| 摘要 |
<p>The present invention relates to an electrical signal coupling device and more particularly to a rotary signal coupler suitable for use in transmitting electrical signals between transducers mounted on a shaft and wiring which is fixed relative to the structure in which the shaft is rotatably mounted. The invention provides a coupling device (10) comprising a first part (11) mountable on a rotary shaft (13) and a second part (16) mountable on said shaft (13) in juxtaposition to the first part (11). Said parts (11, 16) include respective conductors for electrically coupling said parts (11, 16). The coupling device (10) also comprises means (18) for maintaining a predetermined and substantially constant annular gap between the parts (11, 16) and means (21, 22) provided on the second part (16) for preventing rotation of said part (16) as the first part (11) rotates with said shaft (13).</p> |
