NOVELTY - The device (1) has a contact rail (100) arranged in a housing (2), and a contacting device (200) for contacting an electrical conductor and fitted to the contact rail and moved between an initial position and an end position. The contacting device is designed such that a contacting space is formed between an inner peripheral face of the contacting device and the contact rail. The contacting device comprises an upper wall and made of a sheet metal material. A clamping unit protrudes from the upper wall into the contacting space and comprises a tool engagement portion.    USE - Electrical connection device i.e. solar box, for electrically connecting an electrical conductor e.g. foil, flat conductor or strip, of a photovoltaic solar module, which is utilized for converting radiation energy directly into electrical energy, to a connection cable. Can also be used for a solar panel.    ADVANTAGE - The contact rail is arranged in the housing, and the contacting device contacts the electrical conductor and fitted to the contact rail and moved between the initial position and the end position, thus reducing structural height of the contacting device, enabling compact construction of the contacting device and consequently optimal use of the inner space of the connection device. The device enables manufacturing the contacting device in a simple manner and ensuring reliable contacting of the foil conductor. The device achieves reliable and cost-effective assembly of the contacting device on the contact rail. The contacting device is made of the sheet metal material, thus ensuring cost-effective and simple production of the contacting device.    DETAILED DESCRIPTION - The contact rail is designed as a conductor rail i.e. punched grid.    DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of a connection device.
