Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic connector technology, and more specifically, it relates to a quick-connect self-locking high-reliability photovoltaic connector. Background Technology

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, solar photovoltaic power generation, as a clean and renewable energy form, has received widespread attention and application. In photovoltaic power generation systems, photovoltaic connectors, as important electrical interfaces connecting key components such as photovoltaic modules, inverters, and energy storage devices, directly affect the power generation efficiency and service life of the entire photovoltaic system due to their stability and reliability.

[0003] Existing photovoltaic connectors generally have certain limitations in their design. Their internal structures for fixing cables often lack flexibility and adaptability. When faced with cables of different specifications and diameters, these connectors struggle to achieve effective clamping and fixing. The clamping components of some connectors have fixed dimensions and cannot be adjusted according to the actual thickness of the cable. This can result in excessive clamping force for thicker cables, causing damage to the cable insulation layer. Conversely, for thinner cables, the clamping force may be insufficient or loose, affecting the stability of the electrical connection. Utility Model Content

[0036] The specific usage and function of this embodiment are as follows:

[0037] In this invention, the positive and negative cables are passed through the elastic ring 405 and the auxiliary sleeve 404 respectively, and then the cable ends are placed between the conductive clamps 304. The threaded sleeve 403 is rotated using the threaded structure, causing it to move towards the retaining ring 402.

The conductive clamps 304 move linearly through the conductive seat 303 and the guide rod 302.

Do not connect the conductive post A103 and conductive post B202; then slide the elastic self-locking plate 201 into the self-locking groove 102, so that the end of the elastic self-locking plate 201 moves in the opposite direction of the inclined side through its own inclined plate; so that the connecting post 203 slides into the conductive post A103. When the sealing ring 104 slides into the sealing groove 205, the elastic self-locking plate 201 bounces up and resets by its own elastic force, so that the end of the elastic self-locking plate 201 fits against the side wall of the auxiliary groove 101, so that the negative terminal connector 1 and the positive terminal connector 2 are fixedly connected, and the conductive post A103 and conductive post B202 are connected.
