Abstract

A communication cable according to the present invention comprises: a core portion including a plurality of twisted wire portions that are each formed of a pair of insulation-clad conductive wires that are twisted; a separator for separating the plurality of twisted wire portions included in the core portion from one another; a non-continuous shielding tape covering the core portion; and a sheath portion covering the outside of the non-continuous shielding tape. The non-continuous shielding tape includes a conductive metal layer and a non-conductive synthetic resin layer. The conductive metal layer is formed stacked on the non-conductive synthetic resin layer. The non-continuous shielding tape includes: a continuous portion in which the conductive metal layer is continuously formed on the non-conductive synthetic resin layer; and a discontinuous portion in which the conductive metal layer is discontinued between one continuous portion and an adjacent continuous portion. The continuous portion is characterized by being formed within a range of 1 m to 5 m. According to the present invention, return loss can be reduced while external field interference between adjacent cables can be prevented. Also, the non-continuous shielding tape can be prevented from being easily broken by an externally applied stretching force, and a communication cable having high formability can easily be manufactured.

Description

비연속차폐테이프를 포함하는 통신케이블 및 비연속차폐테이프Communication cable and non-continuous shielding tape including non-continuous shielding tape
본 발명은 비연속차폐테이프를 포함하는 통신케이블 및 비연속차폐테이프에 관한 발명으로서, 보다 상세하게는 인접하는 케이블간의 외계간섭을 방지하면서 반사손실을 감소시키도록 구성되는 통신케이블 및 비연속 차폐테이프에 관한 발명이다.The present invention relates to a communication cable and a non-continuous shielding tape including a discontinuous shielding tape, and more particularly, a communication cable and a discontinuous shielding tape configured to reduce reflection loss while preventing external interference between adjacent cables. The invention relates to.
일반적으로 통신용 케이블로서 이용되는 UTP 케이블(또는 LAN 케이블)은, 구리 등의 도체를 절연체로 피복하여 구성된 도선들을 나선형으로 꼬아 연선부를 만들고, 이러한 개개의 연선부들을 4개 모아 코어부를 형성한 상태에서 피복한 형태로 구성되어 비차폐 페어케이블로도 불린다.In general, a UTP cable (or LAN cable), which is used as a communication cable, spirally twists conductive wires formed by covering a conductor such as copper with an insulator to form a stranded wire part, and gathers four individual twisted wire parts to form a core part. It is composed of sheathed form and is also called unshielded pair cable.
이러한 UTP 케이블은 최근 ATM 및 Ethernet 등 정보통신 기술의 발달에 따라 그 정보 전송능력 증대가 중요한 문제로 부각되고 있으며, 이러한 전송능력 증대를 구현하는 방향으로 개발 보완되어 왔다.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.
한편, 세계적인 규약에 의해 상기 UTP 케이블은 신호전송능력에 따라 카테고리(Category 또는 Cat.)라는 식별기호와 숫자에 의해 구분되며, 상기 숫자가 커질수록 높은 전송특성을 가진다. 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.
예를 들면, Cat.5 등급의 통신케이블은 100MHz의 신호 전송 대역으로 100 Mbps 의 전송속도를 가지며, Cat.6 등급의 통신케이블은 250 MHz 의 전송대역과 1 Gbps 의 전송속도를 가지고, Cat.6A 등급의 통신 케이블은 500 MHz 의 전송대역과 10 Gbps 의 전송속도를 가진다.For example, Cat.5 communication cable has a transmission rate of 100 Mbps with a 100 MHz signal transmission band, and a Cat.6 communication cable has a transmission rate of 250 MHz and a transmission rate of 1 Gbps. The 6A class communication cable has a transmission band of 500 MHz and a transmission rate of 10 Gbps.
상기와 같은 Cat.6A 등급의 통신 케이블은 케이블에 포함되는 연선부들간의 크로스토크 이외에도 인접한 통신 케이블 간의 크로스토크가 통신 케이블의 데이터 전달 특성을 결정하는 중요한 요인이 된다. In addition to the crosstalk between twisted pairs included in the cable, the Cat.6A-class communication cable is an important factor in determining the data transfer characteristics of the communication cable.
