[0043] As shown in Figures 1-8 , the busbar fixing device comprises a busbar clamp 1 and a fixing piece 2. The busbar clamp 1 is provided with a fixing channel 11, and the inner side wall of the fixing channel 11 is provided with a plurality of clamping pieces 12 along the height direction of the fixing channel 11. The fixing piece 2 comprises a fixing part 21 and a first clamping part 22 arranged on the opposite sides of the fixing part 21, the fixing part 21 is located in the fixing channel 11 and can move along the height direction of the fixing channel 11, and the first clamping part 22 can be clamped to the corresponding clamping piece 12.

[0044] Specifically, the height direction of the fixing channel 11 is the AB direction in the figure, and the width direction of the fixing channel 11 is the CD direction in the figure. The busbar clamp 1 has a fixing channel 11 for fixing the busbar 100, which has excellent conductivity as a conductor, and the thinnest thickness is only 3mm. The improved structure of the ultra-thin structure increases the surface area, while ensuring the carrying capacity, the cross-sectional area is greatly reduced. The two side walls of the fixing channel 11 are provided with a plurality of clamping pieces 12, and the plurality of clamping pieces 12 form a sawtooth structure, which can ensure the structural strength of the busbar clamp 1 while not damaging the integrity of the busbar clamp 1. The fixing piece 2 is made of high-strength insulating materials, such as high-molecular materials such as polyethylene and polypropylene, and non-metallic materials such as glass and ceramic. The fixing piece 2 has high strength, so that after the current is turned on, the fixing piece 2 itself will not loosen and fall off, and at the same time, the fixing piece 2 has a certain plasticity, which can ensure that the fixing piece 2 can be smoothly clamped into the busbar clamp 1. The opposite sides of the fixing part 21 are provided with the first clamping part 22, and the first clamping part 22 is an elastic structure, and the first clamping part 22 is integrally formed with the fixing part 21.

[0045] The fixing part 21 is placed in the fixing channel 11 and can move along the height direction of the fixing channel 11. After adjusting the position of the fixing part 21 in the fixing channel 11, the fixing part 21 is located at the top end of the busbar clamp 1. The first clamping part 22 on both sides is pressed by hand or tool, and the fixing part 21 slides up and down in the fixing channel 11 along the height direction of the busbar clamp 1. When the fixing part 21 abuts against the busbar 100, the first clamping part 22 is loosened, the first clamping part 22 is clamped to the corresponding clamping piece 12 and is fixed relative to the busbar clamp 1, so as to fix the busbar 100 in the height direction, and the installation stability is high. Adjusting the position of the fixing part 21 can be suitable for installation of busbars 100 of different heights, improving the universality of the fixing piece 2, reducing the number of busbar clamps 1, reducing the mold cost, and thus reducing the cost of the whole fixing device. Alternatively, for busbars 100 of different heights, in addition to the above-mentioned change of the installation position of the fixing piece 2, the number of fixing pieces 2 can also be changed to match the installation of busbars 100 of different heights.

[0046] Further, referring to Figure 2 and Figure 8The bus fixing device further comprises a clamping piece 3 which is detachably connected to the fixing portion 21 and is used to clamp the bus 100 in the width direction of the fixing channel 11. Specifically, the clamping piece 3 is detachably connected to the fixing portion 21. In some embodiments, when the thickness of the bus 100 is slightly smaller than the width of the fixing channel 11, the clamping piece 3 is detached from the fixing piece 2, and the bus 100 is fixed only under the action of the fixing piece 2. When the thickness of the bus 100 is much smaller than the width of the fixing channel 11, the clamping piece 3 is installed on the fixing portion 21, and the two sides of the bus 100 are clamped under the action of the clamping piece 3. Different clamping pieces 3 are replaced for fixing buses 100 of different thicknesses, which further improves the versatility of the fixing piece 2, greatly reduces the number of bus clamps 1, reduces the mold cost, and thus reduces the cost of the entire fixing device.

