Description

Technical Field

[0001] The utility model relates to the technical field of cable branch boxes, in particular to an outdoor rainproof cable branch box. Background Art

[0002] When the cable branch box is used on rainy days, rainwater will still seep into the box, causing problems such as component damage or wiring short circuit.

[0006] Preferably, a docking slope is provided at the bottom of the movable door, and the inclination angle of the docking slope is the same as the inclination angle of the drainage board.

[0007] Preferably, the external baffle completely covers the vent hole at the front end of the vent hole.

[0008] Preferably, the blocking frame is at the rear end of the vent hole and the height of the frame body is higher than the height of the vent hole, and the bottom end of the guiding arc surface inside the blocking frame is connected to the outside through the vent hole.

[0009] Preferably, the movable door is movably connected to the external box body through an external hinge, the side panels of the movable door are completely inserted into the docking grooves, and the side panels and the sleeve frame are sealed with each other when the movable door is closed.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The utility model provides an outdoor rainproof cable branch box, which seals the movable door and the external box body and shields the rear of the ventilation holes without affecting the sealing of the movable door to the external box body and the ventilation holes, thereby effectively preventing splashing rainwater from entering the external box body through the gaps and the ventilation holes, and maintaining the normal operation of internal components.

[0019] Furthermore, a docking slope 21 is provided at the bottom of the movable door 2 , and the inclination angle of the docking slope 21 is the same as the inclination angle of the drain plate 6 , so that the movable door 2 will not be blocked by the drain plate 6 when closed.

[0020] Furthermore, the external baffle 3 completely covers the vent hole 8 at the front end of the vent hole 8 , and the external baffle 3 blocks the outside of the vent hole 8 .

[0021] Furthermore, the blocking frame 7 is at the rear end of the vent 8 and the height of its frame is higher than the height of the vent 8. The bottom end of the guiding arc surface 71 inside the blocking frame 7 is connected to the outside through the vent 8, and the interior of the external box 1 is ventilated through the vent 8.

[0022] Furthermore, the movable door 2 is movably connected to the external box body 1 through an external hinge, the side panel of the movable door 2 is completely inserted into the docking groove 5, and the side panel of the movable door 2 and the sleeve frame 4 are sealed with each other when the movable door 2 is closed. The hinge for connection is arranged on the outside of the movable door 2, which is conducive to forming a seal between the movable door 2 and the external box body 1.

[0023] Working principle: The utility model is an outdoor rainproof cable branch box. On rainy days, rainwater penetrates into the interior through the gap between the movable door 2 and the external box body 1, and the side plate of the movable door 2 is stuck in the docking groove 5. The penetrated rainwater is blocked by the sleeve frame 4, and the rainwater flows downward and is guided out of the interior of the external box body 1 by the drainage plate 6. When the rainfall is heavy and splashes toward the vent 8, the external baffle 3 partially blocks the splashing rainwater, and the other part of the splashing rainwater is blocked by the blocking frame 7, and the rainwater flows to the outside along the guiding arc surface 71 and is discharged from the vent 8, preventing the rainwater from entering the external box body 1.
