Abstract

The invention relates to an electronic transformer which comprises a framework, a magnetic core set, an inner insulation cover and an outer insulation cover. A primary coil and a secondary coil are wound around two winding frames of the framework. The framework around which the coils are wound is sleeved with the inner insulation cover. The magnetic core set is assembled in the framework sleeved with the inner insulation cover. The transformer further comprises the outer insulation cover which is a square thin-wall shell with an opening formed in the bottom face. A large heat dissipation hole is formed in the top of the outer insulation cover and the whole top face of a cover body of the inner insulation cover is exposed. The upper plane and the side planes of a pin platform of the framework are coated with the cover edges of the inner insulation cover, so that the coils of the transformer and magnetic cores are insulated. The magnetic core set is glued and fixed at connecting seams and glued and fixed to the inner insulation cover. The opening in the bottom face of the outer insulation cover is fastened to an assembling platform of the inner insulation cover and used for insulating a transformer body from elements on the periphery of the transformer.

Description

technical field [0001] The invention relates to an electronic transformer, in particular to a transformer skeleton, an inner insulating cover and a manufacturing method of the transformer, which can ensure the electrical distance between coils, between the coil and the magnetic core, and between the transformer body and surrounding components and have a high degree of automation. . Background technique [0002] Electronic transformers have various types to meet the needs of different functions, and are usually used for isolation, voltage change, current change, impedance matching, etc., among which isolation is one of the main characteristics of transformers. Occasions used for isolation often have very strict safety performance requirements, such as circuits where the primary side is directly connected to the AC power grid and the secondary side is in contact with the user. Only after the safety test can ensure the safety of use. In order to meet the requirements of safet...
