As well as the danger of fire, toxic and fire hazards, it has threatened the health and life of workers, and therefore, the removal of harmful gases in the cabinet panel has been an important task.

종래기술로서, 일본공개특허공보 특개2007-336686호에 하부틀에 하부 기밀재는 상부틀에 고정되고 하부 기밀재는 하부틀에 고정되어 상부틀과 상부기밀재를 일정한 방향으로 유동시켜 압착 또는 유동시키는 캐비넷 판넬 구성이 공지되어 있으나, 이는 배선구를 막아서 유해가스가 유입되는 것을 차단하는 것이다.As a prior art, in Japanese Patent Laid-Open No. 2007-336686, the lower hermetic material is fixed to the lower frame and the lower hermetic material is fixed to the lower frame, thereby allowing the upper frame and the upper hermetic material to flow in a certain direction to compress or flow the cabinet. Although the panel configuration is known, this is to block harmful gas from entering the wiring hole.

그러나 작업자에 의해 자주 캐비넷 판넬을 열고 닫으면서 내부로 유입되는 부식가스 등과, 차단구로 차단하더라고 차단구 등의 미세한 틈새로 유입되는 부식가스는 그대로 판넬 내에 정체되어 내부 부속품이 부식시키는 것이다.However, by frequently opening and closing the cabinet panel by the operator, the corrosion gas flowing into the inside and the blocking gas entering the minute gap such as the blocking hole are blocked in the panel and the internal components are corroded.

본 발명은 캐비넷 판넬 내로 유해가스가 유입되는 것을 차단하는 동시에 유해가스를 흡착제거할 수 있는 흡착 차단구로서, 활성탄스펀지A(153)가 장착된 프레임A(151)와, 스폰지부재B(156)가 장착된 프레임B(152)로 형성된 배선유입구의 유해가스 차단 흡착구에 관한 것이다.The present invention is an adsorption blocking port capable of adsorbing and removing harmful gas while blocking harmful gas from entering the cabinet panel, the frame A (151) equipped with the activated carbon sponge A (153), and the sponge member B (156).

표면은 배선(161)이 지나는 물결모양의 요철이 형성된 활성탄스펀지A(153)와;The surface is an activated carbon sponge A (153) having a wavy irregularity through which the wiring (161) passes;

캐비넷 판넬에 고정된 가이드(165)를 따라 움직이면서 프레임A(151)와 가까워지고 멀어질 수 있도록 형성된 프레임B(152)와;A frame B 152 formed to move closer to and away from the frame A 151 while moving along the guide 165 fixed to the cabinet panel;

표면은 배선(161)이 지나는 물결모양의 요철이 형성되며 가이드(181)를 따라 유동하면서 활성탄스펀지A(153)에 압착될 수 있도록 형성된 스폰지부재B(156)와;The surface is formed with a sponge member B 156 that is formed to be compressed into the activated carbon sponge A 153 while flowing along the guide 181 and having a wavy irregularity through which the wiring 161 passes;

프레임A(151)와 프레임B(152)를 조임하여 활성탄스펀지A(153)와 활성탄소필터B(154)의 요철부분이 압착되도록 조임하는 복수개의 조임볼트(171,172)로; 이루어진 것을 특징으로 하는 배선유입구의 유해가스 차단 흡착구에 관한 것이다.A plurality of tightening bolts 171 and 172 for tightening the uneven portions of the activated carbon sponge A 153 and the activated carbon filter B 154 by tightening the frame A 151 and the frame B 152; It relates to a harmful gas blocking adsorption port of the wiring inlet, characterized in that made.

종래 배선유입구에 유해가스 차단을 위해 상, 하 압착부재로 배선을 압착하여 배선유입구를 막아 유해가스를 차단하는 효과는 있으 작업자에 의해 수시로 판넬을 열고 닫으면서 유입되거나 배선유입구의 미세한 틈새로 유입되는 유해가스는 그대로 판넬 내에 축적되기 때문에 부식문제의 해결책이 되지 못하는 것이었다.In order to block harmful gas at the conventional wiring inlet, it is effective to block the harmful gas by blocking the wiring inlet by pressing the wire with the upper and lower crimping members.It is often introduced by opening and closing the panel by the operator or flowing into the fine gap of the wiring inlet.

