Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, in particular to a cable branch box which is convenient for replacing copper busbars and a copper busbar replacement method thereof. Background Art

[0002] In power distribution systems, cable branch boxes serve as crucial distribution nodes, primarily distributing power from upstream sources to multiple downstream load circuits, electrically connecting input and output conductors. Copper busbars, the core conductive component for current transmission and distribution within the branch box, directly impact the operational stability of the distribution system. Traditional copper busbars in cable branch boxes are typically fixed to the conductive sockets within the branch box using bolts, welding, or direct embedding. When copper busbars become oxidized, experience poor contact, or become damaged due to long-term operation and require replacement, the fixing bolts must be removed and the connection to the output conductors disconnected. This process is cumbersome and time-consuming. Some copper busbars with embedded connections require prying with specialized tools, which can cause mechanical damage to the conductive sockets or the busbar itself, compromising contact reliability after reinstallation. Furthermore, busbar replacement requires a power outage, reducing power continuity, increasing user inconvenience, and incurring financial losses. This loss is particularly severe for equipment that requires continuous operation.

[0003] A Chinese patent application numbered CN202111610119.7 discloses a cable branching box. The cable branching tool comprises a branching box, wherein a plurality of first accommodating cavities are provided in the branching box, wherein the plurality of first accommodating cavities are not interconnected, and the first accommodating cavities are used to accommodate the branch lines of the cable, and the plurality of first accommodating cavities correspond one-to-one to the plurality of branch lines, and the first accommodating cavities are provided with a first opening connected to the outside world, and the first opening is used for inserting the branch line into the first accommodating cavity, and a plurality of conductive parts are provided on the outer peripheral surface of the branching box, and the branch line inserted into the first accommodating cavity can be electrically connected to the conductive parts, and the plurality of conductive parts correspond one-to-one to the plurality of first accommodating cavities. After the cable of the cable branching box is branched through the cable branching tool, the branch connection of the cable can be realized by only connecting the conductive parts to other devices respectively, which greatly improves the efficiency of the cable branch connection.

[0004] The copper busbars in existing cable branch boxes are prone to vibration, thermal expansion and contraction during long-term operation, which can easily lead to a decrease in contact pressure and an increase in contact resistance, thereby threatening the safety of the power distribution system. At the same time, the existing cable branch boxes have the problem of difficulty in replacing the copper busbars, and the copper busbar replacement process is difficult to avoid the impact of power outages. Therefore, there is an urgent need for a cable branch box with reliable connection, convenient and safe copper busbar replacement, and the ability to avoid power outages during copper busbar replacement. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a cable branch box and a copper busbar replacement method thereof that is convenient for replacing copper busbars. The cable branch box can realize a one-to-many connection between input conductors and input conductors through a copper busbar plug-in mechanism. The copper busbar plug-in mechanism has a firm and reliable conductive connection and can quickly realize the installation and detachment of the main copper busbar. The main copper busbar of the cable branch box and the input conductor are disconnected from the input conductor at the same time, which makes the main copper busbar easy to separate, ensures that the main copper busbar is easy to replace, and avoids the generation of electric arcs. The card plug-in mechanism of the cable branch box can quickly realize the live disconnection of the main copper busbar by sliding up first and then sliding down, and combined with the sliding conductive connection of the auxiliary copper busbar, it can realize both the rapid de-energization replacement of the main copper busbar and the continuous power supply during the replacement process of the main copper busbar.

[0029] The beneficial effects of the cable branch box and copper busbar replacement method of the present invention that are convenient for replacing copper busbars are as follows:

[0030] (1) The cable branch box connects the output conductors to the input conductors one by one through multiple copper busbar plug-in mechanisms. The plug-in mechanism includes a fixed plug-in seat and a plug-in seat plate. Two elastic buckle plates are provided in the fixed plug-in seat, and a plug-in gap is formed between the two elastic buckle plates. A main copper busbar is fixed on the plug-in seat plate. A guide wedge is provided on the top of the main copper busbar, and a sliding wedge is also provided on the outside of the main copper busbar. When the main copper busbar is connected, the main copper busbar can slide upward directly, and the guide wedge pushes the elastic buckle plate to open, so that the guide wedge is inserted above the elastic buckle plate. In this way, the elastic buckle plate can elastically clamp the main copper busbar, and the top and bottom of the guide wedge are in contact with the top of the elastic buckle plate. This can avoid the problem of increased contact resistance caused by vibration or thermal expansion and contraction in traditional plane contact, and at the same time prevent the copper busbar from falling off, so as to achieve reliable electrical connection between the main copper busbar and the plug-in seat plate. When the main copper busbar needs to be replaced, it can be detached by first sliding it upward and then downward. During the upward sliding process, the sliding wedge slides above the elastic gusset plate. Then, during the downward sliding process, the inclined surface of the sliding wedge drives the elastic gusset plate to open, thereby completely detaching the main copper busbar from the socket plate. This cable branch box can easily separate the main copper busbar while ensuring a firm and reliable main electrical connection, ensuring that the main copper busbar is easy to replace.

