Abstract: A coaxial connector to be connected to a mating connector includes a fixed assembly body and a movable assembly body connected to the fixed assembly body along an axial direction. The fixed assembly body includes a fixed side inner conductive body; a holding member for holding the movable assembly body; a fixed side insulation member for insulating between the fixed side inner conductive body and the holding member; and a first urging member for using the movable assembly body. The movable assembly body includes a movable side inner conductive body; a movable side outer conductive body; and a movable side insulation member. The movable side inner conductive body includes a first relay terminal having a retaining portion, a second relay terminal having a contact portion retained in the retaining portion, and a second urging member for urging the second relay terminal toward the fixed side inner conductive body.

Abstract: A method and system for managing parts can reduce the delivery time of the parts for fluid machinery such as pumps and can reduce the cost of stocking spare parts for the fluid machinery. The method comprises creating a compatible-parts database for a plurality of fluid machinery of a user in association with a common part used therein. The compatible-parts database identifying a part with a part identifier uniquely predetermined for the part. The method further comprises presenting the compatible-parts database to the user, and ordering a part for fluid machinery from a service provider by referring to the compatible-parts database.
