Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, and particularly relates to a pair of headphones. Background Art

[0002] Open Wearable Stereo (OWS) headphones are a type of headphones that do not need to go deep into the ear canal and maintain an open design, emphasizing comfort, environmental perception ability, and suitability for long-term wearing.

[0003] OWS headphones generally include a sound output body and a connecting bridge. The sound output body is used to face the user's ear canal to achieve the sound generation function, and the connecting bridge is usually used to clamp the user's auricle to achieve the wearing of OWS headphones. In the related art, since the sound output body and the connecting bridge cannot be easily disassembled, when after-sales repair of OWS headphones is required, the common strategy is to replace them with new ones, which is not convenient for after-sales repair. Summary of the Invention

[0004] This application aims to provide a pair of headphones that can solve the technical problem of inconvenient after-sales repair of headphones in the related art.

[0005] An embodiment of this application provides a pair of headphones, including:

[0006] A sound output part;

[0007] A connecting part, detachably connected to the sound output part, and the connecting part is used to clamp the user's ear;

[0008] A first limiting component, arranged on the sound output part and / or the connecting part;

[0009] A second limiting component, arranged on the sound output part and / or the connecting part;

[0010] Wherein, when the sound output part is connected to the connecting part, the first limiting component is used to limit the separation of the sound output part and the connecting part from each other, and the second limiting component is used to limit the relative rotation of the sound output part and the connecting part.

[0011] In the embodiment of the present application, by setting the sound output part and the connection part of the earphone to be detachably connected, when the earphone fails, the earphone can be detached from the sound output part, so that the faulty part can be repaired without replacing the whole earphone, which facilitates the after-sales repair of the earphone. Correspondingly, when the earphone fails, it can be disassembled and repaired without overall replacement, thus effectively reducing the after-sales repair cost of the earphone. Further, through the arrangement of the first limiting component and the second limiting component, when the sound output part and the connection part are in a connected state, it can not only ensure that the sound output part and the connection part will not be separated, but also ensure that there is no relative rotation between the sound output part and the connection part, thereby ensuring the stability of the relative position between the sound output part and the connection part and the stability of the overall structure of the earphone.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0025] The following combines Figures 1 to 6 Describe the earphone according to the embodiment of the present application.

[0026] In some embodiments of the present application, an earphone is provided. Figure 1 The block diagram of the earphone according to the embodiment of the present application is shown; Figure 5 The second structural schematic diagram of the earphone according to the embodiment of the present application is shown; As Figure 1 And Figure 5As shown in the figure, the earphone 100 includes: a sound output part 102; a connection part 104 detachably connected to the sound output part 102, and the connection part 104 is used to clamp the user's ear; a first limiting component 106 arranged on the sound output part 102 and / or the connection part 104; a second limiting component 108 arranged on the sound output part 102 and / or the connection part 104; wherein, when the sound output part 102 is connected to the connection part 104, the sound output part 102 is connected to the connection part 104, the first limiting component 106 is used to limit the sound output part 102 and the connection part 104 from separating from each other, and the second limiting component 108 is used to limit the sound output part 102 and the connection part 104 from rotating relative to each other.

[0027] In an embodiment of the present application, the earphone 100 may include a sound output part 102 and a connection part 104. Among them, the sound output part 102 may be used to emit sound to realize the sound-emitting function of the earphone 100. Correspondingly, the connection part 104 may be used to clamp the user's ear to realize the wearing of the earphone 100.

[0028] Among them, the sound output part 102 and the connection part 104 may be set to be detachably connected. In this way, when the sound output part 102 of the earphone 100 or the connection part 104 of the earphone 100 is damaged or fails, the earphone 100 can be disassembled from the sound output part 102, so as to repair the damaged earphone 100 or the sound output part 102. After the repair is completed, the sound output part 102 and the earphone 100 can be connected.

[0029] That is to say, by setting the earphone 100 and the sound output part 102 to be detachably connected, when the earphone 100 fails, the earphone 100 can be disassembled from the sound output part 102, so as to repair the faulty part, which facilitates the after-sales repair of the earphone 100. At the same time, when the earphone 100 fails, the earphone 100 can be disassembled and repaired instead of being replaced as a whole, thus effectively reducing the after-sales repair cost of the earphone 100.