즉, 인접한 케이블 간의 크로스토크를 적절히 감소시키지 못할 경우에는 표준 규격에서 요구되는 전기적 특성들을 만족시키지 못하고, 그 등급에서 요구되는 안정적인 통신 품질을 확보할 수 없다.That is, if the crosstalk between adjacent cables is not adequately reduced, the electrical characteristics required by the standard specification are not satisfied, and stable communication quality required by the grade cannot be secured.
이를 해결하기 위한 방법으로서, 미국특허등록번호 7238886 호에서는 인접하는 케이블 내에 배치되는 연선부 간의 거리를 이격시키기 위해 시스부에 채널공간을 형성하는 방법이 제안되었으나, 이러한 방법에 의할 경우 케이블 전체의 외경이 증가되어 동일한 공간 내에 설치될 수 있는 케이블 수를 제한하는 요인이 된다.As a method for solving this problem, US Patent No. 7238886 proposes a method of forming a channel space in the sheath in order to space the distance between strands arranged in adjacent cables. The outer diameter is increased, which limits the number of cables that can be installed in the same space.
한편, 인접하는 케이블 간의 크로스토크를 감소시키기 위한 또 다른 방법으로서, 일본공개특허번호 2006-032193 호에서는 연선부의 외부를 금속 차폐테이프로 감싸는 방법을 제시하고 있으나, 이러한 방법에 의할 경우 일정한 길이의 케이블에 대해 상기 차폐테이프를 통해 전달되는 전자기파를 접시시키기 위한 접지 커넥터가 요구된다.On the other hand, as another method for reducing crosstalk between adjacent cables, Japanese Patent Laid-Open No. 2006-032193 proposes a method of wrapping the outside of the stranded wire with a metal shielding tape, but according to this method There is a need for a grounding connector for dishing electromagnetic waves transmitted through the shielding tape for a cable.
따라서, 인접한 케이블 간의 크로스토크를 감소시키면서도 케이블을 통한 데이터 전달 시 반사손실을 감소시킬 수 있도록 구성되는 통신용 케이블의 개발이 절실히 요구된다.Therefore, there is an urgent need for the development of a communication cable configured to reduce return loss in data transmission through the cable while reducing crosstalk between adjacent cables.
본 발명의 목적은, 인접하는 케이블 간의 외계간섭을 방지하면서도 반사손실을 감소시키도록 구성되는 비연속차폐테이프를 포함하는 통신케이블 및 비연속차폐테이프를 제공하는 것이다.It is an object of the present invention to provide a communication cable and a discontinuous shielding tape comprising a discontinuous shielding tape configured to reduce reflection loss while preventing external interference between adjacent cables.

본 발명에 따른 통신케이블은, 절연 피복된 한쌍의 도선이 꼬여짐으로써 형성되는 연선부를 복수 개 포함하는 코어부(10)와, 상기 코어부(10)에 포함되는 복수의 연선부를 서로 이격시키기 위한 세퍼레이터(20)와, 상기 코어부(10)를 감싸는 비연속차폐테이프(30)와, 상기 비연속차폐테이프(30)의 외부를 감싸는 시스부(40)를 포함하는 통신케이블로서, 상기 비연속차폐테이프(30)는 전도성금속층(36)과 비전도성 합성수지재층(32)을 포함하되, 상기 전도성금속층(36)이 상기 비전도성합성수지재층(32) 위에 적층 형성되고, 상기 비연속차폐테이프(30)는 상기 비전도성합성수지재층(32)에서 상기 전도성금속층(36)이 연속적으로 형성되는 연속부(36)와 인접하는 연속부(36)와 연속부(36) 사이에서 상기 전도성 금속층이 단절되는 불연속부(33)를 포함하며, 상기 연속부(36)는 1 m 내지 5 m 의 범위로 형성되는 것을 특징으로 한다.The communication cable according to the present invention includes a core portion 10 including a plurality of stranded portions formed by twisting a pair of insulated coated wires, and a plurality of stranded portions included in the core portion 10 to be spaced apart from each other.

