본 발명은 튜너의 단자조립체에 관한 것이다.The present invention relates to a terminal assembly of a tuner.

튜너(Tuner)란 무선 수신 장치의 입력부에 사용되는 것으로 일정한 전파 또는 전기신호의 주파수에 동조(同調)하여 그 전파만을 선택하여 꺼내는 장치를 말한다.Tuner is used in the input part of a radio receiver, and refers to a device that tunes to a frequency of a fixed radio wave or an electric signal and selects and extracts only the radio wave.

도 1은 종래의 튜너의 분해 사시도로서, 이를 설명한다.1 is an exploded perspective view of a conventional tuner, which will be described.

도시된 바와 같이, 새시(10)의 상면 및 하면에는 상부 및 하부커버(21,25)가 각각 결합되고, 새시(10)의 내부에는 회로기판(30)이 설치된다. 그리고, 새시(10)의 일측판 내면에는 회로기판(30)에 접속된 제 1 및 제 2 단자조립체(41,45)가 결합된다.As shown, the upper and lower covers 21 and 25 are coupled to the upper and lower surfaces of the chassis 10, respectively, and a circuit board 30 is installed inside the chassis 10. The first and second terminal assemblies 41 and 45 connected to the circuit board 30 are coupled to the inner surface of one side plate of the chassis 10.

제 1 및 제 2 단자조립체(41,45)는 새시(10)에 형성된 관통공(11a,11b)과 각각 대응되게 형성되어 새시(10)의 내면에 각각 결합되는 지지몰드(41a,45a), 지지몰드(41a,45a)에 일체로 형성되며 일단부는 회로기판(30)에 각각 접속되고 타단부는 새시(10)의 외측으로 각각 돌출된 복수의 단자(41b,45b)를 각각 가진다.The first and second terminal assemblies 41 and 45 are formed to correspond to the through-holes 11a and 11b formed in the chassis 10, respectively, and support molds 41a and 45a coupled to the inner surface of the chassis 10, respectively. The support molds 41a and 45a are integrally formed with one end connected to the circuit board 30 and the other end having a plurality of terminals 41b and 45b respectively protruding outward of the chassis 10.

제 1 및 제 2 단자조립체(41,45)를 회로기판(30) 및 새시(10)에 결합하는 방법을 설명한다.A method of coupling the first and second terminal assemblies 41 and 45 to the circuit board 30 and the chassis 10 will now be described.

리플로우(Reflow) 공정상에서 제 1 및 제 2 단자조립체(41,45)의 단자(41b,45b)의 일단부를 회로기판(30)에 납땜한 후, 회로기판(30)과 제 1 및 제 2 단자조립체(41,45)를 새시(10)에 결합한다.After soldering one end of the terminals 41b and 45b of the first and second terminal assemblies 41 and 45 to the circuit board 30 in the reflow process, the circuit board 30 and the first and second terminals are soldered. The terminal assemblies 41 and 45 are coupled to the chassis 10.

제 1 및 제 2 단자조립체(41,45)를 새시(10)에 결합하는 방법은, 제 1 및 제 2 단자조립체(41,45)의 지지몰드(41a,45a)를 새시(10)의 내면에 접촉시킨 상태에서, 관통공(11a,11b) 상하측의 새시(10)의 내면에 각각 형성된 결합돌기(23a,23b)를 지지몰드(41a,45a)측으로 벤딩하여 제 1 및 제 2 단자조립체(41,45)를 새시(10)에 결합한다.The method of coupling the first and second terminal assemblies 41 and 45 to the chassis 10 includes the support molds 41a and 45a of the first and second terminal assemblies 41 and 45 to the inner surface of the chassis 10. In contact with the first and second terminal assemblies by bending the engaging projections 23a and 23b formed on the inner surfaces of the chassis 10 above and below the through holes 11a and 11b toward the support molds 41a and 45a, respectively. (41, 45) is coupled to the chassis (10).

그러나 상기와 같은 종래의 튜너는 제 1 및 제 2 단자조립체(41,45)가 별개로 마련되므로, 제 1 및 제 2 단자조립체(41,45)가 새시(10)에 별도로 각각 결합된다. 그러므로, 제 1 및 제 2 단자조립체(41,45)가 새시(10)에 결합되었을 때, 조립 공차 등에 의하여 제 1 단자조립체(41)의 단자(41b)와 제 2 단자조립체(45)의 단자(45b)가 동일 직선상에 위치되지 못하고 어긋나게 된다. 이로인해, 제 1 및 제 2 단자조립체(41,45)의 단자(41b,45b)를 제품의 연결부에 삽입하기 위해서는, 제 1 및 제 2 단자조립체(41,45)의 단자(41b,45b)가 동일 직선상에 위치되게 교정작업을 별도로 수행하여야 하므로 조립 공정이 번거로운 단점이 있다.However, in the conventional tuner as described above, since the first and second terminal assemblies 41 and 45 are separately provided, the first and second terminal assemblies 41 and 45 are separately coupled to the chassis 10, respectively. Therefore, when the first and second terminal assemblies 41 and 45 are coupled to the chassis 10, the terminals 41b of the first terminal assembly 41 and the terminals of the second terminal assembly 45 may be caused by assembly tolerances or the like. 45b is not located on the same straight line and is shifted. Thus, in order to insert the terminals 41b and 45b of the first and second terminal assemblies 41 and 45 into the connection part of the product, the terminals 41b and 45b of the first and second terminal assemblies 41 and 45 are inserted. Since the calibration must be performed separately so that is located on the same straight line, the assembly process is cumbersome.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 창작된 것으로, 본 발명의 목적은 단자조립체를 새시에 결합한 후, 단자조립체의 단자의 위치를 교정할 필요가 없는 조립 공정이 간편한 튜너를 제공함에 있다.The present invention was created to solve the problems of the prior art as described above, and an object of the present invention is to provide a tuner that is easy to assemble without the need to correct the position of the terminal of the terminal assembly after coupling the terminal assembly to the chassis.

