본 고안은 통신기기 셀프에 관한 것으로, 더욱 상세하게는 셀프의 전면판과 인쇄회로기판의 결합을 용이함과 동시에 인쇄회로기판에 인가되는 과부하를 방지하기 위한 접지를 구현하는 셀프의 전면판과 인쇄회로기판의 결합구조에 관한 것이다.The present invention relates to a communication device self, and more particularly, the front plate and the printed circuit of the self to implement the ground to prevent the overload applied to the printed circuit board and at the same time facilitate the coupling of the front plate and the printed circuit board of the self. It relates to a bonding structure of the substrate.

일반적으로 통신기기는 전자부품들이 배열 설치된 다수개의 유니트들이 하나의 시스템으로 이룬 셀프를 이루고, 이러한 셀프들은 시스템별로 랙의 내부에 적층되어 설치된다. 이와 같이 셀프들이 정돈되면 외부로부터의 충격을 방지하고 내부의 전자부품들의 작동에 의해 발생된 전자파로 인하여 다른 통신기기의 작동에 영향을 주지 않도록 하기 위해 도어를 닫아 외부와 차단하게 된다.In general, a communication device forms a shelf consisting of a plurality of units in which electronic components are arranged in a single system, and these shelves are stacked and installed inside the rack for each system. As such, when the self-assembly is arranged, the door is closed from the outside in order to prevent an impact from the outside and to not affect the operation of other communication devices due to the electromagnetic waves generated by the operation of the internal electronic components.

이와 같이 구성된 랙의 내부에 설치된 셀프를 첨부된 도면을 참조하여 살펴보면 다음과 같다.Looking at the self installed in the rack configured as described above with reference to the accompanying drawings as follows.

도 1을 참조하면, 도 1은 일반적인 셀프의 구조를 나타낸 셀프의 사시도로서, 셀프의 구조는 전·후부 상하에 횡으로 설치된 4개의 프레임(10)과, 4개의 프레임(10)의 양측에 나사결합되어 셀프의 양측면을 이루는 측판(17)과, 전후 프레임(10)을 연결하는 다수개의 가이드 레일(20)과, 유니트 커넥터(34)를 다수개 형성하여 셀프의 배면을 구성하는 후측면 인쇄회로기판(18) 및 내부에 다수개 배설되는 유니트(30)로 구성된다. 이때, 유니트(30)는 전기 회로가 배치된 인쇄회로기판(60a)과, 인쇄회로기판(60a)의 전면에 부착되는 전면판(40a)과, 전면판(40a)의 상하부에 설치되어 유니트(30)를 착탈시킬 때 용이하도록 한 이젝터(35) 및 유니트(30)의 후단부에 설치되어 후측면 메인인쇄회로기판(18) 커넥터(19)에 접속되는 유니트 커넥터(34)가 구비되어 있다.Referring to FIG. 1, FIG. 1 is a perspective view of a shelf illustrating a structure of a common shelf. The structure of the shelf includes four frames 10 installed horizontally above and below the front and rear sides, and screws on both sides of the four frames 10. Rear printed circuit that forms a rear surface of the shelf by forming a rear side of the shelf by combining a side plate 17 which is coupled to form both sides of the shelf, a plurality of guide rails 20 connecting the front and rear frames 10, and a unit connector 34. It consists of the board | substrate 18 and the unit 30 arrange | positioned several inside. At this time, the unit 30 is provided with a printed circuit board 60a on which an electric circuit is disposed, a front plate 40a attached to the front surface of the printed circuit board 60a, and upper and lower portions of the front plate 40a. The ejector 35 and the unit connector 34 which are provided at the rear end of the unit 30 so as to be easily detached and attached to the rear side main printed circuit board 18 connector 19 are provided.

And the ground surface 62a is formed in the outer periphery of the fastening hole 64a.

이와 같이 구성된 유니트(30)는 도 1에 도시된 셀프에 조립시키기 전에 전면판(40b)의 슬라이드홈(42)에 인쇄회로기판(60a)을 재치시킨 후에 나사구멍(43)과 체결구멍(64a)을 통해 나사(70)를 체결시켜 조립하게 된다.The unit 30 configured as described above has a screw hole 43 and a fastening hole 64a after the printed circuit board 60a is placed in the slide groove 42 of the front plate 40b before assembling to the shelf shown in FIG. By assembling the screw 70 through.

그러나, 전면판(40b)에 인쇄회로기판(60a)을 조립할 때 인쇄회로기판(60a) 체결구멍(64a)의 외주면에 그라운드면(62a)이 형성되어 있기 때문에 나사(70)가 체결될 때 그라운드면(62a)이 파손되는 경우가 발생되어 인쇄회로기판(60a)에 실장된 회로에 인가되는 과전류나 과전압이 외부로 접지되지 못함에 됨에 따라 회로적인 소자들이 손상되는 문제점이 발생되었다.However, when assembling the printed circuit board 60a to the front plate 40b, the ground surface 62a is formed on the outer circumferential surface of the fastening hole 64a of the printed circuit board 60a. When the surface 62a is damaged and the overcurrent or overvoltage applied to the circuit mounted on the printed circuit board 60a is not grounded to the outside, the circuit elements are damaged.

따라서, 본 고안은 상술된 문제점을 해결하기 위해 안출된 것이다.Therefore, the present invention has been devised to solve the above-mentioned problem.

본 고안의 목적은 셀프의 전면판과 인쇄회로기판이 결합이 용이함과 동시에 과부하에 따른 접지를 용이하게 할 수 있는 인쇄회로기판의 결합구조를 제공하는데 있다.An object of the present invention is to provide a coupling structure of a printed circuit board that is easy to combine the front plate and the printed circuit board of the self and at the same time easy to ground due to overload.
