[0008] Preferably, the cable lock sleeve is made of rubber.

[0009] Preferably, the lock sleeve body and the guide hole are in interference fit.

[0010] Preferably, the cover plate and the box body are connected through connecting screws.

[0011] Preferably, a sealing ring is arranged between the cover plate and the box body.

[0012] The utility model discloses an advantageous effect is: the utility model discloses, the cable passes out from the guide hole on the box body, the diameter of the grommet is adjustable, makes the contraction petiole on the close department contract inwards through reducing the diameter of the grommet, and the contraction petiole holds the cable tightly, thereby realizes the fixing of cable, and even if the cable is pulled outward, the cable also can not be pulled out, thereby avoid the cable and high voltage cable distribution box to separate, and further avoid the power supply interruption or arc fault, effectively avoid the fire and other serious accidents.
