1 is an exploded perspective view showing a charging device 1 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a cross section of the charging device 1 of FIG. 1.

Referring to FIGS. 1 and 2, the charging device 1 may accommodate a cable assembly 100 for charging therein. The charging device 1 may include a charging unit 10, a main case 15, a storage case 20, and a cable assembly 100.

The charging device 1 may supply power to a battery device (not shown) by being connected to a battery in which the cable assembly 100 is installed inside the charging unit 10. In addition, the charging device 1 has a form of a charger in which the charging unit 10 is connected to an electrical outlet, and the charging unit 10 electrically connects the electrical outlet and the cable assembly 100 to power electronic devices (not shown). Can supply.

In detail, as an embodiment, the charging unit 10 may include a battery or a rechargeable battery. The charging unit 10 may be charged by receiving power from the outside through the cable assembly 100 or may supply power to other devices. For example, the charging unit 10 may be a rechargeable secondary battery and may be configured as a lithium-ion battery.

An electrode pin 11 is disposed on one side of the charging unit 10 to be connected to the electrode terminal 102 of the cable assembly 100. When the cable assembly 100 is mounted on the main case 15 while being accommodated in the storage case 20, the electrode pin 11 is electrically connected to the electrode terminal 102.

In another embodiment, although not shown in the drawings, the charging unit 10 may be a charger that inserts a pin into an electrical outlet (not shown). That is, the cable assembly 100 is assembled to the charging unit 10 and the charging unit 10 is connected to an electrical outlet (not shown) to charge an electronic device (not shown).

The main case 15 has an internal space for accommodating the charging unit 10. The main case 15 is coupled with the storage case 20 to connect the cable assembly 100 to the charging unit 10. In the drawings, the main case 15 and the storage case 20 are separated from each other, but the present invention is not limited thereto, and the main case 15 and the storage case 20 may be integrally formed.

The storage case 20 is mounted on one side of the charging unit 10 and may accommodate the cable assembly 100. The storage case 20 may have an opening to allow the cable assembly 100 to be withdrawn when the charging device 1 is used. For example, the storage case 20 includes a first housing 21 connected to the main case 15 and a second housing 22 hingedly coupled to the first housing 21 to open the storage case 20. Can be equipped.

The storage case 20 is integrally formed with the charging unit 10 or the main case 15, so that the charging unit 10, the storage case 20, and the cable assembly 100 may be formed as one device.

In addition, in another embodiment, the cable assembly 100 is integrally installed in the storage case 20, and the storage case 20 may be mounted on the charging unit 10 and used. That is, the power cable assembly having the storage case 20 may be manufactured separately from the charging unit 10.

3 is a view showing a state in which the cable assembly 100 of the charging device 1 of FIG. 2 is unfolded, and FIG. 4 is an enlarged view showing a bent end of FIG. 2.

1 to 4, the cable assembly 100 always maintains the bent end 120, but the other portion has flexibility. That is, the cable assembly 100 can be easily folded by the bent position of the bent end 120, and the user can easily extend or bend it by the flexible portion.

The cable assembly 100 may include a cable line 110, a bent end 120, and a shape maintaining member 130. A plug 101 is provided at one end of the cable line 110 and an electrode terminal 102 is provided at the other end. The cable assembly 100 may have a serpentine shape by the bent end 120.

The cable line 110 has flexibility, and an electric wire (not shown) may be disposed therein. The outside of the cable line 110 may be covered with a soft covering member. For example, the cable line 110 may be formed of a synthetic resin having polyimide-based insulating properties.

The cable line 110 has flexibility so that a user can change its position. The cable line 110 may be bent or bent.

The cable line 110 extends in one direction and may have a strip shape. Referring to Figure 1, the cable line 110 has a thin strip shape. However, the cable line 110 is not limited thereto, and may have various shapes such as a substantially cylindrical shape. However, in the following description, for convenience of description, the case of having a strip shape will be mainly described.

A plug 101 may be installed at the end of the cable line 110. The plug 101 can be applied in various ways depending on the target device to be connected.

A plurality of bent ends 120 are arranged at predetermined intervals along the cable line 110. The bent end 120 is formed by bending the cable line 110.

