Description
본 발명은 전파불감지역에서 이동전화 및 각종 무선통신을 위해 사용하는 누설동축케이블에 관한 것으로, 특히 케이블의 관경을 축소시켜 부품코스트의 절감과 함께 전송특성을 양호하게 하고 대량생산을 가능하게 하는 고기능 누설동축케이블에 관한 것이다.The present invention relates to a leaky coaxial cable used for mobile telephones and various wireless communications in a radio wave dead zone, and in particular, to reduce the diameter of the cable, to improve the transmission characteristics and the mass production, and to enable high-volume production. It relates to a leaky coaxial cable.
종래의 누설동축케이블은 도 1에 도시된 바와 같이 내부중심에 동관으로 된 내부도체(1)와 그 외부에 발포플라스틱 절연체(2)를 두고, 그 외부에 동 테이프를 종첨, 성형하여 동 테이프의 맞닿는 부분을 연속 용접한 다음, 다시 주름을 가공하여 외부도체(3)를 구성한 후 주름동관의 산 위치에 전파방사슬롯(4)을 밀접한 간격으로 절삭 가공한 다음 외피(5)를 피복하여서 구성된 것이다.In the conventional leaky coaxial cable, as shown in FIG. 1, an inner conductor 1 made of a copper tube at an inner center and a foamed plastic insulator 2 are disposed on an outer side thereof, and the copper tape is terminated and molded on the outside of the copper tape. Continuous welding of the abutting part, and then processing the corrugation again to form the outer conductor (3) and then cut the radioactive radiation slot (4) at a close interval at the acid position of the corrugated copper tube and then cover the outer shell (5). .
그러나 이는 동 테이프의 용접과 함께 주름가공시 외부도체(3)의 내구력을 유지하기 위하여 일정두께 이상(0.3㎜)의 소재를 사용하여야 하므로 부품코스트가 높아지며, 전파방사슬롯(4)이 밀접한 간격으로 구성되어 고밀도의 전자계가 외부로 방사됨에 따라 사용장소에서 케이블 주위의 근접구조물에 의하여 전자계가 혼란되어 전송특성이 큰 폭으로 변화되는 사례가 많을 뿐 아니라 가공 공정이 매우 복잡하여 대량생산이 곤란해짐에 따라 가공비가 비싸게 되는 문제점이 있다.However, it is necessary to use a material of a certain thickness or more (0.3 mm) in order to maintain the durability of the outer conductor 3 during the corrugation processing together with the welding of the copper tape. As the high-density electromagnetic field is radiated to the outside, the electromagnetic field is confused by the adjacent structure around the cable at the place of use, so that the transmission characteristics are greatly changed, and the manufacturing process is very complicated, which makes mass production difficult. Therefore, there is a problem that the processing cost becomes expensive.

It is an object of the present invention to provide a high-performance leaky coaxial cable that enables the weight reduction and miniaturization of the cable while maintaining the function, and the remarkable improvement of the transmission characteristics by applying the long period radiation slot.

도 2에 도시된 바와 같이 연동선, 동복 알루미늄선, 동관 중 선택되는 내부도체(10)와, 그 외부로부터 플라스틱 개재물을 횡권한 후 튜브 상으로 압출한 공기 및 플라스틱 복합절연물과 발포플라스틱 중 선택되는 절연체(20)를 구성하고, 주기적인 방사슬롯(40)이 천공된 두께 약 0.25㎜ 이하의 라미네이트형 동 테이프를 종첨하여서 된 외부도체(30)에 플라스틱재의 외피(50)를 피복시켜서 구성한 것이다.As shown in FIG. 2, the inner conductor 10 selected from the copper wire, the copper-clad aluminum wire, and the copper pipe, and the air and plastic composite insulation and foamed plastic extruded onto the tube after transversely winding the plastic inclusion from the outside thereof. The insulator 20 is formed, and the outer conductor 30 formed by covering a laminated copper tape having a thickness of about 0.25 mm or less having a perforated periodic spinning slot 40 is coated on the outer shell 30 of the plastic material.
