Definitions
- the present invention relates to a highly shielded Ethernet cable for vehicles and a method for manufacturing the same, and more particularly, to a highly shielded Ethernet cable for vehicles capable of improving LCL/LCTL electrical characteristics and a method for manufacturing the same.
- Ethernet cables are being applied to many applications in general.
- automotive Ethernet market is gradually expanding due to the development of autonomous driving and infotainment, and the demand for Ethernet cables is increasing significantly.
- infotainment refers to an integrated multimedia system that combines information and entertainment.
- Ethernet cables currently in use are limited in terms of data speed and capacity, and are unable to keep up with the pace of application development. Therefore, the development of an alternative cable that can transmit and receive more data is urgent.
- Ethernet cables are largely divided into UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair). Since STP has better noise characteristics due to shielding than UTP, the development direction of high-performance Ethernet cables is moving toward the STP structure.
- Class 1 Cables with STP structure are broadly classified into two types, Class 1 and Class 2.
- Class 1 has the characteristic of requiring LCL/LCTL (TCL/TCTL) items along with lower shielding characteristics compared to Class 2, while Class 2 requires higher shielding characteristics compared to Class 1 but does not require LCL/LCTL (TCL/TCTL) items.
- the technical problem to be achieved by the present invention is to propose a highly shielded Ethernet cable for vehicles, which has high shielding characteristics and satisfies a certain level of LCL/LCTL values, and is advantageous for high-speed and large-capacity data transmission, and a method for manufacturing the same.
- a highly shielded Ethernet cable for a vehicle includes a core portion formed by twisting a pair of cores including an insulator wrapping a conductor with each other at a preset pitch, a tape layer formed by wrapping a tape around an outer periphery of the core portion in a direction opposite to a direction in which the pair of cores are twisted, a bedding layer formed in a form surrounding the tape layer, a shielding layer formed in a form surrounding the bedding layer, and a sheath layer formed in a form surrounding the shielding layer.

- a is the width of the tape
- b is the angle at which the tape is wrapped.
- the width of the above tape is in the range of 5 mm to 20 mm, and the tape can be wrapped to form an angle within the range calculated by the above formula based on the usage width based on the central axis of the core portion.
- the above tape can be selected from a group of polymer series tapes.
- the preset pitch of the core portion formed by twisting the above pair of cores may be 7 mm to 50 mm.
- the tape wrapping the outer periphery of the above core portion can be wound in a wrap shape in which a portion of the width of the tape overlaps.
- a method for manufacturing a highly shielded Ethernet cable for a vehicle includes a step of forming a core by twisting a pair of cores including an insulator wrapping a conductor in one direction at a preset pitch, a step of forming a tape layer by wrapping a tape in one direction and an opposite direction on the outside of the core, a step of forming a bedding layer surrounding the tape layer, a step of forming a shielding layer surrounding the bedding layer, and a step of forming a sheath layer surrounding the shielding layer.
- a is the width of the tape
- b is the angle at which the tape is wrapped.
- the width of the above tape is in the range of 5 mm to 20 mm, and the tape can be wrapped to form an angle within the range calculated by the above formula based on the usage width based on the central axis of a pair of cores.
- a vehicle-use high-shielding Ethernet cable that satisfies both the high LCL/LCTL characteristics required for Class 1 and the high shielding characteristics required for Class 2, and a method for manufacturing the same.

- a component when it is mentioned that a component is on another component, it means that it can be formed directly on the other component, or a third component can be interposed between them. Also, in the drawings, the thickness of the components is exaggerated for the effective explanation of the technical contents.
- first element operates or is executed ON a second element (or component)
- first element operates or is executed in an environment in which the second element (or component) operates or is executed, or that the first element (or component) operates or is executed through direct or indirect interaction with the second element (or component).
- FIG. 1 is a cross-sectional view of a highly shielded Ethernet cable for a vehicle according to one embodiment of the present invention.
- a highly shielded Ethernet cable for a vehicle (hereinafter referred to as an 'Ethernet cable') according to one embodiment of the present invention is composed of a core portion (100), a tape layer (200), a bedding layer (300), a shielding layer (400), and a sheath layer (500).
