Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more particularly to an audio connector and its audio socket. Background Technology

[0002] Audio connectors include audio plugs and audio sockets. For example, in the use of equipment such as speakers, amplifiers, and mixing consoles, audio signals are transmitted between devices via audio plugs and audio sockets. Both audio plugs and audio sockets come in various types, and different types of audio connectors require corresponding types of sockets to achieve a connection.

[0003] In related technologies, a device typically has one or more different types of audio jacks and their functional switches. While installing only one audio jack reduces the size and weight of the device, enabling miniaturization, it requires adapters to connect different types of audio plugs, necessitating the preparation of various adapters and causing significant inconvenience for users. Conversely, installing multiple audio jacks allows for connection to various types of audio plugs, but it increases the size and weight of the device, hindering miniaturization.

[0031] To provide a clearer understanding of the technical features, objectives, and effects of this invention, specific embodiments are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the orientations or positional relationships indicated by terms such as "front," "rear," "upper," "lower," "left," "right," "longitudinal," "horizontal," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail" are based on the orientations or positional relationships shown in the accompanying drawings, and are constructed and operated in a specific orientation. They are only for the convenience of describing this technical solution and do not indicate that the device or element referred to must have a specific orientation; therefore, they should not be construed as limitations on this invention.

[0032] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. When an component is referred to as being "on" or "below" another component, the component can be located "directly" or "indirectly" on the other component, or there may be one or more intermediary components. The terms "first," "second," "third," etc., are only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0033] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0034] Figures 1 to 4 An audio connector 100 according to one embodiment of the present invention is shown, such as Figure 1 As shown, the audio connector 100 includes an audio plug 20 and an audio socket 10. The audio socket 10 is provided with conductive contacts that make conductive contact with at least two types of audio plugs 20, and an adjustment component for adjusting the state of the conductive contacts. The conductive contacts include a moving contact 71, and the moving contact 71 can switch between a first state and a second state under the action of the adjustment component.

[0035] Therefore, during use, depending on the type of audio plug 20 to be inserted, the adjusting component adjusts the moving contact 71 corresponding to that audio plug 20 to the first state, thereby achieving connection between the current type of audio plug 20 and the audio socket 10. This audio socket 10 is suitable for connecting at least two types of audio plugs 20, enabling device miniaturization and providing convenience for users.

[0036] like Figures 2 to 4As shown, the audio jack 10 includes a housing 1, conductive contacts for conductive contact with at least two types of audio plugs 20, and an adjustment assembly for adjusting the state of the conductive contacts. It is understood that in the prior art, the audio plugs 20 include various types, such as... Figure 6 As shown, the audio plug 20 includes a three-pole audio plug 20, which includes a three-pole 3.5mm audio plug 20a, a three-pole 4.4mm audio plug 20b, and a three-pole 6.35mm audio plug 20c. Different types of audio plugs 20 with the same number of poles have different parameters such as diameter and length. Of course, the audio plug 20 also includes two-pole audio plugs 20, four-pole audio plugs 20, and other types of audio plugs with different numbers of poles.

[0037] The audio plug 20 has contact poles corresponding to its number of poles. For example, a three-pole audio plug 20 has three contact poles, which are, from the root to the tip, a ground contact pole 201, a cold contact pole 202, and a hot contact pole 203. This is prior art and will not be described in detail here. Understandably, the audio plug 20 can be connected to an audio socket 10 with the same number of poles. Therefore, the audio socket 10 can be a two-pole, three-pole, or four-pole audio socket 10, and the number of poles of the audio socket 10 can be set according to requirements.

[0038] Conductive contacts are located on the inner side of the housing 1, providing conductive contact for at least two types of audio plugs 20. Understandably, the arrangement of the conductive contacts in the audio jack 10 is related to the number of poles of the audio jack 10; that is, the position and number of conductive contacts correspond to the position and number of each contact pole of the corresponding audio plug 20, ensuring that when different types of audio plugs 20 are inserted, there are corresponding conductive contacts corresponding to each contact pole of the audio plug 20 to achieve conductive contact.

[0039] The conductive contacts include at least one moving contact 71, and each moving contact 71 corresponds to at least one type of audio plug 20. Understandably, a moving contact 71 may correspond to only one contact pole of one type of audio plug 20, or it may correspond to only one contact pole of two or more types of audio plugs 20. Understandably, a moving contact 71 cannot simultaneously correspond to two different contact poles of the same type of audio plug 20, otherwise a short circuit will occur.

