본 고안은 케이블의 접속부 또는 분기부(分岐部)를 분할형 케이스로, 기계적으로 체결되게 하는 기구에 있어서 케이블외피와 케이스 및 케이스상호간에 실링부재를 개재 기밀(氣密)을 유지케하는 메카니컬 죠인트에 관한 것이다. 이하, 본 고안에 대하여 종래예와 도면에 따라 설명한다.The present invention provides a mechanical joint for maintaining a hermetic seal between a cable sheath and a case and a case, in a mechanism for mechanically fastening a connection part or a branch part of a cable to a split case. It is about. EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated according to a prior art example and drawing.
제1도는 종래의 매카니컬 죠인트의 1예의 단면도이며, 제2도는 제1도의 측면도이다. (1)은 케이블, (2), (3)은 실링워셔, (4)는 실링테이프, (5)는 케이블 심선(芯線)의 접속부, (6)은 실링코-드, (7)은 반할의 죠인트케이스(8)은 반할의 죠인트케에스 체결용 보울트구멍, (9)는 보울트 및 넛트이다. 이것을 조립하는데는, 미리, 실링워셔(2), (3)을 케이블(1)에 통과시켜주고, 다음에 케이블 외피를 제거하여 심선의 접속을 행한다. 제1도에 도시되어 있지않는 우측은 도시되어 있는 좌측과 대칭이다. 심선의 접속이 완료되어 심선의 접속부(5)가 완성되면 다음 실링워셔2), (3)의 위치를 정하여 사이에 점착성(粘着性) 고무로된 실링테이프(4)를 빈틈없이 감는다.1 is a cross-sectional view of an example of a conventional mechanical joint, and FIG. 2 is a side view of FIG. (1) is the cable, (2) and (3) the sealing washer, (4) the sealing tape, (5) the cable core wire connection, (6) the sealing cord, and (7) The joint case (8) of the half is the bolt hole for fastening the joint case of the half, (9) is the bolt and nut. In order to assemble this, the sealing washers 2 and 3 are passed through the cable 1 in advance, and then the cable sheath is removed to connect the core wires. The right side, not shown in FIG. 1, is symmetrical to the left side shown. When the connection of the core wire is completed and the connection part 5 of the core wire is completed, the next sealing washers 2 and 3 are positioned, and the sealing tape 4 made of adhesive rubber is wound tightly therebetween.
다시 실링테이프와 동재질(同材質)의 실링 코-드를 죠인트 케이스(7)에 붙여진 홈에 짝지워서 붙인다. 그후 반할케이스를 제2도와 같이 맞춰서 보올트(9)를 반할 죠인트 케이스(7)에 붙혀진 구멍(8)에 통과시켜 조인다.Again, the sealing tape and the sealing material of the same material are mated to the grooves attached to the joint case (7). The half case is then tightened by passing the bolt 9 through the hole 8 attached to the joint case 7 to be cut in line with FIG.
이렇게하여 실링테이프(4) 및 실링코-드(6)은 반할죠인트케이스(7)과 상호간 및 케이블(1)과 죠인트 케이스(7)의 사이에 압착된다. 이로인하여 반할죠인트 케이스(7)의 내측은 완전히 케이스 외부와 차단되며, 예를들어 가스보수(保守)를 행할 케이블인 경우라면 접속부의 기밀(氣密)은 보존된다.In this way, the sealing tape 4 and the sealing cord 6 are crimped together with the joint case 7 and between the cable 1 and the joint case 7. As a result, the inside of the joint case 7 is completely cut off from the outside of the case. For example, in the case of a cable for gas repair, the airtightness of the connecting portion is preserved.
