Fig. 1 is an exploded perspective view of a cable assembly 100 that maintains a folded shape according to one embodiment of the present invention. Fig. 2A is a diagram showing the cable assembly 100 of fig. 1 in a folded state, and fig. 2B is a diagram showing the cable assembly 100 of fig. 2A in an unfolded state.

Referring to fig. 1 to 2B, a plurality of cable wires 110 are connected to each other by a connector 130 to maintain the cable assembly 100 in a folded shape. Cable assembly 100, which maintains a folded shape, may include a plurality of cable wires 100, connection terminals 120, and connectors 130.

The cable assembly 100 may be variously applied 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 device for supplying power.

The cable line 110 may have flexibility and be provided with an electric wire inside. The exterior of the cable 110 may be covered with a soft jacket material. For example, the cable wires 110 may be formed of polyimide-based synthetic resin having insulation properties.

Cable 100 is flexible so that a user can change its position. Cable 110 may be bent or curved.

A plurality of electrical cables 110 may be provided to form each portion of cable assembly 100. Since cable assembly 100 is segmented into a plurality of cable wires 110, the length of cable assembly 100 may be adjusted by adjusting the number of connected cable wires 110. The number of the cable wires 110 is shown as 5 in fig. 1 (n1, n2, n3, n4, and n5), but is not limited thereto, and may be set according to the length of the cable assembly 100 used.

The length of each cable wire 110 is not limited to any particular length, and can be variously set according to the purpose of use and function. However, hereinafter, for convenience of explanation, as shown in fig. 2A, each of the cable lines 110 has a length L as an example for emphasis on detailed description.

The cable wires 110 may extend in one direction. Referring to fig. 1, the cable wires 110 have a generally cylindrical shape. However, the electric cable 110 is not limited thereto, and may have various shapes, such as a thin strip shape.

The tail end of the cable line 110 may be provided with a terminal. The terminal may be variously applied according to the purpose of use of the cable assembly 100. For example, various accessories such as a USB terminal, an earphone terminal, and an AUX terminal may be provided.

Connection terminals 120 may be provided at both ends of each cable line 110. The connection terminal 120 may be inserted into the connector 130. The connection terminal 120 is illustrated in fig. 1 as a cylindrical shape, but is not limited thereto, and may be formed in various shapes capable of electrical connection.

The connector 130 may electrically connect the cable wires 110. The connector 130 may have a body 131 and a connection opening 133 into which the connection terminal is inserted. Since the connection opening is provided at one side of the connector 130, the adjacent electric cables 110 may be arranged side by side with each other. The cable assembly 100 may have a snake-like curled (coiled) shape through the connector 130.

Specifically, the connector 130 is provided with a first connection opening 132 and a second connection opening 133 at one side of the body 131. The connection terminal 120 of one of the electric cable lines 110 is inserted into the first connection opening 132, and the connection terminal 120 of the adjacent other electric cable line 110 is inserted into the second connection opening 133. Since the first connection opening 132 and the second connection opening 133 are formed at the same side, the two electric cables 110 may be disposed to overlap each other.

The cable assembly 100 may be divided into a flexible region FA and a rigid region RA by the connector 130. The rigid region RA is defined as a section corresponding to the connector 130, and has rigidity by the connector 130. The flexible area FA is defined as the area between the connectors 130 and is flexible by the cable wires 110.

The position and shape of the flexible area FA can be changed by the user. When storing the cable assembly 100, which has a folded arrangement as shown in fig. 2A, when using the cable assembly 100, the cable assembly 100 can be used in various ways by unfolding the cable assembly 100 or bending the flexible area FA as shown in fig. 2B.

The rigid region RA may have rigidity by the connector 130. As shown in fig. 2B, the shape of the flexible area FA may be changed, but the rigid area RA maintains a certain shape due to the rigidity of the connector 130.

Since the cable assembly 100 is formed such that the distance between the connectors 130 is the predetermined distance L, the user can easily arrange and store the cable assembly 100. In fig. 2A, by providing the overlapped cable assembly 100 to have a length L, a user can easily arrange the cable assembly 100. In addition, since the cable assemblies 100 are overlapped in a certain shape, they can be easily received in the storage space.

