Description

Technical Field

[0001] The present application relates to the technical field of plugs, and in particular to a male plug, a female plug, and a connecting mechanism. Background Art

[0002] With the development of intelligent, integrated and miniaturized electronic devices, a single electronic device can usually realize multiple functions. Among them, the plug, as an indispensable accessory of the electronic device, also needs to be equipped with a large number of pins to realize the corresponding power and data transmission.

[0003] However, in the prior art, as the number of pins increases, the cross-sectional area of ​​the plug also increases, resulting in a continuous increase in occupied area and affecting the arrangement of surrounding electrical components. Summary of the Invention

[0004] The present application provides a male plug, a female plug and a connecting mechanism to reduce occupied area.

[0005] In a first aspect, the present application provides:

[0006] A male plug, comprising:

[0007] A first base body, used for plugging and connecting with a female plug, wherein the first base body includes a first side wall circumferentially arranged around the first base body; and

[0008] A plurality of first terminals are at least arranged on the first side wall, and the first terminals are used for electrically connecting to a female plug.

[0009] In some possible implementations, the male plug further includes a first fool-proof component, and the first fool-proof component is used for fool-proof connection between the male plug and the female plug.

[0010] In some possible implementations, the first foolproof component includes:

[0011] a first guide member, disposed on the first side wall; or

[0012] A plurality of first guide members are disposed on the first side wall, and the plurality of first guide members are distributed in a non-rotationally symmetrical manner around the axis of the first base.

[0013] In a second aspect, the present application provides a female plug, comprising:

[0014] A second base body includes an inserting groove for inserting and connecting with a male plug, wherein the inserting groove includes a second side wall arranged around the axis of the second base body; and

[0015] A plurality of second terminals are at least arranged on the second side wall, and the second terminals are used for electrically connecting to the male plug.

[0016] In some possible implementations, the female plug further includes a second fool-proof component, and the second fool-proof component is used for fool-proof connection between the female plug and the male plug.

[0017] In some possible implementations, the second foolproof component includes:

[0018] a second guide member disposed on the second side wall; or

[0019] A plurality of second guide members are disposed on the second side wall, and the plurality of second guide members are distributed in a non-rotationally symmetrical manner around the axis of the second base.

[0020] In some possible implementations, the second guide member includes a first guide groove and a second guide groove;

[0021] wherein the first guide groove extends along the axis of the second base body;

[0022] One end of the second guide groove is connected to one end of the first guide groove, and the second guide groove extends along the circumference of the second base body.

[0023] In some possible implementations, the female plug further includes an elastic locking member, which is disposed at an end of the second guide groove away from the first guide groove, and is used to lock the male plug.

[0024] In a third aspect, the present application provides a connection mechanism, comprising the male plug and the female plug, wherein the male plug is plug-connected with the female plug.

[0025] In some possible implementations, the connecting mechanism includes:

[0026] In a first connection state, the first terminal and the second terminal are staggered in the circumferential direction of the connection mechanism; and

[0027] In a second connection state, the first terminals are connected to the second terminals in a one-to-one correspondence;

[0028] When the male plug rotates relative to the female plug, the connection mechanism switches from the first connection state to the second connection state, or the connection mechanism switches from the second connection state to the first connection state.

[0029] The beneficial effects of the present application are as follows: The present application proposes a male plug, a female plug, and a connecting mechanism, wherein the connecting mechanism includes a male plug and a female plug, and the male plug and the female plug are plugged together. The male plug includes a first base and a first terminal provided on the first base, and the first terminal is provided on at least a first circumferential side wall of the first base. The female plug includes a second base and a second terminal provided on the second base, wherein the female plug is provided with an insertion groove for plugging and connecting with the male plug, and the second terminal is provided on at least a second circumferential side wall of the insertion groove. When the male plug and the female plug are connected, the first base can be plugged into the insertion groove of the female plug, and the first terminal is electrically connected to the second terminal.

