Description
Technical field
The present invention relates to electric connector fields, and in particular to a kind of connector self-locking structure.
Background technique
Highly reliable locking and quick separating with the complication of connector application environment, to electrical connector plug and socket
It is required that higher and higher.Especially to the reliability of locking, even more more stringent requirements are proposed.It is well known that connector plugs together shape
The lock function of state does not guarantee, directly results in the reliable of connection effect, serious to will cause connector separation failure.
Typical electrical connector can be divided into following several types in the locking that plugs and sockets plugs together under normal circumstances at present：
One, bayonet type：It is very fast that bayonet coupling connector plugs together separating rate.Coupling mechanism force after plugging together is in connection card cap
Waveform spring generates compressing force come what is guaranteed, it is disadvantageous in that：First is that coupling mechanism force is the elastic force that spring generates, it cannot
Accomplish rigid locking；Second is that when having external force or slightly larger plug, socket weight, be easy to appear locking loosely or plug,
The socket depth of parallelism cannot be guaranteed, to influence the reliability of contact.
Two, screw connected：It is general that screw connected connector plugs together separating rate.Coupling mechanism force after plugging together is by connection
Screw fastening clamp force is between nut and socket come what is guaranteed, and locking effect is good when it is connected.Being disadvantageous in that effectively to reach
Screw thread it is anti-loose.Although frictional force when being loosened at present using elastic component and ratchet and method to increase, so
The complexity, manufacturing cost and separating force of product are increased, it is maintainable poor.It is this locking after certain plug number
Release mechanism can generate abrasion and cause the fifth wheel that fails and increase.
Three, straight cutting is plug-type：The plug-type connector of straight cutting is a kind of pellet locking mode after all.It has operation side
Just, feature fast, while not loosened after locking.It is between bayonet type and it is screw connected between a kind of connection
Mode.Shortcoming is after plugs and sockets plugs together locking, because of the presence in the gap of the gap of shell and pellet and locking hole location,
Though cannot disengage, there is opposite shaking and small range axial displacement in plug between inserting, these are all to influence contact contact performance
Hidden danger.
Summary of the invention
After being plugged together present invention aim to address connector in the prior art lock when occur shake, loosen, locking mechanism
It is unreliable, unlock and lock operation are complicated, the deficiency that is not capable of automatic locking, a kind of highly reliable locking is provided, in addition to implementing to unlock
The connector self-locking structure of lock function can be realized when movement automatically.
The technical scheme adopted by the invention is as follows：
A kind of connector self-locking structure, including plug casing, connection inner sleeve and connection exterior nut cap, connection inner sleeve are placed on slotting
The outside of casing, connection exterior nut cap are placed on the outside of connection inner sleeve, and plug casing is equipped with a circle concave spherical surface, connects inner sleeve
It is equipped with more than one stepped hole, each stepped hole is located on same circumference, and stepped hole is through-hole, stepped hole and concave spherical surface
Position is corresponding, is equipped with pellet in stepped hole, and the diameter of pellet is less than the internal diameter of stepped hole, pellet in stepped hole freely up and down
Move and with concave mating spherical surfaces；It is additionally provided with a pair of of spring retainer key on connection outer wall of inside race, the spring retainer key is parallel to
The axis of inner sleeve is connected, main spring is installed between two spring retainer keys；It is described connection exterior nut cap inner wall be equipped with one with
On pellet positive stop lug boss and a positioning key, pellet positive stop lug boss quantity and position with the stepped hole pair that connect inner sleeve
It answers, pellet positive stop lug boss limits the pellet in pellet stepped hole, and positioning key is parallel to the bus of 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
Through-hole, blind hole are position on the contrary, blind hole opening is towards outside on key, and the main spring is open annular reed, split ring
Blind hole is fixed in one end of shape reed, and the other end of open annular reed passes freely through through-hole.
Further, it is provided with spring division slot on the connection outer wall of inside race, the spring division slot is to main spring
Axial limiting.
Further, the head outer wall of the plug casing is equipped with the first circlip groove, and connection exterior nut cap end face is equipped with the
Two circlip grooves, retaining ring is equipped in first circlip groove, and retaining ring and the cooperation of the second circlip groove limit.
Still 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 connecting exterior nut cap not by external force, even
The two sides for connecing the positioning key on exterior nut cap are limited by spring on interior set is connected respectively, connection exterior nut cap with connect inner sleeve position phase
To fixation.Pellet is pressed into connection inner sleeve pellet stepped hole and plug casing spill by the pellet limiting stand connected in exterior nut cap at this time
In spherical surface, makes to connect inner sleeve and plug casing reaches lock state.Unlock（External force screws separation）When, connection exterior nut cap with connect
Inner sleeve relatively rotates, while squeezing the main spring of side, and the pellet limiting stand for connecting exterior nut cap leaves the upper of pellet stepped hole
Side contacts the extruding to pellet, at this point, there is larger space Free up Memory between connection exterior nut cap and pellet stepped hole, pellet can be certainly
By up and down and relieve locking, plug casing is relatively rotated with inner sleeve is connect, and implements unlock.Once unlocking motion stops,
Under the action of the spring, connection exterior nut cap returns to and connect the position fixed position relative of inner sleeve, while realizing locking.As a result,
, it can be achieved that plug casing is relatively rotated with inner sleeve is connect when this structure is in addition to implementation unlocking motion, it may achieve connector plug, insert
The separating effect of seat；In other situations, lock function can be realized automatically.To reach the highly reliable locking of connector and quickly divide
From purpose.The processing of this structure is simple, easy to operate, high efficient and reliable.
