It introduces to entrance hole 12, after flexible water material 29, is connect with plug lock pin 5.
Simple automatically lock round plastic water-proof connector of the invention, the implementation process for being inserted into connection are as follows：
Plug (such as tail portion locking head 11 or pin tail ontology 10 or plug inner housing 8) is held on the other hand, the other hand is held
Plug is coupled the major key position on 6 left part outer cylinder of shell and indicates 14 alignment socket outer housing of arrow, 1 column jacket by jack housing body 1
Middle face major key position mark slot 13 carry out to insert, when a plug is to be inserted into the socket, on 1 right part ladder hole wall of jack housing body
When cantilever snaps 4 are inserted into plug inner housing periphery 21 of 8 left part of plug inner housing, cantilever snaps 4 can be tilted slowly, this
When cantilever snaps 4 cantilever snaps outer end face 28 top to plug coupling shell 6 avoiding hollow groove inner face step 17, force plug coupling
It closes shell 6 to move right, when cantilever snaps 4 enter cantilever snaps slot 24, cantilever snaps outer end face 28 is sprung back, and exits avoiding hollow groove
Inner face step 17, plug couple shell 6 and push underthrust to be moved to the left in the elastic force of locking spring 7, and plug couples shell 6 and springs back
When in place, inner wall touch the outer wall of jack housing body 1, so that cantilever snaps 4 can not tilt, thus, it is convex in cantilever snaps 4
Button is firmly stuck in cantilever snaps slot 24, to achieve the effect that locking.Simple automatically lock round plastic of the invention is anti-
When water connector connection locking, 23 compression seal gasket 3 of plug inner casing end face, to realize IP67 degree of protection.
The implementation process of simple automatically lock round plastic water-proof connector of the invention, unlock is as follows：
It turns right and plug is pulled to couple shell 6, formation limiting stand at ladder is developed in plug coupling to be fallen back on shell right side 19
3 avoiding hollow grooves 16 of rank 22, at this moment plug coupling shell 6 just can be with the convex buckle in empty avoiding cantilever snaps 4, such cantilever snaps
4 have space to bounce outward, so that it may smoothly from the inner extraction of cantilever snaps slot 24, thus the effect unlocked in fact.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
Simple automatically lock round plastic water-proof connector of the invention is suitable for various types of electrical connections.
