Description

[Detailed Description of the Invention] This invention relates to a multi-terminal extraction device for testing, and more particularly to a multi-terminal extraction device suitable for conducting dielectric strength tests and sequence tests on a switchboard or the like having a large number of extraction terminals.

Conventionally, the method of conducting a dielectric strength test of a power distribution board, etc. is to loosen the terminal screws of the external connection terminal block installed on the power distribution board, wrap a binding wire, etc. around each screw, connect each terminal all at once, and apply the test voltage. was being applied.

Further, in order to conduct a sequence test, lead wires drawn out one by one from each terminal of the terminal block are connected to a test stand, and this test stand is operated.

However, in the former case, the terminal screw must be loosened for each wire.

Furthermore, the operator had to manually wrap the binding wire around the terminal screw and then remove the binding wire from the terminal screw after inspection, which was a tedious and time-consuming process.

In addition, since the conductive part is touched by hand at this time, there is a possibility that an unexpected electric shock may occur due to forgetting to turn off the main switch.

In the latter case, loosen the terminal screws one by one, connect the drawer lead wires, and tighten the terminal screws.After inspection, loosen the terminal screws again, pull out the wires, remove the lead wires, and tighten the terminal screws again. It was getting worse.

The present invention aims to eliminate the above-mentioned drawbacks and to provide a testing device that is simple in structure and easy to handle, allowing for easy testing.

In order to achieve this objective, the present invention includes a conductive coiled contact piece and a connector (female) electrically connected to the coiled contact piece.
and an insulating plate that integrates them is attached to the terminal block under test, the coiled contact piece is connected to each terminal of the terminal block under test, and the lead wire is connected to the connector (female). It is characterized in that each of the terminals can be drawn out by connecting via a male connector.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Fig. 1 shows the constituent members of the present invention, in which 1 is an insulating plate provided with a large number of through holes or eyelets 2 and 3, and printed wiring 4 is provided between these through holes or eyelets 2 and 3. .

A conductive coil-shaped contact piece 5 is fixed to each of the two groups of through holes or eyelets with solder 6.

A connector (female) 7 is attached to the insulating plate 1, and one end 9 of a contact 8 led out from the connector 7 is inserted into a through hole or three groups of eyelets and fixed with solder on the back side of the insulating plate 1. Ru.

Therefore, the insulating plate 1 and the connector 7 are integrated.

A connector (male) 11 having a contact 10 corresponding to the contact 8 is attached to the connector 7 .

A lead 12 is connected to each contact 10 of the connector 11, respectively.

FIG. 2 shows the state of use of the proposed device, where 13 is a terminal block to be tested, terminals 14 are provided in the length direction of the terminal block 13 (front and back direction in the paper), and terminal screws 15 are attached to each terminal 14. , 16 are screwed together.

An electric wire 17 is screwed onto one side of the terminal 14.
7 is connected to various devices in the switchboard.

The device of the present invention shown in FIG.
is formed, so the protruding side 18 is inserted into the hole 1 provided in the terminal block 13 by bending the insulating plate 1 to some extent.
Insert into 9.

The hole 19 is originally provided for fixing the cover of the terminal block 13, but since this hole 19 is utilized, no special mounting means is required.

Therefore, after installation, the coiled contact piece 5 deforms and maintains contact with each terminal screw 16, so wiring 17 - terminal 14 - terminal screw 16 - contact piece 5 - printed wiring 4 - contacts 8, 10 - lead wire 12 circuits and sequence tests can be performed.

On the other hand, each contact 10 of the connector 11 is electrically independent, but if it is replaced with a connector (male) 20 as shown in FIG. 3, a dielectric strength test can be performed.

In other words, in the connector 20 shown in FIG. 3, the contacts 10 are electrically connected to each other and led out to the screw 21 all at once, so it is only necessary to connect the lead wire 22 to the screw 21 and apply a predetermined voltage. .

As described above, according to the present invention, by preparing equipment that corresponds to the number of terminals on the terminal block, the lead wire connection work can be greatly reduced, and the handling operation is simple, making it possible to greatly improve sequence tests and dielectric strength tests. The effect can be easily implemented within a short period of time.

In the embodiment, printed wiring is used between the through holes or eyelets of the insulating plate, but lead wires may be connected instead of the printed wiring.