The preset distance between the bent ends 120 may be variously set for a shape for storage or the like. As shown in FIG. 2, the length of the cable assembly 100 arranged by the distance between the bent ends 120 may be set.

The bent end 120 is formed by bending the cable line 110 180 degrees. That is, the cable assembly 100 has a state where the cable line 110 is completely overlapped at the bent end 120, and the bent end 120 always maintains the bent state.

The bent end 120 has a predetermined rigidity to maintain the bent shape. The bent end 120 may include a portion having a flat shape and a portion having a folded shape. The bent end 120 may have a first end 121 to which the cable lines 110 are flatly attached to each other, and a second end 122 to which the cable line 110 is completely folded.

The first end 121 is formed to be flat by attaching the surface of the cable line 110 overlapped by the shape maintaining member 130. The first end 121 has a length of C1 along the shape maintaining member 130, and the bent end 120 may have a predetermined rigidity.

The second end 122 is formed by completely folding the cable line 110 and has a shape bent 180 degrees. The second end 122 has a round shape on the outside and forms a length of C2. The second stage 122 is formed by molding 180 degrees, and the shape does not change even if the user applies an additional external force thereafter.

Since the first end 121 forms a constant flat section, fatigue failure of the cable assembly 100 can be reduced. Since the second end 122 is bent by 180 degrees, a considerable stress is changed, but the first end 121 is in a state where there is no stress change.

If the first end 121 is absent or the length is very short, the boundary portion of the bent end 120 may be easily damaged when the user bends the flexible flexible area FA. However, since the first end 121 has a predetermined C1 length, the flat portion of the first end 121 has a change in stress even if the boundary portion of the bent end 120 is bent. It is possible to maintain the durability of the bent end 120 by preventing the transfer.

The first end 121 and the second end 122 of the bent end 120 always maintain a constant shape, and the shape does not change even when an additional external force is applied. Therefore, even if the user applies force to the cable assembly 100 for use and storage of the cable assembly 100, the cable assembly 100 is not fatigued by repeated bending, and durability is not reduced.

The shape maintaining member 130 may be mounted on the bent end 120 so that the bent end 120 maintains a bent shape. The shape maintaining member 130 may have the form of an adhesive layer attached to the surface of the cable line 110 folded at the bent end 120.

The shape maintaining member 130 is attached to the first end 121 of the bent end 120 to attach and fix the cable lines 110 superimposed on each other. By the shape maintaining member 130, the bent end 120 may always be folded 180 degrees.

The bent end 120 may be formed by pressing the cable line 110 with a press mechanism (not shown) after the shape maintaining member 130 is applied to the surface of the cable line 110.

In addition, in another embodiment, a part of the adhesive layer is formed to be inserted into the surface of the cable line, so that the thickness of the bent end may be formed to be thinner and flatter.

The cable assembly 100 may be divided into a flexible area FA and a bent area CA by the bent end 120. The bent area CA is defined as a section corresponding to the bent end 120. The flexible area FA is defined as an area between the bent ends 120 and is flexible by the cable line 110.

The position or shape of the flexible area FA may be changed by a user. When storing the cable assembly 100, it has a folded arrangement as shown in FIG. 2, but when the cable assembly 100 is used, the flexible area FA as shown in FIG. 3 extends or bends the cable assembly 100 It can be used in various ways.

Since the bent end 120 maintains a constant bent shape by the shape maintaining member 130, the bent area CA has a predetermined rigidity. As shown in FIG. 3, the shape of the flexible area FA may be changed, but the bending area CA maintains a constant bending shape. Since the bent end 120 is not bent, it is possible to prevent the bent end 120 from being damaged by fatigue stress.

Since the cable assembly 100 has a distance L between the bent ends 120, the user can easily arrange and receive the cable assembly 100. By setting the cable assembly 100 overlapped in FIG. 2 to have a length of L, the user can easily arrange the cable assembly 100. In addition, since they are stacked in a certain shape, they can be easily stored in the storage space.

In the conventional charging device, the charging unit and the cable assembly are stored separately, and the cable is attached to the charging unit when using. Since the cable assembly must be separated and stored, the risk of loss is high, and electrical connection failure between the cable assembly and the charging unit may occur due to repeated use.

