배터리의 벤트 캡{Vent cap of Battery}Vent cap of battery

본 고안은 축전식 배터리에서 전해액의 누출을 방지하는 벤트캡에 관한 것으로, 배터리 내부의 각 셀간 전해액편차 발생을 방지하는 것이다.The present invention relates to a vent cap that prevents leakage of electrolyte in a storage battery, and prevents electrolyte deviation between cells in the battery.

도 1 및 도 2 에 도시된 바와 같이 배터리(1)는 내부에 전해액이 담겨진 셀(Cell)이 형성되어 있고 상기 셀 상부에는 전해액 보충을 위한 홀이 형성되어 있으며 상기 홀은 벤트캡(2)에 의해 막혀지게 된다.As shown in FIGS. 1 and 2, the battery 1 has a cell in which an electrolyte is contained, and a hole for replenishing an electrolyte is formed in the upper part of the battery, and the hole is formed in the vent cap 2. To be blocked.

상기 벤트캡(2)은 하부에 포트챔버(7)가 형성되고 상부에 진동챔버(9)가 형성되며 상기 포트챔버(7)와 진동챔버(9)사이에 프레임어레스터(8)가 형성되고, 외측으로는 결합용나사(4)가 형성되며 상기 나사(4)상측으로 외부차단판(5)이 형성된다.The vent cap 2 has a port chamber 7 formed at a lower portion thereof, a vibration chamber 9 formed at an upper portion thereof, and a frame arrester 8 formed between the port chamber 7 and the vibration chamber 9 formed therein. On the outside, a coupling screw 4 is formed and an outer shielding plate 5 is formed above the screw 4.

포트챔버(7)에는 전해액의 튀김을 방지하는 차단캡(10)이 끼워지고 배터리(1)홀과의 밀착을 위한 시이트(3)가 끼워진다.The port chamber 7 is fitted with a blocking cap 10 to prevent splashing of the electrolyte and a sheet 3 for close contact with the holes of the battery 1.

그리고 상측으로는 내외부가 관통되는 하나의 벤트홀(6)을 형성시킨다.In addition, the vent hole 6 penetrates the inside and the outside thereof.

상기된 벤트캡(2)을 배터리(1)에 사용한 상태에서 장시간 진동이나 충격이 있게되면 각 셀간의 전해액 차이가 발생하는 한편 가스의 충진에 의해 폭발할 우려가 있는 것이었다.In the state where the vent cap 2 is used for the battery 1, when there is a vibration or shock for a long time, an electrolyte difference between the cells may occur and an explosion may occur due to filling of the gas.

여기서 벤트캡(2)의 벤트홀(6)은 배터리(1)상부의 관통구조에 의해 서로 통하게 한 후 외기와도 서로 통하게 결합된다.Here, the vent hole 6 of the vent cap 2 is connected to each other by the outside air after passing through each other by the through structure of the upper part of the battery (1).

배터리(1)가 진동이나 충격을 받게 되면 각 셀에 균등히 차있던 전해액이 흔들리면서 벤트캡(2)쪽으로 튀겨지게 되고 벤트캡(2)을 향하여 퇴겨진 전해액과 진동이나 충격에 의해 발생된 가스는 벤트홀(6)을 통하여 외부로 배출된다.When the battery (1) is subjected to vibration or shock, the electrolyte, which is filled in each cell, is shaken and splashed toward the vent cap (2), and the electrolyte discharged toward the vent cap (2) and the gas generated by the vibration or shock are vented. It is discharged to the outside through the hole (6).

이때 벤트캡(2)의 차단캡(10)등에 의해 최대한 누출을 방지하지만 진동이나 충격에 의해 어느정도의 전해액 누출은 피할 수 없다.At this time, the leakage cap is prevented as much as possible by the blocking cap 10 of the vent cap 2, but leakage of the electrolyte to some extent cannot be avoided by vibration or shock.

