A plug-in outer-lead photovoltaic assembly junction box and a solar photovoltaic assembly string. The junction box comprises a junction box body (2) with a built-in wiring line (1), and a connection wire (3). Each of two ends of the connection wire (3) is separately provided with a plug (4). The junction box body (2) is provided with a negative electrode socket (5) connected to the negative electrode of the wiring line (1) and a positive electrode socket (6) connected to the positive electrode of the wiring line (1). The connection wire (3) is detachably plugged in the negative electrode socket (5) or the positive electrode socket (6) by means of the plugs (4). The solar photovoltaic assembly string comprises a plurality of photovoltaic assemblies (7), and each of the photovoltaic assemblies (7) is provided with a junction box, and the junction box is the foregoing plug-in outer-lead photovoltaic assembly junction box. The length of the wire can be effectively reduced, electric energy loss due to the excessive length of the wire is reduced, the system efficiency of the photovoltaic power station is improved, connection among assemblies is simplified, wire connection points can be reduced, contact resistance is reduced, and hidden fault points can be reduced. |
