[0002] In the power system, the busbar connects the various current-carrying branch circuits in the distribution device, and plays the role of collecting, distributing and transmitting electric energy. The busbar is usually made of copper or aluminum, which has the characteristics of high current density, low resistance, and small skin effect. At present, the main connection form between the busbar and the branch copper busbar is to use bolts to knock the branch copper busbar and the busbar together, or to crimp the copper busbar to the side wall of the busbar.

[0031] In the power system, the busbar connects the various current-carrying branch circuits in the distribution device, and plays the role of collecting, distributing and transmitting electric energy. The busbar is usually made of copper or aluminum, which has the characteristics of high current density, low resistance, and small skin effect. At present, the main connection form between the busbar and the branch copper busbar is to use bolts to knock the branch copper busbar and the busbar together, or to crimp the copper busbar to the side wall of the busbar. When the branch copper busbar and the busbar are fastened together with bolts, it is difficult to ensure the alignment of the holes on the busbar because the busbar is large in size and multiple holes are set at intervals, and high precision is required; while the method of crimping the copper busbar to the side wall of the busbar has low requirements for busbar installation accuracy, but during installation, the accessories are not fixed and are easy to fall off the busbar, which is inconvenient to install.

[0032] In view of this, the utility model provides a busbar connection structure. Figures 1 to 5 The busbar connection structure provided by the present invention is an embodiment, and the busbar connection structure will be described below in conjunction with specific drawings.

[0033] See also Figures 1 to 5 The busbar connection structure includes a connecting plate 1, a fixing plate 2, a fastening assembly 3 and an anti-falling connector 5. The connecting plate 1 and the fixing plate 2 are spaced apart along a first direction to be clamped at both ends of the busbar 200. One end of the fastening assembly 3 is connected to the fixing plate 2, and the other end of the fastening assembly 3 is used for detachable connection with the bus branch 300. The connecting plate 1 is used to be arranged between the bus branch 300 and the busbar 200; the two ends of the anti-falling connector 5 are respectively connected to the connecting plate 1 and the fixing plate 2 in a limiting manner.

[0034] In the technical solution of the utility model, the connection plate 1 and the fixing plate 2 are respectively arranged at the two ends of the busbar 200, one end of the fastening assembly 3 is connected to the fixing plate 2, and the other end of the fastening assembly 3 is used to be detachably connected to the busbar branch 300. Specifically, the fastening assembly 3 and the connection plate 1 are used to clamp and fix the busbar branch 300, and the connection plate 1 and the fixing plate 2 are used to clamp and fix to the busbar 200. When the fastening assembly 3 is locked, the fastening assembly 3 pushes the busbar branch 300 until it is tightly fitted to the connection plate 1 to be electrically connected to the connection plate 1. At the same time, the connection plate 1 and the fixing plate 2 are fastened to the busbar 200, so that the connection plate 1 and the busbar 200 are tightly fitted, and then the busbar branch 300 is firmly connected to the busbar 200 through the connection plate 1. On this basis, the connecting plate 1 and the fixed plate 2 are connected by an anti-fall connector 5. Specifically, the two ends of the anti-fall connector 5 are respectively connected to the connecting plate 1 and the fixed plate 2 in a limited position. When the fastening assembly 3 is not fastened, the anti-fall connector 5 connects the connecting plate 1 and the fixed plate 2 to prevent them from falling off the busbar 200. At this time, the connecting plate 1 and the fixed plate 2 can move on the busbar 200 to adjust the connection point. In summary, the bus branch 300 is connected to the bus bus 200 by crimping the bus branch 300 to the connecting plate 1, so that the structure of the bus branch 300 is not limited to a plate structure, but can also be a cable structure, which is more applicable; at the same time, the anti-fall connector 5 movably installs the connecting plate 1 and the fixed plate 2 on the bus bus 200, so that when the bus is adjusted, the connecting plate 1, the fixed plate 2 and the fastening assembly 3 arranged on the connecting plate 1 and the fixed plate 2 can be freely moved along the bus bus, which is convenient for operation, and the fixed plate 2 and the connecting plate 1 will not fall off, so the safety is high.

