Detailed Description

A self-locking plug 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 6, the embodiment described with reference to the drawings is exemplary, and the embodiment of the present invention is described below in detail.

As shown in fig. 1 to 6, the self-locking plug 100 includes: insulating housing 10, a plurality of inserted sheets 20 and at least one driving piece 30, insulating housing 10 has good insulating properties, can guarantee that there is sufficient insulation resistance between electrified part and the easy part that is touched by the people, and have the ability of nai higher voltage impact, can guarantee insulating housing 10's security, a plurality of inserted sheets 20 all set up in insulating housing 10, and a plurality of inserted sheets 20 interval distribution on insulating housing 10, can guarantee like this that there are certain creepage distance and electric clearance between a plurality of inserted sheets 20, make possess sufficient safe distance between the auto-lock plug 100, the phenomenon of short circuit can not appear. It should be noted that the number of the insert pieces 20 may be two or more.

Specifically, as shown in fig. 1, each self-locking plug 100 includes: the extension part 21 and the extension part 22 are sequentially distributed in the length direction, the extension part 21 extends into the insulating shell 10, the extension part 22 extends out of the insulating shell 10, and when the self-locking plug 100 is connected with a socket, the extension part 22 extends into the socket. The extension 22 is used for connecting with the spring plate in the socket, and the extension 21 is used for mounting the insert 20 on the insulating housing 10.

As shown in fig. 1 and 4, the end of the extension portion 22 of at least one blade 20 is further provided with a locking portion 221 protruding inward, the number of blades 20 having the locking portion 221 can be one or two, when only one or two locking portions 221 are provided on the extension portion 22 of the blade 20 on the self-locking plug 100, the blade 20 on the self-locking plug 100 can be fixed on the socket through the locking portion 221, and the locking portion 221 can be in locking fit with the spring leaf in the socket, so that the connection stability between the self-locking plug 100 and the socket can be ensured.

As shown in fig. 1 and 4, at least one driving member 30 is disposed in the insulating housing 10, the driving member 30 is used for driving the extending portion 21 to move towards the inside, and when the self-locking plug 100 needs to be separated from the socket, the driving member 30 drives the extending portion 21 to move towards the inside, so as to drive the extending portion 22 of the insertion piece 20 of the self-locking plug 100 to move towards the outside, and further separate the locking portion 221 from the socket, so that the self-locking plug 100 can be conveniently pulled out from the socket. It will be appreciated that the movement of the blades 20 relative to the housing 10 uses the principle of leverage, and when the user drives the end of the protrusion 21 to move inward via the driving member 30, the end of the protrusion 22 will move outward, so as to complete the unlocking and facilitate the separation of the self-locking plug 100 from the socket.

Therefore, when the self-locking plug 100 is inserted into a socket, the locking part 221 on the end part of the extending part 22 of the insertion sheet 20 can be in clamping fit with a reed in the socket, so that the connection between the self-locking plug 100 and the socket is more stable, and the self-locking plug cannot be separated under the action of external force; when the self-locking plug 100 needs to be separated from the socket, a user can drive the extending part 21 to move towards the inner side through the driving part 30, so that the extending part 22 moves towards the outer side, namely the locking part 221 and the extending part 22 move towards the outer side together, the locking part 221 and the reed of the socket are released from the clamping locking relation, the self-locking plug 100 and the socket can be conveniently separated, the self-locking plug 100 can be easily pulled out of the socket, and the connection stability and the safety between the self-locking plug 100 and the socket can be improved.
