* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 절연체 2,5,5′ : 전극피막1: Insulator 2,5,5 ′: Electrode coating
4 : 유전체 A : 가변콘덴서4: dielectric A: variable capacitor
본 고안은 초고주파 회로에 사용되는 가변콘덴서의 구조 개량에 관한 것으로, 특히 접속도체가 없는 직렬콘덴서로 구성되게 한 가변콘덴서에 관한 것이다.The present invention relates to an improvement of the structure of a variable capacitor used in a microwave circuit, and more particularly, to a variable capacitor configured to be a series capacitor without a connecting conductor.
종래에 알려진 고주파용 트리머 콘덴서의 구성은 도체로 된 접속축의 상단은 유전체의 상면에 도포된 전극피막과 접속되게 하고 접속축의 하단에는 판스프링을 고정되게 접속시켜 브러쉬 접속핀에 탄발 접촉되게 하고 유전체와 브러쉬 접속판 사이에는 전극피막이 상면에 도포된 절연몸체를 상호 접촉상태로 위치시킨 구조로써, 절연몸체의 전극피막과 접속판에는 각각 전극리드를 접속시킨 구성이다.The conventionally known high frequency trimmer capacitor has a conductor connecting the upper end of the connecting shaft to the electrode coating coated on the upper surface of the dielectric, and a plate spring fixedly connected to the brush connecting pin so as to be in contact with the dielectric. The insulating body coated on the upper surface of the electrode coating is placed in contact with each other between the brush connecting plates, and the electrode leads are connected to the electrode coating of the insulating body and the connecting plate, respectively.
그러나 이와 같이 구성된 종래의 트리머 콘덴서는 접속되는 도체들의 수가 많아짐으로 해서 구조 자체의 분포용량이 커지므로 정전용량을 최소로 조정해도 제로 PF가 나오지 않고 1∼2PF의 용량은 기본적으로 존재하게 되어 제품의 정밀성을 저하시켰으며 접지와의 분포용량이 커져서 초고주파 회로에는 이용이 곤란한 문제점이 있었으며, 또한 판스프링과 브러쉬 접속판 사이에는 접촉불량 및 접속저항이 존재하여 20Ω∼75Ω의 낮은 초고주파 회로 임피던스의 특성(임피던스, 이득, 효율)을 저하시키는 문제점이 있었던 것이다.However, in the conventional trimmer capacitor configured as described above, the number of conductors connected increases the distribution capacity of the structure itself, so that even if the capacitance is minimized, zero PF does not come out and the capacity of 1 to 2 PF is basically present. The precision has been reduced, and the distribution capacity with the ground is increased, making it difficult to use in the microwave circuit. Also, there is a poor contact and connection resistance between the plate spring and the brush connecting plate. There was a problem of lowering impedance, gain, and efficiency.
또한 국내 실용신안공고 89-9401호의 고안인 반고정 자기 콘덴서는 도체 사이를 사프트가 관통하게 되므로 대칭적으로 또다른 콘덴서가 형성되는 것과 동일하게 되어 분포용량이 커지는 그리고 부식되기가 쉬우며 이로 인해 수명이 짧아지고 제조공정에서 매우 복잡한 과정이 필요하다는 문제점이 있었다.In addition, semi-fixed magnetic capacitors, which are designed in Korean Utility Model Publication No. 89-9401, have shafts penetrating between conductors so that they are symmetrically identical to the formation of another capacitor, resulting in increased distribution capacity and easy corrosion. There was a problem that this shortened and very complicated process in the manufacturing process is required.
본 고안은 이와같은 종래의 제반문제점을 해결하기 위하여 안출한 것으로 콘덴서 자체의 구조를 개량하여 분포용량을 갖는 접속도체의 사용을 배제시킴과 동시에 전극피막의 구조를 개량하여 직렬콘덴서를 구성하므로써 미소용량까지 가변시킬 수 있게 되어 정전용량의 조정에 정밀성을 기할 수 있는 것으로, 구조가 단순하여 생산원가를 절감시킬 수 있는 것이다. 첨부된 도면에 의거 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.The present invention has been devised to solve such problems in the related art, and by improving the structure of the capacitor itself, eliminating the use of a connection conductor having a distribution capacity, and improving the structure of the electrode coating, the microcapacitor is formed by constructing a series capacitor. Since it is possible to vary the precision, it is possible to give precision in the adjustment of the capacitance, and the structure is simple, which can reduce the production cost. Referring to the configuration and operation of the present invention in detail based on the accompanying drawings as follows.
