[산업상의 이용분야][Industrial use]
본 고안은 가변저항기의 리드단자결합장치에 관한 것으로, 특히 리드단자 끝에 U자형 결합돌기가 형성됨으로써 리드단자와 저항기판의 결합력이 향상되고 제품의 제조공정이 간단해지도록 된 가변저항기의 리드단자결합장치에 관한 것이다.The present invention relates to a lead terminal coupling device of a variable resistor, and in particular, a U-shaped coupling protrusion is formed at the end of the lead terminal to improve the coupling force between the lead terminal and the resistor plate and to simplify the manufacturing process of the product. Relates to a device.
[종래기술 및 그 문제점][Prior Art and Problems]
종래의 가변저항기의 리드단자결합장치는 제 1 도에 도시된 바와 같이, 리드프레임본체(1)에 형성된 리드단자(2)상에 원통형 결합돌기(4")가 형성되어, 이 결합돌기(4")가 저항기판의 결합구멍에 끼워져 리벳팅 됨으로써 결합돌기(4)와 저항기판의 저항체가 접속시켜지도록 되어 있었다.In the conventional lead terminal coupling device of a variable resistor, as shown in FIG. 1, a cylindrical coupling protrusion 4 "is formed on a lead terminal 2 formed on the lead frame body 1, and this coupling protrusion 4 is formed. ") Is inserted into the coupling hole of the resistor plate and riveted to connect the coupling protrusion 4 with the resistor of the resistor plate.
그런데 이와 같이 종래의 리드단자 결합장치는, 결합돌기(4")가 저항기판의 결합구멍에 끼워진 상태에서 리벳팅됨으로써 저항기판과의 결합상태가 유지시켜지도록 되어 있기 때문에 리벳팅공정시 저항기판이 파손될 우려가 있게 될 뿐만 아니라 리벳팅공정직전에 결합돌기의 직경(4")이 결합구멍보다 작게 되어 있어서 그 결합구멍에서 빠지게 되는 경우가 발생하게되고, 특히 편평한 리드단자(2)의 표면에 원통형의 결합돌기(4")를 별개로 형성시키는데 상당한 어려움이 따르고 있었다. 따라서 제품의 불량율이 높았을 뿐만 아니라 제조공정이 원활하게 이루어지지 않고, 또 리벳공정에 따른 가변저항기의 제조 및 조립공정수가 증가하게 되는 것이 문제로 되고 있었다.However, in the conventional lead terminal coupling device, since the coupling protrusion 4 " is inserted into the coupling hole of the resistor plate, the coupling plate 4 " In addition to the possibility of damage, the diameter of the engaging projection 4 "is shorter than that of the coupling hole immediately before the riveting process, so that it may come out of the coupling hole. In particular, the surface of the flat lead terminal 2 may be cylindrical. Significant difficulties have been encountered to separately form the coupling projections (4 "). Therefore, not only the defect rate of the product is high, but also the manufacturing process is not smooth, and the number of manufacturing and assembly processes of the variable resistor according to the riveting process increases It was becoming a problem to be done.
[고안의 목적][Purpose of designation]
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 리드단자 끝에 절곡부와 U자형 결합돌기를 형성하고, 이 결합돌기를 저항기판의 결합구멍에 리벳팅 공정없이 끼워 결합시킴으로써, 상기 결합돌기와 기판간에 안정된 결합상태가 유지되어져 가변저항기의 제조공정이 원활히 이루어지게 될 뿐만 아니라, 결합돌기의 가공이 매우 간단해지게 되어 제품이 제조원가를 낮출 수 있도록 된 가변저항기의 리드단자결합장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, by forming a bent portion and a U-shaped coupling protrusion at the end of the lead terminal, the coupling protrusion is coupled to the coupling hole of the resistor plate without the riveting process, the coupling The stable coupling state between the projections and the substrate is maintained, so that the manufacturing process of the variable resistor is not only smoothly performed, but also the processing of the coupling protrusion becomes very simple, thereby providing a lead terminal coupling device of the variable resistor which enables the product to lower the manufacturing cost. The purpose is.
[고안의 구성][Composition of design]
상기와 같은 목적을 달성하기 위한 본 고안은, 리드프레임본체(1)에 다수의 리드단자(2)가 형성되면서, 이 리드단자(2)의 끝에는 절곡부(3)가 형성되고, 이 절곡부(3)끝에는 U자형 결합돌기(4)가 형성되어, 이 절곡부(3)끝에는 U자형 결합돌기(4)가 형성되어, 이 결합돌기(4)가 저항기판(5)의 결합구멍(6)에 끼워져 결합된 구조로 되어 있다.The present invention for achieving the above object, while the plurality of lead terminals 2 are formed in the lead frame body 1, the bent portion 3 is formed at the end of the lead terminal 2, this bent portion (3) The U-shaped coupling protrusion 4 is formed at the end, and the U-shaped coupling protrusion 4 is formed at the bent portion 3, and the coupling protrusion 4 is the coupling hole 6 of the resistor plate 5. It is fitted in the structure.
[작용][Action]
이항 도면을 참조하여 본 고안을 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.
제 2 도는 본 고안에 따른 리드프레임의 사시도로서, 리드프레임본체(1)에는 다수의 리드단자(2)가 형성되면서, 이 리드단자(2)끝에는 U자형 결합돌기(4)를 갖춘 절곡부(3)가 형성되어 있는데, 상기 U자형 결합돌기(4)는 절곡작업으로 간단히 형성시켜질 뿐만 아니라, 리벳팅공정을 거치지 않고 저항기판(5)의 결합구멍(6)에 끼워져 쉽게 빠지지 않게 되므로, 가변저항기의 제조공정이 간단하고 원활히 이루어지게 된다.2 is a perspective view of a lead frame according to the present invention, the lead frame body (1) is formed with a plurality of lead terminals (2), at the end of the lead terminal (2) bent portion having a U-shaped engaging projection (4) ( 3) is formed, the U-shaped coupling protrusion (4) is not only easily formed by bending work, but also fits into the coupling hole (6) of the resistor plate (5) without undergoing a riveting process, so that it does not easily fall out, The manufacturing process of the variable resistor is simple and smooth.
