본 발명은 CATV 인입선용, MATV 배선용 및 옥내배선용으로 사용되는 동축케이블에 관한 것으로 특히, 인장 특성과 차폐 특성을 양호하게 함과 동시에 대량 생산이 용이하도록 된 것이다.The present invention relates to a coaxial cable used for CATV lead wire, MATV wiring, and indoor wiring, and in particular, to improve the tensile properties and shielding properties and to facilitate mass production.

먼저 종래의 동축케이블을 살펴보면 도면 제2도에서와 같이, 내부 중심에 연동선으로된 내부도체(100)와 그 외부에 충실 플라스틱 절연체(200)를 두고 그 외부에 주색도금된 연동선을 편조하여 외부도체(300)를 구성하여 외피(400)를 피복하여서 된 것이었다.Referring to the conventional coaxial cable, as shown in FIG. 2, the inner conductor 100 made of the interlocking line at the inner center and the faithful plastic insulator 200 are disposed on the outside thereof, and the inter-colored interlocking wire is braided on the outside. The outer conductor 300 was configured to cover the outer shell 400.

그러나 이는, 사용장소의 온도가 높은 경우 케이블 자체 중량에 비해 인장 특성이 양호치 못하므로 케이블이 늘어난 후 수축되지 않음에 따라 전기적 특성이 저하되고 케이블 수명이 단축되며, 늘어남에 대한 사후관리 즉, 재작업이 필요하게 되는 등의 문제점이 야기되는 것이며, 특히, 외부도체(300)의 구조가 연동선 재질의 편조인 관계로 케이블 중량이 커지며, 전파누설(불요방사파 누설) 및 전파혼입이 발생되고, 대량 생산이 곤란해짐에 따라 가공비가 높은 문제점이 있는 것이었다. 그리고, 사용 케이블의 규격을 축소하려해도 인장특성이 좋지 않으므로 제품의 규격축소에도 장애요인이 되는 것으로 불필요하게 굵은 동축케이블을 사용하고 있는 실정에 있는 것이었다.However, when the temperature of the place of use is high, the tensile property is not good compared to the weight of the cable itself. As the cable does not shrink after the cable is stretched, the electrical property is reduced and the cable life is shortened. Problems such as the need for work is caused, in particular, the weight of the cable is increased because the structure of the outer conductor 300 is braided of the interlocking wire material, radio wave leakage (irradiated radio wave leakage) and radio wave mixing occurs As the mass production becomes difficult, processing costs are high. In addition, even when attempting to reduce the size of the cable used, the tensile characteristics are not good, which is an obstacle to reducing the size of the product.

따라서, 본 발명은 이상과 같은 문제점을 해결하고자 인장 특성이 양호한 강선등에 도전성이 양호한 동, 알루미늄, 은 등을 도금한 선재를 내부도체로 하여 늘어남에 대한 강성을 부여함과 동시 케이블의 규격 축소가 가능하게 하여 케이블의 경량화 및 소형화를 가능케하고, 케이블 자체 중량을 감소시키고 전파의 누설 및 혼입 방지가 양호하도록 금속성 테이프와 금속선을 외부도체로 하여서 된 옥내배선용 동축케이블을 제공함에 그 목적이 있는 것이다.Therefore, in order to solve the problems described above, the present invention provides rigidity such as copper, aluminum, silver, etc., wired with good tensile properties to the inner conductor, thereby providing rigidity for stretching and reducing the size of the cable simultaneously. The purpose of the present invention is to provide a coaxial cable for indoor wiring using a metallic tape and a metal wire as an outer conductor to enable light weight and miniaturization of the cable, to reduce the weight of the cable itself, and to prevent leakage and mixing of radio waves.

이하에서 이를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, this will be described in detail with reference to the accompanying drawings.

