ABSTRACT:
An electrical connection box includes an internal circuit in which a several pressing contact terminals are brought into pressing contact with a wire. Input-output terminals of the pressing contact terminals are connected to external circuits. The wire includes an electrically operative portion between one of the pressing contact terminals connected to an external electrical heating element (such as a relay, a fuse, or the like) and another one of the pressing contact terminals. In one example (FIGS. 5 and 6), the electrically operative portion is shifted from a minimal distance path, which takes into account other wires and obstacles, between the one pressing contact terminal and the another pressing contact terminal. This lengthens the wiring path of the wire to a region having a low wiring density which provides additional surface area for heat dissipation. In another examples, (FIGS. 7 and 8) inoperative ends (b, c) of the wire are extend and used to dissipate heat. An inoperative separate wire (W6) can also dissipate heat (FIG. 6). A large contact area (FIGS. 10-18) can dissipate heat and may be formed with splice wires (FIG. 11) and/or a large opening for loosely receiving a wire (FIG. 18).
