T-shaped structure connector for photovoltaic inverter

Abstract

The invention discloses a T-shaped structure connector of a photovoltaic inverter, which includes a male end and a female end. The male end is provided with a shell composed of an upper cover and a lower cover. In the cavity of the bus, the upper cover is provided with the jack corresponding to each male terminal, and the inlet, outlet and jack at both ends of the housing are respectively provided with waterproof parts; the female terminal is provided with The shell is composed of a protective cover, a main body and a nut. The main body is provided with a connection hole. The protective cover is sleeved on the outside of the female end. The nuts are threaded, and the front and rear ends of the protective cover are respectively provided with front and rear waterproof parts. The present invention constitutes the shell of the male end and the outer shell of the female end by clamping, which saves the glue-covering process, and realizes the connection of the core wire by directly plugging the tuning fork terminal with the core wire, eliminating the need for peeling and other processes, and the assembly is more efficient. Convenience and improved production efficiency.

Description

technical field [0001] The invention relates to a photovoltaic connector, in particular to a T-shaped structure connector of a photovoltaic inverter and a connection structure between a bus and a branch line. Background technique [0002] The direct current generated by the photovoltaic cell module is transformed into alternating current by the photovoltaic inverter and fed to the grid. During this process, the current in each branch cable needs to be converged to the main cable. The bus end) and the female end (branch end), the male end leads out each core wire in the bus separately, the female end is provided with a terminal electrically connected to each core wire, and the male end and the female end are plugged together to form a T-shaped structure The form of electrical connection between the branch line and the bus. [0003] In the current technology, it is generally necessary to strip the lead wires from the bus, wind the lead wires on the exposed core wires, and the...

Problems solved by technology

Due to the use of metal terminals 114 to lead wires, compared with manual winding, the connection stability and firmness have been greatly improved, but the complexity of the operation has not been significantly improved, and manual participation is still required, so the processing efficiency is not high. be improved and affect the progress of mass production

In addition, whether it is a male end or a female end, it is necessary to set an adhesive layer on the outer layer, that is, to use the adhesive layer to ensure the waterproofness of the connector, but this process will inevitably require mold opening, which increases production costs on the one hand. On the other hand, the process is complicated, which reduces the assembly efficiency of the entire set of connectors and affects the improvement of production volume.
