Attachment structure for attaching fan unit to main body of electrical equipment, connector connecting main body of electrical equipment and fan unit, and electrical equipment

Abstract

An attachment structure enabling more efficient work in performing maintenance of a fan of a fan unit and a more stable electrical connection between a main body of an electrical equipment and a fan unit. An attachment structure configured to detachably attach a fan unit including a fan and a casing housing the fan to/from a main body of an electrical equipment includes a guide mechanism configured to guide a slide motion of sliding the casing in one direction relative to the main body to dispose the casing at a mounting position, and a retaining mechanism configured to restrict movement of the casing relative to the main body in a direction opposite the one direction when the casing is disposed at the mounting position by the slide motion.

1 . A connector provided at one of a main body of an electrical equipment and a fan unit detachably attached to the main body, and configured to be connected to a counterpart connector provided at the other of the main body and the fan unit, the connector comprising:
 a fixed portion fixed to the one of the main body and the fan unit; and   a movable terminal portion supported by the fixed portion so as to be displaceable in a direction intersecting a connection direction of the connector to the counterpart connector, and configured to be connected to the counterpart connector.   
     
     
         2 . The connector of  claim 1 , wherein the movable terminal portion is supported by the fixed portion so as to be further displaceable along the connection direction. 
     
     
         3 . The connector of  claim 1 , wherein the fan unit includes:
 a fan; and   a casing configured to house the fan,   wherein the fixed portion is formed integrally with the casing.   
     
     
         4 . The connector of  claim 1 , wherein the fan unit includes:
 a fan;   a casing configured to house the fan; and   a substrate fixed to the casing,   wherein the fixed portion is fixed to the substrate.   
     
     
         5 . An electrical equipment comprising:
 a main body;   a fan unit detachably attached to the main body; and   the connector of  claim 1 .   
     
     
         6 . The electrical equipment of  claim 5 , wherein the electrical equipment is a numerical control device configured to control a machine tool, or a motor drive device configured to supply power to a servomotor provided in a machine tool.
