[0001] The present invention provides a mobile device accessory connector, and more particularly relates to a mobile device accessory connector that can connect a mobile device and a mobile device accessory to each other. Prior Technology

[0002] Portable mobile devices are indispensable daily necessities in modern society. Examples include smartphones, tablets, smartwatches, and e-readers, all of which bring great convenience to people's lives and work. In recent years, users of these portable mobile devices have been attaching mobile ring holders to the back of their devices or the housings containing them. When the ring holder is unfolded, the user's finger can pass through it, increasing the means of securing the device and reducing the chance of it falling. Furthermore, when the mobile device rests on a flat surface such as a table or floor, the ring holder can also serve as a stand, improving the convenience of watching videos or browsing the web. Summary of the Invention

[0003] However, current ring holders only have the aforementioned attachment and unfolding functions, lacking compatibility with other peripheral accessories (such as card holders, power banks, or clips). When users want to use their mobile devices and peripheral accessories simultaneously, they need to free up both hands to hold the mobile devices and peripheral accessories separately, which is not only inconvenient to use, but also makes the separate accessories more scattered and easy to lose. In addition, the design of the ring holders is too simple and rigid.

[0080] The foregoing description and other technical contents, features, and effects of this invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. It is worth noting that the directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. Furthermore, in the following embodiments, the same or similar elements will be represented by the same or similar reference numerals.

[0081] Please refer to Figures 1 and 2, where Figure 1 is a perspective view of the first embodiment of the mobile device accessory connector of the present invention working in conjunction with a mobile device, and Figure 2 is a perspective view of the mobile device accessory connector in Figure 1. The mobile device accessory connector 1A of this embodiment is applicable to a mobile device 2, where the mobile device 2 is, for example, a smartphone. However, in other possible embodiments, the mobile device 2 can also be a smartwatch, tablet computer, personal digital assistant, digital camera, or handheld game console, etc., and the present invention does not limit this to such devices. On the other hand, the mobile device accessory connector 1A includes a first connector 100A and a second connector 200A, wherein the second connector 200A is movably connected to the first connector 100A, and the second connector 200A is selectively located relative to the first connector 100A in a first position and a second position.

[0082] In detail, in this embodiment, the first connector 100A and the second connector 200A are generally annular. The first connector 100A includes an outer ring portion 110A, which surrounds a first receiving hole 160A. The second connector 200A includes an inner ring portion 210A, which surrounds a second receiving hole 260A. The diameter of the first receiving hole 160A is greater than or equal to the outer diameter of the inner ring portion 210A. Simultaneously, the second connector 200A may also include a pivot portion 230A, which may be a protrusion with a thickness substantially the same as that of the inner ring portion 210A, disposed on the outer edge of the inner ring portion 210A and protruding outward along a radial direction of the inner ring portion 210A. The first connector 100A may be provided with a clearance gap 170A to accommodate the pivot portion 230A of the second connector 200A. In this embodiment, the outer ring portion 110A may be formed into a C-shaped ring, with the aforementioned clearance gap 170A formed between the two ends of the C-shaped ring. With this configuration, the second connector 200A is pivotally connected to the outer ring portion 110A through the pivot portion 230A, and when the second connector 200A is in a first position relative to the first connector 100A, that is, when the second connector 200A is closed relative to the first connector 100A, the second connector 200A can be accommodated in the first receiving hole 160A and the clearance gap 170A. In some possible embodiments, the thickness of the inner ring portion 210A and the pivot portion 230A is substantially less than or equal to the thickness of the outer ring portion 110A. Therefore, when the second connector 200A is in the above-mentioned retracted position, the orthographic projection of the second connector 200A on an axial direction D of the outer ring portion 110A is located within the orthographic projection of the outer ring portion 110A on the axial direction D, and the projection width of the second connector 200A is less than or equal to the projection width of the outer ring portion 110A, that is, the second connector 200A can be housed inside the first connector 100A.

[0083] In addition, the mobile device accessory connector 1A is adapted to be detachably coupled to the mobile device 2, thereby allowing the user to more conveniently retrieve and use the mobile device 2. As shown in Figures 1 and 2, one of the first connector 100A and the second connector 200A has at least one device engagement portion. In this embodiment, the first connector 100A has a device engagement portion 120A, and the device engagement portion 120A is a magnet corresponding to the shape and size of the outer ring portion 110A. Furthermore, as shown in Figure 2, the outer ring portion 110A may be formed with at least one magnet receiving groove 116A, wherein the size and number of magnet receiving grooves 116A correspond to the magnet, the magnet is disposed in the magnet receiving groove 116A, and the orthogonal projection of the magnet on the axial direction D of the outer ring portion 110A is located within the orthogonal projection of the first connector 100A on the axial direction D, that is, the magnet is substantially thinner than the outer ring portion 110A or the same width. With this configuration, the device coupling portion 120A can be housed inside the outer ring portion 110A. When the user needs to retrieve or use the mobile device 2, the first connector 100A can be attached to the surface of the mobile device 2, allowing the device coupling portion 120A to temporarily connect with a magnetic feature on the mobile device 2 (e.g., a MAGSAFE magnet array on a smartphone). At this time, the user can further adjust the second connector 200A relative to the first connector 100A to a second position. That is, when the second connector 200A is unfolded relative to the first connector 100A, the inner ring portion 210A can pivot to the outside of the first connector 100A and the first receiving hole 160A through its pivotal relationship with the outer ring portion 110A, forming a non-zero angle with the outer ring portion 110A. In some preferred embodiments, the diameter of the second receiving hole 260A is greater than or equal to the width of the user's finger, so the user can insert his finger through the second receiving hole 260A of the unfolded second connector 200A and use the mobile device accessory connector 1A as a ring holder, which is quite simple and convenient.

[0084] It is worth noting that the way the first connector 100A is connected to the mobile device 2 is not limited to magnetic connection. In some possible embodiments, the device connection portion 120A can also be adhesive foam or double-sided tape, and the mobile device accessory connector 1A is adapted to be attached to the mobile device 2 or a mobile device housing for housing the mobile device 2 through the device connection portion 120A. In this way, when the user wants to take out or use the mobile device 2, the device connection portion 120A can be attached to the surface of the mobile device 2, and the two can be separated after use, thus achieving the effect of detachable connection.

[0085] Alternatively, in some possible embodiments, the mobile device 2 or the mobile device housing is formed with a groove or protrusion that can engage with an external object, and the device coupling portion 120A is a corresponding engaging protrusion or engaging groove, and the mobile device accessory connector 1A is adapted to engage with the mobile device 2 or the mobile device housing through the device coupling portion 120A, thus achieving a similar effect. Since specific details will be described in more detail in other embodiments below, they will not be repeated here.

