Description

Technical Field

[0002] A relay is an electrical control device that is widely used in various electrical equipment and systems. It opens and closes the circuit through electromagnetic attraction and release, and plays the role of amplifying, isolating, protecting and controlling electrical signals. However, due to the wide variety of relays and different specifications, it is particularly important to correctly identify the type and parameters of the relay when using it, especially when testing the relay. Each relay has its specific specifications, including current, voltage, power, insulation resistance, contact resistance, action time, etc. When purchasing a relay, it is necessary to select appropriate specifications according to actual needs to ensure that the relay can work normally and meet system requirements. However, even relays of the same brand have many different models. The appearance characteristics of the relay are one of the most intuitive and simplest identification methods. The relay is usually composed of a shell, contacts, coils, and terminals. By observing the shape, color, and logo of the shell, the type and purpose of the relay can be preliminarily judged. However, some similar-looking models cannot be judged by appearance recognition. Therefore, a relay identification tool is proposed. Utility Model Content
