Description

Technical Field

[0001] This application relates to the field of audio plug technology, and in particular to a rotary control audio connector and connection method. Background Technology

[0002] In today's era of continuous advancement in electronic devices, audio connectivity technology has also made significant progress. As an indispensable component for audio signal transmission, audio connectors are widely used in various audio devices, such as speaker systems, headphones, and microphones. They play a crucial role in ensuring the stable and efficient transmission of audio signals, directly affecting the user experience and performance of audio devices. With the increasing diversification and complexity of audio technology, higher requirements are placed on the reliability and ease of operation of audio connectors. Good audio connectivity technology can effectively reduce signal interference, improve audio quality, bring users a better listening experience, and promote the development of the audio industry towards higher quality.

[0003] In traditional audio connection technologies, various methods are typically used to connect and secure male and female connectors. One common method is a snap-fit ​​connection, where the snaps on the male connector and the slots on the female connector engage to complete the connection. This method provides a certain degree of connection stability, but it lacks proper positioning during insertion, which may require considerable force, and the snaps are prone to damage after prolonged use. Another method is to use a threaded tightening structure, where the male and female connectors are tightened together using threads to enhance the connection's strength. However, this method is more cumbersome to operate, requiring a certain amount of time to tighten, and the threads may wear down after repeated use, leading to a decrease in connection effectiveness.

[0004] Regarding the aforementioned technologies, the inventors believe that the locking methods of elastic clips and slots in existing audio connectors lack axial auxiliary positioning or have insufficient insertion positioning effect, which makes it easy to cause misalignment and jamming when pulling out, resulting in low ease of operation. Summary of the Invention

[0005] To address the problems mentioned in the background art, this application provides a rotary controllable audio connector and a connection method.

[0006] In a first aspect, this application provides a rotary controllable audio connector, employing the following technical solution: A rotary controllable audio connector includes a male connector and a female connector for mating with the male connector. The male connector includes a male connector housing, an operating sleeve rotatably mounted on the insertion end of the male connector housing, and an elastic magnetic snap disposed on the insertion end of the operating sleeve. The female connector includes a female connector housing, an inner core, and an insulating sleeve sleeved outside the inner core. The inner core has a magnetic element that matches the elastic magnetic snap. The outer side of the insulating sleeve is provided with a limiting groove extending circumferentially along the insulating sleeve. The limiting groove is used for the elastic magnetic snap to engage. The end of the limiting groove is provided with a release groove extending axially along the insulating sleeve. When the elastic magnetic snap slides to the release groove, the elastic magnetic snap and the magnetic element are misaligned.

[0007] By adopting the above technical solution, a magnetic suction part and an elastic buckle are set on the operating sleeve of the male connector, and a limiting groove and a release groove are set on the insulating sleeve of the female connector. When the male connector is inserted into the female connector, the elastic buckle engages with the limiting groove to axially limit the male connector, while the magnetic suction part and the magnetic force component are aligned to achieve axial auxiliary positioning and fixation. When it is necessary to disconnect the connection, the operating sleeve is rotated to make the elastic buckle slide into the release groove, which restricts the path of the male connector being pulled out. At the same time, the magnetic suction part and the magnetic force component are misaligned to weaken the magnetic attraction force, thereby improving the stability and anti-interference ability of the audio connection, and enhancing the positioning effect and convenience during insertion and removal.

[0008] Preferably, the elastic magnetic buckle has a magnetic attraction part and an elastic buckle, and the outer side of the insulating sleeve is also provided with a guide groove along the axial direction. The guide groove is used to guide the elastic buckle to slide to the limiting groove when the male head is inserted.

[0009] By adopting the above technical solution, the insulating sleeve is further restricted. By setting a guide groove, when the male head is inserted, it slides along the guide groove to the limiting groove through the elastic buckle. This allows the elastic buckle to enter the limiting groove along a designated path, while reducing wear when the pin and inner core are inserted, and improving the smoothness and accuracy of the insertion.

[0010] Preferably, the insulating sleeve has a tapered portion at one end near the male end, the outer diameter of which gradually increases along the insertion direction of the male end, and the tapered portion is used to guide the elastic buckle to open and slide into the guide groove when the male end is inserted.