[0086] It should be noted that in other possible embodiments, the device connecting part 120A may also be disposed on the second connector 200A, or the inner and outer configuration relationship of the first connector 100A and the second connector 200A may be interchanged, that is, the diameter of the first receiving hole 160A may be set to be greater than or equal to the width of the user's finger, and the function of extracting the mobile device 2 may be achieved by inserting the finger through the first receiving hole 160A of the first connector 100A which is unfolded relative to the second connector 200A. The present invention does not limit this.

[0087] Please refer to Figures 3 and 4, where Figure 3 is a perspective view showing the interaction between the mobile device accessory connector of Figure 2 and the first embodiment of the mobile device accessory of the present invention, and Figure 4 is a perspective view of the mobile device accessory in Figure 3 from another perspective. Specifically, the mobile device accessory connector 1A of this embodiment is also adapted to be detachably engaged with a mobile device accessory 3A, thereby allowing users to more conveniently carry and use various peripheral accessories. As shown in Figure 3, one of the first connector 100A and the second connector 200A has at least one accessory engaging portion. In this embodiment, the second connector 200A is provided with four accessory engaging portions 220A, and each accessory engaging portion 220A is a locking slot. On the other hand, the mobile device accessory 3A is, for example, a cover and includes a latching member 31A, wherein the latching member 31A includes at least one connecting latching portion 33A. In this embodiment, the latching member 31A includes four connecting latching portions 33A, and each connecting latching portion 33A is a latching protrusion whose shape and size correspond to the accessory latching portion 220A. Therefore, when the user wants to carry or use the mobile device accessory 3A, the connecting latching portion 33A of the mobile device accessory 3A can be latched to the accessory latching portion 220A of the second connector 200A, thereby detachably latching the mobile device accessory 3A to the mobile device accessory connector 1A.

[0088] As shown in Figures 3 and 4, the latching member 31A of this embodiment further includes a latching body 32A, wherein the latching body 32A is, for example, a circular thin cover and has a front side 321A, a rear side 322A, and an outer peripheral surface 323A. The front side 321A and the rear side 322A are opposite to each other, and the outer peripheral surface 323A is disposed on the periphery of the rear side 322A along the circumference of the latching body 32A. The connecting latching portions 33A are disposed at equal intervals along the circumference of the outer peripheral surface 323A. On the other hand, the four accessory latching portions 220A of the second connecting member 200A are also disposed at equal intervals along the circumference of the inner ring portion 210A on the inner edge of the inner ring portion 210A. With this configuration, the equally spaced accessory latches 220A can evenly distribute the force generated when disassembling or assembling the mobile device accessory 3A, avoiding the force being applied locally to the accessory latches 220A or connector latches 33A at specific locations, thereby reducing the probability of the second connector 200A or connector latches 33A breaking.

[0089] When the mobile device accessory 3A and the second connector 200A are engaged, the front side 321A of the engaging body 32A will cover the second receiving hole 260A. Therefore, in some possible embodiments, the front side 321A may be configured with colors, patterns, or various cute designs to improve the aesthetic appeal and recognizability of the mobile device accessory 3A. In some other embodiments, the accessory engaging portion 220A may also be configured on the outer edge of the inner ring portion 210A, while the connector engaging portion 33A is correspondingly configured on the inner peripheral surface 324A of the engaging body 32A. When the mobile device accessory 3A and the second connector 200A are engaged, and the second connector 200A is in the first position, the peripheral wall of the engaging body 32A can be embedded in the gap formed between the outer ring portion 110A and the inner ring portion 210A, thereby more effectively blocking the first receiving hole 160A and the second receiving hole 260A.

[0090] As shown in Figure 4, the rear side 322A and inner peripheral surface 324A of the card holder body 32A can surround to form a receiving groove 326A. Herein, the user can place small items, such as coins, tokens, contactless cards, or slips of paper, into the receiving groove 326A. When the second connector 200A is in the first position, these small items are jointly restrained by the rear side 322A, the inner peripheral surface 324A, and the back of the mobile device 2. When the second connector 200A pivots relative to the first connector 100A to the second position, the small items in the receiving groove 326A can be automatically displayed as the mobile device accessory 3A is flipped, meaning the mobile device accessory 3A can be used as a small storage container.

[0091] In addition, the mobile device accessory connector 1A of this embodiment is adapted to be coupled to the mobile device 2 and the mobile device accessory 3A from two different directions. Please refer to FIG5, which is a cross-sectional view along line AA of FIG2. As shown in the figure, the first connector 100A may also include a pivot 130A, wherein the pivot 130A is, for example, a pin, which passes through the pivot portion 230A accommodated in the clearance gap 170A and is inserted into the outer ring portion 110A, thereby allowing the second connector 200A to pivot freely relative to the first connector 100A, and the pivot angle range may be from 0 degrees to 360 degrees, depending on the user's needs. Furthermore, the outer ring portion 110A has a front side 111A and a rear side 112A, wherein the front side 111A and the rear side 112A are opposite to each other, and the magnet receiving groove 116A is provided on the rear side 112A. On the other hand, the inner ring portion 210A has a front side surface 211A, a rear side surface 212A, an outer peripheral surface 213A, and an inner peripheral surface 214A, wherein the front side surface 211A and the rear side surface are opposite to each other, the outer peripheral surface 213A and the inner peripheral surface 214A are opposite to each other, and the accessory latching portion 220A is disposed on the inner peripheral surface 214A. Furthermore, the opening of the engaging groove formed by the accessory latching portion 220A is opened on the front side surface 211A, but the engaging groove does not penetrate the rear side surface 212A. With this configuration, the mobile device accessory connector 1A is adapted to be magnetically fixed to the mobile device 2 through the rear side surface 112A (one side of the mounting device connecting portion 120A) of the outer ring portion 110A, and when the first connector 100A is engaged with the mobile device 2, the connector latching portion 33A of the mobile device accessory 3A can enter the engaging groove from the front side surface 211A of the inner ring portion 210A to latch and fix it to the accessory latching portion 220A. In other words, users can freely choose the order in which they connect with mobile device 2 and mobile device accessory 3A without encountering difficulties where connecting with one would cause interference with the other and prevent them from connecting.

