In this way, when the plug 2 is plugged into the socket 1, the first electrical connector 12 can be electrically connected to the second electrical connector 23, so that data or electric energy can be transmitted; at the same time, the first limiting structure can be connected to the buckle 25, so that the connection stability between the plug 2 and the socket 1 can be improved. In addition, since a button 26 is provided, the limiting of the buckle 25 by the first limiting structure can be released by pressing the button 26, so that the plug 2 can be easily pulled out of the socket 1, effectively avoiding the problem of damage to the plug 2 and / or the socket 1 when the operation is improper.

[0034] It should be noted that the drawings of the present application only show that the buckle 25 is provided on the plug 2, and correspondingly, the first limiting structure is provided on the socket 1. In actual applications, those skilled in the art may also provide the buckle 25 on the socket 1, and correspondingly, the first limiting structure is provided on the plug 2. This is not limited here, and those skilled in the art may make adjustments according to actual conditions. In addition, the first limiting structure of the embodiment of the present application includes but is not limited to a protrusion convexly provided on the plug 2 or the socket 1, and a card slot 141 concavely provided on the plug 2 or the socket 1.

[0035] In one embodiment, the plug 2 is provided with a buckle 25, and the socket 1 is provided with a first limiting structure, and the first limiting structure includes a protrusion convexly provided on the socket 1 or a slot 141 concavely provided on the socket 1. In this way, the plug 2 and the socket 1 can be reliably connected through the matching connection of the buckle 25 and the protrusion, or the buckle 25 and the slot 141.

[0036] It should be noted that the drawings of the present application only show the case where the first limiting structure is the card slot 141. In actual applications, those skilled in the art may also use the protrusion as the first limiting structure. This is not limited here, and those skilled in the art may make a choice according to actual needs.

[0037] In some optional embodiments of the present application, the socket 1 includes a boss 11 and an annular groove 14 arranged around the boss 11, a first limiting structure is arranged on the annular groove 14, and a first electrical connector 12 is arranged on the boss 11; the plug 2 has a mounting seat 22 for mounting a second electrical connector 23, and when the plug 2 is mated with the socket 1, the boss 11 abuts against the mounting seat 22 to electrically connect the second electrical connector 23 to the first electrical connector 12, and the buckle 25 is engaged with the first limiting structure.

[0038] In the embodiment of the present application, since the boss 11 and the mounting seat 22 are provided, the first electrical connector 12 is provided on the boss 11, and the second electrical connector 23 is provided on the mounting seat 22. In this way, when the plug 2 is plugged into the socket 1, the boss 11 can abut against the mounting seat 22, thereby realizing the electrical connection between the first electrical connector 12 and the second electrical connector 23. This electrical connection method is simple and reliable, and is conducive to the reliable transmission of data or electric energy. At the same time, since the first limiting structure provided on the boss 11 can be engaged with the buckle 25, it can prevent the plug 2 from being pulled out by mistake, thereby improving the reliability of data or electric energy transmission.

[0039] In a specific application, a plurality of the first electrical connector 12 and the second electrical connector 23 may be provided, and the first electrical connector 12 and the second electrical connector 23 are in electrical contact one by one. The first electrical connector 12 and the second electrical connector 23 may be a pogo pin connector or a metal connector (PAD). It is understood that when at least one of the first electrical connector 12 and the second electrical connector 23 is a pogo pin connector, since the pogo pin connector has a retractable feature, when the plug 2 is lifted relative to the socket 1, the first electrical connector 12 and the second electrical connector 23 can maintain electrical contact through its own retraction, which is beneficial to improve the reliability of the electrical connection between the plug 2 and the socket 1. In one embodiment, six first electrical connectors 12 and six second electrical connectors 23 are provided, and one first electrical connector 12 is in electrical contact with one second electrical connector 23, wherein the first electrical connector 12 is a metal connector and the second electrical connector 23 is a pogo pin connector.

