[0002] In the field of electronic device connection, data cables, as key accessories for realizing data transmission and charging functions, are of great importance. However, there are significant drawbacks in the current interface design of data cables. The interfaces of data cables are usually exposed to the external environment. During long-term use and storage, the interface part is extremely prone to accumulating dust, dirt, and other tiny particles. Due to the long-term exposure of the data cable interface to the air, dust accumulation frequently occurs, and dust, dirt, etc. can smoothly enter the interior of the interface, thereby causing the problem of metal oxidation.

[0003] Once a metal forms an oxide layer, its conductivity will be seriously affected because the presence of the oxide layer hinders the smooth conduction of electrons, resulting in poor contact. The problem of poor contact is extremely common in actual use, specifically manifested as frequent interruptions during device charging, a significant slowdown in the charging speed, and even in some serious cases, the device cannot be charged normally at all.

Detailed Embodiment

[0023] The present invention will be further described in conjunction with the following embodiments.

[0025] The housing 1 is movably provided with a button 5; the button 5 is connected with a pulling assembly; the button 5 drives the baffle 41 to move through the pulling assembly; one end of the housing 1 is telescopically and movably provided with an ejector rod 61 horizontally; the ejector rod 61 is connected with an insertion assembly; the ejector rod 61 drives the interface seat 3 to move through the insertion assembly.

[0026] Specifically, for the charging cable with dust-proof storage described in this embodiment, in the natural state, the baffle 41 shields the insertion opening 11 of the housing 1, so that the interface seat 3 is stored in the limiting channel 12, avoiding problems such as dust and oxidation; when it is necessary to plug in with an external connector, the baffle 41 is driven to move by the button 5 and the pulling assembly, so as to open the insertion opening 11, and when the housing 1 abuts against the external connector, the external connector presses the ejector rod 61 to contract, and the ejector rod 61 drives the interface seat 3 to extend through the insertion assembly to complete the plugging with the external connector.

[0027] For the charging cable with dust-proof storage described in this embodiment, a pulling chute 42 is provided horizontally along the top of the housing 1; the pulling assembly includes a pulling slider 43 slidably disposed in the pulling chute 42, a pulling pulley 44 rotatably disposed on the housing 1, and a pulling drawstring 45 disposed between the top of the pulling slider 43 and the baffle 41; the pulling drawstring 45 abuts against the pulling pulley 44; the button 5 is vertically movably disposed on the pulling slider 43. For the charging cable with dust-proof storage described in this embodiment, a pulling spring 46 is provided between the top of the baffle 41 and the housing 1.

[0028] Specifically, for the charging cable with dust-proof storage described in this embodiment, in the natural state, due to the action of the pulling spring 46, the baffle 41 shields the insertion opening 11, so that the interface seat 3 is stored in the limiting channel 12, avoiding problems such as dust and oxidation; when it is necessary to open the insertion opening 11, by pushing the button 5 to move, the pulling slider 43 is caused to move in the pulling chute 42. During the movement of the pulling slider 43, the baffle 41 is driven to move upward by the pulling drawstring 45, so as to open the insertion opening 11.

[0029] For the charging cable with dust-proof storage described in this embodiment, a cleaning brush strip 47 is telescopically movably disposed at the bottom of the baffle 41. Through the above setting, the interface seat 3 can be cleaned.

