Common-box insulated enclosed busbars have emerged as a new type of distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in large current transmission. This method has reliable connection and can avoid interference with the external environment.

[0003] The prior art has the following problems:

[0004] 1. The existing common box insulated enclosed busbar has limited firmness and stability in the connection between adjacent busbars during use, which also leads to the problem that the connection of the busbar is prone to loosening as the use time increases, which indirectly reduces the practicality of the busbar and is inconvenient to promote;

[0005] 2. The existing common box insulated closed busbar has poor sealing performance and is not particularly ideal. This also causes the busbar to be used in an environment with relatively high humidity for a long time. Its connections are easily corroded by moisture, which in turn causes problems such as short circuit or leakage, indirectly increasing the maintenance cost and failing to meet the use requirements. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a common-box insulated enclosed busbar, which solves the problem that the connection between adjacent busbars is limited in firmness and stability during use, which also causes the busbar's connections to become loose as the use time increases, and its own sealing performance is poor and not particularly ideal. This also causes the busbar to be used for a long time in an environment with relatively high humidity, and its connections are easily corroded by moisture, which in turn causes problems such as short circuits or leakage.
