Referring to fig. 1 to 6, in an embodiment of the present application, a connector 100 is provided, which is suitable for a mobile terminal 200. The connector 100 includes: at least one first metal dome 110, one end 120 of the first metal dome 110 is disposed inside the frame 210 of the mobile terminal 200 and connected to a main pcb 220 carried by the frame 210, and the other end 130 of the first metal dome 110 is disposed on a first outer surface 211 of the frame 210 of the mobile terminal 200, as shown in fig. 5, and is configured to contact a second metal dome 320 of a second outer surface 301 of an external device (300 shown in fig. 7) disposed outside, so that the first metal dome 110 is electrically connected to the second metal dome 320.

Specifically, in some embodiments of the present application, the end portion 120 of the first metal dome 110 protrudes out of the bottom surface 212 of the frame 210 and is in contact connection with a contact point (not shown) on a main pcb 220 carried by the frame 210. The contact points on the main pcb 220 are connected to a main control chip (not shown) disposed on the main pcb 220, so that signals reaching the main control chip can be output from the first metal dome 110. Optionally, if the size of the mobile terminal 200 is larger or the distance between the main pcb 220 and the end 120 of the first metal dome 110 is larger, the main pcb 220 may be electrically connected through a flexible pcb (not shown) or a bonding wire. The flexible printed circuit board has the characteristics of ultra-thin thickness, small volume, light weight and the like, and therefore, the flexible printed circuit board can be preferably used for connecting the end portion 120 of the first metal dome 110 with the main printed circuit board 220. In the present embodiment, the flexible printed circuit board may be disposed inside the frame 210, but is not limited thereto.

Further, in some embodiments of the present application, the first metal dome 110 is mounted on the frame 210 of the mobile terminal 200 by injection molding. Due to the injection molding manner, the other end 130 of the first metal dome 110 is disposed on a first outer surface 211 of the frame 210 of the mobile terminal 200, and there is no need to form a hole on the first outer surface 211 like an earphone socket or a USB socket, so that the design can improve the waterproof performance of the mobile terminal 200.

In the implementation of the present application, the first metal elastic pieces 110 are multiple and arranged in parallel at intervals. The arrangement enables the other end portions 130 of the first metal elastic pieces 110 to be arranged on the first outer surface 211 at intervals, so as to avoid the influence on signal transmission caused by the contact between the other end portions 130 of each first metal elastic piece 110. One end 120 of each of the first metal dome 110 is arranged in sequence and is in contact connection with the main pcb 220.

Further, since the first metal elastic pieces 110 are arranged in parallel at intervals and are injection molded, the plurality of first metal elastic pieces 110 only occupy a space with a thickness of one first metal elastic piece, wherein the thickness is a height H that the end portion 120 of the first metal elastic piece 110 protrudes from the bottom surface 212 of the frame body 210, see fig. 2. The thickness H ranges from 0.1mm to 0.2 mm. Compared with a USB socket or an earphone seat, the arrangement can greatly improve the utilization rate of the structural space of the mobile terminal 200.

In some embodiments of the present application, the number of the first metal dome 110 is at least three. Specifically, as shown in fig. 3, the first metal dome 110 at the two most sides arranged along the first direction V is configured to transmit a power-on signal to detect whether the mobile terminal 200 is connected or disconnected with the external device 300, and the remaining first metal domes 110 are configured to transmit a signal from the mobile terminal 200 to the external device 300 when the mobile terminal 200 is connected with the external device 300. Wherein the first direction V is a horizontal axis direction of the mobile terminal 200. The two side-most first metal dome 110 refer to the left-most first metal dome 141 and the right-most first metal dome 142, as shown in fig. 3 and 4. The two first metal elastic sheets (141, 142) are used as pins for measuring the on-off between the mobile terminal 200 and the external device 300 when the mobile terminal 200 is powered on. In addition, as shown in fig. 3, the remaining first metal dome 143 is used to transmit various types of signals. The signal may be an analog signal, but is not limited thereto, and may also be a digital signal. If classified according to function, the signal may be an audio signal, a video signal, a communication signal, or the like. Therefore, the remaining first metal dome 143 can be used as a signal outlet of the mobile terminal 200 for transmitting to the external device 300. In addition, a specific connection mode between the mobile terminal 200 and the external device 300 will be further described below.

It should be noted that, when the number of the first metal dome 110 is one or two, a power-on signal may be provided to the first metal dome, and the connection or disconnection between the mobile terminal 200 and the external device 300 is detected through the first metal dome 110, and when it is determined that the mobile terminal 200 and the external device 300 are connected, the same first metal dome 110 is still used for signal transmission to transmit to the external device 300 (as shown in fig. 7).

