Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments introduced herein are provided so that the disclosure may be made thorough and complete, and to fully convey the spirit of the invention to those skilled in the art. Like numbers refer to like elements throughout the specification.

1 shows a partially perspective view of a communication cable 1 according to the invention, and FIG. 2 shows a cross-sectional view of the communication cable 1 shown in FIG. 1.

The communication cable 1 according to the present invention includes a cable core 100 including a plurality of pairs 10 in which two wires each formed of a conductor coated with an insulator are twisted in a spiral shape, and the cable core 100. The outer jacket 400 surrounding the outer side, wherein the outer jacket 400 is integral with the outer jacket to prevent contact between the inner surface of the cable core and the outer jacket and to secure a space in the radial direction And a separation means configured to include a connecting part connected to an inner surface of the outer jacket and a supporting part supporting the cable core by expanding a width at an end of the connecting part. Each structure is demonstrated.

The communication cable 1 according to the present invention may include a cable core 100 including a plurality of pairs 10. Here, the pair is formed by twisting two wires helically formed of a conductor coated with an insulator. Although the communication cable 1 according to the present invention shown in Figs. 1 and 2 is shown to include four pairs 10, the number of pairs 10 is further increased according to the requirements of the communication standard. Can be.

Each conductor may be made of aluminum, copper, or annealed copper wire. In addition, as the diameter of the conductor decreases, the C (capacitance) value decreases and the conductor resistance increases, so that the attenuation width becomes large, and a diameter of about 24 AWG may be mainly used.

The insulator covering the conductor may be made of low density polyethylene (LDPE, Low Density Polyethylene), medium density (MDPE, Medium Density Polyethylene), or high density polyethylene (HDPE, High Density Polyethylene). In some cases, an insulator having a dielectric member may be applied.

In addition, the color of the insulator covering each conductor is generally configured differently.

The four pairs 10 illustrated in FIGS. 1 and 2 may constitute the core 100 in a state in which the four pairs 10 are spaced apart from each other by the cross separator 20.

As shown in the cross-sectional view of FIG. 2, the separator 20 has a cross section, is disposed in the cable in a gently spirally twisted state, and one pair 10 in a space divided into four by the separator 20. ) May be arranged. Each pair 10 may be spaced apart as much as possible by the separator 20, and the interference phenomenon may be minimized.

That is, the separator 20 partitions each pair, provides an accommodation space of each pair, and each pair 10 may be seated in each accommodation space.

The separator 20 may perform a function of minimizing NEXT (near-end crosstalk) that may be deepened when the distance between pairs is reduced. The near-end crosstalk may be aggravated as the grade according to the communication speed or frequency increases. Therefore, when not using shielding means for each pair (metal tape, etc.), a method of increasing the distance between each pair can be used to alleviate near-end crosstalk, and a separator is used as a method of increasing the distance between each pair. Sometimes. In addition, as the communication cable grade increases, the width and thickness of the separator must also increase to increase the distance between the pairs, thereby minimizing NEXT (near-end crosstalk), but the width and thickness of the separator 20 need to be compromised with the cable diameter.

The present invention omits a shielding layer for shielding each pair 10 while satisfying a required communication class, for example, CAT.6A or higher, and thus, a transmission rate of 10 Gbps or more in a transmission band of 500 MHz or more, as described below. In the range of satisfying the diameter of the communication cable of 8.1 mm (mm) to 8.5 mm (mm), it is preferable to sufficiently secure the width and thickness of the separator to minimize near-end crosstalk.

In addition, an outer jacket 400 may be provided on an outer side of the core 100. The outer jacket 400 is configured to serve as a cable sheathing material, such as polyethylene, polyvinyl chloride, or halogen-free low smoke zero halogen or low smoke free of halogen (LSZH). It can be configured as. Among them, LSZH is characterized by low smoke generation during ignition, and by adopting such halogen-free low flame retardant as a sheath member of communication cable, smoke density standard, halogen concentration standard, Toxic and low flammability standards are met.

As described above, the wires constituting each pair (10a, 10b, 10c, 10d) is a conductor (10a1, 10a2, 10b1, 10b2, 10c1, 10c2, 10d1, 10d2) is an insulator (10a3, 10a4, 10b3, 10b4) , 10c3, 10c4, 10d3, and 10d4, and the wires constituting the

pairs

10a, 10b, 10c, and 10d remain twisted with each other.

The pitch of the pair of wires twisting each pair constituting the

pairs

10a, 10b, 10c, and 10d may be configured differently, and the insulators 10a3, 10a4, 10b3, 10b4, 10c3, 10c4, and 10d3 surrounding the conductor , 10d4) may have different colors.

The cable core 100 constituting the communication cable 1 according to the present invention will be described taking the case of including the first pair 10a to the fourth pair 10d as an example.

