  • Patent number: 9478955
    Abstract: A feedthrough device (10) for an explosion-proof housing constructed as a “flameproof enclosure” of the flame protection type. The feedthrough device (10) is arranged in a wall opening of the housing and forms a flameproof gap therein. A rigid component (11) is arranged through said gap to be displaced in its direction of extension relative to the wall. The feedthrough device (10) has a clamping body unit (20), a sleeve (21), a cap (22) and a thrust collar (23). The sleeve (21) and the cap (22) can be screwed together. Axial forces are transmitted between the clamping body unit (20) and the cap (22) via the thrust collar (23). The sleeve (21) exerts a radial clamping force on the clamping body unit (20), which is fully penetrated by a conduit (25) along a longitudinal axis (L), in which conduit a longitudinal section of a component (11) is arranged.
