BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a method for producing a connection of data transmission lines and to a plug connector, in particular for use in such a method.
2. Summary of the Prior Art
Fluctuations in the production methods mean that two conductors in a line are never completely identical. When such lines are used for data transmission in the microwave range, these fluctuations lead to so-called propagation delays between the signals on individual conductors of a line. The higher the frequency and the higher the data rate, the greater is the risk of interference due to erroneous data transmission.
U.S. Pat. No. 5,470,244 specifies an arrangement and a method for preventing interference due to crosstalk. For this purpose, individual conductor tracks are interrupted within a multi-pole electrical plug connector and the interrupted connections are rearranged in a second position, which is arranged above the first conductor tracks. Capacitive and inductive coupling are achieved by superposition and by parallel routing of specific conductor pairs.
Taking this prior art as a departure point, the object of the invention is to specify a connection method for data transmission lines and a plug connector, in particular for carrying out this method, with which propagation delay differences can be reduced.
SUMMARY OF THE INVENTION
As regards the method, this object is achieved by means of a method having the features of Patent claim 1. Preferred developments emerge from subclaims 2 and 3.
It is advantageous that the propagation delay difference between two conductors can be reduced in small steps. This is achieved by virtue of the fact that during the method of producing a connection of plug connector and data transmission line, the propagation delay difference between the conductors is measured and it is possible to remove or sever individual conductor sections from the conductive structure in the plug connector, which leads to an altered propagation delay in the plug connector.
As regards the arrangement, the object is achieved by means of an arrangement having the features of Patent claim 4. Preferred developments emerge from Subclaims 5 to 10.
It is advantageous that the plug connector can be used together with different data transmission lines having various propagation delay errors. This is achieved by virtue of the fact that each conductor in the plug connector is connected to a plug transfer contact, by means of an essentially identical conductive structure, comprising identical conductor sections. This conductive structure can then be processed in such a way that it is possible to compensate for various propagation delay differences.
It is furthermore advantageous that the plug connector is simple to produce. This is achieved by virtue of the fact that both the conductor connection contacts and the plug transfer contacts as well as the conductive structure can be produced from a single stamping. This is also achieved by virtue of the fact that the conductive structure is arranged on a printed circuit board or is produced from a metallized plastic substrate.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a perspective illustration of a plug connector which is cut open in the longitudinal axis parallel to the plane of the conductive structures, before the data transmission line has been connected to the plug connector and before the propagation delay difference between conductors has been compensated for; and
FIG. 2 shows a perspective illustration of the same plug connector after the data transmission line has been connected to the plug connector and after the propagation delay difference between the conductors has been compensated for.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The plug connector 1 comprises a housing 2 with a conductor connection side 3 and a plug transfer side 5. The housing 2 comprises a cover part 7 and a base part 9 matching the latter. On the conductor connection side 3, the housing 2 has two conductor connection contacts
