Accumulator having a screw terminal

摘要

In the case of an accumulator having a screw terminal with a screw (1) which is screwed into a threaded insert and consists of conductive material, and whose screw head (3) is covered by an insulating layer (4) resting tightly thereon, the protection against being touched and protection against penetrating electrolyte fluid (which corrodes parts of the screw terminal) can be maintained, and a direct voltage measurement can nevertheless be carried out on the terminal, if there is incorporated into the screw head (3) a recess (5) which is filled with a conductive, acid-resistant material (6), and if the insulating layer (4) has a small perforation (7) in the region covering the recess (5). <IMAGE>
