Bidirectional vehicle-mounted charger electric leakage detection device and production process thereof

The invention relates to the technical field of electronic components, in particular to a bidirectional vehicle-mounted charger electric leakage detection device which comprises a bottom plate, a magnetic ring, a leakage current detection winding, a protection shell and a common mode inductor winding, the magnetic ring is located above the bottom plate, the leakage current detection winding is wound on the outer side of the magnetic ring, the protection shell is arranged on the outer side of the leakage current detection winding, and the common mode inductor winding is arranged on the bottom plate. Pins of the leakage current detection winding penetrate through the protection shell, the multiple sets of common mode inductor windings are wound around the outer side of the protection shell, pins of common mode inductors penetrate through the bottom plate and are fixed to the bottom plate, and the protection shell is used for separating the leakage current detection winding and the common mode inductor windings.
