본 고안은 CRT 모니터 또는 컴퓨터 등의 산업기기 및 일반가전제품 등에 사용되는 PCB 받침용 샤시의 결합구조에 관한 것으로 특히 기기의 캐비닛에 PCB 받침용샤시를 결합하는 경우에 스크류우나 고정편 등의 별도의 부품없이도 간단하고 견고하게 결합할 수 있도록 하기 위한 것이다.The present invention relates to a coupling structure of a PCB support chassis used for industrial equipment such as a CRT monitor or a computer, and general home appliances. In particular, when the PCB support chassis is coupled to a cabinet of a device, a screw or a fixing piece, etc. It is intended to allow simple and solid mating without parts.

종래의 경우 CRT모니터의 프론트캐비닛과 백 캐비닛에 PCB 받침용샤시를 결합할 때 스크류 등 별도의 복잡한 구조물을 사용하기 때문에 작업공수가 증가하여 조립이 복잡하고 이에 따라 생산성이 저하 된다는 문제점이 제기되었다.In the conventional case, when the PCB support chassis is coupled to the front cabinet and the back cabinet of the CRT monitor, a separate complicated structure such as a screw is used, which increases the labor time and raises the complexity of the assembly.

본 고안은 이러한 문제점을 해결하기 위한 것으로 CRT 모니터의 프론트 캐비닛 및 백 캐비닛의 일정위치에 PCB 받침용 샤시를 안내하여 결합시키는 기능을 갖는 고정부재를 형성하고 상기 PCB 받침용샤시의 좌우측면에는 고정부재에 형합고정되는 가이드레일과 결합공으로 이루어지는 안내부재를 형성함으로써 별도의 부품을 사용하지 않고도 PCB 받침용샤시를 정확하고 간편하게 결합할 수 있도록 하고자 하는데 목적이 있다. 첨부된 도면에 의하여 본 고안의 실시예를 상세히 설명하면 다음과 같다.The present invention is to solve this problem to form a fixing member having a function of guiding and coupling the PCB support chassis at a predetermined position of the front cabinet and back cabinet of the CRT monitor and the fixing member on the left and right sides of the PCB support chassis. The purpose is to form a guide member consisting of a guide rail and a coupling hole to be fixed to the PCB to accurately and easily combine the PCB support chassis without using a separate component. Referring to the embodiments of the present invention in detail by the accompanying drawings as follows.

본 고안은 제 1 도에 도시된 바와같이 CRT 모니터의 프론트 캐비닛(1)의 하단 일정지점과 백캐비닛(4) 일정지점에 형성한 고정부재 및 PCB 받침용샤시(3)의 좌우측면에 형성한 수개의 가이드레일(3a)과 결합공(3b)으로 이루어지는 안내부재로 구성되는데 상기 고정 부재는 PCB받침용샤시(3)에 형성된 가이드레일(3a)을 안내하여 결합시키는 기능을 하는 것으로 프론트캐비닛(1) 내측의 하단부 좌우측에 끝단부가 바깥쪽으로 절곡된 탄성의 샤시착탈손잡이(2)를 각각 돌설하고 상기한 샤시착탈손잡이와 일체로 된 가이드리브 "A"(2a)를 절곡방향과 반대방향으로 돌설하는 한편 샤시착탈손잡이면의 중심선상의 일정지점에는 PCB 받침용샤시(3)가 상기 가이드리브"A"(2a)에 안내되어 결합된 후 유동되는 것을 방지하기 위한 걸림턱(2b)이 돌출된 구조로 이루어지며 백캐비닛(4)의 하단 일정지점 좌우측에는 PCB 받침용샤시(3)에 형성된 가이드레일(3a)에 끼워져 상호 체결되도록 하는 가이드리브"B"(4a)가 돌설된 구조로 이루어진다.The present invention, as shown in Figure 1 formed on the left and right sides of the fixing member and the PCB support chassis 3 formed at a predetermined point of the lower end of the front cabinet 1 of the CRT monitor and a certain point of the back cabinet (4) It consists of a guide member consisting of several guide rails (3a) and coupling holes (3b), the fixing member is to guide and combine the guide rail (3a) formed in the PCB support chassis (3) front cabinet ( 1) Each of the elastic chassis attachment and detachment handles 2 whose ends are bent outwardly on the left and right sides of the inner lower end portion, respectively, and the guide rib " A " On the other hand, at a certain point on the center line of the chassis attachment / detachment back and forth, the latching base 2b for preventing the PCB support chassis 3 from being guided and coupled to the guide rib " A " Structured back caviar The left and right sides of the lower portion of the garnet 4 is made of a structure in which the guide ribs "B" (4a) are inserted into the guide rail (3a) formed on the PCB support chassis (3) to be fastened to each other.

