Abstract

The utility model discloses a transformer with irregularly-shaped coil, which is characterized by comprising the coil and a magnet core, wherein the coil is a hollow cuboid; the cuboid is wound with a primary coil; L-shaped brackets are arranged on both sides of the coil; one of the two L-shaped brackets is narrower than the coil and is wound with a secondary coil; the secondary coil terminal passes through the inside of the bracket to be connected to a PIN foot of the side thereof; the other one of the two L-shaped brackets is wider than the coil; the primary coil terminal passes through the inner part of the bracket to be connected to a PIN foot of the side thereof; the magnet core is divided into two parts; each part has an E shape and the middle part is thicker; and part of the middle part of the magnet core is inserted into the coil. The transformer with the irregularly-shaped coil has the characteristics of small volume, light weight, low loss, low noise, high efficiency and energy conservation, and is particularly suitable to be used in an LCD display or a notebook computer.

Description

A kind of transformer of irregularly shaped line bag

Technical field:

The utility model relates to electronic circuit accessory field, is a kind of transformer of irregularly shaped line bag specifically.

Background technology:

Transformer is the element that often uses in the circuit, and the function in circuit mainly contains: voltage transformation, impedance conversion, isolate, voltage stabilizing or the like, but according to different purposes, its size and profile are all different, and the magnetic core material of employing and enamelled wire etc. also are different.In the circuit of electronic product, weight and space also are important consideration, so power transformer and not being suitable in the electronic circuit, especially in LCD display, and the transformer that uses in the notebook computer, strict especially.

Summary of the invention:

Be to solve the problem that prior art exists, a kind of transformer of irregularly shaped line bag is provided, have that volume is little, in light weight, a low-loss, low noise, energy-efficient characteristics.

The technical solution adopted in the utility model:

A kind of transformer of irregularly shaped line bag, it is characterized in that: have line bag and magnetic core, the line bag is hollow cuboid, cuboid is wound with primary coil outward, there is L type carriage line bag both sides, two one of them width of L type carriage twine secondary coil less than line bag and outside, and another width is greater than the line bag, and primary coil terminal, secondary coil terminal pass the PIN pin that carriage is connected internally to its side respectively; Magnetic core is divided into two parts, and each part is the E type, and mid portion is thicker, and a part is inserted in the line bag in the middle of the magnetic core.

Advantage of the present utility model:

The transformer of a kind of irregularly shaped line bag that the utility model provides has that volume is little, in light weight, a low-loss, low noise, and energy-efficient characteristics are particularly useful for LCD display, in the notebook computer.
