#1. Field of invention

#The present invention relates to an electric connection box and more particularly to an electric connection box arranging a plurality of vertical bus bars in parallel inside a case, in which the vertical bus bars are electrically preferably connected to each other. The present application claims priority to Japanese Application No. 2002-117284 filed Apr. 19, 2002.

#2. Description of Related Art

#FIG. 1 is an exploded perspective view showing a junction block (electric connection box) according to a first embodiment of the present invention;

#FIG. 2 is a perspective view showing vertical bus bars according to the first embodiment of the present invention;

#FIG. 3 is a main parts-enlarged view showing a state in which the vertical bus bars are connected to each other according to the first embodiment of the present invention;

#The embodiments of the present invention will be described below with reference to drawings.

#FIGS. 1 through 4 show a first embodiment. An electric connection box of the first embodiment is a junction block 15 including an upper case 13 accommodating a large number of vertical bus bars 10 and 11 arranged in parallel, and a lower case 14 put on the upper case 13.

#The vertical bus bar consists of two types. As shown in FIG. 2, the long and narrow vertical bus bar 10 has six male terminals 10c projecting from one side thereof. Two pressure-welding pieces 10b each having an approximately L-shaped bent part lob-I and two pressure-welding tabs 10a each having a pressure-welding slot 10a-1 project from the other side of the vertical bus bar 10, with the pressure-welding pieces 10b and the pressure-welding tabs 10a alternating with each other at certain intervals. Lance parts 10d are formed on a side surface of the long and narrow vertical bus bar 10 at its required positions, with the lance parts 10d spaced at certain intervals.
