Description

Technical Field

[0001] This utility model belongs to the field of copper busbar connection, specifically a copper busbar connection structure. Background Technology

[0002] Copper busbars, also known as copper busbars or copper current busbars, are long conductors made of copper with a rectangular or chamfered rectangular cross-section. They serve to transmit current and connect electrical equipment in circuits and are generally used in distribution cabinets. When installing copper busbars in a distribution cabinet, the main copper busbar serves as the main conductor of the distribution cabinet and is fastened to the output terminal of the incoming circuit breaker with bolts. Then, the current transformer is installed on the main copper busbar. Next, branch copper busbars are installed on multiple components. Finally, horizontal copper busbars are installed between the main copper busbar and the multiple branch copper busbars to ensure the continuity of the current path.

[0003] However, when connecting the main copper busbar and multiple branch copper busbars to the horizontal copper busbar, a corresponding number of mounting holes need to be pre-drilled on the horizontal copper busbar according to the number of main copper busbars and branch copper busbars to be installed. The positions of the multiple mounting holes need to correspond to the distribution positions of the branch copper busbars on the components and the main copper busbars on the circuit breaker. Therefore, the number, spacing and position of the mounting holes need to be completely determined during the processing stage of the horizontal copper busbar. If the layout of the components is adjusted later (such as the number of components increases or decreases, causing the number of branch copper busbars to increase or decrease simultaneously, or the usage position of the components is changed), the horizontal copper busbar needs to be reprocessed, making the connection between the branch copper busbars and the horizontal copper busbar more troublesome and time-consuming.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a copper busbar connection structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a copper busbar connection structure.

[0006] A copper busbar connection structure includes a horizontal copper busbar. The front of the horizontal copper busbar is provided with a main copper busbar and multiple branch copper busbars. The horizontal copper busbar is provided with a number of mounting components corresponding to the number of branch copper busbars and main copper busbars, which are used to install the branch copper busbars and main copper busbars on the horizontal copper busbar. The rear side of the horizontal copper busbar is provided with a positioning component for positioning the mounting components, and the bottom of the horizontal copper busbar is provided with two sets of pressing components that cooperate with the positioning component.

[0007] Preferably, the upper part of the horizontal copper busbar is provided with an installation groove, and the mounting component includes a mounting block that is slidably disposed in the installation groove. An L-shaped connecting block is provided on the upper part of the mounting block. The side of the sub-copper busbar and the main copper busbar that is close to the horizontal copper busbar is attached to the side of the connecting block that is away from the horizontal copper busbar. Both the mounting block and the connecting block are made of copper.

[0008] Preferably, the vertical cross-section of the mounting groove and the mounting block is T-shaped.

[0009] Preferably, the connecting block has an installation port for mounting the main copper busbar and the branch copper busbar, and a bolt is threaded inside the installation port. The main copper busbar and the branch copper busbar are connected to the corresponding connecting block by bolts.

[0010] Preferably, the positioning assembly includes two connecting rods symmetrically distributed on the rear side of the horizontal copper busbar, a positioning plate slidably disposed between the two connecting rods, a plurality of equally spaced toothed blocks disposed on the side of the positioning plate near the connecting block, and a spring sleeved on the outer side of the connecting rod, with the two ends of the spring connected to one side of the connecting rod and the positioning plate, respectively.

[0011] Preferably, the connecting block has multiple toothed grooves on the side near the positioning plate that mate with the toothed blocks, and the corresponding toothed blocks are inserted into the corresponding toothed grooves.

[0012] Preferably, the extrusion assembly includes a connecting shaft fixedly disposed at the bottom of the horizontal copper busbar, and an extrusion block is rotatably disposed at the bottom of the connecting shaft.

[0013] Preferably, both ends of the extrusion block near the positioning plate are rounded.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the combined use of mounting components and positioning components, allows for the reasonable installation of a corresponding number of mounting components in the mounting groove according to the installation position and quantity of the branch copper busbars and main copper busbars. It eliminates the need to pre-drill mounting holes on the horizontal copper busbars corresponding to the number and position of the branch copper busbars and main copper busbars, greatly improving the connection efficiency between the branch copper busbars and main copper busbars and the horizontal copper busbars, and enhancing the practicality of the horizontal copper busbars. At the same time, the positioning components ensure the stability of the mounting components on the horizontal copper busbars, thus ensuring the stability of the branch copper busbars and main copper busbars installed on the horizontal copper busbars.

[0016] 2. This utility model is equipped with an extrusion component. By rotating the extrusion block to extrude the positioning plate, the positioning plate can be moved to cancel the limiting lock on the connecting block. This makes it easier to adjust the position of the connecting block according to the change of the installation position of the copper busbar, and further improves the connection efficiency between the copper busbar and the horizontal copper busbar.

Detailed Implementation

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a copper busbar connection structure, including a horizontal copper busbar 1. The front of the horizontal copper busbar 1 is provided with a main copper busbar 2 and a plurality of branch copper busbars 3. The horizontal copper busbar 1 is provided with a plurality of mounting parts 4 corresponding to the number of branch copper busbars 3 and main copper busbars 2, for mounting the branch copper busbars 3 and main copper busbars 2 on the horizontal copper busbar 1. The rear side of the horizontal copper busbar 1 is provided with a positioning component 5 for positioning the mounting parts 4, and the bottom of the horizontal copper busbar 1 is provided with two sets of pressing components 6 that cooperate with the positioning component 5.