[0030] Further, the earphone 100 further includes a first limiting component 106 and a second limiting component 108. Among them, when the sound output part 102 and the connection part 104 are in a connected state, the first limiting component 106 is used to limit the sound output part 102 and the connection part 104 from separating from each other. Thus, the first limiting component 106 ensures the stability of the relative position between the sound output part 102 and the connection part 104, and avoids the separation between the sound output part 102 and the connection part 104.

[0031] Exemplarily, the first limiting component 106 can be arranged on the sound output part 102. When the sound output part 102 and the connecting part 104 are in a connected state, the connection between the first limiting component 106 on the sound output part 102 and the connecting part 104 can ensure that the sound output part 102 and the connecting part 104 will not be separated. Correspondingly, the first limiting component 106 can also be arranged on the sound output part 102. When the sound output part 102 and the connecting part 104 are in a connected state, the connection between the first limiting component 106 on the connecting part 104 and the sound output part 102 can ensure that the sound output part 102 and the connecting part 104 will not be separated. For example, the first limiting component 106 can be set as a hook, which is arranged on the sound output part 102 or on the connecting part 104. When the sound output part 102 and the connecting part 104 are connected, the shell of the connecting part 104 or the shell of the sound output part 102 is clamped by the hook to limit the separation between the sound output part 102 and the connecting part 104. Or, the first limiting component 106 can be set as a two-piece structure, that is, one part of the first limiting piece is arranged on the sound output part 102, and the other part is arranged on the connecting part 104. When the sound output part 102 and the connecting part 104 are connected, the connection between the two parts of the first limiting component 106 is used to limit the separation between the sound output part 102 and the connecting part 104.

[0032] Furthermore, the second limiting component 108 is used to limit the relative rotation between the sound output part 102 and the connecting part 104. That is, through the second limiting component 108, when the sound output part 102 and the connecting part 104 are connected to each other, it can be ensured that relative rotation occurs between the sound output part 102 and the connecting part 104, thereby avoiding relative displacement between the sound output part 102 and the connecting part 104, and further ensuring the stability of the relative position between the sound output part 102 and the connecting part 104, and ensuring the stability of the overall structure of the earphone 100.

[0033] Exemplarily, the second limiting component 108 can be arranged on the sound output part 102. When the sound output part 102 and the connecting part 104 are in a connected state, by connecting between the second limiting component 108 on the sound output part 102 and the connecting part 104, it can be ensured that the sound output part 102 and the connecting part 104 will not rotate relative to each other. Correspondingly, the second limiting component 108 can also be arranged on the sound output part 102. When the sound output part 102 and the connecting part 104 are in a connected state, by connecting between the second limiting component 108 on the connecting part 104 and the sound output part 102, it can be ensured that the sound output part 102 and the connecting part 104 will not rotate relative to each other. For example, the second limiting component 108 can be set as a hook or a clamping member, which is arranged on the sound output part 102 or on the connecting part 104. When the sound output part 102 is connected to the connecting part 104, the shell of the connecting part 104 or the shell of the sound output part 102 is clamped or held by the hook or the clamping member to limit the rotation between the sound output part 102 and the connecting part 104. Or, the second limiting component 108 can be set as a two-piece structure, that is, a part of the second limiting component 108 is arranged on the sound output part 102, and the other part is arranged on the connecting part 104. For example, a part of the second limiting component 108 is a limiting protrusion, and the other part is a clamping groove. When the sound output part 102 is connected to the connecting part 104, the relative rotation between the sound output part 102 and the connecting part 104 is limited by clamping the limiting protrusion into the clamping groove.

[0034] In the embodiment of the present application, by setting the connection between the sound output part 102 and the connecting part 104 of the earphone 100 as detachable, when the earphone 100 fails, the earphone 100 can be disassembled from the sound output part 102, so that the faulty part can be repaired without replacing the whole earphone 100, which facilitates the after-sales repair of the earphone 100. Correspondingly, when the earphone 100 fails, it can be disassembled and repaired without replacing the whole, thus effectively reducing the after-sales repair cost of the earphone 100. Further, through the arrangement of the first limiting component 106 and the second limiting component 108, when the sound output part 102 and the connecting part 104 are in a connected state, it can be ensured that the sound output part 102 and the connecting part 104 will not separate from each other, and it can also be ensured that the sound output part 102 and the connecting part 104 will not rotate relative to each other, thereby ensuring the stability of the relative position between the sound output part 102 and the connecting part 104 and the stability of the overall structure of the earphone 100.

