[0037] In the present embodiment, the connection stability of the metal pipe assembly 05 and the connecting assembly 01 in the current assembled pipeline is crucial. However, the existing assembled pipeline has problems in the connection of the metal pipe assembly 05 and the connecting assembly 01, which is manifested as that the connection of the metal pipe assembly 05 and the connecting assembly 01 is not firm. The main reason for this problem is that the connection mode of the metal pipe assembly 05 and the mounting hole 15 may be loose or have a gap due to material differences, insufficient machining accuracy or wear after long-term use, thereby affecting the stability and reliability of the overall structure. Therefore, in order to solve the above problems, the present application provides an assembled pipeline. As shown in Figure 1 、 Figure 2 The assembled pipeline can include a connecting assembly 01, a plug assembly 02, a metal pipe assembly 05, a wire assembly 03 and a protective shell assembly 04.

[0038] As shown in Figure 2 , Figure 3 , the connecting assembly 01 can include a connecting sleeve body 11, a connecting hole 13 and a mounting hole 15. The mounting hole 15 can be arranged at one end of the connecting sleeve body 11, and the mounting hole 15 can facilitate connection with the metal pipe assembly 05. The connecting hole 13 can pass through the connecting sleeve body 11, and the connecting hole 13 can communicate with the mounting hole 15. The plug assembly 02 can include a plug sleeve body 21. The connecting sleeve body 11 can be detachably connected with the plug sleeve body 21. The plug sleeve body 21 can be located on the side of the connecting sleeve body 11 away from the connecting hole 13. After the connecting sleeve body 11 and the plug sleeve body 21 are connected as a whole, an installation cavity can be formed in the area surrounded by the two. At least part of the wire assembly 03 is located in the installation cavity, so that the wire assembly 03 can be effectively prevented from being affected by external environmental factors.

[0039] As shown in Figure 1 , the metal pipe assembly 05 can be tubular, and the outer peripheral side can be threaded. One end of the metal pipe assembly 05 can be detachably connected with the mounting hole 15. Thus, the metal pipe assembly 05 can be connected with the mounting hole 15 of the connecting assembly 01, thereby facilitating the arrangement of the wire assembly 03. Moreover, the metal pipe assembly 05 is bendable, thereby facilitating the laying and installation of the assembled pipeline. At least part of the wire assembly 03 can pass through the lumen of the metal pipe assembly 05. At least part of the wire assembly 03 can pass through the mounting hole 15. The end of the wire assembly 03 away from the metal pipe assembly 05 is detachably connected with the plug sleeve body 21. The end of the wire assembly 03 away from the metal pipe assembly 05 is arranged in the installation cavity. Thus, the wire assembly 03 is located inside the installation cavity and the lumen of the metal pipe assembly 05, so that the wire assembly 03 can be prevented from being affected by the external environment, and the wire assembly 03 can be prevented from being damaged and causing hidden troubles.

[0040] As shown in Figure 4As shown, the protective shell assembly 04 can include an outer protective part 41 and an inner protective part 42.

When the connecting assembly 01, the plug assembly 02, the metal pipe assembly 05 and the wire assembly 03 are connected, the filler used to form the inner protective part 42 can be in a liquid state, and the inner protective part 42 can be injected from the connecting hole 13 of the connecting assembly 01 into the area between the mounting hole 15 and the metal pipe assembly 05. After the injection molding of the inner protective part 42 is completed, the inner protective part 42 can fill the gap between the mounting hole 15 and the metal pipe assembly 05, and the inner protective part 42 can be fixedly connected with the outer protective part 41 through the connecting hole 13, so that the connection between the connecting assembly 01 and the metal pipe assembly 05 is more firm, and the separation of the connecting assembly 01 and the metal pipe assembly 05 is prevented, and the tensile strength, reliability and safety of the assembled pipeline are greatly improved. In addition, foreign matter or water can also be prevented from entering the inside of the metal pipe assembly 05.

The arrangement of the isolation plate 231 can greatly increase the creepage distance between the first wire unit 31, the second wire unit 32 and the third wire unit 33, thereby improving the dielectric strength and insulation of the assembled pipeline, and further improving the safety of the safety assembled pipeline.

[0043] In the embodiment, as shown in Figure 6As shown, the first wire unit 31 can include a first wire 311 and a first copper terminal 312.

The arrangement of the conductive sheet 323 can directly ground the leakage current that may occur in the second wire unit 32, prevent accidents from happening, and thus improve the stability and reliability of the equipment.

[0045] In the embodiment, as shown in Figure 7 The plug assembly 02 can include a first plug 26, a second plug 27 and a third plug 28. The first plug 26, the second plug 27 and the third plug 28 can be fixedly connected with the plug sleeve body 21 away from one end of the metal pipe assembly 05, the first plug 26 can be detachably connected with the first copper terminal 312, the second plug 27 can be detachably connected with the second copper terminal 322, and the third plug 28 can be detachably connected with the third copper terminal 332. In this way, the first plug 26, the second plug 27 and the third plug 28 are respectively located on the outer peripheral side of the first copper terminal 312, the second copper terminal 322 and the third copper terminal 332, which can prevent current leakage and prevent the first copper terminal 312, the second copper terminal 322 and the third copper terminal 332 from being affected by external environmental factors.

The limiting plate 24 can be fixedly connected with the plug sleeve body 21 at the end away from the metal pipe assembly 05. The side of the limiting plate 24 close to the metal pipe assembly 05 can abut against one end of the outer protective portion 41. The limiting plate 24 can prevent the outer protective portion 41 from separating from the connection assembly 01 and the plug assembly 02 during use of the assembled pipeline after the outer protective portion 41 is bonded, thereby further ensuring the integrity and stability of the assembled pipeline.

[0050] In the embodiment, as shown in the drawings, Figure 9 The plug assembly 02 can further include a second buckle 25. One end of the second buckle 25 can be fixedly connected with the limiting plate 24, and the other end can extend away from the metal pipe assembly 05.