[0035] It can be understood that the specific structure of the anti-fall connector 5 is not limited, and the fixing plate 2 can be hung on the connecting plate 1 to prevent it from falling off. For example, an anti-fall rope structure can be used to connect the connecting plate 1 and the fixing plate 2 through the anti-fall rope to connect the fixing plate 2 to the connecting plate 1. However, considering that when operating in a small space, the flexible structure similar to the anti-fall rope is not easy to control and difficult to perform fine operations, which leads to inconvenient operation. Therefore, in this embodiment, the anti-fall connector 5 is configured as a rigid connecting rod assembly 51, and the connecting rod assembly 51 includes a rod 511 and a limit member 512. The limit member 512 is connected to the rod 511 and is arranged at one end of the rod 511 close to the fixing plate 2. The limit member 512 is provided with a limit protrusion 512a, and the limit protrusion 512a extends along the second direction and is connected to the fixing plate 2 in a limit position. Specifically, the connecting rod assembly 51 includes a rod 511 and a limit member 512. The limit member 512 is provided with a limit protrusion 512a. The rod 511 is a rigid structure, which has the beneficial effect of easy control operation. At the same time, the connecting plate 1 and the fixed plate 2 are connected by the rod 511, and the fixed plate 2 is not easy to move laterally, so as to keep the corresponding connection plate 1 and the fixed plate 2 in the first direction as much as possible, and also show good controllability. When the connecting plate 1 and the fixed plate 2 move on the busbar 200, the connecting plate 1 and the fixed plate 2 can maintain a good position relationship, without the need for complicated position adjustment, and easy operation.

[0036] Furthermore, the cross-sectional shape of the rod 511 is set to a polygon, and a corresponding polygonal through hole is provided on the fixing plate 2. The cross-sectional shape of the rod 511 does not affect its anti-falling connection function for the connecting plate 1 and the fixing plate 2, so it can be set without limitation. The cross-sectional shape is set to a circle, which also has the main hanging anti-falling function. However, when the rod 511 is a cylindrical structure, the fixing plate 2 and the connecting plate 1 can rotate relative to each other around the axis of the rod 511, resulting in an offset in the alignment relationship between the two, affecting the fastening operation of the connecting plate 1 and the fixing plate 2. Therefore, in this embodiment, the cross-sectional shape of the rod 511 is set to a polygon, and a corresponding polygonal through hole is provided on the fixing plate 2, so that when the rod 511 is inserted into the polygonal through hole, the rod 511 and the fixing plate 2 will not rotate relative to each other, and the upper end of the rod 511 is connected to the connecting plate 1, so that the connecting plate 1 and the fixing plate 2 will not rotate relative to each other, so that the alignment relationship between the connecting plate 1 and the fixing plate 2 can be further guaranteed, which is convenient for installation and fixing operations.

[0037] Specifically, the rod 511 is disposed through the fixing plate 2 , and the limiting protrusion 512 a is located on a side of the fixing plate 2 away from the connecting plate 1 . The limiting protrusion 512a is mainly used for limiting connection with the fixing plate 2, that is, when the fastening assembly 3 is unlocked, the limiting protrusion 512a can act on the fixing plate 2 to prevent the fixing plate 2 from falling off, and the fixing plate 2 and the connecting plate 1 are loosened and can move on the bus bus 200. When the fastening assembly 3 is locked, the fixing plate 2 and the connecting plate 1 are driven to clamp the bus bus 200. At this time, the limiting protrusion 512a does not limit the movement of the fixing plate 2 toward the connecting plate 1, so the connection position of the limiting protrusion 512a and the fixing plate 2 can be not limited. In this embodiment, one end of the rod 511 is connected to the connecting plate 1, and the other end is penetrated through the fixing plate 2, and the limiting protrusion 512a is set at the position where the fixing plate 2 is away from the connecting plate 1. In this way, the fixing plate 2 can move along the anti-fall connecting piece 5 close to or away from the connecting plate 1, but is limited by the limiting protrusion 512a to meet the structural requirements.

