Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connectors, in particular to a connector assembly, a male connector and an electronic device. BACKGROUND

[0002] With the development of technology, electronic devices such as mobile phones, tablets, laptops and keyboards are increasingly widely used in daily life. Spring pins and other connectors are often used in electronic devices to transmit current, signals and other information. The spring pin connector includes a male end and a female end. When the male end and the female end are in contact, electrical connection can be achieved to transmit current and signals. However, during use, the male end and the female end of the spring pin connector are prone to misalignment, which causes poor contact between the male end and the female end, affecting the transmission of current and signals. SUMMARY

[0003] The present application provides a connector assembly, a male connector and an electronic device, which are used to improve the stability of the connection between the male connector and the female connector.

[0004] The first aspect of the present application provides a connector assembly, which comprises:

[0005] at least one female connector, the female connector comprising a guide portion;

[0006] at least one male connector, the male connector comprising a first housing, a first connecting piece and a first elastic piece, the first housing having a first accommodating cavity, the first elastic piece being located in the first accommodating cavity, and the first elastic piece being elastically connected with the first connecting piece;

[0007] wherein the first connecting piece comprises a first connecting portion and a first limiting portion, the first limiting portion being arranged on the outer periphery of the first connecting portion, the first limiting portion being located in the first accommodating cavity, and the first connecting portion being capable of extending out of the first accommodating cavity and cooperating with the guide portion;

[0008] the first housing comprising a second limiting portion for abutting against the first limiting portion, at least one of the first limiting portion and the second limiting portion being provided with an arc-shaped guide surface, the first limiting portion and the second limiting portion abutting against each other through the guide surface, and the first connecting piece and the second limiting portion having a first gap therebetween in the radial direction of the first connecting piece.

[0009] The arc-shaped guide surface is arranged, the first connecting piece can move along the guide surface relative to the first shell, the force position of the first connecting piece changes when the axis of the male connector is not coincident with the axis of the female connector or the first connecting piece is installed askew, the first connecting piece can move along the guide surface when moving along the axial direction of the first shell, the first connecting piece swings through the movement along the guide surface, and the first connecting piece swings towards the center of the female connector. The first gap is used for providing a space for the swing of the first connecting piece, and the possibility of interference between the first connecting piece and the first shell during the swing is reduced. Through the arrangement of the arc-shaped guide surface and the first gap, the first connecting piece can swing, the swing of the first connecting piece is used for rectification, and therefore the stability of the connection between the male connector and the female connector is improved, and the possibility of poor contact of the connector assembly is reduced.

[0010] In a possible implementation, the guide surface is arranged on the first limiting portion, and when the male connector is not electrically connected with the female connector, the guide surface abuts against the second limiting portion, or;

[0011] The guide surface is arranged on the second limiting portion, and when the male connector is not electrically connected with the female connector, the guide surface abuts against the first limiting portion.

[0012] The contact area between the first limiting portion and the second limiting portion is reduced, and therefore the relative movement of the first limiting portion and the second limiting portion along the guide surface is facilitated. When the male connector and the female connector are misaligned or the first connecting piece is installed askew, the first connecting piece can swing, the first connecting piece moves towards the center of the female connector, rectification is performed, and therefore the stability of the connection between the male connector and the female connector is improved.

[0013] In a possible implementation, the first limiting portion is provided with a first guide surface, the second limiting portion is provided with a second guide surface, and the first guide surface and the second guide surface abut against each other.

[0014] The contact between the first limiting portion and the second limiting portion is surface contact, and the contact area therebetween is relatively large, which is beneficial to improving the stability of the swing of the first connecting piece relative to the first shell, and therefore the connection stability of the male connector and the female connector is improved.

[0015] In a possible implementation, the guide surface is a spherical surface.

[0016] The first guide surface and the second guide surface can be spherical surfaces, which can be used to enable the first connecting piece to swing in different directions. When the male connector and the female connector are misaligned in different directions or the first connecting piece is inclined in different directions, the first connecting piece can swing to the center of the second connecting end, thereby facilitating the stability of the connection between the male connector and the female connector.

[0017] When the guide surface is arranged at the first limiting portion, the guide surface is an outer spherical surface, and when the guide surface is arranged at the second limiting portion, the guide surface is an inner spherical surface. Specifically, the guide surface is not a complete spherical surface, but a spherical-like surface, i.e., the guide surface can be equivalent to a part of a complete spherical surface.

[0018] In a possible implementation, the size of the first gap is 0.2 mm to 1 mm in the radial direction of the male connector.

[0019] Unlike the error gap caused by insufficient fitting accuracy, the scheme provided in the embodiments of the application can leave space for the swing of the first connecting piece by arranging the first gap, thereby reducing the possibility of contact between the first connecting piece and the second limiting portion during the swing, reducing the possibility of interference between the first connecting piece and the first housing during the swing, facilitating the stability of the movement of the first connecting piece, and reducing the possibility of deformation of the first connecting piece under pressure.

[0020] In a possible implementation, one of the first connecting portion and the guide portion has a protruding portion, and the other has a recessed portion, and at least part of the protruding portion can extend into the recessed portion.

[0021] By such a design, the relative position accuracy of the male connector and the female connector can be improved when the male connector and the female connector are fitted, thereby facilitating the stability of the contact between the male connector and the female connector, and thereby reducing the possibility of poor contact.

[0022] In a possible implementation, the recessed portion is arranged at the guide portion, and the protruding portion is arranged at the first connecting portion.

[0023] The surface of the recessed portion in contact with the protruding portion is an arc surface, and the surface of the protruding portion in contact with the recessed portion is an arc surface.

[0024] By such a design, when the male connector and the female connector are misaligned, the first connecting piece is in contact with the inner wall of the recess, at this time, the force direction of the first connecting piece and the axial direction of the male connector have an included angle, so that the first connecting piece can move along the guide surface relative to the first shell, so that the first connecting piece swings, and at the same time, as the male connector and the female connector approach each other, the first connecting piece moves along the inner wall of the recess to the center position of the recess, so that the male connector can be in contact with the center position of the female connector, thereby improving the stability of the electrical connection.

[0025] In a possible implementation, the surface of the recess in contact with the protrusion is a spherical surface, and the surface of the protrusion in contact with the recess is a spherical surface.

[0026] The spherical surfaces of the protrusion and the recess in contact with each other can make the first connecting piece receive forces in different directions when the male connector and the female connector have errors in different directions along the fitting, so that the first connecting piece swings in different directions, and the first connecting piece approaches the center position of the second connecting end through swinging, thereby facilitating the improvement of the stability of the connection between the male connector and the female connector.

[0027] In a possible implementation, the male connector comprises a second elastic piece, and the second elastic piece fills the first gap.