- the core portion (100) is formed by twisting a pair of cores (110, 120) including an insulator (114, 124) surrounding a conductor (112, 122) in one direction at a preset pitch, that is, in one direction of either the S-axis or the Z-axis.
- the preset pitch at which the pair of cores (110, 120) are twisted can be a value in the range of 7 mm to 50 mm.
- the conductor (112, 122) may be formed in a shape in which a plurality of conductor wires are arranged around a central wire of one strand. As illustrated, six conductor wires may be arranged around a central wire of one strand. However, this is merely an example, and 6N conductor wires may be arranged around a central wire of one strand, for example, 1+6 wires, 1+6+12 wires, etc., per N layers.
- the conductor (112, 122) is formed in such a shape to maintain a stable conductor shape.
- the conductor (112, 122) may be made of a metal material such as copper, aluminum, or silver, or an alloy thereof.
- the insulator (114, 124) is formed in a shape that surrounds the outer periphery of the conductor (112, 122), and can be formed by extrusion of an insulating composition including a polymer resin having electrical insulating properties as a base resin, etc.
- the polymer resin is not particularly limited as long as it can implement electrical insulating properties, but may include, for example, a polyolefin-based resin such as polyethylene, ethylene vinyl acetate, ethylene ethyl acetate, and ethylene butylacrylate.
- the tape layer (200) is formed by wrapping the tape around the outer circumference of the core portion (100) in the opposite direction to the direction in which the pair of cores (110, 120) are twisted. What is important when forming the tape layer (200) is that the tape must be wrapped in the opposite direction to the direction of the twisted wires by the core portion (100). That is, if the direction of the twisted wires is Z-twisted, the tape must be wound in the S-twisted direction, and if the direction of the twisted wires is S-twisted, the tape must be wrapped in the Z-twisted direction. The reason why the direction of the tape must be opposite to that of the twisted wires will be examined in more detail with reference to FIGS. 4 and 5.
- the bedding layer (300) is formed in a form that surrounds the tape layer (200).
- the bedding layer (300) is arranged to fill the empty space between the core and the shielding layer, and this structure can improve the circularity of the Ethernet cable and make it structurally stable.
- the bedding layer (300) is arranged in the middle of the tape layer (200) and the shielding layer (400).
- the bedding layer (300) may be made of a resin such as polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), polypropylene (PP), or fluorinated ethylene propylene (FEP).
- PVC polyvinyl chloride
- PE polyethylene
- XLPE cross-linked polyethylene
- PP polypropylene
- FEP fluorinated ethylene propylene
- the shielding layer (400) is formed in a form that surrounds the bedding layer (300).
- the shielding layer (400) performs the function of reflecting or absorbing and blocking electromagnetic waves emitted to the outside from the core part (100) and electromagnetic waves attempting to penetrate into the Ethernet cable from the outside.
- the shielding layer (400) may include a first shielding layer (410) and a second shielding layer (420).
- the first shielding layer (410) is formed in a form that surrounds the bedding layer (300) so as to be in contact with the bedding layer (300), and an aluminum tape can be applied.
- the first shielding layer (410) can be formed by an aluminum tape, such as an aluminum-mylar tape in which aluminum foil is attached to a polyester film.
- the second shielding layer (420) is formed in a form that surrounds the first shielding layer (410), and a metal braid may be applied.
- the second shielding layer (420) may be formed by a metal braid, such as a tin-plated copper braid.
- the sheath layer (500) is formed in a form that surrounds the shielding layer (400).
- the sheath layer (500) is formed in a form that surrounds the shielding layer (400), that is, the second shielding layer (420), and forms the outermost layer of the Ethernet cable.
- the sheath layer (500) wraps the entire core portion (100) to protect the core portion (100) from external pressure or impact.
- the sheath layer (500) may be formed by polyvinyl chloride resin, polyethylene resin, fluororesin, etc., and among them, it may be formed by extrusion of an outer composition that includes polyvinyl chloride resin having excellent flexibility as a base resin.
- FIG. 2 is a perspective view illustrating a core and a tape layer of a highly shielded Ethernet cable for a vehicle according to one embodiment of the present invention
- FIG. 3 is a conceptual diagram explaining the width and angle of a tape forming a tape layer in a highly shielded Ethernet cable for a vehicle according to one embodiment of the present invention.
