Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a series of taped electronic components.

As shown in FIG. 1, a conventional electronic component chain has been used in which lead wires 2 and 3 led out from a plurality of electronic components 1 are sandwiched between a taping material 6 consisting of a continuous mount 4 and adhesive tape 5. . However, when the electronic component is an electrolytic capacitor, if the lead wires 2 and 3 are formed near the base of the sealing part and attached to the taping material 6 as shown in Figure 1, the capacitor's sealing part will be closed using an elastic sealant or the like. Since the electrode foil is sealed, mechanical stress during molding is transmitted to the electrode foil through the lead wires 2 and 3, damaging the oxide film and increasing leakage current.

In general, if electrolytic capacitors are stored for a long time, leakage current tends to increase, and they may be aged by applying voltage again, but capacitors that are taped as mentioned above have the disadvantage that they cannot be easily energized. It was hot.

The present invention eliminates the above-mentioned drawbacks and provides an electronic component chain that allows easy energization of taped electronic components.

The present invention will be explained below with reference to embodiments shown in FIGS. 2 to 5.

FIG. 2 is an exploded front view of the main part of the taped electronic component. Two conductive tapes 7a and 7b made of aluminum or the like are provided on the mount 4, and the lead wire 2 of one of the conductive tapes 7a intersects with the lead wire 2. The parts that are connected to each other are insulated by an insulating material 8. 9 is a feed hole, 10 is an adhesive tape, one lead wire 2 of the electronic component 1 contacts the conductive tape 7a, and the other lead wire 3 contacts the conductive tape 7b, so the electronic component 1 is not taped. In this state, all the units will be connected in parallel.

Therefore, since the electronic component 1 is taped and the electronic component series packed by a method such as reel winding or zigzag folding, electricity can be applied to the electronic component 1 from the end of the taping mount 4 through the conductive tapes 7a and 7b. If aging is required, such as with an electrolytic capacitor, a voltage can be easily applied from one end of the taping mount 4.

3 and 4 show other embodiments. In FIG. 3, the mount 4 is provided with a slit 11, the lead wire 2 is inserted from the back side of the mount, and the adhesive tape 10 is pasted. , conductive tape 7a
At the same time, the lead wire 3 also contacts the conductive tape 7b.
This has the same effect as described above.

In FIG. 4, one lead wire 2 of the electronic component 1 is placed on one side of the mount 4, and the other lead wire 3 of the electronic component 1 is placed on the other side of the mount 4, and conductive adhesive tapes 12 and 13 are placed on the mount 4. The lead wires 2 and 3 are brought into contact with each other and fixed to the mount 4, and the same effect can be obtained.

In addition, instead of the conductive material for conducting electricity on the continuous conductive tapes 7a and 7b described above, a conducting path may be provided by metal vapor deposition on the continuous mount 4, or a thin flexible conducting wire may be arranged. . Further, the conductive material for current supply may be provided on the adhesive tape 10 side, and in either case, at least a portion of the taping material is made of a continuous conductive material for current flow, and the lead wires 2 and 3 of the electronic component 1 are contacted to the conductive material. What is being held is
Various combinations are possible.

Further, by coloring one pole side of the above-mentioned conductive material for energization, the polarity classification when energizing can be made clearer and safety can be improved.

Figure 5 compares the leakage current characteristics of an electrolytic capacitor with a rating of 50 WV 1 μF, which is obtained by aging a sample taped according to the present invention and by a conventional product which is taped after aging. It was confirmed that the device of the present invention has significantly reduced leakage current and is stable. Furthermore, the variation in leakage current was small, and it was proven to be effective.

As mentioned above, the electronic component series of the present invention is extremely advantageous in terms of quality and energization processing, and is of great industrial and practical value.
