The invention relates to a multiple signal cable system having a plurality of individual plug heads formed at the free ends of the cables for connection to a corresponding number of counter-piece contacts on a unitary adapter. The present invention permits a simplified manipulation of the multiple plug heads for connection with the adapter, while also affording rearrangement of the sequence of individual plug heads in accordance with the particular adapter. The individual plug heads are connected together in a consolidated, unitary arrangement by means of a housing collar having a sequence of side-by-side chambers for respectively securing the plug heads tightly therein. Lock means are provided on the housing and plug heads to secure the plug heads against relative movement and prevent the individual plug heads from falling out or being withdrawn from the unitary arrangement; however, the lock means are releasable to permit removal or rearrangement of the plug heads as needed.

In an exemplary embodiment, a device housing with a signal processing part, includes at least one recess into which at least one insert with a cladding of insulation material of high electric strength can be inserted as a signal transmission part, whereby both the recess wall and the insert are carriers of mutually cooperating primary and secondary coupling elements of a galvanically separating coupling location for energy and signal transmission, the coupling elements, however, only combining to form the coupling location when the insert is inserted into the recess. The object of the disclosure is to create such a device which allows of combinations consisting of the recess and the insert which are dimensioned to provide as large a volume or as large a surface area as desired without having a leakage current which may be possibly flowing assuming an inadmissibly high value as a result. This object is achieved in that the recess in the device housing is lined with an insulating body likewise of insulating material of high electric strength or that such an insulating body itself forms the recess, with the insulating body finally accepting the insert in its interior space.

A plug contact assembly, comprising a female plug member and a corresponding male plug piece, is provided with an interlocking means utilizing a locking tongue member which is protected from deformation and mechanical stress within the confines of an annular surrounding socket wall. The tongue is a free-extending, resilient member having at least one detent hump formed thereon and arranged to engage into an associated detent recess formed along a generally flat base wall surface of the other plug section to establish a locking interconnection of the plug contact members. The tongue is spaced beneath an adjacent edge of a plug head portion to define therebetween a groove into which the base wall of the other associated plug section slides during interengagement of the plug members. The groove and base wall are of approximately equal heights such that a tight-fit passage of the base wall into the groove is afforded, thereby assuring proper alignment of connector pins and plug contact holes during the joining together of the male and female plug members.

A recorder such as a pen line recorder is disclosed having a housing with a hinged front which forms a foldout recording table giving access to the interior, the recording table consists of two rectangular plate members one of which is hinged to the housing adjacent a bottom thereof and the other one of which projects upwardly into the housing securing the front in place. The two rectangular members are received in side guide members and are slidable in the guide members with respect to one another whereby one of the members may be moved first downwardly with respect to the other member to provide clearance at the top of the housing and then both members may be pivoted outwardly.
