Description

Technical Field

[0001] The invention relates to the technical field of USB data cables, in particular to a USB streaming data cable. Background Art

[0002] USB data cables are often used for wired data transmission between two devices. USB connectors are currently the most commonly used data cable connectors and are widely used. For mobile phone data cables, the most common form is a USB connector on one end and a Type-C connector on the other end. In addition, there are also mobile phone data cables with a USB connector on one end and other types of connectors on the other end, but data cables that use USB connectors are generally referred to as USB data cables.

[0003] In the prior art, USB data cables are available in various forms. In order to increase the recognition effect of the data cable when camping outdoors or in a dark environment, or to increase the sense of atmosphere, data cables that can emit a streamer effect are also designed.

[0004] For example, the Chinese utility model patent with application number: CN201720293352.X and name "Data cable and / or charging cable with flowing light throughout" proposes a data cable that will not be broken when wound, can emit light, and the light flows throughout the cable like flowing water.

[0005] However, the existing USB streaming data cable has a larger jack at the USB connector than the Type-C connector, so it is easy to be blocked by dust or other debris during use, or the connector may have poor contact due to dust and debris. In particular, USB data cables on camping vehicles, camping lights, or outdoor power supplies are more likely to be blocked because they are usually used outdoors, where there is a lot of dust, gravel, and suspended matter in the air compared to indoor environments. Moreover, when dust or debris enters the jack of the USB connector, it is easy to short-circuit the line of the streaming part of the data cable, causing the data cable to lose its streaming effect, affecting the user experience.

[0006] In order to solve the problem that the connector of the USB data cable is easily blocked by dust and debris, the Chinese utility model patent with application number: CN201921664568.8 and patent name "A streamer data cable" proposes a solution, which includes a data cable body, a data connector and a power connector, the data connector and the power connector are respectively fixedly installed at both ends of the data cable body, and a connector is fixedly installed at the connection between the data connector, the power connector and the data cable body, and a protective member is provided on the connector; by setting a rotatable protective member on the outside of the data connector, when the data connector is used, the protective member can be rotated to protect the data connector or the power connector. Although the patent sets a rotatable protective member to protect the USB connector and prevent dust or debris from entering the plug of the USB connector, it is easy to be touched by foreign objects during use because it is rotatably installed on the outside of the USB connector, which can easily cause the protective member to deviate and fail to effectively protect the USB connector.

[0007] Therefore, a USB streamer data cable is proposed to ensure that the jack of the USB connector will not be entered by debris. Summary of the invention

[0008] The object of the present invention is to provide a USB streaming data cable to solve the problem that debris easily enters the jack of the USB connector, causing the streaming data cable to be unusable or even causing the streaming data cable to lose its streaming effect.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] A USB streamer data cable comprises a data cable body capable of emitting streamer light, a Type-C connector is arranged at one end of the data cable body, a USB connector is arranged at the other end of the data cable body, the USB connector comprises a plastic base, four metal sheets for transmitting signals matching the USB female connector are arranged on the upper surface of the plastic base, the four metal sheets are all connected to the data cable body, a metal shell matching the USB female connector is sleeved on the plastic base, a locking hole matching the USB female connector is provided on the metal shell, a plug hole is formed between the upper surface of the plastic base and the metal shell, a plastic package is arranged at the position where the plastic base is connected to the data cable body, the plastic package closes one end of the plug hole, a spring groove is provided in the plastic package, the opening of the spring groove is horizontally facing the plug hole and aligned with the plug hole, a baffle for closing the plug hole is slidably installed inside the plug hole, and a push spring is arranged inside the spring groove; one end of the spring is fixedly connected to the spring groove, and the other end is fixedly connected to the baffle; the push spring keeps pushing the baffle toward one end of the plug hole away from the plastic package.

