Abstract

PURPOSE:To prevent destruction and damage of electric and electronic apparatuses by selecting one of plural voltage terminals of a transformer by means of a jumper line block and connecting the selected voltage terminal with a single power supply terminal. CONSTITUTION:The terminal of each voltage E1-E4 transformed by a transformer 2 connected with a power source 1 is selected by means of a jumper line 8 and led to a single power supply terminal 7 from which power is supplied to electric and electronic apparatuses. When such constitution is used, the voltage of the power source 1 is transformed by the transformer 2 and the voltages E required by the electric and electronic apparatuses can be supplied through the jumper line 8 and terminal 7. The jumper line 8 is set by means of a jumper block 9, but the jumper block 9 is selected by means of power supply specifications of the electric and electronic apparatuses. Moreover, when once terminal setting is preformed, the selecting operation is not required for testing the same apparatus.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an 11 source supply device 1, inter alia.

This article relates to a W source supply system used in all IK electrical and electronic equipment.

[Prior Art] Figure 2 shows a power supply device conventionally used for testing general KII electrical and electronic equipment. In Figure 1, electricity is taken out from terminals (outlets) (3) to (6). ing.

With the above configuration, the voltage of the 1M source (1) is transferred to the transformer (2).
Denki II! The ILF source voltage required for testing slave devices is converted. General K, what is the power supply voltage for electrical and electronic equipment?

In the identified device a, terminal (3) K hail (El)
voltage at terminals (4) on other identified equipment.
) is normally determined to use the voltage (E2) that is not available in the building, that is, it is compatible with the power supply voltage of each building.

[Problem to be solved by the invention]

Since the conventional power supply device is configured as described above, the terminal that meets the power supply voltage of the specified electronic device (E+
) to (E4) must be selected, and if the selection is incorrect, the electronic equipment may be destroyed or damaged, so sufficient measures and precautions must be taken each time the test is repeated.

This invention was made to solve the above problems, and eliminates the need to select terminals (E+) to (E4).
It is an object of the present invention to obtain a power supply device that does not require special weight even when repeated tests are performed after voltage selection is performed only once.

[Means for solving confusing problems]

The power supply device according to the present invention is configured to select a plurality of voltage terminals of a transformer using a jumper wire block and connect them to a single power supply terminal.

[For production]

In this invention, a block of jumper wires is selected according to the source specifications of the electrical/electronic equipment to be tested, and the necessary voltage is supplied to the electrical/electronic equipment, and after terminal settings are completed, when testing the same equipment, does not require terminal selection.

〔Example〕

FIG. 1 shows an embodiment of the present invention, in which each voltage (El) to
(E4) end cannot be led to a single 11I' source supply terminal (7) selected from jumper & (81K to supply the electrical/heavy equipment KII source.
) is a jumper wire block containing.

With the above configuration, the voltage of the electric current I%I (1) is changed to the voltage of the transformer (2
), and the voltage (El) required by the electronic equipment can be supplied via the jumper wire (8) and the power supply terminal (7).This jumper wire ( 8) is set by a jumper wire block (9), and this jumper wire block (9) is selected depending on the power supply specifications of the electric/electronic equipment.

Furthermore, once the terminal settings are completed, no selection operation is required when testing the same device.

〔Effect of the invention〕

As described above, according to the present invention, the power supply terminal is
This prevents mistakes in terminal selection, and since the jumper wire block is selected after checking the specifications of the electrical/electronic equipment, destruction and damage to the electrical/electronic equipment can be prevented.