[0047] Further, referring to Figure 1 and Figure 8 The fixing portion 21 is further provided with a second clamping portion 23 on each side, and the second clamping portion 23 can be clamped to the corresponding clamping piece 12. Specifically, the second clamping portion 23 is an elastic structure, and the second clamping portion 23 is integrally formed with the fixing portion 21. The fixing piece 2 has two clamping portions, i.e., the first clamping portion 22 and the second clamping portion 23. The second clamping portion 23 is located below the first clamping portion 22. The upper portion of the fixing piece 2 is clamped and fixed in the clamping piece 12 of the bus clamp 1 through the first clamping portion 22, and at the same time, the lower portion of the fixing piece 2 is clamped and fixed in the clamping piece 12 of the bus clamp 1 through the second clamping portion 23. The fixing piece 2 is installed in the fixing channel 11 of the bus clamp 1 in a double-fixing manner, which further ensures the installation stability and reliability of the fixing piece 2. Alternatively, the fixing piece 2 can be fixed in a single-sided clamping or double-sided clamping manner, and the clamping piece 12 with a sawtooth structure is arranged on one side wall or two side walls of the fixing channel 11. Alternatively, the structure of the clamping piece 12 is changed, and the number of clamping pieces 12 is adjusted, which are all within the protection scope of the present embodiment.

[0048] Further, referring to Figure 2The clamping piece 3 comprises a clamping portion 31, a sliding portion 32 and a third clamping portion 33. The opposite sides of the clamping portion 31 are respectively provided with the third clamping portion 33, which can be clamped to the corresponding clamping piece 12. The sliding portion 32 is arranged at one end of the clamping portion 31. The end of the fixing portion 21 of the fixing piece 2 is provided with a sliding groove 211. The sliding portion 32 is movably inserted into the sliding groove 211. The other end of the clamping portion 31 is provided with a clamping groove 311. The groove width of the clamping groove 311 is matched with the width of the busbar 100. The busbar 100 is inserted and clamped into the clamping groove 311. Specifically, the third clamping portion 33 is of an elastic structure and is integrally formed with the clamping portion 31. In some embodiments, the longitudinal cross-sectional shape of the sliding groove 211 can be T-shaped structure. The sliding portion 32 matched therewith is also T-shaped structure. The sliding portion 32 is slidably connected with the sliding groove 211 of the fixing portion 21, so that the clamping piece 3 is installed and fixed with the fixing piece 2. According to the thickness matching requirement of the busbar 100 and the width of the fixing channel 11, the clamping piece 3 can be disassembled or installed to clamp and fix the busbar 100. The clamping portion 31 is provided with the clamping groove 311. The width of the clamping groove 311 corresponds to the thickness of the busbar 100. That is, according to the thickness of different busbars 100, the corresponding clamping piece 3 with the matching clamping groove 311 is selected. The sliding portion 32 is inserted into the sliding groove 211 of the fixing portion 21. Under the action of the clamping portion 31, the two sides of the busbar 100 are clamped and fixed. At the same time, the third clamping portion 33 on both sides of the clamping portion 31 is clamped in the corresponding clamping piece 12, which is used for clamping and fixing the busbar 100.

[0049] Further, with continued reference to Figure 1 、 Figure 2 and Figure 4In some embodiments, the inner side wall of the fixed channel 11 is provided with protrusions 5, a sliding piece 4 is arranged between the fixed portion 21 and the protrusions 5, one end of the sliding piece 4 is detachably connected with the fixed portion 21, and the other end of the sliding piece 4 is in contact with the protrusions 5. Specifically, in order to increase the heat dissipation area of the bus bar clamp 1, a plurality of protrusions 5 are arranged on the inner side wall of the fixed channel 11 along the height direction of the fixed channel 11, and the plurality of protrusions 5 are arranged side by side with the clamping piece 12 of the zigzag structure. The fixed portion 21 is also provided with a mounting groove 212, and the sliding piece 4 is inserted into the mounting groove 212. After the fixed piece 2 fixes the bus bar 100 in the height direction, a sliding piece 4 matching the thickness of the protrusion 5 is selected, so that the sliding piece 4 and the protrusion 5 can be mutually attached, thereby increasing the stability of the fixed piece 2 in the fixed channel 11. If the bus bar clamp 1 does not consider heat dissipation, the inner side wall of the fixed channel 11 is flat without protrusions 5, and the sliding piece 4 does not need to be arranged on the fixed portion 21. Alternatively, the inner side wall of the fixed channel 11 is provided with protrusions 5 of different thicknesses, and the sliding piece 4 is detachably connected with the fixed portion 21 through the mounting groove 212, so as to replace the sliding piece 4 of the matching thickness. Alternatively, corresponding to the protrusions 5 arranged on the inner side wall of the fixed channel 11, one side of the fixed piece 2 is provided with sliding pieces 4 of two different thicknesses along the height direction of the fixed channel 11, which can adapt to the two corresponding thicknesses of the protrusions 5, thereby reducing the frequency of replacement of the sliding piece 4 by the staff.

