Description

Connector assembly, male connector and electronic device

[0001] The present application claims priority to the Chinese patent application No. 202410740912.6, filed on June 7, 2024, and entitled "Connector assembly, male connector and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the technical field of electrical connectors, and in particular to a connector assembly, a male connector and an electronic device. BACKGROUND

[0003] 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

[0004] The present application provides a connector assembly, a male connector and an electronic device to improve the stability of the connection between the male connector and the female connector.

[0005] The first aspect of the present application provides a connector assembly, which comprises:

[0006] at least one female connector, the female connector comprising a guide portion;

[0007] 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;

[0008] 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;

[0009] The first shell comprises a second limiting portion for abutting with the first limiting portion, at least one of the first limiting portion and the second limiting portion is provided with an arc-shaped guide surface, the first limiting portion and the second limiting portion abut through the guide surface, and the first connecting piece and the second limiting portion have a first gap in the radial direction of the first connecting piece.

[0010] By arranging the arc-shaped guide surface, the first connecting piece can move along the guide surface relative to the first shell when the axis of the male connector does not coincide with the axis of the female connector or when the first connecting piece is misaligned, so that the stress position of the first connecting piece changes, and the first connecting piece can also move along the guide surface when moving in the axial direction of the first shell. By moving along the guide surface, the first connecting piece can swing, so that the first connecting piece swings towards the center of the female connector. The first gap is used to provide space for the swing of the first connecting piece, so as to reduce the possibility of interference between the first connecting piece and the first shell during the swing. By arranging the arc-shaped guide surface and the first gap, the first connecting piece can swing, and the swing of the first connecting piece can be used for correction, so as to improve the stability of the connection between the male connector and the female connector, and reduce the possibility of poor contact of the connector assembly.

[0011] 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 with the second limiting portion, or

[0012] 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 with the first limiting portion.

[0013] The contact area between the first limiting portion and the second limiting portion is reduced, so as to facilitate the relative movement of the first limiting portion and the second limiting portion along the guide surface, so that when the male connector and the female connector are misaligned or the installation of the first connecting piece deviates, the first connecting piece can swing, so as to make the first connecting piece close to the center of the female connector, correct the deviation, and improve the stability of the connection between the male connector and the female connector.

[0014] In a possible implementation, the first limiting portion is provided with a first guide surface, and the second limiting portion is provided with a second guide surface, and the first guide surface and the second guide surface abut.

[0015] The contact between the first limiting portion and the second limiting portion is surface contact, and the contact area between them is relatively large, which is conducive to improving the stability of the swing of the first connecting piece relative to the first shell, and thus conducive to improving the connection stability of the male connector and the female connector.

[0016] In a possible implementation, the guide surface is a spherical surface.

[0017] The first guide surface and the second guide surface can be spherical surfaces, which can be used to enable the first connecting member to swing in different directions. When the male connector and the female connector are misaligned in different directions or the first connecting member is inclined in different directions, the first connecting member 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.

[0018] 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, that is, the guide surface can be equivalent to a part of a complete spherical surface.

[0019] 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.

[0020] 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 member by arranging the first gap, thereby reducing the possibility of contact between the first connecting member and the second limiting portion during the swing, reducing the possibility of interference between the first connecting member and the first housing during the swing, facilitating the stability of the movement of the first connecting member, and reducing the possibility of deformation of the first connecting member under pressure.

[0021] 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.

[0022] 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.

[0023] In a possible implementation, the recessed portion is arranged at the guide portion, and the protruding portion is arranged at the first connecting portion.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] In a possible implementation, the male connector comprises a second elastic piece, and the second elastic piece fills the first gap.

[0029] 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 straightened, 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 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 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.

[0030] In a possible implementation, the first connecting piece further comprises a second connecting part connected with the first limiting part, and the first connecting part and the second connecting part are located on two sides of the first limiting part.

[0031] The first elastic piece is sleeved inside the second connecting part, or the first elastic piece is sleeved outside the second connecting part.

[0032] Through the 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, the deformation of the first elastic piece can be guided during the movement of the first connecting piece, so that the stability of the deformation and movement of the first elastic piece can be improved, and then the stability of the electrical connection between the male connector and the female connector can be improved, and the possibility of poor contact can be reduced.

