[0042] A first shielding bracket 1 and a second shielding bracket 2 arranged on the first shielding bracket 1 and electrically connected to the first shielding bracket 1; wherein a shielding space for accommodating the cable 30 of the driving recorder 20 is provided between the first shielding bracket 1 and the second shielding bracket 2, a first conductive layer 3 for abutting against the shielding layer 301 of the cable 30 is provided on the surface opposite to the first shielding bracket 1 and the second shielding bracket 2, a conductive part 5 for electrically connecting to the metal shell 201 of the driving recorder 20 is provided on the first shielding bracket 1, and a second conductive layer 4 for abutting against the shielding layer 301 of the cable 30 is provided on the surface opposite to the first shielding bracket 1.

[0043] Here, it can be understood that a shielding space is provided between the first shielding bracket 1 and the second shielding bracket 2, and the shielding space is used to accommodate the cable 30 of the driving recorder 20, so as to fix the first shielding bracket 1 and the second shielding bracket 2 on the cable 30, and a first conductive layer 3 is provided on the first shielding bracket 1, and the first conductive layer 3 is located on the surface opposite to the first shielding bracket 1 and the second shielding bracket 2, and the first conductive layer 3 is used to abut against the shielding layer 301 of the cable 30 to achieve electrical connection between the first conductive layer 3 and the shielding layer 301, and at the same time, the first conductive layer 3 is electrically connected to the first shielding bracket 1, so as to achieve electrical connection between the shielding layer 301, the first conductive layer 3 and the first shielding bracket 1; similarly, The second shielding bracket 2 is provided with a second conductive layer 4, and the second conductive layer 4 is located on the surface of the second shielding bracket 2 opposite to the first shielding bracket 1.