[0028] During the assembly of the male connector, when the first connecting piece is inclined, the first connecting piece can extrude the second elastic piece, and the second elastic piece deforms. The restoring force generated by the deformation of the second elastic piece can act on the first connecting piece, so that the first connecting piece moves in the opposite direction of the inclination, so that the first connecting piece is corrected, thereby improving the relative position accuracy of the first connecting piece and the first shell, thereby reducing the possibility of the first connecting piece being inclined during installation, or reducing the degree of inclination of the axis of the first connecting piece relative to the axis of the first shell. During the approach of the male connector and the female connector, the second elastic piece can provide buffering when the first connecting piece swings. The first connecting piece can not be in direct contact with the first shell, thereby reducing the friction between the first connecting piece and the first shell, and further reducing the possibility of damage to the first connecting piece, thereby facilitating the extension of the service life of the first connecting piece and the connector assembly.

[0029] In a possible implementation, the first connecting piece further comprises a second connecting portion connected with the first limiting portion, and the first connecting portion and the second connecting portion are located on two sides of the first limiting portion.

[0030] The first elastic piece is sleeved inside the second connecting portion, or the first elastic piece is sleeved outside the second connecting portion.

[0031] By such a design, the contact area of the first connecting piece and the first elastic piece can be further increased, and the possibility of the first elastic piece being separated from the first connecting piece can be reduced. The first elastic piece can abut against the bottom wall of the cavity in the axial direction of the male connector. Meanwhile, during the movement of the first connecting piece, the deformation of the first elastic piece can be guided, thereby improving the stability of the deformation and movement of the first elastic piece, and further improving the stability of the electrical connection between the male connector and the female connector, and reducing the possibility of poor contact.

[0032] In a possible implementation, along the radial direction of the first connecting piece, the second connecting part and the side wall of the first accommodating cavity have a second gap, and the size of the second gap is 0.2 mm to 1.5 mm.

[0033] By providing the second gap between the second connecting part and the inner wall of the first accommodating cavity, when the first connecting piece swings, the first connecting piece can be inclined relative to the axial direction of the male connector to utilize the swing of the first connecting piece to move the first connecting piece to the central position of the female connector, thereby improving the stability of the electrical connection between the male connector and the female connector.

[0034] In a possible implementation, the female connector comprises a second housing, a second connecting piece and a third elastic piece, the second housing has a second accommodating cavity, the third elastic piece is located in the second accommodating cavity, and the third elastic piece is elastically connected with the second housing and the second connecting piece.

[0035] The second connecting piece comprises a third limiting part and the guide part, the third limiting part is arranged on the outer periphery of the guide part, the second housing comprises a fourth limiting part for abutting against the third limiting part, at least one of the third limiting part and the fourth limiting part is provided with an arc surface, the guide surface is an arc surface, the third limiting part and the fourth limiting part abut against each other through the arc surface, and along the radial direction of the second connecting piece, the second connecting piece and the fourth limiting part have a third gap.

[0036] When the male connector and the female connector are connected, as the male connector and the female connector approach each other, the second connecting piece can be driven to move relative to the second housing, and the third elastic piece can be deformed. The restoring force generated by the deformation of the third elastic piece can act on the second connecting piece, so that the second connecting piece has a movement trend in the direction of approaching the male connector, thereby improving the stability of the electrical connection between the male connector and the female connector, and more meeting the actual use requirements.

[0037] The second aspect of the present application provides a male connector, the male connector comprising a first housing, a first connecting member and a first elastic member, the first housing having a first accommodating cavity, the first elastic member being located in the first accommodating cavity, and the first elastic member being elastically connected with the first connecting member;

[0038] The first connecting member comprises a first connecting portion and a first limiting portion, the first limiting portion being arranged on the outer periphery of the first connecting portion, the first limiting portion being located in the first accommodating cavity, and the first connecting portion being capable of extending out of the first accommodating cavity.

[0039] The first housing comprises a second limiting portion for abutting against the first limiting portion, at least one of the first limiting portion and the second limiting portion being provided with an arc-shaped guide surface, the first limiting portion and the second limiting portion abutting against each other through the guide surface, and the first connecting member and the second limiting portion having a first gap in the radial direction of the first connecting member.

[0040] The third aspect of the present application provides an electronic device, the electronic device comprising a connector assembly, the connector assembly being any one of the connector assemblies described above.

[0041] In a possible implementation, the electronic device comprises a pen tip structure and a pen shaft which are movably connected, one of the male connector and the female connector being arranged on the pen tip structure, and the other being arranged on the pen shaft structure, the first connecting member of the male connector and the guide portion of the female connector being capable of contacting each other in the relative movement of the pen tip structure and the pen shaft.

[0042] In a possible implementation, the electronic device comprises a tablet computer and a keyboard, one of the male connector and the female connector being arranged on the tablet computer, and the other being arranged on the keyboard, the male connector and the female connector being electrically connected for signal transmission.

[0043] In a possible implementation, one of the tablet computer and the keyboard is provided with a limiting protrusion, and the other is provided with a limiting recess, the limiting protrusion being capable of extending into the limiting recess.

[0044] By arranging a plurality of male connectors and female connectors, the stability of the connector assembly and the signal transmission efficiency can be improved, and the actual use requirements can be better met.

[0045] In a possible implementation, one of the tablet computer and the keyboard is provided with a magnetic member, and the other is provided with a matching member, the magnetic member being used for magnetic attraction connection with the matching member.

[0046] By setting the magnetic member and the matching member, the limiting protrusion and the limiting recess, the male connector and the female connector can be pre-positioned, so as to facilitate improving the connection precision of the two.

[0052] In a possible implementation, one of the first main body part and the second main body part is provided with a limiting protrusion, and the other is provided with a limiting recess, the limiting protrusion being capable of extending into the limiting recess.

[0053] In a possible implementation, one of the first main body part and the second main body part is provided with a magnetic member, and the other is provided with a matching member, the magnetic member being used for magnetic adsorption connection with the matching member.

[0088] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0089] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0090] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0091] The conductive male head of the Pogo Pin connector is a spring probe formed by three basic components, i.e. a needle shaft, a spring and a needle tube, through precise instrument riveting and pre-pressing. The Pogo Pin connector has good corrosion resistance, mechanical properties and electrical properties, and can usually play a role in current and signal transmission. The needle shaft shrinks a certain length under the extrusion of external force, and the spring inside the needle tube can act on the needle shaft to improve the stability of the connection between the needle shaft and the conductive female head. The Pogo Pin connector assembly has good resilience and a large working stroke. The Pogo Pin connector assembly can be used in electronic devices, including but not limited to mobile phones, tablets, laptops, styluses, keyboards, etc.

