Combined surge protector aimed at high-speed transmission rate

The utility model discloses a combined surge protector aimed at high-speed transmission rate. The combined surge protector comprises a housing and side walls connected with the housing. The housing is provided with a power module, a control module, and a video module inside. The housing is provided with a baffle which divides the housing into two independent cavities. The inner side wall of the housing is provided with at least two guide rails. Four top ends of the housing are provided with slot holes. The power module and the control module are connected with a circuit board. The power module and the control module are fixed in the first cavity of the housing through the guide rails on the side walls. The video module is connected with the circuit board and is fixed in the second cavity in the housing through the guide rails on the side wall of the housing. The width of the second cavity is matched with the width of the circuit board connected with the video module. The video module is disposed in the independent cavity. When lightning stroke occurs, the combined surge protector can effectively prevent interference of large current flowing through the power module on the video module, so as to prevent videos from being hazy or prevent abnormity from occurring, and ensuring normal operation of video acquisition.
