[0003] When an existing laptop computer is in use, a power cord is required to power the laptop computer. During power supply, when an external force pulls the power cord, if the pulling force is too large, it exceeds the strength limit of the power cord and the power cord may break, which will cause the power cord to be interrupted, resulting in poor safety of the power cord during use. Therefore, a high-strength power cord and a storage method thereof are proposed. Summary of the invention

[0004] The object of the present invention is to provide a high-strength power cord and a storage method thereof, so as to solve the problem proposed in the above-mentioned background technology that when the external force pulls the power cord, the pulling force is too large, exceeding the strength limit of the power cord, and the power cord may break, which will cause the power cord to be interrupted, resulting in poor safety of the power cord when in use.

[0005] To achieve the above object, the present invention provides the following technical solution: a high-strength power cord, comprising a power cord body, the power cord body is electrically connected to a power adapter, one end of the power cord body is electrically connected to a first plug, the other end of the power cord body is electrically connected to a second plug, a fixing ring is fixedly sleeved on the outer side of the power cord body, and a connecting component is provided on one side of the power cord body;

[0006] The power cord body includes a plurality of wire cores, an insulating layer is sleeved on the outside of the plurality of wire cores, a metal mesh layer is sleeved on the outside of the insulating layer, a flame retardant layer is sleeved on the outside of the metal mesh layer, an outer skin layer is sleeved on the outside of the flame retardant layer, a wear-resistant layer is sleeved on the outside of the outer skin layer, and the inside of the insulating layer is filled with a sponge layer located between the wire cores.

[0016] S2, storing the power cord body, bending the excess power cord body, and then inserting the bent power cord body into the inner side of the storage cavity, after the elasticity of the rubber ring is stretched, the bent power cord body can be stored in the inner side of the storage cavity;

[0017] S3. When the power cord body is in use and is pulled by external force, the pin leaves the inner side of the socket, and the spring is compressed, the slide slides on the inner side of the slide groove, and the slide drives the locking block to leave the inner side of the lock groove.

[0035] Example

[0036] In the prior art, when an external force pulls the power cord, if the pulling force is too large, it exceeds the strength limit of the power cord and the power cord may break, which will cause the power cord to be interrupted, resulting in poor safety of the power cord during use.

[0037] See also Figure 1-6 The present invention provides a technical solution: a high-strength power cord, including a power cord body 1, the power cord body 1 is electrically connected to a power adapter 4, one end of the power cord body 1 is electrically connected to a first plug 8, one end of the first plug 8 is inserted into the inner side of an external socket, and then the alternating current is converted into direct current under the voltage transformation of the power adapter 4, and finally the second plug 10 is connected to the power socket of a notebook computer to power the notebook computer, the other end of the power cord body 1 is electrically connected to the second plug 10, the outer side of the power cord body 1 is fixedly sleeved with a fixing ring 3, the material of the fixing ring 3 is rubber, the fixing ring 3 is fixedly sleeved on the outer side of the power cord body 1, and a connecting component 2 is provided on one side of the power cord body 1;

[0038] The power cord body 1 includes a plurality of wire cores 11, the material of the wire cores 11 is metal copper, the outer sides of the plurality of wire cores 11 are sleeved with insulating layers 13, the material of the insulating layer 13 is PVC, the outer side of the insulating layer 13 is sleeved with a metal mesh layer 14, the material of the metal mesh layer 14 is steel wire, the outer side of the metal mesh layer 14 is sleeved with a flame retardant layer 15, the material of the flame retardant layer 15 is polytetrafluoroethylene, the outer side of the flame retardant layer 15 is sleeved with an outer skin layer 16, the material of the outer skin layer 16 is PVC, the outer side of the outer skin layer 16 is sleeved with a wear-resistant layer 17, the material of the wear-resistant layer 17 is wear-resistant rubber, and the inner side of the insulating layer 13 is filled with a sponge layer 12 located between the wire cores 11.

[0039] The connecting assembly 2 includes two first connecting frames 21 and two second connecting frames 22. The first connecting frames 21 are respectively provided with a slide groove 210 and a limit groove 211. A locking rod 23 is fixed to one side of the second connecting frame 22. When the power cord body 1 is pulled by an external force, the pulling force will drive the pin 24 to leave the outer side of the socket 25. When the locking rod 23 slides on the inner side of the limit groove 211, one side of the wire core 11 is electrically connected with the pin 24 and the socket 25 respectively. The outer side of the pin 24 is inserted into the inner side of the socket 25. An arc surface is provided at the matching position between the locking block 26 and the locking groove 27. Under the pulling force, the inner wall of the locking groove 27 will push the locking block 26 to move toward the inner side of the slide groove 210. A slide plate 28 is slidably connected to the inner side of the slide groove 210, and a spring 29 is connected between the top of the slide plate 28 and the inner side of the slide groove 210.

