[0002] Multi-core cable harnesses refer to cables with more than one insulated core. Cables play an important role in electronic products and systems, serving as a key link connecting various functions of electronic products, and are widely used in aerospace, naval warfare, and other fields.

[0003] According to publication number CN222600548U, a multi-core wire and cable harness includes a multi-core cable harness with a protective component on its exterior. The protective component includes a protective tube fitted over the multi-core cable harness, a dividing tube in the middle of the protective tube, the multi-core cable harness fitted inside the dividing tube, an insulating support rod at the top center of the protective tube, a groove on one side of the insulating support rod, a telescopic rod at the bottom of the inner wall of the groove, a movable sleeve at the top of the telescopic rod, and several sets of trapezoidal clamping blocks around the outer wall of the movable sleeve. This invention utilizes a multi-core wire and cable harness, employing a dividing tube to separate the multi-core cable harness, trapezoidal clamping blocks to clamp the harness, and a protective insulating pad for anti-slip, thus providing support for one end of the harness and facilitating its protection.

[0004] The aforementioned separator tubes and other structures can separate multi-core cable bundles. However, since the multi-core cable bundles are located inside the separator tubes, they are prone to movement during use, which can affect their normal operation. Utility Model Content

The lower protective plate 16 is placed below the outer sheath 6, and the locking block 18 and the locking groove 19 are aligned. The lower protective plate 16 is pressed upward, so that the locking block 18 is engaged inside the locking groove 19. At the same time, the first support plate 15 and the second support plate 22 clamp the conductor body 1, thereby fixing the connection position of the conductor body 1 and the terminal 20 to prevent separation. A rubber pad 23 is provided on one side of the second support plate 22. Its deformation capability can fix conductor bodies 1 of different sizes, expanding the range of applications.

[0033] This utility model provides a multi-core wire harness, the specific working principle of which is as follows:
