본 고안은 튜너샤시에 관한 것으로, 특히 샤시의 측면판 내측에 지지돌기가 형성되어져 쉴드플레이트가 용이하게 고정될 수 있게 됨은 물론 샤시의 금형이 간단해지도록 된 튜너샤시에 관한 것이다.The present invention relates to a tuner chassis, and more particularly, to a tuner chassis in which a support protrusion is formed inside the side plate of the chassis so that the shield plate can be easily fixed, as well as the mold of the chassis is simplified.
일반적으로 텔레비젼 튜너의 샤시에는 국부발진기에서의 주파수방사를 막고 외부잡음에 의한 각 구획간의 불리한 영향을 방지해주기 위해 쉴드플레이트(shied plate)를 설치해 놓고 있는 바, 이 쉴드플레이트는 샤시의 측면판과 함께 일체로 된 상태에서 프레스공정에 의해 필요한 형태로 제작되어 절곡공정에 의해 조립되도록 되어 있다.In general, a chassis of a TV tuner is provided with a shielded plate to prevent frequency radiation from the local oscillator and to prevent adverse effects between the compartments due to external noise. The shield plate is provided with the side plate of the chassis. It is manufactured in the form required by the pressing process in an integrated state and is assembled by the bending process.
한편, 종래의 튜너샤시는 제1도에서 보여주고 있듯이 쉴드플레이트(5)의 지지돌기(3)가 샤시특면판(2)의 변부로 부터 절단되어 형성된 다음 측면판(2)의 구멍(9)에 끼워지도록 되어 있는바, 이는 샤시의 두께가 0.6㎝정도로 얇기 때문에 상기 지지돌기(3)가 끼워지게 되는 구멍(9)의 크기 또한 그 폭을 0.08㎝ 이하로 형성시켜주게 됨으로써 펀치가 부러지게 되는 등 펀칭공정에 어려움이 있을 뿐만 아니라, 상기 지지돌기(3)의 형성에 따른 절단홈(10)이 생성됨으로 말이암아 샤시커버를 고정시켜주기 위한 걸림턱(7)을 충분한 길이로 형성시켜 줄 수 없어 커버가 제대로 조립되지 않거나 떨림현상이 발생하게 되고, 또 상기 지지돌기(3)와 절단홈(10)의 형상에 따른 프레스금형이 복잡해져 제작비가 상승되게되는 등 문제점이 있었다.Meanwhile, as shown in FIG. 1, the conventional tuner chassis is formed by cutting the support protrusion 3 of the shield plate 5 from the edge of the chassis face plate 2, and then opening the hole 9 of the side plate 2. The thickness of the chassis 9 is about 0.6 cm, so that the size of the hole 9 into which the support protrusion 3 is inserted is also formed to a width of 0.08 cm or less, thereby causing the punch to break. In addition to the difficulty in the punching process, such that the cutting groove 10 is formed in accordance with the formation of the support projection (3) can be formed to a sufficient length of the latching jaw (7) for fixing the chassis cover. There is a problem such that the cover is not properly assembled or the shaking phenomenon occurs, and the press mold according to the shape of the support protrusion 3 and the cutting groove 10 is complicated to increase the production cost.
이에 본 고안은 상기와 같은 문제점을 해결해주기 위하여 안출된 것으로, 샤시측면판 안쪽으로 지지돌기를 형성시켜 쉴드플레이트의 측변을 고정시켜줌으로써, 샤시의 금형이 간단해지게 되면서 샤시커버의 지지력도 보강되도록 된 튜너샤시를 제공하는 데 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and by forming a support protrusion inside the chassis side plate to fix the side of the shield plate, the mold of the chassis is simplified and the support force of the chassis cover is also reinforced. The purpose is to provide a tuner chassis.
이하 본 고안의 구성 및 작용, 효과를 예시된 도면에 의거 상세히 설명한다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the illustrated drawings.
본 고안은 샤시(1)의 측면판(2) 내측에 다수의 지지돌기(3)가 형성되면서, 상기 지지돌기(3) 사이에는 결합홈(4)이 형성되며, 상기 결합홈(4)에는 쉴드플레이트(5)의 측변부(6)가 결압되는 구조로 되어 있다.According to the present invention, a plurality of support protrusions 3 are formed inside the side plate 2 of the chassis 1, and a coupling groove 4 is formed between the support protrusions 3 and the coupling groove 4. The side portion 6 of the shield plate 5 is structured to be pressed.
