[0029] Example 1

[0030] Reference Figure 1 The present embodiment provides a quickly replaceable screen-top small busbar base, including a fixing assembly 100, including a base 101, the base 101 is fixed by a cross bar 102, the base 101 is divided into two upper and lower parts by an insulating plate 101a, a conductive sheet 103 is provided under the insulating plate 101a, and the conductive sheet 103 is electrically connected to the terminal block 104; a clamping assembly 200, including a base 201 arranged above the insulating plate 101a, and a pressing block 202 is slidably connected to the base 201.

[0031] Specifically, the crossbar 102 is disposed on the top of the cabinet and fixed to the top boundary of the cabinet by bolts. The base 101 is disposed on the crossbar 102 and is divided into upper and lower regions by an insulating plate 101a. The upper region is used to place the clamping assembly 200, and the lower region of the base 101 is used to fix the conductive sheet 103.

[0032] Preferably, the entire base 101 and the clamping assembly 200 are made of insulating materials, which can prevent workers from getting electric shocks during maintenance and ensure the personal safety of the workers.

[0033] Furthermore, the conductive sheet 103 is a metal conductive material, and the conductive sheet 103 is connected to the terminal block 104 through the wire 105. When the small busbar is fixed on the base through the clamping assembly 200, the small busbar is electrically connected to the conductive sheet 103. The current transmitted by the small busbar can be transferred to the terminal block 104 through the conductive sheet 103. The terminal block 104 is arranged inside the cabinet. Therefore, in the subsequent maintenance process, the staff can complete the maintenance of the small busbar by checking the wires connected to the terminal block 104. There is no need to climb to the top of the cabinet to inspect the small busbar on the top of the cabinet, which saves the step of climbing and greatly improves the efficiency of maintenance. It can also prevent electric shock accidents and ensure the personal safety of the staff.

[0034] Specifically, the groove provided on the base 201 is consistent with the shape of the pressing block 202, and the pressing block 202 is movably connected to the base 201. The groove on the base 201 can be continuously filled by moving the pressing block 202 until the pressing block 202 presses the small busbar placed on the base 201 to fix the small busbar, and the size of the groove can be adjusted by moving the pressing block 202, so as to clamp the small busbars of different diameters, thereby improving the application range of the device while realizing rapid disassembly and assembly of the small busbar.

[0035] Example 2

[0036] Reference Figure 2-4, which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that: the base 101 is H-shaped, the insulating plate 101a is horizontally placed between the two vertical plates 101b, the insulating plate 101a is provided with partitions 101a-1 at equal intervals, one side of the partition 101a-1 is provided with a conductive groove 101a-2, and a vertical plate 101b is also provided with a conductive groove 101a-2, and the base 101 is provided with positioning seats 101c at both ends, and the positioning seats 101c are inserted into the adjusting bolts 101d, and the adjusting bolts 101d are sleeved with Spring 101d-1, thread 101d-2 is provided below spring 101d-1, plug rod 101d-3 is provided at the bottom of adjusting bolt 101d, elastic member 101d-4 is symmetrically provided on plug rod 101d-3, elastic member 101d-4 is provided with downward inclined surface 101d-4a, and curved surface 101d-4b is provided at the junction of inclined surface 101d-4a and one side of elastic member 101d-4; lifting hole 102a is provided on cross bar 102, and lifting hole 102a corresponds to the position of positioning seat 101b one by one, and lifting hole 102a is provided on cross bar 102. 02a is provided with a lifting bolt 102b; a socket 102b-1 is provided in the lifting bolt 102b, a slot 102b-2 is symmetrically opened on the inner wall of the socket 102b-1, a gradient groove 102b-3 is provided on one side of the slot 102b-2, the slot 102b-2 is connected to the gradient groove 102b-3, and the threads 101d-2 of the lifting bolt 102b and the adjusting bolt 101d are in opposite directions; the conductive sheet 103 is arched, and a connecting sheet 103a is provided at one end of the conductive sheet 103, and the connecting sheet 103a is embedded in the conductive groove 101a-2, and the conductive sheet 103 is provided with a connecting sheet 103a. The conductive sheet 103 is fixed to the base 101 by a positioning bolt 103b, and a spring washer 103c is sleeved on the positioning bolt 103b; the terminal block 104 is provided with interfaces 104a, and the number of interfaces 104a corresponds to the number of conductive sheets 103. A toggle member 104b is provided at the interface 104a, and a pressing piece 104c is provided in the interface 104a. The conductive sheet 103 and the terminal block 104 are connected by a wire 105, one end of the wire 105 is sleeved on the positioning bolt 103b, and the other end of the wire 105 is connected to the terminal block 104.

