Abstract
The utility model discloses a protector for circuits, which comprises a housing. The inner of the housing is provided with two opposite iron core coils, wherein, at least one of the iron core coils can be moved. The winding directions of the two iron-core coils are opposite. The movable iron core coil is connected with a resetting device and a positioning device. Lead wires of the two coils are contacted through two conducting bodies and the two conducting bodies are respectively arranged on the iron cores. The circuit is cut off and the protector for circuits is not needed being disassembled and replaced when used. Only the positioning device is started, and the iron core coils are reset, and thus the utility model has the advantages of convenience and safety.
Description
The utility model relates to safeties, specifically belongs to the electric appliance circuits protector.
At present, the circuit protector uses fuse widely, and when circuital current was excessive, the fuse protection circuit need be changed fuse when reusing, and changes comparatively trouble.
The purpose of this utility model is to provide a kind of electrical equipment protector of iron-core coil, need not to change behind the cut-out circuit.
The technical solution of the utility model is: it comprises housing, be provided with two in the housing relatively, and wherein has a movably iron-core coil at least, two iron-core coils around on the contrary, movably iron-core coil is connected with resetting means, positioner, two winding wires are crossed the conductor contact, and two conductors are located on the iron core respectively.
When this insurance circuit device used, the two repulsive force deficiencies that produce magnetic pole of the same name relative to iron-core coil moved iron-core coil under normal current.When electric current is excessive; the repulsive force of the magnetic pole of the same name that iron-core coil produces moves iron-core coil; thereby make the free of conductors of two winding wires; cut off circuit and protect electrical equipment; positioner then makes the moving iron core coil location in released state, reuses and protects when testing device, only needs to start positioner; the moving iron core coil is resetted get final product, need not the dismounting and change protector.It is comparatively convenient to use.
