A kind of plug-type electric connector with secondary locking, it comprises plug, socket and adapter sleeve, described plug comprises plug casing, described plug casing arranges a raised step, described plug casing surface arranges " L " connected in star, should axially extend to raised step from plug casing one end by " L " connected in star, bending one end of described " L " connected in star is positioned at raised step place, and the plug casing surface between described plug casing one end and raised step also arranges a ring annular groove; Described plug arranges adapter sleeve, and described adapter sleeve is enclosed within plug casing, arranges spring between described adapter sleeve and plug casing, and described adapter sleeve is arranged the convex tendon being used for coordinating with " L " connected in star.
In order to realize the present invention better, further technical scheme is:
According to one embodiment of the invention, described plug casing is aluminium alloy.
The present invention can also be:
According to one embodiment of the invention, described plug casing arranges insulating base, and described insulating base is modification of nylon.
Compared with prior art, one of beneficial effect of the present invention is:
A kind of plug-type electric connector with secondary locking of the present invention, it cannot disconnect in unartificial situation, even if plug-type connector is under vibration at high speed and impact condition, plug and socket is also not easy to be separated, thus reduces the generation of security incident.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
As shown in Figure 1, Figure 2 and Figure 3, a kind of plug-type electric connector with secondary locking, it comprises plug 1, socket 2 and adapter sleeve 3, described plug 1 comprises plug casing 5, described plug casing 5 arranges a raised step 51, described plug casing 5 surface arranges " L " connected in star 6, raised step 51 should be axially extended to by " L " connected in star 6 from plug casing 5 one end, bending one end 61 of described " L " connected in star 6 is positioned at raised step 51 place, and plug casing 5 surface between described plug casing 5 one end and raised step 51 also arranges a ring annular groove 52; Described plug 1 arranges adapter sleeve 3, and described adapter sleeve 3 is enclosed within plug casing 5, arranges spring 7 between described adapter sleeve 3 and plug casing 5, and described adapter sleeve 3 is arranged the convex tendon 4 being used for coordinating with " L " connected in star 6.
Described plug casing 5 is aluminium alloy, by aluminium alloy extruded technological forming.
Described plug casing 5 arranges insulating base, and described insulating base is modification of nylon, by plastic pressure forming.
In sum, plug-type electric connector after improvement can realize the function of general plug-type electric connector, and in case of need, can by the plug 1 of electric connector and socket 2 locked, prevent accidental release, only when artificial, electric connector could be disconnected, reach and avoid electric connector in unartificial situation, abnormal disconnection.
Its plug 1 of described electric connector can by simply promoting to achieve a butt joint with pulling and be separated with socket 2; The convex tendon 4 that described electric connector is arranged, " L " connected in star 6 and annular groove 52, described convex tendon 4 can slide on " L " connected in star 6, and turns an angle, and realizes secondary locking function.
When not needing secondary locking function, it is identical with general plug-type electric connector, when plug 1 is connected with socket 2, needs plug 1 alignment socket 2 to push, and when disconnection, holding adapter sleeve 3 can exit plug 1.
When needs secondary locking function, after plug 1 is pushed socket 2, can by the adapter sleeve 3 on plug 1 to right rotation, convex tendon 4 on adapter sleeve 3 moves in " L " connected in star 6 on plug casing 5, and final position is arrived after rotation 30 degree, at this moment just cannot disconnect connector according to a conventional method again; When needing disconnect connector, adapter sleeve 3 is rotated to final position left, then operate according to the disconnect mode of general plug-type connector.
Consider the spring 7 of connector inside, there is interaction force when connector secondary locking in adapter sleeve 3 and plug casing 5, finally converts frictional force to, avoids adapter sleeve 3 and plug casing 5 mutually to rotate, cause secondary locking to lose efficacy.
