Cable connection units and protection devices

摘要

A cable connection unit comprises a pile of insulating plates carrying preformed conducting strips. A first end of each strip is connected to or forms a lead-in or lead-out terminal, and a second end is bent in an orifice traversing the pile. Plug modules plugged in one face of the pile have lead-in and lead-out pins contacting the bent second ends of the strips and a grounding pin contacting a grounding grid placed on the opposite face of the pile. The modules have fuses connecting their lead-in and lead-out pins and lightning protectors between these pins and the grounding pins. When a module is not plugged in, the bent second end of the corresponding lead-in terminal comes to contact the grounding grid.
