Contact-pin-type current mutual inductor

The utility model discloses a contact-pin-type current mutual inductor. The contact-pin-type current mutual inductor comprises an electric assembly, a support and a protecting shell. The electric assembly comprises a mutual inductor magnet ring, a coil, primary side contact pins and secondary side contact pins. The middle portion of the support is provided with a hollow-out magnet ring bracket. The coil is wound on the mutual inductor magnet ring. The mutual inductor magnet ring is sleeved with the magnet ring bracket. The primary side contact pins penetrate through the free ends of the magnet ring bracket and expose out of the support. The secondary side contact pins are fixed on the support. The head end and the tail end of the coil are connected with the secondary side contact pins respectively. The electric assembly and the support are fixed on the outer portion of the protecting shell by glue pouring. According to the contact-pin-type current mutual inductor, the structure is simple, assembling is compact, the complicated threading procedure during the utilization process is avoided, the working hours are shortened, and the testing efficiency is improved. Due to the fact that primary side contact pin conductors, the magnet ring and the coil of the current mutual inductor are positioned inside the protecting shell, the safety during the utilization process is improved.
