Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Embodiment 1, as shown in fig. 1, the present utility model provides the technical scheme: the novel photovoltaic module junction box comprises a negative electrode junction box 1, a middle junction box 2, a positive electrode junction box 3 and a photovoltaic module, wherein the negative electrode junction box 1, the middle junction box 2 and the positive electrode junction box 3 are all installed on a backboard of the photovoltaic module and are connected with an internal bus-bar and a battery piece of the photovoltaic module, and the positive electrode junction box 3 on the photovoltaic module is connected with the negative electrode junction box 1 on the photovoltaic module;
the positive terminal box 3 is connected with a cable 5, the other end of the cable 5 is connected with a positive connector 4, and the positive connector 4 is connected with the negative terminal box 1 on the next group of photovoltaic modules in a butt-inserting mode.
However, the negative electrode terminal box 1 is not connected with the cable 5, and the negative electrode connector 6 is not connected with the cable 5 as shown in fig. 2, but is connected in series with the intermediate terminal box 2, so that in the production process, the extra cable and the negative electrode connector 6 do not need to be reproduced, and corresponding assembly operation is not needed, thereby contributing to the improvement of the efficiency of automatic production.
The length of the cable 5 led out from the positive terminal box 3 is reduced by 40cm, so that the overlong cable 5 is not required to be bundled, and various products are not derived, and the automatic production is difficult.
As described above, when a plurality of junction boxes are connected, only the positive electrode connector 4 on the positive electrode junction box 3 on the former module and the negative electrode junction box 1 on the latter module are required to be plugged, one negative electrode connector 6 and the cable 5 on the negative electrode junction box 1 are reduced, and the effect of reducing line loss and cost is remarkable, but as shown in fig. 3, when a plurality of junction boxes are connected in the application engineering, not only the cables 5 are required to be connected to the respective positive electrode junction boxes 3 and negative electrode junction boxes 1, but also the positive electrode connector 4 and the negative electrode connector 6 are required to be butted in the air, the connection is troublesome, and the hidden trouble of excessive lines is also increased.
In embodiment 2, unlike embodiment 1, in this embodiment, the positive electrode connector 4 and the cable 5 thereon are omitted, and the negative electrode connector 6 and the cable 5 thereon are left, and then, at the time of connection, the negative electrode connector 6 on the negative electrode terminal box 1 on the former module is plugged with the positive electrode terminal box 3 on the latter module, thereby connecting into a module string. Such an actual application effect is equivalent to that in embodiment 1.
