According to the present invention, a pair of longitudinal housings (20) in which openings are joined to each other and wire holes (21) are formed in the attachment part and the housing (20) are embedded and connected. It is composed of a binding pipe 37, a female, and a water coupling cylinder 32, 31 for binding the conductive wire 13 in the wire 10 to each other, and a waterproof filler 99 such as an epoxy resin in the bonded housing 20. Is charged, the wire 10 is connected to the wire 10, as well as to enable a strong physical and electrical connection, expressing a high waterproof.

수중펌프, 수중 수류발생장치 및 전동 밸브와 같이 수중에서 작동되는 각종 유체기계는 모터 및 구동회로 등 전기장치의 안정적인 작동을 위하여 고도의 수밀성이 부여되며, 이러한 수밀성은 전기장치 자체 뿐 아니라 전원을 인가하거나 제어 신호를 전송하는 전선(10)에도 필수적으로 요구된다.Various hydromechanical devices that operate underwater, such as submersible pumps, submersible water generators and electric valves, are endowed with high watertightness for stable operation of electric devices such as motors and drive circuits. It is also essential to the wire 10 for transmitting or transmitting a control signal.

특히, 호소(湖沼)내 수류발생장치와 같이 대수심, 대용량의 유체기계의 경우 높은 수압은 물론 파랑 및 수류에 의하여 전선(10)에 작용하는 외력에 대한 충분한 대처가 가능하도록 통상의 수밀성을 능가하는 고도의 방수성 및 견고한 물리적 체결강도가 필요하다.
Particularly, in the case of large-scale, large-capacity fluid machines, such as water flow generators in lakes, the conventional watertightness is surpassed to allow sufficient coping with external forces acting on the wires 10 due to high water pressure as well as wave and water flow.

Or when the tension-side external force acting on the wire 10 it was virtually impossible to cope with this.

이에, 절연테이프를 반복하여 감싸고 전선(10) 박스 등에 연결부를 수납한 후 전선(10) 박스 내부에 이탈 방지 매듭을 형성하고 파라핀(paraffin)계 충전제를 주입하는 등의 처리를 하였으나, 이 또한 방수 성능에 한계가 있을 뿐 아니라, 연결부의 부피가 지나치게 커지고 작업 공정이 복잡하여 작업시간과 인력이 과다하게 소요되는 심각한 문제점이 있었다.
In this case, the insulation tape was repeatedly wrapped and the connection part was stored in the box of the wire 10, and then the separation prevention knot was formed inside the box of the wire 10 and a paraffin filler was injected. In addition to the performance limitations, there was a serious problem of excessively large working time and manpower due to the excessively large volume of the connection and the complicated work process.

Communication holes 22 into which fillers 99, such as epoxy, are injected, are formed.

도시된 실시예에서는 상, 하 하우징(20)의 개구부에 각각 나선이 형성되어 나사식으로 접합되고 있으며, 연통공(22)이 전선공(21)과 인접하여 형성되었으나, 충전체(99)의 주입이 가능한 위치라면 연통공(22) 천공위치는 변경될 수도 있다.In the illustrated embodiment, spirals are formed in the openings of the upper and lower housings 20, respectively, and screwed together, and communication holes 22 are formed adjacent to the wire holes 21, but If the injection position is possible, the communication hole 22 drilling position may be changed.

도시된 실시예에서는 수결합통(31)과 암결합통(32)이 직경이 동일한 원통으로 구성되며, 수결합통(31)의 일단에는 결합돌부(35)가 형성되고, 암결합통(32)의 일단부에는 결합돌부(35)와 일치하는 형상의 결합요부(36)가 형성되어 이들 결합돌부(35) 및 결합요부(36)간 결합에 의하여 암결합통(32)과 수결합통(31)이 체결되며, 수결합통(31)과 암결합통(32) 공히 종방향 즉, 하우징(20)의 축방향으로 천공된 도선공(33) 및 출입공(34)이 형성된다.In the illustrated embodiment, the male coupling cylinder 31 and the female coupling cylinder 32 are composed of a cylinder having the same diameter, and one end of the male coupling cylinder 31 has a coupling protrusion 35 formed thereon, and the female coupling cylinder 32 At one end of the coupling protrusion 35 is formed in the shape corresponding to the coupling protrusion 35 is formed by the coupling between the coupling protrusion 35 and the coupling recess 36, female coupling cylinder 32 and the water coupling cylinder ( 31 is fastened, and both the male coupling cylinder 31 and the female coupling cylinder 32 are formed with a lead hole 33 and an entrance hole 34 drilled in the longitudinal direction, that is, in the axial direction of the housing 20.

