본 고안은 전기 계기용 요오크(yoke)에 관한 것으로 특히 가동코일형 계기의 요오크에 관한 것이다.The present invention relates to yokes for electric instruments, and more particularly to yokes of movable coil type instruments.
종래의 가동 코일형 계기에 있어서는 가동코일실과 자석실이 형성된 수매의 극편을 겹쳐서 되는 요오크 몸체를 서로 대칭되게 한 다음 비자성체편을 앞뒤로 하여 리베이팅시켜 고정시키고 형성되는 자석실에는 6방체의 자석을 삽입시키고 일측 비자성체편에 연장되는 돌편을 접으므로서 자석실내의 영구자석이 빠져나오지 못하도록 하는 것이므로, 6방체의 자석을 규격에 맞추어 끼우기 위하여는 원자석을 절단하고 깎어야하며 깎은 면을 연마하여야 하므로 많은 일손과 시간의 소요로 대량 생산하기가 아주 어려웠다.In the conventional movable coil type instrument, the yoke bodies, which overlap the pole pieces of the movable coil chamber and the magnet chamber formed with each other, are symmetrical with each other, and then, by revolving and fixing the nonmagnetic body back and forth, the magnet chamber of six cubes is formed. Since the permanent magnet in the magnet chamber is prevented from being pulled out by folding the stone piece extending to one side of the nonmagnetic material piece, in order to fit the magnet of the hexagonal cube to the standard, the atomic stone must be cut and cut, and the cut surface is polished. Because of the large amount of hands and time required, mass production was very difficult.
본 고안은 상기와 같은 종래의 결점과 비생산성을 시정하기 위하여 자석실에 원주형 자석을 수납하도록 비자성체편에는 4각의 창문이 천공되어 자석실에 수납되는 원주형자석의 주면이 닿아 요동을 방지하며 자력의 세기를 항시 일정하게 함으로서 측정시의 오차를 줄이고또 조립이 간단하여 자동화 기계에 의한 대량생산을 꾀할 수 있도록 한 것으로서 이하 본 고안을 첨부된 도면에 따라 상술한다.The present invention is designed to accommodate cylindrical defects in the magnetic chamber in order to correct the above-mentioned drawbacks and non-productivity. By preventing the constant strength of the magnetic force at all times to reduce the error in the measurement and assembling to facilitate mass production by an automated machine, the present invention will be described in detail below with reference to the accompanying drawings.
제1도는 본 고안을 설명키 위한 사시도로 서로 대치되며 여러장의 코어를 겹쳐서 한쌍의 자극(1, 1')으로 되고 이와 같은 자극(1, 1')에는 서로 대칭되게 가동코일실(3)과 자석실(4)이 형성되며, 상기한 한쌍의 자극(1, 1')의 양면에 비자성의 금속판(5, 6)을 대고 리베이트(7)로 자극(1, 1')에 리베이팅하여서되는 요오크에 있어서, 상기한 비자성의 금속판(5, 6)에는 장홈(8, 9)이 천공되어 있으며, 이와 같은 장공(8, 9)을 서로 마주하여 영구자석(2, 2')을 협지시켜 상기한 자석실(4)에 영구자석(2, 2')을 수납토록 되는 것이다.1 is a perspective view for explaining the present invention and is replaced with each other and overlaps a plurality of cores to form a pair of magnetic poles (1, 1 '), such that the movable coil chamber (3) and the symmetrical to each other A magnet chamber 4 is formed, which is formed by placing a non-magnetic metal plate 5, 6 on both sides of the pair of magnetic poles 1, 1 ′ and rebating the magnetic poles 1, 1 ′ with a rebate 7. In the yoke, long grooves 8 and 9 are drilled in the non-magnetic metal plates 5 and 6, and the permanent magnets 2 and 2 'are sandwiched by facing the long holes 8 and 9. Permanent magnets 2 and 2 'are stored in the magnet chamber 4.
도면중 미설명 부호 10은 자극편(1, 1')에 천공된 구멍(13)을 통해 관통되며, 일측에는 도시하지 않은 계기의 눈금판을 타측에는 도시하지 않은 계기 박스에 고정토록하는 원통형 너트를 의미하며, 11은자형 비자성 금속마개로 자석실(4)에 수납되는 영구자석(2, 2')을 덮는 덮개이며, 금속판(6)에 연장된 연장편(12)을 절곡시켜 이탈하지 않도록 지지하는 것이다.In the drawing, reference numeral 10 denotes a cylindrical nut that penetrates through a hole 13 drilled in the pole pieces 1 and 1 ', and fixes the scale plate of the instrument not shown on one side to the instrument box not shown on the other side. 11 means It is a cover which covers the permanent magnets 2 and 2 'accommodated in the magnet chamber 4 with a magnetic nonmagnetic metal stopper, and supports the extension piece 12 extended to the metal plate 6 so that it may not be bent | deviated.
상기와 같은 구성으로 되는 것이므로 비자성의 금속판(5, 6)에 천공된 장공(8)과 (9)사이에 원주형자석(2, 2')을 협지시켜 대칭되는 자극(1, 1')에 형성된 자석실(4)에 도시하지 않은 자동화 기계에 의해 넣을 수가 있고, 또 이와같이 협지된 상태에서 리베이트(7)로 정확히 리베이팅 할수가 있고 이와같은 조립과정은 모두가 산업적으로 대량 생산할수 있는 실용적인 고안인 것이다.Since the structure is as described above, the magnetic poles 1 and 1 'are symmetrical by sandwiching the columnar magnets 2 and 2' between the holes 8 and 9 drilled in the non-magnetic metal plates 5 and 6, respectively. It can be put into the formed magnet chamber 4 by an automatic machine (not shown), and can be accurately rebated with the rebate 7 in such a sandwiched state, and this assembly process is practically designed for industrial mass production. It is
