Description

Technical Field

[0001] The invention relates to an electrical connector, in particular to an insulating pad and a busbar flexible connector using the insulating pad. Background Art

[0002] The terminal busbar is usually a power distribution device for power terminals composed of copper conductors and aluminum alloy shells. It can supply power to specific equipment through matching plug-in boxes and other devices. Especially for network cabinets in data centers, the terminal busbar power supply method has increasingly replaced the traditional cabinet cable power supply method. This power supply method can provide a larger power output capacity and has strong expansion capabilities. At the same time, it also saves valuable space resources after replacing the cabinet, allowing users to deploy more network cabinets. Therefore, it has become a trend to adopt the terminal busbar power supply method in data center construction.

[0003] The terminal busbar is characterized by series matching, commercial production, large capacity, short design and construction period, convenient assembly and disassembly, no burning, safe and reliable, and long service life. The terminal busbar product is suitable for three-phase four-wire and three-phase five-wire data center network cabinet power supply projects with AC 50Hz, rated voltage 380V, and rated current usually 250A-400A.

[0004] With the development of information technology, the application of terminal busbars has become more and more extensive. However, although the thickness of the busbar is only 5mm, the length of the busbar is limited. The busbar needs to be connected in sections at a time. Different manufacturers use different structures for the connection points of the busbar copper bar, but they usually occupy a large space, which increases the local size of the busbar (mainly the thickness). In this way, the previous efforts to reduce the installation height of the busbar will be wasted due to the increase in the size of the connection point. In addition, the installation of the busbar usually encounters building columns. The usual practice is to use corner busbars to bypass the column. It usually takes 4 right-angle busbars and three sections of customized short busbars to bypass one column. The disadvantages of this method include: the need for on-site mapping and product customization; too many connections, and therefore more fault points (up to 8).

[0005] As for the connectors of cables and copper busbars, there are no corresponding insulating spacers for different forms of flexible connection components. Summary of the invention
