Embodiment 1

[0040] A specific embodiment 1 of a quick fastening device for a circuit board and a copper row of the present invention, this embodiment is as figure 1 As shown, it includes a mounting seat and a fastener anti-rotation structure. The mounting seat includes a bottom support plate 1 and two side plates 2. The support plate is provided with a fixed seat for the anti-rotation piece. The fixed seat for the anti-rotation piece includes a fixed plate 5 and a pressure plate. 6. An anti-rotation piece 7 is arranged on the fixed seat of the anti-rotation piece. The side plates 2 are fixed on both sides of the bottom support plate 1 by three side plate screws 3 respectively, and the fixed plate 5 is installed on the bottom support plate 1 by two fixed plate screws 4 in the area between the two side plates 2 .

[0041] In this embodiment, the inner upper ends of the two side plates 2 are all provided with positioning steps for placing the circuit board 9. The positioning steps constitute...

specific Embodiment 2

[0047] In specific embodiment 2, the difference between a circuit board fastening device in this embodiment and the above-mentioned specific embodiment 1 is only that: Figure 9 and 10 As shown, the mounting seat 21 and the side plate 22 are of an integral structure.

specific Embodiment 3

[0048] In specific embodiment 3, the difference between a circuit board fastening device in this embodiment and the above-mentioned specific embodiment 2 is only that: Figure 11 and 12 As shown, the anti-rotation member fixing seat 35 is an integral structure.

Abstract

The invention provides a circuit board fastening device, and belongs to the field of circuit board assembly fixtures. The circuit board fastening device comprises a fastening piece rotation stop structure for preventing rotation of fastening pieces needing installation, and a mounting base for positioning circuit boards. Header box circuit boards to be assembled and copper bars are firstly combined through bolts and nuts to put on the fastening device; working ends of rotation stop pieces in rotation stop matching are inserted in grooves in bolt countersunk heads through the device; the nuts at the other ends of the bolts are quickly fastened through electric tool sleeves in sequence; and the device is convenient to operate, reduces the labor intensity, and improves the installation efficiency.

Description

technical field [0001] The invention relates to a circuit board assembly tool, in particular to a circuit board fastening device. Background technique [0002] In the photovoltaic DC combiner box, the combiner circuit board (referred to as the circuit board) completes 16 channels of 10A current input, which are aggregated into 160A output. The converging conductive copper foil on the circuit board is 25mm wide, and is fastened to the 25*3mm copper bar by 9 evenly distributed bolts, so that the current flows from the circuit board to the copper bar, and then the copper bar is connected to the electrical circuit of the system. In actual production, the bolt fastening operation between the copper bar and the circuit board is basically done manually by the workers. When installing the bolts, the workers need to tighten the bolt head with one hand and tighten the nut with the other hand. It is difficult to operate with both hands, and it is easy to slip, and the labor intensity i...