[0050] Further, referring to Figure 3 and Figure 5 , the side wall of one end of the fixed channel 11 in the height direction is provided with a fixed groove 13, the fixed groove 13 is in a stepped structure, the fixed groove 13 is used for inserting one end of the bus bar 100, and the fixed piece 2 or the clamping piece 3 is used for connecting the other end of the bus bar 100. Specifically, the fixed groove 13 in a stepped structure is arranged at the bottom of the bus bar clamp 1. When the thickness of the bus bar 100 is less than the width of the fixed channel 11, one end of the bus bar 100 is inserted into the fixed groove 13, and the other end of the bus bar 100 is clamped and fixed by the clamping piece 3. For bus bars 100 of different thicknesses, the fixed groove 13 has a plurality of stepped grooves of different widths combined to adapt to the installation of bus bars 100 of different thicknesses, thereby reducing the number of bus bar clamps 1 and the mold cost, and thus reducing the cost of the entire fixing device.

[0051] Further, referring to Figure 6 and Figure 7The busbar fixing device further comprises a cushion block 6, which is clamped between the busbar 100 and the inner side wall of the fixing channel 11 in the width direction of the fixing channel 11. The cushion block 6 is provided with a fourth clamping part 61, which is clamped and matched with the clamping piece 12. Specifically, the fourth clamping part 61 is provided with a plurality of fourth clamping parts 61, which form a sawtooth structure. The fourth clamping part 61 and the opening direction of the clamping piece 12 are oppositely arranged, so that the fourth clamping part 61 can be clamped and matched with the clamping piece 12. The cushion block 6 is provided with a boss 7 and a buckle 8. The number of buckles 8 is at least two. The two buckles 8 are arranged at the upper and lower edges of the cushion block 6 in the height direction of the fixing channel 11. The boss 7 is located between the two buckles 8 on the cushion block 6. The boss 7 can increase the strength of the overall cushion block 6. The inner side wall of the fixing channel 11 is provided with a mounting hole 14 and a connecting groove 15. Along the width direction of the fixing channel 11, the connecting groove 15 is connected between the two adjacent clamping pieces 12. The number of connecting grooves 15 is two. The two connecting grooves 15 correspond to the two buckles 8 on the cushion block 6 one by one. The mounting hole 14 is located between the two connecting grooves 15 and corresponds to the boss 7. The boss 7 is inserted into the mounting hole 14, and the buckle 8 is clamped in the connecting groove 15, so that the installation of the cushion block 6 is more reliable. According to the thickness of the busbar 100, whether to install the cushion block 6 and the size of the cushion block 6 are selected. When the thickness of the busbar 100 is equal to the width of the fixing channel 11, the clamping piece 3 and the cushion block 6 are not needed. Only the busbar 100 is fixed and clamped by the fixing piece 2. When the thickness of the busbar 100 is less than the width of the fixing channel 11, the clamping piece 3 and the stepped structure of the fixing groove 13 are used to clamp the busbar 100 in the vertical direction. At the same time, through the action of the boss 7 inserted into the mounting hole 14 and the buckle 8 clamped in the connecting groove 15, the cushion block 6 is fixed between the inner side wall of the fixing channel 11 and the side wall of the busbar 100, which is used for the fixed clamping of the busbar 100. Preferably, a plurality of cushion blocks 6 are arranged between the busbar 100 and the inner side wall of the fixing channel 11 in the height direction of the fixing channel, which further improves the stability of the busbar 100 relative to the busbar clamp 1. By replacing the cushion block 6 and the clamping piece 3 of different sizes, the busbar 100 of different thicknesses can be fixed, which greatly reduces the number of busbar clamps 1 and the mold cost.

