Description

The present invention relates to an outlet, and more particularly, to an outlet provided with an insulating heat conducting member.

  To increase the safety of electrical connectors, many electrical connectors are combined with designs such as temperature sensors, overheat protection, overload protection and the like.

  As a related plan, there is “Overload protector of extension outlet” in the registration of utility model registration No. 505334 in the Republic of China. This plan is mainly a switch unit (or outlet) connected to the overload protector in the extension outlet. The unit's live conductor piece is properly extended, and the overload protector is provided with a power input piece exposed to the outside of the housing, and the temperature sensitive piece that warps when overheated is connected to the inner end of the power input piece. The other end of the hot piece is a free end, the end is provided with a contact point, the overload protector is further provided with a groove portion, the hot wire conductive piece is moved into the groove portion to be positioned, and the temperature sensitive piece is contacted. Can be in normal contact with the spot.

  In the above-mentioned prior design of No. 505334, the temperature sensitive piece of the overload protector is connected to the live conductive piece, and the overload protector automatically turns off the power when the operating temperature of the live conductive piece is too high. However, when the overheated part is a neutral conductive piece, it cannot be reacted immediately.

  In addition, there is “Electrical Connector and its Temperature Detection Mechanism” of Republic of China Patent Publication No. I547034. This is mainly because the heat conductor is connected to the first pin and the second pin at the same time, and the heat energy is quickly and effectively supplied. It can be transmitted to a temperature sensor in the heat conductor.

  The above-mentioned I547034 thermal conductor can receive the thermal energy of the first pin and the second pin, but the thermal conductor is disposed on the electrical connector of the plug, and other elements when applied to other electrical connectors. However, it has a relatively high practicality.
