Problems solved by technology

This spring clamping fixing method has the problem of unreliable fixing, and because the pressure is not large enough, when the bus bar is deformed, the bus bar and the terminal body have problems such as small contact resistance and easy heating. Seriously affects the safety performance of the junction box during use

Embodiment Construction

[0022] Such as Figure 1 to Figure 5 As shown in the solar cell panel bus bar fixing mechanism, the bus bar fixing mechanism presses and fixes the bus bar by buckling, and the buckling part of the bus bar bends during the buckling process, forming a knot shape, difficult to fall off.

[0023] Including positioning part and pressing part.

[0024] The positioning part includes a substrate 1 and busbars 2 mounted on the substrate, and there are four busbars in the figure. The base plate 1 is an insulating board and serves as a mounting platform for other components. The bus bar 2 is a box-shaped body upside down on the substrate 1, which is a sheet metal part. The front part of the bus bar 2 is a cable installation part 21, which is used to connect with the cables in the power grid; Different bus bars are connected; there is a rectangular opening 3 on the upper surface of the rear part, which is used to locate the bus bar 4, and the front and rear edges of the rectangular ope...

Abstract

The invention discloses a solar cell panel busbar fixing mechanism, and relates to improvement on a connection structure in a solar junction box. The solar cell panel busbar fixing mechanism comprises a positioning part and a laminating part, wherein the positioning part comprises a substrate and a busbar; a rectangular opening is formed on the rear of the busbar; the laminating part comprises an insulating substrate; a trapezoidal protrusion is formed on the inner side of the substrate; and the middle of a C-shaped metal snap spring is fixed on the trapezoidal protrusion of the substrate through a screw. The laminating part laminates and fixes the busbar on the positioning part in a fastening mode. The solar cell panel busbar fixing mechanism has the characteristics of reliable fixation and convenience of operation, and also improves electric properties of the junction box.

Description

technical field [0001] The invention relates to a partial structure in a junction box of a solar battery panel, in particular to a fixing mechanism for a bus bar of a solar battery panel. Background technique [0002] The solar junction box is an important component in the field of solar power generation. The main function of the junction box is to connect the bus bar with the external circuit. It has high electrical requirements, requires strong holding force and pressing force, and good electrical conductivity. And anti-arc performance to ensure the safety and reliability of the bus bar connection. [0003] The bus bar fixing mechanism in the existing junction box generally fixes the bus bar through the clip spring. Since it is completely fixed by the elastic force of the clip spring, the fixing effect is poor, and in order to ensure the force of the clip spring, the clip part is generally The gap design is very small, and the installation operation is very inconvenient. ...
