AI Technical Summary

Technical Problem

The pin surfaces of existing electronic transformer frames are relatively smooth, resulting in insufficient solder adhesion and making them prone to cold solder joints, which affects the soldering quality.

Method used

The device adopts a pin-connection design, including a fixing part and a connecting part. The connecting part is semi-conical with locking teeth and welding grooves on both sides. It is fixed to the frame body by injection molding. The wire is clamped between the locking teeth and wound around the winding groove. During soldering, the solder enters the locking teeth and welding grooves to form a strong solder joint.

Benefits of technology

This improves the welding strength between the coil wires and the connector pins and circuit board, reduces the occurrence of cold solder joints, and improves the quality of soldering.

Abstract

The utility model discloses an electronic transformer framework convenient for welding, which comprises a framework body and a plurality of plug pins, each plug pin comprises two welding pins with the same structure, and each welding pin comprises a fixing part and a plug part; according to the electronic transformer framework convenient to weld, the plug-in pins are fixed to the bottom of the framework body in an integrated injection molding mode, a wire of a transformer coil is clamped between the two welding pins, soldering tin is welded on the wire after the wire is wound around the wire winding groove, the plug-in parts of the welding pins are inserted into the pre-holes in the circuit board, the soldering tin is melted, and therefore welding of the transformer coil is facilitated. The soldering tin enters the two insertion-connection unavailable latches and the dissolving tank, so that the soldering tin can be firmly welded at the welding pin; the electronic transformer framework is firm in welding, the welding strength between the coil wires and the plug pins and the welding strength between the plug pins and the circuit board can be effectively reduced, the phenomenon of insufficient soldering is effectively reduced, and the welding quality of the transformer framework is improved.