[0033] 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.

[0034] 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 make the first connecting piece approach the central position of the female connector by swinging, so that the stability of the electrical connection between the male connector and the female connector can be improved.

[0035] 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.

[0036] 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.

[0037] 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 of approaching the male connector, thereby improving the stability of the electrical connection between the male connector and the female connector, and meeting the actual use demand better.

[0038] 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;

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] By arranging a plurality of male connectors and female connectors, the stability of the connector assembly and the transmission efficiency of the signal can be improved, and the actual use requirements can be better met.

[0046] 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.

[0047] 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.

[0053] 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.

[0054] 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.

[0089] In order to better understand the technical solutions of the present specification, the embodiments of the present application are described in detail below with reference to the drawings.

[0090] It should be clear that the described embodiments are only some of the embodiments of the present specification, not all the embodiments. Based on the embodiments in the present specification, all other embodiments obtained by a person of ordinary skill in the art without creative labor are within the scope of protection of the present specification.

[0091] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present specification. 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.

[0092] The conductive male head of the pogo pin connector is a spring type probe formed by three basic components of needle shaft, spring and needle tube through precise instrument riveting and pre-pressing, which has good corrosion resistance, mechanical properties and electrical properties, etc., and can usually play the role of current and signal transmission. The needle shaft shrinks a certain length under the extrusion of external force, and the rebound force of 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 large working stroke. The pogo pin connector assembly can be used in electronic devices, including but not limited to mobile phones, tablet computers, notebook computers, styluses, keyboards, etc.

[0093] The electronic device is taken as an example of the stylus 5, and FIG. 1 is a schematic diagram of the structure of the electronic device as the stylus 5. As shown in FIG. 1, the stylus 5 includes a pen barrel 52 and a pen tip structure 51 installed on the pen barrel 52. FIG. 2 is a partial sectional view of FIG. 1, in which the stylus is in an initial state. As shown in FIG. 2, the stylus 5 further includes a connector assembly, which includes a male connector 1 and a female connector 2, the male connector 1 being a male end of the connector assembly, and 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 led out through wires respectively. The male connector and the female connector are installed on the pen tip structure 51 and the pen barrel 52 respectively. In a specific embodiment, the male connector 1 is installed on the pen barrel 52, and the female connector 2 is installed on the pen tip of the pen tip structure 51. In other embodiments, the male connector 1 is installed on the pen tip, and the female connector 2 is installed 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.

[0094] 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 installed 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 electrically 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.

[0095] In the initial state, as shown in FIG. 2, there is a gap between the first connecting piece 12 of the male connector 1 and the female connector 2, and the two cannot achieve signal transmission.

[0096] FIG. 3 is a schematic diagram of the stylus in FIG. 1 in a working state. FIG. 4 is a partial sectional view of the stylus 5 in FIG. 3, in which the stylus 5 is in a working state. As shown in FIG. 3, the stylus 5 is used to input information to a tablet computer 6. As shown in FIG. 4, the pen tip structure 51 can be installed on the pen barrel 52 through a threaded structure, and the pen tip structure 51 and the pen barrel 52 can be relatively moved along the axial direction of the stylus 5 by rotating the pen tip structure 51. Alternatively, the pen tip structure 51 can also be slidably connected with the pen barrel 52, so that the pen tip structure 51 and the pen barrel 52 can be relatively moved along the axial direction of the stylus 5. In the process of the 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. As shown in FIG. 4, when the stylus 5 is in the working state, the male connector 1 and the female connector 2 are electrically connected.

[0097] Generally, the stylus 5 is assembled by first installing the female connector 2 to the tip structure 51, which can serve as a stylus tip, then installing the male connector 1 to the pen barrel 52, and then assembling the tip structure 51 and the pen barrel 52 together. Ideally, the axis of the male connector 1 (which can be approximated as the axis of the first housing 11), the axis of the female connector 2, and the axis of the first connecting member 12 are parallel and on the same line. However, during assembly, due to the fitting accuracy and the fitting tolerance between the components, the positions of the components can deviate within a certain range.

