Abstract: A closed-loop current transducer comprising a magnetic circuit core made of a material with a low magnetic reluctance to conduct magnetic flux and concentrate a magnetic field, a magnetic field detector positioned in a magnetic circuit gap of the magnetic circuit core, and a compensation coil assembly comprising a compensation coil and a compensation coil support comprising a coil support bobbin, the compensation coil being wound around the coil support bobbin. The magnetic circuit comprises a first longitudinal branch, a second longitudinal branch, and first and second end branches interconnecting the first and second longitudinal branches such that the branches surround a central opening configured to receive one or more primary conductors therethrough, the magnetic circuit being formed of first and second parts assembled together from opposed ends of the compensation coil support.

Abstract: A current transducer including a housing comprising an outer casing, a magnetic circuit core configured to encircle at least one primary conductor, and a magnetic field detector positioned in a magnetic circuit gap of the magnetic circuit core. The housing further includes an inner support part comprising a main body portion and a magnetic core support portion. The magnetic circuit core is in the form of a thin strip of amorphous material supported on the main body portion and magnetic core support portion, the magnetic circuit gap being formed between overlapping ends of the strip.

Abstract: Electrical current transducer including a housing (5), a magnetic field detector device (3) comprising a magnetic field sensing element (11), and a magnetic circuit comprising a magnetic core (4) with a gap (6) and a bridging device (8) mounted on the magnetic core and spanning across the gap. The bridging device comprises a gap-width setting portion (26) made of a non-magnetic material inserted in the gap configured to determine a minimum width of the gap. The bridging device comprises at least two parts (8a, 8b), a first part mounted against a first lateral side (14a) of the magnetic core and a second part mounted (8b) mounted against a second lateral side (14b) of the magnetic core opposite the first lateral side, at least one of the first and second parts comprising fixing extensions (30) cooperating with the other of the first and second parts configured for clamping together the first and second parts around a portion of the magnetic core comprising the gap.

Abstract: The invention relates to an attachment fastener that comprises a body (1) extending in an axial direction, with a head (2), a leg (3) and a skirt-shaped flexible collar (4) provided between the head (2) and the leg (3), and annular sealing washer (5) for sealing the length of a peripheral edge (42) of the collar (4), said sealing washer (5) having a lower surface (57) directed towards the opposite side of the collar (4) having at least one annular bead defining a first sealing line on the lower surface (57) of the washer (5). The sealing washer (5) is adapted to be removably attached onto said peripheral edge (32) of the collar (4), and comprises an upper surface opposite the lower surface (57), which defines an annular shoulder protruding on the side of the collar (4) and on which bears said peripheral edge (42) of the collar (4), said annular shoulder defining another sealing line on the upper surface of the washer (5).

Abstract: For fastening a coupling (1) formed from one plug-in part (2) and one sliding part (4) to a carrier part, a retaining arrangement (9) constructed of at least one side part (10, 11) from each opposite side is proposed. Each of the side parts (10, 11) has a spring arm (20) to which a bracket (23) is attached that grips the shaped collar (6) of the plug-in part (2) from behind in such a way that the collar (6), after pushing in the plug-in part (2) from the entry side (14), is in contact with a termination rib (24). Thus the plug-in part (2) is left fixed on the carrier part without both parts (2, 4) of the coupling (1) having to be plugged together when the sliding part (4) is slid.

Abstract: A device for compensating for tolerances when fastening an add-on to a base member comprises a holding element (1) connectable to the base member, and an elongate compensating bushing (8) that is associated with the add-on, is displaceable relative thereto, and comprises a channel (11) for accommodating a connecting element connectable to the add-on. The holding element (1) and the compensating bushing (8) are freely displaceably associated with each other via wall sections (6, 7) that are smooth over a displacement path. The channel (11) of the compensating bushing (8) has a larger dimension in a direction transverse to the longitudinal direction than the diameter of a connecting element. The holding element (1) is configured as bendable in at least one intermediate section located between a fastening region (2) to the base member and an accommodating region for the compensating bushing (8). This results in excellent tolerance compensation characteristics combined with ease of installation.