[0030] As the number of first and second terminals increases, the length of the male and female plugs can be increased along their respective axes to correspondingly increase the area of ​​the first and second sidewalls to accommodate the larger number of first and second terminals. This eliminates the need to increase the cross-sectional area of ​​the male and female plugs (i.e., the cross-section perpendicular to the axis). Consequently, the area occupied by the connection mechanism does not need to increase with the number of first and second terminals. Therefore, as the number of first and second terminals increases, the male and female plugs, as well as the connection mechanism provided by this application, can significantly reduce their occupied area compared to the prior art, avoiding interference with the arrangement of surrounding electrical components.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0059] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense.

[0061] Example 1

[0062] In the embodiment, a connection mechanism 100 is provided, which can be used for electrical connection between two devices to achieve transmission of power and data. For example, the connection mechanism 100 can be used for connection between a server host and a machine tool.

[0063] like Figure 1 and Figure 2 As shown, the connection mechanism 100 includes a male plug 10 and a female plug 20. The male plug 10 can be connected to the female plug 20, which can include both mechanical and electrical connections. Accordingly, on the one hand, it can achieve power and data transmission between the male plug 10 and the female plug 20; on the other hand, it can also achieve a mechanically fixed connection between the male plug 10 and the female plug 20, ensuring a stable electrical connection between the male plug 10 and the female plug 20. During use, the male plug 10 can be connected to one device via a wire or other structure, and the female plug 20 can also be connected to another device via a wire. When the male plug 10 and the female plug 20 are connected, the connection between the two devices is established.

[0064] In some embodiments, the male plug 10 and the female plug 20 can be mechanically connected by plugging together. When the male plug 10 and the female plug 20 are plugged together, a plugging direction 30 may be included.

[0065] like Figures 2 to 4As shown, in some embodiments, the male plug 10 may include a first base 11 and a plurality of first terminals 12. A first sidewall 1111 is provided circumferentially around the first base 11. It will be appreciated that the first sidewall 1111 surrounds a first axis 11a of the first base 11, and the first axis 11a is parallel to the insertion direction 30.

[0066] A plurality of first terminals 12 are at least disposed on the first side wall 1111 of the first base 11. When the male plug 10 is connected to the female plug 20, the first terminals 12 can be used to electrically connect to the female plug 20 to achieve transmission of power and data.

[0067] In an embodiment, the first base 11 can be used to carry the first terminal 12 . A user can hold the first base 11 to connect or disconnect the male plug 10 from the female plug 20 , thereby electrically connecting or disconnecting the first terminal 12 from the female plug 20 .

[0068] In some embodiments, the female plug 20 may include a second base 21 and a plurality of second terminals 22. The second base 21 is provided with an insertion slot 212 for engaging with the male plug 10. The second base 21 may be generally cylindrical with one end open. The insertion slot 212 includes a second sidewall 211 disposed around a second axis 21a of the second base 21. It will be appreciated that the second axis 21a is parallel to the insertion direction 30.

[0069] A plurality of second terminals 22 are provided on at least the second side wall 211 . The second terminals 22 can be used to electrically connect to the male plug 10 to achieve power and data transmission. In some embodiments, the second terminals 22 can be provided in a one-to-one correspondence with the first terminals 12 .

[0070] In some embodiments, when the male plug 10 is connected to the female plug 20, the male plug 10 can be inserted into the insertion slot 212 of the female plug 20, with the first side wall 1111 on the male plug 10 facing the second side wall 211 on the female plug 20. The second terminals 22 can be connected to the first terminals 12 in a one-to-one correspondence.

[0071] It is understandable that the cross-section of the plug is usually the main consideration for the plug space occupation, that is, the cross-section perpendicular to the plug direction 30. If the cross-section of the plug is too large, it will affect the arrangement of other electrical components around it, reducing the space utilization.

[0072] With the increasing integration and intelligence of devices, plugs used to connect devices are often equipped with a large number of pins to enable the transmission of power and multiple data paths. However, conventional methods typically increase the cross-sectional area of ​​the plug to accommodate this large number of pins, which undoubtedly increases the plug's footprint and affects the placement of other surrounding electrical components.

