A connector adapted to secure an electrical power line entering an electrical meter box comprises (a) a cylindrical member adapted to be at least partially inserted into the meter box through an access hole, (b) a flange affixed to or integral with a first end of the cylindrical member and (c) a cylindrical grommet selectively insertable at least partially into a second end of the cylindrical member and securable therein. The flange remains outside of the meter box and abuts an outer surface of the wall of the meter box or abuts a gasket sandwiched between the flange and the outer surface of the wall of the meter box. The cylindrical member, the flange, and the grommet all have aligned through-holes through which the power line passes as the power line enters the meter box.

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.

An electric plug-in device, which is suitable for plugging into an electric receiving device, has an inner conductor and an insulating body which encloses the inner conductor. The plug-in device has: a main element, which can be fixed indirectly, in particular with the involvement of a housing wall, or directly to the receiving device and which encloses the inner conductor and insulating body; a pusher element, which can be displaced relative to the main element; and a spring device, which, after the plug-in device has been plugged into the receiving device, exerts an axial spring force on the pusher element in the direction towards the receiving device.

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.

A wall bushing, comprising a head assembly, a conductive rod, and a connecting terminal sealing and covering the head assembly and the conductive rod. The connecting terminal and the conductive rod are electrically connected. The head assembly includes a transition tank and a transition plate that are connected to each other. An upper end of the transition tank is provided with a first through hole, and a lower end of the transition tank is hole-through. The transition plate is provided with a second through hole. The conductive rod extends through the first through hole and the second through hole. The transition tank and the transition plate are fixedly connected such that an accommodation cavity is formed around the conductive rod and in the transition tank and.

A feed-through and sealing arrangement of an electrical connection fed through a housing wall of an electric motor or another electric device, the feed-through and sealing arrangement including a terminal pin plate through which a terminal pin is fed, at least one feed-through opening, a sealing surface, and a combined sealing part. The at least one terminal pin cover is inserted into the at least one feed-through opening when feeding-through the terminal pin through the housing wall.

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 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.

Busbar comprising a supporting body (1) made of a tough-hard material, and at least one electrical conductor (2.1, 2.2, 2.3, . . . ), wherein the conductor (2.1, 2.2, 2.3, . . . ) is connected to the supporting body (1). The supporting body (1) comprises a seal (3) that is made of a rubber-elastic material, which encloses the conductor (2.1, 2.2, 2.3, . . . ) on the outer circumferential side with an annular sealing region (4) in a sealing manner.
