Embodiment Construction

[0021] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] Such as Figure 1 to Figure 2 Shown is a common glue-filled junction box in the prior art. The front of the junction box has a bus bar connection window 12. After the worker fixes the junction box on the photovoltaic cell module backplane or glass 3, the bus bar Operation in the wiring window 12, after the terminal 4 is connected with the bus bar 7, the glue filling type junction box of filling the bus bar wiring window 12 and adding a plastic upper cover 13 after connecting the terminal 4 and the bus bar 7. In order to ensure the sealing of the junction box, a sealing strip 14 is also assembled in the plastic upper cover 13 ....

Abstract

The invention relates to the field of photovoltaic technologies and discloses a photovoltaic cell module terminal box of a wiring window free of bus bars on the surface. The photovoltaic cell module terminal box of the wiring window free of the bus bars on the surface comprises a plastic box body for an output wire cable to be connected in a sealed mode, wherein an opening is formed at the bonding position of the back side of the plastic box body and a photovoltaic cell module back board or glass, the front side and the lateral side of the plastic box body are airtight and free of windows, wiring terminals with the same number as the bus bars led out of photovoltaic cell module back board or the glass are arranged in the plastic box body, a bypass diode is connected between adjacent wiring terminals, the wiring terminals at two ends are respectively connected with positive and negative poles of the output wire cable and respectively provided with heat-dissipation conductive metal pieces, and diodes are arranged on the heat-dissipation conductive metal pieces. The photovoltaic cell module terminal box is simple in structure, the surface of the plastic box body is airtight and free of windows, the heat dissipation effect is ideal, the electricity generation attenuation loss is reduced, waterproof reliability is good, installation operation is convenient, and the manufacturing and follow-up installation and usage cost of the terminal box is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaics, in particular to a junction box for a photovoltaic battery module without a bus bar junction window on the surface. Background technique [0002] In the field of photovoltaic technology, we generally refer to the bonding surface of the photovoltaic cell module junction box and the photovoltaic cell module backplane or glass as the back of the junction box, and the projected symmetrical surface on the back is called the front of the junction box, and other peripheral surfaces can be Called the sides, the front and sides may be collectively referred to as surfaces. [0003] There are generally two ways to connect the terminal box of the photovoltaic cell module junction box to the busbar of the solar panel: one is to attach the back of the junction box to the backplane or glass of the photovoltaic cell module, and connect the busbar from the window on the front of the junction box. Solder co...
