[0002] With the growing demand for power transmission, bundled three-core cables are widely used in various power systems as an efficient power transmission solution. The existing bundled three-core cables are mainly composed of three mutually insulated conductor cores, an insulation layer, and a ribbed belt connecting these cores. This type of cable design is designed to provide stable power transmission and reduce the complexity of the installation process.

[0003] However, the existing three-core cables have some limitations in practical applications. In particular, the design of the reinforcement belt is an integral structure, which means that when the cable is divided and installed, it is necessary to manually use tools such as knives to divide the reinforcement belt. This process is not only time-consuming and labor-intensive, but also increases the installation cost and labor intensity, and also increases the safety risks during the construction process.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Reference Figure 1 , Figure 4 , Figure 5 , which is the first embodiment of the present invention, provides a bundled three-core cable, including three cables 101, and two adjacent cables 101 are fixed to each other by a reinforcing belt 102, wherein the reinforcing belt 102 is provided with a plurality of penetrating dot matrix holes 103 and diamond holes 104.

[0035] In order to solve the problem that the existing bundled three-core cable 100 needs to use a knife to split the reinforcement belt 102 during the installation process, we designed a new reinforcement belt 102 structure, which includes a number of carefully arranged holes. These holes allow the reinforcement belt 102 to be easily torn apart by hand, thereby greatly improving the convenience and efficiency of installation.

[0036] The characteristics of the 102 hole design of the tendon belt are as follows:

[0037] Dot matrix holes 103: We have designed a series of dot matrix holes 201c on the reinforcing band 102. These holes 201c not only connect the cables 101, but also provide easy-to-tear points. Since the layout of the holes 201c is in a dot matrix, they form multiple potential weak points on the reinforcing band 102, so that the user can easily tear the reinforcing band 102 along these points without using any tools.

[0038] Diamond holes 104: Diamond holes 104 are also provided on the tendon band 102. The design of these holes has dual advantages. First, the diamond holes 104 provide a large space so that the user can easily pinch and tear the tendon band 102 with his fingers. Second, the design of the diamond holes 104 also facilitates the bundling of the bundled three-core cable 100 because they provide a natural anchor point that can be used to fix the cable and ensure stability during installation and use.

[0039] Through this innovative design of the reinforcing band 102, we not only improve the installation efficiency of the bundled three-core cable 100, but also reduce the safety risks during the installation process. Users no longer need to carry and use knives, and can quickly complete the cable segmentation and installation by simply tearing the reinforcing band 102 by hand. In addition, this design also maintains the electrical performance and mechanical strength of the cable, ensuring the reliability and safety of power transmission.

[0040] In summary, our rib strip 102 design achieves fast, convenient and safe cable installation by introducing the dot matrix holes 103 and the diamond holes 104 .

[0041] One lattice strip hole 103 and one diamond-shaped hole 104 form a basic unit. A plurality of basic units are arranged at equal intervals on the rib band 102. In each basic unit, the lattice strip hole 103 and the diamond-shaped hole 104 are arranged at intervals.

[0042] Several basic units are arranged at equal intervals on the rib band 102, which means that there is a fixed and uniform distance between each basic unit. This design allows the rib band 102 to have a consistent tearing point throughout its entire length, making it easy to tear quickly at any position. In each basic unit, the dot matrix holes 103 and the diamond holes 104 are arranged at intervals. This design not only ensures the connection strength of the rib band 102, but also provides multiple tearing points, so that the user can select the nearest tearing point for operation as needed.

[0043] The reason for adopting the basic unit design is that it is convenient for users to perform tearing operations from the nearest basic unit. Since each basic unit contains the holes required for tearing, users do not need to find a specific tearing point, but only need to select the nearest basic unit to start the tearing operation. By arranging the dot matrix holes 103 and the diamond holes 104 at intervals in the basic unit, the tearing length can be kept small, which means that each tearing operation only needs to target one basic unit instead of the entire reinforcing band 102. This can reduce the damage that may be caused to the cable during the tearing process, and also reduce the waste of materials. In summary, this reinforcing band 102 design forms basic units by combining the dot matrix holes 103 and the diamond holes 104, and arranging these basic units at equal intervals on the reinforcing band 102, which not only improves the installation efficiency of the bundled three-core cable 100, but also ensures the convenience of the tearing operation and the safety of the cable.

