Description

Technical Field

[0001] The present invention relates to the technical field of electric wires, and in particular to an electrical pipeline. Background Art

[0002] In recent years, prefabricated electrical quick-install piping has become increasingly popular. With its resistance to strong pressure and stretching, prefabricated electrical quick-install piping can effectively adapt to harsh indoor and outdoor environments. Furthermore, its wiring is much more flexible than pipe wiring, making it more suitable for scenarios requiring complex or irregular wiring.

[0003] Since most assembled electrical quick-install pipelines are multi-core wires, one of which needs to be grounded, and copper wires are used as grounding loops in traditional branch line wiring. All wiring is manually inserted into the wiring protection tube. When threading the wires, the hose is often broken or torn, and the insulation layer of the wire is scratched, leaving certain safety hazards. The cost is relatively high. In the prior art, there is an armored mechanical protection layer directly with a grounding wire to solve this problem. An additional grounding wire is added to be intertwined with the other wire cores and an armored mechanical protection layer is added to the outside of the insulation layer to protect the core wire. However, the different core wires of this structure rub against each other during the wiring process and are prone to wear. In addition, the connection between the armored mechanical protection layer and the grounding wire is not tight, and the conductivity is not smooth, which poses a safety hazard of leakage. In addition, the processing and manufacturing process of the cable is complicated, and the mold needs to be re-opened, which increases the manufacturing cost. Summary of the Invention

[0032] Electrical lines are common routes for transmitting electrical energy in daily life. Due to environmental impacts, their protection is extremely important. In addition to the insulation layer on the outside of the core of the electrical line, an armored mechanical protection layer (i.e., the second connecting component 03) is generally installed on the insulation layer of the core to further protect the core and avoid the risk of leakage caused by damage to the insulation layer. To this end, the armored mechanical protection layer also needs to be connected to the ground wire (i.e., the third core 13). The connection must be tightened to prevent the second connecting component 03 from falling off and enhance the conductive effect, thereby eliminating the safety hazard of leakage.

[0033] This embodiment discloses an electrical pipeline, such as Figure 1 、 Figure 2 As shown, the electrical pipeline may include a first connecting component 02 and a second connecting component 03. The first connecting component 02 is respectively provided at both ends of the second connecting component 03. Figure 3 As shown, the electrical pipeline may further include a core wire assembly 01. The core wire assembly 01 is arranged in the first connecting assembly 02. The core wire assembly 01 may include a first core 11, a second core 12, and a third core 13. The first core 11, the second core 12, and the third core 13 may extend along the same central axis. The first core 11, the second core 12, and the third core 13 may be arranged at intervals. The first core 11 may be a neutral wire, the second core 12 may be a live wire, and the third core 13 may be a ground wire. In other embodiments, the core wire assembly 01 may further include an insulating layer, which completely covers the outer peripheral walls of the first core 11, the second core 12, and the third core 13, so that the first core 11, the second core 12, and the third core 13 can be separated to avoid circuit short circuit and leakage.

[0034] like Figure 5 As shown, the first connecting assembly 02 may include a first sleeve unit 21 and a second sleeve unit 22. The first sleeve unit 21 includes a first connecting sleeve 211 and a second connecting sleeve 212. The first connecting sleeve 211 is in the shape of a tube with both ends open. One end of the second connecting sleeve 212 is fixedly connected to the inner wall of the first connecting sleeve 211, and the other end extends toward the open end close to the first connecting sleeve 211. The outer peripheral wall of the second connecting sleeve 212 is spaced apart from the inner peripheral wall of the first connecting sleeve 211. Figure 4 As shown, the second sleeve unit 22 may include a connecting piece 221 and a third connecting sleeve 222. The third connecting sleeve 222 includes a support portion 2221, a first elastic portion 2222, and a second elastic portion 2223. The first elastic portion 2222, the support portion 2221, and the second elastic portion 2223 are fixedly connected in sequence to surround and form a circular ring. The first elastic portion 2222 and the second elastic portion 2223 are spaced apart to form a circular ring with one side open, which facilitates the expansion and deformation of the first elastic portion 2222 and the second elastic portion 2223. The third connecting sleeve 222 is arranged in the spaced area between the second connecting sleeve 212 and the first connecting sleeve 211. One end of the support portion 2221 is fixedly connected to one end of the connecting piece 221. The inner diameter of the third connecting sleeve 222 gradually decreases from one end close to the connecting piece 221 to the other end. The third connecting sleeve 222 has a conical structure. When it is sleeved on the second connecting sleeve 212, the first elastic part 2222 and the second elastic part 2223 can be squeezed by the second connecting sleeve 212 and deformed and expanded in the direction close to the first connecting sleeve 211, so as to facilitate the connection and tightening of various components.

