Abstract
For an explosion-proof connection of two electric line ends (), the contact elements () are accommodated in two tubes (), which can be joined in an explosion-proof manner. Each of the plug-in contact parts is axially secured in its tube by a radial projection () in the direction toward the end facing the other tube. At its line end, each of the tubes is closed by an end cap (), which sealingly surrounds with a narrow outlet () the electric lines, including an insulation (). The tube, in which the plug-in contact part with the contact pins is axially secured, extends beyond the tip of the contact pins, and has there an enlarged diameter, with which it surrounds the other tube (inner tube) with a narrow cylindrical gap (sealing gap).