[0040] In some optional embodiments of the present application, the first limiting structure is a slot 141, and the plug 2 and the socket 1 are detachably connected to the slot 141 through a buckle 25; the slot 141 is arranged on the groove wall of the annular groove 14; the plug 2 has an opening at a corresponding position of the slot 141; when the socket 1 and the plug 2 are mated and plugged in, at least part of the buckle 25 extends out relative to the opening, and the buckle 25 is engaged with the slot 141; the button 26 is used to push the buckle 25 to move, and by pressing the button 26, at least part of the buckle 25 retracts relative to the opening to release the limiting effect of the slot 141 on the buckle 25.

[0041] In the embodiment of the present application, the groove wall of the annular groove 14 of the socket 1 is provided with a slot 141; the plug 2 is provided with an opening at a position corresponding to the slot 141. Thus, when the plug 2 is plugged into the socket 1, at least a portion of the buckle 25 extends relative to the opening, so that the buckle 25 is engaged with the slot 141, thereby realizing a reliable connection between the plug 2 and the socket 1. When the plug 2 needs to be unplugged, the buckle 25 can be pushed to move by pressing the button 26, so that at least a portion of the buckle 25 is retracted relative to the opening, thereby releasing the limit of the buckle 25 by the slot 141, so that the plug 2 can be smoothly unplugged from the socket 1.

[0042] In some optional embodiments of the present application, the plug 2 includes a connection groove 21, the connection groove 21 is used to accommodate the buckle 25, and the connection groove 21 includes a first groove 211 and a second groove 212 that are connected to each other; the buckle 25 is arranged in the second groove 212 and at least partially extends into the first groove 211; the button 26 is arranged in the first groove 211 and connected to the buckle 25. Specifically, when the first limiting structure is the clamping groove 141, the buckle 25 is provided with a protruding clamping portion 251 at a position corresponding to the clamping groove 141, and the clamping portion 251 is used to clamp with the clamping groove 141.

[0043] In the embodiment of the present application, a connection groove 21 is provided to accommodate the buckle 25, wherein the connection groove 21 includes a first groove 211 and a second groove 212 that are interconnected. By arranging the buckle 25 in the second groove 212, a space for movement of the buckle 25 can be provided to avoid interference between the buckle 25 and other components in the plug 2 during movement. In addition, by extending at least part of the buckle 25 to the first groove 211, it can be connected to the button 26 located in the first groove 211. When the button 26 is pressed, an external force can be transmitted to the buckle 25, so that the buckle 25 moves and gradually moves away from the slot 141, thereby releasing the first limiting structure from limiting the buckle 25.

[0044] In a specific application, the connection groove 21 also includes a third groove 213. Specifically, the plug 2 is provided with a third groove 213 recessed along the first direction X at a corresponding position of the mounting seat 22, and the third groove 213 is connected to the second groove 212. When the plug 2 is mated with the socket 1, the boss 11 is embedded in the third groove 213 and abuts against the mounting seat 22. On the one hand, the first electrical connector 12 can be electrically connected to the second electrical connector 23, and on the other hand, the clamping portion 251 of the buckle 25 located in the second groove 212 can be clamped with the clamping groove 141 located in the annular groove 14.

[0045] In some optional embodiments of the present application, the electrical connection structure also includes an elastic reset member 27, which is disposed between the button 26 and the buckle 25. When the button 26 is pressed, the button 26 squeezes the elastic reset member 27 and pushes the buckle 25 to move so as to release the limitation of the buckle 25 by the first limiting structure; or, the elastic reset member 27 is disposed between the button 26 and the first limiting structure. When the button 26 is pressed, the button 26 squeezes the elastic reset member 27 and pushes the first limiting structure to move so as to release the limitation of the buckle 25 by the first limiting structure; when the button 26 is released, the elastic reset member 27 pushes the button 26 to reset.

