Junction box for solar photovoltaic module

Abstract

The invention relates to a junction box for a solar photovoltaic module and belongs to the technical field of electrical connectors. The junction box for the solar photovoltaic module comprises a box seat and a box cover body and is characterized in that a box cover seat is arranged at the middle position of a box seat body; a cavity is arranged in the middle of the box cover seat; a diode, a first sinking electrode and a second sinking electrode are arranged inside the cavity; an end face is formed at the outer edge of a wall body of the box cover seat; positive and negative lead terminals are formed at both sides of the bottom of the box seat body; a plug bush is arranged in the positive lead terminal and is connected with one end of the diode; a plug is arranged in the negative lead terminal and is connected with the other end of the diode; the first sinking electrode is arranged in a first positioning ring electrically connected with the plug bush; the second sinking electrode is arranged in a second positioning ring electrically connected with the plug; and the bottom surface of the box seat body is provided with a glue coating layer. The invention has the advantages that thejunction box is suitable for automatic stream line operation; the sinking electrodes are avoided being inclined or distorted due to an external force; the junction box is convenient for a manipulatorto operate; and the junction box is convenient to install and use and has long service life.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and in particular relates to a junction box for solar photovoltaic modules. Background technique [0002] The scarcity to exhaustion of non-renewable energy sources such as coal and oil, and the deteriorating ecological environment have made energy issues increasingly become a bottleneck restricting the development of the international society and economy, and at the same time greatly promoting the rapid development of the solar photovoltaic industry. Since 1996, the demand for solar photovoltaic cells in the world has grown at an annual rate of 30%. In 2000, the growth rate of international solar photovoltaic cells reached 38%, and in the past two years it reached 50%. The market demand continues to expand. In order to meet the market needs, the photovoltaic module process is continuously optimized, and efficient automatic production has been introduced into the first production li...

The market demand continues to expand. In order to meet the market needs, the photovoltaic module process is continuously optimized, and efficient automatic production has been introduced into the first production line. Disclosed in CN201562929U, a nut is provided on the lead end of the junction box, one end of the cable is connected to the nut, and the other end of the cable is connected to the cable connector. This cable and the cable connector are arranged in the junction box The in vitro assembly method with wires cannot be applied to automated production line equipment; at the same time, the junction box and the manipulator cannot cooperate with each other, which cannot meet the market's demand for automated production
