[0028] The cable accessory quick grounding assembly of the present invention includes a seal and a conductive connector 6, which is sleeved on the second sheath 4 so that the seal is sealed and connected to the conductive shell 1 and the second sheath 4 at the same time, thereby preventing external water vapor from entering the cable body in the sheath component and preventing the insulation degree of the cable from being reduced; at the same time, the conductive connector 6 is used to achieve electrical connection between the first sheath 3 and the conductive shell 1, thereby achieving electrical connection between the sheath component and the conductive shell 1 without the need to inject lead-tin alloy, and achieving a sealed connection between the sheath component and the conductive shell 1, thereby solving the problem of poor sealing of the cable metal sheath in the prior art, reducing the difficulty of grounding the sheath component of the cable, shortening the grounding time of the sheath component of the cable, and allowing inexperienced installers to operate.

[0029] Specifically (not shown in the figure), there are two seals, one of which is sleeved on the first sheath 3, so that the seal is sealed and connected to the conductive shell 1 and the first sheath 3 at the same time, further preventing external water vapor from entering the cable in the sheath component.

[0030] Specifically, the conductive housing 1 may be a copper shell of a cable connector or a tail pipe of a cable terminal.

[0031] Specifically, to ensure the external insulation of the copper shell of the cable connector, it is necessary to first wrap the filling tape 51 between the exposed metal part of the copper shell end and the second sheath 4, and then install the heat shrink tube 52 to restore the insulation layer 53 outside the copper shell.

[0032] Specifically, the cable includes a sheath component and a cable body, and the sheath component is sleeved on the cable body.

[0033] In this embodiment, the seal is a wedge-shaped sealing ring 7, which has an outer ring bevel 8 and an inner ring surface 9 relatively arranged along the radial direction of the second sleeve 4.
