'Other components (eg shielded housing) can be used for overlap. 200919494 The month of the month refers to the sixth figure, which is not referred to as the use state of the flexible cable of the present invention. As shown in the figure: the hair duck is a soft cable combined with the metal composite layer 31, and the metal composite The insulating interlayer 311 of the layer 31 is provided with an opening 31 〇, so that the metal interlayer 312 located at the opening 310 is exposed, and the opening 310 is adjacent to the contacts 23 and is located on the same side as the contacts 23, When the flexible cable is inserted into the insulative housing 9 of the electrical connector 9, the plurality of contacts 23 of the flexible cable can be electrically connected to the conductive terminals 91 in the insulative housing 90. The grounding strip 921 of the body 92 can be overlapped on the surface of the metal interlayer 312 at the opening 310 of the metal composite layer 31, and the static electricity on the shielding shell 92 can be led out through the metal interlayer 312 to achieve the grounding effect. In the embodiment of the present invention, the metal composite layer 31 is pre-heat pressed onto the top surface of the wire layer 21. However, the metal composite layer 31 may also be bonded to the bottom surface of the insulating layer 22 in advance, or may be bonded to the wire layer 21 at the same time. The top surface and the bottom surface of the insulating layer 22 are then laser-cut an opening 31 分别 on the surface of the insulating interlayer 311 of the metal composite layer 31, and the metal interlayer 312 at the opening 31 is exposed to the outside to make the flexible cable The upper surface or the lower surface or the upper and lower surfaces can be used for the grounding piece 921 of the shielding shell 92 to be used for the grounding effect. The position of the opening 31 can be adapted to the shielding shell 92. The position of the grounding piece 921 is changed, and the grounding piece 921 of more different positions can be used for overlapping. It can be seen from the above description that the greatest feature of the present invention is that after a metal composite layer is pre-bonded to the insulating layer, 'the laser cutting step is used to make the insulating interlayer of the gold 200919494 composite layer be cut open α, so that the insulating clip is under the reed The metal interlayer is exposed to the outside for the shielding shell to be used, thereby achieving the grounding effect and improving the practicality of the flexible cable. However, the above description is only a preferred embodiment of the present invention, and thus the patent of the present invention is not limited thereby, and therefore equivalent changes in the use of the Mingfa County and the contents of the schema are all included in the same reason. Within the scope of the present invention, Chen Ming is incorporated. In summary, the invention of the new line and its manufacturing green use has significant performance enhancement, in line with novelty, creativity and progress = patent requirements, New Zealand proposed towel, hope that the party will give this book as soon as possible Secondly, in order to protect the inventor's hard work, if there is any doubt in the Xiaoxuan, the month will not be a letter, and the inventor will try his best to cooperate with him.
