[0046] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only intended to illustrate the present application and are not intended to limit the scope of the present application. Similarly, the following examples are only some examples of the present application and not all examples. All other examples obtained by those of ordinary skill in the art without creative work are intended to fall within the scope of protection of this application.

[0047] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] See also Figures 1 to 3 , Figure 1 This is a schematic structural diagram of a connecting device in one embodiment of the present application. Figure 2 yes Figure 1 A schematic diagram of a partial structure of a socket in the embodiment, Figure 3 yes Figure 1 Schematic diagram of the overall structure of the plug in the embodiment.

[0049] An embodiment of the present application provides a connection device, including a plug 100 and a socket 200. The plug 100 includes a shell 11 and a first connector 18. The shell 11 includes a front end 111 and a rear end 112. The first connector 18 is arranged at the front end 111 of the shell 11; the socket 200 includes a plug-in box 21 and a second connector 23. The second connector 23 is arranged in the plug-in box 21. A slot 211 is provided on the plug-in box 21. The front end 111 of the shell 11 can be inserted into the plug-in box 21 through the slot 211 to connect the first connector 18 to the second connector 23.

[0050] See also Figure 4 as well as Figure 5 , Figure 4 yes Figure 3 A partial cross-sectional diagram of the plug in the embodiment, Figure 5 yes Figure 3 A schematic diagram of a partial structure of a plug in the embodiment, Figure 4 The Z direction represents the first direction, and the Y direction represents the second direction.

[0051] The plug 100 also includes a first clip 12 and a second clip 13 disposed at the front end 111 of the housing 11. The first clip 12 is connected to the housing 11 so as to be relatively movable along a first direction. A first elastic member 15 is disposed within the housing 11, elastically connecting the housing 11 and the first clip 12. The second clip 13 is disposed at the front end 111 of the housing 11 and is connected to the housing 11 so as to be relatively movable along a second direction, which intersects the first direction. A second elastic member 16 is disposed within the housing 11, elastically connecting the housing 11 and the second clip 13.

[0052] See also Figure 6 , Figure 6 yes Figure 3 A schematic diagram of the partial structure of the plug in the embodiment from another perspective. The first clip 12 has a first engaging portion 123 on the end facing the second clip 13, and the second clip 13 has a second engaging portion 133 on the end facing the first clip 12. The first engaging portion 123 and the second engaging portion 133 slidably engage with each other, allowing the first and second clips 12, 13 to be synchronously extended or retracted relative to the housing 11. When the front end 111 of the housing 11 is inserted into the plug-in compartment 21, the first and second clips 12, 13 engage against the inner wall of the plug-in compartment 21, preventing the plug 100 from falling out.

[0053] Optionally, combine Figure 2 as well as Figure 6 A card slot 213 is provided in the plug-in box 21, and the card slot 213 is located at the periphery of the slot 211. The first card connector 12 and the second card connector 13 are clamped in the card slot 213. The card slot 213 is clearance-matched with the first card connector 12 and the second card connector 13, which can further improve the stability of the connection between the plug 100 and the socket 200.

[0054] See also Figure 3 as well as Figure 6A pressing member 14 is movably provided on the housing 11 along a first direction, and the pressing member 14 is fixedly connected to the first clip 12. Operating the pressing member 14 can push the first clip 12 to retract relative to the housing 11 along the first direction and force the first elastic member 15 to deform, while the second elastic member 16 drives the second clip 13 to retract relative to the housing 11 along the second direction. When the pressing member 14 is released, the first clip 12 is reset to abut against the inner wall of the socket 200 under the action of the first elastic member 15, and the first mating portion 123 squeezes the second mating portion 133, causing the second clip 13 to extend relative to the housing 11 until it abuts against the inner wall of the socket 200, forcing the second elastic member 16 to deform. The pressing member 14 is located at the rear end 112 of the shell 11. After the front end 111 of the shell 11 is inserted into the plug-in box 21, the pressing member 14 at the rear end 112 can be operated to drive the first clip 12 at the front end 111 to be retracted into the shell 11. The first matching portion 123 and the second matching portion 133 slide relative to each other, so that the second clip 13 is simultaneously retracted into the shell 11, and the front end 111 of the plug 100 can be pulled out of the plug-in box 21, so that the plug 100 is separated from the socket 200.

