[0034] The box door 12 is provided with a control panel 17 equipped with digital display and operation buttons, which is used to set and monitor the experimental parameters of the constant temperature and humidity control system 14 and the heating system 15.
[0035] In order to facilitate real-time observation of the progress of the experiment, the box door 12 is also provided with a transparent plate 18, which facilitates the observation of the progress of the experimental cavity 11 by the staff.
[0036] As shown in Figures 2-3 In order to stabilize the wire harness to be tested, the experimental cavity 11 is provided with a wire releasing mechanism 2, which has a fixed rod 21 rotatably connected to the bottom of the experimental cavity 11. The upper end of the fixed rod 21 is fixedly installed with a wire harness support 22. The outer side of the wire harness support 22 is fixedly installed with a fixed ring 29. The lower end of the fixed ring 29 is uniformly fixedly installed with a placement plate 23. The placement plate 23 is used to place the wire harness to be tested.