[0035] In some embodiments of the present application, Figure 2 shows Figure 1 the structural schematic diagram of the sound output part in Figure 3 shows Figure 1 one of the structural schematic diagrams of the connecting part inFigure 4 shows Figure 1 the second structural schematic diagram of the connecting part in Figure 2 ; as Figure 3 、 Figure 4 and Figure 5 shown, the first limiting component 106 includes: a first limiting retaining ring 110, which is arranged on the sound output part 102; a second limiting retaining ring 112, which is arranged on the connecting part 104; wherein, when the sound output part 102 is connected to the connecting part 104, the first limiting retaining ring 110 and the second limiting retaining ring 112 are in limiting cooperation to limit the separation of the sound output part 102 and the connecting part 104 from each other.

[0036] In the embodiment of the present application, the first limiting component 106 may include a first limiting retaining ring 110 and a second limiting retaining ring 112, wherein the first limiting retaining ring 110 is arranged on the sound output part 102, and correspondingly, the second limiting retaining ring 112 is arranged on the connecting part 104.

[0037] Specifically, the first limiting retaining ring 110 may be arranged in a ring shape along the circumferential direction of the sound output part 102, and the second limiting retaining ring 112 may be arranged in a ring shape along the circumferential direction of the connecting part 104. When the sound output part 102 is connected to the connecting part 104, in the direction of separation between the sound output part 102 and the connecting part 104, at least a part of the first limiting retaining ring 110 and the second limiting retaining ring 112 overlap. In this way, when the sound output part 102 is connected to the connecting part 104, the first limiting retaining ring 110 and the second limiting retaining ring 112 can be in contact with each other to achieve limiting cooperation, and further, the separation between the sound output part 102 and the connecting part 104 is restricted by the first limiting retaining ring 110 and the second limiting retaining ring 112, ensuring the stability of the connection between the sound output part 102 and the connecting part 104.

[0038] In some embodiments of the present application, as Figure 2 shown, the first limiting retaining ring 110 includes an avoidance notch 114; wherein, during the connection process of the sound output part 102 and the connecting part 104, the connecting part 104 drives the second limiting retaining ring 112 to pass through the avoidance notch 114 and rotates the second limiting retaining ring 112 to make the first limiting retaining ring 110 and the second limiting retaining ring 112 in limiting cooperation.

[0039] In the embodiment of the present application, the first limiting retaining ring 110 may include an avoidance notch 114, which can be used to avoid the second limiting retaining ring 112 during the connection process between the sound output part 102 and the connecting part 104, so as to ensure the normal connection between the sound output part 102 and the connecting part 104, that is, to avoid interference between the first limiting retaining ring 110 and the second limiting retaining ring 112 during the connection process.

[0040] Specifically, during the process of connecting the sound outlet 102 and the connecting portion 104, the sound outlet 102 and the connecting portion 104 are brought closer together until the second limit stop ring 112 on the connecting portion 104 passes through the avoidance gap 114 of the first limit stop ring 110 on the sound outlet 102. Figure 2 As shown by the middle arrow, the connecting part 104 is rotated or the sound output part 102 is rotated to drive the second limit stop ring 112 to rotate relative to the first limit stop ring 110, until the first limit stop ring 110 and the second limit stop ring 112 can be limitedly matched with each other, thereby completing the connection between the sound output part 102 and the connecting part 104, and at the same time, the separation between the sound output part 102 and the connecting part 104 is limited by the first limit stop ring 110 and the second limit stop ring 112.

[0041] It can be understood that, in the process of the sound output part 102 and the connecting part 104 approaching each other, the second limit stop ring 112 can pass through the avoidance gap 114 of the first limit stop ring 110, and then after the connecting part 104 or the sound output part 102 is rotated, the second limit stop ring 112 and the avoidance gap 114 of the first limit stop ring 110 will be staggered, so that the second limit stop ring 112 cannot pass through the avoidance gap 114 on the first limit stop ring 110 again, thereby realizing the limitation of the separation between the sound output part 102 and the connecting part 104 by the first limit stop ring 110 and the second limit stop ring 112.