[0030] A charging cable with dust-proof storage according to this embodiment, the plugging component includes a guide rod 7 arranged in the limiting channel 12 along the horizontal direction and a limiting plate 31 arranged on the interface seat 3; the limiting plate 31 is connected with the limiting channel 12 in a form-fit manner; the guide rod 7 is rotatably arranged in the limiting channel 12; a first spiral groove 71 is arranged on the outer wall of the guide rod 7; the limiting plate 31 is provided with a first limiting pin 32 that cooperates with the first spiral groove 71; the ejector rod 61 is used to drive the guide rod 7 to rotate. A charging cable with dust-proof storage according to this embodiment, one end of the guide rod 7 close to the plugging opening 11 is provided with a driving cavity 72; a driving rod 62 is movably arranged in the driving cavity 72 along the horizontal direction; one end of the driving rod 62 is connected with the ejector rod 61 in a form-fit manner; a second spiral groove 73 is arranged on the inner wall of the driving cavity 72; the driving rod 62 is provided with a second limiting pin 63 that cooperates with the second spiral groove 73. A charging cable with dust-proof storage according to this embodiment, a large plugging spring 64 is arranged between one end of the driving rod 62 and the ejector rod 61; a small plugging spring 65 is arranged between the other end of the driving rod 62 and the driving cavity 72; the rigidity of the large plugging spring 64 is greater than that of the small plugging spring 65. A charging cable with dust-proof storage according to this embodiment, a mounting plate 8 is arranged in the housing 1; a fixing pin 81 is movably arranged on the mounting plate 8 along the vertical direction; the limiting plate 31 is provided with a fixing groove 33 that cooperates with the fixing pin 81. A charging cable with dust-proof storage according to this embodiment, the mounting plate 8 is provided with a lever member 82; the middle of the lever member 82 is slidably hinged to the mounting plate 8; one end of the lever member 82 is hinged to the fixing pin 81; a fixing spring 83 is arranged between the other end of the lever member 82 and the mounting plate 8. A charging cable with dust-proof storage according to this embodiment, an unlocking seat 9 is movably arranged on the mounting plate 8 along the vertical direction; the other end of the lever member 82 abuts against the bottom of the unlocking seat 9; a strip-shaped limiting groove 91 is arranged on the unlocking seat 9 along the horizontal direction; the bottom of the button 5 is movably arranged in the strip-shaped limiting groove 91.

[0031] Specifically, for the charging cable with dust-proof storage according to this embodiment, in the natural state, the baffle 41 shields the plugging opening 11 of the housing 1, so that the interface seat 3 is received in the limiting channel 12, avoiding problems such as dust and oxidation. And at this time, under the action of the large plugging spring 64 and the small plugging spring 65, the end of the ejector rod 61 protruding from the housing 1;

[0032] When it is necessary to plug in an external connector, first, the housing 1 is abutted against the external connector, and the ejector rod 61 is compressed by the external connector. At this time, since the interface seat 3 abuts against the baffle 41, the interface seat 3 cannot move outward, that is, the limiting plate 31 cannot move, resulting in the guide rod 7 being unable to rotate. That is to say, in this state, the driving rod 62 cannot move. Therefore, the ejector rod 61 can only move in the direction of the driving rod 62, and a relative displacement occurs between the ejector rod 61 and the driving rod 62, and the large insertion spring 64 is in a compressed state.

[0033] Then the user moves the push button 5, so that the pulling slider 43 moves in the pulling chute 42. During the movement of the pulling slider 43, the baffle 41 is driven to move upward by the pulling drawstring 45, so that the insertion opening 11 is opened. When the insertion opening 11 is opened, at this time, since the rigidity of the large insertion spring 64 is greater than that of the small insertion spring 65, the large insertion spring 64 needs to reset. Therefore, at this time, the large insertion spring 64 pushes the driving rod 62 to move in the direction of the small insertion spring 65. During the movement of the driving rod 62, the guide rod 7 is rotated by the action of the second spiral groove 73 and the second limit pin 63. While the guide rod 7 is rotating, the limiting plate 31 is moved by the action of the first spiral groove 71 and the first limit pin 32, so that the interface seat 3 extends out of the insertion opening 11 and completes the plugging with the external connector. And during the movement of the interface seat 3, the cleaning brush strip 47 can clean the interface seat 3.

[0034] Until the limiting plate 31 moves to the position of the fixing pin 81, the fixing pin 81 is engaged with the fixing groove 33, thereby fixing the position of the interface seat 3, so that the charging cable for dust-proof storage is stably plugged into the external connector.

[0035] When it is necessary to disconnect from the external connector, press the button 5 downward, so that the unlocking seat 9 moves downward. The unlocking seat 9 drives the other end of the lever member 82 to move downward, so that the fixing pin 81 moves upward and exits from the fixing groove 33. Then, under the reset action of the large insertion spring 64 and the small insertion spring 65, the interface seat 3 retracts into the limiting channel 12 again, and the ejector rod 61 protrudes from one end of the housing 1 again. And under the action of the pulling spring 46, the baffle 41 covers the insertion opening 11 again.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
