Abstract
The utility model relates to a kind of power supply adaptors, including shell and the circuit board being placed in one, the shell is by cylindrical case and is fixedly connected on the upper plate of cylindrical case upper and lower end face and lower plate is constituted, upper plate and lower plate are Parallel Design, lower plate is equipped with alternating current and imports slotting, it is equipped with the alternating current for importing with the alternating current and inserting and only aligning on upper plate and exports jack, is equipped with direct current electricity output guide hole in the side wall of cylindrical case.The slotting exchange jack only to align of input is exchanged with bottom surface since the shell upper bottom surface in power supply adaptor is equipped with, make the overlappable use of multiple power supply adaptors, to save power outlet and desk-top space, and structure is simple, and the power supply adaptor suitable for various different circuit structures uses.
Description
Technical field
The utility model relates to a kind of power supply adaptor, especially a kind of are equipped in its shell upper bottom surface to exchange with bottom surface
The power supply adaptor for inserting the exchange jack only to align, makes the overlappable use of multiple power supply adaptors, inserts so as to save power supply
Seat.
Background technique
Power supply adaptor is the power supply conversion equipment of small portable electronic device and electronic apparatus, its work is former
Reason exchange input is converted to direct current output.It is matched in security protection camera, set-top box extensively, router, phone charger etc. are set
In standby.
General power supply adaptor is equipped with exchange input in the bottom surface of its shell and inserts only, is equipped in a side of shell
USB socket, or low-voltage DC is directly exported by conducting wire.On existing desk or in household electrical appliance, need increasingly
More power supply adaptors, such as set-top box, router, phone charger etc., since each power supply adaptor will occupy one group
The jack of socket, although there is multiple groups jack in socket, since power supply adaptor is only more much greater than commonly inserting, most of rows
Second power supply adapter cannot be reused after a power supply adaptor by plugging, when there is multiple power supply adaptors to make
Used time will use multiple sockets.
Summary of the invention
The purpose of this utility model is that the characteristics of according to existing power supply adapter, provide a kind of improved power adaptation
Device is specifically equipped in the shell upper bottom surface of power supply adaptor and exchanges the slotting exchange jack only to align of input with bottom surface, makes
Multiple overlappable uses of power supply adaptor, to save power outlet.
The utility model, including shell and the circuit board being placed in one, the shell is by cylindrical case and is fixedly connected
Upper plate and lower plate in cylindrical case upper and lower end face are constituted, and upper plate and lower plate are Parallel Design, and lower plate, which is equipped with, to be handed over
Galvanic electricity, which imports, inserts only, and the alternating current for importing with the alternating current and inserting and only aligning is equipped on upper plate and exports jack, in tubular
The side wall of shell is equipped with direct current electricity output guide hole.
The utility model is equipped with a pair of of slot in the inside of cylindrical case in its longitudinal direction, and circuit board is placed in slot
In.
The utility model, on the inner wall of cylindrical case, be equipped with column muscle, the upper and lower side of column muscle respectively with upper plate and bottom
Plate connects.Column muscle can not only increase the mechanical strength of cylindrical case, while also improve the secured of upper plate and lower plate
Degree.
USB socket can be arranged on the direct current electricity output guide hole in the utility model, and USB socket is electrically connected with circuit board
It connects, the low-voltage DC of circuit board can also be exported by conducting wire through direct current electricity output guide hole.
The utility model only aligns since the shell upper bottom surface in power supply adaptor is equipped with to exchange to input to insert with bottom surface
Exchange jack, make the overlappable use of multiple power supply adaptors, to save power outlet and desk-top space, and structure is simple,
Power supply adaptor suitable for various different circuit structures uses.
Detailed description of the invention
Fig. 1 is embodiment surface structure perspective view, and Fig. 2-Fig. 3 is structure principle chart, wherein Fig. 2 is the B-B section view of Fig. 3
Figure, Fig. 3 are the A-A cross-sectional view of Fig. 2.
In figure, 1, cylindrical case；2, upper plate；3, lower plate；4, alternating current, which imports, inserts only；5, alternating current exports jack；
6, direct current electricity output guide hole；7, circuit board；8, slot；9, column muscle.
Specific embodiment
- Fig. 3 referring to Fig.1, a kind of power supply adaptor, including shell and the circuit board 7 being placed in one, the shell is by tubular
Shell 1 and the upper plate 2 and the composition of lower plate 3 for being fixedly connected on 1 upper and lower end face of cylindrical case, upper plate 2 and lower plate 3 are
Parallel Design, lower plate 3 are equipped with alternating current importing slotting 4, are equipped on upper plate 2 and import slotting 4 relatively with the alternating current
Neat alternating current exports jack 5, and alternating current exports the alternating current of jack 5 and circuit board（220V）Electrical connection, alternating current export are inserted
The setting and connection of the electrical contact inserted sheet in hole 5 are same or similar with the jack of existing socket, are equipped in the side wall of cylindrical case 1 straight
Galvanic electricity exports guide hole 6, in the inside of cylindrical case 1, is equipped with a pair of of slot 8 in its longitudinal direction, circuit board 7 is placed in slot 8
In, on the inner wall of cylindrical case 1, it is equipped with column muscle 9, the upper and lower side of column muscle 9 is connected with upper plate 2 and lower plate 3 respectively.
USB socket, USB socket and circuit board electrical connection are set on the direct current electricity output guide hole 6, the low-voltage DC of circuit board is defeated
Outlet can also be exported by conducting wire through direct current electricity output guide hole 6.
The utility model, remaining structure（Such as the structure of circuit board）It is same or similar with existing power supply adapter.
