Description

Technical Field

[0001] The present invention relates to the technical field of charging cables, and in particular to a magnetically retractable charging cable body. Background Art

[0002] At present, smart wearable devices, smart home devices, vehicle navigation detection, medical equipment and consumer digital products on the market all need to be powered or charged during use. At this time, a charging cable with a charging plug is needed to ensure normal operation. The charging cable is also called a data cable.

[0003] The charging cables currently on the market are all in a fixed long strip shape with a fixed length, and cannot be extended or retracted according to the environment. As a result, during use, the cables are often too long and look messy. In some places that require space or on-site environment, such as when used in a car or when charging a mobile phone, the messy charging cables are easily touched by mistake, resulting in poor contact; or in some medical equipment, accidental touch may cause power failure, which may lead to serious medical accidents;

[0004] Or when you are traveling far away and carry a data cable to charge your digital products, the charging cable is long and cannot be stretched together. It will be tangled together when carried. If it is squeezed, the outer surface of the cable, that is, the outermost insulation skin, is easily damaged, which will lead to greater safety hazards and reduce the service life. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem in the prior art that the length is fixed and cannot be extended or retracted according to the environment, and to propose a magnetically retractable charging cable.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A magnetically-attractive retractable charging cable body comprises an inner core, wherein a first soft magnet and a second soft magnet are provided on both sides of the inner core; the outermost sides of the first soft magnet and the second soft magnet have opposite magnetic poles; and a first bend and a second bend are performed in the middle of the inner core.

[0008] Preferably, the cross section of the inner core is in the shape of an elongated strip, and the first soft magnetic body and the second soft magnetic body are arranged on two long sides.

[0009] Preferably, the outermost side of the inner core is wrapped with a protective layer.

[0010] Preferably, the protective layer is a polyester yarn woven mesh.

[0011] Preferably, the first bend and the second bend are relative bends.

[0012] Preferably, the first soft magnetic body and the second soft magnetic body are made of flexible NdFeB soft magnetic material.

[0013] Compared with the prior art, the present invention provides a magnetically retractable charging cable body, which has the following beneficial effects:

[0014] 1. When the magnetically retractable charging cable is not in use, the first bend and the second bend are used to automatically shrink the charging cable from the middle into a disc shape, thereby achieving the purpose of being retractable. In the process of shrinking, the first soft magnet and the second soft magnet on both sides are attached and attracted to avoid accidental dispersal of the disc-shaped charging cable.

[0015] 2. When using the magnetic retractable charging cable, you can directly pull the charging cable at both ends according to the required length until it is pulled to the required length, and the remaining length is still sucked together to achieve any length of extension and retraction. The length can be adjusted, thereby avoiding the problem of all being scattered and making the usage scene messy, and greatly avoiding the probability of accidental contact, ensuring the normal operation of electrical equipment;

[0016] 3. The magnetically retractable charging cable has a long strip-shaped cross-section through the inner core and a flattened design. The contact surface between the first soft magnet and the second soft magnet is larger, and the magnetic attraction performance is further enhanced, thereby preventing the disc-shaped charging cable from accidentally dispersing.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Example:

[0025] Reference Figure 1-Figure 4 A magnetically retractable charging cable body comprises an inner core 1, wherein the inner core 1 comprises an inner conductor and an outer insulating layer, and a first soft magnetic body 101 and a second soft magnetic body 102 are disposed on both sides of the inner core 1; Figure 3 The cross section of the inner core 1 is a long strip, the long strip is a rectangle, or on the basis of the rectangle, the two short sides are adjusted to arc shapes, and the first soft magnetic body 101 and the second soft magnetic body 102 are arranged on the two long sides.

[0026] The outermost sides of the first soft magnetic body 101 and the second soft magnetic body 102 have opposite magnetic poles.

[0027] like Figure 3 The outermost sides of the first soft magnetic body 101 and the second soft magnetic body 102 refer to the side away from the inner core 1 .

[0028] The middle of the inner core 1 is subjected to the first bend 201 and the second bend 202. The middle of the inner core 1 is the middle of the inner core 1 in the length direction. Figure 2 The first bend 201 and the second bend 201 are relative bends, that is, the bending directions of the first bend 201 are opposite to each other, and then a shaping process is performed.

[0029] Both ends of the inner core 1 are also connected with plugs for connecting with charging plugs and electrical equipment.

[0030] like Figure 1 When not in use, the first bend 201 and the second bend 201 can be used to make the charging cable body automatically shrink together in a disc shape from the middle, so as to achieve the purpose of expansion and contraction. In the process of shrinkage, the first soft magnetic body 101 and the second soft magnetic body 102 on both sides are attached to each other and attracted to generate a restraining force to prevent the disc-shaped charging cable body from accidentally spreading out.

[0031] The disc-shaped data cable can prevent the charging cables from being tangled together when carried outside, and the possibility of the insulation being damaged after being squeezed, thereby reducing safety hazards during use and increasing the service life.

[0032] The cross section of the inner core 1 is long and flat, so that the contact surface between the first soft magnetic body 101 and the second soft magnetic body 102 is larger, and the magnetic attraction performance is further enhanced, thereby preventing the disc-shaped charging cable from accidentally spreading out.

[0033] When in use, because the contraction starts from the middle, the two ends of the charging cable are at the outermost sides. Because, according to the required length, the charging cable at both ends can be directly pulled until it is pulled to the required length. Moreover, the remaining length is still attracted together due to the action of the first soft magnet 101 and the second soft magnet 102 in a fitted state, so as to achieve any length of extension and contraction. The length can be adjusted, thereby avoiding the problem of all being scattered and making the usage scene look messy, and greatly avoiding the probability of accidental contact, thereby ensuring the normal operation of electrical equipment.

[0034] like Figure 1 , Figure 3 , Figure 4 The outermost side of the inner core 1 is wrapped with a protective layer 103 , and the protective layer 103 completely wraps the inner core 1 , the first soft magnetic body 101 , and the second soft magnetic body 102 , thereby playing a protective role and improving the service life.

[0035] The protective layer 103 is a polyester yarn woven mesh, that is, it is woven with polyester yarn. It looks more beautiful and also has the functions of preventing breakage and abrasion.

[0036] The protective layer 103 may also be a soft plastic outer skin, directly wrapped around the outermost side.

[0037] The first soft magnetic body 101 and the second soft magnetic body 102 are made of flexible NdFeB soft magnetic material, and are magnetized to reach a state of magnetic saturation.

[0038] The materials of the first soft magnetic body 101 and the second soft magnetic body 102 are also doped with flame retardants to prevent spontaneous combustion due to overheating during high-power charging.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
