Abstract
The utility model relates to a plug and especially relates to a foldable and portable three-phase plug. The plug comprises a main shaft, a mainboard, side plates and a conducting plate. One end of the mainboard is fixed on the main shaft. The two side plates are arranged on two sides of the mainboard and one end of each side plate is hinged with the main shaft. The main shaft and each side plate are provided with one groove respectively. The mainboard is provided with a square through hole which is matched with a reverse protrusion portion of a groove on each side plate. One end of the conducting plate is inserted into the groove and is hinged with the main shaft or the side plates. A conducting plate winding hinge end can be folded and placed in the groove. The plug of the utility model has the advantages that a plug structure is improved; compared to the prior art, by using the plug of the utility model, the size of the plug is further is reduced; simultaneously, security and firmness are increased; the design of the whole device is reasonable, small and easy to use; the plug is especially suitable for being used as the plug of portable and mobile equipment.
Description
Technical field
The utility model relates to a kind of plug, is specifically related to a kind of Collapsible mobile 3-phase plug.
Background technology
Along with the development of information technology, laptop computer and panel computer are more universal, and its thickness is also more and more thinner, yet the plug matching is with it still larger.At present, 3-phase plug is roughly 4cm * 4cm * 5cm size, often takies a lot of unnecessary spaces, can seem especially lofty while especially putting into bag.
For this problem, two kinds of existing main methods that reduce 3-phase plug volume, one: utilize groove that three sheet metals are folded into, yet still can not reduce the width of plug like this, cumulative volume is still larger; Its two: the foldable plug that Britain is up-to-date, the metal insert on both sides used time not rotate to the same straight line of sheet metal that ground wire connects on, then both wings are rotated, plug volume just greatly reduces like this, yet this technology still has weak point, as three sheet metals still expose, aspect width, occupy at least space of 2cm.In prior art, exist the technical scheme of both combinations, yet aspect space-saving and safety guarantee, have obviously deficiency, turning device is more easy to wear after folding, dislocation.
Utility model content
Goal of the invention: the purpose of this utility model is to provide that a kind of volume is simplified, safety Collapsible mobile 3-phase plug firmly.
Technical scheme: for achieving the above object, three plugs of a kind of Collapsible mobile of the utility model, comprise main shaft, mainboard, side plate and conducting strip, and mainboard one end is fixed on main shaft, two side plate apportion mainboard both sides and every block of side plate have one end and main shaft hinged; Described main shaft and every block of side plate are provided with a groove, described mainboard is provided with the square through hole suitable with the reverse ledge of side plate upper groove, described conducting strip one end is stretched into groove and is hinged with main shaft or side plate, and conducting strip can be rolled over and put in groove around hinged end; Described side plate is being provided with symmetrical connecting groove with main shaft hinged end, connecting groove inwall is provided with elastic sheet metal, in described main shaft, be connected with live wire and zero line, live wire and zero line extend main shaft portion and are fixed with wiring column cap, described wiring column cap is corresponding one by one with connecting groove, and wiring column cap is hinged with side plate by elastic sheet metal extruding.
In order to make device safer, on described live wire circuit, add fuse.
Beneficial effect: the utility model has the advantages that and improved plug construction, compared with prior art further reduced the volume of plug, increased fail safe and firmness, whole device is reasonable in design, small and exquisite easy-to-use simultaneously, is particularly suitable for doing the plug of portable mobile equipment.

Embodiment
As shown in Figure 1 and Figure 2, three plugs of a kind of Collapsible mobile of the utility model, comprise main shaft 1, mainboard 2, side plate 3 and conducting strip 4, and mainboard 2 one end are fixed on main shaft 1, two side plate 3 apportion mainboard 2 both sides and every block of side plate 3 have one end and main shaft 1 hinged; Described main shaft 1 is provided with a groove 5 with every block of side plate 3, described mainboard 2 is provided with the square through hole 6 suitable with the reverse ledge of side plate 3 upper grooves 5, described conducting strip 4 one end are stretched into groove 5 and are hinged with main shaft 1 or side plate 3, and conducting strip 4 can be rolled over and put in groove 5 around hinged end; Described side plate 3 is being provided with symmetrical connecting groove 7 with main shaft 1 hinged end, connecting groove 7 inwalls are provided with elastic sheet metal 8, in described main shaft 1, be connected with live wire 9 and zero line 10, live wire 9 and zero line 10 extend main shaft portion and are fixed with wiring column cap 11, described wiring column cap 11 is corresponding one by one with connecting groove 7, and wiring column cap 11 is hinged with side plate 3 by elastic sheet metal 8 extruding.
As shown in Figure 4, plug side plate 3 when not using is folded closed state, as shown in Figure 1 side plate 3 is outwarded winding in use, live wire 9 on main shaft 1 combines with connecting groove 7 by wiring column cap 11 with zero line 10 with turning circuit fixed main shaft 1 and side plate 3, in addition by conducting strip 4 from the interior back-out of groove 5, plug normally can be used afterwards.If electric current is excessive in circuit, fuse 12 will burn with protective device as shown in Figure 6.When plug is obsolete, conducting strip 4 and side plate 3 is successively closed, and the reverse protuberance of side plate 3 upper grooves 5 is nested in square through hole 6, and whole plug is closure state, is convenient to deposit and carry.
