[0136] Therefore, the plug module 12, combined with the socket module 16, allows the first grounding wire 28 of the flexible flat cable 2 to be connected to the grounding terminal of the printed circuit board 4 through the first grounding piece 128, the first body 122, and the second body 162 by increasing the grounding area. (See also...) Figure 13 As shown. In addition to this embodiment, if the extended grounding module 14 is added, after the plug module 12 is combined with the socket module 16, the first grounding wire 28 of the flexible flat cable 2 can be further connected to the first grounding plate 128, 128', the first body 122 and the second body 162 through the third grounding plate 148 and the third body 142, thereby expanding the grounding area and connecting to the grounding terminal of the printed circuit board 4.

[0137] Also refer to Figures 14(a) and 14(b) and Figures 15(a) and 15(b), Figure 14(a) illustrating the present invention. Figure 1 Another embodiment of the flexible flat cable is shown in the perspective view; Figure 14(b) is a top view and a partial enlarged view illustrating the flexible flat cable of Figure 14(a) of the present invention; Figure 15(a) is an illustration of the present invention. Figure 1 A perspective view of another embodiment of the flexible flat cable; and FIG15(b) is a top view and a partial enlarged view illustrating the flexible flat cable of FIG15(a) of the present invention.

[0138] In Figures 14(a) and 14(b), the end of the flexible flat cable 2' is disposed at the plug module 12, exposing the first terminal 26'. The plurality of first terminals 26' have a high-speed transmission area HAS, a positive power supply area PSA, and a negative power supply area PSC. The high-speed transmission area HAS is located between the positive power supply area PSA and the negative power supply area PSC. The plurality of first terminals 26' located in the high-speed transmission area HAS transmits signals by transmitting a transmission signal S between two ground signals G. In this embodiment, as can be seen from the partial enlarged view, there are two ground signals G on each side of the two transmission signals S, i.e., an arrangement of GGSSGGSS. In other embodiments, the transmission signal S and the ground signal G can be arranged and configured in other ways, which is not limited here.

[0139] It is worth noting that the ends of the plurality of first terminals 26' in the high-speed transmission zone HAS are not flush with the ends of the plurality of first terminals 26' in the positive power supply zone PSA and the negative power supply zone PSC, i.e., the ends of the plurality of first terminals 26' in the high-speed transmission zone HAS, the positive power supply zone PSA and the negative power supply zone PSC (referring to the free ends in Fig. 14(b)) are arranged in a non-flush manner. In this embodiment, if the ends of the plurality of first terminals 26' in the high-speed transmission zone HAS (referring to the horizontal direction of the drawing) are taken as a baseline, the ends of the plurality of first terminals 26' in the negative power supply zone PSC are closer to the baseline than the ends of the plurality of first terminals 26' in the positive power supply zone PSA. Therefore, when the plug module 12 is combined with the aforementioned socket module 16, the plurality of first terminals 26' in the high-speed transmission zone HAS will first contact the second terminals 166, then the second terminals 166 contact the plurality of first terminals 26' in the negative power supply zone PSC, and finally the plurality of first terminals 26' in the positive power supply zone PSA contact the second terminals 166, which can achieve the effect of, for example, hot insertion.

[0140] Similarly, in Figs. 15(a) and 15(b), the ends of the flexible flat cable 2" are also provided on the plug module 12, and the first terminals 26" are exposed. The plurality of first terminals 26" also have a high-speed transmission zone HAS', a positive power supply zone PSA' and a negative power supply zone PSC'. The descriptions of the parts are as described above and will not be repeated here. However, the embodiment is different from the aforementioned embodiment in that, if the ends of the plurality of first terminals 26' in the high-speed transmission zone HAS' (referring to the horizontal direction of the drawing) are taken as a baseline, the ends of the plurality of first terminals 26' in the negative power supply zone PSC' are on the same baseline as the ends of the plurality of first terminals 26' in the high-speed transmission zone HAS', while the ends of the plurality of first terminals 26' in the positive power supply zone PSA' are at a distance from the baseline. Therefore, when the plug module 12 is combined with the aforementioned socket module 16, the plurality of first terminals 26' in the high-speed transmission zone HAS' and the negative power supply zone PSC' will first contact the second terminals 166, and then the plurality of first terminals 26' in the positive power supply zone PSA' contact the second terminals 166, which can also achieve the effect of, for example, hot insertion.

[0141] In this embodiment, the flexible flat cables 2, 2' can also have notches 21 formed on both sides thereof for being provided on the plug module 12 having a stop block (not shown) to stop the flexible flat cables 2, 2' on the plug module 12.

It is noted that variations and substitutions, which are equivalent to those described and illustrated, are intended to be encompassed within the scope of the present application. Accordingly, the scope of the present application is to be limited only by the following claims.
