In winding type coil component of the invention, the initial part of more wire rods is connected to the electricity of one end side flange portion Pole, and be bent in the core lateral edge portion of the electrode and extend to winding start position.In particular, being connected to away from core The initial part of wire rod of electrode of the farther away one end side flange portion of winding start position there is connection interconnecting piece on the electrode The wiring portion for being transversely bent with the core lateral edge portion in electrode and extending to winding start position.It therefore, can be true It protects at a distance from the initial part and the electrode that current potential is different of the wire rod, so as to reduce the risk for generating short circuit.The wire rod of one side End portion after the electrode for being connected to another side flange part, be bent in the core lateral edge portion of electrode and to winding End position extends.The end portion of the wire rod of another party is then only connected to the winding farther away electrode of end position away from core The end portion of wire rod is with the interconnecting piece connected on the electrode and in the core lateral edge portion of electrode or than the core side Edge part more lean on the position of core side be transversely bent and to winding end position extend wiring portion.That is, from core Winding end position be drawn out, and be bent near the edge part of the core side of electrode to transverse direction, therefore can ensure At a distance from the wiring portion electrode different with current potential, so as to reduce the risk that short circuit is contacted and generated with the electrode.In addition, Due to being not necessarily to be pressed by line pressing component relative to core as previous, so the damage of wire rod can be prevented. In addition, only being deposited during until being drawn out from the winding end position of core and being connected to electrode in the end portion of wire rod Bending part at 1 position, therefore wire rod is difficult to generate loosening.
In the present specification, the position of " winding start position " core that be the wire rod that is wound initially contact with core Set the position or side of perhaps side " winding end position " core that be the wire rod that is wound finally contact with core Face.It is connected to the initial part and connection of the wire rod of the electrode of the farther away one end side flange portion of winding start position away from core Connection is respectively provided in the end portion of the wire rod of the electrode of the farther away another side flange part of winding end position away from core Portion and wiring portion.Interconnecting piece is the part connected on the electrode, and wiring portion is the winding start position in interconnecting piece and core The part extended between (or winding end position).It is connected to the closer one end side flange of winding start position away from core The initial part of the wire rod of the electrode in portion and the electricity for being connected to the farther away one end side flange portion of winding start position away from core The initial part of the wire rod of pole can along iron core axis direction connect on the electrode, be connected to the winding end position away from core compared with The end portion of the wire rod of the electrode of close another side flange part can also connect on the electrode along iron core axis direction.Another party Face, the end portion for being connected to the wire rod of the electrode of the winding farther away another side flange part of end position away from core can also be with It is connected on the electrode along relative to the inclined direction of iron core axis direction." relative to the inclined direction of iron core axis direction " be with " iron core axis direction " is compared to the biggish direction of tilt angle relative to iron core axis.In addition, " transversely bend " refer to from It is observed with the opposed direction of electrode, the initial part (or end portion) of wire rod generates angle change between wiring portion and interconnecting piece Change.The reasons why initial part of wire rod is transversely bent is because the initial part of wire rod is being connected to one end along iron core axis direction After the electrode of side flange portion, the initial part of the wire rod is guided to the winding start position of core.On the other hand, the end of wire rod The reasons why stop is transversely bent is because in the line for making to be drawn out from the winding end position of core by wire rod hooking part After the end portion bending of material, the end portion of the wire rod is connected to the electrode of another side flange part.
Herein, method of winding of the invention is illustrated in case where 2 wire rods are wound in iron core.Firstly, One end side flange portion of iron core is kept by rotating mechanisms such as main shaft chucks.Next, the top portion of 2 wire rods is hooked in hook Shape pin etc. extracts 2 wire rods out from nozzle, and moves inward nozzle on the outside of the side flange portion of one end, thus by two lines The initial part of material is connected in the configuration of iron core the axis direction at one end electrode of side flange portion, and through engagement unit respectively It connects.The initial part of 2 wire rods is connected on the electrode along iron core axis direction as a result,.In the present specification, " iron core axis side To " without strictly parallel with iron core axis direction, as long as so that the interior lateral margin (core side) of major general's electrode is (convex with lateral border Surface side on the outside of edge) between the mode that connects extend.In this way, the initial part of wire rod is connected to electricity along iron core axis direction Pole, therefore the short circuit of the initial part that the is able to suppress wire rod electrode different from current potential.The initial part of wire rod is being connected to electrode Afterwards, 2 wire rods are axial to transverse guidance relative to iron core, rotate iron core by rotating mechanism, thus together by 2 wire rods It is wound in core.
After winding steps, by the groove portion of wire rod hooking part insertion another side flange part, and by the end of 2 wire rods Stop is guided from the Inside To Outside of another side flange part.The wire rod of one side does not contact with wire rod hooking part and only to flange part Outside is guided, so as to fixed on the electrode along iron core axis direction.The end portion of the wire rod of another party is hooked on line The front end of material hooking part, and bend the wire rod.The bending is different from the line pressing component in existing winding arrangement, due to Only wire rod is transversely bent, so can reduce the load applied to wire rod, so as to inhibit damage, broken string.By line After material bending, the tension of the end portion is kept to be permanently attached in corresponding electrode.In this case, the end for the wire rod being bent Stop is connected and fixed on electrode along relative to the inclination of iron core axis direction or parallel direction.Herein, in core and electrode Between the wire rod that sets up way by wire rod hooking part generates angle change wherein, therefore can ensure the wire rod and current potential not The distance of same electrode, so as to inhibit short circuit.In this way, completing coil component.
