[0045] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0046] This utility model relates to a soft-pack battery insulation isolation testing device for centralized installation and testing of soft-pack batteries; by arranging and installing insulating mounting plates 2 on the supporting main board 1, the space utilization is improved; the longitudinal positioning component provides a limit reference, improving the consistency of the clamping position of the test clamp group 4 holding the electrode tabs of the soft-pack battery under test; the insulating partition 6 makes the batteries under test 5 mutually insulated and isolated; the overall structure is simple and easy to use, and can solve the problems of low space utilization, lack of positioning points and easy short circuit.

[0047] A soft-pack battery insulation isolation testing device, specifically, such as Figures 1-6 As shown, the device includes a support mainboard 1 and an insulating mounting plate 2. The support mainboard 1 is preferably a tray with side panels along its edges. The insulating mounting plates 2 are arranged laterally on the support mainboard 1. The insulating mounting plates 2 are provided with a test clamp group 4, a battery mounting position, and a longitudinal positioning member located on the side of the test clamp group 4 near the battery mounting position. The test clamp group 4 is preferably a polymer integrated clamp. The two longitudinal positioning members are located on the lateral sides of the test clamp group 4, with a gap between them for the battery tabs to pass through. The support mainboard 1 is provided with an insulating partition 6 located between the laterally adjacent insulating mounting plates 2. The insulating partition 6 is used to laterally limit the soft-pack battery under test, preventing the battery under test 5 from contacting and affecting the test during operation.

[0048] In one embodiment, the longitudinal positioning element is described, such as... Figures 5-6 As shown, the longitudinal positioning component includes an insulated positioning insert plate 3, and an insulated mounting plate 2 has a positioning insertion hole 23. The positioning insert plate 3 is interference-fitted and fixed in the positioning insertion hole 23. The longitudinal positioning component has a simple structure, and its installation on the insulated mounting plate 2 via the interference fit of the positioning insert plate 3 is convenient and easy to manufacture.

[0049] Based on the longitudinal positioning element, including the insulated positioning insert 3, such as Figure 1 and Figure 3 As shown, the supporting motherboard 1 has a clearance hole 15 corresponding to the positioning socket 23, and one end of the positioning plate 3 passes through the positioning socket 23 and is located inside the clearance hole 15. The clearance hole on the supporting motherboard allows the positioning plate to pass through the positioning socket, making the connection more stable.

[0050] Based on the longitudinal positioning element, including the insulated positioning insert 3, such as Figure 8As shown, the positioning insert 3 includes a positioning baffle 31 and an insertion plate 32 fixed to the positioning baffle 31. The positioning baffle 31 has a limiting surface 33 on one side where the insertion plate 32 is located, used to abut against the insulating mounting plate 2 to limit the insertion length. In one specific embodiment, the insertion plate 32 is integrally formed on the end face of the positioning baffle 31, so that the remaining surface of that end face of the positioning baffle 31 forms the limiting surface 33, facilitating production. The structure of the positioning insert 3 is very simple. The insertion plate 32 is inserted and fixed onto the insulating mounting plate 2, the positioning baffle 31 provides longitudinal positioning of the soft-pack battery, and the limiting surface 33 abuts against the insulating mounting plate 2 to limit the insertion length. This avoids unstable fixing due to excessively short insertion and insufficient insertion due to excessively long insertion, where the portion of the positioning baffle 31 protruding from the insulating mounting plate 2 is too low, thus affecting the limiting effect.

[0051] The positioning insert 3 includes a positioning baffle 31 and an insertion plate 32, such as Figure 8 As shown, the end of the plug-in plate 32 away from the positioning baffle 31 is provided with a chamfered structure, including one or two corners of the plug-in plate 32 being chamfered, which facilitates the insertion into the positioning socket 23.

[0052] In a preferred embodiment, such as Figure 1 As shown, multiple insulating mounting plates 2 are fixed to the support main plate 1 in a matrix arrangement, that is, the insulating mounting plates 2 are arranged at intervals in the horizontal and vertical directions; insulating partitions 6 are provided between horizontally adjacent insulating mounting plates 2 and on the back side of the insulating mounting plates 2 at both ends of the horizontal direction. Preferably, in order to improve the limiting effect, multiple insulating partitions 6 are provided longitudinally at intervals on one side of the insulating mounting plates 2. Conventional support main plates 1 are mostly metal plates, and contact with the soft-pack battery under test will affect the test. The matrix arrangement of the insulating mounting plates 2 has a higher space utilization rate. The insulating partitions 6 are also provided on the back side of the insulating mounting plates 2 at both ends of the horizontal direction, which can prevent the batteries 5 under test at both ends of the horizontal direction from slipping out of the insulating mounting plates 2 and causing a short circuit.

