[0002] Optoelectronic composite cables include passive copper electrodes, optical cable reinforcing ribs, and optical cables. The passive copper conductors need to be connected to the positive and negative terminals during use. However, the lack of markings during the production of the wires makes it difficult to determine the positive and negative terminals of the two passive copper electrodes. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems by providing a mold for optoelectronic composite color striped cable.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a photoelectric composite color stripe cable mold, comprising an inner mold and an outer mold, one end of the outer mold being provided with a conical groove, the bottom of the conical groove being provided with a through hole; the inner mold being provided with a through hole corresponding to the forming hole, and both the forming hole and the through hole being provided along the axial direction of the conical groove, the forming hole being a strip-shaped structure, the through holes including a plurality of holes spaced apart along the length direction of the strip-shaped structure, and an injection hole being provided on the side wall of the outer mold, the injection hole being connected to one end of the forming hole along the length direction.

[0005] Furthermore, there is a dimensional difference between the two ends of the forming hole along its length.

[0006] Furthermore, the injection hole includes a second section communicating with the forming hole, a first section communicating with the other end of the second section, and a reduced-diameter section communicating with the first section and the second section.

[0007] Furthermore, the through hole includes two first through holes and two third through holes arranged in sequence at intervals, and also includes a second through hole disposed between the two third through holes. The first through holes are used for passive copper wires to pass through, the two third through holes are used for optical cable reinforcing ribs to pass through, and the second through hole is used for optical cables to pass through.

[0008] Furthermore, the forming hole includes a first rectangular hole, a second rectangular hole, and a connecting portion connecting the two, wherein the width of the first rectangular hole is greater than the width of the second rectangular hole.

[0009] Furthermore, along the axial direction of the conical groove, the through hole has an orthographic projection on the inner mold end face, the two first through holes correspond to the projection areas of the first rectangular hole, and the second through hole and the two third through holes correspond to the projection areas of the second rectangular hole.

[0010] Furthermore, a first cone is coaxially arranged at one end of the inner mold near the outer mold, and a mold core is detachably and fixedly arranged at the end of the first cone, with the through hole provided on the mold core.

[0011] Furthermore, the end of the first cone is coaxially provided with an installation groove, the outer circumferential surface of the mold core is provided with a threaded hole, a positioning screw is connected to the threaded hole by an internal thread, and a positioning hole corresponding to the threaded hole is provided on the side wall of the installation groove. The radius of the positioning hole is larger than the radius of the threaded hole, and the end of the positioning screw is positioned and engaged with the positioning hole.

[0012] Furthermore, the outer circumferential surface of the mold core is provided with a countersunk hole, which is coaxially arranged with the threaded hole and has the same radius as the positioning hole.

[0013] Compared with the prior art, the optoelectronic composite color stripe cable mold disclosed in this utility model has the following advantages: By setting the injection hole, colored injection molding compound is injected through the injection hole during cable injection molding, so that one side of the cable has a stripe of color, achieving the identification effect. At the same time, multiple through holes are arranged at intervals along the length of the stripe structure, which can allow different cable components to pass through in an orderly manner, ensuring the regularity of the cable molding. When two passive copper wires are set, the passive copper wire connected to the positive electrode can be placed close to the color strip, making it easier to distinguish the positive and negative electrodes of the passive copper wires. This solves the problem in the prior art where the lack of marking during wire production makes it difficult to determine the positive and negative electrodes, facilitates the subsequent docking operation, and improves work efficiency.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Example 1 Please refer to Figure 1-4 This utility model provides a mold for a photoelectric composite striped cable, including an inner mold 2 and an outer mold 1. One end of the outer mold 1 is provided with a conical groove 10, and a forming hole is formed through the bottom of the groove 10. The inner mold 2 is provided with a through hole 22 corresponding to the forming hole 12, and both the forming hole 12 and the through hole 22 are arranged along the axial direction of the conical groove 10. The forming hole 12 has a strip-shaped structure, and the through holes 22 include a plurality of holes spaced apart along the length direction of the strip-shaped structure. An injection hole 11 is provided on the side wall of the outer mold 1, and the injection hole 11 is connected to one end of the forming hole 12 along its length direction. Specifically, refer to... Figure 1 - Figure 6 The mold provided in this application includes an inner mold 2 and an outer mold 1, both of which are cylindrical structures. A conical groove 10 is coaxially provided at one end of the outer mold 1, and a first cone 20 is coaxially provided at one end of the inner mold 2. The larger end of the conical groove 10 is the inlet end, and the end of the forming hole 12 furthest from the conical hole is the outlet end. (Reference) Figure 4This application addresses the issue of the lack of markings on the forming hole 12, which is an elongated structure. Multiple through holes 22 are spaced apart along the length of the elongated forming hole 12, and an injection hole 11 is provided on the side wall of the outer mold 1. By using the injection hole 11, colored injection molding compound is injected during cable injection molding, creating a colored stripe on one side of the cable for identification. Simultaneously, the multiple through holes 22 spaced apart along the length of the stripe structure allow different cable components to pass through in an orderly manner, ensuring the regularity of the cable molding. When two passive copper wires are used, the passive copper wire connected to the positive terminal can be placed close to the colored stripe, making it easier to distinguish the positive and negative terminals of the passive copper wires. This solves the problem in the prior art where the lack of markings during wire production makes it difficult to determine the positive and negative terminals, facilitating subsequent connection operations and improving work efficiency.