The user bends the cable according to the use to use the existing flexible cable assembly. However, if a user continuously bends a specific portion, the cable may be damaged due to fatigue stress. In addition, the existing cables are generally randomly bent to be stored in the storage space, and at this time, damage such as entanglement of the cables may occur.

Cable assembly 100 is improved in retention and storage. First, because each cable wire 110 may be stored separately, each cable wire 110 may be separated from connector 130 for retention and storage when cable assembly 100 is not being used by a user.

In addition, even if the electric cables 110 are stored in a state of being connected to the connector 130, they can be easily arranged and stored. Since the connectors 130 set the folding regions of the electric cables 110, when the adjacent electric cables 110 are disposed side by side with each other, the electric cables 110 can be arranged between the two connectors 130. Since the cable assembly 100 can be easily formed in an aligned state, the retention of storage can be improved.

Since the connection terminals 120 of the adjacent cable lines 110 are respectively inserted into the first connection opening 132 and the second connection opening 133, the folded shape is often maintained when the cable assembly 100 is used. Since the connector 130 is previously formed in a folded shape, the cable assembly 100 can be prevented from being damaged due to repeated bending. That is, the folded portion of the cable assembly 100 folded by the connector 130 is previously formed, and thus, additional bending when the cable assembly 100 is used and stored may be reduced.

Specifically, even when the cable assembly 100 is used, the durability can be prevented from being lowered by bending. Even if the user applies an external force to the flexible area FA to bend the electric cable 110, since the degree of bending is not large, it is not easily broken due to accumulation of fatigue. Although a force is applied to cable wires 110 to spread cable wires 110 to use cable assembly 100 as shown in fig. 2B, the portion where cable wires 110 and connector 130 are connected does not have a large bending angle. Even if the cable assembly 100 is spread in a row, the portion where the cable wires 110 and the connector 130 are connected is not bent more than 180 degrees. Therefore, even if the cable assembly 100 is repeatedly used, since a large stress variation is not formed in the connection portion of the cable wires 110 and the connector 130, the cable wires 110 are not easily damaged even if the cable assembly 100 is repeatedly used.

Since the cable assembly 100 maintaining the folded shape according to the present invention maintains the two cable lines 110 in the connector 130 in the folded shape, the cable lines 110 can be easily arranged through the connector 130 when stored, and can be prevented from being bent. In addition, excessive stress variation of the connection portion between the cable 110 and the connector 130 can be prevented at the time of use, and breakage due to accumulation of fatigue can be prevented.

The cable assembly 100 maintaining the folded shape according to the present invention may be set to a certain shape by the connector 130 and may be easily accommodated. In addition, when the user uses the cable assembly 100, the flexible area FA may be deformed to be used in various ways, and when storing the cable assembly 100, it may be provided to overlap the connectors 130 to have a certain specification for easy storage.

Fig. 3A is a diagram illustrating a cable assembly 200 maintaining a folded shape according to another embodiment of the present invention, and fig. 3B is a diagram illustrating the cable assembly 200 of fig. 3A in an unfolded state.

Referring to fig. 3A and 3B, a plurality of cable wires 210 are linked by contact terminals 220 to maintain the folded shape of the cable assembly 200. The cable assembly 200 maintaining the folded shape may include a plurality of flexible cable wires 210 and a contact end 220 having a first connection terminal 221 and a second connection terminal 222.

The first connection terminal 221 is provided at one end of the electric cable 210, and has a first contact terminal 221A. Second connection terminal 222 is provided at the other end of cable line 210, and has second contact terminal 222A.

The first contact terminal 221A of the first connection terminal 221 and the second contact terminal 222A of the second connection terminal 222 can be connected electrically. The first connection terminal 221 and the second connection terminal 222 are connected to each other so that the cable lines 210 adjacent to each other can overlap in one direction.

