Description

Technical Field

[0001] The utility model relates to the field of installation of surge protectors, in particular to a surge protector anti-wrong-insertion device. Background Art

[0002] Lightning is one of the main reasons for damage to electronic equipment. It threatens the safe and stable operation of electronic information systems in various industries such as railways, civil aviation, communications, industrial control, and military. Installing surge protectors on metal lines such as power lines, signal lines, and control lines connected to electronic equipment is one of the important measures for lightning protection. At present, lightning protection in many special fields requires the use of surge protectors installed by plug-in methods. Surge protectors can be installed by connecting to wiring terminals through plug-in devices.

[0003] However, in practical applications, various electronic equipment circuits usually have different technical parameter requirements (such as operating voltage, current, insertion loss, matching impedance, etc.), so a matching surge protector should be selected. Surge protectors with different technical parameters are likely to use the same wiring terminals, or have the same or similar appearance. If there is a slight negligence, installation errors may occur, causing the surge protector to burn out or even explode, threatening the personal safety of the installer; or failing to provide lightning protection; it may also cause the protected equipment to work abnormally.

[0004] There are two existing solutions. One is to use text labels to indicate the main technical parameters of the surge protector in a conspicuous position to remind the installer to install it on the matching wiring terminal. The other method is color identification. Surge protectors of different models and parameters are selected in different colors to distinguish surge protectors of different models and parameters. However, neither of these two methods can completely avoid incorrect installation. Utility Model Content

[0021] In this embodiment: after the surge protector 2 is damaged, the shielding component is pulled down to rotate the rotating plate 5 of the shielding component downward. When the rotating rotating plate 5 rotates downward, it drives the reset component to deform, and then the damaged surge protector 2 is removed. At this time, the force applied to the rotating plate 5 is removed. At this time, the reset component drives the rotating plate 5 to reset to the initial position, and then a new surge protector 2 is taken out. Before installation, the parameters engraved on the new surge protector 2 are compared with the parameters on the rotating plate 5.
