In the locking process, because the locking steel ball does not block the mandrel after entering the locking groove, the mandrel 306 moves downwards under the action of the mandrel spring and drives the cover plate 308 to move downwards along with the mandrel spring so as to press down the insulating sliding sleeve 402, then the insulating sliding sleeve 402 drives the short circuit contact pin arranged in the insulating sliding sleeve to press down, at this time, the locking identification device moves to the state shown in fig. 9, the locking mechanism is in the locking state, the two short circuit contact pins 403 are respectively inserted into the two corresponding jacks 406, the conduction between the two jacks 406 is realized, the conduction signal is led out to the corresponding signal receiving system to serve as an identification signal, the situation that the plug and the socket are inserted in place at this time can be clearly judged, and at this time, the plug contact part and the.
In the process of upward movement of the socket and insertion of the plug, the plug is pushed upwards, so that the plug shell moves upwards to abut against the lower surface of the floating plate, and the floating springs on the two sides of the floating plate are elastically pushed by the supporting cylinder and the mounting plate to play a role in buffering during insertion. The plug and the socket are completely inserted in place to form a state as shown in fig. 9, at the moment, the plug shell can realize radial floating relative to the floating plate, the plug shell and the floating plate can float up and down relative to the mounting plate along the axial direction, and the floating spring is further compressed when floating upwards, so that the connector can be ensured to work under the high-frequency vibration environment after being locked, and can also adapt to mounting errors.
When the plug and the socket are required to be separated, the socket is driven to move downwards by a mechanical structure or an electric structure, the socket can also drive the plug to move downwards for a short distance, but the cover plate is firstly contacted with the floating plate and is in blocking fit with the floating plate, the cover plate pulls the mandrel to move upwards relative to the plug shell under the blocking action of the floating plate until the locking steel balls are extruded into the radial through holes of the mandrel sleeve, the locking mechanism completes unlocking, the plug returns to the state shown in fig. 5, the insulating sliding sleeve 402 moves upwards by the reset force generated by the spring 404 at the moment, the two short circuit contact pins 403 are separated from the corresponding jacks 406, the two jacks are in an open circuit state, and the locking mechanism is restored and can be used for the next. Because the floating plate moves the mandrel upwards relative to the plug shell in the process of separating the plug from the socket, the whole separation process does not need manual intervention (the existing falling connector needs to manually pull the mandrel to unlock the locking mechanism), the method is suitable for automatic operation of the connector in a hidden place, and the automation level of the whole equipment can be obviously improved.
In other embodiments, the locking mechanism can also be installed at the socket end, and then the locking identification device is also installed at the socket end, and the locking ring is installed at the plug end; the locking identification device is not limited to be applied to the field of falling-off connectors, and the insulating sliding sleeve can be directly or connected with action or execution components (such as a pull rod, a mandrel, a locking pin and the like) of a locking mechanism in other types of connectors to realize synchronous motion, so that the locking state of the connector can be definitely judged.
The above description is only a preferred embodiment of the present invention, and any person skilled in the art can make any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the present invention without departing from the scope of the present invention, and still fall within the scope of the present invention.
