Description
Technical field
Switching power circuit plate application field is the utility model is related to, is controlled more particularly to a kind of orientable magnetic core installation
Tool.
Background technology
In recent years, as the fast development of power electronics industry, people increasingly pay attention to production efficiency, test stone
The leading position of design management and control is progressively occupied, wherein module height standardization is exactly a ring crucial in quality management and control
Section.If module, during magnetic core is installed, human error causes magnetic core installation crooked so as to which inductance value deviation is bigger, can
It can cause module operation irregularity or even damage other components of client, the massive losses being so bound to cause on manpower and cost.
Usually in board design, guarantee magnetic core inductance value stabilization is ideally needed to have in certain value too big
Deviation, due to manual operation or mismachining tolerance, can be likely to cause inductance value tolerance big in practical operation.In order to prevent because
The reason for installation, causes tolerance big, it is necessary to examine whether the magnetic core position of the module after assembling flushes with gauge.
It is illustrated in fig. 1 shown below, is the gauge of traditional installation magnetic core, as seen from the figure, four angles of gauge are positioned with baffle
The circuit board of jigsaw, this way do not have any positioning magnetic since the presence positioning of error is not very accurate on gauge
The component of core, magnetic core are easy to shift due to controlling bad in high-volume operation, cause the inductance value of magnetic core to deviate and set
Definite value.
In view of the above-mentioned problems, the utility model proposes a kind of orientable magnetic core assembling fixture, gauge can accurately be determined
Position circuit board, and precisely limit the installation site of magnetic core.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of orientable magnetic core assembling fixture.
Technical solution is used by the utility model solves above-mentioned technical problem：The gauge includes a bakelite plate, if
Dry groove, antistatic rubber skin, magnetic core positive stop strip, positioning pin, foot pad, it is characterised in that the gauge utilizes magnetic core positive stop strip
Magnetic core is spacing, prevent that magnetic core is crooked to one side during installation.
Preferably, above-mentioned orientable magnetic core assembling fixture, it is characterised in that the jigsaw circuit board of magnetic core to be installed is placed
On gauge, with positioning finger setting, prevent from rocking, at the same it is also more precisely reliable.
Preferably, above-mentioned orientable magnetic core assembling fixture, it is characterised in that be laid with antistatic in the region of installation magnetic core
Rubber, prevents electrostatic from causing to damage to electronic device.
Preferably, above-mentioned orientable magnetic core assembling fixture, it is characterised in that groove is set according to the size of power module
Meter, for avoiding the PIN needle of module, allows the bottom magnetic core of power module to be attached to antistatic rubber skin.
The utility model provides a kind of magnetic core localization tool simple in structure, improves the standard of product installation operation
Change, contribution is made that to improve the uniformity of new technology electronic product.
Brief description of the drawings
Fig. 1 is traditional magnetic core assembling fixture structure diagram.
Fig. 2 is the overall structure diagram of orientable magnetic core assembling fixture.
Embodiment
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
It is illustrated in fig. 2 shown below, which includes a bakelite plate 4, several grooves 5, antistatic rubber skin 3, magnetic core is spacing
Bar 2, positioning pin 1, foot pad 6.The jigsaw circuit board of magnetic core to be installed prevents from rocking, positioning pin ratio gear using positioning finger setting
Plate is more precisely reliable；Groove is designed according to the size of power module, for avoiding the PIN needle of module, makes the bottom of power module
Portion's magnetic core can be attached on antistatic rubber skin, and magnetic core is installed on antistatic rubber, can prevent electrostatic from being made to electronic device
Into damage；The jigsaw circuit board of magnetic core to be installed is placed on gauge, magnetic core positive stop strip needs the position that limits in magnetic core,
During magnetic core is installed, ensure that magnetic core is not crooked to one side.
Although the foregoing describing the specific implementation case of the utility model, it will be appreciated by those of skill in the art that
These are merely illustrative of, and on the premise of the principle and essence without departing substantially from the utility model, these case study on implementation can be done
Go out various changes or modifications.Therefore, the scope of protection of the utility model is defined by the appended claims.
