본 고안의 위성방송 수신 컨버터(LNB)에 관한 것으로서, 더욱 상세하게는 컨버터의 메인 기판을 동작시키기 위해 메인 기판상에 씌워지는 실딩구조에 관한 것이다.The present invention relates to a satellite broadcasting receiver (LNB) of the present invention, and more particularly, to a shielding structure that is covered on a main substrate for operating the main substrate of the converter.

일반적으로 위성방송 수신 시스템은 정지위성으로부터 발사된 전자파를 접속하는 접속부와, 상기 접속부의 촛점에 설치되어 접속된 전자파를 수신하고 케이블을 통해 TV 수상기로 전달하는 수신 컨버터로 구성된 것으로서, 상기 수신 컨버터내에는 정지 위성에서 발사된 약 11~12GHz의 주파수를 약 1GHz로 다운시키기 위한 회로 및 부품이 설치되어 있다.In general, a satellite broadcasting receiving system includes a connection unit for connecting electromagnetic waves emitted from a stationary satellite, and a reception converter installed at a focus of the connection unit to receive and transmit the connected electromagnetic waves to a TV receiver through a cable. Is equipped with circuits and components to reduce the frequency of about 11-12 GHz from stationary satellites to about 1 GHz.

이러한 수신 컨버터는 제1도에 도시된 바와 같이, 알루미늄 다이캐스팅으로 제조되는 베이스(1)상에 통상 저잡음증폭, 믹싱, 국부발진기, IF증폭을 하는 메인 기판(2)과 상기 메인 기판(2)의 저잡음 증폭기, 믹서, 국부발진기에 전원을 공급해 주는 파워 기판(3)으로 구성된다.Such a receive converter is shown in FIG. 1 of the main substrate 2 and the main substrate 2 which typically perform low noise amplification, mixing, local oscillator, IF amplification on the base 1 made of aluminum die casting. It consists of a power board 3 which supplies power to a low noise amplifier, a mixer and a local oscillator.

상기와 같은 수신 컨버터의 메인기판(2)이 적절히 동작하기 위해서는 금속 실딩(Shielding)이 필요하다. 종래의 실딩구조는 제1도에서와 같이, 알루미늄 다이 캐스팅으로 제조한 금속 캐비티(4)를 메인 기판(2)상에 씌워 실딩하였다.In order for the main substrate 2 of the receiving converter as described above to operate properly, metal shielding is required. In the conventional shielding structure, as shown in FIG. 1, the metal cavity 4 made of aluminum die casting was covered on the main substrate 2 and shielded.

그러나 상기와 같은 실딩구조는 캐비티(4)를 알루미늄 다이캐스팅으로 제조하기 때문에 제작비가 상승하는 문제점이 있다. 좀더 개량된 것으로, 일부에서는 상기 캐비티(4)를 주석판을 절곡하여 형성한 것도 있으나 이도 역시 제작이 번거롭고 고가인 단점이 있었다.However, the above shielding structure has a problem in that the manufacturing cost increases because the cavity 4 is manufactured by aluminum die casting. As a further improvement, some of the cavity 4 is formed by bending the tin plate, but this also has the disadvantage of being cumbersome and expensive.

본 고안은 상기와 같은 종래의 문제점을 감안하여 해결하기 위한 것으로서, 그 목적은 수신 컨버터의 메인 기판상에 씌워지는 실딩작업이 간단하게 이루어질 수 있는 위성방송 수신컨버터의 실딩구조를 제공하는데 있다.The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a shielding structure of a satellite broadcasting receiver converter which can be easily covered on a main substrate of a receiver converter.

본 고안의 다른 목적은 상기 실딩구조의 당가를 종래의 알루미늄 다이캐스팅이나 함석판에 의한 구조보다 현저하게 낮출 수 있는 위성방송 수신 컨버터의 실딩 구조를 제공하는데 있다.Another object of the present invention is to provide a shielding structure of a satellite broadcasting receiver which can significantly lower the sugar value of the shielding structure than that of a conventional aluminum die casting or tin plate structure.

