[0002] In current headphone products, the headphone plug and the headphone speaker are usually connected as an integrated structure through a headphone cable. Different types of headphone plugs and headphone speakers cannot be replaced as needed, resulting in inconvenience in use. Summary of the Invention

[0003] The purpose of the present application is to provide a replaceable headphone connector and a headphone structure. The replaceable headphone connector can detachably connect the wires of the headphone plug and the headphone speaker, making it easy to replace different headphone plugs and headphone speakers as needed.

[0004] The embodiment of the present application is implemented as follows:

[0005] In a first aspect, an embodiment of the present application provides a replaceable headphone connector, comprising: a first connecting seat and a second connecting seat.

[0006] The first connecting seat includes a first seat body, a first connecting component and a first needle body. A first conductive wire is provided through the first seat body. One end of the first conductive wire is connected to the first needle body. The other end of the first conductive wire is used to connect to the headphone plug. The first needle body is fixed to the first seat body. The first connecting component includes a first locking sleeve and a first connecting piece. The first locking sleeve ring is provided outside the first needle body, and the first connecting piece is provided on the first locking sleeve.

[0007] The second connecting seat includes a second seat body, a second connecting assembly and a second needle body for plugging and cooperating with the first needle body. A second conductive wire is arranged through the second seat body, one end of the second conductive wire is connected to the second needle body, and the other end of the second conductive wire is used to connect to the headphone speaker. The second needle body is fixed to the second seat body, and the second connecting assembly includes a second locking sleeve and a second connecting piece. The second locking sleeve ring is arranged outside the second needle body, and the second connecting piece is arranged on the second locking sleeve. The first locking sleeve is used to slidably cooperate with the second locking sleeve, and the second connecting piece is detachably connected to the first connecting piece.

[0008] In the above technical solution, the first conductive wire and the second conductive wire are used for signal transmission, one end of the first conductive wire is connected to the first needle body and the other end is used to connect to the headphone plug, one end of the second conductive wire is connected to the second needle body and the other end is used to connect to the headphone speaker, and the wires of the headphone plug and the headphone speaker can be connected by plugging and fitting the first needle body and the second needle body. The first locking sleeve ring is arranged outside the first needle body, and the second locking sleeve ring is arranged outside the second needle body, which can better protect the needle body. The second connector is detachably connected to the first connector, and the first connector and the second connector are slidably matched to enable the first connector and the second connector to be connected and disassembled. The above arrangement makes the first connecting seat and the second connecting seat detachably connected, which is convenient for replacing different headphone plugs and headphone speakers as needed.

[0009] In some optional embodiments, the first connector and the second connector can be snap-connected.

[0010] In the above technical solution, the first connecting member and the second connecting member are detachably connected by a snap-fit method, and the connection and disassembly operations are convenient.

[0011] In some optional embodiments, the first locking sleeve is used to be slidably mounted in the second locking sleeve, the first connecting member includes a limiting boss arranged on the outer wall of the first locking sleeve, and the second connecting member includes a limiting flange arranged on the inner wall of the second locking sleeve. When the first connecting member and the second connecting member are in a locked state, the side of the limiting flange away from the first connecting seat abuts against the side of the limiting boss away from the second connecting seat, and the first locking sleeve and the second locking sleeve can be rotatably matched to allow the first connecting member and the second connecting member to be in an open state and a locked state.

[0012] In the above technical solution, locking is achieved by abutting the side of the limiting flange away from the first connecting seat against the side of the limiting boss away from the second connecting seat. The first and second locking sleeves are rotatably engaged to change the open and locked states, resulting in a simple arrangement. In the locked state, the first and second locking sleeves can be effectively prevented from moving away from each other, thereby preventing them from becoming detached, and the connection is stable.

[0013] In some optional embodiments, the limiting flange is annularly arranged along the inner wall of the second locking sleeve, and the limiting flange is provided with a limiting opening for the limiting boss to pass axially through the limiting flange.

[0014] In the above technical solution, the limiting opening is provided to allow the limiting boss to pass through when the first locking ferrule and the second locking ferrule are mated, so that the limiting boss can move axially to the side of the limiting flange away from the first connecting seat, facilitating locking through further rotation. The limiting flange is annularly arranged along the inner wall of the second locking ferrule. The limiting flange has a large circumferential distribution range on the inner wall of the second locking ferrule. In the locked state, the limiting flange can better abut the limiting boss, ensuring a more stable connection.

