Set has：Access road, swan-neck and exit passageway, the access road, the swan-neck and the exit passageway connect successively
Logical, there is the access road entrance, the outer surface of the swan-neck to have multiple grooves being mutually parallel, the exit passageway
With outlet, it is characterised in that：The tail sleeve is the ducted body in truncated cone-shaped, and the side of the tail sleeve is heavy wall, and the other side is
Thin-walled, the tail sleeve also have：Shape retaining member, the shape retaining member are embedded in the heavy wall, the shape retaining member
Have：First holding rod and the second holding rod, first holding rod are mutually parallel with second holding rod.
Preferably, second holding rod than first holding rod closer to the thin-walled.
Preferably, the shape retaining member also has：Connecting rod, the connecting rod simultaneously with first holding rod and institute
It states the second holding rod and forms fixation.
Preferably, two connecting rods are located at close to the position at the tail sleeve both ends.
Preferably, the tail sleeve also has：Baffle ring, the baffle ring are in truncated cone-shaped, and the baffle ring is from the exit passageway
Inner wall extends toward the outlet, and there is gear mouth, the gear mouth to be aligned with the outlet in the middle part of the baffle ring.
The beneficial effects of the utility model are：Tail sleeve with above structure not only may be implemented to be bent and restore behaviour
Make, and its compression strength is high, service life is long, and applicability is good.
Description of the drawings
Fig. 1 be the utility model is related to tail sleeve schematic diagram；
Fig. 2 be the utility model is related to tail sleeve sectional view in an axial direction.
Specific implementation mode
The utility model is further elaborated below in conjunction with the accompanying drawings：
It is emphasized that the term " first " in the utility model, " second ", " third " are used for description purposes only, and
It should not be understood as indicating or imply relative importance or implicitly indicate the quantity of indicated technical characteristic.It defines as a result,
" first ", " second ", " third " feature can explicitly or implicitly include at least one of the features.The utility model is retouched
In stating, the meaning of " plurality " is at least two, such as two, three etc., unless otherwise specifically defined.The utility model
In embodiment the directional instruction (such as up, down, left, right, before and after ...) of institute be only used for explanation a certain particular pose (such as
Shown in attached drawing) under relative position relation, motion conditions etc. between each component should if the particular pose changes
Directionality instruction also correspondingly changes correspondingly.In addition, term " comprising " and " having " and their any deformations, it is intended that cover
It covers and non-exclusive includes.Such as it contains process, method, system, product or the equipment of series of steps or unit and does not limit
In the step of having listed or unit, but further include the steps that optionally do not list or unit, or further include optionally for
The intrinsic other steps of these processes, method, product or equipment or unit.
As shown in Figure 1, tail sleeve is generally in the ducted body of truncated cone-shaped, have：Access road 1, swan-neck 2 and exit passageway
3.Access road 1, swan-neck 2 and exit passageway 3 are sequentially communicated, and in optical fiber connector assembling process, fiber optic cable is from entrance
Channel 1 enters tail sleeve, passes through swan-neck 2 to be drawn from exit passageway 3, is finally connect with optical fiber connector.Wherein, since tail sleeve is whole
Body is in the shape of round platform, therefore can ensure that tail sleeve passes through the circular hole of wiring.
In conjunction with shown in Fig. 2, there is access road 1 entrance 10, the outer surface of swan-neck 2 to have multiple grooves 20, i.e. groove
20 are arranged from the outer surface depressions of swan-neck 2, and multiple grooves 20 are mutually parallel, and exit passageway 3 has an outlet 30, entrance 10 and go out
Mouth 30 is located at the both ends of tail sleeve.The side of tail sleeve is heavy wall 101, and the other side is thin-walled 102, and the thickness of heavy wall 101 is more than
The thickness of thin-walled 102, i.e. entrance 10 and the end for exporting 30 positions not at tail sleeve center, entrance 10 or outlet 30 and tail sleeve
Face and non-concentric.
Also there is tail sleeve shape retaining member 4, shape retaining member 4 to be embedded in by way of in-mould injection in heavy wall 101, shape
Shape holder 4 is formed by metal material.Shape retaining member 4 has：First holding rod 41, the second holding rod 42 and connecting rod 43,
First holding rod 41 is mutually parallel with the second holding rod 42, and 42 to the first holding rod 41 of the second holding rod is closer to thin-walled 102, even
Extension bar 43 forms with the first holding rod 41 and the second holding rod 42 fix simultaneously.In the present embodiment, connecting rod 43 be two, two
A connecting rod 43 is located at close to the position at tail sleeve both ends.
When tail sleeve needs restore from flexuosity, the ductility of the first holding rod 41 and the second holding rod 42 can be passed through
Tail sleeve is set to restore to original state.Due to being provided with the first holding rod 41 and the second holding rod 42, relative to traditional tail
For set, compression strength higher, shape retaining member 4 is not easy to break, and service life is long.In addition, connecting rod 43 can prevent first
Holding rod 41 and the second holding rod 42 rotate；And two connecting rods 43 can make the first holding rod 41 and the second holding rod 42
Head and the tail action is consistent, and further increases the compression strength of tail sleeve.
It is in truncated cone-shaped that tail sleeve, which also has baffle ring 5, baffle ring 5, and baffle ring 5 extends from the inner wall of exit passageway 3 toward outlet 3.Baffle ring 5
There is gear mouth 50, gear mouth 50 to be aligned with outlet 30 at middle part.During tail sleeve is bent, tail sleeve itself will produce deformation, and light
The starting stage that fibre is bent in tail sleeve will keep original shape, at this point, optical fiber may be back to from " contracting " from outlet 30 in tail sleeve
Portion causes the assembly that optical fiber connects machine inconvenient.The size of the gear 50 size ratio optical fiber of mouth of baffle ring 5 is small, when optical fiber passes through gear mouth 50
Afterwards, baffle ring 5 prevents optical fiber " contracting " to be back to inside tail sleeve the mobile formation resistance of optical fiber.
As it can be seen that the tail sleeve with above structure, not only may be implemented bending and recovery operation, but also its compression strength is high,
Service life is long, and applicability is good.
Embodiment described above, only the preferred embodiments of the utility model, are not to limit the implementation model of the utility model
It encloses, therefore the equivalent change or modification that all structure, feature and principles according to described in present utility model application the scope of the claims are done, it should all
It is included in the scope of the utility model patent application.
