At present, the input/output (I/O) interfaces of mobile phones, tablets and other terminal products mostly bear the only charging and data transmission functions, and their functions are irreplaceable. Therefore, the requirements for the refinement of the charging interface, the reliability requirements in the scenarios of headphone cable drops, and daily headphone and cable plugging and unplugging are increasing. It is necessary to ensure the above characteristics through high-cost post-processing and structural coordination. The structure is relatively complex, which increases the cost of the whole machine and is contrary to the development trend of thinness and miniaturization of the whole machine.

In the present application, the cable plug can be inserted into the connection cavity and connected to the connector, so that the user can charge or transmit data to the electronic device. In the process of inserting the cable plug along the inner wall of the connection, the abutment surface can limit the cable plug along the insertion direction of the cable plug, that is, when the cable plug is connected to the connector, the cable plug can contact the abutment surface to prevent the cable plug from continuing to extend, and the insertion force generated by the cable plug during the insertion process can be completely borne by the abutment surface, so as to avoid the connector being subjected to external force and causing the connection failure with other components in the installation cavity, affecting the use function of the connector, ensuring the connection stability of the electronic device during daily use or falling, improving the connection reliability between the electronic device and the cable plug, and improving the service life of the electronic device. At the same time, since there is no need to set an additional limiting component that can limit the connector in the installation cavity, the structural complexity and manufacturing difficulty of the electronic device are reduced, the cost is saved, and the space in the installation cavity is saved, which is conducive to the design of thin and small electronic devices. In addition, the connecting cavity is arranged in the shell, and the connecting inner wall of the connecting cavity is made of consistent material and color, and the connecting inner wall will not discolor due to wear during the insertion of the cable plug, thereby improving the refinement of the interior of the connecting cavity and the integrity of the overall design. There is no need for additional plating treatment on the connecting inner wall, which further saves costs.

In a possible design, the electronic device further includes a circuit board, which is installed in the installation cavity and connected to the connector.

In the present solution, when the abutment portion is formed on the shell by injection molding, the connection strength between the abutment portion and the shell is high and it is not easy to separate from the shell, so that the insertion force when the cable plug abuts the abutment portion can be transmitted to the shell, thereby improving the reliability of the abutment portion, and allowing the abutment portion and the shell to be made of different materials to meet the hardness or material requirements of different parts of the casing, etc., thereby saving manufacturing costs.

In a possible design, the shell is made of aluminum alloy, and the abutting portion is made of plastic.

In this solution, when the shell is made of aluminum alloy, it has higher hardness and lighter weight, which makes the shell more wear-resistant and drop-resistant, while reducing the weight of the whole machine, which is conducive to the lightweight design of the whole machine. In addition, the material of the abutment part is plastic, which saves the manufacturing cost of the casing and is not easy to deform, further improving the reliability of the abutment part.

In a possible design, the abutment portion is annular and is radially arranged at a position where the shell is located in the connecting channel.

In the present scheme, when the abutting portion is annular, the area of the abutting surface between the abutting portion and the cable plug can be increased, so that the abutting portion can withstand a greater insertion force, and the force on the abutting portion is more uniform, further avoiding damage to the abutting portion. When the abutting portion is annular, the inner wall of the channel in the connecting channel is smooth and has no protrusions, which can reduce the gap between the channel wall and the connector, thereby facilitating waterproof settings.

In a possible design, the abutting portions are protrusions distributed at intervals at positions of the shell located on the connecting channel.

In this solution, when the abutting portions are protrusions distributed at intervals, the use of manufacturing materials can be reduced, and the weight of the casing can be reduced, thereby facilitating a more lightweight design of the entire electronic device.

In a possible design, the connector includes a connecting portion and a tongue core, the connecting portion is fixed in the connecting channel, the tongue core is fixedly connected to a side of the connecting portion close to the connecting cavity, and is at least partially located in the connecting cavity.

In this solution, the connection part is fixed in the connection channel, so that the tongue core can be suspended in the connection cavity, which is convenient for mating with the cable plug. Moreover, the connection part is fixed in the connection channel, which can improve the connection stability of the connector and limit the displacement of the connector in the connection channel, thereby ensuring that the position and extension of the tongue core in the connection cavity remain unchanged, avoiding failure of the connection between the cable plug and the tongue core, thereby ensuring the effectiveness of the cable plug inserted into the connection cavity to be mating with the tongue core, and improving the connection reliability between the electronic device and the cable plug.

In a possible design, the connecting portion includes an end surface facing one side of the connecting cavity, and the end surface is located in the connecting channel.

