Provided is a current measuring device such that it is possible to reliably keep the fluctuation range for the ratio error in output to within a range of ±0.5% and such that assembly thereof can be simplified. The current measuring device is configured to include at least a light entrance and exit, an optical fiber for a sensor, a Faraday rotator, a first 1/4 wavelength plate, a second 1/4 wavelength plate, a polarization separator, a light source, and a signal processing circuit comprising a photoelectric conversion element. The optical fiber for a sensor has birefringence and comprises one end into which two circularly polarized light beams having different directions of rotation enter and another end that reflects the circularly polarized light beams that have entered. In addition, the phase difference of two linearly polarized light beams in the round-trip light path between the two 1/4 wavelength plates is compensated, and the Faraday rotational angle when the Faraday rotator is magnetically saturated is set to 22.5°+a° so that the fluctuation range for the ratio error in the measured value of the current to be measured is set to be in the range of ±0.5%. In addition, the crystal axes on the optical faces of the two 1/4 wavelength plates are set to be perpendicular or are set to be in the same direction.

Optical fibre birefringence compensation mirror and current sensor
Disclosed is an optical fiber birefringence compensation mirror. Also disclosed is a current sensor wherein vibration resistance has been increased due to the optical connection of the optical fiber birefringence compensation mirror. The optical fiber birefringence compensation mirror includes: an optical fiber, a birefringence element, a lens, a magnet, a Faraday rotator, and a mirror. From the light incidence/emission end surface of the optical fiber, the birefringence element, Faraday rotator, and mirror are arranged in said order. Light comes in from the optical fiber, and is separated into two linearly polarised lights by the birefringence element. The polarisation planes of the two linearly polarised lights are rotated by the Faraday rotator, and the two linearly polarised lights are point-symmetrically reflected at one point by the mirror, then again rotated by the Faraday rotator, then re-combined into one light by the birefringence element and made to enter the optical fiber.

Housing for optical connector and optical connector
An optical connector is provided to reliably hold a ferrule assembly in a housing to enable it stable optical connection. The optical connector is able to accomplish stable connection without any concern of displacement of an optical connecting end portion of the ferrule, even if the optical connector is subjected to repeated connecting and disconnecting operations. In the optical connector, a ferrule assemble having a polygonal prism-shaped flange is accommodated and held so as to elastically reciprocate in a housing of a cavity which has a polygonal engaging portion to receive and engage the flange of the ferrule assemble. A protrusion is formed at an end part of each engaging wall in the direction of inserting the ferrule assemble to rise toward an insertion opening for the ferrule assemble, and each protruding portion of the protrusion is provided to have each different rising height thereof.
Provided is an electric current measuring instrument wherein compensation for the ratio error versus temperature characteristics of optical fibers and Faraday rotators for a sensor can be made by an optical system of an electric current instrument and wherein the fluctuation range of ratio errors in outputs can be brought within a range of ~0. 5%. The fluctuation range of ratio errors in measured values of electric currents outputted by a signal processing circuit is set within a range of ~0. 5% over a temperature range of -20°C or more to 80°C or less by means of the following: An electric measuring instrument is constructed in such a way as to include a signal processing circuit equipped with at least a polarized light separating unit, Faraday rotators, a light source, a photoelectric conversion element, and optical fibers for a sensor. The optical fibers for the sensor are placed around the periphery of an electrical conductor through which electric current to be measured flows. Furthermore, the rotation angle of each Faraday rotator at the time when the magnetism of each Faraday rotator is saturated is set to 22.5° + .alpha.° at a temperature of 23°C, thereby changing the rotation angle of each Faraday rotator by .alpha.° from 22.5°.
