The shaking of the plug is the inevitable result of the internal structure of this type of socket. It is the elastic copper sheet in the socket that is in contact with the plug of the plug, and the elastic copper sheet can only be on the two sides that are in contact with the plug. There is a certain resistance effect on the upper surface, but there is no blocking effect in the direction of the other two surfaces, and the plug will be easier to shake and loosen in this direction.

Embodiment
[0039] combine Figure 1 to Figure 4 As shown, this embodiment takes a three-pin plug and a three-hole socket compatible with the three-pin plug as an example to further illustrate the anti-loosening principle of the present invention.
[0040] An anti-loosening power connection device in this embodiment includes a plug 1 and a socket 2 adapted to the plug 1, wherein the plug 1 is provided with a pin 12 and a plug anti-off part on the insertion surface 11 13. The pin 12 can be a flat pin or a round pin, and at least one vertical surface is provided on the plug anti-off part 13; the panel 21 of the socket 2 is provided with a jack 22 and a socket anti-off part 23, the jack 22 is adapted to the above-mentioned pin 12, and at least one vertical surface is provided on the anti-falling part 23 of the socket. The above-mentioned plug anti-off part 13 and socket anti-off part 23 are concave-convex mated along the insertion and extraction direction of the plug 1 on the socket 2. In t...

The invention discloses an anti-release power supply connection apparatus and a plug and a socket of the power supply connection apparatus, and belongs to the technical field of power supply connection. The anti-release power supply connection apparatus comprises the plug and the socket; a plug anti-release part is arranged on the connection surface of the plug; a socket anti-release part is arranged on a panel of the socket; the plug anti-release part and the socket anti-release part are matched in a concave-convex plugging manner in a plug-pull direction of the plug; the plug anti-release part and the socket anti-release part are provided with at least one pair of clearance-fit vertical surfaces; the clearance-fit vertical surfaces form turning interference when the plug turns by taking one side as a supporting point to block the plug so as to enable the lifting height of the plug to be limited within a certain range, so that the plug cannot drop from the socket. The invention also discloses the anti-release plug and socket. The problem that the plug is easy to loosen and drop is solved fundamentally without affecting the rapid plug-pull of the plug; and in addition, the anti-release power supply connection apparatus, and the plug and the socket are simple in structure, convenient to manufacture and wide in popularization and application prospects.
Description
technical field [0001] The present invention relates to an electrical connection device and its plug and socket, more specifically, to a loose-proof power connection device and its plug and socket. Background technique [0002] Most of the power connection devices used in daily life are two-hole or three-hole power plugs and sockets (blade plugs and sockets), which are the most widely used electrical accessories. The advantages of the two-hole and three-hole power plugs and sockets are that they are plug-and-play, easy to use, simple in structure, and low in price. However, the connection stability between the plug and the socket is relatively poor. During daily use, the plug is easy to fall off from the socket when pulled by an external force, which brings potential safety hazards and even electricity accidents. [0003] In order to solve the problem that the plug of the above-mentioned power connection device is easy to fall off, many anti-falling plugs and sockets have a...