[0098] For example, as shown in FIG. 4, during assembly, the axis of the male connector 1 and the axis of the female connector 2 do not coincide, i.e., they are misaligned. FIG. 4 shows a schematic diagram of the misalignment of the male connector and the female connector during assembly of the stylus 5. As shown in FIG. 4, the axis direction of the female connector 2 and the axis direction of the male connector 1 do not coincide, and they are misaligned. When they are misaligned, the first connecting member 12 is prone to fail to contact the female connector 2, or as shown in FIG. 4, the edge positions of the male connector 1 and the female connector 2 are in contact, which can easily lead to poor contact of the connector assembly and affect signal transmission.

[0099] FIG. 5 is a schematic diagram of the first connecting member being misaligned. During assembly, the first connecting member 12 is misaligned. FIG. 6 shows a schematic diagram of the electrical connection between the male connector 1 and the female connector 2 in FIG. 5. As shown in FIG. 6, as the male connector 1 and the female connector 2 approach each other, the first housing 11 and the first connecting member 12 are in contact along the radial direction, which causes interference between the first housing 11 and the first connecting member 12, hinders the axial movement of the first connecting member 12 along the first housing 11, and causes the first connecting member 12 to be pressed by the female connector 2, which can easily cause the first connecting member 12 to bend. This not only affects the stability of the connection of the connector assembly, but also easily causes damage to the first connecting member 12, affecting the service life of the connector assembly. At the same time, when the outer shell of the tip structure 51 is transparent, the bending of the first connecting member 12 during use can affect the appearance of the electronic device and damage the user's experience.

[0100] Generally, in order to reduce the risk of poor contact between the male connector and the female connector due to the misalignment of the first connecting member, the volume of the female connector 2 is usually increased.

[0101] Fig. 7 shows a partial cross-sectional view of the stylus when the female connector is enlarged. As shown in Fig. 7, the stylus further comprises a plurality of signal terminals. For example, the stylus 5 comprises a TX1 signal, a TX2 signal and a GND signal. 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 shown in Fig. 7, 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 nib 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, resulting in short circuit or signal transmission failure.

[0102] The embodiment of the present application reduces the risk of poor contact caused by misalignment of the male connector and the female connector during use of the electronic device by changing the structure of the connector assembly.

[0103] Fig. 8 is a structural schematic view of the connector assembly in a specific embodiment. As shown in Fig. 8, the embodiment of the present application provides a connector assembly, which comprises 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.

[0104] The male connector 1 comprises a first housing 11, a first connecting piece 12 and a first elastic piece 13. The first housing 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 housing 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 housing 11 has a through hole communicating 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 housing 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 housing 11, the second limiting part 112 can abut against the first limiting part 122, so as to limit the first connecting piece 12 from leaving the first accommodating cavity 111.

[0105] Correspondingly, as shown in FIG. 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 portion 221, and the surface of the guide portion 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, etc. When the male connector 1 and the female connector 2 are close to each other, the first connecting portion 121 abuts against the guide portion 221 to electrically connect the two.

[0106] Please refer to FIG. 9, which shows a schematic view of the abutment of the female connector 2 and the first connecting portion 121 of the male connector 1. In this embodiment, the axis of the male connector 1 and the female connector 2 does not deviate, i.e., the male connector 1 and the female connector 2 are not misaligned. During the abutment of the first connecting portion 121 of the first connecting piece 12 and the guide portion 221, the guide portion 221 can exert a first external force on the first connecting portion 121, and the direction of the first external force is along the axis direction of the first connecting piece 12, so as to move the first connecting piece 12 along the axis direction of the first connecting piece 12 relative to the first housing 11.

[0107] Please refer to FIG. 10, which shows a schematic view of the abutment of the female connector 2 and the first connecting portion 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, i.e., the male connector 1 and the female connector 2 are misaligned. During the abutment of the first connecting portion 121 of the first connecting piece 12 and the guide portion 221, the guide portion 221 can exert a second external force on the first connecting portion 121, and the direction of the second external force is inclined relative to the axis direction of the first connecting piece 12, so as to make the first connecting piece 12 have a tendency to move obliquely relative to the axis direction of the first housing 11 under the action of the second external force.