[0011] By adopting the above technical solution, the structure of the insulating sleeve is defined. By setting a tapered part at the end of the insulating sleeve, the elastic buckle is gradually opened and smoothly enters the guide groove when the male head is inserted, which reduces the resistance in the initial stage of insertion, improves the insertion and removal feel and positioning effect, and thus further improves the axial alignment of the male and female heads.

[0012] Preferably, the outer side of the operating sleeve is provided with a control handle, and the top of the control handle has multiple anti-slip stripes.

[0013] By adopting the above technical solution, the structure of the operating sleeve is defined. By setting a control handle with anti-slip stripes on the outside of the operating sleeve, it is convenient for the user to apply force to rotate the operating sleeve. At the same time, the anti-slip stripes can increase the friction between the fingers and the handle, thereby improving the reliability of the rotation operation.

[0014] Preferably, there are multiple magnetic suction parts and multiple magnetic force components, and the magnetic suction parts and magnetic force components are evenly arranged circumferentially along the end faces of the operating sleeve and the inner core, respectively.

[0015] By adopting the above technical solution, the magnetic attraction parts and magnetic components are defined, and multiple circumferentially distributed magnetic attraction parts and magnetic components are set to cooperate, so that the magnetic attraction force between the male and female heads is more uniformly distributed, thereby improving the coaxiality and connection stability after docking.

[0016] Preferably, the outer peripheral wall of the male head housing is provided with alignment scale lines, which are used to mark the overlapping and misaligned positions of the magnetic attraction part and the magnetic component.

[0017] By adopting the above technical solution, the male connector housing is further defined. By setting alignment scale lines on the outer peripheral wall of the male connector housing, users can intuitively judge whether the magnetic suction part and the magnetic force component are in the overlapping suction position or the misaligned release position by observing the position of the scale lines. This realizes the visual recognition of the locking and unlocking states, and improves the sense of confirmation and accuracy of operation.

[0018] Preferably, the male connector housing has a protrusion at the insertion end, and the inner core has an elastic retainer that mates with the protrusion. The protrusion is used to press the elastic retainer to form a snap-fit ​​when the male connector is inserted into the female connector.

[0019] By adopting the above technical solution, by setting a protrusion at the insertion end of the male connector housing, the protrusion squeezes the elastic clip on the inner core to form an additional axial clamping when the male connector is inserted into the female connector, which further improves the connection reliability after the male connector and the female connector are inserted.

[0020] Preferably, the outer side of the male housing plug end is provided with an annular mounting groove, and the inner wall of the operating sleeve is provided with an annular flange that mates with the annular mounting groove.

[0021] By adopting the above technical solution, the installation method of the operating sleeve is further defined. By setting an annular mounting groove on the outside of the male head housing and cooperating with the annular flange on the inner wall of the operating sleeve, the operating sleeve can be rotated relative to the male head housing. At the same time, the axial displacement of the operating sleeve is restricted, ensuring the stability and smoothness of the rotation operation.

[0022] Preferably, the inner wall of the plug end of the male connector housing is provided with a magnetic shielding wall, and the magnetic shielding wall is provided with a grounded shielding metal layer.

[0023] By adopting the above technical solution, the structure of the inner wall of the male connector housing is defined. By setting a magnetic shielding wall on the inner wall of the male connector housing and setting a grounded shielding metal layer inside the magnetic shielding wall, electromagnetic interference in the pin area is isolated, thereby improving the shielding effect of audio signal transmission.

[0024] Secondly, this application provides a method for connecting a rotary controllable audio connector, employing the following technical solution: A method for connecting a rotary control audio connector includes the following steps: S1: Insert the male connector into the female connector along the axial direction. The pin of the male connector housing is inserted into the inner core to complete the insertion and engagement. At the same time, the protrusion at the insertion end of the male connector housing presses against the elastic clip on the inner core to form a snap-fit. The elastic clip is opened by the tapered part and slides into the limiting groove along the guide groove. At this time, the magnetic part and the magnetic component are arranged opposite each other and attract each other. The male connector and the female connector are in a locked state, and the control handle is in the overlapping position. S2: Release the locking state of the male and female heads, rotate the operating sleeve through the control handle to make the elastic buckle slide along the limiting slide groove, rotate the control handle to the misaligned position, and at the same time drive the magnetic suction part to rotate relative to the magnetic force member, so that the magnetic suction part and the magnetic force member are switched from facing each other to misaligned arrangement; S3: At this time, the operating sleeve drives the elastic buckle to slide to the position of the release groove, pulls the male head out along the axis, the elastic buckle disengages along the release groove, and at the same time, the protrusion squeezes the elastic clip to deform and make room, and the pin exits from the inner core, completing the unlocking and separation of the male head and the female head.

