Replaceable plug size power adapter plug

The present invention relates to a power adapter plug, and more particularly to a power adapter plug of a replaceable plug size.

Due to the booming development of the electronics industry, the market continues to introduce electronic products with various functions. Among the existing electronic products, portable electronic products are particularly popular among users, such as MP3 players, mobile phones, and tablets. Computers, etc., are the electronic products that today’s office workers will carry with them when they are on a business trip or when they are traveling by the general public. Although the above-mentioned various electronic products are supplied with rechargeable batteries, the power supplied by the batteries is usually not sustainable. For a few days, most users will carry a set of power adapter plugs to connect the electronic products to the mains power supply for charging; however, the existing plugs and mains sockets are roughly divided into 14 specifications, which are A to N type (type A~type N), and different countries will adopt different types of plugs and sockets due to their domestic power technology maturity. For example, the United States adopts A type and B type. In European countries, such as France, E Type, Germany adopts F-type, because the pins of the above various specifications plugs and the jacks of various specifications of the mains socket are not necessarily universal, therefore, various electric When users of products travel or travel between countries, they must carry multiple sets of power adapter plugs that match the national electrical outlets to suit the mains outlets of each country. In this way, in addition to the space occupied by the luggage, multiple power adapters The weight of the plug The amount will also cause a big burden on travel or business trips.

In view of the fact that the plugs of the existing power adapters cannot be commonly used in various types of commercial power sockets, and the user has to carry a plurality of power adapter plugs, the present invention proposes a power adapter plug of a replaceable plug specification.

The main technical means for achieving the above purpose is that the power adaptor plug of the replaceable plug specification comprises: a device box, the outer wall surface is formed with a slot seat, the slot seat has two abutting plate inlets, and the slot seat The inner wall surface is formed with two fixing grooves on the opposite sides of the corresponding two-way plate inlet, and two groove rails respectively connecting the two-plate inlet and the corresponding fixing groove are formed; a power conversion component is disposed at the The device box includes a power circuit, two terminals and a connecting line. The two terminals are electrically connected to the power circuit, and respectively protrude from the two fixing slots of the device box slot, and the connecting wires are electrically connected to the power source. And a plug member is detachably disposed on the housing of the device box, and includes a base and two pins disposed on the base, each of the pins forming a resisting plate, and The two pins of the two pins are respectively aligned with the two plate receiving inlets of the device box slot and respectively slid into the corresponding groove rails, and then the plug member is rotated relative to the device box, so that the resisting plate is slid along the groove rail to the corresponding Fixed slot and respectively resisted Should terminals.

In the above power adapter plug, the plug component can be removed and replaced from the device box, so that the user can replace the plug component of the corresponding specification for the jack specification of the commercial power socket of each country, and the utility model can be used for different specifications of the utility power socket. The replacement of the plug parts is suitable for different commercial power socket specifications in different countries, and reduces the inconvenience and burden caused by carrying multiple power adapter plugs; when installing the plug component, it is only necessary to make the board of the plug component pins separate from the board. The inlet is slid into the corresponding groove rail, and the plug member is rotated relative to the device box to fix the plug member to the device box, and is electrically connected to the power circuit through the two terminals, and is easy to assemble and disassemble.
