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 acing is recovered. 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. It causes problems such as receiving or receiving. When we investigated this voltage recovery phenomenon using a 330V, DC 260μF electrolytic -1 capacitor, we found the results shown in Figure 4.As is clear from Figure 4, the voltage recovery phenomenon lasts for a long time. Since the discharge continues for a long period of time, no reliable measures can be taken against temporary discharge. 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 state in which the electrolytic capacitors are stored in an exposed state.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a method in which a sheet of conductive material is laid in a cardboard box with one end open, and an anode terminal is placed on one end of the sheet of conductive material. An electrolytic capacitor having a cathode terminal is housed in alignment so that the anode terminal and cathode terminal are in contact with a conductive material sheet, and one end opening of the cardboard box is closed with a flap.

In addition, the conductive material sheet is made of corrugated paper coated with conductive paint on one side, a sheet of conductive air cap, or a conductive metal foil or metal plate 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. It also constitutes a conductive material sheet that short-circuits the anode terminal and cathode terminal of the electrolytic capacitor. For example, corrugated cardboard coated with conductive paint on one side, or conductive air caps in sheet form, have a moderate amount of elasticity, so they act as protectors for the anode and cathode terminals, as well as for electrolytic capacitors. Because the weight of the electrolytic capacitor slightly bites into the anode and cathode terminals of the electrolytic capacitor, short-circuiting between the anode and cathode terminals is ensured.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, reference numeral 11 is a cardboard box with one end open, and inside this cardboard box 11 is a conductive material sheet 12.
is laid down. An electrolytic capacitor 14 having an anode terminal 13a and a cathode terminal 13b on one end surface is housed on the conductive material sheet 12 such that the anode terminal 13a and the cathode terminal 13b are in contact with the conductive material sheet 12. . Further, one end opening of the cardboard box 11 is closed with a flap 15 after storing the electrolytic capacitor 14 therein.

FIGS. 2(a), (b), and (c) show various types of conductive material sheets. The conductive material sheet 12 shown in FIG. 1
It is constructed by painting 6a. Further, the conductive material sheet 12 shown in FIG. 2(b) is a conductive air cap 17.
It is constructed in the form of a sheet. And again the second
The conductive material sheet 12 shown in Figure (C) is constructed from a conductive metal foil or metal plate 18 such as aluminum.

According to the configuration of the above embodiment, the anode terminal 13a and the cathode terminal 13b of the electrolytic capacitor 14 are connected to the conductive material sheet 1.
Since the electrolytic capacitor 14 is stored in the cardboard box 11 with the electrolytic capacitor 14 short-circuited, even if the voltage is restored to the electrolytic capacitor 14, it is always discharged, and as a result, the electrolytic Anode terminal 1 of capacitor 14
Since no voltage is generated between 3a and cathode terminal 13b, even if this electrolytic capacitor 14 is installed in the set,
Other parts will not be destroyed (and even if a person touches between the anode terminal 13a and the cathode terminal 13b of the electrolytic capacitor 14, there will be no electric shock, thereby providing a highly safe electrolytic capacitor. be able to.

Effects of the Invention As is clear from the description of the above embodiments, the electrolytic capacitor packaging apparatus of the present invention is such that a sheet of conductive material is laid in a cardboard box with one end open, and a sheet of conductive material is placed on top of the sheet of conductive material. An electrolytic capacitor having an anode terminal and a cathode terminal on one end surface is arranged and housed so that the anode terminal and cathode terminal are in contact with a conductive material sheet, so that the distance between the anode terminal and the cathode terminal of the electrolytic capacitor is The electrolytic capacitor taken out from this packaging device as a set is always short-circuited by the conductive material sheet, and as a result, no voltage is generated between the anode terminal and the cathode terminal due to the phenomenon of voltage recovery of the electrolytic capacitor. Even if the electrolytic capacitor is installed, other parts will not be destroyed (and even if a person touches between the anode terminal and the cathode terminal of the electrolytic capacitor, there will be no electric shock, so we supply highly safe electrolytic capacitors. I can do it.

In addition, the conductive material sheet that short-circuits the anode and cathode terminals of an electrolytic capacitor is made of a sheet of conductive material, such as a sheet of corrugated paper coated with conductive paint on one side, or a sheet of conductive air cap. Because of its moderate elasticity, it serves to protect the anode and cathode terminals, and the weight of the 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. It is something that can be done.