[0025] By adopting the above technical solution, automatic locking and positioning can be completed simply by inserting the male head into the female head; when unlocking, simply rotate the operating sleeve to misalign the magnetic parts, and the male head can be easily pulled out. The locking and unlocking status can be intuitively perceived through changes in magnetic force and the position of the control handle, effectively avoiding misoperation and improving the safety and convenience of use.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Axial auxiliary positioning and fixation are achieved by the magnetic suction part and the magnetic force component being directly engaged. The elastic buckle is slid into the release groove by rotating the operating sleeve, which restricts the path of the male connector being pulled out. At the same time, the magnetic suction part and the magnetic force component are misaligned to weaken the magnetic attraction force, thereby improving the stability and anti-interference ability of the audio connection, while enhancing the positioning effect and convenience when plugging and unplugging. 2. By setting a guide groove, when the male connector is inserted, it slides along the guide groove to the limit groove through the elastic buckle, so that the elastic buckle can enter the limit groove along the specified path. At the same time, it reduces the wear of the pin and the inner core during the insertion and improves the smoothness and accuracy of the insertion. 3. By setting a tapered part at the end of the insulating sleeve, the guide effect of the tapered surface is used to gradually open the elastic buckle and smoothly enter the guide groove when the male is inserted, which reduces the resistance in the initial stage of insertion, improves the insertion and removal feel and positioning effect, and thus further improves the axial alignment of the male and female.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses a rotary controllable audio connector and its connection method, referring to... Figure 1 and Figure 2 A rotary controllable audio connector includes a male connector 1 and a female connector 2 for mating with the male connector 1. The male connector 1 has pins 15 for inserting into an inner core 22 to transmit audio signals.

[0031] Reference Figure 3The male connector 1 includes a male connector housing 11, an operating sleeve 12 rotatably mounted on the insertion end of the male connector housing 11, and an elastic magnetic buckle 3 disposed on the insertion end of the operating sleeve 12. The elastic magnetic buckle 3 has a magnetic attraction part 13 and an elastic snap 14. The male connector housing 11 is made of plastic and has the characteristics of good insulation and light weight. The operating sleeve 12 is rotatably mounted on the insertion end of the male connector housing 11 through the cooperation of an annular mounting groove 18 and an annular flange 122. An annular mounting groove is provided on the outer side of the insertion end of the male connector housing 11. 18. The inner wall of the operating sleeve 12 is provided with an annular flange 122 that mates with the annular mounting groove 18. The annular flange 122 mates with the annular mounting groove 18, allowing the operating sleeve 12 to rotate flexibly around the male head housing 11. The magnetic suction part 13 uses a low-cost ferrite magnet. The elastic buckle 14 is installed on the insertion end of the operating sleeve 12 and is made of spring steel. It has the advantages of good elasticity and not easy to deform. The elastic buckle 14 is used to mate with the limiting slide groove 233 of the female head 2 to achieve connection. Both the magnetic suction part 13 and the elastic buckle 14 are provided at the end of the operating sleeve 12 for inserting the female head 2. There are four magnetic suction parts 13, which are arranged at the end of the operating sleeve 12 and evenly distributed along the circumference of the operating sleeve 12. There is one elastic buckle 14, which is arranged between two of the magnetic suction parts 13. When the operating sleeve 12 is rotated, the magnetic suction part 13 and the elastic buckle 14 move accordingly. The magnetic suction part 13 attracts the magnetic force 221 on the female head 2, providing an initial attraction force and a certain axial positioning effect for the connection. The elastic buckle 14 restricts the axial displacement of the male head 1 by locking into the limiting groove 233, thereby further strengthening the stability of the connection. The two work together to improve the stability of the connection between the male head 1 and the female head 2.