[0073] In this application, the first terminals 12 are disposed at least on the first circumferential sidewall 1111 of the male plug 10, and the second terminals 22 are disposed at least on the second circumferential sidewall 211 of the female plug 20, thereby positioning the terminals on the circumferential sidewalls of the plug. Therefore, when a larger number of terminals are required, the length of the male plug 10 and the female plug 20 can be extended along the mating direction 30 to increase the area of ​​the first sidewall 1111 and the second sidewall 211 to accommodate the larger number of terminals. Accordingly, the cross-sectional area of ​​the plug does not need to increase indefinitely with the increase in the number of terminals, thereby avoiding interference with the placement of other surrounding electrical components, avoiding space waste, and improving space utilization.

[0074] Example 2

[0075] A connection mechanism is provided in the embodiment. It can be understood that this embodiment can be a further improvement based on the first embodiment.

[0076] Combine Figures 2 to 4 As shown, in some embodiments, the first base 11 may include a connected insertion portion 111 and a handle portion 112, and the handle portion 112 may be fixedly connected to one end of the insertion portion 111. For example, the handle portion 112 may be fixedly connected to the insertion portion 111 by an integral arrangement, threaded connection, clamping, welding, bonding, riveting, etc. In some embodiments, the insertion portion 111 and the handle portion 112 may both be cylindrical and coaxially arranged.

[0077] In the embodiment, the plug portion 111 can be used to connect to the plug slot 212 of the female plug 20 to achieve the connection between the male plug 10 and the female plug 20. During use, the user can hold the handle 112 to insert or detach the plug portion 111 into or from the female plug 20.

[0078] Combined together Figure 6 and Figure 10 As shown, when the male plug 10 and the female plug 20 are plugged together, the plug portion 111 can be inserted from the open end of the plug slot 212. The inner diameter of the plug slot 212 can be slightly larger than the outer diameter of the plug portion 111 to facilitate smooth insertion of the plug portion 111 into the plug slot 212. When the male plug 10 and the female plug 20 are connected, the first axis 11a of the male plug 10 can be coaxial with the second axis 21a of the female plug 20, and both can be arranged along the axis of the connection mechanism 100.

[0079] In some embodiments, the radius of the handle portion 112 can be greater than the radius of the insertion portion 111, thereby forming an abutment wall 113 at the connection between the handle portion 112 and the insertion portion 111. The abutment wall 113 can be used to limit the insertion depth of the insertion portion 111 and the female plug 20, preventing over-insertion and damage to the first terminal 12 and / or the second terminal 22. In some embodiments, the outer diameter of the handle portion 112 can be greater than the inner diameter of the insertion slot 212. When the male plug 10 and the female plug 20 are fully inserted along the insertion direction 30, the end surface of the second base 21 near the opening of the insertion slot 212 can be limited and abutted against the abutment wall 113.

[0080] In some embodiments, the first sidewall 1111 may be a circumferential sidewall of the plug-in portion 111, and the first terminal 12 may be disposed on the first sidewall 1111. Accordingly, the first terminal 12 may be disposed on the plug-in portion 111. In some embodiments, the circumferential sidewall of the plug-in portion 111 may be provided with one, two, three, ten, twenty, thirty-five, forty, forty-eight, fifty, or other number of terminals, and the number of terminals may be determined as needed and is not specifically limited herein.

[0081] In an embodiment, when multiple first terminals 12 are provided, the first terminals 12 may be arranged in multiple rows and columns on the first sidewall 1111. The first terminals 12 in the same row may be evenly spaced and distributed around the first axis 11a. The first terminals 12 in the same column may be evenly spaced and distributed parallel to the first axis 11a. For example, the first terminals 12 on the plug-in portion 111 may be arranged in four rows of twelve columns, four rows of twenty columns, five rows of ten columns, etc.

[0082] like Figures 3 to 5 As shown, in some embodiments, the first terminal 12 may be a spring terminal.

[0083] Specifically, the first terminal 12 may include a conductive cap 121 and an elastic member 122. The conductive cap 121 may be protruded on the first side wall 1111 in a direction away from the first axis 11a, and the conductive cap 121 may be retracted relative to the plug-in portion 111 along the radial direction of the plug-in portion 111. It can be understood that the end of the conductive cap 121 close to the first axis 11a may be limited to the inside of the plug-in portion 111, and the end of the conductive cap 121 away from the first axis 11a may protrude from the first side wall 1111. Accordingly, a mounting groove 1112 for mounting the first terminal 12 may be provided at a corresponding position of the plug-in portion 111, and the end of the conductive cap 121 close to the first axis 11a may be limited to the corresponding mounting groove 1112, thereby preventing the conductive cap 121 from being separated from the plug-in portion 111.

