Patent ID: 8109781

Claim:
A set comprising a connection adapter ( 1 ) and connection terminal ( 2 ), with the connection adapter ( 1 ) having electrical contacts ( 7 ) for connection to a corresponding mating contact of the connection terminal ( 2 ), the mating contacts each being accommodated in a connection terminal dome ( 16 ), which is formed from insulating material, such that the mating contacts are accessible to a contact ( 7 ) of the connection adapter ( 1 ) through a respective contact guide opening ( 22 ) in the associated connection terminal dome ( 16 ), and with the connection terminal domes ( 16 ) having connection adapter guides which are designed to cooperate with corresponding connection terminal guides on the connection adapter ( 1 ) for guiding the connection adapter ( 1 ) from a mounting position, in which the connection adapter ( 1 ) is mounted on the connection terminal ( 2 ) in a matching manner and from which the connection adapter ( 1 ) and connection terminal ( 2 ) can be plug-connected, to a latching position, in which the connection adapter ( 1 ) is seated and held on the connection terminal ( 2 ) such that the electrical contacts ( 7 ) of the connection adapter ( 1 ) and the corresponding mating contacts of the connection terminal ( 2 ) can be moved relative to one another in order to make electrical contact, characterized in that the connection adapter guides and connection terminal guides are also matched to one another such that a coding is provided as a function of the provided connection assignment of the contacts present in the connection adapter ( 1 ) and the connection terminal ( 2 ) for making mutual contact, said coding permitting a connection adapter ( 1 ) to be guided on a connection terminal ( 2 ), or vice versa, only given a corresponding connection assignment.
