Description

SMD LED transformer skeleton of antidetonation

Technical Field

The utility model relates to an electronic product, concretely relates to transformer of LED lamp.

Background

A transformer is a device for transforming ac voltage, current and impedance, and when an ac current flows through a primary winding, an ac magnetic flux is generated in an iron core (or a magnetic core), so that a voltage (or a current) is induced in a secondary winding. The transformer consists of a framework, an iron core (or a magnetic core) and a coil, wherein the iron core is arranged on the framework, the coil is provided with two or more than two windings, the winding connected with a power supply is called a primary coil, and the other windings are called secondary coils.

And the primary coil of the LED transformer is connected with a power supply, and the secondary coil of the LED transformer is connected with an LED lamp. The LED is widely applied to stations, vehicles and other public places, wherein the LED transformer is easily damaged by vibration in the vehicles or other application places which are easy to generate vibration.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problems that: provided is an LED transformer framework capable of resisting shock.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a SMD LED transformer skeleton of antidetonation, includes base and wire winding part, and the base includes a pair of support section, the thin plate of putting on a pair of support section of tie, and the wire winding part is vertical structure, sets up on the thin plate.

The core and the coil are the main parts of the weight of the transformer, the core is inserted on the winding part, the coil is wound on the winding part, the winding part carrying the core and the coil is positioned on the thin plate, the thin plate is supported by a pair of supporting parts, and the pair of supporting parts are supported on two sides of the thin plate. When the transformer is vibrated, the elastic deformation of the thin plate can absorb shock of the winding part, so that the shock-resistant effect of the transformer is achieved.

The utility model discloses utilize transformer skeleton texture's design, when the transformer received vibrations, through unsmooth elastic deformation about the sheet metal, carry out the shock attenuation to transformer principal weight part.
