ABSTRACT:
A disassemblable gas-tight and pressure-resistant electrical lead-out for battery cells, consisting of a metallic fixed outer sleeve, a metallic bolt effecting the current conduction and of an insulating piece disposed between the sleeve and the bolt that consists of three sleeve-shaped insulating members disposed axially one behind the other and filling out the interstice between bolt and sleeve; the center insulating member consists of a practically gas-tight deformable material while the two outer members consist of a non-deformable material and at least one of the two outer members is adapted to be axially tightened with respect to the center member; the two outer members are provided on their side facing the center member with a ring-shaped raised portion which penetrates into the center member during axial tightening.
