[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0017] like Figure 1-4 As shown, the utility model provides a wiring harness testing device, including a long strip test bench 1, a mounting groove 1-1 is opened on the top of the test bench 1 along its length direction, an electric heating rod 2 is installed between the groove walls at both ends of the mounting groove 1-1, and a wiring harness fixing frame with an angle adjustment is installed near the top of one end of the test bench 1. The wiring harness fixing frame includes a fixing bar 3, one end of the fixing bar 3 is installed on the test bench 1, a wiring harness fixing groove 3-1 is opened on the top of the fixing bar 3 along its length direction, a plurality of through holes 3-2 arranged in a rectangular array are opened at the bottom of the wiring harness fixing groove 3-1, and two clamping structures are provided on the fixing bar 3.
[0018] In order to achieve angle adjustment of the fixing bar 3, two ear plates 4 arranged front and back are fixed to the top of the test bench 1 near one end thereof, and a mounting column 5 is fixed between the two ear plates 4 near their upper ends. One end of the fixing bar 3 is mounted on the mounting column 5, and the mounting column 5 is a threaded column. A threaded hole matching the threaded column is opened at one end of the fixing bar 3, and a rotational clearance is left between one end of the fixing bar 3 and the two ear plates 4.
[0019] In order to clamp the wiring harness in the wiring harness fixing groove 3-1, the clamping structure includes a sliding sleeve 6 slidably installed on the fixing bar 3, and a vertical bolt 7 is threadedly installed on the top of the sliding sleeve 6. The lower end of the bolt 7 extends into the wiring harness fixing groove 3-1 and is fixed with a clamp 8.
[0020] The working principle of the present invention is described in detail below: screw the bolt 7 upward, then the wire harness can be straightened and placed in the wire harness fixing groove 3-1, push the sliding sleeve 6 to slide along the fixing strip 3 until the sliding sleeve 6 is above the two ends of the wire harness, screw the bolt 7 downward, drive the clip 8 to move downward until the clip 8 is clamped on the wire harness, thereby fixing the wire harness and, at the same time, fixing the sliding sleeve 6 on the fixing strip 3. Then the electric heating rod 2 can be connected to the external power supply to start heating, rotate the entire fixing strip 3, and rotate the fixing strip 3 around the mounting post 5 to adjust the angle. After adjustment, the entire fixing strip 3 will be fixed at a certain angle through the cooperation of the mounting post 5 and the threaded hole. At this time, the electric heating rod 2 heats the parts of the wire harness at different heights through the through hole 3-2, and the temperature resistance of the wire harness can be judged by observing the surface condition of the wire harness.
[0021] Finally, the most important contribution of the present invention is that the fixing strip 3 can be adjusted in angle on the test bench 1 to fix the wiring harness in the wiring harness fixing groove 3-1, and the wiring harness can be tested at different temperatures at one time, with a simple structure and high practicality.
