Pull-through for transmission element e.g. optical fibre in conduit - using flowing medium and stopper consisting of hard material with soft sealing plug behind

摘要

The o.d of the sealing stopper, made of soft elastic material in a relieved condition, corresponds approximately to the i.d. of the conduit (RO). The elasticity of the sealing stopper (DS) is chosen so that, from the flowing medium (SM), a thickening of the sealing stopper (DS) can be attained. - The linear extended element(LE) e.g. a light conductor, is fixed to the passage stopper. The latter (DS) has an opening through which the transmission element (DS) is passed. The contour of the passage stopper (DZ) is rounded off at its forward end. The passage stopper has an approximately spherical cross-section,. pref hemi spherical.
