<p>PROBLEM TO BE SOLVED: To provide an interlayer connection structure which enables various types of branch connections and joints, while the number of types of bus-bars used in a bus-bar layer is not increased. SOLUTION: A branch box employing this interlayer connection structure has bus-bar insulating boards 31 on which a plurality of bus-bars 33 are laid in parallel with each other, and which have a plurality of terminal retaining apertures 43 drilled along one side edge in a longitudinal direction of the bus-bar 33 with predetermined intervals; compression contact terminal elements 35 which are fitted to the terminal retaining apertures 43 in order to be connected electrically to the bus-bars 33; a plurality of wires 39 which are connected by compression to tip compression contact blades of the compression contact terminal elements 35, piercing through the terminal retaining apertures 43; wire retaining insulating boards 37 on which the wires 39 can be wired and fixed; and upper and lower cases 40 and 42 with which the components, are covered.</p> |
