Abstract

The utility model provides a transformer. The transformer comprises a transformer body, first copper foil, second copper foil and grounded wires, wherein the transformer body is wrapped by the first copper foil in the magnetic core direction of the transformer body and wrapped by the second copper foil in the coil direction of the transformer body, and the first copper foil and the second oil are connected with a grounded pin through the grounded wires. According to the transformer, the two pieces of copper foil is wound on the transformer body in the magnetic core direction and the coil direction respectively, the transformer is wrapped in the different directions, the wrapping area of the transformer body by the copper foil is increased, and anti-radiation strength can be improved.

Description

A kind of transformer

Technical field

The utility model relates to electronic device, 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, for transformer anti-electromagnetic-radiation is disturbed, general employing in the peripheral coiling of transformer region is wound around one deck Copper Foil along coil direction, to weaken the impact of electromagnetic radiation.

From foregoing description, in prior art, transformer body is wound around along coil direction, along magnetic core direction, be not wound around, radiation proof intensity is less.

Utility model content

The utility model provides a kind of transformer, respectively transformer body is wound around along magnetic core direction and coil direction with two blocks of Copper Foils, can improve radiation proof intensity.

The utility model provides a kind of transformer, and described transformer comprises:

Transformer body, the first Copper Foil, the second Copper Foil, earth lead;

Described the first Copper Foil wraps in transformer body along the magnetic core direction of transformer body;

Described the second Copper Foil wraps in transformer body along the coil direction of transformer body;

Described the first Copper Foil is connected with grounding pin by earth lead with the second Copper Foil.

Further, the joint of the first Copper Foil is by being welded and fixed.

Further, the joint of the second Copper Foil is by being welded and fixed.

Further, the joint of described the first Copper Foil and the second Copper Foil is in same side;

The joint of the first Copper Foil and the second Copper Foil is all fixed by the first solder joint.

Further, described the first Copper Foil is connected with grounding pin by earth lead with the second Copper Foil, comprising: one end of described earth lead is connected with described the first solder joint, and the other end is connected with grounding pin.

Further, described the first Copper Foil becomes right-angled intersection to be connected with the second Copper Foil.

A kind of transformer providing by the utility model, respectively transformer body is wound around along the magnetic core direction of transformer body and the coil direction of transformer body with two blocks of Copper Foils, along different directions, transformer is coated, the coated area of Copper Foil to transformer body can be increased, radiation proof intensity can be improved.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of a kind of transformer of providing of the utility model embodiment.

Embodiment

For making object, technical scheme and the advantage of the utility model embodiment clearer; below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is the utility model part embodiment; rather than whole embodiment; based on the embodiment in the utility model; the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.

The utility model embodiment provides a kind of transformer, and referring to Fig. 1, this transformer specifically comprises:

Transformer body 101, the first Copper Foil 102, the second Copper Foil 103, earth lead 104;

The first Copper Foil 102 wraps in transformer body 101 along the magnetic core direction of transformer body 101;

The second Copper Foil 103 wraps in transformer body 101 along the coil direction of transformer body 101;

The first Copper Foil 102 is connected with grounding pin by earth lead 104 with the second Copper Foil 103.

Wherein, transformer body comprises: magnetic core 1011, coil 1012, grounding pin 1013.

In order to reduce costs, the joint of the first Copper Foil is by being welded and fixed, and the joint of the second Copper Foil is by being welded and fixed.

In addition, the first Copper Foil and the second Copper Foil also can be fixed by fixation adhesive tape etc.

The joint of the first Copper Foil and the second Copper Foil is all fixed by the first solder joint.The joint of the first Copper Foil and the second Copper Foil is in same side; The joint of the first Copper Foil and the second Copper Foil is all fixing by the first solder joint 105.

One end of earth lead 104 is connected with the first solder joint 105, and the other end is connected with grounding pin 1013.

The first Copper Foil becomes right-angled intersection to be connected with the second Copper Foil.

From the description of above-described embodiment, a kind of transformer that the utility model embodiment provides has following beneficial effect:

1, a kind of transformer providing by the utility model embodiment, respectively transformer body is wound around along magnetic core direction and coil direction with two blocks of Copper Foils, along different directions, transformer is coated, increase the coated area of Copper Foil to transformer body, can improve radiation proof intensity.

2, a kind of transformer providing by the utility model embodiment, with welding method Copper Foil is fixed, can be cost-saving.
