Description

A kind of radio-frequency rector iron core

Technical field

The utility model belongs to technical field of electric equipment more particularly to a kind of iron core of reactor.

Background technique

Inductor is also known as inductance coil, is one of the primary element for forming electronic circuit otherwise referred to as or choke, In a series of its extensive field for being used in such as signal processing, noise filtering, power generation, electrical transmission system etc.Electrical equipment Noise be always cannot be neglected technical indicator, reactor is no exception, especially iron core reactor.What reactor generated makes an uproar Sound is changed the stress for causing to attract or magnetostriction generates mainly due to stacking silicon steel sheet and air gap plate by magnetic flux in magnetic circuit, and It generates vibration or mutually collision causes.

Utility model content

Problem makes improvements the utility model in view of the prior art, i.e., the technical problem to be solved is that mention for utility model For a kind of radio-frequency rector iron core of low-vibration noise.

The technical solution of the utility model are as follows: a kind of radio-frequency rector iron core, including iron yoke and iron core column, feature exist In the iron yoke and iron core column end interconnected are inclined-plane corner structure, and every piece of iron core column is by along its magnetic circuit The sub- iron core of muti-piece on direction mutually bonds, and air gap pad is equipped between adjacent sub- iron core, which includes The fixing belt of its outer surface is wound in along the circumferential direction of its magnetic circuit.

Further, the angle of chamfer of the inclined-plane corner structure of the iron yoke and the iron core column end is 45 degree.

Further, every piece of iron core column includes positioned at two pieces of sections of its end sub- iron core triangular in shape and being located at it The sub- iron core that the section at middle part is rectangle.

Further, the fixing belt is elastic band.

Further, the peripheral surface of the radio-frequency rector iron core is equipped with cricoid for fixing the groove knot of the fixing belt Structure.

Further, the fixing belt is stainless steel band.

Radio-frequency rector iron core using the above structure, by the way that the angle of chamfer and periphery winding is arranged admittedly in iron yoke and iron core column Determine the mode that band combines, can effectively reduce the vibration of iron yoke and iron core column junction from structure.In addition, for every block of iron Stem, sub- iron core and air gap pad are bonded using glue, equally effectively eliminate every piece of iron core column because magnetic hysteresis stretch principle generate Vibration and noise.

Fig. 2 is the three dimensional structure diagram of radio-frequency rector iron core provided by utility model embodiment.

Specific embodiment

It is described below for disclosing the utility model so that those skilled in the art can be realized the utility model.It retouches below Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.

Radio-frequency rector iron core provided by the utility model is in square shape comprising is located at a pair of of iron yoke of top and the bottom 1, it is located at left and right part a pair of iron core column 2 and fixing belt 3.

For every piece of iron yoke 1, two ends connecting with column iron core are inclined-plane corner structure, i.e., iron yoke is in radio-frequency rector Being projected as in iron circuit plane is trapezoidal.Similarly, for every piece of iron core column 2, two ends connecting with iron yoke 1 are also The inclined-plane corner structure that inclined-plane matches with the iron yoke angle.Connection glue is coated on the inclined-plane of inclined-plane corner structure.Preferably, all inclined-planes The angle of chamfer of corner structure is 45 degree.Using the above structure, it is directly vertically connected compared to traditional iron yoke and iron core column end Scheme, can effectively reduce the vibration of 2 junction of iron yoke 1 and iron core column from structure, to reduce noise.

Every piece of iron core column 2 is bonded by the sub- iron core 4 of muti-piece on its magnetic circuit direction, is equipped between adjacent sub- iron core 4 Air gap pad 5, and the air gap pads the glue that 5 two sides are coated with connexon iron core 4.Preferably, every piece of column iron core 2 is by being located at its end Two pieces of (projection in radio-frequency rector magnetic circuit plane) section sub- iron cores triangular in shape and be located therein (in high-frequency electrical Projection in anti-device magnetic circuit plane) the sub- iron core that is rectangle of section bonds.Sub- iron core 4 and air gap are bonded using glue Pad 5, can effectively eliminate every piece of iron core column 2 because magnetic hysteresis stretch principle generation vibration and noise.

Fixing belt 5 is wound in the outer surface of radio-frequency rector iron core along the circumferential direction of radio-frequency rector iron circuit.High-frequency electrical The peripheral surface of anti-device iron core is equipped with cricoid for fixing the groove (not shown) of the fixing belt.Fixing belt 5 can be selected Stainless steel band.In the present embodiment, the preferred elastic band of fixing belt 5 selects the purpose of elastic band to be to shake in radio-frequency rector iron core When dynamic, tensile force can be provided between adjacent sub- iron core and between iron yoke and iron core in real time, to be further reduced vibration Noise.In addition, using the aging of connection glue and air gap pad 5 as radio-frequency rector iron core uses the increase of time, making It obtains between adjacent sub- iron core and adhesive strength reduces between iron yoke and iron core, the setting of elastic band also ensures that adjacent sub- iron core Between and iron yoke and iron core between be reliably connected.Being provided in for groove prevents fixing belt 5 from generating in the front-back direction because of vibration Displacement, so that it be avoided to fall off.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model Kind changes and improvements, these changes and improvements are both fallen in the range of claimed invention.The guarantor of the utility model Shield range is defined by appended claims and its equivalent.
