The solar junction box is sealed with silica gel

1. Industry introduction

The junction box of solar cell module is the connector between the solar cell square composed of solar cell module and the solar charging control device. The main function is to connect the power generated by solar cell with the external circuit.The junction box is glued together with the back plate of the module by silica gel, and the lead out line in the module is connected with the internal line in the junction box, and the internal line is connected with the external cable, so that the module and the external cable lead through.

2. Process characteristics

The shell of the solar junction box is coated with silica gel. The coated track is a sealed track evenly coated along the shape of the frame.

Problems often encountered in the process of applying glue are: the amount of glue instability, size head, interface instability and other problems.
