본 고안은 밀폐형 축전지의 양음극 단자 씰링 장치에 관한 것으로, 특히 제작과 조립이 극히 용이하면서도 전해액의 누설을 적극적으로 방지할 수 있도록 한 것이다.The present invention relates to a positive electrode terminal sealing device of a sealed storage battery, and particularly to manufacture and assembly is very easy to prevent the leakage of the electrolyte.

일반적으로 밀폐형 축전지는 케이싱의 양측에 양음극 단자가 돌출 구비되어 있으며, 소정의 씰링 구조에 의해 케이싱과 단자 사이로의 전해액 누설을 방지하고 있다.In general, a sealed battery includes positive electrode terminals protruding on both sides of a casing, and prevents leakage of electrolyte between the casing and the terminal by a predetermined sealing structure.

제1도는 종래 씰링 구조를 예시한 것으로, (a)에서는 케이싱(1)의 보스부(11)에 경사상의 나사홈(12)을 형성시키고, 상기 나사홈(12)에 나사산(21)으로 대응 결합하는 납(plumbum)재의 부싱(2) 중앙에는 원뿔형의 극주(3)가 삽입되는 고정구멍(22)을 형성하여 극주(3)에 의해 그 하단이 폐쇄되도록하며, 상기 고정구멍(22)을 형성하여 극주(3) 사이의 공간부에는 케이싱(1)의 상부로 돌출되도록 용융된 납으로 용접하여 단자(4)를 형성시킨 구성을 나타내었다.FIG. 1 illustrates a conventional sealing structure. In (a), an inclined screw groove 12 is formed in the boss portion 11 of the casing 1, and the screw groove 12 corresponds to the thread 21. FIG. In the center of the bushing 2 of the joining plumbing material, a fixing hole 22 into which the conical pole column 3 is inserted is formed so that the lower end thereof is closed by the pole column 3, and the fixing hole 22 is closed. In the space portion between the poles 3, the terminal 4 was formed by welding molten lead so as to protrude to the upper portion of the casing 1.

또한, 제1도 (b)에서는 케이싱(1)의 보스부(11)내에 경사상의 고정구멍(13)과 걸림턱(14)을 형성시켜서 극주(3)와의 사이를 통해 연질고무재의 패킹(5)을 압입시키고, 걸림턱(14)과 극주(3)의 사이는 0링(6)으로 폐쇄시킨 뒤 에포시레진(epoxy resin:7)을 고정구멍(13)에 충전하여 극주(3)를 고정시킨 구성을 나타내었다.In FIG. 1 (b), the inclined fixing hole 13 and the locking jaw 14 are formed in the boss 11 of the casing 1, and the packing of the soft rubber material 5 between the poles 3 is formed. ), And the locking jaw (14) and the pole (3) is closed between the ring (0) and the zero ring (6) and then filled with an epoxy resin (7) in the fixing hole (13) to fill the pole (3) The fixed configuration is shown.

이와같은 구성의 종래 씰링 구조에서는 (a)의 경우, 단자(4)의 외면에 전선 케이블(8) 끝단의 홀더(8a)를 고정하여 전기적으로 연결시키고, (b)의 경우에는 극주(3)에 매립 고정시킨 나사부(31)에 전선 케이블(8) 끝단의 홀더(8a)와 와셔(9,9')를 끼우고 너트(32)로 조임하여 전기적으로 연결시키게 됨은 주지와 같다.In the conventional sealing structure having such a configuration, in the case of (a), the holder 8a at the end of the wire cable 8 is fixed and electrically connected to the outer surface of the terminal 4, and in the case of (b), the pole column 3 It is well known that the holder 8a and the washers 9 and 9 'at the end of the electric wire cable 8 are screwed into the screw part 31 embedded in the screw 31 and tightened with the nut 32 to be electrically connected.

그런데, (a)의 경우 부싱(2)을 고정시킨 상태에서 극주(3)의 상부에 용융된 납을 용접하여 단자(4)를 돌출 형성시켜야 하므로 그 제작이 매우 번거롭고, (b)의 경우에도 패킹(5)을 압입시킨 뒤 0링(6)과 함께 에폭시레진(7)을 충전시켜 고정구멍(13)을 폐쇄시켜야 하는 제작과 조립상의 어려움으로 인해 작업성과 생산성이 저하되는 문제점이 지적된다.However, in the case of (a), the molten lead is welded to the upper portion of the pole column 3 while the bushing 2 is fixed, so that the terminal 4 is protruded to be formed, which is very cumbersome, even in the case of (b). It is pointed out that the workability and productivity are deteriorated due to the difficulty in manufacturing and assembling that the packing 5 is press-fitted and the epoxy resin 7 is filled with the 0 ring 6 to close the fixing hole 13.

또한, 조립후 사용할 때에는 케이싱(1)에 가해지는 진동, 충격 또는 외부와의 온도 차이 등에 의해 (a)의 경우 나사홈(12)과 나사산(21)사이, (b)의 경우에는 고정구멍(13)과 에폭시레진(7)의 사이로 전해액이 누출되는 문제점도 발생되며, 이점은 특히 주변 구성 부품들을 오염 훼손시킴과 동시에 부식을 유발하여 외관 불량과 수명 단축의 주요인을 제공하게 된다.In addition, in the case of use after assembling, due to vibration, shock or temperature difference between the outside of the casing 1, between the screw groove 12 and the thread 21 in the case of (a), and the fixing hole (in the case of (b)) 13) and the leakage of the electrolyte between the epoxy resin (7) also occurs, the advantage is to damage the surrounding components and at the same time cause corrosion and to provide a major cause of poor appearance and shortened life.

