- 9 -As shown in Figs. 19 to 22, the locking and unlocking principles of the connector and the adapter in the present invention are introduced herein.
When it is necessary to lock the connector 1 and the adapter 2, during the process of inserting the connector 1 into the adapter 2 by holding the connector housing 13, when the inclined plane of the first protrusion 102 on the insertion portion 101 contacts the inclined plane of the fastener 201 on the adapter main body 20, the fastener 201 will be pushed to open outward. As the insertion depth increases, the end surface of the fastener 201 resists on the end surface of the unlocking ring 12 (the leftmost end of the extension portion122) and pushes the unlocking ring 12 to compress the elastic part 11 backward. When the connector 1 is inserted into place, the first protrusion 102 on the insertion portion 101 forms a snap fit with the fastener 201 on the adapter main body 20, and the fastener 201 is reset in shape and separated from the mutual resistance with the end surface of the unlocking ring 12. At this time, the unlocking ring 12 will move forward under the force of the elastic part 11. When the unlocking ring 12 moves to the maximum stroke, the fastener 201 on the adapter main body 20 is pressed. Due to the pressing action of the unlocking ring 12, the fastener 201 cannot produce the deformation of opening, so as to ensure firm tensile resistance.
When it is necessary to unlock the connector 1 and the adapter 2, the connector housing 13 is pulled backward by holding or by means of the drawstring 14. The housing protrusion 131 on the inner side of the connector housing 13 drives the unlocking ring 12 to move backward.
When the unlocking ring 12 is out of contact with the fastener 201, the connector main body 10 moves backward, expands the fastener 201 through the first protrusion 102, completes the tripping action, and continues to pull the connector 1 until the connector 1 is completely out of contact with the adapter 2, that is, all the unlocking process is completed.
In summary, after the connector in the present invention sets the unlocking ring 12, when the connector is butt joint with the adapter, under the driving force provided by the elastic part 11, the unlocking ring 12 will be firmly pressed and held at the clamping position between the connector and the adapter, so that the fastener 201 of the adapter cannot produce the deformation of opening, so as to ensure firm tensile resistance and meet the locking force required by most outdoor preformed end connectors.
At the same time, the present invention further provides an optical fiber connection assembly, which comprises a connector 1 and an adapter
When it is necessary to lock the connector 1 and the adapter 2, during the process of inserting the connector 1 into the adapter 2 by holding the connector housing 13, when the inclined plane of the first protrusion 102 on the insertion portion 101 contacts the inclined plane of the fastener 201 on the adapter main body 20, the fastener 201 will be pushed to open outward.

When the unlocking ring 12 moves to the maximum stroke, the fastener 201 on the adapter main body 20 is pressed. Due to the pressing action of the unlocking ring 12, the fastener 201 cannot produce the deformation of opening, so as to ensure firm tensile resistance.
When it is necessary to unlock the connector 1 and the adapter 2, the connector housing 13 is pulled backward by holding or by means of the drawstring 14. The housing protrusion 131 on the inner side of the connector housing 13 drives the unlocking ring 12 to move backward.
When the unlocking ring 12 is out of contact with the fastener 201, the connector main body 10 moves backward, expands the fastener 201 through the first protrusion 102, completes the tripping action, and continues to pull the connector 1 until the connector 1 is completely out of contact with the adapter 2, that is, all the unlocking process is completed.
In summary, after the connector in the present invention sets the unlocking ring 12, when the connector is butt joint with the adapter, under the driving force provided by the elastic part 11, the unlocking ring 12 will be firmly pressed and held at the clamping position between the connector and the adapter, so that the fastener 201 of the adapter cannot produce the deformation of opening, so as to ensure firm tensile resistance and meet the locking force required by most outdoor preformed end connectors.
