Summary of the invention
The utility model technical matters to be solved provides a kind of fiber adapter.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of fiber adapter; It is characterized in that: comprise housing; And the axially extending bore that is positioned at housing; The centre of said axially extending bore be equipped with and the side face of this axially extending bore between the passage that has the gap and extend in the same way with this axially extending bore; Said channel content is equipped with the sleeve that extends in the same way with this axially extending bore, and the size of said axially extending bore and ambient light fiber connector is complementary, and the size of the ceramic insertion core of the size of said sleeve and ambient light fiber connector is complementary.
Said passage and this housing are through being connected with the vertical outstanding connecting portion of this axially extending bore, and said passage, housing and said connecting portion are one-body molded.
In order to prevent that sleeve from deviating from passage, the two ends of said passage have inwardly outstanding protruding circle.
Preferably, also be provided with the axially extended raised line that play the guiding role in the said axially extending bore.
In order to clamp the fiber adapter in the said through hole, the side of said housing has the shell fragment that is communicated with axially extending bore.
In order when not using, to protect this fiber adapter, the two ends of said housing to be inserted with the stopper that the shape with this axially extending bore and passage is complementary.
Can fill better and be positioned at passage in order to make this sleeve radially have elasticity, have one on the said sleeve along its axially extended strip breach.
Compared with prior art, the advantage of the utility model is this fiber adapter, and axially extending bore and passage are one-body molded; Sleeve inserts passage; Can change according to the size of the joints of optical fibre, not only simple in structure easy to process, and make the connection of fiber adapter reliable and stable.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-4, be the fiber adapter of the utility model, comprise housing 1, have in the said housing 1 along this housing 1 axially extended axially extending bore 2, the shape of this axially extending bore 2 can be complementary with the shape of the joints of optical fibre, is used to insert the joints of optical fibre.And has an axially extended passage 3 along this axially extending bore 2 in the centre of this axially extending bore 2; Has the gap between the side face of this passage 3 and axially extending bore 2 and through being connected with this housing 1 with these axially extending bore 2 vertical connecting portions 4; Be inserted with a sleeve 5 in this passage 3, this sleeve 5 is complementary with the shape and size of the front end ceramic insertion core of ambient light fiber connector.When the extraneous joints of optical fibre inserted, the shell of the joints of optical fibre just was complementary with axially extending bore 2 and is positioned at the axially extending bore 2 in passage 3 outsides then, and the ceramic insertion core of the head of the joints of optical fibre is inserted in this passage 3, realized the butt joint of two joints of optical fibre.Two joints of optical fibre are inserted at the two ends of the axially extending bore 2 of housing 1 respectively, and the ceramic insertion core of the joints of optical fibre just interconnects in this sleeve 5.The housing 1 of said fiber adapter and axially extending bore 2 and connecting portion 4 and passage 3 be integrated injection molding all; After making, sleeve 5 inserts this passage 3 again; Thus; When the size of the ceramic insertion core of the joints of optical fibre had change, the sleeve 5 that can make different size inserted then, has improved the usable range of this fiber adapter more.And in order to make sleeve 5 be full of this passage 3 better, have one on the said sleeve 5, make this sleeve 5 have elasticity diametrically along its axially extended strip breach.The diameter of sleeve 5 can be made into the diameter that is slightly larger than passage 3, utilizes the flexible fastening of sleeve 5 behind the joints of optical fibre insertion passage 3.
Preferably, like Fig. 1, shown in 3, the side of this housing 1 has shell fragment 11, and this shell fragment 11 directly is communicated with axially extending bore 2, and when making the joints of optical fibre insert, shell fragment 11 is the grip optical fibers connector from the outside, is beneficial to fastening in axially extending bore 2 of the joints of optical fibre.And in this axially extending bore 2, also be provided with axially extended raised line 12, this raised line 12 plays guide effect in the process of joints of optical fibre insertion axially extending bore 2.The two ends of this passage 3 have inwardly outstanding protruding circle 31, prevent that sleeve 5 from deviating from passage 3.
Housing 1 two ends of this fiber adapter also are inserted with stopper 6, and this stopper 6 is complementary with the shape of axially extending bore 2 and passage 3, protection passage and sleeve 5 when this fiber adapter does not use.
Like Fig. 5, shown in 6, be second embodiment of this fiber adapter, among this embodiment, be the fiber adapter of duplex, this adapter has two axially extending bores 2, has passage 3 and sleeve 5 in the axially extending bore 2 respectively.This fiber adapter can dock two groups of joints of optical fibre simultaneously.
Like Fig. 6, shown in 7, be the 3rd embodiment of this fiber adapter, among this embodiment; Fiber adapter for tetrad; Adapter has four axially extending bores 2, all has passage 3 and sleeve 5 in each axially extending bore 2, and this fiber adapter can connect four groups of joints of optical fibre simultaneously.
This fiber adapter, axially extending bore and passage are one-body molded, and sleeve inserts passage, can change according to the size of the joints of optical fibre, and is not only simple in structure easy to process, and makes the connection of the joints of optical fibre reliable and stable.
