The rotatable coupling is particularly suitable for use with electric guitars, where there is a perceived problem with the twisting of the cable which connects the guitar and the amplifier. The rotatable coupling thereby provides an alternative to a traditional Mercury slip-ring which avoids the handling precautions involved with Mercury while also preventing cable twisting. The rotatable coupling comprises a stator (302, figure 4) and a rotor (303, figure 4) defining an electrical rotary interface 301 for providing continuous connection between audio cables 104, 105. A protective stator housing 304 retains the stator and a protective rotor housing 305 retains the rotor. A rolling-element bearing (306, figure 4) is positioned between the protective stator housing and the protective rotor housing, such that the inner race of the bearing is journaled with the rotor housing and the outer race is journaled with the stator housing. The bearing thereby removes stress from the rotor and stator contacts. |