[0092] Taking the electronic device as a stylus 5, Figure 1 is a structural schematic diagram of the electronic device as the stylus 5. As Figure 1 shown, the stylus 5 includes a pen barrel 52 and a pen tip structure 51 mounted on the pen barrel 52. Figure 2 is Figure 1 a partial cross-sectional view, in which the stylus is in an initial state. As Figure 2 shown, the stylus 5 further includes a connector assembly, the connector assembly including a male connector 1 and a female connector 2, the male connector 1 being a male end of the connector assembly, the female connector 2 being a female end of the connector assembly, the tail end of the male connector 1 and the tail end of the second connector assembly 2 being respectively led out through wires. The male connector and the female connector are respectively mounted on the pen tip structure 51 and the pen barrel 52. In one specific embodiment, the male connector 1 is mounted on the pen barrel 52, and the female connector 2 is mounted on the pen tip of the pen tip structure 51. In other embodiments, the male connector 1 is mounted on the pen tip, and the female connector 2 is mounted on the pen barrel. When the male connector 1 and the female connector 2 are electrically connected, the stylus 5 can be used to transmit signals, i.e. the signals of the pen tip and the pen barrel 52 can be transmitted through the connector assembly to identify the information input by the user through the stylus 5.

[0093] The male connector 1 includes a first housing 11, a first connecting piece 12 and a first elastic piece 13, the first connecting piece 12 and the first elastic piece 13 being mounted on the first housing 11 and being movable along the axial direction of the male connector 1. The female connector 2 and the first connecting piece 12 of the male connector 1 can be made of conductive materials, such as metal, graphite, alloy materials, etc. The material of the first connecting piece 12 can be the same as that of the first housing 11, and the first housing 11 can be electrically connected with the first connecting piece 12 as a terminal for transmitting current and signals.

[0094] In the initial state, as Figure 2 shown, the first connecting piece 12 of the male connector 1 has a gap with the female connector 2, and the two cannot achieve signal transmission.

[0095] Figure 3 for Figure 1 A diagram showing the stylus in working mode. Figure 4 for Figure 3 A partial cross-sectional view of the stylus 5, showing the stylus 5 in a working state. (See attached image.) Figure 3 As shown, the stylus 5 is used to input information into the tablet computer 6. Figure 4 As shown, the pen tip structure 51 can be threaded onto the pen barrel 52. By rotating the pen tip structure 51, the pen tip structure 51 and the pen barrel 52 can move relative to each other along the axial direction of the stylus 5. Alternatively, the pen tip structure 51 can also be slidably connected to the pen barrel 52, allowing them to move relative to each other along the axial direction of the stylus 5. During this relative movement of the pen tip structure 51 and the pen barrel 52 along the axial direction of the stylus 5, the male connector 1 and the female connector 2 can be electrically connected or disconnected. Figure 4 As shown, when the stylus 5 is in working condition, it electrically connects the male connector 1 and the female connector 2.

[0096] Normally, during the assembly of the stylus 5, the female connector 2 is first installed on the pen tip structure 51, serving as the pen tip. The male connector 1 is then installed on the pen barrel 52, and the pen tip structure 51 and pen barrel 52 are assembled together. Ideally, the axis of the male connector 1 (which can typically be approximated as the axis of the first housing 11), the axis of the female connector 2, and the axis of the first connector 12 are parallel and located on the same straight line. However, during the assembly process, due to the influence of fitting precision and the fitting tolerances between components, the positions of each component may shift within a certain range.

[0097] For example, such as Figure 4 As shown, during the assembly process, the axis of the male connector 1 does not coincide with the axis of the female connector 2, that is, the two are misaligned. Figure 4 A schematic diagram illustrating the misalignment of the male and female connectors during the assembly process of the stylus 5 is shown. Figure 4 As shown, the axial direction of the female connector 2 does not coincide with the axial direction of the male connector 1, resulting in misalignment. When this misalignment occurs, the first connector 12 may fail to make contact with the female connector 2, or... Figure 4 As shown, the male connector 1 and the female connector 2 are in contact at their edges, which can easily lead to poor contact in the connector assembly and affect signal transmission.

[0098] Figure 5 This is a schematic diagram showing the first connector 12 being installed incorrectly during assembly. Figure 6 It shows Figure 5 A schematic diagram showing the electrical connection between male connector 1 and female connector 2. Figure 6As shown, as the male connector 1 and the female connector 2 approach each other, the first shell 11 and the first connecting piece 12 are in radial contact, causing interference between the first shell 11 and the first connecting piece 12, hindering the axial movement of the first connecting piece 12 along the first shell 11, and the first connecting piece 12 is pressed by the female connector 2, causing the first connecting piece 12 to be easily bent, not only affecting the stability of the connector assembly connection, but also easily causing damage to the first connecting piece 12, affecting the service life of the connector assembly. At the same time, when the outer shell of the pen tip structure 51 is transparent, the bending of the first connecting piece 12 during use will affect the appearance of the electronic device and damage the user's experience.

[0099] Generally, in order to reduce the risk of poor contact between the male connector and the female connector due to the skew of the first connecting piece, the volume of the female connector 2 is usually increased.

[0100] Figure 7 A partial cross-sectional view of a stylus is shown when the female connector is increased. As Figure 7 shown, the stylus also includes a plurality of signal terminals, for example, the stylus 5 includes TX1 signal, TX2 signal and GND signal, wherein the TX1 signal terminal is used to transmit the signal required to be transmitted by the connector assembly, and is used to obtain the input information of the user. The TX2 signal terminal is used to transmit other signals. The GND signal terminal is used for grounding. As Figure 7 shown, the TX1 signal terminal, the GND signal terminal and the TX2 signal terminal are sequentially arranged in the pen barrel from inside to outside. The connection end of the TX1 signal is the male connector 1, and the pen tip is the female connector 2. When the volume of the female connector 2 is increased, it is easy to cause the female connector 2 to mis-touch the terminals of the TX2 signal and the GND signal around the male connector 1, causing short circuit or signal transmission failure.

[0101] The embodiment of the present application changes the structure of the connector assembly to reduce the risk of poor contact caused by misalignment between the male connector and the female connector during use of the electronic device.

[0102] Figure 8 A structural schematic diagram of the connector assembly in a specific embodiment is shown. As Figure 8 shown, the present application provides a connector assembly, which includes a male connector 1 and a female connector 2. The male connector 1 can serve as the male end of the connector assembly, and the female connector 2 can serve as the female end of the connector assembly. When the male connector 1 and the female connector 2 are in contact, they are electrically connected.

[0103] The male connector 1 comprises a first shell 11, a first connecting piece 12 and a first elastic piece 13. The first shell 11 has a first accommodating cavity 111, and the first elastic piece 13 is located in the first accommodating cavity 111. One end of the first elastic piece 13 is connected with the first connecting piece 12, and the other end is connected with the inner wall of the first shell 11. The connection mode can be fixed connection or detachable connection, and the connection mode includes but is not limited to abutment, clamping, bonding and the like. The first connecting piece 12 comprises a first connecting part 121 and a first limiting part 122 connected with each other. The first shell 11 has a through hole in communication with the first accommodating cavity 111, and the first connecting part 121 can extend out of the first accommodating cavity 111 through the through hole. The first limiting part 122 is arranged along the circumference of the first connecting part 121, and the first limiting part 122 protrudes relative to the first connecting part 121 along the radial direction of the first connecting piece 12, and the first limiting part 122 is located in the first accommodating cavity 111. The first shell 11 comprises a second limiting part 112, which is arranged along the circumference of the first accommodating cavity 111. During the movement of the first connecting piece 12 relative to the first shell 11, the second limiting part 112 can abut against the first limiting part 122, so as to limit the first connecting piece 12 from being separated from the first accommodating cavity 111.

