Patent number: 9812819Abstract: A power cord includes a plug and a load connection portion connected to a load. The plug contains a plurality of plug pins which are respectively inserted in plug pin insertion holes of a power socket and connected to the power socket and a plurality of PTC thermistors, at least one of which is provided for each of the plug pins to detect a temperature of the corresponding plug pin. The PTC thermistors form one series circuit, and the power cord includes a shut-off device which turns off power supply to the load connection portion from the plug pins when a resistance value of the series circuit is equal to or higher than a predetermined value.Type: GrantFiled: December 15, 2014Date of Patent: November 7, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Takashi Kawamoto, Maki Kondou, Ryota Tomiyama, Koji Yamato

Patent number: 9589745Abstract: A power cord includes a plug having blades and a thermal sensor configured to detect a temperature, and a cut-off means configured to stop electric power from being supplied to the load connection portion from the blades when a temperature detected with the thermal sensor is higher than a prescribed temperature. The plug includes a core which retains the blades and the thermal sensor, and an enclosure which is formed by molding synthetic resin to cover an outside of the core. A part of the thermal sensor protrudes from the core to be buried in the enclosure.Type: GrantFiled: August 2, 2013Date of Patent: March 7, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Maki Kondou, Takashi Kawamoto, Ryota Tomiyama

Publication number: 20120184132Abstract: A plug is adapted to be connected to a DC outlet to supply a DC power to the plug. The plug includes plug pins and a substantially quadrangular-shaped surrounding wall for surrounding the plug pins. The DC outlet includes: an outlet main body having an outlet unit to which the plug is adapted to be connected. The outlet unit includes a plug-receiving portion having pin-inserting holes into which the plug pins are inserted; an insertion groove formed to surround a periphery of the plug-receiving portion, the insertion groove being adapted to receive the surrounding wall; and pin-receiving pieces for being connected with the plug pins that are respectively inserted through the pin-receiving holes. Two pin-receiving holes corresponding to the pin-receiving pieces are arranged along a reference side of the plug- receiving portion and offset closer to the reference side than an opposite side to the reference side.Type: ApplicationFiled: August 2, 2010Publication date: July 19, 2012Applicant: Panasonic Electric Works Co., Ltd.Inventors: Kazuhiro Katou, Maki Kondou, Takashi Kawamoto, Toshiyuki Takii, Satoru Ueno
