The present invention relates to a UTP cable and a separator used therein, and more particularly, to a separator having a shape capable of minimizing internal interference during high-speed transmission of data and a UTP cable including the same.

1 is a perspective view of a UTP cable according to the prior art, and FIG. 2 is a cross-sectional view of the UTP cable according to the prior art.

As shown in FIGS. 1 and 2, a UTP cable, which is generally used as a communication cable, spirally twists the conductors 110 formed by covering a conductor 100 such as copper with an insulator to form a stranded wire part 120. In addition, the individual stranded portion 120 is configured to form a re-coated form of about four.

Such UTP cable has recently emerged as an important problem in increasing information transmission capability according to the development of information and communication technologies such as ATM and Ethernet, and has been developed and supplemented in order to realize such an increase in transmission capability.

On the other hand, according to the global convention, the UTP cable is classified by a category (Category or Cat.) And a number according to the signal transmission capability, the higher the number has a higher transmission characteristics.

For example, 16 MHz for Cat. 3, 20 MHz for Cat. 4, and 100 MHz for Cat. 5 can be transmitted. The higher the modulation frequency, the greater the amount of information per unit time.

 However, the higher the modulation frequency, the higher the noise phenomenon caused by interference between cables and impedance change in the wires, which makes it difficult to separate the signal from the signal receiver.

For this reason, the signal transmission limit of UTP cable has been considered to be about 155Mbps (Megabit per sec).

However, according to the recent development of information transmission equipment technology, it is possible to compensate for signal degradation due to interference in a cable by using a compensation method by digital signal processing (DSP) equipment or the like. The 1000Mbps (1Gbps) transmission was made possible, and the IEEE (Institute of Electrical and Electronics Engineers) standard committee officially standardized 1000 Base-T as an Ethernet standard by 1999.

On the other hand, the recent development of related technologies, such as moving picture transmission technology, is likely to require a cable that can enable a higher level of information transmission in the near future. R & D is being conducted competitively, and a special committee for establishing standards for high-speed information transmission cables is being established in IEEE.

However, in order to increase the transmission capacity, high frequency is generally used, and when the high frequency is used, internal interference (Power Sum Near and Cross Talk; PSNEXT) occurs between each twisted pair inside the UTP cable.

On the other hand, with respect to the plurality of twisted pairs 120 included in the UTP cable, the distance between the centers of the conductors 110 is d, and the distance between the centers of the twisted pairs 120 is D, Internal interference is proportional to (d / D) ² .

Therefore, according to the above formula, it can be seen that as the distance D between the centers of the respective twisted pairs 120 increases, internal interference between the twisted pairs decreases.

Conventionally, in order to minimize the internal interference between the twisted pairs 120 in such a UTP cable, a cable including a separator 130 that can space the distance between each twisted pair 120 has been proposed.

However, in recent years, as high frequency signals are used for high-capacity transmission of 1 Gbps and 10 Gbps, in order to further reduce the internal interference between the twisted pairs 120, to increase the distance between the centers of the twisted pairs 120. It is necessary to increase the thickness of the partition wall of the separator 130. In this case, the size of the cross-sectional area of the entire UTP cable is increased, and the material consumption required for manufacturing the separator is greatly increased.

In addition, the increase in the thickness of the separator 130 reduces the flexibility of the UTP cable as a whole, it causes the difficulty of laying in the complex structure.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a UTP cable that can reduce the internal interference between the twisted pair by increasing the distance between the center of the twisted pair included in the cable. will be.

It is still another object of the present invention to provide a UTP cable which can increase the distance between the centers of twisted pairs without increasing the overall size of the separator or cable.

It is still another object of the present invention to provide a UTP cable which can reduce the material consumption required for manufacturing while increasing the distance between the centers of stranded portions.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention.

Prior to this, the terms used in this specification and claims should not be construed in a dictionary sense, and the inventors may properly define the concept of terms in order to explain their invention in the best way. It should be construed as meaning and concept consistent with the technical spirit of the present invention.

Therefore, the configurations shown in the embodiments and drawings described herein are only preferred embodiments of the present invention, and do not represent all of the technical idea of the present invention, and various equivalents may be substituted for them at the time of the present application. It is to be understood that water and variations may exist.

3 is a perspective view of a UTP cable according to a first embodiment of the present invention, and FIG. 4 is a cross-sectional view of a separator included in the UTP cable according to the first embodiment of the present invention.

