It is attached to one side wall part of the said heat radiating member 3 via (2).

즉, 고정 부재(2)의 상부에 형성된 걸림 구조에 의해, 상기 부회로기판(1)이 고정 되고, 상기 훅크 구조는 상기 방열부재(3)의 측벽부에 취부되어 상기 부회로기판(1)을 지지한다That is, the sub-circuit board 1 is fixed by the locking structure formed on the fixing member 2, and the hook structure is mounted on the side wall of the heat-dissipating member 3 so that the sub-circuit board 1 is fixed. Support

그런데, 상기한 고정 부재(2)의 구조에 의하면, 작업자가 부회로기판(1)을 방열 부재(3)에 고정하기 위해, 부회로기판(1)의 네 모서리 부분에 상기 고정 부재(2)를 일일히 취부한 후, 이를 다시 상기 방열 부재(3)에 장착해야 하므로, 조립 공정이 복잡해지고, 작업 자가 조립 작업을 하는데 있어서, 번거로움을 받는 문제점이 있었다.However, according to the structure of the fixing member 2 described above, in order for an operator to fix the subcircuit board 1 to the heat dissipation member 3, the fixing member 2 is formed at four corners of the subcircuit board 1. After mounting all of them, it must be mounted on the heat dissipation member 3 again, the assembly process is complicated, there is a problem in that the worker is in trouble in the assembly work.

이에 본 고안은 상기의 문제점을 해결하기 위해 안출한 것으로서, 부회로기판을 방열 부재에 장착되도록 하는 고정 부재의 구조를 개선하여, 부품수를 줄이고, 조립 공정을 단순화하기 위한 모니터의 회로기판 고정기를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by improving the structure of the fixing member for mounting the sub-circuit board to the heat dissipation member, to reduce the number of parts, simplify the assembly process of the monitor circuit board The purpose is to provide.

상기한 바의 목적을 달성하기 위해 본 고안은, 모니터의 주회로기판에 실장된 플라이백 변압기를 둘러싸고 있는 방열체의 일측벽부에 부회로기판을 장착하는 구조에 있어서, 양측부에 아래로 경사지게 돌출된 받침판이 형성된 몸체부와, 상기 몸체부의 상부에 부회로기판을 고정하기 위해 형성된 고정 수단, 그리고, 상기 몸체부와 상기 부회로기판이 방열부재의 일측벽부에 지지되도록 상기 몸체부의 하부에 형성된 지지수단으로 구성되어 있다.In order to achieve the object described above, the present invention, in the structure for mounting the sub-circuit board to one side wall portion of the heat sink surrounding the flyback transformer mounted on the main circuit board of the monitor, inclined downward on both sides A body part having a protruding support plate, a fixing means formed to fix the subcircuit board on the upper part of the body part, and a lower part of the body part so that the body part and the subcircuit board are supported on one side wall of the heat dissipation member. It consists of formed support means.

따라서, 상기한 기술 구성에 의해, 작업자는 부회로기판을 상기 방열 부재의 측면에 고정하고자 할 때, 상기한 고정 수단과 지지 수단에 의해 부회로기판을 방열 부재의 일측벽부에 고정하면 되는 것이다.Therefore, according to the above technical configuration, when the operator wants to fix the subcircuit board to the side of the heat dissipation member, the operator may fix the subcircuit board to one side wall of the heat dissipation member by the fixing means and the support means. .

이하, 본 고안에 따른 회로기판 고정기의 일 실시예를 첨부된 예시도면을 참조로 하여 상세하게 설명한다.Hereinafter, an embodiment of a circuit board holder according to the present invention will be described in detail with reference to the accompanying drawings.

제1도에 도시된 바와 같이, 본 고안에 따른 모니터의 회로기판 고정기는, 양측부에 아래로 경사지게 돌출된 받침판(50a)이 형성된 몸체부(50)와, 상기 몸체부(50)의 상부에 부회로기판(5a)을 고정하기 위해 형성된 고정 수단(54), 그리고, 상기 몸체부(50)와 상기 부회로기판(52)이 방열부재(56)의 일측벽부에 지지되도록 상기 몸체부(50)의 하부에 형성된 지지 수단(58)으로 구성되어 있다.As shown in FIG. 1, the circuit board holder of the monitor according to the present invention includes a body part 50 having a support plate 50a protruding obliquely downward on both sides thereof, and an upper portion of the body part 50. Fixing means 54 formed to fix the subcircuit board 5a, and the body part 50 such that the body part 50 and the subcircuit board 52 are supported on one side wall of the heat dissipation member 56. The support means 58 formed in the lower part of 50 is comprised.