[0044] In the design of the bundled three-core cable 100, the shape and layout of the diamond hole 104 play an important role in the cable binding and tearing operations. The following is an explanation of the design feature that "the long diagonal of the diamond is parallel to the cable 101": The shape of the diamond hole 104 has two diagonals, one of which is a longer diagonal and the other is a shorter diagonal. The design of the diamond hole 104 forms an effective binding point on the tendon 102, and also provides space for easy tearing.

[0045] The design of the long diagonal of the diamond hole 104 being parallel to the cable 101 means that when tying, the direction of the long diagonal is consistent with the arrangement direction of the bundled three-core cable 100. The advantages of this parallel layout are: (1) The long diagonal is parallel to the cable 101, which can effectively reduce the contact area between two adjacent cables 101, so that the cables 101 can be better separated. When tearing the reinforcing tape 102, the user can operate along the edge of the diamond hole 104, reducing the impact on the cable 101 during tearing. This design makes the tearing process smoother and reduces the potential risk of damage to the cable insulation layer. (2) When tying the whole cable, the user can tie from the diamond hole 104. Since the design of the diamond hole 104 allows a certain amount of space for contraction, the cable tie can be tightly fixed at the contracted position of the bundled three-core cable 100 after tying, preventing the cable tie from moving during use. This stability ensures that the cable will not loosen or move due to loose tying during operation. The design of the diamond-shaped hole 104 not only provides an anchor point for binding, but also allows a certain amount of space to shrink toward the middle during binding. The existence of this shrinkage space enables the cable tie to better fit the cable 101, thereby enhancing the firmness and stability of the binding.

[0046] In summary, the design of the long diagonal line of the diamond hole 104 being parallel to the cable 101 plays an important role in the binding and tearing operations of the bundled three-core cable 100. It not only reduces the contact area between the cables 101 and facilitates the tearing operation, but also ensures the stability and safety of the binding, thereby improving the overall performance and service life of the cable.

[0047] Each dot matrix strip hole 103 is composed of a plurality of strip holes, and the plurality of strip holes are arranged at equal intervals.

[0048] The dot matrix hole 103 is a specially designed hole, which consists of a plurality of strip holes, which are arranged in a straight line at equal intervals on the rib band 102. Each strip hole is an elongated opening, which can exist alone or be connected to each other to form a series of breakpoints, which create multiple potential weak points on the rib band 102. This design allows the rib band 102 to be easily torn along these strip holes when it needs to be torn, without the need to use any tools, greatly simplifying the installation and maintenance process of the cable. This evenly distributed tearing point also helps to maintain the neat appearance of the cable, because all tearing operations will be performed along the same pattern, reducing irregular damage that may be caused during the tearing process.

[0049] The cable 101 includes a core 101 a and an insulating shell 101 b , and the insulating shell 101 b and the rib band 102 are integrally formed.

[0050] The rib band 102 is a reinforcing structure used to fix and protect the core 101a in the cable 101. It extends along the length of the cable 101 and fixes the core 101a in place. The rib band 102 is usually made of the same insulating material to maintain the overall consistency and insulation performance of the cable. The insulating shell 101b and the rib band 102 are integrally formed, which means that during the manufacturing process, the insulating shell 101b and the rib band 102 are not manufactured separately and then assembled, but are formed simultaneously through a continuous manufacturing process. This integrated manufacturing method can improve production efficiency, reduce material waste, and ensure a close connection between the insulating shell 101b and the rib band 102, enhancing the overall mechanical strength and electrical performance. The one-piece molding process can ensure that there is no seam or gap between the insulating shell 101b and the rib band 102, which helps to improve the waterproof performance and mechanical damage resistance of the cable 101.

