Abstract

The utility model provides a waterproof sealing optical fiber connector, which comprises a stop piece, a cylindrical mounting part, a 0-shaped sealing ring, a spring, a mounting box and a shell, wherein a connecting flange and the spring are arranged on the outer peripheral surface of the mounting part, one end of the stop piece applies extrusion force to the spring in the direction of one side of the connecting flange, so that a connecting sheet on the spring extrudes the 0-shaped sealing ring to be attached to one side end surface of the connecting flange, the 0-shaped sealing ring is extruded by vertical acting force, the O-shaped sealing ring is deformed along the radial direction of the O-shaped sealing ring due to the extrusion of the end surface, the inner wall and the outer wall of the 0-shaped sealing ring are more tightly attached to the outer peripheral surface of an optical fiber and the inner wall of the mounting box, gaps are prevented from being generated between the O-shaped sealing ring and the optical fiber and the mounting box, and the 0-shaped sealing ring can be tightly attached to the side end surface of the connecting flange, therefore, external rainwater is difficult to flow into the indoor side through the optical fiber, and a good waterproof sealing effect is achieved.

Description

Waterproof sealing's fiber connector Technical Field The utility model relates to the technical field of optical fiber equipment, in particular to a waterproof sealing optical fiber connector. Background The optical fiber connector is a detachable device for realizing rapid and accurate butt joint between optical fibers and is widely applied to optical communication systems. Through precise structural design, the optical signal transmission device ensures high-efficiency transmission between optical fibers, and has the characteristics of repeatable plug and low loss. In general, an optical cable is installed in a building such as a public house or a building, and can transmit a communication optical signal into the building. If the cable is to be laid into an aged or finished building, the interior design of the building needs to be changed, for which purpose it is necessary to drill holes in the outer walls of the building again in order to introduce the cable into the interior of the building. In order to prevent the damage of the optical fiber during the introduction of the optical fiber, an optical fiber connector is installed at the joint of the optical fiber, and since the externally introduced optical fiber is located at the outdoor portion, it is necessary to waterproof the external optical fiber in order to prevent external rainwater from flowing along the optical fiber to the indoor optical fiber connection apparatus.
