JPS5914774Y2 - Terminal clip for measuring electrical signals - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel structure of a tube used in measuring electrical signals.

Traditionally, clips for measuring electrical signals have a crocodile shape.
It only has a clipping function, which poses a problem especially when used in small areas with intricate wiring, and therefore a separate measurement terminal member had to be used.

The present invention was developed in view of the above-mentioned drawbacks of the conventional clips, and can be used as a regular clip, and by changing the shape, it is convenient as it allows for easy extraction of electrical signals even in areas with crowded wiring. The purpose of this invention is to provide a terminal clip for measurement.

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 1 shows a side view of an embodiment of the electrical signal measuring terminal clip according to the present invention, and FIGS. 2 to 4 show partial side views of the same clip.

As shown in FIG. 1, numeral 1 is a clip main body, and its structure is divided into two parts.

A needle-like projection 2 is rotatably provided at the tip of the clip body 1, and the needle-like projection 2 is engaged in a fixing hole 3.

Further, the clip body 1 is provided with a spring member 4, which provides elastic force for clipping.

Reference numeral 5 denotes a lead wire fixing protrusion, through which the lead wire is connected.

In the figure, the needle-like protrusion 2 has an elongated shape and can be brought into contact with the measurement point accurately even in a place where circuit wiring is crowded.

FIG. 2 shows a setting state in which the needle-like protrusion 2 is fixed at an angle of 90 degrees from the clip main body 1 through the fixing hole 3.

In this state, the portion of the needle-like protrusion 2 that protrudes from the main body becomes shorter, and has the same effect as if the protrusion 2 had a different length from that shown in FIG. 1.

FIG. 3 shows a state in which the needle-like protrusion 2 is housed in the clip body 1, and when the needle-like protrusion 2 is not needed, the protrusion 2 does not get in the way.

FIG. 4 shows another state of use of the needle-like protrusion 2 described above.

That is, the electrical signal can be measured even from outside the insulation coating of the lead wire 6 by piercing the insulation coating with the needle-shaped protrusion 2.

At this time, the material, length, etc. of the needle-like protrusion 2 are appropriately selected.

As explained above, according to the present invention, since the clip body is equipped with a rotatable needle-like protrusion, the needle-like protrusion allows immediate measurement even in areas where wiring is crowded, making it very convenient. be.

[Brief explanation of the drawing]

FIG. 1 is a side view of a terminal clip for measuring electrical signals according to the present invention, and FIGS. 2 to 4 are partial side views of the clip. In the figure, 1: clip body, 2: needle-like projection, 3: fixing hole,
4: Spring material, 5: Lead wire fixing protrusion, 6: Lead wire.