In particular, the cable assembly was used by the user bending the cable according to the use. However, if the user continuously bends a specific part, it is liable to be damaged by fatigue stress. In addition, in the conventional cable assembly, in order to store it in a storage space, it is common to be arbitrarily wrinkled and stored, and at this time, damage such as tangling of the cable assembly may occur.

The cable assembly 100 mounted on the charging device 1 is not changed in shape after a shape that is bent in advance at the bent end 120 is formed, so that durability may be improved. When the bending end 120 is bent 180 degrees, the shape does not change due to an external force thereafter. In the bent end 120, a stress change occurs during the initial bending molding by 180 degrees, but since the stress does not change due to the bending of the cable assembly 100 thereafter, the cable assembly ( 100) is not damaged.

In addition, even if the user applies an external force to the flexible region FA to bend the cable line 110, the degree of bending is not large, and thus it is not easily damaged due to fatigue accumulation. In detail, the cable line 110 may be bent about θ as shown in FIG. 4 to extend long. However, since the bending angle is large, even if repeatedly used, the connection portion between the bent end 120 and the cable line 110 is not easily damaged.

That is, the cable assembly 100 maintaining the bent shape according to the present invention forms a large stress strain in advance at the bent end 120, but does not cause any more stress change by fixing the shape at the bent end 120. By doing so, it is possible to maintain the durability of the bent end 120.

In addition, even if the cable line 110 at the boundary of the bent end 120 is bent, the degree of bending between the bent end 120 and the cable line 110 is small, so that it is not damaged due to fatigue accumulation, thus increasing the durability of the cable assembly 100. Can be maintained.

The charging device 1 according to the present invention can be easily accommodated because a certain shape can be set by the bent end 120 of the cable assembly 100. In addition, when the user uses the cable assembly 100, the flexible area FA can be modified and used in various ways, and when the cable assembly 100 is stored, the bent ends 120 are arranged so as to overlap to achieve a certain standard. It can be easily stored by having it.

5A to 5D are enlarged views illustrating a modified example of the bent end 120 shown in FIG. 4.

Referring to FIG. 5A, the bent end 120 may include a magnet 140. The magnet 140 may be installed on one side of the bent end 120 to attach adjacent bent ends.

The magnet 140 may be applied to the outer surface of the bent end 120. The magnet 140 may be applied to the flat first end of the bent end 120. The magnet 140 is not limited to a specific shape, and may be applied in various forms to form an attractive force by providing a magnetic material.

When the magnet 140 is applied to each of the plurality of bent ends 120, the plurality of bent ends 120 are attached to each other by the attractive force of the magnet 140. The cable assembly 100 is easy to store because the bent ends 120 are attached to each other so that the arrangement as shown in FIG. 2 can be easily formed. In addition, the cable assembly 100 is not disorganized due to the attractive force acting on the bent end 120 even during storage.

Referring to FIG. 5B, the magnet 140a may be disposed between the bent ends 120. The magnet 140a may attach adjacent bent ends to each other. Since the magnet 140a is not exposed to the outside of the cable assembly 100, degeneration and damage due to an external environment can be prevented.

At least a portion of the magnet 140a may be disposed between the shape maintaining members 130. Since a part of the magnet 140a is in contact with the adhesive layer, it is possible to prevent the magnet 140a from being separated from the outside.

Referring to FIG. 5C, the magnet 140b may be disposed at the end of the bent end 120. The magnet 140b is disposed at the end of the bent end 120 so that neighboring bent ends can be attached to each other. Since the ends of the cable assembly 100 in which the magnets 140b are superimposed are aligned, the bent end 120 can be easily attached at the same time as the alignment.

Referring to FIG. 5D, a contact member 150 in contact with the magnet 140 may be further included. The contact member 150 may be disposed on the other side of the bent end 120 to be attached to a magnet disposed on one side of the adjacent bent end.

The contact member 150 reinforces the attractive force of the magnet 140 so that the cable assembly 100 can be easily set in a stacked arrangement, thereby improving storage and mobility of the cable assembly 100.

6 is a perspective view showing a part of a cable assembly 200 according to another embodiment of the present invention.

