[0018] As Figures 1-4 The utility model discloses a cable waterproof terminal box, including first casing 10, second casing 20, terminal 30, one side of first casing 10 and one side of second casing 20 are rotatablely connected, terminal 30 and first casing 10 are detachably connected, first casing 10 and second casing 20 are equipped with first chamber 11 and second chamber 21, and first chamber 11 and second chamber 21 fill waterproof gel respectively, and the both ends of first chamber 11 and second chamber 21 are equipped with skirt part 4, when first casing 10 and second casing 20 split, first chamber 11 and second chamber 21 split and form the closed chamber, and the both ends skirt part 4 split and form incoming line port 71 and outgoing line port 72. Waterproof gel is solid soft waterproof glue.

[0019] First casing 10 and second casing 20 are equipped with clamping groove 12 and buckle 22 respectively on the connecting opposite side, when first casing 10 and second casing 20 split, clamping groove 12 and buckle 22 are connected.

[0020] First casing 10 is equipped with stop edge 13 in the position of clamping groove 12, and second casing 20 is equipped with stop slot 23 in the position corresponding to stop edge 13, when first casing 10 and second casing 20 split, waterproof gel overflows outward, stop edge 13 inserts stop slot 23 and forms overflow channel 14, prevents waterproof gel from directly overflowing to the position of clamping groove 12 and buckle 22, guarantees that clamping groove 12 and buckle 22 cooperate smoothly.

[0021] The first housing 10 and the second housing 20 have a pressure ligament 50 on the outer side of the skirt portion 4. The inner wall of the pressure ligament 50 has pressure teeth 51. The pressure ligament 50 has through holes 52 on both the left and right sides.

[0022] When the junction box is closed, the wire clamping ligament 50 can wrap the cable to prevent the cable from shaking. The wire clamping teeth 51 can increase the friction and make the wire clamping ligament 50 wrap more tightly. The through holes 52 on the left and right sides of the wire clamping ligament 50 can be threaded with cable ties to tie the wire clamping ligament 50 and the cable tightly. This prevents the cable from shaking and also prevents the junction box from opening when the buckle 22 of the slot 12 is loose.

[0023] One side of the first housing 10 and one side of the second housing 20 are connected as one unit by a bending portion 6.

[0024] The terminal block 30 has connecting slots 31 on both the left and right sides. Correspondingly, the first chamber 11 has connecting protrusions 15. When the terminal block 30 is installed, the connecting protrusions 15 pass through the connecting slots 31 to connect the terminal block 30 and the first housing 10.

[0025] The waterproof cable junction box has one inlet port 71 and one or more outlet ports 72. In this embodiment, the waterproof cable junction box has two outlet ports 72, which can realize the function of one inlet and two outlets for branching and conducting. More outlet ports 72 can also be provided according to wiring needs.

[0026] In use, first connect the input and output cables through the terminal block 30, then install the terminal block 30 inside the first housing 10, and then assemble the first housing 10 and the second housing 20. During the assembly process, due to the volume of the cable and the terminal block 30, the waterproof gel of the first housing 10 and the second housing 20 fuses together, and at the same time, the excess waterproof gel is squeezed out to the surroundings, thereby sealing the gaps between the first housing 10, the second housing 20 and the cable, achieving a waterproof effect.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Simple modifications and substitutions made by those skilled in the art without departing from the spirit and scope of this utility model are within its protection scope.
