[0002] Typically, electric vehicles (EVs) have been slow to become practical for a long time due to issues such as the heavier weight of the batteries installed in the vehicle compared to gasoline or diesel-powered vehicles and the time required to charge them. However, with the recent depletion of fossil fuels and environmental pollution, interest in EVs, which run on electric energy rather than fossil fuels, has grown, leading to active research and development in this area.
[0003] As a result, the widespread adoption of electric vehicles has increased in recent years. Electric vehicles are equipped with batteries that supply power for propulsion and store energy. Therefore, to keep an electric vehicle running, the batteries must be charged. Consequently, infrastructure for charging electric vehicles is essential, and to meet the growing demand for electric vehicles, fixed-mounted charging stations are being installed in various locations.
[0004] Here, electric vehicle charging devices are essential for building a stable charging infrastructure, ensuring electrical stability and long-term service life. This is because electric vehicle charging devices are primarily installed outdoors, such as in public buildings, parking lots in parks, highway rest areas, and apartment complexes.
[0005] In particular, for electric vehicles requiring frequent charging, the charging cable connecting the charger must be of a certain length for user convenience. Accordingly, a means of stably securing the charging cable is required.
[0006] Here, one end of the charging cable is connected to a body that supplies power to the charging cable, and the other end of the charging cable is connected to a charger that is coupled to the electric vehicle when charging the electric vehicle.
[0007] Therefore, to minimize damage to the charging cable, which has a certain length as described above, due to friction with the floor, a device is needed to secure the end of the charging cable to the main body.

[0047] FIG. 1 is a drawing illustrating a charging device (100) equipped with a connecting device (200) according to one embodiment of the present invention.
[0048] A charging device (100) according to one embodiment of the present invention may include a main body (110) that supplies power to a charging cable (10), a retractor (120) located on the upper side of the main body (110), and a connecting device (200) that connects the retractor (120) and the charging cable (10).
[0049] As described above, as the demand for electric vehicles (EVs) increases, infrastructure for charging electric vehicles is required, and charging devices (100) as shown in FIG. 1 are being installed in various locations.
[0050] In particular, in the case of electric vehicles that require frequent charging, the length of the charging cable (10) connected to the charger must be secured to a certain extent for the convenience of the user. Accordingly, a means for stably mounting the charging cable (10) is required. Here, one end of the charging cable (10) is connected to a main body (110) that supplies power to the charging cable (10), and the other end of the charging cable (10) is connected to a charger that is coupled to the electric vehicle when charging the electric vehicle.
[0051] Therefore, in order to minimize damage to the charging cable (10) of a certain length due to friction with the floor, it is necessary to place the end of the charging cable (10) on the main body (110), and for this purpose, a retractor (120) may be positioned on the upper side of the main body (110).
[0052] In addition, a charging device (100) according to one embodiment of the present invention may be equipped with a connecting device (200) that connects a retractor (120) and a charging cable (10). Through this, the charging cable (10) can be stably placed, minimizing damage to the charging cable (10), and improving the user's convenience in charging an electric vehicle. Hereinafter, the connecting device (200) equipped in the charging device (100) of the present invention will be described in more detail.
[0053] FIG. 2 is a drawing illustrating a connection device (200) according to one embodiment of the present invention. FIG. 3 is a drawing illustrating the internal structure of a connection device (200) according to one embodiment of the present invention. And FIG. 4 is an exploded view of a connection device (200) according to one embodiment of the present invention.
[0054] Referring to FIGS. 2 to 4 together, a connecting device (200) according to one embodiment of the present invention may include a wire (210), a cable loop (220), and a cover bracket (230). Here, the wire (210) is wound inside the retractor (120) described above with reference to FIG. 1, and may be pulled out and pulled in from the retractor (120). In addition, the cable loop (220) is structured to be fastened with the wire (210), and may be wrapped around the outer circumference of the charging cable (10) by passing the charging cable (10) through the cable loop.
[0055] Additionally, the cover bracket (230) can cover the charging cable (10) and the cable loop (220). And, the wire (210) can pass through the upper part of the cover bracket (230). In particular, the cable loop (220) can include a wire groove (221) formed on the outer circumference so that the wire (210) can be wound around it.
[0056] Therefore, the connecting device (200) according to one embodiment of the present invention is not a structure that simply connects the wire (210) to the covering member itself that covers the charging cable (10).
[0057] That is, the connecting device (200) according to one embodiment of the present invention connects the charging cable (10) and the wire (210) by winding the wire (210) around the wire groove (221) formed on the outer surface of the cable loop (220) that wraps the charging cable (10), and has a structure in which the wire (210) passes through while covering the charging cable (10) and the cable loop (220) through the cover bracket (230), thereby stably connecting the wire (210) and the charging cable (10).
[0058] In addition, if the wire (210) is simply connected to the cover member itself that covers the charging cable (10), the connection between the charging cable (10) and the wire (210) may be cut off when the cover member is damaged, which may cause inconvenience in use.
[0059] Accordingly, in order to solve this problem, a connection device (200) according to one embodiment of the present invention can connect a wire (210) to a cable loop (220) formed to wrap around a charging cable (10), and protect the cable loop (220) connected to the wire (210) from external force through a cover bracket (230). Therefore, there is an advantage in that the charging cable (10) and the wire (210) are connected even when the cover bracket (230) is damaged. In addition, there is an effect in that structural rigidity is secured to minimize the possibility of damage.
