Description

Technical Field

[0001] This utility model relates to the field of dense busbar trunking technology, specifically a novel dense busbar trunking. Background Technology

[0002] High-density busbar trunking is a power distribution system consisting of highly conductive copper busbars and a metal casing. The tightly arranged copper busbars increase current carrying capacity, meeting various high-load demands. It also boasts advantages such as compact structure and small footprint. Currently, high-density busbar trunking connections typically use connectors, which usually consist of several isolation plates and two insulating plates. Bolts are used to clamp the isolation plates on the insulating plates, making the copper busbar connection operation cumbersome. Furthermore, the user must hold the connector during installation, and manual pressing of the high-density busbar trunking is required while simultaneously tightening the bolts. This cumbersome operation can easily cause the copper busbars to shift during connection, hindering installation.

[0003] Based on this, a new type of high-density busbar trunking is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a new type of dense busbar trunking to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel high-density busbar trunking includes an outer shell. A cover plate is located at each of the upper and lower ends of the outer shell. An aluminum-magnesium alloy busbar is mounted on the surface of each cover plate. The two cover plates and the two aluminum-magnesium alloy busbars form a double-T structure. A copper busbar is located in the middle of the outer shell, with a portion of the copper busbar exposed and the remainder embedded inside the outer shell. A protective plate is located on each side of the copper busbar. The outer shell is equipped with a quick-connect device for rapidly connecting to other high-density busbar trunking. The quick-connect device includes a quick-connect interface, which is slidably connected to a locking mechanism for quickly securing the outer shell.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the locking mechanism includes a connector, with several isolation plates between two connectors, and several fixing screws between the connectors and the isolation plates. The fixing screws are threadedly connected to bolts for clamping the isolation plates. The connectors have two operating grooves on their surfaces. One end of a plug is fixedly connected inside the operating groove, and the other end of the plug is slidably connected to a quick-connect interface. The plug has a fixing device inside that provides a limiting and fixing function when the plug is inserted into the quick-connect interface.

[0009] In one alternative: the fixing device includes a transmission block, the transmission block is slidably connected to the inside of the insert block, a rotating seat is fixedly connected to each side of the transmission block, the rotating seat is rotatably connected to a rotating shaft, a limiting block is fixedly connected to the surface of the rotating shaft, and a driving component for driving the transmission block to unfold is provided between the limiting block and the transmission block.

[0010] In one alternative: the drive assembly includes a first spring, one end of which is fixedly connected to the surface of the limiting block, and the other end of which is fixedly connected to the surface of the transmission block. The front end of the transmission block is fixedly connected to a disassembly element that facilitates the retraction of the limiting block.

[0011] In one alternative: the disassembly element includes a second spring, one end of the insert block is fixedly connected to the inner wall of the insert block, the other end of the second spring is fixedly connected to the surface of the transmission block, the insert block has a second sliding groove for accommodating the limiting block, pull rods are fixed on both sides of the transmission block, and the insert block has a first sliding groove for the pull rods to slide.

[0012] In one alternative: the quick-connect interface has a lubricating oil groove inside.

[0013] In one alternative: the housing is made of aluminum-magnesium alloy, and the surface of the housing is provided with heat dissipation grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model reduces the required thickness of the conductor copper busbar by setting a cover plate and an aluminum-magnesium alloy busbar to form a double-T structure, which greatly reduces production costs.

[0016] 2. This utility model inserts a plug into a quick-connect interface and uses two limiting blocks to unfold and press against the inner wall of the quick-connect interface, providing a limit for the connector before clamping the isolation plate. In traditional dense busbar connections, there is only one limiting post between the isolation block and the outer shell, which requires multiple adjustments of the limiting post to connect two dense busbars. This solves the problem that the copper plates need to be clamped during connection, and repeated adjustments of the isolation plate tightness can easily cause the copper plates to tilt during connection, creating a safety hazard.

[0017] 3. This utility model uses a push rod to drive the transmission block to move, and a second sliding groove to house the limiting block, so that the plug does not interfere with the quick-connect interface when the plug is inserted or pulled out. When the pull rod is released, the plug drives the transmission block to reset, and the transmission block drives the limiting block to unfold, which facilitates the connection between the connector and the high-density busbar trunking and improves work efficiency.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-3 As shown, a novel high-density busbar trunking includes a housing 101. A cover plate 102 is provided at each of the upper and lower ends of the housing 101. An aluminum-magnesium alloy busbar 106 is provided on the surface of each cover plate 102. The two cover plates 102 and the two aluminum-magnesium alloy busbars 106 form a double-T structure. A copper busbar 104 is provided in the middle of the housing 101. A portion of the copper busbar 104 is exposed outside the housing 101, while the remaining portion is embedded inside the housing 101. A protective plate 103 is provided on each side of the copper busbar 104. The housing 101 is equipped with a quick-connect device for quickly connecting to other high-density busbar trunkings. The quick-connect device includes... The quick-connect interface 105 is slidably connected to the locking mechanism of the quick-fixing housing 101. The housing 101 provides protection and insulation for the copper busbar 104. The cover plate 102 and the aluminum-magnesium alloy busbar 106 form a double-T structure to reduce the thickness of the copper busbar 104 and reduce production costs. The protective plate 103 provides protection for both sides of the copper busbar 104. The housing 101 is made of lead-magnesium alloy and has heat dissipation grooves on its surface. By using lead-magnesium alloy, it is lightweight and high-strength, with excellent corrosion resistance and heat dissipation performance. The heat dissipation grooves improve heat dissipation efficiency and ensure the stable operation of the system.

