[0027] First, as attached Figure 2 , Attachment Figure 4 and attached Figure 5 As shown in , when the wiring harness cable is used, since the installation head 9 is fixedly connected with the front end of the wire 4, and then the slider 13 is pushed to slide on the installation head 9, the guide rod 14 is fitted with the inner side wall of the sliding rod 10, and since the side wall of the guide rod 14 is arranged in an inclined state, the guide rod 14 drives the sliding rod 10 to rise and fall, and at the same time, the sliding rod 10 drives the spring 11 to be compressed, and then the sliding rod 10 drives the fixing block 12 to slide inside the installation head 9, so that the external male head is inserted into the inside of the installation head 9, so that the side wall of the fixing block 12 is arranged in an inclined state, so that the external male head slides over the fixing block 12, so that the fixing block 12 fixes the external male head, so that the external male head is connected with the wire 4, so as to transmit it;

[0028] As attached Figure 1 and attached Figure 3 As shown in the figure, when the wiring harness cable is installed and arranged, the outer sheath 1 is bent or twisted during installation, and the inner parts of the outer sheath 1 are bent or twisted at the same time, and the rubber filling rod 2 and the sheath 3 are also bent or twisted. Since the insulating layer 8 and the shielding layer 6 inside the outer sheath 1 are both arranged in a semi-arc state, and the insulating layer 8 is arranged in a stainless steel foil material state, and the shielding layer 6 is arranged in a steel wire material state, and the insulating layer 8 is in contact with the inner wall of the outer sheath 1, and the insulating layer 8 and the shielding layer 6 are both arranged in a contact state with the flame retardant layer 7, the outer sheath 1 provides higher toughness when it is bent or twisted, and the outer sheath 1 is reset by the flammability of the shielding layer 6 and the insulating layer 8 when it is bent or twisted;
