Abstract
The utility model provides a power adapter. The power adapter comprises an upper cover, a lower cover, a plug and a circuit board. The upper cover and the lower cover are fastened and form a shell. The circuit board is located in the shell. A through hole through which the plug passes is arranged on the upper cover. The plug comprises a vertical segment and a horizontal segment. The vertical segment and the horizontal segment are connected and form an L-shaped structure. The horizontal segment is contacted with the circuit board so as to provide power for the circuit board. The vertical segment passes through the through hole. The plug of the utility model does not need injection molding and a welding connecting line. Therefore, the structure of the utility model can be simplified; production is simple and manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of power supply adaptor, relates in particular to a kind of power supply adaptor with bending plug.
Background technology
Power supply adaptor is a kind of power inverter commonly used, and its plug be used for to insert socket and obtains electric power, and electric power is delivered to wherein circuit board.The manufacturing process of plug is more at present, for example, is contained in injection moulding in the mould, at plug weldering connecting line; Be contained in injection moulding in the mould, shoot sheet and make rotary connector; Assembled plug, the weldering connecting line.As seen, present plug all needs injection moulding or weldering connecting line during fabrication, causes complex manufacturing, and manufacturing cost increases.
Summary of the invention
The purpose of this utility model is to provide a kind of power supply adaptor, to solve the complex manufacturing that the existing power supply adaper plug exists, the problem that manufacturing cost increases.
In order to address the above problem, the utility model provides a kind of power supply adaptor, it comprises loam cake, lower cover, plug and circuit board, described loam cake and described lower cover fasten and form a housing, described circuit board is arranged in described housing, cover the through hole that is provided be used to passing described plug on described, described plug comprises vertical section and horizontal segment, described vertical section and described horizontal segment connect into L shaped structure, described horizontal segment and described circuit board butt are to power to described circuit board, and described vertical section is passed described through hole.
According to a kind of preferred implementation of above-mentioned power supply adaptor, wherein, also comprise screw, described screw passes described loam cake and described circuit board to increase the bonding strength between described horizontal segment and the described circuit board.
According to a kind of preferred implementation of above-mentioned power supply adaptor, wherein, the inboard of described loam cake is provided with three projections, and the inboard of described lower cover is provided with three joint pins, and the end face of described joint pin is provided with deep hole, and described projection is inserted respectively in the described deep hole.
The utility model plug does not need together injection moulding, does not need to be welded to connect line, and whereby, the structure of plug portion of the present utility model can be simplified, and production technology is simpler, and manufacturing cost is lower.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 and Fig. 2 show the surface structure of the utility model preferred embodiment, and Fig. 3 shows the syndeton of plug, circuit board and the screw of the utility model preferred embodiment inside, and Fig. 4-Fig. 7 shows the internal mechanical structure of the utility model preferred embodiment.As shown in the figure, this preferred embodiment comprises plug 1, loam cake 2, lower cover 3, circuit board 10 and screw 4.Loam cake 2 and lower cover 3 fasten and form a housing, circuit board 10 is arranged in housing, loam cake 2 is provided be used to the through hole 22 that passes plug 1, plug 1 comprises vertical section 12 and horizontal segment 11, vertically section 12 and horizontal segment 11 connect into L shaped bending structure, horizontal segment 11 and circuit board 10 butts are to power to circuit board 10, and vertically section 12 is passed through hole 22.
In addition, this preferred embodiment also comprises screw 4, and screw 4 passes loam cake 2 and circuit board 10, loam cake 2 is pressed horizontal segment 11 tightly and is put on circuit board 10, to increase the bonding strength between horizontal segment 11 and the circuit board 10, also, make close contact between the Copper Foil on horizontal segment 11 and the circuit board 10.
In this preferred embodiment, loam cake 2 is connected with lower cover by projection 21, joint pin 31 connections, and loam cake 2 and lower cover 3 fasten, joint pin 31 is provided with deep hole,,, loam cake 2 can be fixedly connected with lower cover 3 in the deep holes that projection 21 is inserted on the joint pins 31 with after screw 21 aligns at joint pin 31.Wherein, joint pin 31 and projection 21 are three, and be corresponding one by one, is isosceles triangle and arranges.
To sum up, the utility model by improve plug and and circuit board between syndeton, when producing, plug need not be put together injection moulding in the mould into, improves machine efficiency, mounting circuit boards can be saved soldered wires on the bending plug.Like this, the bending plug not only has fixation, can not be pulled out, and the horizontal segment of bending can also be used to contact electric action with the circuit board Copper Foil.Whereby, structure of the present utility model is simplified, and production technology is simpler, and manufacturing cost is lower.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its Spirit Essence or essential feature.Therefore, described disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