[0015] In some optional embodiments, the second connecting member also includes an elastic member, the second locking sleeve can be slidably mounted outside the second seat body, and the elastic member is mounted between the end of the second locking sleeve away from the first connecting seat and the second seat body, and is used to drive the second locking sleeve to move in a direction away from the first connecting seat.

[0016] In the above technical solution, an elastic member is arranged between the second seat body and the second locking sleeve, and the elastic member is used to drive the second locking sleeve to move in the direction away from the first connecting seat, so that the second locking sleeve has a tendency to move in the direction away from the first connecting seat in the locked state, so that the limiting flange can better press against the limiting boss, and self-locking is achieved through the elastic member, thereby avoiding relative movement of the first connecting seat and the second connecting seat in the axial direction, and the locking state is more stable.

[0017] In some optional embodiments, the second locking sleeve includes a first connecting sleeve and a second connecting sleeve, the first connecting sleeve is threadedly connected to the second connecting sleeve, the limiting flange is arranged at the end of the first connecting sleeve away from the second connecting sleeve, and the elastic member is arranged between the second seat body and the end of the second locking sleeve away from the first connecting seat.

[0018] In the above technical solution, the first connecting sleeve and the second connecting sleeve are connected by a threaded connection to realize the rotatable connection between the first locking sleeve and the second locking sleeve. The threaded connection can prevent the first locking sleeve and the second locking sleeve from rotating arbitrarily, thereby effectively preventing the limiting boss and the limiting flange from separating from each other, and can ensure that the limiting flange can better press against the limiting boss in the locked state, and the locked state is more stable.

[0019] In some optional embodiments, the first needle body is a female needle and the second needle body is a male needle.

[0020] In the above technical solution, the male pin and the female pin are conveniently plugged in and matched.

[0021] In some optional embodiments, the second seat body is provided with a male needle protection sleeve, the male needle protection sleeve is arranged outside the second needle body, and the male needle protection sleeve is used to be slidably mounted between the first needle body and the first locking sleeve.

[0022] In the above technical solution, the male needle protection sleeve can better protect the second needle body. The male needle protection sleeve is used to be slidably mounted between the first needle body and the first locking sleeve. In the embodiment where the first locking sleeve is used to be slidably mounted within the second locking sleeve, the first locking sleeve is slidably mounted between the male needle protection sleeve and the first locking sleeve, and the structure has good stability.

[0023] In some optional embodiments, one of the inner wall of the first locking sleeve and the outer wall of the male needle protective sleeve is provided with a guide boss, and the other of the inner wall of the first locking sleeve and the outer wall of the male needle protective sleeve is provided with a guide groove, and the guide boss and the guide groove are slidably matched.

[0024] In the above technical solution, a guide boss and a guide groove are provided between the inner wall of the first locking ferrule and the outer wall of the male needle protection sleeve for sliding engagement. This allows the first and second connecting seats to move in a predetermined direction when approaching and moving away from each other, resulting in good alignment and easy operation when connected. Furthermore, the cooperation between the guide boss and the guide groove also acts as a limiter in the locked state, preventing radial movement between the first and second connecting seats and ensuring a more stable locked state.

[0025] In the second aspect, an embodiment of the present application provides an earphone structure, including an earphone plug, an earphone speaker, and the replaceable earphone connector provided in the embodiment of the first aspect, the earphone plug is connected to the end of the first conductive wire away from the first needle body, and the earphone speaker is connected to the end of the second conductive wire away from the second needle body.

[0026] In the above technical solution, the headphone plug and the headphone speaker are connected to the first connecting socket and the second connecting socket respectively.

[0042] Example

[0043] See also Figure 1-Figure 2 In a first aspect, an embodiment of the present application provides a replaceable headphone connector 100, comprising a first connection base 110 and a second connection base 120. The first connection base 110 is used to connect to a headphone plug, and the second connection base 120 is used to connect to a headphone speaker. The first connection base 110 and the second connection base 120 are detachably connected, making it easy to replace different headphone plugs and headphone speakers as needed.

