  • Patent number: 10274683
    Abstract: The present invention provides a spring bias that is particularly suited for use to preload a low profile ferrule of an optical connector. In accordance with the present invention, an axial preload is applied to a connector ferrule by a spring structure provided external of the connector. In one embodiment, spring structure is provided outside a plurality of optical fiber connectors, which provides axial preload of multiple ferrules. Each ferrule could be of the type that supports a plurality of optical fibers of a fiber cable. In one embodiment, the spring bias is effected by a planar flexure external of the connector. The ferrule is coupled to the planar flexure with its longitudinal axis through the center of the planar flexure.
