Enameled aluminum wire winding and preparation method thereof

An enameled aluminum wire winding, comprising a framework, at least one connection terminal, and an enameled aluminum wire, the connection terminal comprising a fixed part one end of which extends to form a welded part, and the other end of which extends to form an external connection part, the fixed part of the connection terminal being fixed to the framework, the enameled aluminum wire being wound on the framework, a contact portion of the enameled aluminum wire being welded with the welded part of the connection terminal to form a connection section;

• the enameled aluminum wire winding being characterized in that further comprises a protective cover, the protective cover is provided with at least one glue groove in which insulating glue is contained, the connection section is submerged in the insulating glue and then the insulating glue is solidified thereby forming insulating glue solidification which enwraps the connection section and cements the protective cover together, wherein
• at least one supporting step is provided on the framework, the fixed part is fixed on the supporting step, the welded part passes through the supporting step, and the protective cover is engaged with the supporting step, and wherein
• a wire slot is formed at one side of the supporting step adjacent to the framework.
