Description

Technical Field

[0001] The present application relates to the field of battery cell testing devices, and more specifically, to a battery cell testing probe. Background Art

[0002] At present, with the development of solar photovoltaic technology, the structure of the cells in the solar panels is becoming more and more sophisticated. Taking crystalline silicon cells as an example, in order to reduce costs and increase efficiency, the electrodes of crystalline silicon cells are getting smaller and smaller, and the electrodes have changed from strips to lines and dots. As the electrodes of crystalline silicon cells are getting smaller and smaller, the contact requirements for testing institutions are getting higher and higher. When testing the performance of crystalline silicon cells, probes are usually used to contact the contacts of crystalline silicon cells so that crystalline silicon cells can be tested.

[0003] During the detection process of some existing probes, the test device usually moves the probes to contact the electrodes of the crystalline silicon cell. At this time, the probes and the electrodes of the crystalline silicon cell squeeze each other to maintain a stable connection, but the probes do not have a buffering effect, which leads to excessive squeezing of the electrodes of the crystalline silicon cell by the probe row in the event of an erroneous operation, which can easily cause damage to the crystalline silicon cell. At the same time, as a consumable material, the probes will cause the probes to be scrapped prematurely, thereby increasing the test cost. For this reason, we propose a cell test probe. Utility Model Content

[0004] In order to solve the above problems, the present application provides a battery cell test probe, which adopts the following technical solution:

[0005] A battery cell test probe comprises a shell, the shell comprising a first half shell and a second half shell arranged on one side of the first half shell, the second half shell is provided with arc grooves distributed in a linear array on the inner wall of the side close to the first half shell, a plurality of arc frames matching the arc grooves are fixedly installed on the side of the first half shell close to the second half shell, connecting columns are slidably installed in the arc frames and arc grooves of the same group, and the bottom ends of the connecting columns are provided with probe bodies, the bottom ends of the probe bodies slide through the shell, and the top ends of the connecting columns are provided with buffer components;

[0007] By adopting the above technical solution, when the device is used, the staff places the probe body in the arc groove and the arc frame in the shell. After the probe body is placed, the staff fits the first half shell with the second half shell, so that the block installed on the side wall of the first half shell is engaged with the groove opened on the side wall of the second half shell, which plays a role in positioning the first half shell and the second half shell.
