Optical fiber is fixed on wherein.
As shown in figure 8, crimp rings 15 be becket, by lock ring bunch set 14 small end, so as to will bunch cover 14 in
Optical cable fix, prevent the optical cable in bunch set 14 from rocking, the optical fiber picked out from separated time unit 13 caused to pull.
Bunch set 14 and crimp rings 15 cause wire inlet unit 12 is firm to be connected on connector body 11, while bunch set
14 and crimp rings 15 can also form good protection to the root of optical fiber, the bending torsion of optical fiber is suitable by connector body 11
Being transitioned on wire inlet unit 12 for profit, further forms optical fiber good protection.
Wire guide 122 is in non-time by forming interference fit connection, wire guide 122 between bunch set 14 and wire barrel 110
Turn shape.In the present embodiment, wire guide 122 is square poroid, and the distance of the opposite side of square hole is slightly less than the major diameter of bunch set 14.
The wire guide 122 of non-revolved body shape locally provides larger deformation space when being interference fitted connection with wire barrel 110, even
Locally there is larger deformation quantity so that the interference fit connection between component is more firm when connecing.
The cross section of connector body 11 is square and, connector sheet corresponding with the interface that fiber-optic sub-line connector 1 connects
Connection clip 16 is additionally provided on body 11, connection clip 16 has the shrapnel 161 tilted from connector body 11.Pass through the shrapnel of tilting
161 so that when being inserted into interface, flexible deformation, the elasticity supervened occur connector body 11 for the shrapnel 161 of tilting
Restoring force enhances the attachment force of connector body 11 and interface so that the connection of connector body 11 is more firm.
As shown in figure 9, connection clip 16 is an integral structure, connector body 11 is equipped with mounting groove 1110, connection clip 16
It is embedded in mounting groove 1110 equal with 11 surface of connector body, shrapnel 161 is from the direction of separated time unit 13 towards inlet wire list
The direction expansion of member 12, and when the free end of shrapnel 161 is abutted with connector body 11,161 opposing connector body 11 of shrapnel
It arches upward.
In the present embodiment, connection clip 16 bends the one-piece member formed for thin plate, by cutting, bending forming, has
Preferable elasticity, by certain flexible deformation lock ring on connector body 11.Connection clip 16 is in Contraband shape, from connector lower cover
112 clip in connector upper cover 111 upwards.One end of shrapnel 161 is connected with connection clip 16, and the other end is free end, shrapnel 161
There is an inclined gradient with respect to connection clip 16, end is parallel with the side of connection clip 16, so that the freedom of shrapnel 161
When end is abutted with connector body 11,161 opposing connector body 11 of shrapnel arches upward.So that fiber-optic sub-line connector 1 exists
When being plugged in corresponding interface, larger deformation occurs for shrapnel 161,
It is split type detachable structure between connection clip 16 and connector body 11, connector body 11 is connect being inserted into
When in mouthful, shrapnel 161 is deformed to the position equal with connector body 11, and there are one inclined gradient, small end courts for the tool of shrapnel 161
To direction of insertion, become larger with the insertion deformation of connector body 11, attachment force gradually increases.By in connector body
Grafting positive stop lug boss is set on 11, and so as to continuing into for limit fibre tee connector 1, butted line port forms protection.
In all examples being illustrated and described herein, any occurrence should be construed as merely illustrative, without
It is as limitation, therefore, other examples of exemplary embodiment can have different values.
It should be noted that：Similar label and letter represents similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined, then it further need not be defined and explained in subsequent attached drawing in a attached drawing.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot limitation of the scope of the invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.
