Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing technology, and in particular to a cable processing support fixture. Background Technology

[0002] In the existing cable manufacturing industry, the braided shielding layer before the sheath extrusion process often suffers surface damage during transport or friction with the sides of the reel, leading to the breakage and warping of the metal filaments, forming what is known as "slippery wires." This problem is particularly prominent in the subsequent sheath extrusion process—the warped metal wires can easily puncture the outer sheath, causing sheath damage, which in turn leads to serious quality hazards such as water ingress, partial discharge, or even spark breakdown, directly affecting the reliability and service life of the cable.

[0003] To address this issue, the industry commonly uses cloth strips or tapes to wrap around the cable core to suppress jumpers. However, this method has significant limitations in practical applications: if the wrapping is too tight, it can easily cause localized compression and deformation of the braided layer, resulting in "stuck wires"; if the wrapping is too loose, it cannot effectively fix the jumpers. Furthermore, the additional binding tension created by the cloth tape on the cable core can easily be transferred to the molten outer sheath during sheath extrusion, causing uneven outer diameter and forming "bamboo-like" surface defects, affecting the product's appearance and structural consistency.

[0004] Therefore, while existing processes solve the problem of wire skipping, they also introduce new quality control challenges, reflecting that there is still room for optimization in matching cable shielding protection with sheath extrusion processes. Finding a process method that does not damage the braided layer structure, does not interfere with sheath molding, and reliably fixes skipped wires has become a key aspect of improving cable production quality and efficiency.

[0005] In view of this, it is necessary to improve the existing methods in order to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cable processing support fixture to solve the problem that existing methods for preventing wire skipping easily affect the appearance and structural consistency of the product.

[0007] To achieve the above objectives, this utility model provides a cable processing support fixture, which includes a plurality of partitions spaced apart in a horizontal direction. The partitions are provided with through holes for cables to pass through, and the through holes on the partitions gradually decrease in size from one side to the other.

[0008] As a further improvement of this utility model, the through hole is a circular hole, and the through holes on the plurality of partitions are coaxially arranged.

[0009] As a further improvement of this utility model, the through hole is a cross hole.

[0010] As a further improvement of this utility model, the cable processing support fixture also includes a support frame, and a plurality of the partitions are detachably mounted on the support frame.

[0011] As a further improvement of this utility model, the support frame includes two side walls spaced apart, and the partition is inserted between the two side walls.

[0012] As a further improvement of this utility model, the support frame also includes an inlet plate at one end and an outlet plate at the other end of the support frame. The inlet plate and the outlet plate are both fixedly connected to the side wall. The inlet plate is provided with an inlet hole, and the outlet plate is provided with an outlet hole. The size of the inlet hole and the outlet hole is larger than the size of the through hole.

[0013] As a further improvement of this utility model, the through hole gradually decreases in size from the inlet hole toward the outlet hole.

[0014] As a further improvement of this utility model, the support frame also includes a bottom wall connected to the bottom of the side wall, and the partition is located above the bottom wall.

[0015] As a further improvement of this utility model, the sidewalls and the bottom wall are made of transparent material.

[0016] As a further improvement of this utility model, the partition is made of felt.

[0017] The beneficial effects of this utility model are: the cable processing support fixture of this utility model, by setting a partition with gradually narrowing through holes, forms a progressive radial smoothing of the cable, which fundamentally solves the problem of sheath breakdown caused by broken braided strands, while avoiding the slub and bamboo-like phenomena caused by traditional methods, and does not affect the product's appearance and structural consistency.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figures 1 to 2 As shown, the cable processing support fixture 100 of this utility model includes a plurality of partitions 1 spaced apart in the horizontal direction. The partitions 1 are provided with through holes 12 for cables to pass through, and the through holes 12 on the partitions 1 gradually decrease in size from one side to the other side.

[0026] The braided shielding wire needs to pass through the through holes 12 on the partition 1 in sequence. In this embodiment, one end of the larger through hole 12 is the inlet end, and one end of the smaller through hole 12 is the outlet end. The size of the through holes 12 changes gradually from the inlet end to the outlet end. When the cable core, which has completed the braiding of the shielding wire and is about to be extruded into the outer sheath, enters from the large-diameter through hole 12 end and exits from the small-diameter through hole 12 end, its surface will pass through these gradually decreasing through holes 12 in sequence.

