Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology, specifically to a surge protector with 485 communication. Background Technology

[0002] With the development of smart grids and industrial automation, surge protectors integrating 485 communication functions have become key equipment, capable of both suppressing lightning surges and transmitting operational status data in real time. In existing technologies, the 485 communication module is used for status detection via microswitches, but its assembly often relies on screw fixation, resulting in limited operating space, inconvenient operation, low production efficiency, and increased labor costs. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the existing microswitches, which have narrow operating space and low production efficiency, and thus provide a surge protector with 485 communication that is quick and easy to assemble.

[0004] Therefore, this utility model provides a surge protector with 485 communication, comprising: a base having a mounting cavity for mounting a micro switch, wherein at least one positioning post is provided on the inner wall of the mounting cavity, and elastic fasteners are respectively disposed on both sides of the positioning post, the positioning post being adapted to the positioning hole of the micro switch, the elastic fastener having an elastic arm arranged parallel to the positioning post, and a buckle provided at the end of the elastic arm, the elastic arm being located on the side of the micro switch, and the buckle abutting against the rear end face of the micro switch along the insertion direction of the positioning post.

[0005] It also includes a linkage rod that can be moved up and down on the base. The linkage rod includes a main rod, a top rod, and a pressure rod. The top rod is located at the top of the main rod and extends upward. The top rod is used to abut against the tripping rod of the surge protection module. The pressure rod is located on the side of the main rod and extends horizontally. The pressure rod is used to abut against the lever of the micro switch.

[0006] The top surface of the top rod is an arc surface.

[0007] The connection between the pressure rod and the main rod is provided with a reinforcing rib.

[0008] The base is formed with a groove for the main rod to slide up and down, and a side opening located on the side of the groove, the side opening for the pressure rod to extend out.

[0009] The technical solution of this utility model has the following advantages: 1. The surge protector with 485 communication provided by this utility model has a base with a mounting cavity for installing a micro switch. The inner wall of the mounting cavity is provided with at least one positioning post and elastic fasteners on both sides of the positioning post. The positioning post is adapted to the positioning hole of the micro switch. The elastic fastener has an elastic arm arranged parallel to the positioning post and a buckle at the end of the elastic arm. The elastic arm is located on the side of the micro switch. During assembly, after the positioning hole of the micro switch is aligned with the positioning post and inserted, the buckle of the elastic fastener abuts against the rear end face of the micro switch along the insertion direction of the positioning post, thereby preventing the micro switch from separating from the positioning post. Compared with the prior art of fixing with screws, this assembly is quick and convenient, improves disassembly and assembly efficiency, and reduces production costs.

[0010] 2. The surge protector with 485 communication provided by this utility model has a linkage rod including a main rod, a top rod, and a pressure rod. When a lightning overvoltage occurs, the trip rod of the surge protection module will drive the linkage rod to move, which in turn drives the lever of the micro switch to move, thereby issuing a status indication through the 485 module. The linkage rod has the advantage of simple structure. Attached Figure Description
