[0034] See also Figures 1 to 3 To achieve the above-mentioned purpose, the utility model provides a combined busbar clamp, including at least two clamping blocks 100 , at least two connecting blocks 200 and a connecting piece 300 .

[0035] All the clamping blocks 100 are provided with a first groove 110 and a second groove 120 spaced apart from each other, and the second groove 120 is used for mounting the conductor 400 .

[0036] All the connection blocks 200 are provided with a first protrusion 210 that can be snap-fitted with the first groove 110 .

[0037] The connecting member 300 is detachably connected to two connecting blocks 200 arranged opposite to each other along the first direction, so that the two clamping blocks 100 arranged opposite to each other along the first direction clamp the conductor 400 through the clamping of the connecting blocks 200 .

[0038] In this embodiment, the snap-fitting cooperation between the first groove 110 and the first protrusion 210 can limit the relative movement of the clamping block 100 and the connecting block 200. The distance between the upper and lower connecting blocks 200 can be limited through the connecting piece 300, thereby limiting the distance between the two clamping blocks 100 that are respectively snap-fitted with the two upper and lower connecting blocks 200 and are arranged opposite to each other, thereby limiting the distance between the two second grooves 120 for installing the conductor 400.

[0039] The clamping block 100 is provided with a first groove 110 and a second groove 120 spaced apart from each other. The conductor 400 is installed in the second groove 120 of the two clamping blocks 100 projecting upward and downward. The first groove 110 is engaged with the first protrusion 210 on the connecting block 200 to limit the movement of the two clamping blocks 100 relative to the conductor 400. The connecting piece 300 is detachably connected to the two connecting blocks 200 arranged opposite to each other along the first direction to limit the two connecting blocks 200 from being separated from the corresponding clamping blocks 100, so that the clamping block 100 clamps the conductor 400. The combined busbar clamp is split into the clamping block 100 and the connecting block 200, which can be flexibly matched and combined according to different bus phase numbers, and only needs to increase or decrease the number of corresponding clamping blocks 100 and connecting blocks 200 to meet the needs of different occasions, which can avoid the impact of the busbar clamp not being able to be flexibly used in some usage scenarios, thereby making the busbar clamp more versatile, more expansible, and better able to adapt to the needs of different environments.

[0040] Preferably, the first grooves 110 are disposed on both sides of the clamping block 100, and the first protrusions 210 are located on both sides of the connecting block 200 to connect the clamping blocks 100 adjacently disposed along the second direction, and the first direction is perpendicular to the second direction.

[0041] It can be understood that first grooves 110 are provided on both sides of the clamping block 100, and first protrusions 210 are also provided on both sides of the connecting block 200. Through the connecting blocks 200 in the middle of the staggered clamping blocks 100, the clamping blocks 100 adjacent to each other in the second direction can be connected in sequence. The arrangement of the first grooves 110 and the first protrusions 210 can realize the second grooves 120 being arranged in sequence along the second direction, which can adapt to the installation of multiple conductors 400 and is more flexible.

[0042] Preferably, the first groove 110 includes a first end with a larger opening and a second end with a smaller opening, and the first end is located at the end of the clamping block 100 away from the second groove 120 in the first direction. The cross-section of the first groove 110 perpendicular to the first direction is a trapezoid, and the area of ​​the trapezoid decreases linearly along the direction from the second end to the first end.

[0043] In this embodiment, the first groove 110 preferably includes a first end with a larger opening and a second end with a smaller opening, and the first end with a larger opening is located at the end of the clamping block 100 that is away from the second groove 120 in the first direction, so that the first protrusion 210 that can be snap-fitted with the first groove 110 can limit the movement of the clamping block 100 in the first direction away from the conductor 400. Preferably, the cross-section of the first groove 110 perpendicular to the first direction is a trapezoid, and the area of ​​the trapezoid decreases linearly along the direction from the second end to the first end, so that the first protrusion 210 can smoothly move from the first end with a larger opening in the first groove 110 to the second end with a smaller opening, which is beneficial to improving the snap-fit ​​efficiency between the first protrusion 210 and the first groove 110.

[0044] Preferably, the first groove 110 and the second groove 120 have the same length in the second direction, and the cross-section of the second groove 120 perpendicular to the second direction is square, the distance of the second groove 120 in the first direction is half of the distance of the clamping block 100 in the first direction, and the cross-section of the second groove 120 perpendicular to the first direction is square.

[0045] It should be noted that in order to adapt the shape of the second groove 120 to the shape of the conductor 400, it is preferred that the cross-section of the second groove 120 perpendicular to the second direction and the cross-section perpendicular to the first direction are both square, and the lengths of the first groove 110 and the second groove 120 in the second direction are the same, and the distance of the second groove 120 in the first direction is preferably half of the distance of the clamping block 100 in the first direction.

