Patent number: 6579103Abstract: In a conventional roller connector, when a spoke member of a steering device hits against an electrical lead-through section of a movable housing, there occurs a knocking sound, which will be unpleasant to the driver. The present invention, therefore, provides a roller connector which will not produce the knocking sound. Flexible cables are connected at least at one end to the electrical lead-through section of a movable housing. An elastic member is projectingly disposed on a surface of the upper wall where the electrical lead-through section protrudes, thus being driven to turn the movable housing.Type: GrantFiled: May 9, 2001Date of Patent: June 17, 2003Assignee: Alps Electric Co., Ltd.Inventor: Shunji Araki

Patent number: 6435885Abstract: A flexible cable is constructed in a band-like shape by sandwiching a plurality of conductive wires with a pair of insulating films, and a lead block is constructed by fixing a plurality of joint bars to a resin body. In a connecting structure of the flexible cable and the lead block, a part of one of the insulating films is removed so that the conductive wires are exposed at an end of the flexible cable. In addition, through holes for preventing deformation are formed in the remaining insulating film at positions between the exposed parts of the conductive wires. The exposed parts of the conductive wires are connected to the joint bars at positions close to the through holes by ultrasonic welding.Type: GrantFiled: June 21, 2001Date of Patent: August 20, 2002Assignee: Alps Electric Co., Ltd.Inventors: Shunji Araki, Ichiro Shirako
