[0077] The fastening member (230) may include a fixing groove (231) through which a protrusion (223) of the cable ring (220) passes. Multiple fixing grooves (231) may be formed. That is, the fastening member (230) can be fixed to the cable ring (220) by the protrusion (223) passing through the fixing groove (231). More specifically, the fastening member (230) can be fixed to the outer surface of the cable ring (220) and simultaneously wound into the receiving groove (221) of the cable ring (220) by the protrusion (223) passing through the fixing groove (231). Accordingly, the fastening member (230) shown in FIGS. 4 and 5 can be wound into the receiving groove (221) of the cable ring (220) together with the wire (210) shown in FIG. 2, which is not shown in FIGS. 4 and 5.

[0078] Referring to FIG. 5, the cable loop (220) can be tightened by a fastening member (230) so that at least a portion of its inner surface meets the charging cable (10). More specifically, the first cable loop (2201) and the second cable loop (2202) can each be tightened by the fastening member (230) so that at least a portion of their inner surface meets the charging cable (10).

[0090] A hard pad may be formed on the inner surface of the fastening member (240). That is, the cable loop (220) may be compressed by the hard pad formed on the inner surface of the fastening member (240), so that as a result, at least a portion of the inner surface of the cable loop (220) may be tightened to meet the charging cable (10). More specifically, the first cable loop (2201) may be compressed by the hard pad formed on the inner surface of the first fastening member (2401), so that as a result, at least a portion of the inner surface of the first cable loop (2201) may be tightened to meet the charging cable (10). Additionally, the second cable loop (2202) may be compressed by the hard pad formed on the inner surface of the second fastening member (2402), so that as a result, at least a portion of the inner surface of the second cable loop (2202) may be tightened to meet the charging cable (10).

[0091] As described above, the inner surface of the cable loop (220) may be formed with a diameter larger than the diameter of the charging cable (10). More specifically, the cable loop (220) wraps around the charging cable (10) while being tightened by the fastening member (240), so the diameter of the inner surface of the cable loop (220) may be formed larger than the diameter of the charging cable (10).

[0092] Accordingly, the connecting device (200) according to the embodiments has the effect of being more convenient in manufacturing the cable loop (220) because the cable loop (220) is tightened by the fastening member (240) while simultaneously wrapping the charging cable (10), so the diameter of the inner circumference of the cable loop (220) does not need to be the same as the diameter of the charging cable (10).

[0093] In addition, the connecting device (200) according to the embodiments has the effect that the inner diameter of the cable loop (220) is larger than the diameter of the charging cable (10), so the cable loop (220) can be used universally regardless of the size of the charging cable (10).

[0097] The cover bracket (250) may include a first cover bracket (2501) and a second cover bracket (2502) formed in a mutually connectable structure. The first cover bracket (2501) and the second cover bracket (2502) can be connected to each other by fastening bolts at the top and at the bottom.

[0098] The cover bracket (250) may include a locking portion (2511, 2512) formed on an upper end of one end and fixed by being caught on a stepped portion (2441, 2442) formed on the outer surface (2431, 2432) of the fastening member (240). More specifically, the first cover bracket (2501) may include a first locking portion (2511) formed on an upper end of one end and fixed by being caught on a first stepped portion (2441) formed on the edge forming the outer surface (2431) of the first fastening member (2401). Additionally, the second cover bracket (2502) may include a second locking portion (2512) formed on an upper end of one end and fixed by being caught on a second stepped portion (2442) formed on the edge forming the outer surface (2432) of the second fastening member (2402).

[0099] That is, the cover bracket (250) can be prevented from moving in a specific direction by being fixed at one end to the fastening member (240).

[0100] Additionally, one lower end of the cover bracket (250) may be rotatably connected to the lower end of the fastening member (240). More specifically, one lower end of the first cover bracket (2501) may be rotatably connected to the lower end of the first fastening member (2401), and one lower end of the second cover bracket (2502) may be rotatably connected to the lower end of the second fastening member (2402). For example, one lower end of the cover bracket (250) may be connected to the lower end of the fastening member (240) by a hinge connection.

[0101] That is, the cover bracket (250) has a lower portion that is rotatably coupled to the lower portion of the fastening member (240), so that the cover bracket (250) can rotate relative to the lower portion of the fastening member (240).

[0102] Referring to FIG. 11, the cover bracket (250) can be hinge-coupled at one end of the lower portion of the fastening member (240). That is, the cover bracket (250) can rotate relative to the lower portion of the fastening member (240). More specifically, the cover bracket (250) that encloses the charging cable (10) can rotate to form a curvature equal to the curvature formed by the charging cable (10) due to the weight of the charging cable (10). For example, as shown in FIG. 11, the cover bracket (250) positioned to the left relative to the fastening member (240) can rotate counterclockwise due to gravity caused by the weight of the charging cable (10). Alternatively, for example, the cover bracket (250) positioned to the right relative to the fastening member (240) can rotate clockwise due to gravity caused by the weight of the charging cable (10).

