Description
Technical field
The present invention relates to electric connector field, and in particular to a kind of adapter self-locking structure.
Background technology
With the complication of adapter applied environment, the highly reliable locking and sharp separation to electrical connector plug and socket
Require more and more higher.Especially to the reliability for locking, even more put forward higher requirement.It is well known that adapter plugs together shape
The lock function of state does not ensure that directly result in the reliability of connection effect, serious meeting causes adapter to separate failure.
Typical electrical connector can generally be divided into following several types in the locking that plugs and sockets is plugged together at present：
First, bayonet type：It is very fast that bayonet coupling connector plugs together separating rate.Coupling mechanism force after plugging together is by connecting the waveform in card cap
Spring produces compression stress come what is ensured, and it is disadvantageous in that：One be coupling mechanism force be spring produce elastic force, it is impossible to accomplish
Rigid locking；Two when being have external force effect or slightly larger plug, socket weight, locking easily occurs loosely or plug, socket
The depth of parallelism it cannot be guaranteed that, so as to affect the reliability of contact.
2nd, it is screw connected：It is general that screw connected adapter plugs together separating rate.Coupling mechanism force after plugging together is by connection
Between nut and socket, come what is ensured, when it connects, locking effect is good for screw fastening clamp force.It is disadvantageous in that and effectively can not reaches
Screw thread it is anti-loose.Although employing elastic component and ratchet and method at present to increase frictional force when releasing, so
Complexity, manufacturing cost and the separating force of product is increased, it is maintainable poor.It is after certain plug number of times, this locking
Release mechanism can produce abrasion and cause to fail and increase fifth wheel.
3rd, straight cutting is plug-type：The plug-type adapter of straight cutting is a kind of pellet locking mode after all.It has operation side
Just, quick the characteristics of, while not releasing after locking.It is between bayonet type and it is screw connected between a kind of connection
Mode.Weak point is after plugs and sockets plugs together locking, because the presence in the gap of housing and pellet and the gap of locking hole position,
Though can not disengage, presence between plug is inserted is rocked and small range axial displacement relatively, and these are all to affect contact contact performance
Hidden danger.
The content of the invention
Present invention aim to address occur rocking when locking after adapter is plugged together in prior art, release, locking mechanism
Unreliable, unblock and lock operation complexity, the deficiency that can not be locked automatically, there is provided a kind of highly reliable locking, except implementing unblock
The adapter self-locking structure of lock function can be automatically obtained during action.
The technical scheme that the present invention takes is：
A kind of adapter self-locking structure, including plug casing, connection inner sleeve and connection exterior nut cap, connection inner sleeve are placed on jack shell
The outside of body, connects the outside that exterior nut cap is placed on connection inner sleeve, and plug casing is provided with a circle matrix sphere, puts and set in connection
There is more than one stepped hole, each stepped hole is located on same circumference, stepped hole is the position of through hole, stepped hole and matrix sphere
Correspondence, is provided with pellet in stepped hole, the diameter of pellet is less than the internal diameter of stepped hole, and pellet is freely up and down moved in stepped hole
And with matrix mating spherical surfaces；A pair of spring retainer keys are provided with connection outer wall of inside race also, the spring retainer key is parallel to even
The axis of inner sleeve is connect, main spring is installed between two spring retainer keys；The inwall of the connection exterior nut cap is provided with more than one
Pellet positive stop lug boss and a positioning key, pellet positive stop lug boss quantity and position with the stepped hole pair for being connected inner sleeve
Should, pellet positive stop lug boss is spacing to the pellet in pellet stepped hole, bus of the positioning key parallel to connection exterior nut cap, positions key mapping
Between two spring retainer keys.
Further, respectively at least provided with a through hole and a blind hole, two spring retainers on each spring retainer key
Lead on key, blind hole be position conversely, blind hole opening is towards outside, the main spring is open annular reed, open annular
Blind hole is fixed in one end of reed, and the other end of open annular reed passes freely through through hole.
Further, spring division groove is provided with the connection outer wall of inside race, the spring division groove is to main spring
Axial limiting.
Further, the head outer wall of the plug casing is provided with the first circlip groove, and outer attachment cap end face is provided with second
Circlip groove, described being provided with the first circlip groove are provided with back-up ring, and back-up ring coordinates spacing with the second circlip groove.
Yet further, the free end of the open annular reed pushes against the side of positioning key.
After taking above technical scheme, beneficial effects of the present invention are：In the case where connection exterior nut cap does not receive external force, even
The both sides for connecing the positioning key on exterior nut cap are limited by the spring put in connecting respectively, are connected exterior nut cap and are connected inner sleeve position phase
To fixation.Pellet press-in is connected inner sleeve pellet stepped hole and plug casing spill by the pellet limiting stand now connected in exterior nut cap
In sphere, connection inner sleeve is made to reach lock-out state with plug casing.Unblock（External force screws separation）When, connect exterior nut cap and be connected
Inner sleeve is relatively rotated, while extruding the main spring of side, the pellet limiting stand for connecting exterior nut cap leaves the upper of pellet stepped hole
Side, contacts the extruding to pellet, now, has larger space Free up Memory between connection exterior nut cap and pellet stepped hole, and pellet can be certainly
By up and down and relieve locking, plug casing be connected inner sleeve relative rotation, implement unblock.Once unlocking motion stops,
Under the action of the spring, connect exterior nut cap to return to and the position fixed position relative for being connected inner sleeve, while realizing locking.Thus,
Except implementing during unlocking motion, achievable plug casing is relatively rotated this structure with inner sleeve is connected, and be may achieve connector plug, is inserted
The separating effect of seat；In the case of other, lock function can be automatically obtained.So as to reach the highly reliable locking of adapter and quick point
From purpose.The processing of this structure is simple, easy to operate, high efficient and reliable.
