Coupling device

摘要

A coupling device for connecting a first coupling housing (12) and a second coupling housing (20) is provided. The first coupling housing (12) comprises a guiding element (101; 201; 301a-e; 401b,c; 501b-d) extending from the first coupling housing (12) and having a free end (102; 202; P) at a distance (h) from the first coupling housing central axis (a-a). The second coupling housing (20) comprises a receptacle (123; 223; 323; 423; 523) for the guiding element and pull-in means (8) for pulling the guiding element into the receptacle, said pull-in means (8) being connected to the guiding element free end (102; 202; P). The invention allows the first coupling housing to be pulled towards the receptacle at an angle which is not coincident with the central axis (a-a), and when the guiding element is in place inside the receptacle, the first coupling housing central axis (a-a) and the central axis (b-b) of the second coupling housing are aligned and coincident, and the two housings are rotationally aligned.
