Fig. 1 is a schematic view of a radial cut of a cable according to an embodiment of the invention.

Referring to fig. 1, the cable 100 includes a cable body 110 and a fiber braid 120, the fiber braid 120 being wrapped around the cable body 110. The cable main body 110 includes a plurality of core wires 112 and an outer coating layer 111 coated outside the plurality of core wires 112. The fiber braid 120 is formed by winding a plurality of filaments 300 around the outer cover 111 in a predetermined manner. The fiber braid 120 can provide good protection to the cable body 110, and can improve the overall strength of the cable 100 and the softness of the cable 100.

The filaments 300 used to weave the fibrous braid 120 may be selected from a corresponding material as desired for the performance of the cable 100. For example, when it is desired that cable 100 have certain fire-resistant characteristics, filament 300 may be made of a fire-resistant material; for another example, when good heat insulating properties are desired, the filament 300 may be made of a material having good heat insulating properties. The fibrous braid 120 may be woven from one or more filaments 300, as desired. In this embodiment, the fiber braid 120 may be woven using a plurality of polyethylene terephthalate (PET) filaments 300, which can provide the fiber braid 120 with good electrical insulation, fatigue resistance, and abrasion resistance.

In one comparative version related to an embodiment of the present invention, a plurality of filaments 300 are wrapped directly around the outer cover 111 to form the fibrous braid 120. Since the fiber filaments 300 are applied with a certain tension during the winding braiding, the braided fiber braid 120 may have a certain internal stress. When the cable 100 is split, the fiber braid 120 is cut and then retracted due to the internal stress of the fiber braid 120, so that the cross section of the cable body 110 and the cross section of the braid cannot be aligned, which adversely affects the use and subsequent processing of the cable 100.

Fig. 1 is a schematic view of a radial cross section of the cable of this embodiment at the adhesive section. Referring to fig. 1, in the present embodiment, an adhesive section 110a is disposed on an outer cover 111, and an adhesive 113 is coated on the adhesive section 110 a. When the filament 300 is wound around the viscose section 110a, the filament 300 is bonded with the adhesive 113. Accordingly, the fiber braid 120 formed by winding the fiber filaments 300 is bonded to the outer cover 111 by the adhesive 113, and thus, a good fixing effect can be provided to the fiber braid 120. The type of the adhesive 113 may be selected according to the amount of internal stress of the fiber braid 120, so as to ensure that the fiber braid 120 is not loosened due to the shrinkage internal stress of the fiber braid 120 after being bonded to the cable body 110 by the adhesive 113. When a certain length of the cable 100 is required to be taken, the cable 100 can be cut from the portion with the adhesive section 110a, and the fiber braid 120 at the cut is adhered and fixed with the outer cover 111, so that the fiber braid 120 cannot be loosened or retracted.

The cable 100 in the embodiment of the present invention may be an optical cable, an electrical cable, or other types of cables 100 for connecting devices or transmitting signals and energy, and the cable 100 is taken as an example for illustration in this embodiment. Further, the cable 100 in the embodiment of the present invention may be applied to a power line or a data line for manufacturing electronic devices (such as a mobile phone, a tablet computer, a notebook computer, etc.). Taking manufacturing a data line as an example, the cable 100 needs to be divided into cable segments with a certain length, and then the connector is connected with the notch of the cable segment in a riveting mode; by arranging the adhesive section 110a and dividing the cable 100 from the adhesive section 110a, the fiber woven layer 120 at the cut can be prevented from shrinking, so that the connector can be firmly connected with the fiber woven layer 120, the quality of a data line and the safety in the use process are ensured, and the fiber woven layer 120 is prevented from loosening in the use process.

The adhesive 113 at the adhesive segment 110a may be disposed around the surface of the outer cover 111, or may cover a partial area of the outer cover 111 in the circumferential direction (e.g., disposed in a semi-ring shape, a multi-dot shape, etc. in the circumferential direction of the outer cover 111. The length and position of the adhesive segment 110a may be set as desired.

Fig. 2 and 3 illustrate two different arrangements of adhesive segments of a cable according to an embodiment of the present invention.

