[0023] Specifically, the first side surface of the detection ruler 1 is provided with a limiting through groove 3, the limiting through groove 3 is in communication with any one of the detection grooves 2, please refer to Figure 2 , the limiting through groove 3 in the embodiment is in communication with the first detection groove 2, here the first detection groove 2 refers to Figure 2 the first detection groove 2 from left to right in the figure is in communication with the limiting through groove 3, the bottom end of the detection groove 2 in communication with the limiting through groove 3 is coplanar with the bottom end of the limiting through groove 3, the harness can enter the limiting through groove 3 through the detection groove 2, and the detection grooves 2 not in communication with the limiting through groove 3 are arranged at equal intervals with the limiting through groove 3.

[0024] Specifically, please refer to Figure 2 , the limiting through groove 3 is cuboid-shaped, which facilitates the harness to enter the limiting through groove 3 from the detection groove 2.

[0025] Specifically, please refer to Figure 3 , the limiting through groove 3 is cylindrical, which has a good fixing effect on the harness.

[0026] When the harness detection jig is used for harness detection of the PCB panel 4, first, the first harness 411 of the PCB module 41 in the first row and the first column of the PCB panel 4 is arranged in the first detection slot 2, then the first harness 411 is clamped into the limiting through slot 3 to limit and fix the first harness 411, and finally the remaining detection slots 2 are aligned with the harnesses of the remaining PCB modules 41 in the same row, and the detection ruler 1 shields the remaining harnesses, and since the detection slots 2 not in communication with the limiting through slot 3 are arranged at equal intervals with the limiting through slot 3, the harnesses aligned with the detection slots 2 except the first detection slot 2 should be the first harness 411 in theory, and the first harness 411 in the limiting through slot 3 and the harnesses aligned with the detection slots 2 are of the same color, and if the colors of any harnesses are different, it indicates that there is an error in the welding of the harnesses; similarly, the welding detection of the second harness 412, the third harness 413 and the fourth harness 414 can be performed, so that the welding detection of the harnesses of the PCB modules 41 in a row can be completed through four comparisons, which is more efficient than detecting the single PCB module 41 one by one, especially when a row includes a large number of PCB modules 41, a large amount of time can be saved, and since the operation and judgment are simple, the errors of the operators can be reduced.

[0027] Embodiment two

[0029] The use of the harness detection jig of the present embodiment can refer to the use of the harness detection jig in embodiment one, and since the detection slot 2 of the present embodiment is quadrangular prism-shaped and is provided with a cylindrical limiting through slot 3, the harness can be clamped into the limiting through slot 3, the limiting and fixing of the harness by the limiting through slot 3 can facilitate subsequent alignment work, which is equivalent to fixing a comparison reference.

[0030] Specifically, one limiting through groove 3 can also be arranged below each of the detection grooves 2, and the limiting through grooves 3 are arranged at equal intervals. In this way, all the limiting through grooves 3 can be used for fixing the wire harness, or only one of them can be used. Compared with arranging only one limiting through groove 3, this arrangement is more flexible to use.