[0042] In some embodiments of the present application, Figure 2 , Figure 3 and Figure 4 As shown, the sound outlet portion 102 includes: a first shell 116, the first shell 116 is provided with a mounting hole 118, and a first limit retaining ring 110 is arranged on the hole wall of the mounting hole 118; the connecting portion 104 includes: a second shell 120, the second limit retaining ring 112 is arranged on the side wall of the second shell 120 along the circumferential direction of the side wall of the second shell 120, and along the circumferential direction of the side wall of the second shell 120, the length of the second limit retaining ring 112 is less than the length of the avoidance gap 114; wherein, when the sound outlet portion 102 is connected to the connecting portion 104, a portion of the second shell 120 extends into the mounting hole 118.

[0043] In the embodiment of the present application, the sound output portion 102 may include a first shell 116, and a mounting hole 118 may be opened on the first shell 116. Correspondingly, the connecting portion 104 may include a second shell 120. When the sound output portion 102 and the connecting portion 104 are connected, a portion of the second shell 120 may be extended into the mounting hole 118.

[0044] Further, the first limiting retaining ring 110 can be arranged on the hole wall of the mounting hole 118 of the first housing 116. Correspondingly, the second limiting retaining ring 112 can be arranged along the circumferential direction of the side wall of the second housing 120 on the side wall of the second housing 120, and along the circumferential direction of the side wall of the second housing 120, the length of the second limiting retaining ring 112 is less than the length of the avoidance notch 114. In this way, during the process of connecting the sound output part 102 and the connecting part 104, the second housing 120 can be inserted into the mounting hole 118. At this time, the second limiting retaining ring 112 can be opposite to the avoidance notch 114 of the first limiting retaining ring 110 on the hole wall of the mounting hole 118. Until after the second limiting retaining ring 112 passes through the avoidance notch 114, rotate the second housing 120 so that the second limiting retaining ring 112 is displaced from the avoidance notch 114 until the first limiting retaining ring 110 and the second limiting retaining ring 112 can be in limiting cooperation, then the connection between the sound output part 102 and the connecting part 104 can be completed. At the same time, since the second limiting retaining ring 112 is displaced from the avoidance notch 114 of the first limiting retaining ring 110, the separation between the sound output part 102 and the connecting part 104 can be restricted by the first limiting retaining ring 110 and the second limiting retaining ring 112.

[0045] In some embodiments of the present application, as Figure 3 , Figure 4 and Figure 5 shown, the earphone 100 further includes: a sealing ring 122, the sealing ring 122 is arranged on the side wall of the second housing 120. When the sound output part 102 is connected to the connecting part 104, the sealing ring 122 abuts against the hole wall of the mounting hole 118.

[0046] In an embodiment of the present application, the earphone 100 may further include a sealing ring 122. The sealing ring 122 can be arranged on the side wall of the second housing 120 of the connecting part 104. When the sound output part 102 is connected to the connecting part 104, since the second housing 120 of the connecting part 104 is located in the mounting hole 118 of the first housing 116 of the sound output part 102, the sealing ring 122 can abut against the side wall of the mounting hole 118, and further, the gap between the first housing 116 and the second housing 120 can be sealed by the sealing ring 122, preventing external water, dust and other impurities from entering the interior of the sound output part 102 or the connecting part 104 through the gap between the first housing 116 and the second housing 120.

[0047] Specifically, the sealing ring 122 can be made of silica gel material. When the sound output part 102 is connected to the connecting part 104, the sealing ring 122 can abut against the hole wall of the mounting hole 118 of the first housing 116 and undergo elastic deformation, thereby increasing the contact area between the sealing ring 122 and the hole wall of the mounting hole 118, and further improving the sealing effect of the sealing ring 122.

[0048] In some embodiments of the present application, such as Figure 2 , Figure 4 and Figure 5 shown, the second limiting component 108 includes: a first magnetic attraction part 124, disposed on the bottom wall of the mounting hole 118; a second magnetic attraction part 126, disposed at the end of the second housing 120; wherein, when the sound output part 102 is connected to the connecting part 104, the first magnetic attraction part 124 and the second magnetic attraction part 126 are attracted to each other.

[0049] In the embodiments of the present application, the second limiting component 108 may include a first magnetic attraction part 124 and a second magnetic attraction part 126, that is, when the sound output part 102 is connected to the connecting part 104, the relative rotation between the sound output part 102 and the connecting part 104 is restricted by the magnetic attraction force between the first magnetic attraction part 124 and the second magnetic attraction part 126.

