As a result, deformation of the terminal 15b occurs, which causes a disadvantage.

본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위하여 창출된 것으로, 본 발명의 목적은 단자를 변형시키지 않고 단자와 PCB를 결합하여 불량율을 감소시킬 수 있는 튜너를 제공함에 있다.The present invention was created to solve the problems of the prior art as described above, an object of the present invention is to provide a tuner that can reduce the defective rate by combining the terminal and the PCB without modifying the terminal.

상기 목적을 달성하기 위한 본 발명에 따른 튜너는 새시, 상기 새시의 내부에 설치되며 관통공이 형성된 PCB, 상기 새시의 외면에 결합되는 몸체와 일측은 상기 몸체의 내부에 결합되고 타측은 상기 몸체의 외측으로 돌출되어 상기 PCB에 접속되는 단자를 가지는 잭을 구비하는 튜너에 있어서,Tuner according to the present invention for achieving the above object is installed in the chassis, the inside of the chassis and the through-hole is formed, the body and one side coupled to the outer surface of the chassis is coupled to the inside of the body and the other side of the outside of the body A tuner having a jack having a terminal protruding from and connected to the PCB,

상기 단자에는 상기 PCB의 저면측에서 상기 관통공으로 유입되는 땜납을 수용하여 상기 땜납에 의하여 상기 PCB와 상기 단자가 납땜되게 하는 수용공이 형성된다.The terminal is provided with a receiving hole for receiving the solder flowing into the through hole from the bottom surface side of the PCB so that the PCB and the terminal is soldered by the solder.

이하, 첨부한 도면을 참조하여 본 발명의 일 실시예에 따른 튜너를 상세히 설명한다.Hereinafter, a tuner according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일 실시예에 따른 튜너의 일부 분해 사시도이고, 도 3은 도 2의 결합 정면도이다.2 is a partially exploded perspective view of a tuner according to an embodiment of the present invention, Figure 3 is a combined front view of FIG.

It has a jack 130 is inserted into the ball 111 is coupled.

잭(130)은 원통형상의 몸체(131)와 일측은 몸체(131)의 내부에 위치되고 타측은 몸체(131)의 외부로 돌출되어 PCB(120)에 접속되는 단자(135)를 가진다. 몸체(131)의 일단부측 외주면에는 새시(110)의 외면과 접촉되는 접촉테(131a)가 형성되고, 몸체(131)의 일단부는 새시(110)의 결합공(111)에 삽입되어 새시(110)의 내면에 코킹(Caulking)된다. 이로인해, 몸체(131)가 새시(110)가 결합된다. Jack 130 has a cylindrical body 131 and one side is located inside the body 131 and the other side has a terminal 135 protruding out of the body 131 is connected to the PCB 120. A contact frame 131a is formed on an outer circumferential surface of one end side of the body 131 to be in contact with the outer surface of the chassis 110, and one end of the body 131 is inserted into a coupling hole 111 of the chassis 110 to allow the chassis 110 to be contacted. Caulking on the inner surface of). Due to this, the body 131 is coupled to the chassis 110.

본 실시예에 따른 튜너(100)는 잭(130)의 단자(135)를 변형시키지 않고 단자 (135)를 PCB(120)에 결합할 수 있도록 마련된다. 상세히 설명하면, 몸체(131)의 외측으로 돌출되어 새시(110)의 내측에 위치된 단자(135)의 타측은 PCB(120)의 상면과 접촉된다. 그리고, 단자(135)의 타측 부위에는 PCB(120)에 형성된 관통공(121)과 연통되는 수용공(135a)이 형성된다. 그리하여, PCB(120)의 저면측에서 땜납(150)을 도포하면, 땜납(150)은 PCB(120)의 관통공(121)으로 유입되어 단자(135)의 수용공(135a)의 유입된다. 그러면, 관통공(121)과 수용공(135a)에 유입된 땜납(150)에 의하여 PCB(120)와 단자(135)가 결합되는 것이다.The tuner 100 according to the present embodiment is provided to couple the terminal 135 to the PCB 120 without deforming the terminal 135 of the jack 130. In detail, the other side of the terminal 135 protruding outward of the body 131 and positioned inside the chassis 110 is in contact with the upper surface of the PCB 120. The receiving hole 135a communicating with the through hole 121 formed in the PCB 120 is formed at the other side of the terminal 135. Thus, when the solder 150 is applied on the bottom surface side of the PCB 120, the solder 150 flows into the through hole 121 of the PCB 120 and flows into the receiving hole 135a of the terminal 135. Then, the PCB 120 and the terminal 135 are coupled by the solder 150 introduced into the through hole 121 and the receiving hole 135a.

이상에서 설명한 바와 같이 본 발명에 따른 튜너는 PCB의 상면과 접촉되게 잭의 단자를 설치하고, PCB의 관통공과 연통되는 수용공을 단자에 형성한다. 그러면, PCB의 저면측에서 PCB의 관통공으로 유입되는 땜납이 단자의 수용공으로 유입되어 PCB와 단자가 납땜되므로 단자의 변형없이 PCB와 단자를 결합할 수 있다. 그러므로, 제품의 불량율이 감소된다.As described above, the tuner according to the present invention installs a terminal of the jack to contact the upper surface of the PCB, and forms a receiving hole in the terminal to communicate with the through-hole of the PCB. Then, the solder flowing into the through hole of the PCB from the bottom side of the PCB flows into the receiving hole of the terminal and the PCB and the terminal are soldered so that the PCB and the terminal can be combined without deformation of the terminal. Therefore, the defective rate of the product is reduced.

이상에서는, 본 발명의 일 실시예에 따라 본 발명을 설명하였지만, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 변경 및 변형한 것도 본 발명에 속함은 당연하다.In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention.