[0035] like Figure 5As shown, part of the outer circumferential wall of the second connecting component 03 abuts the inner circumferential wall of the first connecting sleeve 211. Part of the inner circumferential wall of the second connecting component 03 abuts the outer circumferential wall of the third connecting sleeve 222. One end of the second connecting component 03 extends into the gap between the first connecting sleeve 211 and the third connecting sleeve 222, and the other end extends in a direction away from the first connecting sleeve 211. The core wire component 01 passes through the internal cavity of the first connecting sleeve 211, the second connecting sleeve 212, and the second connecting component 03 in sequence. The end of the connecting piece 221 away from the support portion 2221 is detachably connected to the third core body 13. In this way, by squeezing and tightening the third connecting sleeve 222, one end of the second connecting component 03 can be connected and tightened to the first connecting component 02. At the same time, the abutment between the third connecting sleeve 222 and the second connecting component 03 can be electrically conductive to the third core body 13 through the connecting piece 221, so that the second connecting component 03 acts as a protective layer to protect the core wire component 01 while avoiding the risk of leakage.

[0036] The electrical pipeline can also include a first state and a second state. In the first state, the outer circumferential wall of the first elastic part 2222 and the outer circumferential wall of the second elastic part 2223 are respectively spaced from the inner circumferential wall of the second connecting component 03. At this time, the first elastic part 2222 and the second elastic part 2223 are not deformed. In the second state, the outer circumferential wall of the first elastic part 2222 and the outer circumferential wall of the second elastic part 2223 are respectively abutted against the inner circumferential wall of the second connecting component 03. At this time, the first elastic part 2222 and the second elastic part 2223 are deformed, squeezing the inner circumferential wall of the second connecting component 03 to a state of interference fit, making the connection between the second connecting component 03 and the first connecting component 02 more secure. At the same time, the abutting surface of the third connecting sleeve 222 and the second connecting component 03 fits to facilitate improving the conductive effect and avoid the safety hazard of leakage. The outer diameter of the third connecting sleeve 222 in the first state is smaller than its outer diameter in the second state.

[0037] In this embodiment, if Figure 6 As shown, the third connecting sleeve 222 may further include a fourth protrusion 2224 and a fifth protrusion 2225. The fourth protrusion 2224 is fixedly connected to the outer wall of the first elastic portion 2222. The fifth protrusion 2225 is fixedly connected to the outer wall of the second elastic portion 2223. By providing the fourth protrusion 2224 and the fifth protrusion 2225, when the first elastic portion 2222 and the second elastic portion 2223 expand and deform, the fourth protrusion 2224 and the fifth protrusion 2225 can further squeeze the inner circumferential wall of the second connecting component 03, thereby enhancing the pre-tightening force between the second connecting component 03 and the third connecting sleeve 222, ensuring a tight connection and smooth electrical conduction between the second connecting component 03 and the third connecting sleeve 222.

[0038] In this embodiment, the fourth protrusion 2224 extends in a spiral shape on the outer wall of the first elastic portion 2222. A plurality of fourth protrusions 2224 are arranged at intervals along the axial direction of the first elastic portion 2222. The fifth protrusion 2225 extends in a spiral shape on the outer wall of the second elastic portion 2223. A plurality of fifth protrusions 2225 are arranged at intervals along the axial direction of the second elastic portion 2223. Figure 5 As shown, the second connecting assembly 03 can include a conduit body 31 and an internal thread groove 33. The internal thread groove 33 is provided on the inner circumferential wall of the conduit body 31. The fourth protrusion 2224 and the fifth protrusion 2225 respectively extend into the internal thread groove 33. This allows the outer circumferential wall of the third connecting sleeve 222 and the inner circumferential wall of the second connecting assembly 03 to be threadedly connected, based on the interference fit. This further secures the connection between the third connecting sleeve 222 and the second connecting assembly 03, prevents the second connecting assembly 03 from falling out, and facilitates the removal or installation of the second connecting assembly 03.