[0052] Further, referring to Figure 7 and Figure 8 The number of fixing channels 11 is multiple, and the multiple fixing channels 11 are distributed in a matrix. Specifically, the busbar clamp 1 can fix and clamp busbars 100 of different heights and thicknesses through the multiple fixing channels 11, which has a wide range of applications.

[0053] Further, referring to Figure 3The material of the bus clamp 1 is a pressure-induced color-changing material. When the bus clamp 1 is damaged, such as cracking, the bus clamp 1 will change color obviously, so that the damaged position of the bus clamp 1 can be found in time, and the bus clamp 1 can be repaired or replaced in time. Alternatively, materials that can meet the requirements of high strength, high temperature resistance, and obvious color change at the damaged position can be used.

[0054] The method for using the bus fixing device is as follows:

[0055] For example, when the width of the fixing channel 11 of the bus clamp 1 is 6 mm, and the thickness of the bus 100 is 6 mm, the bus 100 is placed in the fixing channel 11, the bottom of the bus 100 is clamped in the fixing groove 13 with a width of 6 mm, the fixing groove 13 is used to fix the bus 100 in the vertical direction, and the height of the bus 100 is much smaller than the height of the fixing channel 11. Then, the fixing part 21 is placed in the fixing channel 11 and can move along the height direction of the fixing channel 11. After adjusting the position of the fixing part 21 in the fixing channel 11, the fixing part 21 is located at the top end of the bus clamp 1. The first clamping part 22 on both sides of the fixing part 21 is pressed by hand or a tool. The fixing part 21 slides in the fixing channel 11 along the height direction of the bus clamp 1. When the fixing part 21 abuts against the top of the bus 100, the first clamping part 22 is released, and the first clamping part 22 clamps the corresponding clamping piece 12 relative to the bus clamp 1 to fix the bus 100 in the height direction, and the installation stability is high. Adjusting the position of the fixing part 21 can be suitable for the installation of buses 100 with different heights. When the thickness of the bus 100 is 4 mm, the bus 100 is placed in the fixing channel 11, the bottom of the bus 100 is clamped in the fixing groove 13 with a width of 4 mm, the clamping part 3 is installed on the fixing part 2, the width of the clamping groove 311 of the clamping part 3 is 4 mm, the first clamping part 22 on both sides of the fixing part 21 is pressed, the fixing part 21 slides in the fixing channel 11 along the height direction of the bus clamp 1, so that the clamping part 3 can clamp the two sides of the bus 100, and at the same time, the first clamping part 22 can clamp the clamping piece 12, and the fixing part 2 is fixed relative to the bus clamp 1. Then, the spacer 6 is arranged between the bus 100 and the inner side wall of the fixing channel 11, that is, the two sides of the bus 100 are both provided with the spacer 6, the thickness of the spacer 6 is 1 mm, and under the action of the boss 7 and the buckle 8, the spacer 6 is fixed between the inner side wall of the fixing channel 11 and the side wall of the bus 100 in the width direction of the fixing channel 11, and is used for clamping and fixing the bus 100. The bus fixing device can clamp and fix the bus 100, and is suitable for fixing buses 100 with different heights and different thicknesses, can reduce the number of bus clamps 1 and the mold opening cost, and thus can reduce the cost of the entire fixing device. Alternatively, the installation principle is the same, the fixing mode of the fixing part 2 is changed to be fixed by the first clamping part 22 and the second clamping part 23, the bottom of the bus clamp 1 is no longer provided with the clamping part 3, and the spacer 6 is added to the bottom of the bus clamp 1 for fixing.
