Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, and in particular to a press-type photovoltaic connector. Background Art

[0002] As we all know, photovoltaic connectors are electrical connectors specially used to connect solar panels and electrical equipment in solar photovoltaic systems. They are usually waterproof, corrosion-resistant and weather-resistant, and can operate stably for a long time in harsh outdoor environments. The design of photovoltaic connectors takes into account factors such as easy installation, high efficiency and low loss to ensure the safety, reliability and performance of photovoltaic systems. Common photovoltaic connector types include MC4, MC3, etc. They connect solar panels through reliable plug-in methods to form a complete circuit and realize the collection and utilization of solar energy.

[0003] However, traditional photovoltaic connectors usually require the use of tools to connect the male plug and the female plug, which may require additional steps and skills, increasing the complexity of the installation process. Especially when installing a large number of photovoltaic connectors, this may increase the difficulty of operation. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a push-type photovoltaic connector. When the photovoltaic connector is in use, the male plug is clamped with the female plug, and the elastic clamping block is bent downward by the force. At this time, the pressing pad is pushed to drive the internal limit spring to be compressed, so that the front end of the elastic clamping block is clamped with the clamping hole, so that the male plug and the female plug can be firmly connected together and are not easy to loosen or fall off, thereby ensuring the reliability and stability of the connection. At this time, the pressing pad is released to allow the limit spring to restore the force to drive the limit ring to rebound, so that it rests against one side of the clamping block. The action of the limit spring can ensure that the front end of the elastic clamping block is completely clamped with the clamping hole, avoiding loosening or misalignment of the plug during the connection process, thereby improving the safety of the connection. When it needs to be opened, the upper and lower ends of the pressing pad are pressed, and the clamping block is disengaged from the clamping hole, which facilitates the removal of the male plug and the female plug.

[0012] Furthermore, the upper and lower ends of the outer wall of the limit frame are provided with snap-fit ​​holes, and the front ends of the elastic snap-fit ​​blocks are snap-fitted with the snap-fit ​​holes;