In this solution, the connecting part is retracted into the connecting channel, which can avoid abutment interference with the cable plug inserted into the connecting cavity, ensure that the cable plug can directly abut against the abutment part after being inserted into the connecting cavity, and the abutment part bears the entire insertion force, thereby improving the protection of the connector, further ensuring the connection stability of the connector, and improving the connection reliability between the electronic device and the cable plug.

In a possible design, an escape space is formed between the connecting portion and the abutting portion, and the escape space is located at an end of the tongue core close to the connecting portion.

In this solution, the setting of the avoidance space can ensure the effective connection between the cable plug and the tongue core, while avoiding contact between the cable plug and the connecting part, thereby preventing the connector from being affected by the insertion force of the cable plug and the connection with the circuit board from failing, thereby improving the connection stability between the connector and the circuit board.

In a possible design, the connecting channel includes a channel inner wall, and a first chamfered portion is provided at one end of the channel inner wall close to the mounting cavity.

In this solution, when installing the connector, space needs to be reserved in the installation cavity so that the connector can be inserted into the connecting channel at an angle in the installation cavity. The provision of the first chamfered portion can increase the opening of the connecting channel on one side of the installation cavity and has a guiding effect, thereby making it easier for the connector to be inserted into the connecting channel along the first chamfered portion, reducing the difficulty of installing the connector and reducing the installation space required for the connector in the axial direction in the installation cavity, thereby facilitating the miniaturization design of the electronic device.

In a possible design, the electronic device further includes a sealing member, and the sealing member is disposed between the connecting portion and an inner wall of the channel.

In the present solution, the sealing member is arranged between the connecting part and the inner wall of the channel to seal the fitting gap between the connecting part and the inner wall of the channel, thereby preventing water vapor from entering the installation cavity from the fitting gap between the connecting part and the inner wall of the channel, thereby improving the waterproof effect of the electronic equipment. The sealing member is arranged between the connecting part and the inner wall of the channel, and occupies a small space, and will not occupy additional space that is higher or wider than the connecting cavity in the radial direction, thereby realizing a small-size waterproof setting, which is beneficial to the overall lightweight design of the electronic equipment and meets the market demand.

In a possible design, the connecting portion is provided with a groove, the sealing member is arranged in the groove and cooperates with the inner wall of the channel.

In this solution, the seal is arranged on the connection part. Before the connector is assembled with the circuit board and the housing, the seal needs to be connected to the connection part, so that the electronic device can be waterproofed during the assembly process of the connector and the housing, which reduces the difficulty of installing the seal and improves the assembly efficiency of the whole machine. In addition, during the installation process, the seal and the tongue core will not interfere with each other, thereby improving the qualified yield rate of the electronic device. At the same time, the groove can increase the contact area between the seal and the connection part, thereby improving the connection strength between the seal and the connection part, and can limit the axial displacement of the seal on the connector, avoiding the seal from being squeezed and moved during the assembly process of the connector and the housing, thereby affecting the functions of other components on the connector, and further improving the structural stability and waterproof yield rate of the electronic device.

In a possible design, the sealing element is formed in the groove by injection molding.

In this solution, when the seal is injection molded in the groove of the connecting part, the connection strength between the seal and the connecting part is further increased. At the same time, the seal and the connector are integrated, so that the seal does not need to be installed on the connecting part by additional manual work, further improving the assembly efficiency of the electronic equipment.

In a possible design, the sealing element is clamped in the groove.

In this solution, the seal is clamped in the groove, which can realize a detachable connection between the seal and the connecting part, facilitates the replacement of the seal, is beneficial to the subsequent maintenance of the electronic device, reduces the user's maintenance cost, and improves the user's experience.

In a possible design, the sealing member includes a body and a protrusion, wherein the body is fixedly connected to the groove, and the protrusion is cooperatively connected to the inner wall of the channel.

In this solution, the structure can reduce the manufacturing material of the seal, saving costs, and the protrusion is easy to deform, thereby reducing the difficulty of installing the connector and the housing and improving the assembly efficiency of the electronic equipment.

In a possible design, the sealing element is annular.

In this solution, when the seal is annular, there is no need to consider the installation angle when manually installing the seal on the connection part, which reduces the difficulty of installation, facilitates disassembly and assembly, and improves disassembly and assembly efficiency. In addition, the annular seal is easy to produce and process, which is convenient for mass production and saves costs.

In a possible design, the sealing member is fixedly connected to the inner wall of the channel and is cooperatively connected to the connecting portion.

In this solution, when the seal is arranged on the inner wall of the channel, the connection part does not need to be provided with additional limiting or connecting structures related to the installation of the seal, which reduces the manufacturing difficulty of the connector. In addition, this structural design can achieve a wider distribution range of seals along the axial length on the inner wall of the channel, thereby further improving the waterproof yield.

