Description

Technical Field

[0001] The utility model belongs to the technical field of HDMI high-definition line production equipment, in particular to a TDR testing device used for HDMI high-definition line production. Background Art

[0002] The production process of HDMI high-definition cables requires the cooperation of multiple equipment, including detection equipment for detecting HDMI high-definition cables. Among the above-mentioned detection equipment, the TDR test device is the most representative. The TDR test is radar detection, which is used to detect whether there are breakpoints in the HDMI high-definition cable, and can also locate the breakpoints.

[0003] Existing document CN218848237U-A TDR test device for a wiring harness, which discloses: a TDR test device for a wiring harness, comprising a TDR tester, a display screen installed on the front surface of the TDR tester, a power interface installed on one side of the TDR tester, and a plurality of test ports installed on the front surface of the TDR tester; grooves are provided on the front surface of the TDR tester and at the top and bottom of the test port, and two groups of first cylinders are symmetrically embedded in the grooves; when the utility model is used, a retractable wiring harness limiting shielding mechanism is installed at the test port of the TDR tester, and the wiring harness limiting shielding mechanism is retracted by using the first cylinder, the second cylinder and the L-shaped rod. When the wiring harness is connected to the test port for TDR testing, the wiring harness can pass through the limiting rings at the opposite ends of the two L-shaped rods and be connected in the test port, and the corrugated tube is driven by stretching the L-shaped rod to stretch and cover one end of the wiring harness, and the shaking angle of the wiring harness is limited, thereby avoiding shaking of the wiring harness at the test port when the TDR test is performed. However, it still has the following disadvantages in actual use:

[0004] 1. The TDR test device for the wiring harness has a first cylinder installed on its test port, and a second cylinder that can be stretched at will is slidably installed inside the first cylinder. The cooperation between the first cylinder and the second cylinder ensures that the wiring harness can shuttle freely inside it, and completes the segmented TDR test of the long wiring harness. However, no auxiliary wiring harness shuttle device is set at both ends of the first cylinder and the second cylinder, that is, when performing TDR test on the wiring harness, it is necessary to manually pull the wiring harness to walk inside it, which leads to the problem that it is not conducive to the continuous progress of the test work;

[0005] 2. When using the above-mentioned TDR test device for the wire harness, it is first necessary to insert the wire harness into the first cylinder, and then adjust the total length of the second cylinder and the first cylinder according to the length of the wire harness. After the TDR test is completed, the wire harness is pulled out of the device from the other end of the second cylinder, that is, the automatic loading and unloading of the wire harness cannot be completed.
