Abstract: PURPOSE:To achieve a highly accurate measurement stably by winding an optical fiber for sensor around a conductor for a specified number of times at a position of a grounding potential side which is away from the conductor by an insulation distance and then making connection to a light transmission/reception part with the optical fiber directly. CONSTITUTION:A cylindrical ground shield 20 is placed concentrically fully away from a conductor 2V and insulation. A magnetic field sensor 21 is constituted so that an optical fiber is wound at an outer periphery of the shield 20 for a specified number of times, its winding start and winding end pass through a hole 10, and it is directly connected to a light reception/transmission part 12 which is fixed to a support container 6.

Filed: 1993-12-27
Abstract: PURPOSE:To provide a ferrule connector which has toughness and has an excellent sliding characteristic and dimensional stability under high humidity and is capable of maintaining a low connection loss over a long period of time by forming this connector of a resin compsn. formed by packing a specific ratio of carbon particulates into a polyphenylene sulfide resin and an optical switch. CONSTITUTION:This ferrule 1 consists of the resin compsn. formed by packing 100 to 150 pts.wt. carbon particulates into l00 pts.wt. polyphenylene sulfide resin. The molding shrinkage rate of the carbon particulates is high and the dimensional stability thereof is poor if the packing rate of these particulates is <=100 pts.wt. On the other hand, the viscosity at the time of melting of the resin increases and the molding of the precise ferrule l is difficult if the ratio is >=150 pts.wt. The more adequate carbon particulates are obtd. by carbonizing and calcining granular and powdery phenolic resins methanol solubility of <=20% at 650 to 1500 deg.C in a nonoxidizing atmosphere. The ferrule l characterized by the high strength and the low connection loss is produced by packing such carbon particulates into the resin.
