Description

Technical Field

[0001] The invention relates to the technical field of electronic product accessories, and in particular to a combined waterproof and dustproof data cable. Background Art

[0002] In the process of using the data cable, the USB end is connected to the charger, the charging end is connected to the mobile phone, the charger is plugged into the socket to transmit the current to the mobile phone battery through the data cable, so as to charge the mobile phone. In the process of using the data cable to charge the mobile phone, the Chinese patent with publication number CN117791222A sets a reinforcement sleeve at the end of the data cable to protect the position where the data cable is prone to breakage, thereby extending the service life of the data cable and ensuring the long-term use of the data cable. The wire part in the data cable is relatively long. During the charging process, long-term exposure will cause aging and wear of the rubber on the surface of the wire. The existing method is to set an additional layer of protective material on the surface of the wire to replace the original rubber layer in contact with the outside world. However, since the wire is relatively long as a whole, the wire is easily squeezed by objects during charging. The existing protective material only fits the surface of the wire. When squeezed by heavy objects, the force exerted on the protective material will directly act on the wire, and the pressure cannot be effectively buffered. As a result, when the line is compressed, the copper wire inside it is easily damaged, so that the data cable cannot be used normally. Summary of the invention

[0003] In order to overcome the shortcomings of the existing data cable protection method that only one layer of protective material is wrapped, the copper wire inside the data cable cannot be provided with good buffer protection when the data cable is squeezed, causing the data cable to be easily damaged, and at the same time, the use of too thick rubber protection will make the data cable difficult to store and difficult to dissipate heat, the present invention provides a combined waterproof and dustproof data cable.

[0014] Compared with the prior art, the present invention has the following advantages: the present invention realizes that the air pressure in the two corrugated covers is greater than the external air pressure. Since the air pressure in the corrugated covers is evenly distributed, the external impact force can be dispersed to the entire surface of the corrugated covers, avoiding excessive local force, thereby dispersing the pressure on the wire, and protecting the copper wire inside the wire to the greatest extent; The gas in the bellows is released by squeezing the ring, making the bellows more convenient to use; The bellows are attached to each other by magnets, and an uninflated bellows is used to reduce the space occupied by the wires, so that the bellows can be switched between conventional waterproof and dustproof and inflated protection modes according to needs; By pulling the sealing cloth to unfold it, the USB terminal and the charging terminal are completely covered and sealed, thereby preventing the USB terminal and the charging terminal from being scratched during carrying; The scraper can scrape and clean the dust attached to the surface of the wire while sliding, reducing impurities attached to the surface of the wire and extending the service life of the wire.

[0020] It also includes a pressure rod 103 and an extrusion ring 104; two pressure rods 103 are slidably connected to each baffle 4; a extrusion ring 104 is slidably connected to each retaining ring 105; a first inclined surface 10301 is provided on the side of each pressure rod 103 facing the extrusion ring 104; a plurality of second inclined surfaces 10401 are provided on the extrusion ring 104; each first inclined surface 10301 is engaged with an adjacent second inclined surface 10401.

[0021] It also includes a magnetic plug 6; the magnetic plug 6 is fixedly connected to the right side of the wire 1; a magnetic element is arranged in the magnetic plug 6; a plurality of conductive contacts 6002 are arranged on the magnetic plug 6; a slide groove 6001 is arranged in the magnetic plug 6; a plurality of contact interfaces 3002 are arranged on the charging terminal 3, and each contact interface 3002 is embedded with the adjacent conductive contact 6002; a plurality of protrusions 3001 are arranged on the charging terminal 3; each protrusion 3001 slides in the slide groove 6001.

[0022] Each shield 4 is provided with a shielding portion 4001 ; the shielding portion 4001 is attached to the connection between the wire 1 and the USB terminal 2 and the charging terminal 3 .

[0023] Each corrugated cover 5 is made of waterproof and dustproof material. After the corrugated cover 5 is unfolded, the wire 1 is protected from waterproof and dust, thereby extending the service life of the wire 1.

[0024] Each sealing cloth 101 is made of a scratch-resistant and wear-resistant material.

