Photovoltaic junction box

Abstract

The invention relates to a photovoltaic junction box. The photovoltaic junction box comprises a box body, a box cover, terminals and a cable, wherein the box cover is matched with the box body, the terminals are installed inside the box body, and the cable is electrically connected with the terminals. The cable comprises a plurality of core wires. The box body comprises an installation part, a side part and a cavity, wherein the side part extends upwards from the installation part, the cavity is formed by the installation part and the side part, the side part comprises a back wall and a cable groove which penetrates through the back wall, and the core wires are led from the exterior of the photovoltaic junction box into the cavity through the cable groove. The cable further comprises a wrapping part which wraps the core wires into a whole, the wrapping part and the core wires pass through the cable groove and enter the cavity to be electrically connected with the terminals. Due to the fact that the wrapping part which wraps the core wires and is electrically connected with the terminals is arranged, the core wires cannot be scattered when the core wires penetrate into the photovoltaic junction box from the exterior of the photovoltaic junction box through the cable groove, the core wires can be installed conveniently, and the efficiency for assembling the photovoltaic junction box is improved.

Description

technical field [0001] The invention relates to a photovoltaic junction box. Background technique [0002] The inexhaustible solar energy is being favored by more and more people. Solar photovoltaic power generation has been included in the new energy development and utilization plan by many countries, and the application volume is expanding year by year. Currently commonly used photovoltaic junction boxes include a box body, a box cover matched with the box body, and cables electrically connected to the terminals. The cable is electrically connected to the terminal through the core wire. When the core wire and the terminal are electrically connected, it is generally necessary to pass through the cable slot on the box and enter the photovoltaic junction box. Since the core wire in the cable is generally There are many wires, so when threading into the cable trough, the core wires often have burrs or spread out and cannot fully penetrate the cable trough, which brings certa...

AI Technical Summary

Problems solved by technology

The cable is electrically connected to the terminal through the core wire. When the core wire is electrically connected to the terminal, it generally needs to pass through the cable groove on the box body and enter the interior of the photovoltaic junction box. Since the core wire in the cable is generally There are many wires, so when passing through the cable groove, the core wires often have burrs or scatter and cannot be completely inserted into the cable groove, which brings certain difficulties to threading, thus affecting the assembly efficiency of the photovoltaic junction box
