Description

TECHNICAL FIELD The present invention relates to a tool for electrically connecting a device under test and a measuring device in order to verify (hereinafter referred to as a test) the electrical performance of an electrical product. .

[Conventional technology]

FIG. 5 is an explanatory diagram showing an example of a conventional connection method. In the conventional test method, in order to test the device under test 21, for example, when a plurality of measuring devices 24 are required, a measuring circuit suitable for the test purpose is configured between the plurality of measuring devices,
A relay terminal 23 is separately provided for connection with the DUT 21,
The terminal 25 at the tip of the electric wire 22 of the DUT 21 was connected to the relay terminal 23.

[Problems to be Solved by the Invention]

In the conventional method, it is necessary to connect the terminals 25 attached to the electric wires 22 of the DUT 21 to the relay terminals 23 one by one, and to remove these terminals again one by one when the test is completed. Therefore, when the number of electric wires of the DUT 21 is large, a large number of man-hours are required to attach and detach these terminals 25.

Therefore, an object of the present invention is to reduce the number of man-hours for attaching / detaching a terminal at the time of test by connecting and disconnecting the terminal on the DUT side and the relay terminal with one touch.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention has a pedestal for inserting and holding terminals of a plurality of electric wires on the side of a DUT, and an electric terminal for each electric wire inserted into the pedestal to be electrically contacted individually. A test wiring terminal connecting tool including a connecting pin, a pin receiver for collectively attaching the connecting pins, and a link mechanism for moving the pin receiver in a direction of contacting and releasing the terminal of the electric wire and the connecting pin is used. As a result, the number of man-hours for attaching and detaching the terminal is reduced.

[Action]

When the test wiring terminal connecting tool (hereinafter referred to as the connecting tool) according to the present invention is used, the connecting pins corresponding to each of the plurality of terminals on the side of the DUT inserted and held in the cradle are simultaneously connected by the link mechanism. Since it is possible to move to and connect and disconnect with one touch, the number of man-hours for attaching and detaching terminals at the time of testing can be reduced.

〔Example〕

1 and 2 are a front view and a plan view showing a structure of an embodiment of a connecting tool of the present invention, and FIG. 3 is a sectional view taken along line III-III in FIG.

The structure of this connecting tool will be described mainly with reference to FIG.

The rail 2, the guide 3, and the pedestal 4 are fixed to the base plate 1. Insert the guide shafts 5, 5A into the guide 3 slidably,
A pin receiver 6 is fixed to one end of 5A, and a slider 7 is fixed to the opposite end. The slider 7 is slidably fitted in the rail 2 in a groove 8 of the slider 7 so that the slider 7 can slide in the longitudinal direction of the rail 2.

A fixed shaft 9 is provided on the rail 2 at the opposite end of the guide 3, and a handle 10 is rotatably attached to the fixed shaft 9. The handle 10 and the slider 7 are connected by a lever 11, and the connecting portion is rotatable by pins 12 and 13.

A plurality of connecting pins 14 are slidably fitted in the pin receiver 6, an electric contact 15 is provided at one end of the connecting pin 14, and the electric contact 15 is biased by a spring 16 in a direction away from the pin receiver 6. There is. The pin receiver 6 is made of an insulating material in order to electrically insulate the connection pins 14 from each other. A terminal 17 provided on the opposite end of the electrical contact 15 of the connecting pin 14 is connected to the measuring circuit for testing.

The slider 7 is biased by a spring 18 in a direction away from the guide 3 and is pressed against the handle 10 to stand still.

With the connecting tool configured as described above, insert the terminal 25 of the electric wire 22 of the DUT 21 into the pedestal 4 and attach the handle 10 to the fixed shaft 9
When it is rotated counterclockwise about, the force moves the slider 7 along the rail 2 toward the guide 3 via the lever 11, and the movement is performed via the guide shafts 5 and 5A and the pin receiver 6. The electrical contact 15 of the connection pin 14 is pressed against the terminal 25 by the force of the spring 16 to electrically connect the DUT 21 and the measurement circuit.

FIG. 4 shows that the handle 10 is rotated counterclockwise so that the terminal 25 on the DUT 21 side and the electrical contact 15 provided on the connection pin 14 are provided.
It is an operation explanatory view showing a state where and are pressed against each other. In this state, the center of the pin 12 of the lever 11 is located beyond the straight line 20 connecting the center of the fixed shaft 9 and the center of the pin 13 of the lever 11, so that the handle 10 maintains that state. Further, a stopper 19 is provided on the rail 2 to stop the handle 10 so that the handle 10 does not rotate too much in this state.

When the handle 10 is returned to the original position from the state shown in FIG. 4, the state shown in FIG. 1 is restored, and the electrical connection between the DUT 21 and the measuring circuit is released.

〔The invention's effect〕

By using the connection tool of the present invention, it is possible to connect and disconnect the terminals of a plurality of electric wires on the DUT side and the relay terminals of the measurement circuit with a single touch by operating the handle, so the number of man-hours for attaching and detaching the terminals during the test can be reduced. It can be reduced to about 1/5 compared to the conventional one.
