Compound adapter plug

The invention provides a composite adapter plug, in particular to a composite adapter plug which is convenient to carry and easy to operate.

More and more portable electronic products, such as laptops, tablets, mobile phones, digital cameras, camcorders, portable DVD, PDA, MP3, MP4, GPS, warm equipment, health care equipment. The electronic product has a plurality of ports that conform to different protocols and are incompatible with each other, and therefore need to carry multiple data lines to adapt to different ports, thereby causing troubles and inconvenience to consumers. In order to solve the above problems, a composite adapter plug having a plurality of plug connectors has emerged.

Chinese Patent No. CN200959458 discloses a simple multi-tasking type simple conversion plug and an adapter thereof, including an insulating housing, first and second plug assemblies, and a plug having two side arms And a first pivoting portion, the first and second plugging components are respectively coupled to the insulating housing, and are electrically connected to each other, the plug is movably coupled to the insulating housing, and is provided with the second plug The third component of the connector is docked with each other, and the side edge of the plug may be formed with a sliding groove to correspond to the first pivoting portion. Thereby, the insulating housing forms a joint with the first and second plug assemblies, and the plug can be slidably moved when not in use, and can be rotated to different directions, and the adapter can provide a repeating group It is then connected to a multi-tasking conversion plug to correspond to sockets of different specifications. However, the conversion plug is opposite to the second plug component and the second plug component When connected, there is no corresponding positioning structure between the first pivoting portion and the sliding groove, and the external force can easily pull the plug to affect the electrical connection between the third plug component and the second plug component.

In view of this, it is necessary to provide a new portable adapter plug that is easy to carry and easy to operate to overcome the above drawbacks.

It is an object of the present invention to provide a composite adapter plug that is easy to carry and easy to operate.

To achieve the above object, the present invention adopts the following technical solution: a composite adapter plug includes a first plug and a second plug pivotally connected to the first plug. The first plug includes a first insulative housing, and a first connector and a second connector respectively coupled to the first insulative housing and electrically connected to each other. The second plug includes a second insulative housing, a third connector coupled to the second insulative housing and movable relative to the second insulative housing, and slid relative to the second insulative housing to drive the third connector Button. The third connector is operatively docked with the second connector.

Compared with the prior art, the composite adapter plug of the present invention slides relative to the second insulating housing to drive the third connector to move, so that the first connector is after the third connector is docked with the second connector. The use state and the third connector are separated from the second connector and rotated, and are in an independent use state, so that one data line can have different connectors to adapt to different ports of the electronic product, which is convenient to carry and easy to operate.
