[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figures 1 to 5This utility model provides a DC cable harness with good bending resistance, comprising a cable harness body 7, connecting seats 2 fixedly connected to both sides of the cable harness body 7, mounting seats 3 fixedly connected to the outer surface of the connecting seats 2 away from the cable harness body 7, connecting seats 8 fixedly connected to both sides of the mounting seats 3, a first spring 11 fixedly connected to the inner surface of the connecting seats 8, a guide block 12 fixedly connected to one end of the first spring 11, the guide block 12 and the inner surface of the connecting seats 8 being slidably connected, a protective sleeve 9 fixedly connected to the side surface of the guide block 12, a connecting post 13 fixedly connected to the upper surface of the protective sleeve 9, a fixing seat 16 fixedly connected to the upper surface of the protective sleeve 9, a through vertical groove opened on the upper surface of the mounting seat 3 near the connecting post 13, a through horizontal groove opened on the upper surface of the mounting seat 3 near the fixing seat 16, a connecting plate 14 fixedly connected to the connecting post 13 through the through vertical groove, and an anti-slip strip 4 made of rubber fixedly connected to the upper surface of the connecting plate 14. When subjected to bending, the silicone connecting sleeve 1 absorbs the stress generated, thereby enhancing the bending resistance to a certain extent.

[0019] The upper surface of the first telescopic rod is fixedly connected to the lower surface of the limiting plate 15. The second telescopic rod is fixedly connected to the inner surface of the connecting seat 8 near the first spring 11. The limiting plate 15 and the inner surface of the fixed seat 16 are slidably connected. The first telescopic rod is fixedly connected to the lower inner surface of the fixed seat 16 near the second spring 17. The second spring 17 is fixedly connected to the lower inner surface of the fixed seat 16. One end of the second spring 17 is fixedly connected to the limiting plate 15. After using the device, simply press down the limiting plate 15. The second spring 17 is compressed, and the limiting plate 15 slides within the fixed seat 16. One end of the limiting plate 15 moves away from the through transverse groove. After disengagement, the first spring 11 immediately rebounds, causing the protective sleeve 9 to reset. The protective sleeve 9 protects the first connecting end 5 and the second connecting end 10 connected to the connecting seat 2, reducing the probability of damage due to external pressure.

[0020] A silicone connecting sleeve 1 is wrapped around the outer surface of the wire harness body 7 at the end away from the mounting base 3. The lower surface of the protective sleeve 9 is slidably connected to the lower inner surface of the mounting base 3. A first connecting end 5 is fixedly connected to the side surface of one of the connecting bases 2 at the point away from the second connecting end 10. A label 6 is fixedly connected to the upper surface of the connecting base 2. The side surface of the second telescopic rod and the side surface of the guide block 12 are fixedly connected. The second connecting end 10 is fixedly connected to the side surface of the connecting base 2 at the point away from the wire harness body 7. When a finger presses the connecting plate 14, it will come into contact with the anti-slip strip 4 on the upper surface of the connecting plate 14. The rubber anti-slip strip 4 can enhance the friction between the finger and the skin, thereby improving the ease of operation.

[0021] Working principle: When the wire harness is not in use, the protective sleeve 9, under the action of the first spring 11, is always located at the far end of the mounting base 3, covering the connecting base 2 and its corresponding second connecting end 10 and first connecting end 5, thus providing protection. When the device is needed for data transmission or other operations, the connecting plate 14 is pressed in the opposite direction. The connecting post 13 connected to the connecting plate 14 causes the protective sleeve 9 to slide within the mounting base 3, approaching the wire harness body 7, thereby exposing the second connecting end 10 and the first connecting end 5 for easy connection to the device. During the sliding process, the first spring 11 and the second spring 17 are compressed until the limiting plate 15 is aligned with the through transverse groove. The second spring 17 immediately rebounds, pushing one end of the limiting plate 15 into the through transverse groove, limiting the position of the protective sleeve 9 and facilitating device connection.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
