FIG. 1 is a schematic view of a radial cross-section of a cable according to an embodiment of the invention.

Referring to fig. 1, the cable 100 includes a cable main body 110 and a fiber braid 120, and the fiber braid 120 is wrapped outside the cable main body 110. The cable main body 110 includes a plurality of core wires 112, and a jacket layer 111 that wraps outside the plurality of core wires 112. The fiber weaving layer 120 is formed by winding a plurality of fiber filaments 300 around the outer layer 111 in a predetermined manner. The fiber braided layer 120 can protect the cable main body 110 well, improve the overall strength of the cable 100, and improve the flexibility of the cable 100.

The fiber filaments 300 used to weave the fiber braid 120 may be selected according to the requirements for the performance of the cable 100. For example, when the cable 100 is required to have certain fire-resistant properties, the fiber filaments 300 may be made of a fire-resistant material; for example, when a good heat insulating property is required, a material having a good heat insulating property may be used for the fiber 300. The woven fiber layer 120 may be woven using one or more fiber filaments 300, as desired. In this embodiment, the fiber-woven layer 120 may be formed by weaving a plurality of polyethylene terephthalate (PET) filaments 300, and the fiber-woven layer 120 may have excellent electrical insulation, fatigue resistance, and friction resistance.

In one comparative approach relating to embodiments of the present invention, a plurality of filaments 300 are wound directly around the outer layer 111 to form the woven fiber layer 120. Since the fiber 300 is applied with a certain tension during the winding and weaving process, the woven fiber woven layer 120 having a completed weaving process may have a certain internal stress. When the cable 100 is cut, due to the internal stress of the fiber braid 120, the fiber braid 120 may be shrunk after being cut, so that the cross section of the cable body 110 and the cross section of the braid may not be aligned, which may adversely affect the use and subsequent processing of the cable 100.

Fig. 1 is a schematic view of a radial cut-out of the cable of this embodiment at the adhesive segment. Referring to fig. 1, in the present embodiment, an adhesive section 110a is disposed on the outer layer 111, and an adhesive 113 is disposed on the adhesive section 110 a. When the filament 300 is wound on the viscose section 110a, the filament 300 is bonded with the adhesive 113. Accordingly, the woven fiber layer 120 formed by winding the fiber yarn 300 is bonded to the outer layer 111 with the adhesive 113, and the woven fiber layer 120 can be fixed well. The kind of the adhesive 113 may be selected according to the magnitude of the internal stress of the fiber braid 120, so as to ensure that the fiber braid 120 is not loosened due to the internal stress of the fiber braid 120 after being bonded to the cable main body 110 by the adhesive 113. When a certain length of the cable 100 needs to be taken, the cable 100 can be cut from the portion having the adhesive section 110a, and the woven fiber layer 120 is not loosened or retracted because the woven fiber layer 120 at the cut is adhered and fixed to the outer layer 111.

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 present embodiment takes the cable 100 as an example for description. Further, the cable 100 in the embodiment of the present invention may be applied to manufacture a power line or a data line of an electronic device (e.g., a mobile phone, a tablet computer, a notebook computer, etc.). Taking manufacturing of 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 notches of the cable segments by riveting or the like; through setting up viscose section 110a and cutting apart cable 100 from viscose section 110a, can prevent that the fibre weaving layer 120 of incision department from shrinking back, make the connector can firmly realize being connected with fibre weaving layer 120, guarantee the quality of data line and the security in the use, prevent that fibre weaving layer 120 from taking off in the use pine.

The adhesive 113 at the adhesive segment 110a may be disposed around the surface of the outer layer 111, or may cover a partial region of the outer layer 111 in the circumferential direction (e.g., disposed in a semi-annular, multi-point manner, etc. in the circumferential direction of the outer layer 111, the length and the position of the adhesive segment 110a may be set as required.

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

Referring to fig. 2, in one possible embodiment, the length of the adhesive segment 110a may be equal to the length of the cable body 110, i.e., the entire length of the cable body 110 is provided with the adhesive 113. After the cable 100 is cut at any position, the fiber braid layer 120 at the cut is fixedly connected with the cable main body 110 through the adhesive 113, so that the cable 100 can be conveniently cut at any position and taken, 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, and so forth. When the cable 100 with a certain length needs to be taken, the corresponding adhesive section 110a can be divided, and the fiber woven layer 120 at the notch is bonded with the cable main body 110 through the adhesive 113, so that the fiber woven layer 120 can be prevented from being retracted. The adhesive 113 can be saved by coating the adhesive 113 at intervals, and the cable 100 can have better flexibility. Further, the fiber woven layer 120 also has markings, the positions of which correspond to the positions of at least a portion of the plurality of adhesive sections 110 a. By providing the mark, the position of the adhesive segment 110a can be easily identified, and the cable 100 can be easily and accurately segmented at the position of the adhesive segment 110 a. The form of the mark can be arbitrarily selected according to the need, and for example, it can be provided as a symbol mark, a pattern mark, a dyed mark, or the like.

