Abstract
The utility model discloses a communication optical fiber adapter which comprises a plastic housing with two connection ports, an inner core is arranged in the center of the plastic housing, and a sleeve is arranged in the inner core. The adapter is characterized in that a turnable end cap is fixed at at least one connection port. The utility model has the advantages that since the turnable end cap is fixed at the connection port, when one connection port of the adapter is inserted into a communication optical fiber connector and the other end is idle, the end cap can effectively isolate the adapter from the outside, and prevent dust entry. Meanwhile, infrared rays given out by the optical fiber are prevented from injuring optomeninx of people.
Description
Technical field
The utility model relates to a kind of telecommunication optical fiber adapter, relates in particular to a kind of telecommunication optical fiber adapter with dust cap.
Background technology
In the optical fiber telecommunications system process was installed, the connection of telecommunication optical fiber need be used the telecommunication optical fiber connector for convenience.The end of telecommunication optical fiber connector is provided with preceding lock pin, in the preceding lock pin telecommunication optical fiber is installed, and in order to make two telecommunication optical fiber butt joints between the telecommunication optical fiber connector, just need use the telecommunication optical fiber adapter.The telecommunication optical fiber adapter comprises a plastic casing, it has two input ports, and the centre of plastic casing is provided with inner core, and inner core has the right cylinder of a hollow, be provided with ceramic sleeve in the right cylinder of hollow, ceramic sleeve is used to insert the preceding lock pin of telecommunication optical fiber connector.Because the telecommunication optical fiber adapter than higher, before use, can be loaded onto dust cap to environmental requirement usually on two connectivity ports of telecommunication optical fiber adapter, prevent that external dust from entering.When actual use, need remove dust cap, expose the insertion of connectivity port for communications connector, insert a connectivity port of adapter when telecommunication optical fiber connector after, and another connectivity port is when idle.Insert the retina that infrared ray that the telecommunication optical fiber of that end sends can damage the people.Dust can enter from idle port simultaneously, influences the normal use of telecommunication optical fiber adapter.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of retina of avoiding damaging, and it prevents the telecommunication optical fiber adapter of the band dust cap that dust enters.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of telecommunication optical fiber adapter, comprise plastic casing, described plastic casing has two connectivity ports, be provided with inner core in the middle of the described plastic casing, in-core is provided with sleeve in described, is set with the end cap that can dig at least one connectivity port.
All be provided with the end cap that to dig on described two connectivity ports.
Described plastic casing side is provided with axle bed, described end cap comprises axis part and cover plate, described axis part is arranged on an end of cover plate, described axis part comprises rotating shaft, described rotating shaft is arranged in the described axle bed, be arranged with torsion spring in the described rotating shaft, an end of described torsion spring acts on the side of plastic casing, and the other end effect of described torsion spring on the cover board.
Described plastic casing comprises upper shell and the lower house that is fixed together, described inner core comprises last inner core and the following inner core that is fixed together, described upward inner core and following inner core are respectively arranged with the right cylinder of hollow, and described sleeve is arranged in the described right cylinder.
Described sleeve is a ceramic sleeve.
Described plastic casing is outside equipped with the fixedly jump ring of usefulness.
Compared with prior art, the utility model has the advantages that the connectivity port is provided with the end cap that can dig, after the telecommunication optical fiber connector is inserted in a connectivity port of adapter, when another connectivity port is idle, end cap can effectively completely cut off and extraneous contacting, and prevents that dust from entering.Avoid infrared ray that optical fiber sends retinal damage simultaneously to the people.