[0044] See also Figure 3-Figure 4 The first connecting seat 110 includes a first seat body 111, a first connecting assembly and a first needle body 113. The first connecting assembly and the first needle body 113 are both arranged in the first connecting seat 110. A first conductive wire (not shown) is provided through the first seat body 111. One end of the first conductive wire is connected to the first needle body 113, and the other end of the first conductive wire is used to connect to the headphone plug, so that when the connecting seat is connected to the headphone plug, the first needle body 113 can be electrically connected to the headphone plug, thereby realizing signal transmission. The first connecting assembly includes a first locking sleeve 1121 and a first connector. The first locking sleeve 1121 is provided in the first connecting seat 110 and is arranged around the outside of the first needle body 113, which can effectively protect the first needle body 113. The first connector is provided in the first locking sleeve 1121.

[0045] See also Figure 5-Figure 6The second connecting seat 120 includes a second seat body 121, a second connecting assembly and a second needle body 123. The second connecting assembly and the second needle body 123 are both arranged on the first connecting seat 110. A second conductive wire (not shown) is provided through the second seat body 121. One end of the second conductive wire is connected to the second needle body 123, and the other end of the second conductive wire is used to connect to the headphone speaker, so that when the connecting seat is connected to the headphone speaker, the second needle body 123 can be electrically connected to the headphone speaker, thereby realizing signal transmission. The second connecting assembly includes a second locking sleeve 1221 and a second connecting piece. The second locking sleeve 1221 is provided on the second connecting seat 120 and is arranged around the outside of the second needle body 123, which can effectively protect the second needle body 123. The second connecting piece is provided on the second locking sleeve 1221.

[0046] In an embodiment of the present application, the first locking sleeve 1121 is used to slidably cooperate with the second locking sleeve 1221. The first locking sleeve 1121 and the second locking sleeve 1221 can move relative to each other along the axis so that the first connecting seat 110 and the second connecting seat 120 can move closer to and farther away from each other. The second needle body 123 is used to plug and cooperate with the first needle body 113. When the first connecting seat 110 and the second connecting seat 120 are close to each other, the first needle body 113 can be plugged and electrically connected to the second needle body 123, so that the headphone plug connected to the first connecting seat 110 can be electrically connected to the wire of the headphone speaker connected to the second connecting seat 120. The second connector is detachably connected to the first connector. When the first locking sleeve 1121 and the second locking sleeve 1221 are close to each other, the first connector can be connected to the second connector. The above-mentioned setting method makes the first connection socket 110 and the second connection socket 120 detachably connected, which is convenient for matching the first connection socket 110 connected with different headphone plugs with the second connection socket 120 connected with different headphone speakers as needed, so that different headphone plugs and headphone speakers can be replaced as needed.

[0047] It should be noted that, in the embodiments of the present application, the detachable connection method of the first and second connectors is not limited, such as, but not limited to, threaded connection, snap connection, pin connection, etc. Among them, the snap connection method is simple to set up and convenient to connect. The snap connection method of the first and second connectors is not limited, such as mutual plugging, mutual abutment, etc. The snap connection method of directly plugging is convenient for assembly and disassembly, which can increase the resistance to separation of the first locking ferrule 1121 and the second locking ferrule 1221, thereby limiting the separation of the first locking ferrule 1121 and the second locking ferrule 1221. The following provides some examples of the mutual abutment method of the first and second connectors.

