Description

A transformer core winding lead frame

technical field

The utility model relates to a transformer iron core winding lead frame.

Background technique

The traditional transformer core winding lead frame structure is mainly composed of a frame and a coil wheel whose shaft is connected to the frame. The copper wire coil is installed on the rotating shaft of the coil wheel. When the transformer core is wound, the coil wheel will automatically put the line. Since the winding of the transformer core requires a certain tension to wind the copper wire tightly, traditional people usually design simple tools (such as binding linen on the copper wire, and the linen is fixed by steel wires) to increase resistance to the copper wire. This simple tool not only has poor stability, but also is difficult to adjust the degree of tightness. In addition, when the coil wheel is unwound, the copper wire is easy to shake, which will affect the winding of the transformer core in severe cases.