[0050] Wherein, the first magnetic attraction part 124 may be disposed on the sound output part 102, specifically on the bottom wall of the mounting hole 118, and the second magnetic attraction part 126 may be disposed on the connecting part 104, specifically at the end of the second housing 120. When the sound output part 102 is connected to the connecting part 104, the first magnetic attraction part 124 and the second magnetic attraction part 126 are opposite in position, so that a magnetic attraction force is generated between the first magnetic attraction part 124 and the second magnetic attraction part 126, causing the first magnetic attraction part 124 and the second magnetic attraction part 126 to be attracted to each other.

[0051] Exemplarily, the first magnetic attraction part 124 may be disposed on the hole wall of the mounting hole 118 of the first housing 116 of the sound output part 102. Correspondingly, the second magnetic attraction part 126 may be disposed at the end of the second housing 120 of the connecting part 104. When the sound output part 102 is connected to the connecting part 104, the first magnetic attraction part 124 on the hole wall of the mounting hole 118 and the second magnetic attraction part 126 at the end of the second housing 120 are opposite in position, thus generating a magnetic attraction force. Or, the first magnetic attraction part 124 may be provided with a boss on the hole wall of the mounting hole 118, and the first magnetic attraction part 124 is disposed on the boss. Correspondingly, the second magnetic attraction part 126 may be disposed at the end of the second housing 120. When the sound output part 102 is connected to the connecting part 104, the end of the second housing 120 is opposite to the boss on the hole wall of the mounting hole 118, and the second magnetic attraction part 126 at the end of the second housing 120 and the first magnetic attraction part 124 on the boss are opposite in position, thus generating a magnetic attraction force.

[0052] Specifically, both the first magnetic attraction part 124 and the second magnetic attraction part 126 can include a plurality of magnets. When the sound output part 102 is connected to the connection part 104, the positions of the plurality of magnets of the first magnetic attraction part 124 correspond to those of the plurality of magnets of the second magnetic attraction part 126 one by one, and the magnetic poles are opposite, so as to ensure that a magnetic attraction force can be generated between the first magnetic attraction part 124 and the second magnetic attraction part 126.

[0053] In some embodiments of the present application, such as Figure 1 , Figure 3 and Figure 5 shown, the connection part 104 includes: a first electrical connection component 130; the sound output part 102 includes: a second electrical connection component 132. When the sound output part 102 is connected to the connection part 104, the first electrical connection component 130 and the second electrical connection component 132 are electrically connected.

[0054] The earphone 100 may further include a control part 128. The control part 128 can be connected to the sound output part 102 through the connection part 104. Through the control part 128, the operation process of the sound output part 102 can be controlled. Specifically, the sound parameters of the sound output part 102 can be controlled, etc. A battery may also be provided in the control part 128 to supply power to the sound output part 102 to ensure that the sound output part 102 can operate continuously.

[0055] In the embodiments of the present application, the connection part 104 includes a first electrical connection component 130, and the sound output part 102 includes a second electrical connection component 132. When the sound output part 102 is connected to the connection part 104, the first electrical connection component 130 and the second electrical connection component 132 are electrically connected.

[0056] In addition, the earphone 100 may further include a control part 128. The control part 128 can be connected to the sound output part 102 through the connection part 104. Through the control part 128, the operation process of the sound output part 102 can be controlled. Specifically, the sound parameters of the sound output part 102 can be controlled, etc. A battery may also be provided in the control part 128 to supply power to the sound output part 102 to ensure that the sound output part 102 can operate continuously.

[0057] Specifically, when the sound output part 102 is connected to the connection part 104, the first electrical connection component 130 and the second electrical connection component 132 are electrically connected, so as to realize the electrical connection between the sound output part 102 and the control part 128 through the first electrical connection component 130 and the second electrical connection component 132, to ensure that the control part 128 can transmit a control signal to the sound output part 102, and further realize the control of the sound parameters of the sound output part 102.

Wherein, when the sound output portion 102 is connected to the connection portion 104, the plurality of connection contacts 142 are connected to the plurality of connection contacts 136 in a one-to-one correspondence.

