Description

Technical Field

[0001] The invention relates to the technical field of electrical pipelines, and in particular to an assembled flat pipeline with a built-in grounding device. Background Art

[0002] Electrical pipelines are pipes or channels used to accommodate, protect and guide wires in line systems established for power transmission. Prefabricated electrical pipelines have the functions of resisting strong pressure and stretching, can effectively adapt to harsh indoor and outdoor environments, and the wiring is much more flexible than pipeline wiring. Since most prefabricated electrical pipelines are multi-core wires, not only the core wires need to be grounded, but the metal pipes themselves also need to be grounded for safe use. In China, traditional branch line wiring uses copper wires as grounding loops, and all wiring is manually inserted into the wiring protection tube. When threading, the hose is often broken, cracked, and the insulation layer of the wire is scratched, leaving certain safety hazards, and the cost is relatively high. Due to the limited length of a single electrical pipeline, multiple electrical pipelines are often required to be connected in series to meet the use requirements. Two electrical pipelines need to be connected through a connector. Since both the electrical pipeline and the connector are made of wear-resistant metal to protect the internal wires, considering the safety of electricity use, they must be tightly connected to the ground wire, which also makes the installation of the connector cumbersome and affects the installation efficiency.

In addition, in addition to being used to indicate an orientation or position relationship, some of the above terms may also be used to indicate other meanings, such as the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to the specific circumstances.

Unless otherwise specified, "plurality" means two or more.

[0029] In this embodiment, when the wires are in an environment that is prone to physical impact and friction, such as in some industrial plants where a large number of machines and equipment are in operation, the wires may be collided with by vehicles transporting materials, moving robotic arms, etc. The metal conduit 11 can play a protective role, preventing the insulation layer of the wires from being scratched or worn, and preventing the internal wires from being exposed and causing faults such as short circuits. For the sake of electrical safety, the metal conduit 11 requires a grounding wire 14. Due to the limited length of the metal conduit 11, it is often necessary to connect multiple metal conduits 11 through joints, which results in a more cumbersome installation process and lower efficiency. To this end, this embodiment discloses a flat pipeline. As Figure 1 As shown, the assembled flat pipeline with a built-in grounding device includes: a wiring harness assembly 10 and a connector assembly 20.

[0030] The wiring harness assembly 10 includes a metal conduit 11, a first wire 12, a second wire 13 and a ground wire 14. The first wire 12, the second wire 13 and the ground wire 14 are inserted into the metal conduit 11. The material of the metal conduit 11 can be a wear-resistant metal, such as a steel pipe, a galvanized pipe, etc. It can better protect the first wire 12, the second wire 13, and the ground wire 14, and has good fireproof, moisture-proof and shielding properties. In other embodiments, the wiring harness assembly 10 can be other types of wires, such as single-core, double-core, multi-core, etc.

[0031] like Figure 3 As shown, at least one end of the wiring harness assembly 10 is detachably connected to a connector assembly 20. The connector assembly 20 includes a conductive connector unit 21, a shell unit 22, and a conductive grounding unit 23. The conductive connector unit 21 is connected to the shell unit 22, and the connection method can be a detachable connection or a fixed connection. The conductive connector unit 21 is located outside the shell unit 22. The conductive grounding unit 23 is located inside the shell unit 22. One end of the first wire 12, the second wire 13, and the ground wire 14 is inserted into the shell unit 22. The first wire 12, the second wire 13, and the ground wire 14 are electrically connected to the conductive connector unit 21, respectively. The ground wire 14 is detachably connected to the metal conduit 11 through the conductive grounding unit 23.

[0032] Among them, Figure 4 As shown, the conductive grounding unit 23 includes a conductive sheet 231, a conductive connecting plate 232 and two conductive abutting plates 233. One end of the conductive sheet 231 is electrically connected to the metal conduit 11, and the other end is electrically connected to the conductive connecting plate 232. The conductive connecting plate 232 and the conductive abutting plate 233 are both arc-shaped. The axis of the conductive connecting plate 232 is parallel to the axis of the conductive abutting plate 233. The two conductive abutting plates 233 are distributed at both ends of the conductive connecting plate 232. The conductive connecting plate 232 and the conductive abutting plate 233 are fixedly connected.

[0033] When the conductive grounding unit 23 and the ground wire 14 are locked with each other, the ground wire 14 is clamped between the two conductive abutment plates 233. The conductive connecting plate 232 and the conductive abutment plate 233 are both elastic. The two parts of the conductive connecting plate 232 connected to the conductive abutment plate 233 tend to move closer to each other. The concave side of the conductive abutment plate 233 faces the ground wire 14, and the end of the conductive abutment plate 233 away from the conductive connecting plate 232 tends to move closer to the conductive connecting plate 232.

