Abstract: A connector assembly comprising a female and a male connector part. At least one coding element is attached to each connector part. The coding element provides for a code face having at least one recess. The code faces of the male and female connector parts allocated to each other are complementary in shape. When connector parts allocated to each other are plugged into each other the faces of the respective coding elements engage with each other. Only a limited number of all possible code face shapes are used so that unambiguous code face sets are obtained.

Abstract: A connector having means for securing the connector to a substrate. The securing means comprises at least one metal member which is accommodated in at least one of the walls of the housing of the connector. The metal member has a part projecting at right angles to a plane of the connector wall facing the substrate. The projecting part engages in a corresponding aperture of the substrate where the connector is secured to the substrate by, for example, soldering.

Abstract: A connector for contacting one or a plurality of parallel connectors and retaining the conductors at the contact position. The connector includes two parallel extending contacts between which the conductor is inserted and electrically contacted. The connector further includes rotatable retaining means which enables the conductor to be inserted between the contacts and which also secures the conductor in place after it is contacted.
