Abstract
The invention relates to an optical cable connector for device access and an optical installing and sealing component of the optical cable connector for device access. The optical cable installing and sealing component comprises a supporting cover and coordinating potions of mounting holes, wherein the supporting cover extends forward and backward in a radial direction, the coordinating portions of mounting holes are arranged in the periphery of the supporting cover, and the apertures of the coordinating portions of the mounting holes are smaller than the apertures of the corresponding mounting holes of the connector arranged on the panels of the device. Seal covers made of soft materials are sleeved on the coordinating portions through axial limiting structures, and one soft tooth capable of being transformed telescopically or a plurality of annular soft teeth capable of being transformed telescopically along an axial direction in intervals is/are arranged integrally on the seal cover. During the process that the soft teeth are merged from back to front into a corresponding mounting hole of the connector, the soft teeth are squeezed in a radial direction to deform by the cooperation of the supporting cover and the hole wall of the mounting hole of the corresponding connector, and fill a gap between the supporting cover and the mounting hole of the connector when the cooperating portions of the installing holes are completely merged in the installing holes of the connector, and therefore a seal is formed. The invention provides an optical installing and sealing component, wherein the optical installing and sealing component is simple in structure, low in cost, and can achieve fast sealing installation with a corresponding panel.