[0040] A locking block 26 is fixed on the side of the slide plate 28 away from the spring 29, and a locking groove 27 is provided on one side of the locking rod 23. The outer side of the locking block 26 is inserted into the inner side of the locking groove 27, and the slide plate 28 slides on the inner side of the slide groove 210, and at the same time, the spring 29 is compressed. At this time, the external tension causes the locking rod 23 to leave the inner side of the first connecting frame 21, and at the same time, the plug pin 24 leaves the inner side of the socket 25, so that the power cord body 1 is disconnected at the connection between the plug pin 24 and the socket 25, offsetting the external tension, and the outer side of the locking rod 23 is inserted into the inner side of the limiting groove 211. One side of the two first connecting frames 21 and the second connecting frame 22 are fixed to the outer side of the power cord body 1, so that the power cord body 1 can be quickly separated when the external tension is pulled, reducing the damage to the power cord body 1, and ensuring the safety of the power cord body 1 when in use.

[0041] A first sheath 7 is integrally formed on one side of the first plug 8 and is sleeved on the outside of the power cord body 1. A second sheath 9 is integrally formed on one side of the second plug 10 and is sleeved on the outside of the power cord body 1. The bent power cord body 1 is inserted into the inner side of the storage cavity 6 to prevent excess power cord body 1 from being randomly placed near the laptop computer. The excess power cord body 1 is stored inside the rubber ring 5. A rubber ring 5 is integrally formed on one side of the fixing ring 3, and a storage cavity 6 is provided inside the rubber ring 5.

[0042] Working principle: when the power cord body 1 is needed to power the laptop computer, first insert one end of the first plug 8 into the inner side of the external socket, then convert the AC power into DC power under the voltage transformation of the power adapter 4, and finally connect the second plug 10 to the power socket of the laptop computer to power the laptop computer. When the power cord body 1 is powered, the outer skin layer 16 is protected by the outer wear-resistant layer 17 to prevent the power cord body 1 from rubbing against external objects when the power cord body 1 is in use, causing damage to the power cord body 1. At the same time, under the action of the insulating layer 13, the wire core 11 is prevented from leaking electricity during power transmission, and under the action of the metal mesh layer 14, the tensile strength of the power cord body 1 is increased. At the same time, under the action of the flame retardant layer 15, the power cord body 1 is prevented from overheating during use.

[0043] When the power cord body 1 is supplying power to the laptop computer, the excess power cord body 1 is bent, and then the bent power cord body 1 is inserted into the storage cavity 6 to prevent the excess power cord body 1 from being randomly placed near the laptop computer. The excess power cord body 1 is stored inside the rubber ring 5, thereby improving the convenience of the power cord body 1 when in use.

[0044] When the power cord body 1 is pulled by external force, the pulling force will drive the pin 24 to leave the outer side of the socket 25. When the locking rod 23 slides inside the limiting groove 211, and the locking block 26 and the locking groove 27 are matched with an arc surface, under the pulling force, the inner wall of the locking groove 27 will push the locking block 26 to move to the inner side of the slide groove 210. At this time, the slide plate 28 slides inside the slide groove 210, and the spring 29 is compressed. At this time, the external pulling force causes the locking rod 23 to leave the inner side of the first connecting frame 21, and the pin 24 to leave the inner side of the socket 25, so that the power cord body 1 is disconnected at the connection between the pin 24 and the socket 25, and the external pulling force is offset to avoid the power cord body 1 being quickly separated when the external pulling force is pulled, thereby reducing damage to the power cord body 1 and ensuring the safety of the power cord body 1 when in use.

[0045] When the disconnected power cord body 1 needs to be connected, it is only necessary to insert the two locking rods 23 into the inner side of the limiting groove 211, then push the second connecting frame 22 to move toward the side of the first connecting frame 21, and insert the pin 24 into the inner side of the socket 25 to complete the connection of the disconnected power cord body 1.

[0046] The present invention also provides a method for storing a high-strength power cord, comprising the following steps:

[0047] S1, power connection, take out the power cord body 1 from the inside of the storage cavity 6, then connect the first plug 8 to the external power supply, and finally connect the second plug 10 to the laptop computer, and convert the AC power into DC power under the voltage transformation of the power adapter 4 to power the laptop computer;

[0048] S2, the power cord body 1 is stored, the excess power cord body 1 is bent, and then the bent power cord body 1 is inserted into the inner side of the storage cavity 6. After the elasticity of the rubber ring 5 is stretched, the bent power cord body 1 can be stored in the inner side of the storage cavity 6;

[0049] S3. When the power cord body 1 is in use and is pulled by external force, the pin 24 leaves the inner side of the socket 25, and the spring 29 is compressed, and the slide plate 28 slides on the inner side of the slide groove 210. At the same time, the slide plate 28 drives the locking block 26 to leave the inner side of the locking groove 27. At this time, under the action of external force, the locking block 26 slides through the inner side of the locking groove 27, so that the locking rod 23 slides on the inner side of the limiting groove 211 and leaves the inner side of the first connecting frame 21. At this time, the power cord body 1 is divided into two ends, namely the pin 24 section connected to the first plug 8 and the socket 25 section connected to the second plug 10.