[0032] Reference Figures 4 to 6The female connector 2 includes a female connector housing 21, an inner core 22, and an insulating sleeve 23 sleeved on the outside of the inner core 22. The inner core 22 has a magnetic element 221 that matches the magnetic attraction part 13. The outer side of the insulating sleeve 23 is provided with a limiting groove 233 extending circumferentially along the insulating sleeve 23. The limiting groove 233 is used for the elastic buckle 14 to be engaged. The end of the limiting groove 233 is provided with a release groove 234 extending axially along the insulating sleeve 23. When the elastic buckle 14 slides to the release groove 234, the magnetic attraction part 13 and the magnetic element 221 are misaligned. The female connector housing 21 is also made of plastic. The number of magnetic suction parts 13 is the same as that of four, and the positions of the two correspond one-to-one when the male head 1 is inserted. The four magnetic force members 221 are arranged at the end of the inner core 22 and are spaced apart along the circumference of the insulating sleeve 23, and a staggered interval is formed between every two magnetic force members 221. The insulating sleeve 23 is made of plastic material to avoid interference with the audio signal. The limiting slide groove 233 and the release slide groove 234 are processed on the outside of the insulating sleeve 23. The limiting slide groove 233 extends along the circumference of the insulating sleeve 23, and the release slide groove 234 is set along the axial direction of the insulating sleeve 23 and arranged at the end of the limiting slide groove 233. When the male connector 1 is inserted into the female connector 2, the magnetic suction part 13 and the magnetic force member 221 are positioned one-to-one, thus generating mutual attraction to position and assist the insertion of the male connector 1. The rotating operating sleeve 12 drives the elastic buckle 14 to slide in the limiting slide groove 233, thereby adjusting the position of the magnetic suction part 13 and the magnetic force member 221. When disassembly is required, the elastic buckle 14 is slid into the release slide groove 234. At this time, the magnetic suction part 13 and the magnetic force member 221 are misaligned, the magnetic force is weakened, and it is easy for the male connector 1 and the female connector 2 to separate.

[0033] Reference Figure 5 and Figure 6 The insulating sleeve 23 is also provided with a guide groove 232 along the axial direction on the outer side. The guide groove 232 is used to guide the elastic buckle 14 to slide into the limiting groove 233 when the male head 1 is inserted. The guide groove 232 is integrally formed with the insulating sleeve 23 by injection molding, providing a path in a specified direction for the sliding of the elastic buckle 14 when the male head 1 is inserted, which facilitates quick and accurate connection, and at the same time reduces the wear of the pin 15 and the inner core 22 during the insertion of the male head 1. The insulating sleeve 23 has a tapered part 231 at one end near the male head 1. The outer diameter of the tapered part 231 gradually increases along the insertion direction of the male head 1. The tapered part 231 is used to guide the elastic buckle 14 to open and slide into the guide groove 232 when the male head 1 is inserted. The design of the tapered part 231 makes the male head 1 more smoothly inserted. The elastic buckle 14 will be opened along the inclined surface of the tapered part 231 and then smoothly enter the guide groove 232.

[0034] Reference Figure 3The outer side of the operating sleeve 12 is provided with a control handle 121. The top of the control handle 121 has multiple anti-slip stripes 1211. The control handle 121 is made of plastic, which is convenient for users to hold and operate. The anti-slip stripes 1211 design can increase the friction and prevent the hand from slipping when rotating the operating sleeve 12. The outer peripheral wall of the male head housing 11 is provided with alignment scale lines. The alignment scale lines are used to mark the overlapping and misaligned positions of the magnetic suction part 13 and the magnetic force member 221. The alignment scale lines are laser-etched on the male head housing 11. Users can understand the relative position of the magnetic suction part 13 and the magnetic force member 221 through the alignment scale lines, which is convenient for operation.

[0035] The male connector housing 11 has a protrusion 16 at its insertion end, and the inner core 22 has an elastic clip 222 that cooperates with the protrusion 16. The elastic clip 222 is an elastic card located at the bottom of the inner core 22. The protrusion 16 is located on the inner wall of the insertion end and is used to squeeze the elastic card to form a snap-fit ​​when the male connector 1 and the female connector 2 are inserted and mated. The snap-fit ​​between the protrusion 16 and the elastic clip 222 further enhances the stability of the connection between the male connector 1 and the female connector 2. At the same time, the inner wall of the insertion end of the male connector housing 11 has a magnetic shielding wall 17, and the magnetic shielding wall 17 has a grounded shielding metal layer inside. The magnetic shielding wall 17 is made of magnetic material, and the shielding metal layer is copper foil. The grounded shielding metal layer can effectively reduce the interference of external magnetic fields on audio signals and improve the quality of audio signal transmission.

