Abstract
The utility model provides an internal-rotation self-locking integral LC optical fiber connector, which comprises a plastic main-body part; a metal inserting bush, a ceramic inserting pin, a metal tail handle and a spring are arranged in the plastic main-body part. One end of the ceramic inserting pin is inserted into the front end of the metal tail handle, and the rear end of the metal tail handle is sleeved with the spring. The plastic main-body is an integral body, meanwhile, the inner wall at the rear end is provided with two opposite guide grooves, and two opposite shell walls are provided clamping holes; the metal inserting bush is provided with two lug bosses which are matched with the two clamping holes. The LC optical fiber connector can be used for single joint or double joint and enhances locking force; the drawing force of the LC optical fiber connector is four times or more that of the general LC optical fiber connector, and the side pulling force resistance and the overall strength can be comparable to that of the (SC, FC and ST) standard optical connector with the inserting core of 2.50mm.
Description
Technical field
The utility model relates to optical fiber communication, and field such as comprise telecommunications and data communication, Local Area Network, wide area network (WAN), device end, CATV (cable television), Fiber to the home relates in particular to and is applicable to the LC joints of optical fibre.
Background technology
Along with optical fiber connects the development that networks, the continuous increase of connector density on optical cable density and the fibre distribution frame, the joints of optical fibre progressively develop to miniaturization.The LC joints of optical fibre are one of the most frequently used both at home and abroad at present miniaturization connectors.LC joints of optical fibre main component (engineering plastics) commonly used at present is to be constituted by protheca and back cover two parts, and the projection of back cover band tapering pushes by external force in the square hole of protheca, adopts (RJ) breech lock mechanism to make.Constitute because main component is protheca and back cover two parts, pulling capacity and anti-side pulling force rate are relatively poor, and when reality was used, the protheca window divided easy to crack, influenced the optical property of the joints of optical fibre.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned defective, and a kind of inward turning self-locking integral L C joints of optical fibre are provided.
The purpose of this utility model can be achieved through the following technical solutions:
The inward turning self-locking integral L C joints of optical fibre comprise plastic body spare, are provided with metal sleeve, ceramic contact pin, metal caudal peduncle and spring in the plastic body spare.One end of ceramic contact pin inserts the front end of metal caudal peduncle, the rear end of metal caudal peduncle then is with spring, described plastic body spare is as a whole, the main component that has changed the former LC joints of optical fibre is by protheca and back cover structure dimerous, improved anti-side pulling power, the rear end inwall is provided with two relative gathering sills, is provided with hole clipping on two relative shell walls; Described metal sleeve is provided with two and matching used two boss of hole clipping.When assembling, after elder generation put into plastic body spare to metal caudal peduncle that is inserted with ceramic contact pin and spring etc., two boss with the metal sleeve inserted in the plastic body spare by gathering sill again, inserted the back that puts in place and rotated 45 degree, and boss enters hole clipping, auto lock.After the utility model was joined simply connected anticreep clamping ring spare, its overall dimensions were consistent with the common LC monomer joints of optical fibre; After joining the duplex clamping ring, can form the duplex LC joints of optical fibre easily.Its interface size conforms YD/T1272,1-2003 and IEC/PAS 61754-20 (2001) standard.
The utlity model has following characteristics:
1, adopt modularization, compact, anti-slip design, the LC product of its interface and standard is compatible.
2, connector body can be used for simply connected or two kinds of structures of duplex;
3, strengthened coupling mechanism force, its pulling capacity is more than four times of the common LC joints of optical fibre, and its anti-side pulling power and bulk strength can be connected with the standard fiber of (SC, the FC and ST) of 2.50mm lock pin and compare favourably.