[0084] The elastic member 122 can be assembled in the mounting groove 1112. One end of the elastic member 122 can abut against a side of the conductive cap 121 close to the first axis 11a, and the other end of the elastic member 122 can abut against a side wall of the mounting groove 1112 opposite the conductive cap 121. The elastic member 122 can be compressed between the side wall and the conductive cap 121. Accordingly, the elastic member 122 can be used to push the conductive cap 121 away from the first axis 11a, ensuring the stability of the connection between the first terminal 12 and the second terminal 22 when they are connected. In some embodiments, the elastic member 122 can be an elastic structure such as a spring, a spring, a flexible block, etc.

[0085] Of course, in other embodiments, when the conductive cap 121 is not subjected to external force, the elastic member 122 may also be in a natural state and abut against the conductive cap 121 and a side wall of the mounting groove 1112 opposite to the conductive cap 121 .

[0086] In some embodiments, the conductive cap 121 may be substantially hemispherical, so that the conductive cap 121 can be smoothly moved toward the direction of the mounting groove 1112 under the action of compression. Accordingly, during the connection process between the male plug 10 and the female plug 20, the problem of bending of the first terminal 12 can also be effectively avoided.

[0087] In some embodiments, the end of the conductive cap 121 facing away from the elastic member 122 can be used to electrically connect to the second terminal 22. The end of the conductive cap 121 facing away from the elastic member 122 can also be provided with a cut surface 1211 to increase the contact area between the conductive cap 121 and the second terminal 22 to improve the electrical connection stability.

[0088] In other embodiments, the first terminal 12 may be directly formed of a spring having a convex bump, and the first terminal 12 may be directly attached to the first side wall 1111, with the convex bump facing away from the first side wall 1111. Of course, the side of the first terminal 12 facing away from the convex bump may also be fixedly embedded in the insertion portion 111, with the convex bump protruding from the first side wall 1111 in a direction away from the first axis 11a.

[0089] It is understandable that a first circuit board (not shown) may be provided inside the male plug 10 , and the conductive cap 121 may be electrically connected to the first circuit board. For example, the conductive cap 121 may be electrically connected to the first circuit board via a wire.

[0090] Combine Figure 8 and Figure 9As shown, in some embodiments, the second terminals 22 may be provided on the second side wall 211 of the second base, and the second terminals 22 may be provided in a one-to-one correspondence with the first terminals 12, that is, the number of the second terminals 22 may be equal to the number of the first terminals 12. When a plurality of second terminals 22 are provided, the second terminals 22 may be distributed in multiple rows and columns on the second side wall 211. The plurality of second terminals 22 in the same row may be evenly spaced around the second axis 21a, and the spacing may be equal to the spacing between two adjacent first terminals 12 in the same row. The plurality of second terminals 22 in the same column may be evenly spaced parallel to the second axis 21a, and the spacing may be equal to the spacing between two adjacent first terminals 12 in the same column.

[0091] In some embodiments, the second terminal 22 can be a conductive sheet structure protruding from the second side wall 211. The side of the second terminal 22 facing away from the second side wall 211 can protrude a certain height relative to the second side wall 211. When the first terminal 12 and the second terminal 22 are connected to each other, the side of the second terminal 22 facing away from the second side wall 211 can mate with the cut surface 1211 of the corresponding conductive cap 121 to achieve electrical connection. It is understood that the female plug 20 can also include a second circuit board (not shown). The second circuit board is disposed within the second base 21, and the second terminal 22 can be electrically connected to the second circuit board via wires.

[0092] Combine Figure 5 and Figure 14 As shown, in some embodiments, when the first terminal 12 is not subjected to external pressure, the minimum distance between the cut surface 1211 and the first axis 11a is recorded as distance L1. When the first terminal 12 and the second terminal 22 are connected to each other, the maximum distance between the side surface of the second terminal 22 facing away from the second side wall 211 and the first axis 11a is recorded as distance L2. In this embodiment, distance L1 can be greater than or equal to distance L2. Therefore, when the first terminal 12 and the second terminal 22 are connected, the elastic member 122 can be squeezed, and the force of the elastic member 122 can cause the first terminal 12 to be tightly pressed against the second terminal 22, thereby ensuring a stable connection between the first terminal 12 and the second terminal 22.

