Abstract
The invention relates to a protective plug (1) for connector banks (20) of telecommunication and data systems, comprising a housing (2) for receiving protective elements (7, 8, 9) connected to establish an electrical connection to an earth rail (44) and with a disconnector contact (43) to a bifurcated contact (41) or to circuit tracks (10) provided on a plug tongue, resp. The disconnector contact (43) is provided with terminal contacts (53) for incoming and outgoing cable conductors. In order to provide a protective plug (1) which protects against overvoltages and serves as well as a fuse against overcurrents and for which the outside dimensions allow a close-fit construction of several protective plugs (1), the plug tongue (5) is a printed-circuit board (4, 4a) extending into the housing (2). Two housing compartments (21, 22) are formed inside the housing (2). Inside the housing compartments (21,22) on either side of the printed-circuit board (4, 4a), protective elements (7, 8, 9 ) are disposed, which are connected to one another over the circuit tracks (10) and over through-plated terminal positions (A to F).