[0046] In the embodiment of the present application, an elastic reset member 27 is provided between the button 26 and the buckle 25, or between the button 26 and the first limiting structure. In this way, when the button 26 is pressed, the button 26 can squeeze the elastic reset member 27 and push the buckle 25 or the first limiting structure to move, so as to release the first limiting structure from limiting the buckle 25; at the same time, the elastic reset member 27 can store a certain amount of elastic potential energy. When the button 26 is released, the elastic reset member 27 generates a restoring force and pushes the buckle 25 or the first limiting structure to reset. That is, in the embodiment of the present application, the movement or reset of the buckle 25 or the first limiting structure can be achieved through the mutual cooperation of the button 26 and the elastic reset member 27, thereby achieving the connection or disconnection of the buckle 25 with the first limiting structure. It should be noted that the elastic reset member 27 refers to a structure that can store elastic potential energy and generate a restoring force when the external force disappears.

[0047] In some optional embodiments of the present application, the elastic reset member 27 is arranged in the first groove 211 and is respectively connected to the button 26 and the buckle 25. When the button 26 is pressed, the button 26 squeezes the elastic reset member 27 and pushes the buckle 25 to move to release the limitation of the buckle 25 by the first limiting structure.

[0048] In the embodiment of the present application, by connecting the elastic reset member 27 to the buckle 25, when the button 26 is pressed, the button 26 can squeeze the elastic reset member 27 and push the buckle 25 to move, thereby quickly releasing the first limiting structure from limiting the buckle 25. In this process, the elastic reset member 27 can store a certain amount of elastic potential energy. When the button 26 is released, the elastic reset member 27 generates a restoring force in the opposite direction of the push direction of the button 26 and transmits it to the buckle 25, thereby achieving the resetting of the buckle 25.

[0049] In some optional embodiments of the present application, the elastic return member 27 includes a sliding sleeve 272 and a spring 271; the spring 271 is arranged between the sliding sleeve 272 and the bottom wall of the first groove 211, and the two ends of the spring 271 are respectively abutted against the sliding sleeve 272 and the bottom wall of the first groove 211; the buckle 25 and the button 26 are fixedly connected to the end of the sliding sleeve 272 away from the spring 271 in sequence, and the buckle 25 is close to the sliding sleeve 272.

[0050] In the embodiment of the present application, since the spring 271 and the sliding sleeve 272 are provided, and the buckle 25, the button 26 and the sliding sleeve 272 are fixedly connected. In this way, when the button 26 is pressed, the button 26 can squeeze the spring 271 and push the sliding sleeve 272 to drive the buckle 25 to move along the second direction Y, thereby quickly releasing the first limiting structure, such as the limit of the buckle 25 by the slot 141. When the button 26 is released, the spring 271 generates a restoring force in the opposite direction to the pushing direction of the button 26, thereby pushing the sliding sleeve 272 to drive the buckle 25 to move along the second direction Y, thereby achieving the resetting of the buckle 25.

[0051] Specifically, by Figures 8 to 9 It can be seen that the first groove 211 is extended along the second direction Y, and the first groove 211 includes a sliding groove and a limiting groove sequentially arranged along the second direction Y, wherein the inner diameter of the limiting groove is larger than the inner diameter of the sliding groove; the elastic reset member 27 also includes a screw 273, and the sliding sleeve 272 is slidably connected to the sliding groove, wherein the sliding sleeve 272 has two ends that are separated from each other along the second direction Y, and a guide groove is provided at one end of the sliding sleeve 272 close to the spring 271, and the guide groove is used to accommodate at least part of the spring 271 and guide the spring 271 to extend and retract along the second direction Y; a fixing groove is provided at one end of the sliding sleeve 272 away from the spring 271, and the groove wall of the fixing groove is provided with a thread, and the screw 273 passes through the buckle 25 and is threadedly connected to the fixing groove, so that the buckle 25 is fixedly connected to the sliding sleeve 272, so that under the extension and retraction action of the spring 271, the sliding sleeve 272 slides relative to the sliding groove along the second direction Y, thereby driving the buckle 25 to extend or retract relative to the opening. The button 26 is fixedly connected to one end of the sliding sleeve 272 away from the sliding sleeve 272 by glue and the screw 273, and the button 26 is slidably connected to the limiting groove. By pressing the button 26, the sliding sleeve 272 can be moved toward the bottom of the sliding groove, so that at least part of the buckle 25 is retracted into the opening, thereby releasing the connection between the buckle 25 and the first limiting structure, such as the slot 141.

