Description of rapid plug-in and rapid release:

as shown in fig. 17-19, when the plug latch 5 is in a natural state, the protrusion 5-1 thereof extends into the cavity of the first insulating housing 1, and when the plug is inserted into the socket, the plug latch 5 contacts the second insulating housing 01 of the socket, the plug latch 5 retracts the compression spring 6 to retract the plug latch 5 into the first insulating housing 1, and the plug latch 5 is in a pressed state as shown in fig. 18. Because the inclined surface 5-2 characteristic of the locking piece 5 in the plug contacts with the inclined surface characteristic 01-6 of the locking structure 01-6 of the second insulating shell 01 of the socket first, the plug can be easily inserted into the socket, and when the inner end surface 1-6 characteristic of the first insulating shell 1 of the plug is tightly attached to the end part 1-8 characteristic of the second insulating shell 01 of the socket, the plug is completely inserted. After full insertion, catch member 5 returns to its natural state.

Comparing with the plug and socket shown in fig. 19, before the plug and socket are inserted into each other, as shown in fig. 20, after the insertion is completed, when the plug locking member 5 returns to the natural state, the end surface of the protrusion 5-1 of the plug locking member 5 interferes with the feature of the locking structure 01-7 of the second insulating housing 01 of the socket, so that the plug cannot be withdrawn backwards, and the feature of the inner end surface 1-6 of the first insulating housing 1 of the plug is matched with the feature of the end part 01-8 of the second insulating housing 01 of the socket, so that the plug can be prevented from being inserted forwards, and thus the plug and the socket can be ensured to be connected firmly and can be inserted quickly.

When the plug and the socket need to be loosened, the plug locking piece 5 only needs to be pressed down to retreat into the first insulating shell 1, the end face of the protrusion 5-1 of the plug locking piece 5 has no interference with the characteristic of the locking structure 01-7 of the second insulating shell 01 of the socket, and the plug can easily and freely retreat from the socket. Therefore, the plug and the socket can be quickly plugged and pulled out, and are fixed and reliable when being inserted.