[0046] Preferably, the second groove 120 is located in the middle of the clamping block 100 in the second direction.

[0047] In one embodiment, there is only one second groove 120 on the same clamping block 100. To prevent the clamping blocks 100 disposed up and down from being misaligned, the second groove 120 is disposed in the middle of the clamping block 100 in the second direction.

[0048] Preferably, there are a plurality of second grooves 120 , and the plurality of second grooves 120 are sequentially and spaced apart from each other on the clamping block 100 along the second direction.

[0049] In another embodiment, considering the convenience of using the clamping block 100, the clamping block 100 is set to be a long strip, and a plurality of second grooves 120 arranged in sequence along the second direction are provided on the clamping block 100. The plurality of second grooves 120 are used to fix the plurality of conductors 400, which can meet the needs of single-phase multiple copper bars or aluminum bars. The connecting block 200 can also be made into different width specifications. Whether it is single-phase multiple rows, multi-phase single row or multi-phase multiple rows, the corresponding requirements can be met by the arrangement and combination of different types of clamping blocks 100. The connecting block 200 can also be designed according to the needs of different phase spacings, so that users can select and use it more conveniently, which is simpler and more efficient.

[0050] Preferably, the trapezoid is an isosceles trapezoid, and the isosceles trapezoid includes a longer base and a shorter top, the base and the top are parallel, and the base is located at one end of the clamping block 100 in the second direction, the first groove 110 passes through the clamping block 100 along the first direction, and the first groove 110 and the first protrusion 210 are clearance fit.

[0051] It can be understood that the trapezoid is preferably an isosceles trapezoid, and the first groove 110 is designed as a symmetrical structure to facilitate the installation of the first protrusion 210 that matches the first groove 110 to avoid reverse installation. Preferably, the first groove 110 and the first protrusion 210 are clearance fit, so that the loading and unloading efficiency of the clamping block 100 and the connecting block 200 is higher, while reducing wear during the loading and unloading process.

[0052] In addition, the clamping block 100 and the connecting block 200 are both cut from block structures of the same height in the first direction, so that the end surfaces of the clamping block 100 and the connecting block 200 perpendicular to the first direction are flat after being clamped by the first groove 110 and the first protrusion 210.

[0053] In one embodiment, the angle between the first groove 110 and the overlap line inside the clamping block 100 and the first direction is preferably 15 degrees, so that the smaller end of the first protrusion 210 can be inserted into the larger first end of the first groove 110. In addition, in the trapezoidal cross section of the first groove 110 perpendicular to the first direction, the area of ​​the largest trapezoidal cross section is preferably twice the area of ​​the smallest trapezoidal cross section, and the bottom angle of the isosceles trapezoid is preferably 45 degrees, so as to avoid the bottom angle of the isosceles trapezoid being too large or too small to affect the connection strength between the first groove 110 and the first protrusion 210.

[0054] Preferably, each connecting block 200 is provided with a through hole 220 extending along the first direction, and the through hole 220 is located in the middle of the connecting block 200 in the second direction, the connecting member 300 is passed through two through holes 220 spaced apart along the first direction, and the fixing member is sleeved on the outer periphery of the connecting member 300 to limit the two connecting blocks 200 passed through the connecting member 300 from detaching from each other.

[0055] It should be noted that the through hole 220 for the connector 300 to pass through is located in the middle of the connecting block 200 in the second direction, so that the distance between the connector 300 and the two nearest second grooves 120 can be equal after the connector 300 passes through, thereby avoiding the distance between the connector 300 and the conductor 400 being too close. At the same time, insulating material can be added on the periphery of the connector 300 to increase the conductive stability of the entire device.

[0056] Preferably, the connecting member 300 and the fixing member are threadedly connected.

[0057] In this embodiment, through the threaded connection between the connecting member 300 and the fixing member, the clamping block 100 and the connecting block 200 can be easily disassembled and used repeatedly, saving the use cost. The connecting member 300 can also be set as a threaded rod body, and the fixing member is sleeved on both ends of the connecting member 300 to realize its function of limiting the distance between the connecting blocks 200.

[0058] Preferably, the corners of the clamping block 100 and the connecting block 200 are rounded.

[0059] In addition, the corners of the clamping block 100 and the connecting block 200 are preferably rounded. The rounded corners can prevent the conductor 400 from wearing each other when installed in the second groove 120, and can reduce unnecessary wear of the clamping block 100 and the connecting block 200 during installation.

[0060] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