[0052] In a specific application, a limiting portion is usually provided at one end of the sliding sleeve 272 away from the spring 271, and the limiting portion can abut against the step surface formed by the sliding groove and the limiting groove, thereby limiting the compression stroke of the sliding sleeve 272 and further limiting the movement stroke of the buckle 25. Based on this, the buckle 25 is provided with a bent portion at a position corresponding to the edge of the limiting portion, so that the side of the buckle 25 away from the slot 141 can be flush with the side of the limiting portion close to the spring 271, thereby reducing the space required for the buckle 25 to move.

[0053] In some optional embodiments of the present application, the plug 2 also includes a second suction member 24, and the socket 1 also includes a first suction member 13. When the plug 2 is plugged into the socket 1, the second suction member 24 and the first suction member 13 are attracted to each other to limit the relative movement of the plug 2 and the socket 1.

[0054] In the embodiment of the present application, since the first suction member 13 and the second suction member 24 are respectively provided on the socket 1 and the plug 2, the mutual attraction of the first suction member 13 and the second suction member 24 can limit the relative movement of the plug 2 and the socket 1 after the plugging is completed, thereby avoiding the problem of poor contact or even disconnection of the electrical connection between the first electrical connection member 12 and the second electrical connection, which is beneficial to improving the connection reliability of the plug 2 and the socket 1.

[0055] It should be noted that one of the first attraction member 13 and the second attraction member 24 is a magnetic member (such as a magnet), and the other is a metal member (such as an iron block). The relative fixation of the plug 2 and the socket 1 can be achieved by the mutual attraction of the two magnetic members or the attraction of the magnetic member to the metal member. In one embodiment, the first attraction member 13 is a magnetic member, and the second attraction member 24 is a magnetic member; in another embodiment, the first attraction member 13 is a magnetic member, and the second attraction member 24 is a metal member. It can be understood that compared with the case where both the first attraction member 13 and the second attraction member 24 are magnetic members, when the first attraction member 13 is a magnetic member and the second attraction member 24 is a metal member, the cost of the entire electrical connection structure can be reduced.

[0056] It should be noted that the magnetic part can be a structure composed of one or more magnets, and the metal part can be a structure composed of one or more iron blocks, which is not limited here, and those skilled in the art can adjust according to actual needs. It is understandable that when a magnetic part composed of multiple magnets or a metal part composed of multiple iron blocks is provided, other parts of the plug 2 and the socket 1 can be avoided more flexibly.

[0057] In some optional embodiments of the present application, the socket 1 includes a boss 11 and an annular groove 14 arranged around the boss 11, the second suction member 24 is arranged in the circumference of the boss 11, and the first electrical connector 12 is arranged on the boss 11; the plug 2 has a mounting seat 22 for mounting the second electrical connector 23, and the first suction member 13 is arranged in the circumference of the mounting seat 22; when the plug 2 is mated with the socket 1, the boss 11 abuts against the mounting seat 22 to electrically connect the second electrical connector 23 to the first electrical connector 12, and the first suction member 13 and the second suction member 24 attract each other. In this way, by arranging the first suction member 13 on the circumference of the boss 11 and arranging the second suction member 24 on the circumference of the mounting seat 22, that is, when the plug 2 is mated with the socket 1, the entire circumference of the boss 11 and the mounting seat 22 is limited by the suction force, so that the boss 11 and the mounting seat 22 can be reliably abutted together, which is beneficial to improving the electrical connection reliability between the first electrical connector 12 and the second electrical connector 23.