도 2는 본 발명의 일 실시예에 따른 튜너의 분해 사시도이고, 도 3은 도 2에 도시된 새시에 단자조립체가 결합된 상태를 보인 정면도이다.Figure 2 is an exploded perspective view of a tuner according to an embodiment of the present invention, Figure 3 is a front view showing a state in which the terminal assembly is coupled to the chassis shown in FIG.

도시된 바와 같이, 본 실시예에 따른 튜너(100)는 사각 프레임 형상의 새시(110)를 가진다. 새시(110)의 일측판에는 그 형상이 다른 복수의 관통공(111a,111b)이 형성되고, 관통공(111a,111b) 상하측 부위의 새시(110)의 내면에는 후술할 단자조립체(140)의 지지몰드(141)를 지지하는 복수의 결합돌기(113a,113b)가 형성된다.As shown, the tuner 100 according to the present embodiment has a chassis 110 having a rectangular frame shape. A plurality of through holes 111a and 111b having different shapes are formed in one side plate of the chassis 110, and the terminal assembly 140 to be described later on the inner surface of the chassis 110 of upper and lower portions of the through holes 111a and 111b. A plurality of coupling protrusions 113a and 113b supporting the support mold 141 is formed.

새시(110)의 상하면에는 상부 및 하부커버(121,125)가 각각 결합되고, 새시(110)의 내부에는 회로가 인쇄되고 복수의 전자부품이 설치된 회로기판(130)이 결합된다. 그리고, 새시(110)의 내면에는 회로기판(130)과 접속되는 단자조립체(140)가 결합된다.Upper and lower surfaces 121 and 125 are coupled to the upper and lower surfaces of the chassis 110, respectively, and a circuit printed on the inside of the chassis 110 is coupled to a circuit board 130 on which a plurality of electronic components are installed. In addition, a terminal assembly 140 connected to the circuit board 130 is coupled to the inner surface of the chassis 110.

단자조립체(140)는 지지몰드(141)와 단자(145)를 가진다. 지지몰드(141)는 각 관통공(111a,111b)의 형상과 대응되는 형상을 가지는 복수의 지지몰드가 일체로 형성된 형태를 이루고, 단자(145)는 지지몰드(141)에 삽입되어 지지된다. 이때, 단자(145)의 일단부는 회로기판(130)에 납땜되어 접속되고, 타단부는 새시(110)의 외측으로 돌출된다.The terminal assembly 140 has a support mold 141 and a terminal 145. The support mold 141 has a form in which a plurality of support molds having shapes corresponding to the shapes of the through holes 111a and 111b are integrally formed, and the terminal 145 is inserted into and supported by the support mold 141. In this case, one end of the terminal 145 is soldered and connected to the circuit board 130, and the other end protrudes out of the chassis 110.

본 실시예에 따른 단자조립체(140)를 회로기판(130) 및 새시(110)에 결합하는 방법을 설명한다.A method of coupling the terminal assembly 140 to the circuit board 130 and the chassis 110 according to the present embodiment will be described.

먼저, 단자(145)의 타단부가 새시(10)의 외측으로 돌출되도록 새시(110)의 내측에서 외측으로 단자(145)의 타단부를 삽입한 후, 회로기판(130)을 새시(110)에 결합한다. 그러면, 지지몰드(141)가 새시(110)의 내면과 접촉되는데, 이 상태에서 결합돌기(113a,113b)를 벤딩하여 단자조립체(140)를 새시(110)에 결합한다. 그 후, 리플로우(Reflow) 공정상에서 단자조립체(140)의 단자(145)의 일단부를 회로기판(30)에 납땜하면 된다.First, the other end of the terminal 145 is inserted into the outside of the chassis 110 from the inside of the chassis 110 so that the other end of the chassis 10 protrudes outwards, and then the circuit board 130 is inserted into the chassis 110. To combine. Then, the support mold 141 is in contact with the inner surface of the chassis 110, in this state to bend the coupling projections (113a, 113b) to couple the terminal assembly 140 to the chassis (110). Thereafter, one end of the terminal 145 of the terminal assembly 140 may be soldered to the circuit board 30 in the reflow process.

본 실시예에 따른 단자조립체(140)는 지지몰드(141)가 일체로 형성되므로, 지지몰드(141)가 새시(110)에 결합되어도, 지지몰드(141)에 지지된 단자(145)의 타단부측은 제조된 최초의 상태와 동일한 상태, 즉, 일직선을 이루면서 새시(110)에 결합된다.In the terminal assembly 140 according to the present exemplary embodiment, since the support mold 141 is integrally formed, the other end of the terminal 145 supported by the support mold 141 may be formed even when the support mold 141 is coupled to the chassis 110. The end side is coupled to the chassis 110 in the same state as the first state produced, ie in a straight line.

이상에서 설명하듯이, 본 발명에 따른 튜너는 단자조립체의 지지몰드가 일체로 형성되므로, 지지몰드가 새시에 결합되어도 지지몰드에 지지된 단자의 위치는 변형이 없다. 그러므로, 조립이 완료된 튜너의 단자의 타단부를 제품의 연결부에 용이하게 삽입하여 결합할 수 있으므로, 조립 공정이 간편하다. As described above, in the tuner according to the present invention, since the support mold of the terminal assembly is integrally formed, the position of the terminal supported by the support mold is not deformed even when the support mold is coupled to the chassis. Therefore, the other end of the assembled terminal of the tuner can be easily inserted and coupled to the connection portion of the product, the assembly process is simple.

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.
