Description

Technical Field

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

[0002] In recent years, assembled electrical quick-install pipelines have been increasingly widely used. Assembled electrical quick-install pipelines have the functions of resisting strong pressure and tensile stress, can effectively adapt to harsh indoor and outdoor environments, and the wiring is much more flexible than pipeline wiring, and is more suitable for scenarios that require complex or irregular wiring.

[0003] Since most of the assembled electrical quick-install pipelines are multi-core wires, one of which needs to be grounded. In traditional branch wiring, copper wires are used as the grounding circuit, and all the wiring is manually inserted into the wiring protection pipe. During the wiring process, the flexible hose is often broken or cracked, and the insulating layer of the wire is scratched, leaving certain safety hazards and relatively high construction costs. There is a solution in the prior art that uses an armored mechanical protection layer directly with a grounding wire. For example, "CN211264983U, an integrated interlocking armored aluminum conductor grounding armored wire" and "CN2476915Y, a hot wire cable". The above two types of cables use an additional grounding wire to be intertwined with other cores and add an armored mechanical protection layer outside the insulating layer to protect the cores. However, the different cores of this structure rub against each other during the wiring process, are prone to wear, and cannot achieve stable connection and easy installation. Moreover, it cannot be cut into the required length of the pipeline on site according to the needs of the construction party. The connection between the armored mechanical protection layer and the grounding wire is not firm, the conductivity is not smooth, there is a safety hazard of electric leakage, and the manufacturing process of the cable is complex, requiring re-opening of the mold, increasing the manufacturing cost.

[0028] As a common line for transmitting electric energy in daily life, due to environmental impacts, the protection of prefabricated electrical pipelines is extremely important. In addition to setting an insulating layer outside the core of the prefabricated electrical pipeline, generally, an armored mechanical protection layer (i.e., the second connection component 03) needs to be sleeved on the insulating layer of the core to further protect the core and avoid the leakage danger caused by the damage of the insulating layer. For this reason, the armored mechanical protection layer also needs to be connected to the grounding wire (i.e., the third core 13), and the connection part needs to be firmly connected to avoid the detachment of the second connection component 03 and enhance the conductive effect, thereby eliminating the potential safety hazard of electric leakage.

[0029] This embodiment discloses an assembled electrical pipeline. As Figure 1 , Figure 2 shown, the assembled electrical pipeline may include a first connection component 02 and a second connection component 03. The first connection component 02 is respectively arranged at both ends of the second connection component 03. As Figure 3 shown, the assembled electrical pipeline may further include a core wire component 01. The core wire component 01 is arranged inside the first connection component 02. The core wire component 01 may include a first core body 11, a second core body 12, and a third core body 13. The first core body 11, the second core body 12, and the third core body 13 may extend along the same central axis. The first core body 11, the second core body 12, and the third core body 13 may be arranged at intervals. The first core body 11 may be a neutral wire, the second core body 12 may be a live wire, and the third core body 13 may be a ground wire. In some other embodiments, the core wire component 01 may further include an insulating layer, and the insulating layer completely covers the outer peripheral walls of the first core body 11, the second core body 12, and the third core body 13, so as to separate the first core body 11, the second core body 12, and the third core body 13 at intervals and avoid short circuits and electric leakage of the circuit.

[0030] As Figure 3 shown, the first connection component 02 includes a first sleeve unit 21, a second sleeve unit 22, and a third sleeve unit 23. The first sleeve unit 21 includes a first connection sleeve 211 and a second connection sleeve 212. The inner peripheral wall of the first connection sleeve 211 is spaced from the outer peripheral wall of the second connection sleeve 212. The second sleeve unit 22 includes a third connection sleeve 221 and a fourth connection sleeve 222. One end of the third connection sleeve 221 extends into the spaced area between the first connection sleeve 211 and the second connection sleeve 212. A part of the outer peripheral wall of the third connection sleeve 221 is detachably connected to the first connection sleeve 211. A part of the inner peripheral wall of the third connection sleeve 221 is detachably connected to the second connection sleeve 212. The outer peripheral wall of the fourth connection sleeve 222 is spaced from the inner peripheral wall of the third connection sleeve 221. One end of the fourth connection sleeve 222 is fixedly connected to a part of the inner peripheral wall of the third connection sleeve 221 away from the second connection sleeve 212, and the other end extends in the direction away from the second connection sleeve 212. As Figure 4 shown, the third sleeve unit 23 may include a connecting piece 231 and a fifth connection sleeve 232. The fifth connection sleeve 232 is arranged in the spaced area between the third connection sleeve 221 and the fourth connection sleeve 222. One end of the fifth connection sleeve 232 is fixedly connected to one end of the connecting piece 231. The fifth connection sleeve 232 is provided with an opening. The inner diameter of the fifth connection sleeve 232 gradually decreases from the end close to the connecting piece 231 to the other end, and the fifth connection sleeve 232 has a conical structure. When it is sleeved on the fourth connection sleeve 222, it can be squeezed by the fourth connection sleeve 222 and deformed and expanded in the direction close to the first connection sleeve 211, facilitating the fastening connection of each component.

