Title: Cross coil instrument
Inventor: SATO KOICHI
IPC: G01R5/16
Filed: 1994-06-30
Abstract: PURPOSE:To obtain a compact cross coil instrument in which the space for mounting the coin connection terminals is ensured sufficiently without stretching sideways by winding coils orthogonally around a bobbin only on one side of the rotary shaft and mounting the terminals on the opposite side. CONSTITUTION:The winding structure for a bobbin case 1 is disposed on one side of a magnet rotary shaft 5 and the connection terminals of coils 6, 7 are mounted on the opposite side. Consequently, the work for mounting the coils 6, 7 on the case 1 is simplified while suppressing the possibility of contact or interference with the terminals. Since a compact instrument having no stretching part is obtained, it can be employed as a miniature instrument in a liquid level indicator having a small dial. When a large dial is employed, a marginal space can be ensured on the back of the dial because the instrument has no stretching part. Even if other indicator is disposed proximately within the housing of the instrument, the electronic diver and the like can be arranged easily and the degree of freedom is enhanced in the layout.