[0103] That is, the cover bracket (250) can rotate its upper portion counterclockwise or clockwise relative to the lower portion of the fastening member (240). At this time, the counterclockwise or clockwise rotation of the cover bracket (250) can be stopped at a certain point by the fastening member (240). More specifically, when the cover bracket (250) rotates counterclockwise or clockwise, the catch portion (251) formed on the upper portion of one end of the cover bracket (250) can engage with the stepped portion (244) formed on the outer surface (243) of the fastening member (240). That is, by the catch portion (251) of the cover bracket (250) engaging with the stepped portion (244) of the fastening member (240), the cover bracket (250) can no longer rotate.

[0104] Accordingly, the connecting device (200) according to the embodiments has the effect of allowing the charging cable (10) to maintain a natural curvature due to gravity. That is, when the charging cable (10) naturally sags due to gravity, the cover bracket (250) surrounding the charging cable (10) can rotate naturally together with the charging cable (10).

[0105] Additionally, the cover bracket (250) may include a fixing rib (252) formed at the other end protruding toward the charging cable (10). More specifically, the first cover bracket (2501) may include a first fixing rib (2521) formed at the other end protruding toward the charging cable (10). Additionally, the second cover bracket (2502) may include a second fixing rib (2522) formed at the other end protruding toward the charging cable (10). At this time, the other end of the cover bracket (250) may be positioned opposite to the position where the fastening member (240) is formed. That is, one end of the cover bracket (250) may be formed in the direction where the fastening member (240) is formed, and the other end of the cover bracket (250) may be formed in the direction opposite to the side where the fastening member (240) is formed.

[0106] The fixed rib (252) can be formed at the lower end of the other end of the cover bracket (250). That is, the fixed rib (252) can meet the lower part of the charging cable (10). By meeting the lower part of the charging cable (10), the fixed rib (252) can prevent the charging cable (10) from moving due to gravity. That is, the fixed rib (252) can prevent the charging cable (10) from being pushed further.

[0107] Below, the fixed rib (252) will be described in detail.

[0108] FIG. 12 is a drawing showing a cover bracket (250) of a connecting device (200) according to embodiments. More specifically, FIG. 12 shows embodiments of a fixing rib (252) formed at the other end of the cover bracket (250).

In other words, the fixing rib (252) may be formed with its upper surface inclined, and at the same time, its upper surface may be formed inclined toward the downward direction from the other end.

[0111] Alternatively, referring to (c) of FIG. 12, the fixed rib (252) may be formed in a shape in which a concave groove (253) is formed in the upper surface. In other words, the fixed rib (252) may be formed such that the other end and the end forming the upper surface are spaced apart from each other by forming a concave groove (253) on the upper surface.

[0112] Alternatively, referring to FIG. 12 (d), the cover bracket (250) may further include a blocking member (254) in which one side meets the charging cable (10) and the other side meets the upper surface of the fixing rib (252). In other words, the blocking member (254) may be formed between the fixing rib (252) and the charging cable (10). At this time, the shape of the fixing rib (252) may correspond to the shape of the fixing rib (252) shown in FIG. 12 (a) as shown in FIG. 12 (d), or it may correspond to the shape of the fixing rib (252) shown in FIG. 12 (b) or FIG. 12 (c) as shown in FIG. 12 (d).

[0113] The anti-slip member (254) can be formed in a shape that wraps around the fixed rib (252), as shown in (d) of FIG. 12. That is, the other side of the anti-slip member (254) can be formed in a 'C' shape to wrap around the upper surface and side of the fixed rib (252). The anti-slip member (254) may correspond to a member having an anti-slip function to prevent the charging cable (10) from slipping, and may correspond to a type of non-slip pad. For example, the anti-slip member (254) may be made of rubber.

[0118] Referring to FIG. 14, both the left cover bracket (250-1) and the right cover bracket (250-2) can be hinge-connected to the lower portion of the fastening member (240). That is, one lower portion of the left cover bracket (250-1) can be rotatably connected to the lower portion of the fastening member (240). Additionally, one lower portion of the right cover bracket (250-2) can be rotatably connected to the lower portion of the fastening member (240).

[0119] The left cover bracket (250-1) can rotate counterclockwise due to gravity caused by the weight of the charging cable (10). Additionally, the right cover bracket (250-2) can rotate clockwise due to gravity caused by the weight of the charging cable (10).

[0120] Accordingly, the connecting device (200) according to the embodiments has the effect of allowing the charging cable (10) to maintain a natural curvature due to gravity. That is, when the charging cable (10) naturally sags due to gravity, the cover bracket (250) surrounding the charging cable (10) can rotate naturally together with the charging cable (10).
