Description
Technical field
The utility model relates to a kind of connector, especially relates to a kind of novel optical fiber quick coupler.
Background technology
Optical fiber quick connector is one of optical passive component of the fiber optic communication field most critical of realizing that Fiber to the home (FTTH), the external optical fiber quick connector that adopts is pre-buried optical fiber type structure at present, so-called pre-buried optical fiber type structure is meant at the pre-buried one section optical fiber of device inside, and this optical fiber front end grinding and polishing, the rear end is by V-type groove and the fiber alignment that will be connected, for reducing junction loss, fill optical fiber coupling cream in the V-type of the being everlasting groove.During engineering construction, the special-purpose construction tool that must adopt the product development merchant to provide just can be finished installation.
Yet adopt this structure but to have following defective: 1, since the docking point of optical fiber in the V-type groove, when construction, optical fiber is after the fiber cut cutter cuts off, end face is not checked (working-yard also can't be checked), so the dependence to fiber end face cut quality and optical fiber coupling cream is big, if cutting is bad, will directly influence the optical fiber junction loss, so its structural design is unreasonable; 2, in order to improve the fiber alignment precision, generally also need to adopt the V-type groove that the bare fibre of 0.125mm is positioned clamping, because the V-type groove adopts the organic material manufacturing, after the burn-in effects that is subjected to temperature variation and organic material, its holding force will reduce, junction loss will increase, and when therefore adopting this optical fiber quick connector, the reliability of its fiber gripper is relatively poor; 3, when mounted, because the fiber alignment place does not have the power that axially is adjacent to, the influence of V-type groove inner fiber coupling cream in addition, therefore tend to cause two fiber end face gaps greater than 0.005mm, though the use initial stage its insert loss and also can reach≤0.5dB, As time goes on, add the open architecture of V-type groove, the optical fiber coupling cream that is contained in V-type groove inside just can run off, contaminated and aging, and then can cause inserting loss and become big even blackout, so its less stable that continues; 4, because this optical fiber quick connector contains 2 fiber alignment points, so junction loss is actually the stack of two docking point losses, and it is bigger that it inserts loss; 5, when reality is used, fiber axis is to usually being subjected to pulling force, and pulling force directly acts on the ceramic contact pin of connector, thereby can have a strong impact on the fiber alignment effect, causes loss of signal to strengthen even interrupts; 6, the existing fiber quick coupler is owing to the manufacturing process complexity, and price is higher, and the special-purpose construction tool that must adopt the product development merchant to provide just can be finished installation in addition, has therefore limited the whole world enforcement that Fiber to the home (FTTH) greatly; 7, the existing fiber quick coupler must be by the process professional training, the skilled personnel that construct use specific purpose tool just can finish installation and maintenance, and user (user) can't carry out installation and maintenance, in case line fault occurs, only remain to be repaiied, so installation and maintenance is very inconvenient, existing in addition optical fiber quick connector non-fiber guiding mechanism on its structure, installation accuracy requirement to optical fiber is very high, must rely on special tooling, and installation rate is generally all more than 100 seconds.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of novel optical fiber quick coupler is provided, this connector is installation qualification rate height not only, reliability and stability are high, the insertion loss is less, cost of manufacture is lower, installation and maintenance are simple, that continues is stable very good, long service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel optical fiber quick coupler, main by the tailstock that is provided with through hole, the clamping bar formation that is installed in the ceramic contact pin of an end in the through hole and is installed in the other end in the through hole, ceramic contact pin inside is provided with positioning through hole, clamping bar inside is provided with guide through hole, and the axis of positioning through hole and the axis of guide through hole are on same straight line, also comprise and be arranged on the draw-in groove on the tailstock sidewall and be arranged in the draw-in groove and the cutting ferrule that can in draw-in groove, move up and down, the bottom of described draw-in groove is communicated with through hole in the tailstock, described clamping bar sidewall is provided with and clamps seam, and the bottom that clamps seam is communicated with guide through hole.
Described cutting ferrule is made of the card of thickness and draw-in groove coupling, and the side of card is provided with the groove with clamping bar external diameter coupling.
Described cutting ferrule is vertical with clamping bar to be provided with.
Described cutting ferrule is made by resilient material.
Described clamping bar is made by metal material.
Described clamping bar constitutes hydraucone away from an end end face indent of ceramic contact pin.
In sum, the beneficial effects of the utility model are: this connector is installation qualification rate height not only, and reliability and stability are high, and the insertion loss is less, cost of manufacture is lower, installation and maintenance are simple, and that continues is stable very good, long service life.
