【Example】

 The terminal processing component 10 of the embodiment shown in FIGS. 1 to 3 is a molded product of a heat-resistant insulating material such as plastic, for example, and a receiving portion for receiving an end portion 14 of a flat flexible cable 12 inserted from one end side. 16 and extending from the receiving portion 16 to the other end, hollow grooves 20 are formed parallel to each other. The hollow grooves 20 each receive a respective conductor 18 exposed at the end 14 of the flat flexible cable 12. The conductor 18 inserted into each hollow groove 20 is connected to an external circuit (not shown) by soldering at a soldering window 22 formed above the hollow groove 20.

More specifically, each conductor 18 of the flat flexible cable 12 is covered with an outer cover made of an insulating material such as polyester, and in this embodiment, each conductor 18 extends from the end 14 of the flat flexible cable 12 to the conductor. It has been processed in advance so that 18 is exposed. As can be clearly understood from FIG. 2, the receiving portion 16 has an inner shape that matches the outer shape of the end portion (outer sheath) 14 of the flat flexible cable 12, and the end portion 14 is pressed into the receiving portion 16. The hollow groove 20 is formed to extend from the receiving portion 16 to the other end of the terminal processing component 10, and each inner surface shape matches the outer surface shape of each conductor 18. In this embodiment, the length of the conductor 18 exposed from the end 14 of the flat flexible cable 12 is equal to or slightly shorter than the length of the hollow groove 20. By inserting the conductor 18 into the hollow groove 20 and the end portion 14 into the receiving portion 16, the terminal treatment component 10 is fixedly attached to the end of the flat flexible cable 12.

In addition, on the upper surface of the terminal processing component 10, as shown in FIGS. 1 and 2, a soldering window 22 is formed on each hollow groove 20. Through the soldering window 22, the conductor 18 is soldered to an external circuit (not shown). The soldering windows 22 are provided so as to be shifted from each other in the longitudinal direction of the hollow groove 20 so that a short circuit between the adjacent conductors 18 does not occur during the soldering connection. Also, if a portion of the conductor 18 that is exposed from the soldering window 22 is subjected to a pre-processing such as a flux coat or a solder coat, the soldering is easy.

In the embodiment shown in FIGS. 4 and 5, mounting pieces 24a and 24b are formed to protrude outward on both sides of the terminal processing component 10 similar to the embodiment shown in FIGS. Through holes 26a and 26b are formed in 24a and 24b, respectively. Further, pins 28a and 28b extending downward from the lower surface of the component 10 are formed corresponding to the positions of the mounting pieces 24a and 24b. The pins 28a and 28b are inserted into holes (not shown) formed in a mounting portion of, for example, a board, a chassis, or a case, and tightened with screws (not shown) through the through holes 26a and 26b. The terminal processing component 10, that is, the end portion 14 of the flat flexible cable 12 can be fixedly attached to the attachment portion.

In the embodiment shown in FIGS. 1 to 3, the conductor 18 and the end portion 14 of the flat flexible cable 12 are sequentially pushed into the hollow groove 20 and the receiving portion 16, so that the terminal processing component 10 is connected to the flat flexible cable 12.

The lower part 30 has a flat upper surface and, similarly to the previous embodiment, is formed with a receiving portion 38a for receiving the end of the flat flexible cable 12, and extends from the receiving portion 38a to the other end to extend the conductor. Grooves 40 for receiving 18 are formed parallel to each other. In addition, holes 34a and 34b that fit into protrusions 36a and 36b described later are formed with the groove 40 interposed therebetween.

The upper part 32 has a flat lower surface joined to the upper surface of the lower part 30, and is formed with a receiving part 38 a for receiving the end 14 of the flat flexible cable 12 together with a receiving part 38 a of the lower part 30. Protrusions 36a and 36b are formed on the lower surface of the upper part 32 to be inserted into the holes 34a and 34b of the lower part 30, respectively, and hooks are provided at the tips of the protrusions 36a and 36b.

The projections 36a and 36b are inserted into the holes 34a and 34b of the lower part 30 as described above. That is, the holes 34a and 34b of the lower part 30 and the projections 36a and 36b of the upper part 32 are fitted to each other, so that the lower part 30 and the upper part 32 are combined. Therefore, when the lower component 30 and the upper component 32 are combined with the end portion 14 and the conductor 18 of the flat flexible cable 12 fitted in the receiving portion 38a and the groove 40 of the lower component 30, respectively, the terminal processing component 10 Can hold the terminal of the flat flexible cable 12, and as a result, the terminal processing component 10 can be attached to the flat flexible cable 12.

Further, since the lower part 30 and the upper part 32 are firmly combined by the above-mentioned hook mechanism, the terminal of the flat flexible cable 12 is securely held by the terminal processing part 10 and the conductor is securely pressed.

It is formed. 6, the end portion 14 of the flat flexible cable 12 and the conductor 18 can be sandwiched between the lower component 42 and the upper component 44, similarly to the embodiment of FIG. Can be attached to the flat flexible cable 12.

When the lower part 42 and the upper part 44 are integrated by the hinge 46 in this manner, the parts are not lost and the work is facilitated. In the embodiment of FIG. 6 or FIG. 7, the terminal receiving portion or the conductor groove may be formed on only one of the upper part and the lower part, or may be formed on both of them. The terminal processing component 10 of the embodiment shown in FIGS. 8 and 9 is a modification of FIGS. 1 to 3 and is attached to a flat flexible cable 12 having a reinforcing plate 56 at the terminal.

As shown in FIG. 8, the flat flexible cable 12 has a reinforcing plate 56 at the end 14, and the reinforcing plate 56 contacts the lower surface of the conductor 18. In other words, the reinforcing plate 56 supports and protects the conductor 18 from below, thereby preventing the conductor 28 from being bent. The terminal processing component 10 of this embodiment includes a reinforcing plate receiving portion 58 formed integrally with the conductor groove 20, and the reinforcing plate receiving portion 58 receives the reinforcing plate 56. Therefore, the terminal processing component 10 of this embodiment can be attached to the flat flexible cable 12 similarly to the embodiment of FIGS.