[0104] Correspondingly, as shown in Figure 8 , the side of the female connector 2 for connecting with the first connecting piece 12 of the male connector 1 is provided with a guide part 221. The surface of the guide part 221 for contacting with the first connecting piece 12 of the male connector 1 can be an arc surface, an inclined surface, a curved surface or the like. When the male connector 1 and the female connector 2 approach each other, the first connecting part 121 abuts against the guide part 221 to electrically connect the male connector 1 and the female connector 2.

[0105] Please refer to Figure 9 , Figure 9 , which shows the abutment between the female connector 2 and the first connecting part 121 of the male connector 1. In this embodiment, the axes of the male connector 1 and the female connector 2 do not deviate, i.e. the male connector 1 and the female connector 2 are not misaligned. During the abutment between the first connecting part 121 of the first connecting piece 12 and the guide part 221, the guide part 221 can apply a first external force to the first connecting part 121. The direction of the first external force is along the axial direction of the first connecting piece 12, so as to move the first connecting piece 12 relative to the first shell 11 along the axial direction of the first connecting piece 12.

[0106] Please refer to Figure 10 , Figure 10The schematic view shows the abutment of the female connector 2 and the first connecting part 121 of the male connector 1, at this time, the axis of the male connector 1 deviates from the axis of the female connector 2, that is, the male connector 1 is misaligned with the female connector 2. During the abutment of the first connecting part 121 of the first connecting member 12 and the guide part 221, the guide part 221 can exert a second external force on the first connecting part 121, the direction of the second external force is inclined relative to the direction of the axis of the first connecting member 12, so that the first connecting member 12 has a tendency to move obliquely relative to the direction of the axis of the first housing 11 under the action of the second external force.

[0107] At least one of the first limiting part and the second limiting part is provided with a guide surface. For example, Figure 10 In the embodiment shown, the first limiting part 122 is provided with a first guide surface 141, and the second limiting part 112 is provided with a second guide surface 142. During the movement of the first connecting member 12 relative to the first housing 11, the first guide surface 141 and the second guide surface 142 can be fitted, so that the first connecting member 12 can swing relative to the first housing 11. The first guide surface 141 and the second guide surface 142 are arc surfaces, and can also be spherical surfaces. In the radial direction of the first connecting member 12, there is a first gap 15 between the first connecting part 121 of the first connecting member 12 and the through hole of the first housing 11. The first guide surface 141 and the second guide surface 142 allow the first connecting member 12 to swing relative to the first housing 11, and the first gap 15 prevents the first housing 11 from restricting the swing of the first connecting member 12 relative to the first housing 11.

[0108] In a possible implementation, the size of the first gap is 0.2mm to 1mm. For example, the size of the first gap can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm.

[0109] Unlike the error gap caused by insufficient fitting accuracy, the scheme provided by the embodiment of the application can provide space for the swing of the first connecting member by setting the first gap, reduce the possibility of contact between the first connecting member and the second limiting part during the swing, and thus reduce the possibility of interference between the first connecting member and the first housing during the swing, which is conducive to improving the stability of the movement of the first connecting member and reducing the possibility of deformation of the first connecting member under pressure.

[0110] Please refer to Figure 11 , Figure 11 The schematic view shows the abutment of the female connector 2 and the first connecting part 121 of the male connector 1, at this time, the axis of the male connector 1 deviates from the axis of the female connector 2, that is, the male connector 1 is misaligned with the female connector 2. During the abutment of the first connecting part 121 of the first connecting member 12 and the guide part 221, the guide part 221 can exert a second external force on the first connecting part 121, the direction of the second external force is inclined relative to the direction of the axis of the first connecting member 12, so that the first connecting member 12 has a tendency to move obliquely relative to the direction of the axis of the first housing 11 under the action of the second external force. Figure 11At the position shown, the axis of the first connecting member 12 and the axis of the first housing 11 have an included angle, i.e. the axis of the first connecting member 12 is not parallel to the axis of the first housing 11.

[0111] Please refer to Figure 12 , Figure 12 A schematic view showing that the female connector 2 and the male connector 1 continue to approach each other is shown. Under the action of the second external force, the first connecting member 12 continues to move away from the female connector 2, compresses the first elastic member 13, and makes the first guide surface 141 and the second guide surface 142 disengage from each other, and the first connecting member 12 continues to swing towards the center of the female connector 2, thereby facilitating the stability of the connection between the first connecting member 12 and the female connector 2, and more in line with the actual use requirements. In addition, under the action of the second external force, the first connecting member 12 will not be bent, so that it can improve the stability of the connection between the male connector 1 and the female connector 2, and also reduce the possibility of deformation of the first connecting member 12 under pressure, thereby reducing the possibility of damage to the first connecting member 12.

[0112] Please continue to refer to Figure 13 , Figure 13 A schematic view showing that the male connector 1 and the female connector 2 return to the initial state is shown. When the male connector 1 and the female connector 2 are disconnected, under the action of the restoring force of the first elastic member 13, the first connecting member 12 swings in the opposite direction and gradually resets.

[0113] Please continue to refer to Figure 14 , Figure 14The schematic view shows that the axis of the first connecting piece 12 has an angle with the axis of the first shell 11 in the assembling process, that is, the first connecting piece 12 is misaligned. In the process of the male connector 1 and the female connector 2 approaching each other, the first connecting part 121 of the first connecting piece 12 abuts against the guide part 221, and the guide part 221 applies a second external force to the first connecting part 121. Due to the inclination of the axis of the first connecting piece 12 relative to the axis of the first shell 11, the direction of the second external force applied by the guide part 221 to the first connecting piece 12 is inclined relative to the direction of the axis of the first shell 11, so that the first connecting piece 12 has a tendency to move obliquely relative to the axial direction of the first shell 11 under the action of the second external force. At the same time, the first connecting piece 12 and the first shell 11 abut against the first guide surface 141 and the second guide surface 142, so that the first connecting piece 12 swings relative to the first shell 11, and the first gap 15 provides space for the swing of the first connecting piece 12. When the female connector 2 and the male connector 1 continue to approach each other, the first connecting part 121 moves towards the inside of the first accommodating cavity 111 in the process of the swing of the first connecting piece 12. In addition, by arranging the first gap 15 between the first connecting piece 12 and the second limiting part 112, the possibility of interference between the first connecting part 121 and the second limiting part 112 when the first connecting piece 12 swings can be reduced, thereby facilitating the swing of the first connecting piece to the central position of the guide part 221, so as to improve the connection stability between the male connector 1 and the female connector 2.

