A rotational split adaptor for engaging with gold-plated contacts of a communication
socket is introduced to comprise a common plug, a socket assembly and a rotational
joint. The common plug further includes a plug end for engaging with the communication
socket and an opposing first oblique surface. The socket assembly further includes
a splitter and an opposing second oblique surface. The splitter has a plurality
of parallel sockets electrically coupling with the communication socket, and the
second oblique surface is used to pair with the first oblique surface. The rotational
joint is constructed to pair the first oblique surface and the second oblique surface
so as to provide angular sliding in between and thus to alter angling between the
socket assemble and the common plug.
