[0030] The utility model provides a fixture for testing soft-package batteries. Figure 1 and Figure 2 As shown, the fixture for testing soft-package batteries includes a first clamping plate body 1 , a second clamping plate body 2 and an insulating separator 3 .

[0031] In the following description, reference will be made to Figure 1 and Figure 2 The specific structure of the above components of the fixture for testing soft-package batteries and the connection relationship of the above components are specifically described.

[0032] like Figure 1 and Figure 2As shown, in an embodiment, the first clamping plate body 1 may be provided with a first receiving plate 11 and a second receiving plate 12. The second clamping plate body 2 may be arranged opposite to the first clamping plate body 1, so that the second clamping plate body 2 and the first clamping plate body 1 can clamp and fix the soft-package battery in the middle. The second clamping plate body 2 may be provided with a first pressing component 21 at a position corresponding to the first receiving plate 11, which is used to press the first pole tab of the soft-package battery and the current line of the charge and discharge tester onto the first receiving plate 11. The second clamping plate body 2 may be provided with a second pressing component 22 at a position corresponding to the second receiving plate 12, which is used to press the second pole tab of the soft-package battery and the current line of the charge and discharge tester onto the second receiving plate 12. The first pole tab and the second pole tab are respectively the positive pole tab and the negative pole tab of the soft-package battery, thereby the pole tab of the soft-package battery can be conductively connected to the current line of the charge and discharge tester without punching, so as to test the soft-package battery. In addition, an insulating partition 3 is provided between the first receiving plate 11 and the second receiving plate 12 to prevent a short circuit between the positive electrode tab and the negative electrode tab of the soft-package battery.

[0033] Preferably, Figure 1 and Figure 2 As shown, in the embodiment, the first and second clamping plate bodies 1 and 2 can be approximately rectangular parallelepiped plates. The first and second clamping plate bodies 1 and 2 can be of equal size. Preferably, the surfaces of the first and second clamping plate bodies 1 and 2 can be coated with an insulating coating to prevent electrical conduction between the first and second clamping plate bodies 1 and 2 and the soft-package battery.

[0034] Preferably, Figure 1 As shown, in this embodiment, placement grooves 4 may be provided on opposing sides of the first and second clamping plate bodies 1 and 2. Specifically, inwardly recessed rectangular grooves may be formed on the surfaces of the first and second clamping plate bodies 1 and 2 for receiving the soft-packaged batteries. This allows the soft-packaged batteries to be retained within the placement grooves 4 when the first and second clamping plate bodies 1 and 2 are clamped together.

[0035] More preferably, Figure 1 and Figure 2As shown, in an embodiment, a plurality of wire-accommodating grooves 5 can be provided on the opposite sides of the first splint body 1 and the second splint body 2 for accommodating temperature-sensitive wires. Since the temperature-sensitive wires need to be adhered to the surface of the soft-package battery for temperature sampling when the soft-package battery is tested. In the past, the soft-package battery to be tested was usually clamped directly. Affected by the clamping force, the temperature-sensitive wire will leave compression marks on the surface of the soft-package battery, causing certain deformation to the soft-package battery. When the temperature-sensitive wire is set in the wire-accommodating groove 5, the first splint body 1 and the second splint body 2 can make the temperature-sensitive wire close to the surface of the soft-package battery to avoid squeezing and leaving indentations. Preferably, the number of wire-accommodating grooves 5 can be multiple. As Figure 1 As shown, multiple wire-accommodating grooves 5 can be arranged in a staggered manner in the vertical and horizontal directions, so that the temperature-sensing wire can be placed in a desired position. In addition, the wire-accommodating grooves 5 can connect the placement groove 4 with the ends of the first clamping plate body 1 and the second clamping plate body 2 to prevent the temperature-sensing wire from bending during the temperature measurement process.

[0036] Preferably, Figure 1 and Figure 2 As shown, in an embodiment, the first receiving plate 11 and the second receiving plate 12 can be arranged at intervals on the upper part of the first splint body 1. Specifically, the first receiving plate 11 and the second receiving plate 12 can be integrally formed with the top of the first splint body 1. The thickness of the first receiving plate 11 and the second receiving plate 12 can be equal to the thickness of the first splint body 1, and the shape of the first receiving plate 11 and the second receiving plate 12 can be a strip plate with an arc-shaped end. A rectangular insulating partition 3 can be provided between the first receiving plate 11 and the second receiving plate 12. The insulating partition 3 can protrude from the plate surface of the first splint body 1 opposite to the second splint body 2, so that the insulating partition 3 can separate the first receiving plate 11 from the second receiving plate 12, thereby avoiding short circuit of the tabs of the soft-package battery during the test.

