Abstract
Bus bars 16(A to D) and 17(A to C) on the two faces of an insulating plate 15 can be electrically connected by arranging the longitudinal bus bars 17(A to C) on one face of the insulating plate 15 and the transverse bus bars 16(A to D) on the other face of the insulating plate 15, by fitting recesses 16a to 16d of the bus bars 16(A to D) of at least the one face at the suitable positions of the intersecting portions of the bus bars 16(A to D) and 17(A to C) of the two faces in through holes 15a of the insulating plate 15 to bring the recesses 16a to 16d into contact with the bus bars 17(A to C) of the face, as confronted thereby, and to weld them 16a to 16d to the same bus bars 17(A to C).
Claims5
A connection structure for bus bars to be housed in an electric connection box comprising:
- longitudinal bus bars which are extended straight in a longitudinal direction at a predetermined pitch on a first face of an insulating plate;
- transverse bus bars which are extended straight in a transverse direction at a predetermined pitch on a second face of said insulating plate;
- wherein
- said insulating plate has through boles at a first predetermined location at intersecting portions of said bus bars on the first and second faces;
- at least one of said bus bars on the first and second faces is provided with at least one preformed recessed portion at a second predetermined location corresponding to the first predetermined location of the through holes so that the recessed portion can be fitted in the through holes;
- and
- the at least one preformed recess is brought into contact with and welded at the through holes so that said bus bars on the first and second faces are electrically connected.

- longitudinal bus bars which are extended straight in a longitudinal direction at a predetermined pitch on a first face of an insulating plate;
- transverse bus bars which are extended straight in a transverse direction at a predetermined pitch on a second face of said insulating plate;
- wherein
- said insulating plate has through holes at intersecting portions of said bus bars on the first and second faces;
- said bus bars for the first face are provided with lower layer compression blades which are extended through slits formed in said insulating plate to the second face of said insulating plate,
- on the second face of said insulating plate, said bus bars are provided at two ends thereof with upper layer compression blades confronting the lower layer compression blades and connector tab terminals, and
- jumper electric wires are compressed on the upper layer compression blades and the lower layer compression blades to connect said bus bars on the two faces electrically.
