본 고안은 PCB홀더를 프로젝션TV(Projection) TV, 이하 PTV라 칭함)후방의 백커버(CoverBack)에 고정시키기 위한 PTV용 PCB홀더 고정장치에 관한 것이다.The present invention relates to a PCB holder fixing device for fixing a PCB holder to the back cover (Cover Back) behind the projection TV (Projection TV, hereinafter PTV).
3개의 CRT 및 반사거울등을 이용하여 대형화면을 구성하는 PTV에 있어서, PCB홀더의 길이방향 양단부에 각각 돌출형성된 탄성후크를 백커버의 걸림구멍과 탄성체결한 후 스크류로 고정시키는 방식의 PCB홀더고정장치가 공지되어 있다.In the PTV constituting a large screen using three CRTs and reflective mirrors, a PCB holder in which elastic hooks protruding from both ends of the PCB holder in each longitudinal direction are elastically fastened to the locking holes of the back cover and then fixed by screws. Fixed devices are known.
그러나 이러한 종래의 고정장치는, 탄성을 보장하기 위하여 비교적 얇고 길게 형성될 수 밖에 없는 탄성후크가 백커버의 걸림구멍을 통과하여 외부로 일정길이 돌출하여 있으므로, 운반 또는 수리시 그 돌출부가 파손되기 쉬워 PCB홀더의 고정상태가 해제될 가능성이 높다. 또한 별도의 스크류작업을 필요로 한다.However, such a conventional fixing device has a relatively thin and long elastic hook that protrudes outwardly through the locking hole of the back cover to ensure elasticity, and thus easily protrudes from the protrusion during transportation or repair. There is a high possibility that the PCB holder will be released. It also requires extra screw work.
따라서 본 고안은, 절곡리브등을 이용하여 별도의 스크류 없이도 손쉽게 고정 및 분리가능한 PCB홀더고정장치를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a PCB holder fixing device that can be easily fixed and detached without a separate screw by using a bending rib or the like.
본 고안의 다른 목적은, 전술한 탄성보장과 관계없이 비교적 튼튼하게 제작될 수 있는 절곡리브를 사용하여 외부돌출로 인한 파손가능성을 줄이는 것이다.Another object of the present invention is to reduce the possibility of breakage due to external protrusion by using a bending rib that can be manufactured relatively robust regardless of the aforementioned elastic guarantee.
전술한 목적을 달성하기 위하여 본 고안은 PCB의 일측단부를 수용지지하는 그루브가 수직방향으로 형성된 PCB홀더를 프로젝션 TV후방의 백커버에 고정시키기 위한 PCB홀더고정장치에 있어서, 수직절취부 및 수평절취부가 L자형으로 연속절취된 관통록킹부와 이탈방지용 걸림구멍을 구비한 백커버, 및 상기 관통록킹부의 수직절취부 내로 수용관통되고 수평절취부에 끼움고정되는 절곡리브와, 상기 백커버의 걸림구멍에 탄성적으로 걸림고정되는 탄성후크를 구비한 PCB홀더를 포함하는 것을 특징으로 하는 PCB홀더고정장치를 제공한다.In order to achieve the above object, the present invention provides a PCB holder fixing device for fixing a PCB holder, in which a groove for supporting one end of the PCB is formed in a vertical direction, to a back cover of the rear side of the projection TV, wherein the vertical cutout and the horizontal cutout are provided. A back cover having an additional L-shaped continuous cut through portion and a locking hole for separation, a bent rib that is inserted into the vertical cut portion of the through locking portion and fitted into a horizontal cut portion, and a locking hole of the back cover. It provides a PCB holder fixing device comprising a PCB holder having an elastic hook that is elastically locked to the.
또한 상기 PCB홀더는 상기 절곡리브와 인접하게 설치되어 상기 관통록킹부의 수직절취부를 폐쇄가능한 돌출리브를 더 구비하는 것이 바람직하다. 비교적 긴 PCB홀더를 확고히 고정하기 위하여 상기 백커버의 관통록킹부와 상기 PCB홀더의 절곡리브 및 돌출리브는 각 한쌍씩 마련되어 PCB홀더의 상·하 양단부에 대칭형성되는 것이 유리하다. 또한 상기 탄성후크는 상기 백커버의 걸림구멍에 탄성걸림되어 수평도입반대방향으로의 이탈이 방지되는 걸림턱을 구비하는 것이 좋다.In addition, the PCB holder is preferably provided adjacent to the bent rib further comprises a protrusion rib capable of closing the vertical cut portion of the through-locking portion. In order to firmly fix the relatively long PCB holder, the through-locking portion of the back cover and the bending ribs and the protruding ribs of the PCB holder are provided in pairs, and it is advantageous to be symmetrically formed at both upper and lower ends of the PCB holder. In addition, the elastic hook is preferably provided with a latching jaw that is elastically caught in the engaging hole of the back cover to prevent the departure in the opposite direction to the horizontal introduction.