Referring to FIG. 6, the bent end 120 of the cable assembly 200 may maintain a bent shape by the shape maintaining member 230. The shape maintaining member 230 may be formed as a cover into which the bent end 120 is inserted. The cover may support at least one side of the bent end 120 to maintain the shape of the bent end 120.

When the bent end 120 is inserted into the cover, the bent shape of the bent end 120 may be kept constant. That is, even if the user uses the cable assembly 200, since the bent end 120 is inserted into the cover, the bent shape is maintained.

6 illustrates that the cover closes the lower portion of the bent end 640, but is not limited thereto, and an embodiment in which the lower portion of the bent end 120 is opened may also be included.

Since the cable assembly 200 maintaining the bent shape according to the present invention continuously maintains the bent shape at the bent end 120, the durability of the bent end 120 can be kept constant.

In addition, since a certain shape can be set by the bent end 120, it can be easily accommodated. When using the cable assembly 200, the flexible area (FA) can be used in various ways, and when storing the cable assembly 200, the folded cable can have a certain standard by arranging the covers to overlap each other. Therefore, the cable assembly 200 can be easily stored.

7 is a perspective view showing a part of a cable assembly 300 according to another embodiment of the present invention.

Referring to FIG. 7, the bent end 120 of the cable assembly 300 may maintain a bent shape by the shape maintaining member 330. The shape maintaining member 330 may be formed as a band surrounding the outside of the bent end 120.

The band surrounds the outside of the bent end 120, so that the bent end 120 can maintain a bent shape. That is, even if the user uses the cable assembly 300, the bent end 120 can be uniformly maintained by the band.

Since the cable assembly 300 maintaining the bent shape according to the present invention continuously maintains the bent shape at the bent end 120, the durability of the bent end 120 can be kept constant.

In addition, since a certain shape can be set by the bent end 120, it can be easily accommodated. When the cable assembly 300 is used, the flexible area (FA) can be used in various ways, and when storing the cable assembly 300, the bands are arranged to overlap each other so that the folded cable has a certain standard. Therefore, the cable assembly 300 can be easily stored.

Power can be supplied.

The cable assembly 400 may maintain a folded shape by connecting a plurality of cable lines 410 by a connector 430. The cable assembly 400 maintaining the folded shape may include a plurality of cable lines 410, connection terminals 420, and connectors 430. A plug 401 is provided at one end of the cable line 410 and an electrode terminal 402 is provided at the other end. The cable assembly 400 may have a serpentine shape by the connector 430.

A plurality of cable lines 410 may be provided to form each section of the cable assembly 400. Since the cable assembly 400 is segmented into the cable line 410, the length of the cable assembly 400 may be adjusted by connecting the cable line 410.

The length of each cable line 410 is not limited to a specific length, and may be variously set according to a purpose and function of use. However, in the following description, for convenience of description, the case where each cable line 410 has a length of L as shown in FIG. 9A will be described.

The cable line 410 may extend in one direction. 8, the cable line 410 has a substantially cylindrical shape. However, the cable line 410 is not limited thereto, and may have various shapes such as a thin strip shape.

A plug 401 may be installed at the end of the cable line 410. The terminals may be applied in various ways according to the purpose of use of the cable assembly 400.

In FIG. 8, the connection terminal 420 is illustrated to have a pin shape, but is not limited thereto and may be formed in various shapes capable of electrical connection.

The connector 430 may electrically connect the cable line 410. The connector 430 may include a body 431 and a connection opening into which the connection terminal 420 is inserted. Since the connection opening is disposed on one side of the connector 430, adjacent cable lines 410 may be disposed in parallel with each other.

In detail, the connector 430 includes a first connection opening 432 and a second connection opening 433 on one side of the body 431. A connection terminal 420 of one cable line is inserted into the first connection opening 432, and a connection terminal 420 of another adjacent cable line is inserted into the second connection opening 433. Since the first connection opening 432 and the second connection opening 433 are formed on the same side, the two cable lines may be disposed to overlap each other.

The cable assembly 400 may be divided into a flexible area FA and a rigid area RA by the connector 430. The rigid area RA is defined as a section corresponding to the connector 430 and has rigidity by the connector 430. The flexible area FA is defined as an area between the connectors 430 and is flexible by the cable line 410.