- conductors (112, 122) made of wires are twisted at a constant pitch to form a core portion (100).
- a tape layer (200) is formed by tape on top of the core portion (100).
- the tape layer (200) is formed over the entire core portion (100), and is formed by winding the tape in a direction opposite to the direction in which a pair of cores (110, 120) are twisted.
- the Ethernet cable structure should be uniform overall.
- the extrusion of the material is difficult because the core part (100) is twisted at a certain pitch.
- the pressure may cause the cores to gap each other or the pitch may become uneven.
- the core part (100) is formed by winding the tape in the opposite direction to the direction of the twisted wire.
- a pair of cores (110, 120) form a tape layer (200) by winding the tape in opposite directions to each other.
- the direction in which the tape forming the tape layer (200) is wound and the angle at which the tape is wound are schematically illustrated in FIG. 3.
- the core portions (100) are twisted together at a preset pitch to form a tape, and then the tape is wound.
- the tape for forming the tape layer (200) has a predetermined width and is wound obliquely at a predetermined angle to wrap the core portion (100) composed of a wire.
- the width of the tape can be selected from a range of 5 mm to 20 mm. At this time, when selecting the tape, the width of the tape should not exceed 20 mm, which is the maximum limit for securing a stable structure of the filament.
- a part of the width of the tape is wrapped in a shape in which it overlaps (overlap), and this kind of winding is called a wrap shape
- FIG. 3 illustrates a tape wound in such a wrap shape (the part that overlaps and goes down is expressed as a dashed line).
- a is the width of the tape (mm) and b is the angle at which the tape is wrapped (deg).
- the tape be wrapped around the core portion (100) at an angle of 29 to 52 degrees based on the central axis of the core, which is vertical, when the tape is wrapped according to mathematical expression 1. Since the width and angle of the tape must satisfy mathematical expression 1, the angle at which the tape is wrapped may also be different if the width of the tape is different.
- Figure 4 is a drawing to explain an incorrect example of tape layer formation.
- a pair of cores (110, 120) are formed to form a tape layer (200) in the opposite direction to the winding direction. That is, the winding direction of the core portion (100) and the winding direction of the tape should be opposite to each other. The reason for this is to expect an LCL/LCTL improvement effect.
- Fig. 4 corresponds to the case where both the twisted pair wire and the tape are formed in the S-stretch direction or the Z-stretch direction.
- the tape layer (200) As shown in (a) to (c), if the formation of the tape layer (200) has an uneven structure, it has a negative effect on the LCL/LCTL characteristics. Therefore, when manufacturing an Ethernet cable according to the present invention, the tape layer (200) must be formed by winding the tape in the opposite direction in which a pair of cores (110, 120) are formed.
- Figure 5 is a graph showing the results of LCL/LCTL evaluation according to the formation direction of the tape layer.
- Ethernet cables were manufactured when the winding direction of a pair of cores (110, 120) and the winding direction of the tape forming the tape layer (200) were in the same direction and when they were in opposite directions, and then the LCL characteristics and LCTL characteristics were observed for each and represented in a graph.
- the LCL/LCTL values should be lower than the specification values to indicate good characteristics.
- LCL refers to a phenomenon in which common mode is converted to differential mode due to an unbalanced structure such as core-to-core length and outer diameter, and attenuation and mode conversion occur simultaneously due to a section that causes a reflection signal and returns to the input (Return Loss).
- LCTL refers to a phenomenon in which, although similar in cause to LCL, it is output as is to the output terminal instead of returning to the input terminal (Insertion Loss).
- LCL and LCTL are measures of how symmetrical the cable structure is, and securing a uniform (symmetry) structure throughout the cable is essential for mode conversion suppression.
- mode-converted signals are recognized as noise at the receiver, which can interfere with data transmission and reduce transmission efficiency, so satisfying a certain level of LCL/LCTL values is advantageous for high-speed and large-capacity data transmission.
- (a) shows the results of evaluating the LCL characteristics according to frequency of a cable in which a pair of cores (110, 120) and a tape layer (200) are formed in the same direction along with the disclosed LCL specifications, and an Ethernet cable according to the present invention.