[0055] It should be noted that the elastic force of the first elastic member 15 is greater than the elastic force of the second elastic member 16. Therefore, the first clip 12 can remain extended from the housing 11 under the action of the first elastic member 15, and can be retracted into the housing 11 under the action of an external force, overcoming the elastic force of the first elastic member 15. The first clip 12 transmits the supporting force of the first elastic member 15 to the second clip 13 via the first mating portion 123 and the second mating portion 133, allowing the second clip 13 to remain extended from the housing 11, overcoming the force of the second elastic member 16, and then being retracted into the housing 11 simultaneously under the action of the second elastic member 16 after the first clip 12 is retracted into the housing 11.

[0056] Please combine Figure 2 as well as Figure 3 In this embodiment, by providing a first clip 12 and a second clip 13 at the front end 111 of the housing 11, the first clip 12 and the second clip 13 can extend into the plug-in compartment 21 and abut against the inner wall of the plug-in compartment 21, thereby preventing the plug 100 from falling out and improving the stability of the connection between the plug 100 and the receptacle 200. Furthermore, the first clip 12 and the second clip 13 can block the gap between the slot 211 and the housing 11, thereby reducing the ingress of dust and other impurities into the plug-in compartment 21. By providing a pressing member 14 at the rear end 112 of the housing 11, when it is necessary to separate the plug 100 from the receptacle 200, pressure can be applied to the pressing member 14 to retract the first clip 12 into the housing 11. Simultaneously, the second clip 13, pushed by the first clip 12, retracts into the housing 11, allowing the front end 111 of the plug 100 to be removed from the plug-in compartment 21 of the receptacle 200.

[0057] See also Figure 5 , Figure 5 The dashed line F1 in the figure represents the first central axis, and the dashed line F2 represents the second central axis. In some embodiments, the first mating portion 123 includes a first inclined surface 1231, and the second mating portion 133 includes a second inclined surface 1331. The first inclined surface 1231 and the second inclined surface 1331 are parallel to each other and intersect with the first direction and the second direction. The first inclined surface 1231 and the second inclined surface 1331 can slide relative to each other and change the overlapping area between them. When the first inclined surface 1231 and the second inclined surface 1331 slide until the overlapping area gradually decreases, the first clamping member 12 and the second clamping member 13 extend relative to the housing 11. When the first inclined surface 1231 and the second inclined surface 1331 slide until the overlapping area gradually increases, the first clamping member 12 and the second clamping member 13 retract relative to the housing 11.

[0058] The housing 11 includes a first central axis parallel to the first direction, and the distances from the first inclined surface 1231 and the second inclined surface 1331 to the first central axis gradually decrease along the direction in which the first clamping member 12 extends out of the housing 11 .

[0059] By providing the first inclined surface 1231 and the second inclined surface 1331 , the second clamping member 13 can be linked with the first clamping member 12 , and the first clamping member 12 and the second clamping member 13 can be synchronously extended or retracted relative to the housing 11 without applying additional force to the second clamping member 13 .

[0060] In some embodiments, the first direction is perpendicular to the second direction, the first matching portion 123 also includes a first straight surface 1232 connected to the first inclined surface 1231, and the second matching portion 133 also includes a second straight surface 1332 connected to the second inclined surface 1331. The first straight surface 1232 and the second straight surface 1332 are parallel to the first direction. When the first clamping member 12 and the second clamping member 13 are extended to the maximum distance relative to the shell 11, the first straight surface 1232 abuts against the second straight surface 1332.

[0061] By providing the first straight surface 1232 and the second straight surface 1332 parallel to the first direction, after the external pressing force is lost, the first clip 12 and the second clip 13 can extend relative to the housing 11 until the first straight surface 1232 and the second straight surface 1332 abut against each other. The first clip 12 can then provide the second clip 13 with a stable supporting force perpendicular to the first straight surface 1232 and the second straight surface 1332, that is, a supporting force in the direction in which the second clip 13 extends out of the housing 11. In this way, even if the end of the second clip 13 extending out of the housing 11 is subjected to a force in the direction in which the second clip 13 is retracted into the housing 11, the first straight surface 1232 can still support the second clip 13 and keep it extending out of the housing 11.

[0062] In this embodiment, the first direction and the second direction form a 90° angle, the first inclined surface 1231 forms a 45° angle with both the first and second directions, and the second inclined surface 1331 forms a 45° angle with both the first and second directions. In other embodiments, the first and second directions may also form other angles, as long as the first inclined surface 1231 and the second inclined surface 1331 intersect with the first and second directions, so that the first inclined surface 1231 and the second inclined surface 1331 have components of movement along the first and second directions during the sliding engagement process.

