Description
Technical field
The utility model relates to the interface unit of a kind of fiber alignment time spent, is specifically related to the visual cold splice for optical fibers of a kind of environment-friendly type.
Background technology
Optical fiber has that bandwidth, loss are low, in light weight, antijamming capability strong and the characteristics of reliable working performance, is widely used in communication, Local Area Network at present, fields such as Fiber to the home (FTTH), high-quality video transmission, Fibre Optical Sensor, testing meter and instrument.At present optical fiber connects and generally adopts cold splice for optical fibers, the continuous son of this optical fiber have simple operation fast, link reliable, lower-cost characteristics, but and repetitive operation, cost performance higher.Simultaneously, it is uncharged using cold splice for optical fibers to connect optical fiber, also is widely used in the manufacturing environment such as petrochemical industry and petroleum refining, coal and other no open flames (or electric arc).
When conventional cold splice for optical fibers connects optical fiber, the naked fine joint of two optical fiber is inner compacted at continuous son, finish continuing of optical fiber, and the shell and the part of conventional cold splice for optical fibers generally adopt plastic production, so just produce a problem: when optical fiber connected, operating personnel can't see the butt joint situation of continuous son the inside two optical fiber, might misoperation cause fibre-optical splice wearing and tearing, dislocation, cause optical fiber to connect poor effect, influence the transmission of data.
The utility model content
The purpose of this utility model is the deficiency that will overcome the above-mentioned background technology, and the improvement of cold splice for optical fibers is provided, and this cold joint connector should have good connecting effect, optical fiber connects the visible characteristics of situation.
The purpose of this utility model is achieved through the following technical solutions:
The visual cold splice for optical fibers of environment-friendly type comprises that two ends all are shaped on the box-type shell of connection chamber, is provided with the hold-down mechanism that is used to compress two optical fiber in this box-type shell, respectively is positioned with a chuck that is used for fixing the optical fiber crust in the connection chamber at box-type shell two ends; One end of described chuck is positioned in the connection chamber, and the other end is shaped at least two elastic press, and pushes inside the contraction with the pressed fiber crust of tube wall that described elastic press makes chuck by an ejector sleeve; Described hold-down mechanism comprises the slider pad at box-type shell middle part, the both sides of slider pad are respectively caulking groove and build groove, other has a V-type groove derby to be inlaid in the caulking groove, also has one to build lid and be pressed into and build in the groove, pushes described slider pad and compresses fibre-optical splice in the V-type groove derby; It is characterized in that: described box-type shell, slider pad, block lid adopt transparent material to make.
Described transparent material is PVC.
Use principle of the present utility model is:
The optical fiber that two decorticatings are good inserts from the chuck at box-type shell two ends, promotes the ejector sleeve (ejector sleeve internal diameter and chuck external diameter adapt) on two chucks then, and the elastic press by on the extruding chuck radially shrinks chuck, thus the pressed fiber crust; To build lid then and be pressed in the block groove, block lid compressing slider pad compresses the fibre-optical splice in the V-type groove, thereby realizes fiber alignment.Because in the utility model, box-type shell, slider pad, block lid all adopt transparent material to make, operating personnel can see the butt joint situation of optical fiber, thereby operation is accurate more, fibre-optical splice wearing and tearing, problem of misalignment when having avoided the conventional fiber cold joint connector to connect, and it is more reliable to make that optical fiber connects.In addition, improvement of the present utility model is simple, and cost is not high yet.

Fig. 3 is a sectional structure synoptic diagram of building lid in the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, the visual cold splice for optical fibers of environment-friendly type, comprise that two ends all are shaped on the box-type shell 1 of connection chamber, be provided with the hold-down mechanism that is used to compress two optical fiber in this box-type shell, respectively be positioned with a chuck 4 that is used for fixing the optical fiber crust in the connection chamber at box-type shell two ends.
One end of described chuck is positioned in the described connection chamber, the peripheral outer wall of the other end is shaped at least two elastic press 4-1, and by the described elastic press of an ejector sleeve 5 extruding the tube wall of chuck is inwardly shunk (to be shaped on cavity in the chuck with the pressed fiber crust, optical fiber inserts this cavity, conventional structure is not done detailed description); Described hold-down mechanism comprises the slider pad 2-3 at box-type shell middle part, and the both sides of slider pad are respectively caulking groove 1-1 and build groove 1-2, and other has one can the V-type groove derby 2 of fibre core location be inlaid in the described caulking groove; Have a block to cover 3 and be pressed in the described block groove, at this moment, the block lid can push described slider pad and compress, thereby two fibre-optical splices that compress in the V-type groove derby are realized continuing of optical fiber.These all are prior aries, and use principle is not described in detail.
For making operating personnel can be clear that the butt joint situation of two optical fiber when connecting optical fiber, the utility model adopts transparent material to make (as PVC) on aforementioned box-type shell, slider pad, block lid.Make like this operating personnel docking operation more accurately, fibre-optical splice wearing and tearing, problem of misalignment when having avoided the conventional fiber cold joint connector to connect, it is more reliable to make that optical fiber connects.