[0028] Furthermore, as a specific implementation method, refer to Figure 3 , Figure 4 The two ends of the forming hole 12 along the length direction have different dimensions. Specifically, the explanation for the difference in dimensions between the two ends of the forming hole 12 along the length direction is that the widths of the two ends of the forming hole 12 are not equal or the contours are inconsistent. This application adopts a setting method in which the widths of the two ends of the forming hole 12 are not equal. Through the above setting method, the cross-section of the formed cable can also be a long strip with unequal widths at both ends, so that the passive copper electrode can be distinguished according to the difference in shape.

[0029] Furthermore, as a specific implementation method, refer to Figure 2 The injection hole 11 includes a second segment 111 communicating with the forming hole 12, a first segment 110 communicating with the other end of the second segment 111, and a reduced-diameter segment connecting the first segment 110 and the second segment 111. Specifically, the injection hole 11 includes a second segment 111 communicating with the forming hole 12, a first segment 110 communicating with the other end of the second segment 111, and a reduced-diameter segment connecting the first segment 110 and the second segment 111. This three-segment structure of the injection hole 11 with the reduced-diameter segment can provide a certain buffering and pressurizing effect on the injected outer sheath material. The first segment 110 can hold more material, and the reduced-diameter segment can increase the speed and pressure of the material entering the second segment 111, allowing the material to enter the forming hole 12 more smoothly and fill it, reducing the pressure loss of the material during the injection process, ensuring the filling effect of the material, and thus ensuring the forming quality of the cable outer sheath color stripe.

[0030] Furthermore, as a specific implementation method, refer to Figure 3 , Figure 4The through-hole 22 includes two first through-holes 220 and two third through-holes 222 arranged sequentially at intervals, and a second through-hole 221 disposed between the two third through-holes 222. The first through-holes 220 are used for passive copper wires to pass through, the two third through-holes 222 are used for optical cable reinforcing ribs to pass through, and the second through-hole 221 is used for optical cables to pass through. Specifically, by dividing the through-holes 22 into specific functions, the passive copper wires, optical cable reinforcing ribs, and optical cables can pass through their respective through-holes, realizing the orderly arrangement of different cable components, avoiding mutual entanglement or interference between components, ensuring the stability of the internal structure of the cable, and also facilitating the positioning and control of each component during the production process, improving the reliability of production. Furthermore, by placing the injection hole 11 on the side close to the first through-hole 220, the two passive copper poles of the formed cable can be placed close to the side of the color strip. At this time, the passive copper wire close to the color strip can be set as the positive pole, and the color strip can be set as red, which can more intuitively distinguish the polarity.

[0031] Furthermore, the molding hole 12 includes a first rectangular hole 120, a second rectangular hole 121, and a connecting portion 122 connecting the two. The width of the first rectangular hole 120 is greater than the width of the second rectangular hole 121. Specifically, by setting the molding hole 12 to this structure, which consists of rectangular holes of different widths connected by the connecting portion 122, the dimensional difference between the two ends of the molding hole 12 is further clarified. During production, the portion of the cable sheath corresponding to the first rectangular hole 120 will form a wider structure, and the portion corresponding to the second rectangular hole 121 will form a narrower structure. This obvious width difference serves as a more intuitive identifier, making it easier for operators to quickly identify the positive and negative terminals of the passive copper electrode. At the same time, the setting of the connecting portion 122 ensures the overall continuity of the molding hole 12, allowing the sheath material to transition smoothly and avoiding stress concentration on the sheath. On the other hand, it can also reduce the amount of injection molding material used, thereby reducing the production cost of the cable.

[0032] Further, refer to Figure 4 A first constriction 1200 is provided in the middle area of ​​the first rectangular hole 120, and a second constriction 1210 is provided in the middle area of ​​the second rectangular hole 121. The second through hole 221 is a strip hole, which is set corresponding to the second constriction. By setting the first constriction and the second constriction, the amount of cable sheath used can be further reduced.