[0034] Through the above arrangement, the metal conduit 11 is engaged with the ground wire 14 through the conductive grounding unit 23 to achieve grounding electrical connection, thereby ensuring electrical safety and improving installation efficiency.

[0035] In this embodiment, if Figure 4As shown, the curvature radius of the conductive connecting plate 232 is smaller than the curvature radius of the conductive abutting plate 233. There is a gap between the conductive connecting plate 232 and the ground wire 14. The conductive abutting plate 233 is tightly fitted against the ground wire 14. Through the above arrangement, the curvature degree of the arc curve of the conductive connecting plate 232 is relatively large, so that the conductive abutting plate 233 has a greater abutment force on the ground wire 14, ensuring that the conductive abutting plate 233 always maintains abutment with the ground wire 14, ensuring the safety of electricity use.

[0036] In this embodiment, if Figure 4 As shown, the thickness of the conductive connecting plate 232 is greater than the thickness of the conductive abutting plate 233. Thus, the conductive connecting plate 232 has a strong elastic force. Since there is a gap between the conductive connecting plate 232 and the ground wire 14, the strong elastic force of the conductive connecting plate 232 acts entirely on the conductive abutting plate 233, so that the conductive abutting plate 233 increases the abutting force on the ground wire 14, further avoiding the ground wire 14 from falling off or loosening due to elastic failure or too little elastic force, thereby ensuring the safety of electricity use.

[0037] In this embodiment, if Figure 4 As shown, the conductive grounding unit 23 also includes two outer flaps 234. The outer flaps 234 correspond to the conductive abutment plates 233 one by one. The outer flaps 234 are fixedly connected to the corresponding conductive abutment plates 233. The outer flaps 234 are located on the side of the conductive abutment plates 233 away from the conductive connection plates 232. The outer flaps 234 are folded and extended toward the outer peripheral side of the conductive abutment plates 233. The folding and extension of the outer flaps 234 play a guiding effect, making it easier for the ground wire 14 to be inserted into the conductive grounding unit 23, thereby improving the installation efficiency.

[0038] In this embodiment, if Figure 4As shown, the connector assembly 20 also includes a limit unit 24. The limit unit 24 is fixedly connected to the shell unit 22. The limit unit 24 is located inside the shell unit 22. There are two groups of limit units 24, and the ground wire 14 is located between the two groups of limit units 24. The outer flap 234 corresponds to the limit unit 24 one by one. One end of the outer flap 234 away from the conductive abutment plate 233 abuts against the limit unit 24. By abutting one end of the outer flap 234 with the limit unit 24, the conductive abutment plate 233 is further tightened in the direction close to the ground wire 14, thereby increasing the clamping force of the conductive abutment plate 233 on the ground wire 14, preventing the ground wire 14 from falling off, and ensuring the safety of electricity use. In addition, when the outer flap 234 is clamped between the two limiting units 24, the outer flap 234 is folded and extended toward the limiting unit 24. Therefore, at the moment when the end of the outer flap 234 away from the conductive abutting plate 233 abuts the limiting unit 24, the reaction force of the limiting unit 24 on the outer flap 234 makes it possible for the two outer flaps 234 to be folded further away from the ground wire 14. Since the elastic force of the conductive connecting plate 232 is relatively strong and fully acts on the two conductive abutting plates 233, the conductive abutting plates 233 transmit the elastic force to the outer flap 234, thereby preventing the two outer flaps 234 from further folding outwards and causing looseness. Therefore, in the process of the conductive grounding unit 23 of this embodiment being clamped on the ground wire 14, not only can the guidance of the outer flap 234 make it easy for the ground wire 14 to be clamped between the two conductive abutment plates 233, but also the two outer flaps 234 can be tightly closed and not easily flipped open at the initial moment of clamping, and the clamping degree of the two conductive abutment plates 233 on the ground wire 14 is guaranteed.

[0039] In this embodiment, if Figure 4 As shown, the thickness of the conductive abutment plate 233 is less than that of the outer flap 234. With this arrangement, the outer flap 234 can provide better support, and the limiting unit 24 has a limiting effect on the outer flap 234, so that the two outer flaps 234 can have a certain degree of folding effect. Since the thickness of the outer flap 234 is greater than that of the conductive abutment plate 233, the conductive abutment plate 233 can be more easily driven to undergo elastic deformation during the folding process of the outer flap 234, thereby increasing the contact area between the conductive abutment plate 233 and the ground wire 14, thereby further improving the abutment effect of the two conductive abutment plates 233 on the ground wire 14.

