CA 2329984

In the termination of signal cables with two or more wire pairs, it is customary to effect a clamping of the cable in order to relieve the strain on the wires themselves and the terminal connections. This, however, results in an uncontrollable re-arrangement of the wire pairs with associated interference between them. With the invention, this is avoided in that the termination or the strain-relieving element is configured with mutually separated lead-in passages for the individual wire pairs, and with associated clamping means for each of the wire pairs led through the passage. There is hereby achieved a well-controlled electrical separation between the wire pairs, and also an improved mechanical strain relief, i.e. by a primary clamping of the wire pairs themselves. By using a wedge part for insertion into the end of the cable, it can be ensured that the wire pairs extend from the end of the cable in an evenly inclining manner, whereby signal reflections from the area will be minimised.

Il est habituel de pincer l'extrémité des câbles de signalisation à deux paires de fils ou plus pour atténuer les tensions sur les fils eux-mêmes et sur les raccordements des bornes, ce qui produit néanmoins un réarrangement non contrôlé des paires de fils et la possibilité de les confondre. L'invention y remédie en ce sens que l'extrémité ou l'élément atténuant les tensions comportent des passages d'introduction séparés et des pinces séparées pour chacune des paires de fils traversant les passages. On obtient ainsi une séparation électrique nette entre les paires de fils et de plus une meilleure atténuation des tensions mécaniques par exemple en effectuant un pincement préalable des paires de fils elles-mêmes. En introduisant un coin à l'extrémité du câble, on assure que la paire de fils sort de l'extrémité du câble avec une inclinaison régulière ce qui réduit au minimum les réflexions de signaux provenant de la zone.