[0093] like Figures 2 to 4 ,as well as Figures 6 to 8 As shown, further, in some embodiments, the male plug 10 further includes a first foolproofing component 13, and the female plug 20 is provided with a second foolproofing component 23 that cooperates with the first foolproofing component 13. The first foolproofing component 13 cooperates with the second foolproofing component 23 to achieve a foolproof connection between the male plug 10 and the female plug 20, avoid mismatching between the first terminal 12 and the second terminal 22, and ensure smooth transmission of power and data.

[0094] In this embodiment, the first foolproofing assembly 13 may include a plurality of first guide members 131, which may be arranged in a rotationally asymmetrical pattern around the first axis 11a. Accordingly, the second foolproofing assembly 23 may also include a corresponding number of second guide members 231, which may be arranged in a rotationally asymmetrical pattern around the second axis 21a, with each second guide member 231 corresponding to each first guide member 131.

[0095] It can be understood that a first guide member 131 and a corresponding second guide member 231 can be recorded as a set of guide components, and multiple sets of guide components are distributed in a non-rotationally symmetrical manner around the central axis of the connecting mechanism 100, so that multiple sets of guide components can form a corresponding fool-proof structure, that is, a first guide member 131 can only be connected to a corresponding second guide member 231, so that the user can conveniently connect the male plug 10 and the female plug 20 to ensure the one-to-one connection of the first terminal 12 and the second terminal 22, avoiding the problem of incorrect insertion.

[0096] For example, in some embodiments, three groups of guide assemblies may be provided, and the three groups of guide assemblies may be arranged in an isosceles triangle shape around the central axis of the connection mechanism 100, rather than an equilateral triangle shape. Accordingly, three groups of first guide members 131 may be provided, and may be arranged in corresponding isosceles triangle shapes around the first axis 11a. Three groups of second guide members 231 may also be provided, and may be arranged in corresponding isosceles triangle shapes around the second axis 21a, with each second guide member 231 corresponding to each first guide member 131.

[0097] In other embodiments, the guide assemblies may be arranged in two, four, or other groups, with a corresponding number of guide assemblies being non-rotationally symmetrically distributed around the central axis of the connection mechanism 100. Of course, in other embodiments, the guide assemblies may be arranged in one group, i.e., the male plug 10 is provided with a first guide member 131, and the female plug 20 is provided with a corresponding second guide member 231.

[0098] In the embodiment, when the male plug 10 is plugged into the female plug 20, the first guide member 131 can be connected in cooperation with the second guide member 231 at the corresponding position, which can guide the plugging connection between the male plug 10 and the female plug 20, thereby allowing the male plug 10 and the female plug 20 to be plugged into and connected smoothly.

[0099] In some specific embodiments, the first guide member 131 may be a guide block structure. The first guide member 131 may be protruded from the first sidewall 1111 and may protrude in a radial direction away from the first axis 11 a along the insertion portion 111 .

[0100] In some embodiments, the first guide member 131 can be arranged at one end of the plug-in portion 111 away from the hand-held portion 112, and is located on the side of the multiple rows of first terminals 12 away from the hand-held portion 112, so that when the male plug 10 contacts the female plug 20, the first guide member 131 can guide the connection with the female plug 20.

[0101] In some embodiments, a first guide member 131 may correspond to a row of first terminals 12 , that is, a first guide member 131 may be on the same straight line as a row of first terminals 12 at corresponding positions and parallel to the first axis 11 a .

[0102] like Figure 6 and Figure 7 As shown, correspondingly, the second guide member 231 can be a guide groove structure opened on the inner wall of the second base 21, that is, opened on the second side wall 211. The size of the guide groove structure can match the size of the first guide member 131, so that the first guide member 131 can slide smoothly along the second guide member 231.

