The utility model discloses a dustproof cap of optical fiber port, comprising a handheld body inserted into the optical fiber port and a plug inserted into the optical fiber port; the optical fiber port is provided with an optical fiber insertion core and a blocking arm for protecting the optical fiber insertion core; a front end of the plug is provided with a plug head, a rear end thereof is provided with a plug body; a middle part of the plug body is a concave hole; an external diameter on the front end of the plug head is less than that on the rear end of the plug head; a rear end on the rear end of the plug head is an oblique surface which is tangential to the plug body direction from the plug head direction, so that a clamping position is formed between the plug head and the plug body; while the plug is inserted into the optical fiber port, the blocking arm of the optical fiber port is clamped in the clamping position of the plug. The utility model guarantees that the dustproof cap is not dropped from the optical fiber port in the transportation process, guarantees that the optical fiber port is isolated from the pollutant before using, and guarantees the use quality via double protection of the concave hole and the clamping position.
Description
[technical field]
The utility model relates to a kind of dust cap of fiber port.
[background technology]
Dust cap is used for covering fiber port to playing a protective role to the light face; prevent fiber port attention cleaning and protection before use; cause pollutant to enter fibre core, cause the decline of light path coupling efficiency or block light path fully, even also can cause the permanent damage of fibre core end face.
In prior art as shown in Figure 1, the dust cap of fiber port adopts the verge of opening of boss and fiber port to cooperate, cause by boss and the friction force that closely contacts generation, so resistance is less, after the vibrations of fiber port through long-distance transport, the less dust cap of this resistance that comes off comes off from fiber port easily, makes to cause pollutant to enter fibre core, cause the decline of light path coupling efficiency or block light path fully, even also can cause the permanent damage of fibre core end face.
[utility model content]
At the shortcoming that existing fiber port dust cap comes off easily, the utility model provides a kind of dust cap of fiber port, have simple in structure, adeciduate advantage in the vibrations.
The dust cap of the fiber port that the utility model discloses, comprise the hand-held body of filling in fiber port and the stopper of filling in fiber port, the blocking arm of fiber stub and protection fiber stub is arranged in the fiber port, the stopper front end is a chock plug, the rear end is a cock body, and the cock body middle part is a shrinkage pool; Chock plug front end external diameter is less than chock plug rear end external diameter, and the rear end of chock plug rear end is the inclined-plane from the tangential cock body direction of chock plug direction, makes to form screens between chock plug and the cock body.After stopper was filled in fiber port, the blocking arm of fiber port was stuck in the screens of stopper.
The disclosed dust cap of the utility model, overcome the shortcoming that original dust cap comes off easily, double protection by shrinkage pool and screens, can guarantee in transit, dust cap can not fall down from fiber port, guaranteed that fiber port all isolates with pollutant before use, guaranteed its service property (quality).

[embodiment]
Below in conjunction with drawings and embodiments the utility model is further specified.
As shown in Figure 1, be the schematic perspective view of original dust cap 100 and fiber port 110.Dust cap 100 comprises hand-held body 101, stopper 102 and baffle plate 103, and stopper 102 is provided with multiple tracks boss 104.Fiber port 110 is the structure that is provided with according to standard, the inner structure of narration explanation for convenience, and in the institute of the present utility model drawings attached, illustrated fiber port 110 loam cake that all do not draw.Fiber stub 111 is arranged on the middle part of fiber port 110, the periphery of fiber stub 111 also is provided with blocking arm 112, fill in the perforate of fiber port 110 when stopper 102 after, the perforate by boss on the dust cap 110 11 and fiber port contacts closely that the friction force of generation causes, so resistance is less.
As shown in Figure 2, be the stereographic map of the disclosed dust cap of the utility model.Dust cap 200 comprises hand-held body 201, stopper 202 and baffle plate 203.The front end of stopper 202 is a chock plug 204, and the rear end is a cock body 206, is provided with screens 207 between chock plug 204 and the cock body 206.Chock plug 204 is dug shrinkage pool 205, and the size of shrinkage pool 205 and shape are provided with according to the fiber stub 111 of fiber port 110, the perforate coupling of the size of cock body 206 and shape and light port one 10.Stopper 202 and hand-held body 201 are in the two ends of baffle plate 203 respectively, and area is greater than the area of stopper 202 rear ends, and after assurance stopper 202 was filled in fiber port, baffle plate 203 can block the perforate of fiber port 110.The needs of the shape ergonomics of hand-held body 201 can be arranged to multiple shape, do not limit this shape that the utility model is showed, in the utility model, the rear end of hand-held body 201 is bigger, conveniently holds and takes.
As shown in Figure 3, be the vertical view of disclosed dust cap of the utility model and the fiber port that matches.From overlooking direction, the outer wall of chock plug 204 is a front-thin-rear-thick wedge shape, wedge shaped end is following incisal bevel, be that outer wall front end external diameter is less than the rear end external diameter, such setting is to also have surplus for the rear end at outer wall cuts out 208 backs, inclined-plane on thickness, and the inclined-plane of incisal bevel and stopper 202 rear ends forms screens 207 under making.Cock body 206 is own bigger than the volume of chock plug 204, and therefore, the position of screens 207 has just become a relative low level on stopper 202 length.The front end of the blocking arm 112 of the periphery of fiber stub 111 has hook formation.
As shown in Figure 4, be the assembling section of disclosed dust cap of the utility model and fiber port.After stopper 202 is filled in fiber port 110, chock plug 204 stretches in the blocking arm 112 of fiber port 110, the shrinkage pool 205 of chock plug 204 wraps fiber stub 111, the hook formation of blocking arm 112 just is stuck in the screens 206, therefore, the wedge shape of chock plug 204 outer walls also can only be arranged on fiber port 110 has on the blocking arm face.
What present embodiment was showed is a typical example, and in practice, the blocking arm 112 of fiber stub 111 peripheries can be one or more surfaces, and therefore, stopper 202 can be provided with screens in one side or multiaspect and be used for blocking blocking arm 112.
Compare original dust cap, the dust cap that the utility model discloses has difficult drop-off, protects tight advantage.
