Description

Technical Field

[0001] This invention relates to the field of electronic testing technology, and more specifically to a concentric battery detection probe. Background Technology

[0002] Before stringing solar cells, all cells must be inspected and classified. Quickly and accurately testing the electrical performance of solar cells is a crucial step that not only affects the final performance of the solar module but also directly impacts the testing efficiency.

[0003] Probes are used in electronic testing to test connected electronic components. Manufacturers typically use probes to test the electrical performance of battery cells. Currently, the positive and negative terminals of existing batteries are generally located at the head and tail of the battery, respectively, so the positive and negative probes of the charge / discharge machine are distributed at the top and bottom of the machine. However, for new batteries with positive and negative terminals led out from the same end, battery probes are generally used to test the positive and negative terminals of the battery sequentially. This causes problems such as inconvenience and long testing time. The original probe structure can no longer meet the needs of charging and discharging new batteries.

[0004] In view of this, it is indeed necessary to provide a technical solution to the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a concentric battery detection probe that solves the problem of inconvenience in testing novel batteries caused by the aforementioned probe structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concentric battery detection probe, comprising:

[0008] The mounting base has an inner cavity;

[0009] A first current needle is disposed in the inner cavity, and a first through hole is opened on the first current needle;

[0010] The first voltage needle is insulated and disposed in the first through hole, with one end of the first voltage needle passing through the mounting base;

[0011] The second current needle is coaxially arranged with the first current needle, and one end of the second current needle passes through the mounting base, while the other end passes through the first current needle;

[0012] The second voltage needle is insulated on the axis of the second current needle, and the second voltage needle passes through the second current needle along the axis.

[0013] As an improvement to the concentric battery detection probe, a guide is provided between the first current needle and the second current needle, and the guide is sleeved on the outside of the second current needle.

[0014] As an improvement to the concentric battery detection probe, it further includes a first spring, a second spring, a third spring, and a fourth spring. The first spring is disposed between the first current needle and the mounting base, the second spring is disposed between the first voltage needle and the mounting base, the third spring is disposed between the guide and the second current needle, and the fifth spring is insulated between the second current needle and the second voltage needle.

[0015] As an improvement to the concentric battery detection probe, the guide includes an upper guide sleeve and a lower guide sleeve, the lower guide sleeve slides within the upper guide sleeve, the upper guide sleeve is connected to one end of the third spring, and a fifth spring is provided between the lower guide sleeve and the upper guide sleeve.

[0016] As an improvement to the concentric battery detection probe, a copper post is provided on the first current needle, the copper post passes through the mounting base, and a first spring is wound around the copper post.

[0017] As an improvement to the concentric battery detection probe, multiple copper pillars are provided, and a first connecting plate is provided between the outer ends of the copper pillars.

[0018] As an improvement to the concentric battery detection probe, the bottoms of the first current needle and the second current needle are at the same horizontal height, and the first voltage needle protrudes downward along the first through hole and is at the same horizontal height as the second voltage needle.

[0019] As an improvement to the concentric battery detection probe, the bottom of the first current needle, the first voltage needle, the second current needle, and the second voltage needle are all provided with several protrusions.

[0021] As an improvement to the concentric battery detection probe, a recessed platform is provided on the outside of the second contact portion, and the recessed platform is engaged with the guide member.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1) The present invention uses a first current needle and a first voltage needle to contact one of the poles of the novel battery, and a second current needle and a second voltage needle to contact the other pole of the novel battery, so as to test the positive and negative poles of the novel battery at the same time, thereby making it more convenient to adapt to the charging and discharging needs of the novel battery. The first current needle, the first voltage needle, the second current needle and the second voltage needle are coaxial, so that the first current needle and the second current needle can be guaranteed to be in the correct charging and discharging position.

[0024] 2) The present invention can simultaneously ensure that the first current needle and the second current needle are subjected to equal downward pressure through the mounting base, thereby effectively reducing the error of the test data and greatly improving the test effect.

[0025] 3) During the performance testing of the new battery, the upper and lower guide sleeves can better guide the second current needle, further ensuring that the second current needle is in the correct charging and discharging position, and completely separating the first current needle from the second current needle.

