Abstract

The utility model provides a transformer, which comprises a wire rack (1-1), pins (1-2), magnet cores (1-3) and coils. The transformer comprises the wire rack (1-1), the pins (1-2), the magnet cores (1-3) and the coils, wherein pins (1-2) are arranged on the wire rack (1-1), a storage space is arranged on the wire frame (1-1), the magnet core (1-3) is arranged in the storage space, side corners of the lower portion of the wire rack (1-1) are sunken, and the coils are wound on the wire rack (1-1). The side corners of the wire rack are sunken, when transformer is inserted on a matched circuit board, the side corners on the lower portion of the wire rack are lapped on the circuit board, and other parts on the lower portion of the wire rack can sink in the circuit board, thereby being capable of enabling the height of the transformer to have a bigger dropping space, and being capable of reducing whole height of equipment which are integrated with the transformer.

Description

A kind of transformer

Technical field

The utility model relates to field of electronic devices, relates in particular to a kind of transformer.

Background technology

Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and in electric equipment, transformer is commonly used for lifting voltage, matched impedance, safety isolation etc.

In prior art, transformer generally adopts non-blank coil holder, by pin straight cutting on circuit board.

From foregoing description, the coil holder of the non-breaking-out type of transformer adopting of the prior art, after being inserted on circuit board, coil holder lower limb is pasting circuit board, can not further reduce the height of transformer.

Utility model content

The utility model provides a kind of transformer, and after being inserted on circuit board, the height of transformer has larger decline space, the complete machine height of the equipment that can reduce transformer integrated.

The utility model provides a kind of transformer, and described transformer comprises: coil holder 1-1, pin 1-2, magnetic core 1-3, coil;

Described pin 1-2 is arranged on coil holder 1-1;

Described coil holder 1-1 has an accommodation space, and described magnetic core 1-3 is arranged in described accommodation space;

The corner depression of described coil holder 1-1 bottom;

Described coil winding is on coil holder 1-1.

Further, the bottom of described coil holder also comprises at least one boss.

Further, the mode coiling that described coil is multi cord by parallel winding of multiple coils forms.

A kind of transformer providing by the utility model, the corner depression of coil holder, in the time of on the circuit board that this transformer is inserted in to coupling, the corner of coil holder bottom rides on circuit board, other parts of coil holder bottom can sink to circuit board the inside, can make the height of transformer there is larger decline space, the complete machine height of the equipment that can reduce transformer integrated.