[0031] (2) The main copper busbar of the cable branch box is slidably set on the plug-in base plate through a copper busbar slider. The copper busbar slider is elastically pressed on the output conductor through an elastic member. A separation wedge is also provided under the plug-in base plate. The separation wedge can drive the copper busbar slider to move right during the sliding separation process of the main copper busbar, so that the main copper busbar can be quickly and simultaneously separated from the input conductor and the output conductor. This can avoid the arc generated when the main copper busbar is de-energized and ensure that the main copper busbar is not energized during the replacement process, thereby improving the efficiency and safety of the main copper busbar replacement.

[0032] (3) The output conductor of the cable branch box is fixed on the copper busbar slider. A secondary copper busbar is also fixed on the output conductor. The secondary copper busbar extends upward to the conductive slot in the conductive slot. The secondary copper busbar is slidably connected to the conductive slot. When the main copper busbar sliding plug-in base plate is replaced, the secondary copper busbar can maintain the electrical connection with the input conductor and the output conductor, thereby ensuring that there is no need to shut down the power during the replacement of the main copper busbar and ensuring the continuity of power supply during the replacement of the main copper busbar. In addition, after the replacement of the main copper busbar is completed, the secondary copper busbar can be separated from the conductive plug-in by rotating the conductive plug-in. This can shorten the conduction time of the secondary copper busbar and extend the service life of the secondary copper busbar, so that the secondary copper busbar can support multiple replacements of the main copper busbar.

Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0044] Although the steps in the present invention are arranged with numbers, they are not intended to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0045] Please refer to Figures 1 to 8 The present invention provides a cable branch box that facilitates copper busbar replacement. The branch box 100 comprises a rectangular box body (the cover is not shown). The branch box 100 houses an input conductor 102 and multiple output conductors 700, as well as multiple copper busbar plug-in mechanisms. The input conductor 102 is secured within the branch box 100 via insulating support bars 101.

[0046] Each brand plug-in mechanism includes an upper conductive connection seat, a sliding plug-in component and a sliding drive component.

[0047] The upper conductive connection seat includes a conductive plate 200 and a fixed socket fixed on the conductive plate 200 . The conductive plate 200 is fixed in the branch box 100 through an insulating support pad 201 . The conductive plate 200 is electrically connected to the input conductor 102 through a connecting guide rod 603 .

[0048] The fixed socket includes an N-shaped fixed frame 300 and two elastic buckle plates 301. The fixed frame 300 is fixed on the conductive plate 200. The elastic buckle plates 301 and the fixed frame 300 are an integrated structure. A plug-in gap is formed between the two elastic buckle plates 301. The inner side surfaces of the two elastic buckle plates 301 are arc-shaped surfaces, and the plug-in gap gradually becomes smaller in the upward direction.

[0049] The sliding plug assembly includes two fixed slide rails 601 and a plug base plate 600; the plug base plate 600 includes two fixed mounting blocks 600 and two connecting guide rods 603. The fixed slide rails 601 are fixedly installed in the branch box 100. The two fixed mounting blocks 600 are respectively fixed to the slide rail blocks 602. The slide rail blocks 602 slide and engage with the fixed slide rails 601. In this way, the two ends of the plug base plate 600 can be slidably arranged on the two fixed slide rails 601 to ensure that it can slide along the two fixed slide rails 601. The sliding drive assembly is connected to the plug base plate 600 and is used to drive the plug base plate 600 to slide.

[0050] The output conductor 700 is fixed on the plug-in base plate 600. The plug-in base plate 600 is also provided with a copper busbar slider 401. The copper busbar slider 401 is detachably provided with a main copper busbar 400. In this embodiment, the main copper busbar 400 is fixed to the copper busbar slider 401 by screws.

[0051] The main copper busbar 400 is provided with a guide wedge 410 and a sliding wedge 420. The guide wedge 410 is fixed to the top of the main copper busbar 400. The sliding wedge 420 has a sliding socket hole 421 in the middle. The sliding wedge 420 slides onto the main copper busbar 400 through the sliding socket hole 421. The copper busbar slider 401 is provided with an elastic member 604. The elastic member 604 is a compressed coil spring. The elastic member 604 elastically compresses the copper busbar slider 401, electrically connecting the main copper busbar 400 to the output conductor 700. The guide wedge 410 is provided with a guide wedge surface on both sides. The horizontal distance between the two guide wedge surfaces gradually decreases in the upward direction. The sliding wedge 420 is provided with a sliding wedge surface on both sides. The horizontal distance between the two sliding wedge surfaces gradually increases in the upward direction. The top width of the sliding wedge surface is greater than the bottom width of the guide wedge 410.

