Abstract

The utility model discloses an optical fiber connector, which comprises an embedded body, a shell and an elastic door. The elastic door is made of deformable plastic or rubber material and is clamped and fixed with the shell through the embedded body. When an optical fiber plug is inserted in to the optical fiber connector, the elastic door produces elastic deformation and turns over in the shell of the connector. After the optical fiber plug is drawn out of the optical fiber connector, the elastic door restores to the closed state according to the self elasticity so as to prevent the dust from entering the optical fiber connector and prevent the light produced by the optical fiber elements in the optical fiber connector from emitting out of the optical fiber connector.

Description

The joints of optical fibre

[technical field]

The utility model is about a kind of joints of optical fibre, particularly about a kind of joints of optical fibre with flexible door structure.

[background technology]

Along with fiber-optic signal transmits use growing, to the also constantly increase of demand of the joints of optical fibre, the joints of optical fibre adopt metal or ceramic contact pin fixed fiber usually, and this contact pin is installed in the metal shell to realize the butt joint of optical fiber.But these type of joints of optical fibre need accurate mechanical positioning, and structure is comparatively complicated.Because of such joints of optical fibre only are suitable for manual fitting, production cost is higher again, so be unfavorable for producing in batches.

Industry has been released a kind of joints of optical fibre simple in structure, and this kind joints of optical fibre use the plug and socket of plastic material, is mainly used in the consumption electronic products such as video, audio frequency or uses in the short distance optical fiber communication of fiber optic fibers, plastic.This kind joints of optical fibre can adopt the jetting formation process manufacturing, and need not metal cladding, so the utmost point is suitable for automated production and assembling.

But, be equiped with optical element usually in this kind fiber optic fibers, plastic connector, in order to produce light signal or induction light signal and light signal is converted to corresponding electric signal.This kind optical element needs good encapsulation usually, with the optical property that prevents that dust from entering influences optical element in the joints of optical fibre.And the optical element in being installed in connector is when producing light signal, also needs the connector inlet is carried out necessary sealing, and the optical signals connector that is produced to prevent directly penetrates, and operator's eyes are damaged.

Prior art adopts the dust plug structure to realize above-mentioned purpose more, when it does not dock with other optical device at the joints of optical fibre, dust plug is assemblied in the peristome of the joints of optical fibre, reaches sealing process.But it needs dust plug is extracted before inserting Optical fiber plug, again dust plug is inserted behind the drawn optical fiber plug again, and the plug of dust plug is extremely inconvenient, and need occupy certain space.Because of dust plug normally separates with the fiber optic fibers, plastic connector, when the fiber optic fibers, plastic plug inserts these joints of optical fibre, must place dust plug separately, thereby increase the difficulty of using and managing again in order to avoid lose.

The another prior art of fiber optic fibers, plastic connector such as Jap.P. spy open 2000-131564 number, and the fiber optic fibers, plastic connector body that it disclosed adopts door 10 shown in Figure 1.This door 10 is installed on fiber optic fibers, plastic connector body jack portion (figure does not show) front end, realizes closing function.This door 10 comprises a baffle plate 11, an elastic body 13 and one 15.Wherein, baffle plate 11 is established storage tank 111 with reception elastic body 13, but the block end 133 of draw-in groove 113 fixing elastic bodys 13, and through hole 115 is used for receiving axes 15.Penetrate the through hole 115 and elastic body 13 of baffle plate 11 when axle 15 after, this door 10 can be installed on fiber optic fibers, plastic connector body jack portion front end, and the elastic tip 131 by elastic body 13 is resisted against the fiber optic fibers, plastic connector body and produces elastic acting force, keeps the sealing of 10 pairs of fiber optic fibers, plastic connector bodies of door.

But this element of 10 comparatively separates, and it is difficult for assembling; And the elastic acting force that produces as elastic body 13 is strong excessively, then is difficult to keep the plumbness of door 10 and fiber optic fibers, plastic connector body jack portion, and then is difficult to the peristome of complete closed fiber optic fibers, plastic connector body.

[utility model content]

The purpose of this utility model is to provide a kind of joints of optical fibre of tool simple elasticity door, and this flexible door can rely on self elasticity to realize switch to joints of optical fibre peristome.

For realizing the utility model purpose, the joints of optical fibre of the present utility model comprise a housing, a flexible door and an embedded body.Flexible door is to be made by deformable plastic cement or elastomeric material, and this flexible door is clamped and fastened on housing by embedded body.When Optical fiber plug inserted these joints of optical fibre, flexible door produced elastic deformation and overturns in connector shell.Behind Optical fiber plug drawn optical fiber connector, flexible door, enters in the joints of optical fibre to prevent dust to closed state according to self recovery of elasticity, also can prevent the ejaculation of light that optical element produces in the joints of optical fibre simultaneously.

Compared to prior art, advantage simple in structure, that be easy to assemble that the flexible door of the utility model joints of optical fibre has.