중심부에 내부도체와 그 외부로 절연체와 외부도체 및 외피로 피복된 통상의 옥내배선용 동축케이블에 있어서, 동, 알루미늄, 은 중 어느 하나를 선택해서 도금된 동복강선, 동복스테인레스선, 알루미늄복강선, 은복강선 중 선택되는 내부도체(1)와, 그 외부로는 충실 플라스틱과 발포성 플라스틱중 선택되는 절연체(2)를 피복하고, 두께 0.1mm 이하의 도전성 금속테이프(31)를 횡권 또는 종첨하고 그 외부에 금속선(32)을 횡권 또는 종첨하여서 된 외부도체(3)에 외피(4)를 피복시켜서 된 것이다.In a typical indoor wiring coaxial cable coated with an inner conductor, an outer conductor, and an outer shell at the center thereof, a copper-clad steel wire, a copper-clad stainless steel wire, an aluminum-stranded wire, selected from copper, aluminum, and silver, The inner conductor 1 selected from the silver-clad steel wire and the outer insulator 2 selected from the solid plastic and the expandable plastic are covered, and the conductive metal tape 31 having a thickness of 0.1 mm or less is transversely wound or terminated and the outside thereof. The outer sheath 4 is coated with the outer conductor 3 formed by transverse winding or ending the metal wire 32.

이상과 같이 구성된 본 발명의 작용효과를 살펴보면 인장특성이 양호한 강선재등에 도전성이 양호한 동, 알루미늄, 은 등을 도금한 선재를 내부도체(1)로 사용하므로써 케이블의 규격을 축소하여 사용할 수 있으므로써 케이블의 경량화와 소형화가 가능해지는 것이며, 이때 전기적 특성의 저하를 막기 위해서는 절연체(2)를 도면 제2b도에서와 같이 고발포 플라스틱 절연을 하므로써 전기적 특성저하를 해결할 수 있다. 그리고, 외부도체(3)는 금속성테이프(31)와 금속선(32)을 횡권 또는 종첨하므로써 전파누설 및 혼입을 방지하는 차폐효과가 우수하며 종래 편조 방식에 비해 케이블의 대량 생산이 용이하게 되며, 포설시에도 기존의 편조형 동축케이블에서 사용하는 콘넥터를 사용하여 접속가능하고, 콘넥팅 방법 또한 기존방식과 동일하게 작업할 수 있는 것이다.Looking at the effect of the present invention configured as described above by reducing the size of the cable by using a wire plate coated with copper, aluminum, silver, etc. with good conductivity to the steel wire with good tensile properties as the inner conductor (1) It is possible to reduce the weight and the size of the cable, and in order to prevent the deterioration of the electrical characteristics, the electrical characteristics can be solved by high-insulation plastic insulation of the insulator 2 as shown in FIG. 2B. In addition, the outer conductor 3 has excellent shielding effect to prevent radio leakage and mixing by transversely or terminating the metallic tape 31 and the metal wire 32, and facilitates mass production of cables compared to the conventional braiding method. In the case of the existing braided coaxial cable can be connected using the connector, and the connection method can work the same way as the existing method.

이상과 같이 된 본 발명은 케이블 자체가 양호한 인장력을 가지게 되어 외기의 고온도에 따른 늘어남이 대폭 개선되어 종래의 이로인한 전기적 특성저하, 케이블 수명단축이 방지되고 케이블의 늘어남에 대한 사후관리가 필요없게 되며, 외부도체에 의해 전파누설 및 혼입이 방지되어 차폐 효과가 우수한 등으로 CATV 인입선, MATV 배선 및 기타용도의 옥내배선용 동축케이블로써 효과적인 것이다.The present invention as described above has a good tensile force of the cable itself is greatly improved the increase according to the high temperature of the outside air, thereby reducing the electrical characteristics due to the conventional, shortening the life of the cable and does not require the follow-up management of the extension of the cable It is effective as CATV lead wire, MATV wiring, and other indoor coaxial cable for CATV lead wire, MATV wiring, and other uses because it prevents radio leakage and mixing by external conductor.