The type and number of cords 112 are selected based on the particular type of use of cable 100. The outer layer 111 protects the core wires 112 and prevents the core wires 112 inside from being damaged. The material of the outer layer 111 may be selected according to the specific use requirements of the cable 100. When the cable 100 is an electric cable, the outer layer 111 may be made of an insulating material. Further optionally, the outer layer 111 may be made of a soft insulating material, such as silica gel, rubber, and the like, so that the cable 100 may have certain softness and flexibility, and the cable 100 may be conveniently used.

Other structures, such as electromagnetic shielding layers, thermal insulating layers, etc., may also be provided between the outer layer 111 and the core 112 depending on the application and the desired performance of the cable 100.

Referring to fig. 1, in some embodiments, the cable body 110 further has an electromagnetic shielding structure, which can reduce electromagnetic interference to the cable 100 during signal transmission. The electromagnetic shielding structure may be disposed within the outer layer 111, and may be a single layer structure or a multi-layer structure. In one embodiment, the cable body 110 further includes a metallic shield layer and an outer shield layer 115. The plurality of core wires 112 are arranged in a bundle according to a predetermined manner, and the metal shielding layer is wrapped around the outer circumference of the plurality of core wires 112. The metallic shielding layer may be a metallic film, a metallic braid 114, or other form of metallic shielding structure. In this embodiment, the metal shielding layer is a metal braid 114, and the metal braid 114 can improve the tensile strength of the cable 100 to some extent. The outer shield layer 115 is disposed within the outer layer 111 and is wrapped around the metal braid 114. The material of the outer shielding layer 115 may be selected according to 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 may be increased, and the signal transmission quality of the cable 100 may be improved. For example, a metal shield may shield high frequency signals and the outer shield 115 may be configured to shield ultra high frequency signals.

In some embodiments, the cable body 110 may further include a plurality of anti-bullet wires 116, and the anti-bullet wires 116 may be filled between the metal shielding layer and the core wires 112, which can enhance the strength and tensile strength of the cable 100.

Embodiments of the present invention also provide a cable manufacturing apparatus, which 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 plan view, respectively, of an operating state in which 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 device 230 is used for winding a plurality of filaments 300 outside the cable main body 110 in a predetermined manner to form the fiber braid 120. The take-up device 240 is used to collect the cable 100 after the fiber braid 120 is completed.

The take-up device 240 may employ any device that facilitates 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 arranged in a direction substantially perpendicular to the traveling direction of the wire 100. The drum driving device drives the drum to rotate, so that the wire 100 is wound around the outer circumference of the drum. While collecting the cable 100, the take-up device 240 may provide a certain tension to the cable, so as to facilitate the braiding operation of the fiber braid 120 by the braiding device 240. Of course, the wire takeup device 240 may collect the cables 100 in other ways, such as in a folded and stacked manner.

Fig. 7 and 8 are schematic structural diagrams of a gluing device and a weaving device at two different viewing angles according to an embodiment of the invention.

Braiding apparatus 230 may take any configuration suitable for braiding fiber braid 120. Referring to fig. 4-8, in some embodiments, the braiding apparatus 230 includes a turntable 231 and a plurality of spindles 232 disposed on the turntable 231. The spindle 232 is an important component on the textile machine, and can realize at least one of the functions of storing the braided wire, controlling the take-up and pay-off of the braided wire and adjusting the tension of the braided wire by alone or in cooperation with other mechanisms, and the braiding action can be realized through the movement of the spindle 232. The number and arrangement of the spindles 232 may be selected according to the designed structure of the fiber braiding layer 120, for example, in the embodiment, the fiber braiding layer 120 of the cable 100 is braided by 36 fiber filaments 300, and the braiding device 230 may correspondingly include 36 spindles 232. The specific configuration and size of spindle 232 may be selected based on the size of filament 300, the size of cable 100, and the like.

