[0024] See also Figures 1 to 4 , the utility model provides a technical solution:

[0025] Embodiment 1, a DC distribution network distributed energy storage wiring structure, the DC distribution network distributed energy storage wiring structure includes: a mounting frame 1.

[0026] Specifically, the mounting frame 1 is fixedly connected to the power output device and a plurality of terminals 2 are fixedly connected to one side of the mounting frame 1, a plurality of mounting plates 3 corresponding to the number of the terminals 2 are fixedly connected to the side of the mounting frame 1, a fixing assembly 4 is fixedly connected to the upper end of the mounting plate 3, a plurality of buffer assemblies 5 are fixedly connected to the side of the mounting plate 3, a baffle 6 is fixedly connected to one end of the buffer assembly 5, and the baffle 6 can prevent the cable from being separated from the buffer assembly 5;

[0027] Furthermore, the buffer assembly 5 includes a mounting rod 51, which is located on the side of the mounting plate 3 and fixedly connected to the mounting plate 3. A plurality of telescopic rods 52 distributed in a circular array are fixedly connected to the side of the mounting rod 51, and a winding plate 54 is fixedly connected to one end of the telescopic rod 52. A plurality of springs 53 are fixedly connected between the winding plate 54 and the mounting rod 51. In actual implementation, the cable is first fixed to the terminal 2, and then the portion of the cable between the buffer assembly 5 and the terminal 2 is fixed by the fixing assembly 4 according to the height sequence of the cable. After the cable is fixed, the cable is wound around the winding plate 54 in circles, leaving enough space when winding. After the upper buffer assembly 5 is wound with enough cable, the cables are then wound in sequence. The wire is wound around the lower buffer component 5. Of course, when the cable is wound around the buffer component 5, the winding force needs to be controlled, and the spring 53 cannot be compressed too much. After the winding is completed, when an external force pulls the cable, the cable will first apply pressure to the winding plate 54 on each buffer component 5 from bottom to top in sequence, and then the winding plate 54 will compress the spring 53, so that the cable inside the power output device can have an additional buffer length, thereby reducing the probability of the wiring structure being damaged. After the fixing component 4 fixes the part of the cable between the buffer component 5 and the terminal 2, when the maximum buffer length is reached, the cable will also first apply force to the fixing component 4, thereby further improving the safety of the wiring structure.

[0028] In order to improve the safety of the cable, the positive corners of the winding plate 54 of the present application that contact the cable are all set to "rounded corners", so as to prevent the positive corners of the winding plate 54 from wearing the outer packaging layer of the cable, and multiple springs 53 and telescopic rods 52 are correspondingly socketed.

[0029] In order to better separate the cables, a plurality of protrusions 55 are fixedly connected to one side of the winding plate 54 of the present application, and the plurality of protrusions 55 are distributed in a linear array on the side of the winding plate 54, so that the cables can be separated between the protrusions 55, thereby avoiding the trouble of shrinkage when the cables are wound and stacked together.

[0030] In order to more conveniently fix the cable, the fixing assembly 4 of the present application includes a winding rod 41, which is located at one end of the mounting plate 3 and fixedly connected to the mounting plate 3, the winding rod 41 is arranged in an "L" shape and an adjusting bolt 42 is threadedly inserted at one end of the winding rod 41, a No. 1 clamping plate 43 is fixedly connected to the side of the winding rod 41, and a No. 2 clamping plate 44 is fixedly connected to the side of the adjusting bolt 42. After the cable is fixed on the terminal 2, first wrap a part of it tightly around the winding rod 41, and then rotate the adjusting bolt 42 to drive the No. 2 clamping plate 44 to slide toward the end of the No. 1 clamping plate 43, and the cable is fixed by the cooperation of the No. 1 clamping plate 43 and the No. 2 clamping plate 44.

[0031] In order to facilitate the installation of the adjusting bolt 42 and the second clamping plate 44, a plurality of extension rods 46 are fixedly connected between the adjusting bolt 42 and the second clamping plate 44 of the present application, and a threaded hole 45 for threaded insertion of the adjusting bolt 42 is provided at one end of the winding rod 41. The threaded hole 45 can facilitate the threaded insertion of the adjusting bolt 42, and the extension rod 46 can provide installation space for the second clamping plate 44 without affecting the rotation of the adjusting bolt 42.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