상기 도선은 전기적 신호로 변환된 데이터의 전송을 위해, 구리와 같은 도체를 이용하여 선재(線材)로 형성한 후 절연체로 피복함으로써 형성된다.The conductive wire is formed by forming a wire rod using a conductor such as copper and then covering it with an insulator for transmission of data converted into an electrical signal.
상기 절연체는 난연 특성의 고분자인 LSZH(Low Smoke Zero Halogen)에 안정적인 가공 특성을 부여하기 위한 첨가제를 첨가함으로써 구성된다.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.
상기 연선부는 상기 도선을 일정한 간격의 대연피치로 복수 개 꼬아 형성되며, 통상적으로는 도 1 에 도시된 바와 같이, 두 가닥의 전선이 꼬여져 형성되지만 이에 한정되는 것은 아니며 다양한 변형 실시가 가능하다.The twisted wire portion is formed by twisting a plurality of conductor wires at a large pitch at regular intervals, and as shown in FIG. 1, two stranded wires are twisted, but not limited thereto.
또한, 상기 연선부는 차폐효과 증대를 통해 신호 간섭을 감소킴으로써 전송특성을 보다 향상시킬 수 있도록 상기 꼬여진 도선(연선부)의 외부를 피복한 구조로 구성될 수도 있다. In addition, the twisted pair may be configured to cover the outside of the twisted conductor (twisted pair) to further improve transmission characteristics by reducing signal interference through an increase in shielding effect.
상기 연선부는 고속 통신용 케이블에서 복수로 포함되며, 통상적으로는 도 1 에 도시된 바와 같이, 상기 시스부(40) 내에 4 개의 연선부가 포함되어 코어부(10)를 형성하지만, 이에 한정되는 것은 아니며 다양한 변형 실시가 가능하다.The twisted pair is included in a plurality of high-speed communication cable, and as shown in FIG. 1, four twisted pairs are included in the sheath portion 40 to form a core portion 10, but is not limited thereto. Various modifications are possible.
한편, 상기 케이블 내에 포함되는 각 연선부 간의 간섭을 억제하기 위해, 상기 각 연선부가 꼬여지는 대연피치는 서로 상이하게 형성된다.On the other hand, in order to suppress the interference between the twisted pairs included in the cable, the twisted pitch twisted each twisted pair is formed different from each other.
상기와 같이 복수 개로 포함된 연선부는 그 전체가 상기 케이블의 길이방향으로 소정의 피치를 가지고 꼬여진다.As described above, the twisted pair included in plurality is twisted with a predetermined pitch in the longitudinal direction of the cable.
또한, 본 발명에 따른 통신 케이블은 상기 코어부(10) 내의 복수의 연선부들을 서로 이격시키기 위한 세퍼레이터(20)를 포함한다. In addition, the communication cable according to the present invention includes a separator 20 for separating the plurality of twisted pairs in the core portion 10 from each other.
상기 세퍼레이터(20)는 그 단면구조가 십자형으로서, 상기 연선부 간의 내부 간섭을 방지하기 위해 상기 연선부들 사이를 가로막도록 상호 교차하는 격벽들을 포함하며, 상기 격벽들 사이에 형성된 공간에 상기 연선부들을 하나씩 수용하게 된다. The separator 20 has a cross-sectional structure having a cross shape and includes barrier ribs intersecting with each other so as to intersect the strand strands to prevent internal interference between the stranded portions, and the stranded portions are formed in a space formed between the barrier ribs. It will accept one by one.
또한, 상기 케이블은 상기와 같은 코어부(10)를 감싸며 외관을 형성하도록 구성된 시스부(40)를 포함한다.In addition, the cable includes a sheath portion 40 configured to surround the core portion 10 as described above and form an appearance.
