wall surface has a plurality of projection groups constituted by the locked portion and a plurality of ribs disposed radially outside the locked portion.

Pass through plates comprise a body with an opening between opposed first and second surfaces for accommodating the passage of electrical elements. One or more upper retaining elements project outwardly from the body and are positioned adjacent a body top portion. One or more lower retaining elements project from the body and are positioned adjacent a body bottom portion. The upper and lower retaining elements are each configured to both engage respective top and bottom sections of an opening in an external object, and to engage a backside surface of the external object when installed within the opening to retain the pass through plate for attachment with the external object. The upper and lower retaining elements are positioned to enable movement of the pass through plate from an upward position in the opening to a downward position in the opening for fixed attachment with the external object.

A grommet includes: a water stop portion that has an annular shape and is inserted to a through hole formed in an attachment panel for stopping water; and a first partition wall portion and a second partition wall portion that are unit arranged to project toward a radially inner side of the water stop portion. The water stop portion includes: a first contact portion that is capable of coming into contact with a first side surface of a circumference edge portion of the through hole; a second contact portion that is capable of coming into contact with the first side surface; a groove portion formed in an annular shape between the first contact portion and the second contact portion; and a recess/protrusion portion that is formed on a circumferential wall inside the groove portion.

The invention relates to a grommet made of a material that is elastic at least in portions for receiving at least one elongate object for strain relief and sealing, comprising an outer frame element that can be opened along a slit and comprises at least two membranes that are spaced apart in the longitudinal direction of the elongate object to be received and each comprise a hole of equal size, so as to be flush with one another, for receiving the elongate object. The invention is characterised in that the respective hole of the at least two membranes contacts the material of the frame element on the side of the slit.

Grommet assembly and method for installing a grommet assembly in a penetration hole of a panel. In one embodiment, a grommet assembly is comprised of multiple parts, including end members having a diameter greater than the penetration hole, and a middle member having a diameter sized to fit within the penetration hole. Each of the members includes one or more conduit holes for a conduit that is routed through the penetration hole, and an installation slit disposed between an outer peripheral surface and a conduit hole.

An electrical conductor assembly includes an electrical conductor, an electrically insulating jacket disposed around a conductor section of the electrical conductor, an electrically conductive sleeve disposed around a first insulating jacket section of the insulating jacket, and an electrically conductive yarn for realizing an electric field control. The electrically conductive yarn is wound around a second insulating jacket section of the electrically insulating jacket in adjacent relation to the first insulating jacket section.

A grommet includes a tapered barrel part and a tape winding spatula part. The tapered barrel part includes a large diameter cylindrical portion, a small diameter cylindrical portion, and an elastic deformation portion disposed between the large diameter cylindrical portion and the small diameter cylindrical portion. A fitting groove to be fitted in a through hole of a panel, is formed on the large diameter cylindrical portion. A thick walled portion is formed on an inner side of the elastic deformation portion. The tape winding spatula part is connected to the small diameter cylindrical portion and holds a wire harness passed through therein.

An integrated insulator sealing and shielding assembly includes a rubber housing having a plurality of radial weathersheds and a tapered end adjacent an endmost radial weathershed. The tapered end has an outer surface with a ring extending outward from the outer surface. The ring is compressible. A metal end fitting is disposed adjacent to the endmost radial weathershed and receives the tapered end. The tapered end is received in a counterbore in the metal end fitting. The counterbore has a sealing surface so that interference of the ring with the sealing surface creates a compressive sealing force to form a seal.