[0108] At least one of the first limiting portion and the second limiting portion is provided with a guide surface. For example, in the embodiment shown in FIG. 10, the first limiting portion 122 is provided with a first guide surface 141, and the second limiting portion 112 is provided with a second guide surface 142. During the movement of the first connecting piece 12 relative to the first housing 11, the first guide surface 141 and the second guide surface 142 can be fitted, so as to enable the first connecting piece 12 to swing relative to the first housing 11. The first guide surface 141 and the second guide surface 142 can be arc surfaces, or can be spherical surfaces. Along the radial direction of the first connecting piece 12, there is a first gap 15 between the first connecting portion 121 of the first connecting piece 12 and the through hole of the first housing 11. The first guide surface 141 and the second guide surface 142 enable the first connecting piece 12 to swing relative to the first housing 11, and the first gap 15 prevents the first housing 11 from limiting the swinging of the first connecting piece 12 relative to the first housing 11.

[0109] In a possible implementation, the size of the first gap is 0.2 mm to 1 mm. For example, the size of the first gap can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm.

[0110] 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 setting the first gap, reduce the possibility of contact between the first connecting piece and the second limiting portion during the swing, and thus reduce the possibility of interference between the first connecting piece and the first shell during the swing, which is conducive to improving the stability of the movement of the first connecting piece and reducing the possibility of deformation of the first connecting piece under pressure.

[0111] Please refer to FIG. 11, which shows a schematic view of the swing of the first connecting piece 12 relative to the first shell 11 after the abutment of the female connector 2 and the first connecting portion 121 of the male connector 1. Under the action of the second external force, the first connecting piece 12 swings relative to the shell to the position shown in FIG. 11, at which time the axis of the first connecting piece 12 and the axis of the first shell 11 have an included angle, i.e., the axis of the first connecting piece 12 and the axis of the first shell 11 are not parallel.

[0112] Please refer to FIG. 12, which shows a schematic view of the continued mutual approach of the female connector 2 and the male connector 1. Under the action of the second external force, the first connecting piece 12 continues to move in a direction away from the female connector 2, compresses the first elastic member 13, and causes the first guide surface 141 and the second guide surface 142 to disengage from each other, and the first connecting piece 12 continues to swing in a direction close to the center of the female connector 2, thereby facilitating the stability of the connection of the first connecting piece 12 and the female connector 2 and more meeting the actual use requirements. In addition, under the action of the second external force, the first connecting piece 12 will not be bent, so that the possibility of deformation of the first connecting piece 12 under pressure can be reduced under the condition of improving the stability of the connection of the male connector 1 and the female connector 2, thereby the possibility of damage of the first connecting piece 12 can be reduced.

[0113] Please continue to refer to FIG. 13, which is a schematic view of the male connector 1 and the female connector 2 returning to the initial state. 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 piece 12 swings in the opposite direction and gradually resets.

[0114] Please continue to refer to FIG. 14, which shows a schematic view of the first connecting piece 12 and the first shell 11 having an angle during the assembly process, i.e., the first connecting piece 12 is misaligned. During 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, causing the first connecting piece 12 to swing 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 during the swing of the first connecting piece 12. In addition, by providing 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 during the swing of the first connecting piece 12 can be reduced, thereby facilitating the swing of the first connecting piece to the center position of the guide part 221, so as to improve the connection stability between the male connector 1 and the female connector 2.

[0115] Please continue to refer to FIG. 15, which shows a structural schematic view of the male connector 1 and the female connector 2 continuing to approach each other. As shown in FIG. 15, the male connector 1 and the female connector 2 continue to approach each other, causing the first connecting piece 12 to 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, i.e., the misaligned first connecting piece 12 can be corrected, so that the first connecting piece 12 moves towards the center of the female connector 2 by swinging while moving along the axial direction of the first shell 11, thereby improving the stability of the connection between the first connecting piece 12 and the female connector 2 and better meeting the actual use requirements.

[0116] In addition, the above scheme does not need to increase the volume of the female connector to improve the stability of the connection 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 multiple 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 members between adjacent female connectors can also be reduced.

[0117] As shown in FIG. 15, in this embodiment, the first limiting portion 122 is provided with a first guide surface 141, and 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, and the contact area therebetween is relatively large, which is beneficial to improve the stability of the first connecting piece 12 when it swings relative to the first housing 11, thereby improving the connection stability of the male connector 1 and the female connector 2.

