[0033] In the related art, the commonly used magnetic attraction connector has the problem that the interface module cannot be adapted to the host of the magnetic attraction connector when the model or type of the interface device changes. Therefore, the embodiment of the present application provides a magnetic attraction connector with replaceable interface, which can replace the interface module, so that the terminal device can be adapted to different types or types of interface modules through the magnetic attraction connection of the replaceable interface, which can effectively expand the application range of the magnetic attraction connector with replaceable interface, thereby improving the user experience. The structure of the magnetic attraction connector with replaceable interface will be described in detail below.

[0034] Figure 1 The structure diagram of the magnetic attraction connector with replaceable interface 100 provided by the embodiment is shown in the figure; Figure 2 The exploded view of the magnetic attraction connector with replaceable interface 100 provided by the embodiment is shown in the figure Figure 1 ; Figure 3 The exploded view of the magnetic attraction connector with replaceable interface 100 provided by the embodiment is shown in the figure Figure 2 ; Figure 4 The partial sectional view of the magnetic attraction connector with replaceable interface 100 provided by the embodiment is shown in the figure. Please refer to Figures 1 to 4 , the magnetic attraction connector with replaceable interface 100 provided by the embodiment specifically includes an auxiliary agent and a replaceable interface module 109.

[0035] In detail, the host 101 is the main frame structure of the entire magnetic attraction connector with replaceable interface 100, which is roughly in the shape of a hollow rectangular parallelepiped. At the same time, the host 101 has a mounting cavity 103, which is a cavity with an open end 137 at the top, which allows the replaceable interface module 109 to be accommodated in the mounting cavity 103 through the open end 137, to ensure the safety and stability of the replaceable interface module 109 during use. In addition, the mounting cavity 103 is provided with a circuit board 105, so that the host 101 can be in communication with the replaceable interface module 109 on the one hand, and can also be used for communication with the external terminal device on the other hand.

[0036] In detail, the replaceable interface module 109 specifically comprises a shell 111 and an interface module 113 detachably mounted in the shell 111. The shell 111 is magnetically mounted in the mounting cavity 103 through the opening 137, so that the stability of the cooperation between the entire replaceable interface module 109 and the host 101 is ensured. Meanwhile, the interface module 113 is provided with cooperating contacts, and the interface module 113 is used for external interface equipment to communicate the interface equipment and the terminal equipment when the cooperating contacts cooperate with the circuit board 105. Through the arrangement of the interface module 113, when the wired earphone, USB or HDMI interface equipment needs to be matched with the terminal equipment, the interface module 113 can be first matched with the host 101, so that the cooperating contacts cooperate with the circuit board 105, and then the wired earphone, USB or HDMI interface equipment is inserted into the interface module 113, and the interface module 113 is matched.

[0037] That is, through such an arrangement, when the terminal equipment needs to be matched with different types and models of wired earphones, USB or HDMI interface equipment, only the interface module 113 needs to be replaced, and thus the terminal equipment can be adapted to different types or categories of interface modules 113 through the replaceable interface magnetic attraction connector 100, so that the application range of the replaceable interface magnetic attraction connector 100 can be effectively expanded, and the user experience can be improved.

[0038] Please refer again to Figures 1 to 4 In order to ensure that the interface module 113 can be safely and reliably arranged in the shell 111, in the embodiment, the shell 111 is also arranged in a substantially cuboid structure, and the shell 111 is internally formed with a receiving cavity 112, and the first opening 115 and the second opening 117 are arranged on the side wall of the shell 111. The first opening 115 is located at the bottom of the shell 111 and is arranged close to the host 101 to facilitate cooperation with the host 101, and the second opening 117 is located at the side of the shell 111 and is used for the wired earphone, USB or HDMI interface equipment to be inserted. Of course, in other embodiments, the first opening 115 and the second opening 117 can also be arranged on different side walls of the shell 111 according to requirements, as long as the interface equipment can be stably communicated to the terminal equipment through the interface module 113, and the present embodiment is not limited.

[0039] In detail, the interface module 113 is detachably accommodated in the accommodating cavity 112. Moreover, the mating contact is arranged on the interface module 113 close to the first opening 115 and can be exposed from the first opening 115 to mate with the circuit board 105 in the host 101. Meanwhile, the interface module 113 has an interface part 121 which is a structure for the interface module 113 to mate with the interface device such as a wired earphone, a USB or an HDMI. The port of the interface part 121 can be exposed from the second opening 117 to allow a user to insert the interface device, so as to facilitate the interface device to stably mate with the host 101 through the interface module 113.

