[0001] The present application relates to the field of electronic technology, and in particular to a ejector pin and an electronic device. Background Art

[0002] Ejector pins are components used to achieve electrical connections. They are usually used in electronic devices, especially in situations where frequent plugging and unplugging is required or where connection stability is maintained in a dynamic environment. In related technologies, the connection between the needle tip of the ejector pin and the conductive component is usually point-to-point, and the contact area between the needle tip and the conductive component is small. The small contact area results in insufficient sensitivity of ejector pin control. Utility Model Content

[0003] The embodiments of the present application provide an ejector pin and an electronic device. The ejector pin has a larger contact area, which can improve the sensitivity of ejector pin control.

[0004] In a first aspect, an embodiment of the present application provides a ejector pin, comprising:

[0005] The needle tube comprises a receiving cavity and a first opening which are communicated with each other;

[0006] A connecting piece, which is covered on the needle tube and can move relative to the needle tube;

[0007] An elastic member is passed through the first opening and is partially disposed in the accommodating cavity. The elastic member is elastically connected between the needle tube and the connecting member.

[0008] In one embodiment, the connecting member includes a flat plate and a first annular wall, the flat plate covers the needle tube, the elastic member is connected to the flat plate, and the first annular wall is connected to a side of the flat plate facing the needle tube and is sleeved on the needle tube.

[0009] In one embodiment, the outer diameter of the flat plate is greater than the outer diameter of the first annular wall.

[0010] In one embodiment, the first annular wall includes a first surrounding portion and a first connecting portion, and the first surrounding portion is disposed between the flat plate and the first connecting portion;

[0011] The needle tube includes a second annular wall surrounding the accommodating cavity, the second annular wall includes a second surrounding portion and a second connecting portion, and the second surrounding portion is connected to a side of the second connecting portion facing the flat plate;

[0012] When the connecting member moves away from the needle tube limit position, the first connecting portion abuts against the second connecting portion, so that the connecting member is connected to the needle tube limit position.

[0013] In one embodiment, the first connecting portion is arranged from the first surrounding portion toward the needle tube, the outer diameter of the second connecting portion is larger than the outer diameter of the second surrounding portion, and when the connecting member moves toward a limit position away from the needle tube, the first connecting portion abuts against a side of the second connecting portion away from the flat plate.

[0014] In one embodiment, the first connecting portion is inclined from the first surrounding portion toward the needle tube and away from the flat plate.

[0015] In one embodiment, the first connecting portion includes a first inclined surface toward the flat plate, and the first inclined surface is inclined from the first surrounding portion toward the needle tube and away from the flat plate; the second connecting portion includes a second inclined surface arranged corresponding to the first inclined surface, and the second inclined surface is inclined from the second surrounding portion toward the flat plate and away from the accommodating cavity.

[0017] In one embodiment, the needle tube includes a bottom plate and a protrusion disposed opposite to the first opening, and the protrusion is convexly disposed on a side of the bottom plate away from the first opening.

[0021] The connector cover of the ejector pin of the embodiment of the present application is arranged on the needle tube, that is, the connector covers the needle tube in structure, so the size of the connector is larger than that of the needle tube, and the surface area of ​​the connector is larger. When the ejector pin is used as a connector, the contact area with the conductive component during electrical connection is increased. The larger contact area increases the friction force, and the connector is less likely to move or fall off due to vibration, impact or other external forces, which can provide a more stable electrical connection. In addition, the larger area of ​​the connector can provide a more uniform pressure distribution to reduce local damage to the conductive component. Moreover, the ejector pin can be used as a touch button or a press button of an electronic device such as a Bluetooth headset. Since the contact area of ​​the ejector pin connector is larger, the user can perform touch or press operations on a larger surface, which helps the user to locate the button more easily and reduce misoperation. The larger contact area also makes the ejector pin more sensitive when transmitting signals. Even a slight touch or press can be accurately recognized and transmitted, thereby quickly triggering operations such as volume adjustment, song switching, and pause, thereby improving the sensitivity of control.

[0028] The present application embodiment provides a ejector pin, which is described below in conjunction with the accompanying drawings. Figure 1 , Figure 2 and Figure 3 . Figure 1 A schematic diagram of the structure of the ejector pin provided in the embodiment of the present application, Figure 2 for Figure 1 The cross-sectional view of the ejector pin along the AA direction is shown. Figure 3 for Figure 1 Schematic diagram of the structure of the connecting piece and needle tube of the ejector pin shown.

