[0001] This utility model relates to the technical field of lithium battery formation and capacity testing equipment, specifically to a power cabinet spring probe type test fixture. Background Technology

[0002] Lithium-ion battery formation and capacity testing equipment performs tests based on current and voltage lines to complete the formation and capacity testing of the battery. Currently, the industry standard for testing lithium-ion battery formation and capacity power cabinets is to connect the device under test by wiring, screwing, or plugging in terminal blocks. However, wiring and screwing are time-consuming and prone to incorrect connections; while terminal blocks improve time efficiency, they can lead to poor contact after repeated use.

[0003] Meanwhile, the composition and compatibility test requires multiple disassembly and assembly tests. The frequent disassembly, assembly, wiring, and screw tightening during the test process will further lead to problems such as long time consumption and low work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a power cabinet spring probe type test fixture, which adopts the following technical solution:

[0005] A power cabinet spring probe type test fixture includes a chassis, and a handle fixing plate and a fixing block are fixedly installed on the upper surface of one end of the chassis;

[0006] A handle is mounted on the handle fixing plate. The handle is connected to a connecting arm. One end of the handle is connected to the connecting arm, and the other end of the connecting arm is connected to a push-pull rod. One end of the push-pull rod is connected to the connecting arm, and the other end of the push-pull rod is connected to a probe clamp. A spring probe is installed on the probe clamp.

[0007] There are two fixing blocks, symmetrically arranged on both sides of the fixing plate. Each block is slidably connected to a fixing rod. One end of the fixing rod passes through the fixing block, and the other end of the fixing rod is fixedly connected to the probe clamp.

[0008] A movable limiting block is also installed on the upper surface of the other end of the chassis. The movable limiting block can move back and forth between one end of the chassis and the probe fixture.

[0009] Furthermore, the handle has an "L" shaped structure, including an upper push-pull part and a lower connecting part. One end of the connecting part is connected to the handle fixing plate through a pin structure, and the other end is connected to the connecting arm through a pin structure.

[0010] Furthermore, the handle fixing plate includes a base and a support base. The base is fixedly mounted on the chassis by bolts, and the support base is fixedly mounted on the base.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-3 A power cabinet spring probe type test fixture includes a chassis 1. A handle fixing plate 2 and a fixing block 3 are fixedly installed on the upper surface of one end of the chassis 1. There are two fixing blocks 3, which are symmetrically arranged on both sides of the fixing plate 2, so as to better play the role of stable positioning.

[0025] The handle fixing plate 2 includes a base 26 and a support 27. The base 26 is fixedly installed on the chassis 1 by bolts, and the support 27 is fixedly installed on the base 26. One end of the support 27 is provided with a connecting seat 28, and the other end is provided with a limit sleeve 29.

[0026] A handle 21 is mounted on the handle mounting plate 2. A connecting arm 22 is connected to the handle 21. One end of the handle 21 is connected to the connecting arm 22, and the other end of the connecting arm 22 is connected to a push-pull rod 23. One end of the push-pull rod 23 is connected to the connecting arm 22, and the other end is connected to a probe clamp 4. A spring probe 5 is mounted on the probe clamp 4. The spring probe 5 is used to insert and connect to the power supply cabinet 8 under test. Specifically, the spring probe 5, also known as a probe or pin, is a commonly used precision connection device in the testing field. In actual use, different spring probes can be selected according to actual needs.

[0027] Meanwhile, each of the fixing blocks 3 is connected to a fixing rod 31, and each of the fixing blocks 3 is provided with a sliding hole 32. One end of the fixing rod 31 passes through the sliding hole 32 on the fixing block 3 and is slidably connected to the fixing block 3. The other end of the fixing rod 31 is fixedly connected to the probe clamp 4. The length of the fixing rod 31 is longer than that of the push-pull rod 23 to prevent the fixing rod 31 from sliding out of the sliding hole 32 when the probe clamp 4 moves.

[0028] In addition, two movable limiting blocks 6 are installed on the upper surface of the other end of the chassis 1 to better achieve the limiting function. The movable limiting blocks 6 can move linearly back and forth between the end of the chassis 1 on which they are installed and the probe clamp 4. Specifically, the movable limiting blocks 6 have a screw hole in the middle, and the chassis 1 has a corresponding straight slot hole to facilitate the movement of the movable limiting blocks 6. The movable limiting blocks 6 are tightened and fixed by bolts passing through the screw hole and the straight slot hole on the chassis 1.

[0029] With the above setup, when testing is required, the operator can place the power supply cabinet 8 to be tested in the middle of the chassis 1, between the probe clamp 4 and the movable limiting block 6. Then, the movable limiting block 6 is moved through the straight slot to position the power supply cabinet under test. The bolts on the movable limiting block 6 are then tightened to secure it. Next, the handle 21 is pushed, which in turn pushes the connecting arm 22. The connecting arm 22 further pushes the push-pull rod 23, which in turn pushes the probe clamp 4. The probe clamp 4 then connects the spring probe 5 to the power supply cabinet 8 under test. After testing is complete, the operator simply pulls the handle 21 in the opposite direction to separate the spring probe 5 from the power supply cabinet 8. This greatly simplifies the entire testing process and improves work efficiency.

[0030] In one specific implementation, the handle 21 has an "L"-shaped structure, including an upper push-pull portion 24 and a lower connecting portion 25. One end of the connecting portion 25 is connected to the connecting seat 28 via a pin structure, and the other end is connected to the connecting arm 22 via a pin structure. Simultaneously, one end of the push-pull rod 23 passes through the limiting sleeve 29 and is connected to the other end of the connecting arm 22 via a pin structure. Combined with... Figure 2 As can be seen, this is the state when the spring probe 5 is connected to the power cabinet 8 under test. The operator only needs to pull the push-pull part 24 of the handle 21. The handle 21 rotates backward around the connection point between the connecting part 25 and the connecting seat 28, thereby causing the other end of the connecting part 25 to tilt upward, which in turn causes the connecting arm 22 to tilt upward and move backward, thus pulling the push-pull rod 23. Due to the presence of the limiting sleeve 29, the push-pull rod 23 can only move horizontally back and forth, so the spring probe 5 can also only move horizontally back and forth, thus ensuring smooth connection and disconnection each time. Of course, when it is necessary to connect the power cabinet 8 under test for testing, the operator only needs to push the push-pull part 24 of the handle 21, and the other related parts will move in the opposite direction to complete the connection.

[0031] In one specific implementation, the probe holder 4 includes a back plate 41 and a clamping plate 42. The back plate 41 and the clamping plate 42 are connected by four support rods 43 to form a frame structure. The back plate 41 is used to connect the push-pull rod 23 and the fixing rod 31, and the clamping plate 42 is used to install the spring probe 5. This design ensures the structural stability of the probe holder 4.

[0032] As a specific implementation method, a positioning post 7 is also provided on the upper surface of the middle part of the chassis 1. Generally, the bottom of the power cabinet 8 to be tested has positioning holes. The positioning post 7 cooperates with the positioning holes to form a positioning, which makes it convenient for the staff to install the power cabinet 8 to be tested onto the chassis 1. When the staff needs to install the power cabinet 8 to be tested onto the chassis 1, they only need to align the positioning holes on the bottom of the power cabinet 8 to be tested with the positioning post 7 and place it on the chassis. The operation is simple and improves work efficiency.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
