  • Patent number: 5923238
    Abstract: An overvoltage protective module comprising a base body made of plastic with embedded contact strips, overvoltage suppressers arranged on the top of the base body and provided with fuse elements, and contact springs which hold the overvoltage suppressers and the fuse elements on the base body and are used to make contact with the contact strips when a fuse element softens in response to an overvoltage. In order to simplify the structure of such an overvoltage protective module, the contact springs (5) are formed on a spring comb (7) which can be clamped onto the top (6) of the base body (1) and whose web (8) which holds the contact springs (5) has at least one spring contact (9) for making contact with a ground conductor (10).
