Abstract
The utility model provides a fiber connector, consisting of a shell which is provided with an opening an accommodating space to accommodate fiber plugs, an optical semiconductor terminal arranged at the back-end of the shell, and a baffle with a sliding groove. The baffle has a sliding body and a shaft, wherein the sliding body is installed at and covering the opening through the shaft. Before inserted into the socket, a fiber plug is accommodated in the accommodating space by the rotating and sliding of the baffle. After the fiber plug is pulled out, the baffle covers the opening in the way of sliding and rotating to prevent the scrape to the transmission interface of plastic fiber and the loss of optical signals due to the plug pushing the baffle structure.
Description
[technical field]
The utility model is a kind of joints of optical fibre, particularly about a kind of joints of optical fibre with slide damper structure.
[background technology]
Use growingly along with Optical Fiber Transmission, the demand of the joints of optical fibre is constantly increased.The joints of optical fibre adopt metal or ceramic contact pin fixed fiber usually, and this contact pin is installed in the betal can to realize the butt joint of optical fiber.But these type of joints of optical fibre need accurate mechanical positioning, thus complex structure.Again, because of such joints of optical fibre only are suitable for adopting manual fitting, so be unfavorable for producing in batches, production cost is higher.
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, and it is mainly used in the consumption electronic products such as video, audio frequency or uses in the short distance optical-fibre communications of fiber optic fibers, plastic.The manufacturing of this kind joints of optical fibre can be adopted jetting formation process, and need not metal cladding, so the utmost point is suitable for automated production and assembling.
The existing design of fiber optic fibers, plastic connector is shown in Japanese patent laid-open 6-331859 case, referring to Fig. 1, the fiber optic fibers, plastic connector that it discloses comprises that a housing 1 has the jack 12 of accommodating an Optical fiber plug 2, rear end, the baffle plate 13 free to rotate that an optical semiconductor 11 is arranged at this housing 1 is arranged at this jack 12 the place aheads, and an optical fiber 21 is fixedly set in the Optical fiber plug 2.Before Optical fiber plug 2 inserted jack 12, this baffle plate 13 turned to the top of jack 12 so that the insertion of plug 2; After plug 2 is extracted from jack 12, this baffle plate 13 by rotate can inaccessible again jack 12 to realize the dustproof function.But, because of the baffle arrangement in the prior art is exposed to outside the housing, is very easily touched and cause damage, and this baffle arrangement being unsuitable for again replacing, baffle arrangement damages and will cause the discarded of fiber optic fibers, plastic connector.Again, because Optical fiber plug 2 is when inserting jacks 12, this baffle arrangement is exposed to outside the housing, will occupy certain space, thereby increases installing space.
Another design of fiber optic fibers, plastic connector is opened shown in the 2001-201663 case as the Jap.P. spy, and it adopts an elastic body to connect baffle plate and housing.When inserting plug, plug backs down baffle plate; When plug was pulled out, baffle plate resetted under the elastic body effect.But the prior art adopts plug to back down the structure of baffle plate, easily causes the wearing and tearing of plug, thereby increases the interface loss of Optical Fiber Transmission.
In addition, the fiber optic fibers, plastic connector also can adopt the dust plug structure to realize the dustproof purpose, before inserting plug dust plug is extracted, and after pulling the plug out of the socket dust plug is inserted.But the plug of dust plug is extremely inconvenient, and dust plug need occupy certain space, thereby needs bigger installing space.Again, dust plug separates with the fiber optic fibers, plastic connector usually, when the fiber optic fibers, plastic plug inserts this connector, must place dust plug separately in order to avoid lose, thereby increase the difficulty of using and managing.
[summary of the invention]
The purpose of this utility model is to provide a kind of joints of optical fibre, this kind joints of optical fibre have the slide damper structure, can avoid injuring the light signal generating loss because of plug pushing tow baffle arrangement causes the fiber optic fibers, plastic transport interface to scrape, its baffle plate is housed in the housing, thereby reduces installing space.
For realizing the utility model purpose, the joints of optical fibre that the utility model discloses comprise a housing, and this housing is provided with the receiving space that a peristome and is used for the up-winding fiber plug; One photosemiconductor terminal is arranged at the baffle plate that this housing rear end and one has a sliding tray, and this baffle plate has a slide mass and one.Wherein, this slide mass is by this axle installing and covering peristome.Before an Optical fiber plug inserted this socket, this baffle plate was contained in this receiving space by the method for rotating, slide; After this Optical fiber plug was extracted, this baffle plate then blocked this peristome by the method for sliding, rotate.
Compared with prior art, because of baffle plate can be contained in the peristome, so can reduce to install required space.Again, it adopts baffle plate to rotate the method for sliding in the back, can avoid the transport interface loss that is caused because of plug pushing tow baffle arrangement.
