But it has the following defects: 1. The fixing method of the power management module in the cavity formed by the box body and the lid is relatively complicated, and the power management module is easy to shake
2. The connection between the cable and the power management module is relatively loose, which is easy to cause an open circuit
3. The sealing effect of the box body and the box cover is poor, and the box body and the box cover are easy to disengage
4. Poor heat dissipation

Embodiment Construction
[0021] Examples, see Figure 1 to Figure 4 As shown: the junction box of an intelligent management module for photovoltaics, including a box body 11 and a box cover 12 snapped together, and the two ends of the box body 11 and / or the box cover 12 are provided with fixing ferrules 13 for fixing the cable 100 . That is, the fixing ferrule 13 can be located at both ends of the box body 11 , or at both ends of the box cover 12 , or have half on the box body 11 and the box cover 12 . Meanwhile, a power management module 20 connected to a cable 100 is disposed in the cavity formed by the box body 11 and the box cover 12 , and the power management module 20 includes electrodes 21 and a power management module carrier 22 . More specifically, an adaptive spring 111 is disposed inside the box body 11 , and the adaptive spring 111 is matched with the power management module 20 . Of course, the self-adaptive springs 111 can be arranged in multiple rows. In this way, the fixing of the po...

The invention discloses a photovoltaic intelligent management module junction box, comprising a box body and a box cover which are buckled together, wherein fixing clamping sleeves used for fixing wire cables are arranged at the two ends of the box body and / or the box cover, a power management module connected with the wire cables is also arranged in a cavity formed by the box body and the box cover, the power management module comprises electrodes and a power management module carrier, a self-adaptive spring is arranged in the box body, and the self-adaptive spring is matched with the power management module. After optimization, the interior of the fixing clamping sleeves forms a structure shaped like a Chinese character 'wang'; a foam seal ring is arranged at the edge of the box cover; and slot-type heat dissipation channels are arranged on the outer surface of the box body and positioned at the two sides of the longitudinal center line of the box body. The photovoltaic intelligent management module junction box has the advantages that the fixation mode of the power management module in the cavity formed by the box body and the box cover is simpler, and the power management module cannot swing easily.
Description
technical field [0001] The invention relates to the technical field of photovoltaic products, in particular to an intelligent management module junction box for photovoltaics. Background technique [0002] With the rapid development of photovoltaic industry, photovoltaic junction boxes are widely used. Among them, there is a photovoltaic junction box that includes a box body and a box cover that are snapped together, and two ends of the box body and / or the box cover are provided with fixing ferrules for fixing cables. At the same time, the cavity formed by the box body and the box cover is provided with a connection and cable power management module, and the power management module includes electrodes and a power management module carrier. Such a photovoltaic junction box has a simple structure and is commonly used. However, it has the following defects: 1. The fixing method of the power management module in the cavity formed by the box body and the box cover is relatively...
