Electrical connector housing

An electrical connector housing comprising a first shell carrying connector mounts, fuse mounts and relay mounts, and a second shell fitted to the first shell, the electrical connector housing containing at least a first bus bar stack formed by a lamination of at least one group of bus bars and layers of insulator material, said electrical connector housing comprising:

• a connector circuitry module being formed of said first bus bar stack and including connector-connecting circuits wired into said connector mounts;
• a fuse circuitry module being formed of a second bus bar stack including a lamination of at least one group of bus bars and layers of insulator material and including fuse-connecting circuits wired into said fuse mounts;
• a relay circuitry module being formed of a third bus bar stack including a lamination of at least one group of bus bars and layers of insulator material and including relay-connecting circuits wired into said relay mounts;
• and
• said connector circuitry module further comprising a flexible printed board containing conductor patterns;
• wherein said first bus bar stack comprises bus bar terminals projecting therefrom and arranged into said fuse mounts and said relay mounts, said first bus bar stack comprising an area where no bus bar terminal is formed, and said flexible printed board is arranged in said area;
• and
• wherein said circuitry modules are arranged in said electrical connector housing in order from top to bottom, a top layer including said first bus bar stack, an intermediate layer including said second bus bar stack and said third bus bar stack next to each other, and a bottom layer including said flexible printed board, so that said first, second, and third bus bar stacks contact said flexible printed board.
