nullIn the specific embodiment that the application provides，The plug of adapter、Unitor includes the first spigot 13 and coordinates the second spigot of interfix with it，The first contact sets 15 it is provided with in first spigot 13，The second contact sets 14 for being connected it is provided with the first contact sets 15 in second spigot，Multiple contact array is had in first contact sets 15，It is arranged in definite shape，And also have multiple contact array in the second contact sets 14，It is arranged in the shape identical with the first contact sets 15，So as corresponding plug-in mounting，Concept used here as contact sets，Substantially，Only one of which contact is also possible，But the most there is not the alignment issues of the technical program in man-to-man contact，So the contact that normal condition is multi-to-multi connects，And this connection has strict demand，The correspondence of contact can not wrong plug，Otherwise signal can not transmit correctly.

First spigot 13 outside wall surface is provided with the first labelling, second spigot includes the matrix 12 fixing the second contact sets 14 and is arranged at the sheath body 11 of matrix 12 outer ring, sheath body 11 outside wall surface makes the second labelling that the second contact sets 14 coordinates with the first correct plug-in mounting of contact sets 15 when being provided with the first label alignment, sheath body 11 rotates predetermined angular after being sleeved on the first spigot 13 and the first spigot 13 locks, after rotating predetermined angular, first labelling and the second labelling no longer align, but, spinning reduction parts it are additionally provided with in sheath body 11, when unlocking sheath body 11, spinning reduction parts drive the second labelling on sheath body 11 to reply initial position, realign with the first labelling.Substantially, when first spigot 13 separates with the second spigot, the first labelling and the second labelling are not fixed relative to position, and the two alignment mentioned here each means that the two is when closing on the state of plug-in mounting, in order to ensure to make the first contact sets 15 be correctly inserted into the second contact sets 14, the two is made to align.

In sum, the first spigot 13 and the second spigot are when mutual plug-in mounting, as long as making the second label alignment on the first labelling and sheath body 11 correctly to assemble, rotate sheath body 11 after plug-in mounting, it is achieved the first spigot 13 and the interlocking of the second spigot.After releasing plug-in mounting, owing to being provided with the spinning reduction parts making it reset in sheath body 11, sheath body 11 recoils to original state, when plug-in mounting next time, as long as the second labelling on sheath body 11 and the first label alignment, the first spigot 13 is the most corresponding with the position of the first contact sets 15 in the second spigot and the second contact sets 14, can readily realize plug-in mounting, use this technical scheme, it is achieved that provide a kind of and be prone to the plug of plug-in mounting para-position, socket connecting structure.

In another specific embodiment of the application, spinning reduction parts are torsionspring, the elastic direction of torsionspring is circumferentially, this torsionspring is used for providing restoring force, torsionspring two ends connect sheath body 11 and matrix 12 respectively, and torsionspring is under non-stress, the first labelling is positioned at initial position and the second label alignment.It should be noted that suitable specification to be selected by this torsionspring, it is to avoid its rotation elasticity is too small to such an extent as to reset inaccuracy, causes the first labelling and the second labelling not to align, and rotation elasticity to be avoided is excessive, affect the locking after sheath body 11 reverses.

Further, sheath body 11 uses two-section separated structure, including outer ring sleeve and the inner ring sleeve being close to the setting of its inwall, and the two fixing connection, torsionspring external diameter is equal to outer ring sleeve diameter and is set in inner ring sleeve rear end, and outer ring sleeve tube rear end stretches out the rear end of inner ring sleeve torsionspring.So design, is equivalent to be fixed on torsionspring in one groove of inner ring sleeve rear end, protects torsionspring, it is to avoid it is wiped with miscellaneous part and touches, and this design greatly reduces the fault rate of torsionspring in actual applications, also reduces the fault rate of adapter.Inner ring sleeve and outer ring sleeve split design, reduce manufacture difficulty, be equivalent to form parts is divided into two cylindrical structures, it is easier to processing.

In another specific embodiment of the application, also include the first circumferentially positioned parts being arranged on the first spigot 13 and be arranged on matrix 12 the second circumference positioning element for coordinating location with the first circumferentially positioned parts.The first labelling and the second labelling is positioned iff relying on naked eyes, although can be with plug-in mounting, but the feel of plug-in mounting is bad, the first contact sets 15 can only be relied on to close the second contact sets 14 self coordinate, if and the contact that comprises in the first contact sets 15 is too much, or puzzlement can be caused in location, so arranging a pair further on the first spigot 13 and on the matrix 12 of the second spigot for the first circumferentially positioned parts coordinating guiding and the second circumference positioning element, guided by both, can easier plug-in mounting, feel is more preferable, and people can experience the feel of importing.In first circumferentially positioned parts and the second circumference positioning element, one is key, and another one is keyway.Use the mode that keyway coordinates with key, it is possible to especially optimize plug-in mounting feel.