The cable assembly 200 may be divided into a flexible area FA and a rigid area RA by the contact end 220. The rigid area RA is defined as an area corresponding to the contact terminal 220 and has rigidity through the contact terminal 220. The flexible area FA is defined as an area between the contact terminals 220 and has flexibility by the electric cable line 110.

The cable assembly 200 is improved in terms of retention and storage. First, because each cord 210 may be stored separately, each cord 210 may be separated for retention and storage when the user is not using cable assembly 200.

Since cable assembly 200 can continuously connect cable wires 210 to adjust the length, it can be applied to various use environments.

In addition, even if cable lines 210 are stored in a state of being connected to each other, they can be easily arranged and stored. The first connection terminal 221 and the second connection terminal 222 are connected to set a folding area of the cable assembly 200. By disposing the electric cables 210 adjacent to each other, the electric cables 210 can be arranged between the contact terminals 220 on both sides. Since the cable assemblies 200 can be easily formed in an aligned state, the retention storage property of the cable assemblies 200 can be improved.

Since the first connection terminal 221 and the second connection terminal 222 are formed in a folded shape in advance, the cable assembly 200 can be prevented from being damaged due to repeated bending. That is, the folded portion of the cable assembly 200 folded by the contact terminals 220 is previously formed, and thus, additional bending may be reduced when the cable assembly 200 is used and stored.

Specifically, even when the cable assembly 200 is used, the durability can be prevented from being lowered by bending. Even if the user applies an external force to the flexible area FA to bend the cable lines 210, since the degree of bending is not large, it is not easily broken due to accumulation of fatigue. Although a force is applied to cable wires 210 to unfold cable assembly 200 as shown in fig. 3B, the portion where cable wires 210 and contact terminals 220 are connected does not have a large bending angle. Even if the cable assembly 200 is spread in a row, the portion where the cable wires 210 and the contact terminals 220 are connected is not bent more than 180 degrees. Therefore, even if the cable assembly 200 is repeatedly used, since a large stress variation is not formed in the connection portion of the cable wires 210 and the contact terminals 220, the cable assembly 200 is not easily damaged even if it is repeatedly used.

Since the cable assembly 200 maintaining the folded shape according to the present invention maintains the two cable lines 210 in the contact terminals 220 in the folded shape, the cable lines 210 can be easily arranged by the contact terminals 220 in storage, and can be prevented from being bent. In addition, excessive stress variation of the connection portion between the electric cable 210 and the contact terminal 220 can be prevented in use, and breakage due to fatigue accumulation can be prevented.

The cable assembly 200 maintaining the folded shape according to the present invention may be set to a certain shape by the contact end 220 and may be easily stored. In addition, when the user uses the cable assembly 200, the flexible area FA may be deformed to be used in various ways, and when storing the cable assembly 200, it may be provided that the contact terminals 220 overlap to have a certain specification and be easily stored.

Referring to fig. 3C, a magnet may be attached to the connection terminal to easily connect the cable line 210. The first connection terminal and the second connection terminal may be formed to be substantially the same, and hereinafter, for convenience of explanation, the first connection terminal 221' is exemplified to emphasize a detailed description.

The first connection terminal 221' may have a first contact terminal 221a and a magnet unit 221 b. The first contact terminal 221a may be connected to a second contact terminal of the second connection terminal to be electrically connected. The magnet unit 221b forms an attractive force between the first connection terminal 221' and the second connection terminal, so that the two cable lines 210 can be connected quickly and accurately.

The magnet unit 221b is shown in fig. 3C to be disposed between the first connection terminals 221a, but is not limited thereto, and may be variously changed. For example, the magnet unit 221b may be disposed at an edge of the first connection terminal 221 ', or may be disposed at the center of the first connection terminal 221'. In addition, the magnet unit 221b may be disposed at a side surface or a rear surface of the first connection terminal 221' such that an attractive force is formed on the adjacent connection terminal.

Referring to fig. 3D, the contact end 220a may have a sliding guide 223 provided to one of the first connection terminal 221 and the second connection terminal 222. The slide guide 223 may have a side wall 223a supported by the connection terminal and a guide 223b bent from the side wall 223 a.