[0040] The movable contact 71 is movable relative to the housing 1. The movable contact 71 includes a first state of conductive contact with the corresponding type of audio plug 20 and a second state of disconnection from the corresponding type of audio plug 20. The adjusting component drives the movable contact 71 to move relative to the housing 1 to control the movable contact 71 to switch between the first state and the second state.

[0041] The regulating component is used to adjust the state of the conductive contacts, specifically, in conjunction with... Figures 2 to 4 As shown, the adjustment component includes a main body 2 and a movable part 3; the outer shell 1 has a hollow structure, the main body 2 is located inside the outer shell 1, and the inner side of the main body 2 is provided with a channel 213 for inserting an audio plug 20.

[0042] The movable contact 71 is disposed on the main body 2; the main body 2 may be generally cylindrical or cylindrical in shape, for example, cylindrical or cylindrical in cross-section of other shapes. The side wall 21 of the main body 2 is provided with a receiving groove 211 communicating with the channel 213, and the movable contact 71 is movably disposed in the receiving groove 211; the movable part 3 is movably disposed on the main body 2, and during the movement of the movable part 3, it drives the movable contact 71 to extend out of the receiving groove 211 to reach the first state, or keeps the movable contact 71 in the receiving groove 211 to reach the second state.

[0043] In this embodiment, the movable part 3 may include a sleeve part 31 axially movable and fitted onto the periphery of the main body part 2, and a protrusion 32 protruding into the main body part 2 from the inner side of the sleeve part 31. The protrusion 32 is correspondingly provided with the movable contact 71, and the protrusion 32 is located on the side of the movable contact 71 away from the channel 213. The protrusion 32 includes a contact end face 321 that contacts and engages with the movable contact 71. Thus, when the movable part 3 slides up and down along the main body part 2 via the sleeve part 31, the protrusion 32, through its contact end face 321, drives the movable contact 71 to extend out of the receiving groove 211, or keeps the movable contact 71 in the receiving groove 211. The movable contact 71 can be moved by rotation.

[0044] In other embodiments, the movable part 3 can also move the movable contact 71 by moving radially along the main body 2. The movable part 3 may include an actuated end and an end connected to the movable contact 71, so that when the movable part 3 moves radially along the main body 2 towards the channel 213, it causes the movable contact 71 to extend in a translational manner; when the movable part 3 moves radially away from the channel 213 along the main body 2, it causes the movable contact 71 to retract into the receiving groove 211 in a translational manner. In some specific embodiments, the movable contact 71 may be an electric contact, and the extension and retraction of the electric contact can be controlled by a computer.

[0045] In embodiments where the movable contact 71 moves by rotation, the movable contact 71 can be set individually or in groups. Understandably, in embodiments where the movable contact 71 is set individually, one end of the movable contact 71 can be located on the main body 2, near the channel 213, to facilitate its extension. The connection method can be detachable or fixed. The protrusion 32 and the movable contact 71 are engaged by a beveled surface. Specifically, the movable contact 71 engages with the contact end face 321 of the protrusion 32 through its side facing away from the channel 213. Both the side of the movable contact 71 facing away from the channel 213 and the contact end face 321 of the protrusion 32 are planar, and these two planes are inclined, with the same inclination or arranged in other compatible forms. The two planes can automatically contact the contact 71, which is located on the main body 2. One end of the contact 71 is tilted upward or downward toward the side away from the channel 213, so that the contact 71 can be rotated to extend or retract during the up and down sliding of the protrusion 32.

[0046] In this embodiment, the protrusions 32 are correspondingly provided with the moving contacts 71. That is, the number and position of the protrusions 32 can be set according to the number and position of the moving contacts 71. The moving contacts 71 can be implemented using butterfly-shaped copper sheets or other conductive metals. Of course, in embodiments where the moving contacts 71 are provided alone, the movable part 3 can also adopt the above-mentioned structure in which the movable part 3 drives the moving contacts 71 to move by moving radially along the main body 2.

[0047] In this embodiment, the moving contacts 71 are implemented in a group, and the principle of their arrangement is similar to that in the embodiment where the moving contacts 71 are arranged individually. Specifically, in conjunction with Figure 3 and Figure 4 As shown, four moving contacts 71 can be configured, with two moving contacts 71 arranged axially in pairs, and the two axially arranged moving contacts 71 connected as one unit to form two moving contact groups. It can be understood that two moving contacts 71 in the same moving contact group can correspond to the same contact pole of different types of audio plugs 20 respectively, and the two moving contacts 71 in the same moving contact group are led out through the same lead wire 74, which facilitates wiring.

