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.

An electrical feedthrough is providing that includes a base body, an insulating material, an electrical conductor, a creepage distance extension, and a sealing member. The base body has a through opening extending therethrough. The insulating material is in the through opening. The electrical conductor extends through the insulating material such that a portion of the electrical conductor protrudes from the insulating material. The creepage distance extension surrounds at least a section of the portion. The sealing member is between the insulating material and the creepage distance extension. The sealing member is a seal material that is at least partially mineral and crystalline.

A method for producing an electrical bushing with a multi-part inner conductor arranged at least in some sections in an outer tube made from metal and electrically insulated from the outer tube by an electrically insulating material. The inner conductor of the finished bushing has at least one contact section protruding out of the outer tube and a bearing section that is arranged within the outer tube and that is compressed with the electrically insulating material. The outer tube made from metal to form a composite for supporting the at least one contact section. The at least one contact section and the bearing section compressed with the electrically insulating material and the outer tube made from metal to form the composite for supporting the at least one contact section are prepared as separate assemblies and then connected to each other.

A winding configuration for a transformer or an inductor has a winding formed by a winding conductor, a solid insulation surrounding the winding and a connecting unit embedded in the solid insulation. The aim is to obtain a winding configuration which provides the required dielectric strength even at higher operating voltages. In order to achieve this goal, the connecting unit is a plug lead-through and is configured to allow the connection of a cable connector.

A high-voltage feed-through contains a securing flange for securing the high-voltage feed-through to a wall. The securing flange contains a retaining part and a moving part, wherein the moving part is mounted relative to the retaining part such that it can rotate in relation to a longitudinal direction of the high-voltage feed-through. An electrical device contains a fluid-tight housing and the high-voltage feed-through. A device connection part is provided for receiving and contacting the high-voltage feed-through.

A cable-gland system provides a sealing function to openings in an electronic chassis that receive cables. The cable-gland system comprises a plurality of individual cable glands. Each of the plurality of individual cable glands includes an exterior end to be positioned adjacent an exterior of the chassis, and an interior end for positioning within the chassis. Each of the plurality of individual cable glands includes a through-hole extending between the exterior and interior ends for receiving one of the cables, and an outer surface between the exterior and interior ends. Each of the plurality of individual cable glands has a male projection on one side of the outer surface and a female recess on an opposing side of the outer surface. The cable glands are connectable to form the cable-gland system by mating the male projection on one cable gland with the female recess of an adjacent cable gland.
