Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
As depicted in figs. 1 and 2:In order to coordinate by the connection of lock nut 10 and lock ring 5, male connector 16 and mother can ensure that
The stability and reliability connected between head connector 16, the utility model includes male connector 16, is connected with the male
The female connector 15 of the matching connection of body 16 and the lock nut 10 for locking male connector 16 and female connector 15;It is described
Lock nut 10 is installed on the male connector 16;Top in the lock nut 10 is provided with lock nut fixed block 17, in the female
The rotation neck 41 that lock ring 5 is set on connector 15 and allows lock nut fixed block 17 to set;The lock ring 5 is provided with lock nut button
45, the upper end of lock nut 10 is provided with locking hole 19;The lock nut fixed block 17 of lock nut 10 is embedded in rotation neck 41 and moved in place
Afterwards, the lock nut button 45 of lock ring 5 can be caught in the locking hole 19 of lock nut 10.
Specifically, after male connector 16 is connected with each other with female connector 15, solar energy connector can be formed, male connects
The connection fit form that can be commonly used between junctor 16 and female connector 15 using the art, male connector 16 and female
, will be in company by connecting the connection status that retaining mechanism can keep current, it is to avoid under external force after connector 15 is connected
The male connector 16 and female connector 15 for connecing state are pulled open.
In the utility model embodiment, the lock nut 10 of connection retaining mechanism is installed on the end of male connector 16, works as public affairs
When head connector 16 is connected with each other with female connector 15, the binding site of female connector 15 and male connector 16 is in lock nut
In 10.Because lock nut 10 is installed on the end of male connector 16, when the lock nut fixed block 17 of lock nut 10 is embedded in female connection
After in the rotation neck 41 of body 15, using the mating reaction between lock nut fixed block 17 and rotation neck 41, i.e., it can avoid in axle
To external force effect under the male connector 16 in connection status and female connector 15 are pulled open.When it is implemented, as mother
When head connector 15 is connected with each other with male connector 16, rotation neck 41 rotates neck adjacent to the end of male connector 16
41 is curved, i.e., after lock nut fixed block 17 is caught in rotation neck 41, by mutual between female connector 15 and lock nut 10
Rotate, lock nut fixed block 17 can be caused to reach effective cooperation with rotation neck 41, it is to avoid lock nut fixed block 17 and rotation neck 41
Between separation.After lock nut fixed block 17 is embedded in rotation neck 41, lock nut fixed block 17 and the joint portion for rotating neck 41 are equal
Encirclement is carried out by lock nut 10 to block.When needing female connector 15 to be separated with male connector 16, it is only necessary to by lock nut 10 with
