Abstract
The utility model discloses a collet for an optical fiber splice. The collet comprises a columnar main body which is provided with an optical fiber cable hole; at least two locking heads divided by a locking groove are arranged at one end of the main body; at least one press tongue is arranged at the other end of the columnar main body; the upper head face of the tongue body of the press tongue is an arc face which can stretch under press; and the arc face is higher than the outer surface of the columnar main body. Compared with prior art, the collet is characterized in that at least one press tongue is arranged at the front end of the columnar main body of the collet, the upper head face of the tongue body of the press tongue is an arc face which can stretch under press, and the arc face is higher than the outer surface of the columnar main body, so when installing, an optical fiber cable threads through the optical fiber cable hole and pushes an ejector tube of an optical fiber splice group, and when the ejector tube is pushed to the position of the press tongue, an arc face at the backside of the press tongue is pressed down. Since the tongue of the press tongue is closely attached to the surface of the optical fiber, and the arc face of the tongue body of the press tongue stretches under press to enable the optical fiber move forward automatically, thus ensuring powerful and reliable splicing of the fibers.
Description
Technical field
The utility model relates to a kind of optical fiber connector parts, especially a kind of optical fiber connector chuck.
Background technology
At present; the optical fiber cable that is used for the optical fiber connector product is installed the main specific purpose tool that uses; promote naked fibre by oppressing crooked optical fiber crust; thereby guarantee the applying of optical fiber surface, rely on the clamp device single-point that is arranged in the sleeve to clamp then, specific purpose tool can not guarantee the applying power that optical fiber is enough; more cannot say for sure to demonstrate,prove the real applying of fine face during the surperficial defectiveness of especially naked fibre; and can not effectively prevent the rotation of optical fiber cable, unexpected when stressed in installing or using, naked fibre can not adequately protect.A kind of chuck that is used for the connector of optical fiber is now also arranged, and is that the tapered screw face is set on the cylindrical locking head of chuck surface etc., though this structure dependable performance, anti-rotation automatically, complicated operation in handshaking procedure, the running time of continuing is long.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art; and provide a kind of in installation and use; the push-in stroke of control optical fiber; guarantee that fiber end face has enough applying power, the grip optical fibers crust guarantees the fiber alignment quality; prevent that optical fiber from rotating; effectively the protection optical fiber surface is intact, and can operate fast, is easy to the microminiaturized chuck that is used for optical fiber connector.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of chuck that is used for optical fiber connector, the cylindrical body that comprises a band optical fiber cable hole, end at cylindrical body is provided with at least 2 locking heads that are divided into by locking slot, the other end at described cylindrical body also is provided with at least one pressure tongue, but this upper surface of pressing the tongue body of tongue is the arcuate surface of pressurized elongation, and arcuate surface is above the cylindrical body outside surface.
Also be provided with a distortion groove on described cylindrical body, this distortion groove links to each other with locking head.
The outer end of described locking head also is provided with an afterbody, and described locking slot extends to this afterbody.
Described cylindrical body inside surface is provided with locking slot; Described locking slot is a ring groove.
Compared with prior art, the utlity model has following advantage:
1, the utility model chuck is established by at least one at the cylindrical body front end and is pressed tongue, but this upper surface of pressing the tongue body of tongue is the arcuate surface of pressurized elongation, and arcuate surface is above the cylindrical body outside surface, when installing, optical fiber cable passes the optical fiber cable hole, promote the ejector sleeve of fibre junction group, when ejector sleeve is advanced into pressure tongue position, press the back arcuate surface of tongue to be pressed down, be close to optical fiber surface owing to press the tongue tongue, press the arcuate surface pressurized elongation of tongue tongue body, optical fiber is pushed ahead automatically, thereby guarantee that fine face applying is strong, reliable.On the other hand, need not artificially interfere, be easy to realize the microminiaturization of total.
2, the pressure tongue of the utility model chuck front end is controlled the push-in stroke of optical fiber by the distortion size of decrement, tongue body arcuate surface, guarantees the enough applying power of optical fiber.
3, the utility model chuck is provided with the cylinder conical surface of locking slot in the cylindrical body rear end, when pushing away before ejector sleeve continues, ejector sleeve rear portion cylinder size has the cylinder conical surface of locking slot less than the collet body rear portion, makes its endoporus drawdown deformation, make inner fibre core stressed evenly, thus locking optical fiber crust.
4, the utility model chuck is in installation and use, and chuck is the grip optical fibers crust effectively, realizes the multiple protective of optical fiber.
5, the utility model chuck at first compresses the pressure tongue being held tightly in the process by the ejector sleeve propelling when pushing, then by compressing the cylinder conical surface of locking slot, locking optical fiber crust.
6, connect an afterbody in the rear end of cylindrical body, afterbody has good guide effect, is convenient to the insertion of optical fiber cable, also can hold the sleeve pipe that is used for different size optical fiber crust simultaneously, expands usable range.
7, processing in wearing the optical fiber cable process, prevents withdrawing from of optical fiber cable on the one hand at the locking slot of cylindrical body inside surface, in the process of locking, has also played good clamping and fixation.
Description of drawings
Fig. 1 is structural representation figure of the present utility model.
Fig. 2 is the cut-open view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, in conjunction with Fig. 2, comprise cylindrical body 1, at the front end of cylindrical body 1 for by single or be symmetrical in a plurality of pressure tongues 2 of axis, press the back 3 of tongue to exceed cylindrical body 1 surface, but the tongue body 4 of pressing tongue 2 is the arcuate surface 3 of pressurized elongation, and the length of the height of arcuate surface 3 and arcuate surface 3 is by how many calculating of the size and the amount of contraction of push-in stroke, and pressing the number of tongue 2 can be 1,2,3 or 4 according to physical condition or needs.
In the rear end of cylindrical body 1 is the cylinder conical surface, cut apart at least 2 locking heads 6 that form by locking slot 5, the external diameter tapering size of locking head 6 is calculated by the optical fiber coupling mechanism force, and the number of locking head 6 can be 2,3 or 4 according to physical condition or needs, at the center of cylindrical body 1 is optical fiber cable hole 10, and this optical fiber cable hole 10 is the optical fiber cable through hole.
Cylindrical body 1 front end presses the tongue 2 and the situation calculating of locking again according to elder generation's propelling optical fiber apart from length of the locking head 6 of the rear end cylinder conical surface.
For optical fiber cable is not withdrawed from when penetrating, can also locking slot 9 be set in the inboard of the cylinder body 1 of above improvement project, this locking slot 9 also can be the ring groove of processing at cylindrical body 1 inside surface, as shown in Figure 2.