[0092] It is worth mentioning that the mobile device accessory connector 1A in this embodiment also has the function of locking the mobile device accessory 3A in a specific direction. As shown in FIG5, the engagement groove formed by the accessory latching part 220A may include a pair of alignment grooves 222A and a locking groove 224A. The alignment groove 222A extends from the front side 211A of the inner ring part 210A along the axial direction D but does not reach the rear side 212A. The locking groove 224A is arranged adjacent to the alignment groove 222A in the circumferential direction and communicates with the alignment groove 222A. The width of the locking groove 224A in the axial direction D is smaller than the width of the alignment groove 222A in the axial direction D. That is, the locking groove 224A does not communicate with the outside through the front side 211A or the rear side 212A. The entire engagement groove is generally "└" shaped when viewed from the side. On the other hand, the length of the connector locking part 33A in the circumferential direction is substantially equal to the length of the alignment groove 222A in the circumferential direction. Therefore, when the user wants to lock the mobile device accessory 3A and the second connector 200A together, the connector locking part 33A can be aligned with the alignment groove 222A and inserted into the inner ring part 210A. After the connector locking part 33A is inserted into the inner ring part 210A and aligned with the locking groove 224A, the locking body 32A is rotated a certain distance in the circumferential direction so that the connector locking part 33A is inserted into the locking groove 224A. This prevents the mobile device accessory 3A and the second connector 200A from being displaced from the mobile device accessory connector 1A due to relative displacement in the axial direction D.

[0093] It is worth mentioning that, although in this embodiment the alignment groove 222A extends from the front side 211A of the inner ring portion 210A but does not reach the rear side 212A, the present invention is not limited to this. In other embodiments, the alignment groove 222A may also penetrate the second connector 200A along the axial direction D, and the locking groove 224A communicates with the central portion of the alignment groove 222A, so that the entire engaging groove is generally "├" shaped when viewed from the side. In this way, the user can freely choose to insert the mobile device accessory 3A into the engaging groove from the front side 211A or the rear side 212A, increasing the flexibility of the mobile device accessory connector 1A in use. Alternatively, in another embodiment, the alignment groove 222A may extend from the rear side 212A of the inner ring portion 210A but not reach the front side 211A, so that the alignment groove 222A is only open to the rear side 212A. With this configuration, when the first connector 100A is attached to the mobile device 2, the second connector 200A needs to be unfolded to the second position relative to the first connector 100A in order to insert the mobile device accessory 3A into the engaging groove from the rear side 212A of the inner ring portion 210A to complete the installation. Accordingly, when the second connector 200A is in the closed first position relative to the first connector 100A, this structural form can more effectively prevent the mobile device accessory 3A from accidentally detaching.

[0094] In some possible embodiments, the first connector 100A also serves to prevent the mobile device accessory 3A from detaching from the second connector 200A. Specifically, as shown in FIG5, the inner circumferential surface of the outer ring portion 110A and the outer circumferential surface 213A of the inner ring portion 210A are substantially tightly fitted together. However, in other embodiments, the outer ring portion 110A may also extend radially inward from the inner circumferential surface, so that when the second connector 200A is in the first position, the protruding portion of the outer ring portion 110A can block the opening of the engaging groove formed by the accessory locking portion 220A, thereby preventing the mobile device accessory 3A from detaching from the opening.

[0095] Alternatively, in some possible embodiments, the accessory latching part 220A and the connector latching part 33A have a mutual limiting effect during the mutual alignment and latching process. Specifically, in this embodiment, the groove wall of the opening portion of the alignment groove 222A is substantially parallel to the axial direction D. However, in other embodiments, the groove wall of the opening portion can be gradually inclined relative to the axial direction D, that is, the opening of the alignment groove 222A is set to be wider on the outside and narrower on the inside or narrower on the outside and wider on the inside. With such a configuration, when the second connector 200A and the mobile device accessory 3A are fitted together, the connector latching part 33A needs to be slightly inclined relative to the accessory latching part 220A along the axial direction D in order to smoothly fit into the opening of the alignment groove 222A, which can also achieve the effect of preventing the mobile device accessory 3A from slipping out of the opening. When the accessory latching part 220A is a latching protrusion, the surface of the latching protrusion used to fit into the groove on the mobile device accessory 3A can also be gradually inclined relative to the axial direction D, which will not be elaborated here.

[0096] In addition, the mobile device accessory connector 1A can also limit the engagement of the mobile device accessory 3A through other means. As shown in FIG5, in this embodiment, the second connector 200A also has at least one accessory positioning part 240A, wherein the accessory positioning part 240A is, for example, a positioning protrusion, the number of which corresponds to the accessory locking part 220A and is disposed in the locking groove formed by the accessory locking part 220A. On the other hand, the connector locking part 33A has a positioning feature corresponding to the accessory positioning part 240A, which is taken as a positioning recess in this embodiment. When the connector locking part 33A is inserted into the locking groove 224A in the circumferential direction and rotated to a specific position, the accessory positioning part 240A and the positioning feature lock each other, thereby limiting the rotation of the mobile device accessory 3A relative to the second connector 200A in the circumferential direction.

[0097] It is worth mentioning that the limiting relationship between the accessory positioning part 240A and the positioning feature is not limited to a snap-fit ​​mechanism. In some possible embodiments, the accessory positioning part 240A can also be a magnet or magnetic tape, while the positioning feature is a corresponding magnetic component or magnetizing material. The two are limited to each other by magnetic attraction, which can also achieve the same effect.

[0098] It should be noted that all the technical features applied to the accessory latching part 220A can also be applied to the device connecting part 120A. That is, when the device connecting part 120A is a groove or protrusion for latching onto the mobile device 2 or the mobile device housing, the force acting between the device connecting part 120A and the mobile device 2 can be evenly distributed by arranging the device connecting parts 120A at equal intervals, or by setting features such as alignment grooves, locking grooves and accessory positioning parts, so that the device connecting part 120A and the mobile device 2 are mutually limited. These will not be elaborated here.

[0099] It should also be noted that although this embodiment uses the device coupling portion 120A disposed on the outer ring portion 110A and the accessory locking portion 220A disposed on the inner ring portion 210A as an example, the present invention is not limited thereto. In some possible embodiments, both the device coupling portion 120A and the accessory locking portion 220A may be disposed on the outer ring portion 110A. In this case, at least a portion of either the mobile device accessory 3A or the mobile device housing may be coupled to the mobile device accessory connector 1A by being embedded in the first receiving hole 160A or by engaging with each other on the outer peripheral surface of the outer ring portion 110A. With such a configuration, the functions of coupling the mobile device 2 and locking the mobile device accessory 3A can be disposed on the first connector 100A, while the second connector 200A is simply used as a ring for extracting the mobile device 2 and the mobile device accessory 3A, reducing the complexity of component assembly. Similarly, both the device connecting part 120A and the accessory locking part 220A can be arranged in the inner ring part 210A to achieve a similar effect.