[0103] In some embodiments, the second guide member 231 may include a first guide groove 2311 and a second guide groove 2312. The first guide groove 2311 may be arranged parallel to the second axis 21a, and an end of the first guide groove 2311 close to the opening of the insertion groove 212 may also be provided with an opening structure to facilitate smooth insertion of the first guide groove 2311 into the second guide groove 2312.

[0104] One end of the second guide groove 2312 can be connected to the end of the first guide groove 2311 away from the opening structure. The second guide groove 2312 is arranged around the second axis 21a, that is, the second guide groove 2312 can be a part of the annular groove. Accordingly, the second guide member 231 can be L-shaped.

[0105] In some embodiments, the first guide slot 2311 can be positioned corresponding to the gap between two adjacent rows of second terminals 22, and extend from an end near the opening of the insertion slot 212 to an end of the corresponding row of second terminals 22 away from the opening of the insertion slot 212. The end of the second guide slot 2312 away from the first guide slot 2311 can extend to a position corresponding to a row of second terminals 22 adjacent to the first guide slot 2311. That is, the end of the second guide slot 2312 away from the first guide slot 2311 can be aligned with the adjacent row of second terminals 22.

[0106] In other embodiments, the first guide member 131 may be a guide groove structure provided on the first side wall 1111. Accordingly, the first section of the guide groove of the first guide member 131 may be located between two adjacent first terminals 12. Accordingly, the second guide member 231 may be a guide block structure protruding from the second side wall 211 and aligned with a row of second terminals 22.

[0107] Correspondingly, such as Figures 10 to 15 As shown, the connection mechanism 100 may include two connection states, namely a first connection state 1001 and a second connection state 1002. When the male plug 10 is connected to the female plug 20, the first connection state 1001 and the second connection state 1002 may be included.

[0108] When the male plug 10 and the female plug 20 are in the first connection state 1001, the first guide member 131 is engaged with the first guide slot 2311. Accordingly, a row of first terminals 12 is located in the gap between two adjacent rows of second terminals 22. That is, the first terminals 12 and the second terminals 22 are offset in the circumferential direction of the connection mechanism 100. It is understood that the first connection state 1001 can be the connection state of the male plug 10 and the female plug 20 when the first guide member 131 slides along the first guide slot 2311 until it aligns with the second guide slot 2312. Simultaneously, the first terminals 12 and the second terminals 22 correspond to each other in rows, with a row of first terminals 12 and a corresponding row of second terminals 22 located on the same circle. The first terminals 12 and the second terminals 22 in the same row are staggered, and the first terminals 12 and the second terminals 22 in the same row do not contact each other. It is understood that during the insertion of the male plug 10 into the female plug 20 along the insertion direction 30, the first terminals 12 and the second terminals 22 remain in a non-contact state.

[0109] In this embodiment, when the first terminal 12 is not subjected to external pressure, the maximum distance between the cut surface 1211 and the first axis 11a can be slightly less than the distance between the second sidewall 211 and the first axis 11a. As the first guide member 131 slides along the first guide slot 2311, a gap can remain between the first terminal 12 and the second sidewall 211, thereby reducing insertion resistance during this stage and facilitating easier insertion of the male plug 10 into the female plug 20.

[0110] Of course, in other embodiments, when the first terminal 12 is not squeezed by external force, the maximum distance between the cut surface 1211 and the first axis 11 a may be equal to or slightly greater than the distance between the second side wall 211 and the first axis 11 a .

[0111] When the male plug 10 and the female plug 20 are in the second connection state 1002, the first guide member 131 can be located in the second guide slot 2312, and the first terminals 12 can be in contact and connected with the corresponding second terminals 22. After the male plug 10 is inserted into place along the first guide slot 2311 on the female plug 20, the male plug 10 can be rotated relative to the female plug 20 to cause the first guide member 131 to slide along the second guide slot 2312 until the first guide member 131 rotates to be aligned with an adjacent row of second terminals 22. Accordingly, the row of first terminals 12 corresponding to the first guide member 131 also rotates to correspond and connect with the row of second terminals 22. Accordingly, the first terminals 12 on the male plug 10 are connected one-to-one with the second terminals 22 on the female plug 20.