상면에 조정용 드라이버홈(1′)을 갖는 절연체(1)의 저면에는형 전극피막(2)을 형성시킴과 동시에 절연체(1)의 외주면에는 다수의 결합용 걸림돌기(3)를 돌설하여 유전체(4)에 회동 가능하게 결합시켜 유전체(4)의 저면에는형 전극피막(5)(5′)에 대향되게 분리 형성함과 동시에 한쌍의 전극리드(6)(6′)를 형성하여 유전체(4)의 전극피막(5)(5′)에 각각 전기적으로 접속되게 하여 가변콘덴서(A)를 구성하였다.On the bottom surface of the insulator 1 having the adjustment driver groove 1 'on the top surface At the same time, a plurality of coupling protrusions 3 are formed on the outer circumferential surface of the insulator 1 and rotatably coupled to the dielectric 4 so as to form the electrode coating film 2 on the bottom surface of the dielectric 4. The electrode film 5 (5 ') is formed so as to face each other, and a pair of electrode leads 6 (6') are formed to be electrically connected to the electrode films 5 (5 ') of the dielectric material 4, respectively. The variable capacitor A was constructed by connecting.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
먼저 정전용량을 조정하기 위해서는 드라이버홈(1)에 드라이버 등의 공구를 꼽고 돌리면 절연체(1)는 걸림돌기(3)에 의해 유전체(4)에 결합된 상태로 소정각도 회전되는 것으로, 제3도에서와 같이 절연체(1)의 회동에 의해 절연체(1)의 전극피막(2)이 유전체(4)의 전극피막(5)(빗줄친 부위)가 완전히 일치되는 지점에서 최대의 정전용량을 갖게 되는 것이며, 유전체(4)의 전극피막(5)에서 완전히 벗어나는 위치(즉, 겹치는 부위가 없는 일정쇄선의 위치)에서 최소용량, 즉, 제로 PF가 되는것이다.First, in order to adjust the capacitance, plug a tool such as a screwdriver into the driver groove 1 and turn the insulator 1 to be rotated by a predetermined angle while being coupled to the dielectric material 4 by the locking protrusion 3. As shown in FIG. 2, the electrode coating 2 of the insulator 1 has the maximum capacitance at the point where the electrode coating 5 of the dielectric 4 (the hatched portion) is completely matched by the rotation of the insulator 1. At the position completely deviating from the electrode film 5 of the dielectric 4 (i.e., the position of a constant chain line without overlapping portions), the minimum capacity, i.e., zero PF, is obtained.
본 고안은 유전체(4)에 도포된 전극피막(5)(5′)을 분리시켜 구성하고 절연체(1)의 전극피막(2)을 일체로 형성함으로써, 제4도의 회로도와 같이 직렬콘덴서를 이루게 하므로써 미소용량까지 가변이 가능해지며 종래와 같은 접속도체들의 사용을 배제시킴으로써 종래의 가변콘덴서에 비해 접촉불량 및 접촉저항을 발생시키지 않으며 분포용량을 갖지 않아 제로 PF에 가까운 최소용량까지 조절할 수 있고 또한 구조가 간단하여 생산원가가 절감됨과 동시에 대량생산이 가능해지며 구조의 단순화로 인한 부품의 불량이나 고장 등을 감소시킬 수 있어 수명을 연장시킬 수 있는 것이다.The present invention is constructed by separating the electrode coatings 5 and 5 'coated on the dielectric 4 and integrally forming the electrode coating 2 of the insulator 1 to form a series capacitor as shown in the circuit diagram of FIG. This makes it possible to vary the microcapacity, and by eliminating the use of conventional connection conductors, it does not generate poor contact or contact resistance compared to the conventional variable capacitors and does not have a distribution capacity so that the minimum capacity close to zero PF can be adjusted. It is possible to reduce the production cost and mass production at the same time, and to extend the service life by reducing the defects and failures of parts due to the simplified structure.
