Because the size of plastic housing stopper slot 11 is incomplete same, and lock nut limit rib 15 can be adapted to plastic housing stopper slot 11,
Therefore, and if only if after lock nut limit rib 15 is aligned completely with plastic housing stopper slot 11, and lock nut 2 could be installed on to the head of plastic housing 9
End, otherwise, the stop due to plastic housing limit rib 12 or plastic housing stopper slot 11 to lock nut limit rib 15 causes lock nut 2 not install
In in plastic housing 9.When lock nut limit rib 15 is aligned completely with plastic housing stopper slot 11, and lock nut 2 is installed on the head end of plastic housing 9
When, the lock nut limit rib 15 of lock nut 2 is located at the lower section of plastic housing ring 4, at this point it is possible to which lock nut 2 is rotated relative to plastic housing 9 so that lock
Cap limit rib 15 staggers with plastic housing stopper slot 11, i.e., lock nut limit rib 15 is in non-fully alignment with plastic housing stopper slot 11,
So as to utilize plastic housing 4 cooperation to lock nut limit rib 15 of ring so that lock nut 2 can not be pulled out from the head end of plastic housing 9, meanwhile, utilize
Cooperation between lock nut 2 and the external diameter size and shell 1 of plastic housing 9, can realize that the position of lock nut 2 is fixed, i.e., lock nut 2 is in plastic housing 9
On can only rotate, and can not realize from the pull-out of the head end of plastic housing 9.
When it is implemented, when needing to change lock nut 2, it is only necessary to which lock nut limit rib 15 is complete again with plastic housing stopper slot 11
Full alignment, and if only if after the lock nut limit rib 15 of lock nut 2 is aligned with the plastic housing stopper slot 11 on plastic housing ring 4, due to plastic housing ring 4
Lock nut limit rib 15 can not be stopped again, can realize and pull out lock nut 2 from the head end of plastic housing 9.In addition, in order to quickly realize lock nut
The rapid alignment of limit rib 15 and plastic housing stopper slot 11, can be respectively arranged to what alignment was indicated on lock nut 2 and plastic housing 9
Arrow, the complete of lock nut limit rib 15 and plastic housing stopper slot 11 is can be only achieved when only corresponding arrow is completely to correspondence
Full alignment, the particular location of arrow and specific instruction state can carry out selection setting as needed, be specially this
Known to technical field personnel, here is omitted.
To sum up, lock nut 2 can be directly mounted at the head end of plastic housing 9, can also be directly from plastic housing 9 when changing lock nut 2
Head end is pulled out, and using the cooperation of lock nut limit rib 15 and plastic housing stopper slot 11, can ensure that lock nut 2 and the indirect stability of plastic housing 9
With reliability, the purpose of lock nut 2 and the fast assembling-disassembling of plastic housing 9 is reached.
When it is implemented, the top in the lock nut 2 is convexly equipped with symmetrical lock nut fixed block 6.In order to constitute one
The solar energy AC connector of completion, general connector needs two connectors for including cooperating, and lock nut 2 can be set
On any connector, it can be selected as needed, specially known to those skilled in the art, here is omitted.
After lock nut 2 is arranged on a connector, it is possible to use lock nut fixed block 6 and another connector clamping, two connectors are realized
It is fastenedly connected.
The utility model is provided with some stress relief holes 10 in the end surface of the head end of plastic housing 9, passes through stress relief hole 10
It can effectively reduce to set in stress, plastic housing 9 and plastic housing stopper slot 11 and plastic housing limit rib 12 are set on plastic housing ring 4, plastic housing ring 4,
Lock nut limit rib 15 is set in lock nut 2, and and if only if, and lock nut limit rib 15 is aligned completely with the plastic housing stopper slot 11 on plastic housing ring 4
When, lock nut 2 can be installed on to the head end of plastic housing 9；After lock nut 2 is installed in plastic housing 9, the lock nut of and if only if lock nut 2 is spacing
When muscle 15 is aligned with the plastic housing stopper slot 11 on plastic housing ring 4, the lock nut 2 for being installed on the head end of plastic housing 9 could be pulled open from plastic housing 9
Separation, can realize the fast assembling-disassembling of lock nut 2 and connector, improve the installation of lock nut 2 with changing efficiency, safe and reliable.
