Device for detachably fixing a current conductor to a current transformer housing

A device comprising:

• a current conductor (1),
• a current transformer housing (2),
• a retaining element (3) with a first longitudinal axis defined thereon, wherein the retaining element (3) is guided through the current transformer housing (2),
• a fastening element (4) with a second longitudinal axis defined thereon, wherein the fastening element (4) is guided through the retaining element (3), and
• a clamping element (5),
• wherein the fastening element (4) and/or the retaining element (3) are seated against at least some regions of the surface of the current conductor (1) when the current conductor (1) is fastened to the current transformer housing (2),
• wherein the fastening element (4) can be rotated in a rotatory manner about the second longitudinal axis so as to fasten or detach the current conductor (1), and
• wherein the clamping element (5) is movably arranged on the current transformer housing (2) so that, in a first position, the clamping element (5) allows a translatory displacement of the retaining element (3) along the first longitudinal axis so as to fasten or detach the current conductor (1) and, in a second position, the clamping element (5) prevents the translatory displacement of the retaining element (3) along the first longitudinal axis so as to detach the current conductor (1).