벤트홀(6)로 유출된 전해액은 다시 셀로 스며들어야 하나 외부차단판(5)에 의해 셀로의 재유입이 차단되므로 특정셀에는 기준레벨 보다 높게 전해액이 차있게 되고 어느셀에는 기준레벨 이하가 되어 배터리 성능을 저하시키는 것이었다.The electrolyte leaked into the vent hole 6 must penetrate into the cell again, but the reflow of the electrolyte into the cell is blocked by the external blocking plate 5, so that the electrolyte is filled higher than the reference level in certain cells, and the cell is lower than the reference level. It was to degrade the battery performance.

또한 벤트홀(6)로 가스가 원활히 배출되어 외부로 방출되어야 하나 하나의 벤트홀(6)에 의해서는 충분한 량의 가스배출이 어려워 셀안에 가스가 충진되는 경우가 발생되고 가스압이 높은 경우 충격에 의해 배터리(1)가 폭발할 우려가 있는 것이었다.In addition, the gas should be smoothly discharged to the vent hole 6 to be discharged to the outside. However, a sufficient amount of gas is difficult to be discharged by one vent hole 6 so that gas is filled in the cell. The battery 1 could be exploded by this.

본 고안은 배터리의 셀간 내부압 편차를 없애주어 전해액 편차가 발생되는 것을 방지하고 가스의 원활한 배출로 폭발위험을 방지하도록 한 것이다.The present invention is to eliminate the deviation of the internal pressure between the cells of the battery to prevent the deviation of the electrolyte is generated to prevent the explosion risk by the smooth discharge of gas.

이러한 본 고안은 배터리의 전해액 투입홀에 나사식으로 끼워져 결합되는 벤트캡에 있어서, 상기 벤트캡 내부의 포트챔버는 공간을 줄이고 진동챔버의 공간은 넓히는 한편 벤트홀의 직경이 넓게 양쪽으로 뚫어주고 외측나사 상부의 외부차단판을 없앰으로써 이루어지는 것으로 벤트캡의 포트챔버와 진동챔버의 면적변화와 함께 벤트홀의 직경이 크게 양쪽으로 뚫어주므로써 전해액의 누출은 방지되고 가스는 쉽게 배출이 되며 벤트홀로 빠져나온 전해액은 나사를 타고 셀로 재유입되는 것이다.The present invention is a vent cap that is screwed into the electrolyte injection hole of the battery screw coupled, the port chamber inside the vent cap reduces the space, the space of the vibration chamber is widened while the diameter of the vent hole is wide open on both sides and the outer screw It is made by removing the upper external blocking plate, and the diameter of the vent hole is greatly penetrated to both sides along with the change of the area of the port chamber and the vibration chamber of the vent cap to prevent leakage of the electrolyte and the gas to be easily discharged. Is screwed back into the cell.

본 고안은 도 3 및 도 4 에 도시된 바와 같이 벤트캡(20)에 있어서, 상부에 벤트캡(20) 조립을 위한 벤트캡체결홈(21)을 형성시키는 한편 기존 벤트캡(2)에서 나사(4)상부에 형성된 외부차단판(5)을 제거하고, 벤트캡(20)내부의 포트챔버(26)면적은 축소하고 진동챔버(24)의 면적은 확대하며, 좌,우측으로 2개의 벤트홀(28)(29)을 형성시키되 상기 벤트홀(28)(29)은 기존 벤트캡(2)의 벤트홀(6) 보다 직경이 크도록 한 것이다.The present invention, as shown in Figure 3 and 4, in the vent cap 20, forming a vent cap fastening groove 21 for assembling the vent cap 20 on the top while the screw in the existing vent cap (2) (4) Remove the outer blocking plate 5 formed on the upper part, reduce the area of the port chamber 26 inside the vent cap 20, enlarge the area of the vibration chamber 24, and two vents to the left and the right. The holes 28 and 29 are formed, but the vent holes 28 and 29 are larger in diameter than the vent holes 6 of the existing vent cap 2.

이러한 본 고안의 벤트캡(20)은 도 1 에 도시된 기존 벤트캡(2)과 일견 유사하게 보일 수 있으나 여러곳에서 배터리(1)의 내부압 편차를 없애주고 가스폭발을 방지하기 위한 구조를 갖추고 있다.The vent cap 20 of the present invention may look similar to the existing vent cap 2 shown in FIG. 1, but the structure for removing the internal pressure deviation of the battery 1 and preventing a gas explosion in various places. Equipped.