The cable manufacturing apparatus 200 further includes a frame 210, and a braiding device 230 is disposed on the frame 210. The turntable 231 is rotatably disposed on the frame 210, and may be disposed on the frame 210 through a rotating shaft, for example. The turntable 231 has a center hole 231a, the center hole 231a is located corresponding to the rotation center of the turntable 231, and the center hole 231a can be penetrated by the cable main body 110. A plurality of spindles 232 are disposed in the circumferential direction of the center hole 231a and are arranged according to the braiding structure of the fiber braiding 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 outside the cable body 110 to form the glue section 110 a. The position where the glue applying device 220 is disposed may be determined according to the position of the weaving device 230, so that the fiber filaments 300 are not wound around the corresponding portion of the cable body 110 when the glue applying device 220 applies the adhesive 113 on the outside of the cable body 110; in a short time after the adhesive 113 is coated on the cable main body 110, the weaving device 230 can wind the fiber yarn 300 around the corresponding viscose section 110a to form the fiber woven layer 120, so that the fiber woven layer 120 formed by weaving is bonded with the viscose section 110a, and the adhesive 113 is prevented from being solidified or volatilized when the fiber yarn 300 is not wound after being coated, and the bonding effect is prevented from being influenced.

The glue coating device 220 may be applied by coating, dispensing, spraying or other methods, and the specific type of the glue coating device 220 may be selected according to the diameter of the cable 100, the structure of the weaving device 230, etc. For example, when the size of the rotating disc 231 of the braiding apparatus 230 is small and the position of the glue applying apparatus 220 is close to the led-out filament 300, the glue applying apparatus 220 may apply glue by means of smearing, dispensing, etc. to prevent the adhesive 113 from splashing on the filament 300 to affect the normal braiding of the fiber braiding layer 120.

In some embodiments, the glue applicator 220 is fixed 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 center 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 body 110, the glue applying position, and the like. For example, referring to fig. 7 and 8, in the present embodiment, the number of the glue applying units 220A is two, two glue applying units 220A are disposed opposite to each other, and glue is applied to the circumference of the cable main body 110 from two directions, so that the adhesive 113 can cover substantially the entire surface of the cable main body 110.

The glue applying unit 220A includes a glue feeding tube 221 and a glue brush 222. The adhesive supply tube 221 supplies the adhesive 113, and the adhesive brush 222 is connected to the adhesive supply tube 221 to apply the adhesive 113 to the outer surface of the cable main 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 when applying glue, for example, the glue brush 222 may be made of sponge, silica gel, rubber, etc. 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 apply the adhesive 113 to the surface of the cable body 110.

When it is desired to perform a discontinuous glue application (i.e. to provide a certain spacing between adjacent glue segments 110a on the cable body 110), the glue application unit may further comprise a glue brush drive 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 glue brush driving device 223 can select a driving device with a suitable type and model according to the requirement of the driving control of the glue brush 222, and in this embodiment, the glue brush driving device 223 is an air cylinder, which can control the position of the glue brush 222 well.

Fig. 9 and 10 are a schematic perspective view and a top view, respectively, 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 placing a mark on the cable 100. The marking device 250 may be disposed between the braiding device 230 and the take-up device 240. After the braiding apparatus 230 has braided 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 240. The position of the mark corresponds to at least a part of the adhesive segment 110a on the cable 100, and the marking device 250 is used for setting the mark, so that the adhesive segment 110a on the cable 100 can be identified conveniently, and the subsequent cutting of the cable 100 can be conveniently and accurately performed at the adhesive segment 110 a.

The marking device 250 may be selected as desired for the type of marking to be placed on the cable 100. The marking device 250 may be a dye spray device, an embossing device, a hot press device, or the like. In an alternative embodiment, the marking device 250 includes two marking jaws 251 that are disposed opposite to each other. The marking claws 251 have a pressing end 251a for setting a mark in contact with the cable 100, and the pressing end 251a of the two marking claws 251 may be pressed in contact with the cable 100 while the cable 100 passes between the two marking claws 251 during traveling, thereby forming a mark on the surface of the cable 100. 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 can drive the two marking claws 251 to move towards each other to clamp the cable 100 for marking and drive the two marking claws 251 to move away from each other to release the cable 100. In this embodiment, the marking driving device 252 may be a pneumatic clamping jaw, which can better control the motion synchronization of the two marking jaws 251. Further, the marking device 250 may be configured to mark by using a hot pressing method, and the marking device 250 further includes a heating assembly 253 for heating the marking claw 251. The heating component 253 heats the marking claw 251, and when the marking claw 251 is in contact with the fiber woven layer 120, the marking claw 251 with higher temperature can soften the fiber woven layer 120, so as to facilitate the mark stamping on the fiber woven layer 120. The heating assembly 253 may include a ceramic heater, a heating wire, or other heating element, and may heat the marking claw 251 by thermal conduction, thermal radiation, or the like. For example, the heating assembly 253 in the present embodiment includes a heating rod.