[0048] Two moving contacts 71 in the same moving contact group are connected, and the connection point of the two moving contacts 71 is provided on the main body 2. The connection point is located on the main body 2 near the channel 213 so that either moving contact 71 can extend out. The connection method can be detachable or fixed.

[0049] Each moving contact 71 engages with the contact end face 321 of the protrusion 32 through its side facing away from the channel 213. Understandably, the number and position of the protrusions 32 correspond to the number and position of the moving contact group; that is, in an embodiment where there are two moving contact groups, there are two protrusions 32.

[0050] The protrusion 32 and the moving contact 71 are engaged by a bevel. Specifically, the moving contact 71 engages with the contact end face 321 of the protrusion 32 through its side facing away from the channel 213. Both the side of the moving contact 71 facing away from the channel 213 and the contact end face 321 of the protrusion 32 are planar. Furthermore, the two moving contacts 71 in the same moving contact group are arranged at an angle, for example, at an obtuse angle, to facilitate extension.

[0051] Each protrusion 32 has two contact end faces 321, and the two contact end faces 321 respectively cooperate with two moving contacts 71 in the same moving contact group. The two contact end faces 321 of each protrusion 32 are inclined, and the two contact end faces 321 can be automatically inclined from one end to the other on the main body 2 away from the channel 213. It can be understood that the contact end face 321 closer to the insertion end 2131 of the channel 213 is inclined upward and the other contact end face 321 is inclined downward. The protrusion 32 is obtuse angle protrusion and is adapted to the moving contact 71 group.

[0052] The two moving contacts 71 in the moving contact group can be arranged radially symmetrically, and correspondingly, the two contact end faces 321 of the protrusion 32 can be arranged radially symmetrically. The structures of the two moving contact groups can be the same or similar, and the axial distance between the two moving contacts 71 in the same moving contact group and the axial distance between the two moving contact groups 71 can be adjusted according to the requirements.

[0053] The moving contact 71 can be implemented using a butterfly-shaped copper sheet or other conductive metal. The receiving grooves 211 are correspondingly provided with the moving contacts 71, meaning the number and position of the receiving grooves 211 correspond to the number and position of the moving contacts 71 in the moving contact group. In this embodiment, two receiving grooves 211 can be provided corresponding to the same moving contact group, and the two receiving grooves 211 are axially spaced by partition walls 25. The connection between the two moving contacts 71 can be located on the partition walls 25.

[0054] Two moving contacts 71 in the same moving contact group correspond to the same functional contact poles of different types of audio plugs 20, and the moving contacts 71 in the two moving contact groups correspond to different contact poles. In this embodiment, the four moving contacts 71 in the two moving contact groups are axially offset sequentially, that is, the two moving contact groups are axially offset, and in the moving contact group away from the socket end 2131 of the channel 213, the moving contact 71 near the socket end 2131 is located between two moving contacts 71 in the other moving contact group, and the four moving contacts 71 are not on the same radial direction. This makes the two moving contacts 71 near the socket end 2131 in the two moving contact groups correspond to the same type of audio plug 20, and the two moving contacts 71 away from the socket end 2131 correspond to another audio plug 20 of the same type.

[0055] Understandably, when the two contact end faces 321 of the protrusion 32 respectively contact and engage with the two moving contacts 71 in the same moving contact group, and both moving contacts 71 in the same moving contact group remain in the receiving groove 211, for ease of description, this state is defined as a balanced state, i.e. Figure 4 The state shown.

[0056] In a balanced state, when the protrusions 32 move towards the socket end 2131, the two protrusions 32 will correspondingly drive the moving contacts 71 in the two moving contact groups that are closer to the socket end 2131 to rotate towards the channel 213 side. Since the two moving contacts 71 in the same moving contact group are connected as one unit, the other two moving contacts 71 will also rotate towards the side away from the channel 213. In a balanced state, when the protrusions 32 move towards the direction away from the socket end 2131, the two protrusions 32 will correspondingly drive the moving contacts 71 in the two moving contact groups that are farther from the socket end 2131 to rotate towards the channel 213 side, and the other two moving contacts 71 will also rotate towards the side away from the channel 213.

[0057] In other words, for the audio plug 20 corresponding to the moving contact 71 of the plug end 2131 near the channel 213 in the two moving contact groups, the first state includes two moving contacts 71 near the plug end 2131 extending out of the receiving groove 211, and the other two moving contacts 71 retracting into the receiving groove 211, thereby achieving conductive contact of the audio plug 20; the second state includes two moving contacts 71 away from the plug end 2131 extending out of the receiving groove 211, and the other two moving contacts 71 retracting into the receiving groove 211, thereby achieving disconnection of the audio plug 20; of course, the balanced state also belongs to the second state for the audio plug 20.

