[0002] The cable distribution box is a device specially designed for outdoor cable lines, which is mainly used for distribution and transfer of cable lines. Such a device plays an important role in the power distribution network, especially in the railway power distribution network and other occasions requiring flexible cable connection. When a cable line needs to cover a long distance, a large cross-section cable is used as the main cable, and when approaching the load point, the main cable is divided into multiple small cross-section cables through the cable distribution box to supply power in a more economical and efficient way. This reduces the waste of cables and optimizes the use of cables.

Since the wiring mechanism 300 can connect the cable during the connection process, the practicability of the device is improved, and the cable can be connected without trimming during the connection process, thereby improving the connection efficiency of the cable.

[0025] Please refer to Figures 1 to 4The first wiring assembly 310 comprises a first copper bar 311, a supporting column 312, a sliding plate 313, a pressing plate 314 and a driving member, the first copper bar 311 is arranged on the bearing frame 200, the supporting column 312 is arranged on the first copper bar 311, a sliding groove is arranged on the supporting column 312, the sliding plate 313 is slidably connected to the supporting column 312 through the sliding groove, the pressing plate 314 is arranged on one side of the sliding plate 313 close to the first copper bar 311, and the driving member is arranged on the supporting column 312 and used to drive the sliding plate 313 to slide.

[0026] The driving member comprises a supporting frame 315, a driving bolt 316 and a round plate 317, the supporting frame 315 is arranged on the supporting column 312, a first circular hole is arranged on the sliding plate 313, a limiting piece 318 is arranged on the sliding plate 313 and located in the first circular hole, a second circular hole is arranged on the limiting piece 318, the round plate 317 is rotatably connected to the first circular hole and located between the sliding plate 313 and the limiting piece 318, a first threaded hole is arranged on the supporting frame 315, and the driving bolt 316 is threadedly connected to the supporting frame 315 through the first threaded hole and fixedly connected to the round plate 317 through the second circular hole.

[0027] When the port of the cable is not provided with a wiring terminal, i.e., the port of the cable is stripped to form a plurality of wire filaments, the driving bolt 316 is screwed to drive the sliding plate 313 to slide upwards, so that the distance between the pressing plate 314 and the first copper bar 311 is increased, the wire filaments of the cable are arranged between the first copper bar 311 and the pressing plate 314, then the driving bolt 316 is screwed to drive the sliding plate 313 and the pressing plate 314 to move towards the first copper bar 311, so that the pressing plate 314 presses the wire filaments of the cable on the first copper bar 311, and the cable is connected.

[0028] Please refer to Figure 2 The second wiring assembly 320 comprises a second copper bar 321 and a locking bolt 322, the second copper bar 321 is arranged on the bearing frame 200, a second threaded hole is arranged on the second copper bar 321, and the locking bolt 322 is threadedly connected to the second copper bar 321 through the second threaded hole.

[0029] When the port of the cable is provided with a wiring terminal, the locking bolt 322 is screwed off from the second copper bar 321, then the locking bolt 322 is inserted into the wiring terminal, the locking bolt 322 is screwed on the second copper bar 321, and the wiring terminal is pressed on the copper bar, so that the cable provided with the wiring terminal is connected.

[0030] Please refer to Figure 1And Figure 2 The box 100 is rotationally connected with a box door 400, and a handle 500 is arranged on the box door 400.

When the box 100 needs to be fixed, the fixing plate 600 is fixed on the device to be connected by inserting the bolt into the third threaded hole, thereby fixing the box 100. The heat dissipation holes 700 can dissipate heat inside the box 100, thereby reducing the probability of fire due to high temperature inside the box 100.

[0032] The embodiment of the indoor fireproof cable distribution box provided by the application is as follows:

[0033] When the port of the cable is not connected to the terminal, that is, the port of the cable is peeled off to form a plurality of wire filaments, at this time, the drive bolt 316 is twisted to drive the sliding plate 313 to slide upward, so that the distance between the pressing plate 314 and the first copper bar 311 increases. At this time, the wire filaments exposed by the cable are placed between the first copper bar 311 and the pressing plate 314. Then, the drive bolt 316 is twisted to drive the sliding plate 313 and the pressing plate 314 to move towards the first copper bar 311, so that the pressing plate 314 presses the wire filaments of the cable on the first copper bar 311, thereby realizing the connection of the cable. When the port of the cable has a terminal, the locking bolt 322 is unscrewed from the second copper bar 321, then the locking bolt 322 is inserted into the terminal, and the locking bolt 322 is screwed on the second copper bar 321 to press the terminal on the copper bar, thereby realizing the connection of the cable with the terminal.

[0034] The above only describes the preferred embodiments of the application and is not intended to limit the application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application shall be included in the protection scope of the application.