Although the communication cable 1 according to the present invention satisfies the Cat.6A class or more standard having a transmission rate of 10 Gbps or more in a transmission band of 500 MHz or more, as shown in FIGS. 1 and 2, the communication cable ( 1) uses a method of changing the structure of the outer jacket 400 without providing a separate metal shielding layer surrounding each pair 10 or the core 100.

In general, the communication cable 1 has a characteristic impedance, propagation delay, delay skew, attenuation, in terms of electrical characteristics between the pairs 10 constituting the cable. PS NEXT (Power Sum Near-End Crosstalk) loss, Pair-to pair Near-End Crosstalk (NEXT) loss, PS Power Sum-Equallevel Far-End Crosstalk (ELFEX) loss, Pair-to pair Equal-level Far-End Crosstalk loss, Return Loss, etc. should be considered, and in the Cat.6A or higher standard, in addition to the electrical characteristics between the pairs 10 constituting the cable, interference between adjacent cables, for example, external interference or external crosstalk The electrical characteristics of the back should be considered.

In the electrical characteristics between the pair 10 and the adjacent cable, as the UTP grade is increased, the margin of each electrical characteristic is decreased and the interference phenomenon is increased, so that a shielding layer made of metal is conventionally applied to solve this problem. As it is complicated and causes an increase in cost, the present invention proposes a new structure as described below.

The communication cable 1 according to the present invention uses a method of securing a margin of various electrical characteristics by lowering the effective dielectric constant? Of the cable itself with respect to electrical characteristics between the plurality of pairs 10. In addition, a method of lowering the effective dielectric constant of the cable itself may consider a method of maximizing an empty space, which is an accommodation space of the air layer, inside the cable.

In addition, a method of increasing the distance between the cores 100 of the adjacent communication cable 1 may be used unless a separate metal shielding layer is used to minimize external interference. However, in order to increase the spacing between the cores 100 of adjacent cables, it is also not preferable to configure the diameter of each cable without limit. As a result, when the outer diameter of the cable is constant, a method of increasing the distance between the cores 100 of adjacent cables may consider a method in which the core 100 of each cable is disposed at the center of the cable as much as possible.

The communication cable 1 according to the present invention is provided in the outer jacket 400, and maximizes the size of the empty space inside the cable through a separation means having a shape in which the width is expanded toward the center of the cable and at the same time a plurality of pairs (10) The cable core 100 is configured to be arranged in the center of the cable.

Specifically, this will be described with reference to FIG. 3.

3 shows a detailed cross-sectional view of the embodiment shown in FIGS. 1 and 2 of an outer jacket 400 constituting a communication cable 1 according to the invention.

The outer jacket 400 constituting the communication cable 1 according to the present invention is provided on its inner surface to prevent contact between the plurality of pairs 10 and the inner surface of the outer jacket 400 and to secure a space in the radial direction. Spacer means having a cross-sectional shape of the width is extended in the center direction of the cable may be provided. The separation means may have the form of a support arm 300 protruding from the inner surface of the outer jacket 400.

As shown in FIG. 3, the support arm 300 as the separation means may be integrally formed with the outer jacket 400 and may be provided in plurality. In the embodiment shown in Figure 3, the four support arms 300 are shown in the circumferential direction along the inner surface of the outer jacket 400, the four are spaced apart at equal intervals is shown an example provided long along the longitudinal direction of the cable.

The support arms 300 as the respective separation means have a shape in which the width of the support arm 300 extends from the inner surface of the outer jacket 400 toward the center of the cable. The support arm 300 may have, for example, a T-shape or a Y-shape, an inverted triangle or an inverted trapezoid.

In the embodiment illustrated in FIG. 3, the support arm 300 protrudes from the inner surface of the outer jacket 400 to have an enlarged width in an area supporting the core 100.

Specifically, the support arm 300 as the separation means has a width at the end of the connecting portion 310 and the connecting portion 310 is connected to the inner surface of the outer jacket 400 is the plurality of pairs 10 or core 100 It may be configured integrally, including a support 360 for supporting.

In addition, as illustrated in FIG. 3, a plurality of grooves 360h1 and 360h2 are formed on the top surface 360s of the support arm 300. In addition, as illustrated in FIG. 3, the support parts 360 of the plurality of support arms 300 are configured to be spaced apart from each other so as to have a shape corresponding to a part of an arc of one circle.

In this manner, a first space S1 may be formed between the lower surface of the support part 360 and the inner surface of the outer jacket 400, and the grooves 360h1 of the upper surface 360s of the support arm 300 may be formed. The second space S2 and the third space S3 may be formed inside the 360h2, and the fourth space S4 may be formed between the side surfaces of the support 360 of the adjacent support arm 300.

