Transformer framework preventing winding lead wire from crossing

Abstract

The invention provides a transformer framework preventing a winding lead wire from crossing. The transformer framework comprises a magnetic core groove and a winding framework body arranged at the endof the magnetic core groove; the outer wall of the magnetic core groove and the winding framework body form a winding groove for winding a primary coil and a secondary coil; the winding framework body comprises a primary framework body and a secondary framework body; the primary framework body extends outwards to be provided with a plurality of primary wire hanging columns distributed at intervals, each primary wire hanging column is provided with a primary pin perpendicular to the primary wire hanging column, and a primary wire crossing groove is formed in a gap of every two primary wire hanging columns; the primary framework body is provided with primary wire guiding grooves flush with or lower than the primary framework body and communicated with the primary wire crossing grooves, so that a lead wire of the primary coil winding the winding groove passes through the primary wire guiding grooves in a horizontal or obliquely-downward wire outlet mode, penetrates through the primary wire crossing grooves, bypasses the primary wire hanging columns and finally winds the primary pins, and a height difference is formed between the lead wire of the primary coil and the secondary coil winding the periphery of the lead wire. The transformer framework can achieve the full-automated production of a transformer.

Description

technical field [0001] The invention relates to a transformer for a charger, in particular to a transformer frame for preventing crossing of winding lead wires. Background technique [0002] The transformer is an important electrical device in the power output distribution system. It mainly includes a magnetic core, a transformer skeleton, a primary coil and a secondary coil, and uses the principle of electromagnetic induction to transmit electric energy. The primary coil is used to connect with the AC power supply and is wound on the winding slot of the transformer skeleton. The secondary coil is used to output the induced potential and is wound outside the primary coil. By setting multiple coil windings on the secondary coil, the output potential can be changed. potential level. However, for vertical transformer bobbins, such as Figure 9 As shown, the lead wire 41 of the primary coil and the bottom layer of the secondary coil 50 are attached to the surface of the primary...

Problems solved by technology

[0004] Therefore, in the production of the prior art, a layer of insulator is usually added to the stressed part of the secondary coil for protection. The insulator can be an insulating sleeve or an insulating tape. It is set or wrapped on the secondary coil of the transformer, which has the following defects: (1) due to the differences in the individual experience of the workers, the quality of the processed transformer is uncontrollable, and the quality is uneven, resulting in the outflow of defective products; (2) the transformer cannot be realized Fully automated production, poor production efficiency and low production capacity; (3) High labor costs
