Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to an elastic pin row mechanism. Background Art
[0002] Photovoltaic (PV): It is short for solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two operation modes: independent operation and grid-connected operation. At the same time, the solar photovoltaic power generation system can be classified into two types: one is centralized, such as large-scale ground photovoltaic power generation systems in the northwest; the other is distributed (with a boundary of >6MW), such as rooftop photovoltaic power generation systems for industrial and commercial enterprises and residential rooftop photovoltaic power generation systems. Photovoltaic technology has many advantages: for example, it has no mechanical moving parts; except for sunlight, it does not require any other "fuel" and can work under direct and oblique sunlight; moreover, in terms of the selection of the site, it is very convenient and flexible, and rooftops and open spaces in cities can all be utilized. Since 1958, the solar photovoltaic effect has been first applied in the power supply field of space satellites in the form of solar cells. To date, its applications in the power generation field have spread all over the world, from power supply for small automatic parking meters and rooftop solar panels to large-scale solar power generation centers with vast areas.
[0003] Among them, a photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It is composed of thin-film solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Since there are no moving parts, it can operate for a long time without any loss. Simple photovoltaic cells can provide energy for watches and calculators, and more complex photovoltaic systems can provide lighting for houses and supply power to the power grid. Photovoltaic panel assemblies can be made into different shapes, and the assemblies can be connected to generate more electricity. Photovoltaic panel assemblies are used on rooftops and building surfaces, and even as part of windows, skylights or shielding devices. These photovoltaic facilities are usually referred to as photovoltaic systems attached to buildings. To connect the photovoltaic panel assembly to the power grid, a large number of connectors are required. Currently, there is no multi-pin row elastic pin row mechanism with a multi-layer structure specifically for photovoltaic modules. Based on this, this solution provides an elastic pin row mechanism to solve the above-mentioned problems. Summary of the Utility Model

Installation grooves are formed at one end of the two upper fixed brackets facing each other. Sliders are arranged inside the two installation grooves. Elastic brackets are slidably installed at one end of the two sliders facing each other. A first encrypted copper needle row is installed between the two elastic brackets. A pair of slots are symmetrically formed at the top end of the elastic bracket. Spring pins are arranged inside the slots. The upper end of the spring pin abuts against the upper fixed bracket. There are a pair of lower fixed brackets. A second encrypted copper needle row is fixedly installed between the two lower fixed brackets.
[0007] Preferably, both the left and right ends of the first encrypted copper needle row are fixedly connected to the elastic bracket through positioning bolts, and the second encrypted copper needle row is fixedly connected to the upper fixed bracket through a pair of fastening bolts.
[0008] Preferably, the two upper fixed brackets, one first encrypted copper needle row, two sliders, two elastic brackets and four spring pins cooperate with each other to form an upper needle row, and the structures on both sides of the upper needle row are mirror-symmetrically arranged.
[0009] Preferably, both the left and right ends of the second encrypted copper needle row are fixedly connected to the lower fixed bracket through positioning bolts. The second encrypted copper needle row and the two lower fixed brackets form a lower needle row, and the structures on both sides of the lower needle row are mirror-symmetrically arranged.

The upper ends of the spring pins 7 are abutted against the upper fixing bracket 1. There are a pair of lower fixing brackets 2. A second encrypted copper pin row 4 is fixedly installed between the two lower fixing brackets 2. Due to the action of the spring pins 7, the elastic brackets 6 can slide up and down on the surface of the slide blocks 5, so that the impact resistance of the device is better, the battery cells themselves are not easily crushed, thereby reducing the generation of fragments, improving the yield, efficiency and test stability; and this device can be compatible with most battery cells on the market. As long as the number of needle row pairs is increased according to the actual number of main grid lines of the battery cells, the compatibility is good and it is worthy of promotion.

[0021] Specifically, in this embodiment, both the left and right ends of the second encrypted copper pin row 4 are fixedly connected to the lower fixing bracket 2 through positioning bolts. The second encrypted copper pin row 4 and the two lower fixing brackets 2 form a lower pin row, and the structures on both left and right sides of the lower pin row are mirror-symmetrically arranged.
[0022] The working principle of the present utility model is as follows: For the upper pin row of the device, due to the action of the spring pins 7, the elastic brackets 6 can slide up and down on the surface of the sliders 5.