[0058] Understandably, the structure of the aforementioned moving contact group can be configured in a three-pole or four-pole audio jack 10. For example, when the aforementioned moving contact group is configured in a three-pole audio jack 10, the two moving contacts 71 in each moving contact group can respectively correspond to the cold end contact pole 202 and the hot end contact pole 203 of the three-pole audio plug 20. Of course, in other embodiments, the structure of the aforementioned moving contact group can also be configured in a two-pole audio jack 10. The two-pole audio plug 20 includes a ground end contact pole and a signal contact pole. Since the ground end contact poles of different types of audio plugs 20 are relatively close in position, the axial distance between the two moving contacts 71 in the two moving contact groups corresponding to the same contact pole can be set to be small; the axial distance between each moving contact 71 can be adjusted according to specific requirements.

[0059] Understandably, the axial distance between two moving contacts 71 in the same moving contact group, the axial distance between two moving contact groups, and the number and position of moving contact groups and individual moving contacts 71 can all be set and adjusted according to requirements, as long as an audio jack 10 can be used to connect at least two types of audio plugs 20.

[0060] In other embodiments, the moving contacts 71 are arranged in groups, that is, in one of the two moving contact groups mentioned above. Specifically, there may be two moving contacts 71, which are axially arranged and connected as a single unit to form a moving contact group; the movable part 3 has a protrusion 32, and the protrusion 32 has two contact end faces 321 corresponding to the two moving contacts 71 respectively. It can be understood that, for example, in the embodiment of the two-pole audio jack 10, since the two-pole audio plug 20 includes a ground contact pole and a signal contact pole, the two moving contacts 71 in the moving contact group can correspond to the signal contact poles of two different types of two-pole audio plugs 20 respectively.

[0061] In other words, the moving contacts 71 in each pole audio socket 10 can be set individually and / or implemented in the form of moving contact groups. The number and position of individually set moving contacts 71 and moving contact groups are set according to the requirements.

[0062] The side wall 21 of the main body 2 is provided with a guide rail 212 for the movable part 3 to move along the axial direction of the main body 2. The guide rail 212 extends along the axial direction of the main body 2 and corresponds to and communicates with the receiving groove 211. The sleeve part 31 of the movable part 3 is sleeved on the outer periphery of the main body 2, and the protrusion 32 passes through the guide rail 212 and cooperates with the moving contact 71. The sleeve part 31 is cylindrical and adapted to the main body 2. It can be understood that the receiving groove 211 is located near the inner side of the side wall 21 of the main body 2, and the guide rail 212 is located near the outer side of the side wall 21 of the main body 2.

[0063] Combination Figures 3 to 5 As shown, in this embodiment, the conductive contact may further include two first stationary contacts 72. Figure 3 (Only one is shown), the two first stationary contacts 72 are axially offset and disposed on the inner side of the main body 2, and the two first stationary contacts 72 are farther away from the socket end 2131 than the moving contact 71.

[0064] Understandably, the two first stationary contacts 72 are provided to correspond to the longest audio plug 20 among various types of audio plugs 20, and can correspond to the cold end contact 202 and the hot end contact 203 of the audio plug 20, respectively. For example, in a three-pole audio socket 10 that is compatible with a 3.5mm audio plug 20a, a 4.4mm audio plug 20b, and a 6.35mm audio plug 20c, since the 6.35mm audio plug 20c is the longest, the two first stationary contacts 72 can correspond to the cold end contact 202 and the hot end contact 203 of the 6.35mm audio plug 20c, respectively. Furthermore, since the diameter and length parameters of the 3.5mm audio plug 20a and the 4.4mm audio plug 20b are smaller than the corresponding parameters of the 6.35mm audio plug 20c, the two first stationary contacts 72 will not make conductive contact with the 3.5mm audio plug 20a and the 4.4mm audio plug 20b.

[0065] The adjusting component adjusts the state of the moving contact group by moving the movable part 3. For example... Figures 2 to 4 As shown, the adjustment assembly may also include an adjustment part 4 and an elastic part 5. The main body 2 has a first connecting section 22 at the insertion end 2131 of the channel 213. The adjustment part 4 includes a connecting part 41 and a limiting part 42. The connecting part 41 is connected to the outer periphery of the first connecting section 22 by a threaded structure.

