[0043] As shown in Figure 1 and Figure 2 The utility model provides a wiring board 100, including board main body and conductive column 130. Among them, the board main body is set with slide groove 110 and wiring groove 120, is provided with a plurality of slide grooves 110, a plurality of slide grooves 110 are sequentially arranged along the first direction X, and the length direction of slide groove 110 is parallel with the second direction Y, and two probe modules 200 can be placed in each slide groove 110;Wiring groove 120 includes positive pole groove 120a and negative pole groove 120b, and positive pole groove 120a and negative pole groove 120b communicate a plurality of slide grooves 110, positive pole groove 120a is used to set positive pole wire harness, and one end of positive pole wire harness is electrically connected with one probe module 200, and negative pole groove 120b is used to set negative pole wire harness, and one end of negative pole wire harness is electrically connected with another probe module 200;Conductive column 130 includes positive pole column 131 and negative pole column 132, and positive pole column 131 is at least partially installed in positive pole groove 120a and is used to connect with the other end of a plurality of positive pole wire harnesses, and negative pole column 132 is at least partially installed in negative pole groove 120b and is used to connect with the other end of a plurality of negative pole wire harnesses;The first direction X is perpendicular to the second direction Y.

The wiring board 100 has multiple slots 110, enabling current testing of multiple battery cells 2, thus improving testing efficiency. Furthermore, the wiring board 100 has wiring grooves 120, where the wire harnesses of the probe modules 200 are placed to prevent scattering.

The positive terminal 131 can be electrically connected to multiple positive wire harnesses, and the negative terminal 132 can be electrically connected to multiple negative wire harnesses.

When the positive terminal 131 and the negative terminal 132 are connected to the power supply, the probe modules 200 located in different slides 110 form a parallel connection and are independently switched on and off.

[0045] Optionally, the main body of the board can be made of an insulator. This design can prevent short circuits caused by connections between the positive and negative terminals.

[0046] In other embodiments, an insulating layer is provided in the groove 110 and the wiring groove 120.

[0047] Optionally, in the second direction Y, the positive electrode slot 120a and the negative electrode slot 120b are located on opposite sides of the slide groove 110.

[0050] Optionally, the main body of the plate is also provided with a guide groove 140. The length direction of the guide groove 140 is parallel to the length direction of the slide groove 110. Multiple guide grooves 140 are provided, and each slide groove 110 is provided with at least one guide groove 140. The guide groove 140 is located between two adjacent slide grooves 110.

[0051] For example, in the embodiment, each sliding groove 110 is provided with a guide groove 140 on opposite sides in the first direction X, and the probe module 200 can be at least partially inserted into the guide groove 140, so that the probe module 200 can be stabilized and the path of the probe module 200 moving along the sliding groove 110 can be standardized.

[0052] Optionally, in the first direction X, the positive pole column 131 and the negative pole column 132 are located on the same side of the plate body. In this way, the power supply or other electrical devices can be connected to the positive pole column 131 and the negative pole column 132.

[0053] Optionally, the wiring groove 120 includes branch sections 121 and trunk sections 122. The branch sections 121 are provided in plurality, and the branch sections 121 are arranged in sequence in the first direction X. One end of the branch section 121 is in communication with one end of the sliding groove 110 in the second direction Y. Part of the trunk section 122 extends in the first direction X and sequentially connects the other end of the plurality of branch sections 121. Another part of the trunk section 122 is provided with the conductive column 130.

[0054] In this way, the plurality of branch sections 121 converge in the same trunk section 122, which can reduce the number of grooves in the plate body, thereby improving the structural strength of the plate body. At the same time, it is also convenient for wiring and avoids the problem of short circuit caused by the entanglement of the wire harness.

[0055] Optionally, a chamfer is provided at the intersection of the branch section 121 and the trunk section 122. For example, the chamfer is a circular arc angle. In this way, when the positive pole wire harness converges from the branch section 121 to the trunk section 122, a smooth transition is formed at the intersection, reducing the bending of the wire harness. Similarly, when the negative pole wire harness converges from the branch section 121 to the trunk section 122, a smooth transition is formed at the intersection, reducing the bending of the wire harness.

[0056] As shown in Figure 3 A current testing device 1 is also provided, which includes the probe module 200 and the above-mentioned wiring plate 100. The probe module 200 is provided in plurality, and two probe modules 200 are arranged in each sliding groove 110.

[0057] Optionally, the current testing device 1 includes a base 300 and a lifting mechanism 400. The base 300 is provided with a plurality of mounting positions, each of which can accommodate an electric core 2. The plurality of mounting positions correspond to the plurality of sliding grooves 110 one by one. The lifting mechanism 400 is used to drive the wiring plate 100 to move closer to or farther away from the base 300 in the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. In this way, the current testing device 1 can test the current of a plurality of electric cores 2, improving the testing efficiency. Moreover, by using the above-mentioned wiring plate 100, the wiring layout can be simplified, and the short circuit caused by the mutual entanglement of the positive and negative pole wire harnesses can be avoided.

[0058] In addition, the above is only the preferred embodiment of the present application and the applied technical principle. The person skilled in the art can understand that the present application is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by the person skilled in the art without departing from the protection scope of the present application.
