Description

Technical Field

[0001] The present invention relates to the technical field of lightning arresters for communication power supplies, in particular to a pluggable lightning arrester. Background Art

[0002] Power supply lightning arresters (SPDs) are also known as lightning arresters, surge protectors, and surge protectors. In the information age, computer networks and communication equipment are becoming more and more sophisticated, and the requirements for their working environment are also getting higher and higher. Lightning and instantaneous overvoltages of large electrical equipment will more and more frequently invade indoor electrical equipment and network equipment through power supplies, antennas, radio signal transceivers and other lines, causing damage to equipment or components, casualties, interference or loss of transmitted or stored data, and even causing electronic equipment to malfunction or temporarily paralyze, system pauses, data transmission interruptions, and local area networks and even wide area networks to be damaged. The hazards are shocking, and indirect losses are generally far greater than direct economic losses. Power supply lightning arresters are equipment that uses modern electrical and other technologies to prevent lightning strikes. The new generation of communication power supplies (5G power supplies) require small size and high energy density, so key devices also need to be miniaturized and lightweight; lightning arresters are the main components of communication power supplies. Current communication power supply lightning arresters have the following defects:

[0003] Traditional lightning arresters have a loose structure and large size, making them difficult to adapt to the iterative requirements of communication power supplies. In addition, traditional lightning arresters use traditional socket connection methods, and customers need to make adapter cables for connection, which is not convenient. Traditional lightning arresters use micro switches to realize remote signal collection, which is costly and large in size, and requires too many solder joints. The more solder joints, the worse the stability. Moreover, lightning arresters often require multiple interconnections depending on the application scenario.
