Description
Technical field
The present invention relates to electronic unit and its production method; and more particularly; relate to a kind of electrolytic capacitor and its production method; this electrolytic capacitor is an example of electronic unit; this electrolytic capacitor has the type that comprises a plurality of electrode foils; these electrode foils twist in a plurality of insulating papers that are inserted between the electrode foil; electrode foil has the straight portion of attached lead thereon respectively; wherein protection sheet is bonded on the insulating paper respectively; thereby the electrical insulation characteristics between the raising electrode foil; insulating paper contacts with two sides of the straight portion of lead; and wherein protection sheet is bonding in such a manner; this mode makes protection sheet can not increase the thickness (diameter) of Mansbridge capacitor significantly; and can not increase the equivalent series resistance (ESR) of Mansbridge capacitor; perpendicular to carrying the insulating paper that to roll and the direction of electrode foil, just in time before the insulating paper zone of bonding protection sheet is rolled, protection sheet is supplied to insulating paper along substantially.Thereby the protection sheet with preset width (length on the roll up direction) is bonded on the insulating paper respectively, thus two sides of the straight portion of guardwire, and described preset width is wider than the width of the straight portion of lead slightly.
Background technology
Electrolytic capacitor as an example of electronic unit is formed with the element that comprises a plurality of electrode foils usually, and promptly for example two plate electrode paper tinsels twist in two insulating papers that are inserted between the electrode foil.This element also comprises protection sheet, and protection sheet is bonded in respectively on the insulating paper, and insulating paper contacts with at least one side of the straight portion of positive negative conductor, thereby has improved the electrical insulation characteristics between the electrode foil.
Electrolytic capacitor need have less equivalent series resistance (ESR) electrical characteristic usually, and ESR causes owing to driving electrolytic solution (driving electrolytic solution).In order to reduce resistance, need insulating paper to be suitable for keeping the driving electrolytic solution of capacity, and these paper are the thinnest as far as possible, and have the thinnest as far as possible density, as long as these paper can not produce short circuit.In this respect, on market, can obtain the quite thin insulating paper that possesses good characteristic in fact in recent years.
Must be noted that also the shape that forms the fiber of insulating paper will influence the series resistance relevant with transfer rate with the transmission distance of electrolytic solution with distributing.
Also must be noted that; for the electric insulation between the straight portion that improves positive negative conductor; the paper that needs protection has optional thickness and length on roll up direction (width of protection sheet); positive negative conductor is attached on the electrode foil that insulating paper twists in; protection sheet is bonded on the insulating paper respectively; insulating paper contacts with a side of the straight portion of lead, thus guardwire fully, and reduce the ESR of capacitor.
Yet the protection sheet that is bonded in the routine on the insulating paper is quite long on roll up direction (being the width of protection sheet), and with respect to the conveying of rolling of insulating paper and electrode foil, with suitable morning ground regularly supply with insulating paper.
For example, Figure 27 has shown the electrolytic capacitor element of rolling 2 as an example of electronic unit.In this example, positive and negative electrode paper tinsel 4 (cathode foil 4P, anode foil 4M) has by piercing device etc. and positive negative conductor 3 (positive wire 3P fixed thereon, cathode conductor 3M) the straight portion 3b of joint 3a, positive and negative electrode paper tinsel 4 by the roll-up device (not shown) by counterclockwise and be inserted in insulating paper 5 between the electrode foil (5A 5B) twists in together.And be approximately the protection sheet 6 of 10～11 double-lengths of width (being the length of straight portion 3b on roll up direction) of straight portion 3b of the joint 3a of lead 3; its time of delivery of rolling with respect to insulating paper is supplied with timing early; thereby be bonded on the zone of insulating paper 5A; the side of insulating paper 5A and lead 3P and the side of lead 3M contact, and extend between it.
Yet the protection sheet 6 of this length is used for only protecting the side of the straight portion 3b of these two leads 3.In addition, its shortcoming is that long protection sheet 6 will increase the thickness (diameter) of electrolytic capacitor element 2, and will strengthen the electrical characteristic of electrolytic capacitor 1, especially ESR simultaneously.
In addition; two sides for the straight portion of protecting these two leads; need to prepare protection sheet 6A and another protection sheet 6B, protection sheet 6A is approximately 26 double-lengths of the width of straight portion 3b on throughput direction, and protection sheet 6B is approximately 10 double-lengths of the width of straight portion 3b on throughput direction.That is, the total length of protection sheet 6 to be rolled is approximately 36 double-lengths of the width of straight portion 3.Therefore will increase the thickness (diameter) of electrolytic capacitor element 2 like this.The result; shortcoming is that electrolytic capacitor 1 will become too greatly and too heavy; and electrical characteristic; especially ESR; to increase to about 3.6 times such big of as shown in Figure 27 conventional electrolysis capacitor with simple calculating; in the electrolytic capacitor of routine, each straight portion 3b of each lead 3 has only a side to be protected.
According to prior art, protection sheet is long inevitably on roll up direction because the insulating paper part of rolling bonding protection sheet thereon very early before, protection sheet is just supplied with insulating paper with timing early.
This paper does not show and relates to document of the present invention, because inventor and/or applicant fail to find this document.
