Novel coil structure

The utility model provides a novel coil structure, and belongs to the technical field of valves. A novel coil structure comprises a framework, a coil, a coating layer and a metal inserting piece. According to the utility model, the cladding layer is melted and then poured in the area where the coil is wound on the skeleton, the area where the metal insert is inserted in the skeleton, and the areawhere the joint of the coil is connected with the metal insert; the coating layer forms a whole body; therefore, the coil structure is integrally formed; according to the coil structure, the sealing performance and the insulation performance of the coil structure are improved, the product performance is better, the coil can be better protected, the service life of the coil is prolonged, complex and tedious operation steps such as winding an insulating tape outside the coil and pouring insulating resin to the joint of the metal inserting piece are not needed, and the production efficiency is higher. 本实用新型提供了一种新型线圈结构，属于
