e' FOR OFFICE USE: Class Int Class Complete Specification Lodged: Accepted: Published: S Priority: S Related Art: Name and Address of Applicant: Siemens Aktiengesellschaft Wittelsba'herplatz 2 0-8000 Munich 2 FEDERAL REPUBLIC OF GERMANY Spruson Ferguson, Patent Attorneys Level 33 St Martins Tower, 31 Market Street Sydney, New South Wales, 2000, Australia t c Address for Service: Complete Specification for the invention entitled: Apparatus for Testing Electrical Conductors in Distribution Frames of Telecommunications Systems The following statement is a full description of this best method of performing it known to me/us invention, including the 5845/4 IA ISOLATING PLUG FOR TESTING ELECTRICAL CONDUCTORS IN DISTRIBUTION FRAMES OF TELECOMMUNICATIONS SYSTEMS The invention relates to a plug for testing electrical conductors in distribution frames of telecommunications systems, in particular telephone systems.
It is known from DE-PS 20 48 104 to make a distribution frame from flat disc-like laminar components which are provided with rows of pairs of opposed connecting elements for the electrical conductors. Each pair of the connecting elements extend virtually rectilinearly from the front of the distribution frame into the interior of the disc-like component where they form opposed contact points for connecting the external and internal conductors of the distribution frame. The contact points can be o0OOo sectionally switched by means of simple isolating plug-in tongues which can o° be inserted from the front of the disc-like component through special 0 plug-in channels between the opposed connecting elements of the pairs.
It is furthermore known in the case of newly opening, extending or exchanging modern for old, communications systems, for the distribution frames to be completely prewired and, until the installations are finally completed, for the conductors to be isolated by means of isolating plug-in 23 devices which extend over the entire width of a disc-like component. Such a multiple plug is shown, for example, in the Siemens Catalogue "Schwachstromverteilereinrichtungen in lotfreier Anschlusstechnik"/"Weak current distributor equipment featuring solder-free connection technology", c state of the art March 1981, page 50. Since the isolating plugs are 2S inserted into all newly fitted disc-like components, they prevent free access to the outer zones of the connection elements for testing purposes.
Such conductor tests must be carried out before the installation is switched on. Testing is performed by means of test leads which have tips shaped to correspond to the pairs of opposed connecting elements. Fitting of the test leads is particularly difficult when the disc-like components are in an elevated position.
The invention is concerned with the problems of facilitating the testing operations.
According to the invention there is provided an isolating plug for testing electrical conductors in a distribution frame of a IAD/10290 ~iiU1-r

clear of the connecting elements of the -la4nark component and are thus readily accessible. The isolating plug can have its outer edge portion so constructed that the connecting tips of the test leads can be fitted easily and securely. The test leads can, for example, be provided with plug-in contacts which are pushed on to the contact zones of the isolating plug.
In a possible further development, the isolating plug is constructed as a printed circuit board. This enables favourably-priced manufacture of the isolating plug. The contact surfaces and contact zones, like the conductor paths, can be produced in one operation.
In a yet further possible development, the isolating plug is constructed as a double-sided printed circuit board. Thus it is possible to test conductors leading from the distribution frame both outwardly and inwardly without the position of the isolating plug having to be changed.
Embodiments of this invention will now be .described, by way of example, with reference to the accompanying drawing in which the sole figure is a perspe:tive schematic view of a component of a distribution frame embodying this invention.
Referring to the drawing, there are shown two opposed rows A'"S C k KffO of connecting elements 1 of a 4lainaE rcomponent (not shown in greater detail) of a distribution frame in a telephone communications installation provided with an isolating plug 2. Also shown are clip-on contacts 3 of test leads which can be attached as required for testing to the plug 2.

Ah -4- One row of the connecting elements 1 serves for connection of internal conductors 4 and the other for connection of external conductors 4. The connecting elements 1 extend from the connection points for the conductors 4 in straight lines into the interior of the La.na I component and form at their inner ends opposed contact points 5 which are separated by interposed plug-in tongues 6 of the isolating plug 2. The plug-in tongues 6 have in the region of the contact points 5 contact surfaces 7 which are contacted by the contact points 5. Extending from the contact surfaces 7 are printed 1O conductor paths 8 which lead to an outer edge portion of the isolating plug 2, where they terminate in contact zones 9 for the clip-on contacts 3. The contact zones 9 lie beyond and clear of the free ends of the connecting elements 1 and are thus readily accessible for the fitting of the test leads. The isolating plug 2 is constructed as a printed circuit board printed on both sides (double-sided printed circuit board) so that both the inwardly and outwardly extending conductors 4 can be tested at the same time.
