Abstract

An electronic clinical thermometer includes an elongated shell, a metal tip in one end of the shell, a circuit board mounted within the shell, a temperature sensor mounted in the top of the metal tip for producing a signal indicative of the temperature of the metal tip, two conducting wires connected in parallel between the temperature sensor and the circuit board, and a heat insulator stuffed in the metal tip to hold down the temperature sensor and the conducting wires against the inside wall of the metal tip and to present a temperature loss during measuring of the electronic clinical thermometer.

Claims

1. An electronic clinical thermometer comprising an elongated shell, a metal tip installed in one end of said shell, said metal tip having an inside wall, a circuit board mounted within said shell, a temperature sensor mounted in a top of said metal tip and fixedly secured to the inside wall of said metal tip with a drop of glue for producing a signal indicative of the temperature of said metal tip, and two conducting wires connected in parallel between said temperature sensor and said circuit board, wherein a heat insulator is stuffed in said metal tip to hold down said temperature sensor and said conducting wires, keeping said temperature sensor and said conducting wires in contact with the inside wall of said metal tip.

2. The electronic clinical thermometer as claimed in claim 1, wherein said conducting wires are arranged in parallel and attached to the inside wall of said metal tip at one side.

3. The electronic clinical thermometer as claimed in claim 1, wherein said conducting wires are extended from said temperature sensor in reversed directions and attached to the inside wall of said metal tip at two sides.

4. The electronic clinical thermometer as claimed in claim 1, wherein said heat insulator is a tubular plug member fitted into said metal tip to hold down said temperature sensor and said conducting wires.