[0100] Please refer to Figure 6, which is a perspective view of the mobile device accessory connector in Figure 1 and the cooperative function of the mobile device and the second embodiment of the mobile device accessory of the present invention. The mobile device accessory 3B of this embodiment includes a latching member 31B, wherein the latching member 31B includes a latching body 32B and at least one connecting latching portion 33B. In this embodiment, the latching member 31B includes four connecting latching portions 33B, and these connecting latching portions 33B are engaging protrusions equally spaced along the circumference of the latching body 32B on the outer peripheral surface 323B of the latching body 32B. The main difference from the mobile device accessory 3A is that the latching body 32B forms a communication element receiving groove 326B, and the communication element receiving groove 326B is adapted to receive a communication element 34B.

[0101] In detail, when users have needs such as mobile payment, access control card swipe, or use public transportation, communication components 34B, such as near-field communication (NFC) chips with credit card payment function, access control cards, or radio-frequency identification (RFID) chips with EasyCard sensing function, can be placed in the communication component receiving slot 326B. In this way, when the user clicks the mobile device accessory 3B and the second connector 200A together, the user can easily carry the mobile device 2 and the communication component 34B with the above functions at the same time, thereby achieving the effects of convenient payment and easy sensing.

[0102] In this embodiment, the communication element receiving slot 326B is formed on the front side 321B of the latch body 32B. In this case, the mobile device accessory 3B may also include a cover (not shown), wherein the cover is, for example, a sheet member whose shape and size correspond to the communication element receiving slot 326B. When the user places the communication element 34B in the communication element receiving slot 326B, the cover can be fastened to the opening of the communication element receiving slot 326B and cover the communication element 34B, thereby preventing the communication element 34B from falling out of the opening of the communication element receiving slot 326B.

[0103] In other possible embodiments, the mobile device accessory 3B may not include a cover, but instead has the communication element receiving slot 326B disposed on the rear side opposite the front side 321B. When the second connector 200A is retracted to the first position, the communication element 34B will be simultaneously held by the rear side of the latch body 32B and the back of the mobile device 2, thus preventing the communication element 34B from detaching from the mobile device accessory connector 1A. In some possible embodiments, the latch body 32B may also have communication element receiving slots 326B formed on both the front side 321B and the rear side, and the user can choose to configure different communication elements 34B in the communication element receiving slots 326B on the front side 321B and the rear side respectively, thereby enabling the mobile device accessory 3B to have a variety of different payment and sensing functions.

[0104] Please refer to Figure 7, which is a perspective view of the mobile device accessory connector in Figure 1 and the collaborative function of the mobile device and the mobile device accessory of the present invention in a third embodiment. The mobile device accessory 3C of this embodiment includes a latching member 31C, wherein the latching member 31C includes a latching body 32C and at least one connecting latching portion 33C. In this embodiment, the latching member 31C includes four connecting latching portions 33C, and these connecting latching portions 33C are engaging protrusions equally spaced along the circumference of the latching body 32C on the outer peripheral surface 323C of the latching body 32C. The main difference from the mobile device accessory 3A is that the mobile device accessory 3C also includes an accessory body 34C, wherein the accessory body 34C is connected to the latching member 31C and is a planar decorative piece.

[0105] In detail, although the main technical features of the accessories are all located on the latching member in the embodiments of mobile device accessories 3A and 3B, the present invention is not limited thereto. In this embodiment, mobile device accessory 3C also includes an accessory body 34C, wherein the accessory body 34C is, for example, a planar decorative piece or cover with an outer diameter substantially equal to that of the outer ring portion 110A, and the latching member 31C is disposed in the central part of the accessory body 34C, in this embodiment being an example of the two being fixed to each other. With this configuration, when the mobile device accessory 3C is latched to the second connector 200A through the connector latching part 33C, the accessory body 34C can completely cover the first connector 100A, thereby providing a different visual effect. In addition, various patterns, colors or favorite designs can be printed on the surface of the accessory body 34C away from the latching member 31C, thereby improving the aesthetic visual experience and the recognizability of the mobile device accessory 3C.

[0106] In some possible embodiments, the accessory body 34C can be made of a magnetic material such as a magnet. In this way, when the mobile device accessory 3C is engaged with the second connector 200A through the connector latching part 33C, the mobile device 2 can be magnetically fixed to the magnetic material structure of a refrigerator, blackboard or fitness equipment through the mobile device accessory connector 1A and the accessory body 34C, thereby improving the versatility of the mobile device 2 in use.

[0107] Please refer to Figure 8, which is a perspective view of the mobile device accessory connector in Figure 1 and the cooperative function of the mobile device and the mobile device accessory of the present invention in the fourth embodiment. The mobile device accessory 3D of this embodiment is generally similar to the mobile device accessory 3C of the third embodiment, including a latching member 31D and an accessory body 34D. The latching member 31D includes a latching body 32D and at least one connecting latching part 33D. In this embodiment, the latching member 31D includes four connecting latching parts 33D, and these connecting latching parts 33D are engaging protrusions that are equally spaced along the circumference of the latching body 32D on the outer peripheral surface 323D of the latching body 32D. The accessory body 34D is connected to the latching member 31D. The main difference from the mobile device accessory 3C is that the accessory body 34D is a card sleeve.

[0108] In detail, the accessory body 34D can be a card holder made of leather or plastic and has a card slot 346D. The card latch 31D is disposed on a connecting surface 342D of the accessory body 34D away from the card slot 346D. With this configuration, users can place cards such as ID cards, business cards, credit cards or EasyCards into the card slot 346D, and connect the accessory body 34D to the mobile device accessory connector 1A through the card latch part 33D. This allows users to simultaneously retrieve and carry the mobile device 2 and multiple cards, making it very convenient to use.

[0109] Please refer to Figure 9, which is a perspective view of the mobile device accessory connector in Figure 1 and the cooperative function of the mobile device and the fifth embodiment of the mobile device accessory of the present invention. The mobile device accessory 3E of this embodiment is generally similar to the mobile device accessory 3C of the third embodiment, including a latching member 31E and an accessory body 34E. The latching member 31E includes a latching body 32E and at least one connecting latching portion 33E. In this embodiment, the latching member 31E includes four connecting latching portions 33E, and these connecting latching portions 33E are engaging protrusions equally spaced along the circumference of the latching body 32E on the outer peripheral surface 323E of the latching body 32E. The accessory body 34E is connected to the latching member 31E. The main difference from the mobile device accessory 3C is that the accessory body 34E is a mobile power source.

[0110] In detail, the accessory body 34E can be a portable power bank suitable for providing power to the mobile device 2, and the latch 31E is disposed on a connecting surface 342E of the accessory body 34E. With this configuration, the user can simultaneously retrieve and carry the mobile device 2 and the mobile device accessory 3E including the power bank through the mobile device accessory connector 1A, thereby reducing the possibility of the mobile device 2 running out of power suddenly.

