Abstract

PROBLEM TO BE SOLVED: To facilitate the measurement of a microelectic component by equipping a probe with a very small-sized television camera focused on the tip of the probe. SOLUTION: The probe tip 2 of a probe main body 1 is brought into contact with a measurement point, and a measurement signal of the measurement point is extracted. The probe is usually connected with a BNC connector or the like by using a coaxial cable. The signal is inputted in an oscilloscope or the like. A very small-sized television camera 3 is fixed to the probe main body 1 by using a metal fixture. A ground terminal clip 5 is connected with the ground level. The camera 3 is focused on the tip 2 of the probe 1. When a microelectric component or the like is measured, the tip 2 of the probe and a measurement point are magnified and displayed by displaying a picture signal of the camera 3 on a large monitor.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring probe used in an oscilloscope or the like.

[0002]

2. Description of the Related Art Conventionally, a measuring probe for inputting a measurement signal to a measuring instrument such as an oscilloscope has a conventional method of visually confirming a measuring point and supporting the probe with a hand by a measurer to bring the tip into contact with the measuring point. , The measurement signal is being extracted. However, in order to meet the recent demand for miniaturization of electric equipment, electric parts inside the equipment are becoming smaller and smaller, and as a result, the size of typical measurement points such as ic terminals tends to be extremely small. .

[0003]

The above-mentioned prior art includes the following:
In the measurement of the micro electric component as described above, it is difficult to visually contact the probe with the measurement point. An object of the present invention is to eliminate the above-mentioned drawbacks and provide a probe that can be used for measuring small parts.

[0004]

In order to achieve the above object, the present invention adds a microminiature television camera having a function of indirectly observing the tip of a probe and a point to be measured. As a result, when measuring ultra-small electrical parts, by displaying the video signal of the camera on a large monitor, etc., the tip of the probe that contacts can be enlarged and confirmed to easily measure the tip of the probe. The measurement signal can be extracted by touching a point.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG. Reference numeral 1 is a probe main body, and a measurement signal at the measurement point is extracted by bringing the probe tip into contact with the measurement point, and is usually connected to a BNC connector or the like by a coaxial cable to input the signal to an oscilloscope or the like.
Reference numeral 3 is an ultra-compact television camera, which is fixed to the probe main body 1 by means of the fixing brackets 4. Reference numeral 5 is a ground terminal clip, which is connected to the ground level. The camera is focused on the tip 2 of the probe 1. When measuring ultra-small parts, the tip of the probe and the measurement point can be enlarged and displayed by displaying the video signal of the camera 3 on a large monitor. The measurement can be performed by contacting the measurement point.

[0006]

According to the present invention, it becomes easy to measure ultra-small components and the like.
