Wall installation connection box unit with an extension sleeve
A wall installation connection box unit, including a box housing body having a rear-side base portion and a sleeve portion projecting forward from the base portion, which sleeve portion peripherally surrounds an installation component mounting space, which space is accessible via an open front end face of the sleeve portion, an extension sleeve which is configured for coaxial arrangement on the sleeve portion and axial pushing back relative to the sleeve portion, and a retaining structure which allows axial pushing back of the extension sleeve on the sleeve portion from a mounting position to an end use position on variable axial level and retains the extension sleeve in the end use position on the sleeve portion. Illustratively, the retaining structure includes a retaining ridge structure radially projecting from the sleeve portion, which is formed integrally with at least one adjacent axial partial region of the sleeve portion from a sealing resilient material, and a counter-retaining structure cooperating with the retaining ridge structure in a frictionally engaged and/or form-locking manner, provided on the extension sleeve and made from a material which has greater stiffness as compared to the sealing resilient material. In addition or as an alternative, the wall installation connection box unit includes a spacer element which is attachable to the box housing body in a securing position in a detachable manner, where the spacer element secures the extension sleeve in the mounting position against axial pushing back.
