Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device equipped with a transformer.

[0002]

2. Description of the Related Art A power supply device for supplying a stable voltage to robots and other electric products is often used not only in Japan but also in other countries. Therefore, the power supply voltage supplied to this power supply device may differ. For example, in the case of Japan, AC 100V is used, but in other countries, there are some countries that use a power supply voltage such as 110V or 120V.

However, when a plurality of power supply circuit boards corresponding to different power supply voltages are manufactured, the types of power supply circuit boards increase and management becomes complicated. Further, if the power supply device is manufactured after it has been decided in which region in Japan or other foreign countries to use, the time from order receipt to delivery will increase. Therefore, a transformer device, for example, a conversion connector and a transformer is used, and only by exchanging the conversion connector, different power supply voltages can be transformed into constant voltages and supplied to the power supply circuit board. That is, after the optional power supply device is completed and the area to be used is determined, the conversion connector may be replaced to complete the power supply device corresponding to the power supply voltage in the area.

A plurality of terminals 23b corresponding to respective power supply voltages such as 0V or 120V are provided.
Is connected to the electrode 22b of the fixed connector 22.
The conversion connector 9 is a connector for connecting the power supply voltage supplied from the outlet 20 and supplied to the electrode 22a through the connection line 21 to the electrode 22b corresponding to this power supply voltage.

Explaining an example of the replacement method when the power supply voltage is 100V, the conversion connector 9a corresponding to the power supply voltage 100V is used. First, a power supply voltage of 100 V is supplied to the outlet 20, and the electrode 22a is connected via the connection line 21.
The power source voltage of 100 V supplied to the conversion connector 9a connected to the fixed connector 22 and the fixed connector 2
The 100V terminal 23b of the transformer 23 is energized through the second 100V electrode 22b. And the power supply voltage 1
00V is transformed by the transformer 23 and supplied to the power supply circuit board from the secondary coil 23a. Therefore,
Even if different power supply voltages are supplied, the voltage output to the secondary coil 23a becomes constant by using the conversion connector 9 corresponding to each power supply voltage.

FIG. 7 is a perspective view showing a conventional conversion connector replacement method. The outer shell of the power supply device 30 is composed of a housing 32 and a cover 33. Power supply 3
In 0, one or a plurality of power supply circuit boards 31, a transformer 23, a fixed connector 22, a conversion connector 9a, etc. are housed.

Then, the replacement connector 9a is replaced as follows.

1. The screw 34 that fastens the cover 33 and the housing 32 is removed.

2. Remove the cover 33.

3. The conversion connector 9a installed on the fixed connector 22 and connected to the fixed connector 22 is removed.

4. The conversion connector 9c corresponding to an arbitrary power supply voltage is installed on the fixed connector 22 and connected.