도 1은 본 발명의 일 실시예 단면로서, 배선유입구를 덮어서 설치되며, 프레임A(151)는 판넬에 고정되고 프레임B(152)는 조임볼트(171,172)를 풀거나 조여 가이드(181)를 따라 유동되도록 형성된 것이다.1 is a cross-section of one embodiment of the present invention, installed by covering the wiring inlet, the frame A (151) is fixed to the panel and the frame B (152) is loosened or tightened the tightening bolts (171,172) along the guide (181) It is formed to flow.

조임볼트(171,172)를 조이면 프레임B(152)는 프레임A(151)에 접근하고 풀면 분리되도록 형성된 것으로, 조임볼트를 조이면 프레임B(152)에 장착된 활성탄스펀지B(154)가 프레임A(151)에 장착된 활성탄스펀지A(153)에 압착하게 된다.When the tightening bolts 171 and 172 are tightened, the frame B 152 approaches the frame A 151 and is formed to be detached. When the tightening bolts are tightened, the activated carbon sponge B 154 mounted on the frame B 152 is the frame A (151). ) Is pressed on the activated carbon sponge A (153) mounted on.

압착하는 두 활성탄스펀지의 표면에는 배선이 위치하기 쉽도록 물결모양의 요철(157,158)가 형성된 것이다. On the surfaces of the two activated carbon sponges to be compressed, wavy irregularities 157 and 158 are formed so that the wiring is easily located.

프레임B(152)가 판넬에 밀착상태에서 가이드(181)를 따라 조입되어 활성탄스펀지B(154)가 활성탄스펀지A(153)에 압착되면 배선유입구는 막히게 되고, 배선은 두 활성탄스펀지 사이로 관통 유입된 상태가 되며, 배선유입구로 유입되는 부식가스 등 유해가스의 판넬 유입은 차단된다. When the frame B 152 is pressed along the guide 181 in a state of being in close contact with the panel and the activated carbon sponge B 154 is pressed into the activated carbon sponge A 153, the wiring inlet is blocked and the wiring flows through the two activated carbon sponges. It enters the state, and the panel inflow of harmful gases such as corrosion gas flowing into the wiring inlet is blocked.

도 2는 본 발명의 가스차단구의 일실시예를 도시한 것으로, 프레임A(151)와 프레임B(152)는 같은 모양과 사이즈의 사각통 형상이고 그 내부에 각기 같은 모양과 사이즈의 활성탄스펀지가 삽입 장착된 것이다.Figure 2 shows an embodiment of the gas shutoff of the present invention, the frame A (151) and the frame B (152) is the same shape and size of a rectangular cylinder shape and the same shape and size of the activated carbon sponge respectively It is equipped with an insert.

프레임A(151)와 프레임B(152)는 유해가스 유통을 형성하기 위하여 다수개의 구멍이 될 수 있고, 활성탄스펀지는 수시로 교체할 수 있다.Frame A (151) and frame B (152) may be a plurality of holes to form a harmful gas distribution, the activated carbon sponge can be replaced at any time.

프레임A(151)은 캐비넷 판넬 상에 고정되고, 프레임B(152)는 가이드(181)에 의해 판넬에 밀착되어 유동되며, 조임볼트(171,172)조임되어 두 활성탄스펀지가 압착되면 배선유입구는 차단되어 캐비넷 판넬로 들어오는 공기는 차단된다.Frame A (151) is fixed on the cabinet panel, frame B (152) is flowed in close contact with the panel by a guide (181), and tightening bolts (171, 172) are tightened, so that when the two activated carbon sponges are pressed, the wire inlet is blocked. Air entering the cabinet panel is blocked.