[0118] 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.

[0119] In this embodiment, 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 FIG. 16, which shows a 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, and the second limiting portion 112 is not provided with the guide surface. The outer edge of the second limiting portion 112 is used to abut against the guide surface 14, and the cross section of the second limiting portion 112 can be rectangular. 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, thereby making the first connecting piece 12 close to the center position of the female connector 2, and correcting the deviation, so as to improve the connection stability of the male connector 1 and the female connector 2.

[0120] As shown in FIG. 17, FIG. 17 shows a structure diagram of the guide surface 14 arranged at the first limiting part 122. In a possible implementation, the second limiting part 112 is provided with the guide surface 14, the first limiting part 122 is not provided with a 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.

[0121] As shown in FIG. 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 close to each other, the first connecting piece 12 moves relative to the first housing 11, and the first elastic member 13 linearly deforms, and generally, 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 close to the female connector 2. Through such a 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.

[0122] As shown in FIG. 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. Meanwhile, when the first connecting piece 12 moves relative to the first housing 11 and the first elastic member 13 deforms elastically, the sleeving manner 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.

[0123] Specifically, as shown in FIG. 17, 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.

[0124] Please continue to refer to FIG. 18, which shows a structure diagram of the first elastic piece 13 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. A 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.

[0125] 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.

[0126] As shown in FIG. 18, in a possible implementation, along the radial direction of the first connecting piece 12, there is a second gap 16 between the second connecting portion 123 and the inner wall of the first accommodating cavity 111, and the size of the second gap 16 is 0.2mm to 1.5mm. The size of the second gap 16 can be 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.4mm, 1.5mm, etc.

[0127] 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 make the first connecting piece close to the center position of the female connector, thereby improving the stability of the electrical connection between the male connector and the female connector.

[0128] As shown in FIG. 18, in one possible implementation, one of the first connecting part 121 and the guiding part 221 is provided with a protruding part 121a, and the other is provided with a recessed part 221a. When the male connector 1 and the female connector 2 are matched, at least part of the protruding part 121a can extend into the recessed part 221a.

[0129] Through such 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 matched, thereby facilitating the improvement of the stability of the contact between the male connector and the female connector, and thus the possibility of poor contact can be reduced.

[0130] As shown in FIG. 18, in one possible implementation, the first connecting part 121 is provided with a protruding part 121a, and the recessed part 221a is located in the guiding part 221 and recessed to the inside of the guiding part 221. The end of the first connecting part 12 away from the first accommodating cavity 111 can serve as the protruding part 121a. The end of the first connecting part 12 away from the first accommodating cavity 111 can be arc-shaped. The recessed part 221a can be arc-shaped recessed. Specifically, the surface of the recessed part 221a in contact with the protruding part 121a is a spherical surface, and the surface of the protruding part 121a in contact with the recessed part 221a is a spherical surface.

[0131] Through such design, when the male connector and the female connector are misaligned, the first connecting part is in contact with the inner wall of the recessed part, at this time, the force direction of the first connecting part and the axial direction of the male connector have an included angle, so that the first connecting part can move relative to the first housing along the guiding surface, thereby causing the first connecting part to swing, and at the same time, as the male connector and the female connector approach each other, the first connecting part moves along the inner wall of the recessed part to the center position of the recessed part, 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.

[0132] The spherical surfaces of the surfaces in contact with each other of the protruding part and the recessed part can make the first connecting part receive forces in different directions when the male connector and the female connector have errors in different directions during matching, so that the first connecting part swings in different directions, and the first connecting part 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.

[0133] As shown in FIG. 19, in a possible implementation, the shapes of the protrusion 121a and the recess 221a are correspondingly arranged, and the cross-sectional shape of the protrusion 121a and the recess 221a can be arc-shaped, triangular, trapezoidal, or the like. The inner surface of the recess 221a and the outer surface of the protrusion 121a can have an arc surface, an inclined surface, or the like, to facilitate guiding 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 better meeting actual use requirements.

[0134] The scheme provided in the embodiments of the present application sets a gap between the first connecting piece and the first shell and sets an arc-shaped guiding surface between the first limiting portion and the second limiting portion, so that the first connecting piece can swing. 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 electrical connection between the male connector and the female connector, and reduces the possibility of deformation of the first connecting piece under pressure during connection and the possibility of damage to the first connecting piece.