[0038] Specifically, the limiting member 512 includes a first screw member 513, which is threadedly connected to the end of the rod 511, and the end of the first screw member 513 away from the rod 511 forms a limiting protrusion 512a. The setting form of the limiting protrusion 512a also does not need to be limited, and it can be fixed to the end of the rod 511 to support and limit the fixing plate 2 to prevent it from falling. Specifically, it can be a structure integrally formed on the rod 511, a structure fixedly connected to the rod 511 by welding and bonding, and a structure detachably arranged on the rod 511. In this embodiment, the limiting protrusion 512a is set as a structure detachably arranged on the rod 511, which has more flexibility on the basis of connection stability, and is convenient for the installation and removal of the connecting plate 1 and the fixing plate 2 on the busbar 200. The structure that can be detachably arranged on the rod 511 can also be arranged in various ways, including but not limited to a limit pin that can be inserted into the rod 511 and a threaded connector that is threadedly connected to the rod 511. In the present embodiment, a first screw connector 513 that is threadedly connected to the rod 511 is specifically adopted. Compared with the above-mentioned pin structure, the threaded connection structure is obviously more stable and not easy to fall off, so as to ensure the stability of the anti-fall connector 5. Furthermore, the first screw connector 513 can be a structure that is screwed to the external thread on the rod 511, or it can be a structure that is screwed to the internal thread in the inner cavity opened at the end of the rod 511, both of which can ensure the stability of the connection. However, it is obvious that opening an inner cavity on the rod 511 and providing an internal thread so that the first screw connector 513 extends into the above-mentioned inner cavity and is threadedly connected to the rod 511 plays a certain protective role for the internal thread and the first screw connector 513, thereby extending their service life. Therefore, in this embodiment, an inner cavity is opened at the end of the rod 511, and an internal thread structure is provided in the inner cavity, which is threadedly connected to the first screw connector 513.

[0039] In addition, the connecting rod assembly 51 further includes a second screw connection member 514 , and one end of the rod member 511 close to the connecting plate 1 is threadedly connected to the connecting plate 1 through the second screw connection member 514 . The connection method between the rod 511 and the connecting plate 1 also does not need to be limited, and it only needs to be able to ensure that it is firmly fixed to the connecting plate 1. Similar to the setting of the limiting protrusion 512a on the rod 511, the way in which the rod 511 is set on the connecting plate 1 can be to form the rod 511 and the connecting plate 1 as one piece, to fix the rod 511 and the connecting plate 1 by welding and bonding, and to fix the rod 511 and the connecting plate 1 by a detachable connection structure. In this embodiment, a detachable connection method is also adopted. On the one hand, the rod 511 is almost perpendicular to the connecting plate 1, and it is not convenient to carry and transport after being integrally formed. On the other hand, a detachable connection method is adopted, and specifically a detachable connection method similar to the connection of the first screw member 513 to the rod 511. The two ends of the rod 511 can be set to the same structure. During on-site installation, there is no need to distinguish between the two ends of the rod 511, which makes the rod 511 more universal, simplifies the operation process, and facilitates operation. Specifically, an inner cavity is opened at each end of the rod 511, and an internal thread is set on the inner wall of the inner cavity. When the rod 511 is fixed to the connecting plate 1, the inner cavity on the rod 511 is aligned with the fixing hole reserved on the connecting plate 1, and the second screw connection 514 is passed through the fixing hole on the connecting plate 1 to connect with the rod 511, so as to fix the rod 511 to the connecting plate 1.