By such a structure, the core 100 may be supported to be stably disposed at the center of the cable by the support part 360 of the support arm 300 and at the same time, various empty spaces may be secured in the cable.

In this way, the space inside the cable is increased to lower the effective permittivity ε, thereby improving the margin of electrical characteristics between the pairs 10, and allowing the cable core of the communication cable to be positioned as close to the center of the cable as possible. Increasing the spacing between the cores of the cable also minimizes extraterrestrial interference.

In addition, the grooves 360h1 and 360h2 formed on the upper surface 360s of the support 360 of the support arm 300 may be long in the longitudinal direction (ie, the longitudinal direction of the communication cable) of the support 360.

As shown in FIG. 2, grooves 360h1 and 360h2 formed on the upper surface 360s of the support 360 of the support arm 300 may not be seated by inserting a specific pair 10 constituting the cable core 100. It is preferable that the size is not configured.

That is, when the specific pair 10 or the wires constituting the core 100 is inserted into the grooves 360h1 and 360h2 that are artificially formed to reduce extraterrestrial interference with the adjacent cable, the spacing of the core 100 of the adjacent cable is rather increased. Because it is reduced.

In the embodiment shown in Figure 3, the groove (360h1, 360h2) is shown that the three spaced apart on the upper surface (360s) of the support portion 360 of each of the separation means, the number and support of the support arm 300 The width and number of each of the grooves 360h1 and 360h2 can be increased or decreased depending on the size of the width 360, the insulation outer diameter of the wire constituting the pair 10, or the major pitch.

In addition, since the support arm 300 is provided in plural numbers, the plurality of support parts 360 have a shape corresponding to the plurality of spaced arcs of the circular arc of one circle. The fourth space s4 is secured, but since the empty space is relatively insufficient in the radial direction penetrating through the connecting portion 310, a center of the plurality of grooves 360h1 and 360h2 formed on the upper surface 360s of the support 360 is provided. The width of the formed groove 360h1 may be configured to be the largest to minimize the variation of the area of the radial space.

In addition, the connecting portion 310 of the support arm 300 as the separation means may be configured to be narrower toward the support portion 360 side. By such a structure, the restoring flexibility (or elasticity) of the support part 360 is secured and the connection part 310 is prevented from being bent, thereby stably supporting the core 100.

In addition, the connecting portion 310 of the separation means is narrower in width toward the support portion 360 side structure can be implemented in a way that the side of the connecting portion 310 is configured in the radial direction.

In addition, as shown in FIG. 3, in addition to the side of the connection part 310, the side of the support part 360 and the side surfaces of the grooves 360h1 and 360h2 formed in the support part 360 also face the cable center direction. It may be configured to be.

Due to the structure, the openings of the grooves 360h1 and 360h2 formed in the support part 360 are narrow and the inside thereof is widened, thereby maximizing the empty space inside the cable and preventing wires from being seated inside. There is an advantage to that.

With respect to the outer jacket 400 of the communication cable 1 according to the present invention, the first angle θ1, which is the angle θ1 of the arc corresponding to the support 360 of each support arm 300, is about 50. 2 to 70 degrees, and the second angle θ2 which is the angle θ2 of the arc corresponding to the interval between the support parts 360 is 20 degrees to 40 degrees, and the groove formed on the upper surface 360s of the support part 360 ( The third angle θ3, which is the angle of the arc corresponding to the groove 360h1 formed at the center of the 360h1 and 360h2, is configured to be about 5 degrees to 15 degrees to maximize the empty space inside the cable, and the core 100 of the cable It was confirmed that the electrical properties between the pair 10 and the electrical properties related to extraterrestrial interference required in the Cat.

3 illustrates an example in which the first angle θ1 is about 60 degrees, the second angle θ2 is about 30 degrees, and the third angle θ3 is about 10 degrees.

In addition, with respect to the thickness of each of the inner configuration of the outer jacket, the thickness t1 of the outer jacket 400, the thickness t2 of the connection portion 310 of the support arm 300, the support portion 360 The depth t3 of the grooves 360h1 and 360h2 formed in the grooves and the total thickness t4 of the support part 360 may be determined according to the entire cable diameter.

The thickness t2 of the connection part 310 of the support arm 300 and the depth t3 of the grooves 360h1 and 360h2 formed in the support part 360 may be configured in a corresponding size, and the outer jacket 400 ), The thickness t1 may be greater than the thickness t2 of the connection part 310 of the support arm 300 and the depth t3 of the grooves 360h1 and 360h2 formed in the support part 360. It has been experimentally confirmed that the thickness t1 of the outer jacket 400 is preferably smaller than the total thickness t4 of the support part 360.