[0060] In addition, as illustrated in FIG. 3, in a connecting device (200) according to one embodiment of the present invention, a cable loop (220) may include a C-shaped shape with both ends spaced apart from each other. In addition, the wire (210) may include a hook (211) formed at one end, and the hook (211) may be positioned between both ends of the cable loop (220).
[0061] That is, the wire (210) can be wound around the wire groove (221) formed on the outer surface of the cable loop (220) through the hook (211) formed at one end of the wire (210) to support the charging cable (10).
[0062] In addition, the cable loop (220) may be formed in a C-shaped shape with both ends spaced apart from each other to facilitate coupling of the charging cable (10) and the cable loop (220).
[0063] In addition, since the hook (211) is positioned between the two ends of the cable loop (220) formed in a C shape, the structural stability of the wire (210) that is connected to the charging cable (10) while being wrapped around the cable loop (220) can be improved.
[0064] And the cover bracket (230) according to one embodiment of the present invention may include a mounting groove (231) formed in the center and into which a cable loop (220) is mounted. In addition, the cover bracket (230) may include a fixing groove (232) formed in the center and into which a penetrating wire (210) is positioned. Through this, the cover bracket (230) may serve to protect the charging cable (10), the cable loop (220), and the wire (210) wrapped around the cable loop (220) from external force.
[0065] In addition, in the connection device (200) according to one embodiment of the present invention, the cover bracket (230) can be bent in the same direction from the center to both sides. This is because, as described above with reference to FIGS. 1 and 2 , the connection device (200) of the present invention is positioned at the middle portion of the charging cable (10) having a certain length and is connected to the retractor (120) positioned at the upper side of the main body (110).
[0066] Accordingly, the curved shape of the cover bracket (230) described above is intended to more stably hold the charging cable (10) in consideration of the load applied to the charging cable (10). In addition, the curved shape of the cover bracket (230) can also minimize the risk of damage, such as the charging cable (10) breaking.
[0067] FIG. 5 is a drawing illustrating a first cover bracket (230a) in a connecting device (200) according to one embodiment of the present invention. FIG. 6 is a drawing illustrating a second cover bracket (230b) in a connecting device (200) according to one embodiment of the present invention. FIG. 7 is a drawing for explaining a cover bracket (230) that covers a charging cable (10) and a cable loop (220) in a connecting device (200) according to one embodiment of the present invention and through which a wire (210) passes. And FIG. 8 is a drawing illustrating a rivet fastener (233) formed at the lower portion of a cover bracket (230) in a connecting device (200) according to one embodiment of the present invention.
[0068] In a connection device (200) according to one embodiment of the present invention, the cover bracket (230) may include a first cover bracket (230a) and a second cover bracket (230b) formed in a mutually connectable structure. Referring to FIGS. 3 and 4 together, the first cover bracket (230a) and the second cover bracket (230b) can be opened and closed through the mutually connectable structure, thereby facilitating maintenance when connecting the charging cable (10) and the wire (210).
[0069] In addition, in the connection device (200) according to one embodiment of the present invention, the first cover bracket (230a) and the second cover bracket (230b) may include rivet fasteners (233) formed at the lower portion in a direction parallel to the charging cable (10). Here, the rivet fasteners (233) may include a pair of first rivet fasteners (233a) formed spaced apart from each other on the first cover bracket (230a). In addition, the rivet fasteners (233) may include a second rivet fastener (233b) formed on the second cover bracket (230b) and positioned between the pair of first rivet fasteners (233a). Additionally, the connection device (200) according to one embodiment of the present invention may further include a rivet (260) penetrating through the pair of first rivet fasteners (233a) and second rivet fasteners (233b).
[0070] Referring to FIG. 8 together, as described above, a second rivet fastener (233b) is positioned between a pair of first rivet fasteners (233a), and the strength of the fastening can be improved when the first cover bracket (230a) and the second cover bracket (230b) are mutually fastened through a rivet (260) penetrating the pair of first rivet fasteners (233a) and the second rivet fasteners (233b). In addition, a structure in which the first cover bracket (230a) and the second cover bracket (230b) can be opened and closed can be formed through the rivet (260). In addition, this can facilitate maintenance when fastening the charging cable (10) and the wire (210) as described above.
[0071] Referring to FIGS. 3 to 7 together, a connection device (200) according to one embodiment of the present invention may further include a first fixing rib (240) that is inserted into a mounting groove (231), comes into contact with a cable loop (220), and prevents movement of the cable loop (220). The first fixing rib (240) may be in close contact with the mounting groove (231) and the cable loop (220), thereby preventing movement of the cable loop (220), thereby stably supporting the charging cable (10).
[0072] In addition, the connecting device (200) according to one embodiment of the present invention may further include a second fixing rib (250) that is inserted into the fixing groove (232), comes into contact with the wire (210), and prevents movement of the wire (210). The second fixing rib (250) may be in close contact with the fixing groove (232) and the wire (210), thereby preventing movement of the wire (210), thereby allowing the charging cable (10) to be stably supported.
[0073] That is, the connection device (200) according to one embodiment of the present invention can prevent movement of the cable loop (220) and the wire (210) located inside the cover bracket (230) through the first fixing rib (240) and the second fixing rib (250), thereby ensuring that the retractor (120) and the charging cable (10) are stably connected even if the charging cable (10) moves. In addition, this can improve the convenience of use for the user when charging an electric vehicle through the charging device (100) of the present invention.
[0074] In summary, the connecting device and charging device comprising the same according to the present invention can stably connect wires and charging cables drawn in and out of a retractor. Furthermore, the cable loop for fastening the wires and charging cables and the cover bracket structure covering the cable loop ensure structural rigidity, thereby minimizing the risk of damage.
