Branching junction box and method for assembly thereof

摘要

A positioning cylinder to close positioning holes in both the upper and lower casings of a branching junction box so as to prevent dirt and moisture from entering. The positioning cylinder is preferably integral with the upper casing and hollow so as to allow it to fit over a positioning pin employed as a locator during the assembly of the junction box. The positioning cylinder not only closes the holes that are in the upper and lower casing of the junction box, but also stabilizes the busbar substrates that are in the junction box and provides for a more integral and secure junction. <IMAGE>
