[0035] Reference Figures 1 to 9 As shown, the utility model provides a cable branch box, comprising:

[0036] The box body 1 is provided with a wire inlet hole 13 at the bottom;

[0037] The wire harness locking member 5 is arranged in the wire entry hole 13, and includes a limiting portion 51 and a locking portion 52. The limiting portion 51 is arranged through the wire entry hole 13 and is threadedly connected with the locking portion 52. The wire 53 sequentially passes through the limiting portion 51 and the locking portion 52 and then extends into the box body 1.

[0038] The wire harness assembly 2 is arranged on the side wall of the box body 1 and is vertically arranged relative to the wire inlet hole 13. The wires 53 pass through the wire harness assembly 2 and are connected to the electrical components in the box body 1.

[0039] Specifically, a wire entry hole 13 is provided at the bottom of the box 1, and the wire 53 enters the box 1 from the wire entry hole 13 at the bottom of the box 1 and is connected to the electrical components in the box 1. The wire harness locking member 5 is provided in the wire entry hole 13 to lock the wire 53 to prevent the wire 53 from being accidentally pulled by the outside, causing the wire 53 to be disconnected from the connection end of the electrical component or causing the connection end to be unstable, causing a fire. The wire harness assembly 2 is provided on the side wall of the box 1, and after the wire 53 passes through the wire entry hole 13 at the bottom of the box 1, it passes through the wire harness assembly 2 to be connected to the electrical components in the box 1, so that the lines in the box 1 can be kept neat for subsequent maintenance.

[0040] In some embodiments, Figures 7 to 9 As shown, the bottom diameter of the limiting portion 51 is larger than the main body diameter of the limiting portion 51 , the main body diameter of the limiting portion 51 matches the diameter of the wire entry hole 13 , the main body of the limiting portion 51 passes through the wire entry hole 13 , and the bottom of the limiting portion 51 fits with the bottom of the box body 1 .

[0041] Specifically, Figures 7 to 9 As shown, the bottom diameter of the limiting portion 51 is larger than the main body diameter of the limiting portion 51, and the diameter of the main body of the limiting portion 51 matches the wire entry hole 13. In this way, after the limiting portion 51 is installed in the limiting hole, the bottom of the limiting portion 51 can be attached to the bottom of the box body 1, which can well limit the limiting portion 51 and ensure stable installation of the limit.

[0042] In some embodiments, Figures 7 to 9 As shown, an external thread 512 is disposed on the top of the limiting portion 51 , and an internal thread 522 matching the external thread 512 is disposed on the locking portion 52 .

[0043] Specifically, an external thread 512 is provided at the top of the limiting portion 51, and an internal thread 522 is provided at the bottom of the locking portion 52. In this way, after the limiting portion 51 passes through the wire entry hole 13, the locking portion 52 is threadedly connected to the limiting portion 51 to clamp the wire 53.

[0044] In some embodiments, Figures 7 to 9 As shown, a limiting head 511 is provided in the limiting portion 51, the diameter of the limiting head 511 gradually decreases from top to bottom, and a plurality of notches are provided on the limiting head 511, and a locking head 521 cooperating with the limiting head 511 is provided in the locking portion 52, and the diameter of the locking head 521 gradually decreases from top to bottom.

When the limiting head 511 cooperates with the locking head 521, the inner diameter of the locking head 521 gradually decreases from top to bottom. When the locking part 52 is tightened with the limiting part 51, the locking head 521 will squeeze the limiting head 511, so that the limiting head 511 is gradually locked along with the inner part of the locking head 521, thereby clamping the wire 53. In this way, it can adapt to the installation of wires 53 of various specifications or multiple wires 53. After the wire 53 is clamped, it can be prevented from being accidentally pulled by the outside, causing the wire 53 to be disconnected from the connection end of the electrical device or causing the connection end to be unstable, thereby causing the problem of fire.

[0046] In some embodiments, Figure 8 As shown, a sealing ring 54 is provided between the limiting portion 51 and the electric wire 53 .

[0047] Specifically, Figure 8 As shown, after the wire 53 passes through the limiting portion 51, the locking head 521 squeezes the limiting portion 51 to clamp the wire 53, but there is still a gap between the wire 53 and the limiting portion 51. Therefore, the sealing ring 54 can further seal the wire 53 and the limiting portion 51 to prevent more moisture from entering the box 1.

[0048] In some embodiments, Figures 1 to 3 As shown, the harness assembly 2 includes: a harness box 21 and a plurality of harness hooks 22 arranged in the harness box 21, wherein the plurality of harness hooks 22 are arranged in two rows; the harness box 21 is arranged at the opening of the box body 1, and a wire threading groove 23 is provided on one side of the harness box 21 away from the opening of the box body 1, and the wire 53 passes through the wire threading groove 23 and is connected to the electrical device after bypassing the harness hook 22;

[0050] Specifically, an opening is provided at the bottom of the harness box 21, and the opening faces the bottom of the box body 1, so that the wire 53 can directly enter the harness box 21 after passing through the wire entry hole 13. The harness hook 22 located on the side of the box door 7 of the box body 1 is used to limit the wire 53 going upward, and the harness hook 22 located on the side away from the box door 7 is used to limit the wire 53 that needs to pass through the wire groove 23 (the specific wiring can be seen in FIG. Figure 6 As shown), this facilitates the installation of the wires 53. After the lines are arranged and installed, the box cover 24 can be covered. The box cover 24 can be multiple sections or one section, which is not specifically limited in the present utility model.
