The present disclosure relates to a condenser bushing including a condenser core and electrically conductive field-grading layers, which are embedded in insulating material of the condenser core and arranged around a central channel for conductor extending along an axis defining an axial direction, while an electric connection is provided to at least one of the field-grading layers, wherein pairs of neighbouring field-grading layers with the insulation material between them form sections of the condenser core of axial lengths L.sub.1 through L.sub.n and with capacitances C.sub.1 through C.sub.n, characterized in that a shape of at least one of the field-grading layers deviates from cylindricality in order to reduce non-uniformity of electric field stress of the condenser bushing compared to a corresponding condenser bushing with the cylindrical field-grading layers forming sections of the axial lengths L.sub.1 through L.sub.n and with capacitances C.sub.1 through C.sub.n.

The purpose of the present invention is to make it possible to easily attach an elastic water-stop member to a wiring member. The present invention is a wiring module (10) comprising a wiring member (20), and an elastic water-stop member (30) formed with a through-housing section (32) capable of housing a portion, in the longitudinal direction, of the wiring member, wherein the elastic water-stop member has a slit (36) formed from an outer peripheral portion thereof to the through-housing section, and the slit is kept closed in a state in which the portion in the longitudinal direction of the wiring member is housed in the through-housing section.

The purpose of the present invention is to provide a technology which can increase the versatility of a wiring module in which a grommet is provided to a wiring member. The wiring module comprises: a wiring member connecting a vehicle body and a door panel; and a grommet attached to the wiring member. The grommet includes a base part fixed to a fixed position with respect to the door panel. The wiring member includes a first segment, and a second segment which is positioned more on the vehicle body side than the first segment and is covered by the base part. The first segment of the wiring member is covered by a protective part which can be deformed by bending and/or deformed by expansion/contraction.

The present disclosure describes a grommet formed of a polymeric material and adapted for securing a cable within a cable hanger. The grommet includes a main body having a generally cylindrical profile, the main body further having a length, a thickness, and a longitudinal axis, a plurality of spokes extending radially inward from the main body at an oblique angle relative to the main body, and an annular inner wall coupled to the plurality of angled spokes and surrounding an interior cavity, wherein the annular inner wall extends the length of the main body. Other grommets and cable hanger assemblies are described herein.

The purpose of the present invention is to provide a wiring module in which both a grommet and a planar member are provided to a wiring member, wherein the assemblability into a door panel can be improved. The wiring module comprises: a wiring member; a planar member that holds the wiring member; and a grommet that is attached more toward a vehicle body side than the portion of the wiring member that is held by the planar member. The planar member includes: a main plate part that holds a section of the wiring member which extends along an inner plate part of a door panel; and a planar member-side attachment part that is attached to the grommet. The grommet includes: a base part that is fixed at a fixed position to the door panel; and a grommet-side attachment part to which the planar member-side attachment part is attached.

A method for manufacturing a ceramic substrate by a 3D-printing process is described. The method comprises operating a 3D-printer to print a green-state ceramic body having a height extending to spaced apart first and second end surfaces and at least one via extending at least part-way along the height of the green-state ceramic body from the first end surface toward the second end surface. Then, the green-state ceramic body is sintered to provide the ceramic substrate with the at least one via. In cross-section, the at least one via has a square-shaped via with rounded corners.