[0063] In some embodiments, there are two first clips 12 relatively arranged, and the two first clips 12 are symmetrically arranged about the second central axis, and the two first clips 12 can be relatively close to or away from each other along the first direction; there are two first elastic members 15, and the two first elastic members 15 are symmetrically arranged about the second central axis, and each first elastic member 15 is connected to the shell 11 and one of the first clips 12.

[0064] Two second clips 13 are relatively arranged, and the two second clips 13 are symmetrically arranged about the first central axis. The two second clips 13 can be relatively close to or away from each other along the second direction; there are four second elastic members 16, and the four second elastic members 16 are symmetrically arranged into two groups about the first central axis. The two second elastic members 16 in any group are connected to the shell 11 and one of the second clips 13, and any two second elastic members 16 symmetrical about the second central axis can be deformed under the extrusion of one of the first clips 12.

[0065] See also Figure 4 as well as Figure 5In some embodiments, the first clamping member 12 is L-shaped and includes a first clamping plate 121 and a connecting plate 122 connected to the first clamping plate 121. The pressing member 14 is fixedly connected to the end of the connecting plate away from the first clamping plate 121. The first clamping plate 121 is fixedly connected to the side of the connecting plate 122 facing away from the first elastic member 15, and the first mating portion 123 is fixedly connected to the side of the connecting plate 122 facing the first elastic member 15. The two ends of the first elastic member 15 respectively abut against the connecting plate 122 and the housing 11. The connecting plate 122 connects the first clamping plate 121 at the front end 111 and the pressing member 14 at the rear end 112, thereby enabling the first clamping plate 121 and the pressing member 14 to be linked. The first elastic member 15 always remains in a compressed state, that is, the first elastic member 15 always provides a holding force to the first pressing member 14. In the absence of external force, the pressing member 14 is supported by the first elastic member 15 and drives the first clamping plate 121 to extend out of the housing 11. When the user applies pressure to the pressing member 14, the pressing member 14 can overcome the force of the first elastic member 15 and thus drive the first clamping plate 121 to retract into the housing 11. It is understandable that an escape hole is provided on the housing 11 for the user to apply force to the pressing member 14, so that the pressing surface of the pressing member 14 always remains exposed. This makes it convenient for the user to apply force to the pressing member 14 to drive the first clamping member 12 to move after the front end 111 of the plug 100 is inserted into the plug-in box 21, that is, after the first clamping member 12 and the second clamping member 13 are inserted into the plug-in box 21.

[0066] See also Figure 6 as well as Figure 7 , Figure 7 yes Figure 3 A schematic diagram of the partial structure of the plug in another embodiment from another perspective. In some embodiments, a partition 113 is connected to the housing 11 and disposed between the two first clamping members 12. The plane of the partition 113 coincides with the second central axis and is perpendicular to the first direction. Two first elastic members 15 are spaced apart and aligned, with each first elastic member 15 abutting against the first clamping member 12 and the partition 113 at both ends.

[0067] Please continue reading Figure 6 as well as Figure 7In some embodiments, the second clamping member 13 includes a second clamping plate 131 and a slider 132. The second clamping plate 131 is fixedly connected to the side of the slider 132 facing the second elastic member 16, and the second matching portion 133 is fixedly connected to the side of the slider 132 facing away from the second elastic member 16. The two ends of the second elastic member 16 are respectively in contact with the slider 132 and the inner wall of the shell 11. A guide member 114 is fixedly provided in the shell 11 along the second direction, and the slider 132 slides with the guide member 114. In this embodiment, the second elastic member 16 always remains in a compressed state, and the second elastic member 16 provides a force to retract the second clamping member 13 relative to the shell 11 along the second direction. In this way, the second clamping member 13 can extend out of the shell 11 under the push of the first clamping member 12, and automatically retract into the shell 11 after losing the push of the first clamping member 12.

[0068] In some embodiments, the two ends of the second elastic member 16 can be fixedly connected to the sliders 132 of the two sets of second clipping members 13, and the second elastic member 16 is always maintained in a stretched state. In other words, the two ends of the second elastic member 16 respectively provide pulling force to the two sets of second clipping members 13. In this way, after the two second clipping members 13 lose the push of the first clipping member 12, the two sets of second clipping members 13 can move closer to each other and retract into the interior of the housing 11 under the action of the second elastic member 16.

[0069] The first elastic member 15 and the second elastic member 16 include but are not limited to springs, springs, etc.

