Description

고정 저항기Fixed resistor

제1도는 본 고안의 일실시예에서의 고정 저항기가 사용되는 전력 증폭기의 회로도.1 is a circuit diagram of a power amplifier in which a fixed resistor in one embodiment of the present invention is used.

제2도는 동 고정 저항기의 구성을 표시한 개략도.2 is a schematic diagram showing the configuration of the same fixed resistor.

제3도는 동 고정 저항기의 요부 사시도.3 is a perspective view of main parts of the same fixed resistor.

본 고안은 고정 저항기에 관한 것으로, 예를들면 2개의 고정 저항이 직렬로 접속되고, 또한 그 접속점 및 다른 자유단에 각각 다른 부품이 접속되도록 배치된 고정 저항기의 개량에 관한 것이다.The present invention relates to a fixed resistor, for example, to an improvement of a fixed resistor arranged so that two fixed resistors are connected in series and different components are connected to their connection points and other free ends, respectively.

예를들면, 제1도에 표시한 바와 같이 NPN형의 출력 트랜지스터(1) 및 PNP형의 출력 트랜지스터(2)의 에미터를 각각의 에미터 저항(3)(4)을 개재하여 공통으로 접속하고, 상기 에미터 저항(3)(4)의 접속점에 부하(5)를 접속하도록 한 전력 증폭기에 있어서, 상기 에미터 저항(3)(4)의 접속은, 종래 고정 저항기를 2개 사용하여, 각각을 소정의 개소에 접속하고 있었다.For example, as shown in FIG. 1, the emitters of the NPN type output transistor 1 and the PNP type output transistor 2 are connected in common via the respective emitter resistors 3 and 4. In the power amplifier in which the load 5 is connected to the connection point of the emitter resistors 3 and 4, the connection of the emitter resistors 3 and 4 is conventionally made using two fixed resistors. , Each was connected to a predetermined location.

본 고안은 상기 2개의 고정 저항기를 1블록화 하고, 또한 저항체를 파상으로 가공함과 동시에 절연체의 상대하는 면에서 각각의 단자를 돌출시키므로서 조립공정수의 저감, 저항체의 무유도화 및 조정작업의 용이화를 꾀한 것이다.The invention devises one block of the two fixed resistors and processes the resistors in a wave shape, and simultaneously protrudes each terminal from the opposite side of the insulator, thereby reducing the number of assembly steps, deriving the resistors, and facilitating adjustment work. I was angry.

이하 그 일실시예에 대하여 제2도, 제3도에 의해 설명한다. 도면에 있어서, (6)(7)(8)은 각각의 단자이고, 이들 단자(6)(7)(8)와 일체화되는, 즉 합성수지제의 절연체(9)의 하면은 물론, 상면으로 부터도 돌출하도록 하고 있으며, 상면 돌출부(6a)(7a)(8a)를 각각의 체크 단자로서 사용할 수 있게 하고 있다. 그리고, 단자(6)와 단자(7)의 사이 및 단자(7)와 단자(8)의 사이에 제1도의 저항(3)(4)에 상당하는 저항체(10)(11)를 접속하고 있다. 이 경우, 저항체(10)(11)는 각각 파상으로 가공해서 소요로하는 저항차를 얻음과 동시에, 무유도화를 꾀하고 있다.Hereinafter, one embodiment will be described with reference to FIGS. 2 and 3. In the drawing, (6) (7) (8) are respective terminals, which are integrated with these terminals (6) (7) (8), that is, from the upper surface as well as the lower surface of the insulator 9 made of synthetic resin. The upper projections 6a, 7a and 8a can be used as respective check terminals. The resistors 10 and 11 corresponding to the resistors 3 and 4 in FIG. 1 are connected between the terminal 6 and the terminal 7 and between the terminal 7 and the terminal 8. . In this case, the resistors 10 and 11 are each processed into a wave shape to obtain the required resistance difference, and also to induce deduction.

상기 구성에 의하면, 먼저 저항체(10)(11) 및 단자(6)(7)(8)를 일체화하므로서, 프린트 기판위에 있어서의 조립공정수의 저감이 도포됨과 동시에 프린트 기판의 사용면적을 작게할 수가 있고, 또 각 저항체(10)(11)를 각각 파상으로 절곡가공하여 배선하므로서 무유도화가 도모되고, 이것에 의해 증폭회로의 고역의 왜율의 개선이 가능하게 되고, 또한 상기 고정 저항기를 사용하는 경우, 절연체(9)의 하면에서 돌출하는 단자부분을 프린트 기판에 삽입하여 납땜하게 되는 것이나, 절연체(9)의 상면 위에도 체크단자(6a)(7a)(8a)로서 단자의 일부를 돌출시키고 있기 때문에, 출력 트랜지스터(1)(2)를 흐르는 전류(I1)(I2)를 측정할 경우, 편리하다.According to the above constitution, the resistors 10, 11, and terminals 6, 7, 8 are first integrated, thereby reducing the number of assembling steps on the printed board and reducing the use area of the printed board. In addition, the inductance can be achieved by bending and wiring the respective resistors 10 and 11 in the form of a wave, respectively, whereby the distortion of the high frequency of the amplification circuit can be improved, and the fixed resistor is used. In this case, the terminal portion protruding from the lower surface of the insulator 9 is inserted into the printed circuit board and soldered, or a part of the terminal is protruded as the check terminals 6a, 7a and 8a on the upper surface of the insulator 9 as well. Therefore, it is convenient when measuring the current I 1 (I 2 ) flowing through the output transistors 1 and 2.

즉, 종래는 상기 전류(I1)(I2)를 측정하기 위해서 저항기와는 별도로 체크단자를 착설하고 있었으나, 본 구성에 의하면 그 체크단자가 불필요하게 된다. 또한, 본 실시예에 있어서는, 상기 저항체(10)(11)로서 비자성체의 구리니켈을 사용하였다. 또, 상기 체크단자는 절연체(9)의 상면이 아니라, 측면이라도 된다.In other words, conventionally, a check terminal was installed separately from the resistor in order to measure the current I 1 (I 2 ). However, according to this configuration, the check terminal is unnecessary. In this embodiment, non-magnetic copper nickel was used as the resistors 10 and 11. The check terminal may be a side surface, not an upper surface of the insulator 9.

이상 설명한 바와 같이 본 고안에 의하면, 적어도 3본의 단자를 점연체를 일체화 하고, 제1의 단자와 공통단자의 사이 및 제2의 단자와 공통단자와의 사이에 각각 저항체를 파상으로 가공하여 접속함과 동시에, 상기 단자와 다른면에 각각 돌출시키므로서, 조립 공정수의 저감, 프린트 기판의 사용면적의 효율화, 저항체의 무유도화, 각 저항체를 흐르는 전류측정의 용이화를 도모할 수 있어 실용상 극히 편리하다.As described above, according to the present invention, at least three terminals are integrally integrated with each other, and a resistor is processed in a wave form between the first terminal and the common terminal and between the second terminal and the common terminal, respectively. At the same time, by projecting to the terminal and the other surface, the number of assembly steps can be reduced, the area of use of the printed board can be reduced, the inductance of the resistors can be reduced, and the current measurement flowing through each resistor can be facilitated. Extremely convenient.
