Description

Socket with insulated and heat conductive parts

This creation relates to a socket, especially a socket with an insulated heat conductor.

In order to improve the safety of electrical connectors, many electrical connectors are combined with temperature sensing, overheat protection, overload protection and other designs.

This case is mainly for the firewire of the switch unit (or socket unit) connected to the overload protector in the extension cord socket. The conductive sheet is suitably extended; the overload protector has a power input sheet exposed to the shell member, and the inner end of the power input sheet is fixed with a temperature sensitive sheet which is overheated and warpable, and the other end of the temperature sensing sheet is a free end. The end has a contact, and the overload protector is further provided with a channel, and the aforementioned live wire conductive piece is adapted to extend into the channel and be in contact with the contact of the temperature sensing sheet.

However, in the previous case of 505334, the temperature sensor of the overload protector is connected to the live wire conductive piece. When the working temperature of the live wire conductive piece is too high, the overload protector can automatically form an open circuit, but if the overheating is neutral, the conductive line is electrically conductive. The film could not respond in time.

The safety switch is connected to the neutral terminal or the live terminal. When the safety switch receives the thermal energy and heats up to a dangerous temperature, the safety switch will be switched from a power-on state to a power-off state.

Further, the neutral terminal and the live terminal each comprise a second conductive elastic piece, and the insulating heat conducting member has the foregoing gap between the adjacent conductive elastic sheets.

Further, the utility model further comprises a mounting seat, wherein the neutral wire terminal, the live wire terminal and the insulating heat conducting member are mounted on the mounting seat.

1. The safety switch is usually used to connect to the live wire to control the flow or interruption of the live current.