According to yet another aspect of the present application, an embodiment of the present application provides a mobile terminal 200. As shown in fig. 3, the mobile terminal 200 includes: a frame 210, wherein the frame 210 is used for carrying a main printed circuit board 220; at least one first metal dome 110, wherein one end 120 of the first metal dome 110 is disposed inside the frame 210 and connected to a main pcb 220 carried by the frame 210, and the other end 130 of the first metal dome 110 is disposed on a first outer surface 211 of the frame 210 and is used for contacting with a second metal dome 320 of a second outer surface 301 of an external device (300 shown in fig. 7) disposed outside, so that the first metal dome 110 is electrically connected to the second metal dome 320; and a magnetic sensitive switch 230, wherein the magnetic sensitive switch 230 is disposed on the main pcb 220 and near the first metal dome 110, and the magnetic sensitive switch 230 is configured to send an Interrupt signal (IRQ) to the first Interrupt pin 221 of the main pcb 220 when the first metal dome 110 contacts the second metal dome 320, so that the first metal dome 110 transmits a power-on signal under the control of the main pcb 220.

In this embodiment, the mobile terminal 200 includes the first metal dome 110, and the structure thereof is not described herein again.

The material of the first metal dome 110 may be copper, aluminum, etc., but is not limited thereto. The other end 130 of the first metal dome 110 is disposed on a first outer surface 211 of the frame 210. Specifically, in some embodiments, the other end 130 may protrude from the first outer surface 211 and form a small plane for connecting with a pin corner (or a terminal corner) of an external device 300 (e.g., an external speaker). In other embodiments, the other end 130 may be flush with the first outer surface 211.

The number of the first metal dome 110 is at least three, and one of the first metal domes 142 (shown in fig. 4) of the first metal domes 110 at the two sides arranged along the first direction V is electrically connected to the second interrupt pin 222 of the main pcb 220 for outputting an electrifying signal. The main pcb 220 is configured to determine the power-on signal, and allow the remaining first metal dome 110 to transmit a signal from the mobile terminal 200 to the external device 300 when the power-on signal is determined to be at a high level.

In this embodiment, the number of the first metal dome 110 is five. As shown in fig. 3 and 4, the first metal dome (141, 142) arranged at the leftmost side and the rightmost side along the horizontal axis direction of the mobile terminal 200 is used for transmitting a power-on signal to detect whether the mobile terminal 200 is connected or disconnected with the external device 300. Specifically, the main pcb 220 is electrically connected to the first metal dome 141 on the leftmost side through a GPIO pin (not shown) or a power pin. The second interrupt pin 222 of the main pcb 220 is electrically connected to the rightmost first metal dome 142, as shown in fig. 4. An end portion (not labeled) of the second metal dome 320 is disposed on a second outer surface 301 of the external device 300, wherein the number of the second metal domes 320 is the same as the number of the first metal domes 110, and a disposition position of the end portion of the second metal dome 320 corresponds to a disposition position of the other end portion 130 of the first metal dome 110. It should be noted that the two second metal elastic sheets 320 at the two extreme sides, which are arranged along the second direction (not labeled in the figures, the direction corresponds to the first direction, and refer to the first direction V), are connected, as shown in fig. 4, so that when the first metal elastic sheet 110 contacts with the second metal elastic sheet 320, a loop formed by the first metal elastic sheets (141, 142) at the two extreme sides and the second metal elastic sheets (231, 232) at the two extreme sides can be formed, and the loop is used for detecting whether the mobile terminal 200 and the external device 300 are firmly connected.

As shown in fig. 4, in the present embodiment, when the first metal dome 141 on the mobile terminal 200 closest to the left receives a power-on signal sent by the main pcb 220, the power-on signal passes through the second metal dome 231 on the external device 300 closest to the left, the second metal dome 232 on the external device 300 closest to the right, and the first metal dome 142 on the mobile terminal 200 closest to the left in sequence, and is transmitted to the second interrupt pin 222 of the main pcb 220. The mobile terminal 200 may determine based on the received power-up signal on the second interrupt pin 222. When the level of the power-on signal is determined to be a high level, it indicates that the connection between the mobile terminal 200 and the external device 300 is correct. Then, the mobile terminal 200 may control the remaining first metal dome 143 of the mobile terminal 200 to perform signal transmission so as to transmit the signal to the external device 300, for example, transmit an audio signal. If any one of the first metal elastic sheets (141, 142) at the two sides of the mobile terminal 200 is disconnected, the loop is not conducted. Accordingly, the mobile terminal 200 may determine that the level of the power-on signal received on the second interrupt pin 222 is low. This indicates that the connection between the mobile terminal 200 and the external device 300 is in a disconnected state, and the reason for the disconnected state is that the external device 300 (or the expansion accessory) is in an abnormally connected state, or the external device 300 (or the expansion accessory) is in a disconnected state. At this time, the main pcb 220 prohibits the remaining first metal dome 143 from transmitting signals from the mobile terminal 200 to the external device 300.

