Embodiment Construction
[0018] The power supply device of the present invention will be further described below in conjunction with the description of the drawings and specific implementation methods.
[0019] Such as Figure 1 to Figure 4 shown. A power supply device 100 with a hidden power plug, which includes a housing 10 and a control circuit inside the housing 10 (not shown in the figure, the control circuit adopts conventional power rectification and related control circuits). The casing 10 is provided with a power plug 12 electrically connected to the control circuit and an output port 11 , and a receiving chamber 13 is provided on the casing 10 , and the power plug 12 can be completely accommodated in the receiving chamber 13 . There are many types of the output port 11, which may be a USB interface or a circular interface. The control circuit includes a power supply circuit for regulating the input voltage and an output circuit for outputting the voltage. The power plug 12 disposed on the...

The invention provides a power supply device with a suppressible power resource plug, which comprises a casing and a controlling circuit arranged inside the casing. A power resource plug and an output port electrically connected with the controlling circuit are arranged on the casing; an accommodating chamber is further arranged on the casing; and the power resource plug can be totally accommodated in the accommodating chamber. The invention solves the technical problem that the power resource plug of the power supply device in the prior art is revealed and the contact chip is exposed to the outside environment, so that the plug is easily to get rust and inconvenient for storing and taking by providing a power supply device which is provided with an accommodating chamber, and can hide the power resource plug inside, so as to achieve safety and convenience use, avoid rusting, and facilitate storing and taking.
Description
technical field [0001] The invention relates to the technical field of power supply devices, in particular to a power supply device with a concealable power plug. Background technique [0002] At present, various digital portable electronic products are playing an increasingly important role in people's lives. The normal use of this type of product is all inseparable from electricity, so there are many types of existing power supply devices. However, the power plugs of the existing power supply devices are all exposed, especially when the contacts are exposed to the environment when idle, the contacts are prone to rust and are inconvenient to store and carry. Contents of the invention [0003] In order to solve the technical problems that the power plug of the power supply device in the prior art is exposed, and the contacts are exposed to the environment when idle, the contacts are easy to rust, and it is inconvenient to store and carry. Among them, the power supply dev...
