Definitions

  • the invention relates to a terminal board, as it is used as an intermediate part when connecting windings of an electric motor to a power supply device.

It is already not easy to attach two cable lugs to a bolt. However, there is often the additional requirement that the lines, both the in-line and out-side lines, should be split. This is particularly necessary when the electric motor requires relatively high currents. To reduce the resistance then the cable cross-section must be increased, preferably a two-piece cable is used. In the case of split cables, two cable lugs each have to be attached to the connection pole both on the inside connection side and on the outside connection side, in total four.

Abstract

Contrairement à l'état antérieur de la technique, le bornier selon l'invention n'est plus composé de deux rangées de boulons métalliques (14), mais les pôles de connexion sont disposés sous forme de rangées. Des cosses de câbles (16, 18) sont fixées aux pôles de connexion. Pour permettre la fixation de deux cosses de câbles respectives (16, 18), il est prévu, côté connexion extérieure et côté connexion intérieure, que chaque pôle de connexion comporte deux dispositifs de fixation (32, 34) mécaniquement indépendants l'un de l'autre. Ces dispositifs de connexion peuvent se présenter sous la forme de perçages dans une pièce métallique en forme de L (30), orientés dans la même direction, dans lesquels des boulons filetés s'encastrent (40, 42). Le bornier selon l'invention est conçu pour être employé dans divers circuits (44, 44', 44'').
