[0002] During the battery test, due to the differences in test equipment and battery models, testers may need to frequently replace batteries or adjust wiring harness connections. This frequent replacement and adjustment places very high demands on test efficiency and wiring harness management. Traditional battery test low-voltage wiring harness adapters usually use insulating materials to connect the power supply and battery. Although this method is simple and easy, it has many problems and inconveniences.

After the harness passes through the harness groove 10, it is fixed by the spring-loaded device 4. The harness is fixed and arranged by the harness fixing plate 3 and the spring-loaded device 4, so that the harness is neatly arranged and not easily confused, which improves the convenience of harness management.

[0027] Specifically, the spring-pressing device 4 includes a fixed box 11, a spring 12 and a clamping block 13, wherein the spring 12 and the clamping block 13 are arranged inside the fixed box 11, wherein one end of the spring 12 is connected to the clamping block 13, and the other end is connected to a fixed plate 14, wherein the fixed plate 14 is installed at the upper end of the fixed box 11. The spring-pressing device 4 fixes the wiring harness through the elasticity of the spring 12 and the squeezing effect of the clamping block 13, ensuring that the wiring harness will not fall off or loosen during the test. Due to the compressibility of the spring 12, the spring-pressing device 4 can adapt to wiring harnesses of different diameters. Regardless of the diameter of the wiring harness, the spring 12 can provide appropriate elastic force to make the clamping block 13 fit tightly to the wiring harness to achieve stable fixation. The design of the spring-pressing device 4 allows it to be reused.

[0030] In another embodiment, if Figure 6 As shown: the upper wiring harness plate 8 and the lower wiring harness plate 9 can also be tightly covered and fixed by connecting them with bolts 22. In this connection mode, corresponding bolt holes are pre-designed on the upper wiring harness plate 8 and the lower wiring harness plate 9.
