Description
Technical field
The present invention relates to fiber cabling device technique field, particularly to a kind of mechanical optical fiber connector。
Background technology
Along with the development of communication technology, optical fiber is widely used, and optical fiber splicer is also widely used among the continuing of optical fiber Cheng Duan。Optical fiber splicer is the device carrying out between optical fiber and optical fiber removably connecting, and it gets up the two of optical fiber end face precision docking, so that the light energy of launching fiber output can be coupled in reception optical fiber to greatest extent。
The optical fiber splicer occurred in the market is of a great variety, if Authorization Notice No. is that CN203396981U discloses " a kind of single-core fiber mechanical type pecker ", its structure is as shown in Figures 1 to 4, including the first housing 1 ', second housing 2 ' and " n " shape spring caps 6 ', described first housing 1 ' and the second housing 2 ' constitute body 3 ' by the pressing of " n " shape spring caps 6 ', the face that described first housing 1 ' is relative with the second housing 2 ' inner side is all correspondingly provided with wire casing 4 ', the width of the middle part of described wire casing 4 ' is more than the width of wire casing 4 ' two-end part, it is provided with shell fragment 5 ' in the wire casing 4 ' of described second housing 2 ', the outside of described first housing 1 ' and the second housing 2 ' is respectively equipped with projection 7 ', described " n " shape spring caps 6 ' is provided with the rotation hole corresponding with described projection 7 ', described " n " shape spring caps 6 ' is rotatedly connected with described first housing 1 ' and the second housing 2 ' by described rotation hole。Its operation principle is: during use, first optical fiber is placed in the wire casing 4 ' of the second housing 2 ', the connector portions of optical fiber is placed on the wide middle position of wire casing 4 ', control optical fiber by shell fragment 5 ' and enter the position at wire casing 4 ' middle part, after connecting until the optical fiber of continued access, the first housing 1 ' and the second housing 2 ' is made to cover connection, and the rotation hole of " n " shape spring caps 6 ' is stuck on projection 7 ', pressure " n " shape spring caps 6 ' can by optical fiber tightly be pressed together in body 3 ', it is achieved that the continued access of optical fiber。A kind of embodiment as above-mentioned optical fiber splicer, wire casing 4 ' the middle part of described second housing 2 ' is provided with sponge 21 ', the correspondence position of the wire casing 4 ' of described first housing 1 ' is provided with briquetting 11 ', when the first housing 1 ' and the second housing 2 ' pressing, pressure effect by briquetting 11 ' and sponge 21 ', ensure that the optical fiber firmness in connector portions, make joint not easily loose；As the another embodiment of above-mentioned optical fiber splicer, the middle part of the wire casing 4 ' of described second housing 2 ' is provided with connecting tube 22 ', can be played the effect fixing two optical fiber by connecting tube 22 '。
But, above-mentioned " a kind of single-core fiber mechanical type pecker " has the disadvantage that: first, arrange owing to the first housing 1 ', the second housing 2 ' and " n " shape spring caps 6 ' are split, firstly the need of making the first housing 1 ' and the second housing 2 ' snap together during installation, then press solidly again through " n " shape spring caps 6 ', cause location inconvenience, operate relatively complicated；Second, owing to adopting " n " shape spring caps 6 ' that the first housing 1 ', the second housing 2 ' are pressed solidly, it is easy to make that loosening phenomenon occurs between the first housing 1 ' and the second housing 2 ', cause that fixed effect is poor；3rd, although arranging sponge 21 ' to avoid, with briquetting 11 ', the problem that loosening occurs in optical fiber at the place of continuing, but when the first housing 1 ' and the second housing 2 ' can cause two optical fiber skew occur at joint when covering, cause that docking concentricity is relatively low；Connecting tube 22 ' is set and can guarantee that the concentricity of two fiber alignments, but easily occur at the place of continuing loosening, affect signal transmission。
