<p>PURPOSE:To prevent insulating boards from becoming bulky in the case of laminating and stocking them when an electric connection box is assembled, to stabilize and to improve operability in the insulating board for a bus bar circuit board in the box to be used for mutual connection, etc., of a wire harness. CONSTITUTION:Insulating boards 611, 612 of bus bar circuit board are provided on one or both side surfaces with ribs 8a for partitioning bus bar arranging grooves 8, and with a structure in which a plurality of fusion-bonding bosses 21 protrude at suitable positions of the ribs and bus bars 4 arranged in the grooves 8 are secured by melting and solidifying the bosses. The bosses 21 are positioned to protrude in a zigzag manner on both front and rear surfaces. Thus, high bulk is avoided, and stability is obtained. It is desirable to provide a plurality of dummy bosses 22, 22',... for protecting the bosses on the insulating board at the time of multiple laminating.</p> |
