본 고안은 비디오 테이프 레코오더(VTR)의 드럼 어셈블리에 있어서, 드럼을 데크플레이트에 접지시키기 위한 VTR의 드럼 베이스 접지장치에 관한 것이다.The present invention relates to a drum base grounding apparatus of a VTR for grounding a drum to a deck plate in a drum assembly of a video tape recorder (VTR).
종래 VTR의 드럼 어셈블리는 드럼 베이스가 알루미늄합금으로 제작되어 드럼과 데크플레이트를 접지시켰었다.In the drum assembly of the conventional VTR, the drum base is made of aluminum alloy to ground the drum and the deck plate.
이러한 종래의 드럼 접지구조는 드럼을 접지하기 위해 드럼 데크플레이트 상에서 받혀주고 있는 드럼 베이스를 비교적 가격이 높은 알루미늄합금을 사용하게 됨에 따라 원가 상승의 요인이 되었다.This conventional drum grounding structure has become a factor of cost increase due to the use of a relatively expensive aluminum alloy for the drum base supported on the drum deck plate to ground the drum.
본 고안은 이와 같은 VTR의 드럼 어셈블리에서 야기되는 원가 상승의 문제점을 해결할 수 있는 접지 구조를 제공하기 위한 것이다.The present invention is to provide a grounding structure that can solve the problem of cost increase caused by the drum assembly of the VTR.
이와 같은 목적을 달성하기 위한 본 고안은, 합성수지로 제작되는 드럼 베이스와, 상기 드럼 베이스 상에서 한쪽은 데크플레이트에 접촉되고, 다른한쪽은 드럼에 접촉되게 놓여지는 접지판과, 상기 접지판이 드럼 베이스에서 유동없이 고정될 수 있도록 하는 고정수단을 포함하는 것을 구조적 특징으로 하는 것이다.The present invention for achieving the above object, the drum base is made of synthetic resin, a ground plate placed on one side of the drum plate and the other side in contact with the drum on the drum base, the ground plate is the drum base It is a structural feature to include a fixing means that can be fixed without flow.
이와 같은 본 고안에 의하면 드럼베이스가 합성수지로 제작됨에 따라 알루미늄합금으로 제작되었던 종래의 드럼베이스보다 저렴하게 제작될 수 있고 데크플레이트와 드럼에 연결되는 접지판에 의해 효과적으로 드럼을 접지시킬 수 있게 되는 것이다.According to the present invention, as the drum base is made of synthetic resin, the drum base can be manufactured cheaper than the conventional drum base made of aluminum alloy, and the drum can be effectively grounded by the ground plate connected to the deck plate and the drum. .
이하, 본 고안의 실시예를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention in detail as follows.
제1도는 본 고안 실시예의 접지판의 사시도이고,1 is a perspective view of a ground plate of an embodiment of the present invention,
제2도는 본 고안의 접지판의 적용된 드럼베이스의 일부를 절개한 단면도이다.2 is a cross-sectional view of a part of an applied drum base of the ground plate of the present invention.
이에 도시한 바와 같이 본 고안의 접지판(1)은 기판(2)으로 부터 형성되어 한쪽은 합성수지로 제작된 데크플레이트(3)에 연결되는 데크연결부(4)와, 다른 한쪽은 드럼(5)에 연결되는 드럼연결부(6)로 형성된다.As shown therein, the ground plate 1 of the present invention is formed from the substrate 2, one side of which is connected to the deck plate 3 made of synthetic resin, and the other side of the drum 5 It is formed of a drum connecting portion 6 connected to.
데크연결부(4)는 데크플레이트(3)에 나사(7)로 고정되는 드럼베이스(8)의 한쪽 고정부위(9)상부에 올려 놓여지면서, 나사(7)가 삽입되는 통공(10)이 형성되어 체결되는 나사(7)에 의해 데크플레이트(3)와 통전된다.The deck connection part 4 is placed on the upper side of one fixing part 9 of the drum base 8 fixed by the screw 7 to the deck plate 3, and the through hole 10 into which the screw 7 is inserted is formed. And the deck plate 3 is energized by the screw 7 which is fastened.
드럼연결부(6)는 드럼베이스(8)의 후위에 형성되는 공간부(S)의 측벽에 밀착될 수 있도록 기판(2)에 형성되는 절곡부(12a)로부터 드럼(5)이 안착되는 드럼베이스(8)의 저면에 접촉가능하게 절곡되어 나사(7a)가 삽입되는 통공(10a)이 형성되어 있다.The drum connecting portion 6 is a drum base on which the drum 5 is seated from a bent portion 12a formed in the substrate 2 so as to be in close contact with the side wall of the space S formed behind the drum base 8. The through hole 10a is bent so as to be in contact with the bottom of (8) and into which the screw 7a is inserted.
나사(7a)는 드럼 연결부(6)의 저면으로부터 통공(10a)과 드럼베이스(8)에 체결되어 드럼(5)과 접촉된다.The screw 7a is fastened to the through hole 10a and the drum base 8 from the bottom of the drum connecting portion 6 to be in contact with the drum 5.
접지판(1)이 드럼베이스(8)에 유동없이 고정될 수 있게 하는 고정수단은 드럼베이스(8)에 돌출 형성된 돌기(11)과, 접지판(1)이 드럼베이스(8)에 안착될 때 상기 돌기(11)가 삽입되는 걸림부위(12)로 형성되어 접지판(1)을 나사(7)(7a)로 고정할때 유동이 발생하지 않게 된다.The fixing means for allowing the ground plate 1 to be fixed to the drum base 8 without flow includes a projection 11 protruding from the drum base 8 and the ground plate 1 to be seated on the drum base 8. When the protrusion 11 is formed as a locking portion 12 is inserted into the ground plate (1) with a screw (7) (7a) so that no flow occurs.
이와 같은 본 고안은 드럼베이스(8)를 합성수지재로 제작하여 금속재를 사용하였던 종래와 비교할 때 무게가 경감되고 데크플레이트(3)와 드럼(5)에 접촉 연결되는 접지판(1)에 의해 효과적으로 접지할 수 있는 효과가 있는 것이다.The present invention is effective by the ground plate (1) is reduced in weight compared to the conventional use of a metal material by making the drum base (8) made of a synthetic resin material and connected to the deck plate (3) and the drum (5) There is an effect that can be grounded.