Referring to fig. 2, in one possible embodiment, the length of the adhesive section 110a may be equal to the length of the cable body 110, i.e., the adhesive 113 is provided over the entire length of the cable body 110. After the cable 100 is divided at any position, the fiber braid 120 at the notch is fixedly connected with the cable body 110 through the adhesive 113, so that the cable 100 can be divided and taken at any position conveniently, and the overall strength of the cable 100 is enhanced.

Referring to fig. 3, in another possible embodiment, the cable 100 has a plurality of adhesive segments 110a with a predetermined spacing between adjacent adhesive segments 110a, such as 20cm, 50cm, 100cm, etc. When a certain length of the cable 100 needs to be taken, the fiber braid 120 at the cut can be separated at the corresponding adhesive section 110a, and the fiber braid 120 is adhered to the cable main body 110 by the adhesive 113, so that the fiber braid 120 can be prevented from shrinking. The manner of applying the adhesive 113 at intervals can save the adhesive 113 and ensure good flexibility of the cable 100. Further, the fibrous braid 120 also has indicia positioned to correspond to the location of at least a portion of the plurality of adhesive segments 110 a. By setting the mark, the position of the adhesive section 110a can be easily identified, and the cable 100 can be easily and accurately cut at the position of the adhesive section 110 a. The form of the mark may be arbitrarily selected as required, and for example, a symbol mark, a pattern mark, a dye mark, or the like may be provided.

The type and number of cores 112 is selected based on the particular type of use of the cable 100. The outer coating 111 serves to protect the core wire 112 from damage to the inner core wire 112. The material of the outer coating 111 may be selected according to the specific use needs of the cable 100. When the cable 100 is a cable, the outer coating 111 may be made of an insulating material. Further alternatively, the outer cover 111 may be made of a soft insulating material, such as silica gel, rubber, etc., so as to ensure a certain softness and flexibility of the cable 100, and facilitate the use of the cable 100.

Other structures, such as electromagnetic shielding layers, thermal insulation layers, etc., may also be provided between the outer jacket 111 and the core 112, depending on the use of the cable 100 and the properties to be achieved.

Referring to fig. 1, in some embodiments, the cable body 110 further has an electromagnetic shielding structure, which can reduce electromagnetic interference received during signal transmission of the cable 100. The electromagnetic shielding structure may be provided in the outer cover 111, and may be a single-layer structure or a multilayer structure. In one embodiment, the cable body 110 further includes a metallic shield layer and an outer shield layer 115. After the plurality of core wires 112 are arranged in a bundle in a predetermined manner, a metal shielding layer is wrapped around the outer circumferences of the plurality of core wires 112. The metal shield may be a metal film, a metal braid 114, or other form of metal shielding structure. In this embodiment, the metal shielding layer is a metal braid 114, and the metal braid 114 can improve the tensile performance of the cable 100 to a certain extent. An outer shielding layer 115 is disposed within the outer cover 111 and wrapped around the metal braid 114. The material of the outer shielding layer 115 may be selected based on the frequency of the electromagnetic interference signals that the cable 100 is desired to shield. The frequency range of the electromagnetic interference signal shielded by the outer shielding layer 115 may be different from the frequency of the electromagnetic interference signal shielded by the metal shielding layer, so that the frequency range of the electromagnetic shielding can be improved, and the signal transmission quality of the cable 100 can be improved. For example, the metal shielding layer may shield a high frequency signal, and the outer shielding layer 115 may be provided to shield an ultra high frequency signal.

In some embodiments, the cable body 110 may further include a plurality of ballistic resistant filaments 116, and the ballistic resistant filaments 116 may be filled between the metallic shield and the core 112, which may enhance the strength and tensile properties of the cable 100.

Embodiments of the present invention also provide a cable manufacturing apparatus that may be used to manufacture the cable 100 in at least some embodiments of the present invention.

Fig. 4 is a schematic perspective view of a cable manufacturing apparatus according to an embodiment of the present invention; fig. 5 and 6 are a front view and a top view, respectively, of an operating state when the cable manufacturing apparatus in the embodiment of the present invention manufactures a cable.

