Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a photovoltaic connector with multiple waterproof structures. Background Technology

[0002] Photovoltaic connectors generally refer to electrical connectors used in solar photovoltaic systems. In photovoltaic systems, these connectors are used to connect solar panels to each other, and to connect the panels to inverters or other equipment. These connectors must be able to withstand long-term outdoor use, resisting sun, rain, and other harsh weather conditions.

[0003] Existing photovoltaic connectors still have the following problems when in use: their outer ends are usually coated with a waterproof coating, and their interfaces are usually designed with an optimized interface. After the interface part of the connector is optimized, it can ensure that a tight connection is maintained during insertion and removal to prevent moisture from entering through the interface. However, when the connector interface is not inserted into the photovoltaic connection component, its interface is exposed and cannot be waterproof. Utility Model Content
