Patent ID: 7811069

Claim:
A fan, adapted for service as an equipment fan, comprising: a housing part ( 22 ) forming an external contour of an air passage opening ( 41 ) formed in the fan ( 20 ); a motor ( 21 ) for rotatably driving fan blades ( 40 ), that are mounted in the air passage opening ( 41 ), about a rotation axis ( 23 ); a carrier element ( 51 ) provided between the motor ( 21 ) and the housing part ( 22 ), the carrier element being oriented transversely to the air passage opening ( 41 ) and is configured as a trough ( 53 ) that serves to receive an electrical lead ( 52 ) and guides said electrical lead along a predetermined path or channel from the motor ( 21 ) to a predetermined location ( 64 ) adjacent an exterior of the housing part ( 22 ); and a deflection device ( 50 ) that is formed integrally with the housing part ( 22 ), and is, at least partially, adjacent said predetermined location ( 64 ) of the housing part ( 22 ) and which deflects the electrical lead ( 52 ) at a first deflection location ( 55 ) such that two electrical lead portions of said electrical lead, each contiguous to said first deflection location ( 55 ), together define a first plane generally perpendicular to said motor rotation axis ( 23 ); wherein the electrical lead is further deflected at a second deflection location ( 84 ) into a second plane which is oriented at a predetermined angle with respect to said first plane, said deflection device ( 50 ) thereby tending to prevent transmission of any longitudinal strain (F 1 ), exerted on a motor-remote portion of said electrical lead, to a motor-adjacent portion of said electrical lead, located between said first deflection location ( 55 ) and terminals of said motor ( 21 ); and wherein the first deflection location ( 55 ) is configured to deflect a successive linear motor-remote portion of the electrical lead ( 52 ) in a direction, angled in a range exceeding 120 degrees, with respect to a prior, motor-adjacent, linear portion of said lead.