[0037] Specifically, the insulating plate 101a divides the base 101 into two upper and lower areas. The structure of the partition 101a-1 is consistent with the structure of the vertical plate 101b. The partition 101a-1 on the insulating plate 101a passes through the two areas at the same time and divides each area into several independent areas. Each independent area above the insulating plate 101a is used to place the clamping assembly 200, and each independent area below the insulating plate 101a is used to fix the conductive sheet 103.

[0038] Preferably, the positioning seat 101c is a component used to fix the base 101, and the distance between the two positioning seats 101c is consistent with the distance between the two lifting holes 102a on the cross bar 102. Since a lifting bolt 102b is provided in the lifting hole 102a of the cross bar 102, the adjusting bolt 101d inserted in the positioning seat 101c is on the same axis as the lifting bolt 102b. When the base 101 is fixed, the insert rod 101d-3 at the bottom of the adjusting bolt 101d needs to be inserted into the socket 102b-1 of the lifting bolt 102b. The elastic member 101d-4 on the insertion rod 101d-3 will be pressed into the insertion rod 101d-3 under pressure. Therefore, during the process of inserting the insertion rod 101d-3 into the insertion hole 102b-1, the elastic member 101d-4 is continuously pressed back into the insertion rod 101d-3 through the contact between the inclined surface 101d-4a and the side wall of the insertion hole 102b-1. When the insertion rod 101d-3 is fully inserted, the elastic member 101d-4 pops out again and embeds into the slot 102b-2 to fix the base 101.

[0039] Furthermore, when the adjusting bolt 101d is fully inserted into the socket 102b-1, the thread 101d-2 just disengages from the positioning seat 101c. At this time, rotating the adjusting bolt 101d will not cause it to rise or fall. Even if the elastic member 101d-4 is not in the same position as the slot 102b-2, after the insertion rod 101d-3 is fully inserted, it is only necessary to slightly rotate the adjusting screw 101d to adjust the position of the elastic member 101d-4, so that the elastic member 101d-4 can be embedded in the slot 102b-2 to complete the fixation of the base 101; in the process of inserting the adjusting bolt 101d into the socket 102b-1, the spring 101d-1 contacts the upper surface of the positioning seat 101c and is continuously compressed.

[0040] Furthermore, a gradient groove 102b-3 with a uniformly varying groove depth is provided on one side of the groove 102b-2, and the groove depth of the gradient groove 102b-3 decreases as it moves away from the groove 102b-2. A transition surface is also provided between the slot 102b-2 and the gradient groove 102b-3. After the elastic member 101d-4 is inserted into the slot 102b-2, the arc surface 101d-4b contacts the transition surface. Due to the restriction of the transition surface, the elastic member 101d-4 will be restricted in the slot 102b-2 in the absence of external force. When the adjusting bolt 101d is subjected to a force in the opposite direction to the thread 101d-2, the arc surface 101d-4b contacts the transition surface to make the lifting bolt 102b rotate. When the lifting bolt 102b drops to the bottom of the lifting hole 102a and cannot continue to rotate, the elastic member 101d-4 is pressed back to the insertion rod 101d-3, thereby crossing the transition surface and entering the gradient groove 102b-3.

[0041] In this embodiment, the adjusting bolt 101d is rotated along the direction of the thread 101d-2 so that the bottom of the adjusting bolt 101d is inserted into the socket 102b-1 to fix the base 101. After the base is fixed, due to the influence of many factors, the heights of adjacent cabinets may be different. At this time, the small busbar is easily bent when fixed on the top of the cabinet, and may even break under the influence of a long time, which has a significant impact on the normal operation of the unit. However, through our fixing assembly 100, when the cabinet heights are different, the adjusting bolt 101d on the fixing assembly 100 at a lower height is further rotated along the direction of the thread 101d-2. Since the thread direction of the lifting bolt 102b is opposite to that of the adjusting bolt 101d, the lifting bolt 102b will rise under the drive of the adjusting bolt 101d through the restriction of the lifting bolt 102b by the elastic member 101d-4, and the lifting bolt 102b can lift the base 101 upward through the lifting bolt 102b, thereby adjusting the position of the small busbar to ensure that the small busbar can be set in parallel on the top of each cabinet.

