Description

Technical Field

[0001] This utility model relates to a busbar trunking, specifically a busbar trunking with a conductive bar isolation fastening insulation structure. Background Technology

[0002] Busbar trunking is an enclosed metal device made of copper or aluminum busbars, primarily used to distribute large amounts of power to various components in a distributed system. It is commonly used in indoor low-voltage power transmission trunk line projects, gradually replacing traditional electrical wires and cables.

[0003] A typical busbar trunking system consists of a housing and conductor bars. The conductor bars are usually installed in the housing. Since busbar trunking systems are used in various complex electrical environments, such as high-rise buildings and industrial plants, collisions and shaking are inevitable during use. This can cause the conductor bars in the busbar trunking to shift, resulting in short circuits caused by contact between the conductor bars. Therefore, the conductor bars are usually coated with insulating material.

[0004] Due to the relatively complex operating environment, the insulation material is prone to aging after prolonged use. The aged insulation material is easy to fall off the busbars. If the exposed busbars come into contact again, a short circuit will still occur. Furthermore, since busbar trunking is usually installed in a sealed manner, it is difficult to monitor the status of each component inside the busbar trunking in real time. Utility Model Content

[0005] The purpose of this invention is to provide a busbar trunking with a conductive bar isolation and fastening insulation structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A busbar trunking with a conductive bar isolation and fastening insulation structure includes a base and a cover; both ends of the base and the cover are equipped with connecting blocks; a connecting plate is installed on the connecting blocks by bolts.

[0008] The base is equipped with partitions; the partitions are evenly distributed to divide the base into multiple conductor chambers;

[0009] The conductor chamber is equipped with multiple fastening structures, and an insulating block is connected to the fastening structure. After the conductive busbar is installed in the conductor chamber, the fastening structure can autonomously drive the insulating block to squeeze the conductive busbar, thereby limiting the displacement of the conductive busbar.

[0010] The busbar trunking with conductive bar partition fastening insulation structure as described above: the fastening structure includes a mounting plate installed on the partition; a hinge rod is mounted on the mounting plate; a rotating plate is rotatably mounted on the hinge rod; a first fixed post is mounted on the hinge rod; a second fixed post is mounted on the rotating plate; the first fixed post and the second fixed post are connected by a tension spring; and an insulating block is mounted on the rotating plate.

[0011] The busbar trunking with conductive busbar isolation and fastening insulation structure as described above: a fixing rod is installed on the connecting plate; multiple sets of second connecting rods are hinged to the fixing rod; multiple sets of second connecting rods are rotatably mounted on the first connecting rod; multiple sets of sleeves that can be fitted onto the conductive busbar are rotatably mounted on the first connecting rod.

[0012] The busbar trunking with conductive bar isolation and fastening insulation structure as described above: the insulating block has multiple sets of grooves to increase the coefficient of friction.

[0013] The busbar trunking with conductive bar partition and fastening insulation structure as described above: the partition plate has a curved section in the center.

[0014] The busbar trunking with conductive bar isolation and fastening insulation structure as described above: the base is equipped with a slot for engaging with the conductive bar.

[0015] The busbar trunking with conductive bar isolation and fastening insulation structure as described above: the surfaces of the partition, the base and the cover are all coated with an insulating coating.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the conductive bars are placed separately in the conductor chamber so that each conductive bar can be installed independently, avoiding electrical accidents caused by contact between the conductive bars due to external interference factors (collision, violent shaking, bending deformation caused by force, etc.) during use; by using symmetrical insulating blocks to abut against both sides of the conductive bars, the displacement of the conductive bars in the conductor chamber is restricted, so that there is no frictional loss between the conductive bars and the base and the partition during use, thereby preventing damage to the insulation layer due to long-term frictional loss, thus avoiding the occurrence of electrical accidents.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] Please see Figures 1-7As an embodiment of this utility model, the busbar trunking with conductive bar isolation fastening insulation structure includes a base 1 and a cover 2; both ends of the base 1 and the cover 2 are equipped with connecting blocks 3; the connecting plate 4 is installed on the connecting blocks 3 by bolts;

[0039] A partition 5 is installed inside the base 1; the partition 5 is evenly distributed to divide the base 1 into multiple wire chambers;

[0040] The conductor chamber is provided with multiple sets of fastening structures, and the fastening structures are connected to insulating blocks 9. After the conductive busbar 13 is installed in the conductor chamber, the fastening structures can autonomously drive the insulating blocks 9 to squeeze the conductive busbar 13 to limit the displacement of the conductive busbar 13.

[0041] In this embodiment, during use, the conductive bars 13 are placed in the conductor chamber so that each conductive bar 13 is installed independently, avoiding electrical accidents caused by contact between the conductive bars 13 due to external interference factors (collision, violent shaking, bending deformation of the conductive bars 13 due to force, etc.) during use.

[0042] Multiple sets of fastening structures are symmetrically installed on the partitions 5 on both sides of the conductor chamber. After the conductor busbar 13 is installed into the conductor chamber, an external force is first applied to the fastening structure so that it drives the insulating block 9 to rotate and approach the conductor busbar 13. After the insulating block 9 rotates past the equilibrium position, the fastening structure will move automatically (without applying external force) to drive the insulating block 9 to rotate so that the insulating block 9 comes into contact with the conductor busbar 13.

[0043] The symmetrical insulating blocks 9 contact the two sides of the conductive busbar 13 respectively, thereby restricting the displacement of the conductive busbar 13 in the conductor chamber. This prevents frictional loss between the conductive busbar 13 and the base 1 and the partition 5 during use, thus preventing damage to the insulation layer due to long-term frictional loss and avoiding electrical accidents.

