The 4 wires 113 are covered by the wire sleeve 111 to form the cable 11, and the wire sleeve 111 is usedThe thermoplastic polyurethane (namely TPU) material with good wear resistance, high tear resistance and high bending strength is used for cladding and protecting, so as to achieve the bending resistance and the water resistance of the cable 11.
In step S20: after removing the wire sleeve 111 at one end of the cable 11, the wire sleeve 111 coated on the cable 11 forms a cut end, the cut end of the cable 11 exposes the plurality of wires 113, and the plurality of wires 113 are divided into a first wire group 1131 and a second wire group 1132. Of which two are 0.25mm 2 The wires 113 of the cross-sectional area are divided into a first wire set 1131 of two 1.8mm 2 The wires 113 of the sectional area are divided into a second wire group 1132.
In step S30: two sleeves 13 are respectively sleeved on the first wire set 1131 and the second wire set 1132. The sleeve 13 is made of polyurethane (i.e., PUR), and the sleeve 13 is used to cover the first wire set 1131 and the second wire set 1132, so that one end of the sleeve 13 is respectively covered at the position of the first wire set 1131 near the incision end and the position of the second wire set 1132 near the incision end, so as to be used as a waterproof and dustproof structure of the first wire set 1131 and the second wire set 1132.
In this embodiment, after step S20 or step S30, the user may further sleeve one end of the two bellows 15 on the other end of the sleeve 13, and fix the band at the overlapping position of the sleeve 13 and the bellows 15. The bellows 15 is divided into two outer diameters, i.e. a diameter phi 7 and a diameter phi 3, wherein the bellows 15 with the diameter phi 7 is sleeved on the sleeve 13 outside the first wire set 1131, and the bellows 15 with the diameter phi 3 is sleeved on the sleeve 13 outside the second wire set 1132.

The first wire set 1131 completed by the assembled ribbon and the second wire set 1132 completed by the assembled ribbon are placed into a second profiling jig, the size, the appearance, the direction of the assembled ribbon and the assembly accuracy of the machined wire are checked by the second profiling jig, when the condition of the machined cable 11 meets the standard requirement of the second profiling jig, the contact switch in the second profiling jig is triggered, and at the moment, the cylinder is unlocked, so that the cable 11 with the sleeve 13 and the corrugated pipe 15 fixed with the ribbon can be taken out, and the problems of wrong installation, missing installation or incorrect assembly direction of the ribbon are prevented.
The present embodiment is secured to the sleeve 13 and the bellows 15 by a tie strap. Furthermore, the heat shrinkage tube 17 is sleeved on the outer side of the ribbon, and the heat shrinkage tube 17 is baked, so that the heat shrinkage tube 17 is fastened on the outer side of the overlapping part of the ribbon, the sleeve 13 and the corrugated tube 15, and the heat shrinkage tube 17 can further strengthen the connection strength between the sleeve 13 and the corrugated tube 15 and also can improve the waterproof and dustproof strength between the sleeve 13 and the corrugated tube 15.
As described above, the terminal member is crimped to the end of the first wire set 1131 away from the cut end and the end of the second wire set 1132 away from the cut end. The terminal member is assembled in the connection housing to form the connector 19, and the other end of the bellows 15 is fixed in the connection housing.

In the present embodiment, the user can further sleeve the rubber tube 21 (i.e., EPDM) outside the cable 11 having the wire sleeve 111, with one end of the rubber tube 21 being close to the cut end. The user injection-molds one end of the rubber tube 21 and one end of the two sleeves 13 adjacent to the cut ends. Among them, the rubber tube 21 can serve as a protective sheath for protecting the cable 11 against external force. Further, a rubber sleeve 23 is assembled to the other end of the rubber tube 21 using a reamer, the position of the cable 11 is fixed using the rubber sleeve 23, and water inflow into the rubber tube 21 and protection of the cable 11 are prevented. As described above, the rubber tube 21 is moved to the position where the brackets 25 need to be riveted, the brackets 25 to be assembled are put into the assembly jig, and the brackets 25 are press-fitted and fixed to the rubber tube 21 using the assembly jig.
In step S40: the cut ends of the cable 11 and the ends of the two sleeves 13 adjacent to the cut ends are injection molded into the injection molded structure 27 to fix the angle between the first conductor set 1131 and the second conductor set 1132 relative to the cable 11 with the wire jacket 111. In this embodiment, after the first wire set 1131 and the second wire set 1132 are positioned at the end with the connecting shell and the end with the connecting shell, the cut ends of the cable 11 and the ends of the adjacent cut ends of the two sleeves 13 are correspondingly placed in the injection mold, so that the cable 11, the first wire set 1131 and the second wire set 1132 in the injection mold are not in a bending state, and the cable 11, the first wire set 1131 and the second wire set 1132 are tightly pressed by the structure of the injection mold, so that the cable 11, the first wire set 1131 and the second wire set 1132 can be bent corresponding to the outline shape of the injection mold, and the angle between the first wire set 1131 and the second wire set 1132 relative to the cable 11 with the wire sleeve 111 is fixed. Finally, the thermoplastic polyurethane (i.e., TPU) material which has been heated to a molten state at a high temperature is injected into the cavity of the injection mold at a high pressure and a high speed by using a screw injection molding machine, and then the injection structure 27 with a desired shape is obtained through pressure maintaining and cooling.

Further, the fixing portion 273 is located at the other side of the body portion 271. After the cable 11 is manufactured, the cable 11 can be correspondingly assembled to the mounting hole of the vehicle through the fixing portion 273 of the injection structure 27, so that the cable 11 can be conveniently fixed, and the connector 19 of the branch wire 113 of the cable 11 is used for being connected to the vehicle interior system.
In the present embodiment, the cut ends of the cable 11 and one end of the two bushings 13 adjacent to the cut ends are injection-molded and combined into the injection-molded structure 27 by an injection mold. The injection molding structure 27 is designed to be opened according to the requirement of a user, and the angle between the first wire set 1131 and the second wire set 1132 can be adjusted by changing the mold structure. In addition, the injection structure 27 has a larger shape, and shrinkage, unsaturation and other conditions occur during the injection process, so that the perforations 270 with different shapes and sizes are designed on the injection structure 27, and the reject ratio of the product can be reduced.
Please refer to fig. 5 and fig. 6 together, which are a schematic diagram and another schematic diagram of a second embodiment of an injection molding structure of the present application. As shown in the drawing, the difference of the present embodiment compared to the first embodiment is the angle between the first wire set 1131 and the second wire set 1132 with respect to the cable 11 having the wire jacket 111 and the structure of the fixing portion. The angle between the first wire set 1131 and the second wire set 1132 with respect to the cable 11 having the wire jacket 111 can be fixed at the bending portion 272A of the present embodiment.

Furthermore, the fixing structure of the fixing portion 273A is different from that of the fixing portion 273, and the fixing structure of the fixing portion 273A can be designed according to the requirement of the user, so that the fixing portion 273A of the injection structure 27A can be assembled in the mounting hole of the vehicle. In addition, the injection structure 27A of the present embodiment also has a main body 271A and a through hole 270A, which can be designed correspondingly according to the shape of the injection structure 27A.
