본 고안은 케이블의 단말접속시에 접속주변의 확실한 수밀구조를 확보하기 위하여, 이에 사용되는 접속재를 커넥터와 내부도체금구가 일체화된 고무몰드애관 빛 방수열수축커버로 구성한 가교폴리에틸렌케이블 접속재에 관한 것이다.The present invention relates to a crosslinked polyethylene cable connecting member composed of a rubber mold tube light waterproof heat shrink cover in which the connecting member is integrated with a connector and an inner conductor bracket in order to secure a reliable watertight structure around the connecting terminal when the cable is connected to the terminal.
일반적으로 케이블 접속재를 구성하는데 있어, 접속케이블이 외부의 전기적 충격이나 파괴 또는 부식으로부터 전기적 기계적으로 보호유지되고, 수분이나 이물질의 침입으로부터도 안정된 수밀성이 보장될 수 있도록 간단하고 신뢰성있는 케이블 접속재를 이룬다는 것이 상당히 어려운 작업이다.In general, in forming a cable connecting member, the connecting cable is electrically and mechanically protected from external electric shock, destruction or corrosion, and a simple and reliable cable connecting member is formed to ensure stable watertightness even from ingress of moisture or foreign substances. Is a fairly difficult task.
제 1 도는 종래의 가교폴리에틸렌케이블 접속재의 구조를 나타낸 것이며 그 구성을 살펴보면 다음과 같다.Figure 1 shows the structure of a conventional crosslinked polyethylene cable connecting member and looks at its configuration as follows.
접속할 케이블의 접속부를 최외부의 외피로부터 차례로 제거하여 절연체(12)가 노출되도록 하고, 케이블 접속부의 상단부는 절연체(12) 마저 제거하여 도체(10)를 노출하여 노출된 도체(10)를 공지된 연결수단과 방법에 의해 접속시킨 다음, 노출된 케이블의 절연체(12) 외면에 스트레스콘(22)을 기우고, 그 위를 다수의 절연환(20)을 적층삽입시킨 후에 평와셔(24)와 고무캡(26)을 끼워 결속고정하는데, 이때 상기 구성품들의 내면에는 충분한 실리콘 윤활방수유(34)가 도포되어 있다.The connecting portion of the cable to be connected is sequentially removed from the outermost shell so that the insulator 12 is exposed, and the upper end of the cable connecting portion is also removed from the insulator 12 to expose the conductor 10 to expose the exposed conductor 10. After connecting by the connecting means and the method, the stress cone 22 is inclined to the outer surface of the insulator 12 of the exposed cable, and a plurality of insulated rings 20 are stacked thereon, and then the flat washer 24 The rubber cap 26 is fitted and fastened to each other, and sufficient silicone lubricating oil 34 is applied to the inner surface of the components.
그리고 상기의 스트레스콘(22) 하부의 고정수단은 접지밴드(32)와 같은 공지의 수단으로 고정결합되었으며, 미설명부호 30은 케이블의 노출 도체를 인출결합하기 위한 커넥터이다.In addition, the fixing means under the stress cone 22 is fixedly coupled by a known means such as the ground band 32, and reference numeral 30 is a connector for drawing out the exposed conductor of the cable.
상기와 같은 접속수단에 의한 종래의 케이블 접속재는 절연체의 외경과 스트레스콘(22)이나 절연환(20)의 내경이 맞지 않을 경우 결속면 사이에 관통절연파괴가 발생하기 쉽고, 특히 다수를 적층 결합하여 절연 및 기계적 강도를 유지하는 절연환(20)은 케이블이 휘어지거나 악천후와 같은 자연환경으로부터 수밀성을 보호받기 어려워 실리콘 윤활방수유에 수분 침투로 인한 전기적 성능이 현격히 저하되며, 또한 케이블 접속재를 구성하는 과정이 복잡하여 조립시간이 길며, 조립시 이물질이 침투될 가능성이 많아 신뢰성이 떨어지는 문제점이 있었다.In the conventional cable connecting member by the connecting means as described above, when the outer diameter of the insulator and the inner diameter of the stress cone 22 or the insulating ring 20 do not match easily, breakthrough insulation easily occurs between the binding surfaces, and in particular, a plurality of laminated couplings Insulation ring 20 that maintains the insulation and mechanical strength is difficult to be protected from the water tightness from the natural environment, such as the cable is bent or bad weather, the electrical performance due to moisture penetration into the silicone lubricating waterproofing oil is significantly reduced, and also constitute a cable connection material The process is complicated, the assembly time is long, there is a problem that the foreign matter is likely to penetrate during assembly, the reliability is low.
따라서 본 발명은 이러한 문제점을 해결하고자 접속재의 구조를 노출된 케이블의 도체 위에 커넥터, 내부도체금구가 일체화된 고무몰드애관을 씌워 삽입한 후, 방수열수축커버를 입히는 것으로 구성하여 외부의 자연환경으로부터 신뢰성있는 수밀성을 보장받을 수 있도록 하고 있다.Therefore, in order to solve this problem, the structure of the connection member is inserted into the connector of the exposed cable, the rubber mold tube integrated with the inner conductor bracket on the exposed conductor of the cable, and then the waterproof heat shrink cover is configured to cover the reliability from the external natural environment It ensures that watertightness is guaranteed.