[0033] Furthermore, as a specific implementation, along the axial direction of the tapered groove 10, the through hole 22 has an orthographic projection on the end face of the inner mold 2, the two first through holes 220 correspond to the projection area of ​​the first rectangular hole 120, and the second through hole 221 and the two third through holes 222 correspond to the projection area of ​​the second rectangular hole 121. Specifically, by setting the above correspondence, the positions of the through hole 22 and the forming hole 12 are matched, so that the passive copper wire passing through the first through hole 220 corresponds to the outer sheath portion formed by the first rectangular hole 120 in the forming hole 12, and the optical cable and optical cable reinforcing rib passing through the second through hole 221 and the third through hole 222 correspond to the outer sheath portion formed by the second rectangular hole 121. This ensures the correspondence between the internal components of the cable and the outer sheath structure, so that the shape difference of the outer sheath can accurately correspond to the position of the passive copper wire. Since the diameter of the passive copper wire is large and the diameter of the optical cable and reinforcing rib is small, the large diameter passive copper wire can correspond to the wide first rectangular hole 120, and the small size optical cable and reinforcing rib can correspond to the small size second rectangular hole 121. This method can ensure that the formed cable sheath can fully wrap the internal wire bundle, and can also reduce the amount of material used for the cable sheath as much as possible.

[0034] Example 2 This utility model provides a mold for an optoelectronic composite color striped cable, for reference. Figures 7-11 Furthermore, a first cone 20 is coaxially disposed at one end of the inner mold 2 near the outer mold 1. A mold core 21 is detachably fixed at the end of the first cone 20, and the through hole 22 is disposed on the mold core 21. Specifically, the first cone 20 facilitates the engagement of the inner mold 2 with the tapered groove 10 of the outer mold 1, improving the positioning accuracy between the two. The mold core 21 is detachably fixed, so when different specifications or types of cables need to be produced, only the mold core 21 with the corresponding through hole 22 needs to be replaced, without replacing the entire inner mold 2, reducing production costs and improving the versatility and flexibility of the mold. At the same time, the through hole 22 is disposed on the mold core 21, which facilitates the processing and maintenance of the through hole 22.

[0035] Furthermore, the end of the first cone 20 is coaxially provided with an installation groove 202, the outer peripheral surface of the mold core 21 is provided with a threaded hole 210, the threaded hole 210 is internally threaded with a positioning screw 23, the side wall of the installation groove 202 is provided with a positioning hole 201 corresponding to the threaded hole 210, the radius of the positioning hole 201 is larger than the radius of the threaded hole 210, and the end of the positioning screw 23 is positioned and engaged with the positioning hole 201.

[0036] For details, please refer to Figures 8-11As a specific implementation, the end of the first cone 20 is coaxially provided with an installation groove 202, the outer peripheral surface of the mold core 21 is provided with a threaded hole 210, the threaded hole 210 is internally threaded with a positioning screw 23, the side wall of the installation groove 202 is provided with a positioning hole 201 corresponding to the threaded hole 210, the radius of the positioning hole 201 is larger than the radius of the threaded hole 210, and the end of the positioning screw 23 is positioned and engaged with the positioning hole 201. The outer diameter of the positioning screw 23 and the inner diameter of the positioning hole 201 are matched with an accuracy of 0.01-0.05 mm to ensure radial positioning effect. The mold core 21 is installed and positioned through the mounting groove 202. Combined with the matching of the positioning screw 23 with the threaded hole 210 and the positioning hole 201, the mold core 21 is detachably fixed at the end of the first cone 20. The radius of the positioning hole 201 is larger than the radius of the threaded hole 210, which facilitates the smooth entry of the end of the positioning screw 23 into the positioning hole 201 and achieves positioning. This fixing method has a simple structure and is easy to operate. It can ensure the stability and accuracy of the installation of the mold core 21 and avoid displacement of the mold core 21 during the production process, which would affect the forming quality of the cable.

[0037] Furthermore, both the positioning hole 201 and the threaded hole 210 on the outer circumferential surface of the mold core 21 are provided to ensure that the mold core 21 can be circumferentially positioned when positioned by the positioning screw 23.

[0038] Furthermore, in a preferred embodiment, the outer peripheral surface of the mold core 21 is provided with a countersunk hole 211, which is coaxially arranged with the threaded hole 210, and the countersunk hole 211 has the same radius as the positioning hole 201. (Reference) Figure 10 , Figure 11 The countersunk hole 211 allows the head of the positioning screw 23 to sink into it. At this time, part of the end of the positioning screw 23 sinks into the countersunk hole 211 and part is located in the positioning hole 201, which can better position the mold core 21 and make the mold core 21 and the inner mold 2 better correspond, thus ensuring the accuracy of positioning.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