여기서, 상기 시스부(40)는 케이블 내의 구성들을 기계적으로 보호할 뿐만 아니라, 인접하는 타 케이블이나 기타 전자장비로부터 발생 되는 전자기파에 의한 외계 간섭(Alien Crosstalk)을 차단하는 역할을 제공한다.Here, the sheath unit 40 not only mechanically protects the components in the cable, but also serves to block alien crosstalk caused by electromagnetic waves generated from other adjacent cables or other electronic equipment.
일반적으로, 상기 시스부(40)는 폴리에틸렌, PVC, 또는 올레핀(Olefin)계 고분자 물질 등의 절연성 물질로 형성된다. In general, the sheath portion 40 is formed of an insulating material such as polyethylene, PVC, or an olefin-based polymer material.
상기 코어부(10)와 시스부(40) 사이에는 상기 코어부(10)를 감싸는 비연속차폐테이프(30)가 배치된다.A discontinuous shielding tape 30 surrounding the core part 10 is disposed between the core part 10 and the sheath part 40.
상기 비연속차폐테이프(30)는 피이티(PET: Polyethylene Terephthalate) 재질 등의 비전도성합성수지재층(32) 위에 알루미늄 또는 알루미늄합금과 같은 전도성금속층(36)이 적층되어 형성된다.The discontinuous shielding tape 30 is formed by stacking a conductive metal layer 36 such as aluminum or an aluminum alloy on a non-conductive synthetic resin material layer 32 such as polyethylene terephthalate (PET) material.
여기서, 상기 비연속차폐테이프(30)는 상기 비전도성합성수지재층(32)에 적층되는 상기 전도성금속층(36)이 불연속적으로 형성되며, 따라서 상기 전도성금속층(36)이 일정 길이(L) 연속적으로 형성되는 연속부(36)와 인접하는 연속부(36)와 연속부(36) 사이에서 상기 전도성금속층이 단절되는 영역인 불연속부(33)를 포함한다.In this case, the non-continuous shielding tape 30 has the conductive metal layer 36 stacked on the non-conductive synthetic resin layer 32 discontinuously formed, and thus the conductive metal layer 36 is continuously of a predetermined length (L). And a discontinuity portion 33 which is an area where the conductive metal layer is disconnected between the continuous portion 36 and the adjacent continuous portion 36 and the continuous portion 36 formed.
상기 불연속부(33)에는 상기 전도성금속층(36)이 배치되지 않을 뿐이며, 상기 비전도성합성수지재층(32)은 존재하므로 전체적으로 비연속차폐테이프(30)는 긴 띠와 같은 형상의 비전도성합성수지재층(32) 위에 불연속적으로 전도성금속층(36)이 적층 배치된 형태로 형성된다.The conductive metal layer 36 is not disposed on the discontinuous portion 33, and the non-conductive synthetic resin layer 32 is present, so that the non-continuous shielding tape 30 has a non-conductive synthetic resin layer having a long band-like shape. The conductive metal layer 36 is formed in a stacked arrangement on the discontinuous layer 32.
도 2 를 참조하여, 상기 비연속차폐테이프(30)의 형성 방법을 살펴보면, 비전도성합성수지재층(32) 위에 전도성금속층(36)이 겹쳐진 상태에서 상기 전도성금속층(36)에 경사지게 형성되는 불연속부(33)를 형성하고, 상기 비전도성합성수지재층(32)과 전도성금속층(36)을 수직 방향으로 절단하면 도 3 에 도시되는 바와 같은 비연속차폐테이프(30)가 형성된다. Referring to Figure 2, looking at the method of forming the discontinuous shielding tape 30, the discontinuous portion is formed to be inclined to the conductive metal layer 36 in a state in which the conductive metal layer 36 is superimposed on the non-conductive synthetic resin material layer 32 ( 33), and the non-conductive synthetic resin material layer 32 and the conductive metal layer 36 are cut in the vertical direction to form a discontinuous shielding tape 30 as shown in FIG.
여기서, 상기 연속부(36)는 1 m 내지 5 m 의 범위로 형성된다.Here, the continuous portion 36 is formed in the range of 1 m to 5 m.