[0040] In addition, the fastening assembly 3 includes a bolt assembly, which includes a bolt 31 and a nut 32. The bolt 31 penetrates the fixed plate 2 and the connecting plate 1 along a first direction, and the nut 32 can be adjustably connected to the bus branch 300 along the first direction to adjust the tightness between the bus branch 300 and the connecting plate 1; a support member 4 is also fixed to the side of the fixed plate 2 away from the connecting plate 1, and the support member 4 has a support portion 41 covering the bolt assembly. The actual function of the fastening component 3 is to clamp the bus branch 300, the connecting plate 1, the bus busbar 200 and the fixed plate 2, that is, the fastening component 3 can actually be set as a clamping component, and the two clamping ends of the clamping component are respectively arranged below the fixed plate 2 and above the connecting plate 1, so as to achieve the required fastening function by clamping. However, it is obvious that the clamping and fixing method of the clamping component is complex in structure and has poor stability, and it is easy to fall off, resulting in disconnection between the bus branch 300 and the bus busbar 200, affecting the stability of the busbar connection structure 100. Therefore, this embodiment mainly adopts other fixing methods, specifically the bolt 31 nut 32 connection method, that is, the fastening component 3 includes a bolt assembly, and the bolt 31 in the bolt assembly is penetrated through the fixed plate 2 and the connecting plate 1. On the one hand, the bolt 31 nut 32 is used to connect to fasten the connecting plate 1, the bus busbar 200 and the fixed plate 2. On the other hand, the bolt 31 also plays the function of relative positioning of the connecting plate 1 and the fixed plate 2. In addition, the bolts 31 are arranged to pass through the fixing plate 2 and the connecting plate 1 from bottom to top, and the bus branch 300 is fixed above the connecting plate 1 and connected to the fixing plate 2 by operating the nuts 32. On the one hand, it is easier to operate the smaller nuts 32 than the larger bolts 31. On the other hand, the smaller nuts 32 are easy to slip out of the hand. When the nuts 32 are arranged below the fixing plate 2 and screwed onto the bolts 31, they are easy to fall off by mistake, causing electrical hazards. Based on this, the same problem as the fixing plate 2 is also considered. When the nut 32 is removed from the bolt 31 to adjust the confluence branch 300, the bolt 31 will lose the support of the connecting plate 1 connected by the nut 32. The screw head of the bolt 31 needs to be abutted against the lower end surface of the fixing plate 2 for clamping and fixing. When the support is lost, the bolt 31 will fall from the bottom of the fixing plate 2. Although it can be manually protected to prevent it from falling, on the one hand, it is inconvenient to operate in a narrow space, and on the other hand, it is unstable to control it manually, which is not practical. Therefore, in this embodiment, a support member 4 is also provided under the fixing plate 2, and the support member 4 has a support portion 41 extending to the bottom of the bolt 31, so that when the nut 32 and the bolt 31 are released from the fixed connection, the fixing plate 2 is supported by the anti-falling connecting member 5, and the support member 4 under the fixing plate 2 supports the bolt 31 through the support portion 41 to prevent the bolt 31 from falling, and at this time, the top of the bolt 31 still protrudes above the connecting plate 1, so that the nut 32 can be used to reconnect with the bolt 31 for tightening.

[0041] Specifically, the support member 4 includes a support plate 4a fixed to the fixed plate 2, the middle part of the support plate 4a is bent away from the fixed plate to form a groove 41a, and the bottom of the groove 41a forms a support portion 41. The structure of the support member 4 can also be set in various ways, for example, it is set as a screw-connected member threadedly connected to the bottom of the fixed plate 2, and the screw head protruding laterally from the screw-connected member is used as the support portion 41 to support the bolt 31; it is also set as a protective net fixed to the fixed plate 2, and the protective net supports the limiting bolt 31, which can realize the limiting support of the bolt 31 to play the role of anti-falling. In this embodiment, a support plate 4a is fixed below the fixed plate 2, and a groove 41a is formed by bending the support plate 4a. The groove 41a is covered on the bolt 31 so that the bottom of the groove 41a forms the support portion 41. The structure is simple and stable, and it is convenient for it to be fixed to the fixed plate 2. Specifically, the support plate 4a is fixed to the fixed plate 2 by screws. In addition, it should be noted that an avoidance gap needs to be provided at the position of the support plate 4 a corresponding to the anti-falling connection piece 5 so as to avoid the anti-falling connection piece 5 .

[0042] Furthermore, the groove wall of the groove 41a abuts against the head of the bolt 31 to limit its rotation. When the nut 32 is threadedly connected to the bolt 31, it may drive the bolt 31 to rotate. In this case, it is not convenient to manually position the bolt 31. Therefore, in this application, the groove wall interval of the groove 41a is directly set so that when the head of the bolt 31 is placed in the groove 41a, the groove wall of the groove 41a limits the rotation of the bolt 31. In this way, the user does not need to manually position the bolt 31. When the nut 32 is threadedly connected to the bolt 31, the bolt 31 no longer rotates, which is convenient for operation.

[0043] The utility model also provides a busbar 1000, which includes a busbar 200, a busbar branch 300, and a busbar connection structure 100, and the busbar connection structure 100 is used to fix the busbar 200 and the busbar branch 300. The specific structure of the busbar connection structure 100 refers to the above embodiment. Since the busbar 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0044] Specifically, the bus branch 300 includes a branch connection plate 1 or a branch cable. Based on the above bus connection structure 100, the connection plate 1 and the connection cable can be connected, so the bus branch 300 on the bus can be a branch connection plate 1 or a branch cable, which is mainly based on the structure of the bus and is not limited here.

[0045] The utility model also provides an electric power system, which includes a busbar 1000. The specific structure of the busbar 1000 is referred to the above embodiment.