[0011] The baffle is used to close the jack of the USB connector, and the push spring is used to keep the baffle at the end of the jack away from the plastic package. In this way, both ends of the jack can be closed, effectively reducing the possibility of dust or other debris entering the jack, avoiding clogging of the jack, and also preventing dust or debris from adhering to the metal sheet to affect the contact effect between the data cable and the USB female connector during use, ensuring the stability of signal reception and transmission during use of the data cable. In addition, since the baffle is slidably installed inside the metal shell, it is not easy to be offset due to collision with foreign objects, and the baffle can stably and effectively close the jack.

[0012] When the USB connector is inserted into the USB female connector, the USB female connector can push the baffle to move in the direction of the plastic package, and the baffle will not affect the connection between the USB connector and the USB female connector. After the USB connector is pulled out of the USB female connector, the push spring will re-close the jack.

[0013] Preferably, the baffle is made of plastic material, and four scrapers are arranged at the bottom of the baffle. The four scrapers are all made of metal, and the four scrapers are respectively aligned with four metal sheets, and the four scrapers are respectively matched with the widths of the four metal sheets.

[0014] When the baffle slides inside the socket, the bottom of the baffle will slide and contact with the upper surface of the plastic base, that is, the bottom of the baffle will rub against the upper surface of the plastic base. After the material of the baffle is set to plastic, since the material of the plastic base is plastic, during the friction between the bottom surface of the baffle and the upper surface of the plastic base, due to the self-lubricating effect of the plastic, the friction between the plastic base and the baffle during the sliding process will be reduced, which helps to avoid the baffle from getting stuck due to excessive friction during the sliding process, and ensures the stability of the baffle during use.

[0015] Because the hardness of the metal sheet is greater than that of the baffle made of plastic, aligning four metal sheets at the bottom of the baffle and setting four scrapers can effectively prevent the scrapers from wearing the bottom of the baffle. In addition, the scrapers can scrape the surface of the metal sheet during the sliding of the baffle, reducing the oxide layer on the surface of the metal sheet, which helps to improve the contact effect between the metal sheet and the USB female connector, and ensure the stability of signal transmission during the use of the data cable. And because the baffle is plastic, the scraper is installed on the baffle made of plastic material, which can effectively prevent the scraper from contacting other metal parts of the data cable except the metal sheet, and avoid the occurrence of short circuits in the internal circuits of the data cable.

[0016] Preferably, a triangular stabilizing block is provided on one side of the baffle plate facing the plastic package, one right-angled side of the stabilizing block is fixedly connected to the baffle plate, and the other right-angled side is slidably fitted with the upper surface of the plastic base, and a avoidance groove for accommodating the stabilizing block is provided on the plastic package. The stabilizing block can improve the stability of the baffle plate during movement, and at the same time prevent the baffle plate from tilting and failing to completely close the jack after long-term use, thereby improving the stability of the baffle plate after long-term use. The avoidance groove ensures that the stabilizing block does not occupy the space inside the jack when the USB connector is inserted into the USB female connector, thereby avoiding affecting the stability of the USB connector when plugging into the USB female connector.

[0017] Preferably, a locking groove is provided on the side wall of the plastic package, and the locking groove is vertical and passes through the avoidance groove; a locking block is slidably installed inside the locking groove, one end of the locking block is located inside the locking groove, and the other end extends out of the plastic package; a locking spring is horizontally arranged inside the locking groove, one end of the locking spring is fixedly connected to the bottom of the locking groove, and the other end is fixedly connected to the locking block, and the locking spring is used to keep the locking block pushed toward the outside of the locking groove; a downwardly protruding locking portion is provided at the bottom of the locking block, an inclined guiding portion is provided on the side of the locking portion facing the baffle, and a blocking portion perpendicular to the locking groove is provided on the side of the locking portion facing away from the baffle; a hook is provided on the side of the stabilizing block facing the avoidance groove, and an inclined extruding portion is provided at the front end of the hook, and the extruding portion is aligned with the guide portion along the direction of the avoidance groove.