As in the present embodiment, in the feelings to be formed with the iron core of the multiple electrodes with groove portion therebetween in each flange part Under condition (in other words, there are multiple foots in each flange part, in the mounting surface situation with electrode of foot), line is inserted into groove portion Material hooking part is until core is more leaned on to the medial surface of another side flange part or than the medial surface in the front end of the wire rod hooking part Until the state outstanding of portion side, so as to bend the end portion of wire rod easily by the front end of wire rod hooking part.Especially It is, in the case where keeping the front end of hooking part more prominent to core side than the medial surface of another side flange part, to be easy line Material is hooked in the front end of wire rod hooking part, so that the crooked place of wire rod is stablized, and it is different from current potential to expand the wire rod Electrode distance.
The direction of insertion of wire rod hooking part is arbitrary, such as is considered on the outside of iron core axis direction towards groove portion along level side Method to insertion, method of the insertion of the top from iron core etc..In the axial direction for making wire rod hooking part and iron core, front and back is moved in parallel In the case where dynamic, i.e., in the case where being inserted into the horizontal direction on the outside of iron core axis direction towards groove portion, it is able to suppress to wire rod The interference of the nozzle and wire rod hooking part that guide, and pressing force is not applied to iron core, therefore can reduce to iron core Load.
For three line common mode choke coils, end portions in 3 wire rods, 2 or 1 wire rods and current potential Different electrodes is close, so that the risk for generating short circuit increases compared with the common mode choke coil of two wires.It is for example answered by the present invention In the case where for three line common mode choke coils, two strand of front end of wire rod hooking part can also be made, in respective front end Portion hooks 2 wire rods respectively and makes its bending.That is, can also be formed as constructing as follows: in the one end and the other end of iron core The flange part of side is respectively formed with 3 electrodes, and the position of flange part between these electrodes is respectively formed with 2 groove portions, Wire rod hooking part is provided with 2 protrusions for being inserted into 2 groove portions of another side flange part respectively.In this case, it can be ensured that 2 At a distance from the electrode different with current potential of the end portion of root wire rod, so as to reduce the risk for generating short circuit.
In addition, can also be formed as being provided in wire rod hooking part and only insert for three line common mode choke coils Enter 1 protrusion of the groove portion of in 2 groove portions of another side flange part, away from core winding end position remote position Construction.In this case, it can only be hooked in wire rod hooking part and be connected to the farthest position of the end position of the winding away from core The wire rod for the electrode set simultaneously bends it transversely.In addition, the end portion for being connected to the wire rod of the electrode in center is not transversely curved Folding ground (with not being hooked in wire rod hooking part) is connected to the electrode in center.Therefore, with the as described above termination for hooking 2 wire rods The case where portion, is compared, and can simplify the movement of the nozzle of extraction wire rod, so as to shorten the activity duration.
Iron core can also be formed as having not between the side or flange part and core of the core side of flange part There is the construction of the isolation part of electrode.Herein, isolation part be for core and electrode be spaced apart iron mandrel's line direction between Every not electrode part.It, can be different from current potential by wire rod in the case where iron core is formed with such isolation part The distance of electrode expands amount corresponding with isolation part size, therefore has to be further reduced and generate the excellent of short-circuit risk Point.Isolation part can be set in the side of the core side of flange part, also can be set between flange part and core.Three In line common mode choke coil, in the electricity that the end portion of the wire rod in center is not connected to bendingly transversely to center as described above In the case where pole, the end portion of the wire rod and adjacent electrode (current potential different electrode) are close, generate short circuit to exist A possibility that risk increases.In this case, as long as in advance between the core side of flange part or flange part and core Formed isolation part, just can be ensured by the isolation part center wire rod end portion at a distance from adjacent electrode, so as to The bending operation of wire rod is enough omitted, and inhibits short circuit.
The present invention is other than being applied to two wires common mode choke coil, three line common mode choke coils, additionally it is possible to similarly answer For four line common mode choke coils, using pulse transformer type coil of 4 wire rods etc., used the multi-thread winding of more wire rods Molded line coil component.
In the present invention, rotating mechanism is also configured to one end side flange portion of clamping iron core and makes its rotation, wire rod Hooking part and its movement device are formed as the structure for being set to the fixed part different from rotating mechanism.In the method for rotating iron core In there are cantilever support modes and both arms support pattern, but do not need in cantilever support mode clamping another side flange part, Without being directed at axle center, therefore driving mechanism can be simplified.In this case, by setting wire rod hooking part of the invention It is placed in the fixed part different from rotating mechanism, as long as to only make the movement of wire rod hooking part at the end portion of connection wire i.e. Can, so as to mitigate the burden applied to iron core, and inhibit short circuit.
As described above, according to the present invention involved in method of winding and winding arrangement, by the termination of at least 1 wire rod Portion is hooked in wire rod hooking part and bends it transversely, press etc. applying to wire rod like that rather than existing winding arrangement Application of load, therefore can reduce and damaged to wire rod bring, so as to inhibit damage, broken string.After bending wire rod, by it End portion is connected to corresponding electrode, therefore can ensure at a distance from the wire rod electrode different with current potential, so as to reduce Generate the risk of short circuit.As a result, being capable of providing the higher coil component of reliability.
