JPS6429728A - Inspection instrument for sliding of connector for optical cable - Google Patents

Abstract

PURPOSE:To detect whether a spring itself of a connector is abnormal or not, and whether the spring is installed or not, etc., by providing two springs whose elastic modulus is different from that of the spring of the connector, and measuring a relative displacement of these springs. CONSTITUTION:By a fluctuation velocity driving device 30, a supporting arm is brought to an up-and-down motion, and a small spring 11 and a large spring 12 are transferred to a connector driving device 10 provided on the inside and the outside of a hollow cylindrical body 13. Subsequently, when the up-and-down motion of the supporting arm 20 is repeated plural times between the lowest descent position and a position level corresponding to a clamp position by a chuck 18, the up-and-down motion is executed, while generating a relative displacement against the chuck 18, namely, the supporting arm 20 of a coupling holder in accordance therewith. This relative displacement is transferred through a rod 15' to a relative displacement measuring instrument 40 for moving by interlocking with the supporting arm 20, and measured and recorded. Next, by comparing a pattern of the relative displacement quantity of a connector to be inspected, with a reference value which is measured, based on the connector at the time of a normal operation as a reference, the constitution of the connector, and whether the action is abnormal or not can be discriminated.
