In the practical work of the plug and the socket, two states of insertion and separation are mainly adopted, and the two states are as follows:
and insertion and state:
before plugging, the bumping post 34 on the socket is pushed downwards forcibly, and is locked by a locking mechanism formed by a first sleeve 40 and a third steel ball 43 on the socket, and at the moment, a spring on the bumping post 34 stores energy; during insertion, the hand wheel body 19 is rotated anticlockwise firstly to enable the plug connecting mechanism to extend out to align with the mark groove on the head seat shell, the rib grooves on the head seat shell are matched, the plug is pushed to the socket by force, a click sound is heard, the steel ball on the plug connecting mechanism is pushed into the groove of the socket lock sleeve 33 by the pull rod at the moment to realize the locking of the head seat, the hand wheel is rotated clockwise, the insertion and combination force generated by the torque conversion of the hand wheel overcomes the insertion and combination resistance (pinhole friction force, movable layer reset spring force and shell friction force) between the head seats, the plug and the socket are inserted and combined in place, and the separation spring between the plug and the socket stores energy at the moment.
A separation state:
when the mechanical separation is carried out, the pull rod 32 is pulled, the diameter section of the pull rod 32 can move to the position below the steel ball, the first steel ball 1 moves towards the inside of the connecting sleeve 25, when the outer diameter of the steel ball is lower than the end face of the connecting sleeve 25, the lock sleeve 33 is not limited by the first steel ball 1, the connecting mechanism is unlocked, and the headstock separation is realized under the action of the separation spring;
when the electricity is separated, an electromagnet coil 44 on the socket is electrified to generate electromagnetic force, the locking mechanism of the socket is unlocked through the attraction of an armature 42, the impact column 34 moves leftwards under the action of an energy storage spring and pushes the pull rod 32 to move till the end face of the pull rod 32 is pushed to the end face of the connecting sleeve 25, and at the moment, the end faces of the impact column 34, the pull rod 32 and the connecting sleeve 25 are flush; meanwhile, the diameter section of the pull rod 32 moves below the first steel ball 1, the first steel ball 1 moves towards the inside of the connecting sleeve 25, when the outer diameter of the first steel ball 1 is lower than the end face of the connecting sleeve 25, the lock sleeve 33 is not limited by the steel ball, the connecting mechanism is unlocked, and the headstock separation is realized under the action of the fourth spring 30 of the plug.
In addition, the socket has a flame-proof characteristic, which is achieved by the flame-proof plate 60, which, when the flame-proof plate 60 is compressed, overcomes the action of the fifth spring 37, and gradually approaches the socket insulator, completing the conduction function. When the socket is separated, the flame-proof plate 60 and the socket insulating plate 55 are always in an open circuit state, and the short circuit-proof and flame-proof functions can be achieved.
Those skilled in the art will appreciate that those matters not described in detail in the present specification are well known in the art.
