Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an aging device for non-polar electrolytic capacitors that simultaneously applies a DC voltage to a plurality of non-polar electrolytic capacitors.

Prior Art Conventionally, when performing aging treatment on non-polar aluminum electrolytic capacitors, an aging device for polar aluminum electrolytic capacitors has been used. That is, terminals 2a, 2b of a plurality of capacitors 1 are connected to an aging device 11 as shown in FIGS. 3 and 4.
was inserted, and the aging process was performed by applying electricity from the DC power supply 14. 12 is a diode.

However, when using this device, voltage can only be applied in one direction, so in order to age a non-polar electrolytic capacitor, it is necessary to insert the capacitor into the aging device twice.

Problems that the invention aims to solve: When aging non-polar aluminum electrolytic capacitors in the aging equipment for polar aluminum electrolytic capacitors, it takes twice as long to age them as compared to polar products. If you age only the polarity once and then reverse the polarity of the capacitor and insert it into the jig, some capacitors may be energized without being reversed by mistake, resulting in unaged products. In addition, when the capacitor body is reversed and inserted into the jig, mechanical stress is applied, causing problems such as leakage current failure.

Means for Solving the Problems The present invention solves the above-mentioned problems.In an aging device for electrolytic capacitors in which a plurality of capacitors are arranged in a jig and current is applied to the terminals of the capacitors, each capacitor is A diode in the forward direction and a diode in the reverse direction are connected to the same terminal of the device, and a first electrode that can conduct current to the diode in the forward direction and a second electrode that can conduct current to the diode in the reverse direction are provided. This is an aging device for non-polar electrolytic capacitors.

Function The aging device that holds the electrolytic capacitor is equipped with a diode in the forward direction and a diode in the reverse direction, so that current can be passed from both directions without reversing the body of the non-polar aluminum capacitor.This eliminates stress on the capacitor and shortens the aging time. can be shortened. At the same time, it also has the effect of preventing the generation of unaged products.

Embodiment The present invention will be explained below based on the embodiment shown in FIGS. 1 and 2.

FIG. 1 is a perspective view of the main part of the aging device, and FIG. 2 is an explanatory diagram of its electric circuit. When a capacitor 1 is inserted into the aging device 3, it is electrically connected to the same terminal 2a or 2b of the capacitor. Forward direction diodes 4a, 4b and reverse direction diodes 5a, 5b are provided. The diodes 4a, 4b in the forward direction are connected to a pair of first electrodes 6a, 6b that can be energized from the outside, and the diodes 5a, 5b in the reverse direction are connected to a pair of second electrodes 7a, 7b.

Next, a usage example of the above-mentioned aging device will be explained.

The aging device 3 includes a pair of first electrodes 6a,
6b and second electrodes 7a and 7b on the left and right, the capacitor 1 is continuously transferred in parallel into a high temperature furnace and exposed to high temperature. At first, the power supply bar in the furnace comes into continuous contact with the pair of first electrodes 6a, 6b,
Current is continuously applied to the capacitor 1 in the positive direction from the DC power supply 9 through the diodes 4a and 4b. After being transported a predetermined distance in the furnace and energized for a certain period of time, the first electrodes 6a and 6b are disconnected from the power supply bar and connected to a discharge circuit so that the charges stored in the plurality of capacitors 1 are simultaneously discharged. be done. Next, the power supply bar continuously contacts the pair of second electrodes 7a, 7b, and current is continuously applied to the capacitor 1 from the DC power source 10 in the opposite direction through the diodes 5a, 5b. Then, in the same manner as described above, after being transported a predetermined distance in the furnace and energized for a certain period of time, the second electrode 7
a and 7b are disconnected from the power supply bar and connected to a discharge circuit so that the charges stored in the plurality of capacitors 1 are simultaneously discharged.

As described above, the capacitor 1 is alternately energized in the forward and reverse directions to the pair of independent first and second electrodes.

In the above embodiment, the protrusion lengths of the first electrode and the second electrode are different as shown in FIG. 1, but either one of them may be energized first, or It goes without saying that the protrusion lengths may be the same by arranging them above and below with respect to the direction in which the protrusions are made.

It is also possible to omit one of the diodes 4a, 4b or 5a, 5b and connect the capacitor directly to the electrode, or omit the diodes 4b, 5b and connect the electrode 6b.
and 7b may be connected directly from the capacitor to an integrated electrode.

Effects of the invention Since the aging device for non-polar electrolytic capacitors of the present invention is configured as described above, the product is not removed from the aging device, reversed and reinserted into the same device during the process of switching the polarity direction of energization. Therefore, the number of man-hours is greatly reduced, and problems such as incorrect insertion of the product or mechanical stress applied to the capacitor terminals resulting in leakage current defects do not occur, making it suitable for industrial and practical applications. It is of great value.
