Wire box for photovoltaic module

Provided is a wire box for a photovoltaic module. Relates to the photovoltaic technical field. The device comprises a box body and a sleeve pin. The box body is provided with a module cavity for installing a diode module, and the side part is provided with a leading-out part which extends outwards; the sleeve pin comprises a sleeve part and a pin part which are connected in sequence; the sleeve part is fixedly arranged in the lead-out part and is matched with the connector of the connecting wire; and the pin part extends into the module cavity and is fixedly connected with the diode module in a welding manner. The sleeve pin is combined with the box body through an injection molding process, so that a photovoltaic connector part does not need to be additionally assembled in the production and manufacturing of the photovoltaic junction box. The use cost of cables and connector materials in a photovoltaic module connection system can be greatly reduced, and the connection efficiency between the photovoltaic mod
