제1도 a는 본 고안 장치의 사시도.1 is a perspective view of the device of the present invention.
b는 본 고안 장치의 분해 사시도.b is an exploded perspective view of the device.
제2도는 종래 고출력 트랜지스터의 콜랙터 인출장치의 분해 사시도.2 is an exploded perspective view of a collector extractor of a conventional high output transistor.
본 고안은 고출력 트랜지스터의 콜랙터를 회로 기판의 동박 패턴에 직접 연결시키기 위한 콜랙터 인출장치의 구조 개량에 관한 것이다.The present invention relates to a structure improvement of a collector extractor for directly connecting a collector of a high output transistor to a copper foil pattern of a circuit board.
종래에는 제2도에서와 같이 고출력 트랜지스터(20)를 방열판(21)에 절연판 (22)을 통하여 절연와샤(23)를 낀 나사(24)로 고정하고 나사(24)를 고정기판(25)에 형성된 구멍(26)을 통하여 돌출시킨 다음 돌출된 나사(24)에 러그단자(27)를 끼운다음 너트(28)로 고정시킨후 러그단자(27)와 회로기판(29)의 동박(30) 사이를 리드선 (31)으로 납땜 연결 하였었다.Conventionally, as shown in FIG. 2, the high output transistor 20 is fixed to the heat sink 21 with a screw 24 having an insulating washer 23 through the insulating plate 22, and the screw 24 is fixed to the fixed substrate 25. After protruding through the formed hole 26, the lug terminal 27 is inserted into the protruding screw 24, and then fixed with a nut 28, and then between the lug terminal 27 and the copper foil 30 of the circuit board 29. Was soldered to the lead wire (31).
그러나 종래의 이러한 연결은 고출력 트랜지스터(20)와 회로기판(29)의 동박 (30)사이를 리드선(31)으로 납땜연결하여야 하므로 리드선 등과 같은 별도 부품이 필요하게 되며 동시에 제조공정이 복잡하여 시간이 많이 걸려서 작업 능률이 떨어진다.However, such a conventional connection requires soldering connection between the high power transistor 20 and the copper foil 30 of the circuit board 29 with the lead wire 31, so that a separate part such as a lead wire is required, and at the same time, the manufacturing process is complicated, It takes a lot of work and it is inefficient.
더우기 고출력 트랜지스터(20)가 고주파 수용 일때에는 연결접속부위가 많아서 고주파수용 특성이 저하된다는 단점이 있었다.Moreover, when the high output transistor 20 receives high frequency, there are many disadvantages in that high connection characteristics are degraded due to a large number of connection and connection portions.
본 고안은 이러한 종래의 단점을 없이하도록 고출력 트랜지스터 몸체에 연결 돌기가 형성된 도전체링을 끼우고 연결돌기를 회로기판의 회로를 구성하는 동박에 직접 납땜하도록하여 구성 부품수를 작게하여 조립시간을 단축시켜서 작업능률을 향상시킴과 동시에 고출력 트랜지스터가 고주파수용일때 고주파수 특성이 저하되지 않는 콜랙터 단자 인출장치를 제공하는 것을 목적으로 하며, 이하 첨부된 도면을 참조하면서 본 고안의 구성, 작용효과를 설명하면 다음과 같다.The present invention inserts a conductor ring with a connecting protrusion formed on the body of a high-output transistor so as to eliminate the above-mentioned disadvantages, and allows the connecting protrusion to be directly soldered to a copper foil constituting a circuit of a circuit board, thereby reducing the assembly time by reducing the number of components. The purpose of the present invention is to provide a collector terminal drawing device which improves work efficiency and does not deteriorate high frequency characteristics when a high output transistor is used for high frequency. Hereinafter, the structure and effect of the present invention will be described with reference to the accompanying drawings. Same as
우선 제1도를 참조하면 본 고안의 구성은, 연결돌기(1)가 일체로 형성된 도전체링(2)을 형성하고, 도전체링(2)의 양측에 나사구멍(3,4)을 형성하여 고출력 트랜지스터(5)의 나사구멍을 통하여 방열판(6)과 회로기판(7)에 나사로 고출력 트랜지스터 (5)를 고정시키고, 회로기판(7)에 형성된 구멍(8)을 통하여 연결돌기(1)를 돌출시켜 회로기판(7)의 회로동박(9)에 납땜시켜된 구성으로서 이러한 본 고안의 구성의 작용효과를 설명하면, 도전체링(2)에 형성된 연결돌기(1)는 도전체링(2)이 고출력 트랜지스터(5)의 콜랙터가 되는 것이며, 이에따라 연결돌기(1)도 콜랙터가 되는 것이다. 이때 접촉 저항은 접촉부위가 넓어지므로 거의 무시할 정도가 되는 것이다.First, referring to FIG. 1, the constitution of the present invention is to form a conductor ring 2 in which the connecting protrusions 1 are integrally formed, and to form screw holes 3 and 4 at both sides of the conductor ring 2, thereby providing a high output. The high output transistor 5 is fixed to the heat sink 6 and the circuit board 7 with a screw hole through the screw hole of the transistor 5, and the connecting protrusion 1 protrudes through the hole 8 formed in the circuit board 7. By explaining the effect of the configuration of the present invention as a configuration that is soldered to the circuit copper foil (9) of the circuit board 7, the connection projection (1) formed in the conductor ring (2) has a high output It becomes a collector of the transistor 5, and the connection protrusion 1 also becomes a collector by this. At this time, the contact resistance is almost negligible because the contact area becomes wider.
또한 연결돌기(1)가 회로기판(7)에 형성된 구멍(8)을 통하여 회로기판(7)의 회로동박(9)에 직접 납땜되므로 결국 고출력 트랜지스터(5)의 콜랙터를 직접 회로동박 (9)에 직접 납땜한 것과 유사하게 되어 고출력 트랜지스터(5)의 고주파 특성이 그대로 유지된다.In addition, since the connecting projection 1 is directly soldered to the circuit copper foil 9 of the circuit board 7 through the hole 8 formed in the circuit board 7, the collector of the high output transistor 5 is directly connected to the circuit copper foil 9. ) And the high frequency characteristics of the high output transistor 5 are maintained.
또한 별도의 리드선이 필요없으며 납땜부위가 줄어들므로 조립공정의 시간이 단축되어 작업율이 향상되는 것이며, 동시에 제품의 품질향상과 신뢰성 향상을 기할 수 있는 것이다.In addition, no separate lead wire is required and the soldering area is reduced, thereby reducing the assembly process time and improving work rate, and at the same time, improving product quality and reliability.
