SMART JUNCTION BOX FOR SOLAR CELL MODULE
First Claim
1. A smart junction box for a solar cell module, comprising:
- bus bars for transmitting electricity flowing from ribbon cables;
pressing units for selectively fastening and separating the ribbon cables located on contact portions of the bus bars;
diodes each configured to have a hexahedral shape, provided with thermally conductive metal on one surface thereof, disposed so as to be in contact with a corresponding heat sink plate in a surface contact manner, and provided with two terminals so as to be disposed in contact with a corresponding bus bar;
heat sink plates disposed in contact with the bus bars, and configured to emit heat conducted through the bus bars and the metal of the diodes to an outside;
fastening means for fastening the bus bars, the diodes and the heat sink plates to each other; and
external cables for providing electricity transmitted from the bus bars to the outside,

Abstract
The present invention relates to a smart junction box for a solar cell module, and provides a smart junction box for a solar cell module which enables an operator to easily connect and separate ribbon cables using the operation of the levers of pressing units, thereby being able to improve the contact stability of ribbon cables, and which has a heat sink structure, thereby effectively emitting the heat generated by the ribbon cables and the diodes to the outside. For this purpose, the smart junction box for a solar cell module of the present invention includes bus bars for transmitting electricity flowing from ribbon cables; and pressing units for selectively fastening and separating the ribbon cables located on contact portions of the bus bars depending on whether both ends of the lever projected by the manipulation of an operator are inserted into recesses formed in a body.
