Abstract
A sealed through-connector in which an electrical connection passes through a hole (4) in a single or double wall made of a plastic material, said connector including a first annular seal ring which seals the annular zone of the orifice left free by the connection and being compressed axially. According to the invention, the connector is axially compressed by clamping means which are applied on either side of the wall (1) to two metal parts (9,10) which each have a surface substantially parallel to said wall (1), the distance between said surfaces and therefore the compression of the seal (8) being defined by the insertion of a metal distance member (5). Use: Storage batteries which use hard metal connection parts which melt at high temperatures, e.g. alkaline electrolyte storage batteries.