[0018] However, when the USB connector is inserted into the USB female connector, the USB female connector pushes the baffle to move in the direction of the plastic package, compressing the push spring. When the stabilizing block is inserted into the avoidance groove, the inclined extrusion portion at the front end of the hook on the stabilizing block will contact the inclined guide portion on the locking portion. As the stabilizing block continues to move into the avoidance groove, the extrusion portion will also continue to squeeze the guide portion and give the guide portion a component force toward the bottom of the locking groove. Eventually, the hook will drive the locking block to move in the direction of the bottom of the locking groove until the hook passes over the locking block. When the hook passes over the locking block, the locking spring will push the locking block toward the outside of the plastic package again, and the locking block will reset. At this time, the hook is hooked onto the blocking portion, which blocks the hook from moving in the direction of the baffle, and the push spring cannot return to its natural state.

[0019] After the locking block and the hook are provided, when the USB connector is inserted into the USB female connector, the locking block cooperates with the hook to push the spring to lock, thereby preventing the USB connector from being separated from the USB female connector due to the spring being pushed back.

[0020] When the USB connector is pulled out from the USB female connector, press the locking block toward the bottom of the locking groove by hand. After the hook and the blocking part are dislocated, the push spring returns to its natural state under the action of its own elastic force. The baffle can be reset and re-closed under the elastic force of the push spring to prevent dust and debris from entering the socket.

[0021] At the same time, due to the provision of the locking block and the hook, the elastic force of the push spring can be appropriately increased. In this way, when the USB connector needs to be pulled out from the USB female connector, it is only necessary to press the locking block toward the bottom of the locking groove, and the USB connector can be ejected from the USB female connector by utilizing the elastic force of the push spring reset, which is convenient for the user to pull out the data cable from the USB female connector, thereby improving the convenience of using the data cable. In addition, since the push spring drives the baffle to reset, the baffle moves linearly along the metal shell, so the elastic force of the push spring is used to pull out the USB connector, which can avoid the situation where the USB connector is not pulled out parallel to the USB female connector when the user pulls out the USB connector by himself, and avoids the USB connector from being distorted and damaged. This ensures the service life of the USB connector.

[0022] Preferably, a dustproof plate for covering the locking hole is horizontally fixed on the top of the baffle, the dustproof plate is parallel to the top of the metal shell, the top of the dustproof plate is in contact with the inner top of the metal shell, and a storage groove for accommodating the dustproof plate is provided on the plastic package.

[0023] The dust plate moves with the baffle. When the push spring is in the natural state, that is, when the baffle closes the port of the jack, the baffle fits against the inner top of the metal shell and closes the locking hole on the metal shell, preventing dust from entering the jack from the locking hole, further preventing the jack from being contaminated by dust and debris, ensuring the cleanliness of the metal sheet, and ensuring the stability and service life of the USB connector. When the baffle moves toward the plastic package, the dust plate moves with the baffle and is finally inserted into the storage slot.

[0024] Preferably, a disc is provided at one end of the locking block outside the plastic package, and the area of ​​the disc is larger than that of the locking block. The disc can increase the contact area between the user's finger and the locking block when the user presses the locking block, thereby reducing the pressure between the user's finger and the locking block, which helps to improve the comfort of the user when pressing the locking block.

[0025] Preferably, the dustproof plate is made of plastic.

[0026] The top of the dust shield will contact the inner top of the metal shell, and since the contact area between the dust shield and the metal shell is larger than the contact area between the metal sheet and the scraper, in order to reduce the friction between the dust shield and the metal shell, the dust shield is made of self-lubricating plastic material. This ensures that the dust shield and baffle can slide smoothly, improving the stability of the data cable during use.

[0027] Preferably, a metal reinforcing plate is sandwiched inside the dustproof plate, and a sharp cone portion is provided on the side of the dustproof plate facing the storage slot. The reinforcing plate can improve the strength of the dustproof plate, prevent the dustproof plate from bending due to insufficient strength after long-term use and being unable to be smoothly inserted into the storage slot, thereby affecting the movement of the baffle, and ensure the movement stability of the baffle during use. The sharp cone portion helps to guide the dustproof plate, allowing the dustproof plate to enter the storage slot more smoothly.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Compared with the existing USB streamer data cables, the USB streamer data cable designed by the present invention has a baffle plate slidably installed inside the USB connector, and the baffle plate cooperates with the push spring to close the jack on the USB connector, so as to prevent dust or other debris from entering the jack of the USB connector when the USB connector is not in use and causing pollution inside the USB connector, thereby ensuring the cleanliness of the inside of the USB connector and further ensuring the connection stability between the USB connector and the USB female connector when in use. And because the baffle plate is arranged inside the jack, it will not be offset due to collision with foreign objects, and the jack can be stably closed.