[0029] The ejector pin 10 provided in the embodiment of the present application includes a needle tube 100, a connecting piece 200 and an elastic piece 300. The needle tube 100 includes a accommodating cavity 110 and a first opening 120 which are interconnected. The connecting piece 200 is covered on the needle tube 100 and can move relative to the needle tube 100. The elastic piece 300 is passed through the first opening 120 and is partially disposed in the accommodating cavity 110. The elastic piece 300 is elastically connected between the needle tube 100 and the connecting piece 200.

[0030] The needle tube 100 is the main body of the connector, and the needle tube 100 includes a receiving cavity 110 and a first opening 120. The elastic member 300 is partially disposed in the receiving cavity 110 and passes through the first opening 120 to connect the needle tube 100 and the connecting member 200, so that a certain elastic connection can be maintained between the needle tube 100 and the connecting member 200.

[0031] The ejector pin 10 of this embodiment can be used as a connector. Specifically, the first conductive component is connected through the connector 200, and the second conductive component is connected through the needle tube 100, so that the electrical connection between the two conductive components can be achieved through one ejector pin 10. When the ejector pin 10 is in use, the connector 200 abuts against the conductive component, the elastic member 300 is compressed, and the elastic member 300 has an elastic force to restore its original shape, so that the connector 200 can exert a stable pressure on the conductive component, keep the connector 200 in contact with the conductive object, and achieve electrical connection between the ejector pin 10 and the conductive component.

[0032] The connector 200 is covered on the needle tube 100, that is, the connector 200 structurally covers the needle tube 100. Therefore, the size of the connector 200 is larger than that of the needle tube 100, so that the surface area of ​​the connector 200 is larger, thereby increasing the contact area with the conductive component during electrical connection. The larger contact area increases the friction, and the connector 200 is less likely to move or fall off due to vibration, impact or other external forces, so that a more stable electrical connection can be provided. Moreover, the larger area of ​​the connector 200 can provide a more uniform pressure distribution to reduce local damage to the conductive component.

[0033] The ejector pin 10 of this embodiment can also be used as a touch button or a push button. For example, the needle tube can be fixedly connected to the circuit board, and the connector 200 can abut against a metal plate, that is, the ejector pin connects the circuit board and the metal plate. When the user touches the metal plate or presses the metal plate with his hand, a signal change will occur, and the ejector pin will transmit the signal change to the circuit board. The circuit board recognizes that the user has touched or pressed the button, so that operations such as switching songs, pausing, and adjusting the volume can be performed. The connector 200 of this embodiment has a larger contact area, allowing the user to press on a larger surface, which helps the user to locate the button more easily, improves the accuracy of touching or pressing, and reduces misoperation. The larger contact area of ​​the connector also helps the ejector pin to be more sensitive in transmitting signals. Even a slight touch or press can be accurately recognized and transmitted, thereby quickly triggering operations such as volume adjustment, switching songs, pausing, etc., improving the sensitivity of control.

[0034] In some embodiments, the connecting member 200 includes a flat plate 210 and a first annular wall 220 . The flat plate 210 covers the needle tube 100 . The first annular wall 220 is connected to the side of the flat plate 210 facing the needle tube 100 and is sleeved on the needle tube 100 .

[0035] Among them, the first annular wall 220 of the connecting member 200 is sleeved on the needle tube 100, so that the connecting member 200 can move axially relative to the needle tube 100, and the position of the connecting member 200 in the entire ejector pin 10 system is more stable, reducing the displacement caused by force.

[0036] Exemplarily, the flat plate 210 of the connector 200 is flush and has a large area as an interface for contacting the conductive object, which provides greater structural stability for the connector 200, helps to resist displacement or deformation caused by external forces, and also helps to distribute pressure more evenly, which helps to improve the stability of the electrical connection and the conductivity. It helps to improve the stability and conductivity of the contact. The elastic member 300 is connected to the flat plate 210, which can provide a continuous holding force to ensure a stable connection between the flat plate 210 and the conductive object. The elastic member 300 can also absorb and buffer dynamic loads caused by vibration or impact, reducing the risk of disconnection of the connection.

[0037] In another example, the flat plate 210 of the connector 200 can be used as a user pressing interface, which is flat and has a large area, providing a larger operating area for the user and improving the trigger sensitivity of the key. The flat plate 210 design can adapt to different pressing methods, including fingertip touch, fingertip press, etc., increasing the flexibility of use. The smooth surface of the flat plate 210 provides a more comfortable pressing feeling, improving the user experience.