Referring to fig. 4-6, the cable manufacturing apparatus 200 includes a braiding device 230 and a take-up device 240. The braiding apparatus 230 is used to wind a plurality of filaments 300 around the cable body 110 in a predetermined manner to form the fibrous braid 120. The take-up device 240 is used for collecting the cable 100 after the fiber braid 120 is completed.

The take-up device 240 may take up any device that facilitates the collection of the cable 100. In the present embodiment, the wire takeup device 240 includes a spool and a spool driving device, and the rotational axis of the spool is disposed in a direction substantially perpendicular to the traveling direction of the cable 100. The drum driving device drives the drum to rotate so that the cable 100 is wound around the outer circumference of the drum. While collecting the cable 100, the take-up device 240 can also provide a certain tension to the cable, so that the braiding device 230 can perform the braiding operation of the fiber braid 120. Of course, the wire-rewinding device 240 may also collect the wires 100 in other manners, such as folding and stacking the wires 100.

Fig. 7 and 8 are schematic structural views of two different views of the gumming device and the braiding device according to the embodiment of the present invention.

Braiding apparatus 230 may take any configuration suitable for braiding fibrous braid 120. Referring to fig. 4-8, in some embodiments, knitting apparatus 230 includes a turntable 231 and a plurality of spindles 232 disposed on turntable 231. Spindle 232 is an important component on textile machinery, and can realize at least one of the functions of storing braided wires, controlling the winding and unwinding of the braided wires and adjusting the tension of the braided wires, and can realize the braiding action by the movement of spindle 232. The number and arrangement of the spindles 232 may be selected according to the designed structure of the fiber braid 120, for example, in this embodiment, the fiber braid 120 of the cable 100 is formed by braiding 36 fiber filaments 300, and the braiding apparatus 230 may correspondingly include 36 spindles 232. The particular configuration and dimensions of spindle 232 may be selected based on the dimensions of filament 300, the dimensions of cable 100, and the like.

The cable manufacturing apparatus 200 further includes a rack 210, and the braiding device 230 is disposed on the rack 210. The turntable 231 is rotatably disposed on the frame 210, and may be disposed on the frame 210 through a rotation shaft, for example. The turntable 231 has a central hole 231a, and the central hole 231a is located at a position corresponding to a rotation center of the turntable 231, and the central hole 231a is capable of allowing the cable body 110 to pass therethrough. A plurality of spindles 232 are disposed in the circumferential direction of the central hole 231a and are arranged according to the weave structure of the fiber weave layer 120.

The cable manufacturing apparatus 200 further comprises a glue application device 220, the glue application device 220 being adapted to apply the adhesive 113 to the outside of the cable body 110 to form the glue segment 110a. The position where the gluing device 220 is disposed may be determined according to the position of the braiding device 230 such that the filament 300 is not wound around the corresponding portion of the cable body 110 when the gluing device 220 is coated with the adhesive 113 outside the cable body 110; in a short time after the cable main body 110 is coated with the adhesive 113, the braiding apparatus 230 can wind the fiber filaments 300 outside the corresponding viscose section 110a to form the fiber braiding layer 120, so that the braided fiber braiding layer 120 is bonded with the viscose section 110a, and the adhesive 113 is prevented from being cured or volatilized when the fiber filaments 300 are not wound after being coated, thereby affecting the bonding effect.

The gluing means 220 may be a painting, dispensing, spraying or other means, and the specific type of the gluing means 220 may be selected according to the diameter of the cable 100, the structure of the braiding apparatus 230, etc. For example, when the turntable 231 of the knitting device 230 is small in size and the glue applicator 220 is located close to the drawn filament 300, the glue applicator 220 may apply glue by painting, dispensing, or the like, to prevent the adhesive 113 from splashing onto the filament 300 and affecting the normal knitting of the fiber knit layer 120.