Detailed Implementation

[0031] To make the technical solution and advantages of the present invention clearer, the present invention and its beneficial effects will be described in further detail below with reference to specific embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a concentric battery detection probe includes a mounting base 1, a first current needle 2, a first voltage needle 3, a second current needle 6, and a second voltage needle 7. The mounting base 1 has an inner cavity, and the first current needle 2 is disposed in the inner cavity. The first current needle 2 has a first through hole, and the first voltage needle 3 is insulatedly disposed in the first through hole. One end of the first voltage needle 3 passes through the mounting base 1 and the second current needle 6, and is coaxially disposed with the first current needle 2. One end of the second current needle 6 passes through the mounting base 1, and the other end passes through the first current needle 2 and the second voltage needle 7, and is insulatedly disposed on the axis of the second current needle 6. The second voltage needle 7 passes through the second current needle 6 along the axis.

[0035] Specifically, the first current needle 2 is slidably disposed in the inner cavity and fits against the inner cavity. The first current needle 2 is annular, and there are two first through holes symmetrically disposed on the first current needle 2. The first through holes are vertical, and each first through hole is provided with a first insulating sleeve 15. The first voltage needle 3 slides in the insulating sleeve. Each first voltage needle 3 is provided with two first insulating blocks 16, which are distributed vertically on the first voltage needle 3. The first insulating blocks 16 are cylindrical with a larger diameter at the top than at the bottom, and the diameter of the upper end is larger than the diameter of the first through hole. The upper ends of the two first insulating blocks 16 are respectively located on the upper surface of the first current needle 2 and the mounting base 1. The second current needle 6 is also annular. The second current needle 6 is provided with a second insulating sleeve 17. The second voltage needle 7 slides in the second insulating sleeve 17. The second voltage needle 7 is coaxial with the second current needle 6. The second voltage needle 7 is provided with two second insulating blocks 18 of different shapes. The two second insulating blocks 18 are respectively distributed at the upper and lower ends of the second voltage needle 7 to separate the second current needle 6 and the second voltage needle 7. Both second insulating blocks 18 are slidably connected to the inner wall of the second current needle 6. The first current needle 2, the first voltage needle 3, the second current needle 6 and the second voltage needle 7 are coaxial. The second voltage needle 7 is a plate-type voltage needle, which increases the contact area between the second voltage needle 7 and the new battery and improves the test effect.

[0036] The present invention uses a first current needle 2 and a first voltage needle 3 to contact one of the electrodes of the novel battery, and a second current needle 6 and a second voltage needle 7 to contact the other electrode of the novel battery. At the same time, the positive and negative electrodes of the novel battery are charged, discharged or sampled, thus making it more convenient to adapt to the charging and discharging needs of the novel battery. The first current needle 2, the first voltage needle 3, the second current needle 6 and the second voltage needle 7 are coaxial, so that the first current needle 2 and the second current needle 6 can be kept in the correct charging and discharging position.

[0037] More preferably, a guide 10 is provided between the first current needle 2 and the second current needle 6, and the guide 10 is sleeved on the outside of the second current needle 6. Specifically, the guide 10 is an insulating guide 10. When the first current needle 2, the first voltage needle 3, the second current needle 6, and the second voltage needle 7 charge, discharge, or sample the novel battery, the presence of the guide 10 ensures that the second current needle 6 will not be eccentric, further ensuring that the second current needle 6 is in the correct charging position, resulting in better testing performance.

[0038] More preferably, it also includes a first spring 4, a second spring 5, a third spring 8, and a fourth spring 9. The first spring 4 is disposed between the first current needle 2 and the mounting base 1, the second spring 5 is disposed between the first voltage needle 3 and the mounting base 1, the third spring 8 is disposed between the guide member 10 and the second current needle 6, and the fourth spring 9 is insulated between the second current needle 6 and the second voltage needle 7. Specifically, the mounting base 1 is provided with multiple mounting holes. The probe is mounted on the testing equipment through the mounting holes. When it is necessary to charge / discharge or sample the new battery, the probe is moved above the terminals of the new battery. The testing equipment moves the entire probe downward through the mounting base 1 until the first voltage needle 3 and the second voltage needle 7 simultaneously contact the two terminals of the new battery. Then, the mounting base 1 moves the first current needle 2 and the second current needle 6 further downward, compressing the second spring 5 and the fourth spring 9. Then, the first current needle 2 and the second current needle 6 also contact the two terminals of the new battery. The mounting base 1 continues to move downward for a while and then stops. The first spring 4 and the third spring 8 are compressed, so that the first current needle 2, the first voltage needle 6, the second voltage needle 7, and the second voltage needle 8 simultaneously contact the two terminals of the new battery. Voltage needle 3, second current needle 6, and second voltage needle 7 are all in close contact with the two poles of the new battery. Subsequently, the testing equipment uploads the test data of the new battery. After the test is completed, the testing equipment moves the mounting base 1 upward, and the first current needle 2, first voltage needle 3, second current needle 6, and second voltage needle 7 all move upward and reset. The first spring 4, second spring 5, third spring, and fourth spring 9 are all reset due to their elasticity. This achieves the purpose of simultaneously testing the two poles of the new battery at the same end, and also has the effect of automatic reset after the test. Furthermore, the mounting base 1 can simultaneously make the first current needle and the second current needle 6 bear equal downward force, thereby effectively reducing the error of the test data and greatly improving the test effect.

