Title:
SENSOR, BATTERY AND ELECTRICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/123740
Kind Code:
A1
Abstract:
The embodiments of the present application relate to the technical field of electronic component manufacturing, and relate in particular to a sensor, a battery and an electrical device. The sensor comprises a heat conduction seat, a sensing unit and a circuit board. The circuit board is arranged on the heat conduction seat, and the surface of the circuit board facing away from the heat conduction seat is provided with a first conductive contact and a second conductive contact; the sensing unit is respectively electrically connected to the first conductive contact and the second conductive contact; and the circuit board is further provided with a drainage channel, the drainage channel being located between the first conductive contact and the second conductive contact. When the temperature of the surrounding environment of the sensing unit fluctuates, moisture in the air is liquefied into liquid drops. When the liquid drops attach to a surface of the sensing unit, the liquid drops are discharged along the drainage channel on the circuit board due to the action of gravity, preventing the sensing unit from short-circuiting due to liquid drops connecting the first conductive contact and the second conductive contact.