상기 연속부(36)의 길이(L)는 불연속부(33)가 발생하는 주기이며, 불연속부(33)에서는 케이블 코어부(10) 외부에 차폐가 없는 구조이므로, 임피던스 변화가 발생하게 된다.The length L of the continuous part 36 is a period in which the discontinuous part 33 is generated, and in the discontinuous part 33, since there is no shielding outside the cable core part 10, impedance change occurs.
임피던스 변화가 발생하는 주파수는 간단한 전파속도 수식인 v = f(주파수) X λ(파장) 에 의해 계산이 가능하다.The frequency at which impedance changes occur can be calculated using the simple propagation velocity equation: v = f (frequency) X λ (wavelength).
일반적으로 케이블의 전파속도는 2/3 X C (C 는 빛의 속도)로 고려되므로, λ 는 불연속부가 발생하는 주기로서 아래와 같은 값이 도출된다.In general, the propagation speed of the cable is considered to be 2/3 X C (C is the speed of light), and λ is the period in which discontinuities occur.

만약, 상기 연속부(36)의 길이 L 이 1 m 미만으로 형성될 경우에는, 불연속부(33) 발생 횟수가 증가하여 임피던스 변화 강도가 누적되어 증가하게 된다. If the length L of the continuous part 36 is formed to be less than 1 m, the number of occurrences of the discontinuous part 33 increases, and the impedance change intensity accumulates and increases.
임피던스 변화가 증가하는 경우 해당 주파수에서 반사파가 발생되므로, 이에 의한 반사손실(Return Loss)이 급격히 증가되게 된다.When the impedance change increases, the reflected wave is generated at the corresponding frequency, so that the return loss is rapidly increased.
참고로, 반사손실은 임피던스에서 계산되는 값으로서 수식은 아래와 같다.For reference, return loss is a value calculated from impedance, and the formula is as follows.
RL = 20 Log[(Z - 100)/(Z + 100)], Z 는 임피던스로서, Z 값이 100 ohm 에서 변화될 수록 반사손실 값이 증가하게 된다.RL = 20 Log [(Z-100) / (Z + 100)], Z is the impedance, and the return loss increases as the Z value changes from 100 ohms.
또한, 길이 L 이 짧아지는 경우 상기 불연속부(33)를 형성하는 작업이 많아져 전체 비연속차폐테이프(30)의 생산 비용이 증대되는 문제점이 있다.In addition, when the length L is shortened, there is a problem in that the number of operations for forming the discontinuous portion 33 increases, thereby increasing the production cost of the entire discontinuous shielding tape 30.
상기 연속부(36)의 L 값을 결정하기 위한 추가적인 요소(Factor)는 국제 표준(TIA or IEC Standard)에서 요구하는 케이블 사양이다.An additional factor for determining the L value of the continuous part 36 is the cable specification required by the International Standard (TIA or IEC Standard).
국제 표준사양을 기준으로 한 반사손실의 요구 Spec. 은 하기와 같다.Requirements for return loss based on international standard specifications. Is as follows.
1 ~ 10 MHz: -20 + 5 Log(f) dB1 to 10 MHz: -20 + 5 Log (f) dB
10 ~ 20 MHz: 25 dB10 to 20 MHz: 25 dB
20 MHz 이상: 25 - 7 X Log(f/20)dB20 MHz or more: 25-7 X Log (f / 20) dB
상기와 같은 요구사항을 임피던스 변화 발생 주기에 해당하는 주파수에 적용하면 아래와 같다.Applying the above requirements to the frequency corresponding to the impedance change period is as follows.

20 MHz 이상의 주파수에서는 요구사양이 낮아지므로, 상대적으로 규격 만족이 용이하다.At frequencies above 20 MHz, the requirements are lower, making it easier to meet specifications.
