Here, the shield member 120 is generally provided as a conductor and grounded through the casing 110 to shield EMI (Electro Magnetic Interference).

결합장치(130)는 쉴드부재(120)에 형성된 결합부(131)와, 결합부(131)와 대응하여 인쇄회로기판(115)에 마련된 체결지지부재(133)와, 결합부(131)로부터 삽입되어 체결지지부재(133)와 체결되는 체결부재(132)를 포함한다.The coupling device 130 includes a coupling part 131 formed on the shield member 120, a fastening support member 133 provided on the printed circuit board 115 in correspondence with the coupling part 131, and a coupling part 131.

It includes. Thus, the fastening member 32 passes through the coupling part 31 of the shield member 20 and then is fastened to the boss part 34b through the fastening hole 34a. Here, the boss portion 34b is preferably provided in a tapered shape so that the fastening member 32 penetrating the coupling portion 31 is easily fastened to the support body 34.

걸림부(35)는 인쇄회로기판(15)과 분리 가능하게 결합되며, 인쇄회로기판(15)에는 걸림부(35)가 삽입되는 걸림부삽입공(16)이 형성되어 있다. 걸림부(35)는 지지본체(34)로부터 하향 연장되어 인쇄회로기판(15)의 일측면에 걸리는 스토퍼(38)와, 스토퍼(38)로부터 하향 연장되고 인쇄회로기판(15)의 타측면에 걸리는 후크부(39)를 포함한다. The engaging portion 35 is detachably coupled to the printed circuit board 15, and the engaging portion insertion hole 16 into which the engaging portion 35 is inserted is formed in the printed circuit board 15. The catching part 35 extends downward from the support body 34 and stops on one side of the printed circuit board 15, and extends downward from the stopper 38 and on the other side of the printed circuit board 15. The hook portion 39 is included.

스토퍼(38)는 인쇄회로기판(15)의 상면에 접촉하여 체결지지부재(33)가 걸림부삽입공(16)으로 하향 진입되는 것을 방지하고, 후크부(39)는 인쇄회로기판(15)의 저면에 접촉하여 체결지지부재(33)가 걸림부삽입공(16)으로부터 상향 이탈되는 것을 방지한다. The stopper 38 is in contact with the upper surface of the printed circuit board 15 to prevent the fastening support member 33 from entering downward to the engaging portion insertion hole 16, the hook portion 39 is the printed circuit board 15 In contact with the bottom surface of the fastening support member 33 prevents the upward departure from the locking portion insertion hole (16).

여기서, 걸림부(35)는 지지본체(34)의 양측에 대향되도록 마련된 제1걸림부(36) 및 제2걸림부(37)를 포함하고, 이에 따라 지지본체(34)가 인쇄회로기판(15)에 대해 수평이 유지될 수 있다.Here, the catching part 35 includes a first catching part 36 and a second catching part 37 provided to face both sides of the support body 34, and thus the support body 34 is a printed circuit board ( Can be kept horizontal with respect to 15).

제1걸림부(36) 및 제2걸림부(37)에는 각각 한 쌍의 스토퍼(38)와 후크부(39)가 마련된다. 이 때, 걸림부삽입공(16)은 후크부(39)와 대응하여 인쇄회로기판(15)에 관통 형성되는 것이 바람직하다. The first catching portion 36 and the second catching portion 37 are provided with a pair of stoppers 38 and a hook portion 39, respectively. At this time, the engaging portion insertion hole 16 is preferably formed through the printed circuit board 15 to correspond to the hook portion (39).

여기서, 후크부(39)에 솔더링(40)(Soldering, 일명 납땜이라 함) 등의 작업을 함으로써 체결지지부재(33)를 인쇄회로기판(15)에 고정시킬 수 있다. 이 때, 솔더링(40) 작업을 작업자가 수작업으로 할 수도 있으나, 체결지지부재(33)가 걸림부(35)에 의해 인쇄회로기판(15)으로부터 이탈되지 않으므로 인쇄회로기판(15)을 자동납땜기에 투입하여 자동으로 솔더링(40) 작업을 할 수도 있다. 자동납땜기를 사용하여 작업한 경우에는 작업시간이 단축되므로 생산성이 향상된 전기전자기기(1)를 제공할 수 있다. Here, the fastening support member 33 may be fixed to the printed circuit board 15 by performing a work such as soldering 40 (soldering, so-called soldering) on the hook portion 39. In this case, the soldering 40 may be manually operated by the worker. However, since the fastening support member 33 is not separated from the printed circuit board 15 by the catching part 35, the printed circuit board 15 may be automatically soldered. It can also be put into the automatic soldering 40 work. In the case of working with an automatic soldering machine, the working time can be shortened, so that the productivity can be improved.

또한, 인쇄회로기판(15)에 체결지지부재(33)가 견고히 결합되므로 체결지지부재(33)가 인쇄회로기판(15)으로부터 유동되는 것이 방지될 수 있다. 따라서, 체결부재(32)와 체결지지부재(33) 사이의 결합력에 의해 인쇄회로기판(15)과 쉴드부 재(20)가 견고히 결합되므로, 인쇄회로기판(15)으로부터의 전자파가 쉴드부재(20)로 전도되어 접지됨으로써 전자파가 효율적으로 차폐될 수 있다.In addition, since the fastening support member 33 is firmly coupled to the printed circuit board 15, the fastening support member 33 may be prevented from flowing from the printed circuit board 15. Accordingly, since the printed circuit board 15 and the shield member 20 are firmly coupled by the coupling force between the fastening member 32 and the fastening support member 33, electromagnetic waves from the printed circuit board 15 are shielded ( Electromagnetic wave can be efficiently shielded by being conductive and grounded to 20).

이러한 구성에 의하여, 본 발명에 따른 전기전자기기(1)의 인쇄회로기판(15)과 쉴드부재(20)의 결합과정을 살펴보면 다음과 같다. With this configuration, the coupling process of the printed circuit board 15 and the shield member 20 of the electric and electronic device 1 according to the present invention will be described.
