An electric wiring block composed of a block main body and various cassette blocks. The block main body includes a plurality of cassette receiving chambers which are identical in shape with each other and into which the cassette blocks are received, and, on the respective inner peripheral walls of the cassette receiving chambers, securing ribs are respectively provided. Also, on the outer peripheral wall of the block main body, external securing ribs for option cassettes are provided, while the external securing ribs are identical in shape with the securing ribs. Further, on the outside portions of the cassette blocks, which are identical in shape with each other and are used in common with different kinds of electric parts, lock claws are provided for inserting the cassette blocks into the cassette receiving chambers, and option lock claws are provided for fixing the cassette blocks to the outside portion of the block main body.

Electric wiring block

An electric junction box in which electric power is distributed to electric parts or devices, mounted on an upper side of a part-mounting floor portion of an upper case, through bus bars mounted on a lower side of the part-mounting floor portion. In the electric junction box, a peripheral wall of an upper case has a heat-radiating wall portion which projects upwardly beyond the position of mounting of the electric parts on the part-mounting floor portion of the upper case. The heat-radiating wall portion has a bus bar installation space of a slit-like cross-section which is open to the lower surface of the part-mounting floor portion, and receives the connecting plate of the bus bar.

A waterproof protective cover includes an upper casing member and a lower casing member pivotably connected to the upper casing member through a hinge. When the upper casing member is fitted to the lower casing member, a storage chamber for accommodating a connection part of connected wires is defined by the casing members. The upper and lower casing members are provided on respective interior walls thereof with reinforcement ribs which extend in the longitudinal direction of the casing members and which are positioned between the electrical wires accommodated in the casing members. With the arrangement, it is possible to increase the rigidity of the upper and lower casing members.
