[0009] Beneficial Effects

[0010] The present invention provides a tunnel cable box having the following beneficial effects:

[0011] The tunnel cable box can prevent glue leakage from the glue chamber during glue pouring by cooperating between the glue chamber, the first copper bar and the second copper bar arranged inside the cable box body, and by arranging the glue chamber at the end of each cable protection tube. It can also facilitate the maintenance of the first copper bar and the second copper bar, making the tunnel cable box more convenient to use, and solving the problems of difficult maintenance of the copper bar and easy glue leakage during glue pouring in the glue chamber of the existing tunnel cable box.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1:

[0019] like Figure 1-4 As shown, the present invention provides a tunnel cable box, including a cable box body 1 and a cable box cover 2, the outer surface of the cable box body 1 is fixedly connected with a first connecting part 3 and a second connecting part 5, the interior of the first connecting part 3 is provided with a first mounting hole 4, the interior of the second connecting part 5 is provided with a second mounting hole 6, the outer surface of the cable box body 1 is provided with a cable protection tube 7, the end of the cable protection tube 7 is fixedly connected with a mounting head 8, the interior of the cable box body 1 is provided with a glue chamber 11, a first copper busbar 14 and a second copper busbar 15, the outer surface of the glue chamber 11 is fixedly connected with a mounting connecting plate 12, the interior of the mounting connecting plate 12 is provided with a fourth mounting hole 13.

[0020] Specifically, the first connection part 3 and the second connection part 5 are symmetrically arranged on both sides of the cable box body 1 , and the third connection part 9 is symmetrically arranged on both sides of the cable box cover 2 .

[0021] Specifically, the second connection portion 5 is disposed directly below the third connection portion 9 , and the second mounting hole 6 is disposed directly below the third mounting hole 10 .

[0022] Specifically, the cable protection tube 7 is symmetrically arranged on both sides of the cable box body 1 , and the mounting heads 8 are symmetrically arranged on both ends of the cable protection tube 7 .

[0023] Specifically, the glue chamber 11 is arranged on the inner wall of the cable box body 1 , and the interior of the glue chamber 11 is communicated with the interior of the cable protection tube 7 .

[0024] The working principles and beneficial effects of the above embodiments.

[0025] When in use, the cable is peeled and the steel strip and aluminum sheath are grounded together. If one of the two is available, one is grounded, and if neither is available, no grounding is performed. For cables with shielding layers, the shielding layer is grounded through the first copper bus 14 and the second copper bus 15. If there is no shielding layer, no grounding is performed. The remaining cable core wires are connected to the porcelain terminals through the first copper bus 14 and the second copper bus 15 for wiring. After the wiring is completed, the glue chamber 11 is filled with glue. By setting the glue chamber 11 at the end of each cable protection tube 7, it can prevent the glue chamber 11 from leaking during glue filling, and it can also facilitate the maintenance of the first copper bus 14 and the second copper bus 15. The tunnel cable direction box is made of SMC material, and the box body is produced by a molding machine. When the cable box body 1 and the cable box cover 2 are produced, if missing materials or cracks or rough surfaces are found, they do not meet the requirements and the production parameters need to be adjusted. When installed and used on site, this product mainly plays the role of terminal grounding and cable direction division.
