Patent ID: 7986071

Claim:
A slot closure arrangement, comprising: a sliding block which extends in a direction of a longitudinal axis; a pressure piece which extends in the direction of the longitudinal axis; at least one spring element which extends in the direction of the longitudinal axis, wherein the spring element with the pressure piece forms a bending-beam arrangement in a direction of a lateral axis which extends transversely with respect to the longitudinal axis, such that the spring element can be bent by the pressure piece in a direction of a vertical axis which is arranged transversely with respect to the longitudinal axis and with respect to the lateral axis; and an attachment means for prestressing the spring element before insertion of the slot closure arrangement into a slot in an electrical machine, wherein the at least one spring element includes multiple electrically insulating fibers which are aligned unidirectionally in the direction of the lateral axis and are connected to one another by a resin, and the attachment means is configured for mechanical movement from a first position to a second position, which can be monitored after positioning of the slot closure arrangement in the slot, such that prestressing of the spring element can be released.