[0112] It is understood that the second guide slots 2312 in each of the three sets of second guide members 231 can extend counterclockwise from the corresponding first guide slots 2311. Accordingly, when the male plug 10 is rotated relative to the female plug 20, the three sets of first guide members 131 can simultaneously slide along the corresponding second guide slots 2312. Of course, in other embodiments, the three sets of second guide slots 2312 can extend clockwise from the corresponding first guide slots 2311.

[0113] When connecting existing plugs, the male and female pins typically have a long insertion stroke from contact to full connection. This results in high insertion resistance and difficulty, and can also lead to poor contact and short circuits during the insertion process, potentially damaging the device.

[0114] In the connection mechanism 100 provided herein, the first terminal 12 and the corresponding second terminal 22 have a relatively short connection stroke from contact to connection, thus preventing poor contact and short circuits. Furthermore, when the male plug 10 and the female plug 20 are plugged together, there is minimal plugging resistance, making the connection between the male plug 10 and the female plug 20 easier.

[0115] like Figure 7 、 Figure 11 、 Figure 14 and Figure 15As shown, in some embodiments, the female plug 20 further includes a locking member 24 for locking the male plug 10. Specifically, the locking member 24 can be disposed at the end of the second guide groove 2312 away from the first guide groove 2311, with the locking member 24 protruding from the bottom of the first guide groove 2311. The locking member 24 and the limiting wall 23121 at the end of the second guide groove 2312 away from the first guide groove 2311 form a limiting space for limiting the first guide member 131 and preventing it from sliding freely within the second guide groove 2312. When the first terminal 12 rotates to connect with the second terminal 22, the first guide member 131 can pass over the locking member 24 and be trapped between the locking member 24 and the limiting wall 23121. This locks the male plug 10 and the female plug 20, ensuring a stable connection between the male plug 10 and the female plug 20.

[0116] In one embodiment, the locking member 24 may be elastic, allowing the first guide member 131 to pass smoothly over the locking member 24. In some embodiments, the locking member 24 may have substantially the same structure as the first terminal 12. Specifically, the locking member 24 may include a telescopic cap and a spring. The telescopic cap is telescopically mounted at the bottom of the second guide slot 2312. The spring is compressed between the telescopic cap and the interior of the bottom of the second guide slot 2312, and the spring is configured to push the telescopic cap toward the second axis 21a. It will be appreciated that when the male plug 10 is rotated relative to the female plug 20, the first guide member 131 may gradually compress the locking member 24, causing it to retract into the interior of the bottom of the second guide slot 2312, allowing the first guide member 131 to pass smoothly. When the first guide member 131 rotates until it abuts the retaining wall 23121, the locking member 24 may be released. Accordingly, the locking member abuts the side of the first guide member 131 away from the retaining wall 23121, thereby retaining the first guide member 131.

[0117] In other embodiments, the spring in the locking member 24 may also be replaced by an elastic structure such as a spring sheet or a flexible block.

[0118] Of course, in other embodiments, the locking member 24 may directly adopt a structure such as a flexible protrusion.

[0119] During use, when the male plug 10 and the female plug 20 need to be connected, the first anti-mock component 13 on the male plug 10 is aligned with the second anti-mock component 23 on the second female plug 20, so that the male plug 10 is inserted into the female plug 20 from the open side of the insertion slot 212. First, the first guide member 131 can slide along the corresponding first guide slot 2311 until it aligns with the second guide slot 2312. Accordingly, the male plug 10 and the female plug 20 can be fully inserted in the insertion direction 30. During this process, the first terminal 12 and the second terminal 22 are offset. Subsequently, the male plug 10 can be rotated relative to the female plug 20, so that the first guide member 131 slides along the second guide slot 2312 until it is restrained between the locking member 24 and the retaining wall 23121, thereby locking the male plug 10 and the female plug 20. At this point, the first terminal 12 can be connected one-to-one with the second terminal 22.

[0120] When it is necessary to detach the male plug 10 from the female plug 20, the male plug 10 can be rotated in the opposite direction relative to the female plug 20 to unlock the first guide member 131 until the first guide member 131 rotates along the second guide groove 2312 until it aligns with the first guide groove 2311. This means that the connection mechanism 100 switches from the second connection state 1002 to the first connection state 1001. The male plug 10 can then be pulled out away from the female plug 20.