[0031] As shown Figure 4 in the figure, a part of the outer peripheral wall of the second connection component 03 can be in contact with the inner peripheral wall of the third connection sleeve 221. A part of the inner peripheral wall of the second connection component 03 can be in contact with the outer peripheral wall of the fifth connection sleeve 232. One end of the second connection component 03 extends into the interval area between the third connection sleeve 221 and the fifth connection sleeve 232, and the other end extends in a direction away from the third connection sleeve 221. The core wire assembly 01 sequentially passes through the inner cavity of the second connection sleeve 212, the third connection sleeve 221, the fourth connection sleeve 222, and the second connection component 03. One end of the connecting piece 231 away from the fifth connection sleeve 232 is detachably connected to the third core body 13. In this way, through the extrusion and expansion of the fifth connection sleeve 232, one end of the second connection component 03 can be tightly connected to the first connection component 02. At the same time, the contact part between the fifth connection sleeve 232 and the second connection component 03 can conduct electricity to the third core body 13 through the connecting piece 231, so that while the second connection component 03 serves as a protective layer to protect the core wire assembly 01, the hidden danger of electric leakage can be avoided.

[0032] In this embodiment, as Figure 5 shown in the figure, the fifth connection sleeve 232 can include a support portion 2321, a first elastic portion 2322, and a second elastic portion 2323. The first elastic portion 2322, the support portion 2321, and the second elastic portion 2323 are fixedly connected in sequence to surround and form a ring. The first elastic portion 2322 and the second elastic portion 2323 are arranged at intervals, thus forming a ring with one side open, which is convenient for the first elastic portion 2322 and the second elastic portion 2323 to expand and deform.

[0033] In this embodiment, the assembled electrical pipeline can also include a first state and a second state. The first state can include that the outer peripheral walls of the first elastic portion 2322 and the second elastic portion 2323 are respectively arranged at intervals from the inner peripheral wall of the second connection component 03. At this time, the first elastic portion 2322 and the second elastic portion 2323 do not deform. The second state can include that the outer peripheral walls of the first elastic portion 2322 and the second elastic portion 2323 are respectively in contact with the inner peripheral wall of the second connection component 03. At this time, the first elastic portion 2322 and the second elastic portion 2323 deform, squeezing the inner peripheral wall of the second connection component 03 to an interference fit state, making the connection between the second connection component 03 and the first connection component 02 tighter. At the same time, the contact surface between the fifth connection sleeve 232 and the second connection component 03 fits well to improve the conductive effect and avoid the hidden danger of electric leakage safety. The outer diameter of the fifth connection sleeve 232 in the first state is smaller than its outer diameter in the second state.

[0034] In this embodiment, as Figure 4As shown, the second connection component 03 may include a catheter body 31, an internal thread groove 33, and an external thread groove 32. The internal thread groove 33 is provided on the inner peripheral wall of the catheter body 31. 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 at intervals in sequence. The third connection sleeve 221 includes a third sleeve body 2211 and a third thread 2212. The third thread 2212 is fixedly connected to the inner peripheral wall of the third sleeve body 2211. The third thread 2212 extends spirally on the inner peripheral wall of the third sleeve body 2211. The second state further includes the third thread 2212 abutting against the external thread groove 32. This can enable the outer peripheral wall of the second connection component 03 to be threadedly connected to the inner peripheral wall of the first connection sleeve 211, further preventing the second connection component 03 from loosening and falling off. At the same time, the third thread 2212 can squeeze the outer peripheral side of the second connection component 03, improving the connection fastening effect between the first connection component 02 and the second connection component 03. At the same time, it can also make the inner peripheral wall of the second connection component 03 fit more closely with the fifth connection sleeve 232, facilitating the improvement of the conductive effect of the fifth connection sleeve 232 and avoiding potential leakage hazards.

[0035] In this embodiment, the surface roughness of the third thread 2212 can be within a set range (that is, the surface roughness of the third thread 2212 can be at least greater than the surface roughness of the external thread groove 32). This increases the frictional force between the third thread 2212 and the external thread groove 32, facilitating the firm connection of the second connection component 03 and preventing it from loosening and falling off.

