Description

Technical Field

[0001] The utility model relates to the technical field of surge protectors, in particular to a fireproof surge protector. Background Art

[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit.

[0003] When the surge protector is working, heat will be generated, especially when abnormal sharp pulses or surge currents appear in the circuit, the surge protector will activate the protection function. During this process, a certain amount of energy loss will be generated and converted into heat. If this abnormal situation occurs frequently or the overcurrent that the protector bears is too large, it will easily cause the internal temperature of the protector to rise. If the heat is not dissipated in time, the device may be burned out, and in serious cases, it may cause a fire.

[0004] Heat is more easily generated at the terminal of the surge protector because the terminal is the main channel for current to enter and leave the surge protector. The current flows here in a concentrated manner, which can easily cause local temperature rise. In addition, the quality and installation process of the terminal will also affect its heating. If the terminal has poor contact, is loose, or the wire specifications used are not appropriate, it may cause excessive resistance when the current passes through, thereby generating more heat, which will cause heat to accumulate at the terminal. Since the shell of the surge protector is usually irregular, it is difficult to directly make the air duct pass through the chamber where each terminal is located by using an exhaust fan for heat dissipation, and it is difficult to achieve the ideal heat dissipation effect. At the same time, the setting of the exhaust fan must necessarily preset an installation slot so that a larger area of ​​the terminal is directly connected to the outside, which can easily cause safety accidents. In addition, due to the limitation of the installation space of the surge protector, there is usually not enough installation space on the surge protector to install an exhaust fan, which brings great trouble to the heat dissipation and needs to be improved urgently.
