A cable connection device includes a first holder, a second holder and a support. The first holder is configured to hold a tip part of an end of a cable. The second holder is configured to hold an intermediate part of the end. The support is configured to support the first holder. The second holder is fixed with respect to a power feed control device body. The first holder is supported by the second holder through the support to restrict at least movement of the cable in a pulling direction of the cable.

Cable connection device and power feed control device

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.

Power cord

The first molded part and the second molded part are molded products of synthetic resin materials. The first molded part is made of a synthetic resin material having a higher creep resistance than a synthetic resin material forming the second molded part. The second molded part is made of a synthetic resin material higher than a synthetic resin material forming the first molded part in adhesion to a material forming the receiver contact.

Charging connector

A power cord includes a plug. The plug includes plural blades to be respectively inserted into plural blade insertion holes of an electrical outlet for connection. The plug further includes plural thermal sensors provided so that each of the plural blades corresponds to a thermal sensor. The power cord further includes a communication circuit that is configured to notify a control circuit of a load, when a temperature detected by any one of the plural thermal sensors is higher than a predetermined temperature.

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.

Power cord having thermal sensor

A power cord includes a plug having blades configured to be inserted into blade insertion holes of an electrical outlet, respectively. The power cord further includes thermal sensors provided for the blades one each. When a temperature detected with any of the thermal sensors is higher than a prescribed temperature, electric power is stopped from being supplied to a load from the blades.

A plug includes male contacts, a core and an envelope. Each of the male contacts includes a stopper. The core includes a first member and a second member. The stoppers are in contact with the first member and the male contacts are in contact with the second member, so that the male contacts are prohibited from being displaced with respect to the core in a first direction along which the male contacts protrude from an end face of the core.