If the thickness t1 of the outer jacket 400 is configured to be smaller than the thickness t2 of the connection part 310 of the support arm 300, the connection part 310 stably supports the core 100. In addition, the outer jacket 400 is not preferable because it is easily deformed by an external force.

In addition, even when the depth t3 of the grooves 360h1 and 360h2 formed in the support part 360 is large, the pairs or wires constituting the core 100 may be seated in a specific groove, and thus, are disposed between the grooves. The height of the wall supporting the pair or wires (same as the depth of the grooves) should be limited to prevent the wires or pairs from being inserted into the grooves in order to prevent the wall from bending or crushing.

As a result, the respective separation means within the allowable thickness of the outer jacket 400, the depth t3 of the grooves 360h1 and 360h2 of the support part 360, or the thickness t2 of the connection part 310 is allowed. The connection portion 310 of the support stably supports the cable core toward the center of the cable, it is preferable to determine the appropriate size so that a particular pair or wire is not received in the grooves (360h1, 360h2) of the support portion 360, experimentally described later The thickness t1 of the outer jacket 400 in the range of 8.1 mm (mm) to 8.5 mm (mm), which is the outer diameter of the preferred communication cable, is the thickness t2 of the connection portion 310 of the support arm 300. And the depth t3 of the grooves 360h1 and 360h2 formed in the support part 360, it was concluded that it is desirable to be configured larger.

In addition, in the general use of the communication cable 1 according to the present invention, when the diameter of the communication cable 1 is about 8.1 millimeters (mm) to 8.5 millimeters (mm), it is required in Cat.6A grade. It was confirmed that electrical characteristics between the pairs 10 and electrical characteristics related to extraterrestrial interference could be satisfied.

4 shows a detailed cross-sectional view of another embodiment of an outer jacket 400 constituting a communication cable 1 according to the invention. Descriptions duplicated with the description with reference to FIG. 3 will be omitted. 3 illustrates an example in which a plurality of grooves are formed on an upper surface of a support part of the support arm 300 to maximize empty space, but the embodiment illustrated in FIG. 4 illustrates a plurality of protrusions on an upper surface of the support arm. The same effect can be obtained using the forming method.

That is, the difference between the embodiment shown in FIG. 3 and the embodiment shown in FIG. 4 is distinguished in the method for forming a void inside the cable. That is, the embodiment shown in Figure 3 to form the grooves (360h1, 360h2) in the support surface (360s, upper surface of the support portion 360) of the support arm 300 constituting the separation means to secure the empty space inside the cable Rather than the method of forming a projection (360p1, 360p2) on the support surface (360s) is used.

A plurality of protrusions 360p1 and 360p2 contacting the cable core may be spaced apart from each other in the width direction of the support surface 360s on the upper surface of each of the support arms 300. In this case, the plurality of protrusions 360p1 and 360p2 may be provided long along the longitudinal direction of the cable, similarly to the grooves 360h1 and 360h2 of the embodiment shown in FIG. 3.

By forming the protrusions 360p1 and 360p2, an empty space may be secured inside the cable, such as the grooves 360h1 and 360h2, and similarly, each protrusion may be formed in the process of forming a plurality of protrusions 360p1 and 360p2. It is preferable that the width between the projections 360p1 and 360p2 provided at the center of the support part 360 of the space between 360p1 and 360p2 is maximized, and the thickness t1 of the outer jacket 400 is the support arm. The thickness t2 of the connection part 310 of the 300 may be greater than the thickness t3 ′ of the protrusions 360p1 and 360p2 formed in the support part 360, and the connection part 310 of the support arm 300 may be formed. ), The thickness t2, the thickness t3 'of the protrusions 360p1 and 360p2 formed on the support 360, and the thickness t4' of the support 360 are various combinations according to the type of cable and the diameter of the cable. This was confirmed to be possible.

By the structure of the communication cable 1 according to the present invention shown in Figures 1 to 4, the cable core 100 composed of each pair 10 or a plurality of pairs 10 constituting the UTP communication cable (1) ) Can satisfy Cat.6A's communication standards without shielding with a separate metal shielding layer.

That is, according to the communication cable 1 according to the present invention, the width of the support arm 300 as a separation means provided on the inner surface of the outer jacket 400 constituting the communication cable 1 increases toward the center of the cable. Since it has a shape, the core 100 can be stably supported and the air layer or the empty space can be sufficiently secured inside the cable, so that the overall effective dielectric constant of the communication cable 1 is lowered so that the attenuation margin and propagation speed of the communication cable 1 are lowered. It is possible to improve the margin and the like, so that the core 100 consisting of a plurality of pairs 10 by the support arm 300 as the separation means is arranged in the center of the communication cable 1 so that each core 100 of the adjacent cable It is confirmed that extraneous interference between adjacent cables can be minimized by separating the distances between the cables.