[0038] In some embodiments, the outer diameter of the flat plate 210 is greater than the outer diameter of the first annular wall 220. That is, the orthographic projection of the first annular wall 220 on the flat plate 210 is located inside the flat plate 210, and the periphery of the flat plate 210 exceeds the annular wall. In this embodiment, the outer diameter of the flat plate 210 is greater than the outer diameter of the first annular wall 220, so the flat plate 210 can cover a larger area. The first annular wall 220 is sleeved on the needle tube 100, and the size of the first annular wall 220 can match the size of the needle tube 100, and a relatively small outer diameter can be designed, so that the structure of the entire ejector pin 10 is more compact, saving installation space, and can be flexibly used in a small space.

[0039] In some embodiments, the first annular wall 220 includes a first surrounding portion 221 and a first connecting portion 225, and the first surrounding portion 221 is arranged between the flat plate 210 and the first connecting portion 225; the needle tube 100 includes a second annular wall 130 surrounding the accommodating cavity 110, and the second annular wall 130 includes a second surrounding portion 131 and a second connecting portion 135, and the second surrounding portion 131 is connected to the second connecting portion 135 facing the side of the flat plate 210; when the connecting member 200 moves away from the needle tube 100, the first connecting portion 225 abuts against the second connecting portion 135 to limit the connection between the connecting member 200 and the needle tube 100.

[0040] When the connector 200 moves in a direction away from the needle tube 100, the first connecting portion 225 abuts against the second connecting portion 135, realizing a position-limiting connection between the connector 200 and the needle tube 100, thereby preventing the connector 200 from falling off the needle tube 100. Therefore, the connector 200 can move axially relative to the needle tube 100, but through the interaction between the first connecting portion 225 and the second connecting portion 135, the axial movement is limited to a certain range, thereby ensuring the stability of the electrical connection.

[0041] In some embodiments, the first connecting portion 225 is arranged from the first surrounding portion 221 toward the needle tube 100, the outer diameter of the second connecting portion 135 is larger than the outer diameter of the second surrounding portion 131, and when the connecting member 200 moves toward a limited position away from the needle tube 100, the first connecting portion 225 abuts against the side of the second connecting portion 135 away from the plate 210.

[0042] Among them, the first connecting portion 225 is arranged from the first surrounding portion 221 toward the needle tube 100, so that the first connecting portion 225 protrudes toward the needle tube 100 relative to the first surrounding portion 221, and the outer diameter of the second connecting portion 135 is larger than the outer diameter of the second surrounding portion 131, so that the second connecting portion 135 protrudes toward the first surrounding portion 221 relative to the second surrounding portion 131. When the connecting member 200 moves in a direction away from the needle tube 100, the first connecting portion 225 protruding toward the needle tube 100 can abut against the second connecting portion 135 protruding toward the second surrounding portion 131, thereby limiting the continued movement of the connecting member 200 and preventing it from excessive movement or detachment.

[0043] In some embodiments, the first connection portion 225 is tilted from the first surrounding portion 221 toward the needle tube 100 and away from the flat plate 210. The tilted setting of the first connection portion 225 allows it to contact the second connection portion 135 at a certain angle, which can expand the contact area between the first connection portion 225 and the second connection portion 135, and can provide greater friction, thereby improving the limiting holding force, and when the connector 200 is subjected to tension, the tilted first connection portion 225 can better disperse these forces, prevent the connector 200 from being separated from the needle tube 100 when subjected to tension, and improve the reliability of the electrical connection.

[0044] In some embodiments, please refer to Figure 4 and Figure 5 , Figure 4 for Figure 3 The schematic diagram of the partial structure of the ejector pin is shown in FIG. Figure 5 for Figure 4 The first connecting portion 225 includes a first inclined surface 226 facing the plate 210, and the first inclined surface 226 is inclined from the first surrounding portion 221 toward the needle tube 100 and away from the plate 210; the second connecting portion 135 includes a second inclined surface 136 corresponding to the first inclined surface, and the second inclined surface 136 is inclined from the second surrounding portion 131 toward the plate 210 and away from the accommodating cavity 110.

