## Abstract

A transfer plug for a variety of sockets includes an insulating shell, a first and a second connectors and a signal plug. The insulating shell has two side arms and a first pivoted portion. The first and the second connectors correspondingly combine with the insulating shell respectively and are electrically connected. The signal plug movably connects to the insulating shell and has a third connector connecting to the second connector. The signal plug has a gliding groove in a lateral edge thereof. The insulating shell combines with the first and second connector to form a transiting plug. The signal plug can slidably move and turn in different directions in an unused state. The signal plug can be used alone and doesn't need to be disassembled. The transiting plug can be repeatedly connected to other transiting plugs and converted into a multitasking transfer plug with different specifications and types of sockets.

## Claims

### Claim 1

A transfer plug, comprising:
an insulating shell, said insulating shell having a first body portion and a second body portion, said second body portion separably connectable to said first body portion;
a first connector formed on a first end of said shell, said first connector being formed on said first body portion;
a second connector formed on a second end of said shell and electrically connected to said first connector; and
a pair of arms connected to said second end of said shell and comprising a receiving groove formed on an inner lateral surface of said pair of arms, said second connector and said pair of arms being formed on said second body portion.

### Claim 2 (depends on 1)

The transfer plug of claim 1, further comprising a signal plug comprising a third connector which is connectable to the second connector, and including a pair of protruding portions formed on a side of said signal plug and inserted into said receiving groove formed on said inner lateral surface of said pair of arms.

### Claim 3 (depends on 1)

The transfer plug of claim 1, further comprising:
a transmission line for electrically connecting said first and second body portions.
