Title:
COMPUTER BOARD AND REFRIGERATING AND FREEZING APPARATUS WITH SAME
Document Type and Number:
WIPO Patent Application WO/2021/223491
Kind Code:
A1
Abstract:
A computer board and a refrigerating and freezing apparatus with same. The computer board comprises a circuit board, a battery for supplying power to the circuit board, a power supply lead connected to a positive electrode and a negative electrode of the battery, and a conductive metal piece, and an insulating sheet, wherein the power supply lead comprises a first lead section and a second lead section; one of the first lead section and the second lead section is connected to the positive electrode of the battery, and the other is connected to the negative electrode of the battery; the conductive metal piece is connected to the end of the first lead section that is not connected to the battery; the end of the second lead section that is not connected to the battery is provided with an exposed conductive portion, and the conductive metal piece covers the outer side of the conductive portion; and the insulating sheet can be operably placed between the conductive metal piece and the conductive portion so as to isolate the conductive metal piece from the conductive portion, or can be operably extracted from between the conductive metal piece and the conductive portion so as to connect the conductive metal piece to the conductive portion. Two lead sections are of the same potential, thereby avoiding the impact of condensation on a circuit.