[0111] It is worth mentioning that in the embodiment of mobile device accessory 3D / mobile device accessory 3E, when the latching member 31D / latching member 31E and the second connector 200A are latched together, the connecting surface 342D / connecting surface 342E will adhere to the surface of the first connector 100A. That is, a gap is formed between the portion of the connecting surface 342D / connecting surface 342E covering the first connector 100A and the back of the mobile device 2, which facilitates the user to more easily extract the mobile device 2 or mobile device accessory 3D / mobile device accessory 3E. However, in some other embodiments, a connector clearance groove (not shown) with an outer diameter and depth corresponding to the outer ring portion 110A can also be formed on the connecting surface 342D / connecting surface 342E. Therefore, when the mobile device accessory 3D / mobile device accessory 3E is connected to the mobile device 2 or a mobile device housing containing the mobile device 2 via the mobile device accessory connector 1A, the first connector 100A and the second connector 200A can be fully accommodated within the connector clearance groove, and the connecting surface 342D / connecting surface 342E can directly abut against the back of the mobile device 2 or the mobile device housing. This improves the sealing between the mobile device accessory 3D / mobile device accessory 3E and the mobile device 2.

[0118] Please refer to Figures 13 and 14. Figure 13 is a perspective view of the second embodiment of the mobile device accessory connector of the present invention, showing its interaction with the mobile device accessory and an auxiliary accessory in Figure 3. Figure 14 is a perspective view of the mobile device accessory connector in Figure 13. The mobile device accessory connector 1B of this embodiment is generally similar to the mobile device accessory connector 1A, including a first connector 100B and a second connector 200B. The first connector 100B has at least one device engagement portion 120B disposed on an outer ring portion 110B, and the second connector 200B has a pivot portion 230B fixed to an inner ring portion 210B.

The main difference between the mobile device accessory connector 1B and the mobile device accessory connector 1A is that one of the first connector 100B and the second connector 200B may have at least one auxiliary accessory latching part, and the mobile device accessory connector 1B is adapted to be detachably latched to an auxiliary accessory 4 through the auxiliary accessory latching part.

[0120] For example, in this embodiment, the auxiliary accessory latching portion is provided on the first connector 100B. The first connector 100B in this embodiment may include four auxiliary accessory latching portions 140B, and these auxiliary accessory latching portions 140B are, for example, engaging grooves that are equally spaced along the inner circumference of the outer ring portion 110B. On the other hand, the auxiliary accessory 4 is, for example, a cover and includes an auxiliary accessory body 41 and at least one auxiliary connector latching portion 42. The auxiliary accessory body 41 has a front side 411 and an outer peripheral surface 413, and the auxiliary connector latching portions 42 are, for example, engaging protrusions whose number and shape correspond to the auxiliary accessory latching portions 140B and are equally spaced along the circumference of the auxiliary accessory body 41 on the outer peripheral surface 413. With this configuration, the user can simultaneously engage the auxiliary accessory 4 and the mobile device accessory 3A via the first connector 100B and the second connector 200B of the mobile device accessory connector 1B, and then magnetically fix it to the mobile device 2 via the device connection part 120B. Alternatively, with the first connector 100B already engaged with the mobile device 2, the auxiliary accessory 4 can be separately engaged and fixed to the first connector 100B. In other words, the mobile device accessory connector 1B of this embodiment provides the user with the ability to engage two different accessories simultaneously, without limiting the order of engagement or connection, thus providing greater flexibility in use.

[0121] It is worth mentioning that, in this embodiment, the engagement groove formed by the accessory latching portion 220B of the second connector 200B can be in the aforementioned form that is only open to the rear. This means that the second connector 200B needs to be unfolded to the second position relative to the first connector 100B in order to insert the mobile device accessory 3A into the engagement groove from the rear side of the inner ring portion 210B to complete the installation. Accordingly, when the second connector 200B is in the first closed position relative to the first connector 100B, this structural form can effectively prevent the mobile device accessory 3A from accidentally detaching.

[0122] On the other hand, in order to ensure that the auxiliary accessory 4 can smoothly engage with the first connector 100B without interfering with the second connector 200B, the second connector 200B in this embodiment can also have a clearance groove 250B on the outer periphery of the inner ring portion 210B. The second connector 200B in this embodiment is suitable for having the clearance groove 250B on the pivot portion 230B, but is not limited thereto. With this configuration, as shown in FIG14, when the second connector 200B is in the first closed position relative to the first connector 100B, the outer peripheral surface of the inner ring portion 210B is spaced apart from the inner peripheral surface of the outer ring portion 110B, and together with the clearance groove 250B, forms an annular groove, so that the auxiliary accessory 4 can smoothly pass through the outer peripheral surface 413 of the auxiliary accessory body 41, and be engaged by the auxiliary accessory locking portion 140B of the first connector 100B by the auxiliary connector locking portion 42.

[0123] Referring again to Figure 13, in some possible embodiments, the accessory latching part 220B can be moved to the first connector 100B, for example, to the outer peripheral surface of the outer ring 110B, and the mobile device accessory 3A has a corresponding latching structure, so that the first connector 100B can simultaneously engage with two different accessory latches, while the second connector 200B is used as a simple ring. Alternatively, the auxiliary accessory latching part 140B can be moved to the second connector 200B, for example, to the outer peripheral surface of the inner ring 210B, and the auxiliary accessory 4 has a corresponding latching structure, so that the second connector 200B can simultaneously engage with two different accessory latches.

[0124] Please refer to Figure 15, which is a cross-sectional view of the first connector along line BB in Figure 14. Similar to the accessory latching part 220A, in this embodiment, the auxiliary accessory latching part 140B is a latching groove and includes a pair of alignment grooves 142B and a locking groove 144B. The alignment groove 142B extends from the front side 111B of the outer ring part 110B along the axial direction D but does not reach the rear side 112B. The locking groove 144B is adjacent to and connected to the alignment groove 142B in the circumferential direction. The width of the locking groove 144B in the axial direction D is smaller than the width of the alignment groove 142B in the axial direction D. That is, the locking groove 144B does not communicate with the outside through the front side 111B or the rear side 112B. The entire latching groove is generally "└" shaped when viewed from the side. On the other hand, the circumferential length of the auxiliary connector locking part 42 is substantially equal to the circumferential length of the alignment groove 142B. Therefore, when the user wishes to lock the auxiliary accessory 4 and the first connector 100B together, the auxiliary connector locking part 42 can be aligned with the alignment groove 142B and inserted into the outer ring part 110B. After the auxiliary connector locking part 42 is inserted into the outer ring part 110B and aligned with the locking groove 144B, the auxiliary accessory body 41 is rotated circumferentially a certain distance, causing the auxiliary connector locking part 42 to be inserted into the locking groove 144B. This prevents the auxiliary accessory 4 and the first connector 100B from displacing relative to each other in the axial direction D and disengaging from the moving device accessory connector 1B. Preferably, the first connector 100B also has at least one auxiliary accessory positioning part 150B, which is, for example, a positioning protrusion, the number of which corresponds to the auxiliary connector locking parts 42 and is disposed within the engagement groove formed by the auxiliary accessory locking parts 140B. On the other hand, the auxiliary connector locking part 42 has a positioning feature corresponding to the auxiliary accessory positioning part 150B. In this embodiment, the positioning feature is a positioning recess. When the auxiliary connector locking part 42 is inserted into the locking groove 144B in the circumferential direction and rotated to a specific position, the auxiliary accessory positioning part 150B and the positioning feature lock together, thereby restricting the rotation of the auxiliary accessory 4 relative to the first connector 100B in the circumferential direction.

