Abstract

The invention discloses a method for manufacturing a transformer framework mounted with a low-voltage coil, which comprises the following steps: a, continuously punching a copper strap to form a coil blank strap through a coil blank die; b, continuously conveying the coil blank strap to a bending molding die, and processing each coil blank on the strap into a mounted low-voltage coil which comprises a coil part and two extension lines which are extended to the positioning edges of the copper strap from two ends of the coil part and form an included angle of 85 to 95 degrees with a cross section of the coil part; and c, feeding the strap manufactured in step b and provided with a plurality of mounted low-voltage coils into a die cavity of a framework die, making the strap into the framework through an insert molding process, and embedding each mounted low-voltage coil on the strap into a corresponding low-voltage coil area of the framework to form a whole member. The low-voltage coil is an integral member punched by the copper strap, has good consistency, can be produced in batch, and lowers the manufacturing cost; and the coil part is wrapped by a framework plastic material, does not loosen, and can meet the mounting process of a circuit board.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a transformer skeleton embedded with a low-voltage coil and a manufacturing method thereof. The low-voltage coil and the plastic skeleton are combined into an integral component through an insert injection molding process, which is used for the winding of the subsequent high-voltage coil. It is convenient for the manufacturing and mounting process of the transformer. Background technique [0002] The transformer bobbin is used to carry the high-voltage winding and the low-voltage winding. The traditional transformer bobbin includes a plastic bobbin, with a magnetic core hole in the bobbin, pin seats extending from both ends, and a high-voltage coil slot and a low-voltage coil slot on the bobbin. In the subsequent process, the high and low voltage coils are respectively wound in the high and low voltage coil areas by a winding machine, and then the terminals of ea...
