Description
Technical field
The present invention relates to a kind of arrangements of electric connection and its socket and plug, more specifically to a kind of rotary self-locking formula
Directly pull out arrangements of electric connection and its socket and plug.
Background technology
Traditional arrangements of electric connection typically uses card edge type, such as common holes, three hole plug and sockets, plug
Insertion socket is to be powered, and it is power-off that plug extracts socket.This traditional electric connection mode although use it is very convenient, but its
Electrical connection fully relies on the resilience contact of hard contact and electric conductivity is completed, and hard contact must simultaneously have conductive and clamping
, in actual use, often there are the phenomenons such as loosening or virtual connection in function, and the reliability of electrical connection is poor；Additionally, this electrical connection
Mode easily produces electric spark in plug swapping process, and serious even can cause to use electrification.Further, traditional plug gold
More long, not only waste of materials is exposed in category contact, and the potential safety hazard such as can also be caused to get an electric shock, and in transit, metal more long is touched
Put also easy bending and influence normally to use.
Lack in order to the electrical connection of the plug and socket for overcoming above-mentioned tradition direct insertion is dangerous, reliability of electrical connection is poor etc.
Point, occurs in that some new plug and sockets on the market, also changes existing electric connection mode.Especially as rotation plug
And socket, it is inserted in round-meshed socket by by circular plug of the outer wall with hard contact, and is passed through
The contacting for making plug and socket is rotated by 90 °, plug generally there are two kinds of situations with the extraction of socket, and one kind is to reversely rotate
Plug simultaneously ejects plug, but this extraction mode, and in case of emergency, power-off speed is slower, there is certain safety
Hidden danger；Another kind can be directly pulled the plug out of the socket on on-position, but due to the latch-up structure in this arrangements of electric connection not
Enough stabilizations, to plug-locking pine or tension excessively, cause using inconvenience, and are generally required on the socket panel of this electrical connection and set
Two breach are put, one is used to insert plug, and one is used to pull the plug out of the socket, and causes user's frequent wrong plug when plug is inserted, behaviour
Make relatively complicated.
The content of the invention
1. the invention technical problem to be solved
It is an object of the invention to overcome existing rotary type electric connection device to cause because of energization locking mechanism stability difference
Unstable, the awkward deficiency of electrical connection, there is provided a kind of rotary self-locking formula directly pulls out arrangements of electric connection and its socket and plug, adopts
With technical scheme, it is engaged from lock section from lock section and plug using the socket of simple structure, in plug by inserting position
Put when inserting and rotating to on-position, self-locking action can be formed, force is easy to during rotation, it is easy to use, and self-locking action
It is reliable and stable, it is ensured that electrical connection stabilization；And plug directly can be extracted directly on on-position, without cumbersome reverse rotation
Extract, power-off is more quick, and security is more preferable；Meanwhile, only there is a rotatable plug to lack on socket panel of the invention
Mouthful, user will not be erroneously inserted, and operate simpler；And the plug breach is rotated with plug, plug is directly extracted power-off；
Also, after plug insertion socket conduction of the invention, plug cannot be rotated, and effectively overcome existing rotary electric connected mode
Easily rotation retracts and causes the unstable deficiency of contact.