[0048] Exemplarily, the first locking sleeve 1121 is used to be slidably sleeved within the second locking sleeve 1221. The first connector includes a limiting boss 1123 provided on the outer wall of the first locking sleeve 1121, and the second connector includes a limiting flange 1224 provided on the inner wall of the second locking sleeve 1221. When the first locking sleeve 1121 and the second locking sleeve 1221 slide relative to each other, the limiting boss 1123 can move to the side of the limiting flange 1224 away from the first connecting seat 110. When the first and second connectors are in a locked state, the side of the limiting flange 1224 away from the first connecting seat 110 abuts against the side of the limiting boss 1123 away from the second connecting seat 120; when the first and second connectors are in an open state, the limiting flange 1224 and the limiting boss 1123 are staggered. The second locking sleeve 1221 includes a first connecting sleeve 1222 and a second connecting sleeve 1223. The first connecting sleeve 1222 and the second connecting sleeve 1223 are rotatably matched to each other, so that the first locking sleeve 1121 and the second locking sleeve 1221 can be rotatably matched, so that the first connecting member and the second connecting member can be in an open state and a locked state. In the above-mentioned setting method, locking is achieved by the side of the limiting flange 1224 away from the first connecting seat 110 abutting against the side of the limiting boss 1123 away from the second connecting seat 120, and the opening state and the locking state are changed by the rotatable matching of the first locking sleeve 1121 and the second locking sleeve 1221, which is simple to set. In the locked state, it can effectively prevent the first locking sleeve 1121 and the second locking sleeve 1221 from moving away from each other in the locked state, causing the two to disengage, and the connection is stable.

[0049] In some optional embodiments, a side surface of the limiting boss 1123 away from the second connecting seat 120 extends radially from the first locking sleeve 1121, that is, the side surface of the limiting boss 1123 away from the second connecting seat 120 is perpendicular to the axis of the first locking sleeve 1121. A side surface of the limiting flange 1224 away from the first connecting seat 110 extends radially from the second locking sleeve 1221, that is, the side surface of the limiting flange 1224 away from the first connecting seat 110 is perpendicular to the axis of the second locking sleeve 1221. The side surface of the limiting boss 1123 away from the second connecting seat 120 and the side surface of the limiting flange 1224 away from the first connecting seat 110 are parallel to each other and both are perpendicular to the direction in which the first locking sleeve 1121 and the second locking sleeve 1221 approach and move away from each other, thereby ensuring good stability in the abutment between the limiting boss 1123 and the limiting flange 1224.

[0050] It is understood that the number and distribution of the limiting bosses 1123 and the limiting flanges 1224 are not limited, and the limiting bosses 1123 and the limiting flanges 1224 can be provided as one, two, or more. Optionally, at least two limiting bosses 1123 are provided, for example, two, and the at least two limiting bosses 1123 are evenly distributed along the circumference of the first locking sleeve 1121. Optionally, at least two limiting flanges 1224 are provided, for example, two, and the at least two limiting flanges 1224 are evenly distributed along the circumference of the second locking sleeve 1221.

[0051] Exemplarily, the limiting flange 1224 is annularly arranged along the inner wall of the second locking ferrule 1221, and the limiting flange 1224 is provided with a limiting opening 1225 for the limiting boss 1123 to pass axially through the limiting flange 1224. The setting of the limiting opening 1225 is used to allow the limiting boss 1123 to pass axially when the first locking ferrule 1121 and the second locking ferrule 1221 are matched, so that the limiting boss 1123 can move to the side of the limiting flange 1224 away from the first connecting seat 110, so that the limiting boss 1123 and the limiting flange 1224 can be abutted by further rotation, thereby achieving locking. The limiting flange 1224 is arranged in a ring shape along the inner wall of the second locking sleeve 1221. The limiting flange 1224 has a large circumferential distribution range on the inner wall of the second locking sleeve 1221. The locking angle of the limiting flange 1224 and the limiting boss 1123 is large. In the locked state, the limiting flange 1224 can better abut against the limiting boss 1123 to ensure a more stable connection.

[0052] In an embodiment in which the limiting boss 1123 and the limiting flange 1224 abut against each other for locking, when a certain pressure is generated between the limiting boss 1123 and the limiting flange 1224, the surface of the limiting boss 1123 on the side away from the second connecting seat 120 can effectively abut against the surface of the limiting flange 1224 on the side away from the first connecting seat 110. This can effectively prevent the first connecting seat 110 and the second connecting seat 120 from moving away from each other in the axial direction. On the other hand, it can also increase the friction between the limiting boss 1123 and the limiting flange 1224, so that the first locking sleeve 1121 and the second locking sleeve 1221 can be effectively restricted from relative rotation in the circumferential direction without the application of external rotation force. The pressure generated by the abutment between the two surfaces can achieve self-locking, making the locking state between the first locking sleeve 1121 and the second locking sleeve 1221 more stable.