단, 200 MHz 이상으로 증가되는 경우 규격 요구사항은 낮아지지만, 임피던스 변화 강도가 증가하여 반사손실의 peak 가 증가되므로, 국제 요구사항 만족이 가능한 수준에서 L 값이 선정되어야 한다.However, if it is increased above 200 MHz, the standard requirement is low, but the peak of return loss is increased by increasing the intensity of impedance change, so L value should be selected at the level that can satisfy international requirements.
상기 실험결과 1 m 이상 L 값에서 특성 만족이 가능함을 확인하였다.As a result of the experiment, it was confirmed that characteristic satisfaction was possible at an L value of 1 m or more.
또한, 상기 연속부(36)의 길이 L 이 5 m 를 초과할 경우에는 반사손실의 margin 이 다시 증가하게 되지만, 상기 연속부(35)의 길이가 지나치게 길여져 상기 연속부(36)를 따라 전달되는 전자기파를 접지시키기 위한 차폐커넥터와 전체 시스템이 접지 가능한 형태로 설치 및 사용되어야 하므로, 비용이 현저히 증가되고 설치 과정이 번거롭게 된다.In addition, when the length L of the continuous part 36 exceeds 5 m, the margin of the reflection loss increases again, but the length of the continuous part 35 becomes too long and is transmitted along the continuous part 36. Since the shielding connector and the whole system must be installed and used in a groundable form to ground the electromagnetic waves, the cost is significantly increased and the installation process is cumbersome.
한편, 상기 불연속부(33)의 폭(D)은 0.5 mm 내지 5 mm 사이의 범위로 형성된다.On the other hand, the width (D) of the discontinuous portion 33 is formed in a range between 0.5 mm to 5 mm.
여기서, 상기 불연속부(33)의 폭(D)이 0.5 mm 이하일 경우, 전체 비연속차폐테이프(30) 제조가 매우 어려워지며, 만약 상기 불연속부(33)의 폭(D)이 5 mm 를 초과할 경우에는 인접하는 케이블 간의 외계간섭(Alien Crosstalk)을 차폐하는 효과를 충분히 발휘할 수 없다.Here, when the width D of the discontinuous portion 33 is 0.5 mm or less, it becomes very difficult to manufacture the entire discontinuous shielding tape 30, and if the width D of the discontinuous portion 33 exceeds 5 mm In this case, the effect of shielding alien crosstalk between adjacent cables cannot be sufficiently exerted.
이러한 견지에서, 상기 불연속부(33)의 폭(D)에 대한 상기 연속부(36)의 길이(L) 비율(L/D)은 200 내지 50000 으로 형성된다.In this respect, the ratio L / D of the length L of the continuous portion 36 to the width D of the discontinuous portion 33 is formed to be 200 to 50000.
한편, 상기 연속부(36)의 폭(W)은 20 mm 내지 25 mm 로 형성되어, 상기 비연속차폐케이블(30)이 상기 코어부(10)를 감싸는 경우 상기 폭(W) 중에서 3 mm 정도는 오버랩되어 상기 코어부(10)를 감싸므로써, 인접하는 케이블 간의 외계간섭(Alien Crosstalk)을 보다 확실히 차폐할 수 있도록 구성된다.On the other hand, the width (W) of the continuous portion 36 is formed from 20 mm to 25 mm, when the non-continuous shielding cable 30 surrounds the core portion 10 is about 3 mm of the width (W) Is overlapped to surround the core part 10, and is configured to more reliably shield alien crosstalk between adjacent cables.
상기 비전도성합성수지재층(32)의 두께(t1)는 0.01 mm 내지 0.05 mm 로 형성되고, 상기 전도성금속층(36)의 두께(t2)는 0.025 mm 내지 0.075 mm 범위로 형성된다.The thickness t1 of the nonconductive synthetic resin material layer 32 is formed to be 0.01 mm to 0.05 mm, and the thickness t2 of the conductive metal layer 36 is formed to be in a range of 0.025 mm to 0.075 mm.