The fixed end and the mounting portion are arranged correspondingly to ensure the effective connection between the fixed end and the mounting portion. The fixed end is located on both sides of the chip connecting end, which can reduce the axial length of the connector mounting cavity, reduce the volume of the connector, and further improve the space utilization of the mounting cavity, so that there can be enough space in the mounting cavity to install other components, so that the electronic device can realize more functions, and also improve the structural compactness of the electronic device, which is conducive to the miniaturized design of the electronic device and meets the market demand.

Detailed ways

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

In a specific embodiment, the present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

FIG1 shows a partial structure of an electronic device 10′ in the prior art, which is an I/O interface part formed by the housing 1′, the circuit board 2′ and the connector 3′. In order to facilitate the assembly of the whole machine, the connector 3′ is generally composed of a body 31′, a shell 32′ and a stopper 33′, and the connector cavity 34′ and the plug slot 13′ together constitute a connection cavity. When the cable plug 20 is inserted into the connection cavity and connected to the body 31′, the cable plug 20 will abut against the stopper 33′ of the connector 3′, and the insertion force will be directly transmitted to the welding point 6′ between the body 31′ and the circuit board 2′ through the stopper 33′, thereby causing damage and cracking at the welding point 6′, causing the signal of the connector 3′ to be disconnected, making it impossible for the electronic device to charge or transmit data, and the reliability is low.

In the prior art, most of the methods are to set some limiting components that can limit the connector 3' or the circuit board 2' in the installation cavity 11', so that the insertion force generated during the insertion of the cable plug 20 can be shared and absorbed by the limiting components, thereby reducing the force at the welding point 6', thereby ensuring the strength of the I/O interface in daily use or during the falling process. However, this design scheme has a relatively complex structure. On the one hand, in order to ensure the limiting effect of the limiting component on the connector 3' or the circuit board 2', the processing accuracy of the limiting component and its surrounding components is extremely high, which will increase additional costs. On the other hand, the limiting component will occupy the space in the installation cavity 11', which is not conducive to the thinning and miniaturization of the whole machine. For example, the limiting part 7' shown in Figure 1 can limit the connector 3' in the axial direction and absorb part of the insertion force, but it is necessary to reserve space between the casing 1' and the outer shell 32' to meet the arrangement and force requirements of the limiting part 7'.

In addition, in order to meet the user's demand for the integration of electronic devices, the inner wall of the connector cavity 34' is generally plated with color to make the inner wall of the connector cavity 34' consistent with the color of the plug-in slot 13', thereby improving the refinement of the connection cavity. However, this adds extra costs, and plugging and unplugging the cable plug 20 can easily cause the inner wall of the connector cavity 34' to wear and discolor, reducing the user experience.

In order to solve the above technical problems, the present application provides an electronic device, which includes terminal electronic devices such as mobile phones, tablet computers, personal digital assistants (PDAs), laptop computers, car computers, AR & VR devices, etc., which are not limited here. The present application is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

An embodiment of the present application provides an electronic device 10, as shown in Figures 2 to 5, including a shell 16 and a connector 3, the shell 16 is provided with an installation cavity 11, a connecting channel 12 and a connecting cavity 13 which are connected in sequence, on the shell 16, the connecting channel 12 includes a channel inner wall 121, the connecting cavity 13 includes a connecting inner wall 131, the connecting channel 12 is connected to the bottom of the connecting cavity 13, and the first contour and the second contour at least partially do not overlap, wherein the first contour is the contour of the channel inner wall 121 at the bottom, and the second contour is the contour of the connecting inner wall 131 at the bottom, the connector 3 is insert-molded, and at least a portion of the connector 3 can extend into the connecting cavity 13 through the connecting channel 12, wherein the portion of the bottom located between the first contour and the second contour is an abutment surface 141, and the abutment surface 141 is used to contact the cable plug 20 extending into the connecting cavity 13.

