Description

Technical Field

[0001] This utility model relates to the field of electrical cable equipment technology, and in particular to an electrical equipment connection cable with a junction box. Background Technology

[0002] In the field of electrical cable equipment technology, monitoring the current of electrical equipment connection cables is crucial to ensuring the safe operation of equipment. However, current common equipment connection cables used for current measurement still have shortcomings: most existing electrical equipment connection cables have a relatively simple structure, usually consisting of a single cable with plugs and sockets directly connected at both ends. Traditional cables typically wrap the neutral, live, and ground wires within a unified outer insulation layer. Because the neutral, live, and ground wires are fixed within this unified outer insulation layer, testing or maintaining a single wire often requires breaking through the entire outer insulation layer. Therefore, it is not possible to flexibly measure the current of a single wire. For example, it is difficult to measure the current of a single wire to determine if it is overloaded. At the same time, the measurement of the current difference between multiple wires is also limited by the fixed structure, thus affecting the accuracy of the measurement. Utility Model Content

The interchangeable design of the plug 1 and socket 2 increases the versatility of the device, making it suitable for various regions worldwide and for various types of electrical equipment.

[0023] Furthermore, as a preferred embodiment, the portion of cable 4 located inside junction box 3 has its outer insulation removed, while the remaining portion has an outer insulation.

[0024] Furthermore, as a preferred embodiment, the portion of cable 4 located within junction box 3 includes a neutral wire, a live wire, and a ground wire, which are arranged parallel to each other and stacked vertically.

[0025] Furthermore, in a preferred embodiment, the junction box 3 includes: a top cover 31, a housing 32, and wire boxes 33. The top cover 31 is snapped into the housing 32. Three wire boxes 33 are arranged sequentially from top to bottom inside the housing 32, with the neutral wire, live wire, and ground wire each housed in a corresponding wire box 33. Further, the number of wire boxes 33 can be adjusted according to actual needs. In this embodiment, three wire boxes 33 are set, respectively housing the neutral wire, live wire, and ground wire. However, in some special cases, the number of wire boxes 33 can be reduced. For example, for some devices that only need to monitor the current of the neutral and live wires, the number of wire boxes 33 can be set to two, with one wire box 33 for housing the neutral or live wire and the other wire box 33 for housing the other two wires.

[0026] Furthermore, in a preferred embodiment, a guide ring 321 and a first rotating shaft 322 are disposed inside the housing 32. The first rotating shaft 322 is connected to the bottom wall of the housing 32. The wire box 33 located on the lower side is rotatably connected to the first rotating shaft 322, and two adjacent wire boxes 33 are rotatably connected to each other. The guide ring 321 is disposed inside the housing 32, and all wire boxes 33 are in contact with the guide ring 321. Furthermore, the guide ring 321 can provide stable guidance for the wire box 33 during rotation, ensuring smooth rotation and preventing deviation from the predetermined position.

[0027] Furthermore, in a preferred embodiment, the interior of the junction box 33 has an annular boss 331, and an annular groove is formed between the side wall of the junction box 33 and the annular boss 331. The neutral wire, live wire, and ground wire are all disposed in the corresponding annular groove. Furthermore, the neutral wire, live wire, and ground wire are all arranged around the annular boss 331. The annular boss 331 and the annular groove can be used to prevent the neutral wire, live wire, and ground wire from moving arbitrarily within the corresponding junction box 33.

[0028] Furthermore, in a preferred embodiment, the wire box 33 has a connecting lug, with a mounting hole in the center of the connecting lug. A bearing 332 and a second rotating shaft 333 are disposed in the mounting hole. The first rotating shaft 322 passes through the bearing 332 inside the lower wire box 33, and adjacent wire boxes 33 cooperate with each other through the second rotating shaft 333 and the bearing 332. Further, see... Figure 2 As shown, the lower wire box 33 and the middle wire box 33, as well as the middle wire box 33 and the upper wire box 33, are rotatably connected by a second rotating shaft 333. The second rotating shaft 333 on the lower wire box 33 passes through the bearing 332 inside the middle wire box 33, and the second rotating shaft 333 on the middle wire box 33 passes through the bearing 332 inside the upper wire box 33.

[0029] Furthermore, in a preferred embodiment, an opening 323 is provided on one side of the housing 32, one end of the guide ring is connected to the side wall of one end of the opening 323, and a first rotating shaft 322 is disposed on the bottom wall of the other end of the opening 323, allowing the wire box 33 to rotate within the opening 323. Furthermore, by providing the opening 323, the operator can easily pull out or push back the wire box 33.

[0030] The basic principle of this utility model is as follows: When in use, the plug 1 can be connected to an external charging socket, and the socket 2 can be connected to an external electrical device. When the electrical device is powered on and started, the wire box 33 can be manually rotated so that the wire box 33 rotates in the opening 323 and extends out of the housing 32. Then, an external detection device can be used to detect the wires in the wire box 33.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
