Abstract
A power strip includes a power plug and an outlet connected to the power plug through a power cord. The power plug has a plugging face and at least one power pin disposed on the plugging face. The power plug includes a first thermal cut-off device, which has a first thermal sensing pin exposed on the plugging face. The outlet has at least one set of apertures. The first thermal cut-off device is in electrically connection with a power output wire of the power plug. The first thermal cut-off device cuts off the power transmission between the power plug and the outlet when the temperature of the plugging face exceeds a first determined temperature.
Claims10
A power strip, comprising:
- a power plug having a plugging face and at least one power pin disposed on the plugging face, wherein the power plug includes a first thermal cut-off device disposed therein, the first thermal cut-off device has a first thermal sensing pin exposed on the plugging face;
- and
- an outlet having at least one set of apertures and connected to the power plug through a power cord;
- wherein the first thermal cut-off device is in electrically connection with a power output wire of the power plug, and when the temperature of the plugging face exceeds a first determined temperature, the first thermal cut-off device cuts off the power transmission between the power plug and the outlet.
A power plug, comprising:
- a main body having a plugging face and at least one power pin disposed on the plugging face;
- and
- a thermal cut-off device disposed inside the main body, wherein the thermal cut-off device has a thermal sensing pin exposed on the plugging face;
- wherein the thermal cut-off device is electrically connected between the power pin and a power output wire of the power plug, and when the temperature of the plugging face exceeds a determined temperature, the thermal cut-off device cuts off the power transmission between the power pin and the power output wire.
An outlet adapted for a power strip, the power strip having a power plug, the outlet comprising:
- a main body having at least one set of apertures and connected to the power plug through a power cord, wherein the outlet has at least one conductive sheet disposed inside the main body;
- and
- a thermal cut-off device disposed inside the main body and electrically connected between the conductive sheet and a power input wire, wherein the thermal cut-off device has a thermal sensing pin in contact with the conductive sheet;
- wherein the thermal cut-off device cuts off the power transmission between the conductive sheet and the power input wire when the temperature of the conductive sheet exceeds a determined temperature.