In some embodiments, the glue applicator 220 is secured to the turntable 231. The gluing device 220 includes a gluing unit 220A, and the gluing unit 220A is disposed in the circumferential direction of the central hole 231 a. The number of the glue applying units 220A may be one or more, and the specific number of the glue applying units 220A may be selected according to the diameter of the cable main body 110, the glue applying position, etc. For example, referring to fig. 7 and 8, in the present embodiment, the number of the glue applying units 220A is two, and the two glue applying units 220A are disposed opposite to each other, and glue is applied to the cable main body 110 circumferentially from both directions so that the adhesive 113 can cover substantially the entire surface of the cable main body 110.

The glue spreading unit 220A includes a glue delivery tube 221 and a glue brush 222. The glue delivery tube 221 is used for supplying the adhesive 113, and the glue brush 222 is connected with the glue delivery tube 221 for applying the adhesive 113 to the outer surface of the cable body 110. The glue brush 222 may be made of a soft material to prevent the glue brush 222 from damaging the cable body 110 during gluing, for example, the glue brush 222 may be made of a sponge, a silicone, a rubber, or the like. The shape and size of the glue brush 222 are adapted to the shape and size of the outer surface of the cable body 110 so that the glue brush 222 can uniformly spread the adhesive 113 on the surface of the cable body 110.

When it is desired to perform an intermittent gluing operation (i.e. such that there is a certain spacing between adjacent glue segments 110a on the cable body 110), the gluing unit may further comprise a glue brush driving means 223. The glue brush driving device 223 is used for driving the glue brush 222 to move so that the glue brush 222 can be close to the cable main body 110 to apply the adhesive 113, and can be far away from the surface of the cable main body 110 to enable a certain interval between two adjacent glue sections 110 a. The driving device 223 of the glue brush can select a driving device with a proper type and model according to the requirement of driving control of the glue brush 222, and in this embodiment, the driving device 223 of the glue brush is an air cylinder, so that the position of the glue brush 222 can be controlled well.

Fig. 9 and 10 are a schematic perspective view and a top view of a marking device according to an embodiment of the present invention; fig. 11 is a cross-sectional view of the marking device of the embodiment of the present invention taken along the plane C-C in fig. 10.

In some embodiments, referring to fig. 4-6 and 9-11, the cable manufacturing apparatus 200 further includes a marking device 250 for providing a marking on the cable 100. Marking device 250 may be disposed between knitting device 230 and take-up device 240. After the braiding apparatus 230 has completed braiding the fiber braid 120, the marking apparatus 250 places a mark on the cable 100 before the cable 100 is collected by the take-up apparatus 240. The positions of the marks correspond to at least part of the adhesive segments 110a on the cable 100, and the marks are set by the marking device 250, so that the adhesive segments 110a on the cable 100 can be conveniently identified, and the adhesive segments 110a can be conveniently and accurately cut when the cable 100 is cut later.

The marking device 250 may be selected according to the type of marking to be placed on the cable 100. The marking device 250 may be a dye spraying device, a stamping device, a hot pressing device, or the like. In an alternative embodiment, marking device 250 includes two marking jaws 251 that are disposed opposite one another. The marking claws 251 have a pressing end 251a for placing a mark in contact with the cable 100, and the pressing ends 251a of the two marking claws 251 may be pressed in contact with the cable 100 to form a mark on the surface of the cable 100 while the cable 100 is traveling. The marking device 250 further comprises a marking driving device 252 for driving the two marking claws 251 to move relatively, i.e. the marking driving device 252 is capable of driving the two marking claws 251 to move towards each other to clamp the cable 100 for marking, and driving the two marking claws 251 away from each other to release the cable 100. In this embodiment, the marking driving device 252 may be a pneumatic clamping jaw, so that the synchronization of the movements of the two marking claws 251 can be better controlled. Further, the marking device 250 may set the mark by hot pressing, and the marking device 250 further includes a heating assembly 253 for heating the marking claw 251. The heating assembly 253 heats the marking jaw 251 such that when the marking jaw 251 is in contact with the fiber braid 120, the marking jaw 251 having a relatively high temperature is capable of softening the fiber braid 120 to facilitate imprinting of the mark on the fiber braid 120. The heating assembly 253 may include a heating element such as a ceramic heater, a heating wire, etc., and heat the marking jaw 251 by heat conduction, heat radiation, etc. For example, the heating assembly 253 in the present embodiment includes a heating rod.

