- This invention relates to the manufacturing method of the laminated coil which has the 1st coil part and the 2nd coil part which rounded off the rectangular conducting wire.
- the reactor generally has a winding and a magnetic core, and is formed by winding a coil around the magnetic core to form an inductance.
- reactors are used in boost circuits, inverter circuits, active filter circuits, and the like.
- two coils are connected in parallel so that current directions flowing through the coils are in a positive direction.
- each of the 1st coil part and the 2nd coil part was manufactured, and it connected by the method of soldering etc., respectively.
- Such a manufacturing method requires two kinds of coil parts and requires a connection process by soldering or the like, an insulation treatment process of the connection part, an electrical property inspection process of the associated connection part, an electrical insulation property inspection process, and the like.
- Increase in production, and at the same time result in an increase in cost, and also the product produced by the above manufacturing method has a connection part to which it is connected, and furthermore, since the connection part is located outside of the coil, reliability is also low and There were disadvantages in terms of performance, such as deviations are likely to occur.
- the first coil part and the second coil part are continuously formed so that a connection process such as soldering is unnecessary, but a method of forming a twisted connection part by folding the second coil part by 180 ° with respect to the first coil part is performed. There is a problem in that stress concentration occurs in the torsion-formed connection manufactured by this method.
- this coil forming method includes a length measuring step of measuring the length of the connecting portion while forming the first coil before forming the second coil and at the same time after the first coil is completed but before the second coil is completed. And a length distribution process for allocating the measured lengths of the connecting portions for the predetermined spacing of the two coils and for adjusting the flat conductors set in the second coils, and correspondingly to the divided length dimensions.
- the present invention solves the problems of the prior art described above, and at the time of coil manufacture, it can be continuously manufactured with one flat lead, so that the manufacturing process of the coil can be simplified as compared with the above-described conventional manufacturing method, It is an object of the present invention to provide a method of manufacturing a laminated coil that can reduce costs during manufacturing, improve product reliability, and further ensure a certain performance.
- the present invention comprises the steps of: forming a first coil portion stacked on each cylinder by winding one flat lead at a starting point spaced apart from one first end thereof;
- connection part Forming a connection part in a stacking direction by bending the flat wire of the coil part
- first coil portion and the second coil portion is provided with a laminated coil manufacturing method comprising the step of unfolding the connecting portion bent in parallel in parallel in the same direction, in the same plane.
- the forming of the connecting portion provides a method of manufacturing a laminated coil, wherein the first bending portion of the connecting portion is bent in a direction orthogonal to the longitudinal direction of the flat conductive line.
- the forming of the connecting portion may be a step of bending the flat lead in a direction perpendicular to the longitudinal direction so as to coincide with the stacking direction of the flat lead in the first bent portion of the connecting portion. It provides a laminated coil manufacturing method characterized in that the step of bending the second bent again.
- the first coil part and the second coil part are continuously manufactured, so that an additional connection process such as soldering to the connection part of the first coil part and the second coil part is unnecessary, and in the coil process step By adding the process of bending the connection, the connection is finally placed on the same plane without twisting, and the number of manufacturing processes is greatly reduced as the step of measuring the remaining wire length of the connection in the coil processing step becomes unnecessary.