[0027] By using the gradually shrinking through-holes 12 to effectively smooth the surface of the cable core, broken wires that have been raised due to friction and wear in the braided shielding layer can be pressed down and straightened, thereby fundamentally preventing them from puncturing the insulation sheath material during the subsequent extrusion sheathing process and avoiding major quality hazards such as "water ingress and spark breakdown" in the product.

[0028] In this embodiment, the external force applied to the cable is a radial, uniform smoothing force, rather than a binding tightening force. Therefore, it will not cause the braided metal wires to shift or accumulate, resulting in a "slub" phenomenon. Furthermore, the cable processing support fixture 100 is a fixing device, in which the cable passes smoothly without applying unstable longitudinal tension to the cable, thereby effectively eliminating the formation of slub-like structures.

[0029] The through hole 12 is a circular hole, and multiple through holes 12 on the partition plate 1 are coaxially arranged. For circular cables with stable diameter and high roundness, the circular hole can provide the best and most uniform smoothing effect. When the maximum smoothing force is required to deal with serious wire breakage and warping problems, the full contact method of the circular hole is more effective.

[0030] The through hole 12 is a cross-shaped hole. For cables with a larger outer diameter or a slight ellipticity, the cross-shaped hole can better adapt and avoid excessive resistance caused by uneven contact. When the cable itself cannot withstand a large frictional force, the low frictional force characteristic of the cross-shaped hole is an advantage.

[0031] The cable processing support fixture 100 also includes a support frame 2, on which multiple partitions 1 are detachably mounted. In this embodiment, the partitions 1 are made detachable, allowing for the selection of partitions 1 with different apertures for cables of different sizes, thus improving adaptability. Furthermore, the number and arrangement order of the partitions 1 can be flexibly adjusted, meaning more slots can be provided on the support to accommodate different numbers of partitions 1. Additionally, any worn partition 1 can be replaced individually, resulting in lower costs.

[0032] In this embodiment, the support frame 2 includes two spaced-apart side walls 21, with the partition 1 inserted between the two side walls 21. This configuration modularizes the core functions of the cable processing support fixture 100, making the installation, replacement, and spacing adjustment of the partition 1 exceptionally convenient. This greatly improves the equipment's adaptability to cables of different specifications, the efficiency of daily maintenance, and the flexibility of process debugging. Simultaneously, the structure itself is robust, reliable, and easy to manufacture, significantly reducing production and maintenance costs while achieving high efficiency.

[0033] The support frame 2 also includes an inlet plate 22 at one end and an outlet plate 23 at the other end. The inlet plate 22 and the outlet plate 23 are both fixedly connected to the side wall 21. The inlet plate 22 is provided with an inlet hole 221 and the outlet plate 23 is provided with an outlet hole 231. The size of the inlet hole 221 and the outlet hole 231 is larger than the size of the through hole 12.

[0034] The fixed inlet hole 221 and outlet hole 231 at both ends ensure the versatility and stability of the cable processing support fixture 100 when docking with the production line, as well as its initial guiding and protective function for the cables. Meanwhile, the detachable and replaceable gradient partition 1 in the middle provides the cable processing support fixture 100 with extreme flexibility and adaptability to cables of different diameters. The relatively large inlet hole 221 and outlet hole 231 allow the cable processing support fixture 100 to be compatible with most cables.

[0035] More specifically, the through hole 12 gradually decreases in size from the inlet hole 221 toward the outlet hole 231.

[0036] The support frame 2 also includes a bottom wall 24 connected to the bottom of the side wall 21, and the partition 1 is located above the bottom wall 24. In this embodiment, only the bottom wall 24 is provided and no top wall is provided, which facilitates inspection during the production process.

[0037] The sidewalls 21 and the bottom wall 24 are made of transparent material, which facilitates inspection during the production process.

[0038] The partition 1 is made of felt, which has excellent cushioning and protection, anti-slip and wear-resistant properties, and is environmentally friendly and recyclable. Of course, in addition to felt, cotton cloth or other highly wear-resistant and elastic materials can also be used as substitutes in other embodiments.

[0039] The cable processing support fixture 100 of this utility model, through the setting of a gradually narrowing partition 1 with through holes 12, forms a progressive radial smoothing of the cable, fundamentally solving the problem of sheath breakdown caused by broken braided strands. At the same time, it avoids the snagging and bamboo-like phenomena caused by traditional methods, and does not affect the product's appearance and structural consistency. Its modular design gives the fixture strong adaptability, easy maintenance and low cost advantages, while the open and transparent material structure ensures the visualization and convenience of operation, ultimately improving the consistency of cable quality while significantly reducing production costs.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
