Abstract

A lead wire engaging structure (21)includes a first engaging portion (23)and a second engaging portion (25). One end of the first engaging portion (23)and one end of the second engaging portion (25) are integrally provided at a first mounting portion (14A)integrally provided at a second casing wall portion (11). The first engaging portion (23) forms a first gap (27) between the first engaging portion (23)and the second casing wall portion (11), and engages four lead wires (7)in cooperation with the second casing wall portion (11). The first gap (27) allows the four lead wires (7)to pass therethrough. The second engaging portion (25) forms a second gap (29)between the second engaging portion (25) and the first engaging portion (23). The second gap (29)allows the four lead wires (7) to pass therethrough. The other end portion of the first engaging portion (23)and the other end portion of the second engaging portion (25)are coupled to each other by a coupling portion (31).

Description

technical field [0001] The present invention relates to a lead wire locking structure for locking a lead wire on an electrical equipment case and an electrical equipment. Background technique [0002] In the centrifugal fan (electrical equipment) shown in Japanese Patent Application Laid-Open No. 11-230083 (Patent Document 1), a groove is formed on the outer wall of the wall facing the suction port of the casing, and multiple fans are accommodated in the groove. A lead wire is provided, and a claw-shaped protrusion extends along the opening of the groove, and the claw prevents the lead wire from protruding from the groove. [0003] In addition, in Japanese Patent Laid-Open No. 2005-303015 (Patent Document 2), it is shown that the lead wires are accommodated in the grooves provided on the web of the axial flow fan, and the lead wires protruding from the grooves are locked to the wires provided on the casing. The lead locking structure on the outer wall of the [0004] In ad...