[0053] For example, the replaceable headphone connector 100 provided in the embodiment of the present application is configured as a replaceable elastic self-locking headphone connector. The second connector further includes an elastic member 1226. The second locking sleeve 1221 is slidably mounted on the outside of the second seat body 121. The elastic member 1226 is mounted between the end of the second locking sleeve 1221 away from the first connecting seat 110 and the second seat body 121. The elastic member 1226 is configured as a telescopic spring, for example. Of course, in other embodiments, an elastic structure such as an elastic washer can also be provided. The elastic member 1226 is used to drive the second locking sleeve 1221 to move in a direction away from the first connecting seat 110. Optionally, a first supporting flange is provided on the inner wall of the end of the second locking sleeve 1221 away from the first connecting seat 110, and the end of the first supporting flange away from the second locking sleeve 1221 is close to the outer wall of the second seat body 121. The outer wall of the second seat body 121 is provided with a second supporting flange, and the end of the second supporting flange away from the second seat body 121 is close to the inner wall of the second locking sleeve 1221. The elastic member 1226 is sleeved between the outer wall of the second seat body 121 and the inner wall of the second locking sleeve 1221, and the elastic member 1226 is supported between the first supporting flange and the second supporting flange. In the above-mentioned setting method, an elastic member 1226 is arranged between the second seat body 121 and the second locking sleeve 1221, so that the second locking sleeve 1221 has a tendency to move in the direction away from the first connecting seat 110 in the locked state, so that the limiting flange 1224 can better press against the limiting boss 1123, thereby achieving self-locking through the pressure generated by the pressing between the two surfaces.

[0054] Optionally, the limiting boss 1123 has a rotation stop point, and a stop portion is provided on the side of the limiting flange 1224 away from the first connecting seat 110. When the limiting boss 1123 rotates to the rotation stop point, the stop portion abuts against the limiting boss 1123 to prevent the limiting boss 1123 from further rotation. The side of the limiting flange 1224 away from the first connecting seat 110 is also recessed with a limiting groove. When the limiting boss 1123 rotates to the rotation stop point, the limiting boss 1123 corresponds to the limiting groove. Under the action of the axial force provided by the elastic member 1226, the limiting boss 1123 is embedded in the limiting groove. In the absence of an external force to offset the axial force provided by the elastic member 1226, the limiting boss 1123 will remain in the limiting groove, thereby preventing the limiting boss 1123 and the limiting flange 1224 from rotating relative to each other, further improving the stability of the connection.

[0055] Furthermore, in an embodiment in which the first locking sleeve 1121 and the second locking sleeve 1221 are rotatably matched, the first connecting sleeve 1222 is threadedly connected to the second connecting sleeve 1223, the limiting flange 1224 is provided at the end of the first connecting sleeve 1222 away from the second connecting sleeve 1223, and the elastic member 1226 is sleeved between the second seat body 121 and the end of the second locking sleeve 1221 away from the first connecting seat 110. In the above-mentioned arrangement, the first connecting sleeve 1222 and the second connecting sleeve 1223 are threadedly connected, which can prevent the first locking sleeve 1121 and the second locking sleeve 1221 from rotating arbitrarily without an external torsional force, thereby effectively preventing the limiting boss 1123 and the limiting flange 1224 from separating from each other, and can ensure that the limiting flange 1224 can better press against the limiting boss 1123 in the locked state, making the locked state more stable.

[0056] In the above-mentioned threaded connection implementation scheme, optionally, the outer wall of the first connecting sleeve 1222 is also provided with anti-slip grooves, so that the first connecting sleeve 1222 can better apply force when the axial length is short, and the first connecting sleeve 1222 and the second connecting sleeve 1223 can be twisted with each other.

[0057] In the embodiment of the present application, when the first connection base 110 and the second connection base 120 are detachably connected, electrical connection is achieved by plugging and fitting the first needle 113 and the second needle 123. The first needle 113 can be optionally configured as a male needle or a female needle, and the second needle 123 can be correspondingly configured as a female needle or a male needle, which facilitates connection and fitting.