[0040] In this embodiment, if Figure 2 , Figure 5 , Figure 6As shown, the shell unit 22 includes a first half shell 221 and a second half shell 222. The first half shell 221 is connected to the second half shell 222, and the connection method can be a detachable connection or a fixed connection. The first half shell 221 and the second half shell 222 are open on the sides facing each other. The inner cavity of the first half shell 221 and the inner cavity of the second half shell 222 are combined to form the inner cavity of the shell unit 22. The limiting unit 24 is fixedly connected to the first half shell 221. Such a split arrangement can facilitate the production of the shell unit 22 and the assembly of the wiring harness assembly 10, thereby improving the installation efficiency.

[0041] In other embodiments, a fixing sleeve may be provided on the outer peripheral side of the shell unit 22, so that the connection between the first half shell 221 and the second half shell 222 can be firmly established. At the same time, foreign matter can be prevented from entering through the gap between the first half shell 221 and the second half shell 222, thereby improving the sealing of the shell unit 22.

[0042] In this embodiment, if Figure 4 As shown, the limiting unit 24 includes a limiting block 241 and a guiding slope 242. The limiting block 241 is provided with a guiding slope 242 at one end away from the first half shell 221. The guiding slope 242 is arranged toward the ground wire 14. By providing the guiding slope 242, the outer flap 234 of the conductive grounding unit 23 is more easily engaged with the setting position of the limiting block 241 through the guiding effect of the guiding slope 242, so as to improve the installation efficiency.

[0043] In this embodiment, if Figure 4 , Figure 5 , Figure 6 As shown, the joint assembly 20 also includes a locking unit 25. The locking unit 25 includes a first elastic plate 251 and a second elastic plate 252. One end of the first elastic plate 251 is fixedly connected to the first half shell 221. One end of the second elastic plate 252 is fixedly connected to the second half shell 222. Two first elastic plates 251 are arranged opposite to each other. Two second elastic plates 252 are arranged opposite to each other. The first elastic plates 251 and the second elastic plates 252 correspond to each other one by one.

[0044] When the first half shell 221 and the second half shell 222 are locked by the locking unit 25, the two facing sides of the two first elastic plates 251 respectively abut against their corresponding second elastic plates 252, and the two second elastic plates 252 tend to move away from each other, while the two first elastic plates 251 tend to move toward each other.

[0045] Through the above arrangement, the first half shell 221 and the second half shell 222 are locked to ensure a stable connection, avoid excessive gap between the first half shell 221 and the second half shell 222 to cause foreign matter to enter the interior, and ensure the sealing of the shell unit 22 to ensure electrical safety.

[0046] In other embodiments, Figure 4 As shown, a guide slope 253 is provided at one end of the first elastic plate 251 away from the first half shell 221, and the guide slope 253 is arranged toward the ground wire 14. The guide slope 253 can guide the first elastic plate 251 to be more easily sleeved on the outer side of the second elastic plate 252, thereby improving installation efficiency.

[0047] In this embodiment, if Figure 4 As shown, when the first half shell 221 and the second half shell 222 are locked by the locking unit 25, the side of the second elastic plate 252 facing away from the first elastic plate 251 is in contact with the conductive abutting plate 233. This makes the elastic force of the first elastic plate 251 to shrink greater than the elastic force of the second elastic plate 252 to expand, so that during the installation of the connector assembly 20, the second elastic plate 252 gradually approaches the conductive abutting plate 233 by relying on the elastic force of the first elastic plate 251 and finally abuts against the conductive abutting plate 233, further enhancing the abutting force of the conductive abutting plate 233 on the ground wire 14.

[0048] In other embodiments, the second elastic plates 252 have a tendency to move closer to each other due to their own elasticity. However, in this case, when the second half shell is installed, the second elastic plates 252 rub against the outer surface of the abutment plate, causing significant wear on the outer surface of the abutment plate, which is not conducive to the stability of the grounding structure. In serious cases, the abutment force on the second elastic plates 252 may damage the thinner abutment plate.

[0049] Therefore, the second elastic plate 252 is configured to have a tendency to move away from each other by relying on its own elasticity, so that during the clamping process of the first half shell and the second half shell, a gap is retained between the second elastic plate 252 and the conductive abutment plate 233 without long-distance wear, and the conductive abutment plate 233 can be pressed tightly only at the moment when the final clamping is completed. In this way, excessive friction between the second elastic plate 252 and the thinner surface of the conductive abutment plate 233 causing wear of the conductive abutment plate 233 is avoided as much as possible, thereby improving the service life of the conductive abutment plate 233.

[0050] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
