NOVELTY - Connection device (4) for connecting an electrical conductor(s) to an electrical solar module assembly comprises a housing (6) provided with a lower housing region and a housing cover (42). The lower housing region is provided with a base component (34) with a base surface (36) for placing onto a surface of the solar module assembly; and a central component (20) between the base component and the housing cover having a connection port(s) (30) for the introduction of the electrical conductor into an internal space (18) of the housing.    USE - Connection device for connecting an electrical conductor(s) (e.g. of a connecting cable) to an electrical solar module assembly for photovoltaic generation of electrical energy (claimed).    ADVANTAGE - The connection device is comparatively cost-effective to produce. Due to the division of the lower housing region of the housing of the connection device into two components, each of these components is comparatively simple from a manufacturing viewpoint, and can be produced with a simple injection tool. It is possible to create the connection ports located in the central component without the material accumulations in the region between the connection port and the housing base, since better access from two sides is enabled for the creation of the connection ports in the central component. The formation of sink marks in this region can thus also be reduced or even prevented, with the result that any post-injection of melted compound is no longer necessary. The design of a connection device enables a shorter manufacturing process, which is less complex from the manufacturing viewpoint and is more cost-effective. The connection device, specifically its housing, can be assembled in modular fashion. Thus, it is possible to configure the housing variably in the region of the central component to take account of differing requirements relating to the application area of the connection device, and to match the housing of the connection device to different cable diameters of a connecting cable to be introduced. The modular design further makes it possible to adapt an already installed connection device to any subsequent requirements. The central component is exchangeable, and can be replaced by a central component matched to the particular application without having to detach the entire housing unit from the solar module assembly. The connection device can thus be upgraded or modified subsequently. Owing to dual-sided injection, the cable entries and the housing wall can be created with precision and in a material-saving manner from opposing directions. This two-part splitting of the lower housing region renders the housing design simpler to produce, so that the connection device is overall more cost-effective to manufacture.    DETAILED DESCRIPTION - Connection device (4) for connecting an electrical conductor(s) to an electrical solar module assembly comprises a housing (6) for attachment to an electrical solar module assembly and for connection of electrical conductor(s) to the solar module assembly. The housing is provided with a lower housing region and a housing cover (42), and forms a housing internal space (18). The lower housing region is provided with a base component (34) with a base surface (36) for placing onto a surface of the solar module assembly; and a central component (20) between the base component and the housing cover having a connection port(s) (30) for the introduction of the electrical conductor into the internal space of the housing. The central component encloses a portion(s) of the internal space of the housing, and provided with a locking device to join the central component to the base component. An INDEPENDENT CLAIM is included for solar module assembly for the photovoltaic generation of electrical energy.