[0114] Please continue to refer to Figure 15 , Figure 15 The schematic view shows the structure of the male connector 1 and the female connector 2 when they continue to approach each other. As shown in Figure 15 , the male connector 1 and the female connector 2 continue to approach each other to make the first connecting piece 12 swing, and the first connecting piece 12 can swing to a position where the axis of the first connecting piece 12 coincides with the axis of the first shell 11, that is, the misaligned first connecting piece 12 can be corrected, so that the first connecting piece 12 moves towards the central direction of the female connector 2 by swinging while moving along the axial direction of the first shell 11, which is conducive to improving the connection stability between the first connecting piece 12 and the female connector 2 and more meets the actual use requirements.

[0115] In addition, the above scheme does not need to increase the volume of the female connector to improve the connection stability between the male connector and the female connector, thereby facilitating the reduction of the overall volume of the connector assembly. When the connector assembly includes a plurality of male connectors and female connectors, the possibility of accidental touch between the male connectors and the female connectors can be reduced, and the possibility of deformation of the structural parts between adjacent female connectors can be reduced.

[0116] As Figure 15As shown, in the embodiment, the first limiting portion 122 is provided with a first guide surface 141, the second limiting portion 112 is provided with a second guide surface 142, the contact between the first limiting portion 122 and the second limiting portion 112 is surface contact, the contact area between the two is relatively large, which is beneficial to improve the stability of the first connecting piece 12 when swinging relative to the first shell 11, thereby improving the connection stability of the male connector 1 and the female connector 2.

[0117] In addition, in a possible implementation, the first guide surface and the second guide surface can be spherical surfaces, which can be used to realize that the first connecting piece can swing in different directions. When the male connector and the female connector are misaligned in different directions or the first connecting piece is inclined in different directions, the first connecting piece can swing to the center position of the second connecting end, thereby improving the stability of the connection between the male connector and the female connector.

[0118] The spherical position of the first guide surface can coincide with the spherical center position of the second guide surface. Please continue to refer to Figure 16 , Figure 16 As shown in the structure diagram of the guide surface 14 provided on the second limiting portion 112. In a possible implementation, the first limiting portion 122 is provided with the guide surface 14, the second limiting portion 112 is not provided with the guide surface, and the outer edge of the second limiting portion 112 is used to abut against the guide surface 14. The cross section of the second limiting portion 112 can be rectangular, and the corner position can be used as the outer edge of the second limiting portion 112, so that the contact between the second limiting portion 112 and the guide surface 14 is approximately linear contact, thereby reducing the contact area between the first limiting portion 122 and the second limiting portion 112, thereby facilitating the relative movement of the first limiting portion 122 and the second limiting portion 112 along the guide surface 14. When the male connector 1 and the female connector 2 are misaligned or the installation of the first connecting piece 12 deviates, the first connecting piece 12 can swing, so that the first connecting piece 12 moves to the center position of the female connector 2, and the deviation is corrected, thereby improving the stability of the connection between the male connector 1 and the female connector 2.

[0119] As Figure 17 shown, Figure 17The structure schematic view of the guide surface 14 arranged at the first limiting part 122 is shown, in a possible implementation, the second limiting part 112 is arranged with the guide surface 14, the first limiting part 122 is not arranged with the guide part, and the outer edge of the first limiting part 122 is used to abut against the guide surface 14. The cross section of the first limiting part 122 can be rectangular, and the corner position of the rectangle can be used as the outer edge of the first limiting part 122, so that the contact between the first limiting part 122 and the guide surface 14 is approximately linear contact, thereby reducing the contact area between the first limiting part 122 and the second limiting part 112, facilitating the relative movement of the first limiting part 122 and the second limiting part 112 along the guide surface 14, so that when the male connector 1 and the female connector 2 are misaligned or the installation of the first connecting piece 12 deviates, the first connecting piece 12 can swing, thereby making the first connecting piece 12 close to the center position of the female connector 2, correcting the deviation, and improving the stability of the connection between the male connector 1 and the female connector 2.

[0120] As shown in Figure 17 , in a possible implementation, the first elastic member 13 can be a spring, foam or other elastic component. When the connector assembly is connected, the male connector 1 and the female connector 2 are close to each other, the first connecting piece 12 contacts the female connector 2, and as the male connector 1 and the female connector 2 gradually approach, the first connecting piece 12 moves relative to the first housing 11, and the first elastic member 13 linearly deforms, usually, the first elastic member 13 is compressed. The restoring force generated by the deformation of the first elastic member 13 can act on the first connecting piece 12, so that the first connecting piece 12 has a tendency to move towards the female connector 2. Through such design, the stability of the connection between the first connecting piece 12 and the female connector 2 can be improved, thereby improving the stability of the electrical connection of the connector assembly.

[0121] As shown in Figure 17 , the first elastic member 13 is sleeved with the first connecting piece 12, which can increase the contact area between the first elastic member 13 and the first connecting piece 12, make the movement of the first connecting piece 12 more stable, and reduce the possibility of the first elastic member 13 separating from the first connecting piece 12. At the same time, when the first connecting piece 12 moves relative to the first housing 11 and the first elastic member 13 deforms elastically, the sleeving mode can guide the first connecting piece 12 and the first elastic member 13, thereby further improving the stability of the secondary movement and deformation, and more meeting the actual use requirements.

[0122] Specifically, as shown in Figure 17As shown, the first connecting piece 12 includes a second connecting portion 123, the first connecting portion 121 and the second connecting portion 123 are located on both sides of the first limiting portion 122, and the second connecting portion 123 is located in the first accommodating cavity 111. The first elastic piece 13 is sleeved outside the second connecting portion 123 along the axial direction of the male connector 1, and can abut against the first limiting portion 122, which can increase the contact area of the first elastic piece 13 and the first connecting piece 12, thereby facilitating the stability of the connection between the first elastic piece 13 and the first connecting piece 12.

[0123] Please continue to refer to Figure 18 , Figure 18 As shown, the first elastic piece 13 is sleeved inside the first connecting piece 12. The first connecting piece 12 includes a second connecting portion 123, the first connecting portion 121 and the second connecting portion 123 are located on both sides of the first limiting portion 122, and the second connecting portion 123 is located in the first accommodating cavity 111. The second connecting portion 123 has a cavity 123a, and the opening of the cavity 123a faces the side where the first elastic piece 13 is located. Part of the first elastic piece 13 is located in the cavity 123a, that is, the second connecting portion 123 is sleeved outside the first elastic piece 13.

[0124] Through such a design, the contact area of the first connecting piece and the first elastic piece can be further increased, and the possibility of the first elastic piece being separated from the first connecting piece can be reduced. The first elastic piece can abut against the bottom wall of the cavity along the axial direction of the male connector. At the same time, during the movement of the first connecting piece, the deformation of the first elastic piece can be guided, thereby improving the stability of the deformation and movement of the first elastic piece, and further facilitating the stability of the electrical connection between the male connector and the female connector, and reducing the possibility of poor contact.

