Patent ID: 8033408

Claim:
An apparatus comprising an enclosure which has a lead-through for passing a rod-like element through a wall of the enclosure, said lead-through being formed in a boundary surface between a base section and a lid section of the enclosure, such that either the base section or the lid section is formed with a cutout, which opens from the boundary surface into the enclosure wall and which has a rim starting from a first point of the cutout rim present at the boundary surface and extending to a second point of the cutout rim present at the boundary surface; and, a grommet comprising a passage for passing the rod-like element, the grommet configured to set loosely in place in the cutout, a side of the grommet corresponding to the boundary surface lies at a distance outside the boundary surface, the grommet having one split face, which establishes an openable route between the exterior of the grommet and the passage, the grommet having a first recess transverse to an axial direction of the passage for the rod-like element, and a second recess, the first recess being configured to match the cutout rim and the second recess being configured to receive a clamping element which is configured to secure and seal the rod-like element to the grommet by applying a radial compression to the rod-like element; wherein the enclosure is configured so that when the enclosure has its lid section sealingly attached to the enclosure's base section, an engagement force therebetween causes the side of the grommet corresponding to the boundary surface to press itself flush with the boundary surface, the grommet clamping and sealing against the rod-like element, against the rims of the cutout to the wall and against the side of the grommet corresponding to the boundary surface, and further wherein sealing elements in a split face of the grommet clamp and seal against each other.
