Description
Technical field
The present invention relates to a kind of optical fiber annex, especially a kind of optical fiber quick connector.
Background technology
General and the supporting use of fiber-optical socket of optical fiber quick connector is to realize the quick grafting of optical fiber.Quick coupler is realized the butt joint of optical fiber through compressing the termination of two optical fiber.Usually; Article two, have one to be to be embedded in the tail optical fiber in the lock pin when dispatching from the factory in the optical fiber, another is the optical fiber that the user scene need be connected with tail optical fiber, and dock in the V-type groove termination of two optical fiber; Splash into high transparency liquid in the junction to improve translucidus; Then gland is covered on the V-type groove, through being shaped on the metal sleeve extruding gland of bayonet socket, optical fiber is pressed in the V-type groove again.
V-type groove in this type of quick coupler generally adopts plastic production; Because the hardness of working of plastics is lower than optical fiber, is very easy to scraped the plastics chip, thereby blocks the V-type groove or pollute the high light transmittance fluent meterial by sharp fiber end face; Logical optical property is affected, and causes the fiber alignment quality to descend.Secondly, when using metal sleeve extruding gland, need professional tool could it be promoted, thereby gland is applied extruding force, these professional tools carry comparatively inconvenience, and work brings unnecessary trouble to fibre junction.
Summary of the invention
The objective of the invention is to overcome the deficiency in the above-mentioned background technology; A kind of improvement of optical fiber quick connector is provided, and this optical fiber quick connector should be able to be realized the fast and stable butt joint of optical fiber, need not to use professional tool simultaneously; And have easy to use, characteristic of simple structure.
For realizing above purpose, the technical scheme below the present invention has adopted:
A kind of optical fiber quick connector; Comprise a lock pin barrel of tail stock; The left part of this lock pin barrel of tail stock is shaped on and is used to install the guide locating device provided cavity of fibre core; Right part is provided with the crust stationary installation that is used for fixing the optical fiber crust, and the middle part is shaped on the through hole that is communicated with said cavity and crust stationary installation, it is characterized in that:
Said fibre core is guide locating device provided to be comprised with lower component: be installed in the said cavity and the middle part be shaped on pickup groove the lock pin tailstock, be installed in fibre core tailstock left end pre-buried the lock pin of tail optical fiber, be installed in the derby that is used for said tail optical fiber of continued access and optical fiber in the said pickup groove, cover the briquetting of said derby upper surface, and be enclosed within the moving casing that is used to push said briquetting on the said lock pin tailstock; Offer on the lock pin barrel of tail stock of said briquetting top and be beneficial to the opening that promotes said moving casing; The upper surface of said derby is shaped on the V-type groove that is used to locate tail optical fiber and optical fiber, and the top of briquetting is shaped on the pretension rib towards raising; The right part of said lock pin tailstock is shaped on the fiber orientation hole that is communicated with said pickup groove; Be shaped on the stopping snap ring on the lock pin tailstock of fiber orientation hole right-hand member; This stopping snap ring passed through the right side that is stuck in through hole behind the through hole at lock pin barrel of tail stock middle part; Be shaped on the spring face on the lock pin tailstock in through hole left side, have a spring housing to be contained between this spring face and the through hole said lock pin tailstock is applied towards the jacking force on a left side;
Said crust stationary installation comprises by what three self-tightening claws formed at least enters fine hole; Separate through retraction slot between the adjacent self-tightening claw; All retraction slots stretch along the axis direction of lock pin barrel of tail stock; The inside surface of each self-tightening claw right-hand member is shaped on one group and is used for the promptly salient point of optical fiber crust, and outside surface is shaped on a boss; Be shaped on screw thread on the lock pin barrel of tail stock in self-tightening claw left side, have a nut gland to be tightened on this lock pin barrel of tail stock through screw thread, the right-hand member of this nut gland is shaped on into fine mouthful, and inwall is shaped on the conical surface that is used to push said boss so that the self-tightening claw shrinks.
The left part of said lock pin barrel of tail stock is set with a shell that is used for the said moving casing of cover cap.
The right-hand member in said fiber orientation hole is shaped on the one-level of taper and leads fine mouthful, and left end is shaped on secondary and leads fine mouthful; The two ends of the right-hand member of said V-type groove and the lower surface of said briquetting all are shaped on wedge shape and lead fine mouthful.
The two ends of the lower surface of said briquetting respectively are shaped on a bearing block.
Principle of work of the present invention is:
Be the work that conveniently continues; Said lock pin tailstock has been installed in the cavity of lock pin barrel of tail stock left part; Derby has been installed in the pickup groove of lock pin tailstock, and the part tail optical fiber that insertion core end face stretches out is placed in the V-type groove of derby, and briquetting is pressed in V-type groove top; Sleeve pipe is in the right side (not pushing to the pretension rib) of pretension rib, and the nut gland is not screwed; Can carry out following steps in regular turn in the time of need continuing:
1, through fiber stripping instrument peeling optical fibre crust (fixed length dimensioned);
2, the end face to optical fiber carries out pre-service (clean);
3, optical fiber is inserted for fine mouthful from advancing of nut gland, the light termination is led fine mouth, fiber orientation hole, secondary and is led fine mouthful, wedge shape and lead in the V-type groove of fine mouthful of entering derby through advance fine hole, one-level that the self-tightening claw forms in regular turn, docks with the end face of tail optical fiber;
4, the nut gland of screwing, the conical surface of nut gland inwall force the self-tightening claw to shrink, chucking optical fiber crust;
5, moving casing is pushed away left; The inwall of moving casing extruding pretension rib, because the lower surface of briquetting is provided with two bearing blocks, therefore the part between two bearing blocks can downwarping, the termination of pressed fiber and tail optical fiber, thereby fixed fiber;
6, shell is installed, operation is accomplished.
The invention has the beneficial effects as follows: among the present invention, the lock pin barrel of tail stock at moving casing place is shaped on opening, and operating personnel can compress fibre core directly with pointing its promotion, need not to carry other instruments, and operation is very easy, and work efficiency is higher; And among the present invention, described V-type groove is opened on the derby, and hardness is higher than the hardness of fibre core, and optical fiber is difficult for scratch V-type groove, avoids causing damage perhaps to pollute the liquid of high light transmittance to optical fiber.In addition, structure of the present invention is also comparatively simple, and cost of manufacture is lower.