이하에서 첨부한 도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 PCB홀더고정장치의 분해사시도이며, 제2도는 PCB홀더의 측면도이다. 제1도 및 제2도에 도시된 바와 같이 본 고안에 따른 PCB홀더고정장치는, 관통록킹부(11) 및 걸림구멍(14)이 형성된 백커버(10)와 전술한 관통록킹부(11) 및 걸림구멍(14)과 각각 상호 관계하는 걸곡리브(3) 및 탄성후크(6)가 일체성형된 PCB홀더(1)를 포함한다.1 is an exploded perspective view of a PCB holder fixing device according to the present invention, Figure 2 is a side view of the PCB holder. As shown in FIGS. 1 and 2, the PCB holder fixing device according to the present invention includes a back cover 10 having a through locking portion 11 and a locking hole 14 and the above-described through locking portion 11. And a PCB holder 1 in which the engaging ribs 3 and the elastic hooks 6, which are mutually associated with the engaging holes 14, are integrally formed.
본 실시예에서, 관통록킹부(11)와 절곡리브(3) 및 후술할 돌출리브(4)와 보강리브(5)는 PCB홀더(1)의 상하 단부영역에 각각 대칭형성되어 있으나 그 구조와 기능이 각각 완전 동일하므로 이하의 설명에서는 일일이 반복언급하지 않기로 한다.In the present embodiment, the through-locking portion 11 and the bending ribs 3 and the protruding ribs 4 and the reinforcing ribs 5 to be described later are symmetrically formed in the upper and lower end regions of the PCB holder 1, respectively. Since the functions are completely identical to each other, the following description will not be repeated.
백커버(10)의 관통록킹부(11)는 L자형으로 연속절취된 수직절취부(12)와 수평절취부(13)로 이루어진다. PCB홀더(1)의 전방면에는 통상의 PCB홀더(1)에서 볼수 있듯이 PCB(20)의 일측단부를 수용지지하는 그루브(2)가 수직방향으로 길게 형성되어 있으며, 도시한 바와 같은 형상을 갖는 보강리브(5)가 PCB홀더(1)의 그루브(2)주위를 가로로 감싸서 보강하고 있다.The through-locking portion 11 of the back cover 10 includes a vertical cut portion 12 and a horizontal cut portion 13 continuously cut in an L shape. On the front surface of the PCB holder 1, as shown in the conventional PCB holder 1, a groove 2 for receiving one end of the PCB 20 is formed long in the vertical direction, and has a shape as shown. A reinforcing rib 5 wraps around the groove 2 of the PCB holder 1 and reinforces it horizontally.
절곡리브(3)는 PCB홀더(1)의 상·하 단부영역에서 백커버(10)방향으로 적정길이, 바람직하게는 백커버(10)의 두께만큼, 돌출연장된 연장부(3')와 연장부(3')에서 수직상방향으로 절곡된 절곡부(3")로 이루어진다. 이때 절곡부(3")의 판면크기는 전술한 수직절취부(12)를 통과가능하도록 제한되며, 연장부(3')의 상·하 폭도 수평절취부(13)의 상·하폭과 거의 일치하여 끼움 고정될수 있도록 제한된다. 또한 PCB홀더(1)에는 절곡리브(3)가 전술한 수직절취부(12)를 통과하여 수평절취부(13)방향으로 이이동하면 수직절취부(12)가 개방상태로 되어 이를 통해 외부 이물질등이 전자기기내로 들어오기 쉬우므로, 수직절취부(12)를 폐쇄가능한 돌출리브(4)가 절곡리브(3)에서 적절히 이격설치되어 있다.The bending ribs 3 extend from the upper and lower end regions of the PCB holder 1 by the appropriate length in the direction of the back cover 10, preferably by the thickness of the back cover 10, with the extension part 3 'protrudingly extended. It consists of a bent portion 3 "bent vertically in the extension portion 3 '. At this time, the plate size of the bent portion 3" is limited to pass through the above-described vertical cutout portion 12, and the extension portion The upper and lower widths of 3 'are also limited so that the upper and lower widths of the 3' can be fixed in almost the same as the upper and lower widths of the horizontal cutout portion 13. In addition, when the bending rib 3 moves in the horizontal cutout 13 direction in the PCB holder 1 through the aforementioned vertical cutout 12, the vertical cutout 12 is opened and foreign foreign matters are opened. Since the back and the like easily enter the electronic device, the protruding ribs 4 capable of closing the vertical cutout portions 12 are appropriately spaced apart from the bent ribs 3.
한편, PCB홀더(1)의 절곡리브(3)가 백커버(10)의 수평절취부(13)내로 수평도입됨과 동시에 백커버(10)의 걸림구멍(14)에 걸림고정되도록 설치되는 탄성후크(6)는, 경사부(6') 및 걸림턱(6")을 구비하여 PCB홀더(1)의 길이방향 중간부에서 백커버(10)의 판면에 평행하게 돌출형성되어 있다.Meanwhile, an elastic hook is installed such that the bending rib 3 of the PCB holder 1 is horizontally introduced into the horizontal cutout portion 13 of the back cover 10 and at the same time is fixed to the locking hole 14 of the back cover 10. 6 is provided with an inclined part 6 'and a latching jaw 6 ", and protrudes in parallel with the plate surface of the back cover 10 in the longitudinal middle part of the PCB holder 1. As shown in FIG.
