This application relates to a photovoltaic connector with more stable contact, belonging to the field of photovoltaic connector technology. It includes a male plug and a female plug, with a connection module between them. The tool-free wiring mechanism of this application utilizes a fixed ring, turntable, worm gear, worm, knob, cover plate, sleeve block, and sleeve rod for transmission cooperation. This allows the sleeve rod to drive the male and female copper-plated tin-plated inner cores to clamp the cable without the need for wire clamping pliers, solving the problem of not being able to replace cables on-site due to lack of tools. Simultaneously, the L-shaped connecting plate, limiting hole, connecting block, locking rod, fixing plate, and telescopic spring of the connection module achieve precise docking and automatic locking of the male and female plugs. A lever further reduces disassembly difficulty, and a deformation groove forms a three-lobed structure for the male and female copper-plated tin-plated inner cores, increasing the contact area with the cable and adapting to different wire diameters. The clamping claw assembly and the loosening tightening nut provide secondary reinforcement of the cable, preventing it from falling off and allowing for reuse.
