The second interface is used for connecting the communication cable of the vehicle so that various communication signals can be transmitted to the communication components of the vehicle through the lightning protection connector. A grounding element is disposed in the second mounting hole. The grounding element is electrically connected to the surge protector connector and is used for grounding cable connection. The surge protector connector includes a connector and a surge protector connected to each other. The mounting base has a first sidewall and a second sidewall on both sides along a first direction. The accommodating cavity is divided by the mounting base to form a first accommodating cavity and a second accommodating cavity. The connector is disposed in the first sidewall and located within the first accommodating cavity. The surge protector is disposed in the second sidewall and located within the second accommodating cavity. Multiple first mounting holes are provided, and the multiple first mounting holes surround the second mounting hole. The surge protector connector is disposed on the first mounting hole. Multiple surge protector connectors are respectively used for surge protection and transmission of reserved radio frequency (RF) signals, multi-band RF signals, wide-band RF signals, and shortwave RF signals. The multiple surge protector connectors include a first connector for receiving reserved RF signals, a second connector for receiving multi-band RF signals, a third connector for receiving wide-band RF signals, and a fourth connector for receiving shortwave RF signals. The surge protector connector also includes a connecting seat, which is mounted on the first mounting hole by fasteners. One end of the connecting seat is connected to the connector, and the other end of the connecting seat is connected to the surge protector tube. The first direction is the length direction of the box body. The bottom walls on both sides of the accommodating cavity have grooves. The grooves are arranged along the first direction. The bottom wall of the groove has a plurality of drainage holes arranged at intervals along the first direction.

2. The feeder box as described in claim 1, characterized in that, The feeder box also includes a connector. The mounting base has a third mounting hole. One end of the connector is fastened to the mounting base through the third mounting hole, and the other end of the connector is installed in the accommodating cavity.

3. The feeder box as described in claim 1, characterized in that, The grounding component includes a connecting section and a fixing section that are connected to each other. The fixing section is disposed on the first side wall and is located within the first accommodating cavity. The connecting section is disposed on the second side wall and is located within the second accommodating cavity. The connecting section is used for connecting grounding cables.

4. The feeder box as described in claim 1, characterized in that, The lid is provided with a first rotating part, and the box body is provided with a second rotating part that matches the first rotating part. The first rotating part is rotatably disposed on the second rotating part so that the lid and the box body can be rotatably connected.

5. The feeder box as described in claim 1, characterized in that, The feeder box further includes a first sealing element and a second sealing element. The box body has an inlet and an outlet, which are respectively connected to the receiving cavity. The inlet is located in the first receiving cavity, and the outlet is located in the second receiving cavity. The first sealing element is detachably disposed at the inlet to seal the inlet. The second sealing element is detachably disposed at the outlet to seal the outlet.

6. The feeder box as described in claim 1, characterized in that, The surge protector includes a housing, a first electrode, and a second electrode.
