Description
본 고안은 통신전자장비의 수용공간에 보조회로기판을 장착하기 위한 장치에 관한 것으로, 특히 보조회로기판의 장착하기 위한 작업공수를 절감시킬 수 있도록 된 통신전자장비의 보조회로기판 고정장치에 관한 것이다.The present invention relates to an apparatus for mounting an auxiliary circuit board in a receiving space of communication electronic equipment, and more particularly, to an auxiliary circuit board fixing device of communication electronic equipment that can reduce the labor for mounting the auxiliary circuit board. .
일반적으로, 통신전자장비 예컨대, 통신기지단말기나 무선전화기 등에는 각종 회로문양이 인쇄된 메인회로기판과 무선주파수를 송신하기 위한 무선주파수회로기판(RF PCB, 이하 보조회로기판이라 함)이 설치되는데, 이러한 보조회로기판은 지지브래킷을 매개로하여 통신전자장비내에 고정설치된다.In general, communication electronic equipment, such as a communication base terminal or a wireless telephone, is provided with a main circuit board printed with various circuit patterns and a radio frequency circuit board (RF PCB) for transmitting radio frequency (hereinafter referred to as an auxiliary circuit board). The auxiliary circuit board is fixedly installed in communication electronic equipment through a support bracket.
여기서, 통신전자장비의 지지브래킷들은 회로기판들을 탄력적으로 지지하게 되는 지지기능과 접지판(ground pad)으로 면접촉되면서 회로기판을 접지시키는 접지기능을 수행하게 된다.Here, the support brackets of the communication electronic equipment perform a grounding function of grounding the circuit board while being in surface contact with a ground pad.
즉, 상기한 기능을 수행할 수 있도록 된 종래의 통신전자장비는 도 1의 도면에 도시된 바와 같이, 통신전자장비(100)의 수용공간에 각종 회로문양이 인쇄된 메인회로기판(110)이 장착되며, 메인회로기판(110)의 상면에 소정형상의 지지브래킷(120)을 통해 보조회로기판(130)이 설치되어 있다.That is, in the conventional communication electronic equipment capable of performing the above function, as shown in the drawing of FIG. 1, the main circuit board 110 in which various circuit patterns are printed in the accommodation space of the communication electronic equipment 100 is provided. The auxiliary circuit board 130 is mounted on the upper surface of the main circuit board 110 through a support bracket 120 having a predetermined shape.
그리고, 지지브래킷(120)의 몸체 하부면에 메인회로기판(110)의 관통공으로 삽입된 상태에서 너트(121)로 체결되는 돌출턱(122)이 볼록하게 형성되면서, 상부면에 보조회로기판(130)이 밀착된 상태에서 스크류(123)로 체결되는 체결홈(124)이 오목하게 형성되어 있다.In addition, the protruding jaw 122 is fastened to the nut 121 by being inserted into the through hole of the main circuit board 110 in the lower surface of the body of the support bracket 120, and the auxiliary circuit board ( The fastening groove 124 fastened by the screw 123 in the state in which the 130 is in close contact is concave.
따라서, 통신전자장비(100)의 수용공간으로 회로기판을 장착하는 과정에서 예컨대, 메인회로기판(110)의 관통공으로 지지브래킷(120)의 돌출턱(122)을 삽입한 후에 너트(121)로 체결하고, 지지브래킷(120)의 상면으로 보조회로기판(130)을 안착시킨 상태에서 체결홈(124)으로 스크류(123)를 나사결합하여 보조회로기판(130)을 고정하게 되는 것이다.Therefore, in the process of mounting the circuit board to the receiving space of the communication electronic device 100, for example, the insertion projection 122 of the support bracket 120 into the through hole of the main circuit board 110 and then into the nut 121 When the auxiliary circuit board 130 is seated on the upper surface of the support bracket 120, the screw 123 is screwed to the fixing groove 124 to fix the auxiliary circuit board 130.
그런데, 통신전자장비(100)의 수용공간에 각각의 메인회로기판(110)과 보조회로기판(130)을 장착하기 위해서는, 예컨대 지지브래킷(120)에 형성된 돌출턱(122)을 수작업으로 너트로 체결함과 동시에 체결홈(124)을 일일이 스크류로 체결하게 되므로, 메인회로기판(110)과 보조회로기판(130)을 장착하기 위한 조립과정이 지연되는 문제점이 있었다.However, in order to mount each of the main circuit board 110 and the auxiliary circuit board 130 in the accommodation space of the communication electronic device 100, for example, the projection jaw 122 formed on the support bracket 120 by hand with a nut. Since the fastening groove 124 is fastened with screws at the same time, the assembly process for mounting the main circuit board 110 and the auxiliary circuit board 130 is delayed.
그리고, 지지브래킷(120)의 상면과 보조회로기판(130)의 접지판이 상호 면접촉된 상태로 접지기능이 수행되므로, 회로기판(110,130)이 손상을 입을 수 있다는 문제점이 있었다.In addition, since the grounding function is performed while the upper surface of the support bracket 120 and the ground plate of the auxiliary circuit board 130 are in contact with each other, there is a problem that the circuit boards 110 and 130 may be damaged.
또한, 지지브래킷(120)의 돌출턱(122)과 체결홈(124)의 형상을 기계가공으로 형성시키므로, 지지브래킷(120)의 몸체를 형성시키기 위한 제조경비가 상승되는 문제점이 있었다.In addition, since the shape of the protruding jaw 122 and the fastening groove 124 of the support bracket 120 is formed by machining, there is a problem that the manufacturing cost for forming the body of the support bracket 120 is increased.
이에, 본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 메인회로기판과 보조회로기판을 상호 고정하기 위한 지지브래킷의 구조를 변경하여, 회로기판들의 접지기능을 향상시키게 될 뿐만 아니라 회로기판의 설치공수를 단축시킬 수 있도록 된 통신전자장비의 보조회로기판 고정장치를 제공하는 데에 그 목적이 있다.Accordingly, the present invention was devised to solve the above problems, and by changing the structure of the support bracket for fixing the main circuit board and the auxiliary circuit board to each other, to improve the grounding function of the circuit boards as well as the circuit It is an object of the present invention to provide an auxiliary circuit board fixing device for communication electronic equipment that can shorten the installation time of the board.
