Embodiment Construction

[0025] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following will be described in detail in conjunction with embodiments and accompanying drawings.

[0026] Such as figure 1 As shown, a plurality of sheet-shaped solar cell soldering pads 2 are laid on the front surface of the substrate 1, and both ends of the solar cell string 11 pasted on the front surface of the substrate are connected to the solar cell soldering pads 2 respectively. In order to facilitate welding, the solar cell welding pad 2 should be arranged on the edge of the base plate 1. The solar cell welding plate 2 is made of a metal material that is easy to weld, has low resistance, is soft, and has good toughness, preferably silver, copper or a valveable alloy, and the thickness does not exceed 0.5 mm.

[0027] Such as figure 2 As shown, a sheet-like cable 3 is laid on the back of the substrate 1. The cable 3 is composed of a...

Abstract

The invention discloses a connecting method for solar cell array front and back face circuits. The method comprises the steps of (1), laying a sheet-shaped solar cell welding disc on the front face of a substrate, and laying a sheet-shaped cable on the back face of the substrate; (2) welding the two ends of a metal sheet to the solar cell welding disc on the front face of the substrate and the cable on the back face of the substrate respectively. Due to the facts that the solar cell welding disc is in a sheet shape, the cable is in a sheet shape, and the metal sheet is adopted to be connected with the cable and the solar cell welding disc, the connecting thickness is small due to the connecting mode, and the drawing size of a solar cell array is not affected.

Description

[0001] Technical field [0002] The invention relates to battery technology, in particular to a method for connecting the front and back circuits of a solar cell array. Background technique [0003] Most of the spacecraft are powered by solar cell arrays, and the electrical energy from the solar cell strings on the solar cell arrays is transmitted to the spacecraft through cables for use by the spacecraft. The cable of the traditional solar cell array uses multiple wires. The cable is bundled into a bundle and fixed on the back of the substrate. One end of the cable passes through the hole on the substrate to connect to the solar cell string on the front of the substrate, and the other end is driven by the solar cell array. Institutions are connected. The connection method of the front and back circuits of the solar cell array has the problem of large cable thickness, which affects the volume of the solar cell array. In addition, the multi-stranded cable can only be soldered when...