[0125] As Figure 18 shown, in a possible implementation, along the radial direction of the first connecting piece 12, the second connecting portion 123 and the inner wall of the first accommodating cavity 111 have a second gap 16, and the size of the second gap 16 is 0.2 millimeters to 1.5 millimeters. The size of the second gap 16 can be 0.2 millimeters, 0.4 millimeters, 0.6 millimeters, 0.8 millimeters, 1.0 millimeter, 1.2 millimeters, 1.4 millimeters, 1.5 millimeters, etc.

[0126] By providing a second gap between the second connecting portion and the inner wall of the first accommodating cavity, when the first connecting piece swings, the first connecting piece can be inclined relative to the axial direction of the male connector, so as to utilize the swing of the first connecting piece to move the first connecting piece to the central position of the female connector, thereby improving the stability of the electrical connection between the male connector and the female connector.

[0127] As Figure 18As shown, in one possible embodiment, one of the first connecting portion 121 and the guide portion 221 is provided with a protrusion 121a and the other with a recess 221a. When the male connector 1 and the female connector 2 are mated, at least a portion of the protrusion 121a can extend into the recess 221a.

[0128] This design improves the relative positional accuracy of the male and female connectors when they mate, thereby enhancing the stability of their contact and reducing the likelihood of poor contact.

[0129] like Figure 18 As shown, in one possible implementation, the first connecting portion 121 is provided with a protrusion 121a, and the recessed portion 221a is located in the guide portion 221 and recessed into the guide portion 221. The end of the first connecting member 12 away from the first receiving cavity 111 can serve as the protrusion 121a. The end of the first connecting member 12 away from the first receiving cavity 111 can be arc-shaped. The recessed portion 221a can be an arc-shaped recess. Specifically, the surface of the recessed portion 221a that contacts the protrusion 121a is a spherical surface.

[0130] With this design, when the male and female connectors are misaligned, the first connector contacts the inner wall of the recess. At this time, the force direction of the first connector forms an angle with the axial direction of the male connector, allowing the first connector to move relative to the first housing along the guide surface, thus causing the first connector to swing. Simultaneously, as the male and female connectors approach each other, the first connector moves along the inner wall of the recess towards the center of the recess, so that the male connector can contact the center of the female connector, thereby improving the electrical...

[0131] The spherical surface of the protrusion and the recessed part in contact with each other can cause the first connector to receive forces in different directions when there are errors in different directions during the mating of the male and female connectors. This causes the first connector to swing in different directions, and the first connector moves closer to the center of the second connector through the swing, which helps to improve the stability of the connection between the male and female connectors.

[0132] like Figure 19As shown in a possible implementation, the shapes of the protruding part 121a and the recessed part 221a are correspondingly arranged, and the cross-sectional shape of the protruding part 121a and the recessed part 221a can be arc-shaped, triangular, trapezoidal, or the like. The inner surface of the recessed part 221a and the outer surface of the protruding part 121a can have an arc surface, an inclined surface, or the like, so as to guide when the male connector 1 and the female connector 2 are in contact, thereby improving the fitting accuracy of the male connector 1 and the female connector 2, and more meeting the actual use requirements.

[0133] The scheme provided in the embodiment of the application can make the first connecting piece swing by arranging a gap between the first connecting piece and the first shell and arranging an arc-shaped guide surface between the first limiting part and the second limiting part. When the male connector and the female connector are connected, the first connecting piece swings to the center position of the female connector, improves the reliability of the electrical connection between the male connector and the female connector, and reduces the possibility of the first connecting piece being deformed under pressure and the possibility of the first connecting piece being damaged during the connection process.

[0134] As shown in the embodiment, Figure 20 In a possible implementation, the first connecting piece 12 and the second limiting part 112 can be filled with a second elastic piece 17, and the second elastic piece 17 can be used to fill the first gap. The second elastic piece 17 can be conductive foam or other elastic conductive materials. The first connecting piece 12 abuts against the first shell 11 through the second elastic piece 17, and the second elastic piece 17 can limit the first connecting piece 12.

[0135] During the assembly of the male connector, when the first connecting piece is inclined, the first connecting piece can extrude the second elastic piece, and the second elastic piece can be deformed. The restoring force generated by the deformation of the second elastic piece can act on the first connecting piece, so that the first connecting piece moves in the opposite direction of the inclination, so that the first connecting piece is righted, thereby improving the relative position accuracy of the first connecting piece and the first shell, thereby reducing the possibility of the first connecting piece being inclined during installation, or reducing the degree of inclination of the axis of the first connecting piece relative to the axis of the first shell.

[0136] During the process that the male connector and the female connector approach each other, the second elastic piece can provide buffering when the first connecting piece swings. The first connecting piece can not directly contact the first shell, thereby reducing the friction between the first connecting piece and the first shell, and further reducing the possibility of the first connecting piece being damaged, which is conducive to prolonging the service life of the first connecting piece and the connector assembly.

[0137] As shown in the embodiment, Figure 21As shown, in a possible implementation, the female connector 2 can include a second connecting piece 22, a second housing 21, and a third elastic piece 23. The second housing 21 has a second accommodating cavity 211, a guide portion 221 is arranged on the second connecting piece 22, and the second connecting piece 22 and the third elastic piece 23 are connected and installed in the second accommodating cavity 211. The second connecting piece 22 is configured to cooperate with the first connecting piece 12 to electrically connect the male connector 1 and the female connector 2. The second connecting piece 22 is movable relative to the second housing 21, and the third elastic piece 23 is elastically deformed when the second connecting piece 22 moves relative to the second housing 21.

[0138] When the male connector and the female connector are connected, as the male connector and the female connector approach each other, the second connecting piece is driven to move relative to the second housing, and the third elastic piece is deformed. The restoring force generated by the deformation of the third elastic piece can act on the second connecting piece, so that the second connecting piece has a movement trend in the direction of approaching the male connector, thereby facilitating the stability of the electrical connection between the male connector and the female connector, and more meeting the actual use requirements.