[0066] The limiting part 42 is provided at one end of the connecting part 41 near the main body part 2, and the limiting part 42 corresponds to and abuts against the sleeve part 31; the elastic part 5 is provided at one end of the movable part 3 away from the adjusting part 4, and the elastic part 5 constantly pushes the movable part 3; during the up and down movement of the connecting part 41 through the threaded structure, the limiting part 42 and the outer shell 1 form an active space 13 for the movable part 3 to move up and down.

[0067] One end of the guide rail 212 extends to a position near the insertion end 2131, thereby forming a baffle 23 corresponding to the guide rail 212 at the insertion end 2131 of the main body 2, which can prevent the movable part 3 from dislodging from the main body 2. The protrusion 32 can be provided near the axial end of the sleeve part 31, and the specific configuration can be determined according to requirements.

[0068] The outer casing 1 can be arranged in a cylindrical shape to fit the main body 2, and the inner wall surface of the outer casing 1 is clearance-fitted with the movable part 3, so that the movable part 3 can move axially. The outer casing 1 has a first boss 11 protruding towards the main body 2 on the inner side wall near the end away from the insertion end 2131. The first boss 11 at least partially blocks the movable part 3 in the radial direction. For example, the first boss 11 partially blocks the sleeve part 31 in the radial direction to restrict the movement of the movable part 3 towards the end away from the insertion end 2131. The first boss 11 cooperates with the limiting part 42 to form an axially movable space 13 for the movable part 3 to move axially up and down. The position of the first boss 11 can be set according to the axial dimension of the sleeve part 31. The first boss 11 is located at the end of the movable part 3 away from the insertion end 2131.

[0069] In this embodiment, when the connecting part 41 is fully screwed to the first connecting segment 22, the axial distance between the limiting part 42 and the end face of the first boss 11 is equal to or close to the axial dimension of the sleeve part 31; when the connecting part 41 is partially connected to the first connecting segment 22, the distance between the limiting part 42 and the end face of the first boss 11 is greater than the axial dimension of the sleeve part 31, thereby forming an active space 13 that is greater than the axial dimension of the sleeve part 31, so that the active part 3 can move axially.

[0070] The elastic part 5 can be implemented using a spring. The elastic part 5 is located at the end of the movable part 3 away from the adjusting part 4. The elastic part 5 is sleeved on the periphery of the main body part 2 and is located between the main body part 2 and the first boss 11. Furthermore, the elastic part 5 corresponds to the sleeve part 31. In this embodiment, the end face of the first boss 11 corresponds radially to a portion of the sleeve part 31, so that the elastic part 5 can correspond to the sleeve part 31.

[0071] The outer casing 1 has a second protrusion 12 on its inner sidewall near the end away from the insertion end 2131, protruding towards the main body 2. This second protrusion 12 is closer to the end away from the insertion end 2131 than the first protrusion 11, for mounting the elastic part 5. The two ends of the elastic part 5 abut against the end of the sleeve part 31 and the end face of the second protrusion 12, respectively, so that the elastic part 5 constantly pushes the movable part 3. Understandably, the axial dimension of the elastic part 5 can be set according to the axial dimension of the movable space 13.

[0072] The main body 2 is connected to the inner side of the outer shell 1. In this embodiment, the end of the main body 2 away from the insertion end 2131 is provided with a second connecting section 24. The second connecting section 41 and the inner surface of the second boss 12 can be connected by a threaded structure.

[0073] The adjustment assembly also includes an elastic clamping part 6 for adjusting the size of the plug end 2131 of the channel 213. The adjustment part 4 further includes a mating part 43 disposed at the end of the connecting part 41 away from the limiting part 42; the elastic clamping part 6 is disposed inside the mating part 43 and the first connecting section 22; the mating part 43 and the inner side of the first connecting section 22 are provided with mating surfaces for the elastic clamping part 6 to move up and down and for limiting the elastic clamping part 6; the inner side of the elastic clamping part 6 is provided with a cylindrical through hole 61 for the audio plug 20 to be inserted, and the elastic clamping part 6 changes the size of the cylindrical through hole 61 during its up and down movement.

[0074] Understandably, the first connecting section 22 and the mating part 43 are hollow to allow the audio plug 20 to be inserted. The elastic clamping part 6 is located inside the mating part 43 and the first connecting section 22. Specifically, in conjunction with... Figures 2 to 4 As shown, the elastic clamping part 6 is arranged in a ring shape, and the inner wall surface of the elastic clamping part 6 is cylindrical to form a cylindrical through hole 61, thereby adapting to the shape of the audio plug 20.

