Description

Technical Field

[0001] This invention relates to the field of aluminum alloy compact busbar technology, specifically to dustproof aluminum alloy compact busbar. Background Technology

[0002] Busbar trunking is a closed power transmission device that uses copper or aluminum as conductors, is enclosed in a metal shell, and is supported by insulating materials. Among them, aluminum alloy high-density busbar trunking is a power transmission device with an aluminum alloy shell and densely arranged conductors, widely used in data centers, large commercial plazas, high-rise buildings, stadiums, industrial plants, hospitals, and other places.

[0003] Busbar trunking mainly consists of conductors, insulating materials, a housing, and connectors. The conductors are located inside the housing, while the connectors are located at the ends of the conductors and the housing to work with the insulating materials to connect the various sections of the busbar trunking, ensuring the reliability of the electrical connection and enabling the busbar trunking to form a complete power transmission system.

[0004] During use, the connectors of a busbar trunking are exposed to the air. Over time, dust accumulates on the conductor surface or connection points, increasing contact resistance and causing overheating, thus affecting the transmission efficiency and stability of the busbar trunking. Chinese Patent No. CN202222064569.7 describes a dustproof busbar trunking, comprising: a busbar trunking body with a first sliding groove at one end and a second sliding groove at the other end; a first dustproof cover located outside the first sliding groove, with a sliding plate on the outside of the first dustproof cover, a pusher block at one end of the sliding plate, a positioning groove inside the first dustproof cover, and a spring inside the first dustproof cover. The bottom of the spring is fixedly connected to a base plate, and the upper end of the base plate is fixedly connected to a transmission plate. A clamping plate is fixedly connected to the inner side of one end of the transmission plate. In use, the first dustproof cover and the second dustproof cover in the proposed dustproof busbar trunking can provide dust protection for the connection points of the busbar trunking body.

[0005] The aforementioned patent uses a dust cover to protect the connection points of the busbar trunking from dust. However, this dust cover is a rigid shell. During use, heat accumulates inside the shell at the connector and exchanges heat with the outside environment through the shell. Over time, dust inevitably accumulates on the shell surface, reducing its thermal conductivity and affecting heat dissipation from the connector. Furthermore, the shell and busbar trunking are fixed together by the busbar trunking as a single guide rail, making it difficult to disassemble and replace if damaged. This is not conducive to long-term dust protection for the connectors at the busbar trunking. Summary of the Invention

[0006] To address the aforementioned issues, a dustproof aluminum alloy high-density busbar trunking is provided. By adding a corrugated and detachable heat dissipation mesh to the first dustproof plate, the overall heat dissipation area of ​​the dustproof heat conduction component is increased, improving the heat dissipation effect at the connector. At the same time, the corrugated structure forces the airflow to change its trajectory, creating turbulent airflow, which reduces the probability of impurity deposition from the source and prevents dust from clogging the mesh. Furthermore, the dustproof heat conduction component is detachable, so only the damaged board needs to be replaced after damage, without the need for complete replacement.

[0007] To address the problems of the prior art, the present invention provides a dustproof aluminum alloy compact busbar trunking, including a busbar trunking body, wherein the busbar trunking body includes a connector disposed at its end;

[0008] It also includes a dustproof and heat-conducting component disposed at the end of the bus trunking body for dustproof protection of the connector, and the outer side of the bus trunking body is provided with multiple grooves;

[0009] The dustproof and heat-conducting assembly includes two first dustproof plates located on the upper and lower sides of the connector, and two second dustproof plates located on the left and right sides of the connector;

[0010] Each of the first dustproof plates has a vertically penetrating mounting groove, and a heat dissipation mesh is horizontally arranged in the mounting groove, and the heat dissipation mesh is wavy.

[0011] Preferably, an installation frame is provided on the outer side of the heat dissipation mesh, an installation block is fixedly provided on the back of the first dustproof plate, and a threaded pin is also provided on the back of the first dustproof plate. Both the installation block and the installation frame are provided with threaded grooves that cooperate with the threaded pin.

[0012] Preferably, each of the two first dustproof plates is provided with a positioning block on one side where they are installed opposite each other, and the top and bottom of the two second dustproof plates are provided with positioning grooves that cooperate with the positioning blocks.