도면중 미설명 부호(17)은 보강 리브이다In the figure, reference numeral 17 is a reinforcing rib.

이와같은 구성의 본 고안 씰링장치(S)는 조립시에 극주(3)의 상단이 케이싱(1)의 상부로 돌출되도록 케이싱(1)을 복개시킨 상태에서 고정링(10)과 패킹(5A), 가압링(20)을 보스부(11) 내면의 고정구멍(13a)에 삽입한 후 체결부재(30)의 나사부(302)를 고정구멍(13a) 상단의 나사부(16)에 일치시킨 상태에서 도시되지 않은 공구를 공구홈(303)에 삽입하여 체결부재(30)를 회전시킴으로써 조립을 진행하게 된다.The sealing device S of the present invention having such a configuration has the fixing ring 10 and the packing 5A in a state in which the casing 1 is covered so that the upper end of the pole column 3 protrudes to the upper part of the casing 1 at the time of assembly. In a state in which the pressure ring 20 is inserted into the fixing hole 13a of the inner surface of the boss 11 and the threaded portion 302 of the fastening member 30 coincides with the threaded portion 16 of the upper end of the fixing hole 13a. Inserting a tool (not shown) into the tool groove 303 to proceed with the assembly by rotating the fastening member 30.

이때, 고정링(10)은 그 외주연의 걸림돌출부(102)가 보스부(11)의 지지돌출부(15)에 걸림지지되어 고정링(10)의 하강이 방지됨과 동시에 고정구멍(13a)의 하단을 폐쇄시키게 되며, 이러한 상태에서는 고정링(10)과 패킹(5A), 가압링(20) 및 체결부재(30)의 삽입구멍(101,51,201,301)과 극주(3) 사이에는 용이한 삽입을 위한 약간의 간격이 유지된 상태가 된다.At this time, the fixing ring 10 is supported by the engaging protrusion 102 of the outer peripheral edge of the boss protrusion 11 of the support protrusion 15 is prevented from falling of the fixing ring 10 and at the same time of the fixing hole 13a The lower end is closed, and in this state, easy insertion is provided between the fixing ring 10, the packing 5A, the pressure ring 20, and the insertion holes 101, 51, 201, 301 and the pole column 3 of the fastening member 30. Some gaps are maintained.

이러한 상태에서 체결부재(30)의 나사 결합을 진행시키게 되면, 가압링(20)에는 체결부재(30)가 하향 이동한 만큼의 압력이 가해지게 되는데, 이때 하향 이동하는 가압링(20)과 보스부(11) 하단에 걸림 지지된 고정링(10) 사이의 패킹(5A)은 상기 압력에 의해 압박되어 외측으로 팽창된다.When the screw coupling of the fastening member 30 proceeds in such a state, pressure is applied to the pressure ring 20 as much as the fastening member 30 moves downward, and the pressure ring 20 and the boss moving downwards at this time. The packing 5A between the fixing rings 10 held at the bottom of the portion 11 is pressed by the pressure and expands outward.

특히, 고정링(10)과 가압링(20)의 상하면에는 산형의 압박부(103,203)가 형성되어 있으므로 패킹(5A)은 내외측 즉, 삽입구멍(51)측과 고정구멍(13a)측으로 동시에 팽창되며, 이에따라 고정구멍(13a)과 패킹(5A), 패킹(5A)과 극주(3) 사이는 완벽한 수밀 상태가 유지되어 전해액의 누설 우려는 근본적으로 해소된다.In particular, the upper and lower surfaces of the fixing ring 10 and the pressing ring 20 are formed with the pressing portions 103 and 203, so that the packing 5A is at the same time inward and outward, i.e., the insertion hole 51 side and the fixing hole 13a side. As a result, a perfect watertight state is maintained between the fixing hole 13a and the packing 5A, the packing 5A, and the pole column 3, thereby eliminating the risk of leakage of the electrolyte solution.

또한, 상기한 수밀 상태는 축전지의 사용할 때에 외부로부터 진동, 충격이 가해져 극주(3)가 약간 유동될 경우에도 견고한 상태로 유지되며, 이러한 수밀 상태가 이완되는 경우에는 체결부재(30)를 더욱 조여줌으로써 간단히 복구된다.In addition, the above watertight state is maintained even when the pole 3 is slightly flown due to vibration and shock applied from the outside when the battery is used, and when the watertight state is relaxed, further tighten the fastening member 30. Simply recover.

이와같은 본 고안 씰링장치(S)는 제작과 조립이 극히 용이하고, 조립된 상태에서는 견고한 수밀 상태를 유지하게 되므로, 제작과 조립의 용이함에 의한 작업성과 수율향상, 전해액의 누설 방지에 의한 주변 부품의 훼손, 부식 방지의 효과를 얻을 수 있으며, 외관 불량 해소와 수명 연장에 의해 사용자의 제품 신뢰도를 향상시킬 수 있게된 유용한 고안이다.Since the sealing device S of the present invention is extremely easy to manufacture and assemble, and maintains a tight watertight state in the assembled state, the workability and yield improvement due to ease of manufacture and assembly, and peripheral parts by preventing leakage of electrolyte solution. It is a useful design that can improve the reliability of users' products by eliminating defects and preventing corrosion, and by eliminating poor appearance and extending the lifespan.
