ELECTRICAL CONNECTION BOX

PROBLEM TO BE SOLVED: To obtain a high-density electrical connection box for controlling conduction/interruption of electronic autoparts. SOLUTION: The electrical connection box 10 comprises a circuit structure 11 where substrate side bus bars 29 are arranged on a circuit board 28, a lower case 13 for housing the circuit structure 11, an upper case 14 constituting a casing 12, in combination with the lower case 13, a plurality of case side bus bars 42 secured to the inner surface of the upper case 14 by means of a pin 47 provided to the upper case 14 and a bus bar retaining portion 48 provided at the distal end of the pin 47. Since the case-side bus bars 42 can be arranged on the inner surface of the upper case 14, the case-side bus bars 42 can be extended in the electrical connection box 10, without extending the substrate side bus bars 29. Consequently, a higher density electrical connection box 10 can be obtained. COPYRIGHT: (C)2007,JPO&INPIT