[0121] In summary, the male plug 10, female plug 20, and connection mechanism 100 provided in this application may have at least the following advantages:

[0122] (1) Save occupied area and improve space utilization;

[0123] (2) When the male plug 10 and the female plug 20 are connected, problems such as poor contact and short circuit can be avoided to ensure safe use;

[0124] (3) facilitate connection and disconnection, reduce operational resistance, and improve disassembly and assembly efficiency;

[0125] (4) It can avoid bending and other problems of the first terminal 12 and the second terminal 22, thereby extending the service life.

[0126] Example 3

[0127] The embodiment provides a connection mechanism, which may differ from the second embodiment in that:

[0128] like Figures 16 to 18 As shown, in the embodiment, the inserting portion 111 of the male plug 10 further includes a first end surface 1113 facing away from the gripping portion 112 , and the first terminals 12 are provided on both the first end surface 1113 and the first side wall 1111 .

[0129] In the embodiment, the first terminals 12 on the first end surface 1113 may be distributed in a ring shape in one or more layers, and the first terminals 12 on the same ring may be evenly spaced.

[0130] Correspondingly, the insertion slot 212 of the female plug 20 further includes a second end surface 213 located at the bottom of the slot. In the embodiment, the second end surface 213 and the second side wall 211 are both provided with second terminals 22.

[0131] The second terminals 22 on the second end surface 213 may also be arranged in one or more layers of circular rings, with the two terminals 22 on the same ring spaced evenly apart. In this embodiment, the one or more layers of circular rings on the second end surface 213 on which the second terminals 22 are located correspond one-to-one with the one or more layers of circular rings on the first end surface 1113 on which the first terminals 12 are located. The diameters of the two corresponding circular rings on which the second terminals 22 and the first terminals 12 are located are equal. In this embodiment, the second terminals 22 on the second end surface 213 are arranged in a one-to-one correspondence with the first terminals 12 on the first end surface 1113.

[0132] When the male plug 10 and the female plug 20 are in the first connection state 1001, on a plane perpendicular to the insertion direction 30, the projection of the first terminal 12 located on a circular ring on the first end surface 1113 and the projection of the second terminal 22 located on a corresponding circular ring on the second end surface 213 are located on the same circular ring, and the first terminal 12 and the second terminal 22 are sequentially staggered on the same circular ring. In this embodiment, the distance between the first terminal 12 and the adjacent second terminal 22 on the same circular ring can correspond to the sliding travel of the first guide member 131 along the second guide groove 2312. That is, when the first guide member 131 rotates to lock between the locking member 24 and the limiting wall 23121, the first terminal 12 can also rotate to fit and connect with the adjacent second terminal 22.

[0133] Example 4

[0134] The embodiment provides a connection mechanism, which may differ from the second embodiment in that:

[0135] like Figure 19 As shown, in the embodiment, the first terminals 12 may be distributed in a spiral array on the first sidewall 1111. Specifically, the first terminals 12 in the same row may extend along a spiral line, and the first terminals 12 in the same row may constitute a part of a convoluted structure in the spiral line.

[0136] Correspondingly, the second terminals 22 on the second side wall 211 of the female plug 20 may also be arranged in a corresponding spiral array. The second terminals 22 in the same row may extend along a spiral line, and the second terminals 22 in the same row may also form part of a spiral structure in the spiral line.

[0137] Accordingly, in the embodiment, the first guide groove 2311 in the second guide member 231 may also be a spiral groove consistent with the second terminals 22, that is, the first guide groove 2311 extends along the second axis 21a while also having a certain inclination along the circumference of the second side wall 211. The first guide groove 2311 is still located in the gap between two adjacent rows of second terminals 22.

[0138] Of course, in other embodiments, the second guide groove 2312 may also extend along a spiral line. Specifically, the second guide groove 2312 may extend along the circumference of the second sidewall 211 while being inclined parallel to the second axis 21a. As the first guide member 131 slides along the second guide groove 2312, the first terminal 12 may also slide along the corresponding spiral line until it is in contact with the corresponding second terminal 22. During this process, the male plug 10 and the female plug 20 can further engage.
