Description

전자장비함의 덮개 결합구조{EMI closing cover}Cover structure of electronic equipment box {EMI closing cover}

본 발명은 전자장비를 수납하는 전자장비함의 덮개에 관한 것으로, 특히 전자장비함에 수납된 전자장비를 사용할 때 신속하게 개방할 수 있고, 차폐효과도 높일 수 있는 EMI 차폐 덮개에 관한 것이다.The present invention relates to a cover of an electronic equipment box for storing electronic equipment, and more particularly, to an EMI shielding cover that can be opened quickly and can increase the shielding effect when using the electronic equipment stored in the electronic equipment box.

예민한 전자장비들은 전자파 방해로 인하여 본래 기능을 상실할 우려가 있으므로 전자파나 진동 또는 충격으로부터 보호할 수 있는 전자장비함에 수납하여 운용한다.Sensitive electronic equipments may lose their original function due to electromagnetic interference, so they are stored in electronic equipment that can be protected from electromagnetic waves, vibrations or shocks.

이렇게 수납된 전자장비를 점검하거나 정비 할 때에는 전자장비함을 개방하여야 하므로 전자장비함에는 전자장비함을 개폐할 수 있는 덮개가 설치된다.When inspecting or maintaining the electronic equipment stored in this way, the electronic equipment box should be opened. Therefore, a cover for opening and closing the electronic equipment box is installed.

전자장비를 진동이나 충격으로부터 보호하기 위해서는 전자장비함에 충격흡수장치나 충격을 효과적으로 흡수할 수 있는 재료를 사용하면 쉽게 해결할 수 있지만 전자장비에 유해한 전자파로부터 보호하기 위해서는 전자장비함으로 전자파가 유입되지 못하도록 하여야 한다.In order to protect electronic equipment from vibration or shock, it can be easily solved by using shock absorbers or materials that can effectively absorb shocks in the electronic equipment. do.

전자장비함은 기본적으로 전자파를 차단할 수 있는 재료를 사용하여 완전히 밀폐된 구조로 제작되므로 전자장비함에 수납된 전자장비를 전자파로부터 보호할 수 있으나 전자장비함을 개방하기 위하여 설치된 덮개와 전자장비함 사이에는 미세한 틈새가 발생되어 이 틈새로 전자파가 유입되어 전자장비의 본래기능이 저하되는 문제점이 있다.The electronic equipment box is basically made of a completely enclosed structure using materials that can block electromagnetic waves, so that the electronic equipment stored in the electronic equipment box can be protected from electromagnetic waves, but between the cover and the electronic equipment box installed to open the electronic equipment box. There is a problem in that a minute gap is generated and electromagnetic waves are introduced into the gap to degrade the original function of the electronic equipment.

따라서 전자장비함에 설치되는 덮개는 전자장비함과의 기밀성을 유지하기 위하여 전자장비함과 덮개 사이에 가스켓을 삽입한 후 덮개의 외측에서 다수의 볼트를 이용하여 체결함으로써 이러한 문제를 해결하였다.Therefore, the cover installed in the electronic equipment box solved this problem by inserting a gasket between the electronic equipment box and the cover to maintain the airtightness with the electronic equipment box and then fastening by using a plurality of bolts on the outside of the cover.

그러나, 전자파를 차단하기 위하여 전자장비함에 설치되는 덮개에 너무많은 볼트를 사용함으로써 덮개를 개방시에는 볼트를 모두 해제해야 하므로 덮개를 해제하는 시간이 너무 많이 소요되는 문제점이 있다.However, the use of too many bolts on the cover installed in the electronic equipment box to block the electromagnetic wave has a problem that takes too much time to release the cover because the bolts must be released when opening the cover.

이렇게 덮개를 해제하는데 걸리는 시간을 단축하기 위하여 수개의 볼트만으로 체결하면 전자장비함과 덮개 사이에 틈새가 발생되는 문제점이 있다.In order to shorten the time taken to release the cover, there is a problem that a gap is generated between the electronic equipment box and the cover when only a few bolts are fastened.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 전자장비함과 설치되는 덮개를 간단한 방법으로 탈장착할 수 있고, 아울러 전자장비함과 덮개사이에 기밀성도 유지할 수 있도록 하는 전자장비함 덮개를 제공함에 있다.The present invention is to solve the problems as described above, to provide a cover for the electronic equipment compartment and the cover to be installed in a simple way, and also to maintain the airtightness between the electronic equipment compartment and the cover. Is in.