[0058] Optionally, the first needle body 113 is a female needle and the second needle body 123 is a male needle. In this embodiment, the second seat body 121 is provided with a male needle protective sleeve 1211, which is arranged around the outside of the second needle body 123 to effectively protect the second needle body 123. The male needle protective sleeve 1211 is used to be slidably mounted between the first needle body 113 and the first locking sleeve 1121. In this arrangement, in an embodiment in which the first locking sleeve 1121 is used to be slidably mounted within the second locking sleeve 1221, the first locking sleeve 1121 is slidably mounted between the male needle protective sleeve 1211 and the first locking sleeve 1121, and the structural stability is good.

[0059] Furthermore, one of the inner wall of the first locking ferrule 1121 and the outer wall of the male needle protection sleeve 1211 is provided with a guide boss 1212, and the other of the inner wall of the first locking ferrule 1121 and the outer wall of the male needle protection sleeve 1211 is provided with a guide groove 1122. For example, the inner wall of the first locking ferrule 1121 is provided with the guide groove 1122, and the outer wall of the male needle protection sleeve 1211 is provided with the guide boss 1212. The guide boss 1212 and the guide groove 1122 are slidably engaged along the axial direction of the first locking ferrule 1121 and the second locking ferrule 1221. The sliding engagement of the guide boss 1212 and the guide groove 1122 enables the first connecting seat 110 and the second connecting seat 120 to move along a preset direction when approaching and moving away from each other, and the first connecting seat 110 and the second connecting seat 120 have good correspondence when connected and are easy to operate. At the same time, the cooperation between the guide boss 1212 and the guide groove 1122 also plays a limiting role in the locked state, thereby preventing radial shaking between the first connecting seat 110 and the second connecting seat 120, and the locked state is more stable.

[0060] In a second aspect, an embodiment of the present application provides an earphone structure, comprising an earphone plug, an earphone speaker, and the replaceable earphone connector 100 provided in the embodiment of the first aspect. The earphone plug is connected to an end of a first conductive wire that is away from the first needle 113, and the earphone speaker is connected to an end of a second conductive wire that is away from the second needle 123.

[0061] It is understood that since the first conductive wire is disposed through the first base body 111, the end of the first conductive wire away from the first needle 113 can be located within or extend from the first base body 111. A mounting slot can optionally be provided in the first base body 111 away from the first needle 113. During the production process, the headphone plug can be secured within the mounting slot to achieve electrical connection between the end of the first conductive wire away from the first needle 113 and the headphone plug. A second conductive wire is disposed through the second base body 121, and the end of the second conductive wire away from the second needle 123 can extend from the second base body 121. During the production process, the end of the second conductive wire away from the second needle 123 can be connected to a headphone cable for connecting to a headphone speaker through an injection molding process or a wire connector, or the second connecting wire can be integrated with the headphone cable for connecting to the headphone speaker to achieve electrical connection between the end of the second conductive wire away from the second needle 123 and the headphone speaker.

[0062] The working principle of the replaceable headphone connector 100 provided in the embodiment of the present application is as follows:

[0063] One end of the first conductive wire is connected to the first needle 113, and the other end is used to connect to the headphone plug. One end of the second conductive wire is connected to the second needle 123, and the other end is used to connect to the headphone speaker. The plugging and matching of the first needle 113 and the second needle 123 enables the wires of the headphone plug and the headphone speaker to communicate. The first locking ferrule 1121 is arranged outside the first needle 113, and the second locking ferrule 1221 is arranged outside the second needle 123, which can better protect the needles. The first locking ferrule 1121 is used to slidably match with the second locking ferrule 1221, allowing the first locking ferrule 1121 and the second locking ferrule 1221 to move relative to each other along the axis, so that the first connecting base 110 and the second connecting base 120 can move closer to and away from each other. The second needle 123 is used to plug and match with the first needle 113. When the first connecting base 110 and the second connecting base 120 are close to each other, the first needle 113 can plug into the second needle 123 and be electrically connected. The second connector is detachably connected to the first connector, and when the first locking sleeve 1121 and the second locking sleeve 1221 are brought into proximity, the first connector can be connected to the second connector. The first connector 110 and the second connector 120 are detachably connected, making it easy to pair the first connector 110, which is connected to a different headphone plug, with the second connector 120, which is connected to a different headphone speaker, as needed. This allows for replacement of different headphone plugs and headphone speakers as needed.

[0064] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
