Description

A kind of dust cap docking facilities of optical fiber connector

Technical field

The utility model is related to optical dust-proof cap field, the dust cap docking facilities of specially a kind of optical fiber connector.

Background technology

Optical fiber is writing a Chinese character in simplified form for optical fiber, is a kind of fiber made of glass or plastics, can be used as light conduction tool, passes Defeated principle is " total reflection of light ".In daily life, it is conducted in electric wire than electricity in the conduction loss of optical fiber due to light Be lost it is much lower, optical fiber be used as long range information transmit.

And the connection of optical fiber needs to use optical fiber connector naturally, optical fiber connector is dismantled between optical fiber and optical fiber With the device of connection.Existing optical fiber connector uses the optical fiber connector of independent contact pin type dust cap, this independent contact pin type Dust cap have the following defects：On the one hand, due to dust cap and optical fiber connector be it is separated, and the volume of dust cap compared with It is small, therefore dust cap is nowhere stored and is easily lost, while plugging that dust cap is very laborious and dynamics is difficult to control；Another party Face, since dust cap is directly contacted with the end face of ceramic insertion core in optical fiber connector, dust cap can pollute ceramic insertion core, sternly The end face that ceramic insertion core may be damaged when weight, influences the performance of ceramic insertion core.The utility model proposes a kind of optical fiber companies thus The dust cap docking facilities of device are connect to solve the above problems.

Utility model content

The purpose of this utility model is to provide a kind of dust cap docking facilities of optical fiber connector, to solve above-mentioned background The problem of being proposed in technology.

To achieve the above object, the utility model provides the following technical solutions：A kind of dust cap docking of optical fiber connector The centerline of device, including the first dust cap and the second dust cap, the upper surface of first dust cap is equipped with semicircular arc Columnar projections are connected at the port of first dust cap anti-by the torsional spring inside semicircular arc columnar projections The inside top of dirt cover board, first dust cap is equipped with the two group T shape protrusions symmetrical about semicircular arc columnar projections, institute It states the first dust cap to be slidably connected with the second dust cap by the sliding rail on the second dust cap, T shapes protrusion position described in two groups In in sliding rail, second dust cap is equipped with the groove that more than one is used to mutually be clamped with the protrusion on optical fiber connector.

Preferably, the cross-sectional area of first dust cap is more than the cross-sectional area of second dust cap.

Preferably, rotation angle of the dust cover in perpendicular is 0 ~ 180 degree.

Preferably, the height of the protrusion is equal with the inner wall thickness of the second dust cap.

Compared with prior art, the utility model has the beneficial effects that：

1. the second dust cap is connected on optical fiber connector, the port of ceramic insertion core is located at the first dust cap internal cavities Interior, ceramic insertion core is not in direct contact with dust cap, avoids dust cap pollution ceramic insertion core or damage ferrule endface；

2. being movably hinged with dust cover by torsional spring at the port of the second dust cap, dust cover can be in perpendicular Rotation, the folding of dust cap can be directly controlled by the rotation angle of dust cover, is really realized convenient and efficient；

3. since the cross-sectional area of the first dust cap is more than the cross-sectional area of the second dust cap, and the first dust cap and second Dust cap is slidably connected, and when optical fiber connector docks, need to only unscrew the dust cover on the first dust cap, then first is prevented Dirt cap slides into the outer surface of the second dust cap, is unloaded without by dust cap, to prevent dust cap from losing.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

- 5 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of dust cap of optical fiber connector is to tipping It sets, including the first dust cap 1 and the second dust cap 2, the centerline of the upper surface of the first dust cap 1 is equipped with semicircular arc column Protrusion 3 is connected with dustproof cover at the port of first dust cap 1 by the torsional spring 5 inside semicircular arc columnar projections 3 The inside top of plate 6, first dust cap 1 is equipped with the two group T shape protrusions 10 symmetrical about semicircular arc columnar projections 3, First dust cap 1 is slidably connected by the sliding rail 9 on the second dust cap 2 with the second dust cap 2, T shapes described in two groups Protrusion is located in sliding rail 9, and the second dust cap 2 is equipped with more than one for recessed with 8 phase of the protrusion clamping on optical fiber connector 7 Slot 4, multi-faceted engaging so that fastness is more preferable.

Further, the cross-sectional area of the first dust cap 1 is more than the cross-sectional area of the second dust cap 2, then first is dust-proof The cross-sectional area of cap 1 is naturally larger than the cross-sectional area of optical fiber connector 7, this is allowed for when optical fiber connector 7 docks can be It carries out and dust cap need not be extracted in first dust cap 1, avoid the trouble that dust cap is easily lost；

Further, rotation angle of the dust cover 6 in perpendicular is 0 ~ 180 degree；

Further, the height of protrusion 8 is equal with the inner wall thickness of the second dust cap 2, and protrusion 8 is clamped with groove 4 in this way After the completion, protrusion 8 will not protrude the surface of the second protective jacket 2 so that movement of the T shapes protrusion 10 in sliding rail 9 does not hinder.

Operation principle：As shown in figure 3, when the utility model is used, the second dust cap 2 is socketed in optical fiber connector 7 On, and securely connect by the groove 4 on the second dust cap 2 is engaged with the protrusion 8 on optical fiber connector 7, prevent at this time Dirt cover board 6 is in closed state；When needing to realize the docking between optical fiber connector, by being located at semicircular arc columnar projections 3 Dust cover 6 at 1 port of the first dust cap is rotated 180 degree by interior torsional spring 5, then by the first protective jacket 1 by thereon The sliding in the sliding rail 9 of the second protective jacket 2 of T shapes protrusion, to expose the end of optical fiber connector 7, by another optical fiber Connector is inserted into, to realize the docking of optical fiber connector.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
