dubbelkopplingslåda

Dubbelkopplingslåda (double coupling box) is a box or housing intended to enclose two coupling assemblies or junctions, providing a protected and organized enclosure for the connections between two lines. The term is used across several engineering domains. In electrical work it can refer to a double electrical junction box or a terminal enclosure used to connect two cable runs, offering two entries for conductors, terminal blocks, and a mounting point for support. In fluid or pneumatic systems it may house two quick-connect couplings for hoses or pipes, enabling quick disconnects while keeping dust and moisture out.

Typical features include two separate housing sections or a shared compartment with two pass-throughs, knockouts for conduits or hoses, and integrated mounting flanges. Materials range from steel or aluminum to reinforced plastics, with gaskets or seals to achieve weatherproofing (IP-rated) where needed. The box often includes labeling areas and provisions for strain relief.

Usage examples include automotive and industrial equipment where two lines must be joined or controlled, irrigation or water-treatment installations, and machinery that requires a compact, dual-connection point.

Design considerations include ensuring compatibility with the specific type of coupling (electrical terminal blocks, hydraulic or pneumatic fittings), appropriate protection level, allowed fluid or voltage, environmental conditions, and accessibility for maintenance or replacement.
