Description

Technical Field

[0001] This disclosure relates to the field of electronic facilities technology, and in particular to a magnetic data cable plug-in connector, a data cable plug-in interface, and a data cable. Background Technology

[0002] Magnetic connectors are a new type of quick-connect component developed in modern industry. They can be widely used in various electronic products or applications, such as the magnetic clasp used in Apple tablet bags and magnetic data cables for mobile phone charging. The magnetic connector plugging and unplugging method avoids the drawbacks of traditional pin plugging, such as detachment and excessive force. It has a novel and convenient structure.

[0003] Magnetic data cables connect the charging plug and data cable using magnetic attraction, and their charging interface is replaceable. (See instruction manual attached.) Figure 1 The magnetic data cable shown uses a replaceable plug connector. The user first inserts the replaceable charging connector into the terminal's charging port, and then connects the end of the data cable (plug connector) to the charging connector (plugged into the terminal's charging port) magnetically to realize the data cable function. The magnetic data cable can be unplugged to replace different charging interfaces, which is quite convenient.

[0004] While existing magnetic data cables are convenient to use, the following problems have been found in actual use:

[0005] Existing magnetic data cables only change the connection method; the connector structure remains a fixed plug-in type. The magnetic connector connects to the charging connector via magnetism. However, external interference, such as a user's slight touch, can easily dislodge the connector, causing it to detach from the charging connector. This can result in the data cable falling off and losing power before the user can even react. This is because the magnetic force between the connector and the charging connector is very weak, making it easy for the connector to detach with a slight touch. Conversely, the charging connector, which is firmly inserted into the charging port of a mobile phone or other terminal, is less likely to detach.

[0006] Based on the aforementioned technical defects, it can also be found that the plug-in electrodes of existing magnetic data cables are fixed on the pin headers of the PCB board inside the plug-in connector. When the plug-in connector is detached, the fixed plug-in electrodes lose contact with the plug-in interface inside the charging connector, leaving no time for the user to react. Summary of the Invention

[0019] As an optional embodiment of this application, the electrode rod may be a stepped shaft electrode rod composed of a first electrode and a second electrode, with the first electrode fitting inside the insulating shell;

[0020] The elastic component includes a spring and a sheet spring respectively disposed at the top and bottom ends inside the insulating housing;

[0021] The first electrode rests against the spring, and the second electrode passes through the spring with its plug-in end extending out of the upper opening of the insulating shell.

[0022] As an optional implementation of this application, the plug-in electrode and the PCB pin header are configured in a one-to-one correspondence, and each plug-in electrode and the corresponding PCB pin header are flexibly connected by a signal transmission line;

[0023] One end of the signal transmission line is fixedly connected to the PCB pin header, and the other end enters the insulating shell of the plug-in electrode and is connected to the first electrode.

[0024] As an optional embodiment of this application, the ring-lock structure may optionally include:

[0025] Several first annular grooves are provided on the outer surface of the second electrode of the plug-in electrode;

[0026] When the plug-in connector and the charging connector are magnetically connected, the first annular groove is engaged with the first ring buckle on the charging connector to strengthen the connection between the plug-in connector and the charging connector.

[0027] In another aspect, this application proposes a data cable plug-in interface, comprising:

[0028] The charging connector described above;

[0029] An electrode interface is provided on the charging connector and corresponds to the plug-in electrode;

[0030] The first ring is located on the inner side of the electrode interface;

[0031] When the plug-in connector and the charging connector are magnetically connected, the first annular groove and the first annular buckle are fastened together to strengthen the connection between the plug-in electrode and the electrode interface.

[0032] As an optional embodiment of this application, the ring-lock structure may optionally include:

[0033] Several second rings are provided on the outer surface of the second electrode of the plug-in electrode;

[0034] When the plug-in connector and the charging connector are magnetically connected, the second ring buckle is engaged with the second ring groove on the charging connector to strengthen the connection between the plug-in connector and the charging connector.

