[0061] Embodiment 1

[0062] During the laying of power cables, in order to meet the laying requirements of the cables, it is often necessary to connect two cables together. In the prior art, in order to improve the protection of the connection between the two cables, a protection box is installed at the connection between the two cables. Specifically, the cable is passed through the protection box, and the connection between the two cables is located inside the protection box. However, the sealing effect of the existing protection box is poor, which may easily cause rainwater, mosquitoes or other foreign objects to enter the protection box and damage the cables, resulting in unnecessary losses and increasing production costs. In addition, in actual application, it is inevitable that the cables will be pulled. The connection strength of the two cables connected together is low, which may easily lead to the problem of disconnection of the two cables connected together.

The locking assembly 200 can lock and fix the cable to the cavity wall of the passage cavity 250.

[0064] The cable joint protection device is installed and fixed to the iron tower by setting a mounting frame 400, and the accommodating box 100 for accommodating the cable joint is installed on the mounting frame 400, so that the cable joint and the iron tower can be installed and fixed. By opening two through-holes 113 that are connected to the accommodating cavity 116 on the accommodating box 100, the joints of the two cables can be respectively extended into the accommodating cavity 116 along the through-holes 113, so that the accommodating box 100 can be opened and closed. By facilitating the connection and fixing of the two cable joints in the accommodating cavity 116, the gap between the through-holes 113 and the cable is blocked by using the sealing component 300, so that when the accommodating box 100 is closed, The accommodating cavity 116 is used to seal and accommodate the cable connector, thereby improving the protection of the cable connector. By arranging a locking assembly 200 on the mounting frame 400 and opening a penetration cavity 250 on the locking assembly 200, the cable connector is passed through the penetration cavity 250 and the penetration opening 113 in sequence to reach the accommodating cavity 116, and the cable is locked and fixed to the cavity wall of the penetration cavity 250. On the premise that the connectors of the two cables are connected to each other, the two cables can be locked, thereby improving the structural strength of the connection between the two cables, solving the problem of disconnection at the connection between the two cables when the cables are pulled after being connected together, avoiding repeated connection of the two cables, and improving work efficiency.

By setting a through gap 114 on the side wall of the box body 110 where the through opening 113 is provided, the through gap 114 penetrates the through opening 113 in the radial direction of the through opening 113, and the first elastic sealing ring 310 is passed through the through gap 114 along the axial direction of the through opening 113, so that the outer peripheral wall of the first elastic sealing ring 310 abuts against the inner cavity wall of the through opening 113, and in combination with the cable passing through the inner cavity of the first elastic sealing ring 310, the first abutting member 320 and the second abutting member 330 in the through gap 114 are respectively abutted against the inner cavity wall of the first elastic sealing ring 310 and the cable along the two opposite ends of the first elastic sealing ring 310, so that the first elastic sealing ring 310 can fully block the gap between the first through opening 113 and the cable.

[0071] In addition, in order to further improve the abutment effect of the first abutment member 320 and the second abutment member 330 on the first elastic sealing ring 310, a first matching groove 321 is provided at one end of the first abutment member 320 close to the first elastic sealing ring 310, and a second matching groove 331 is provided at one end of the second abutment member 330 close to the first elastic sealing ring 310. The area jointly enclosed by the first matching groove 321 and the second matching groove 331 has the same radial cross-sectional shape as the first elastic sealing ring 310, so that the first abutment member 320 and the second abutment member 330 can be tightly abutted against the circumferential inner cavity wall of the first elastic sealing ring 310 and the cable, thereby achieving sufficient abutment between the inner cavity wall of the first elastic sealing ring 310 and the cable, thereby improving the sealing effect.

[0074] In this embodiment, if Figure 5 As shown, the second abutment member 330 is fixed to the cover plate 120. When the cover plate 120 is fixed to the box body 110, the second abutment member 330 can be fixed to the box body 110. Therefore, there is no need to set an additional mounting hole on the second abutment member 330 to be fixed to the box body 110, simplifying the structure of the second abutment member 330.

[0075] As an optional solution, the sealing assembly 300 further includes a second elastic sealing ring (not shown in the figure), which is sandwiched between the box body 110 and the cover plate 120. By sandwiching the second elastic sealing ring between the box body 110 and the cover plate 120, the second elastic sealing ring can block the gap between the box body 110 and the cover plate 120 to further ensure the sealing of the accommodating cavity 116.

There is a snap-in gap between two adjacent snap-in protrusions 112, and the snap-in gap is used to snap-in and fix the connector of the cable. By providing at least two snap-in protrusions 112 arranged at intervals along a preset direction in the accommodating cavity 116 of the box body 110, and using the snap-in gap between two adjacent snap-in protrusions 112 to snap-in and fix the connector of the cable, the snap-in and fixation of the cable connector in the accommodating cavity 116 can be achieved, and the cable connector can be prevented from moving arbitrarily in the accommodating cavity 116, thereby improving the protection of the cable connector. It should be noted that in this embodiment, the preset direction is the left-right direction. The specific number of the clamping protrusions 112 is determined by the number of cable cores in the cable, and each cable core is clamped and fixed in a clamping gap. In this embodiment, the cable has 23 cable cores, so 24 clamping protrusions 112 extending in the left-right direction are provided in the accommodating cavity 116, and the 24 clamping protrusions 112 extending in the left-right direction together form 23 clamping gaps. In other embodiments, the specific direction of the preset direction and the number of the clamping protrusions 112 can also be adjusted arbitrarily according to actual needs, and this embodiment does not make specific limitations.
