Abstract
A surge arrester mounting unit is provided for telecommunications and data systems technology. The arrester includes an upper part and lower part made of plastic, and metallic contact elements which are arranged in pairs and which engage, by means of spring arms, in chambers of the upper part in order to made contact with surge arresters. The contact elements have contact blades which project out of the lower part. In order to enable the surge arrester mounting unit also to be used for terminal blocks with high transmission rates, the invention provides for the contact blades (11) for separating contact fingers (directed into the interior of a terminal block) (1)), from insulation piercing contact elements (4) to be made approximately twice as long as the spring arms (19) and to be given more than double the material thickness (d) at the free end by bending over.