[0139] As shown, Figure 21 As shown, Figure 21 FIG. 2 is a schematic view of the female connector 2. In a possible implementation, the second connecting piece 22 includes a third limiting portion 222 arranged along the circumference of the guide portion 221. The second housing 21 is provided with a fourth limiting portion 212 arranged on the inner wall of the second accommodating cavity 211 and along the circumference of the second accommodating cavity 211. The third limiting portion 222 and the fourth limiting portion 212 abut, and are configured to limit the second connecting piece 22 from being separated from the second accommodating cavity 211. At least one of the third limiting portion 222 and the fourth limiting portion 212 is provided with an arc-shaped surface, and the third limiting portion 222 and the fourth limiting portion 212 contact through the arc-shaped surface. Specifically, the arc-shaped surface can be a spherical surface. Figure 21As shown, in one possible implementation, the third limiting portion 222 is provided with a first arcuate surface 212a, and the fourth limiting portion 212 is provided with a second arcuate surface 222a. The structures of the third limiting portion 222 and the fourth limiting portion 212 can be approximately the same as those of the first limiting portion 122 and the second limiting portion 112, that is, at least a portion of the first arcuate surface 212a and / or at least a portion of the second arcuate surface 222a is an arcuate surface. The third limiting portion 222 and the fourth limiting portion 212 can move relative to each other along the first arcuate surface 212a and the second arcuate surface 222a. Along the radial direction of the female connector 2, the guide portion 221 and the fourth limiting portion 212 have a third gap 24, so that the second connector 22 can swing relative to the second housing 21. By providing arc-shaped surfaces in both the third limiting part 222 and the fourth limiting part 212, the contact area of ​​the third limiting part 222 and the fourth limiting part 212 can be increased, which is beneficial to improving the stability of the relative movement of the third limiting part 222 and the fourth limiting part 212. The third gap 24 is used to increase the space for the second connector 22 to swing, reducing the possibility of interference between the second connector 22 and the second housing 21 during the swinging process. During the connection of the male connector 1 and the female connector 2, when the male connector 1 and the female connector 2 are misaligned, as the male connector 1 and the female connector 2 approach each other, since the force direction of the first connector 12 and the force direction of the second connector 22 are not on the same straight line, both the first connector 12 and the second connector 22 can swing to adjust the relative position of the first connector 12 and the second connector 22. This is beneficial to improving the relative positional accuracy of the first connector 12 and the second connector 22, improving the stability of the electrical connection between the male connector 1 and the female connector 2, and better meeting the actual use requirements.

[0140] Please refer to Figure 22 , Figure 22 This is a schematic diagram of the connector assembly provided in the embodiments of this application applied to a stylus. Figure 8 to Figure 21 The connector assembly shown can be used in a stylus, specifically, Figure 22 for Figure 9 The diagram shows a connector assembly used in a stylus 5. In the illustrated scheme, the female connector 2 is located on the pen tip structure 51, and the male connector is located on the pen barrel 52. During use, by driving the pen tip structure 52 to move relative to the pen barrel 52 along the axis of the stylus, the female connector 2 and the male connector 1 come into contact, achieving an electrical connection to transmit user input signals.

[0141] When the connector assembly is applied to the stylus, the end of the connector assembly away from the nib structure can also be provided with a first connecting piece, that is, along the axial direction of the connector assembly, the opposite ends of the male connector are respectively provided with a first connecting piece, and the two first connecting pieces are respectively used for electrical connection with the female connector provided on the nib structure and the female connector provided on the pen barrel. The opposite ends of the first elastic piece are respectively connected with the two first connecting pieces, when one of the first elastic pieces moves along the axial direction of the connector assembly and shrinks into the first housing, the first elastic piece can be squeezed, so that the first elastic piece is compressed. Since the opposite ends of the first elastic piece are respectively connected with different first connecting pieces, the restoring force generated by the first elastic piece can simultaneously act on the two first connecting pieces, so that the two first connecting pieces have opposite movement trends, that is, the two first connecting pieces respectively have the trend of moving towards the direction close to the corresponding female connector, thereby facilitating to improve the stability of the connection between each first connecting piece and the corresponding female connector.

[0142] The above describes the structure of the connector assembly including one male connector and one female connector. In other embodiments, the connector assembly can also include multiple male connectors and multiple female connectors.

[0143] Please refer to Figure 23 , Figure 23 The schematic diagram showing that the connector assembly includes at least two male connectors 1 and at least two female connectors 2. The connector assembly includes at least two male connectors 1 and at least two female connectors 2, and the number of male connectors 1 and female connectors 2 is the same, and the number of male connectors 1 and female connectors 2 can be two, three, four, etc. respectively. In use, each male connector 1 and the corresponding female connector 2 cooperate to achieve electrical connection. By providing multiple male connectors 1 and female connectors 2, the stability of the connector assembly and the transmission efficiency of the signal can be improved, which is more in line with the actual use requirements.

[0144] As Figure 24 shown, Figure 24 is a structural schematic diagram when the electronic device is a tablet computer 6 and a keyboard 7. When the tablet computer is large in size, its working state can be similar to that of a personal computer (PC). The user of the tablet computer generally has the need for typing input, so the tablet products of various manufacturers will launch the corresponding keyboard (such as keyboard) accessories of the tablet to support the functions of keys, touch pads, NFC (Near Field Communication), etc. The keyboard corresponding to the tablet computer can use pogo pin (pogo pin, or spring pin) to realize data transmission. Specifically, the tablet computer and the keyboard can be connected through Figure 23The shown connector assembly enables data transmission.

[0145] As Figure 23 shown, the connector assembly can further include a first body part 3 and a second body part 4, the male connectors 1 are arranged on the first body part 3, and the female connectors 2 are arranged on the second body part 4. That is, the plurality of male connectors 1 are integrated on the first body part 3, and the plurality of female connectors 2 are integrated on the second body part 4. The first body part 3 and the second body part 4 can be respectively used for integrating the male connectors 1 and the female connectors 2, so that the male connectors 1 and the female connectors 2 are modularized respectively, facilitating installation in the tablet computer and the keyboard. The first body part 3 and the second body part 4 can be separate housings, or structural members of the housings of the tablet computer and the keyboard.

[0146] As Figure 24 shown, the male connectors 1 and the female connectors 2 of the connector assembly are arranged on one of the tablet computer 6 and the keyboard 7. For example, when the male connectors 1 are arranged on the tablet computer 6, the female connectors 2 are arranged on the keyboard 7; when the male connectors 1 are arranged on the keyboard 7, the female connectors 2 are arranged on the tablet computer 6. Hereinafter, the male connectors 1 are arranged on the tablet computer 6, and the female connectors 2 are arranged on the keyboard 7 as an example. Figure 24 The arrangement positions of the male connectors 1 and the female connectors 2 are shown in the dotted box in FIG. 1.

[0147] Specifically, the male connectors are arranged at the bottom of the tablet computer, and the female connectors are arranged on the upper surface of the keyboard and staggered with the keys of the keyboard.

[0148] Figure 25 For Figure 24 example, the connector assembly can include three male connectors 1 and three female connectors 2. Figure 25 As

[0149] Similarly to the foregoing stylus, as Figure 25 shown, during assembly, the connector assembly connecting the tablet computer 6 and the keyboard 7 also has the problem that some components are misaligned or skewed. For example, there is a risk that the axis of the male connector 1 does not coincide with the axis of the female connector 2, that is, there is a risk that the male connector 1 and the female connector 2 are misaligned, or there is a risk that the axis of the first connecting piece of the male connector 1 is inclined relative to the axis of the first housing, that is, there is a risk that the first connecting piece is skewed.