In some embodiments, referring to fig. 9-11, the marking device 250 includes a mounting block 254 and two sliders 255, with two marking fingers 251 mounted on corresponding sliders 255. The mounting block 254 has a guide groove 254a, and two sliders 255 are provided in the guide groove 254a and are movable along the guide groove 254a so that the two marking claws 251 can move in the extending direction of the guide groove 254 a. Alternatively, the extending direction of the guide groove 254a is substantially perpendicular to the traveling direction of the cable 100, so that the two marking claws 251 can approach and depart from the cable 100 from the side of the cable 100. Optionally, the marking device 250 further includes an elastic member 256, where the elastic member 256 elastically supports the two sliders 255, so as to prevent the cable 100 from being damaged due to excessive clamping force of the two marking claws 251. The elastic member 256 may select a suitable member according to the need for buffering the marking claw 251, and for example, a spring, a rubber block, an elastic band, a damper, or the like may be selected. In the present embodiment, referring to fig. 11, the elastic member 256 is a spring, and the elastic member 256 is disposed between two sliders 255.

Fig. 12 is a schematic diagram of the working principle of the marking device according to the embodiment of the present invention.

To improve the working efficiency, the travel of the cable 100 is prevented from being affected in the process of setting the mark, and in some embodiments, the marking claw 251 can rotate. Referring to fig. 9 to 12, in one embodiment, the marking claw 251 is rotatably coupled to the slider 255, for example, by a rotation shaft which is substantially perpendicular to the traveling direction of the cable 100 and the extending direction of the guide groove 254 a. The marking claw 251 grips the cable 100, and when the cable 100 continues to travel, the marking claw 251 can roll on the surface of the cable 100 so as not to affect the travel of the cable 100, and at the same time, can form a mark having a certain length on the surface of the cable 100.

In some embodiments, the mounting block 254 further has a reset guide surface 254b, and the marking pawl 251 has a guide end 251b, the guide end 251b being disposed opposite the reset guide surface 254 b. The reset guide surface 254b cooperates with the guide end 251b to assist in rotationally resetting the marking pawl 251. In one embodiment, referring to fig. 9-12, the guide end 251b may be disposed opposite the stamping end 251a, i.e., the guide end 251b and the stamping end 251a are disposed at opposite ends of the marking jaw 251, respectively. The reset guide surface 254b may be an inclined surface and inclined to the traveling direction of the cable 100, and an angle between the reset guide surface 254b and the traveling direction of the cable 100 is designed according to a movement track of the guide end 251b during operation. In this embodiment, the reset guide surface 254b has a first end and a second end, and the first end of the reset guide surface 254b is spaced from the cable 100 more than the second end. In contrast to the two upper drawings in fig. 12, the marking driving device 252 drives the two marking claws 251 to move relatively so that the stamping ends 251a of the two marking claws 251 clamp the cable 100. In contrast to the two right-hand drawings in fig. 12, when the wire winding device 240 drives the cable 100 to move, the cable 100 drives the marking claw 251 to rotate relative to the slider 255 along the direction r1 in the drawing, and the guide end 251b moves along the reset guide surface 254b from the first end to the second end of the reset guide surface 254 b. When the marking is completed, the marking driving device 252 drives the two marking claws 251 to move away from each other, and the guide end 251b abuts against the reset guide surface 254b and moves along the reset guide surface 254b under the action of the driving force, so that the second end of the reset guide surface 254b moves to the first end, and in this process, the marking claws 251 rotate in the direction r2 in the figure to reset, and finally return to the state of the upper left corner in the figure.

In some embodiments, the cable manufacturing apparatus 200 further includes a splitting device (not shown) for splitting the cable 100 to split the longer cable 100 into shorter cable segments. In this embodiment, the splitting device may be used to split the cable 100 at the markers. In one embodiment, the dividing means has a marker identifier for identifying the marker, and the dividing means divides the cable 100 when the marker is identified. In another embodiment, the segmenting means is aligned with the markers first, and then the cable 100 is segmented after the segmenting means has traveled the cable 100 a predetermined length according to the length of the space between adjacent markers, such that the location of the segment substantially coincides with the location of the next marker.

