The invention refers to an electrical connection (10) comprising a bushing (12) having a geometric central axis (14), an electrical conductor (16) passing through said bushing (12) along the geometric central axis (14), and an insulating layer (18) electrically insulating said bushing (18) from said conductor (16). It is suggested that the bushing 12, the insulating layer (18) and the electric conductor (16) are pressed together, preferably during a rotary forging process, in order to achieve a mechanical cold transformation.

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.

The invention relates to an electrical conductor for the conduction of electrical current through an opening of a housing wall, wherein the electrical conductor is enclosed, at least in a first sealing segment by a sealing body made from an elastic material. The electrical conductor can be inserted with the sealing body into an opening of a housing wall for sealing between sealing body and housing wall. The electrical conductor has a materially bonded connection to the sealing body, and a fastening part is provided on the conductor and has an axial through-opening through which the electrical conductor is inserted, wherein the fastening part extends radially, starting from the axial through-opening, in a first axial segment which has the maximum radial extension of the fastening part perpendicular to the axial through-opening. The fastening part has, on one side or two sides of the first axial segment, a second axial segment and/or a third axial segment respectively forming a radially circumferential separation region for a casting tool. The invention furthermore relates to a corresponding method for production.

The invention relates to an electrical conductor for conducting electrical current through a housing, wherein a sealing body made of an elastic material is arranged on the electrical conductor, wherein the sealing body encloses the electrical conductor in a first sealing section radially surrounding the electrical conductor, wherein a housing part is arranged on the electrical conductor. The housing part radially encloses at least part of the surface of the sealing body, which is not in contact with the electrical conductor in the first sealing section, in a second sealing section, wherein the elastic material of the sealing body comprises at least one hollow chamber and/or is an elastomer foam. The invention further relates to a corresponding method for manufacturing.

A sensor includes a sensing element, a first pair of lead wires, a second pair of lead wires, a grommet, and a shell. The first pair of lead wires is fixed to the sensing element and configured to receive signals from the sensing element. The second pair of lead wires is electrically connected to the first pair of lead wires at a joint. The second pair of lead wires is configured to receive signals from the first pair of lead wires. The grommet houses the joint, a portion of the first pair of lead wires, and a portion of the second pair of lead wires. The shell houses the sensing element, the first pair of lead wires, and the grommet. The shell engages and deforms the grommet to seal an interior space defined by the shell.

Embodiments of the present disclosure relate to a sealing arrangement of a bushing for a power electrical device and a bushing comprising the sealing arrangement. The sealing arrangement includes a top cover; a central conductor going through the top cover; a guide element having a cylinder portion and a flange portion extended from a middle part of the cylinder portion, wherein the cylinder portion is arranged between the top cover and the central conductor, and the flange portion is connected onto the top cover; a static sealing structure provided between the guide element and the top cover; and a dynamic sealing structure provided between the guide element and the central conductor. With the new sealing structure design, it could provide a good sealing performance so that the bushing can be used in various environments.

A feedthrough assembly may include a feedthrough conductor, a first insulator, and a first metal gasket forming a seal between the feedthrough conductor and the first insulator. The feedthrough assembly may additionally include a body, and a second metal gasket forming a seal between the body and the first insulator. Methods of manufacturing such feedthrough assemblies may include compressing the first metal gasket between the feedthrough conductor and the first metal gasket to form a seal therebetween. The methods may further include compressing the second metal gasket between the body and the first insulator to form a seal therebetween. Induction furnace systems may include one or more such feed assemblies.

The present disclosure relates to a bushing comprising a conductor tube, a support tube, arranged within the conductor tube, a draw-rod configured to run through the support tube, and a contact arrangement arranged to be drawn into the conductor tube by the draw-rod. The contact arrangement comprises a sealing plug arranged for sealingly engaging an inside wall of the conductor tube to prevent liquid from passing the sealing plug into the conductor tube.

An explosion-proof line bushing and method for producing the line bushing. A prespecified amount of elastomeric material is applied to a line and completely surrounds the line in a flat section in the circumferential direction. The line is inserted into a passage opening of a bushing body. The bushing body is preferably plastically deformed. After the plastic deformation, the elastomeric material substantially fills the volume remaining between the formed bushing body and line. The elastomeric material is elastically deformed and presses both against the line and the formed bushing body so that flame-proof gaps are formed between the bushing body and the line. The applied mass of the elastomeric material is determined depending on the inner volume between the formed bushing body and the line remaining.
