1. A head part of an implantable medical device, comprising:
a housing which has at least one first blind hole plug contact socket including a socket opening and a socket base axially opposite the socket opening, along which extends at least one electrically conductive contact ring and an electrically insulating, elastically deformable sealing ring which are enclosed by a solidified casting compound and are joined together coaxially in a sequence;
at least one second blind hole plug contact socket within the head part including a socket opening and a socket base axially opposite the socket opening between which at least one electrically conductive contact ring element and an electrically insulating elastically deformable sealing ring are located which are enclosed by the solidified casting compound to be joined together coaxially in a serial sequence;
the socket bases of the at least two plug contact sockets each being delimited by a connection at least partially enclosed by the solidified casting compound; and
the connection includes a through channel which on both sides of the channel opens out into the blind hole plug contact sockets.