When the slide guide 223 is provided to the first connection terminal 221, the first connection terminal 221 and the second connection terminal 222 may be electrically connected by inserting the second connection terminal 222 into the slide guide 223.

In another embodiment, as shown in fig. 3C, the first connection terminal and the second connection terminal may have the magnet unit 221b and be easily and accurately connected by a sliding guide.

Fig. 4A is a diagram illustrating a cable assembly 300 maintaining a folded shape according to another embodiment of the present invention, fig. 4B is a diagram illustrating a cable assembly 2300 of fig. 4A in an unfolded state, and fig. 5 is an enlarged view illustrating a bent portion 340 of fig. 4A.

Referring to fig. 4A to 5, the cable assembly 300 may have a cable wire 310, a connection terminal 320, a connector 330, a bent portion 340, and a shape retaining member 350. The cable wire 310, the connection terminal 320, and the connector 330 are substantially the same as the cable wire 110, the connection terminal 120, and the connector 130 described above, and hereinafter, detailed description is given by taking the bent portion 340 and the shape retaining member 350 as an example.

The bent portions 340 are disposed at predetermined intervals along the electric cable 310. The bent portion 340 is formed by bending the cable lines 310.

The predetermined distance between the bent portions 340 may be variously set to form a shape for housing and the like. As shown in fig. 4A, the length of cable assembly 300 collated by the distance between bends 340 may be set.

The bent portion 340 is provided to correspond to a portion where the electric cable 310 is folded and connected. That is, the bent portion 340 may be provided to correspond to the connector 330. The connector 330 and the bent portion 340 are disposed to correspond to each other so that the cable assembly 300 may have a certain shape when received.

The bend 340 is formed by bending the cable 310 180 degrees. That is, the cable assembly 300 has the cable lines 310 in a completely overlapped state at the bent portion 340, and the bent portion 340 always maintains a bent state.

The bent portion 340 has a predetermined rigidity to maintain a bent shape. The bent portion 340 may have a flat-shaped portion and a folded-shaped portion. The bend 340 may have a first end 341 where the cables 310 are attached flat to each other and a second end 342 where the cables 310 are fully folded.

The first end 341 is formed flatly by attaching the shape retaining member 350 to the surface of the overlapped electric cables 310. The first end 341 may have a length of C1 along the shape retaining member 350, and the bent portion 340 may have a predetermined rigidity (rigid).

The second end 342 is formed by completely folding the electric cable 310 and has a 180-degree bent shape. The second end 342 has a rounded shape on the outside and forms the length of C2. The second end 342 is formed by 180 degree molding and does not change in shape even if the user applies additional external force thereafter.

Since the first end 341 forms a certain flat section, fatigue damage of the cable assembly 300 may be reduced. Since the second end 342 is bent 180 degrees, it is in a state where considerable stress is changed, but the first end 341 is in a state where stress is not changed.

Without the first end 341 or with a very short length, the border portion of the flexure 340 can easily break when the user bends the flexible region FA of the chlamydia. However, since the first end 340 has a predetermined length of C1, even if the boundary portion of the bent portion 340 is bent, the flat portion of the first end 340 may prevent stress variation from being transferred to the second end 342 to maintain durability of the bent portion 340.

The first and second ends 341 and 342 of the bent portion 340 always maintain a certain shape and do not change the shape even if an additional external force is applied. Accordingly, although a user applies force to the cable assembly 300 to use and store the cable assembly 300, the cable assembly 300 is not fatigued by repeated bending, and durability is not reduced.

The shape maintaining member 350 may be mounted to the bent portion 340 to maintain the bent shape of the bent portion 340. The shape retaining member 350 may have the form of an adhesive layer that is attached to the surface of the cable line 310 folded at the bent portion 340.

The shape retaining member 350 may be attached to the first end 341 of the bent portion 340 to attach and fix the cable lines 310 overlapping each other. The bent portion 340 can be always maintained in a 180-degree folded state by the shape maintaining member 350.