[0070] See also Figure 2 as well as Figure 3 In some embodiments, a baffle 19 is provided around the housing 11. When the plug 100 and the receptacle 200 are connected, the baffle 19 abuts against the outer wall of the receptacle 200 and covers the slot 211. The baffle 19 is located on the side of the first card board 121 facing away from the first connector 18. A plugging distance is defined between the baffle 19 and the first card board. This plugging distance matches the depth of the slot 211, so that the first card board 121 passes through the slot 211 and is inserted into the card cage 21, abutting against the inner wall of the card cage 21, while the baffle 19 abuts against the outer wall of the card cage 21.

[0071] Furthermore, a seal is provided on the side of the baffle 19 facing the first connector 18. The seal 17 is tightly attached to the outer walls of the baffle 19 and the socket 200 when the plug 100 and the socket 200 are connected. Optionally, the seal 17 can be a sealing gasket, which is annular and surrounds the slot 211 within it. The sealing gasket is tightly attached to the opposite sides of the baffle 19 and the plug-in box 21. Optionally, the seal 17 is a raised sealing ring, and a sealing groove 212 is provided around the slot 211. When the plug 100 and the socket 200 are connected, the seal 17 is embedded in the sealing groove 212 to achieve a seal around the periphery of the slot 211. The seal 17 can be made of silicone material with good sealing properties to prevent impurities, water vapor, etc. from entering the plug-in box 21.

[0072] Please combine Figure 2 as well as Figure 8 , Figure 8 yes Figure 2 Schematic diagram of the structure of the dustproof plate in an embodiment. In some embodiments, a dustproof plate 221 is rotatably provided within the plug-in box 21. During the connection process between the plug 100 and the receptacle 200, the dustproof plate 221 can rotate forward under the push of the front end 111 of the housing 11 to open the slot 211, allowing the front end 111 of the housing 11 to be inserted into the plug-in box 21. After the plug 100 and the receptacle 200 are separated, the dustproof plate 221 can rotate backward to cover the slot 211.

[0073] Optionally, a dust shield 221 is connected above the slot 211. Forward rotation refers to the upward rotation of the dust shield 221, while reverse rotation refers to the downward rotation of the dust shield 221. After the plug 100 is separated from the socket 200, the dust shield 221 can rotate downward due to gravity and cover the slot 211. Specifically, a mounting seat 222 is fixedly provided in the plug-in box 21. The mounting seat 222 is located above the slot 211. A rotating shaft is fixedly provided in the mounting seat 222. A roller shaft 223 is sleeved on the rotating shaft. The roller shaft 223 is rotatably connected to the rotating shaft, and the dust shield 221 is fixedly connected to the roller shaft 223.

[0074] Optionally, the plug-in box 21 is provided with two second connectors 23, and two corresponding slots 211 and dust shields 221 are also provided. The plug-in box 21 includes a first side panel 214, and both slots 211 extend through the first side panel 214. A mounting base 222 is fixed to the first side panel 214. The two dust shields 221 are connected to the same rotating shaft via rollers 223. The mounting base 222 includes a stopper 2221 disposed between the two dust shields 221 to prevent the two dust shields 221 from moving relative to each other along the axial direction of the rotating shaft.

[0075] The mounting base further includes a limiting surface 2222 for limiting the rotation range of the dustproof plate 221. The limiting surface 2222 forms a 90-degree angle with the first side plate 214, and the dustproof plate 221 is configured to rotate between the first side plate 214 and the limiting surface 2222.

[0076] See also Figure 9 , Figure 9 yes Figure 2 Schematic diagram of a partial structure of the second connector in an embodiment. In some embodiments, the second connector 23 includes a connection box 231, an elastic contact piece 232, and a conductive pin 233. The connection box 231 is fixedly connected to the plug-in box 21 at a position corresponding to the slot 211. The connection box 231 has an opening on the side facing the slot 211. The elastic contact piece 232 is provided on the side of the connection box 231 opposite the slot 211. The conductive pin 233 is connected to the elastic contact piece 232 and extends along the depth direction of the slot 211. The conductive pin 233 can be inserted into the first connector 18 to achieve an electrical connection between the first connector 18 and the second connector 23. The provision of the conductive pin 233 increases the contact area between the first connector 18 and the second connector 23, further improving the stability of the connection between the first connector 18 and the second connector 23. The provision of the elastic contact piece 232 can prevent the conductive pin 233 from being damaged by hard contact when the first connector 18 and the second connector 23 are connected.
