Description
Technical field
This utility model is related to technical field of optical fiber communication, is related specifically to a kind of fiber stub dust cap.
Background technology
Optical fiber makes communication generate revolutionary change, and it is a kind of utilization light in fiber made by glass or plastics
Total reflection principle and the light conduction instrument reached, are a kind of very accurate communication devices, thus generally dust, dirt and its
He easily produces interference to the optical signal transmission between optical fiber by pollutant, so as to affect the transmission of communication data.Patent No.
The file of CN200920260097.4 discloses a kind of optical dust-proof cap, and its structure is that the cavity in the cap sleeve of dirt-proof boot is provided with two
Individual cylindrical cavity, when lock pin inserts cap sleeve, lock pin is contacted with the side Bi Shi faces of cylindrical cavity, increases insertion core end face pollution general
Rate, and insertion core end face easily touches the inwall of circular cavity, and insertion core end face certainly will be polluted, therefore it is existing common dust-proof
Cap can not effectively play dust-proof effect, and steam, dust etc. are still had when lock pin wears dust cap affects end face matter
The phenomenon of amount occurs, and then affects the accuracy of fibre optic data transmission.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, to propose a kind of fiber stub dust cap, to overcome
Existing dust cap can cause steam, dirty phenomenon to insertion core end face.
To solve above-mentioned technical problem, this utility model provides a kind of fiber stub dust cap, including cap sleeve and cap, institute
State the cavity in cap sleeve and be provided with bulge loop and some guiding ribs；
The profile of the cap sleeve is cylinder, and the porch of the end of cap sleeve is provided with frustum cone structure, the frustum cone structure
Chamfering is provided with, the guiding rib is axially arranged at the inwall of cap sleeve and is located at frustum cone structure, and the bulge loop is radially
Be arranged at the inwall of cap sleeve and be located remotely from frustum cone structure, the diameter with diameter greater than the bulge loop at the guiding rib,
The cavity of the cap sleeve is provided with vacuum chamber at bulge loop, and the vacuum chamber is provided with interior chamfering；
The cap is cylinder, and the cap sleeve is connected with cap closing, and the external diameter of the cap is more than the external diameter of cap sleeve,
Two end faces of the cylinder of described cap are provided with chamfering；
Further, the number of the guiding rib is four.
Compared to prior art, this utility model has the advantages that：The dirt-proof boot is set in the cavity inside of cap sleeve
Bulge loop and some guiding ribs are put, guiding rib can clamp lock pin and play fixation, and the unique design of bulge loop has sealing function,
Make the front little half part of lock pin become preferable vacuum, prevent the air of cavity latter half from entering front end, and then avoid lock pin
There is the dirty of steam and dust etc in end face, and lock pin and guiding rib and bulge loop in cap sleeve cavity are linear contact lay, cap
The vacuum chamber of set is provided with interior chamfering, it is to avoid lock pin front end touches inwall, and it is dirty that these structure designs all avoid lock pin contact
Dye, so as to ensure that insertion core end face quality, therefore the dirt-proof boot internal cavities are reasonable in design, are completely embedded, and dust-proof effect is splendid.
Description of the drawings
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail.
Fig. 1 is sectional view of the present utility model；
Fig. 2 is left view of the present utility model；
Enlarged drawings of the Fig. 3 for this utility model guiding rib.
Specific embodiment
In order to be better understood from the purpose of this utility model, construction featuress and function, below in conjunction with the accompanying drawings to this practicality
The structure of new preferred implementation, the course of work and function are described in detail.
As shown in figure 1, a kind of fiber stub dust cap, including cap sleeve 1 and cap 2, the profile of cap sleeve 1 is cylinder, cap
The porch of the end of set 1 is provided with frustum cone structure 101, and frustum cone structure 101 is provided with chamfering, and the cavity of cap sleeve 1 is provided with convex
Ring 103 and some guiding ribs 102 (as shown in Figure 2 and Figure 3), guiding rib 102 are axially arranged at the inwall of cap sleeve 1 and are located at and lean on
At nearly frustum cone structure 101, bulge loop 103 is radially arranged at the inwall of cap sleeve 1 and is located remotely from frustum cone structure 101, guiding rib
The diameter with diameter greater than at bulge loop 103 at 102, the cavity of cap sleeve 1 are provided with vacuum chamber 104, vacuum chamber at bulge loop 103
104 are provided with interior chamfering；
The cap 2 is cylinder, and the cap sleeve 1 is connected with the closing of cap 2, and the external diameter of the cap 2 is more than cap sleeve 1
External diameter, two end faces of the cylinder of described cap 2 are provided with chamfering 201.
When in the cap sleeve 1 for lock pin 3 being inserted this utility model dirt-proof boot, it is provided with down at the frustum cone structure 101 of cap sleeve 1
Angle, plays a part of to avoid the front end of lock pin 3 from colliding with the cavity inner wall of cap sleeve, when the front end of lock pin 3 is reached at guiding rib 102
When, the diameter of guiding rib 102 is consistent with 3 diameter of lock pin, forms automatic guide, and then plays a part of the lock pin 3 that is fixedly clamped, when
When lock pin 3 enters bulge loop 103, as the internal diameter of bulge loop 103 is less than the external diameter of lock pin, therefore the outer of lock pin 3 can be now compressed
Footpath, plays sealing function, makes the vacuum chamber 104 foremost of lock pin 3 reach preferable vacuum state, so as to avoid the powder in the external world
Dirt, steam etc. enter vacuum chamber 104, final to ensure the clean of 3 end face of lock pin.
A kind of fiber stub dust cap of this utility model arranges bulge loop and some guiding ribs by the cavity inside in cap sleeve,
Guiding rib can clamp lock pin and play fixation, and the unique design of bulge loop has sealing function, make the front little half part of lock pin
Become preferable vacuum, it is to avoid the dirty of steam and dust etc occurs in insertion core end face, and leading in lock pin and cap sleeve cavity
Linear contact lay is to muscle and bulge loop, the vacuum chamber of cap sleeve is provided with interior chamfering, it is to avoid lock pin front end touches inwall, these structures
Design all avoids lock pin contact stain, and so as to ensure that insertion core end face quality, therefore the dirt-proof boot internal cavities are reasonable in design,
It is completely embedded, dust-proof effect is splendid.
