Problems solved by technology

[0003] 1. High production cost; the traditional test needle is composed of three parts: probe cover, spring and probe head. The assembly process of these three parts is relatively complicated and requires manual processing and combination, which has certain requirements for the accuracy of the product. cost of production
[0004] 2. It is easy to be damaged; the inside of the traditional test needle is a spring core. Since the spring is arranged between the probe head and the probe cover, it is easy to be elastically deformed after a long period of pressing down, resulting in a gap between the probe head and the probe cover. Once the jamming phenomenon occurs, it will crush the busbar on the cell and damage the cell, and the probe must be replaced
[0005] 3. The service life is short; since the probe cover and the probe head are slidingly connected, after long-term use, wear will occur between the inner wall of the probe cover and the outer wall of the probe head, which will cau

Embodiment 1

[0022] The solar cell sheet spring test probe of the present invention is provided with a linear connector 1, a spring part 2 and a contact 3 sequentially from top to bottom, and the linear connector 1, spring part 2 and contact 3 are integrated Structure; the spring part 2 is a quasi-S-shaped spring, and the contact 3 is linear; a buffer ring 4 is respectively provided inside the two bent ends of the quasi-S-shaped spring. The linear connector 1, the spring part 2 and the contact 3 of the probe described in this embodiment are all cylindrical with the same diameter, and the diameter thereof is 0.5 mm. The probes described in this embodiment are made of phosphor bronze probes or aluminum cupronickel wires. The phosphor bronze probes or aluminum cupronickel wire probes have good compression resistance and prevent fatigue points of materials. The S-shaped spring of the present invention replaces the original spring structure, and plays a good buffering role between the connector...

Embodiment 2

[0025] This embodiment is basically the same as Embodiment 1, except that the connector 1 described in this embodiment is a connector 1 in the shape of "?", and the probe can be hooked on the test device by using the connector 1 of this shape. , and fixed, the hook structure described in this embodiment has better convenience in installation and fixation than the linear structure described in embodiment 1.

Embodiment 3

[0027] This embodiment is basically the same as Embodiment 1 or 2, the difference is that there are multiple sets of spring parts 2 in this embodiment, and multiple sets of spring parts 2 have better cushioning performance, stronger elasticity, and can protect solar energy more favorably. battery to prevent it from being crushed.

Abstract

The invention discloses a solar cell spring testing probe and relates to matching members for solar cell testing, in particular to a probe member for testing electrical performance of solar cell. The solar cell spring testing probe sequentially comprises a connecting head, a spring portion and a contact from top to bottom, the connecting head, the spring portion and the contact are of an integral structure, the spring portion is a S-like spring, and the contact is linear. The connecting head, the spring portion and the contact are designed to be of the integral structure, the connecting head is fixed inside a testing device, and the spring portion and the contact are compressed through the testing device to realize testing. Due to the integral structure, production cost is lowered, jamming between the spring and the contact is reduced, the solar cell spring testing probe is less prone to being damaged and high in practicability, and testing resistance and light shading area are reduced.

Description

technical field [0001] The invention relates to a solar battery sheet test fitting, in particular to a probe piece for testing the electrical properties of a solar battery sheet. Background technique [0002] With the society's increasing demand for energy and the country's emphasis on and support for green energy, the solar cell industry has developed vigorously. During the production process of solar cells, various electrical properties of the cells must be tested, such as In the IV test of photovoltaic cells, it is necessary to collect the current and voltage information generated by the cells under certain lighting conditions; while in the detection of electroluminescent defects, it is necessary to test the cells with power. At present, the collection or power-on of the electric signal of the battery is to use the test needle to contact the main grid line on the battery, and the existing test probe is mostly composed of three parts: the probe cover, the spring, and the p...