[0044] Technical effects of the present invention:

[0045] This application redesigns the plug-in electrodes of existing magnetic data cables with flexible movement, allowing them to connect to the PCB pin headers within the plug-in connector via a flexible signal transmission line. While ensuring normal operation of the plug-in electrodes, a certain flexible movement distance is maintained between them and the PCB pin headers. Even if the plug-in connector detaches, the plug-in electrodes will remain connected to the PCB pin headers for a short period. Furthermore, this application incorporates a reinforced ring structure between the plug-in electrodes and the plug-in interface within the charging connector, avoiding the unreliability and fragility inherent in a single magnetic connection method. This prevents the plug-in electrodes from easily detaching from the plug-in interface when the connector detaches. The flexible movement distance of the plug-in electrodes, combined with the buffer distance between them and the plug-in interface, prevents insufficient reaction time for the user when the connection between the plug-in interface and the charging connector is lost.

[0057] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0058] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0059] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0060] Example 1

[0061] This application designs the plug-in electrodes of existing magnetic data cables to be flexible, allowing them to connect to the PCB pin headers inside the plug-in connector via a flexible signal transmission line. While ensuring the normal operation of the plug-in electrodes, a certain flexible movement distance can be maintained between them and the PCB pin headers. Even if the plug-in electrodes are detached from the plug-in connector, they will continue to be connected to the PCB pin headers for a short period of time.

[0062] like Figure 2 As shown, this application proposes a magnetic data cable plug-in connector, including a wire 1, a plug-in connector 2 connected to the wire 1, a PCB board 3 disposed on the plug-in connector 2 and having PCB pin headers 4, a magnetic member 6 disposed in the port 5 of the plug-in connector 2, and a plurality of plug-in electrodes 7 passing through the magnetic member 6 and fixedly electrically connected to the PCB pin headers 4, wherein:

[0063] The insertion / removal electrode 7 is movably inserted through the magnetic suction member 6 and is flexibly connected to the PCB pin header 4;

[0064] Also includes:

[0065] A ring-shaped structure is provided on the plug-in connector 2 or the charging connector 17 to enhance the connection strength between the plug-in electrode 7 and the charging connector 17 when the plug-in connector 2 and the charging connector 17 are magnetically connected.

[0066] The magnetic data cable mainly consists of a plug-in connector 2 and a charging connector 17. For details, please refer to the structural design and operating principle of magnetic data cables in the prior art. This embodiment will not describe them further.

[0067] The connector 2 contains several power lines, which are all connected to a PCB board 3 (circuit board). The output is then transmitted externally via PCB pin headers 4 on the PCB board 3. During output, several plug-in electrodes 7 are inserted into the electrode interfaces 18 of the charging connector 17 to complete data connection and initiate data transmission or charging. Currently, the plug-in electrodes 7 are fixedly connected to the PCB pin headers 4 using soldering or similar methods; insertion ensures connection. Conversely, if the plug-in electrodes 7 detach from the electrode interfaces 18, data transmission is immediately interrupted.

[0068] This application sets the plug-in electrode 7 as a movable structure, so that there is a certain movable gap between it and the PCB pin header 4 and the connection is not broken.

[0069] Specifically, such as Figure 3 and 5As shown, each plug-in electrode 7 is flexibly connected to the corresponding pin on the PCB header 4 via a signal transmission line. This increases the movement distance of the plug-in electrode 7. When the plug-in connector 2 detaches from the charging connector 17, the plug-in electrode 7 moves forward a certain distance, dragging the signal transmission line and maintaining data communication / transmission / charging functions with the corresponding pin on the PCB header 4 through the signal transmission line. This prevents the connection between the plug-in electrode 7 and the corresponding pin on the PCB header 4 from being broken off in time, providing a certain reaction time. For minor collisions, the magnetic connection interface can easily cause the plug-in electrode 7 and the electrode interface 18 to detach. However, this application also provides a ring-lock structure between the plug-in electrode 7 and the electrode interface 18. When the plug-in electrode 7 and the electrode interface 18 are magnetically connected, a ring-lock connection (movable buckle) is also formed between the plug-in electrode 7 and the electrode interface 18, thereby strengthening the connection strength between the plug-in electrode 7 and the electrode interface 18, supporting a certain impact force, and preventing the plug-in electrode 7 and the electrode interface 18 from detaching. The term "anti-detachment" here refers only to a description relative to a single magnetic connection method. For example, if a magnetic connection can withstand a maximum force of 10N, then the connection between the reinforced plug-in electrode 7 and the electrode interface 18 in this application can withstand a maximum force of 20N. Therefore, the reinforcement here is only relative.