특히 외부도체(30)인 동 테이프상에는 케이블에 공급된 신호에너지의 일부를 외부로 방사시켜 케이블 주위에 전자계를 형성시킴으로써 무선통화를 가능하게 하는 방사슬롯(40)이 일정간격으로 가공되어 있으며, 동 테이프의 바깥면에는 접착성 플라스틱이 코팅되어 있어 외부도체(30)와 외부피복 사이 및 중첩부 테이프 사이의 접착성을 부여해 주도록 되어 있다.In particular, on the copper tape, which is the outer conductor 30, a radiation slot 40 for radio communication by processing a part of the signal energy supplied to the cable to form an electromagnetic field around the cable is processed at regular intervals. Adhesive tape is coated on the outer surface of the tape to provide adhesiveness between the outer conductor 30 and the outer coating and between the overlapping tape.
도 3의 경우에는 외부도체(30)에 자기지지형 강(연)선(60)을 케이블심과 평행한 상태로 놓고 동시에 8자형 피복한 누설동축케이블을 구성한 것이다.In the case of FIG. 3, the self-supporting steel wire 60 is placed on the outer conductor 30 in parallel with the cable core, and at the same time, an 8-shaped sheathed coaxial cable is constructed.
도 4는 절연체(20) 위에 주기적인 방사슬롯(40)이 천공된 두께 약 0.2㎜ 이하의 알루미늄 테이프를 중첩되게 종첨시킨 외부도체(30)에 외피(50)를 피복시켜 구성한 것이고, 도 5는 도 4의 외부도체(30)에 자기지지형 강(연)선(60)을 케이블심과 평행한 상태로 놓고 동시에 8자형 피복한 누설동축케이블을 구성한 것이다.FIG. 4 is constructed by covering the sheath 50 with an outer conductor 30 in which an aluminum tape having a thickness of about 0.2 mm or less, in which a periodic spinning slot 40 is punched on the insulator 20, is superimposed. A self-supporting steel wire 60 is placed on the outer conductor 30 of FIG. 4 in parallel with the cable core, and at the same time, a leaky coaxial cable having 8-shaped sheaths is formed.
상기와 같이 구성된 본 발명은 지하철, 지하상가, 도로 터널 및 빌딩 내부 등과 같이 전파가 미치지 못하는 지하생활권에 설치되어 방사계의 전파를 누설시킴으로서 지상과 똑같은 전파환경을 만드는 누설동축케이블의 역할을 종래의 것보다 훨씬 효과적으로 수행하는 것이 가능하며 작동 상에 있어서도 다음과 같은 우수성이 입증되었다고 할 수 있다.The present invention configured as described above is installed in an underground living area where radio waves do not reach, such as subway, underground malls, road tunnels, buildings, etc., by leaking radio waves of the radioactive system, which plays a role of a leaky coaxial cable that creates a radio wave environment identical to the ground. It is possible to perform much more effectively than this, and the following excellence has been proved in the operation.
일반 동축케이블에서와 같이 내부도체(10)와 절연체(20)는 적은 손실로써 전기신호에너지를 전달하는 도체와 유전체, 그리고 케이블 내,외부도체간을 절연하는 절연체로서 작용하며, 외부도체(30)는 전기신호에너지를 제한된 원통형의 내부에 봉입된 채 축방향으로 전파되도록 해 주는 역할을 하게 된다.As in the coaxial cable, the inner conductor 10 and the insulator 20 serve as an insulator for insulating the conductor and the dielectric and the inner and outer conductors of the electrical signal energy with little loss, and the outer conductor 30. The electric signal energy is enclosed in the limited cylindrical interior and serves to propagate in the axial direction.
본 발명품의 외부도체(30)는 종래보다 두께가 얇은 동 테이프를 사용하였으나 동축케이블에는 높은 주파수의 신호가 전송됨에 따른 표피효과 영향으로 인하여 감쇄량이 같은 중요한 전기적 특성이 저하되는 일이 없고, 또한 동 테이프와 외부피복을 상호 접착시켜줌으로써 외부도체(30)에 주름을 가공하지 않더라도 외피(50)의 유연성 향상이 가능해짐에 따라 케이블의 경량화와 소형화가 가능해지는 것이다.The outer conductor 30 of the present invention uses a thinner copper tape than the prior art, but the coaxial cable does not deteriorate important electrical characteristics such as attenuation due to the effect of skin effect due to the transmission of a high frequency signal. By adhering the tape and the outer coating to each other, the flexibility of the outer shell 50 can be improved even if the outer conductor 30 is not wrinkled, thereby making it possible to reduce the weight and size of the cable.