It should be understood that the cable manufacturing device 200 of the present embodiment may be used, but is not limited to, for manufacturing the cable 100 described in the present embodiment. The cable manufacturing apparatus 200 may also be used to manufacture other kinds of cables. For example, when it is not necessary to apply the adhesive 113 to the cable body 110, the adhesive applying device 220 may be stopped, whereby a cable having no adhesive section may be manufactured.

Embodiments of the present invention also provide a cable manufacturing method that may be used to manufacture the cable 100 in at least some embodiments of the present invention.

Fig. 13 is a schematic flow chart of a cable manufacturing method according to an embodiment of the invention.

Referring to fig. 13, the cable manufacturing method according to the embodiment of the present invention includes the following steps S410 to S430:

step S410, providing a cable body.

Referring to fig. 1 and the related description of fig. 1 above, the cable body 110 includes a plurality of core wires 112 and an outer coating 111. The plurality of core wires 112 may be arranged and integrated into a bundle in a predetermined manner, and then other layers of the cable body 110 may be formed on the plurality of core wires 112 by extrusion molding, sleeving, or the like, and finally the outer coating layer 111 may be disposed on the outermost layer to wrap the plurality of core wires 112. The manner of manufacturing the cable body 110 may be selected accordingly according to the specific structure of the cable body 110.

Fig. 14 is a flow chart of a method for providing a cable body according to an embodiment of the present invention.

In one scenario, the cable body 110 further includes the metal braid 114 and the outer shield 115 shown in fig. 1 and described in the foregoing description of fig. 1. Then, as shown in fig. 14, step S410 may include steps S411 to S413 as follows:

Step S411, forming a metal braid outside the plurality of core wires.

The metal braid 114 may be formed by wrapping a metal braid around the plurality of core wires 112, or by winding a plurality of metal wires around the plurality of core wires 112, or by other means. Those skilled in the art may select a suitable manufacturing method for forming the metal braid 114 according to production needs.

And step S412, forming an outer shielding layer outside the metal braiding layer.

The manner of forming the outer shield layer 115 may be selected according to the material characteristics of the outer shield layer 115. For example, when the outer shielding layer 115 is a thermoplastic polymer, the outer shielding layer 115 may be formed outside the metal braid by extrusion, thermal shrinkage, thermal spraying, or the like.

Step S413, forming an outer cover layer outside the outer shielding layer.

The manner of forming the outer coating 111 is selected according to the material characteristics of the outer coating 111. For example, in the present embodiment, the outer cover 111 may heat the silicone heat shrinkage tube by a heating device, so that the silicone heat shrinkage tube is shrink-sleeved around the outer shielding layer 115.

And S420, coating an adhesive on the outer side of the cable main body to form an adhesive section.

According to the actual production conditions such as production scale, the adhesive 113 can be coated on the outer surface of the cable body 110 to form the adhesive section 110a by manual or automatic mechanical methods. The adhesive 113 may be provided over the entire length of the cable main body 110, or may be provided at intervals in the length direction of the cable main body 110.

Step S430, winding a plurality of fiber filaments outside the cable body to form a fiber braid.

Depending on the actual production conditions such as the production scale, the fiber braiding layer 120 may be formed by winding the plurality of filaments 300 around the cable main body 110 in a predetermined manner by hand braiding, man-machine braiding, or automated mechanical braiding. During braiding of the fibrous braid 120, at least a portion of the filaments 300 cover the adhesive segment 110a to bond the braided fibrous braid 120 to the cable body 110.

In an application scenario, in large-scale cable production, the cable manufacturing process may be performed in a semi-automatic or fully-automatic mechanical manner, so as to improve production efficiency. In this scenario, further adjustments may be made to the cable manufacturing method shown in fig. 13. Referring to fig. 15, step S420 may be embodied as step S420A as follows, and step S430 may be embodied as step S430A as follows:

In step S420A, an adhesive is coated on the outer side of the cable body by a glue coating device to form a glue section.