[0045] Among them, when the first connecting part 225 abuts against the second connecting part 135, the first inclined surface 226 of the first connecting part 225 and the second inclined surface 136 of the second connecting part 135 abut against each other, so that the connecting piece 200 can be limited. This inclined surface matching can provide a smooth transition and good contact between the connecting piece 200 and the needle tube 100, and the assembly and disassembly process between the connecting piece 200 and the needle tube 100 is also smoother. In addition, the inclined surface matching can also increase the contact area between the connecting piece 200 and the needle tube 100 to increase the contact friction, and can also better adapt to the pulling force from different directions, which helps to improve the stability of the limit.

[0046] In some embodiments, the second connecting portion 135 includes an inner wall 137 facing the accommodating cavity 110 , and the inner wall 137 includes a top segment 138 away from the second surrounding portion 131 , and the inner diameter of the top segment 138 gradually increases in a direction away from the second surrounding portion 131 .

[0047] It can be understood that the elastic member 300 is connected between the needle tube 100 and the connecting member 200. When the flat plate 210 of the connecting member 200 is pressed, the elastic member 300 will shrink axially toward the needle tube 100 due to the pressure, but the direction of the pressure may be tilted to a certain extent. Therefore, the elastic member 300 may also be tilted to a certain extent when shrinking. The top section 138 is the transition area between the accommodating space formed by the connecting member 200 and the needle tube 100. The inner diameter of the top section 138 gradually increases. For example, the top section 138 is designed as a slope, which can help guide the elastic member 300 to shrink along the axial direction of the needle tube 100, and maintain the correct position and movement direction of the elastic member 300 even in the case of pressure tilt.

[0048] In some embodiments, the needle tube 100 includes a bottom plate 140 and a protrusion 150 disposed opposite to the first opening 120 . The protrusion 150 is protruded from a side of the bottom plate 140 away from the first opening 120 .

[0049] The bottom plate 140 of the needle tube 100 is provided with a protrusion 150, which is designed to be inserted into the mounting groove of another conductive object to achieve electrical connection with the conductive component. The size of the protrusion 150 is smaller than that of the bottom plate 140. The smaller protrusion 150 occupies less space and can be flexibly arranged in the mounting groove on the conductive component, which facilitates the installation and positioning of the ejector pin 10.

[0050] In some embodiments, a conical groove 170 is provided on the side of the bottom plate 140 facing the first opening 120 , and the size of the conical groove 170 gradually decreases in the direction away from the first opening 120 . One end of the elastic member 300 abuts against the conical groove 170 , and the other end of the elastic member 300 abuts against the flat plate 210 .

[0051] An embodiment of the present application provides an electronic device, including a first conductive component, a second conductive component and a pin 10 of any of the above embodiments, wherein the connector 200 is used to electrically connect the first conductive component, and the needle tube 100 is used to electrically connect the second conductive component.

[0052] The electronic device can use the ejector pin 10 to electrically connect the first conductive component and the second conductive component. Specifically, the first conductive component is connected through the connector 200 such as the flat plate 210, and the second conductive component is connected through the needle tube 100 such as the protrusion 150, so that the electrical connection of the two conductive components can be achieved through one ejector pin 10, which helps to simplify the design and reduce space occupation. In addition, since the ejector pin 10 is easy to operate, the conductive components can be quickly disconnected and reconnected, reducing maintenance time and complexity.

[0053] Moreover, the ejector pin 10 can be used as a touch button or a press button of an electronic device such as a Bluetooth headset. For example, the protrusion 150 of the needle tube 100 can be fixedly connected to a circuit board, and the flat plate 210 of the connector 200 can abut against a metal plate, that is, the ejector pin 10 connects the circuit board and the metal plate. When the user touches the metal plate or presses the metal plate with his hand, a signal change will occur, and the ejector pin will transmit the signal change to the circuit board. The circuit board recognizes that the user has touched or pressed the button, so that operations such as switching songs, pausing, and adjusting the volume can be performed. Since the flat plate 210 of the connector 200 of this embodiment has a large contact area, the user is allowed to press on a larger surface, which helps the user to locate the button more easily, improves the accuracy of touching or pressing, and reduces misoperation. Moreover, the large contact area of ​​the connector also helps the signal detection to be more sensitive. Even a slight touch or press can be accurately recognized and transmitted, thereby triggering operations such as volume adjustment, switching songs, pausing, etc., which improves the sensitivity of control. Therefore, the ejector pin 10, as a touch button or a push button, provides the user with a fast-response, stable and reliable electrical connection method through its mechanical trigger mechanism, and is very suitable for use in electronic devices with relatively limited space or portable electronic devices.

[0054] The ejector pin and the electronic device provided in the embodiments of the present application are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present application.
