Planar groove intermediate-frequency continuous quenching sensor

The utility model provides a planar groove intermediate-frequency continuous quenching sensor. The planar groove intermediate-frequency continuous quenching sensor comprises a heating effective wire, a cooling water jet, a omnibus bar and insulation connecting plates, the two ends of the heating effective wire are connected with a water inlet pipe and a water outlet pipe, an upper current conduction body and lower current conduction bodies are embedded on the inner side of the heating effective wire, the cooling water jet is arranged on one side of the heating effective wire, and an upper insulation connecting plate and a lower insulation connecting plate are arranged between the cooling water jet and the heating effective wire. According to the planar groove intermediate-frequency continuous quenching sensor, electric current density is reasonably distributed, a planar groove can perform heating and quenching at the same time, a hardened layer is continuous and even, the production efficiency is high, the st
