JUNCTION BOX FOR SOLAR BATTERY MODULE

摘要

A junction box for a solar battery module comprises a box cover (10), a box body (3) and at least two control circuits (2) placed inside the box body (3), and the control circuits are not connected electrically with each other directly. The control circuit (2) includes a diode. Each control circuit (2) is connected in parallel with at least a by-pass which is formed by connection of solar battery module units in series in the solar battery module (9). A heat dissipating part (4) is provided on the box cover (10) and a cable connecting piece is provided on the box body (3). The diode is connected with the heat dissipating part (4) by a connecting part which is made of insulating material with good thermal conductivity. The junction box can save cable connecting wires, improve system installation efficiency, have a good heat dissipating effect and reduce the quantity of the junction box used in the solar battery module which has many by-passes.