[0135] As shown in FIG. 20, in a possible implementation, the first connecting piece 12 and the second limiting portion 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.

[0136] During assembly of the male connector, when the first connecting piece is inclined, the first connecting piece will extrude the second elastic piece, and the second elastic piece will be deformed. The restoring force generated by the deformation of the second elastic piece can act on the first connecting piece to move the first connecting piece in the opposite direction of the inclination, so as to straighten the first connecting piece, thereby improving the relative position accuracy of the first connecting piece and the first shell, thereby reducing the possibility of inclination of the first connecting piece during installation, or reducing the degree of inclination of the axis of the first connecting piece relative to the axis of the first shell.

[0137] During the process of approaching 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 directly contact 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, which is conducive to prolonging the service life of the first connecting piece and the connector assembly.

[0138] As shown in FIG. 21, 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 is connected with the third elastic piece 23 and is 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.

[0139] 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.

[0140] As shown in FIG. 21, which is a schematic view of the female connector 2, in a possible implementation, the second connecting member 22 comprises a third limiting portion 222, which is arranged along the circumference of the guide portion 221. The second housing 21 is provided with a fourth limiting portion 212, which is 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 against each other, for limiting the second connecting member 22 from disengaging 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 each other through the arc-shaped surface. Specifically, the arc-shaped surface can be a spherical surface. As shown in FIG. 21, in a possible implementation, the third limiting portion 222 is provided with a first arc-shaped surface 212a, and the fourth limiting portion 212 is provided with a second arc-shaped surface 222a. The structures of the third limiting portion 222 and the fourth limiting portion 212 can be similar to those of the first limiting portion 122 and the second limiting portion 112, i.e., at least part of the first arc-shaped surface 212a and / or at least part of the second arc-shaped surface 222a is an arc-shaped surface. The third limiting portion 222 and the fourth limiting portion 212 can move relative to each other along the first arc-shaped surface 212a and the second arc-shaped 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 connecting member 22 can swing relative to the second housing 21. By providing the third limiting portion 222 and the fourth limiting portion 212 with arc-shaped surfaces, the contact area of the third limiting portion 222 and the fourth limiting portion 212 can be increased, and the stability of the relative movement of the third limiting portion 222 and the fourth limiting portion 212 can be improved. The third gap 24 is used to increase the space for swinging of the second connecting member 22, and reduce the possibility of interference between the second connecting member 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 move closer to each other, because the force direction of the first connecting member 12 and the force direction of the second connecting member 22 are not in the same straight line, the first connecting member 12 and the second connecting member 22 can swing, so as to adjust the relative positions of the first connecting member 12 and the second connecting member 22, improve the relative position accuracy of the first connecting member 12 and the second connecting member 22, improve the stability of the electrical connection of the male connector 1 and the female connector 2, and better meet the actual use requirements.

[0141] Please refer to FIG. 22, which is a schematic diagram of the connector assembly provided by the embodiment of the application applied to a stylus. The connector assembly shown in FIGS. 8 to 21 can be applied to a stylus, specifically, FIG. 22 is a schematic diagram of the connector assembly shown in FIG. 9 applied to a stylus 5. In the illustrated scheme, the female connector 2 is arranged in a nib structure 51, and the male connector is arranged in a pen barrel 52. In use, the nib structure 52 is driven to move relative to the pen barrel 52 along the axial direction of the stylus, so that the female connector 2 and the male connector 1 are in contact to achieve electrical connection, thereby transmitting the signal input by the user.

[0142] When the connector assembly is applied to a stylus, the end of the connector assembly away from the nib structure can also be provided with a first connecting piece, that is, the opposite ends of the male connector are respectively provided with a first connecting piece along the axial direction of the connector assembly, and the two first connecting pieces are respectively used for electrical connection with the female connector arranged in the nib structure and the female connector arranged in 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 to compress the first elastic piece. 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 tendencies, that is, the two first connecting pieces respectively have a tendency to move towards the corresponding female connector, thereby facilitating the stability of the connection between each first connecting piece and the corresponding female connector.

