Description
Technical field
The present invention relates to a kind of can folding plug, have can folding plug electronic installation and connect pedestal, refer to a kind ofly have many pins and the attaching plug that can launch or fold especially, the electronic installation with this kind of plug can the connection pedestal of folding plug in order to be connected to power supply and to accommodate this.
Background technology
When electric equipment products are in order to connect power supply, use plug very at large.But conventional known attaching plug mostly is fixed plug, the use that the unfavorable storage of this type of plug is carried.
Plug, as the indispensable instrument of connecting circuit product and power supply, faces the trend that various electric equipment products continue towards volume Miniaturization Design, and the plug occupying certain volume will face the problem of how reduced volume eventually.
With the common attaching plug with three pins for example, it comprises two conductive base pins and an earth pin.Three pin distributions triangular in shape of this kind of plug, when storage enters electronic installation inside, by taking the inner larger volume of electronic installation, not only increasing the volume of electronic installation, also reducing the convenience of portability and movement.
The known patent reducing the plug of storage volume, such as, have DE to be DE20014987U1; UK Patent Application publication number is GB2381669A, GB2417141A, GB2436465A, GB2436899A; PCT patent application publication number is the patent applications such as WO0147071A1, WO2009152631A1, WO2010089356A1, WO2006046541A1, and United States Patent (USP) grant number is the patent of US1485193.
Such as, but when the container structure of designing power supply plug, also need to meet the needs that security for all countries specifies, regulation is wherein the state that the conductive base pin of plug and earth pin need keeping parallelism simultaneously.Above-mentioned UK Patent Application publication number of illustrating is the patent application of GB2436899A, also being disclosed as Chinese application publication number is CN101461104A, denomination of invention is the patent application of " plug with rotatable pin ", although three pins can be rotated and become smaller size smaller to receive, but its three pins are not state parallel to each other in storage process, therefore just do not meet some specific security regulations.Therefore how to meet specific security regulations, reducing volume that plug takies to reduce overall accommodation space, is the problem that the structural design of plug will solve.
Summary of the invention
Technical problem to be solved by this invention, for the deficiencies in the prior art, there is provided a kind of can folding plug, have can folding plug electronic installation and connect pedestal, the shortcoming that the unfavorable storage of known fixed plug is carried can be solved, and under the prerequisite maintaining conductive base pin parallel with earth pin (that is these described pins are parallel along its axis direction), reduce the space that plug folds, be beneficial to storage and carry.
In order to solve the problems of the technologies described above, the invention provides one can folding plug, and it comprises an insulator foot, a pair first pins and one second pin.This insulator foot has the second position that one first position and is sticked in this first position, and linear displacement relatively can be made in this first position and this second position.This at least one first pin is arranged on this first position.This second pin is arranged on this second position, when wherein this first position and this second position are relatively moved, this second pin first pin at least one relative to this keeps the state along its axis parallel, and this at least one first pin and this second pin selectively present deployed condition away from each other or be collapse state close to each other thus.
In addition, the present invention also provides that a kind of have can the electronic installation of folding plug, reduces the inner space taking electronic installation, plug can be launched during use during plug storage.
This electronic installation comprises one can folding plug and a connecting seat body.This can comprise an insulator foot, a pair first pins and one second pin by folding plug.This insulator foot has the second position that one first position and is sticked in this first position, and linear displacement relatively can be made in this first position and this second position; This at least one first pin is arranged on this first position; This second pin is arranged on this second position, when wherein this first position and this second position are relatively moved, this second pin first pin at least one relative to this is held in parallel state, and this at least one first pin and this second pin selectively present deployed condition away from each other or be collapse state close to each other thus.This Connection Block body forms an accommodation space, and wherein this insulator foot is located in this accommodation space movably.
The present invention also provides a kind of and connects pedestal, what collecting one had the first position and the second position can folding plug, wherein linear displacement relatively can be made in this first position and this second position, this connection pedestal comprises: an accommodation space, its profile corresponds to this can this first position of folding plug, and this first position is movably located in this accommodation space; And a wider space, be communicated in this accommodation space, its profile corresponds to this can this second position of folding plug, and this second position is movably located in this accommodation space.
The present invention has following beneficial effect: the present invention can maintain under the conductive base pin prerequisite parallel with earth pin, and this selectively presents deployed condition away from each other to the first pin and this second pin or is collapse state close to each other.When this first position and this second position are relatively moved, this second pin is held in parallel state relative to this to the first pin, is arranged in a straight line to make these described pins fold, to reduce the volume taken; In addition, retracting structure of the present invention is very succinct, can reduce manufacturing cost.