In some embodiments, referring to FIGS. 9-11, the marking device 250 includes a mounting block 254 and two sliders 255 with two marking jaws 251 mounted on the respective sliders 255. The mounting block 254 has a guide groove 254a, and two sliders 255 are provided in the guide groove 254a and 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 separate from the cable 100 from the side of the cable 100. Optionally, the marking device 250 further comprises an elastic member 256, and the elastic member 256 elastically supports the two sliders 255 to prevent the cable 100 from being damaged due to excessive clamping force of the two marking claws 251. The elastic member 256 may be selected to have a suitable component according to the need for cushioning the marking claw 251, such as a spring, a rubber block, an elastic band, a damper, or the like. In the present embodiment, referring to fig. 11, the elastic member 256 is a spring, and the elastic member 256 is disposed between the two sliders 255.

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

To improve the working efficiency and avoid affecting the travel of the cable 100 during the marking process, the marking claw 251 can be rotated in some embodiments. Referring to fig. 9-12, in one embodiment, the marking jaw 251 is pivotally coupled to the slide 255, for example, via a pivot axis that is substantially perpendicular to the direction of travel of the cable 100 and the direction of extension of the guide slot 254 a. The marking claw 251 clamps the cable 100, and as the cable 100 continues to travel, the marking claw 251 can roll along the surface of the cable 100, thereby not affecting the travel of the cable 100, and simultaneously, marks with a certain length can be formed on the surface of the cable 100.

In some embodiments, the mounting block 254 further has a reset guide surface 254b, and the marking claw 251 has a guide end 251b, the guide end 251b being disposed opposite the reset guide surface 254 b. The reset guide surface 254b is engaged with the guide end 251b to assist in rotationally resetting the marking claw 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 stamping jaw 251. The reset guide surface 254b may be an inclined surface and inclined to the advancing direction of the cable 100, and an included angle between the reset guide surface 254b and the advancing direction of the cable 100 is designed according to a moving track of the guide end 251b during operation. In the present 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 by a distance greater than the second end is spaced from the cable 100. Referring 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. Referring to the two right-hand drawings of fig. 12, when the cable 100 is moved by the take-up device 240, the marking claw 251 is rotated by the cable 100 relative to the slider 255 in the direction r1, and the guide end 251b moves along the reset guide surface 254b and moves from the first end to the second end of the reset guide surface 254 b. Referring to the two lower drawings in fig. 12, when the marking is set, the marking driving device 252 drives the two marking claws 251 to move away from each other, and under the driving force, the guide end 251b abuts against the reset guide surface 254b and moves along the reset guide surface 254b, the second end of the self-reset guide surface 254b moves to the first end, and in the process, the marking claw 251 rotates in the direction r2 in the drawing to reset, and finally returns to the state of the upper left corner in the drawing.

In some embodiments, cable manufacturing apparatus 200 further includes a splitting device (not shown) for splitting cable 100 to split longer cable 100 into shorter cable segments. In this embodiment, a splitting device may be used to split the cable 100 at the mark. In one embodiment, the separation device has a mark identifier for identifying the mark, and the separation device separates the cable 100 when the mark is identified. In another embodiment, the separation device is aligned with the mark, and then the separation device is caused to separate the cable 100 after the cable 100 has traveled a predetermined length according to the length of the space between adjacent marks, such that the separation location substantially coincides with the position of the next mark.

It should be understood that the cable manufacturing apparatus 200 of the present embodiment may be, but is not limited to, used to manufacture 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 on the cable main body 110, the glue applying device 220 may be stopped, whereby a cable having no section of adhesive can be manufactured.

Embodiments of the present invention further provide a cable manufacturing method, which 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 method for manufacturing a cable according to the embodiment of the present invention includes steps S410 to S430 as follows:

and step S410, providing a cable main body.

Referring to fig. 1 and the foregoing description related to fig. 1, cable body 110 includes a plurality of core wires 112 and a jacket 111. The plurality of core wires 112 may be arranged and bundled in a predetermined manner, and then the other layers of the cable main body 110 may be formed outside the plurality of core wires 112 by extrusion molding, nesting, or the like, and finally the outer layer 111 is disposed at the outermost layer, wrapping 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 illustrating a method of providing a cable body according to an embodiment of the invention.

