본 고안은 VCR의 접지구조에 관한 것으로, 보다 상세하게는 접지편이 인쇄회로기판을 경유하지 않고 메인베이스와 하부커버사이에 직접 연결되도록 하므로써 조립이 간편하게 이루어질 수 있도록 하고, 접지효율을 극대화 시킬 수 있도록 한 VCR의 접지구조에 관한 것이다.The present invention relates to the grounding structure of the VCR, and more particularly, the grounding piece is directly connected between the main base and the lower cover without passing through the printed circuit board so that assembly can be made easily and the grounding efficiency can be maximized. It relates to the grounding structure of a VCR.
일반적으로, VCR이나 텔레비젼같은 각종의 전자제품에는 내부에 설치된 인쇄회로기판을 통하여 흐르는 전류중 누설전류가 그 인쇄회로기판상의 부품들에 나쁜 영향을 미치거나 또는 사용자가 취급중 감전되는 현상을 방지하기 위하여 접지구조가 설치된다.In general, in various electronic products such as a VCR or a television, leakage current of a current flowing through a printed circuit board installed therein may adversely affect components on the printed circuit board or prevent a user from electric shock during handling. A grounding structure is installed for this purpose.
이와 같은 VCR에서의 접지구조는 통상 메인인쇄회로기판에 접지편을 설치하여 메인베이스와 하부커버사이에 결합하거나 또는 메인베이스상의 프론트로딩부에 접지편을 설치하여 상부커버와 접지되도록 하고 있는 바, 이와 같은 종래의 VCR에서의 접지구조에서는 상기 메인인쇄회로기판상에 접지편을 설치될 수 있는 구조가 마련되어야 함에 따라 접지편의 금형이 복잡해진다는 문제가 있고, 상기 메인베이스의 프론트로딩부에 접지편을 설치하는 구조에서는 상기 접지편을 프론트로딩부의 상부에 나사로 조이거나 스풋 웰딩을 해야되므로 그 설치작업성이 매우 불량하다는 문제가 있다.In such a VCR, the grounding structure is usually connected to the main cover and the lower cover by installing a grounding piece on the main printed circuit board, or a grounding piece is installed on the front loading part on the main base to be grounded with the upper cover. In such a grounding structure in the conventional VCR, there is a problem that the mold of the grounding piece becomes complicated as the structure for installing the grounding piece on the main printed circuit board must be provided, and the grounding part of the main base is grounded. In the structure of installing the piece, since the ground piece needs to be screwed on the upper portion of the front loading part or the welding is performed, the installation workability is very poor.
본 고안은 이와 같은 종래의 문제점으 해결하기 위한 것으로, 그 목적은 접지편이 인쇄회로기판을 경유하지 않고 메인베이스와 하부커버사이에 직접 연결되도록 하므로써 조립이 간편하게 이루어질 수 있도록 하고, 접지효율을 극대화 시킬 수 있도록 한 새로운 형태의 VCR의 접지구조를 제공하고자 하는 것이다.The present invention is to solve such a conventional problem, the purpose is that the grounding piece is directly connected between the main base and the lower cover without passing through the printed circuit board to facilitate the assembly and maximize the grounding efficiency It is to provide a new type of VCR grounding structure.
이와 같은 목적을 달성하기 위하여, 본 고안은 메인샤시의 일측면 상부로 부터는 상·하면의 중심에 스크류체결홈이 형성된 체결보스가 일정한 높이로 절곡 형성되고, 상기 체결보스의 형성위치에 해당되는 메인베이스의 면상에는 스크류체결공이, 상기 체결보스의 형성위치에 해당되는 하부커버의 면상에는 중심에 스크류관통공이 절곡부가 형성되는 한편, 상기 체결보스의 상면과 하면에는 별도로 마련되는 ㄷ자형의 접지편이 끼워진 상태에서 스크류에 의하여 결합된 특징을 갖는다.In order to achieve the above object, the present invention is formed from the upper part of the upper side of the main chassis, the fastening boss formed with a screw fastening groove formed at the center of the upper and lower sides is bent to a certain height, the main corresponding to the formation position of the fastening boss A screw fastening hole is formed on the surface of the base, and a screw through hole is formed at the center of the lower cover corresponding to the position at which the fastening boss is formed, while a c-shaped ground piece is separately provided on the upper and lower surfaces of the fastening boss. It is characterized by being coupled by screws in the state.