- (b) shows the results of evaluating the LCTL characteristics according to the frequency of a cable in which a pair of cores (110, 120) and a tape layer (200) are formed in the same direction along with the published LCTL specifications, and an Ethernet cable according to the present invention.
- the Ethernet cable according to the present invention exhibits improved LCL/LCTL characteristics compared to a cable in which a pair of cores (110, 120) and a tape layer (200) are formed in the same direction, and satisfies the LCL/LCTL characteristics required for Class 1.
- Figures 6 to 8 are graphs showing the results of LCL/LCTL evaluation according to the angle of the tape forming the tape layer.
- the tape wrapping the core portion (100) satisfies the mathematical expression 1 in its width and wrapping angle. Accordingly, in this embodiment, in order to compare when the width and angle of the tape satisfy and do not satisfy the mathematical expression 1, the LCL and LCTL characteristics were observed by varying the wrapping angle of the tape. At this time, the width a of the tape was applied equally as 8 mm for all cases.
- the LCL and LCTL characteristics are shown in a graph after the cable was manufactured by setting the tape angle b to 15 degrees.
- the LCL and LCTL characteristics are shown in a graph after the cable was manufactured by setting the tape angle b to 40 degrees.
- the LCL and LCTL characteristics are shown in a graph after the cable was manufactured by setting the tape angle b to 60 degrees.
- the graphs expressed in the form of thick straight lines in Figs. 6 to 8 indicate values according to the specifications of LCL and LCTL, respectively.
- Fig. 7 shows a case where the angle b of the tape is formed at 40 degrees, which falls within the range of 29 to 52 degrees, and it appears that both the LCL/LCTL characteristics show improved results.
- the tape forming the tape layer (200) by mathematical expression 1 must be formed at an angle in the range of 29 to 52 degrees, but a cable including a tape layer (200) formed at an angle that does not satisfy mathematical expression 1, as shown in FIGS. 6 and 8, does not have improved LCL/LCTL characteristics.
- the Ethernet cable according to the present invention including a tape layer (200) formed at an angle that satisfies mathematical expression 1 not only has improved LCL/LCTL characteristics, but also satisfies the LCL/LCTL characteristics required by Class 1.
- Class 1 requires high LCL/LCTL characteristics
- Class 2 requires high shielding characteristics.
- an Ethernet cable was manufactured that satisfies the LCL/LCTL characteristics required for Class 1 and also the shielding characteristics required for Class 2.
- FIG. 9 is a flow chart for explaining a method for manufacturing a highly shielded Ethernet cable for a vehicle according to one embodiment of the present invention.
- the pair of cores (110, 120) are twisted in one direction to form a core portion (100) (S610).
- the direction in which the pair of cores (110, 120) are twisted can be either S-twisted or Z-twisted.
- a tape layer (200) is formed in a form that wraps around the outer periphery of the core portion (100) (S620).
- the tape layer (200) may be a polymer-based tape, and is formed in a form that wraps around the core portion (100) in a direction opposite to the direction in which the pair of cores (110, 120) are twisted. That is, when the pair of cores (110, 120) are wound in the S-direction, the tape layer (200) is formed in the Z-direction, and when the pair of cores (110, 120) are wound in the Z-direction, the tape layer (200) is formed in the S-direction.
- a bedding layer (300) is formed on the outer periphery of the tape layer (200) (S630), a shielding layer (400) is formed on the outer periphery of the bedding layer (300) (S640), and a sheath layer (500) is formed on the outer periphery of the shielding layer (400) (S650).
- the shielding layer (400) may include a first shielding layer (410) and a second shielding layer (420).
- an extruder (not shown) is used to fill a material into a wire twisted at a certain pitch, and the wire rotates when it enters the extruder. Accordingly, it was a very difficult task to extrude a certain amount of material into the groove between a pair of cores (110, 120).
- the Ethernet cable according to the present invention solves this problem by forming a tape layer (200) on a pair of cores (110, 120).
- the tape layer (200) is formed by winding the tape in the opposite direction to the direction in which a pair of cores (110, 120) are wound, it is possible to form a tape layer (200) of uniform shape. As a result, there is an advantage of a maximized LCL/LCTL improvement effect and high shielding.