The specific form of the glue applicator can be selected according to the requirements of actual production conditions, and the glue applicator can be coated with the adhesive 113 by spraying, smearing, dispensing and the like. Taking the glue application device 220 shown in fig. 4-8 and described in the foregoing related description as an example, in one embodiment, the glue application device 220 applies the adhesive 113 to the exterior of the cable body 110 at a predetermined frequency such that there is a certain spacing between adjacent glue segments 110 a.

Further, in order to increase the automation level of the production, the glue application device 220 may perform a corresponding action according to the interval size of the glue sections 110a to achieve the interval automatic glue application. Assuming that the interval between two adjacent adhesive segments 110a is L and the traveling speed of the cable is v, the time interval t for the adhesive applying device 220 to perform the adhesive applying operation may be L/v. In an alternative embodiment, the glue applicator 220 includes a glue brush 222, and the glue applicator 220 drives the glue brush 222 to move at a predetermined frequency to apply the adhesive 113 to the exterior of the cable body 110. In another alternative embodiment, the glue applicator includes a glue gun and applies the adhesive 113 by spraying, and the glue applicator drives the glue gun at a predetermined frequency to spray the adhesive 113 outside the cable body 110. In the two foregoing embodiments, the predetermined frequency corresponds to the foregoing time interval t.

Step S430A, winding a plurality of fiber filaments outside the cable body by a braiding device to form a fiber braid.

Braiding apparatus 230 may be of a type suitable for use as desired for production. Taking the braiding apparatus 230 as shown in fig. 4-8 and described in the foregoing related description as an example, the braiding apparatus 230 drives the turntable 231 and the plurality of spindles 232 to rotate according to a predetermined rule, and winds the plurality of filaments 300 around the cable main body 110 to form the fibrous braid 120 having a certain shape.

In some embodiments, step S430A may further include the following step S440A:

step S440A, a marking is set on the cable by a marking device.

According to the subsequent processing and using requirements of the cable, marks are arranged at the corresponding positions of the fiber braid 120 of the cable through a marking device so as to play a role in facilitating identification. Taking the marking device 250 shown in fig. 4-6 and 9-12 and described in the foregoing related description as an example, the marking device 250 may be disposed close to the braiding device 230, and the braided cable may be conveyed to the marking device 250 to set a mark. In one embodiment, the location of the indicia corresponds to the location of at least a portion of the section of adhesive 110a, such that the location of the section of adhesive 110a can be readily identified. In the case where the adhesive 113 is applied to the outside of the cable body 110 by the adhesive applying device 220 at a predetermined frequency and the traveling speed of the cable is maintained constant, the marking device 250 may perform a corresponding action at a corresponding frequency and set a mark on the cable. Thus, a better correspondence of the position of the marking with the position of the adhesive segment 110a can be achieved.

In some application scenarios, further processing of the longer cable into a plurality of shorter cable segments is required. For example, in manufacturing a data line, it is necessary to divide a cable into cable segments of a predetermined length and then attach connectors to the cut portions of the cable segments by crimping or the like. In this scenario, step S450A may be further included after step S440A as follows:

step S450A, dividing the cable at the mark by dividing means.

The splitting means may comprise a cutter for splitting the cable. When the cable is split, a certain traction device can be adopted to draw one end of the cable to move. After the dividing device divides the cable at one mark, the traction device pulls the cable to move by a corresponding distance L so that the next mark moves to the cutter.

It will be appreciated that not all of the steps described above need be strictly followed during the actual cable manufacturing process. Some of the above steps (e.g., step S450A is omitted), or a new step (e.g., a step of performing other processing on the cable between step S440A and step S450A) is added, etc., as needed for actual production.

The cable manufacturing method in the embodiment of the invention can be applied to control of the cable manufacturing device in at least some embodiments of the invention, that is, the cable manufacturing device in at least some embodiments of the invention can realize the cable manufacturing method in the embodiment of the invention. Of course, those skilled in the art may also use other devices, apparatuses, etc. to implement the cable manufacturing method according to the embodiments of the present invention according to the actual situation.
