Embodiment 1
[0012] In this embodiment, the Ethernet signal SPD product is taken as an example, from figure 1 It can be seen that the present invention includes a housing 1 and a PCB lightning protection circuit board 4. The housing 1 is divided into left and right parts, which are connected by bolts. The lower part of the housing 1 is provided with an integrated guide rail 2 and an installation card 3. The PCB lightning protection circuit board 4. It is fixed in the housing 1 by screws; the rear-stage lightning protection device TVS transient suppression diode of the lightning protection line and the low-temperature fuse are packaged in parallel in a plastic case cured by epoxy resin to form a signal lightning protection module, and the low-temperature fuse Both ends are connected to remote signal data terminal 5, so that the heat released when the lightning protection device deteriorates is transferred to the low-temperature fuse as much as possible. When the device deteriorates, when the...
Embodiment 2
[0014] This embodiment takes the 2M data (L9) signal lightning arrester product as an example, by figure 2 It can be seen that, different from Embodiment 1, the protection line input interface 13 and the line output interface 14 are 2M data (L9) signal input and output interfaces, and the PCB lightning protection circuit board 4 is a corresponding lightning protection circuit board.
Embodiment 3
[0016] This embodiment takes the video (BNC) signal lightning arrester product as an example, by image 3 It can be seen that the difference between this embodiment and Embodiment 1 is that the line input interface 13 and the line output interface 14 are video (BNC) signal input and output interfaces respectively, and the PCB lightning protection circuit board 4 is a matching lightning protection circuit board.
