Abstract
The utility model discloses a novel high-frequency transformer, comprising a framework, a magnetic core, a primary coil, a secondary coil and an upper shield. The magnetic core is fixed on the framework. The upper shield is used for covering the primary coil and secondary coil on the framework. The transformer is characterized in that the upper shield is provided thereon with a shielding layer. The transformer provided by the utility model has the beneficial effect that the shielding layer is a metal plate and arranged on or clipped on the upper shield, so that the metal plate can generate a shielding effect and weaken magnetic lines of force emitted by the transformer to a housing of an electronic product, thereby preventing convergency of the magnetic lines of force in the housing and generation of a relative heavy eddy current at a certain position to avoid damage to the housing caused by a overhigh temperature.
Description
Technical field
The utility model relates to the high frequency transformer structure, relates in particular to a kind of novel high-frequency transformer.
Background technology
High frequency transformer is used for electronic product, like TV, computer etc.; And electronic product also trend in slimming.How the used magnetic core combination of high frequency transformer can leave the space is satisfied the inductance of electronic transformer and the requirement of leakage inductance.So, the magnetic line of force of magnetic core combination gap will to around disperse, the magnetic line of force that diffuses to electronic product enclosure certain will cause vortex flow, thereby in this place's heating, make this place's temperature too high, damage casing.Traditional solution party's rule is to adopt the material of good heat dispersion performance, thereby has improved the cost of electronic product enclosure.
Summary of the invention
The purpose of the utility model is to provide a kind of magnetic line of force that transformer is produced to weaken the vortex flow to the casing place generation of electronic product, and has the novel high-frequency transformer of shield effectiveness.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of novel high-frequency transformer; It comprises skeleton, magnetic core, primary coil, secondary coil and upper shield; Said magnetic core is mounted on the skeleton, and said upper shield is used to cover primary coil and the secondary coil on the skeleton, it is characterized in that: said cover covers and is provided with screen.
Said screen is a metallic plate, and said cover covers and is provided with draw-in groove, and said screen is stuck in and overlaps on the draw-in groove that covers.
Said screen is a metallic plate, and said cover covers the positioning supports post is set, and said support column is provided with salient point, and said metallic plate is provided with the hole, and said metallic plate places and overlaps on the support column that covers, and adopts some glue to fix.
Said screen is inner for embedding upper shield, and said screen is metallic plate or metal powder layer.
Said metallic plate is an aluminium sheet.
The beneficial effect of the utility model is: because the screen of the utility model is a metallic plate; And placing cover to cover or be stuck in cover covers; Therefore metallic plate can produce shield effectiveness, weakens the magnetic line of force that transformer is dispersed into electronic product enclosure, thereby can in the casing of electronic product, not concentrate and produce somewhere big vortex flow; And make temperature too high, the infringement casing.