[0044] After the conductive busbar 13 is fixed in position, the cover 2 and the base 1 are aligned and connected together, and the connecting plate 4 is installed on the connecting block 3 by bolts, so that the cover 2 and the base 1 are installed together. The installation process is relatively simple and can effectively improve the installation efficiency.

[0045] As a further embodiment of this utility model, the fastening structure includes a mounting plate 6 installed on the partition 5; a hinge rod 601 is installed on the mounting plate 6; a rotating plate 7 is rotatably installed on the hinge rod 601; a first fixing post 602 is installed on the hinge rod 601; a second fixing post 701 is installed on the rotating plate 7; the first fixing post 602 and the second fixing post 701 are connected by a tension spring 8; and an insulating block 9 is installed on the rotating plate 7.

[0046] In this embodiment, when the second fixed post 701 is located on the extension line of the line connecting the hinge center of the insulating block 9 and the hinge rod 601 and the first fixed post 602, the insulating block 9 is in a balanced position. In this position, the rotating plate 7 is in a balanced state, that is, the elastic force of the tension spring 8 cannot drive the rotating plate 7 to rotate.

[0047] In the initial state, the included angle between the two symmetrical insulating blocks 9 is the largest, which facilitates the installation of the conductive busbar 13 in the conductor chamber; after the installation is completed, an external force is applied to make the rotating plate 7 rotate, and the second fixed column 701 will rotate synchronously, thereby driving the insulating block 9 to rotate closer to the conductive busbar 13. During this process, the second fixed column 701 will gradually move closer to the equilibrium position, the tension spring 8 is stretched, and the elastic force becomes greater and greater.

[0048] When the second fixed post 701 passes the equilibrium position, the elastic force of the tension spring 8 will cause the second fixed post 701 to rotate. During this process, no external force needs to be applied. At this time, the rotating plate 7 rotates, thereby causing the insulating block 9 to rotate and move closer to the conductive busbar 13 until it comes into close contact with the conductive busbar 13.

[0049] By having symmetrical insulating blocks 9 contacting both sides of the conductive busbar 13, the displacement of the conductive busbar 13 within the conductor chamber is restricted. This prevents frictional loss between the conductive busbar 13, the base 1, and the partition 5 during use, thus preventing damage to the insulation layer due to prolonged frictional loss and avoiding electrical accidents.

[0050] Furthermore, the elastic force of the tension spring 8 will always act on the rotating plate 7, so that the insulating block 9 will always have a tendency to further compress the conductive busbar 13, preventing the fastening structure from losing its restraining effect on the conductive busbar 13 due to external interference factors, thereby improving the stability of the fastening structure.

[0051] As a further embodiment of this utility model, a fixing rod 401 is installed on the connecting plate 4; multiple sets of second connecting rods 12 are hinged to the fixing rod 401; the multiple sets of second connecting rods 12 are rotatably mounted on the first connecting rod 11; multiple sets of sleeves 10 that can be sleeved on the conductive busbar 13 are rotatably mounted on the first connecting rod 11.

[0052] In this embodiment, the exposed portion of the conductive busbar 13 connected to the connecting plate 4 is slidably connected to the sleeve 10. When the exposed portion of one conductive busbar 13 is subjected to external force and bends and deforms, the bending and deformation force will cause the sleeve 10 connected to it to shift. During the shift, the sleeve 10 will rotate and engage with the first connecting rod 11, and drive the first connecting rod 11 to shift synchronously, thereby driving all the sleeves 10 to shift synchronously. At this time, the second connecting rod 12 rotates and engages with the first connecting rod 11 and the fixing rod 401. This causes all the conductive busbars 13 to bend and deform synchronously in one direction, so as to prevent the conductive busbar 13 from contacting another conductive busbar 13 during the bending and deformation process, thereby improving electrical safety and avoiding safety accidents.

[0053] As a further improvement of this utility model, the insulating block 9 has multiple sets of grooves 901 for increasing the coefficient of friction.

[0054] In this embodiment, the groove 901 can increase the friction between the insulating block 9 and the conductive busbar 13, thereby further preventing the conductive busbar 13 from shifting, thus improving the stability of the fastening structure and avoiding safety accidents.

[0055] As a further embodiment of this utility model, a curved portion 501 is provided in the central part of the partition 5.

[0056] In this embodiment, the bending portion 501 is provided so that the conductive busbar 13 has a bent portion after installation. When the conductive busbar 13 is subjected to a force along its length, the conductive busbar 13 tends to extend outward, but cannot move due to the restriction of the fastening mechanism. When the force on the conductive busbar 13 is too large and the fastening structure can no longer limit the displacement, the conductive busbar 13 will extend outward. At this time, the bent portion will provide a buffer to prevent the conductive busbar 13 from being stretched and damaged, thereby improving the stability of the busbar trunking.

[0057] As a further embodiment of this utility model, the base 1 is provided with a slot 101 for engaging with the conductive busbar 13.

[0058] In this embodiment, the slot 101 is used for positioning the conductive busbar 13 during installation, so that when the subsequent fastening structure drives the insulating block 9 to contact the conductive busbar 13, the forces on both sides of the conductive busbar 13 are relatively balanced, and there will be no flipping or displacement, thereby preventing frictional wear during the installation process.

[0059] As a further embodiment of this utility model, the surfaces of the partition 5, the base 1, and the cover 2 are all coated with an insulating coating.

[0060] In this embodiment, the insulating coating effectively prevents leakage, thereby improving the safety of the busbar trunking and preventing electrical accidents during use.

[0061] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
