Transformer for variable current charger

Abstract

The invention belongs to the technical field of transformers, and specifically relates to a transformer for a variable current charger, including a base; the top of the base is provided with a bobbin, the bobbin is provided with a coil, and the middle part of the bobbin is A magnetic core is provided, a workbench is provided on both sides of the bobbin, and a work slot is provided in the middle of the workbench, a copper sheet is pasted on the coil at the work slot, and the other end of the copper sheet is connected with a telescopic cavity, the telescopic cavity is provided with a telescopic column, the outer end of the telescopic column is provided with a slide plate, and the workbench on both sides of the working tank is provided with an arc-shaped groove, and the arc-shaped groove is slidably connected with an arc-shaped plate; In the present invention, a movable arc-shaped plate is arranged on the outside of the coil on the transformer, so that the outside of the coil can be effectively protected, and at the same time, the arc-shaped plate can move when the transformer is working and no longer wrap the coil, so that the coil can effectively dissipate heat , greatly improving the working quality and service life of the transformer.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a transformer for a variable current charger. Background technique [0002] As a common electronic component, the transformer is one of the important components of the variable current charger. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the magnetic core; the main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc.; For: power transformers and special transformers; transformers usually include a bobbin, two terminal blocks fixedly connected at both ends of the bobbin, a magnetic core, a coil, a wire and a terminal, etc., the magnetic core passes through the bobbin, and the coil Wound on the outside of the bobbin. [0003] The coils on the existing transformers for variable current ch...

Problems solved by technology

[0003] The coils on the existing transformers for variable current chargers are often exposed outside, so that the outer enameled wires on the coils are easy to peel off or break under the action of external force, thereby affecting the stable and effective work of the transformers. When the protective layer can protect the coil, although the protective layer can protect the coil to a certain extent, it will affect the normal heat dissipation of the coil when the transformer is working, thus affecting the working quality and service life of the transformer.