[0025] During use, the USB end 2 is connected to the charger, and the charging end 3 is connected to the mobile phone. The charger is plugged into the socket to transmit the current to the mobile phone battery through the wire 1, so as to charge the mobile phone. In the process of using the data cable to charge the mobile phone, the long-term exposure of the wire 1 will cause the rubber material on its surface to age and wear. The existing method is to set an additional layer of protective material on the surface of the wire 1 to replace the rubber on the surface of the wire 1 to contact the outside world. However, since the wire 1 is relatively long as a whole, the wire 1 is easily squeezed by objects during charging. The existing protective material only fits the surface of the wire 1. When it is squeezed by a heavy object, the force exerted on the protective material will directly act on the wire 1, and it cannot effectively buffer the pressure. As a result, when the wire 1 is compressed, the copper wire inside it is easily damaged, so that the data cable cannot be used normally. Therefore, in order to prevent the copper wire from being damaged, the user can pull one of the corrugated covers 5 to unfold it along the surface of the wire 1. During this process, the air cavity 5001 is continuously enlarged to form a negative pressure. Under the pressure difference on both sides of the elastic valve membrane 106, the elastic valve membrane 106 moves into the air cavity 5001 as shown in FIG. Figure 5 As shown, a gap is generated between the elastic valve membrane 106 and the retaining ring 105, so that the air cavity 5001 is no longer blocked, and the external gas enters the interior of the baffle 4 through the heat dissipation holes on the baffle 4, and then enters the air cavity 5001 through the gap between the elastic valve membrane 106 and the retaining ring 105. When the length of the bellows 5 expanded exceeds two-thirds of the length of the wire 1, the stretching of the bellows 5 is stopped, and then the user only needs to stretch the other bellows 5 in the above manner. When the length of the other bellows 5 stretched exceeds two-thirds of the length of the wire 1, the user compresses the two bellows 5 back again, so that the two bellows 5 are retracted to half the length of the wire 1 respectively. In this process, some gas will be blown out from the gap between the elastic valve membrane 106 and the retaining ring 105, and push the elastic valve membrane 106 to move back to the direction away from the air cavity 5001, and close the air cavity 5001 again. Since the bellows 5 is compressed at this time, the air pressure in the air cavity 5001 continues to increase, and the retaining ring 1 05, the elastic valve membrane 106 and the clamping ring 105 cannot move further after being fitted, and then the bellows 5 are closed under the push of air pressure and maintained in this state, so that the gas cannot be discharged, and the gas in the two bellows 5 is compressed to form an air pressure higher than the external pressure. At this time, the two bellows 5 are pressed against each other under the action of air pressure. At this time, the user only needs to loosen the bellows 5 to cover the entire wire 1, and use the waterproof and dustproof material used in the bellows 5 to protect the wire 1. At the same time, the gas filled in the bellows 5 can provide support and buffer, and evenly disperse the external impact force to the entire surface of the bellows 5 to avoid excessive local force, so that the pressure on the wire 1 is dispersed, and then the copper wire in the wire 1 is protected to the greatest extent. At the same time, the stretched bellows 5 is difficult to fold and bend at a large angle, thereby limiting the excessive bending and deformation of the wire 1, thereby avoiding excessive bending of the wire 1 and damage to the copper wire during the use of the wire 1.

[0026] Furthermore, the user can press the two pressing rods 103 to move toward each other, so that the first inclined surface 10301 moves toward the second inclined surface 10401. Figure 6 As shown, the extrusion ring 104 is pressed, and under the action of the first inclined surface 10301 squeezing the second inclined surface 10401, the extrusion ring 104 is pushed to move toward the inside of the bellows 5, so that the extrusion ring 104 pushes the elastic valve membrane 106 to move toward the air cavity 5001, and then opens the air cavity 5001, so that the gas in the air cavity 5001 is released. At this time, the user squeezes the bellows 5 to shrink it, and then puts away the bellows 5, which is more convenient in the process of using the bellows 5.

