when the connector 1 and the adapter 2 need to be locked, when the connector 1 is inserted into the adapter 2 by the handheld connector housing 13, when the inclined surface of the first protrusion 102 on the insertion portion 101 contacts the inclined surface of the buckle 201 on the adapter body 20, the buckle 201 is pushed to expand outwards, and as the insertion depth increases, the end surface of the buckle 201 abuts against the end surface of the unlocking ring 12 (the leftmost end of the extension portion 122) and pushes the unlocking ring 12 to compress the elastic member 11 backwards. When the connector 1 is inserted in place, the first protrusion 102 on the insertion portion 101 and the buckle 201 on the adapter body 20 are buckled, the shape of the buckle 201 is reset, the buckle is separated from mutual support with the end face of the unlocking ring 12, the unlocking ring 12 moves forward under the action of the elastic piece 11, when the buckle 201 on the adapter body 20 is pressed when the buckle moves to the maximum stroke, and the buckle 201 cannot be expanded and deformed due to the compression effect of the unlocking ring 12, so that firm tensile resistance is guaranteed.
When the connector 1 and the adapter 2 need to be unlocked, the connector outer sleeve 13 is held by hand or pulled backwards through the pull rope 14, the outer sleeve protrusion 131 on the inner side of the connector outer sleeve 13 drives the unlocking ring 12 to move backwards, and when the unlocking ring 12 is separated from being in contact with the buckle 201. The connector body 10 moves backwards, the buckle 201 is expanded through the first protrusion 102, the releasing action is completed, the connector 1 is continuously pulled until the connector 1 and the adapter 2 are separated from contact, and therefore, the whole unlocking process is completed.
In summary, after the unlocking ring 12 is arranged, when the connector is in butt joint with the adapter, the unlocking ring 12 is firmly pressed at the clamping joint of the connector and the adapter under the driving force provided by the elastic part 11, so that the buckle 201 of the adapter cannot be expanded and deformed, the firm tensile force is ensured, and the locking force required by most outdoor preformed end connectors can be met.
