For the connector plug of the present invention when screwing clockwise, coupling nut can drive latch segment to rotate, in the mistake screwed
Latch segment front-rear reciprocation movement on the slope of splines shell locking slot under the collective effect of spring and coupling nut in journey, no
It can influence to screw.Once reversely rotating, latch segment can be absorbed on the locking face of slope bottom, since latch segment and splines shell are equal
For metal material (rigid material), and latch segment is without the external force for moving up and (being detached from splines shell locking slot), therefore keeps lock
Locking structure stablizes locking.
It only needs to push latch segment to direction is plugged together when needing to loosen, you can unlock is normal to detach.
Beneficial effects of the present invention：
Solve the problems, such as that thread locking structure connector locking effect is bad, locking mode is troublesome in poeration and inconvenient for use,
It realizes the fast insert-pull of thread locking structure connector by the present invention program and stablizes and lock, broadening screw thread coupling is applicable in model
It encloses, more broad electric interfaces selection is provided for military domain.

Specific embodiment
A kind of connector plug of threaded retaining mechanism, structure chart 1, Fig. 2 and Fig. 3, plug include electric contact piece 1, absolutely
Edge body 2, coupling nut 3, spring 4, latch segment 5, splines shell 6, fixing nut 7, attachment 8.Plug, insulator and splines shell
Using separate structure, insulator is plastic material, it is ensured that insulation as defined in being kept between electric contact piece and pressure-resistant performance connect spiral shell
Locking mechanism is collectively formed in cap, latch segment, spring, splines shell and the screw thread of plug is attached, and then passes through fixing nut
It is fixed.
The nut that connects is fixed together with latch segment, on step of the spring one end loaded on coupling nut, the other end
The end of facing directly of latch segment protrusion block is resisted against, the inclined-plane of latch segment protrusion block coordinates with the inclined-plane of splines shell locking slot,
Splines shell is connected by screw thread with coupling nut, and the locking slot that splines shell is caught in by latch segment realizes locking, connects spiral shell
Locking mechanism is collectively formed in cap, latch segment, spring, splines shell and the screw thread of plug is attached, coupling nut, latch segment,
Locking mechanism is collectively formed when being screwed with socket for spring, splines shell and normal threaded pin is consistent, upon connection, locking
Structure ensures that coupling nut will not reversely rotate, so as to keep the stabilization of locking mechanism by the hardness locking of latch segment.
Threaded connection section is equipped with outside the splines shell, splines shell is circumferentially equipped with locking slot, the slot bottom of locking slot
To notch in inclined-plane ramped shaped, section is right angle, and concrete structure is as shown in Figure 8.
The coupling nut is by screw thread on splines shell, and coupling nut top is equipped with the limiting slot of rectangle, in square
Shape trench bottom is equipped with oval guide groove, shown in concrete structure as Fig. 4 and Fig. 5.
The latch segment is size step plane shape, and small stair is located at the center of big step, at the side center of small stair
Equipped with connecting hole, block that opposite side is conformed with, the block side takes the form of inclined plane, and corresponding opposite side is faces directly, specifically
Shown in structure as Fig. 6 and Fig. 7.
The big step of the latch segment is in the limiting slot of coupling nut, and the block of protrusion is pressed in spline shell by spring
In the locking slot of body.
Locking mechanism is collectively formed when being screwed with socket and normal spiral shell in coupling nut, latch segment, spring, splines shell
Line plug is consistent, and upon connection, locking mechanism ensures that coupling nut will not reversely rotate and protect by the hardness locking of latch segment
Hold the stabilization of locking mechanism.
As shown in Fig. 2, Fig. 3 and 9, the top small stair of latch segment is in the limiting slot of coupling nut, what lower part protruded
Block is in the locking slot of splines shell, and the effect of spring is that (have at the rear portion that latch segment is pressed in splines shell locking slot tiltedly
The part on slope), the effect of fixing nut is that latch segment is limited, and avoids.When screwing clockwise, coupling nut meeting
Latch segment rotation is driven, latch segment is locked under the collective effect of spring and coupling nut in splines shell during screwing
Front-rear reciprocation movement on the slope of slot, does not interfere with and screws.Once reversely rotating, it is oblique that latch segment can be absorbed in splines shell locking slot
On the locking face in bottom of slope portion, since latch segment and splines shell are metal material (rigid material), and latch segment is undirected moves up
The external force of dynamic (being detached from splines shell locking slot) so unless destroyed, otherwise can not move, so also just limitation connection spiral shell
Cap can not reversely rotate, so as to fulfill the locking of connector.
If you need to unlock separation, then latch segment to plug-connection section is pushed with hand, be pushed into the limiting slot of coupling nut, once lock
Tight block enters in slot, and the block that its underpart protrudes will be deviate from from the locking slot of splines shell, it is impossible to limit again, coupling nut can
With free reverse rotation, the lock release of connector plug is normal to detach.
By the innovation of more than structure design, the connector plug is made to ensure good locking property, locking effect is good,
It is easy to use.
