본 고안은 NMR-CT(핵자기 전산화 공명 단층 촬영기)에 사용되는 것으로, 특히 고전압에도 방전하지 않도록함을 기구적인 구성으로 적당하게 한 고압 논 마그네틱 고주파트리머 캐패시터에 관한 것이다.The present invention is used for NMR-CT (nuclear magnetic computerized resonance tomography), and particularly relates to a high-pressure non-magnetic high frequency trimmer capacitor that has a suitable mechanical configuration to prevent discharge even at high voltage.
종래의 캐패시터는 제1도에 도시한 외구성과 제2도에 도시한 내부구성 및 회로구성을 갖추어서 제1도의 외부모양에서 밖으로 노출된 손잡이를 잡고 가변시키면 원하는 캐패시터 값을 변동시킬 수 있도록 구성되었다.The conventional capacitor has the external configuration shown in FIG. 1 and the internal configuration and circuit configuration shown in FIG. 2 so that the desired capacitor value can be changed by holding and changing the handle exposed outside from the external shape of FIG. It became.
이러한 종래의 캐패시터는 100W의 인두를 사용하는 기구에 취부시키는 데에 있어서 기존의 캐패시터들은 열에 약하여 내부코일이 단락되어 사용하지 못하는 사례가 종종 발생하였다.In the case of the conventional capacitor, which is mounted on an apparatus using a 100 W iron, conventional capacitors are weak in heat, and the internal coils are often shorted and cannot be used.
그리고, 기존의 캐패시터는 40MHZ 대역까지의 사용례가 나오 있으나 통상적을 사용되는 주파수로 85MHZ 대역이라서 전류대 주파수가 적합하지 않았고 또 기존의 캐패시터는 가격이 비싸서 주문생산을 해온 관계로 적절한 때에 사용하지 못하는 취약점을 갖고 있는 것이다.In addition, the existing capacitor has a use case up to 40MHZ band, but the current frequency is 85MHZ band as the commonly used frequency, and the current capacitor frequency was not suitable. To have.
본 고안은 이러한 점을 감안하여 고안한 것으로서 본체에 결합되어 이동되면서 정전용량을 조절하는 조절봉을 테프론으로 형성하고, 본체와 조절봉내에 방전하는 구리봉에 테프론으로 된 테이프를 감아 구성함으로써 고전압에 방전되는 것을 방지하고 캐패시터를 부착시인두의 열에 의하여 파손되는 것을 방지할 수 있도록 하는데 목적이 있다.The present invention has been devised in view of this point, and is formed by teflon adjusting rod that is coupled to the main body and adjusts the capacitance, and is discharged at high voltage by winding a tape made of teflon on the copper rod discharged in the main body and the adjusting rod. The purpose of the present invention is to prevent damage and to prevent damage by the heat of the iron when attaching a capacitor.
본 고안의 구성을 제5도 및 제6도에 의하여 상세히 설명하면 다음과 같다.The configuration of the present invention will be described in detail with reference to FIGS. 5 and 6 as follows.
황동으로된 본체(3)내에 나사부(3a)를 형성하고, 상기 나사부(3a)에 결합되어 이동하면서 정전용량을 조절하는 테프론으로 형성된 조절봉(1)과 상기 본체(3)와 조절봉(1)내에는 전원을 인가하는 구리봉(6)을 구성하였다.An adjustment rod (1) formed of a teflon and a main body (3) and an adjustment rod (1) which form a threaded portion (3a) in the brass body (3) and are coupled to the threaded portion (3a) to adjust capacitance while moving. In (), a copper rod 6 for applying power was configured.
그리고, 상기 조절봉(1)의 외주는 본체(3)내의 나사부(3a)와 나사결합할 수 있도록 한 나사부(1a)를 형성하고 조절봉(1)의 내부에는 전원을 인가하는 구리봉(6)이 삽입되는 삽입홈(1c)를 형성하고, 상기 조절봉(1)의 일단에는 조절봉(1)을 회동시키는 기구가 삽입되는 홈(16)을 형성하며, 상기 전원을 인가하는 구리봉(6)에는 절연체인 테프론 테이프(5)를 감아 형성한다.In addition, the outer circumference of the adjusting rod 1 forms a threaded portion 1a to be screwed with the threaded portion 3a in the main body 3, and a copper rod 6 for applying power to the inside of the adjusting rod 1. The insertion groove (1c) is inserted into the insertion, one end of the adjusting rod (1) forms a groove (16) into which the mechanism for rotating the adjusting rod (1) is inserted, the copper rod (6) for applying the power Is formed by winding the Teflon tape 5 which is an insulator.
