Thus the two housings are permanently joined together.
Description
The present invention relates to a kind of optical connector, specifically, relate to a kind of being installed in and be used to connect 32 hearts or more multiple fiber cable connector ferrule and a kind of method of optical fiber being inserted cuff of multiple fiber cable in the optical connector.
In general, the resistance because optical fiber is not communicated by letter, thereby can be used for transmission signals and be widely used in the communications field.A communication network that is made of optical fiber needs to connect optical fiber in some cases.The bifurcated of optical fiber or method of attachment comprise that mechanical connection is connected two kinds of technology with fusion.When mechanical connection, be in contact with one another and two mechanical fiber optics are coupled together by the end that makes two optical fiber.Fusing connects the end fusing to be made two optical fiber is connected with each other, and mechanical connection is different with it, owing to do not need to use electric energy and also finish easily outdoor, thereby be widely adopted.Common MACHINERY JOINT has been adopted in the connection of monofiber cable fully, recently, also begins to adopt MACHINERY JOINT in the connection of banded multiple fiber cable, thereby one group of optical fiber is coupled together simultaneously.For this reason, the connector that is used to connect multiple fiber cable is equipped with a cuff in its end, so that the alignment of the end of each root optical fiber.Cuff is divided into holocentric cuff and oversensitive cuff.Shown in Fig. 2 a, a micropore 2 is arranged on the holocentric cuff 1, optical fiber 4 can be guided to the outside from the inside of cuff 4 by this micropore 2.Then, the outside surface of two cuffs 1 that the optical fiber connector on each cuff all exposes is closely contact mutually, thereby realizes the connection of optical fiber 4.
Proposed a kind of common oversensitive cuff 1 among the korean patent application No.92-8065 (publication number No.96-13800), shown in Fig. 1 and Fig. 2 b, 4 or 8 micropores 2 have been arranged in the oversensitive cuff 1, can insert 4 or 8 optical fiber 4 by these micropores 2.Then, the outside surface of two cuffs 1 that the optical fiber connector on each cuff all exposes is closely contact mutually, thereby realizes the connection of optical fiber 4.Simultaneously, the micropore 2 that inside has penetrated on the common oversensitive cuff of multifiber should be processed very accurately, so that insert the optical fiber that diameter is about 125 μ m.Also comprise a guide rail 5 on the common oversensitive cuff, the guide rail 5 that is used for guiding fiber 4 is positioned at cuff inside and coaxial with each micropore 2.One group of semicircle guide groove 5a is arranged on the guide rail 5, and the diameter of guide groove 5a is between 125 μ m to 126 μ m.Yet,,, also be difficult to 8 optical fiber in the optical fiber ribbon cable are inserted in each micropore 2 simultaneously even the help of guide rail 5 is arranged for common oversensitive cuff 1.That is to say, be difficult to each optical fiber 4 is placed in the guide rail 5 that this is because cuff inside is very little and narrow, and little guide groove 5a of cuff can not clearly distinguish from the outside.In addition, be difficult to each optical fiber 4 is aimed at each guide groove 5a, and the end of each optical fiber 4 might be crooked when inserting the micropore 2 of cuff 1 vertically.
Simultaneously, along with extensively and fast popularizing of optical fiber communication, there is increasing communication network to set up recently.Therefore need improved optical connector, have in a large number, for example 32 or the optical cable of multifiber more with connection.
Therefore, the present invention is devoted to a kind of multiple fiber cable connector ferrule and a kind of optical fiber is inserted the method for this cuff, to get rid of one or more problem of the prior art, restriction and shortcoming basically.
An object of the present invention is to provide a kind of multiple fiber cable connector ferrule, this cuff is installed in the connector end, can connect a plurality of optical fiber connectors easily simultaneously by this cuff.
Another object of the present invention provides a kind of insertion method, and this method can be inserted the multiple fiber cable that has a plurality of optical fiber connectors in the cuff easily simultaneously.
Supplementary features of the present invention and advantage will point out in the following description that wherein a part can learn that a part can be found out from embodiments of the invention from explanation.The structure of pointing out in instructions, claims and accompanying drawing can make purpose of the present invention and other advantage realize and reach.
