Metallic support be set to middle metallic support, after the diode of described side metallic support is arranged on its corresponding busbar access aperture
Side, the diode of middle metallic support are arranged on the front side of its corresponding busbar access aperture.
Preferably, diode includes the side diode being arranged on the metallic support of side, it is arranged on middle metallic support
Middle diode, side diode, the distribution triangular in shape of middle diode, and middle diode are located at back box front portion.
Preferably, the length of side metallic support fore-and-aft direction is less than the length of middle metallic support fore-and-aft direction, side metal
The surface area of support is less than the surface area of middle metallic support.
Preferably, side diode is mutually inclined into angle setting.
Preferably, the rear end of back box is provided with two cable interfaces, described cable interface is mutually inclined into angle and set
Put, the angle that described cable interface is formed slopely is mutually inclined the angle to be formed with side diode and is oppositely arranged.
For photovoltaic junction box, the diode heating most serious positioned at centre.Diode includes being arranged on side metal
Side diode on support, the middle diode being arranged on middle metallic support, reflux condition on diverse location metallic support is accessed
The relative position of hole and diode is adjusted, and the middle diode on centrally located middle metallic support is arranged on busbar
The front side of access aperture, the side diode on the metallic support of side are arranged on the rear side of its corresponding reflux condition access aperture, then middle diode
It is arranged far from cell piece position, can effectively prevent hot spot effect.
By diode distribution triangular in shape, then it ensure that middle metal support surface area is more than side metal support surface face
It is long-pending, diode radiating in auxiliary, reduce heating temp during work.
