1 is a perspective view of a cable assembly 100 maintaining a bent shape according to an embodiment of the present invention, and FIG. 2 is a view showing a state in which the cable assembly 100 maintaining the bent shape of FIG. 1 is overlapped 3 is a view showing a state in which the cable assembly 100 maintaining the bent shape of FIG. 2 is unfolded.

1 to 3, the cable assembly 100 always maintains the bent end 120, but the other portions have 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.

The cable assembly 100 can be applied in various ways according to the purpose of use. For example, the cable assembly 100 may be a data cable for transmitting data, a cable connected to an earphone speaker, or the like, or a power cable connected to a power supply to supply power.

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.

Terminal 101 may be installed at the end of the cable line 110. The terminal 101 may be variously applied depending on the purpose of use of the cable assembly 100. For example, various parts may be installed such as a USB terminal, an earphone terminal, an AUX terminal, and the like.

4 is an enlarged view showing the bent end 120 of FIG. 2.

1 to 4, a plurality of bent ends 120 are disposed along a cable line 110 at predetermined intervals. 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 cable assembly 100 may have a serpentine shape by the bent end 120.

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.

Referring back to FIGS. 2 and 3, the cable assembly 100 may be divided into a flexible area FA and a rigid area CA by a bent end 120. The rigid 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.

The rigid region CA has a predetermined rigidity because the bent end 120 maintains a constant bent shape by the shape maintaining member 130. As shown in FIG. 3, the shape of the flexible area FA may be changed, but the rigid 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 flexible cable, the user bends the cable as necessary. However, if the user continuously bends a specific part, it is liable to be damaged by fatigue stress. In addition, conventional cables are generally randomly wrinkled and stored in order to store them in a storage space, and at this time, damage such as tangled cables may occur.

The cable assembly 100 maintaining the bent shape may have improved durability since the shape of the cable assembly 100 is not changed after the shape bent in advance at the bent end 120 is formed. 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 180 degree bending molding, but since the stress does not change due to the bending of the cable assembly 100 after that, the cable assembly 100 due to an additional stress change at the bent end 120 ) 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 cable assembly 100 maintaining the bent shape according to the present invention can be easily accommodated since it can set a certain shape by the bent end 120. 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.

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 120, 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 so that they overlap each other. Therefore, the cable 200 can be easily stored.