Further, a magnetic sensitive switch 230 is disposed on the mobile terminal 200, as shown in fig. 3. In this embodiment, the magnetic sensitive switch 230 is a Hall switch, such as, but not limited to, the type S-5712ACDL1-14T1U, as shown in FIG. 6. In some embodiments, the magnetic sensitive switch 230 may be an electronic device that is acted on by a magnetic field to perform a switching operation.

Specifically, when the external device 300 approaches the mobile terminal 200, the hall switch disposed on the mobile terminal 200 is acted by the magnetic field generated by the external device 300 to perform a switching operation. Then, the hall switch sends an interrupt signal to the first interrupt pin 221 of the main pcb 220, as shown in fig. 6, so that the first metal dome 110 transmits a power-on signal under the control of the main pcb 220. With reference to fig. 4, further, when the first metal dome 141 on the mobile terminal 200 closest to the left receives a power-on signal sent by the main pcb 220, the power-on signal passes through the second metal dome 231 on the external device 300 closest to the left, the second metal dome 232 on the external device 300 closest to the right, and the first metal dome 142 on the mobile terminal 200 closest to the left in sequence, and is transmitted to the second interrupt pin 222 of the main pcb 220. The mobile terminal 200 may determine based on the received power-up signal on the second interrupt pin 222. When the level of the power-on signal is determined to be a high level, it indicates that the connection between the mobile terminal 200 and the external device 300 is correct. It should be noted that, when the mobile terminal 200 is in the normal standby state, the hall switch is in the off state, and the first metal dome 110 is not electrified. By such design, the first metal dome 110 exposed by the mobile terminal 200 can be effectively prevented from being erroneously triggered to perform signal transmission by being erroneously contacted with other conductors (not shown), and even an electric leakage phenomenon may be generated, so that the safety of the mobile terminal 200 itself or the external device 300 is further enhanced.

Referring to fig. 4 to 8, according to another aspect of the present application, an embodiment of the present application further provides an electronic device 400, which includes: the mobile terminal 200 as described above, as shown in fig. 8; and an external device 300, as shown in fig. 7, a magnet 310 is disposed on the external device 300, and the magnet 310 is used for triggering the operation of the magnetic sensitive switch 230.

Specifically, a magnet 310 is disposed on the external device 300, and the magnet is used for triggering the operation of the magnetic sensitive switch 230.

In this embodiment, the structure of the mobile terminal 200 is as described above, and is not described herein again.

Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The input unit 930 may be used to receive input numeric or character information and generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, the input unit 930 may include a touch-sensitive surface 931 as well as other input devices 932. The touch-sensitive surface 931, also referred to as a touch screen or a touch pad, may collect touch operations by a user on or near the touch-sensitive surface 931 (e.g., operations by a user on or near the touch-sensitive surface 931 using a finger, a stylus, or any other suitable object or attachment) and drive the corresponding connecting device according to a predetermined program. Alternatively, the touch sensitive surface 931 may include both a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 980, and can receive and execute commands sent by the processor 980. In addition, the touch sensitive surface 931 may be implemented in various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 930 may also include other input devices 932 in addition to the touch-sensitive surface 931.

The Display unit 940 may include a Display panel 941, and optionally, the Display panel 941 may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch-sensitive surface 931 may overlay the display panel 941, and when a touch operation is detected on or near the touch-sensitive surface 931, the touch operation is transmitted to the processor 980 to determine the type of touch event, and the processor 980 then provides a corresponding visual output on the display panel 941 according to the type of touch event. Although in FIG. 9 the touch-sensitive surface 931 and the display panel 941 are implemented as two separate components, in some embodiments the touch-sensitive surface 931 and the display panel 941 may be integrated to implement input and output functions.

The mobile terminal 900 may also include at least one sensor 950, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel 941 according to the brightness of ambient light, and a proximity sensor that may turn off the display panel 941 and/or backlight when the mobile terminal 900 is moved to the ear. As one of the motion sensors, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when the mobile phone is stationary, and can be used for applications of recognizing the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be further configured on the mobile terminal 900, further description is omitted here.

The audio circuit 960 may transmit the electrical signal converted from the received audio data to the speaker 961, and convert the electrical signal into a sound signal for output by the speaker 961; on the other hand, the microphone 962 converts the collected sound signal into an electric signal, converts the electric signal into audio data after being received by the audio circuit 960, and outputs the audio data to the processor 980 for processing, and then transmits the audio data to another terminal via the RF circuit 910, or outputs the audio data to the memory 920 for further processing. The audio circuit 960 may also include an earbud jack to provide communication of peripheral headphones with the mobile terminal 900.

The mobile terminal 900, which may assist the user in e-mail, web browsing, and streaming media access, etc., provides the user with wireless broadband internet access via a transport module 970 (e.g., a Wi-Fi module). Although fig. 9 shows the transmission module 970, it is understood that it does not belong to the essential constitution of the mobile terminal 900 and can be omitted entirely within the scope not changing the essence of the invention as needed.