[0042] When the base 101 needs to be removed from the cross bar 102, it is only necessary to rotate the adjusting bolt 101d in the opposite direction of the thread 101d-2. At this time, the inclined surface of the elastic member 101d-4 presses against the transition surface, driving the lifting bolt 102b to descend until the lifting bolt 102b drops to the lowest point. The transition surface is in a fixed state, and continuing to rotate the adjusting bolt 101d will cause the elastic member 101d-4 to be partially pressed back into the insertion rod 101d-3, thereby crossing the transition surface and entering the gradient groove 102b-3. As the adjusting bolt 101d continues to rotate, the elastic member 101d-4 in the gradient groove 102b-3 is gradually pressed back into the insertion rod 101d-3 until the elastic member 103d-4 is disengaged from the groove, completing the separation of the base 101 and the cross bar 102.

[0043] Due to the different heights of the cabinets, the small busbar on the top of the cabinet may be bent, and the mechanical fatigue caused by long-term bending may cause cracks or even breakage of the small busbar, which has a significant impact on the operation of the unit. By setting the fixing component 100, the position of the small busbar can be adjusted to ensure that the small busbar is set parallel to the top of the cabinet to prevent the small busbar from bending.

[0044] Example 3

[0045] Reference Figure 5, which is the third embodiment of the present invention, and this embodiment provides a quickly replaced screen top small busbar base. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: the base 201 is provided with a trapezoidal groove 201a, and a wiring groove 201b is provided on the vertical side wall of the trapezoidal groove 201a, and a through hole 201c is provided at the bottom of the wiring groove 201b, and a conductive member 203 is provided in the through hole 201c, and a guide groove 201d is provided on the inclined side wall of the trapezoidal groove 201a, and threaded holes 201e are provided on both sides of the guide groove 201d; the pressing block 202 is a trapezoidal block, and the top of the pressing block 202 is symmetrically provided with straight slots 202a, and the straight slots 202a passes through the pressure block 202, and a moving groove 202b is provided between the two straight grooves 202a; a fastening bolt 202c is inserted into the straight groove 202a, a driven tooth 202c-1 is provided on the top of the fastening bolt 202c, a spring gasket 103c is sleeved on the fastening bolt 202c, an active tooth 202d is inserted into the moving groove 202b, a hexagonal hole 202d-1 is provided on the top of the active tooth 202d, and a sliding column 202d-2 is provided at the bottom of the active tooth 202d; the conductive member 203 includes a conductor 203a, a return spring 203b sleeved on the conductor 203a, and a pressing sheet 203c located at the top of the conductor 203a.

[0046] Specifically, the guide groove 201d is provided to limit the moving path of the pressing block 202, thereby ensuring that the pressing block 202 always keeps moving horizontally.

[0047] Furthermore, the driven teeth 202c-1 mesh with the driving teeth 202d, and the driven teeth 202c-1 on both sides can be driven to rotate by rotating the driving teeth 202d, thereby rotating the fastening bolts 202c. Since the fastening bolts 202c pass through the pressing block 202 and are inserted into the threaded holes 201e of the base 201, the fastening bolts 202c will squeeze the pressing block 202 during the process of rotating and moving downward, so that the pressing block 202 moves downward along the guide groove 201d. During the process of the fastening bolts 202c pressing downward, the pressing block 202 will move horizontally, thereby causing the driving teeth 202d to move synchronously in the moving groove 202b.

[0048] Preferably, when the conductive member 203 is not subjected to external force, the pressing piece 203c extends out of the wiring slot 201b, and the conductive member 203 does not contact the connecting piece 103a. When the pressing block 202 is adjusted to clamp the small busbar by the fastening bolt 202c, the small busbar placed in the wiring slot 201b presses the pressing piece 203c under the action of the pressing block 202, so that the conductive member 203 contacts the connecting piece 103a, and the current on the small busbar is transmitted to the wiring row 104 arranged inside the cabinet.

[0049] In this embodiment, the small busbar is placed in the wiring slot 201b, and the fastening bolt 202c is driven to rotate by rotating the active tooth 202d, thereby driving the pressing block 202 to move. By adjusting the moving distance of the pressing block 202, small busbars with different diameters can be clamped, thereby improving the applicable range of the clamping assembly 200. After clamping, the spring gasket 103c can prevent the fastening bolt 202c from loosening, thereby ensuring reliable clamping of the small busbar.

[0050] By providing the conductive member 203, it is possible to detect whether the small busbar is firmly installed and whether the small busbar is in good contact with the terminal. By providing the terminal block 104 extending from the base 101, the signal transmitted by the small busbar can be synchronized to the wire 105 connected in the terminal block 104. When the small busbar is to be inspected, the staff does not need to inspect the small busbar on the top of the cabinet, but only needs to inspect the wire 105 connected to the terminal block in the cabinet. In addition, the space on the top of the cabinet is small, and the inspection work is difficult to carry out. In this way, the convenience and safety of the inspection link are improved.