3 and 4, the UTP cable according to the present invention includes a plurality of twisted pair portions 14 formed by twisting a plurality of insulation coated conductors 12 and the plurality of twisted pair portions 14. A UTP cable including a separator 20 including partition walls 22 for isolating each other, and a sheath portion 40 surrounding the stranded portion 14 and the separator 20, and the partition wall of the separator 20. At least one of the barrier ribs 22 is formed to have a width that increases in size toward the center O of the separator 20 from the outer ends a, b, c, and d of the barrier ribs. do.

In this case, the conductive wire 12 is formed by forming a wire using a conductor 11 such as copper and then covering the insulator in order to transmit data converted into an electrical signal.

The insulator is formed by adding an additive for imparting stable processing characteristics to low smoke zero halogen (LSZH), which is a polymer having flame retardant properties.

The stranded portion 14 is formed by twisting a plurality of conductor wires at a large pitch at regular intervals, and as shown in FIG. 3, two stranded wires are twisted, but are not limited thereto. Is possible.

In addition, the twisted pair part 14 may be configured to have a structure covering the outside of the twisted conductor 12 to further improve transmission characteristics by reducing signal interference through an increase in shielding effect.

The twisted pair part 14 is included in a plurality of high-speed communication cables, and as shown in FIG. 3, four twisted pair parts 14 are included in the sheath part 40, but are not limited thereto. Various modifications are possible.

On the other hand, in order to suppress the interference between the twisted pairs 14 included in the cable, the large pitch of the twisted pairs 14 is formed different from each other, preferably has a difference of 0.2mm or more.

A plurality of twisted pairs 14 as described above are twisted with a predetermined pitch in the longitudinal direction of the cable, the twist pitch of the entire twisted pairs 14 is referred to as a collective pitch.

The cable also includes a sheath portion 40 configured to surround the entire twisted pair portion 14 as described above and form an appearance.

Here, the sheath portion 40 not only mechanically protects the stranded portion 14, but also serves to block alien crosstalk caused by electromagnetic waves generated from other adjacent cables or other electronic equipment. do.

In general, the sheath portion 40 is formed of an insulating material such as polyethylene, PVC, or an olefin (Olefin) -based polymer material, the thickness is preferably configured to have a value in the range of 0.3 ~ 1.5mm.

Because, if the thickness of the sheath portion 40 is less than 0.3mm, it does not effectively protect the conducting wire 12 from the external interference, if it exceeds 1.5mm, the thickness of the cable is thickened to increase the weight and flexibility Because it falls.

Preferably, an electromagnetic wave shielding sheath (not shown) made of a conductive material may be further included in the sheath 40 to further increase the blocking effect of external interference.

 In addition, the UTP cable according to the present invention includes a separator 20 for isolating the plurality of twisted pairs 14 from each other.

The separator 20 is radial in cross-section, and includes a partition wall 22 that intersects with each other so as to intersect the main strands 14 to prevent internal interference between the stranded portions 14. The stranded wires 14 are accommodated one by one in the space formed between the fields 22.

In addition, in the state in which the insulated coated wires 12 are twisted as described above to form the stranded portions 14, the separator 20 and the plurality of stranded portions 14 are twisted together at a predetermined collective pitch. A portion of the entire length of the stranded portions 14 may be formed to be in contact with the center region of the separator 20 or the partition walls 22.

Also, as can be seen in FIG. 1, since the centers of the stranded portions are radially disposed with respect to the center of the cross section of the separator, the distance between the minimum centers of the stranded portions is such that the separator 20 spaces the stranded portions 14 from each other. The size of the center region and the width of the partition wall will depend on the width of the partition wall. In particular, the width dimension of the portion closer to the center region of the separator 20 has a greater influence on the distance between the centers of the strands. Can be.

On the other hand, in general, the stranded portions 14 included in the cable are formed with different pitches different from each other, but when the stranded portions 14 having similar pitches are adjacent to each other, internal interference between the stranded portions 14 may occur. This will occur.

The internal interference is influenced by the distance between the centers of the twisted pairs, and when the distance between the centers of the twisted pairs 14 having similar pitches is close, the internal interference is severe, and when the distance is far, the internal interference is rapidly reduced. As described above.

Therefore, in order to reduce internal interference between twisted pair portions, it is important to increase the size of the center region of the separator 20.

Therefore, in order to increase the size of the center region of the separator 20 which has a significant influence on the internal interference, without increasing the overall thickness of the separator 20 to cause unnecessary material cost increase, At least one of the partitions 22 of the partitions 20 included in the separator 20 increases from the outer end portions a, b, c, and d of the partition wall toward the center O of the separator 20. It is formed to have a width of size.

