Description

Improvement type SMT paster transformer

Technical Field

The utility model relates to a paster transformer technical field specifically is an improvement type SMT paster transformer.

Background

The transformer is a device for changing an ac voltage using the principle of electromagnetic induction, and its main components are a primary coil, a secondary coil, and an iron core. The main functions of the transformer are: the surface mount transformer adopts enameled wires to wind coils, and then wire ends are welded with pins. Because the enameled wire is comparatively fine, all can be impaired or break receiving collision, extrusion, welded in-process, not only use inconveniently, lead to the transformer to scrap easily moreover, in addition, the paster transformer can produce a large amount of heats using, and its itself lacks heat abstractor, and long-time use can make the heat constantly pile up to lead to burning out.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an improvement type SMT paster transformer for overcome the above-mentioned defect among the prior art.

According to the utility model discloses an improvement type SMT paster transformer, be in including base, safety cover, setting coil assembly and support on the base, both sides are equipped with the lock recess that bilateral symmetry set up around the base, the bottom of base is equipped with the heat-conducting plate, the left and right sides of heat-conducting plate has set firmly the heating panel that upwards extends the setting, the top of heating panel is equipped with first wedge, the left and right sides of safety cover is equipped with the assembly groove, the top of assembly groove be equipped with be used for in the second wedge of first wedge cooperation installation, be equipped with in the safety cover be used for lock recess cooperation connection's shell fragment spare.

According to a further technical scheme, pins are further arranged on the front side and the rear side of the base.

According to the technical scheme, open grooves used for being installed in a matched mode with the pins are formed in the front side and the rear side of the protection cover.

According to a further technical scheme, one side, far away from the heat conducting plate, of the heat dissipation plate is provided with a plurality of groups of heat dissipation fin strips which are arranged at equal intervals.

According to a further technical scheme, heat dissipation glue is coated between the base and the heat conduction plate.

According to a further technical scheme, the heat conducting plate and the heat radiating plate are of an integrated structure.