[0143] 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.

[0144] Please refer to FIG. 23, which shows a schematic diagram of the connector assembly including 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 the number of female connectors 2 are the same, and the number of male connectors 1 and the number of female connectors 2 can be two, three, four, etc. respectively. In use, each male connector 1 cooperates with the corresponding female connector 2 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.

[0145] As shown in FIG. 24, FIG. 24 is a structural schematic diagram of the electronic device being 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). Generally, the user of the tablet computer has the need of typing input, and thus the tablet products of various manufacturers will push the keyboard (such as the keyboard) accessories corresponding to the tablet to support the functions of the keys, the touch pad, the near field communication (NFC), and the like. The keyboard corresponding to the tablet computer can adopt the pogo pin to realize the data transmission. Specifically, the tablet computer and the keyboard can realize the data transmission through the connector assembly shown in FIG. 23.

[0146] As shown in FIG. 23, the connector assembly can further include a first main body part 3 and a second main body part 4, the male connectors 1 are arranged on the first main body part 3, and the female connectors 2 are arranged on the second main body part 4. That is, the plurality of male connectors 1 are integrated on the first main body part 3, and the plurality of female connectors 2 are integrated on the second main body part 4. The first main body part 3 and the second main 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, and the installation in the tablet computer and the keyboard is facilitated. The first main body part 3 and the second main body part 4 can be separate housings, or can be structural members such as housings of the tablet computer and the keyboard.

[0147] As shown in FIG. 24, 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 case that the male connectors 1 are arranged on the tablet computer 6 and the female connectors 2 are arranged on the keyboard 7 is described as an example. The arrangement positions of the male connectors 1 and the female connectors 2 are shown in the dotted box in FIG. 24.

[0148] Specifically, the male connectors are arranged on the bottom of the tablet computer, and the female connectors are arranged on the upper surface of the keyboard and are staggered with the keys of the keyboard.

[0149] FIG. 25 is a structural schematic diagram of the connector assembly in FIG. 24. As shown in FIG. 25, in order to realize the data transmission between the tablet computer and the keyboard, the connector assembly can include three male connectors 1 and three female connectors 2.

[0150] Similar to the foregoing stylus, as shown in FIG. 25, during assembly, the connector assembly connecting the tablet computer 6 and the keyboard 7 also has the problem of mispositioning and skewing of some components. For example, there is a risk of misalignment of the male connector 1 and the female connector 2, i.e., there is a risk of skewing of the first connecting member of the male connector 1 relative to the axis of the first housing, i.e., there is a risk of mispositioning of the first connecting member.

[0151] In the embodiment shown in FIG. 25, the misalignment of the male connector 1 and the female connector 2 is described as an example. When the male connector 1 and the female connector 2 are misaligned, the first connecting member of the male connector 1 deviates from the preset position, and thus there is a possibility that the first connecting member contacts the edge of the female connector 2 or fails to contact the female connector 2, which easily leads to poor contact, resulting in poor connection reliability of the male connector and the female connector and affecting data transmission between the tablet computer and the keyboard.

[0152] As shown in FIG. 26, in order to reduce the risk of mispositioning of the male connector 1 and the female connector 2 leading to poor contact, the size of the female connector 2 can be increased to improve the connection stability. However, increasing the size of the female connector 2 leads to a decrease in the spacing between adjacent female connectors 2, and in the use process, the male connector 1 and the female connector 2 are easily misaligned and miscontacted, leading to short circuit and the like. At the same time, due to the decrease in the spacing between adjacent female connectors 2, the size of the structural member between adjacent female connectors 2 is also decreased, resulting in a decrease in the structural strength of the region, which is easily deformed under force and even damaged.

[0153] As shown in FIG. 27, it is a partial schematic view of the connector assembly provided by the embodiment of the present application applied to a tablet computer and a keyboard. As shown in FIG. 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, and 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 in the tablet computer and the keyboard can be improved, thereby improving the stability of the electrical connection of the male connector 1 and the female connector 2 and more meeting the actual use requirements.

