본 고안은 각종 전자통신 장비의 정전기(ESD)(Electro Static Discharge) 방지용 이젝터에 관한 것으로 특히 인쇄 회로기판을 착탈시 이젝터에서 발생하는 정전기를 정전기 방지용 핀을 이용하여 정전기를 방지할 수 있도록 한 것이다.The present invention relates to an electrostatic discharge (ESD) preventive ejector of various electronic communication equipment, in particular to prevent the static electricity generated by the ejector when the printed circuit board is attached and detached by using an antistatic pin.
일반적으로 전자통신 장비는 제1도 및 제2도에 도시한 바와 같이 사각틀체의 쉘프(3)와, 쉘프(3) 내에 밀집 설치되는 인쇄 회로기판(2)과, 상기 인쇄 회로기판(2)의 전면에 고정 설치되며 그 하단에 이젝터(1)를 구비한 전면판(4)과, 가이드(5) 면으로 구성되어 있다.In general, an electronic communication device includes a rectangular shelf (3), a printed circuit board (2) densely installed in the shelf (3), and the printed circuit board (2). It is fixed to the front of the front plate 4 having an ejector (1) at the bottom and consists of a guide (5) surface.
이와 같이 구성된 전자통신 장비에서 사용자가 필요에 의해서 인쇄 회로기판(2)을 착탈하는 경우 순간적으로 이젝터(1)에서 정전기가 발생하는 경우가 종종 있어서 사용자가 안전하게 작업을 수행하지 못하는 경우가 발생하였던 것이다.When the user detaches the printed circuit board 2 as necessary in the electronic communication device configured as described above, static electricity is sometimes generated in the ejector 1, and thus, the user cannot safely perform the work. .
본 고안은 상기와 같은 종래의 문제점을 해소하기 위하여 안출한 것으로서, 인쇄 회로기판을 착탈시 이젝터에서 발생하는 정전기를 정전기 방지용 핀을 이용하여 정전기를 방지할 수 있도록 한 전자통신 장비의 정전기 방지용 이젝터를 제공코자 함을 그 목적으로 하는 것이다.The present invention has been made in order to solve the above-mentioned conventional problems, the anti-static ejector of the electronic communication equipment to prevent the static electricity generated by the ejector when the printed circuit board detachable by using the antistatic pins The purpose is to provide.
이러한 목적 달성을 위한 본 발명을 첨부된 실시예의 도면에 따라 상세히 설명하면 다음과 같다.When the present invention for achieving this purpose will be described in detail according to the accompanying drawings of the embodiments as follows.
제3도(a)(b)(c) 및 제4도에 도시한 바와 같이 사각틀체의 쉘프(3)와, 상기 쉘프(3)내에 밀접 설치되는 인쇄 회로기판(2)과, 상기 인쇄 회로기판(2)의 전면에 고정 설치되며 그 하단에 이젝터(1)를 구비한 전면판(4)과, 가이드(5)로 구성되는 전자통신 장비에 있어서, 상기 이젝터(1)의 저면 소정부위에는 구멍(6)이 형성되며, 상기 구멍(6)에는 하우징(9) 내에 스프링(8)으로 탄력 설치된 정전기 방지용 핀(7)이 삽입되어 핀(7)의 일단이 가이드면(5)에 접지 되도록 구성되어지는 것이다.As shown in Figs. 3A, 4B and 4C, the shelf 3 of a rectangular frame, a printed circuit board 2 closely installed in the shelf 3, and the printed circuit In an electronic communication device comprising a front plate 4 fixedly mounted on the front surface of the substrate 2 and having an ejector 1 at a lower end thereof, and a guide 5, a predetermined portion of the bottom surface of the ejector 1 A hole 6 is formed, and an antistatic pin 7 elastically installed with a spring 8 is inserted into the hole 9 so that one end of the pin 7 is grounded to the guide surface 5. It is constructed.
상기와 같이 구성된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
쉘프(3)에 장착되어져 있는 인쇄 회로기판(2)을 테스트 및 기능 보완을 위해 착·탈을 시도하게 되는데, 모든 사용자는 이젝터(1)의 상단부(A)를 잡고 인쇄 회로기판(2)을 착탈한다. 이때 이젝터(1)의 상단부(A) 또는 이젝터(1) 자체에서는 정전기가 종종 발행하게 되는데, 상기 이젝터(1)의 저면 소정위치의 구멍(6)에는 정전기 방지용 핀(7)을 스프링(8)과 하우징(9)을 이용하여 상기 구멍(6)에 장착시키고, 상기 정전기용 핀(7)은 스프링(8)의 탄력으로 가이드(5)면에 접지 되게 하였으므로 이젝터(1)에서 발생되는 상기 가이드(5)면을 타고 외부로 빠져 나가버리게 되므로 이젝터(1)에는 정전기가 남아있지 않게 되는 것이다.Attempts to attach and detach the printed circuit board (2) mounted on the shelf (3) to test and complement the function, all users hold the upper end (A) of the ejector (1) to hold the printed circuit board (2) Remove it. At this time, the static electricity is often issued at the upper end A of the ejector 1 or the ejector 1 itself, and the antistatic pin 7 is provided in the hole 6 at a predetermined position on the bottom surface of the ejector 1. And the housing 9 to be mounted in the hole 6, and the electrostatic pin 7 is grounded on the surface of the guide 5 by the elasticity of the spring 8, so that the guide generated from the ejector 1 (5) The surface will be taken out to the outside, so that no static electricity will remain in the ejector (1).
이상과 같이 본 고안은 인쇄 회로기판을 착탈시 이젝터에서 발생되는 정전기를 정전기 방지용 핀을 이용하여 정전기를 방지할 수 있도록 한 것으로 매우 실용성 있는 고안인 것이다.As described above, the present invention is designed to prevent the static electricity generated by the ejector when the printed circuit board is attached and detached using an antistatic pin, which is a very practical design.