[0058] In a specific application, the socket 1 includes a first shell 17, the first shell 17 is provided with an annular groove 14, the boss 11 is provided in the annular groove 14, the groove wall of the annular groove 14 and the side wall of the boss 11 enclose to form a roughly annular first suction member installation groove, the first suction member 13 is embedded in the first suction member installation groove, and the height of the first suction member 13 along the first direction X is less than the height of the boss 11 along the first direction X, so that the third groove 213 and the boss 11 are matched and plugged. The plug 2 includes a second shell 29 that is roughly T-shaped, and the second shell 29 is provided with a third groove 213 and a roughly annular second suction member installation groove at one end close to the socket 1, the second suction member installation groove is arranged in the circumference of the third groove 213, and the second suction member 24 is embedded in the second suction member installation groove.

[0059] In a specific application, the first shell 17 includes a first inner shell 171 and a first outer shell 172 which are arranged along the first direction X and connected to each other, wherein the first outer shell 172 is arranged close to the plug 2. The socket 1 also includes a base 16, which is arranged at one end of the boss 11 close to the first inner shell 171, and the base 16 is connected to the first outer shell 172 by screws. In addition, the base 16 can also carry the first suction member 13. A first circuit board 15 is arranged on the side of the base 16 away from the boss 11, and a first electrical connector 12 is arranged through the boss 11 and the base 16. The first electrical connector 12 has two ends arranged away from each other along the first direction X, and one end of the first electrical connector 12 close to the plug 2 is electrically connected to the second electrical connector 23, and one end of the first electrical connector 12 close to the first circuit board 15 is electrically connected to the first circuit board 15, and the first circuit board 15 is electrically connected to the electronic device, such as the motherboard of a head-mounted display device. A second circuit board 28 is disposed in the second housing 29 at a position corresponding to the second electrical connector 23, and an end of the second electrical connector 23 facing away from the socket 1 is electrically connected to the second circuit board 28. At least part of the cable 3 is disposed in the second housing 29, and the wire of the cable 3 is electrically connected to the second circuit board 28. Fig.10 As shown, when the end of the cable 3 facing away from the plug 2 is connected to an external power source or an external device, electrical energy or data can be transmitted and delivered to the mainboard of the head-mounted display device in sequence through the cable 3, the second circuit board 28, the second electrical connector 23, the first electrical connector 12, and the first circuit board 15, thereby realizing charging or data transmission of the head-mounted display device.

[0060] It should be noted that the first circuit board 15 and the second circuit board 28 can be a printed circuit board (PCB) or a flexible circuit board (FPC), which is not limited here, and those skilled in the art can choose according to actual needs. In one embodiment, in order to facilitate the processing of the electrical connection structure, the first circuit board 15 is a flexible circuit board and the second circuit board 28 is a printed circuit board.

[0061] In some optional embodiments of the present application, such as Figure 1 to Figure 2 As shown Figures 5 to 7, the plugging direction of the socket 1 and the plug 2 is the first direction X, the socket 1 includes a boss 11 protruding along the first direction X, and the first electrical connector 12 is arranged on the boss 11; the plug 2 has a mounting seat 22 for mounting the second electrical connector 23, and the plug 2 is provided with a third groove 213 recessed along the first direction X at a corresponding position of the mounting seat 22; when the plug 2 is matingly plugged with the socket 1, the boss 11 is embedded in the third groove 213 and abuts against the mounting seat 22 so that the second electrical connector 23 is electrically connected to the first electrical connector 12, wherein a first gap is provided between the boss 11 and the third groove 213; at least one first protruding portion 111 is provided on the outer periphery of the boss 11, and a first recessed portion 2131 is provided on the groove wall of the third groove 213 at a position corresponding to the boss 11, and a first protruding portion 111 is embedded in a first recessed portion 2131 and has a second gap with the first recessed portion 2131.

