Power cord having thermal sensor

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.

2. The power cord of claim 1 ,

wherein the thermal sensor is configured to detect a temperature around a tip of the fitting portion, and

wherein the enclosure is in contact with the tip of the fitting portion while the enclosure covers all over the tip of the fitting portion.
