Power cord having thermal sensor

摘要

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.

1. A power cord, comprising:
a plug comprising blades configured to be inserted into blade insertion holes of an electrical outlet, respectively, and a thermal sensor configured to detect a temperature; a load connector configured to be connected to a load; and a cut-off switch configured to stop electric power from being supplied to the load connector from the blades when a temperature detected with the thermal sensor is higher than a prescribed temperature, wherein the plug further comprises: 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, wherein the core includes: an inner frame retaining the blades; and a case, wherein the case is shaped like a cylinder having a base on a front side and an opening on a rear side, and the base is provided with through holes into which the blades are inserted, wherein the base of the case is provided with a fitting hole, and the thermal sensor has a fitting portion fitted into the fitting hole, wherein the thermal sensor penetrates through the base of the case, and a tip of the fitting portion of the thermal sensor protrudes from the base and is buried in contact with the enclosure.
