Problems solved by technology

[0003] In the current photovoltaic new energy field, the data collection module of the inverter is basically pre-programmed on the PCBA board with software, and the programming interface is pre-placed on the PCBA board. This method has the disadvantage that the software is not easy to iteratively upgrade, so For pre-writing the software into the memory card, the writing of the software is realized by plugging the memory card into the interface, but because the existing interface is set on the box, when the memory card is plugged into the interface, the memory card will be dropped. In order to prevent the memory card from falling into the box, it is usually necessary to remove the entire inverter shell to achieve the effect of safely replacing the memory card. Since there are many precision-connected lines inside the box, resulting in When taking out the memory card, it is easy to cause damage to the working environment of the inverter, thus easily causing damage to the inverter

Abstract

According to the technical scheme, the memory card external connection structure applied to the inverter is characterized in that the memory card external connection structure comprises an external connection seat and an internal connection seat, and the external connection seat and the internal connection seat are arranged on the outer side and the inner side of a box body respectively; the inner connecting seat is connected with the box body through the butt joint assembly; the external connection seat is connected with the internal connection seat through the external connection assembly; the box body is provided with an external connection seat, the expansion assembly is provided with a plugging port for plugging a memory card, the plugging port is arranged on the external connection seat, one end, far away from the plugging port, of the expansion assembly is connected with an inverter arranged in the box body, and the box body is provided with a mounting hole for the expansion assembly to penetrate through. The memory card external connection structure applied to the inverter has the advantages that the inverter is not damaged, and the memory card can be conveniently plugged and unplugged.

Description

technical field [0001] The present invention relates to the technical field of inverter structure, and more specifically relates to an external connection structure of a memory card applied to an inverter. Background technique [0002] An inverter is a converter that converts DC power into constant frequency and constant voltage or frequency modulation and voltage modulation AC power. It consists of inverter bridge, control logic and filter circuit. Inverters are widely used in various fields of life. With the increasing emphasis on new energy, inverters are also widely used in the field of photovoltaic new energy. [0003] In the current photovoltaic new energy field, the data collection module of the inverter is basically pre-programmed on the PCBA board with software, and the programming interface is pre-placed on the PCBA board. This method has the disadvantage that the software is not easy to iteratively upgrade, so For pre-writing the software into the memory card, t...
