Description
Technical field
The utility model relates to transformer coil manufacturing technology field, specifically one kind can guarantee transformer pressure resistance
Grade, the plate coil device for being used to form transformer coil improved production efficiency and product quality.
Background technique
It is well known that transformer is the device for converting alternating voltage, electric current and impedance, when being connected with alternating current in primary coil
When stream, iron core（Or magnetic core）In just generate exchange flux, make to induce voltage in secondary coil（Or electric current）.Transformer is by iron core
（Or magnetic core）Formed with coil, coil there are two or more than two windings, wherein connect the winding of power supply primary coil, remaining
Winding secondary coil.Transformer is a kind of utilization undesirable mutual electromagnetic inductance effect, voltage of transformation, the device of electric current and impedance.
The high frequency transformer that the manufacturer of traditional Switching Power Supply uses usually all is to use enameled wire coiling high-voltage winding,
The coiling low pressure winding outside high-voltage winding again.Since winding operation is manually completed in production process, lead to homogeneity of product
Difference, EMI, EMC characteristic are bad and production efficiency is low.
In order to improve the production efficiency and EMI the and EMC performance of raising transformer, the existing producer pass through PCB and print electricity
Two groups of coils and iron core and other accessories on pcb board, are then carried out coil circuit structure setting by road plate manufacture craft
Assembling obtains transformer.The main problem of this method is that the electric current that pcb board coil can bear is smaller, is unable to satisfy height
The work requirements of primary coil in frequency power transformer.
Summary of the invention
The utility model is directed to shortcoming and defect existing in the prior art, proposes a kind of structurally reasonable, production efficiency
High, reliable product quality the plate coil device for being used to form transformer coil.
The utility model can be achieved by the following measures：
A kind of plate coil device being used to form transformer coil, it is characterised in that the plate obtained equipped with stamped processing
There are at least two circles to be in conplane coil circle body, be equipped with connection between adjacent coil circle body for shape coil, plate coil
Bridge.
Two free ends of plate coil described in the utility model are respectively equipped with connecting terminal, and two free ends are respectively led into
Outside coil main body, further, free end and plate coil main body on the outside of coil are in same plane, are located in coil
The free end of side is drawn along the upside of coil main body or downside, level range locating for lead pitch coil main body be 0.01 to
1.0mm。
Plate coil winding described in the utility model is annular, and plate coil center is equipped with for the hollow of iron core to be arranged
Portion.
Connecting bridge described in the utility model is an integral structure with coil circle body, and stamped processing obtains, connecting bridge
Width range is 0.01mm to 1.0mm, and for the ease of subsequent processing, connecting bridge is equipped with v-notch.
More than two connecting bridges are equipped between adjacent coil circle body described in the utility model.
The utility model during use, according to the power requirement of transformer, is filled by setting the plate coil
The coil thickness and width set obtain the coil that can carry high current, then carry out the plate coil device at injection molding
Reason, due to being equipped with connecting bridge structure between adjacent coil circle body, can effectively avoid adjacent line in injection process technique
Circle circle body is staggered, and then can guarantee that coil main body can be by abundant insulation processing, to guarantee product in Shooting Technique
Stress levels meet the requirements, and can be removed by notch before Shooting Technique terminates since the connecting bridge is equipped with notch
Connecting bridge obtains complete transformer coil；Have the component of reliable pressure-resistant performance through subsequent group by what Shooting Technique obtained
It can be obtained power transformer product after dress.
The utility model compared with prior art, can effectively improve the pressure-resistant performance EMI of production efficiency and product
And EMC performance, have the advantages that structurally reasonable, easy to operate significant.
