Stitch electric reactor and method for manufacturing same

Abstract

The invention relates to a stitch electric reactor and a method for manufacturing the same. The stitch electric reactor comprises an iron core, an insulating framework, a coil winding, an insulating protective layer and an insulating bottom plate. Openings are formed in two ends of the hollow insulating framework, and the insulating framework fixedly sleeves the periphery of the iron core; the coil winding comprises a conducting wire, an insulating layer is arranged on the outer surface of the conducting wire, the conducting wire is fixedly wound on the periphery of the insulating framework, and two ends of the conducting wire extend out of the lower surface of the insulating framework; the insulating protective layer covers the periphery of the coil winding; the insulating bottom plate is fixed to the lower end of the iron core, and via holes for the two ends of the conducting wire are formed in the insulating bottom plate; the two ends of the conducting wire penetrate the via holes, stitches are formed by portions, which are positioned at the lower end of the insulating bottom plate, of the conducting wire, and the peripheries of the stitches are free of insulating layers; the stitches are used for being connected with other electronic elements. The stitch electric reactor and the method have the advantages that the stitch electric reactor is low in production cost and simple in production process.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a stitch reactor and a preparation method of the stitch reactor. Background technique [0002] A reactor is a conductor that generates a magnetic field in a certain space it occupies when it is energized. It is used to limit the current impact caused by sudden changes in grid voltage and operating overvoltage, smooth the peak pulse contained in the power supply voltage, or smooth bridge rectification The voltage defect generated when the circuit commutates effectively protects the frequency converter and improves the power factor. It can prevent the interference from the power grid and reduce the "pollution" of the power grid caused by the high-order harmonics generated by the rectification part of the frequency converter, effectively preventing interference with other equipment. It can also be used on the DC side of the converter. [0003] Existing reactors gener...

Problems solved by technology

Therefore, there are many parts in the existing reactor, and the connecting wires usually need to be fixed additionally; so the production cost of the existing reactor is high and the production process is cumbersome.