먼저 벤트캡(2)내부에서 차단캡(27)이 끼워져 진동이나 충격에 의한 전해액의 튀김을 1차로 저지하는 포트챔버(26)는 그 면적을 축소시켜 최대한 전해액의 방출을 저지하도록 한다.First, the blocking cap 27 is inserted into the vent cap 2 to prevent the release of the electrolyte as much as possible by reducing the area of the port chamber 26 that primarily prevents the splash of the electrolyte due to vibration or shock.

즉 기존 벤트캡(2)의 포트챔버(7)면적은 1905mm3였으나 본 고안 벤트캡(20)의 포트챔버(26)면적은 1350mm3으로 축소시킨다.That is, the area of the port chamber 7 of the existing vent cap 2 was 1905 mm 3, but the area of the port chamber 26 of the vent cap 20 of the present invention was reduced to 1350 mm 3 .

그리고 벤트캡(20)의 진동챔버(24)는 그 면적을 315mm3에서 380mm3으로 확대시킴으로써 전해액의 방출은 방지하고 발생가스의 방출은 용이하도록 한다.And the oscillation chamber 24 of the vent cap 20 is released in the electrolyte, by expanding the area of 380mm by 315mm 3 eseo 3 is prevented and the release of generated gas is to facilitate.

진동챔버(24)가 커지면 액상체인 전해액은 방출이 저지되나 상부 면적이 확대되어 가스의 방출은 도와주게 된다.When the vibration chamber 24 is enlarged, the electrolyte solution, which is a liquid, is prevented from being discharged, but the upper area is enlarged to help release of the gas.

본 고안 벤트캡(20)에는 2개의 벤트홀(28)(29)을 형성시키는 한편 직경을 2.0mm에서 3.0mm로 확대시켜 진동이나 충격에 의해 발생된 가스의 배출이 용이하게 이루어지도록 한다.The vent cap 20 of the present invention forms two vent holes 28 and 29 while expanding the diameter from 2.0 mm to 3.0 mm to facilitate the discharge of the gas generated by vibration or shock.

또한 배터리(1)상부구조물과 결합되는 나사(23)의 상부에는 외부차단판(5)을 형성시키지 않아 벤트홀(28)(2)을 통하여 배출된 전해액이 다시 나사(23)를 타고 셀로 재유입될 수 있도록 하므로써 전해액의 셀간 높이편차를 줄여주게 된다.In addition, since the external blocking plate 5 is not formed on the upper part of the screw 23 coupled to the upper structure of the battery 1, the electrolyte discharged through the vent holes 28 and 2 is returned to the cell through the screw 23. By allowing the inflow, the height difference between the cells of the electrolyte is reduced.

벤트캡(20)의 상부에는 벤트캡체결홈(21)을 형성시켜 자동화된 공정에 의거 벤트캡(20)의 끼움이 용이하게 한다.The vent cap fastening groove 21 is formed on the upper portion of the vent cap 20 to facilitate the fitting of the vent cap 20 based on an automated process.

본 고안은 배터리의 전해액 투입홀을 막아주는 벤트캡에 있어서, 포트챔버는 축소시키고 진동챔버는 확대시키는 한편 외부차단판은 없애고 벤트홀의 직경을 크게 하여 양쪽으로 뚫어주므로써 배터리의 셀간 내부압을 제거하여 전해액 높이차이 발생을 방지하고, 가스의 방출을 쉽게 하여 폭발 위험성을 없애며, 벤트홀로 배출된 전해액이 다시 셀로 재유입될 수 있는 것이다.The present invention is a vent cap that blocks the electrolyte injection hole of the battery, the port chamber is reduced and the vibration chamber is enlarged, while the external blocking plate is eliminated, the diameter of the vent hole is increased to both sides to remove the internal pressure between the cells This prevents the difference in electrolyte height, facilitates the release of gas, eliminates the risk of explosion, and the electrolyte discharged into the vent hole can be flowed back into the cell.