[0125] Please refer to Figure 16, which is a perspective view of the third embodiment of the mobile device accessory connector of the present invention, the first embodiment of the mobile device housing of the present invention, and a mobile device working together. The mobile device accessory connector 1C of this embodiment is generally similar to the mobile device accessory connector 1A of the first embodiment, including a first connector 100C and a second connector 200C. The first connector 100C includes an outer ring portion 110C and at least one device engagement portion 120C, with the device engagement portion 120C disposed on the outer ring portion 110C. The second connector 200C is pivotally connected to the outer ring portion 110C. The main difference from the mobile device accessory connector 1A is that the device engagement portion 120C is a snap-fit ​​protrusion, and the mobile device accessory connector 1C is adapted to work in conjunction with a mobile device housing 5A that houses the mobile device 2.

[0126] Specifically, the outer ring portion 110C has an outer peripheral surface, and the device engagement portion 120C is, for example, a snap-fit ​​protrusion disposed at equal intervals along the circumference of the outer ring portion 110C on the outer peripheral surface. On the other hand, the mobile device housing 5A of this embodiment includes a housing body 51A and a connector engagement portion 52A, wherein the housing body 51A is adapted to accommodate the mobile device 2; and the connector engagement portion 52A is disposed on the housing body 51A and adapted to be detachably engaged with the device engagement portion 120C of the mobile device accessory connector 1C.

[0127] Furthermore, the housing body 51A may have a back side, and the connector engagement portion 52A is, for example, a back plate with a connector receiving groove 526A and disposed on the back side of the housing body 51A. The connector receiving groove 526A is, for example, a through groove penetrating the back side of the housing body 51A, and engaging grooves of a shape and number corresponding to the device engagement portion 120C are formed on the groove wall. With this configuration, the user can first place the mobile device 2 inside the mobile device housing 5A, and then engage the first connector 100C with the connector engagement portion 52A through the device engagement portion 120C, so that the connector receiving groove 526A accommodates at least a portion of the first connector 100C and locks it in place. Therefore, the user can use the second connector 200C as a ring to retrieve the mobile device 2 and the mobile device housing 5A, making it convenient and easy to carry.

[0128] It is worth mentioning that, in some other embodiments, the device joint 120C can also be disposed on the second connector 200C. In this case, the connector receiving groove 526A can be designed as a groove corresponding to the size of the second connector 200C, thereby accommodating at least a portion of the second connector 200C.

[0129] Alternatively, in other embodiments, the connector engagement portion 52A, in addition to the connector receiving groove 526A, also forms an auxiliary receiving groove (not shown), and the auxiliary receiving groove is suitable for accommodating the other of the first connector 100C and the second connector 200C. With this configuration, the mobile device housing 5A can simultaneously accommodate at least a portion of the first connector 100C and the second connector 200C through the connector receiving groove 526A and the auxiliary receiving groove, respectively. The user can choose to use the first connector 100C or the second connector 200C as a ring according to their own needs, and use the other one to lock with the mobile device housing 5A.

[0130] Please refer to Figure 17, which is a perspective view of the second embodiment of the mobile device accessory connector in Figure 16 and the mobile device housing of the present invention, as well as the cooperative action of a mobile device. The mobile device housing 5B of this embodiment is generally similar to the mobile device housing 5A of the first embodiment, including a housing body 51B and a connector joint portion 52B. The housing body 51B is adapted to accommodate the mobile device 2, while the connector joint portion 52B is disposed on the back side of the housing body 51B and forms a connector receiving groove 526B. The main difference from the mobile device housing 5A is that the connector receiving groove 526B does not penetrate the back side of the housing body 51B.

[0131] In detail, in this embodiment, the connector receiving groove 526B is recessed only relative to the housing body 51B, and the depth of the connector receiving groove 526B is substantially equal to the thickness of the first connector 100C. With this configuration, when the user inserts the mobile device accessory connector 1C into the connector receiving groove 526B, the mobile device accessory connector 1C will not protrude from the mobile device housing 5B, and the user can unfold the second connector 200C to a second position to use it as a ring.

[0132] It should be noted that when the mobile device accessory connector 1C is inserted into the connector receiving groove 526B, the rear sides of the first connector 100C and the second connector 200C will adhere to the bottom of the groove wall of the connector receiving groove 526B. Therefore, in some possible embodiments, the device connecting portion 120C can be replaced with a magnet or adhesive foam, while the connector connecting portion 52B can be a corresponding magnetic component or adhesive surface, thereby engaging with the bottom of the groove wall of the connector receiving groove 526B. Alternatively, in addition to the snap-fit ​​relationship between the device connecting portion 120C and the periphery of the groove wall, additional fixing methods such as magnetic attraction or adhesion can be added to further increase the bonding strength between the mobile device accessory connector 1C and the mobile device housing 5B.

[0133] Please refer to Figure 18, which is a perspective view of the fourth embodiment of the mobile device accessory connector of the present invention. The mobile device accessory connector 1D of this embodiment is generally similar to the mobile device accessory connector 1B of the second embodiment, including a first connector 100D and a second connector 200D. The first connector 100D includes an outer ring portion 110D, at least one device engagement portion (not shown), a pivot member 130D, and at least one auxiliary accessory locking portion 140D. The outer ring portion 110D forms a first receiving hole 160D. The device engagement portion is, for example, a magnet and is disposed in the outer ring portion 110D. The pivot member 130D is connected to the outer ring portion 110D. The auxiliary accessory locking portion 140D is, for example, a plurality of engaging grooves disposed circumferentially on the inner circumferential surface of the outer ring portion 110D. On the other hand, the second connector 200D includes an inner ring portion 210D, at least one accessory latching portion 220D, and a pivot portion 230D, wherein the inner ring portion 210D surrounds a second receiving hole 260D; the accessory latching portion 220D is, for example, a plurality of engaging grooves arranged circumferentially on the inner peripheral surface of the inner ring portion 210D; and the pivot portion 230D is fixed to the outer peripheral surface of the inner ring portion 210D, and the first connector 100D and the second connector 200D are pivotally connected to each other through the pivot portion 130D and the pivot portion 230D. The main difference from the mobile device accessory connector 1B is that the first connector 100D also includes a stop portion 115D, wherein the stop portion 115D is disposed on the outer ring portion 110D and opposite to the pivot portion 230D.