[0075] The elastic clamping part 6 has a plurality of deformation gaps 62 in its circumferential direction, and the plurality of deformation gaps 62 are evenly distributed at intervals. Each deformation gap 62 extends axially from one end of the elastic clamping part 6 to the other end near the elastic clamping part 6. The deformation gaps 62 are arranged in opposite directions and penetrate through the inner and outer sides of the elastic clamping part 6. Thus, the elastic clamping part 6 can expand or shrink through the deformation gaps 62. Since the deformation gaps 62 are arranged in opposite directions, the deformation gaps 62 at both ends can act simultaneously, so that the columnar through hole 61 maintains its columnar shape during the deformation of the elastic clamping part 6.

[0076] The mating surfaces include a first mating surface 221 and a second mating surface 431 respectively disposed on the inner surfaces of the first connecting section 22 and the mating part 43; the outer surface of the elastic clamping part 6 includes a first inclined surface 63 near the end of the main body part 2 and a second inclined surface 64 away from the end of the main body part 2, and the first mating surface 221 and the second mating surface 431 respectively correspond to and mate with the first inclined surface 63 and the second inclined surface 64.

[0077] In this embodiment, each pair of mating surfaces are mated by inclined surfaces; specifically, the first mating surface 221 can be gradually expanded outward from one end near the main body 2 toward the other end toward the connecting part 41; the second mating surface 431 is located at one end of the mating part 43 near the connecting part 41, and the second mating surface 431 is gradually narrowed inward from one end near the connecting part 41 toward the end away from the connecting part 41. The arrangement of the two mating surfaces can limit the elastic clamping part 6 and prevent the elastic clamping part 6 from coming out.

[0078] Correspondingly, the first inclined surface 63 and the second inclined surface 64 of the elastic clamping part 6 are respectively provided to gradually narrow inward from the junction of the two inclined surfaces to both ends of the elastic clamping part 6. The first inclined surface 63, the second inclined surface 64, the first mating surface 221, and the second mating surface 431 are all conical surfaces, and the inclination of the two mating surfaces is the same. Of course, in other embodiments, the two mating surfaces may also be provided in other compatible forms.

[0079] In this embodiment, the two mating surfaces are pressed tightly against the elastic clamping part 6, meaning the elastic clamping part 6 is always in a pressed state. Understandably, when the adjusting part 4 is turned to move the connecting part 41 up and down, the position of the second mating surface 431 will also move up and down. Therefore, when the space enclosed by the two mating surfaces shrinks, the elastic clamping part 6 elastically contracts under the pressure of the two mating surfaces, causing the columnar through hole 61 to shrink; when the space enclosed by the two mating surfaces expands, the elastic clamping part 6 expands due to its own tension to engage with the two mating surfaces, causing the columnar through hole 61 to expand.

[0080] Understandably, the elastic clamping part 6 can be made of metal, for example, it can be implemented using a spring collet as in the prior art; of course, the elastic clamping part 6 can also be made of silicone or other materials that can achieve this elastic deformation. The deformation range of the elastic clamping part 6 can be set according to the size of the audio plug 20 to be used.

[0081] In this embodiment, Figure 4 In the equilibrium state shown, the elastic clamping part 6 is at its maximum deformable size, allowing the largest size audio plug 20 to be inserted; therefore, when the connecting part 41 moves up or down, the elastic clamping part 6 deforms in the form of a reduced columnar through hole 61 due to the engagement of the two mating surfaces.

[0082] When the movable part 3 moves upward, the corresponding moving contact 71 makes conductive contact with the smallest audio plug 20, and when the movable part 3 moves downward, the corresponding moving contact 71 makes conductive contact with the larger audio plug 20. Therefore, the elastic clamping part 6 shrinks more when the movable part 3 moves upward than when the movable part 3 moves downward.

[0083] The degree of reduction of the elastic clamping part 6 is related to the length and inclination of the mating surfaces. The inclination and length of the first mating surface 221 and the second mating surface 431 can be the same or different. Understandably, when the lengths of the first mating surface 221 and the second mating surface 431 are the same, the inclination of the first mating surface 221 can be less than the inclination of the second mating surface 431. Therefore, when the movable part 3 moves the same distance axially, the degree of reduction of the elastic clamping part 6 when moving upwards is greater than the degree of reduction when moving downwards. Understandably, in embodiments where the two contact end surfaces 321 of the protrusion 32 and the two moving contacts 71 of the same moving contact group are radially symmetrically arranged, this can be achieved by having the inclination of the first mating surface 221 less than the inclination of the second mating surface 431.