[0030] 2. A USB streaming data cable designed by the present invention has a baffle made of plastic material. The self-lubricating property of the plastic is used to ensure the smooth sliding of the baffle, and the baffle is provided with a plurality of scrapers made of metal corresponding to the plurality of metal sheets. The scrapers scrape the metal plates by the movement of the baffle to reduce the oxide layer of the metal plates, thereby ensuring the stability of signal transmission during the use of the data cable.

[0031] 3. The USB streamer data cable designed by the present invention is also provided with a locking block and a hook. The locking block cooperates with the hook to lock the push spring, ensuring that the push spring will not push the USB connector away from the USB female connector when the USB connector is inserted into the USB female connector, thereby ensuring stability during the plugging process. In addition, when the locking block unlocks the push spring, the elastic force of the push spring can be used to eject the USB connector from the USB female connector, thereby improving the convenience of pulling out the USB connector.

[0043] refer to Figure 2 , Figure 3 and Figure 8 A dustproof plate 19 for covering the locking hole 304 is fixed horizontally on the top of the baffle 6. The dustproof plate 19 is made of plastic material, and a metal reinforcing plate 22 is sandwiched inside the dustproof plate 19. The reinforcing plate 22 is made of aluminum alloy. A pointed cone portion 23 is provided on the side of the dustproof plate 19 facing the storage groove 20. The dustproof plate 19 is parallel to the top of the metal shell 303, and the top of the dustproof plate 19 is in contact with the inner top of the metal shell 303. A storage groove 20 for accommodating the dustproof plate 19 is provided on the plastic package 4.

[0044] refer to Figures 2 to 8The plastic package 4 is provided with an avoidance groove 10, and a locking groove 11 is provided on the side wall of the plastic package 4. The locking groove 11 is vertical and penetrates the avoidance groove 10; a locking block 12 is slidably installed inside the locking groove 11, one end of the locking block 12 is located inside the locking groove 11, and the other end extends out of the plastic package 4; a locking spring 13 is horizontally arranged inside the locking groove 11, one end of the locking spring 13 is fixedly connected to the bottom of the locking groove 11, and the other end is fixedly connected to the locking block 12, and the locking spring 13 is used to keep the locking block 12 pushed toward the outside of the locking groove 11; a downwardly protruding protrusion is arranged at the bottom of the locking block 12 A locking portion 14 is provided with an inclined guide portion 15 on the side of the locking portion 14 facing the baffle 6, and a blocking portion 16 perpendicular to the locking groove 11 is provided on the side of the locking portion 14 facing away from the baffle 6; a triangular stabilizing block 9 is provided on the side of the baffle 6 facing the plastic package 4, one right-angled side of the stabilizing block 9 is fixedly connected to the baffle 6, and the other right-angled side is slidably fitted with the upper surface of the plastic base 301, and a hook 17 is provided on the side of the stabilizing block 9 facing the avoidance groove 10, and an inclined extrusion portion 18 is provided at the front end of the hook 17, and the extrusion portion 18 is aligned with the guide portion 15 along the direction of the avoidance groove 10.

[0045] refer to Figure 1 and Figure 2 When the data line is not in use, the push spring 7 is in a natural state to keep the baffle 6 at the end of the jack 305 away from the plastic package 4, and the baffle 6 closes the opening of the jack 305. At this time, the dustproof plate 19 on the top of the baffle 6 also closes the two locking holes 304 on the top of the metal shell 303. The jack 305 is in a completely closed state at this time, and the metal sheet 302 inside is protected to prevent dust from contaminating the metal sheet 302 and prevent debris from clogging the inside of the jack 305.

