The position-limiting holes 19 may be arranged along the side wall of the waterproof gland 10 in the direction of the position-limiting catch 7. When the position-limiting pin 7 is engaged with the position-limiting groove 12, the position-limiting protrusion 18 of the position-limiting pin 7 can be engaged with the position-limiting hole 19, so that the position-limiting pin 7 cannot be easily separated from the waterproof gland 10 along the opposite direction of the position-limiting groove 12, and the waterproof gland 10 can be stably connected to the sealing protrusion 5. After the limiting protrusion 18 is clamped into the limiting hole 19, if necessary, the waterproof gland 10 and the sealing bump 5 are separated from each other, the limiting protrusion 18 in the limiting hole 19 can be pressed, so that the limiting protrusion 18 is separated from the limiting hole 19, and at the moment, the waterproof gland 10 can be pulled out to separate the waterproof gland 10 and the sealing bump 5 from each other.

In one embodiment of the present invention, as shown in fig. 5, an annular protrusion 20 may be provided at the bottom of the upper cover 13. The annular projection 20 can be snapped into the opening 2 to seal the opening 2 in cooperation with the upper lid 13. The wiring base may also include a second seal 21. The second seal ring 21 may be fitted over the annular protrusion 20. When the annular protrusion 20 is clamped into the opening 2, the second sealing ring 21 can cooperate with the annular protrusion 20 to seal the opening 2. Because the second sealing ring 21 has a certain elasticity, after the second sealing ring 21 is sleeved on the annular protrusion 20 and is clamped into the opening 2, the second sealing ring 21 can be pressed between the annular protrusion 20 and the inner wall of the opening 2, so that the opening 2 can be tightly sealed.

In an embodiment of the present invention, as shown in fig. 5, a locking groove 22 may be provided on a side surface of the upper cover 13. A stopper 23 may be provided at a side of the base housing 1. The stopper 23 can be engaged in the engaging groove 22, so that the upper cover 13 can be fixed to the base housing 1. Because the upper cover 13 can be connected to the base housing 1 by the cooperation of the locking slot 22 and the stopper 23, when the mounting is required, the upper cover 13 can be fixed on the base housing 1 by directly pressing the upper cover 13. When it is desired to separate the cover 13 from the base housing 1, the cover 13 can be removed from the opening 2 by pulling on the edge of the cover 13.

In one embodiment of the present invention, as shown in fig. 2, the diameter of the middle part of the first sealing ring 9 may be smaller than the diameter of the two ends. Because the diameter of the end of the first sealing ring 9 is larger than the diameter of the middle of the first sealing ring 9, the end of the first sealing ring 9 is easier to be clamped into the annular groove 6 and the accommodating groove 11, and the accommodating hole 4 can be better sealed.