[0084] Of course, in embodiments where the inclination of the first mating surface 221 and the second mating surface 431 is the same, the slope length of the second mating surface 431 can be greater than the slope length of the first mating surface 221, thereby allowing the elastic clamping part 6 to shrink more by moving more axial distance upward.

[0085] The inner surface of the mating part 43 also includes an open surface 432 at the end farther away from the main body 2 than the second mating surface 431. The open surface 432 gradually slopes outward from the second mating surface 431 toward the end farther away from the main body 2 and is tapered. Understandably, the open surface 432 facilitates the insertion of the audio plug 20. Understandably, the mating part 43 can be screwed to adjust the position of the adjusting part 4. The cross-section of the mating part 43 may be hexagonal, allowing for manual operation or screwing using a tool such as an external hexagon.

[0086] The conductive contact also includes a second stationary contact 73, which is disposed on the inner side of the first connecting section 22. Understandably, when the audio plug 20 is inserted, the inner side of the first connecting section 22 corresponds to the root of the audio plug 20, i.e., the grounding contact. Therefore, the second stationary contact 73 is disposed on the inner side of the first connecting section 22 so that it can correspond to the grounding contact of various types of audio plugs 20. Of course, the second stationary contact 73 can also be disposed on the inner side of the main body 2, as long as it can correspond to the grounding contact of various types of audio plugs 20.

[0087] At least some of the conductive contacts are offset in the circumferential direction of the housing 1. In this embodiment, at least some of the conductive contacts corresponding to the same type of audio plug 20 are offset in the circumferential direction, wherein two moving contact groups may be disposed opposite to each other on both sides of the main body 2.

[0088] The first stationary contact 72 and the second stationary contact 73 are both pressure-contact type contacts, which can be implemented using elastic copper sheets. Understandably, the elastic clamping part 6 plays a role in fixing and balancing the audio plug 20 to a certain extent; the staggered arrangement of the conductive contacts can further fix and strengthen the balance of the audio plug 20 in the circumferential direction, making the audio plug 20 less likely to come out.

[0089] like Figure 5 As shown, for ease of wiring, the moving contact group and the first stationary contact 72, corresponding to the same type of contact electrode, are connected and led out through the same lead wire 74 to form a whole. The lead wire 74 is embedded inside the main body 2 and extends from the end of the main body 2 away from the socket end 2131 for easy wiring. The connection point of the two moving contacts 71 in the moving contact group is connected to the lead wire 74 through a connector 75, allowing the moving contact group to rotate.

[0090] Furthermore, the audio jack 10 may also include a locking mechanism for indicating that the adjustment is in place, such that a ticking sound is emitted when the connector 41 is turned to a position corresponding to a type of audio plug 20.

[0091] Furthermore, a fixing panel 14 is provided on the periphery of the outer casing 1. The fixing panel 14 is located at one end near the plug end 2131. The fixing panel 14 is provided with screw holes 141. There may be four screw holes 141, which are evenly distributed on the fixing panel 14 in a circumferential manner, so as to fix the audio socket 10 to the device panel. The device may be a speaker, power amplifier, mixing console, etc.

[0092] Combination Figures 1 to 7 As shown, the following example, using a three-pole audio jack 10, illustrates the configuration of the conductive contacts. This three-pole audio jack 10 is suitable for connecting three-pole 3.5mm audio plugs 20a, 4.4mm audio plugs 20b, and 6.35mm audio plugs 20c. Each audio plug 20 includes a grounding contact 201, a cold contact 202, and a hot contact 203.

[0093] The conductive contacts of the three-pole audio jack 10 include two moving contact groups, two first stationary contacts 72, and one second stationary contact 73. The second stationary contact 73 is located on the inner side of the first connecting section 22 and can make conductive contact with the grounding terminal contact 201 of the three types of three-pole audio plugs 20 mentioned above.

[0094] Two moving contact groups are arranged in the above-described moving contact group structure, and the two moving contact groups have the same structure. The two moving contact groups are axially offset, and the four moving contacts 71 in the two moving contact groups are sequentially axially offset. In the two moving contact groups, the two moving contacts 71 near the socket end 2131 of the channel 213 correspond to the cold end contact 202 and the hot end contact 203 of the three-pole 3.5mm audio plug 20a, respectively, and the two moving contacts 71 away from the socket end 2131 correspond to the cold end contact 202 and the hot end contact 203 of the three-pole 4.4mm audio plug 20b, respectively. Of the two first stationary contacts 72, the first stationary contact 72 near the socket end 2131 corresponds to the cold end contact 202 of the three-pole 6.35mm audio plug 20c, and the other first stationary contact 72 corresponds to the hot end contact 203 of the three-pole 6.35mm audio plug 20c.

