Description

Waterproof connector

Technical Field

The utility model relates to a waterproof technology field especially relates to a waterproof connector.

Background

Charging and signal transmission are basically necessary functions of electronic products, and are usually realized by a connector connection mode. However, a large amount of electronics of the current electronic products have requirements on waterproof performance, so that the connector is required to have waterproof function; meanwhile, in order to realize the functions of charging and electric signals, the connector usually comprises a power supply PIN, a signal + PIN, a signal-PIN and a grounding PIN. In practical application, a small amount of conductive liquid such as water or sweat often exists between power supply PIN, signal + PIN, signal-PIN and grounding PIN, and the situation is particularly common on bracelets, mobile phones and Bluetooth earphones.

When conductive liquid such as water or sweat exists between the PIN needles, the PIN needles are communicated through the water or the sweat, and the PIN needles are easy to generate electrolysis to corrode the PIN needles when electrified. Since the electronic products are all developed toward miniaturization, it is difficult to prevent the electrolytic corrosion phenomenon by increasing the separation of the PIN PINs.

Thus, the prior art is deficient and needs improvement.
