Claim:
1. A detector for detecting at least one electrical quantity in an electrical conductor, the detector comprising a frame on which a mechanism is mounted, the mechanism comprising: a magnetic toroid divided into a first branch and a second branch, the toroid having a coil wound around one of the first and second branches; at least two jaws configured to anchor the detector on the electrical conductor, each jaw being rotatable about an axis defined by the frame between an open position and a closed position of the jaw, a bearing member including a bent wire defining two parallel sections each having a free end respectively disposed in each of two openings in the second branch, the bearing member being secured to the second branch of the magnetic toroid and defining at least one concave volume configured to partially receive the electrical conductor, the bearing member being configured to transmit to the second branch of the magnetic toroid a pre-closure torque to move the magnetic toroid to the pre-closure position, in which the electrical conductor is disposed in the bearing member and the bearing member is suspended from the second branch, wherein the jaws are configured to apply a clamping force to the electrical conductor, when the electrical conductor is disposed in the bearing member, wherein the first and second branches are respectively disposed in first and second casings, and the bearing member is mounted on the second casing, and wherein the bearing member is further configured to transmit, to the second branch, the clamping force exerted by the jaws on the electrical conductor and to move the second branch from the pre-closure position to the closed position.