[0134] In detail, the mobile device accessory connector 1D can limit the pivot phase or travel of the second connector 200D relative to the first connector 100D. As shown in FIG18, the stop portion 115D is, for example, a flat plate member disposed between the notches at both ends of the outer ring portion 110D, while the pivot member 130D is disposed on the radially outer side of the stop portion 115D and pivotally connected to the pivot portion 230D. With this configuration, when the second connector 200D is retracted to the first position relative to the first connector 100D, the pivot portion 230D will abut against the upper surface of the stop portion 115D, thus preventing the inner ring portion 210D from continuing to pivot towards the interior of the first receiving hole 160D, thereby achieving the effect of limiting the pivot phase or travel of the second connector 200D.

[0135] In addition, as shown in Figure 18, the accessory locking portion 220D can also include a pair of matching slots and a locking slot. In this embodiment, the locking slot can penetrate the inner ring portion 210D radially. Therefore, when the mobile device accessory connector 1D and the mobile device accessory 3A are locked together, a portion of the connector locking portion 33A can be extended or retracted, with a length greater than or equal to the radial width of the inner ring portion 210D. That is, in the extended state, a portion of the connector locking portion 33A can protrude relative to the inner ring portion 210D, thereby improving the stability of the locking mechanism.

[0136] Please refer to Figure 19, which is a perspective view showing the synergistic effect of the fifth embodiment of the mobile device accessory connector of the present invention and the ninth embodiment of the mobile device accessory of the present invention. The mobile device accessory connector 1E of this embodiment includes a connector 100E, wherein the connector 100E includes a connector body 110E, at least one device engaging portion 120E, and at least one accessory locking portion 140E. The connector body 110E forms a receiving hole 160E around the connector body. The device engaging portion 120E and the accessory locking portion 140E are disposed on the connector body 110E, and the mobile device accessory connector 1E can be detachably connected to the mobile device 2 and locked to a mobile device accessory 3I through the device engaging portion 120E and the accessory locking portion 140E, respectively.

[0137] Specifically, in this embodiment, the device coupling portion 120E is, for example, a C-shaped magnet, and the connector body 110E forms a magnet receiving groove 116E, and the device coupling portion 120E is disposed in the magnet receiving groove 116E; in addition, the accessory latching portion 140E is, for example, a plurality of latching grooves equally spaced along the circumference of the connector body 110E on the inner circumferential surface of the connector body 110E. On the other hand, the mobile device accessory 3I in this embodiment is, for example, a mobile power supply (or an external power supply) and includes a latching member 31I, an accessory body 34I, and a magnetic member 35I. The latching member 31I includes a latching body 32I and at least one connecting latching portion 33I. The latching body 32I is, for example, a disc with an outer diameter substantially the same as that of the receiving hole 160E. The connecting latching portion 33I is, for example, a latching protrusion. The number and shape of the protrusions correspond to the accessory latching portion 140E and are evenly spaced along the circumference of the latching body 32I on the outer peripheral surface 323I of the latching body 32I. The accessory body 34I is, for example, a disc with an outer diameter substantially the same as that of the connecting body 110E and is fixed to the latching body 32I. The magnetic member 35I is, for example, a C-shaped magnet with a shape and size corresponding to the device connecting portion 120E. With this configuration, when the user connects the mobile device 2 and the mobile device accessory 3I through the mobile device accessory connector 1E, the latching body 32I is embedded in the receiving hole 160E, and the accessory body 34I and the connector body 110E fit tightly and are flush with each other. The device connecting part 120E not only serves as a medium for the mobile device accessory connector 1E to be magnetically attracted to the mobile device 2, but also, in addition to the accessory latching part 140E and the connector latching part 33I being latched to each other, the magnetic attraction between the device connecting part 120E and the magnetic part 35I further enhances the bonding strength between the mobile device accessory connector 1E and the mobile device accessory 3I.

[0138] It is worth mentioning that, in other possible embodiments, the mobile device accessory 3I may not have a latching body 32I protruding from the end face of the accessory body 34I, while the connector latching part 33I may be provided on the end face of the accessory body 34I, and the connector latching part 33I may be a groove with the same shape and size as the connector body 110E. Accordingly, the connector latching part 33I can be embedded in the connector body 110E, and the connector latching part 33I can latch with the outer peripheral surface of the connector body 110E; or the magnetic member 35I can be fixed in the connector latching part 33I first and then embedded in the connector body 110E, and the connector body 110E and the mobile device accessory 3I can be firmly connected through the magnetic attraction between the device connecting part 120E and the magnetic member 35I. The present invention does not limit this.

[0139] Please refer to Figure 20, which is a perspective view of the mobile device accessory connector and an auxiliary connector working together as shown in Figure 19. As shown, in this embodiment, the mobile device accessory connector 1E further includes a pivot member 130E, wherein the pivot member 130E is pivotally connected to the connector body 110E and forms an insertion slot 136E, and the mobile device accessory connector 1E is adapted to be detachably connected to an auxiliary connector 200E through the pivot member 130E.

[0140] Specifically, the auxiliary connector 200E may include an auxiliary connector body 210E and a plug portion 230E. The auxiliary connector body 210E is generally annular and forms an auxiliary receiving hole 260E around it. The plug portion 230E is, for example, a protrusion with a hook at the tail and disposed on the outer peripheral surface 213E of the auxiliary connector body 210E. In this way, the user can pivot the pivot member 130E relative to the connector body 110E to a phase that is not parallel to the connector body 110E, and insert the auxiliary connector 200E into the insertion slot 136E of the pivot member 130E through the plug portion 230E for locking and fixing. Thus, while the connector 100E is connected to the mobile device 2 or the mobile device accessory 3I, the auxiliary connector 200E can also be used as a ring for extraction.

[0141] It is worth mentioning that, in the above embodiments having a first connector and a second connector, without causing structural contradictions or conceptual conflicts, the structural and technical features of each can be applied to the connector 100E and the auxiliary connector 200E; similarly, the technical feature that the auxiliary connector 200E can be pivotally connected to the connector body 110E through the plug-in portion 230E and the pivot portion 130E can also be applied to the above embodiments having a first connector and a second connector, and the present invention does not limit this.

