본 발명은 통신케이블과 같은 각종 케이블의 접속부위에 물과 같은 이물질들이 침투하는 것을 방지하거나, 주위 환경으로부터의 보호를 위해 그 접속부위를 감싸아 주는데 적용되는 케이블 접속용 열수축성 슬리이브에 관한 것으로, 특히 열수축성 시트재 사이에 수축 방향에 대하여 직각 방향으로 강화 섬유가 보강된 직조물을 열수축성 시트재의 양면사이에 부착형성 함으로써, 높은 내압에 견디고 손상에 의한 파열 부위가 확산되지 않게 함은 물론 수축 현상이 균일하게 이루어지도록 한 케이블 접속용 열수축성 슬리이브에 관한 것이다.The present invention relates to a heat shrinkable sleeve for a cable connection that is applied to prevent foreign matter such as water from penetrating the connection parts of various cables such as communication cables or to surround the connection parts for protection from the surrounding environment. In particular, by adhering a woven fabric reinforced with reinforcing fibers in a direction perpendicular to the shrinkage direction between the heat shrinkable sheet members between the two sides of the heat shrinkable sheet member, it can withstand high internal pressure and prevent spreading of the rupture site due to damage as well as shrinkage. The present invention relates to a heat shrinkable sleeve for cable connection in which the phenomenon is uniformly achieved.

일반적으로 케이블 접속용 열수축성 슬리이브는 통신 케이블과 같은 각종 케이블의 접속부위에 물과 같은 이물질의 침투를 방지함은 물론 주위환경으로부터의 보호를 위한 목적으로 접속부위에 감싸는 것으로서, 그 용도의 특성상 높은 내압에 견디고 손상에 의한 파열 부위가 확산되지 않으며, 수축현상이 균일하고 또한 수축 방향에 대하여 직각방향으로도 칫수의 안정성이 우수한 제품이어야만 양질의 케이블 접속용 열수축성 슬리이브라 할 수 있는 것이다.In general, the heat shrinkable sleeve for cable connection is to prevent the ingress of foreign substances such as water into the connection parts of various cables such as communication cables and to surround the connection parts for the purpose of protection from the surrounding environment. It is a product that can withstand high heat pressure and does not spread the rupture site due to damage, and has a uniform shrinkage and excellent dimension stability in the direction perpendicular to the shrinkage direction, so that a good heat shrinkable sleeve for cable connection can be obtained.

이와 같은 열수축성 슬리이브를 구성함에 있어서, 종래에는 제6도와 같이 열수축성 섬유(61)와 강화섬유(62)를 각각 교차시켜 그물 형상의 직물로 형성한 후 이의 양면에 중합체 기저재료(63)를 적충(Laminating)시켜 구성하였는바, 케이블 접속부위에 적용되어 우수한 후프 스트레스(Hoop Stress) 및 파열에 대한 저항성이 크다는 장점은 있으나 열수축성 섬유를 얻기 위해서는 고가의 조사선 가교설비를 이용하여야만 하는 어려움을 내포하고 있다.In constructing such a heat shrinkable sleeve, conventionally, as shown in FIG. 6, the heat shrinkable fibers 61 and the reinforcing fibers 62 are intersected to form a mesh-like fabric, and then the polymer base material 63 is formed on both sides thereof. It is constructed by laminating the bar, which is applied to the cable connection part, which has the advantage of having excellent hoop stress and resistance to rupture. It is implicated.

따라서, 본 발명은 상기와 같이 고분자 중합체 섬유재와 강화섬유를 직조하여 보강용으로 사용하되 수축특성을 이용함에 있어 열수축성 시트를 사용함에 의하여 통상적인 가교방법을 행하므로써 생산성을 향상시키고 설비비 및 가공비를 절감시켜 생산원가의 절감을 극대화 함은 물론 더 나아가서는 보강재에 의하여 높은 내압에 견디고 손상에 의한 파열부위가 확산되지 않으며, 수축현상이 균일하도록 한 케이블 접속용 열수축성 슬리이브를 제공하려는데 그 목적이 있는 것이다.Accordingly, the present invention improves productivity by performing a conventional crosslinking method by using a heat-shrinkable sheet in the use of a shrinkage property by using a polymer polymer fiber material and a reinforcing fiber as described above, but using a shrinkage property to increase productivity and equipment costs and processing costs. In addition to maximizing the reduction of production cost by further reducing the cost, and furthermore, it is to provide a heat shrinkable sleeve for cable connection that withstands high internal pressure by the reinforcement material and does not spread the damage by the damage and makes the shrinkage uniform. Is there.

이하, 상기의 목적을 구체적으로 실현할 수 있는 본 발명을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings of the present invention that can specifically realize the above object will be described in detail.

제1도는 본 발명에 의한 열수축성 슬리이브의 구성물들을 나타낸 것으로 일정방향으로 열수축성을 갖는 열수축성 시트재(12) 사이로 수축방향에 대하여 직각방향으로는 강화섬유(14), 수축방향으로는 고분자 중합체 섬유재(13)을 교차시킨 직조물을 열수축성 시트재(12)의 양면사이에 부착하고 그 양면에 중합체 기저재료(11)를 부착시킨 적층구조로 구성되는데, 상기 고분자 중합체 섬유재(13)는 열수축성 시트재(12)의 수축을 방해하지 않도록 가교되지 않은 것이다.Figure 1 shows the components of the heat shrinkable sleeve according to the present invention between the heat-shrinkable sheet member 12 having heat shrinkability in a predetermined direction, reinforcing fibers 14 in the direction perpendicular to the shrinkage direction, polymer in the shrinkage direction It consists of a laminated structure in which a woven material intersecting the polymer fiber material 13 is attached between both sides of the heat-shrinkable sheet material 12 and a polymer base material 11 is attached to both sides thereof, wherein the polymer polymer fiber material 13 Is not crosslinked so as not to interfere with shrinkage of the heat shrinkable sheet material 12.

