An electronic transformer with anti-corrosion function

Abstract

An electronic transformer having an anti-corrosion function includes a base, a cover shell, a winding frame, a magnetic core and a fixed connecting piece. A buckle is arranged on the edge of the base,one side of the edge of the cover shell is provided with a clamping groove, and a first cavity is formed internally after the cover shell and the base are clamped. An embedding groove is formed in the first cavity, and the joint of the embedding groove and the cover shell is provided with a lead. The outer surface of the cover shell is coated with a layer of anti-corrosion film. The center of thewinding frame is provided with a through hole, and the through hole forms a cavity which is called a second cavity. The winding frame is disposed in the first cavity, the bottom of the winding frameis provided with a wiring base, and the lower end of the wiring base is provided with a plurality of wiring terminals. A replaceable insulating pad assembly is arranged between the magnetic core and the winding frame. The magnetic core is cylindrical, and a coil is wound around the outer surface of the magnetic core. The fixed connecting piece is disposed on the outer surface of the base.

Description

technical field [0001] The invention belongs to the technical field of transformer manufacturing technology in integrated circuits, and in particular relates to an anti-corrosion electronic transformer. Background technique [0002] Transformer is a magnetic component often used in various electrical equipment. It uses the principle of electric energy and magnetic energy conversion induction to adjust different voltages so that it can reach the applicable range of electrical equipment; according to the prior art, the transformer mainly has the following forms: The primary coil and the secondary coil are sequentially wound on a single bobbin, and the core is combined to the bobbin through the through hole of the bobbin; in order to avoid leakage or other accidents, an insulating pad is usually provided between the core and the bobbin, but The magnetic core generates heat during operation, which promotes the aging of the insulation pad and reduces the service life of the trans...

Problems solved by technology

[0004] The object of the present invention is to provide an electronic transformer with anti-corrosion function. The anti-corrosion film provided on the cover shell solves the problem that when the transformer is used for a long time, it will not be corroded by external acid and alkali liquids and affect the work of the transformer. , the cover shell and the bracket are equipped with shock-absorbing materials, which achieves the effect of shock absorption when the electronic transformer collides and falls
