ABSTRACT:
A protective casing for optical instruments, particularly a weatherproof casing with a casing shell (2), a casing axis A--A, a front wall (3) and a backwall (4) located on each end of the casing shell, and a casing support (9) located on the underside, which is attached to a stationary base (12). With at least one electric cable (23a) leading to a connector plug (11) located on the backwall (4). A detachable cable casing (20) is provided to house the cables out of sight, which extends from the base (12) to the connector plug (11), and together with the wall elements of the protective casing forms a closed cable conduit (21). At least one electrical cable (23a) runs inside the cable casing (20). A particular advantage is that the cable casing first runs between the casing support (9) and the cable casing (20) parallel to the surface of the casing shell (2), forming the first segment (21a) of the cable conduit (21), and then is led in an angle around the back bottom edge (22) of the backwall (4). From there it runs forming the second segment (21b) of the cable conduit (21) to the connector plug (11), overlapping the same.