[0028] refer to Figure 1 and Figure 4 The upper part of the horizontal copper busbar 1 is provided with an installation groove 7. The mounting component 4 includes a mounting block 41 that is slidably disposed in the installation groove 7. An L-shaped connecting block 42 is provided on the upper part of the mounting block 41. The side of the sub-copper busbar 3 and the main copper busbar 2 that is close to the horizontal copper busbar 1 is in contact with the side of the connecting block 42 that is away from the horizontal copper busbar 1. Both the mounting block 41 and the connecting block 42 are made of copper. The vertical cross-section of the installation groove 7 and the mounting block 41 is T-shaped.

[0029] refer to Figure 1 , Figure 2 , Figure 3 and Figure 6The positioning component 5 includes two connecting rods 51 arranged symmetrically on the left and right sides of the rear side of the horizontal copper busbar 1. A positioning plate 52 is slidably arranged between the two connecting rods 51. Multiple toothed blocks 53 are arranged at equal intervals on the side of the positioning plate 52 near the connecting block 42. A spring 54 is sleeved on the outside of the connecting rods 51. The two ends of the spring 54 are respectively connected to one side of the connecting rod 51 and the positioning plate 52.

[0030] refer to Figure 1 , Figure 2 and Figure 3 The extrusion assembly 6 includes a connecting shaft 61 fixedly mounted at the bottom of the horizontal copper busbar 1, and an extrusion block 62 rotatably mounted on the lower outer end of the connecting shaft 61. Both ends of the extrusion block 62 near the positioning plate 52 are rounded.

[0031] When installing the mounting component 4 into the mounting slot 7, the operator can rotate the pressing block 62 to press against the positioning plate 52. The positioning plate 52, under pressure, will move backward and press against the spring 54. Rotation of the pressing block 62 will stop once one side of it is in contact with the side of the positioning plate 52. (Refer to...) Figure 5 At this time, the staff can select the corresponding number of mounting parts 4 according to the number of copper busbars 3, and then move the mounting block 41 along the mounting groove 7 to the corresponding position of the copper busbar 3, which facilitates the subsequent connection with the copper busbar 3, and there is no need to make holes in the horizontal copper busbar 1 in advance, which greatly improves the practicality of the copper busbar 3.

[0032] Meanwhile, if the layout of the components in the distribution cabinet needs to be adjusted later (such as the increase or decrease of the number of components causing the number of copper busbars 3 to increase or decrease synchronously, or the use position of the components to be changed), the number and position of the mounting parts 4 can be adjusted according to the adjusted number and position of the copper busbars 3, without the need to reprocess the horizontal copper busbars 1, thus improving the connection efficiency between the copper busbars 3 and the horizontal copper busbars 1.

[0033] refer to Figure 4 and Figure 6 The connecting block 42 has multiple toothed grooves 10 that mate with the toothed block 53 on the side near the positioning plate 52, and the corresponding toothed block 53 is inserted into the corresponding toothed groove 10.

[0034] After the mounting block 41 is moved to the position corresponding to the copper busbar 3, the pressing block 62 can be rotated to move it away from the positioning plate 52. At this time, the pressing force on the positioning plate 52 disappears, and then the elastic force of the spring 54 can drive the positioning plate 52 to reset, thereby driving the toothed block 53 to move and insert into the toothed groove 10 on the mounting block 41, realizing the limit locking of the connecting block 42 and ensuring the stability of the connecting block 42 on the horizontal copper busbar 1.

[0035] refer to Figure 4The connecting block 42 has an installation port 8 for installation with the main copper busbar 2 and the branch copper busbar 3. The installation port 8 is threaded with a bolt 9. The main copper busbar 2 and the branch copper busbar 3 are connected to the corresponding connecting block 42 by the bolt 9.

[0036] After the connecting block 42 is locked, the workers can use bolts 9 to install the sub-copper busbar 3 and the main copper busbar 2 onto the horizontal copper busbar 1, which is simple and convenient.

[0037] Working principle: When installing the main copper busbar 2 and the branch copper busbar 3 onto the horizontal copper busbar 1, first rotate the pressing block 62 to press the positioning plate 52. The positioning plate 52 moves backward under the pressure, driving the toothed block 53 to move. After one side of the positioning plate 52 is in contact with the side edge, stop rotating. At this time, select the corresponding number of mounting parts 4 according to the number of branch copper busbars 3 and main copper busbars 2, and slide the mounting block 41 along the mounting groove 7 to the position corresponding to the branch copper busbar 3. Then, rotate the pressing block 62 in the opposite direction to move it away from the positioning plate 52. The positioning plate 52 returns to its original position under the elastic force of the spring 54, driving the toothed block 53 to insert into the toothed groove 1 on the connecting block 42. Within 0, the limiting and locking of the connecting block 42 is completed. Finally, the main copper busbar 2 and the branch copper busbar 3 are tightly connected to the connecting block 42 by passing the bolt 9 through the mounting port 8 on the connecting block 42. When the layout of the components in the distribution cabinet needs to be adjusted later, the pressing block 62 is rotated again to press the positioning plate 52 to release the locking of the connecting block 42. The number and position of the mounting parts 4 are adjusted as needed. The above locking and connection steps are repeated to quickly complete the reconnection of the branch copper busbar 3 and the horizontal copper busbar 1. There is no need to pre-drill holes or re-process the horizontal copper busbar 1, which greatly improves the efficiency of installing the main copper busbar 2 and the branch copper busbar 3 on the horizontal copper busbar 1.