특히 외부도체(30)에 적용된 방사슬롯(40)은 지향성이 강한 방사파계의 전자계를 외부로 방사하는 장주기 슬롯 안테나 배열을 취하고 있으며, 이에 따라 종래의 표면파계나 또는 지그재그 형태의 슬롯 형태와는 달리 케이블 근접구조물에 의하여 선로 주위의 전자계가 혼란되어 전송특성이 큰 폭으로 변화하는 현상이 없이 광대역에 걸쳐 전파방사가 가능해지므로 매우 우수한 전기적 특성을 보유하는 것이 가능해지고, 이에 따라 이동전화를 비롯한 모든 무선분야에 있어서 통신장애를 해소할 수 있는 고기능성 누설동축케이블의 제공이 가능하게 되는 것이다.In particular, the radiation slot 40 applied to the outer conductor 30 has a long-period slot antenna array for radiating the electromagnetic field of the directional radio wave system to the outside. Thus, unlike the conventional surface wave system or a zigzag slot form Due to the proximity structure of the cable, the electromagnetic field around the line is disrupted and radio waves can be radiated over a wide range without a significant change in transmission characteristics. Therefore, it is possible to possess very excellent electrical characteristics. In the field it is possible to provide a high-performance leaky coaxial cable that can solve the communication failure.
이상에서 설명한 바와 같이 본 발명은 0.25㎜ 이하의 초박판 동 테이프(또는 알루미늄 테이프)를 기본소재로 하여 한 면에 접착성 플라스틱을 코팅하고 고안된 형태의 방사슬롯을 가공하여 만든 슬롯천공 비주름형 라미네이트 동 테이프를 외부도체로 사용함으로서 다음과 같은 효과를 얻게 된다.As described above, the present invention is a slotted non-wrinkled laminate made by coating an adhesive plastic on one side with an ultra-thin copper tape (or aluminum tape) of 0.25 mm or less as a base material and processing a spinning slot of a designed shape. By using copper tape as an external conductor, the following effects are obtained.
첫째, 박판 테이프 사용을 통하여 경량화와 자원의 효율적 사용이 가능해짐과 동시에 부품코스트가 종래에 비하여 1/2로 감축되는 효과가 있다.First, it is possible to reduce the weight and the efficient use of resources through the use of thin tapes, and at the same time, the cost of parts is reduced to 1/2 compared to the conventional art.
둘째, 접착성 플라스틱의 단면코팅을 통하여 외부도체와 외부피복간 및 테이프 중첩부에서 테이프 상호간 접착성을 부여해 줌으로써 케이블의 굴곡특성이 향상되고, 외피 손상시 케이블 내부의 습기가 침투하는 것을 막아주어 전기적 특성 저하를 해결할 수 있다.Second, through the cross-sectional coating of adhesive plastics, the flexural properties of the cable are improved by providing adhesiveness between the outer conductor and the outer covering and the tape overlapping portion, and the moisture inside the cable is prevented from being penetrated when the outer skin is damaged. Deterioration of characteristics can be solved.
셋째, 외부도체상에 주름가공이 생략됨으로써 케이블의 외경축소가 가능해진다.Third, the outer diameter of the cable can be reduced by eliminating wrinkle processing on the outer conductor.
넷째, 새롭게 고안된 장주기 방사슬롯의 적용을 통하여 근접구조물에 의한 간섭의 영향으로 신호레벨이 저하되는 문제를 해결할 수 있다.Fourth, it is possible to solve the problem that the signal level is lowered by the influence of the interference by the adjacent structure through the application of the newly designed long period radiation slot.
다섯째, 위와 같은 슬롯천공 비주름형 라미네이트 동 테이프의 사용에 따라 종래의 작업공정에 비하여 공정이 단순화되고 대량생산이 용이해진다.Fifth, according to the use of the above-mentioned slotted non-wrinkled laminated copper tape, the process is simplified and mass production is easy as compared with the conventional working process.