한편 PCB 받침용샤시(3)의 좌우측면에 돌설되는 가이드레일(3a)은 프론트캐비닛(1)에 형성된 가이드리브"A"(2a)와 백캐비닛(4)의 가이드리브"B"(4a)에 결합되어 프론트캐비닛 및 백캐비닛을 상호 체결하는 기능을 갖는 것으로 각 측면에 3쌍이 돌설되고 가이드리브 "A"(2a)에 안내되는 가이드레일(3a)의 뒷쪽에는 결합공(3b)이 형성되는데 이때 각각의 가이드레일 사이의 간격을 샤시착탈손잡이(2) 상의 걸림턱(2b)이나 백캐비닛에 돌설된 가이드리브"B"(4a)의 두께보다 약간 더 넓게 구성하여 상기 걸림턱이나 가이드리브 "B"가 각 가이드레일 사이를 통과할 수 있도록한 구조로 이루어진다.Meanwhile, the guide rails 3a protruding from the left and right sides of the PCB support chassis 3 are guide ribs “A” (2a) formed on the front cabinet 1 and guide ribs “B” (4a) of the back cabinet 4. It is coupled to the front cabinet and the back cabinet to have a function of mutual coupling three pairs on each side and the guide rail (3a) guided to the guide rib "A" (2a) is formed in the coupling hole (3b) At this time, the spacing between the guide rails is configured to be slightly wider than the thickness of the locking jaw (2b) or the guide ribs "B" (4a) protruding in the back cabinet on the chassis attachment and detachment handle (2). It is made of a structure that allows B "to pass between each guide rail.

이와같은 구성을 갖는 본 고안의 작용은 PCB 받침용 샤시(3)를 결합하는 경우와 해체하는 경우로 나누어 설명할 수 있는바 먼저 PCB 받침용샤시(3)를 결합하는 경우에는 제 2a 도에 도시된 바와같이 PCB 받침용 샤시에 형성된 가이드레일(3a)을 프론트캐비닛(1)의 샤시착탈손잡이(2)에 돌설된 가이드리브 "A"(2a)에 형합시켜 슬라이드시키면 걸림턱(2b)이 가이드레일의 중심을 통과하여 제 2b 도에 도시된 바와같이 결합공(3b)에 삽입되어 걸리면서 프론트캐비닛(1)과의 결합이 이루어지면서 이상태에서 PCB 받침용샤시(3) 좌우측면의 뒤쪽에 돌설된 가이드레일(3a)을 제 3 도에 도시된 바와같이 가이드리브 "B"(4a)에 슬라이드시키면서 끼워 맞추면 백캐비닛(4)과의 체결이 이루어진다.The operation of the present invention having such a configuration can be divided into the case of combining and dismantling the PCB support chassis (3) bar first when combining the PCB support chassis (3) is shown in Figure 2a As shown in the drawing, the guide rails 3a formed on the PCB support chassis are combined with the guide ribs " A " 2a protruding from the chassis attachment and detachment handles 2 of the front cabinet 1, and the locking jaws 2b are guided. Passed through the center of the rail is inserted into the coupling hole (3b) as shown in Fig. 2b and engaged with the front cabinet (1) while protruding to the rear of the left and right sides of the PCB support chassis (3) in this state When the guide rails 3a are fitted while sliding to the guide ribs " B " 4a as shown in Fig. 3, the guide rails 3a are fastened to the back cabinet 4.

한편 결합상태로 부터 PCB 받침용 샤시(3)를 해체하고자 할 경우에는 결합시와는 역순으로 백캐비닛(4)을 PCB받침용샤시와 분리한 후 프론트캐비닛(1)에 돌설된 샤시 착탈손잡이(2)를 바깥쪽으로 밀면 샤시착탈손잡이가 탄성에 의하여 힘의작용 방향으로 밀리면서 결합공(3b)에 삽입되어 있던 걸림턱(2b)이 이탈되어 결합상태가 해체된다.On the other hand, if you want to disassemble the PCB support chassis (3) from the combined state, separate the back cabinet (4) from the PCB support chassis in the reverse order of the combination, then the chassis detachable handles protruding from the front cabinet (1) When 2) is pushed outward, the locking jaw (2b) inserted into the coupling hole (3b) is removed while the chassis attachment / detachment knob is pushed in the direction of the force of action by the elasticity to dismantle the coupling state.

이와같은 작용을 갖는 본 고안의 효과로는 PCB 받침용 샤시의 결합시 스크류우나 고정편등과 같은 별도의 부품을 사용하지 않으므로 작업이 간편해지고 이에 따라 작업공수가 줄어들어 결과적으로 생산성이 형상된다는 이점이 있다.The effect of the present invention having such a function is that when the PCB support chassis is combined, it does not use a separate component such as a screw or a fixing piece, thus simplifying the work and thus reducing the labor time, resulting in the productivity. have.