[0013] Preferably, the second dustproof plate is further provided with a slot, and a connecting block and a threaded positioning pin are provided on the back of the second dustproof plate, and an auxiliary door is rotatably provided in the slot.

[0014] Preferably, the end of the auxiliary door extends outward and is provided with a fixing block, and both the connecting block and the fixing block are provided with threaded holes for use with threaded positioning pins.

[0015] Preferably, a support block is provided on the outer side of the mounting frame, which is horizontally arranged with the first dustproof plate, and the side of the support block near the connector contacts the back of the first dustproof plate.

[0016] Preferably, the mounting frame extends a protective awning on the side away from the connector, and the protective awning is flared.

[0017] Preferably, both ends of the two first dustproof plates are provided with connecting portions extending along the direction of the connector, and fastening bolts are provided at the connecting portions. The first dustproof plates are fixedly connected to the busbar body by the fastening bolts.

[0018] Preferably, both ends of the two second dustproof plates are provided with extensions along the direction of the connector, and the extensions and the connecting parts are both located in the grooves on the outside of the busbar trunking body.

[0019] The advantages of this invention compared to the prior art are:

[0020] 1. A wavy heat dissipation mesh is installed on the first dustproof plate, which increases the overall heat dissipation area of ​​the dustproof heat conduction component and improves the heat dissipation effect at the connector. At the same time, the wavy structure forces the airflow to change its trajectory, forming turbulent airflow, which reduces the probability of impurity deposition from the source and avoids dust clogging the mesh.

[0021] 2. The heat dissipation mesh is installed on the first dustproof plate by the threaded pin and the mounting block through the mounting frame, which is convenient for disassembly and cleaning. After disassembly, the staff can directly inspect the connector through the mounting slot.

[0022] 3. The dustproof and heat-conducting components are designed to be detachable. If damaged, only the damaged part of the board needs to be replaced; there is no need to replace the entire assembly. Attached Figure Description

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] See Figure 1 As shown, the dustproof aluminum alloy compact busbar trunking includes a busbar trunking body 1, and the busbar trunking body 1 includes a connector 1a disposed at its end.

[0032] It should be noted that when using this device, the operator needs to clean the connector 1a first, and then connect the busbars through the connector.

[0033] See Figure 1-3 As shown, it also includes a dustproof and heat-conducting component 2 disposed at the end of the bus trunking body 1 for dustproof protection of the connector 1a, and the outer side of the bus trunking body 1 is provided with multiple grooves.

[0034] The dustproof and heat-conducting assembly 2 includes two first dustproof plates 2a located on the upper and lower sides of the connector 1a, and two second dustproof plates 2b located on the left and right sides of the connector 1a.

[0035] It should be noted that the dustproof and heat-conducting component 2 is installed at the connector 1a. Its purpose is to prevent dust from accumulating on the surface or connection point of the connector 1a after the connection is completed, so as to avoid the accumulation of dust in the air on the surface or connection point of the connector 1a after long-term use, which would increase the contact resistance and cause heat generation, thus affecting the transmission efficiency and stability of the bus trunking body 1.

[0036] See Figure 3-5 As shown, each of the first dustproof plates 2a has a vertically penetrating mounting groove, and a heat dissipation mesh 2a1 is horizontally arranged in the mounting groove, and the heat dissipation mesh 2a1 is wavy.

[0037] It should be noted that the wavy heat dissipation mesh 2a1 increases the overall heat dissipation area of ​​the dustproof heat conduction component and improves the heat dissipation effect at the connector 1a. At the same time, the wavy structure forces the airflow to change its trajectory, forming turbulent airflow, which reduces the probability of impurity deposition from the source and avoids dust clogging the mesh.

[0038] See Figure 4 and Figure 5 As shown, a mounting frame 2a2 is provided on the outer side of the heat dissipation mesh 2a1, a mounting block 2a3 is fixedly provided on the back of the first dustproof plate 2a, and a threaded pin 2a4 is also provided on the back of the first dustproof plate 2a. Threaded grooves that cooperate with the threaded pin 2a4 are opened in both the mounting block 2a3 and the mounting frame 2a2.