First Example

The separator 20 (see FIG. 4) of the UTP cable according to the first embodiment of the present invention includes four partitions 22 and is characterized in that the surface slopes of the present partitions are constantly configured.

Here, the surface slope means the center of the separator 20 from the outer end of the partition wall having a width (a, b, c, d) to the inner end formed of the width (a1, b1, c1, d1). The ratio of the width (Δy / Δx) increased with respect to the unit length (Δx) towards (O).

Therefore, the constant surface slope means that the ratio of the increased width with respect to the unit length toward the center O of the separator 20 is constant, as shown in FIG. 4, the width of the partition wall. It is shown to be configured to increase linearly toward the center of the separator 20.

Here, the outer end widths (a, b, c, d) and the inner end widths (a1, b1, c1, d1) of the partition wall included in the separator 20 are 1.2 × a ≦ a1 ≦ 3 × a, It is preferable to be comprised in the relationship of 1.2xb <= b1 <= 3xb, 1.2xc <= c1 <= 3xc, and 1.2xd <= d1 <= 3xd.

Here, when the inner end widths a1, b1, c1, and d1 are formed to be less than 1.2 times larger than the outer end widths a, b, c, and d, the twisted pair part 14 according to the present invention. This is because the effect of increasing the center distance between them cannot be greatly expected.

In addition, when the inner end widths a1, b1, c1, and d1 are formed to be three times larger than the outer end widths a, b, c, and d, the overall thickness of the separator 20 is increased. Is too thick, resulting in a very high material consumption, as well as reduced cable flexibility, which leads to difficulty in laying.

Meanwhile, a penetrating portion (see FIGS. 5 and 6) extending in the longitudinal direction of the separator may be formed in the separator 20.

Here, the through part extending in the longitudinal direction of the separator 20 may be formed in various shapes such as a quadrangle 32, a circular 34, a cross 36.

Alternatively, as shown in Figs. 5 and 6, the cross-sectional shape of the penetrating portion has a surface slope substantially the same as the surface slope of the partition wall 22, that is, the cross-sectional shape substantially the same as the cross-sectional shape of the surface of the partition wall 22 ( 38, 39).

Here, almost the same means the same within an error range that can be generated in actual processing since it is practically impossible to form a penetration having exactly the same surface slope in actual processing.

As such, by forming the through part along the length direction of the separator 20, the amount of material required for manufacturing the separator 20 can be reduced while increasing the distance between the centers of the stranded parts 14. In addition, the flexibility of the separator 20 can be ensured.

On the other hand, at the portion where the partitions 22 meet each other, a border portion 29 formed of a surface slope Δy1 / Δx different from the surface slope Δy / Δx of two adjacent partitions may be additionally formed. have.

By forming the border portion 29 as described above, the center of the twisted pairs 14 with respect to the center O of the separator 20 is arranged radially more outward, the center of the twisted pairs 14 The effect of increasing the distance between them can be further increased.

2nd Example

The separator 20 (see FIG. 5) of the UTP cable according to the second embodiment of the present invention includes four partitions 22 and is characterized in that the surface slopes of the present partitions are gradually increased.

Here again, the surface slope is a unit facing the center O of the separator 20 from the outer end of the partition wall having a width (a, b, c, d) to the center O of the separator 20. The ratio of the width (Δy / Δx) to the length (Δx).

Therefore, the surface slope is configured to increase gradually, which means that the ratio of the increased width with respect to the unit length toward the center O of the separator 20 increases gradually, the width of the partition wall 22. It is shown to be configured to increase progressively toward the center of the separator 20.

As such, the width of the partition wall 22 is configured to increase progressively toward the center of the separator 20, so that the contact state between the conductive wire 12 and the separator 20 having a circular cross section is In addition, the conductive wire 12 having a smaller radius of curvature is in a state of being inscribed on the partition 22 surface of the separator 20 having a larger radius of curvature.

In the case of these two circular internal contact states, the contact stress is reduced than the circular and planar contact state, which increases the durability of the cable compared to the separator according to the prior art in which the circular conductor and the planar bulkhead are in contact. It means that the effect can be exerted.

Meanwhile, a penetrating portion (see FIGS. 5 and 6) extending in the longitudinal direction of the separator 20 may be formed inside the separator 20.

Here, the through part extending in the longitudinal direction of the separator 20 may be formed in various shapes such as a quadrangle 32, a circular 34, a cross 36.