[0062] In practical applications, such as Figure 3 to Figure 4 As shown, when the cable 3 is pulled and the plug 2 is lifted relative to the socket 1, the third groove 213 will tilt and interfere with the boss 11, thereby limiting the further lifting of the plug 2. On the basis of the same first gap between the boss 11 and the third groove 213, taking two rectangular bosses (hereinafter referred to as the first boss and the second boss) as an example, the first boss and the second boss have different lengths, and the height and width are the same. Specifically, the height of the first boss is 3.0mm, the length is 7.0mm, and the first gap is 0.07mm; the height of the second boss is 3.0mm, the length is 1.5mm, and the first gap is 0.07mm. After testing, when the plug 2 is lifted relative to the socket 1 along the length direction of the rectangular boss, the lifting amount of the plug 2 relative to the socket 1 along the first direction X when the third groove 213 interferes with the first boss is 0.22mm, and the lifting amount of the plug 2 relative to the socket 1 along the first direction X when the third groove 213 interferes with the second boss is 0.08mm. It can be seen from this that when the plug 2 is lifted relative to the socket 1, for the boss 11 and the third groove 213 with a certain matching clearance, as the outer dimensions of the boss 11 increase, the amount of lift of the plug 2 also increases.

[0063] In the embodiment of the present application, since at least one first protrusion 111 is provided on the outer periphery of the boss 11, and the groove wall of the third groove 213 is correspondingly provided with a first recessed portion 2131, when the plug 2 is lifted relative to the socket 1, the first protrusion 111 and the first recessed portion 2131 may interfere with the boss 11 and the third groove 213 before the plug 2 is lifted further, thereby limiting the further lifting of the plug 2 and reducing the amount of lifting of the plug 2, thereby improving the electrical contact reliability of the first electrical connector 12 and the second electrical connector 23, which is beneficial to improving the user experience of using the head-mounted display device.

[0064] It should be noted that the drawings of the present application only show the situation that the boss 11 is arranged on the socket 1 and the third groove 213 is arranged on the plug 2. In actual applications, those skilled in the art may also arrange the boss 11 on the plug 2 and the third groove 213 on the socket 1, which is not limited here. The gap values ​​of the first gap and the second gap in the embodiment of the present application may be the same or different. It can be understood that when the gap values ​​of the first gap and the second gap are different, in order to further reduce the warping amount of the plug 2, the gap value of the second gap should be smaller than the gap value of the first gap. The embodiment of the present application does not limit the specific values ​​of the first gap and the second gap, and those skilled in the art may adjust them according to the specific dimensions of the boss 11 and the third groove 213 and the matching accuracy. In addition, the plug 2 and the socket 1 in the embodiment of the present application are both processed and formed by insert injection molding.

[0065] In some optional embodiments of the present application, a plurality of first protrusions 111 are provided, and the plurality of first protrusions 111 are arranged at circumferential intervals along the boss 11; a plurality of first recessed portions 2131 are provided, and the plurality of first recessed portions 2131 are arranged at circumferential intervals along the third groove 213, and the first protrusions 111 and the first recessed portions 2131 are correspondingly connected in a one-to-one manner.

[0066] In the embodiment of the present application, since the boss 11 is provided with a plurality of first protrusions 111 at circumferential intervals, correspondingly, the third groove 213 is provided with a plurality of first recessed portions 2131 at circumferential intervals. Through the one-to-one corresponding engagement connection between the first protrusions 111 and the first recessed portions 2131, the warping of the plug 2 in the entire circumferential direction can be restricted.