[0070] In the above manner, when a collision occurs, such as Figure 4 As shown, the electrode rod 8 of the plug-in electrode 7 can move outward a certain distance for buffering. At this time, the end still maintains the connection with the corresponding pin on the PCB pin header 4, which can give the user a certain reaction time to plug in the interface in time.

[0071] like Figure 5 As shown, as an optional embodiment of this application, the plug-in electrode 7 may optionally include:

[0072] Insulating outer casing 12;

[0073] Electrode rod 8;

[0074] Flexible components;

[0075] The insulating outer shell 12 has an adhesive block 15 at the bottom and is hollow inside with an opening at the top.

[0076] The electrode rod 8 is movable inside the insulating shell 12 and its plug-in end extends out of the upper opening of the insulating shell 12;

[0077] The elastic component is disposed inside the insulating housing 12 and confines the electrode rod 8 within the insulating housing 12.

[0078] The insertion / removal electrode 7 mainly consists of an electrode rod 8 enclosed in an insulating shell 12. An elastic component is provided inside the insulating shell 12 to elastically confine the electrode rod 8 within the insulating shell 12, ensuring that the electrode rod 8 can only move a certain distance along the axis of the insulating shell 12 (see attached diagram). Figure 4 (As shown).

[0079] The insulating shell 12 can be fixedly connected to the PCB pin header 4 by heating and melting the adhesive block 15 at the bottom. The upper end of the electrode rod 8 can pass through the upper opening of the insulating shell 12, as detailed in the appendix. Figure 5 and 6 As shown.

[0080] When detachment occurs, electrode rod 8 is dragged outward a certain distance by magnetic attraction and the connecting force of the ring. (Combined with attached...) Figure 4 and 6 As shown. When the pulling force generated during detachment exceeds the sum of the magnetic attraction force and the ring connection force, the electrode rod 8 of the plug-in electrode 7 will detach from the electrode interface 18.

[0081] The schematic diagrams of the plug-in connector 2 and the charging connector 17 under normal connection and disconnection are shown in the attached diagrams. Figure 7 and 8 As shown.

[0082] As an optional embodiment of this application, the electrode rod 8 may be a stepped shaft electrode rod composed of a first electrode 9 and a second electrode 10, with the first electrode 9 fitting inside the insulating shell 12.

[0083] The elastic component includes a spring 11 and a spring sheet 13 respectively disposed at the top and bottom ends inside the insulating housing 12;

[0084] The first electrode 9 abuts against the spring 13, and the second electrode 10 passes through the spring 11 and its plug-in end extends out of the upper opening of the insulating shell 12.

[0085] The electrode rod 8 has a stepped shaft structure, and the upper end of the insulating shell 12 has a stepped hole. A spring 11, located inside the insulating shell 12, is fitted onto the outer surface of the second electrode 10 of the electrode rod 8. When the electrode rod 8 is pulled by an external impact, it can elastically resist the impact. After the impact ends, the electrode rod 8 is reset and returned to the insulating shell 12. The spring piece 13 operates on the same principle. The structure of the electrode rod 8 can refer to the electrode structure of existing data cables; the number is unlimited, and the cross-sectional structure of the electrode rod 8 is not limited. Figure 1 The electrode rod 8 shown is a cylindrical structure.

[0086] The bottom of the insulating shell 12 is provided with an axial fine hole that can accommodate a flexible signal transmission line 14. The signal transmission line 14 is connected to one end of the electrode rod 8, offset from the spring piece 13.

[0087] As an optional implementation of this application, the plug-in electrode 7 is optionally provided in a one-to-one correspondence with the PCB pin header 4, and each plug-in electrode 7 is flexibly connected to the corresponding PCB pin header 4 through a signal transmission line 14.