또한, 도 3의 우측단 도면에서와 같이, 결합돌부(35)의 돌출 길이 보다 결합요부(36)의 깊이를 깊게 형성하여, 수결합통(31)과 암결합통(32)의 결합시 결합돌부(35) 선단면과 결합요부(36) 내측 표면간 공동(空洞)이 형성되도록 하고, 추후 충전체(99)의 주입시 출입공(34)을 통하여 유입된 충전체(99)가 상기 공동에 충전되도록 함으로써 긴밀한 방수는 물론 견고한 물리적 연결이 가능하도록 하였다.In addition, as shown in the right end of Figure 3, the depth of the coupling recess 36 is formed deeper than the protruding length of the coupling protrusion 35, the coupling when coupling the male coupling cylinder 31 and the female coupling cylinder (32) The cavity 35 is formed between the distal end surface of the protrusion 35 and the inner surface of the coupling recess 36, and the filler 99 introduced through the entrance hole 34 when the filler 99 is injected later is the cavity. The battery pack is charged with a seal, allowing for tight waterproofing and robust physical connections.

도 4 및 도 5는 본 발명을 통한 전선(10)의 연결방식, 즉 충전체(99) 주입 전 전선(10)간 물리적, 전기적 연결과정을 도시한 것으로, 도 4에 도시된 바와 같이, 일단 전선(10)의 외피복체(11)를 충분히 제거하여 내피복체(12)를 소정 길이 이상 노출시키고, 다시 내피복체(12)를 부분 제거하여 도선(13)을 노출시킨 후 하우징(20), 수결합통(31) 또는 암결합통(32)에 순차적으로 삽입한다.4 and 5 illustrate a connection method of the wire 10 according to the present invention, that is, a physical and electrical connection process between the wires 10 before the filling body 99 is injected, as shown in FIG. After removing the outer shell 11 of the electric wire 10 sufficiently, the inner shell 12 is exposed to a predetermined length or more, and the inner shell 12 is partially removed to expose the conductor 13, and then the housing 20 ), The male coupling cylinder 31 or the female coupling cylinder 32 is sequentially inserted.

이후, 도 5에서와 같이, 수결합통(31) 또는 암결합통(32)을 통과하여 노출된 양측 도선(13) 및 내피복체(12)에 금속제 결속관(37)을 체결하고 공구을 이용하여 압착하여 양측 도선(13)을 전기적으로 연결함과 동시에 양측 내피복체(12)를 물리적으로 1차 연결하게 되며, 수결합통(31)과 암결합통(32)을 결합하면 결속관(37)이 수결합통(31) 및 암결합통(32)의 도선공(33)에 결합되면서 재차 고정된다.Thereafter, as shown in FIG. 5, the metal binding pipe 37 is fastened to both of the conductive wires 13 and the inner coating body 12 exposed through the male coupling cylinder 31 or the female coupling cylinder 32 and used with a tool. By crimping to electrically connect the two conductive wires (13) and at the same time to physically connect both inner coating body (12), the coupling tube (31) and the female coupling cylinder (32) by combining the binding pipe ( 37 is fixed again while being coupled to the lead hole 33 of the male coupling cylinder 31 and the female coupling cylinder (32).

이렇듯 수결합통(31) 및 암결합통(32)을 이용한 도선(13) 및 내피복체(12)간 연결이 완료되면 양측의 하우징(20) 개구부를 접합하고 에폭시수지 등의 충전체(99)를 연통공(22)을 통하여 주입, 충전하고 경화시킴으로써 도 6과 같은 상태의 연결장치를 구성하게 된다.As such, when the connection between the conductive wire 13 and the inner covering body 12 using the male coupling cylinder 31 and the female coupling cylinder 32 is completed, the openings of the housings 20 on both sides are joined to each other, and a filler such as an epoxy resin (99). ) Is injected, filled and cured through the communication hole 22 to form a connection device as shown in FIG. 6.