미 설명 부호 7은 걸림턱, 8은 고정돌기이다.Reference numeral 7 is a locking jaw, 8 is a fixing projection.
상기와 같은 구조로 된 본 고안은 지지돌기(3) 사이의 결합홈(4)에 쉴드플레이트(5)의 측변부(6)가 끼워져 고정되게 됨으로써 상기 쉴드플레이트(5)의 측변부(6)와 샤시측면판(2) 가장자리의 금형이 간단해지게 되어 있다.The present invention having the structure as described above is the side portion 6 of the shield plate (5) is fitted into the coupling groove (4) between the support projections (3) by the side portion (6) of the shield plate (5) The mold at the edge of the chassis side plate 2 is simplified.
한편, 제2도는 본 고안의 일부결합상태도로서, 샤시 측면판(2)의 결합홈(4)에 쉴드플레이트(5)의 측변부(6)가 결합되어 있는 것을 보여주고 있는데, 그 결합상태를 살펴보면, 쉴드플레이트(5)가 형성되어 있고, 측면판(2)에 지지돌기(3)와 함께 걸림턱(7)이 형성되어 있는 상태의 샤시(1)로부터 쉴드플레이트(5)를 밑으로 절곡시키고, 샤시측면판(2)을 상기 쉴드플레이트(5)의 측변부(6)쪽으로 절곡시키세 되면 이 측변부(6)가 상기 측면판(2)안쪽으로 형성되어 있는 지지돌기(3) 사이의 결합홈(4)에 결합되게 되고, 이어 상기 측면판(2)의 고정돌기(8)를 코킹시켜줌으로써 완전히 결합되게 된다.On the other hand, Figure 2 is a part of the coupling state of the present invention, showing that the side portion 6 of the shield plate 5 is coupled to the coupling groove 4 of the chassis side plate 2, the coupling state Looking at it, the shield plate (5) is formed, bending the shield plate (5) downward from the chassis (1) with the support projection (3) and the locking projection (7) is formed on the side plate (2) When the chassis side plate (2) is bent toward the side portion (6) of the shield plate (5), the side portions (6) between the support protrusions (3) formed inside the side plate (2) It is to be coupled to the coupling groove (4), and then to be completely coupled by caulking the fixing projections (8) of the side plate (2).
이때 상기 지지돌기(3)는 제3도에 도시된 바와 같이 엠보싱(embossing) 공정에 의해 형성되면서 2개가 근접 위치되어 결합홈(4)이 형성되어져 양쪽에서 쉴드플레이트(5)의 측변부(6)를 지지시켜준다. 한편 이와같이 쉴드플레이트(5)의 측변부가 직접 결합홈(6)에 결합됨으로써 종래에 쉴드플레이트(5)의 지지돌기(3)를 형성시킬 때 형성되는 측면판(2)의 절단홈(10)이 제거되어 커버(도시되어 있지 않음)가 걸리게 되는 걸림턱(7)을 길이방향으로 더욱 연장시킬 수가 있다.At this time, the supporting protrusions 3 are formed by an embossing process as shown in FIG. 3, and two of the supporting protrusions 3 are located close to each other so that the coupling grooves 4 are formed on both sides of the shield plate 5. ). Meanwhile, the side grooves of the shield plate 5 are directly coupled to the coupling grooves 6 so that the cutting grooves 10 of the side plates 2 formed when conventionally forming the supporting protrusions 3 of the shield plate 5 are formed. It is possible to further extend the latching jaw 7 in which the cover (not shown) is removed to extend in the longitudinal direction.
상기와 같은 구성과 작용에 의하여 본 고안은 금형을 간단히 해줌으로서 생산성이 향상되고, 제작비를 절감시킬 수 있을 뿐만 아니라, 걸림턱(7)의 길이가 연장됨으로써 커버의 결합력을 높이게 되어 제품을 향상시키는 효과가 있다.By the construction and operation as described above, the present invention improves the product by simplifying the mold, thereby improving productivity, reducing manufacturing costs, and increasing the engagement force of the cover by extending the length of the locking jaw (7). It works.