[0142] Please refer to Figure 21, which is a perspective view showing the interaction between the mobile device accessory connector in Figure 19 and the tenth embodiment of the mobile device accessory of the present invention. As shown, the mobile device accessory 3J in this embodiment is, for example, a planar decorative piece and includes an accessory body 31J and a plug-in portion 32J. The accessory body 31J includes a front side surface 311J and an outer peripheral surface 313J, and the plug-in portion 32J is disposed on the outer peripheral surface 313J. Therefore, the user can configure colors, patterns, or various cute designs on the front side surface 311J of the mobile device accessory 3J, thereby improving the overall aesthetic appeal and recognizability of the mobile device accessory 3J when the connector 100E is combined with the mobile device 2 or the mobile device housing 5B.

[0143] Please refer to Figure 22, which is a perspective view showing the interaction between the mobile device accessory connector in Figure 19 and the eleventh embodiment of the mobile device accessory of the present invention. As shown, the mobile device accessory 3K in this embodiment is, for example, a three-dimensional decorative piece and includes an accessory body 31K and a plug-in portion 32K. The accessory body 31K includes a front side surface 311K and an outer peripheral surface 313K, and the plug-in portion 32K is disposed on the outer peripheral surface 313K. Therefore, the user can configure colors, patterns, or various cute designs on the front side surface 311K of the mobile device accessory 3K, thereby improving the overall aesthetic appeal and recognizability of the mobile device accessory 3J when the connector 100E is combined with the mobile device 2 or the mobile device housing 5B.

[0144] It should be noted that the terms "planar decorative parts" and "three-dimensional decorative parts" here refer to whether the front side of the accessory body protrudes relative to the connector body 110E when the insertion part 32J / 32K is inserted into the insertion slot 136E and the pivot part 130E pivots to a phase parallel to the connector body 110E. A planar decorative part is defined as one where the front side 311J of the accessory body 31J is recessed relative to or flush with the connector body 110E; conversely, a three-dimensional decorative part is defined as one where the front side 311K of the accessory body 31K protrudes relative to the connector body 110E.

[0145] Please refer to Figure 23, which is a perspective view of the sixth embodiment of the mobile device accessory connector of the present invention. The mobile device accessory connector 1F of this embodiment includes a first connector 100F and a second connector 200F, wherein the first connector 100F includes an outer ring portion 110F, at least one device engagement portion (not shown), and at least one auxiliary accessory locking portion 140F. The outer ring portion 110F surrounds a first receiving hole 160F. The device engagement portion is, for example, a magnet and is disposed on the outer ring portion 110F. The auxiliary accessory locking portion 140F is, for example, a plurality of engaging grooves equally spaced along the circumference of the outer ring portion 110F on the inner circumferential surface of the outer ring portion 110F. On the other hand, the second connector 200F includes an inner ring portion 210F, at least one accessory latching portion 220F, and a plug-in portion 230F, wherein the inner ring portion 210F surrounds a second receiving hole 260F; the accessory latching portion 220F is, for example, a plurality of engaging protrusions equally spaced along the circumference of the inner ring portion 210F on the outer peripheral surface 213F of the inner ring portion 210F; and the plug-in portion 230F is disposed on the outer peripheral surface 213F. The main difference from the mobile device accessory connector of other embodiments is that a plurality of connector latching slots 118F are formed on the outer ring portion 110F, and the second connector 200F is adapted to be selectively inserted into one of these connector latching slots 118F through the plug-in portion 230F.

[0146] Specifically, in this embodiment, the plug-in portion 230F is retractable and is retracted into the outer peripheral surface 213F of the inner ring portion 210F, so that the second connector 200F can be disposed in a first position relative to the first connector 100F by being housed in the first receiving hole 160F; when the user wants to unfold the second connector 200F relative to the first connector 100F for use, the second connector 200F can be removed first, and the plug-in portion 230F can be extended out of the outer peripheral surface 213F of the inner ring portion 210F, and then the plug-in portion 230F can be inserted into one of the connector locking slots 118F. These connector slots 118F provide different insertion phases for the second connector 200F. As shown in the figure, when the insertion part 230F is inserted into the outermost connector slot 118F, the inner ring part 210F extends radially outward relative to the outer ring part 110F; when the insertion part 230F is inserted into the middle connector slot 118F, the inner ring part 210F is vertically positioned relative to the outer ring part 110F; and when the insertion part 230F is inserted into the innermost connector slot 118F, the inner ring part 210F extends radially inward relative to the outer ring part 110F. In this way, the user can insert the second connector 200F into different connector slots 118F to adjust the usage state and position of the second connector 200F relative to the first connector 100F.

[0147] It should be noted that although this embodiment uses three parallel locking grooves extending circumferentially along the outer ring portion 110F and distributed on the same side of the outer ring portion 110F as an example of connector locking groove 118F, the present invention is not limited to this. In other possible embodiments, connector locking grooves 118F can also be provided at 0 degrees, 90 degrees, 180 degrees and 270 degrees of the outer ring portion 110F, and the number of connector locking grooves 118F in each phase can also be one, two or more, which can also achieve the effect of adjusting the position of the second connector 200F.

[0148] In other possible embodiments, the plug-in portion 230F may not have a telescopic function, but instead, like the accessory latch portion 220F, is fixedly protruding from the outer peripheral surface 213F. In this way, the auxiliary accessory latch portion 140F of the mobile device accessory connector 1F in this embodiment can have an additional engaging groove disposed on the inner peripheral surface of the outer ring portion 110F for inserting the plug-in portion 230F. Preferably, the plug-in portion 230F and the accessory latch portion 220F are equally spaced along the circumference of the inner ring portion 210F, so that the plurality of engaging grooves are also equally spaced along the circumference of the outer ring portion 110G on the inner peripheral surface of the outer ring portion 110G. This allows the plug-in portion 230F and the accessory latch portion 220F to be aligned with any engaging groove for assembly, thereby improving the ease and efficiency of assembly.

[0149] It is worth mentioning that, in the figures of the aforementioned embodiments, although the first receiving hole of the first connector and the second receiving hole of the second connector are both in the form of through holes, as long as the mechanisms do not conflict, the first receiving hole and / or the second receiving hole in each embodiment can also be in the form of a groove instead of a through hole; and even if the second receiving hole of the second connector is not through, the user can still hold the mobile device by clamping the inner ring of the second connector between two fingers. Therefore, the form of the first receiving hole of the first connector and the second receiving hole of the second connector of the present invention is not limited to what is shown in the figures, and can be modified by those skilled in the art according to their needs.

[0150] The present invention has been disclosed above with reference to preferred embodiments. However, those skilled in the art should understand that the above embodiments are only used to describe the present invention and should not be construed as limiting the scope of the present invention. Furthermore, it should be noted that all variations and substitutions equivalent to the above embodiments should be considered to be covered within the scope of the present invention.