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

step S411, forming a metal braid layer 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 and braiding a plurality of metal wires around the plurality of core wires 112, or by other methods. One skilled in the art can 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 braided layer.

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

And step S413, forming an outer layer outside the outer shielding layer.

The formation manner of the outer layer 111 is selected according to the material characteristics of the outer layer 111. For example, in this embodiment, the outer layer 111 can be heated by a heating device to shrink the silicone heat-shrinkable tube around the outer shielding layer 115.

Step S420, coating an adhesive on the outside 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 outside of the cable main body 110 by manual or automatic machine to form the adhesive section 110 a. The adhesive 113 may be provided over the entire length of the cable main body 110, or may be provided at intervals in the longitudinal direction of the cable main body 110.

And S430, winding a plurality of fiber yarns outside the cable main body to form a fiber braided layer.

According to the actual production conditions such as production scale, a manual knitting mode, a manual mechanical knitting mode or an automatic mechanical knitting mode can be selected, and the plurality of fiber yarns 300 are wound outside the cable main body 110 according to a certain mode to form the fiber knitting layer 120. During the process of weaving the fiber braid 120, at least a portion of the fiber filaments 300 covers the adhesive section 110a to bond the woven fiber braid 120 with the cable main body 110.

In an application scenario, in large-scale cable production, the manufacturing process of the cable can be performed in a semi-automatic or fully-automatic mechanical manner, so as to improve the 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:

step S420A, applying an adhesive on the outside of the cable main body by an adhesive applying device to form an adhesive section.

The specific form of the glue spreading device can be selected according to the requirements of actual production conditions, and the glue spreading device can be used for spreading the adhesive 113 by spraying, smearing, dispensing and other methods. Taking the glue applicator 220 shown in fig. 4-8 and described above in connection with the above description as an example, in one embodiment, the glue applicator 220 applies the adhesive 113 on the outside of the cable body 110 at a predetermined frequency to provide a certain spacing between adjacent glue segments 110 a.

Further, in order to improve the automation level of the production, the glue applying device 220 may perform corresponding actions according to the size of the interval of the glue section 110a to implement the interval automatic glue applying. Assuming that the interval between two adjacent adhesive segments 110a is L and the traveling speed of the cable during production is v, the time interval t for the adhesive applying device 220 to perform the adhesive applying action may be L/v. In an alternative embodiment, the glue applying device 220 includes a glue brush 222, and the glue applying device 220 drives the glue brush 222 to move according to a predetermined frequency to apply the adhesive 113 outside the cable main body 110. In another alternative embodiment, the glue applying device includes a glue sprayer and applies the adhesive 113 by spraying, and the glue applying device drives the glue sprayer according to a predetermined frequency to spray the adhesive 113 outside the cable main body 110. In both of the 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.

The braiding apparatus 230 may be of a type selected for use according to production requirements. Taking the braiding apparatus 230 shown in fig. 4-8 and described above, the braiding apparatus 230 drives the rotating disc 231 and the spindles 232 to rotate according to a predetermined rule, so as to wind the plurality of filaments 300 around the cable body 110 to form the fiber braid 120 having a certain shape.

In some embodiments, step S430A may be followed by step S440A as follows:

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

According to the subsequent processing and use requirements of the cable, marks are arranged at the corresponding positions of the fiber braided layers 120 of the cable through the marking device, so that the effect of facilitating identification is achieved. Taking the marking device 250 shown in fig. 4-6 and 9-12 and described above in connection therewith as an example, the marking device 250 may be disposed adjacent to the braiding device 230, and the braided cable may be conveyed to the marking device 250 for marking. 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 identification of the location of the section of adhesive 110a can be facilitated. In the case where the gluing device 220 applies the adhesive 113 outside the cable body 110 at a predetermined frequency and the traveling speed of the cable is kept constant, the marking device 250 may also perform corresponding actions at the corresponding frequency to set marks on the cable. Thus, a better correspondence of the location of the indicia to the location of the section of adhesive 110a can be achieved.

In some applications, a longer cable needs to be divided into a plurality of shorter cable segments for further processing. For example, when manufacturing a data cable, it is necessary to divide the cable into cable segments of a predetermined length and then connect connectors to the cutouts of the cable segments by riveting or the like. In this scenario, step S450A may also be included after step S440A as follows:

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

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

It will be understood that in the actual cable manufacturing process, not all of the steps described above have to be performed exactly. According to the actual production requirement, some steps in the above steps can be omitted or replaced (for example, the step S450A is omitted), or new steps can be added (for example, a step of performing other processing on the cable is added between the step S440A and the step S450A), and the like.