[0039] In this embodiment, if Figure 5 As shown, the second connecting component 03 may further include an external thread groove 32. The external thread groove 32 is provided on the outer peripheral wall of the catheter body 31. The external thread groove 32 and the internal thread groove 33 are alternately arranged in sequence. The first connecting sleeve 211 may include a first sleeve body 2111 and a first protrusion 2112. The first protrusion 2112 is fixedly connected to the inner peripheral wall of the first sleeve body 2111. The first protrusion 2112 extends spirally on the inner peripheral wall of the first sleeve body 2111. The first protrusion 2112 extends into the external thread groove 32. In this way, the outer peripheral wall of the second connecting component 03 can be threadedly connected to the inner peripheral wall of the first connecting sleeve 211, further preventing the second connecting component 03 from loosening and falling off.

[0040] In this embodiment, the second state may further include the fourth protrusion 2224 and the fifth protrusion 2225 respectively abutting against the internal thread groove 33. This can increase the contact area between the third connecting sleeve 222 and the second connecting component 03, facilitate electrical conduction, and make the connection between the third connecting sleeve 222 and the second connecting component 03 more secure, thereby avoiding an excessive gap between the third connecting sleeve 222 and the second connecting component 03, and avoiding the risk of leakage when the third connecting sleeve 222 conducts electricity from the second connecting component 03 to the third core 13.

[0041] In this embodiment, the second state may further include the first protrusion 2112 abutting against the external thread groove 32. This allows the first protrusion 2112 to squeeze the outer circumference of the second connecting component 03, thereby improving the connection and fastening effect between the first connecting component 02 and the second connecting component 03. At the same time, it can also make the inner circumferential wall of the second connecting component 03 fit more closely with the third connecting sleeve 222, thereby improving the conductive effect of the third connecting sleeve 222 and avoiding the potential leakage.

[0042] In this embodiment, the surface roughness of the first protrusion 2112 can be within a set range (i.e., the surface roughness of the first protrusion 2112 can be at least greater than the surface roughness of the external thread groove 32). This increases the friction between the first protrusion 2112 and the external thread groove 32, facilitating the fastening of the second connecting assembly 03 and preventing it from loosening or falling off.

[0043] In this embodiment, the outer diameter of the second connecting sleeve 212 gradually decreases from one end away from the open end of the first connecting sleeve 211 toward the other end. The minimum outer diameter of the second connecting sleeve 212 is greater than the minimum inner diameter of the third connecting sleeve 222 and smaller than the maximum inner diameter of the third connecting sleeve 222. This allows the second connecting sleeve 212 to be more easily inserted into the third connecting sleeve 222, while also expanding and deforming the first elastic portion 2222 and the second elastic portion 2223, facilitating a secure connection between the third connecting sleeve 222 and the second connecting assembly 03 and promoting electrical conduction.

[0044] In this embodiment, if Figure 7 As shown, the second connecting sleeve 212 includes a second sleeve body 2121, a second protrusion 2122, and a third protrusion 2123. The outer diameter of the second sleeve body 2121 gradually decreases from one end away from the open end of the first connecting sleeve 211 to the other end. The minimum outer diameter of the second sleeve body 2121 is greater than the minimum inner diameter of the third connecting sleeve 222 and smaller than the maximum inner diameter of the third connecting sleeve 222. This makes it easier for the second connecting sleeve 212 to be inserted into the third connecting sleeve 222, while at the same time expanding and deforming the first elastic portion 2222 and the second elastic portion 2223, thereby facilitating the fastening and connection between the third connecting sleeve 222 and the second connecting assembly 03 and facilitating electrical conduction. The second protrusion 2122 is fixedly connected to the outer wall of the second sleeve body 2121. The third protrusion 2123 is fixedly connected to the outer wall of the second sleeve body 2121. The second protrusion 2122 and the third protrusion 2123 can further increase the deformation of the first elastic portion 2222 and the second elastic portion 2223 , thereby improving the tensioning effect of the first elastic portion 2222 and the second elastic portion 2223 .

[0045] In this embodiment, if Figure 8As shown, the second protrusion 2122 is provided on the outer wall of the second sleeve 2121 on the side close to the first elastic portion 2222. The third protrusion 2123 is provided on the outer wall of the second sleeve 2121 on the side close to the second elastic portion 2223. The projection of the second protrusion 2122 on the first elastic portion 2222 completely overlaps with the fourth protrusion 2224. The projection of the third protrusion 2123 on the second elastic portion 2223 completely overlaps with the fifth protrusion 2225. This can further enhance the deformation effect of the first elastic portion 2222 and the second elastic portion 2223, facilitate the fastening connection between the third connecting sleeve 222 and the second connecting assembly 03, and because the third connecting sleeve 222 fits tightly with the second connecting assembly 03, its conductive effect can also be enhanced, thereby avoiding the risk of leakage.

[0046] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present disclosure.
