Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
This fiber adapter, as Figure 1-5, comprises housing 1, and at least two through holes that are axially parallel to each other 2 that are positioned at housing 1, as shown in the figure, this through hole 2 is two, this through hole 2 matches with the size of the joints of optical fibre, and two ends are used for inserting the joints of optical fibre.In described through hole 2, be provided with one and described through hole 2 axially extend in the same way and and the inside surface of through hole 2 between the spaced first passage 3 of tool, described first passage 3 with housing 1 one-body molded and with the inside surface of through hole separately, and be connected with the inside surface of through hole 2 by connecting portion 11.
Described fiber adapter also comprises the second channel 4 matching with described first passage 3, as shown in Fig. 2,4,5, described second channel 4 comprises the tube 41 of the hollow that internal diameter is identical with the internal diameter of first passage 3, and be positioned at tube 41 one end and axial vertical outward extending flange face 42 tube 41, the external diameter of described tube 41 is less than the through hole in housing 1, described second channel 4 can from one end of housing 1 insert with described first passage 3 mutually docking and together with form a passage inserting for sleeve 5.
And the length of described first passage 3 and second channel 4 and matching with the length of described sleeve 5.Preferably, the inner side, one end that described second channel 4 is relative with described flange face 42 is provided with inwardly outstanding flange collar 43, the position of inserting second channel 4 to limit described sleeve 5.
As Figure 1-5, between two second channels 4 in this embodiment, by link 7, interconnect, this link 7 comprises and flange face 42 brace orthogonal and that extend in the same way with second channel 4 between two second channels 4 of described second channel 4, the top of this brace is provided with the fixture block 71 to upper process, and simultaneously, between through hole 2 in this housing 1, be provided with and this link, it is the interface channel 12 that brace matches, the corresponding housing 1 of this interface channel 12 is provided with the groove 13 matching with described fixture block 71, when inserting corresponding through hole 2 by the connected second channel 4 of link 7 from one end of housing 1 for two, described link 7 inserts interface channel 12, and mutually engage with groove 13 by fixture block 71, link 7 and second channel 4 are all fixed in housing 1 to be docked mutually respectively at first passage 3.
During installation, can first sleeve 5 be put into respectively to two second channels 4 that connect by link, a part for sleeve 5 is positioned at second channel 4 another part and stretches out in one end that second channel 4 has flange face 42, along with second channel 4 and link insert housing, this sleeve 5 stretches out in the part of second channel 4 and can insert in first passage 3.Like this sleeve 5 can easily insert in housing 1 and with axially the extending in the same way of housing 1, when using, only the ceramic insertion core of joints of optical fibre end need to be inserted in the sleeve 5 in this housing 1 from two ends respectively, can realize the docking of the optical fiber at two ends, the internal diameter of described sleeve 5 and the ceramic insertion core of the joints of optical fibre match.Traditional fiber adapter is that housing 1 and passage are all divided into two, after inserting sleeve 5, housing 1 and the passage on both sides mutually dock and connect by welding, so both increased difficulty of processing, and easily damage at fusion process middle sleeve 5, reduced yield rate, and this fiber adapter of the application becomes the passage that inserts sleeve 5 two parts of the docking that cooperatively interacts, not only reduced the one-body molded needed difficulty of processing of this passage, and guaranteeing sleeve 5 assemblings accurately, can not use welding processing, also the damage of having avoided sleeve to cause because of welding.Preferably, the connecting portion 11 that described first passage 3 is connected with axial passage 2 is positioned at one end of described first passage 3, and axial vertical with described through hole 2, when the described through hole 2 of described second channel 4 insertion is interior, the flange face 42 of described second channel 4 one end is bonded to each other with described connecting portion 11, described second channel 4 is more prone to during fabrication, and when assembling is more prone to location.
And no time, the two ends of the housing 1 of this fiber adapter can be inserted respectively stopper 6 and be guaranteed that sleeve 5 in fiber adapter is not by contamination by dust.
As shown in Fig. 6-8, fiber adapter for the second embodiment of the present utility model, different from the first embodiment is, in the housing 1 ' of this fiber adapter, be provided with four through holes 2 ' that are parallel to each other, corresponding, adjacent second channel 4 ' is connected between two by two links 7 ' respectively between two, link 7 ' is provided with outstanding buckle 71 ' towards the face of housing 1 ', in housing 1 ', be provided with the interface channel 12 ' corresponding with this link 7 ', and the housing 1 ' of interface channel 12 ' is provided with the groove 13 ' corresponding with this buckle 71 '.And those skilled in the art also can recognize, the setting position of this buckle and groove also can exchange, and groove can be set on link, and buckle is set on housing.So long as can mutually engage the parts of location.And, when this fiber adapter has a plurality of parallel through hole, namely when thering is a plurality of first passages and second channel, at least that two adjacent second channels are connected by link, for example four second channels in the present embodiment are connected between two, also can be that four second channels are all connected by link, be that at least two of a plurality of second channels are interconnected to form a global facility, by link and housing, mutually locate, and second channel and sleeve are all accurately positioned in housing.So not only processing is simple, and assembly and disassembly is all very convenient, has also guaranteed the accuracy of fiber alignment simultaneously.Same, the two ends of the housing 1 ' of this fiber adapter can be inserted respectively stopper 6 ' and be guaranteed that sleeve 5 ' in fiber adapter is not by contamination by dust.
This fiber adapter, not only simple in structure, process and assemble is convenient, can also avoid thermal welding operation, has so both simplified the operation of assembling, and has more prevented the housing that causes because of welding and the damage of sleeve, has greatly improved yield rate.And this structure, can guarantee the accurate aligning of optical fiber, connect reliable.
Although more than described preferred embodiment of the present utility model in detail, should be expressly understood that, for a person skilled in the art, the utility model can have various modifications and variations.All any modifications of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