[0053] In some embodiments, such as Figures 4-7 As shown, the test clamp assembly 4 is fixedly provided with an L-shaped hook 41 and a fixing hole 42. The insulating mounting plate 2 is provided with a hanging hole 22 and a mounting hole 21. The hanging hole 22 can pass through the hook 41 and is abutted and limited by the hanging hole 22 in the horizontal or vertical direction. The fixing hole 42 is connected to the mounting hole 21 when the hook 41 slides into the insulating mounting plate 2 through the hanging hole 22. Preferably, the test clamp assembly 4 is provided with two hooks 41 and the insulating mounting plate 2 is provided with two corresponding hanging holes 22 to improve the stability of the fixed connection. When the test clamp assembly 4 is fixed, the insulating mounting plate 2 is fitted between the hook 41 and the test clamp assembly 4, and then bolted to the insulating mounting plate 2 through the fixing hole 42. The installation method is simple and the fixation is reliable.

[0054] Based on the fact that test clamp 4 is equipped with hook 41, such as Figure 5As shown, the test clamp group 4 includes a positive test clamp and a negative test clamp fixed together side by side. The side-by-side arrangement of the positive and negative test clamps ensures the consistency of the battery tabs and allows for fixed connection to the insulating mounting plate 2 via the same fixing hole 42. Preferably, the support mainboard 1 has a relief groove 13 at the mounting location of the test clamp group 4 to accommodate the hook 41. This eliminates the need for a groove at the bottom of the insulating mounting plate 2 to accommodate the hook 41, preventing the hook 41 from protruding from the bottom of the insulating mounting plate 2 and thus ensuring the insulating mounting plate 2 can be mounted flat on the support mainboard 1.

[0055] In one embodiment, the insulating partition 6 and the positioning insert 3 have the same structure, but their sizes may be the same or different; the main support board 1 is provided with a partition insertion hole 16, and the insulating partition 6 is inserted and fixed in the partition insertion hole 16. The insulating partition 6 and the positioning insert 3 have the same structure, which facilitates the production and assembly of this test device and reduces production costs.

[0056] In a preferred embodiment, such as Figures 1-3 As shown, a wiring channel 11 is provided on one side of the supporting motherboard 1 corresponding to the insulating mounting plate 2; a cable tie hole 2 is provided on one side of the wiring channel 11 on the supporting motherboard 1. Through the wiring channel 11 of the supporting motherboard 1, the test wire can be passed through the wiring channel 11 to the bottom of the supporting motherboard 1, keeping the table surface clean, tidy and beautiful; through the cable tie hole 2, cable ties can be used to fix the test wire to the supporting motherboard 1.

[0057] Preferably, such as Figures 5-6 As shown, the insulating mounting plate 2 has multiple countersunk holes 24, and the supporting main plate 1 has multiple rivet nut holes 14 corresponding to the countersunk holes 24. The rivet nut holes 14 are internally threaded with countersunk screws that pass through the countersunk holes 24.

[0058] Optionally, the insulating mounting plate 2 may be made of epoxy resin or fiberglass.

[0059] In actual use, the insulating mounting plates 2 are arranged in a matrix and fixed on the supporting main board 1. The supporting main board 1 has a wiring channel 11 on one side of the insulating mounting plate 2. The insulating mounting plates 2 have hanging holes 22 and mounting holes 21. The test clamp group 4 is fixed to the insulating mounting plate 2 through L-shaped hooks 41 and fixing holes 42. The positioning inserts 3 are respectively interference-fitted into the insulating mounting plates 2, with gaps on both sides of the test clamp group 4 for the battery tabs to pass through. The supporting main board 1 has an insulating partition 6 (positioning insert 3) interference-fitted into each insulating mounting plate 2 on both sides. During testing, the soft-pack battery is placed on the battery mounting position and abuts against the positioning insert 3, so that the insulating partitions 6 on both sides separate the adjacent batteries 5 to be tested. Then, the test clamp group 4 is used to clamp the battery tabs of the battery 5 to be tested. The operation is simple.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