[0040] As an optional solution, in the embodiment, the shell 111 further has a third opening 119 which communicates with the accommodating cavity 112 and is arranged on the side of the shell 111 and spaced apart from the second opening 117. The third opening 119 is provided with an end plate 123 which is used to open or close the third opening 119 and abuts against the end of the interface module 113 when the third opening 119 is closed. Through the arrangement of the end plate 123, on one hand, the installation, dismounting and maintenance of the interface module 113 can be facilitated, and on the other hand, the interface module 113 can be stabilized when the third opening 119 is closed, so as to ensure that the interface module 113 can stably mate with the host 101. Of course, in other embodiments, the third opening 119 can not be arranged, and the side wall opposite to the second opening 117 is integrally formed with the shell 111, so as to ensure the convenience of the installation and dismounting of the interface module 113, which is not limited in the embodiment.

[0041] Please refer to Figures 1 to 4 , in order to realize the stability and reliability of the cooperation between the host 101 and the replaceable interface module 109, in the embodiment, the first magnetic attraction member 129 is arranged on the host 101, and the second magnetic attraction member 131 is arranged on the corresponding position of the replaceable interface module 109. The first magnetic attraction member 129 and the second magnetic attraction member 131 are opposite in polarity to magnetically connect the host 101 and the replaceable interface module 109. Through the arrangement of the first magnetic attraction member 129 and the second magnetic attraction member 131, the replaceable interface module 109 can be stably attracted to the host 101, so that the cooperation relationship between the host 101 and the replaceable interface module 109 in the vertical direction is more stable, and the replaceable interface module 109 is not easy to be separated from the host 101 through the opening 137, so as to ensure the safety and reliability of the magnetic attraction connector 100 of the entire replaceable interface during use.

[0042] In detail, the bottom wall of the host 101 is provided with a mounting groove 133, and the first magnetic member 129 is mounted in the mounting groove 133; the second magnetic member 131 is arranged at the bottom of the shell 111 and is used to cooperate with the first magnetic member 129. The first magnetic member 129 is arranged in the mounting groove 133, which is beneficial to guarantee the stability and reliability of the cooperation between the first magnetic member 129 and the host 101. The first magnetic member 129 is arranged at the bottom wall of the host 101, and the second magnetic member 131 is arranged at the bottom of the shell 111, so that the distance between the first magnetic member 129 and the second magnetic member 131 is closer after the replaceable interface module 109 is mounted in the mounting cavity 103 of the host 101, thereby more fully guaranteeing the stability and reliability of the magnetic attraction connector 100 of the replaceable interface during use. Of course, in other embodiments, the mounting positions of the first magnetic member 129 and the second magnetic member 131 can also be adjusted according to requirements, as long as the stable attraction between the two can be guaranteed, and the present embodiment is not limited.

[0043] As an optional solution, since the cooperation of the first magnetic member 129 and the second magnetic member 131 has guaranteed the stability of the replaceable interface module 109 and the host 101 in the vertical direction. Thus, in order to further improve the stability of the replaceable interface module 109 and the host 101 in the left-right direction and the front-rear direction, in the present embodiment, one of the shell 111 and the host 101 is provided with a notch 125, and the other of the shell 111 and the host 101 is provided with a guide block 127, the guide block 127 is inserted and matched with the notch 125, so as to fully guarantee the stability of the replaceable interface module 109 and the host 101 in the left-right direction and the front-rear direction, and further make the movement of the replaceable module in each direction be constrained by the host 101, thereby guaranteeing the stability and reliability of the magnetic attraction connector 100 of the replaceable interface during use.

[0044] In detail, in the present embodiment, the shell 111 is circumferentially provided with a plurality of guide blocks 127, and the host 101 is correspondingly provided with a plurality of notches 125, and the plurality of guide blocks 127 and the plurality of notches 125 are one-to-one inserted and matched. Through the cooperation of the plurality of guide blocks 127 and the plurality of notches 125, the stability of the replaceable interface module 109 after being mounted in the host 101 can be further improved, and the safety and reliability of the operation process can be fully guaranteed.