[0037] Preferably, Figure 1 and Figure 2As shown, in this embodiment, the first pressing component 21 is used to press the first tab of the soft-pack battery and the current line against the first receiving plate 11. The second pressing component 22 is used to press the second tab of the soft-pack battery and the current line of the charge and discharge tester against the second receiving plate 12. Specifically, the first pressing component 21 may include a first chute 211, a first slider 212, and a first pressing plate 213. The second pressing component 22 may include a second chute 221, a second slider 222, and a second pressing plate 223. The first chute 211 may be provided at the top of the second clamping plate body 2, and the direction in which the first chute 211 extends may be perpendicular to the surface of the first receiving plate 11. The first slider 212 may be retained within the first chute 211, allowing the first slider 212 to slide along the first chute 211. The first pressing plate 213 may be provided at the end of the first slider 212 proximal to the first receiving plate 11, with the surface of the first pressing plate 213 facing the surface of the first receiving plate 11. Preferably, the shape of the first pressing plate 213 can be the same as that of the first receiving plate 11. When the first clamping component 21 approaches the direction of the first receiving plate 11, the first pressing plate 213 can press the first pole ear and the current line onto the first receiving plate 11. Similarly, the second slide groove 221 can be opened at the top of the second clamping plate body 2, and the extension direction of the second slide groove 221 can be perpendicular to the plate surface of the second receiving plate 12. The second slider 222 can be clamped in the second slide groove 221, so that the second slider 222 can slide along the second slide groove 221. The second pressing plate 223 can be arranged at the end of the second slider 222 close to the second receiving plate 12, and the plate surface of the second pressing plate 223 is arranged opposite to the plate surface of the second receiving plate 12. Preferably, the shape of the second pressing plate 223 can be the same as that of the second receiving plate 12. When the second pressing component 22 approaches the second receiving plate 12 , the second pressing plate 223 can press the second electrode tab and the current wire onto the second receiving plate 12 .

[0038] More preferably, Figure 1 and Figure 2 As shown, in an embodiment, the top of the second clamping plate body 2 may further be provided with an escape groove 6. Specifically, the escape groove 6 may be a rectangular groove, and the width of the escape groove 6 may be equal to the width of the insulating partition 3. The escape groove 6 may be located between the first chute 211 and the second chute 221, so that the position of the escape groove 6 corresponds to the position of the insulating partition 3. When the first clamping plate body 1 and the second clamping plate body 2 are close to each other, the end of the insulating partition 3 can pass through the escape groove 6, thereby avoiding interference with the second clamping plate body 2.

[0039] Preferably, Figure 1 and Figure 2As shown, in the embodiment, a connecting rod may be further provided between the first splint body 1 and the second splint body 2, and the connecting rod may be provided through the first splint body 1 and the second splint body 2. Such an arrangement enables the first splint body 1 and the second splint body 2 to move along the connecting rod, thereby playing a guiding role.

[0040] Further, preferably, Figure 1 and Figure 2 As shown, the connecting rod can be a bolt 7. The number of bolts 7 can be four, and the four bolts 7 can be respectively passed through the four corners of the first splint body 1 and the second splint body 2. In addition, locking nuts 70 for limiting can be installed at both ends of the bolt 7. The locking nuts 70 can be set on the sides away from each other of the first splint body 1 and the second splint body 2. When the first splint body 1 and the second splint body 2 are moved into place, the first splint body 1 and the second splint body 2 can be limited by screwing the locking nuts 70 to clamp the soft-package battery.

[0041] During use, the operator can first place the temperature sensing wire into the desired position in the wire holding slot 5. Then install the soft-package battery in the placement slot 4 so that the pole ear of the soft-package battery fits with the first receiving plate 11 and the second receiving plate 12. Then install the bolt 7 on the first clamping plate body 1 and the second clamping plate body 2, and screw the locking nut 70 according to the clamping force required by the soft-package battery. Then place the current wire of the charge and discharge tester on the pole ear of the soft-package battery, and finally push the first clamping part 21 and the second clamping part 22 so that the current wire fits tightly with the pole ear to test the soft-package battery. After the test is completed, the first clamping part 21 and the second clamping part 22 can be reset first, and then the bolt 7 and the locking nut 70 can be removed, and finally the soft-package battery can be taken out.

[0042] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The scope of protection of the present application is not limited thereto.