[0095] For ease of description and differentiation, the conductive contacts are defined as follows: In the two moving contact groups, the two moving contacts 71 corresponding to the cold end contact 202 and hot end contact 203 of the three-pole 3.5mm audio plug 20a are defined as the first right moving contact 711 and the first left moving contact 712, respectively; the two moving contacts 71 corresponding to the cold end contact 202 and hot end contact 203 of the three-pole 4.4mm audio plug 20b are defined as the second right moving contact 713 and the second left stationary contact 714, respectively. In the two first stationary contacts 72, the two first stationary contacts 72 corresponding to the cold end contact 202 and hot end contact 203 of the three-pole 6.35mm audio plug 20c are defined as the first right stationary contact 721 and the first left stationary contact 722, respectively.

[0096] The first right moving contact 711, the second right moving contact 713, and the first right stationary contact 721 are connected to the same lead wire 74. The first left moving contact 712, the second left stationary contact 714, and the first left stationary contact 722 are connected to another lead wire 74. The second stationary contact 73 is connected to yet another lead wire 74. The three leads 74 extend from the end of the main body 2 away from the socket end 2131. The first right moving contact 711, the second right moving contact 713, the first left moving contact 712, and the second left stationary contact 714 are all connected to the leads 74 via connectors 75.

[0097] When in use, when the active part 3 is located Figure 7 When the position shown is the equilibrium state, the cylindrical through hole 61 of the elastic clamping part 6 is at its largest size, and a three-pole 6.35mm audio plug 20c can be inserted. At this time, all moving contacts 71 are located in the receiving groove 211, and the second stationary contact 73, the first right stationary contact 721, and the first left stationary contact 722 can respectively make conductive contact with the grounding terminal contact 201, the cold terminal contact 202, and the hot terminal contact 203 of the three-pole 6.35mm audio plug 20c.

[0098] When the 3.5mm audio plug 20a with three poles needs to be inserted, the mating part 43 is turned so that the adjusting part 4 moves upward, thereby moving the elastic clamping part 6 upward, until the columnar through hole 61 of the elastic clamping part 6 shrinks to the position for inserting the 3.5mm audio plug 20a with three poles. At this time, the first right moving contact 711 and the first left moving contact 712 extend out from the receiving groove 211, and the second right moving contact 713 and the second left stationary contact 714 retract into the receiving groove 211. The second stationary contact 73, the first right moving contact 711, and the first left moving contact 712 can respectively make conductive contact with the grounding terminal contact 201, the cold terminal contact 202, and the hot terminal contact 203 of the 3.5mm audio plug 20a with three poles.

[0099] When the 4.4mm audio plug 20b with three poles needs to be inserted, the mating part 43 is turned so that the adjusting part 4 moves downward, thereby moving the elastic clamping part 6 downward, until the columnar through hole 61 of the elastic clamping part 6 shrinks to the position for inserting the 4.4mm audio plug 20a with three poles. At this time, the second right moving contact 713 and the second left stationary contact 714 extend out from the receiving groove 211, and the first right moving contact 711 and the first left moving contact 712 retract into the receiving groove 211. The second stationary contact 73, the second right moving contact 713, and the second left stationary contact 714 can respectively make conductive contact with the grounding terminal contact 201, the cold terminal contact 202, and the hot terminal contact 203 of the 4.4mm audio plug 20a with three poles.

[0100] Understandably, the three-pole audio jack 10 can also be used to connect the two-pole audio plug 20, and the wiring can be changed according to the contact poles required for conductive connection.

[0101] The audio connector 100 includes the aforementioned audio socket 10 and an audio plug 20 adapted to the audio socket 10. Understandably, the number of poles of the audio socket 10 in the audio connector 100 may be the same as the number of poles of the audio plug 20. For example, the audio connector 100 includes a three-pole audio socket 10 and a three-pole audio plug 20, wherein the three-pole audio plug 20 includes a three-pole 3.5mm audio plug, a three-pole 4.4mm audio plug, and a three-pole 6.35mm audio plug.

[0102] The audio plug 20 of the present invention has the characteristics of simple structure, strong versatility and easy use, which can realize the miniaturization of the device and bring convenience to the user.

[0103] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