[0045] More specifically, please refer to Figures 1 to 4The two sides of the shell 111 are provided with a guide block 127 extending in the vertical direction. The two opposite side walls of the main machine 101 are provided with a notch 125 extending in the vertical direction. The two guide blocks 127 and the two notches 125 are one-to-one matched and inserted, and part of each guide block 127 can extend out of the installation cavity 103 through the corresponding notch 125. Through the setting of the two vertically extending guide blocks 127 and the vertically extending notches 125, the stability of the replaceable interface module 109 and the main machine 101 in the left-right direction and the front-back direction is ensured, so that the movement of the replaceable module in each direction is constrained by the main machine 101. At the same time, since part of the guide block 127 can extend out of the installation cavity 103 through the corresponding notch 125, the user can also separate or install the replaceable interface module 109 by pulling this part of the structure, thereby effectively improving the installation, disassembly and maintenance efficiency of the magnetic connector 100 of the replaceable interface; and since the guide block 127 and the notch 125 cooperate to guide the cooperation between the replaceable interface module 109 and the main machine 101, the installation, disassembly and maintenance efficiency is further improved.

[0046] Further optionally, in the present embodiment, the outer side of the part of each guide block 127 extending out of the installation cavity 103 from the corresponding notch 125 is further provided with a friction pattern 139, which is a plurality of protruding structures arranged at intervals, which can increase the friction between the guide part and the user's hand, thereby further facilitating the user to separate or install the replaceable interface module 109 by pulling this part of the structure, thereby further improving the installation, disassembly and maintenance efficiency of the magnetic connector 100 of the replaceable interface.

[0047] Please refer again to Figures 1 to 4 In the present embodiment, the circuit board 105 is a PCB module, and the circuit board 105 is provided with a plurality of pogo pins 107. The mating contact is an FPC contact, and the interface module 113 is provided with a plurality of mating contacts corresponding to the plurality of pogo pins 107. Through such a setting, when the replaceable interface module 109 is installed in the installation cavity 103 of the main machine 101, the plurality of pogo pins 107 and the plurality of mating contacts are one-to-one matched, thereby enabling the interface device and the terminal device, and also facilitating the replacement of different interface devices by replacing the interface module 113.

[0048] In detail, in the embodiment, five pogo pins 107 are arranged on the circuit board 105, and four of the five pogo pins 107 are arranged in a rectangular array, and the other pogo pin 107 is arranged at the center of the rectangle. Correspondingly, the number of the matching contacts is also five, and the five matching contacts are arranged one by one to correspond to the five pogo pins 107, so as to fully ensure the stability and reliability of the cooperation between the replaceable interface module 109 and the host 101. Of course, in other embodiments, the number of the pogo pins 107 on the circuit board 105 can also be set to be multiple, for example, six, seven or even more, and the number of the matching contacts can be adjusted accordingly; at the same time, even if the circuit board 105 still includes five pogo pins 107, the five pogo pins 107 can also be arranged in a row or a column, and not necessarily arranged in the structure shown in the figure, as long as the stability and reliability of the cooperation between the replaceable interface module 109 and the host 101 can be ensured, and the embodiment is not limited.

[0049] In addition, please refer again to Figure 1 It should be further pointed out that, in the embodiment, the host 101 is also provided with an SR wiring module 135, one end of the SR wiring module 135 is electrically connected with the circuit board 105, and the other end of the SR wiring module 135 is connected with a terminal device, so as to fully ensure that the wired earphone, USB or HDMI interface device can be sequentially adapted with the terminal device through the matching contact, the circuit board 105 and the SR wiring module 135, and the normal use of the interface device is ensured.

[0050] The working principle and beneficial effects of the replaceable interface magnetic attraction connector 100 provided by the embodiment of the application will be described in detail as follows:

[0051] When the wired earphone, USB or HDMI interface device and the terminal device are connected by using the replaceable interface magnetic attraction connector 100, the interface module 113 can be placed in the shell 111 to form the replaceable interface module 109, and then the whole replaceable interface module 109 is matched with the mounting cavity 103 of the host 101 from top to bottom through the opening 137, so that the notch 125 is matched and inserted with the guide block 127, and the pogo pin 107 on the circuit board 105 is matched with the matching contact; then, the SR wiring module 135 is connected with the terminal device, and the wired earphone, USB or HDMI interface device is inserted into the interface module 113.

[0052] In the above process, if it is necessary to replace the interface device, the interface module 113 matched with the interface device can be replaced.
