Analysis and preventive measures of common faults in electrical connection part of electronic endoscope

1. Corrosion and rust on the electrical connection will cause abnormal phenomena such as flickering and jittering of the image, and serious damage to the CCD. The main cause of this failure is: the electrical connection part is not covered with a waterproof cap during cleaning and disinfection, and the electrical connection port is connected to the image processing center when it is stained with water. The preventive measures are as follows: the mirror should be covered with a waterproof cap when cleaning and disinfecting, and then the mirror body must be wiped with a dry cloth and the electrical interface points must be blown dry with an air gun.
2. The electrical connector and the connection seat are inserted forcibly when the bayonet is not aligned, causing the metal needle in the electrical connector to break, causing abnormal or no image display. When electrical connection, press the corresponding position to fasten the interface to avoid this failure.