[0036] This application also includes a method for connecting a rotary controllable audio connector, comprising the following steps: S1: Insert the male head 1 into the female head 2 along the axial direction. The pin 15 of the male head housing 11 is inserted into the inner core 22 to complete the insertion. At the same time, the protrusion 16 at the insertion end of the male head housing 11 presses the elastic clip 222 on the inner core 22 to form a snap. The elastic buckle 14 is opened by the tapered part 231 and slides into the limiting groove 233 along the guide groove 232. At this time, the magnetic part 13 and the magnetic force member 221 are arranged opposite each other and attract each other. The male head 1 and the female head 2 are in the locked state, and the control handle 121 is in the overlapping position. S2: Release the locking state of male head 1 and female head 2. Rotate the operating sleeve 12 by controlling handle 121 to make the elastic buckle 14 slide along the limiting slide groove 233. Rotate control handle 121 to the misaligned position, and at the same time drive the magnetic suction part 13 to rotate relative to the magnetic force member 221, so that the magnetic suction part 13 and the magnetic force member 221 are switched from facing each other to misaligned arrangement. S3: At this time, the operating sleeve 12 drives the elastic buckle 14 to slide to the position of the release groove 234, pulls the male head 1 out along the axis, the elastic buckle 14 disengages along the release groove 234, and at the same time the protrusion 16 squeezes the elastic clip 222 to deform and make room, the pin 15 exits from the inner core 22, and the male head 1 and female head 2 are unlocked and separated.

[0037] The implementation principle of a rotary control audio connector according to an embodiment of this application is as follows: During the insertion and locking process, the user holds the male connector 1 and axially inserts the operating sleeve 12 into the opening of the female connector 2. During insertion, the protrusion 16 at the insertion end of the male connector housing 11 first contacts the elastic retainer 222 on the inner core 22. As the insertion continues, the protrusion 16 squeezes the elastic retainer 222, causing it to elastically deform outwards. After the protrusion 16 passes the elastic retainer 222, the elastic retainer 222 rebounds and forms an axial lock on the protrusion 16. At the same time, the elastic buckle 14 on the end face of the operating sleeve 12 contacts the end of the insulating sleeve 23. Under the guidance of the conical surface of the conical part 231, the elastic buckle 14 gradually opens and slides into the guide groove 232 along the axis. It continues to be pushed in until the elastic buckle 14 reaches the bottom of the guide groove 232 and enters the limiting groove 233. At this time, the pin 15 of the male head 1 is inserted into the inner core 22 of the female head 2 to realize the connection of the audio signal. The four magnetic parts 13 on the end face of the operating sleeve 12 are aligned with the four magnetic parts 221 on the end face of the inner core 22. They attract each other under the action of magnetic attraction. The male head 1 and the female head 2 are in a stable locked state. At this time, the control handle 121 is aligned with the overlapping position of the outer peripheral wall of the male head housing 11.

[0038] During the unlocking and separation process, when it is necessary to disconnect, the user drives the operating sleeve 12 to rotate a certain angle relative to the male head housing 11 around the axis by controlling the handle 121. During the rotation, the elastic buckle 14 slides circumferentially from the limiting slide groove 233. At the same time, the operating sleeve 12 drives the four magnetic suction parts 13 to rotate synchronously, so that the magnetic suction parts 13 and the magnetic force member 221 switch from the directly aligned overlapping state to the misaligned arrangement state. During the process, the magnetic attraction force gradually decreases. When the operating sleeve 12 rotates 45° relative to the male head housing 11, the control handle 121 is aligned with the misaligned position. At this time, the elastic buckle 14 just slides to the position of the release slide groove 234. The user pulls the male head 1 outward along the axis, and the elastic buckle 14 slides out along the release slide groove 234. At the same time, the protrusion 16 squeezes the elastic clip 222 again to deform and make room. The pin 15 exits from the socket, completing the separation of the male head 1 and the female head 2.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
