[0002] A network lightning arrester, also known as a surge protector, is a device installed at the device port for protecting against various lightning currents and overvoltages. It is installed at the front end of devices such as network servers, routers, network switches, HUBs, information terminals, and wireless networks to prevent device damage caused by surges on the network line. Currently, the commonly used ones are mostly two-in-one lightning arresters. The circuit board inside this kind of lightning arrester is a rigid PCB board, which cannot be bent, resulting in a relatively large size of the lightning arrester. There are certain limitations in installation when used in some outdoor equipment boxes. At the same time, the existing lightning arresters are all fixed by bolts, which is not convenient for disassembly and assembly during maintenance. Therefore, this application proposes a small network lightning arrester. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Embodiment

[0020] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a small network lightning arrester, including a housing 1. A front baffle 2 is detachably connected inside the housing 1. An arc plate 3 is fixedly connected to one side of the front baffle 2. An FPC board 5 is fixedly connected to the outer surface of the arc plate 3. By using the arc plate 3 in cooperation with the FPC board 5 to replace the traditional rigid PCB board, the space required for installing electronic components can be reduced, the volume of the device can be reduced without affecting the use function, and then the space required for its installation can be reduced. A fixing component 14 for fixing the front baffle 2 is provided above the housing 1;

[0021] The fixing component 14 includes an installation box 141. The installation box 141 is fixed on the top of the housing 1. A fixing plate 142 is slidably connected inside the installation box 141. A spring 143 is fixedly connected between the top of the fixing plate 142 and the inner wall of the installation box 141. Two connecting rods 144 are symmetrically and slidably connected inside the installation box 141. The tops of the two connecting rods 144 penetrate through the installation box 141 and are fixedly connected with a pull ring 145. By changing the position of the fixing plate 142 to engage or disengage with the front baffle 2, the installation and disassembly of the lightning arrester can be realized, and the lightning arrester can be disassembled and assembled without tools, which is convenient for overhauling the lightning arrester and is beneficial to improving the flexibility of disassembly and assembly.

[0022] Further, a rear baffle 4 is fixedly connected to the side of the arc plate 3 away from the front baffle 2. Network interfaces 6 and power terminals 7 are installed on both the front baffle 2 and the rear baffle 4. An indicator light 8 is arranged inside the front baffle 2. The working state of the device can be observed through the indicator light 8. The circuit is protected by electronic components such as inductors, varistors, and fuses, and the network is protected by electronic components such as self - resetting fuses and discharge tubes, thereby ensuring the safety of the use of electronic devices.

[0023] Further, a base 9 is detachably connected to the bottom of the housing 1. A plurality of installation holes 10 are equidistantly opened inside the base 9. Two T - shaped chutes 11 are opened inside the base 9. Two T - shaped sliders 12 are fixedly connected to the bottom of the housing 1. The two T - shaped sliders 12 slide inside the corresponding T - shaped chutes 11. The housing 1 and the base 9 are set as a modular combination, which is convenient for loading and unloading the housing 1. When installing in a narrow space, only the base 9 needs to be installed first, which is convenient for the staff to operate.

[0024] Further, a plurality of fins 13 are symmetrically and fixedly connected to the outside of the housing 1. The fins 13 can assist in the heat dissipation of the device and accelerate the heat dissipation effect of the device.

[0025] Further, two positioning holes 15 are formed inside the front baffle 2, and the bottom end of the fixing plate 142 extends into the positioning holes 15, which is convenient for the cooperation with the fixing plate 142, and then the fixing of the front baffle 2 is completed.

[0026] In summary: When using this device, first install the base 9 inside the equipment box, and then insert the T-shaped slider 12 on the housing 1 into the T-shaped chute 11 inside the base 9 to complete the installation of the device. Insert the network cable and power cable into the network interface 6 and power terminal 7 respectively, and connect the grounding wire. The working state of the device can be observed through the indicator light 8. The circuit is protected by electronic components such as inductors, varistors, and fuses. The network is protected by electronic components such as self-resetting fuses and discharge tubes. The fins 13 can assist in the heat dissipation of the device and accelerate the heat dissipation effect. When internal equipment needs to be maintained, remove the housing 1 from the base 9, pull up the pull ring 145. At this time, the pull ring 145 drives the fixing plate 142 to move upward and compress the spring 143 in cooperation with the connecting rod 144. When the fixing plate 142 is removed from the positioning holes 15, the front baffle 2 can be pulled out from the housing 1, and then the arc-shaped plate 3, FPC board 5, and rear baffle 4 can be taken out from the housing 1. At this time, maintenance can be carried out. When installing, first insert the rear baffle 4 into the housing 1. When the front baffle 2 enters the housing 1, the positioning holes 15 inside it are directly below the fixing plate 142. Under the action of the spring 143, the fixing plate 142 can be pressed into the positioning holes 15 to complete the fixation.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
