Description

Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a through-wall terminal for a simple copper busbar fixing method. Background Technology

[0002] For ordinary through-wall terminals, the copper busbar fixing method on the connector is either cumbersome and complicated, or the fixing is not reliable and is easy to loosen. With the continuous development of new energy, there are more and more through-wall terminals for copper busbar connection. Because the internal high-voltage circuit is usually connected, the safety requirements are very important. To increase the drag adaptability of the copper busbar fastening, conventional copper busbar installation uses screws and nuts at the bottom for fixing or simple snap-fit ​​assembly. Both of these are complicated to install or are prone to fixing failure due to drag force. Moreover, the process is cumbersome and the cost is also high. Utility Model Content
