Description

The invention relates to a connecting device and a associated connector for use in this connection application device.

The technical development goes that always high frequency tere signals, for example television signals, radio signals, Te Telephone signals, ISDN signals, broadband signals, also in the home area must be transferred and distributed. Doing it there are increasing difficulties with the assembly associated cable and connection systems in the living area. So is in the contacting or distribution of Ka shield the shield for high-frequency signal transmission Coupling electromagnetic radiation respectively Coupling of this radiation is interrupted, causing interference in neighboring devices or transmission lines can. So far, the problem of shielding has been solved sen tries to shield the incoming cable over the socket is connected to the shielding of the outgoing cable has been.

From US-PS 4,990,094 a distribution device for Da known ten transmission, with a conductive panel with public is used to make a connector for a data line device on the back. Shielded data link which are mounted from the back of the panel and are electrically connected to the panel. The electrical connector of which have the form of shielded subunits, according to installation in the panel connected via a contact finger who is stretching away from the panel and thus the Subunit contacted. The panel is for use  determined with patch cables that have end connectors that are detachable can be connected to the panel to make the shielded Connect subunits together. Despite great efforts It is not possible with this connection arrangement shield the individual wires of the data transmission cable. Therefore, these wires can influence each other electrically rivers.

A modular connection arrangement is known from PCT / US 87/01405 known from a circuit board on which the jewei service socket is attached. The circuit board has conductor tracks on the side facing the cable connection, who uses a corner connector to lay the connection with the Make the cable. By replacing the circuit boards you can Various service plugs (Token-Ring, 10 Base-T, 100 Ba se-T and the like) can be connected. The connection level the service connection is perpendicular to the circuit board level. The corner connector consists of a contact unit for connection termination of the cable with so-called barrel contacts and one Row of eight strip contacts for contacting the conductors plate. This means that only eight cores can be con be clocked. This known connection arrangement is inso far unsatisfactory than the individual wire pairs not are shielded, a pre-assembly of individual pairs and the division into several cans is not provided and there with is impossible, and finally carrying out the crowd from the cable connection via the circuit board is not provided.
