Abstract
The utility model provides a power adapter which comprises a shell, a PCB, at least two inserting pins, at least two guiding pins and a guiding pin supporting part, wherein the PCB is arranged in the shell, the inserting pins are connected with one end of the PCB, the guiding pins are connected with the other end of the PCB, and the guiding pin supporting part is used for arranging the guiding pins. Safety pipes are arranged among the inserting pins, so that the power adapter can not be burnt out, can not cause a fire, and is safe and practical in use; and the inserting pins are extended out of the shell and is parallel to the shell, so that the power adapter has small volume and convenient packing and transportation as well as smooth and attractive appearance.
Description
Technical field
The utility model relates to a kind of power supply adaptor.
Background technology
Power supply adaptor is the power supply conversion equipment of small portable electronic device and electronic apparatus, generally comprise housing, and be arranged on the interior pcb board of housing, and at least two pins that are connected with pcb board one end, and at least two lead foots that are connected with the pcb board other end.Present power supply adaptor adopts the direct injection mo(u)lding of pin is connected on the adapter housing mostly, pcb board is installed in the housing again, copper sheet on the pcb board is contacted with pin, yet this kind installation method efficient is lower, the easy and pin loose contact of copper sheet; And when pin and adapter injection mo(u)lding, pin also makes the adapter contour structure size bigger, heavy perpendicular to the setting of adapter housing, and is very inconvenient in packing and transportation.In addition,, when abnormal voltage occurring, burn out power supply adaptor easily on pcb board, can cause fire when more serious, cause very big potential safety hazard because protective tube is not set.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of easy for installation, power supply adaptor that volume is small and exquisite and safe and practical.The utility model is achieved through the following technical solutions:
A kind of power supply adaptor of the present utility model comprises housing, and is arranged on the pcb board in the housing, and at least two pins that are connected with pcb board one end, and at least two lead foots that are connected with the pcb board other end,
And be used to install the lead foot strutting piece of lead foot, and described pcb board is provided with the plug connector of pegging graft for pin, and described lead foot is connected with pcb board by the five metals shell fragment.
As preferably, be provided with protective tube between the described pin.
As preferably, described five metals shell fragment one end is connected with lead foot, and the other end passes pcb board and welds with pcb board.
As preferably, described lead foot strutting piece is stretched out by housing and forms, and is provided with the spliced eye of pegging graft for lead in the lead foot strutting piece.
As preferably, described pin extends to outside the housing, and is parallel to each other with housing.
As preferably, described plug connector is " ∏ " type.
As preferably, described housing is formed by face-piece and drain pan butt joint.
As preferably, described pcb board is provided with input circuit, protective tube F1, resistance R 1, R2, capacitor C 1, C2, diode bridge rectifier circuit BD1, diode ZD1, ZD2, ZD3 and output circuit.
Power supply adaptor of the present utility model because described pcb board is provided with the plug connector of pegging graft for pin, can be installed in pcb board in the housing earlier, pin is inserted in the plug connector again, installs very convenient; Described lead foot is connected with pcb board by the five metals shell fragment, and the five metals shell fragment passes pcb board and welds with pcb board, is connected firmly; Be provided with protective tube between the described pin, the situation of power supply adaptor can not occur burning out, more can not cause fire, safe and practical during use.Described pin extends to outside the housing, and is parallel to each other with housing, and volume is small and exquisite, and packed and transported is convenient, and the external form smoothness is attractive in appearance.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the three-dimensional combination figure of the utility model power supply adaptor;
