  • Patent number: 6354866
    Abstract: Connecting members 28F and 28R pierce conductors 11 in a state whereby plate faces of these connecting members 28F and 28R are approximately at a right angle with respect to the length-wise direction of the conductors 11. Consequently, if a pulling force is exerted on flat cables 10A and 10B along the length-wise direction of the conductors 11, the connecting members 28F and 28R will not cause edges of slit-shaped piercing locations 35 to split. The piercing locations 35 of the connecting members 28F and 28R (locations where the rigidity has decreased due to their having been pierced) are provided along the length-wise direction of the conductors 11 in a location that is clamped between the connecting members 28F and 28R and a base 22 (the rigidity of these locations does not decrease due to piercing). As a result, if a bending force is exerted on the flat cables 10A and 10B this bending force is absorbed at the clamping locations, and does not reach the piercing locations 35.