[0150] As Figure 25In the shown embodiment, the male connector 1 and the female connector 2 are misaligned as an example for description. When the male connector 1 and the female connector 2 are misaligned, the first connecting piece of the male connector 1 deviates from the preset position, and thus the first connecting piece may not contact the edge of the female connector 2 or may not contact the female connector 2, which easily leads to poor contact, and thus the connection reliability of the male connector and the female connector is poor, and the data transmission between the tablet computer and the keyboard is affected.

[0151] As shown in Figure 26 To reduce the risk of poor contact caused by misalignment of the male connector 1 and the female connector 2, the size of the female connector 2 can be increased to improve the connection stability. However, increasing the size of the female connector 2 will reduce the spacing between adjacent female connectors 2, and the male connector 1 and the female connector 2 are easily misaligned and miscontacted during use, which leads to short circuit and other problems. At the same time, the spacing between adjacent female connectors 2 is reduced, and the size of the structural member between adjacent female connectors 2 is also reduced, which leads to a decrease in the structural strength of the region and easy deformation and even damage under stress.

[0152] As shown in Figure 27 The connector assembly provided by the embodiment of the present application is applied to the tablet computer and the keyboard as shown in Figure 27 In a possible implementation, one of the tablet computer and the keyboard is provided with a limiting protrusion 31, and the other is provided with a limiting recess 41. At least part of the limiting protrusion 31 can extend into the limiting recess 41. When the tablet computer and the keyboard are matched, the limiting protrusion 31 and the limiting recess 41 are matched, thereby limiting the tablet computer and the keyboard, and thus the relative position accuracy of the male connector 1 and the female connector 2 located on the tablet computer and the keyboard can be improved, and the stability of the electrical connection of the male connector 1 and the female connector 2 can be improved, which is more in line with the actual use requirements.

[0153] As shown in Figure 27 In a possible implementation, one of the tablet computer and the keyboard is provided with a magnetic member 32, and the other is provided with a matching member 42. The matching member 42 can be a component with magnetism or a component that can be attracted by the magnetic member 32. The magnetic member 32 and the matching member 42 can be magnetically attracted and connected. When the connector assembly is used, the tablet computer and the keyboard can be positioned by the magnetic attraction between the magnetic member 32 and the matching member 42. When the tablet computer and the keyboard are misaligned, the magnetic attraction between the magnetic member 32 and the matching member 42 can be used for correction, and thus the relative position accuracy of the male connector 1 and the female connector 2 can be improved, and the stability of the electrical connection of the male connector 1 and the female connector 2 can be improved.

[0154] Figure 28 ToFigure 27 A partial enlarged view of the middle I part. As shown in Figure 28 The first connecting piece 12 of the male connector 1 is provided with a first guide surface 141, and the first shell 11 is provided with a second guide surface 142. When the male connector 1 and the female connector 2 are misaligned or the first connecting piece 12 is misaligned, the first connecting piece 12 can move along the second guide surface 142 relative to the first shell 11 through the first guide surface 141 during the mating of the male connector 1 and the female connector 2, so as to swing to make the first connecting piece 12 swing towards the center of the female connector 2. The first gap 15 is used to provide a space for swinging, so as to reduce the possibility of interference between the first connecting piece 12 and the first shell 11 during the swinging. The first connecting piece 12 can also be corrected during the swinging, so as to adjust the relative positions of the first connecting piece 12 and the female connector 2 when the male connector 1 and the female connector 2 are misaligned or the first connecting piece 12 is misaligned, so as to improve the stability of the connection of the male connector 1 and the female connector 2. When the connector assembly is applied to the connection between the tablet computer and the keyboard, the stability of the connection between the tablet computer and the keyboard can be improved, and it is more in line with the actual use requirements.

[0155] Meanwhile, as shown in Figure 27 On the basis of the swing of the first connecting piece 12, the limiting protrusion 31 and the magnetic piece 32 are arranged on the tablet computer, and the limiting recess 41 and the cooperating piece 42 are arranged on the keyboard. Correspondingly, the magnetic piece 32 and the cooperating piece 42 can be magnetically attached and connected, and the limiting protrusion 31 and the limiting recess 41 can be concave-convex matched and limited. The two can be pre-positioned during the connection of the male connector 1 and the female connector 2, and can also play a role in correcting the deviation to a certain extent. Meanwhile, on the basis of the magnetic attachment and the concave-convex matching and limiting, the deviation is corrected through the swing of the first connecting piece, which is conducive to further improving the stability of the connection between the male connector 1 and the female connector 2.

[0156] As shown in Figure 27 During the electrical connection of the male connector 1 and the female connector 2, the limiting protrusion 31, the limiting recess 41, the magnetic piece 32 and the cooperating piece 42 can be pre-positioned, so as to play a role in preventing mistakes, so as to improve the relative position accuracy of the male connector 1 and the female connector 2, and thus be conducive to improving the stability of the electrical connection of the connector assembly. Meanwhile, the connection position of the male connector 1 and the female connector 2 is calibrated by the swing of the first connecting piece 12, and the magnetic attraction is combined with the swing of the first connecting piece 12, which is compared with the scheme of limiting the male connector and the female connector 2 by the magnet, Figure 27In the provided scheme, the male connector 1 and the female connector 2 are pre-positioned by magnetic adsorption connection, which also plays a role of preventing errors, reduces the relative position error between the tablet computer and the keyboard, and further adjusts the relative position between the first connecting piece and the guide part through swinging of the first connecting piece. Since the first connecting piece can adjust its position through swinging, the installation precision requirement and the matching precision requirement of the magnetic piece 32 and the matching piece 42 can be reduced. After the male connector 1 and the female connector 2 are pre-positioned by the magnetic piece 32 and the matching piece 42, swinging of the first connecting piece is beneficial to further improve the connection precision of the male connector and the female connector, thereby improving the connection stability.

[0157] In summary, the scheme provided by the embodiments of the present application can adjust the angle and position of the first connecting piece by swinging of the first connecting piece, perform self-adaptive deviation correction, so as to improve the stability of the connection between the male connector and the female connector without increasing the volume of the female connector. Meanwhile, by arranging the first recess part on the female connector, the surface area of the female connector can be increased without increasing the volume of the female connector, thereby facilitating the electrical connection between the male connector and the female connector. By sleeving the first elastic piece on the first connecting piece, the stability of the connection between the first elastic piece and the first connecting piece can be improved, thereby improving the stability of the movement of the first connecting piece relative to the first shell.

[0158] When the first main body part and the second main body part are separate shells for integrating the male connector and the female connector, the magnetic piece, the matching piece, the limiting protrusion and the limiting recess can be arranged on the first main body part or the second main body part according to actual use requirements.

[0159] In a possible implementation, the connector assembly provided by the embodiments of the present application can also be applied to electronic devices such as mobile phones and notebook computers.