[0051] Reference Figure 1-Figure 7, which is the second embodiment of the present invention, and the difference between this embodiment and the first embodiment is: a three-hole parallel mold for making a bundled three-core wire, comprising a bundled three-core wire 100, a mold sleeve assembly 201, and a core assembly 202 installed in the mold sleeve assembly 201, and a hole opening assembly 203 is arranged between the mold sleeve assembly 201 and the core assembly 202, and the hole opening assembly 203 is used to open the through-dot matrix bar holes 103 and diamond holes 104. The front end of the core assembly 202 is set as a truncated cone portion 202a, and the mold sleeve assembly 201 covers the truncated cone portion 202a to form a material cavity 201a, and a feed pipe 201b connected to the material cavity 201a is arranged on the outer wall of the mold sleeve assembly 201. Three through holes 202b for the cable 101 to pass through are opened on the core assembly 202, and a bar hole 201c for the bundled three-core wire 100 to pass through is opened on the mold sleeve assembly 201.

[0052] Two groups of cutting wheels 203 a are arranged in parallel in the strip holes 201 c . Each group of cutting wheels 203 a corresponds to one rib strip 102 . Each group is provided with two symmetrical cutting wheels 203 a . The cutting wheels 203 a are used for cutting the lattice strip holes 103 .

[0053] During the production process of the bundled three-core cable 100, two groups of symmetrical cutting wheels 203a are specially designed in the strip holes 201c of the die sleeve assembly 201, each group corresponds to a position of the rib band 102, and are arranged in parallel to improve production efficiency. The main function of these cutting wheels 203a is to accurately cut out dot matrix strip holes 103 on each rib band 102 during the cable extrusion process. Since the cutting wheels 203a are symmetrically arranged, they not only ensure the uniformity and stability of cutting, but also help maintain the balance of production. Even if one of the cutting wheels 203a is worn or damaged, the other can continue to work to ensure the continuity of the production process. This design makes the bundled three-core cable 100 more convenient to install and maintain, because the dot matrix strip holes 103 on the rib band 102 allow the user to manually tear the rib band 102 without tools, thereby improving the installation efficiency and convenience of the cable.

[0054] Two groups of diamond blocks 203b are also arranged in parallel in the material cavity 201a, each group of diamond blocks 203b corresponds to a rib band 102, each group is provided with two symmetrical diamond blocks 203b, and each diamond block 203b slides along the limiting groove 201d of the mold sleeve assembly 201 through the connecting rod 203c, and a protrusion 203d is provided on the side of the cutting wheel 203a, and the protrusion 203d slides in the groove at one end of the connecting rod 203c, which is used to drive the diamond block 203b to reciprocate.

[0055] It should be noted that, in the production process of the bundled three-core wire 100, in addition to the setting of the cutting wheel 203a, two groups of diamond blocks 203b are specially designed in the material cavity 201a, each group of diamond blocks 203b corresponds to a rib band 102, and each group includes two symmetrical diamond blocks 203b, which slide in the limit groove 201d in the mold sleeve assembly 201 through the connecting rod 203c to achieve linear motion. At the same time, a protrusion 203d is set on the side of the cutting wheel 203a. This protrusion 203d is located in the groove at one end of the connecting rod 203c. Its function is to drive the connecting rod 203c, thereby driving the diamond block 203b to reciprocate. For details: please refer to Figure 6 Since the connecting rod 203c is arranged in the limiting groove 201d, the connecting rod 203c can only move left and right along the limiting groove 201d. At the same time, since one end of the diamond block 203b slides against the inner wall of the material chamber 201a, the connecting rod 203c will move left and right along the limiting groove 201d. Since the connecting rod 203c is provided with a groove, the protrusion 203d on one side of the cutting wheel 203a slides along the groove. When the protrusion 203d rotates in a circle with the cutting wheel 203a, the longitudinal displacement of the protrusion 203d is eliminated by sliding in the groove of the connecting rod 203c, and the lateral displacement drives the connecting rod 203c to make reciprocating linear motion in the limiting groove 201d (this part of the principle is similar to the cam mechanism). It should be noted here that the rotating shaft of the protrusion 203d and the cutting wheel 203a are respectively located on both sides of the cutting wheel 203a body, so as to avoid the rotating shaft from hindering the movement of the connecting rod 203c on one side. Since each connecting rod 203c makes reciprocating linear motion under the action of the protrusion 203d of the cutting wheel 203a and the limiting groove 201d, the diamond block 203b installed at the other end of the connecting rod 203c will also make reciprocating linear motion therewith. Since the same rib band 102 corresponds to two cutting wheels 203a, and the two cutting wheels 203a rotate in opposite directions, the protrusion 203d makes opposite movements, and the protrusion 203d drives the connecting rod 203c to move toward each other in the limiting groove 201d, so that the corresponding diamond blocks 203b will also move toward each other. In this process, when the two diamond blocks 203b move to the middle and close together, the rib band 102 in the extrusion process will be temporarily blocked, and then the diamond hole 104 will be formed during the molding process of the rib band 102. This design enables the diamond block 203b to block the rib band 102 at the appropriate position during the extrusion process to form the required diamond hole 104, thereby enhancing the cable binding function and providing an easy-to-tear structure. Through this precise mechanical linkage, the cable can form not only dot matrix holes 103 but also diamond holes 104 during extrusion, further improving the functionality and installation convenience of the bundled three-core cable 100.