[0036] In this embodiment, the outer diameter of the fourth connection sleeve 222 can gradually decrease from one end close to the connection piece 231 to the other end. The minimum outer diameter of the fourth connection sleeve 222 can be greater than the minimum inner diameter of the fifth connection sleeve 232 and less than the maximum inner diameter of the fifth connection sleeve 232. This enables the fourth connection sleeve 222 to be more easily inserted into the fifth connection sleeve 232. At the same time, the first elastic part 2322 and the second elastic part 2323 can be expanded and deformed, facilitating the firm connection between the fifth connection sleeve 232 and the second connection component 03, facilitating conductive grounding, and avoiding potential leakage hazards.

[0037] In this embodiment, as Figure 3 、 Figure 4As shown, the first connection component 02 may further include a connection unit 24. The connection unit 24 may include a terminal bracket 241, a first connector 242, a second connector 243, and a third connector 244. The first connector 242, the second connector 243, and the third connector 244 may extend along the same central axis. The first connector 242, the second connector 243, and the third connector 244 may be circumferentially spaced along the terminal bracket 241. The outer peripheral side of the terminal bracket 241 abuts against the inner peripheral walls of the second connection sleeve 212 and the third connection sleeve 221 respectively. The first core 11, the second core 12, and the third core 13 are respectively embedded in the first connector 242, the second connector 243, and the third connector 244. This can enable the terminal bracket 241 to separate the first connector 242, the second connector 243, and the third connector 244 so that they do not interfere with each other and avoid potential leakage hazards. At the same time, the ends of the first connector 242, the second connector 243, and the third connector 244 away from the core wire assembly 01 can also be quickly connected to external components, facilitating the rapid installation of the assembled electrical pipeline.

[0038] In this embodiment, as Figure 3 , Figure 4 shown, the connection unit 24 may further include a connection bolt 245. One end of the connection bolt 245 sequentially passes through the third connection sleeve 221, the second connection sleeve 212, the connection piece 231, and the third connector 244 until it abuts against the terminal bracket 241. By means of the connection bolt 245, bolt connection can be achieved between the third connection sleeve 221, the second connection sleeve 212, the connection piece 231, and the third connector 244, further tightening the connection between the third connection sleeve 221, the second connection sleeve 212, the connection piece 231, and the third connector 244. While avoiding component detachment, it facilitates the connection piece 231 to conduct electricity to the ground to avoid potential leakage hazards.

[0039] In this embodiment, as Figure 3 , Figure 4 shown, the second connection sleeve 212 may include a second sleeve body 2121 and a second engaging portion 2122. The second engaging portion 2122 is provided at one end of the second sleeve body 2121. The second sleeve body 2121 is engaged and connected to the inner peripheral wall of the third connection sleeve 221 through the second engaging portion 2122. This can improve the connection tightening effect between the second connection sleeve 212 and the third connection sleeve 221 while achieving rapid assembly and avoid detachment.

[0040] In this embodiment, as Figure 3 , Figure 4As shown, the first connecting sleeve 211 may include a first sleeve body 2111, a first thread 2112, and a first engaging portion 2113. The first thread 2112 is fixedly connected to the inner peripheral wall of the first sleeve body 2111. The first thread 2112 spirally extends on the inner peripheral wall of the first sleeve body 2111. The first thread 2112 is spaced from the outer peripheral wall of the second sleeve body 2121. The first engaging portion 2113 is provided at one end of the first sleeve body 2111 away from the first thread 2112. The first sleeve body 2111 is snap-fitted to the outer peripheral wall of the third connecting sleeve 221 through the first engaging portion 2113. In this way, the first connecting assembly 02 can be threadedly connected to an external component through the first thread 2112 of the first connecting sleeve 211, facilitating rapid assembly with the external component. When the length dimension of the core wire assembly 01 of the prefabricated electrical pipeline is insufficient, other core wire assemblies 01 can be connected through the first connecting sleeve 211 to meet the usage requirements.

[0041] In some other embodiments, a limiting portion may be provided on the outer peripheral wall of the third connecting sleeve 221. The limiting portion may be a wedge-shaped block. The limiting portion may be provided adjacent to the first engaging portion 2113. When the first sleeve body 2111 comes off, the limiting portion can prevent the first sleeve body 2111 from moving in the direction close to the second connecting assembly 03.

[0042] Those of ordinary skill in the art can understand that the above embodiments are specific cases for implementing the present disclosure, and in practical applications, various changes can be made in form and details without departing from the spirit and scope of the present disclosure.