여기서, 상기 비전도성합성수지재층(32)은 비록 도 4 에서 1 개 층이 형성되는 것으로 도시되었으나, 이에 한정되는 것은 아니며 2 개 이상의 합성수지재층으로 구성될 수도 있으며, 이 경우 전체 비전도성합성수지재층의 두께가 상기 범위로 형성된다.Here, although the non-conductive synthetic resin material layer 32 is illustrated as one layer is formed in FIG. 4, the non-conductive synthetic resin material layer 32 is not limited thereto and may be composed of two or more synthetic resin material layers, in which case the thickness of the entire non-conductive synthetic resin material layer Is formed in the above range.
또한, 상기 비연속차폐테이프(30)를 형성하는 경우에는 상기 전도성금속층(36)의 두께(t2)가 상기 비전도성합성수지재층(32)의 두께(t1)보다 크게 형성된다.In addition, when the non-continuous shielding tape 30 is formed, the thickness t2 of the conductive metal layer 36 is greater than the thickness t1 of the non-conductive synthetic resin material layer 32.
상기 비연속차폐테이프(30)를 상기 코어부(10)의 외부에 감싸는 경우, 알루미늄 또는 알루미늄합금으로 형성되는 상기 전도성금속층(36)은 감싸진 형태를 유지하는 반면, 피이티 재질 또는 기타 합성수지재로 형성되는 상기 비전도성합성수지재층(32)은 본래의 평평한 형태로 복귀하려는 스프링력을 발휘하게 된다.When the non-continuous shielding tape 30 is wrapped around the core portion 10, the conductive metal layer 36 formed of aluminum or aluminum alloy maintains a wrapped shape, while the PTI material or other synthetic resin material is maintained. The non-conductive synthetic resin material layer 32 is formed to exert a spring force to return to the original flat form.
따라서, 상기 전도성금속층(36)의 두께(t2)를 상기 비전도성합성수지재층(32)의 두께(t1)보다 크게 형성함으로써, 상기 비연속차폐테이프(30)로 코어부(10)를 감싸는 경우 추가적인 힘을 가하거나 공정을 수행하지 않아도 원형으로 감싸진 형태를 그대로 유지할 수 있다.Therefore, when the thickness t2 of the conductive metal layer 36 is formed to be larger than the thickness t1 of the non-conductive synthetic resin material layer 32, the case in which the core portion 10 is wrapped with the discontinuous shielding tape 30 is additional. The circular envelop can remain intact without any force or process.
한편, 도 2 및 3 에 도시되는 바와 같이, 상기 불연속부(33)는 상기 연속부(36)의 길이 방향에 대해 경사지게 형성되며, 이때 상기 불연속부(33)는 상기 연속부(36)의 길이(L) 방향에 대해 30도 내지 60도의 각도(θ)로 경사지게 형성될 수 있다.On the other hand, as shown in Figures 2 and 3, the discontinuous portion 33 is formed to be inclined with respect to the longitudinal direction of the continuous portion 36, wherein the discontinuous portion 33 is the length of the continuous portion 36 It may be inclined at an angle θ of 30 degrees to 60 degrees with respect to the (L) direction.
상기 비연속차폐테이프(30)에 대해 인장력이 가해질 경우에는 도 3 에 도시된 화살표와 같은 상태로 상기 불연속부(33)에 힘이 가해지는데, 만약 상기 불연속부(33)가 상기 비연속차폐테이프(30)의 길이 방향에 대해 수직한 방향으로 형성될 경우에는, 상기 비연속차폐테이프(30)의 폭(W)과 상기 비전도성합성수지재층(32)의 두께(t1)의 곱에 해당되는 면적(W X t1)의 비전도성합성수지재층 단면이 상기 인장력에 대해 저항하게 된다.When a tensile force is applied to the discontinuous shielding tape 30, a force is applied to the discontinuous portion 33 in the same state as the arrow shown in FIG. 3, if the discontinuous portion 33 is the discontinuous shielding tape. When formed in the direction perpendicular to the longitudinal direction of (30), the area corresponding to the product of the width (W) of the non-continuous shielding tape 30 and the thickness (t1) of the non-conductive synthetic resin material layer 32 The cross-section of the non-conductive synthetic resin material layer of (WX t1) is resistant to the tensile force.