여기에서, 상기 고정 수단(54)은 부회로기판(52)의 네 모서리 부분에 각각 형성된 고정 구멍 중에 양 모서리 부분의 고정 구멍(52a)에 끼워지도록 상단의 일측부에 형성된 홈(60a)에 의해 형성된 신축 자재한 걸림턱이 구비된 걸림부(60)와 이 걸림부(60)에 연결되어 있고 상기 부회로기판(52)의 바닥면을 받쳐 주는 지지대(62)로 이루어져 있다.Here, the fixing means 54 is formed by grooves 60a formed at one side of the upper end to be fitted into the fixing holes 52a at both corners of the fixing holes respectively formed at the four corner portions of the subcircuit board 52. It consists of a locking portion 60 is provided with a stretchable locking jaw formed and a support 62 connected to the locking portion 60 and supporting the bottom surface of the sub-circuit board 52.

그리고, 상기 지지 수단(58)은 상기 방열 부재(56)의 일측벽부에 고정되도록 형성되어 있는 바, 상기 방열 부재(56)의 일측벽부에 형성된 고정용 관통 구멍(56a)에 끼워 넣어지도록 U 자형으로 터진 홈(64a)에 의해 형성된 신축 자재하고 외측면이 경사진 한 쌍의 걸림턱부(64)와, 이 걸림턱부(64)가 상기 관통 구멍(56a)에 끼워 들어갈 때, 용이하게 끼워 넣을 수 있도록 안내 역할을 하고 상기 걸림턱부(64)의 목 부분이 상기 관통 구멍(56a)내에서 회전축이 되어 본 고정기가 좌우 회전되는 것을 방지되게 하며, 상기 관통 구멍(56a)의 양측에 형성된 안내 구멍(56b)에 관통되는 안내 돌기(66)로 구성된다.In addition, the support means 58 is formed to be fixed to one side wall portion of the heat dissipation member 56, so that the support means 58 is inserted into the fixing through hole 56a formed at one side wall portion of the heat dissipation member 56. A pair of stretchable jaw portions 64 formed by the U-shaped grooves 64a and having an inclined outer surface, and when the catching portions 64 are inserted into the through holes 56a, are easily fitted. It serves as a guide so that the neck portion of the locking jaw portion 64 is a rotation axis in the through hole (56a) to prevent the fixture from being rotated left and right, guides formed on both sides of the through hole (56a) It consists of a guide projection 66 penetrating the hole 56b.

제2도에는 본 고안에 따른 고정기에 의해 부회로기판(52)이 방열부재(56)에 장착되어 있는 상태가 도시되어 있는 바, 상기 걸림턱부(64)는 상기 관통 구멍(56a)에 끼워질 때, 상기 관통 구멍(56a)의 내주면 양측에 닿는 순간, 오무라지기 시작하여 상기 관통 구멍(56a)에 완전히 끼워 넣어지면, 다시 벌어져 본 고정기가 상기 방열 부재(56)로부터 이탈되지 않도록 한다.2 shows a state in which the sub-circuit board 52 is mounted to the heat dissipation member 56 by the fixing device according to the present invention, and the locking jaw portion 64 is fitted into the through hole 56a. At this time, when the inner circumferential surface of the through hole 56a reaches both sides, when it starts to chamfer and is completely inserted into the through hole 56a, the fixing member which is opened again is prevented from being separated from the heat dissipation member 56.

그리고, 상기 받침판(56a)은, 본 고정기가 상기 방열 부재(56)에 장착되었을 때, 상기 방열 부재(56)의 측면과 닿으면서, 탄성을 가지고 양측으로 벌어지게 되어 있는 바, 이는 본 고정기가 상기 걸림턱부(64)의 턱 부분이 상기 방열 부재(56)의 내측면과 닿은 채, 상기 받침판(50a)의 오무라지려는 힘을 받도록 하여, 본 고정기에 의해 상기 부회로기판(52)이 상기 방열 부재(56)에 더욱 견고하게 장착되게 한다.And, when the fixing plate is mounted to the heat dissipation member 56, the support plate 56a is elastically opened to both sides while being in contact with the side surface of the heat dissipation member 56. The sub-circuit board 52 is driven by the fastener so that the jaw portion of the locking jaw portion 64 receives the force to be damaged of the support plate 50a while being in contact with the inner surface of the heat dissipation member 56. The heat dissipation member 56 is more firmly mounted.

이상, 설명한 바와 같이 본 고안에 따른 회로기판의 고정기에 의하면, 작업자가 방열 부재에 상기한 고정기를 매개로 하여 부회로기판을 장착하는 데에 있어서, 비교적 간단한 조립 공정을 통해 편리하게 조립작업을 할 수 있고, 아울러, 관련 조립 부품수도 줄게 되어 생산성 향상을 도모한 데에 우수한 효과가 있다.As described above, according to the fixture of the circuit board according to the present invention, in the worker to mount the sub-circuit board to the heat dissipation member through the above-described fixture, the assembly work can be conveniently performed through a relatively simple assembly process. In addition, the number of related assembly parts can be reduced, which is an excellent effect for improving productivity.
