Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings in order to enable a person skilled in the art to easily practice the present invention.

[0022] FIG. 1 is a drawing showing the structure of a reel-type cable device according to one embodiment of the present invention.

[0023] Referring to FIG. 1, a reel-type cable device according to one embodiment may be configured to include a first housing (100) and a rotating device (200).

[0024] The first housing (100) is formed in the shape of a container to accommodate a rotating device (200). Additionally, a second housing (not shown) may be included to be combined with the first housing (100) to form an internal receiving space.

[0025] A rotating device (200) is accommodated between the first housing (100) and the second housing.

[0026] The second surface of the rotating device (200) can be mutually coupled so that it contacts the first surface of the first housing (100).

[0027] Meanwhile, a rotation axis (101) extending a certain length in a vertical direction is formed at the center of the first surface of the first housing (100), and the rotation axis (101) is inserted into a hole (201) formed at the center of the rotation device (200). Through this, the rotation device (200) can rotate with respect to the rotation axis (101).

[0028] FIG. 2 is a drawing showing a first surface (Fig. 2(a)) and a second surface (Fig. 2(b)) of a first housing according to one embodiment of the present invention.

[0029] Referring to FIG. 2, the first surface of the first housing (100) is configured to include a bottom surface and a side surface extending a certain height in a vertical direction from the edge of the bottom surface. In this way, the first surface of the first housing (100) can be formed in the shape of a container to accommodate a rotating device (200).

[0030] Meanwhile, a first circuit board (102) is formed on the first surface of the first housing (100). The first circuit board (102) may be implemented with an area smaller than that corresponding to the shape of the first surface of the first housing (100), and its center may be pierced by the rotation axis (101).

[0031] A plurality of ring-shaped wires (103) may be formed on the first circuit board (102). The plurality of ring-shaped wires (103) may be formed, for example, in five numbers, each forming a closed circle and having different diameters. That is, the plurality of ring-shaped wires (103) may be formed on the first circuit board (102) with different diameters while having the same center and being spaced apart from each other.

[0032] On the second surface of the first housing (100), a plurality of connection terminals (104) are formed, each electrically connected to a plurality of ring-shaped wires (103) formed on the first circuit board (102).

[0033] Meanwhile, the plurality of connection terminals (104) are connected to wiring formed at one end of the first cable. The first cable may be a cable with, for example, a C-type jack formed at one end, and each wiring of the first cable may be connected to and fixed to the connection terminal (104).

[0034] FIG. 3 is a drawing showing a first surface (Fig. 3(a)) and a second surface (Fig. 3(b)) of a rotating device according to one embodiment of the present invention.

[0035] Referring to FIG. 3, a spiral spring (202) is formed at the center of the first surface of the rotating device (200).

[0036] The spiral spring (202) is a spring in which a thin, long strip of steel with a constant cross-section is wound in a coil shape on a plane.

[0037] The wiring of the second cable is connected to the outermost part of the spiral spring (202). The second cable may be a cable that is much longer than the first cable, and its wiring is connected to the outermost part of the spiral spring (202). The second cable may also be a cable with a C-type jack at its end, and it may be wound in a coiled form around the outer part of the spiral spring (202). When the end is pulled by an external force, the coiled cable is unwound. At this time, an elastic force is generated in the spiral spring (202), and when the external force acting on the end is removed, the second cable is wound again around the outer part of the spiral spring (202) by the elastic force.

[0038] A second circuit board (203) is formed on the second surface of the rotating device (200). Each terminal (204) formed on the second circuit board (203) is connected to the wiring of the second cable.

[0039] The terminals (104) of the first circuit board (102) described above and the terminals (204) of the second circuit board (203) are formed to correspond to each other.

[0040] Meanwhile, the second circuit board (203) is formed to surround a portion of the area around the hole (201) formed in the center of the rotating device (200), and the second circuit board (203) may include a plurality (e.g., 2) sets of connection terminals (205) on both sides based on the hole (201).

[0041] Each set of connection terminals (205) includes a plurality of connection terminals, and these plurality of connection terminals are electrically connected to the terminals (204).

[0042] A plurality of connection terminals included in a single connection terminal set (205) are formed with the same number as the terminals (204) and are arranged in a direction away from the hole (201). Additionally, each of the plurality of connection terminals included in a single connection terminal set (205) may be formed at a position corresponding to each of the plurality of ring-shaped wires (103) of the first housing (100).

[0043] Accordingly, when the second surface of the rotating device (200) and the first surface of the first housing (100) are joined together so as to come into contact, each of the plurality of connection terminals included in the connection terminal set (205) is connected to the plurality of ring-shaped wiring (103).

[0044] Since each of the multiple ring-shaped wires (103) is formed in a closed circular shape, even if the rotating device (200) rotates, the connection between each of the multiple connection terminals included in the connection terminal set (205) and each of the multiple ring-shaped wires (103) can be stably maintained.

[0045] FIG. 4 is a drawing showing the structure of an accessory including a reel-type cable according to one embodiment of the present invention.

[0046] Referring to Fig. 4, the accessory may consist of, for example, a rabbit-shaped doll.

[0047] Additionally, the accessory may be configured to include a body (401) and at least two protrusions (402).

[0048] A first inlet (H1) is formed in the body (401), and second and third inlets (H2, H3) may be formed in the two protrusions (402), respectively. Through the first to third inlets (H1~H3), a reel-type cable can be inserted into the accessory.

[0049] Through the first inlet (H1), a main body, that is, a main body in which the first housing (100) and the second housing are combined, is introduced in a reel-type cable according to one embodiment of the present invention, through the second inlet (H2), the first cable described above is introduced, and through the third inlet (H3), the second cable described above can be introduced.

[0050] The space inside the accessory communicating with these first to third inlets (H1, H2, H3) is formed integrally so that the space can be shared with each other.

[0051] If the user wishes to use the cable, the second cable inserted into the third input port (H3) can be extended by pulling it out to the outside.

[0052] In this case, the first cable inserted into the second input port (H2) is not extended together and remains fixed in place.

[0053] This is because, as explained with reference to FIGS. 1 to 3, in a reel-type cable device, the first cable is connected to a terminal of the first circuit board (102) formed in the first housing (100).

[0054] Accordingly, the cable is extended only through one protrusion (402) of the accessory, and deformation of the accessory can be minimized.

[0055] In addition, when using the cable, the accessory is positioned on only one side of the cable rather than in the middle of the long extended cable, so the aesthetic sense can be minimized.

[0056] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical spirit or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.
