As shown in fig. 2 to 3, the waterproof junction box in the present embodiment includes a box body 1, an upper cover plate 2, and a waterproof joint 3. Wherein: the box body 1 comprises a rectangular bottom plate, a first side plate 11, a second side plate 12, a third side plate 13 and a fourth side plate 14 which are arranged on four sides of the bottom plate, and the first side plate 11, the second side plate 12, the third side plate 13, the fourth side plate 14 and the bottom plate define a wire harness accommodating space with an upper end opening.
The first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 are respectively provided with a joint mounting hole 15, each joint mounting hole 15 is respectively provided with a waterproof joint 3, and each waterproof joint 3 is respectively provided with two leading-out holes.
The upper cover plate 2 is sealed at the upper end opening of the case 1 to seal the wire harness accommodation space.
The wire harness 200 and the connector 201 thereon are accommodated in the wire harness accommodating space, and the wire harness 200 is branched into four wire harness branches, wherein two opposite-polarity leads of each wire harness branch are respectively led out from two leading-out holes on the corresponding waterproof connector 3.
Since the wire harness 200 and the connector 201 thereon are sealed in the harness accommodation space by the case 1 and the upper cover plate 2, each of the harness branches from which the wire harness 200 is branched is led out through the waterproof connector 3. Therefore, compared with the traditional multi-path wiring mode, the waterproof junction box in the embodiment not only realizes multi-path (up to four paths) wiring, but also realizes sealing waterproof protection on the joints on the wire harness.
As shown in fig. 3, optionally, the waterproof junction box in this embodiment further includes a heat-shrinkable tube 6 matched with the waterproof connector 3, one end of the heat-shrinkable tube 6 is sleeved on the waterproof connector 3, and the wire harness branch led out from the waterproof connector 3 penetrates into the heat-shrinkable tube 6, and the heat-shrinkable tube 6 realizes protection of the wire harness branch.
In order to facilitate the installation and the disassembly of the cover plate 2, as shown in fig. 1, optionally, a first connecting screw hole 16 is formed at a joint between the top ends of the first side plate 11 and the second side plate 12, a joint between the top ends of the second side plate 12 and the third side plate 13, a joint between the top ends of the third side plate 13 and the fourth side plate 14, and a joint between the top ends of the fourth side plate 14 and the first side plate 11.
