Description

TECHNICAL FIELD

[0001] The utility model belongs to the connecting structure, especially relate to a waterproof electric connection mechanism. BACKGROUND

[0002] With the rapid development of modern science and technology, various electronic devices have been widely used in people's daily life, industrial production and many fields. In the running process of these electronic devices, electrical connection between different devices is often realized through an electric connection mechanism to ensure the normal operation of data transmission, power supply and other functions.

[0003] However, in many practical application scenarios, the electric connection mechanism often faces the problem of insufficient waterproof performance: there is usually a gap between the male end and the female seat end, and water vapor or liquid can easily penetrate into the connection part through the gap, causing internal circuit dampness, short circuit and other problems, which seriously affects the normal operation and service life of the equipment.

[0004] In some special environments with high waterproof requirements, such as outdoor electronic devices, underwater operation equipment, medical electronic devices, etc., the problem of poor waterproof performance of traditional electric connection mechanism is more prominent. For example, when an outdoor monitoring camera is attacked by rain, if the waterproof performance of the electric connection part is poor, it may cause image transmission interruption, equipment damage and other serious consequences; when an underwater robot is conducting deep-sea exploration, if its electric connection mechanism cannot effectively prevent water, it will not only affect the progress of the exploration task, but also may cause irreversible damage to the equipment.
