Method of manufacturing electrical junction box

摘要

A method of manufacturing an electrical junction box, which is provided with a casing constructing an outline thereof and accommodating a circuit board having a desired circuit pattern, a plurality of housings mounted outside the casing for connecting electrical parts such as a fuse, relay and a connector for wiring harnesses, wherein terminals drawn out from the circuit of the circuit board are accommodated in an aligned form in each of the housings, the method comprising the steps of: making a plurality of terminal insertion holes along a predetermined pattern composed of a plurality of paths formed in the casing; forming a circuit pattern by screen printing an electrically conductive paste on the inner surface of the casing from the upper position of the terminal insertion holes; pressure inserting a bottom base portion of the respective terminals into a corresponding one of the plurality of terminal insertion holes; and forming an electrically conductive circuit pattern by depositing a plated layer of a desired thickness onto the screen printed circuit pattern to which the terminals are pressure inserted.
