Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a waterproof signal connector. Background Art

[0002] With the rise of new energy light-duty transportation vehicles (e-bikes, electric scooters, electric tricycles, and driving vehicles at home and abroad), the large-scale application of low-capacity lithium batteries, and the increasing number of signal connectors for vehicle systems, the terminals of such connectors generally have at least two terminals to achieve signal transmission between various electronic components. Vehicle applications usually involve a male or female connector harness connected to an electronic component, and then connected to a male or female connector harness connected to another electronic component.

[0003] Since new energy vehicles use power, the vehicle's connector must be waterproof while ensuring a stable connection to avoid leakage or short circuits that could cause damage to people. A common waterproof method is to add waterproof parts to the connector, but this method is less efficient during connection, more complex in structure, and more expensive to manufacture.