After the shape retaining member 350 is applied to the surface of the electric cable 310, the bending portion 340 may be formed by pressing the electric cable 310 by a press.

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

Cable assembly 300 may be divided by bend 340 into a flex region FA and a bend region CA. The bending area CA is defined as an interval corresponding to the bending portion 340. The flexible area FA is defined as an area between the bent portions 340, and has flexibility by the electric cable lines 310.

The position and shape of the flexible area FA can be changed by the user. When storing the cable assembly 300, which has a folded arrangement as shown in fig. 4A, when using the cable assembly 300, the cable assembly 300 can be used in various ways by unfolding the cable assembly 300 or bending the flexible area FA, as shown in fig. 4B.

Since the bent area CA keeps the bent portion 340 in a certain bent shape by the shape keeping member 350, the bent portion 340 has a predetermined rigidity. The shape of the flexible area FA can be changed as shown in fig. 4B, but the curved area CA maintains a certain curved shape. Since the bent portion 340 is not bent, the bent portion 340 can be prevented from being damaged by fatigue stress.

The bending region 340 is disposed to correspond to the rigid region RA. Since the bending area CA and the rigid area RA are disposed parallel to each other, the cable assembly 300 can be collated and received at a predetermined distance L. By providing the overlapping cable assemblies 300 to have a length L, a user can easily organize the cable assemblies 300 and easily organize or store them in a storage space.

After the pre-bent shape of the bending part 340 is formed, the shape of the cable assembly 300 is not changed, so that durability can be improved. When the bent portion 340 is bent by 180 degrees, it is not changed by an external force thereafter. Although the bend 340 is subject to stress variations during 180 degree bend forming, additional stress variations at the bend 340 do not damage the cable assembly 300 since no stress variations occur thereafter due to bending of the cable assembly 300.

In addition, even if the user applies an external force to the flexible area FA to bend the cable lines 310, since the degree of bending is not large, it is not easily broken due to accumulation of fatigue. Specifically, as shown in fig. 5, cable wires 310 may be bent about θ degrees to deploy cable assembly 300. However, since the bending angle is not large, even if it is repeatedly used, the connection portion of the bending portion 340 and the cable line 310 is not easily damaged.

That is, although the cable assembly 300 according to the present invention forms a large stress deformation at the bent portion 340 in advance, the shape at the bent portion 340 is fixed so as not to cause a further stress deformation, so that the durability of the bent portion 340 can be maintained.

In addition, even if the cable lines 310 at the boundary portion of the bent portion 340 are bent, since the bent portion 340 and the cable lines 310 are bent to a small extent so as not to be damaged by fatigue accumulation, the durability of the cable assembly 300 can be maintained.

According to the present invention, the cable assembly 300 can be set to a certain shape by the bending portion 340 and can be easily stored. In addition, when the user uses the cable assembly 300, the flexible area FA may be deformed to be used in various ways, and when storing the cable assembly 300, it may be provided that the bent portions 340 overlap to have a certain specification and be easily stored.

Fig. 6A to 6F are enlarged views illustrating an example of deformation of the bent portion 340 illustrated in fig. 5.

Referring to fig. 6A, the bent portion 340 may include a magnet 360. The magnet 360 may be installed at one side of the bent portion 340 so that adjacent bent portions may be attached.

The magnet 360 may be coated on the outer side surface of the bending part 340. The magnet 360 may be coated on the flat first end 341 of the curved portion 340. The magnet 360 is not limited to a specific shape, and it may be applied in various forms having a magnetic material to form an attractive force.

When the magnets 360 are respectively coated on the plurality of bent portions 340, the plurality of bent portions 340 are attached to each other by the attractive force of the magnets 360. The cable assembly 300 can be easily formed into the arrangement shown in fig. 4A by attaching the bends 340 to one another for easy storage. In addition, even when the cable assembly 300 is stored, the attraction force can be applied to the bending portion 340 to prevent the arrangement of the cable assembly 300 from being scattered.

