[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1, referring to Figure 1-2 and Figure 4A test harness for battery pack charge and discharge testing in the energy storage industry includes a mating plate 1 and a harness organizer. The top outer wall of the mating plate 1 is fixed with a handle 2 by bolts. The side wall of the mating plate 1 is fixed with a low-voltage connector female end 3, two bushings 4 and a high-voltage connector 5 by bolts in sequence. The two bushings 4 are used to mate with the positioning pin to improve the mating accuracy. A low-voltage connector male end 6, a first high-voltage connector male end 7 and a second high-voltage connector male end 8 are arranged in sequence on one side of the mating plate 1. The low-voltage connector male end 6 is electrically connected to the low-voltage connector female end through a low-voltage harness 19. The first high-voltage connector male end 7 and the second high-voltage connector male end 8 are both electrically connected to the high-voltage connector 5 through a high-voltage harness 18. A pressing rod 17 is rotatably connected to the second high-voltage connector male end 8 by a rotating pin.
[0023] In this embodiment, by integrating the high-voltage connector and the low-voltage connector onto the docking plate 1, a rapid changeover effect can be achieved during the testing process, which facilitates better adaptation to different battery packs and connections between testing equipment, and helps to improve testing efficiency.
[0024] Example 2, refer to Figure 1 and Figure 3 This embodiment is an optimization based on embodiment 1. Specifically, it is a test harness for battery pack charge and discharge testing in the energy storage industry, and also includes a harness organizer.
[0025] Specifically, the wire harness organizer includes a wire rack 9, a mounting bracket 10 fixedly connected to the side wall of the wire rack 9, a bidirectional screw 11 rotatably mounted in the mounting bracket 10, two centering rods 12 symmetrically screwed to the two opposite thread ends of the bidirectional screw 11, a guide bracket 15 fixedly connected to the side wall of the wire rack 9, and three wire pressing assemblies disposed between the two centering rods 12.
[0026] Furthermore, each of the three wire pressing assemblies includes an upper wire pressing block 13 and a lower wire pressing block 14 symmetrically welded to the outer wall of opposite sides of the two centering rods 12. Both the upper wire pressing block 13 and the lower wire pressing block 14 have C-shaped slots on opposite sides, and the two C-shaped slots are symmetrically distributed. The cable management frame 9 has three wire holes, through which two high-voltage wire harnesses 18 and one low-voltage wire harness 19 pass respectively.
[0027] Furthermore, a rotating cap 16 is fixedly connected to the top outer wall of the three-way double screw 11, and guide holes are provided on both centering rods 12, and both guide holes are slidably connected to the guide frame 15.
[0028] In this embodiment, the bidirectional screw 11 is rotated by the rotating cap 16. Then, under the guidance of the guide frame 15, the two centering rods 12, which are threadedly connected to the bidirectional screw 11, will drive the three upper pressure wire blocks 13 and the three lower pressure wire blocks 14 to center and move closer together. This will press and fix the two high-voltage wire harnesses 18 and one low-voltage wire harness 19 that pass through the three wire holes. This will effectively and orderly organize the multiple wire harnesses and effectively avoid the situation of mutual entanglement and interference between the multiple wire harnesses.
