Fuse box for protecting electrical lines in motor vehicle electrical system, has plug-in connector connecting incoming line and outgoing lines with each other and safety fuses designed as polymeric positive temperature coefficient-elements

摘要

The box (1) has a plug-in connector connecting an incoming line (4) and two outgoing lines (5) with each other. Safety fuses are designed as polymeric positive temperature coefficient (PPTC)-elements (6) and are reversible. A busbar is electrically connected with the PPTC-elements by a contact point (7), which is designed as soldering-, welding-, crimping- or adhesive joints. Broad conductive paths (3) are arranged on a printed circuit board (2) and are associated with the outgoing lines. The PPTC-elements are connected with the conductive paths.
