Description

Technical Field

[0001] The invention relates to the technical field of busbar devices, and in particular to a copper busbar connection structure. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in busbars have emerged as a new type of distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in high-current transmission. At the same time, due to the use of new technologies and processes, the contact resistance and temperature rise of the connection points at both ends of the busbar and the plug-in points of the branch ports are greatly reduced. High-quality insulating materials are used in the busbar duct, thereby improving the safety and reliability of the busbar duct and making the entire system more perfect.

[0003] The busbar is a system composed of metal plates as protective shells, conductive copper bars, insulating materials and related accessories. It can be made into standard length sections, with plug-in junction boxes at intervals, or it can be made into a feeder-type closed busbar without a junction box in the middle. The busbar brings great convenience to power feeding and installation and maintenance.

[0004] The conductive copper bars in the existing busbars do not have the function of electrical conduction, and the existing conductive copper bars are usually straight or parallel spliced, and have a narrow application range. Therefore, the conductive copper bars in the existing busbars cannot be electrically conductive and cannot be bent and installed, which has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a copper busbar connection structure, which solves the technical problems that the conductive copper busbar in the existing busbar cannot be electrically conductive and cannot be bent for installation.

[0006] The present invention provides a copper bar connection structure, comprising an L-shaped copper bar, a first connector, a second connector, a first conductor and a second conductor, wherein the bent copper bar comprises a first copper bar and a second copper bar connected to each other;

[0007] The first conductor is disposed inside the first connector, and the second conductor is disposed inside the second connector;

[0008] The first connector is sleeved on the outer surface of the first copper busbar, and the first copper busbar is electrically connected to the first conductor;

[0009] The second connector is sleeved on the outer surface of the second copper busbar, and the second copper busbar is electrically connected to the second conductor.

[0010] Preferably, the first connector and the second connector are both provided with a housing accommodating cavity;

[0011] The housing accommodating cavity forms a space for accommodating the connector conductor.

[0012] Preferably, a copper bar holding groove is provided inside the connector conductor;

[0013] The copper bar holding groove forms a space for accommodating the first power connection copper bar and the second power connection copper bar.

[0014] Preferably, a first pressing protrusion and a second pressing protrusion are respectively provided on both sides of the inner wall of the copper bar clamping groove.

[0015] Preferably, the first pressing protrusion and the second pressing protrusion are both integrally formed with the copper bar holding groove.

[0017] Preferably, the first anti-slip protrusion and the second anti-slip protrusion are both integrally formed with the copper bar holding groove.

[0018] A copper bar connection structure provided by the present invention can be suitable for a busbar device that is bent and installed by designing a first power connection copper bar and a second power connection copper bar as L-shaped connection copper bars that are connected to each other. The first power connection copper bar and the second power connection copper bar are both provided with connectors on the outside, and are electrically connected to a conductor arranged inside the connector through the connector, so that electrical conduction can be achieved, thereby expanding its application range.

[0031] The second copper busbar 1 is sleeved with the first connector 4 , so that the first copper busbar 1 is electrically connected to the connector conductor 62 in the first connector 4 .

[0032] Furthermore, a shell accommodating cavity 611 is disposed in each of the first connector 4 and the second connector 5 , and the shell accommodating cavity 611 forms a space for accommodating the connector conductor 62 .

[0033] For further information, see Figure 3 and Figure 4 , a copper bar holding groove 621 is provided inside the connector conductor;
