이때, 상기 회로기판(120)의 탄력부(122)는 상기 양측 케이스(100, 110)의 후크(102)결합 시, 일측 케이스(100)의 가압부(125)로 가압되어 휘어지면서, 상기 가압부(125) 및 상기 지지부(130)에 대해 탄력을 제공하며, 상기 양측 케이스(100, 110)는 회로기판(120)의 외측으로 향하는 상기 회로기판(120)의 탄력을 받게 된다.At this time, the elastic portion 122 of the circuit board 120 is pressed by the pressing portion 125 of the one side case 100 when the hooks 102 of the case 100, 110 both sides, the bending, The elasticity of the part 125 and the support part 130 is provided, and both case cases 100 and 110 receive the elasticity of the circuit board 120 toward the outside of the circuit board 120.

즉, 상기 회로기판(120)의 탄력부(122)에 의한 탄력은 상기 일측 케이스 (100)에 제공된 후크(102)에 전달되어, 상기 후크(102)가 타측 케이스(110)에 형성된 결합공(112)에서 유동하는 것을 방지하므로, 양측 케이스(100, 110)의 후크결합(140)이 상기 후크(102)가 받는 탄력의 의해 강화된다.That is, the elasticity of the resilient portion 122 of the circuit board 120 is transmitted to the hook 102 provided on the one side case 100, the coupling hole formed in the other case 110, the hook 102 ( Since the flow is prevented from 112, the hook coupling 140 of both cases (100, 110) is strengthened by the elasticity received by the hook (102).

이때, 양측의 케이스(100, 110)는 후크(102)의 일면부(102a)가 상기 결합공(112)을 제공하는 일측 케이스(100)에 탄력적으로 지지되어 상기 후크(102)의 유동 없이 조립된 형태를 유지한다.At this time, the case (100, 110) of both sides is elastically supported by one side portion (100a) of the hook 102, the one side case 100 providing the coupling hole 112 is assembled without the flow of the hook (102) Keep the form intact.

여기서, 상기 회로기판(120)은 상기 탄력부(122)를 형성하는 절곡통공(132)을 포함하고, 상기 탄력부(122)는 상기 회로기판(120)의 상부에 제공되며, 상기 가압부(125)는 상기 탄력부(122)에 대해 수직으로 상기 일측 케이스(100)에 배치되고, 상기 지지부(130)는 상기 가압부(125)의 하부에서 상기 회로기판(120)에 대해 수직으로 상기 타측 케이스(110)에 배치된다.Here, the circuit board 120 includes a bent through hole 132 to form the elastic portion 122, the elastic portion 122 is provided on the circuit board 120, the pressing portion ( 125 is disposed in the one side case 100 perpendicular to the elastic part 122, and the support part 130 is perpendicular to the circuit board 120 at the lower portion of the pressing part 125. It is disposed in the case 110.

또한, 상기 가압부(125)와 상기 지지부(130)의 수평거리(d)는 상기 회로기판(120)의 두께보다 얇게 형성됨으로써, 상기 회로기판(120)이 상기 양측 케이스(100, 110) 사이에 배치될 때, 상기 회로기판(120)의 탄력부(122)는 상기 가압부(125)에 의해 가압되어 탄력을 발생시킨다. In addition, the horizontal distance (d) of the pressing unit 125 and the support 130 is formed thinner than the thickness of the circuit board 120, so that the circuit board 120 between the case 100, 110 When disposed in the, the elastic portion 122 of the circuit board 120 is pressed by the pressing portion 125 to generate elasticity.

따라서 상기와 같이 구성된 본 발명은 케이스의 내부로 회로기판이 배치되고 케이스가 조립될 때, 양측 케이스가 서로 반대방향으로 가압되는 힘을 상기 회로기판이 제공하여 케이스의 후크결합이 강화되고, 케이스의 외력에 의한 체결력을 감 소시켜 후크결합의 훼손을 방지하는 효과를 얻을 수 있다.Therefore, in the present invention configured as described above, when the circuit board is disposed inside the case and the case is assembled, the circuit board provides the force that both sides press in opposite directions to each other to strengthen the hook coupling of the case, By reducing the fastening force by the external force can be obtained to prevent the damage of the hook coupling.
