Plug connection device comprising at least one plug connector

A plug connection device for connecting to an electrical cable of the type having an outer conductor and at least one inner conductor and for establishing a ground connection between the outer conductor and a component external to the plug connection device by way of a ground cable which is electrically connectable between the plug connection device and the component, said plug connection device comprising:

• (a) at least one plug connector, each plug connector including
• (i) a plug body which is electrically and mechanically connectable to the outer conductor of the electrical cable, the plug body having an external perimeter;
• (ii) an inner conductor part which is electrically and mechanically connectable to the inner conductor of the electrical cable, and
• (iii) a housing having an outer side which includes a groove, the housing also having a receptacle which receives the plug body in an axial direction;
• said plug connection device further comprising
• (b) fastening means electrically and mechanically connectable to the plug connector for establishing the ground connection by way of the ground cable, the fastening means having a snap-fit connection part, a contact element and a connection element, the snap-fit connection part, the contact element and the connection element being configured integrally with one another, the contact element and the connection element being electrically connected with one another;
• the snap-fit connection part intruding at least partially into the groove of the outer wall of the housing in a form fitting manner to mechanically connect the fastening means to the housing of the plug connector in the axial direction, the contact element having a region which plugs into the housing and makes electrical contact with the external perimeter of the plug body, the connection element being connectable to the ground cable to establish the ground connection independently of the electrical cable, the ground connection being established via the plug body, the contact element, the connection element and the ground cable.