[0056] In summary, the cutting wheel 203a and the diamond block 203b work together to form specific holes on the cable's reinforcing band 102. The cutting wheel 203a is responsible for the precise cutting of the dot matrix holes 103, while the diamond block 203b forms diamond holes 104 on the reinforcing band 102 that are convenient for binding and tearing. The setting of these structures not only improves production efficiency, but also ensures the convenience and safety of the bundled three-core cable 100 during installation and maintenance. At the same time, the setting of the cutting wheel 203a and the diamond block 203b does not require the separate setting of an additional power source, and only needs to move the existing bundled three-core cable 100 to achieve the purpose of driving its operation.

[0057] The workflow is as follows:

[0058] Installation of mold sleeve assembly 201 and mold core assembly 202:

[0059] First, insert the mold sleeve assembly 201 into the outer side of the mold core assembly 202 to ensure that the two are correctly connected to form a three-hole parallel mold 200. Then, install the three-hole parallel mold 200 on the equipment to prepare for the push-out of the cable 101 and the extrusion of the insulating material.

[0060] Cable 101 Rollout and Insulation Material Extrusion:

[0061] After the equipment starts operating, each cable 101 is pushed out from the three through holes 202b of the core assembly 202. At the same time, the extruder feeds the insulating material through the feed pipe 201b and introduces the insulating material into the material cavity 201a to wrap the cable 101 to form a bundled three-core cable 100.

[0062] Formation and discharge of bundled three-core wire 100:

[0063] After being formed, the bundled three-core wire 100 is pushed out along the strip hole 201 c of the mold sleeve assembly 201 .

[0064] Formation of holes in tendon band 102:

[0065] In the strip hole 201c of the die sleeve assembly 201, two symmetrical cutting wheels 203a are arranged at the position corresponding to each rib band 102. When the bundled three-core wire 100 is discharged, the cutting wheel 203a is driven to rotate and cuts a series of dot matrix strip holes 103 at the position of the rib band 102.

[0066] Formation of diamond-shaped holes 104:

[0067] A protrusion 203d is provided on the side of the cutting wheel 203a, and the protrusion 203d drives the connecting rod 203c to reciprocate in the limiting groove 201d. The reciprocating motion of the connecting rod 203c further drives the diamond block 203b to reciprocate. Two symmetrical diamond blocks 203b are provided at the position corresponding to each rib band 102. When the insulating rib band 102 is formed at this location, the diamond block 203b blocks the rib band 102, thereby forming a diamond hole 104 at the rib band 102.

[0068] Final product formation:

[0069] Through the above steps, a complete version of the bundled three-core cable 100 with the dot matrix holes 103 and the diamond holes 104 is finally formed.

[0070] In summary, this process describes in detail each step from the installation of the mold sleeve assembly 201 and the mold core assembly 202 to the formation of the bundled three-core wire 100, with particular emphasis on the key link of the formation of the holes in the rib band 102, ensuring that the production of the bundled three-core wire 100 is both efficient and meets design requirements.
