Publication number: 20230261417Abstract: An object of the present disclosure is to relieve tension applied to a cable. A cable connection device (2) includes a first holder (3), a second holder (4) and a support (5). The first holder (3) is configured to hold a tip part (111) of an end (110) of a first cable (11). The second holder (4) is configured to hold an intermediate part (112) of the end (110). The support (5) is configured to support the first holder (3). The second holder (4) is fixed with respect to a power feed control device body (10). The first holder (3) is supported by the second holder (4) through the support (5) to restrict at least movement of the first cable (11) in a pulling direction of the first cable (11).Type: ApplicationFiled: May 17, 2021Publication date: August 17, 2023Inventors: Ryota TOMIYAMA, Hideki KAWAHARA, Hideki OKA, Kouji KAKIUCHI, Mizuki YAGURA, Shinichi NAKAMURA

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