즉, U자형 결합돌기(4)는 그 모양이 용이하게 U자로 형성된 다음 결합구멍(6)의 안쪽에 많이 밀착되게 되므로, 결합구멍(6)보다 직경이 작은 종래의 결합돌기(4")에 비해 쉽게 빠지지 않게 된다.That is, since the U-shaped coupling protrusion 4 is easily formed in a U shape and then closely adheres to the inside of the coupling hole 6, the U-shaped coupling protrusion 4 has a diameter smaller than that of the conventional coupling protrusion 4 ". It does not fall easily.
한편 제 3a~f 도를 참조로 본 발명에는 따른 리드단자(2)의 형성과정과 이 리드단자(2)와 저항기판(5)과의 조립과정에 대해 설명한다.Meanwhile, the process of forming the lead terminal 2 and the assembling process of the lead terminal 2 and the resistor plate 5 will be described with reference to FIGS. 3A to 3F.
먼저 제 3a 도 나타내어진 바와 같이 리드프레임본체(1)와 결합돌기형성부(4"), 절곡부형성부(3') 및 리그단자(2)를 갖춘 리드프레임을 형성시킨 다음, 제 3b 도에 나타내어진 바와 같이 상기 절곡부형성부(3')를 리드단자(2)와 수직되게 절곡시켜 절곡부(3)를 형성시키며, 이어 제 3 도에 나타난 바와 같이 결합돌기형성부(4')를 리드프레임본체(4)쪽으로 U자형으로 굽혀 U자형 결합돌기(4)를 형성시킨다.First, as shown in FIG. 3A, a lead frame having a lead frame body 1, a coupling protrusion forming portion 4 ", a bent portion forming portion 3 ', and a rig terminal 2 is formed. As shown, the bent portion forming portion 3 'is bent perpendicularly to the lead terminal 2 to form the bent portion 3, and then the engaging projection forming portion 4' is read as shown in FIG. The U-shaped coupling protrusion 4 is formed by bending the U-shaped toward the frame body 4.
이와 같이 U자형 결합돌기(4)를 갖춘 리드단자(2)가 형성시켜지게 되면, 제 3d 도에 도시된 바와 같이 U자형의 결합돌기(4)를 저항기판(5)의 결합구멍(6)에 끼워결합시켜 저항체(8)와 연결시키고 나서, 제 3e 도에 도시된 바와 같이 저항기판(5)의 결합구멍(6)부위에 몰딩작업을 행하여 각 리드단자(2)와 저항기판(5)을 확고히 고정시킨 다음, 제 3f 도에 나타낸 바와 같이 케이스(7)를 몰딩해서 형성시킴으로써, 리드단자(2)와 저항기판(5)의 조립을 끝마치게 된다.When the lead terminal 2 having the U-shaped coupling protrusion 4 is formed as described above, the U-shaped coupling protrusion 4 is connected to the coupling hole 6 of the resistor plate 5 as shown in FIG. 3D. Connected to the resistor 8, and then molded into the coupling hole 6 of the resistor plate 5, as shown in FIG. 3E, to each of the lead terminals 2 and the resistor plate 5; Then, the case 7 is molded and formed as shown in FIG. 3F, thereby completing the assembly of the lead terminal 2 and the resistor plate 5.
상술한 바와 같이 본 고안은 리드단자(2)에 U자형의 결합돌기(4)가 형성되어 이 결합돌기(4)가 저항기판(5)의 결합구멍(6)에 결합시켜지게 됨으로써, 조립공정도중에 저항기판(5)으로부터 리드단자(2)의 결합돌기(4)가 빠지지 않게 될 뿐만 아니라, 결합돌기(4)가 간단한 절곡작업으로 형성됨으써 전체조립공정이 훨씬 용이한 쪽으로 전환되게 된다.As described above, in the present invention, the U-shaped coupling protrusion 4 is formed on the lead terminal 2 so that the coupling protrusion 4 is coupled to the coupling hole 6 of the resistor plate 5, thereby assembling the process. Not only does the coupling protrusion 4 of the lead terminal 2 fall out of the resistor plate 5 on the way, but the coupling protrusion 4 is formed by a simple bending operation, so that the whole assembly process is switched to a much easier side.
[고안의 효과][Effect of design]
상기와 같이 본 고안에 의하면, 종래의 원통형 결합돌기(4")와는 달리 U자형 결합돌기(4)가 절곡작업으로 극히 간단히 형성시켜지게 되고, 또 종래와 같은 리벳팅 공정을 행하지 않고서도 결합돌기(4)가 저항기판(5)의 결합구멍(6)에 끼워져 쉽게 빠지지 않게 됨으로써, 가변저항기의 제조공정을 용이한 방법으로 전환시키면서 제품의 제조원가를 낮출 수 있게 된다.According to the present invention as described above, unlike the conventional cylindrical coupling projection (4 ") U-shaped coupling projection (4) is extremely simple to be formed by bending work, and also without engaging the conventional riveting process (4) is inserted into the coupling hole 6 of the resistor plate 5 so as not to be easily pulled out, thereby reducing the manufacturing cost of the product while switching the manufacturing process of the variable resistor into an easy method.