[0052] After the main copper busbar 400 is installed, the two elastic clips 301 clamp the copper busbar slider 401 through elastic force to achieve reliable electrical connection, avoiding the problem of increased contact resistance caused by vibration or thermal expansion and contraction in traditional planar contacts.

[0053] A separation wedge 800 is fixedly provided in the branch box 100 . The separation wedge 800 is a triangular block and is used to separate the output conductor 700 and the copper busbar slider 401 when the socket plate 600 slides downward.

[0054] The cable branch box conductively connects the output conductor 700 with the input conductor 102 one by one through multiple copper busbar plug-in mechanisms. The plug-in mechanism includes a fixed plug-in seat and a plug-in seat plate 600, wherein two elastic buckle plates 301 are provided in the fixed plug-in seat, and a plug-in gap is formed between the two elastic buckle plates 301; when the main copper busbar 400 is connected, the main copper busbar 400 can slide upward directly, and the guide wedge block 410 pushes the elastic buckle plate 301 to open, so that the guide wedge block 410 is inserted above the elastic buckle plate 301, so that the elastic buckle plate 301 can elastically clamp the main copper busbar 400, and the top and bottom of the guide wedge block 410 are in contact with the top of the elastic buckle plate 301, which can avoid the problem of increased contact resistance caused by vibration or thermal expansion and contraction of traditional plane contact, and at the same time prevent the copper busbar from falling off, thereby realizing reliable electrical connection between the main copper busbar 400 and the plug-in seat plate 600. When the main copper busbar 400 needs to be replaced, it can be detached by first sliding it upward and then downward. During the upward sliding process, the sliding wedge 420 can slide up to above the elastic pinch plate 301. Then, during the downward sliding process, the inclined surface of the sliding wedge 420 can drive the elastic pinch plate 301 to open, thereby completely detaching the main copper busbar 400 from the socket plate 600. This cable branch box can facilitate the separation of the main copper busbar 400 while ensuring a firm and reliable main electrical connection, ensuring that the main copper busbar 400 is easy to replace.

[0055] In addition, the main copper busbar 400 of the cable branch box is slidably set on the plug-in base plate 600 through the copper busbar slider 401. The copper busbar slider 401 is elastically pressed on the output conductor 700 through the elastic member 604. A separation wedge 800 is also provided under the plug-in base plate 600. The separation wedge 800 can drive the copper busbar slider 401 to move right during the sliding separation process of the main copper busbar 400, so that the main copper busbar 400 can quickly and simultaneously complete the separation from the input conductor 102 and the output conductor 700. This can avoid the generation of arcs when the main copper busbar 400 is de-energized and can ensure that the main copper busbar 400 is not energized during the replacement process, thereby improving the efficiency and safety of replacing the main copper busbar 400.

[0056] In a preferred embodiment, a secondary copper busbar 702 is fixedly provided on the output conductor 700. The secondary copper busbar 702 is fixedly provided on the output conductor 700. A conductive slot component 210 is rotatably provided on the conductive plate 200. The conductive slot component 210 includes two slot plates, and a conductive slot 213 is provided between the two slot plates. The secondary copper busbar 702 is clamped in the conductive slot 213 and can slide in the conductive slot 213. The inner side surfaces of the two slot plates are close to the outer wall of the secondary copper busbar 702. This ensures that the secondary copper busbar 702 can still be conductively connected to the conductive slot component 210 when it slides up and down.

[0057] The secondary copper busbar 702 can be pre-installed on the output conductor 700, or it can be installed using a drive mechanism before the primary copper busbar 400 needs to be replaced. The secondary copper busbar 702 may have a lower current-carrying capacity than the primary copper busbar 400, but it can temporarily replace the primary copper busbar 400 to electrically connect the input conductor 102 and the output conductor 700. The secondary copper busbar 702 can be secured to the output conductor 700 using screws.

[0058] The conductive slot member 210 further includes a rotatable connecting plate 211, to which the ends of the two slot plates are fixedly connected. A rotatable mounting post 212 is fixedly provided on the conductive plate 200, and the rotatable connecting plate 211 is rotatably mounted on the rotatable mounting post 212. It should be noted that the chamfered side of the auxiliary copper busbar 702 provides an inclined surface, ensuring that the auxiliary copper busbar 702 can be inserted into the conductive slot 213 when the conductive slot member 210 rotates.

