The grounding structure of the sash terminal of the tuner, which is, in particular, bent portions are formed on both sides of the ground terminal of the sash cover which is grounded and ground coupled to the inside of the sash, respectively, the center of the bent portion V-shaped lead coupling groove Since the upper side of the ground lead of the tuner chassis is coupled in the lead coupling groove of the ground terminal, both ends of the ground lead of the tuner chassis are inserted and fixed to the inside of the lead coupling groove formed in the ground terminal of the tuner cover. The coupling force is further increased, and the grounding force due to the contact between the ground terminal of the tuner cover and the ground lead is increased, so that the tuning module It is one of the ground terminal on the chassis of a tuner structure to prevent in advance the malfunction of the ground fault.

일반적으로 TV 또는 VTR 내부의 인쇄회로기판상에 설치되는 전자동조 튜너는, 튜너의 샷시 내측으로 기판을 개재하여 입설되는 접지리드의 상단부가 샷시 커버의 접지단자 하단의 절곡단부와 탄성적으로 접지토록 되어 세트(SET)내의 RF신호를 수신하게 된다.In general, a fully tuned tuner installed on a printed circuit board inside a TV or VTR has an upper end portion of the ground lead, which is placed inside the tuner's chassis through the substrate, to be elastically grounded with a bent end of the ground terminal of the chassis cover. To receive the RF signal in the SET.

이와같은 기술과 관련된 종래의 튜너 샷시단자 접지구조에 있어서는 도1 및 도2에 도시한 바와같이, 튜너(31)의 샷시(32) 내측으로 다수의 접지리드(33)가 돌출 설치되며, 상기 튜너(31) 샷시 커버(34)에는 일부가 절결되어 하방으로 절곡된 접지단자(35)가 설치되어 그 일단의 절곡부(36)가 상기 샷시(32)의 접지리드(33)와 접촉되어 접속토록 되는 구조로 이루어진다.In the conventional tuner chassis terminal grounding structure related to such a technique, as shown in FIGS. 1 and 2, a plurality of ground leads 33 protrude and install into the chassis 32 of the tuner 31, and the tuner (31) The sash cover 34 is provided with a ground terminal 35 partially bent and bent downward so that one end of the bent portion 36 is in contact with the ground lead 33 of the sash 32. It is made of a structure.

상기와 같은 결합구조를 갖는 종래의 접지단자(35) 및 접지리드(33)는, 도2에 도시한 바와같이, 샷시 커버(34)상에 일부가 절곡되어 하측으로 경사진 접지단자(35)의 일단부인 절곡부(36)가 샷시(32) 내측의 접지리드(33) 상단부와 탄성적으로 접촉하여 상호 접지토록 되는 것이다.In the conventional ground terminal 35 and the ground lead 33 having the coupling structure as described above, as shown in FIG. 2, the ground terminal 35 bent partially downward on the chassis cover 34 and inclined downward. One end of the bent part 36 is to be in contact with the upper end of the ground lead 33 inside the sash 32 to be grounded to each other.
