Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a packaging device for electrolytic capacitors used in general electronic equipment.

2. Description of the Related Art As a conventional packaging device for electrolytic capacitors of this type, a packaging device as shown in FIG. 3 has been used. In other words, Fig. 3 shows a state in which a plurality of electrolytic capacitors 2 are stored and packaged in a cardboard box 1 with one end open. A plurality of electrolytic capacitors 2 are housed in a compartment 4 divided by a member 3, and an opening at one end of the cardboard box 1 is closed with a flap 5.

Problems to be Solved by the Invention In general, electrolytic capacitors undergo aging by applying a voltage between the anode terminal and the cathode terminal of the electrolytic capacitor in order to stabilize their characteristics during the manufacturing process. The voltage stored in the electrolytic capacitor is discharged by shorting the anode and cathode terminals of the capacitor with a resistor, etc. The completed electrolytic capacitor is then packaged and shipped, but this electrolytic capacitor has the property of restoring voltage, and over time a voltage is generated between the anode and cathode terminals of the electrolytic capacitor. -The voltage that an electrolytic capacitor recovers from when fishing on a boat is high, and it is said that about 10% of the voltage applied during aging will recover. For example, if an electrolytic capacitor removed from a packaging device is attached to a set, the return voltage may destroy other parts, or if a person touches between the anode and cathode terminals of the electrolytic capacitor, they may receive an electric shock. This can cause problems such as The phenomenon of this voltage returning to 330V, D
When I investigated using a C260μF electrolytic capacitor, the fourth
The results are as shown in the figure, but as is clear from Figure 4, the voltage recovery phenomenon continues for a long time.
- No reliable measures can be taken against temporary discharges. In this case, it is economical and reliable to take measures using packaging equipment that stores electrolytic capacitors for a long period of time, but there is a problem in that conventional packaging equipment cannot be used as a countermeasure.

The present invention solves this problem by keeping the electrolytic capacitor in a discharged state even when the voltage returns, thereby constantly shorting the anode and cathode terminals of the electrolytic capacitor. An object of the present invention is to provide a packaging device for electrolytic capacitors that can be stored in a safe state.

Means for Solving the Problems In order to achieve the above objects, the present invention provides an electrolytic capacitor having an anode terminal and a cathode terminal on one end face, placed in a cardboard box with one end open, with the anode terminal and the cathode terminal facing upward. A sheet of conductive material is placed on the anode terminal and cathode terminal of these electrolytic capacitors, and an electrolytic capacitor having an anode terminal and a cathode terminal on one end surface is placed on top of the conductive material sheet. and the cathode terminals facing downward, and the conductive material sheets are sandwiched between the anode and cathode terminals of the lower electrolytic capacitor and the anode and cathode terminals of the upper electrolytic capacitor, and the cardboard is The opening at one end of the box is closed with a flap.

Conductive material sheets can be made of corrugated paper coated with conductive paint on both sides, conductive air caps in sheet form, or conductive metal foil or metal plates such as aluminum. This is what I did.

According to the present invention having the above-described structure, since the anode terminal and the cathode terminal of the electrolytic capacitor are always short-circuited by the conductive material sheet, the anode terminal and the cathode terminal are connected due to the phenomenon of voltage recovery of the electrolytic capacitor. This eliminates the problem of voltage being generated between the two. In addition, the conductive material sheet that short-circuits the anode and cathode terminals of an electrolytic capacitor is made of, for example, a sheet of corrugated paper coated with conductive paint on both sides, or a sheet of conductive air cap. , has a moderate elasticity, so it serves to protect the anode and cathode terminals, and the weight of the upper electrolytic capacitor slightly bites into the anode and cathode terminals of the electrolytic capacitor, so the gap between the anode and cathode terminals The short-circuiting of the two is also ensured.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, 11 is a cardboard box with one end open, and inside this cardboard box 11 there is an anode terminal on one end surface.
An electrolytic capacitor 13 having a cathode terminal 2a and a cathode terminal 12b,
The anode terminal 12a and the cathode terminal 12b are aligned upward.

