Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, a video lightning protection device includes a housing 1. The housing 1 is provided with an input terminal 11, an output terminal 12, and a grounding wire 13. The input terminal 11 is connected to an external line, and the output terminal 12 is connected to the protected device. 11 is fixedly connected to the housing 1, and the output end 12 is movably connected to the housing 1. The housing 1 is provided with an adjustment assembly 2 for adjusting the activity of the output end 12. The adjustment assembly 2 makes the horizontal axis of the output end 12 coincide with the input end 11. The horizontal axis is set coaxially, and the housing 1 is provided with a control assembly 3 for controlling the tap length of the grounding wire 13. The adjustment assembly 2 is an eccentric wheel connected to the housing 1 through screw rotation, and the output end 12 is fixedly connected to the On the eccentric wheel, the eccentric wheel is easy...

Abstract

The invention relates to a video lightning protector, comprising a shell. The shell is provided with an input end, an output end and a ground wire. The input end is connected with an external line. The output end is connected to protected equipment. The input end is fixedly connected to the shell. The output end is movably connected to the shell. The shell is provided with an adjusting assembly for adjusting movement of the output end. The adjusting assembly enables a horizontal axis of the output end to be coaxial or non-coaxial with a horizontal axis of the input end. The shell is provided with a control assembly used for controlling the tap-off length of the ground wire. The video lightning protector is advantaged in that the adjusting assembly adjusts movement of the output end on the shell, enables the horizontal axis of the output end to be coaxial or non-coaxial with the horizontal axis of the input end, and enables the output end to adapt to different installation places, so that the working strength of the conventional installation is reduced, the practical performance is good, and the adjustment is convenient; and the control assembly controls the tap-off length of the ground wire, so that the damage of the ground wire is reduced, the grounding effect is ensured, the connection is reliable, the usage effect is good, and the structure is simple.

Description

technical field [0001] The invention relates to a video lightning protection device. Background technique [0002] The video lightning protection device is one of the more commonly used surge protectors, and it is an important embodiment of internal lightning protection. In order to prevent the video device from being subjected to the lightning current induced along the line, it is an additional lightning protection product, while the existing video There are many devices, and the connection structure of each input end is different. Since the output end and input end of the existing lightning protection device are fixedly connected to the shell, due to the limitation of the installation occasion, there is a workload in the installation of the lightning protection device. Big defect, it is necessary to increase the length of the grounding wire to adapt to the installation occasion, but it is not conducive to use, and the reliability is poor. Contents of the invention [00...