[0154] As shown in FIG. 27, in one possible implementation, among the tablet computer and the keyboard, one is provided with the magnetic member 32, and the other is provided with the matching member 42, which can be a component with magnetism or a component capable of being adsorbed by the magnetic member 32. The magnetic member 32 and the matching member 42 can be magnetically adsorbed and connected. In use, the tablet computer and the keyboard can be positioned by the magnetic adsorption and connection of the magnetic member 32 and the matching member 42, and when the tablet computer and the keyboard are misaligned, the deviation can be corrected by the adsorption force between the magnetic member 32 and the matching member 42, thereby improving the relative position accuracy of the male connector 1 and the female connector 2 and being conducive to improving the stability of the electrical connection of the male connector 1 and the female connector 2.

[0155] FIG. 28 is a partial enlarged view of part I in FIG. 27. As shown in FIG. 28, the first connecting member 12 of the male connector 1 is provided with a first guide surface 141, and the first housing 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 member 12 is misaligned, in the process of the cooperation of the male connector 1 and the female connector 2, the first connecting member 12 can move along the second guide surface 142 relative to the first housing 11 by the first guide surface 141, thereby swinging to make the end of the first connecting member 12 toward the female connector 2 swing toward the center of the female connector. The first gap 15 is used to provide a space for swinging, so as to reduce the possibility of interference between the first connecting member 12 and the first housing 11 in the process of swinging. The first connecting member 12 can also be corrected in the process of swinging, thereby being capable of adjusting the relative position of the first connecting member 12 and the female connector 2 when the male connector 1 and the female connector 2 are misaligned or the first connecting member 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 of the tablet computer and the keyboard, the stability of the connection of the tablet computer and the keyboard can be improved, which is more in line with the actual use requirements.

[0156] Meanwhile, as shown in FIG. 27, on the basis of the swing of the first connecting member 12, the limiting protrusion 31 and the magnetic member 32 are arranged on the tablet computer, and the limiting recess 41 and the matching member 42 are arranged on the keyboard. Correspondingly, the magnetic member 32 and the matching member 42 can be magnetically adsorbed 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 in the process of the connection of the male connector 1 and the female connector 2, and can also play a role in deviation correction to a certain extent. Meanwhile, on the basis of the magnetic adsorption and limiting and the concave-convex matching and limiting, the deviation is corrected by the swing of the first connecting member, which is conducive to further improving the stability of the connection between the male connector 1 and the female connector 2.

[0157] As shown in FIG. 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 member 32 and the matching member 42 can be pre-positioned, which can prevent mistakes and improve the relative position accuracy of the male connector 1 and the female connector 2, thereby 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 member 12, and the magnetic attraction is combined with the swing of the first connecting member 12. Compared with the scheme of limiting the male connector and the female connector 2 by the magnet, in the scheme provided in FIG. 27, the male connector 1 and the female connector 2 are pre-positioned by magnetic attraction, which can prevent mistakes, reduce the relative position error between the tablet computer and the keyboard, and further adjust the relative position between the first connecting member and the guide portion by the swing of the first connecting member. Since the first connecting member can adjust its position by swinging, the installation accuracy requirement and the matching accuracy requirement of the magnetic member 32 and the matching member 42 can be reduced. The pre-positioning of the male connector 1 and the female connector 2 by the magnetic member 32 and the matching member 42 and the swing of the first connecting member can further improve the connection accuracy of the male connector and the female connector, thereby improving the connection stability.

[0158] In summary, the scheme provided in the embodiments of the present application can adjust the angle and position of the first connecting member by the swing of the first connecting member, and perform self-adaptive correction, so as to improve the stability of the connection of the male connector and the female connector without increasing the volume of the female connector. Meanwhile, the first recess is arranged on the female connector, which can increase the surface area of the female connector without increasing the volume of the female connector, thereby facilitating the electrical connection of the male connector and the female connector. The first elastic member is sleeved on the first connecting member, which can improve the stability of the connection of the first elastic member and the first connecting member, and further improve the stability of the movement of the first connecting member relative to the first housing.

[0159] When the first main body and the second main body are housings for integrating the male connector and the female connector, the magnetic member, the matching member, the limiting protrusion and the limiting recess can be arranged on the first main body or the second main body according to actual use requirements.

[0160] In a possible implementation, the connector assembly provided in the embodiments of the present application can also be applied to electronic devices such as mobile phones and notebook computers.
