The connection device has contact springs, which form input terminals of the connection device, and via insulation displacement contacts, preferably designed as IDC contacts, which form output connections of the connection device. If a data plug is inserted with its plug contacts into the data socket, the plug contacts of the data plug contact the contact springs of the connection device and thus the input terminals thereof. Data conductors of the data cable can be contacted with the insulation displacement contacts of the connection device and thus with the output connections thereof.

A data socket is at a defined data transfer rate of z. B. 10 Gbit / s at a defined fundamental frequency component of z. B. 500 MHz and must meet in this context specific technical requirements, for example, to a so-called near-end crosstalk, a so-called far-end crosstalk and a so-called return loss. To verify that data sockets meet the specific technical requirements, the data sockets must be subjected to tests or tests.

If a data socket according to the prior art to be subjected to a test or test, so far the output terminals of a data socket must be consuming connected with cables of defined length and the cables with electrical resistors to perform the tests. This has been done manually so far, making it difficult to provide reproducible results from such tests. Therefore, there is a need for a data socket test terminal device that allows the output terminals of the data socket to be easily and safely terminated to perform a test while ensuring reproducible results.

In order to prepare a test or a test using the test connection device according to the invention, the output connections of a data socket to be tested or tested only have to be plugged into the plug contacts of a first circuit board of the test connection device according to the invention. The assemblies required for carrying out a defined test are integrated on the printed circuit boards of the test connection device according to the invention, so that a test can be carried out after merely plugging together the data socket and the test connection device according to the invention.

This not only simplifies the performance of tests, but also reproducible results of such tests can be provided.

Preferably, the Prüfanschlussvorrichtung comprises two opposing first circuit boards, each first circuit board having two approximately parallel rows of a plurality of plug contacts for electrically contacting the output terminals of a data socket, with each first circuit board two second circuit boards cooperate, which carry the electrical resistors, which are connected via the conductor tracks with the plug contacts of the first circuit boards, and wherein the first circuit boards and arranged perpendicular to the respective first circuit board second circuit boards each side faces of a Parellelelepipeds, in particular a cuboid form.

It is then sufficient that the three circuit boards 11 . 12 and 13 , which form three side surfaces or side walls of a cuboid or cube, are designed as printed circuit boards.

The other side surfaces or side walls of the cuboid or cube, which in 1 to 4 are not provided with reference numerals, can also be designed as printed circuit boards, but must in the embodiments of the 1 to 4 not be designed as printed circuit boards, since they only the mechanical stabilization of the three-dimensionally arranged printed circuit boards 11 . 12 and 13 serve.