이와 같은 메타니컬 죠인트의 장점은 실링재(材)로 사용될 실링테이프(4) 및 실링코-드(6)이 점착성 고무이므로, 반할 죠인트 케이스(7)의 미세한 요부(凹部)나 케이블(1)의 표면상처에도 유동되어 부식(腐蝕)에 완전한 기밀을 실현할 수 있는 것이나, 반면 케이블의 클리프에 의한 실링재의 압력강하나, 부착시점보다 저온이 됐을 경우의 실링재의 수축에 의한 압력강하에 대해서는 감소되며, 점착성에 의하여 어느정도 카-바 될 수 있으며, 때로는 밀착된 공기가 새는일도 있었다.The advantage of such a mechanical joint is that the sealing tape 4 and the sealing cord 6 to be used as the sealing material are adhesive rubbers, so that the fine recesses of the joint case 7 or the cable 1 It also flows on the surface and realizes full airtightness against corrosion, while the pressure drop of the sealing material due to the creep of the cable is reduced, but the pressure drop due to shrinkage of the sealing material when the temperature is lower than the point of attachment is reduced. It can be car-bard to some degree, and sometimes close air leaks.
본 고안은 이와 같은 실링재의 장점을 살리고 또한 상술한 것과 같이 압력저하를 보상하여 실링재의 결점을 해소하고, 또 완전한 기밀성을 가진 메카니컬 죠인트를 실현하는데 있다.The present invention takes advantage of such a sealing material and also compensates for the pressure drop as described above to solve the defect of the sealing material, and to realize a mechanical joint with complete airtightness.
본 고안의 실시예를 제3도에 표시한다. (3)의 실링워셔는 반할 죠인트 케이스(7)에 그림과 같이 맞물려 고정되어 있고, 새로운 실링워셔(2')는 외경이 죠인트 케이스(7)의 내경과 동일하게만 들어져 있으며, 케이블(1)의 긴 방향으로 이동 가능하게 되어있다. 이를 조립하는데는 미리 가압볼트(12), 나사플렌지(flange)(11), 스프링(10) 및 실링워셔(2')(3)을 케이블(1)에 미리 넣어두고, 제1도의 종래법과 같이 심선의 접속, 조립을 행한다.An embodiment of the present invention is shown in FIG. The sealing washer of (3) is engaged and fixed to the opposite joint case (7) as shown in the figure, and the new sealing washer (2 ') has an outer diameter equal to the inner diameter of the joint case (7). It is possible to move in the long direction. In order to assemble this, the pressing bolt 12, the flange (flange) 11, the spring 10 and the sealing washer (2 ') (3) in advance in the cable 1, as in the conventional method of FIG. Core wires are connected and assembled.
조립완료후, 나사플렌지(11)을 나사로 반할죠인트케이스의 측면에 부착, 다시 스프링(10)을 실링워셔(2')에 눌러대고, 가압보울트(12)를 조인다. 이와 같이하면, 실링테이프(4) 및 실링코-드(6)에 스프링(10)에 의한 압력이 항상 가해지고, 케이블(1)의 외피 클리-프나 열팽창 열수축에 의한 압력변동을 보상할 수 있으며, 따라서 실링재의 압력저하에 의한 기밀누락을 방지할 수 있다. 실시예에서는 케이블의 긴방향으로 가압하는 방법을 기술하였으나, 반할죠인트 케이스(7)에 구멍을 열어, 케이블에 수직되게 가압하여도 되며, 가압기구는 메카니컬 죠인트의 설계상 편리한 것으로 좋다.After the assembly is completed, the screw flange 11 is attached to the side of the joint case to be screwed, and the spring 10 is pressed against the sealing washer 2 ', and the pressure bolt 12 is tightened. In this way, the pressure by the spring 10 is always applied to the sealing tape 4 and the sealing cord 6, and it is possible to compensate for the pressure fluctuations caused by the sheath creep of the cable 1 or thermal expansion thermal contraction. Therefore, the leakage of airtightness due to the pressure drop of the sealing material can be prevented. In the embodiment, the method of pressurizing in the longitudinal direction of the cable has been described. However, the hole may be opened in the joint case 7 and pressed vertically to the cable, and the pressurizing mechanism may be convenient for the design of the mechanical joint.