[0046] When using the data cable, the USB connector 3 of the data cable is inserted into the USB female connector on a computer or other device and is electrically connected to the USB female connector through four metal sheets 302. The four metal sheets 302 inside the USB connector 3 transmit the signal to the Type-C connector 2 at the other end through the data cable body 1. The Type-C connector 2 is connected to a mobile phone or other electronic device. In this way, the two devices can be connected and are ready for data transmission, and data transmission can start at any time.

[0047] refer to Figure 5When the USB connector 3 is inserted into the USB female connector, the part of the USB female connector that matches the socket 305 will enter the socket 305. In the process of entering the socket 305, the part of the USB female connector that matches the socket 305 will push the baffle 6 and push the baffle 6 toward the direction of the plastic package 4. When the stabilizing block 9 on the plug board enters the avoidance groove 10, the inclined extrusion part 18 at the front end of the hook 17 on the stabilizing block 9 on the plug board will contact the inclined guide part 15 on the locking part 14. As the stabilizing block 9 continuously moves toward the avoidance groove 10, the extrusion part 18 will also continuously squeeze the guide part 15 and give the guide part 15 a component force toward the bottom of the locking groove 11. Finally, the hook 17 will drive the locking block 12 to move toward the bottom of the locking groove 11 until the hook 17 passes over the locking block 12. After the hook 17 passes over the locking block 12, the locking spring 13 will push the locking block 12 toward the outside of the plastic package 4 again, and the locking block 12 will be reset. When the locking block 12 is pushed toward the outside of the plastic package 4 again by the locking spring 13, a "click" sound is emitted, indicating that the USB connector 3 and the USB female connector are plugged into place. At this time, the hook 17 is hooked onto the blocking portion 16, and the blocking portion 16 blocks the hook 17 from moving toward the baffle 6, and the pushing spring 7 cannot return to the natural state, so the baffle 6 naturally cannot move toward the USB female connector.

[0048] When the baffle 6 moves toward the plastic package 4, the dustproof plate 19 also moves with the baffle 6. When the baffle 6 passes through the locking hole 304, the dustproof plate 19 no longer blocks the locking hole 304, and the reed on the USB female connector can be inserted into the locking hole 304 to lock the USB connector 3. When the baffle 6 moves into place, the dustproof plate 19 is also inserted into the storage slot 20.

[0049] refer to Figure 1 and Figure 2 When the USB connector 3 needs to be pulled out from the USB female connector, the user only needs to press the disc 21 toward the bottom of the locking groove 11, and the locking block 12 will move toward the bottom of the locking groove 11 along with the disc 21, and the locking spring 13 will be compressed. When the blocking portion 16 on the locking block 12 is separated from the hook 17, the blocking portion 16 is no longer an obstacle, and the push spring 7 returns to its natural state under its own elastic force. In the process of returning to the natural state, the push spring 7 pushes the baffle 6 in a direction away from the plastic package 4. The baffle 6 pushes the end of the part of the USB female connector inserted into the jack 305 and gives itself a reaction force. The reaction force can be used to pop the USB connector 3 out of the USB female connector, so that the USB connector 3 is separated from the USB female connector.

[0050] After the USB connector 3 is separated from the USB female connector, the baffle 6 and the dustproof plate 19 are reset and the opening of the jack 305 and the locking hole 304 are closed to ensure that dust or debris does not enter the inside of the jack 305. The whole operation process is now completed.

[0051] It should be noted that during the movement of the baffle 6, the scraper 8 will rub against the metal sheet 302 to scrape off the oxide layer on the metal sheet 302, thereby ensuring the contact stability between the metal sheet 302 and the USB female connector and ensuring that the electrical signal can be stably transmitted to the Type-C connector 2.

[0052] A specific embodiment of the present invention is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above described embodiment. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments without departing from the principles and ideas of the present invention should still fall within the scope of protection of the present invention.
