The so-called DC cable is the conductor that transmits direct current. All wires connected to DC power sources can be collectively referred to as DC cables. Existing DC cables may be pulled during use, which may cause the DC to be damaged or broken, resulting in unnecessary losses, so improvements are needed. Utility Model Content

The wire body passes through the two ends of the buffer blocks and passes through the wire holes. An array of buffer components is arranged inside the buffer blocks, and a wire harness fixing mechanism is arranged on one of the buffer blocks.

[0005] Preferably, the number of the buffer blocks is not less than three.

[0006] Preferably, a magnetic sheet is provided on the surface of the buffer block.

[0007] Preferably, the buffer assembly includes an inner cylinder, a movable block is movably arranged inside the inner cylinder, one end of the movable block is connected to a buffer spring, the other end of the movable block is connected to a column, a wire sleeve is arranged on the top of the column, and the wire body passes through the wire sleeve.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model proposes a DC wire harness structure, in which a plurality of buffer blocks are arranged on a wire body, and a buffer assembly is arranged inside the buffer block. When the wire body is pulled, the wire bodies at both ends of the buffer block are subjected to tension, so that the wire body inside the buffer block moves outward, thereby causing the wire body to change from a bent state to a straight state. The buffer spring can be compressed to provide a buffer space, thereby reducing the influence of the pulling force and avoiding damage to the wire body. In addition, because a wire harness fixing mechanism is provided, when the wire body is not in use, a plurality of buffer blocks are adsorbed together by a magnetic sheet, and then the wire body is wound around the buffer block and fixed by a movable clamp block and a fixed clamp block, so as to facilitate the storage of the wire harness.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: a DC wire harness structure, including a wire body 1, a plurality of buffer blocks 2 are arranged on the wire body 1, the number of the buffer blocks 2 is not less than three, magnetic sheets 9 are arranged on the surface of the buffer blocks 2, the middle buffer block 2 is provided with magnetic sheets 9 on both sides, and the buffer blocks 2 at both ends are only provided with magnetic sheets 9 on one side, so that the buffer blocks 2 can be adsorbed and stacked together.

[0018] The buffer block 2 is a hollow structure. Wire holes 3 are provided on the side walls at both ends of the buffer block 2. The wire body 1 passes through both ends of the buffer block 2 and passes through the wire holes 3. An array of buffer components is provided inside the buffer block 2. The buffer component includes an inner tube 4. A movable block 5 is movably provided inside the inner tube 4. One end of the movable block 5 is connected to a buffer spring 6, and the other end of the movable block 5 is connected to a column 7. A wire sleeve 8 is provided on the top of the column 7. The wire body 1 passes through the wire sleeve 8. The wire body 1 is distributed in a W shape inside the buffer block 2. The inner walls of the wire sleeve 8 and the wire hole 3 are relatively smooth. The wire body 1 can slide in the wire sleeve 8 and the wire hole 3, so that the buffer block 2 can move on the wire body 1.

[0019] A wire harness fixing mechanism is arranged on one of the buffer blocks 2, and the wire harness fixing mechanism includes a slide groove 10, an inner slider 11 is movably arranged inside the slide groove 10, a side wall of the inner slider 11 is connected to a tightening spring 12, a movable clamping block 13 is connected to the top of the inner slider 11, a fixed clamping block 14 is arranged at an outer end of the slide groove 10, and a slot is arranged on the opposite side of the movable clamping block 13 and the fixed clamping block 14. The movable clamping block 13 is moved and then the wire body 1 is placed in the slot. Under the push of the tightening spring 12, the movable clamping block 13 and the fixed clamping block 14 can clamp and fix the wire body 1.

[0020] A plurality of buffer blocks 2 are arranged on the wire body 1, and a buffer assembly is arranged inside the buffer block 2. When the wire body 1 is pulled, the wire body 1 at both ends of the buffer block 2 is subjected to tension, so that the wire body 1 inside the buffer block 2 moves outward, thereby changing the wire body 1 from a bent state to a straight state. The buffer spring 6 can be compressed to provide a buffer space, thereby reducing the influence of the tension and avoiding damage to the wire body 1. In addition, because a wire harness fixing mechanism is arranged, when the wire body 1 is not in use, a plurality of buffer blocks 2 are adsorbed together by a magnetic sheet 9, and then the wire body 1 is wound around the buffer block 2 and fixed by a movable clamp 13 and a fixed clamp 14, so as to facilitate the storage of the wire harness.