[0027] It is also considered that when the data cable is not used for charging, in order to facilitate carrying, the charger is usually unplugged from the USB terminal 2, and then the charger and the data cable are placed in a pocket or a bag. In this process, in order to prevent the USB terminal 2 and the charging terminal 3 from being scratched by sharp objects, the sealing cloth 101 is pulled to unfold it, so that the length of the sealing cloth 101 is greater than the length of the USB terminal 2 and the charging terminal 3. At this time, the user only needs to squeeze the end of the sealing cloth 101 to make the soft magnetic strips 10101 deform and then adsorb each other, so that the USB terminal 2 and the charging terminal 3 are completely covered and sealed, thereby protecting the USB terminal 2 and the charging terminal 3 from scratches when carrying. At the same time, when the charging terminal 3 is not used for a long time, the sealing cloth 101 can also be used to seal and protect it to prevent the charging terminal 3 from oxygen. It should be noted that: when the sealing cloth 101 is fully unfolded, the sealing cloth 101 is used to cover the USB terminal 2 and the charging terminal 3, and the heat dissipation holes on the shield 4 are also covered to prevent the USB terminal 2 and the charging terminal 3 from being corroded by moisture. When the sealing cloth 101 is fully retracted, the heat dissipation holes on the shield 4 are connected to the outside world. During charging, the heat dissipation holes are used to dissipate the heat of the USB terminal 2 and the charging terminal 3, so that the setting of the shield 4 does not affect the heat dissipation of the USB terminal 2 and the charging terminal 3. At the same time, a shielding portion 4001 is provided on the shield 4, and the shielding portion 4001 is used to wrap and fit the connection between the wire 1 and the USB terminal 2 and the charging terminal 3, so that excessive bending at the connection may prevent the connection from breaking, thereby further protecting the data cable.

[0028] In addition, the user can pull the charging terminal 3 to separate it from the magnetic plug 6, so that the protrusion 3001 slides out of the slide groove 6001, that is, remove the charging terminal 3, and subsequently replace and assemble charging terminals 3 of different models. By assembling charging terminals 3 of different models and types, it is possible to adapt to charging ports of different mobile phones for charging. As for locking the charging terminal 3, it is only necessary to align the protrusion 3001 with the slide groove 6001, and then insert the charging terminal 3 into the bottom of the slide groove 6001 to make the charging terminal 3 contact with the magnetic plug 6. At this time, the charging terminal 3 is adsorbed by the magnetic element provided in the magnetic plug 6, and then the contact interface 3002 is engaged with the conductive contact 6002, so that the two are in contact and form a circuit to transmit power, thereby simply completing the assembly and fixation of the charging terminal 3.

[0029] Example 2 On the basis of Example 1, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a scraper 102 is also included; a scraper 102 is connected to the opposite sides of the two bellows 5 .

[0030] Each scraper 102 is provided with a sponge block 10201 ; each sponge block 10201 is in contact with the surface of the wire 1 .

[0031] Each scraper blade 102 is provided with a magnet 10202 .

[0032] When the corrugated cover 5 is stretched, the scraper 102 slides along the surface of the wire 1, thereby cleaning the dust and impurities attached to the wire 1, reducing the impurities attached to the surface of the wire 1 and extending the service life of the wire 1. At the same time, the sponge block 10201 is in contact with the surface of the wire 1 to clean the surface of the wire 1 while preventing the surface of the wire 1 from being damaged by friction with the scraper 102.

[0033] It is also considered that the user can also press the pressure rod 103 to keep the elastic valve membrane 106 in an open state. When the corrugated cover 5 is stretched to half the length of the wire 1, the user presses the corrugated cover 5 to expel the air inside it, so that the corrugated cover 5 is wrapped around the surface of the wire 1, and finally releases the pressure rod 103 to close the elastic valve membrane 106. At this time, the corrugated cover 5 can be used as a conventional elastic rubber wrapping material to waterproof and dustproof the wire 1. Similarly, the user unfolds another corrugated cover 5, and uses the magnets 10202 on the two scrapers 102 to attract each other, thereby completely wrapping the wire 1, and using the non-inflated corrugated cover 5 to reduce the space occupied by the wire 1, so that the corrugated cover 5 can be switched between conventional waterproof and dustproof and inflatable protection according to the user's usage needs.