Alternatively, as shown in Figs. 5 and 6, the cross-sectional shape of the penetrating portion has a surface slope almost equal to the surface slope of the partition wall, that is, formed into a cross-sectional shape 38 and 39 that is substantially the same as the cross-sectional shape of the partition wall surface. May be

Here, almost the same means the same within an error range that can be generated in actual processing since it is practically impossible to form a penetration having exactly the same surface slope in actual processing.

As such, by forming the through part along the length direction of the separator 20, the amount of material required for manufacturing the separator 20 can be reduced while increasing the distance between the centers of the stranded parts 14. In addition, the flexibility of the separator 20 can be ensured.

3rd Example

The separator 20 (see FIG. 6) of the UTP cable according to the third embodiment of the present invention includes four partitions 22, and is characterized in that the surface slopes of the partitions are gradually reduced.

Here, the surface slope means the center of the separator 20 from the outer end of the partition having the width (a, b, c, d) to the inner end having the width (a1, b1, c1, d1). The ratio of the width (Δy / Δx) increased with respect to the unit length (Δx) towards (O).

Therefore, the constant surface slope means that the ratio of the width increased with respect to the unit length toward the center O of the separator 20 gradually decreases, and the width of the partition wall is reduced by the separator 20. Although increasing toward the center of, the increasing ratio is gradually smaller means that it is configured to have an approximately truncated semi-elliptic cross section as shown in FIG.

Here, the outer end widths (a, b, c, d) and the inner end widths (a1, b1, c1, d1) of the partition wall included in the separator 20 are 1.2 × a ≦ a1 ≦ 3 × a, It is preferable to be comprised in the relationship of 1.2xb <= b1 <= 3xb, 1.2xc <= c1 <= 3xc, and 1.2xd <= d1 <= 3xd.

Here, when the inner end widths a1, b1, c1, and d1 are formed to be less than 1.2 times larger than the outer end widths a, b, c, and d, the twisted pair part 14 according to the present invention. This is because the effect of increasing the center distance between them cannot be greatly expected.

In addition, when the inner end widths a1, b1, c1, and d1 are formed to be three times larger than the outer end widths a, b, c, and d, the overall thickness of the separator 20 is increased. Is too thick, which not only increases material consumption excessively, but also reduces cable flexibility, which leads to difficulty in laying.

Meanwhile, a penetrating portion (see FIGS. 5 and 6) extending in the longitudinal direction of the separator may be formed in the separator 20.

Here, the through part extending in the longitudinal direction of the separator 20 may be formed in various shapes such as a quadrangle 32, a circular 34, a cross 36.

Alternatively, as shown in Figs. 5 and 6, the cross-sectional shape of the penetrating portion has a surface slope substantially the same as the surface slope of the partition wall 22, that is, the cross-sectional shape substantially the same as the cross-sectional shape of the partition wall surface 38, 39. It may be formed of).

Here, almost the same means the same within an error range that can be generated in actual processing since it is practically impossible to form a penetration having exactly the same surface slope in actual processing.

As such, by forming the through part along the length direction of the separator 20, the amount of material required for manufacturing the separator 20 can be reduced while increasing the distance between the centers of the stranded parts 14. In addition, the flexibility of the separator 20 can be ensured.

On the other hand, in the part where the partitions 22 meet each other, a border portion 29 formed of a surface slope Δy1 / Δx different from the surface slope Δy / Δx of two adjacent partitions may be additionally formed. have.

By forming the border portion 29 as described above, the center of the twisted pairs 14 with respect to the center O of the separator 20 is arranged radially more outward, the center of the twisted pairs 14 The effect of increasing the distance between them can be further increased.

As mentioned above, although the present invention has been described by way of limited embodiments and drawings, the technical idea of the present invention is not limited thereto, and a person having ordinary skill in the art to which the present invention pertains, Various modifications and variations may be made without departing from the scope of the appended claims.

Therefore, in Examples 1, 2, and 3, the surface slope of the partition wall included in each separator is constant or gradually increases or decreases, but the surface slope of each partition wall 22 included in one separator 20 is increased. Note that it is also possible to construct by selectively mixing two or more of the three surface gradients.

According to the present invention, it is possible to reduce the internal interference by increasing the distance between the center of the twisted pair included in the cable.

It is also possible to increase the distance between the centers of twisted pairs without the need for increasing the overall size of the separator or cable.

In addition, by forming the penetrating portion inside the separator, it is possible to reduce the material consumption required for manufacturing while increasing the distance between the center of the twisted pair.

In addition, the flexibility of the cable can be increased to provide ease of laying.
