FIBER RETAINER, ELECTRICALLY CONDUCTIVE RING FOR BEARING ELECTRICAL CORROSION PROTECTION, AND ELECTRIC MOTOR

Disclosed in the present invention is a fiber retainer, comprising a body. The body internally has a fiber accommodating hole provided along the length thereof, and the fiber accommodating hole is used for accommodating an electrically conductive fiber. The body comprises an anti-separation portion and a fixing portion, wherein the fixing portion and the anti-separation portion constitute the body, and the anti-separation portion has an outer diameter greater than that of the fixing portion. The fiber accommodating hole is formed at least inside the fixing portion and extends to an end of the body; and the fixing portion deforms after being subjected to an external force, so that an inner diameter of part of the fiber accommodating hole is reduced, thereby fixing the electrically conductive fiber in the body. In the present invention, the fiber retainer fixes an electrically conductive fiber by means of the fixing portion thereof, and provides an axial binding force.