그런데, 상기와 같이 불연속부(33)를 경사지게 형성할 경우에는, 상기 인장력에 대해 저항하는 수직단면에 전도성금속층이 포함되므로, 상기 인장력에 대해 저항하는 단면의 면적이 증가하게 되어 보다 큰 인장력에도 견딜 수 있게 된다.However, when the discontinuous portion 33 is formed to be inclined as described above, since the conductive metal layer is included in the vertical cross section resisting the tensile force, the area of the cross section resisting the tensile force is increased to withstand greater tensile force. It becomes possible.
상기와 같은 견지에서, 상기 경사지게 형성되는 각도 θ 는 30도 내지 60도의 범위에서 형성되며, 더욱 바람직하게는 대략 45도의 각도로 형성된다.In view of the above, the inclined angle θ is formed in the range of 30 to 60 degrees, more preferably at an angle of approximately 45 degrees.

도 5 내지 도 8과 아래의 표 3을 참고하는 경우, 본 발명에 따른 비연속차폐테이프(30)로 상기 코어부(10) 외부를 감싼 경우와 감싸지 않은 경우의 인접하는 케이블 간의 외계간섭 특성을 측정한 결과, 본 발명에 따른 차폐테이프로 감싸지 않을 경우, 첫번째 연선부(1 pair)의 외계간섭의 크기가 34.85 MHz 에서 -3.11 dB 의 특성을 보여, 실험된 종래의 Category 6A 등급의 UTP 케이블은 국제규격에서 요구하는 외계간섭과 관련된 스펙을 만족하지 못함을 확인할 수 있으며, 본 발명에 따른 비연속차폐테이프(30)를 적용한 경우는 Category 6A 등급의 UTP 케이블을 구성하는 4개의 패어 중 마진이 가장 작은 두번째 연선부(2 pair)에서 최소 마진이 7.7 dB 로서 안정적인 수준을 보여 Category 6A 등급의 UTP 케이블의 외계간섭과 관련된 국제 규격을 만족함을 확인할 수 있다.Referring to FIGS. 5 to 8 and Table 3 below, when the outer shielding tape 30 according to the present invention is wrapped around the outside of the core portion 10 and not wrapped around the interfering characteristics between the cable As a result of the measurement, when the shielding tape according to the present invention is not wrapped, the magnitude of the external interference of the first twisted pair (1 pair) shows a characteristic of -3.11 dB at 34.85 MHz. It can be confirmed that the specification related to the extraterrestrial interference required by the international standard is not satisfied. When the non-continuous shielding tape 30 according to the present invention is applied, the margin among the four pairs constituting the UTP cable of the Category 6A grade is the most. The minimum margin is 7.7 dB in the second small twisted pair (2 pairs), which confirms that it satisfies international standards related to extraterrestrial interference of Category 6A UTP cables.
또한, 비연속 차폐테이프가 적용되지 않은 종래 Category 6A 등급의 UTP 케이블의 경우, 4개 연선부 간 특성 차이는 10 dB 의 불규칙적인 차이(1pair VS 3 pair)를 보였으나, 본 발명에 따른 비연속 차폐테이프(30)를 적용한 경우 1.4 dB에 불과한 차이(1pair VS 2 pair)를 보여 연선별로 편차가 크지 않고 각 연선부가 상대적으로 균일한 특성을 가짐을 확인할 수 있다.In addition, in the case of the conventional Category 6A grade UTP cable to which the discontinuous shielding tape is not applied, the characteristic difference between the four twisted pairs showed an irregular difference (1 pair VS 3 pair) of 10 dB, but the discontinuous according to the present invention. When the shielding tape 30 is applied, the difference is only 1.4 dB (1 pair VS 2 pairs), and thus the variation of each strand is not large, and each strand has a relatively uniform characteristic.
이상, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명의 기술적 사상은 이러한 것에 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해, 본 발명의 기술적 사상과 하기 될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형 실시가 가능할 것이다.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.
