Description

Technical Field

[0001] This utility model relates to a flat wire photovoltaic connector, belonging to the field of photovoltaic technology. Background Technology

[0002] With social development and improved living standards, solar energy, as a clean energy source, has been widely applied. Solar photovoltaic (PV) technology converts solar radiation into electrical energy through photoelectric conversion devices. These devices typically utilize the photovoltaic effect of semiconductor devices. Besides photovoltaic cell modules, PV power generation also requires PV connectors to transmit power. Currently, PV connectors are primarily cable connectors, installed on the positive and negative leads of the PV cell modules, mainly used to connect the modules and thus transmit electrical energy. Structurally, PV connectors are mainly divided into male connectors and female connectors for mating with them. Because PV connectors are used in harsh outdoor environments for extended periods, typically over ten years, the reliability and safety requirements for these connectors are very high. Existing PV connectors have limited structural strength, which is not conducive to long-term use. Therefore, due to the long operating time and harsh environment of solar power plants, the stability and reliability requirements for connectors are extremely high.

[0003] Chinese patent CN218160952U discloses a photovoltaic connector, which includes a male plug and a female plug connected to the male plug. The male plug includes a rigid snap-fit ​​male shell and a first soft protective sleeve fitted on the rigid snap-fit ​​male shell. The rigid snap-fit ​​male shell includes a first cable sleeve, a snap-fit ​​plate disposed at one end of the first cable sleeve, and a snap-fit ​​piece disposed on the snap-fit ​​plate. The first soft protective sleeve is fitted on the first cable sleeve. The female plug includes a rigid snap-fit ​​female shell and a second soft protective sleeve fitted on the rigid snap-fit ​​female shell. The rigid snap-fit ​​female shell is provided with a snap-fit ​​groove for the snap-fit ​​piece to be inserted. This connector has a strong structural stability and is not easily damaged, but it lacks good sealing performance, which can easily lead to a decrease in connection performance during long-term use.