[0067] It should be noted that the plurality of first protrusions 111 can be arranged at uniform intervals along the circumference of the boss 11, or at non-uniform intervals. The embodiment of the present application does not limit this, and those skilled in the art can make adjustments according to actual needs. It is understandable that when the plurality of first protrusions 111 are arranged at uniform intervals along the circumference of the boss 11, on the one hand, the processing difficulty of the plug 2 and the socket 1 can be reduced; on the other hand, the entire circumference of the boss 11 can be restricted from warping, thereby limiting further warping of the plug 2 in any direction, which is conducive to improving the reliability of the electrical connection between the plug 2 and the socket 1, and improving the user's experience of using the head-mounted display device.

[0068] In some optional embodiments of the present application, two second recessed portions 112 are provided on both sides of the first protruding portion 111 along an extension direction perpendicular to the first protruding portion 111; the groove wall of the third groove 213 is provided with two second protruding portions 2132 at positions corresponding to the boss 11, and a second protruding portion 2132 is embedded in a second recessed portion 112 and has a third gap between the second protruding portion 2132 and the second recessed portion 112.

[0069] In the embodiment of the present application, since two second recessed portions 112 are provided on both sides of the first protruding portion 111, the size of the first protruding portion 111 along its extension direction can be increased, that is, when the plug 2 is lifted relative to the socket 1, the interference area between the first protruding portion 111 and the first recessed portion 2131 is increased, thereby reliably limiting further lifting of the plug 2, effectively reducing the amount of lifting of the plug 2, and improving the reliability of the electrical connection between the plug 2 and the socket 1.

[0070] It should be noted that the gap values ​​of the first gap and the third gap in the embodiment of the present application can be the same or different. It can be understood that when the gap values ​​of the first gap and the third gap are different, in order to further reduce the warping amount of the plug 2, the gap value of the third gap should be smaller than the gap value of the first gap. The embodiment of the present application does not limit the specific values ​​of the first gap and the third gap, and those skilled in the art can adjust them according to the specific dimensions and matching accuracy of the boss 11 and the third groove 213. In one embodiment, the gap values ​​of the first gap, the second gap and the third gap are the same, so that the processing difficulty of the electrical connection structure can be reduced.

[0071] In practical applications, the edges of the boss 11, the first raised portion 111, and the second raised portion 2132 are usually chamfered to avoid deformation of the boss 11, the first raised portion 111, and the second raised portion 2132 due to local stress concentration on the edges when the boss 11 and the third groove 213, the first raised portion 111 and the first recessed portion 2131, and the second raised portion 2132 and the second recessed portion 112 are matched, thereby affecting the plug-in reliability of the plug 2 and the socket 1.

[0072] like Fig.11 As shown, the boss 11 is a rectangular boss, the width direction of the boss 11 is the second direction Y, and the second direction Y is perpendicular to the first direction X; the boss 11 includes two first side walls 113 arranged opposite to each other along the second direction Y, and the first protrusions 111 are arranged on both first side walls 113.

[0073] In the embodiment of the present application, for the rectangular parallelepiped boss 11, when the plug 2 is lifted relative to the socket 1, the lift amount of the plug 2 along the width direction of the boss 11, that is, the second direction Y, is less than the lift amount of the plug 2 along the length direction of the boss 11, that is, the third direction Z. Based on this, the embodiment of the present application preferably provides a first protrusion 111 on the first side wall 113 of the boss 11 to reduce the lift amount of the plug 2 along the length direction of the boss 11, thereby improving the reliability of the electrical connection between the plug 2 and the socket 1 and reducing the processing costs of the plug 2 and the socket 1.

[0074] It should be noted that, for the rectangular parallelepiped boss 11, the height direction of the rectangular parallelepiped boss 11 is the first direction X, the width direction is the second direction Y, and the length direction is the third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In another embodiment, the rectangular parallelepiped boss 11 also includes two second side walls 114 arranged opposite to each other along the third direction Z, and the two first side walls 113 and the two second side walls 114 are both provided with a first protrusion 111, so that the warping of the rectangular parallelepiped boss 11 along multiple directions, such as the second direction Y and the third direction Z, can be limited. In addition, the boss 11 of the embodiment of the present application may also be other shapes, such as cylindrical, prismatic or other irregular shapes, which are not limited here. Those skilled in the art may set at least one first protrusion 111 on the circumference of the boss 11 according to actual needs to reduce the warping amount of the plug 2.