[0059] The output conductor 700 of the cable branch box is fixed on the copper busbar slider 401, and a secondary copper busbar 702 is also fixed on the output conductor 700. The secondary copper busbar 702 extends upward to the conductive slot 213 in the conductive slot part 210, and the secondary copper busbar 702 is slidably connected to the conductive slot 213. When the main copper busbar 400 is slidably plugged into the seat plate 600 due to replacement, the secondary copper busbar 702 can maintain the electrical connection between the input conductor 102 and the output conductor 700, thereby ensuring that there is no need to shut down the power during the replacement of the main copper busbar 400, and ensuring continuous power supply during the replacement of the main copper busbar 400. In addition, when the main copper busbar 400 is replaced, the secondary copper busbar 702 can be separated from the conductive slot part 210 by rotating the conductive slot part 210. This can shorten the conduction time of the secondary copper busbar 702, extend the service life of the secondary copper busbar 702, and enable the secondary copper busbar 702 to support multiple replacements of the main copper busbar 400.

[0060] In a preferred embodiment, sliding connection blocks 411 are fixedly provided at both ends of the copper busbar slider 401. Each sliding connection block 411 is provided with two sliding through holes, through which the two connecting guide rods 603 respectively pass. This ensures that the copper busbar slider 401 can slide along the connecting guide rods 603. Fixed connection blocks 701 are fixedly provided at both ends of the output conductor 700. The output conductor 700 is fixed to the two connecting guide rods 603 via the fixed connection blocks 701. Conductive posts are fixedly provided on the output conductor 700, and the conductive posts are used to connect the output wires. Both the sliding connection blocks 411 and the fixed connection blocks 701 are insulators.

[0061] In a preferred embodiment, the driving assembly includes a sliding limit seat 500, which is provided with a sliding limit hole 501. The end of the plug-in seat plate 600 is fixed with a sliding drive rod 502, and the sliding drive rod 502 passes through the sliding limit hole 501. The end of the sliding drive rod 502 is also provided with an insulating handle cover 503. By pushing the sliding drive rod 502 up and down, the plug-in seat plate 600 can be driven to slide along the fixed slide rail 601.

[0062] In a preferred embodiment, reference Figure 7 The top of the sliding wedge 420 is also provided with a receiving groove 422, and the receiving groove 422 is used to allow the bottom of the guide wedge 410 to be embedded in the receiving groove 422. This ensures that when the main copper busbar 400 is lowered, the top of the elastic buckle plate 301 will not press against the bottom of the guide wedge 410, ensuring that the main copper busbar 400 can smoothly detach from the fixed frame 300.

[0063] refer to Figure 9 , The present invention relates to a cable branch box copper bus replacement method, for facilitating the replacement of the copper bus of the cable branch box, the method comprising the steps of:

[0064] S1: Slide the socket plate 600 upwards to move the sliding wedge 420 on the main copper busbar 400 above the elastic buckle plate 301;

[0065] S2: Slide the connector plate 600 downward. The two sliding wedge surfaces of the sliding wedge block 420 push the two elastic buckle plates 301 apart, causing the main copper busbar 400 to move downward as a whole and detach from the connector. The wedge-shaped surface of the separation wedge block 800 pushes the copper busbar slider 401 to move horizontally, causing the copper busbar slider 401 to detach from the output conductor 700.

[0066] In this process, the main copper busbar 400 is separated from the elastic buckle plate 301 and the copper busbar slider 401 is separated from the output conductor 700 at the same time, which can instantly cut off the power supply to the main copper busbar 400 and reduce the generation of arcs.

[0067] S3: Replace the main copper busbar 400 on the copper busbar slider 401;

[0068] S4: Slide the plug-in base plate 600 upwards to move the top block of the new main copper busbar 400 to above the two elastic buckle plates 301. The two elastic buckle plates 301 press the new main copper busbar 400 from both sides.

[0069] Through the above process and the rapid completion of the de-energizing process of the main copper bar 400, the replacement efficiency of the main copper bar 400 is improved, and the replacement of the main copper bar 400 is ensured to be a de-energizing operation, thereby improving the safety of the replacement of the main copper bar 400.

[0070] Furthermore, the method further includes S0 before step S1; and S5 after step S4:

[0071] S0: Rotate the conductive slot member 210 to slide the auxiliary copper bus 702 into the conductive slot 213;

[0072] S5: Rotate the conductive slot member 210 in the reverse direction to disengage the auxiliary copper busbar 702 from the conductive slot 213, and place a protective layer on the outer surface of the auxiliary copper busbar 702 or remove the auxiliary copper busbar 702.

[0073] In step S0 of the above process, the auxiliary copper bar 702 can be used to temporarily electrically connect the input conductor 102 and the output conductor 700, ensuring continuous power supply during the replacement of the main copper bar 400. In step S5, after the main copper bar 400 is replaced, the connection between the auxiliary copper bar 702 and the input conductor 102 can be severed, eliminating the need for electrical connection. A protective layer is placed over the auxiliary copper bar 702 to further prevent oxidation, extend the service life of the auxiliary copper bar 702, and enable the auxiliary copper bar 702 to support multiple replacements of the main copper bar 400.