제3도는 상기와 같은 구성을 갖는 본 고정장치의 조립평면도로서 제3(a)도는 고정전 밀착상태를, 제3(b)도도는 고정상태를 도시한 것이다. 제2(a)도에서 볼 수 있는 바와 같이, PCB홀더(1)를 백커버(10)에 고정시키려면 먼저, 수직절취부(12)를 통과한 절곡리브(3)의 절곡부(3")가 백커버(10)의 외부로 돌출된 상태에서 절곡리브(3)의 연장부(3')(3")가 수평절취부(13)에 끼움고정되도록 PCB홀더(1)를 적절히 수평이동시킨다. 이 수평이동에 의햐여 PCB홀더(1)에 일채성형된 탄성후크(6)로 휘어진 상태로 백커버(10)의 걸림구멍(14)쪽으로 이동되며 최종적으로 걸림턱(6")이 걸림구멍(14)내에 삽입고정된다.FIG. 3 is an assembly plan view of the present fixing device having the above configuration, and FIG. 3 (a) shows a close contact state before fixation and FIG. 3 (b) shows a fixed state. As can be seen in FIG. 2 (a), to fix the PCB holder 1 to the back cover 10, first, the bent portion 3 " of the bent rib 3 passing through the vertical cutout portion 12 " ), The PCB holder 1 is properly horizontally moved so that the extension portions 3 'and 3 "of the bending ribs 3 are fitted into the horizontal cutouts 13 with the protrusion protruded out of the back cover 10. Let's do it. By this horizontal movement, it is moved toward the engaging hole 14 of the back cover 10 in a state of being bent by the elastic hook 6 molded into the PCB holder 1, and finally the engaging jaw 6 "is engaged with the engaging hole ( 14) Inserted and fixed
따라서, 수평절취부(13)와 절곡리브(3)의 상호작용에 의하여 백커버(10)에 대한 PCB홀더(1)의 전후방향 및 수직방향이동이 방지되며, 걸림구멍(14)과 탄성후크(6)의 상호작용에 의하여 백커버(10)에 대한 PCB홀더(1)의 수평도입반대방향으로의 이탈이 방지됨으로써 PCB홀더(1)가 백커버(10)에 확고히 고정된다.Therefore, the front and back and vertical movement of the PCB holder 1 with respect to the back cover 10 is prevented by the interaction between the horizontal cutout portion 13 and the bending rib 3, and the locking hole 14 and the elastic hook The PCB holder 1 is firmly fixed to the back cover 10 by the separation of the PCB holder 1 against the back cover 10 in the opposite direction of horizontal introduction by the interaction of (6).
본 고정장치에서는 탄성후크(6)가 걸림구멍(14)내에 완저히 수용되어 백커버(10)의 후방으로 돌출하지 않는다. 또한 절곡리브(3)의 절곡부(3")가 백커버(10)의 후방표면에서 돌출하여 있으나, 서두에서 언급한 종래 고정장치의 한계(탄성보장)와는 무관하므로 충분한 내충격성을 갖는 두께로 연장부(3') 및 절국부(3")를 형성할 수 있다. 필요에 따라서는, 돌출한 절곡부(3")의 각 모서리를 둥글게 혹은 경사지게 처리하여 더욱 효과적으로 외부충격에 대응케할 수 있다.In this fixing device, the elastic hook 6 is completely received in the locking hole 14 and does not protrude rearward of the back cover 10. In addition, although the bent portion 3 ″ of the bent rib 3 protrudes from the rear surface of the back cover 10, it has a thickness that has sufficient impact resistance because it is not related to the limitation (elastic guarantee) of the conventional fixing device mentioned at the outset. Extensions 3 'and cutouts 3 "may be formed. If necessary, the corners of the protruding bent portion 3 ″ may be rounded or inclined to more effectively respond to external shocks.
한편, PCB홀더(1)를 백커버(10)로부터 분리하고자 할 경우에는 , 탄성후크(6)의 걸림턱(6")을 걸림구멍(14)의 대응연부에서 벗어나도록 백커버(10)의 후방으로부터 밀어줌과 동시에, 절곡리브(3)를 도입반대방향으로 수평이동시켜 수평절취부(13)로부터 벗어나게 한 후 수직절취부(12)를 통하여 전방으로 빼내면 된다.On the other hand, when the PCB holder 1 is to be separated from the back cover 10, the locking jaw 6 ″ of the elastic hook 6 is deviated from the corresponding edge of the locking hole 14 of the back cover 10. Simultaneously pushing from the rear, the bending ribs 3 are horizontally moved in the opposite direction of introduction to move away from the horizontal cutout 13 and then pulled forward through the vertical cutout 12.
이상 설명한 바와 같이 본 고안은, 별도의 스크류 없이도 손쉽게 고정 및 분리가능하며 충분한 내충격성을 지닌 PTV용 PCB홀더 고정장치를 제공한다.As described above, the present invention provides a PCB holder fixing device for a PTV that can be easily fixed and detached without a separate screw and has sufficient impact resistance.