Referring to fig. 6B, the magnet 360A may be disposed between the bent portions 340. The magnet 360A may attach adjacent flexures to each other. Since the magnet 360A is not exposed to the outside of the cable assembly 300, it is possible to prevent the change in properties and breakage due to the external environment.

At least a portion of the magnet 360A may be disposed between the shape retention members 350. Since a portion of the magnet 360A is in contact with the adhesive layer, the magnet 360A can be prevented from being detached from the outside.

Referring to fig. 6C, a magnet 360B may be disposed at an end of the bent portion 340. The magnet 360 may be provided at the rear end of the bent portions 340 so that the adjacent bent portions 340 may be attached. Since the magnets 360 are arranged at the rear end of the overlapped cable assembly 300, they are easily attached while the bent portions 340 are arranged.

Referring to fig. 6D, a contact member 350 contacting the magnet 360 may be further included. The contact member 350 may be disposed at the other side of the bent portion 340 and attached with the magnet 360 disposed at one side of the adjacent bent portion 340.

The contact member 350 may enhance the attraction of the magnet 360 such that the cable assembly 300 may be easily disposed in a folded arrangement, which may thereby improve storage and mobility of the cable assembly 300.

Referring to fig. 6E, the bent portion 440 of the cable assembly 400 may maintain a shape bent by the shape maintaining member 450. The shape maintaining member 450 may be formed as a cover, and the bent portion 440 may be inserted into the cover. The cover may support at least one side of the bent portion 440 to maintain the shape of the bent portion 440.

The bent shape of the bent portion 440 may be maintained when the bent portion 440 is inserted into the cover. That is, even if the user uses the cable assembly 400, since the bent portion 440 is inserted into the cover, the bent shape can be continuously maintained.

Fig. 6E illustrates that the cover closes the lower portion of the bent portion 440, but is not limited thereto, and may include an embodiment in which the lower portion of the bent portion 440 is opened.

Since the cable assembly 400 continuously maintains the bent shape at the bent portion 440, the durability of the bent portion 440 may be maintained to a certain extent. In addition, the cable assembly 400 may have a certain shape through the bending part 440 and may be easily stored. When the cable assembly 400 is used, the flexible area FA can be deformed and variously used, and when the cable assembly 400 is stored, since the covers can be disposed to overlap each other so that the folded cable assembly 400 can have a certain specification, the cable assembly 400 can be easily stored.

Referring to fig. 6F, the bent portion 540 of the cable assembly 500 may maintain a shape bent by the shape maintaining member 550. The shape maintaining member 550 may be formed as a band (band) around the outside of the bent portion 540.

Since the outside of the bent part 540 is surrounded by the band, the bent part 540 may maintain a bent shape. That is, even if the user uses the cable assembly 500, the bent portion 540 may be maintained in a certain shape by the band.

Since the cable assembly 500 according to the present invention continuously maintains a curved shape at the bent portion 540, the durability of the bent portion 540 may be maintained to a certain degree. In addition, the cable assembly 500 may have a certain shape through the bending part 540 and may be easily stored. When the cable assembly 500 is used, the flexible area FA can be deformed and variously used, and when the cable assembly 500 is stored, since the tapes can be disposed to overlap each other so that the folded cable assembly 500 can have a certain specification, the cable assembly 500 can be easily stored.

Since the cable wires 610 and the contact terminals 620 are substantially the same as the cable wires 210 and the contact terminals 220 described above, and the bending portion 640 and the shape retaining member 650 are substantially the same as the bending portion 340 and the shape retaining member 350 described above, the repeated contents will be omitted and outlined.

The first contact terminal 621A of the first connection terminal 621 and the second contact terminal 622A of the second connection terminal 622 are formed in the rigid area RA. The bending area CA formed by the bending portion 640 is provided to correspond to the rigid area RA. Since the bending area CA and the rigid area RA are arranged side by side, the cable assembly 600 can be stored and arranged at a predetermined distance L. By providing the overlapping cable assemblies 600 to have a length L, a user can easily organize the cable assemblies 600 and easily organize or store them in a storage space.
