Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and more specifically, to a photovoltaic control connector with a quick-change mating connector. Background Technology

[0002] Currently, in the operation of photovoltaic systems, the inverter, as one of the core components, needs to be electrically connected to other components through connectors to ensure stable power transmission and normal system regulation. With the rapid development of the photovoltaic industry, the application scenarios for connectors are becoming increasingly diverse. Different manufacturers' photovoltaic equipment has different interface requirements for connectors, leading to frequent on-site testing and installation operations.

[0003] In existing technologies, photovoltaic control connectors on the market are generally one-piece molded structures that cannot be disassembled. Because the mating interfaces of products from different manufacturers are not standardized, on-site personnel need to carry large quantities of connector materials of different specifications to the site for verification to find compatible mating interface materials during testing and installation. This process is not only time-consuming but also increases the cost and difficulty of transporting materials. Furthermore, the PCBA circuit board in the one-piece connector cannot be shared between different interface connectors. When different interfaces are required, the entire connector must be replaced, resulting in a significant waste of PCBA circuit boards and connector materials. This increases operating costs and does not meet the development requirements of energy conservation and environmental protection. Utility Model Content

[0014] This utility model has the following beneficial effects: This connector comprises three independent modules: a mid-shell module, a plug module, and a socket module, all of which can be detachably plugged in. This allows for rapid on-site replacement of the appropriate plug or socket module to meet the interface requirements of different scenarios, eliminating the need to carry large quantities of complete connector materials. This simplifies the testing and installation process, saving time and material costs. The main control module within the mid-shell module can be used with plug and socket modules of different interfaces, enabling the sharing of PCBA circuit boards.

[0023] like Figures 1 to 4 As shown, this utility model embodiment provides a photovoltaic control connector with quick-change connectors, including a middle shell module 1, a plug module 2, and a socket module 3. The connector allows for detachable insertion of the middle shell module 1 with the plug module 2 and socket module 3, effectively enabling quick replacement of the plug module 2 and socket module 3 based on the middle shell module 1. This allows for rapid plug or socket replacement to adapt to different interface requirements. Simultaneously, a spring pin connection assembly ensures precise and stable contact between the modules, and the elastic latching part a between the plug or socket and the middle shell module 1 enables efficient locking or unlocking, simplifying the assembly and disassembly process and improving overall functionality. Specific settings are as follows: Please refer to... Figures 1 to 2 The middle shell module 1 includes a middle protective shell 11, a PCBA circuit board 12, and a limiting buckle 13. One end of the PCBA circuit board 12 is detachably and fixedly connected to the limiting buckle 13, and the PCBA circuit board 12 is located inside the middle protective shell 11. The limiting buckle 13 has an elastic buckle, and the limiting buckle 13 is detachably and fixated to the inner wall of the middle protective shell 11 through its elastic buckle, so as to stably place the PCBA circuit board 12 inside the middle protective shell 11, prevent the PCBA circuit board 12 from shifting during use, and ensure the functional stability of the middle shell module 1.

[0024] Please continue to refer to this. Figure 2 The plug module 2 includes a plug housing 21 and a plug spring pin connector 22. The plug spring pin connector 22 is fixedly assembled inside the plug housing 21, and the plug spring pin connector 22 is electrically connected to one end of the PCBA circuit board 12 to realize the electrical connection between the plug module 2 and the middle shell module 1, ensuring stable transmission of power and data. Specifically, the plug spring pin connector 22 can be, but is not limited to, a POGOPIN connector, which is configured with at least two contact points. Each contact point is elastically connected to the PCBA circuit board 12 of the middle shell module 1. This multi-contact design improves the reliability of the electrical connection between the plug module 2 and the middle shell module 1, and reduces the risk of connection interruption caused by rigid contact through elastic connection.

[0025] As a preferred embodiment, the outer wall of the plug housing 21 is fixedly provided with a foolproof key, which serves as a foolproof guide when the plug module 2 is plugged into the middle shell module 1, so as to avoid damage to the components or failure of the connection due to incorrect plugging direction.

The socket spring pin connector 32 is fixedly assembled inside the socket housing 31, and the socket spring pin connector 32 is electrically connected to the other end of the PCBA circuit board 12 to realize the electrical connection between the socket module 3 and the middle shell module 1, ensuring stable transmission of system control signals and power. Specifically, the socket spring pin connector 32 can be selected, but is not limited to, a POGOPIN connector, and the socket spring pin connector 32 has at least two main control contact points 321. The at least two main control contact points 321 are respectively elastically connected to the PCBA circuit board 12 of the middle shell module 1 to enhance the electrical connection stability between the socket module 3 and the middle shell module 1 and further optimize the contact performance.

[0027] Please refer to Figure 4 The plug housing 21 of the plug module 2 and the socket housing 31 of the socket module 3 are both connected to the middle protective shell 11 of the middle shell module 1 by a detachable elastic snap-fit ​​part a. This allows the middle shell module 1 to be quickly snapped and fixed to the plug module 2 and the socket module 3 by the elastic snap-fit ​​part a. Pressing the elastic snap-fit ​​part a causes deformation, which allows the middle shell module 1 to be quickly unlocked from the plug module 2 and the socket module 3 without the need for tools, thus improving the ease of operation.

[0028] Please continue to refer to this. Figure 2The plug module 2 and the socket module 3 are respectively equipped with waterproof sealing rings 4 at their insertion positions with the middle shell module 1.
