Part can be axially moved along sleeve, and elastic part includes but is not limited to spring, elastic slice etc..
Figure 11-12 is please referred to, is the structural schematic diagram of connector assembly outside another embodiment of the present invention error-unlocking prevention room,
In this embodiment, the unlocking prevention key 4 is located in the bayonet 15 of socket, when socket plug locking, the coupling nut 12
The guide portion of the interior unlocking prevention key 4 along bayonet 15 of convex key 1 rotates, and is engaging in place after crossing the unlocking prevention key 4 with bayonet 15, and
Thereafter end face block is on the limiting section of unlocking prevention key 4.In this embodiment, the clearance channel 7 is located at the connection in 1 outside of convex key
On nut wall body, which generates outwardly radial deformation and provides deformation space when being squeezed for the convex key 1.I.e. at this
In embodiment, when plugs and sockets plugs together locking, it is rotatablely connected nut, the convex key 1 in the coupling nut is slided in bayonet, directly
Along the guide portion of unlocking prevention key 4 continue to move up to the convex key 1 and cross the unlocking prevention key 4 and reenter in bayonet, engages with bayonet
In place, and by the limiting section block of unlocking prevention key 4 it limits, prevents coupling nut reversion from causing to misread lock.
To sum up, the present invention by the cooperation of unlocking prevention key in convex key in coupling nut and plug bayonet realize unlocking prevention or
The anti-misunderstanding of connector assembly is realized by the cooperation of the unlocking prevention key on positioning and locking key 2 in coupling nut and plug cylinder
Lock.
Figure 13 and 14 is please referred to, in yet another embodiment of the invention, the positive stop key 3 is movably arranged on sleeve, can be
It is compressed when being squeezed into sleeve.Specifically, the positive stop key 3 is arranged in the through-hole on sleeve, the wall body of 3 side of positive stop key
It is connect with the wall body at 19 edge of through-hole.
In embodiments of the present invention, the positive stop key 3 is located in keyway 6.The positive stop key 3 is located in sleeve keyway 6
In through-hole 19, the wall body of 3 side of positive stop key is connect with the wall body at 19 edge of through-hole, so that the positive stop key is by external connection spiral shell
It when the extruding of cap, can be deformed into sleeve, when coupling nut crosses the key, which sets back.
In this embodiment, the positive stop key 3 includes the gentle portion of rear end and the protrusion of front end, and on rear side of the gentle portion
Connect with sleeve wall body, when coupling nut installation when, in positioning and locking key squeeze positive stop key 3 from the front to the back, the positive stop key 3
The protruding portion of front end under pressure, is deformed into cylinder, and but not limited to this.
In the another implementation of the present invention, the positive stop key both ends are gentle, and centre is prominent, the gentle portion front end of front end and set
The connection of barrel body, but not limited to this.