A conductive material sheet 14 is placed on the anode terminal 12a and cathode terminal 12b of these electrolytic capacitors 13, and an anode terminal 15a and a cathode terminal 15b are further placed on one end surface of the conductive material sheet 14. The electrolytic capacitors 16 are aligned with the anode terminals 15a and cathode terminals 15b facing downward, and the anode terminals 12a and cathode terminals 12b of the lower electrolytic capacitor 13 are connected to the anode terminals 15a and cathode terminals 15b of the upper electrolytic capacitor 16. They are housed with the conductive material sheet 14 sandwiched between them. Further, one end opening of the cardboard box 11 is closed with a flap 17 after storing the lower electrolytic capacitor 13 and the upper electrolytic capacitor 16.

FIGS. 2(a), (b), and (e) show various types of conductive material sheets. The conductive material sheet 14 shown in FIG. 2(a) is coated with conductive paint on both sides of corrugated paper 18. 1
It is constructed by painting 8a. Further, the conductive material sheet 14 shown in FIG. 2(b) is a conductive air cap 19.
It is constructed in the form of a sheet. And again the second
The conductive material sheet 14 shown in Figure (e) is made of a conductive metal foil or metal plate 20 such as aluminum.

According to the configuration of the above embodiment, the lower electrolytic capacitor 1
3, and the anode terminal 15a and cathode terminal 15b of the upper electrolytic capacitor 16,
Since the lower electrolytic capacitor 13 and the upper electrolytic capacitor 16 are short-circuited by the conductive material sheet 14 and stored in the cardboard box 11, the lower electrolytic capacitor 13 and the upper electrolytic capacitor 16 Even if the voltage returns to , it will always be discharged, and as a result, the voltage will remain between the anode terminal 12a and the cathode terminal 12b of the lower electrolytic capacitor 13 and between the anode terminal 15a and the cathode terminal 15b of the upper electrolytic capacitor 16. These electrolytic capacitors 13.16 are not included in the set.
Even if you install it, it will not destroy other parts (
Furthermore, even if a person touches between the anode terminals 12a, 15a and the cathode terminals 12b, 15b of these electrolytic capacitors 13.16, there will be no electric shock, and thus a highly safe electrolytic capacitor can be provided. .

Effects of the Invention As is clear from the description of the embodiments above, the electrolytic capacitor packaging apparatus of the present invention stores an electrolytic capacitor having an anode terminal and a cathode terminal on one end surface in a cardboard box with one end open. and the cathode terminals facing upward, a conductive material sheet is placed on top of the anode terminal and cathode terminal of these electrolytic capacitors, and an anode terminal and a cathode terminal are further provided on one end surface on this conductive material sheet. Align the electrolytic capacitors with the anode and cathode terminals facing downward.
Since the conductive material sheet is sandwiched between the anode terminal and cathode terminal of the lower electrolytic capacitor and the anode terminal and cathode terminal of the upper electrolytic capacitor, the anode terminal of the upper and lower electrolytic capacitors This packaging device is included in the set because the terminals and cathode terminals are always short-circuited with the conductive material sheet, and as a result, voltage will not be generated between the anode terminal and the cathode terminal due to the phenomenon of voltage recovery of the electrolytic capacitor. Even if you install an electrolytic capacitor taken out from the factory, it will not destroy other parts, and even if a person touches between the anode and cathode terminals of the electrolytic capacitor, there will be no electric shock, making it a highly safe electrolytic capacitor. can be supplied.

In addition, the conductive material sheet that short-circuits the anode and cathode terminals of an electrolytic capacitor is made of, for example, a sheet of corrugated paper coated with conductive paint on both sides, or a sheet of conductive air cap. Due to its moderate elasticity, it serves to protect the anode and cathode terminals, and the weight of the upper electrolytic capacitor slightly bites into the anode and cathode terminals of the electrolytic capacitor, ensuring that there is no short circuit between the two terminals. This is something that can be done by