[0059] In an embodiment of the present application, the first electrical connection component 130 may include a first circuit board 134, and the first circuit board 134 may be disposed inside the second housing 120 of the connection portion 104, specifically, it may be located at one end of the second housing 120. On the first circuit board 134, a plurality of connection contacts 136 may also be provided, and the connection contacts 136 may be used for electrical connection with the second electrical connection component 132 of the sound output portion 102 when the connection portion 104 is connected to the sound output portion 102.

[0060] Further, the second electrical connection component 132 includes a second circuit board 140, and the second circuit board 140 may be disposed inside the first housing 116 of the sound output portion 102, specifically, it may be disposed within the mounting hole 118 of the first housing 116. On the second circuit board 140, a plurality of connection contacts 142 may also be provided. When the sound output portion 102 is connected to the connection portion 104, the plurality of connection contacts 142 are connected to the plurality of connection contacts 136 on the first circuit board 134 in a one-to-one correspondence, thereby realizing the electrical connection between the first electrical connection component 130 and the second electrical connection component 132. It realizes the electrical connection between the sound output portion 102 and the control portion 128 through the first electrical connection component 130 and the second electrical connection component 132, so as to ensure that the control portion 128 can transmit control signals to the sound output portion 102, and further realize the control of the sound parameters of the sound output portion 102.

[0061] By providing the plurality of connection contacts 136 on the first circuit board 134 and the plurality of connection contacts 142 on the second circuit board 140, when the sound output portion 102 is connected to the connection portion 104, the electrical connection between the first electrical connection component 130 and the second electrical connection component 132 can be realized by means of the abutment between the connection contacts 136 and the connection contacts 142, which not only ensures the electrical connection between the first electrical connection component 130 and the second electrical connection component 132, but also does not affect the disassembly between the sound output portion 102 and the connection portion 104.

[0062] In addition, the first electrical connection component 130 further includes a flexible circuit board 138. One end of the flexible circuit board 138 is electrically connected to the first circuit board 134, and the other end of the flexible circuit board 138 can pass through the second housing 120 of the connecting portion 104 and be electrically connected to the control portion 128. It can be understood that the connecting portion 104 can be used to clamp the user's ear. Therefore, the connecting portion 104 is usually a flexible structure to achieve shape change. By providing the flexible circuit board 138, it can cooperate with the shape change of the connecting portion 104 to ensure that when the shape of the connecting portion 104 changes, the first circuit board 134 can be effectively electrically connected to the control portion 128.

[0063] In some embodiments of the present application, Figure 6 shows Figure 5 a schematic structural diagram of the connection contact in, as Figure 6 shown, the connection contact 142 includes: a housing 144 provided on the second circuit board 140; an elastic member 146 provided in the housing 144; an abutting member 148, a part of the abutting member 148 is provided in the housing 144, and the first end of the abutting member 148 is connected to the elastic member 146; wherein, when the sound output portion 102 is connected to the connecting portion 104, the second end of the abutting member 148 abuts against the connection contact 136 and drives the elastic member 146 to undergo elastic deformation, and when the sound output portion 102 is not connected to the connecting portion 104, the elastic member 146 restores elastic deformation.

[0064] In an embodiment of the present application, the connection contact 142 may include a housing 144, an elastic member 146, and an abutting member 148. Among them, the housing 144 is provided on the second circuit board 140, the elastic member 146 is provided in the housing 144, a part of the abutting member 148 is provided in the housing 144, and the first end of the abutting member 148 abuts against the elastic member 146. Correspondingly, the second end of the abutting member 148 is located outside the housing 144.

[0065] Specifically, when the sound output part 102 is connected to the connection part 104, the second end of the abutting part 148 can be used to abut against the connection contact 136 on the first circuit board 134, so as to realize the electrical connection between the first electrical connection component 130 and the second electrical connection component 132. While the abutting part 148 abuts against the connection contact 136, the abutting part 148 can also compress the elastic part 146, so that the elastic part 146 undergoes elastic deformation. It can be understood that since the elastic part 146 undergoes elastic deformation, a thrust is provided to the abutting part 148, so that the second end of the abutting part 148 can tightly abut against the connection contact 136 on the first circuit board 134, thereby ensuring the stability of the connection between the abutting part 148 and the connection contact 136, avoiding the occurrence of virtual connection between the abutting part 148 and the connection contact 136, and further ensuring the stability of the electrical connection between the first electrical connection component 130 and the second electrical connection component 132.
