본 발명은 통신장비(교환기, 전송장치, 무선통신기기등)용 셀프(shelf)의 전면판넬(front panel)에 관한 것으로서, 특히 다수개의 전자회로기판(printed circuit board assembly)이 설치되어 운전되는 전자통신 시스템장비에서 발생하는 전자파장애를 방지하도록 전자회로기판이 부착되는 전면판넬의 구조를 변경하여 제품의 신뢰성을 추구한 셀프의 전면판넬구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front panel of a shelf for communication equipment (exchangers, transmitters, wireless communication devices, etc.), in particular a plurality of electronic circuit boards (printed circuit board assembly) is installed and operated The present invention relates to a self-contained front panel structure in which the reliability of a product is pursued by changing the structure of the front panel to which an electronic circuit board is attached to prevent electromagnetic interference generated from communication system equipment.
일반적으로 통신장비용 셀프는 제1도에 도시되었듯이, 그의 구성을 대별해 보면, 상부프레임(10 : upper frame)과 하부프레임(20 : down frame) 및 사이드판넬(30a, 30b : side panel)의 조합으로 기본골격을 구성하며, 조립의 강도를 보강하기 위하여 상기 사이드판넬(30a, 30b)의 양측면상에 고정용 브라켓(40a, 40b : bracket)을 나사로 체결하며, 필요에 따라서 부가장비를 실장하기 위하여 부가장비 실장부가 형성되고, 전면 또는 측면에 도어(door) 또는 커버(cover)를 부착할 수 있는 캐비넷형(cabinet type)으로 되어 있다.In general, as shown in FIG. 1, self-assembly for communication equipment is roughly divided into the upper frame (10: upper frame) and the lower frame (20: down frame) and side panels (30a, 30b: side panel). Combining the basic skeleton by the combination of, and fastening the fixing brackets (40a, 40b: bracket) on both sides of the side panel (30a, 30b) with screws to reinforce the strength of the assembly, mounting additional equipment as necessary An additional equipment mounting portion is formed in order to form a cabinet type to which a door or a cover can be attached to a front side or a side surface thereof.
상기 셀프(100)의 기본구성요소중 상부프레임(10)과 하부프레임(20)은 상호 상하좌우 대칭구조로서, 기본골격을 지지함과 동시에 고정하며, 통신장비 실장시, 이의 하중과 셀프자체의 자중을 받으면서 각 프레임의 위치 및 외곽치수를 좌우하는 중요한 기능을 수행한다.The upper frame 10 and the lower frame 20 of the basic components of the shelf 100 are symmetrical structures up, down, left, and right of each other, and at the same time to support and fix the basic skeleton, when mounting the communication equipment, its load and self It performs the important function which influences the position and the outer dimension of each frame under the weight.
더욱이, 상기 상부프레임(10)과 하부프레임(20)상에는 전자회로기판(63)이 장치된 유니트(u)를 실장하는 경우, 부드럽게 밀어 넣을 경우 슬라이딩되어 실장되도록 다수개의 가이드 지지대와 그 위에 가이드레일(70)이 직각방향으로 간격지게 설치되어 있으며, 각각의 유니트(u)가 가이드레일(70)을 따라 부드럽게 슬라이딩 가능하도록 각각의 유니트(u)의 하부에 이젝터(61)를 설치하여 유니트(u)의 착탈을 가능하게 한다.Furthermore, when mounting the unit (u) on which the electronic circuit board 63 is mounted on the upper frame 10 and the lower frame 20, a plurality of guide supports and guide rails thereon so as to slide and mount when gently pushed in. 70 is spaced apart at right angles, and the ejector 61 is installed at the bottom of each unit u so that each unit u can slide smoothly along the guide rail 70. I let you put on and take off).
이때, 상기 유니트(u)의 전방에 설치되는 전면판넬(60)의 구조에서, 제2도에 도시되었듯이, 상기 알루미늄재질의 전면판넬(60)에는 전자회로기판(63)이 부착되어 지는 곳으로, 정전기차폐를 고려하여 각 전면판넬(60)의 일면(65b)에는 다른 전면판넬의 일면(65a)과의 틈새를 방지하기 위하여 구멍을 형성하여 일정 형상의 가스켓(64)을 설치하며, 상기 가스켓(64)은 전면판넬(60)간의 틈새를 막아주게 된다.At this time, in the structure of the front panel 60 installed in front of the unit (u), as shown in Figure 2, where the electronic circuit board 63 is attached to the front panel 60 of the aluminum material In consideration of the electrostatic shielding, one surface 65b of each front panel 60 is formed with a hole to prevent a gap with one surface 65a of the other front panel to install a gasket 64 having a predetermined shape. The gasket 64 prevents a gap between the front panel 60.
그러나, 상기 기술한 바와같이, 기존의 전면판넬의 구조로는 전면방향으로 방사되는 전자파는 차폐가 가능한 구조이나, 전면판넬에 부착되는 이젝터의 타입에 따라서 전면판넬이 노칭되는 경우에는 전방으로 방사되는 전자파를 완벽하게 차폐하기가 어려운 문제점이 발생한다.However, as described above, in the conventional front panel structure, electromagnetic waves radiated in the front direction can be shielded, but when the front panel is notched according to the type of ejector attached to the front panel, it is radiated forward. It is difficult to shield electromagnetic waves completely.
또한, 다수의 전자회로기판이 실장되는 셀프내에서는 상기 전자회로기판간의 차폐, 즉 전자회로기판의 발광다이오드나 스위치 및 콘넥터등이 접속된 방향과 그 반대방향으로 납땜이 형성되는 방향에서 상기 납땜이 형성되는 방향과 다른 옆쪽의 방향과의 차폐가 되어 있지 않음으로 인하여 전자회로기판 전체에 측방향으로 방사되는 전자파에 대해서는 차폐가 어려운 문제점이 발생한다.In a self-mounted electronic circuit board in which a plurality of electronic circuit boards are mounted, the soldering may be performed in a shielding between the electronic circuit boards, that is, in a direction in which soldering is formed in a direction opposite to that of a light emitting diode, a switch, and a connector of the electronic circuit board. Shielding is difficult for electromagnetic waves radiated laterally to the entire electronic circuit board because shielding is not performed between the formed direction and the other side direction.

To provide.
상기한 목적을 달성하기 위하여, 본 발명은 통신장비용 셀프에서 전자회로기판의 전방면만을 커버하는 전면판넬구조에 있어서, 전자회로기판의 전방면을 커버하도록 플라스틱재질의 전면판넬을 설치하고, 상기 플라스틱재질의 전면판넬에 길이방향으로 연장된 가스킷 고정용 스트립을 핀으로 부착하여 가스킷을 설치하고, 상기 전자회로기판의 납땜면을 커버하여 상기 전자회로기판의 납땜면으로부터 발생하는 전자파를 차폐하도록 다수개의 스페이서를 간격지게 설치하여 알루미늄재질의 전면판넬을 상기 전면판넬에 부착함을 특징으로한다.In order to achieve the above object, the present invention provides a front panel structure that covers only the front surface of the electronic circuit board in the self-communication equipment, the front panel of the plastic material to cover the front surface of the electronic circuit board, A gasket is installed by attaching a gasket fixing strip extending in the longitudinal direction to the front panel of plastic material with a pin, and covering the solder surface of the electronic circuit board to shield electromagnetic waves generated from the solder surface of the electronic circuit board. It is characterized in that the front panel of the aluminum material is attached to the front panel by installing two spacers spaced apart.
