AI Technical Summary
Existing portable testers are not sufficiently portable and efficient, particularly when using LEDs with varying voltages and polarities, which can lead to weakened light emission and difficulty in polarity identification.
A highly portable tester design utilizing safety pins as probes, where two LEDs are connected in series to eliminate polarity issues and increase the strength of the LED feet, allowing for safe and efficient use as a power checker.
The solution enables the creation of a highly portable and practical power checker that is safe to use and aesthetically appealing, with the option to use 7-colored LEDs for enhanced visual appeal.

Abstract
Description
[Technical field]
[0001] The present invention relates to a tester. [Background technology]
[0002] There are testers that use lights to indicate the status. For increased portability, you can attach it to your clothing using a safety pin or keychain. If you apply 3V to a 5V LED, the light will be weaker but it will still glow. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] none Summary of the Invention [Problem to be solved by the invention]
[0005] To realize a highly portable tester. [Brief description of the drawings]
[0006] [Figure 1] FIG. 1 is a diagram illustrating an example of a configuration of a tester according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007] In the tester of the present invention, one or both of the probes are safety pins.
[0008] According to the present invention, a highly portable tester can be manufactured. EXAMPLES
[0009] Attach an LED to the non-needle side of the safety pin (between the spring part and the metal part) to use as a tester. The minimum configuration consists of one safety pin and one light-emitting diode, but if the pins of the light-emitting diode are exposed, there is a risk of them being bent or punctured. In addition, most LEDs have polarity, and polarized types are cheaper. If there is only one LED, it is difficult to use it as a current checker because of the polarity. So, connect the positive and negative terminals of two LEDs together, and connect one end to a safety pin. The connection can be done with tape, glue, or soldering. By connecting two LEDs together, the strength of the LED legs is increased, there is no part that can be pierced, polarity is eliminated, and one end can be connected to wiring, etc. By attaching safety pins to both legs of the LED, it becomes a practical power checker that looks cool. Since this is the era of gaming accessories, it would look cooler if it used an LED that lights up in seven colors. The safety pin must be made of a material that conducts electricity. A clear example is shown in FIG. Although a key chain ring can be used as a tester instead of a safety pin, there are problems such as not being able to insert it into narrow spaces. A keychain is good for measuring 100V or so, but at that size, it is sufficient to attach a keychain ring to an ordinary small tester. [Explanation of symbols]
