As it contracts, it is in close contact with the cover 12 of the electric wire 10.

이때 반원형으로 분할된 반원슬리브(70)(71)로 플렉시블외측밴드(50)를 덮은 다음 반원슬리브(70)(71)에 형성된 플랜지(70p)(71p)를 볼트(100)와 너트(102)로 체결하게 되면, 반원슬리브(70)(71)가 원형으로 결합되며, 플렉시블외측밴드(50)의 외측면에 형성되어 있는 사다리꼴리브(54)가 반원슬리브(70)(71)의 내주면에 형성되어 있는 환형홈(72)(73)에 끼워져 결합된다.At this time, the flexible outer band 50 is covered with the semicircular sleeves 70 and 71 divided into semicircular shapes, and then the flanges 100p and 71p formed in the semicircular sleeves 70 and 71 are bolted to the bolt 100 and the nut 102. When fastened to the semicircle sleeves 70 and 71 are circularly coupled, the trapezoidal ribs 54 formed on the outer surface of the flexible outer band 50 is formed on the inner circumferential surface of the semicircle sleeves 70 and 71. It is fitted into the annular groove (72) (73) that is coupled.

그리고, 반원슬리브(70)(71)의 일측에 형성된 암나사부(77a)(77b)를 슬리브 커버(60)에 형성된 수나사부(63)에 결합하게 되면, 반원슬리브(70)(71)의 설치작업이 완료된다.고무관(30)의 외측면에 밀착되어 있는 링스프링(80)(82)은 반원슬리브(70)(71)에 형성된 스프링수용부(74)(76)에 위치되어 간섭이 발생하지 않게 된다.Then, when the female threaded portions 77a and 77b formed on one side of the semicircle sleeves 70 and 71 are coupled to the male threaded portions 63 formed on the sleeve cover 60, the installation of the semicircle sleeves 70 and 71 is performed. The work is completed. The ring springs 80 and 82 which are in close contact with the outer surface of the rubber tube 30 are located in the spring receiving portions 74 and 76 formed in the semicircle sleeves 70 and 71 so that interference occurs. You will not.

위와 같은 상태에서 반원슬리브(70)(71)의 단부에 플로트링(90)을 스크류(106)로 고정하게 되면, 플로트링(90)에 형성된 탄성조(92)가 반원슬리브(70)(71)에 단부에 형성된 테이퍼홀(78)로 삽입되면서 동시에 중심으로 모여 전선(10)을 중심에 위치시키게 된다.When the float ring 90 is fixed to the ends of the semicircle sleeves 70 and 71 with the screw 106 in the above state, the elastic tub 92 formed in the float ring 90 is the semicircle sleeves 70 and 71. At the same time, it is inserted into the tapered hole 78 formed at the end, and is gathered at the same time to position the wire 10 at the center.

즉, 고무관(30)의 내경이 전선(10)의 외경보다 훨씬 큰 경우에도 링스프링(80)(82)에 의해 고무관(30)의 허리부분이 잘록하게 수축하여 전선(10)의 피복부(12)에 밀착하기 때문에 슬리브커버(60)의 내부로 수분이나 이물질이 침투되는 것을 방지할 수 있게 된다.That is, even when the inner diameter of the rubber tube 30 is much larger than the outer diameter of the electric wire 10, the waist portions of the rubber tube 30 are contracted by the ring springs 80 and 82 so that the covering portion of the electric wire 10 may be reduced. Because it is in close contact with 12) it is possible to prevent the penetration of moisture or foreign matter into the sleeve cover (60).

또, 고무관(30)의 내측에 위치된 내측분할링(40)(42)은 고무관(30)의 형태를 유지하여 주는 작용을 하게 되며, 고무관(30)의 외측에 위치된 플렉시블외측밴드(50)는 반원슬리브(70)(71)에 걸려 있는 사다리꼴리브(54)와 내측분할링(40)(42)에 삽입되어 있는 위치결정돌기(52)에 의해 고무관(30)을 잡아 축방향으로 이동하는 것을 방지하게 된다. In addition, the inner dividing ring 40, 42 located inside the rubber tube 30 serves to maintain the shape of the rubber tube 30, and the flexible outer band 50 located outside the rubber tube 30. ) Moves in the axial direction by grasping the rubber tube 30 by the trapezoidal ribs 54 hanging on the semicircle sleeves 70 and 71 and the positioning protrusions 52 inserted into the inner dividing rings 40 and 42. To prevent it.

그리고, 스크류(106)를 이용해서 플로트링(90)을 반원슬리브(70)(71)의 단부에 체결하면서 플로트링(90)에 형성되어 있는 탄성조(92)를 반원슬리브(70)(71)에 형성된 테이퍼구멍(78)으로 삽입하게 되면, 탄성조(92)가 반원슬리브(70)(71)의 중 심으로 모이면서 전선(10)을 반원슬리브(70)(71)의 중심으로 위치결정시키게 된다.The elastic tub 92 formed in the float ring 90 is semicircle sleeves 70 and 71 while the float ring 90 is fastened to the ends of the semicircle sleeves 70 and 71 using the screw 106. When inserted into the tapered hole 78 formed in the), the elastic tub 92 gathers at the center of the semicircle sleeves 70 and 71 while the wire 10 is positioned at the center of the half circle sleeves 70 and 71. It is decided.

이때 전선(10)이 반원슬리브(70)(71)의 중심에 위치되어 있기 때문에 링스프링(80)(82)으로부터 고무관(30)을 통해 전선(10)의 피복부(12)로 전달되는 압력이 균일하게 된다.At this time, since the wire 10 is located at the center of the semi-circle sleeves 70 and 71, the pressure transmitted from the ring springs 80 and 82 to the cover 12 of the wire 10 through the rubber tube 30. This becomes uniform.

이상에서 설명한 바와 같은 본 발명은 고무관과 링스프링을 이용 슬리브커버와 전선 간의 밀폐력을 향상시킬 수 있는 효과가 있으며, 링스프링의 탄성력에 의해 고무관을 전선의 피복부를 향해 가압하는 탄성력이 지속되기 때문에 온도변화에 따른 전선의 수축과 팽창에도 밀폐력을 장시간 신뢰성 있게 유지할 수 있는 효과가 있고, 전선과 고무관 간의 유격을 크게 둘 수 있으므로, 전선의 굵기 변화에 유연하게 대응할 수 있는 효과가 있으며, 플로트링에 의해 전선을 반원슬리브 중심에 위치시키도록 구성되어 있기 때문에 링스프링으로부터 고무관을 통해 전선의 피복부로 전달되는 압력이 균일하게 되는 효과도 있다.As described above, the present invention has the effect of improving the sealing force between the sleeve cover and the wire by using the rubber tube and the ring spring, and the elastic force of pressing the rubber tube toward the covering of the wire by the elastic force of the ring spring is maintained. The sealing force can be reliably maintained for a long time even in the contraction and expansion of the wire due to the change, and the clearance between the wire and the rubber tube can be large, so that it can flexibly respond to the change in the thickness of the wire. Since the electric wire is configured to be located at the center of the semicircle sleeve, the pressure transmitted from the ring spring through the rubber tube to the sheath of the electric wire is also uniform.