[0088] One end of the signal transmission line 14 is fixedly connected to the PCB pin header 4, and the other end enters the insulating shell 12 of the plug-in electrode 7 and is connected to the first electrode 9.

[0089] The signal transmission line 14 can be a flexible wire harness or a flexible wire for operational use. Existing publicly available flexible signal transmission lines can be used.

[0090] In this embodiment, a ring-locking structure is also provided between the plug-in electrode 7 and the electrode interface 18. When the plug-in electrode 7 and the electrode interface 18 are magnetically connected, the plug-in electrode 7 and the electrode interface 18 are also connected by a ring-locking structure, which strengthens the connection strength between the plug-in electrode 7 and the electrode interface 18, can support a certain impact force, and prevents the plug-in electrode 7 and the electrode interface 18 from falling off.

[0091] The ring buckle structure is a movable buckle. When it is knocked off by an impact, the pulling force at one end of the data cable reaches the total force of the ring buckle and the magnetic attraction, and the ring buckle will open, and the plug-in electrode 7 and the electrode interface 18 will be separated.

[0092] The ring-shaped structure here can be designed on the plug-in electrode 7 and the electrode interface 18, as long as it can be reinforced by snapping when the plug-in electrode 7 is inserted into the electrode interface 18.

[0093] The following will describe two different movable buckle structures.

[0094] Example 2

[0095] Based on Embodiment 1, this embodiment provides a plug-in interface that matches the charging connector 17 of Embodiment 1.

[0096] like Figure 9 As shown, as an optional embodiment of this application, the ring-shaped structure may optionally include:

[0097] A plurality of first annular grooves 16 are provided on the outer surface of the second electrode 10 of the plug-in electrode 7;

[0098] When the plug-in connector 2 and the charging connector 17 are magnetically connected, the first annular groove 16 is fastened to the first ring buckle 19 on the charging connector 17 to strengthen the connection between the plug-in connector 2 and the charging connector 17.

[0099] In another aspect, this application proposes a data cable plug-in interface, comprising:

[0100] The charging connector 17 is described above;

[0101] Electrode interface 18 is provided on the charging connector 17 and corresponds to the plug-in electrode 7;

[0102] The first ring 19 is disposed on the inner side of the electrode interface 18;

[0103] When the plug-in connector 2 and the charging connector 17 are magnetically connected, the first annular groove 16 and the first annular buckle 19 are fastened together to strengthen the connection between the plug-in electrode 7 and the electrode interface 18.

[0104] In this embodiment, three equally spaced first annular grooves 16 are formed on the outer surface of the second electrode 10 of the plug-in electrode 7. Correspondingly, three first ring buckles 19 (formed protrusions on the inner surface) are reserved on the inner surface of the electrode interface 18 of the charging connector 17, which match the first annular grooves 16. The engagement is strengthened through the cooperation of the first annular grooves 16 and the first ring buckles 19. When the user magnetically connects the plug-in connector 2 to the charging connector 17, the user can easily insert the plug-in connector 2 into the charging connector 17.

[0105] For the application of the data cable plug-in interface, please refer to the charging connector 17 in Example 1 for specific usage.

[0110] When the plug-in connector 2 and the charging connector 17 are magnetically connected, the second ring buckle is engaged with the second ring groove on the charging connector 17 to strengthen the connection between the plug-in connector 2 and the charging connector 17.

[0111] In another aspect, this application also proposes a data cable plug-in interface, including:

[0112] The charging connector 17 is described above;

[0113] Electrode interface 18 is provided on the charging connector 17 and corresponds to the plug-in electrode 7;

[0114] The second annular groove is provided on the inner side of the electrode interface 18;

[0115] When the plug-in connector 2 and the charging connector 17 are magnetically connected, the second annular groove and the second annular buckle are fastened together to strengthen the connection between the plug-in electrode 7 and the electrode interface 18.

[0116] For a detailed understanding, please refer to the structure of Example 2. This example will not be described further.