하우징(20) 내부로 주입된 충전체(99)는 도 7에서와 같이, 수결합통(31) 및 암결합통(32)에 형성된 출입공(34)을 통하여 전술한 결합돌부(35) 선단면과 결합요부(36) 내측 표면간 공동(空洞)에 충전되어 일층 견고한 물리적 연결 및 방수성을 발현하게 된다.Filling body 99 injected into the housing 20, as shown in Figure 7, through the access hole 34 formed in the male coupling cylinder 31 and the female coupling cylinder 32, the above-mentioned coupling protrusion 35 line It is filled in the cavity between the cross section and the inner surface of the coupling recess 36 to express a solid physical connection and waterproofness.

한편, 도 8 내지 도 11은 주입튜브(39)가 적용된 본 발명의 일 실시예를 도시한 것으로, 암결합통(32)의 결합요부(36) 내부 공동과 하우징(20) 외부를 연결하는 주입튜브(39)를 통하여 충전체(99)를 주입할 수 있도록 한 것이다.Meanwhile, FIGS. 8 to 11 illustrate one embodiment of the present invention to which the injection tube 39 is applied. An injection connecting the inner cavity of the female coupling cylinder 32 to the inner cavity of the female coupling cylinder 32 and the exterior of the housing 20 is performed. It is to be able to inject the filler 99 through the tube (39).

즉, 하우징(20)에 형성된 연통공(22)을 통하여 충전체(99)를 주입할 경우 충전체(99)의 점성으로 인하여 출입공(34)을 통한 공동내로의 원활한 유입이 어려울 수 있으며, 이로 인하여 충전체(99) 내부에 기포가 형성되는 등의 불량이 발생될 수 있으므로, 이를 근본적으로 방지할 수 있도록 한 것이다.That is, when the filler 99 is injected through the communication hole 22 formed in the housing 20, smooth inflow into the cavity through the entrance hole 34 may be difficult due to the viscosity of the filler 99. As a result, since defects such as bubbles are formed in the filling body 99 may be generated, it is possible to fundamentally prevent this.

주입튜브(39)는 가요성 관체(管體)로서, 도 8 및 도 9에서와 같이, 암결합통(32) 외주면에 형성되고 결합요부(36) 내측 공동과 외부를 연결하는 주입구(38)에 일단이 결합되며, 타단은 하우징(20)에 형성된 튜브공(23)을 통하여 외부로 노출되는데, 도 9의 우측 도면에서와 같이, 하우징(20)의 개구부 접합 직전에 주입튜브(39)의 말단부를 튜브공(23)을 통하여 외부로 노출시킨 후, 도 10에서와 같이 노출된 주입튜브(39)의 말단부를 통하여 충전체(99)를 주입한다.The injection tube 39 is a flexible tube, and as shown in FIGS. 8 and 9, an injection hole 38 formed on the outer circumferential surface of the female coupling cylinder 32 and connecting the inner cavity of the coupling recess 36 to the outside is connected to the injection hole 38. One end is coupled to, the other end is exposed to the outside through the tube hole 23 formed in the housing 20, as shown in the right side of Figure 9, just before the opening junction of the housing 20 of the injection tube 39 After exposing the distal end to the outside through the tube hole 23, the filler 99 is injected through the distal end of the exposed injection tube 39 as shown in FIG.

도 10에서와 같이, 주입튜브(39)를 통하여 주입된 충전체(99)는 수결합통(31)과 암결합통(32)간 결합부 내측에 형성된 공동에 우선 충전된 후 출입공(34)을 통하여 유출되어 하우징(20) 내부를 충전하게 되며, 충전이 완료되면 연통공(22)을 통하여 누출됨으로써 사용자가 충전의 완료여부를 확인할 수 있다.As shown in FIG. 10, the filler 99 injected through the injection tube 39 is first filled in the cavity formed inside the coupling portion between the male coupling cylinder 31 and the female coupling cylinder 32, and then the entrance hole 34. It flows out through) to charge the inside of the housing 20, and when the filling is completed, the leakage through the communication hole 22 allows the user to check whether the filling is completed.

충전이 완료되면 도 11에서와 같이, 주입튜브(39)를 인발하여 제거할 수도 있으며, 연통공(22) 및 튜브공(23)으로 충전체(99)가 누출되어 형성된 스크랩(scrap)을 제거함으로써 전선(10)의 방수 연결이 완료된다.
When the filling is completed, as shown in FIG. 11, the injection tube 39 may be removed and removed, and the scrap 99 formed by leakage of the filler 99 into the communication hole 22 and the tube hole 23 may be removed. This completes the waterproof connection of the wire 10.
