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.

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.

An electrical induction device includes a housing and a contact arrangement in the housing of the electrical induction device for electrically contacting an electrical conductor. The contact arrangement includes a conductor tube, a receiver contact which is fastened to the conductor tube and configured to receive and electrically connect with the electrical conductor, and a resilient suspension arrangement fastened to the housing and connected to an outside of the conductor tube such that the receiver contact is resiliently movable in a plane which is parallel to a cross section of the conductor tube while being substantially immovable in an axial direction of the conductor tube.

An electrical bushing having an anti-rotation mounting flange for preventing rotation of a body element of the electrical bushing is provided. The electrical bushing includes a mounting flange, at least one locking element and a body element having a circumferential protrusion. At least one first recess is formed in the circumferential protrusion, and the at least one locking element is configured to engage with the at least one first recess and with the mounting flange for restricting relative rotation of the body element relative to the mounting flange about a longitudinal axis R. A further aspect provides an electrical transformer including at least one electrical bushing according to the above. A yet further aspect provides a method for mounting the electrical bushing according to the above.

A wall bushing for high voltage application is presented. The wall bushing includes a grounded shield. The grounded shield includes a grading ring in a distal end thereof. The grading ring has an elliptic cross section with conjugate diameters, wherein a major diameter of the conjugate diameters is arranged in an axial direction of the grounded shield and a minor diameter of the conjugate diameters is arranged in a radial direction of the grounded shield. The major diameter is larger than the minor diameter.

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.

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.
