Abstract
Description
Technical Field
[0001] This utility model relates to the field of surge protector application technology, specifically an intelligent AC power surge protector. Background Technology
[0002] With the rapid development of electronic information technology, the number of intelligent devices and signaling devices is constantly increasing, and the requirements for the safety and stability of power equipment are becoming increasingly stringent. Especially during the rainy season, surge voltage has a particularly significant impact on electronic information equipment and power systems, which may lead to equipment damage or system failure.
[0003] Surge protectors can limit overvoltage and overcurrent in power systems to a certain extent. They have fast response times and strong current-carrying capacity, and are widely used in low-voltage power distribution systems to suppress induced lightning and industrial surges entering power lines, protecting electrical equipment from overvoltage damage. However, surge protectors have shortcomings in durability and stability. Over long periods of use, they may gradually fail due to frequent surge events, reducing their protective effect. After installation, surge protectors require regular inspection by professionals to ensure they are functioning properly in case of failure or damage. Intelligent AC power surge protectors utilize IoT technology to remotely transmit surge protector data, enabling real-time management and maintenance, reducing manual maintenance costs and improving equipment maintenance and management efficiency.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1-4As shown, this utility model proposes an intelligent AC power surge protector, including a rear housing 1 and a front housing 2. The front end of the front housing 2 is snapped onto the rear housing 1, and the rear housing 1 and the front housing 2 are fixed together by a screw in a screw groove 17 provided on the rear housing 1. The snap-fit connection allows for initial assembly of the two, facilitating subsequent fixing with screws. The combination of snap-fit and screw fixing ensures connection stability and improves assembly efficiency. Fixing with screws in the screw groove 17 further enhances the connection strength between the front housing 2 and the rear housing 1. The design of the screw groove 17 allows the screw to be firmly installed on the rear housing, and tightening the screw makes the connection between the front and rear housings tighter and less prone to loosening. A working indicator light 6 is installed on the middle part of the raised front face of the surge protector's front housing 2. The working indicator light 6 provides a clear display of the operating status to the user. When the surge protector is working normally, the working indicator light 6 will light up; when a fault or abnormality occurs, the working indicator light 6 will turn off, reminding the user to perform timely inspection and maintenance, thereby ensuring the safe and stable operation of the electrical equipment. The rear housing 1 of the surge protector is provided with a snap-fit mounting groove 16. Limiting protrusions 15 are evenly distributed at the upper end of the snap-fit mounting groove 16, and a standard electrical guide rail 20 is snapped onto the limiting protrusions 15. A [missing information - likely a type of rail] is installed at the lower end of the snap-fit mounting groove 16. The design of the fastening clip 18 and the standard electrical guide rail 20 allows the surge protector to be easily fixed to the rear housing 1 of the protector during installation by snapping it on, improving the convenience and efficiency of installation. The setting of the limiting protrusion 15 ensures the stability and firmness of the standard electrical guide rail 20 during the snapping process, avoiding loosening or falling off due to improper installation. The installation of the fastening clip 18 further enhances the fixing effect of the snap-fit mounting groove 16, making the surge protector more stable and reliable after installation, effectively resisting external impacts and vibrations, and ensuring the normal operation and service life of the equipment.
