Method used

According to the specific embodiment provided by the invention, the present invention discloses the following technical effects: high-current inductance of the present invention, magnetic ring is formed by the butt joint of two semicircular magnetic rings, the inductance coil is sleeved on the magnetic ring group, and the inductance The coil is wound by a winding machine, which realizes separate winding of the coil and separate processing of the magnetic ring. Through the cooperation of the structure of the coil and the magnetic ring, the rapid processing and assembly of the inductor is realized, and the processing speed of the inductor is improved. And the inductance coil of the present invention only needs to be sleeved on the magnetic ring group to realize the assembly of the magnetic ring group and the inductance coil, avoiding the direct winding of the coil on the magnetic ring, and greatly shortening the assembly time of the coil and the magnetic ring. The invention can directly change the size of the magnetic ring group by increasing or reducing the number of magnetic rings, and can meet th...

Abstract

A large current inductance is disclosed. The high current inductor comprises a magnetic ring group, an inductance coil and a fixed base support; The induct coil is formed by winding the enameled flatcopper wire by a winding machine, the inductance coil is sleeved on the magnetic ring group, and the two ends of the inductance coil are inserted into the fixed bottom support; A magnetic group is formed by sequentially arranging at least one magnetic ring along an axial direction; Each magnetic ring comprises two semicircular magnetic rings, one semicircular magnetic ring having grooves at both ends and the other semicircular magnetic ring having projections at both ends; The protrusion matches the groove for butting the two semicircular magnetic rings into a magnetic ring. The large currentinductor of the invention is convenient for processing and batch production, and can improve the processing speed.

[0034] See Figure 1 to Figure 6 The high-current inductor includes a magnetic ring group 1, an inductance coil 2 and a fixed base 3, and the magnetic ring group 1 only includes a magnetic ring 4.

[0035] The inductance coil 2 is made by winding a varnished rectangular copper wire with a winding machine, the inductance coil 2 is sleeved on the magnetic ring assembly 1, and both ends of the inductance coil 2 are inserted into the fixed base 3 Inside;

[0036] Each of the magnetic rings 4 includes two semicircular magnetic rings 5 and 6, one of the semicircular magnetic rings 5 is provided with grooves 7 at both ends, and the other semicircular magnetic ring 6 has protrusions 8 at both ends; the protrusions 8 matches the groove 7 and is used to connect two semicircular magnetic rings 5 and 6 to form the magnetic ring 4.

[0037] The magnetic ring 4 of the present invention is circular. The two semicircular magnetic rings 5 and 6 can be formed at one time through customized molds, which can reduce the trouble of secondary processing while meeting the requirements of conventional mass production, and solve the problem of low accuracy of magnetic ring butt bonding and positioning.

[0038] The two ends of the inductance coil 2 are welded to the fixed base 3. Two slots 9 are provided on the fixed bottom bracket 3. Each end of the inductance coil 2 extends downward from a terminal, and the two terminals are respectively inserted into the slots 9 of the fixed base 3.

[0039] The joints of the two semicircular magnetic rings 5 and 6 are fixed with epoxy glue.

[0040] The material of the fixed bottom bracket 3 is a high temperature resistant and flame retardant insulating material.

[0041] The bottom of the fixed base 3 is provided with PCB board welding pins 10 for welding the fixed base 3 on the PCB board.

[0042] The shape of the inner ring of the inductance coil 2 matches the shape of the magnetic ring group 1, so that the inductance coil is just sleeved on the magnetic ring group 1.

[0043] The custom-made winding machine can wind the lacquered rectangular copper wire into the inductor coil 2 with the required wire diameter and cross-sectional area, and at the same time, the length of the terminal, the width of the coil, the length of the coil, and the number of turns can meet the preset requirements Claim.

[0044] The cross-sectional shape of each magnetic ring 4 is rectangular.

[0045] The high-current inductor of the present invention realizes the rapid installation and finalization of the product through the cooperation of the flame-retardant and high-temperature resistant insulating base. The assembly process is as follows: firstly, the two semicircular magnetic rings 6 are respectively sleeved in the wound inductor coil 2, and then the inductor The terminal of the coil 2 is inserted into the fixed base 3, and then epoxy glue is used to fix the butt joint of the two semicircular magnetic rings 5 and 6 to form a circular magnetic ring 4.

[0048] The difference between the second embodiment and the first embodiment is that the magnetic ring group 1 includes four magnetic rings 4. The four magnetic rings 4 are arranged in sequence along the axial direction. As the number of magnetic rings 4 increases, the size of the corresponding inductance coil 2 also increases to match the magnetic ring group 1. By adjusting the number of magnetic rings 4, the magnetic rings can meet different current inductances.