[0075] In some optional embodiments of the present application, two first protrusions 111 are provided, and the two first protrusions 111 are symmetrically arranged on the two first side walls 113. In this way, the structure of the plug 2 and the socket 1 can be further simplified, which is conducive to reducing the processing cost of the plug 2 and the socket 1.

[0076] It should be noted that the two first protrusions 111 can be symmetrically arranged at any position in the length direction of the two first side walls 113, and are not limited here. It can be understood that when the two first protrusions 111 are arranged in the center, the plug 2 can be inserted forward or backward for the rectangular boss, which can improve the plug-in freedom of the plug 2 and the socket 1. Among them, forward plug-in refers to the plug-in of the plug 2 and the socket 1 in alignment, and reverse plug-in refers to plugging the plug 2 with the socket 1 after rotating it 180°.

[0077] Combination Figures 5 to 7 , the following provides an example of the working process of the electrical connection structure of the embodiment of the present application:

[0078] 1. Insert the plug 2 into the socket 1: First, align the third groove 213 of the plug 2 with the boss 11 of the socket 1; secondly, press the plug 2 along the first direction X. During the pressing process, the buckle 25 is first squeezed by the groove wall of the annular groove 14 and retracts relative to the opening, and then extends relative to the opening under the action of the spring 271 and engages with the slot 141; at the same time, on the one hand, the boss 11 abuts against the mounting seat 22 to electrically connect the first electrical connector 12 and the second electrical connector 23; on the other hand, the second suction member 24 of the plug 2 is attracted to the first suction member 13 of the socket 1, and the reliable insertion of the plug 2 and the socket 1 is completed.

[0079] 2. Pulling the plug 2 out of the socket 1: Press the button 26 to retract the buckle 25 relative to the opening to release the connection between the buckle 25 and the slot 141 , so that the plug 2 can be smoothly pulled out of the socket 1 .

[0080] In summary, the electrical connection structure provided by the embodiment of the present application has at least the following advantages:

[0081] Since one of the plug and the socket is provided with a first limiting structure, and the other is provided with a buckle, when the plug and the socket are plugged in, the first electrical connector can be electrically connected to the second electrical connector, thereby realizing the transmission of data or electric energy; at the same time, the first limiting structure can be connected to the buckle, thereby improving the connection stability between the plug and the socket. In addition, since a button is provided, the limiting of the buckle by the first limiting structure can be released by pressing the button, thereby easily pulling the plug out of the socket, effectively avoiding the problem of damage to the plug and / or the socket due to improper operation.

[0082] An embodiment of the present application further provides an electronic device, the electronic device comprising the electrical connection structure of any one of the above embodiments.

[0083] In the embodiment of the present application, since the electronic device is provided with an electrical connection structure, specifically, the socket 1 of the electrical connection structure is provided on the electronic device, and the plug 2 is connected to an external power source or an external device through a cable 3, the transmission of electric energy or data can be achieved through the plugging of the socket 1 and the plug 2, that is, the plugging of the boss 11 and the third groove 213. Since at least one first protrusion 111 is provided on the periphery of the boss 11, and at least one first recess 2131 is correspondingly provided on the groove wall of the third groove 213, when the cable 3 is pulled and causes the plug 2 to be lifted relative to the socket 1, the first protrusion 111 and the first recess 2131 can interfere first, thereby reducing the lifting amount of the plug 2, improving the reliability of the electrical connection between the plug 2 and the socket 1, and facilitating the transmission reliability of electric energy or data of the electronic device.