상기와 같은 목적은 베이스상에 구성되어 저잡음 증폭믹싱, 국부발진, IF 증폭을 행하는 메인기판과, 상기 메인 기판에 전원을 공급하는 파워 기판으로 이루어진 위성방송 수신 컨버터의 실딩구조에 있어서, 상기 메인 기판이 설치되는 베이스상에 테두리부를 돌출성형하고 동박 테이프의 접착부를 상기 테두리부의 바깥측에 부착하는 위성방송 수신 컨버터의 실딩구조에 의해 달성될 수 있다.In the shielding structure of the satellite broadcasting receiver converter comprising a main board configured on a base to perform low noise amplification mixing, local oscillation, and IF amplification, and a power board for supplying power to the main board. It can be achieved by the shielding structure of the satellite broadcasting receiver which protrudes the edge portion on the base to be installed and attaches the adhesive portion of the copper foil tape to the outside of the edge portion.

이하, 본 고안에 따른 위성방송 수신 컨버터의 실딩구조를 첨부도면에 의하여 상세하게 설명한다.Hereinafter, the shielding structure of the satellite broadcasting receiver according to the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 고안의 수신 컨버터 실딩 구조를 나타낸 분리사시도로써, 알루미늄 다이캐스팅으로 제조되는 베이스(10)상에 저잡음 증폭, 믹싱, 국부발진, IF 증폭을 행하는 메인기판(11)이 설치되고, 상기 베이스(10)의 하부에는 상기 메인기판(11)으로 전원을 공급하는 파워기판(12)이 설치된 구성이다.2 is an exploded perspective view showing the receiving converter shielding structure of the present invention, wherein a main substrate 11 for low noise amplification, mixing, local oscillation, and IF amplification is installed on a base 10 made of aluminum die casting. The lower part of the (10) is a configuration in which a power substrate 12 for supplying power to the main substrate (11) is installed.

또한, 상기 메인기판(11)에는 메인기판(11)의 적절한 동작을 위해 금속 실딩이 이루어져야 하고, 본 고안에서는 금속실딩이 동박을 코팅한 동박 테이프(13)로 이루어진다.In addition, the main substrate 11 should be made of metal shielding for proper operation of the main substrate 11, in the present invention, the metal shielding is made of a copper foil tape 13 coated with copper foil.

즉, 베이스(10)상에 테두리부(10a)를 돌출성형하고, 테두리 바깥측으로 동박 테이프(13)의 접착부(13a)를 부착함으로써 캐비티가 형성된다.That is, a cavity is formed by protruding the edge portion 10a on the base 10 and attaching the adhesive portion 13a of the copper foil tape 13 to the outside of the edge portion.

이와 같은 구성의 본 고안은 수신 컨버터의 실딩을 위한 캐비티가 동박을 코팅한 동박 테이프(13)로 이루어지기 때문에 재료비가 낮아 코스트를 다운시킬 수 있는 것이고, 또한 상기 동박 테이프(13)로 구성한 캐비티를 베이스(10)에 조립할 경우 베이스(10)의 테두리부(10a)에 동박 테이프(13)의 접착력으로 동박 테이프(13)의 접착부(13a)를 붙이면 조립이 간단하게 이루어지기 때문에 조립능률이 향상된다.According to the present invention, the cavity for shielding the receiving converter is made of copper foil coated copper foil 13 so that the cost of materials can be lowered and the cavity composed of the copper foil tape 13 can be reduced. When assembling to the base 10, assembling is simplified by attaching the adhesive portion 13a of the copper foil tape 13 to the edge portion 10a of the base 10 with the adhesive force of the copper foil tape 13, thereby improving the assembly efficiency. .

이상에서와 같이 본 고안에 따른 위성방송 수신 컨버터의 실딩구조에 의하면, 수신 컨버터의 실딩을 위한 캐비티가 동박 테이프로 구성되어 단가를 낮출 수 있게 되고,상기 동작 테이프를 베이스의 양측면에 부착시키어 조립되므로 조립능률이 향상되는 효과가 있다.According to the shielding structure of the satellite broadcasting receiver according to the present invention as described above, the cavity for the shielding of the receiver converter is composed of copper foil tape can be lowered the unit cost, and is assembled by attaching the operation tape to both sides of the base The assembly efficiency is improved.