[0039] It should be noted that when installing the heat dissipation mesh 2a1, it is placed in the mounting groove by the mounting frame 2a2, and the installation of the heat dissipation mesh 2a1 is completed by the threaded pin 2a4 engaging with the mounting block 2a3 and the threaded groove inside the mounting block 2a3 and the mounting frame 2a2.

[0040] Similarly, during disassembly, rotate the threaded pin 2a4 until it disengages from the threaded groove inside the mounting frame 2a2 to remove the heat dissipation mesh 2a1.

[0041] See Figure 4 As shown, each of the two first dustproof plates 2a is provided with a positioning block 2a5 on one side of the two plates installed opposite each other, and the top and bottom of the two second dustproof plates 2b are provided with positioning grooves that cooperate with the positioning block 2a5.

[0042] It should be noted that when connecting the first dustproof plate 2a and the second dustproof plate 2b, first place the two second dustproof plates 2b on the left and right sides of the connector 1a respectively, and then push the two first dustproof plates 2a from the top and bottom of the connector 1a toward the connector 1a until the positioning block 2a5 at the first dustproof plate 2a is inserted into the positioning groove in the second dustproof plate 2b to complete the splicing of the two.

[0043] See Figure 3 , Figure 4 and Figure 6 As shown, the second dustproof plate 2b is also provided with a slot, and the back of the second dustproof plate 2b is provided with a connecting block 2b1 and a threaded positioning pin 2b2. An auxiliary door 2b3 is rotatably provided in the slot.

[0044] The auxiliary door 2b3 has a fixing block 2b4 extending outward from its end. Both the connecting block 2b1 and the fixing block 2b4 have threaded holes that cooperate with the threaded positioning pin 2b2.

[0045] It should be noted that the slot at the second dustproof plate 2b and the auxiliary door 2b3, as well as the mounting slot of the first dustproof plate 2a, provide convenience for subsequent adjustments and maintenance of the connectors, avoiding the need for maintenance personnel to completely disassemble the dustproof heat-conducting component 2 during the maintenance process.

[0046] The connecting block 2b1, threaded positioning pin 2b2, fixing block 2b4, and threaded hole are used to limit the movement of the auxiliary door 2b3.

[0047] See Figure 3-5 As shown, a support block 2a6 is provided on the outer side of the mounting frame 2a2, which is horizontally arranged with the first dustproof plate 2a. The side of the support block 2a6 near the connector 1a is in contact with the back of the first dustproof plate 2a.

[0048] It should be noted that the support block 2a6 allows operators to control the distance the mounting frame 2a2 is pushed into the mounting slot, preventing over-insertion of the mounting frame 2a2 that could cause it to contact and impact the connector. It also facilitates the connection between the threaded locating pin 2b2 and the threaded hole at the mounting frame 2a2.

[0049] See Figure 5 As shown, a protective awning 2a7 is provided on the side of the mounting frame 2a2 away from the connector, and the protective awning 2a7 is flared.

[0050] It should be noted that the horn-shaped protective eaves 2a7 can effectively protect the heat dissipation mesh 2a1 inside the mounting frame 2a2, preventing workers from accidentally touching the heat dissipation mesh 2a1 during work, which could lead to deformation and damage to the heat dissipation mesh 2a1.

[0051] See Figure 1 As shown, both ends of the two first dustproof plates 2a are provided with connecting parts extending along the direction of the connector 1a, and fastening bolts are provided at the connecting parts. The first dustproof plates 2a are fixedly connected to the busbar body 1 by the fastening bolts.

[0052] Both ends of the two second dustproof plates 2b are provided with extensions along the direction of the connector 1a. The extensions and the connecting parts are both located in the grooves on the outside of the busbar trunking body 1.

[0053] It should be noted that after the first dustproof plate 2a and the second dustproof plate 2b are spliced ​​together, the dustproof heat-conducting component 2 and the busbar trunking body 1 can be installed by using fastening bolts to fix the first dustproof plate 2a and the groove of the busbar trunking body 1 through the connecting part.

[0054] Meanwhile, the extension reduces the gap between the busbar trunking body 1 and the dustproof and heat-conducting component 2 after installation, thus improving the dustproof effect of the dustproof and heat-conducting component 2.

[0055] The above embodiments are merely illustrative of one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