상기 본체(1)에 나사결합 된 조절봉(1)의 나사부(1a)에 나사결합되어 조절봉(1)의 유동을 방지하는 고정구(2)를 형성하였다.Screwed to the threaded portion (1a) of the adjusting rod (1) screwed to the main body (1) to form a fixture (2) to prevent the flow of the adjusting rod (1).
도면중 미설명 부호 14는 본체(3)의 일측에 결합되는 캡이고, 14a는 캡(4)에 뚫린 구멍으로서 전원을 인가하는 구리봉(6)이 삽입되는 것이다.In the figure, reference numeral 14 denotes a cap coupled to one side of the main body 3, and 14a denotes a hole drilled in the cap 4 to insert a copper rod 6 for applying power.
이상과 같이 구성된 본 고안의 작용효과를 제5도 및 제6도에 의하여 설명한다.Effects of the present invention configured as described above will be described with reference to FIGS. 5 and 6.
이와 같이 구성된 상태에서 본체(3)와 구리봉(6)에는 두라인을 신호와 접지로 사용하는데 캐패시터 값을 조절코져할 때는 조절봉(1)에 형성된 홈(1b)에 기구를 끼워 돌리면 조절봉(1)이 회동된다.In this state, the main body 3 and the copper rod 6 use two lines as signals and grounds. When adjusting the capacitor value, the mechanism is inserted into the groove 1b formed in the adjusting rod 1 by turning the adjusting rod ( 1) is rotated.
따라서 조절봉(1)이 회전함에 따라 캐패시터 값이 조절되는 것이다.Therefore, the capacitor value is adjusted as the adjusting rod 1 rotates.
그리고, 회전된 조절봉(1)은 고정구(2)에 의하여 고정되는데 즉, 조절봉(1)에 나사결합된 고정구(2)를 돌려서 본체(3)의 일단에 밀착되게 조이면 조절봉(1)와 움직이지 아니하고 본체(3)에 고정된다.Then, the rotated adjustment rod (1) is fixed by the fastener (2), that is, by turning the fastener (2) screwed to the adjustment rod (1) and tightly attached to one end of the main body (3) adjustment rod (1) It is fixed to the main body 3 without moving.
그리고, 구리봉(6)에 감긴 테이프(5)는 절연체인 테프론을 형성되어 있기 때문에 본체(3)와 구리봉(6)의 사이에서 절연작용을 하게 된다.Since the tape 5 wound on the copper rod 6 is formed of Teflon which is an insulator, the tape 5 is insulated between the main body 3 and the copper rod 6.
따라서 고전압에 방전되는 것을 방지할 수 있다.Therefore, discharge to a high voltage can be prevented.
이와같은 본 고안은 캐패시터 작용은 본체와 공기의 전도성을 이용하여 캐패시터의 값을 가변할 수 있는 것으로서 조절봉의 삽입홈 직경과 구리봉의 굵기를 조절하여 5PF∼20PF까지 원하는 캐패시터를 사용할 수 있는 것이다.The present invention as described above, the capacitor action is to change the value of the capacitor by using the conductivity of the body and the air is to use the desired capacitor up to 5PF ~ 20PF by adjusting the insertion groove diameter of the adjustment rod and the thickness of the copper rod.
그리고, 종래의 캐패시터는 열에 약하여 파손될 우려가 있으나 본 고안은 재질적으로 열에 구애를 받지 아니할 뿐만 아니라 기구적으로서 간단하여 사용이 편리하고 가격면에서도 저렴한 가격을 생산할 수 있는 유용한 고안이다.In addition, the conventional capacitor may be damaged due to weakness of heat, but the present invention is not only subject to heat in terms of material, but is also useful as it is simple to use mechanically and can produce a low price in terms of price.