이하, 본 고안의 구조 및 작용효과를 첨부된 도면에 의하여 설명하면 다음과 같다.Hereinafter, the structure and the effect of the present invention will be described with reference to the accompanying drawings.
본 고안의 케이블 접속재는 제 2 도 및 제 3 도에 도시된 바와같이, 케이블의 노출 도체(10) 위에 커넥터(30), 내부도체금구(50)가 일체화 된 고무몰드애관(56)을 삽입한 후, 상기의 고무몰드애관(56) 위에 수밀코팅제(54)가 융착되어 있는 수밀코팅제입방수 열수축커버(52)를 삽착한다.In the cable connecting member of the present invention, as shown in FIGS. 2 and 3, a rubber molded conduit 56 in which a connector 30 and an inner conductor bracket 50 are integrated is inserted on an exposed conductor 10 of a cable. After that, the water-tight coating agent-coated waterproofing heat-shrink cover 52 in which the water-tight coating agent 54 is fused on the rubber molded conduit 56 is inserted.
케이블의 노출 도체(10)에 연결된 내부도체금구(50)를 고무몰드애관(56)에 삽입몰딩하는데 제 3 도에 상세히 도시된 바와 같이, 삽입할 내부도체금구(50)의 단부를 소정의 곡률반경(R)을 갖는 형상으로 삽입되어 있다.Insert molding of the inner conductor bracket 50 connected to the exposed conductor 10 of the cable into the rubber molded conduit 56, as shown in detail in FIG. 3, by the predetermined curvature of the end of the inner conductor bracket 50 to be inserted. It is inserted in the shape which has radius R. As shown in FIG.
즉, 케이블에 피복된 도체(10)와의 결속력을 양호하게 확보하도록 하기 위해서 커넥터(30)와 고무몰드애관(56)을 일체화한 것으로, 도체(10)의 단말부를 소정의 곡률반경(R)으로 하여 커넥터(30)가 인출 방향으로 힘을 받게 되더라도 그 접촉주변에서 강력하게 탄력적으로 고정지지하게 되므로 이탈됨이 없이 결속력이 강화되도록 되어 있다.That is, the connector 30 and the rubber mold tube 56 are integrated in order to ensure a good binding force with the conductor 10 coated on the cable, and the terminal portion of the conductor 10 has a predetermined radius of curvature R. Thus, even if the connector 30 receives the force in the drawing direction, it is strongly and elastically supported in the vicinity of the contact so that the binding force is strengthened without being separated.
또한 소정의 곡률반경(R)으로 처리된 내부도체금구(50)의 단부를 반도전 고무코팅처리하여 전기적 접촉에 신뢰성있는 절연성을 부여한다.In addition, semi-conductive rubber coating is applied to the end portion of the inner conductor bracket 50 treated with a predetermined radius of curvature R to provide reliable insulation to electrical contact.
상기의 고무몰드애관(56)은 고무사출기나 고무프레스로 제작이 가능하다.The rubber mold tube 56 may be manufactured by a rubber injection machine or a rubber press.
그리고 높은 수축율을 갖는 방수열수축커버(52)는 접속재의 최외부에 삽착되어 수밀성을 보다 향상기키기 위하여 내부에 수밀코팅제(54)가 융착된 구조로 되어 있으며, 또한 고무몰드애관(56)에 삽착한 후 수밀성이 더욱 확보되도록 70% 이상의 수축율을 갖는 것을 사용함이 바람직하다.In addition, the waterproof heat shrink cover 52 having a high shrinkage rate is inserted into the outermost part of the connecting member and has a structure in which a watertight coating agent 54 is fused in order to further improve watertightness, and is also inserted into the rubber mold tube 56. It is preferable to use the one having a shrinkage ratio of 70% or more so that the watertightness is further secured after the adhesion.
이상에서와 같이 본 고안은 절연체의 외경과 스트레트콘 및 절연환의 내경이 잘 맞지 않더라도, 이들 결합면의 내부 사이의 공간에 실리콘 윤활방수유가 연속적으로 채워지며, 실리콘 윤활방수유가 누유될 염려가 없으므로 전기적 절연특성이 우수하다.As described above, even if the outer diameter of the insulator and the inner diameter of the strut cone and the insulating ring do not match well, the silicone lubricating waterproof oil is continuously filled in the spaces between the insides of these coupling surfaces, and there is no fear of leakage of the silicone lubricating waterproof oil. Excellent electrical insulation characteristics.
또한 접속재의 구성이 일체형을 이루므로 외부의 수분이나 이물질이 실리콘 윤활방수유에 침투될 염려가 없으며, 단순한 작업공정과 사전 계획공정대로 작업의 이상 유무를 확인할 수 있어 간단하고 신뢰성있는 케이블접속재를 형성할 수 있다.In addition, since the structure of the connection material is integrated, there is no risk of external moisture or foreign matter penetrating into the silicone lubrication waterproofing oil. A simple and reliable cable connection material can be formed by checking the abnormality of the work according to the simple work process and the pre-planned process. Can be.
따라서 본 고안은 외부의 자연환경에 의한 수분 또는 이물질의 침투나 절연파괴로부터 보호되는 것은 물론, 신뢰성 있는 수밀구조와 접속작업공정이 단순화 된 매우 유용한 고안이다.Therefore, the present invention is not only protected from the penetration of water or foreign substances or insulation breakdown by the external natural environment, but also a very useful design that simplifies a reliable watertight structure and a connection work process.