[0026] In one embodiment, such as Figure 2 and Figure 3As shown, the locking mechanism includes a connector 201, with several isolation plates 202 between two connectors 201. Several fixing screws 203 are provided between the connectors 201 and the isolation plates 202. The fixing screws 203 are threadedly connected to bolts for clamping the isolation plates 202. The connectors 201 have two operating grooves 204 on their surfaces. One end of a plug block 301 is fixedly connected inside the operating groove 204. The other end of the plug block 301 is slidably connected to a quick-connect interface 105. The plug block 301 has a fixing device inside that provides a limiting and fixing device when the plug block 301 is inserted into the quick-connect interface 105. By inserting copper busbars 104 into the middle of the isolation plates 202, and inserting a compact busbar trough into each of the two sides of the connectors 201, the copper busbars 104 on the compact busbar trough are connected in the middle of the isolation plates 202. By tightening the nuts on the two connectors 201, the isolation plates 202 clamp the connected copper busbars 104, thus completing the connection of the compact busbar trough.

[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the quick-connect interface 105 has a space at the contact position with the plug 301 for the plug 301 to move laterally, so as not to interfere with the clamping movement of the connector 201;

[0028] In one embodiment, such as Figure 3 and Figure 4 As shown, the fixing device includes a transmission block 302, which is slidably connected to the inside of the insertion block 301. A rotating seat 305 is fixedly connected to each side of the transmission block 302. The rotating seat 305 is rotatably connected to the rotating shaft 306. A limiting block 307 is fixedly connected to the surface of the rotating shaft 306. A driving component for driving the transmission block 302 to unfold is provided between the limiting block 307 and the transmission block 302. The insertion block 301 is inserted into the quick connector 105. The two limiting blocks 307 unfold and press against the inner wall of the quick connector 105, providing a limit for the connector 201 before clamping the isolation plate 202. This solves the problem that the isolation plates 202 are too tight and it is inconvenient for the copper busbar 104 to be connected.

[0029] In one embodiment, such as Figure 3 and Figure 4 As shown, the driving assembly includes a first spring 308. One end of the first spring 308 is fixedly connected to the surface of the limiting block 307, and the other end of the first spring 308 is fixedly connected to the surface of the transmission block 302. The front end of the transmission block 302 is fixedly connected to a disassembly element that facilitates the retraction of the limiting block 307. The first spring 308 drives the limiting block 307 to move. The limiting block 307 rotates through the mutual cooperation of the rotating seat 305 and the rotating shaft 306, and automatically unfolds the limiting block 307.

[0030] In one embodiment, such as Figure 4 and Figure 5As shown, the disassembly element includes a second spring 310. One end of the insert block 301 is fixedly connected to the inner wall of the insert block 301, and the other end of the second spring 310 is fixedly connected to the surface of the transmission block 302. The insert block 301 has a second sliding groove 309 for accommodating the limiting block 307. Pull rods 303 are fixed on both sides of the transmission block 302. The insert block 301 has a first sliding groove 304 for the pull rods 303 to slide. By pushing the pull rods 303, the pull rods... 303 drives the transmission block 302 to move, which in turn drives the rotating seat 305 and the rotating shaft 306 to move. The second slide groove 309 houses the limiting block 307, so that the insert 301 does not interfere with the quick-connect interface 105 when inserting or removing the insert 301. After the insert 301 is assembled or disassembled, the pull rod 303 is released, and the insert 301 drives the transmission block 302 to reset. The transmission block 302 drives the limiting block 307 to reset, so that the limiting block 307 automatically unfolds.

[0031] The above embodiments disclose a novel high-density busbar trunking system. The outer casing 101 provides protection and insulation for the copper busbar 104. The cover plate 102 and the aluminum-magnesium alloy busbar 106 form a double-T structure, reducing the thickness of the copper busbar 104 and lowering production costs. The protective plate 103 provides protection for both sides of the copper busbar 104. Pushing the pull rod 303 moves the transmission block 302, which in turn moves the rotating seat 305 and the rotating shaft 306. The second sliding groove 309 accommodates the limiting block 307, ensuring that the insertion block 301 does not interfere with the insertion of the insertion block 301. Pull out the quick connector 105. After assembling or disassembling the plug block 301, release the pull rod 303. The plug block 301 drives the transmission block 302 to reset, and the transmission block 302 drives the limit block 307 to reset, so that the limit block 307 automatically unfolds. By inserting the copper busbar 104 into the middle of the isolation plate 202, and inserting a compact busbar trough into each side of the connector 201, the copper busbar 104 on the compact busbar trough is connected in the middle of the isolation plate 202. Tighten the two connectors 201 with nuts so that the isolation plate 202 clamps the connected copper busbar 104, thus completing the connection of the compact busbar trough.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
