Abstract

PURPOSE:To increase the resistance force against the tensile force of a joint section by inserting pin-shaped projections of a protective plate into many hooking small holes provided on the joint section of a flexible flat cable. CONSTITUTION:Flexible flat cables 1 and 2 with many foil-shaped lead wires 1a and 2a have joint sections 3 welded together at end sections by ultrasonic waves. Many through holes 8 penetrating insulating sections between foil-shaped lead wires and many pin-shaped projections 7 penetrating the through holes 8 are provided near the joint section 3. The joint section 3 and its vicinity are pinched by protective plates 5 and 6, projections 7 of the protective plate 5 are inserted into through holes 8 of the protective plate 6, and projections 7 of the protective plate 6 are inserted into through holes 8 of the protective plate 5. Multiple (up to eight) flat cables F1, F2,... with joint sections 3 are stacked with joint sections 3 staggered in sequence between protective plates 5 and 6, then projections 7 of protective plates 5 and 8 are inserted into through holes 8 together, and they are melted and solidified to fasten the upper and lower protective plates 5 and 6.

For example, in automotive wiring harnesses, the joints are wrapped with tape, or when the number of wires is increased, the joints become thicker, which impairs the flatness that is an advantage of flexible flat cables. In addition, in order to connect the foil conductors of flexible flat cables, conventionally the terminals are connected to the foil conductors by crimping, soldering, etc., but in either case, the thickness of the joint part increases. This creates the problem of

[Problems to be Solved by the Invention] Therefore, in order to maintain the advantage of the thinness of the flexible flat cable, it is desirable to join the foil conductors together by ultrasonic welding. However, since ultrasonic welding uses ultrasonic waves to weld conductors together, they are not completely joined like soldering, and the problem is that the welded conductors tend to separate when tensile force is applied. There is.

In the above example, the upper and lower protection plates 5 and 6 that sandwich the flat cable are the same part, but as shown in FIG.
By providing the through hole 8 through which the pin-shaped protrusion 7 passes only in the protection plate 5 on the other side, the workability of assembly can be improved. In any case, the number of pin-like protrusions 7 is the same as that of the flat cables Fl, F2. It can be reduced appropriately by changing the number of F3, . . . , etc., and it can be fixed by arranging the four corners of the protection plates at the minimum. Alternatively, the upper and lower pairs of protection plates 5 and 6 may be joined at the hinge portion and molded into one piece, folded at the hinge portion, and then sandwiched between several flat cables F. good.
