Patent ID: 7387516

Claim:
An electric junction box in which at least three circuit components consisting of first, second and third circuit components are accommodated in a casing with said first, second and third circuit components vertically spaced at certain intervals, and a relay connector is mounted on said second circuit component disposed at a position intermediate between said first and third circuit components; a housing of said relay connector is stepped in a vertical direction thereof and has a part in which vertically long first terminal-accommodating portions are formed and a part in which vertically short second terminal-accommodating portions are formed; each of said first terminal-accommodating portions accommodates a long first relay terminal, and each of said second terminal-accommodating portions accommodates a short second relay terminal; a terminal conductive with an electric conductor of said first circuit component and a terminal conductive with an electric conductor of said third circuit component are inserted from above and below into said first relay terminal to connect said terminals of said first and third circuit component with each other through said first relay terminal; and said second relay terminal is connected with an electric conductor of said second circuit component, and a terminal conductive with an electric conductor of said first circuit component or with an electric conductor of said third circuit component is inserted into said second relay terminal to connect an electric conductor of said first circuit component or an electric conductor of said third circuit component with said electric conductor of said second circuit component through said second relay terminal.