제2도는 제1도의 구성물로 열수축성 슬리이브를 제조시 열융착때 고분자 중합체 섬유재(13)가 녹아서 섬유재로서의 특성 및 형상이 없어진 상태의 완제품의 상태를 나타낸다.FIG. 2 shows the state of the finished product in a state in which the polymer polymer fiber 13 is melted at the time of heat fusion when the heat shrinkable sleeve is manufactured with the constituent of FIG.

제3도는 열수축성 시트재(12)를 단일재로 사용하고 그 일측에 강화섬유(14)와 고분자 중합체 섬유재(13)로 구성된 직조물을 배치하고 양면에 중합체 기저재료(11)를 부착 구성한 것이다.3 shows that the heat shrinkable sheet member 12 is used as a single member, and a woven material composed of the reinforcing fibers 14 and the polymer polymer fibers 13 is disposed on one side thereof, and the polymer base material 11 is attached to both sides. .

제4도는 열수축성 시트재(12)를 단일재로 사용하고 그 양측에 강화섬유(14)와 고분자 중합체 섬유재(13)로 구성된 직조물을 형성하여 양면에 중합체 기저재료(11)를 부착 구성한 것이다.4 is formed by attaching the polymer base material 11 on both sides by using a heat-shrinkable sheet member 12 as a single member and forming a woven fabric composed of reinforcing fibers 14 and a polymer polymer fiber member 13 on both sides thereof. .

이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

본 발명에 의한 열수축성 슬리이브의 열수축성은 열수축성 시트재(12)로부터 나오는데, 열수축성 시트재(12)가 수축할 때에 제5도와 같이 수축됨으로써, 수축방향에 대하여 직각 방향으로의 칫수 안정성이 뛰어난 것이다.The heat shrinkability of the heat shrinkable sleeve according to the present invention comes from the heat shrinkable sheet material 12, and when the heat shrinkable sheet material 12 shrinks as shown in FIG. 5, the dimensional stability in the direction perpendicular to the shrinkage direction is improved. It is outstanding.

이러한 열수축성 시트재(12)는 중합체 재료를 서로 교차결합(Crosslinking)하여 형성한 것으로, 이 열수축성 시트재(12)를 이용하여 제조된 열수축성 슬리이브에 열을 가하면 고분자 중합체 섬유재(13) 및 중합체 기저재료(11)가 용융되면서 열수축성 시트재(12)가 수축하게 됨에 따라 강화섬유(14)가 조밀하게 되고 직조물의 고분자 중합체 섬유재(13)는 용융되면서 섬유로서의 기능을 상실하고 강화섬유(14)를 열수축성 시트재(12) 사이에 고정시키는 역할을 하게 된다.The heat shrinkable sheet material 12 is formed by crosslinking polymer materials with each other. When heat is applied to a heat shrinkable sleeve manufactured using the heat shrinkable sheet material 12, the polymer polymer fiber material 13 ) And the heat shrinkable sheet material 12 shrinks as the polymer base material 11 melts, and the reinforcing fiber 14 becomes dense, and the polymer polymer fiber material 13 of the woven material loses its function as a fiber while melting. It serves to fix the reinforcing fiber 14 between the heat shrinkable sheet material (12).

따라서 케이블의 접속부등에 부착된 열수축성 슬리이브는 접속부를 완전히 밀폐시킴과 동시에 내충격성을 갖게 되며 손산등에 의한 파열현상에 대한 저항성이 더욱 증가됨으로써, 접속부를 외부로부터 보호하게 되는 것이다.Therefore, the heat shrinkable sleeve attached to the connection portion of the cable is completely sealed and at the same time impact resistance, and further increases the resistance to rupture caused by damage, etc., thereby protecting the connection from the outside.

또한 상기와 같은 효과를 더욱 증대시키기 위해서 열수축성 시트재(12)와 강화섬유(14)가 포함된 직조물은 필요에 따라 여러층으로 적층시켜 사용하거나 열활성 접착제 및 밀봉재, 또는 시온도료를 도포하면 그 효과가 더욱 증대되며 강화섬유(14)의 재질을 유리섬유등과 같은 비연장성 섬유로 형성하면 더욱 좋다.In addition, in order to further increase the above effects, the woven fabric including the heat shrinkable sheet material 12 and the reinforcing fiber 14 may be laminated in multiple layers as necessary, or may be coated with a thermally active adhesive, a sealing material, or a test reagent. The effect is further increased, and it is better to form the material of the reinforcing fiber 14 with non-extending fibers such as glass fibers.

이상에서와 같이 본 발명은 케이블을 접속함에 있어서, 접속부를 완전히 밀폐시킴과 동시에 내충격성을 갖게 하며 손상등에 의한 파열현상에 대하여 확산 저항성이 더욱 증가되어 케이블의 접속부를 외부로부터 완전하게 보호하여 줄 수 있는 것이다.As described above, in the present invention, when connecting a cable, the connection part is completely sealed and at the same time, the impact resistance is increased, and the diffusion resistance is further increased against the rupture phenomenon caused by damage or the like, so that the connection part of the cable can be completely protected from the outside. It is.
