All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1 The utility model provides a technical solution: a swing-resistant cable for an electric energy storage system, comprising a coating layer 1, a tensile connecting strip 2 is fixed to the inner wall of the coating layer 1, one end of the tensile connecting strip 2 is integrally formed on the surface of the center sleeve 3, copper foil wires 5 are arranged on both sides of the tensile connecting strip 2, alloy copper foil wires 6 are arranged inside the center sleeve 3, and a wear-resistant rubber strip 9 is integrally formed on the outer wall of the coating layer 1; the setting of the tensile connecting strip and the copper foil wire enhances the tensile strength of the cable, so that the cable is not easy to break when subjected to swing and vibration. At the same time, the copper foil wire also has excellent electrical conductivity, which ensures the stability of the electrical performance of the cable during the swing process; the alloy copper foil wire has higher strength and toughness, and can provide stronger support when the cable is subjected to external force. The filling strip is filled between the center sleeve and the alloy copper foil wire, which not only realizes the clamping and limiting of the alloy copper foil wire, but also improves the compressive performance of the center sleeve, so that the cable is not easy to deform when subjected to swing and vibration.

[0023] Embodiment 2

[0024] See attached Figure 3 to Figure 4 On the basis of Example 1, in order to limit the copper foil wire 5 inside the coating layer 1, a plurality of tensile connecting strips 2 are provided, and the plurality of tensile connecting strips 2 are arranged and distributed with the center sleeve 3 as the central axis. The copper foil wire 5 corresponds to the tensile connecting strip 2 one by one, and the copper foil wire 5 and the tensile connecting strip 2 are distributed alternately. A notch 11 is provided on the inner annular surface of the coating layer 1. The notch 11 is an arc-shaped groove, and the long side length of the notch 11 is equal to the long side length of the coating layer 1. A plurality of notches 11 are provided, and the notch 11 corresponds to the tensile connecting strip 2 one by one, and the notch 11 and the tensile connecting strip 2 are distributed alternately. Limiting grooves 4 are provided on both sides of the tensile connecting strip 2. The limiting grooves 4 are arc-shaped grooves, and the long side length of the limiting grooves 4 is equal to the long side length of the tensile connecting strip 2. The copper foil wire 5 is clamped in the limiting groove 4 between two adjacent tensile connecting strips 2; a through hole 8 is provided on the surface of the tensile connecting strip 2, and the through hole 8 is an oblong hole.

[0025] When the copper foil wire 5 is inside the coating 1, the copper foil wire 5 is clamped in the gap formed by two adjacent tensile connecting strips 2 and the coating 1 and the center sleeve 3. The reason for opening the notch 11 on the inner wall of the coating 1 and the limiting groove 4 on the surface of the tensile connecting strip 2 is to increase the contact area between the copper foil wire 5 and the coating 1 and the tensile connecting strip 2 to avoid the coating 1 and the tensile connecting strip 2 only forming a line of contact area for the copper foil wire 5, thereby ensuring that the copper foil wire 5 does not deflect in the coating 1, so that the tensile connecting strip 2 surrounds both sides of the copper foil wire 5, and at the same time plays a role in strengthening the swing resistance of the entire wire body.

[0026] Embodiment 3

[0027] On the basis of Example 2, in order to limit the alloy copper foil wire 6 inside the center sleeve 3, a filling strip 7 is integrally formed on the inner ring surface of the center sleeve 3. The filling strip 7 is an arc-shaped strip. The long side length of the filling strip 7 is equal to the long side length of the center sleeve 3. A plurality of filling strips 7 are provided. The plurality of filling strips 7 are distributed in a circle about the central axis of the center sleeve 3. The filling strips 7 are clamped between the alloy copper foil wire 6 and the center sleeve 3.

[0028] The reason why the filling strips 7 are installed inside the center sleeve 3 is that the filling strips 7 are filled between the center sleeve 3 and the alloy copper foil wire 6 to achieve the clamping and limiting of the alloy copper foil wire 6, and the space between two adjacent filling strips 7 constitutes an elastic structure distributed in the center sleeve 3, thereby improving the compressive resistance of the center sleeve 3, and when the entire wire body swings, the filling strips 7 also serve as a tensile and tearing-resistant structure.

[0029] Embodiment 4

[0030] See attached Figure 2 As shown, on the basis of Example 3, in order to improve the wear resistance of the coating layer 1, the wear-resistant rubber strip 9 is an arc-shaped strip, the long side length of the wear-resistant rubber strip 9 is equal to the long side length of the coating layer 1, and the surface of the wear-resistant rubber strip 9 is provided with a perforation 10. There are multiple wear-resistant rubber strips 9, and the multiple wear-resistant rubber strips 9 are distributed in a circle with the coating layer 1 as the center axis.

[0031] The reason for installing wear-resistant rubber strips 9 on the outer wall of the covering layer 1 is, firstly, to prevent direct wear between the covering layer 1 and the ground when the covering layer 1 contacts the ground, that is, the wear-resistant rubber strips 9 support the covering layer 1, and the perforations 10 inside the wear-resistant rubber strips 9 allow for the elastic deformation of the wear-resistant rubber strips 9, thereby providing a buffer when the entire wire falls on the ground; and multiple wear-resistant rubber strips 9 are enclosed on the outside of the covering layer 1 to enhance the tensile strength of the entire wire against swinging.

[0032] When in use, when the copper foil wire 5 is inside the coating layer 1, the copper foil wire 5 is clamped in the gap formed by two adjacent tensile connecting strips 2 and the coating layer 1 and the center sleeve 3. The reason why the notch 11 is opened on the inner wall of the coating layer 1 and the limit groove 4 is opened on the surface of the tensile connecting strip 2 is to increase the contact area between the copper foil wire 5 and the coating layer 1 and the tensile connecting strip 2, and avoid the coating layer 1 and the tensile connecting strip 2 forming only a line of contact area for the copper foil wire 5, thereby ensuring that the copper foil wire 5 does not deflect in the coating layer 1, so that the tensile connecting strip 2 surrounds both sides of the copper foil wire 5, and at the same time plays a role in strengthening the whole wire body against swaying; the reason why the filling strip 7 is installed inside the center sleeve 3, the filling strip 7 is filled in the center sleeve 3 The alloy copper foil wire 6 is clamped and limited between the wear-resistant rubber strips 9 and the alloy copper foil wire 6, and the space between two adjacent filling strips 7 constitutes an elastic structure distributed in the center sleeve 3, thereby improving the compression resistance of the center sleeve 3, and when the entire wire body swings, the filling strips 7 also serve as a tensile and tear-resistant structure; the reason why wear-resistant rubber strips 9 are installed on the outer wall of the coating layer 1 is to avoid direct wear between the coating layer 1 and the ground when the coating layer 1 contacts the ground, that is, the wear-resistant rubber strips 9 support the coating layer 1, and the perforations 10 inside the wear-resistant rubber strips 9 meet the elastic deformation of the wear-resistant rubber strips 9, thereby meeting the buffering of the entire wire body when it falls on the ground; and multiple wear-resistant rubber strips 9 are enclosed on the outside of the coating layer 1 to improve the tensile strength of the entire wire body against swinging.

[0033] 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.