[0039] More preferably, the guide member 10 includes an upper guide sleeve 1001 and a lower guide sleeve 1002, the lower guide sleeve 1002 slides inside the upper guide sleeve 1001, the upper guide sleeve 1001 is connected to one end of the third spring 8, and a fifth spring 1003 is provided between the lower guide sleeve 1002 and the upper guide sleeve 1001. Specifically, the fifth spring 1003 is wound around the lower guide sleeve 1002. The upper guide sleeve 1001 has a groove that matches the upper end of the lower guide sleeve 1002. The lower guide sleeve 1002 slides in the groove. When the second voltage needle 7 contacts the electrode of the new battery, the lower end of the lower guide sleeve 1002 also contacts the electrode of the new battery. Then the lower guide sleeve 1002 moves upward together with the second voltage needle 7, and the fifth spring 1003 is compressed, so that the lower guide sleeve 1002 does not affect the testing of the new battery. At the same time, it ensures that when testing the new battery, the upper guide sleeve 1001 and the lower guide sleeve 1002 can better guide the second current needle 6 and completely separate the first current needle 2 from the second current needle 6.

[0040] More preferably, a copper post 11 is provided on the first current needle 2, the copper post 11 passes through the mounting base 1, and the first spring 4 is wound around the copper post 11. Specifically, four copper posts 11 are provided, the copper posts 11 are threadedly connected to the first current needle 2, and a nut is provided at the upper end of the copper post 11 to prevent the copper post 11 from wobbling downward.

[0041] More preferably, multiple copper pillars 11 are provided, and a first connecting plate 12 is provided between the outer ends of the copper pillars 11. Specifically, the first connecting plate 12 can be used as the output end of the first current needle 2 and electrically connected to the test equipment. The upper end of the second current needle 6 is fixedly connected to the second connecting plate 13 by a nut. The second connecting plate 13 serves as the output end of the second current needle 6 and is electrically connected to the test equipment.

[0042] More preferably, the bottoms of the first current needle 2 and the second current needle 6 are at the same horizontal height, and the first voltage needle 3 protrudes downward along the first through hole and is at the same horizontal height as the second voltage needle 7.

[0043] More preferably, the bottom of the first current needle 2, the first voltage needle 3, the second current needle 6, and the second voltage needle 7 are all provided with a plurality of protrusions 14, which are used to provide electrical connection when the battery is subjected to electrical performance testing.

[0044] More preferably, the second current needle 6 includes a second base 601 and a second contact portion 602, with the second contact portion 602 detachably connected to the lower end of the second base 601. Specifically, the second contact portion 602 is threadedly connected to the second base 601. The first current needle 2 includes a first base 201 and a first contact portion 202, with the second contact portion 602 threadedly connected to the lower end of the second base 601. The second contact portion 602 and the first contact portion 202 are detachable, allowing for direct disassembly and replacement of either the first current needle 2 or the second current needle 6 when damaged, without disassembling the entire module, thus saving manpower and resources.

[0045] More preferably, a recessed platform is provided on the outside of the second contact portion 602, and the recessed platform engages with the guide member 10. Specifically, the lower guide sleeve 1002 engages with the recessed platform to prevent the lower guide sleeve 1002 from protruding downwards, so that even if the lower guide sleeve 1002 moves upwards simultaneously with the second voltage needle 7, the lower guide sleeve 1002 remains in contact with the second current needle 6 due to the recessed platform, thus guiding it.

Therefore, the present invention is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
