It withstands, user can not firmly push the second pressing position 4-2；And the first lock pad 5-1 is in the receiving position of the first hammerlock 3, user
The first pressing position 3-2 can firmly be pushed.
When protrusion, 5-4 slides to the second card slot 6-4, by the elastic force of elastic arm 5-3, protrusion 5-4 is caught in the second card slot 6-4
It is interior, it is not easy to slide, the first lock pad 5-1 is located at below the first pressing position 3-2 at this time, and the first pressing position 3-2 pads 5-1 by the first lock
It withstands, user can not firmly push the first pressing position 3-2；And the second lock pad 5-2 is located at except the second pressing position 4-2, uses
Person can firmly push the second pressing position 4-2.
In order to coordinate the slip of protrusion 5-4, the present invention is equal by the entrance slideway of the first card slot 6-3 and the second card slot 6-4
It is designed as ramp structure (not shown).
Pedestal 6 is equipped with guide groove 6-2 with the one side that pin member 5 is affixed；The one side that pin member 5 and pedestal 6 are affixed be equipped with
The fin 5-5 of guide groove 6-2 adaptations.Pin member 5 can be slided along guide groove 6-2, make the protrusion 5-4 of elastic arm 5-3 in support plate
On the first card slot 6-3 and the second card slot 6-4 between slide.
Specifically, pin member 5 is additionally provided with push-and-pull portion 5-6, pin member 5 is pushed to slide convenient for user.
Specifically, latch fitting is set there are two the second hammerlock 4, and two the second hammerlocks 4 are located at 3 both sides of the first hammerlock respectively；Lock pin
Part set there are two respectively correspond to two second hammerlocks 4 the second lock pin 2-2.
Course of work explanation
Define that the first lock pin 2-1 tangles lockhole 3-1, the second lock pin 2-2 is located on the inside of latch hook 4-1, the protrusion 5- of pin member 5
4 original state in the first card slot 6-3 for connector locking.
It should be noted that under this original state, the second lock pad 5-2 is located at below the second pressing position 4-2, the second lock pin
2-2 and latch hook 4-1 is in locking state, can not firmly push the second pressing position 4-2, it is impossible to unlock the second self-locking structure；First
Lock pads 5-1 in the receiving position of the first hammerlock 3, however even if pressing the first pressing position 3-2, since the second self-locking structure is locked, nothing
Method pulls the ' locked ' zone of the first lock pin 2-1 disengaging lockholes 3-1, it is impossible to unlock the first self-locking structure；Therefore, connector is locking
State.
It is unlocked in this original state：
First, the protrusion 5-4 of pin member 5 is slid into from the first card slot 6-3 in the second card slot 6-4, the first 5-1, lock pad
In the lower section of the first pressing position 3-2, the first lock pin 2-1 is still located in lockhole 3-1, it is impossible to unlock the first self-locking structure；And second
Lock pad 5-2 firmly presses the second pressing position 4-2, latch hook 4-1 is made to be tilted around fixing axle except the second pressing position 4-2, the second lock
It sells 2-2 and latch hook 4-1 to be detached from, then pulls out the ' locked ' zone that socket 2 makes the second lock pin 2-2 be detached from latch hook 4-1, complete second
The unlock of self-locking structure.
It should be noted that when pulling out socket 2, due to that cannot unlock the first self-locking structure, the first lock pin 2-1 is still hung
Live in lockhole 3-1, therefore plug 1 and socket 2 are also to maintain the state of connection.
Secondly, the protrusion 5-4 of pin member 5 is slid into from the second card slot 6-4 in the first card slot 6-3, the second lock pad 5-2 exists
The lower section of second pressing position 4-2, the first lock pad 5-1 firmly press the first pressing position 3-2, make lock in the receiving position of the first hammerlock 3
Hole 3-1 is tilted, and the first lock pin 2-1 and lockhole 3-1 is detached from, then pulling out socket 2 makes the first lock pin 2-1 be detached from lockhole 3-1's
' locked ' zone completes unlocking for the first self-locking structure.Plug 1 and socket 2 are completely separable at this time, and connector unlock is completed.
It should be noted that when the unlock for completing the first self-locking structure, protrusion 5-4 is in the second card slot 6-4, the first lock
Pad the lower section that 5-1 is located at the first pressing position 3-2, it is impossible to unlock the first self-locking structure, it is therefore desirable to which protrusion 5-4 is slid into first
In card slot 6-3.When the unlock for completing connector, protrusion 5-4 is attached in the first card slot 6-3 convenient for personnel in next time
Device can be used directly when locking, and such design leads to Joint failure it is possible to prevente effectively from personnel leak operation or operation error
It happens.
During locking：The protrusion 5-4 of pin member 5 is inserted into socket 2 in the first card slot 6-3, by plug 1, presses the first pressing
First lock pin 2-1 is tangled lockhole 3-1 by position 3-2, forms the first self-locking structure of locking；Continue to press on plug 1 and by pin member 5
Protrusion 5-4 slid into the second card slot 6-4 from the first card slot 6-3, press the second pressing position 4-2 and tangle the second lock pin 2-2
Latch hook 4-1 forms the second self-locking structure of locking；Finally the protrusion 5-4 of pin member 5 is slid into the first card slot 6-3.As
Connector and the original state of secondary self-locking device locking.
Compared with prior art, the attainable technique effect of present invention institute includes：Latch fitting is worked in coordination with locking pin member, is formed
Self-locking structure twice, pin member below the first hammerlock and the second hammerlock between slip, by two lock pads in the first hammerlock
With position matching mobile below the second hammerlock, carry out the unlock twice of control connector.During unlock, only first complete primary
The unlock of self-locking structure, and after pin member is resetted, the unlock of secondary self-locking structure could be carried out again.Pin member is simple in structure,
Novel design, can be effectively prevented that personnel leak operation or operation error happens, and improve the self-locking strength of connector, protect
The connection for demonstrate,proving connector is reliable.
In the above-described embodiments, it all emphasizes particularly on different fields to the description of each embodiment, is not described in some embodiment
Part, may refer to the associated description of other embodiment.
The above is the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any ripe
It knows those skilled in the art in the technical scope disclosed by the present invention, various equivalent modifications can be readily occurred in or replaces
It changes, these modifications or substitutions should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with right
It is required that protection domain subject to.