In this embodiment, as shown in FIGS. 2 to 5 , the cable plug 20 can be inserted into the connection cavity 13 and connected to the connector 3, so that the user can charge or transfer data to the electronic device 10. In the process of inserting the cable plug 20 into the connection cavity 13 along the connection inner wall 131, the abutment surface 141 can limit the cable plug 20 along the insertion direction of the cable plug 20, that is, when the cable plug 20 is connected to the connector 3 in place, the cable plug 20 can contact the abutment surface 141 to prevent the cable plug 20 from continuing to extend, and the insertion force generated by the cable plug 20 during the insertion process can be completely borne by the abutment surface 141, thereby preventing the connector 3 from being subjected to external forces and causing the connection with other components in the installation cavity 11 to fail, affecting the use function of the connector 3, ensuring the connection stability of the electronic device 10 during daily use or falling, and improving the electronic device 10. The reliability of the connection with the cable plug 20 improves the service life of the electronic device 10. At the same time, since there is no need to set an additional limiting component in the installation cavity 11 to limit the connector 3, the structural complexity and manufacturing difficulty of the electronic device 10 are reduced, the cost is saved, and the space in the installation cavity 11 is saved, which is conducive to the design of the electronic device 10 to be thinner and smaller. In addition, the connection cavity 13 is arranged in the shell 16, and the connecting inner wall 131 of the connection cavity 13 is made of the same material and color, and the connecting inner wall 131 will not be discolored due to wear during the plugging process of the cable plug 20, which improves the refinement of the interior of the connection cavity 13 and the integrity of the overall design. In addition, there is no need to perform additional color plating on the connecting inner wall 131, which further saves costs.

Among them, insert molding is also called insert injection molding. Insert molding refers to the process of pre-loading prepared metal terminals and other heterogeneous material parts into the mold as inserts, and then injecting plastic or resin and other materials into the mold, so that the molten material wraps the insert, and then solidifies and forms an integrated product. Due to the combination of the easy formability and bendability of the injection molding material and the rigidity, strength and heat resistance of the metal, complex and delicate metal-plastic integrated products can be firmly made. In particular, the combination of the insulation of the injection molding material and the conductivity of the metal is utilized, and the molded products can meet the basic functions of electronic products, and the pre-molding combination of multiple inserts makes the post-processing of the product unit combination more rational, and can also make the automation combination of the post-process easier. Because it is the bonding of molten material and metal inserts, compared with the press-in molding method, the gap between the metal inserts can be designed to be narrower, and the reliability of the composite product molding is higher. Among them, the insert products are not limited to metals, but also cloth, paper, wire, plastic, glass, wood, coils, electronic parts and many other types.

In the embodiment of the present application, the connector 3 is insert-molded, so that the connector 3 is an integrally molded structure, which can improve the reliability of the connector 3 and also make the connector 3 easier to realize automated production, thereby improving production efficiency.

In addition, the cable plug 20 may be a cable plug of an earphone, a charger, or a data transmission device, which is not limited here.

Among them, the housing 1 is a protective component wrapped around the outside of each component of the electronic device. The housing 1 includes a shell 16 and may also include an abutment portion 14. The abutment portion 14 is formed on the inner wall of the shell 16. The abutment portion 14 can be integrally formed with the shell 16, or the abutment portion 14 can be injection molded on the shell 16. The installation cavity 11 is a cavity formed inside the housing 1, which is used to provide installation space for various components of the electronic device. The connecting cavity 13 is formed at one end of the housing 1, which is an interface that enables the internal installation cavity 11 of the electronic device to communicate with the outside. The connecting inner wall 131 of the connecting cavity 13 cooperates with the cable plug 20 to limit the radial freedom of the cable plug 20, so as to improve the connection stability of the cable plug 20, and can protect the tongue core 32 of the connector 3 from damage by external forces. The connecting channel 12 is a channel formed on the housing 1 for connecting the installation cavity 11 and the connecting cavity 13. The inner wall 121 of the channel can also provide partial fixed support for the connector 3, thereby improving the fixing effect of the connector 3.

That is to say, the abutment portion 14 is located between the installation cavity 11 and the connecting cavity 13, the annular surface of the abutment portion 14 roughly parallel to the connecting inner wall 131 is the channel inner wall 121, and the annular surface of the abutment portion 14 roughly perpendicular to the connecting inner wall 131 on the side facing the connecting cavity 13 is the abutment surface 141.

As shown in Figures 4 to 6, the abutment surface 141 is flat and smooth, and the abutment surface 141 is roughly perpendicular to the link inner wall 131. When the cable plug 20 is connected to the connector 3, the abutment surface 141 abuts against the cable plug 20, which can effectively prevent the cable plug 20 from further extending and bear the insertion force of the cable plug 20, thereby preventing the connector 3 from being affected by the insertion force of the cable plug 20.

In a specific embodiment, as shown in FIG. 4 and FIG. 5 , the electronic device further includes a circuit board 2 , the circuit board 2 is installed in the installation cavity 11 , and the circuit board 2 is connected to the connector 3 .

In this embodiment, as shown in Figures 4 and 5, the connector 3 is connected to the circuit board 2 so that the connector 3 has charging and data transmission functions, which is convenient for users to charge or transmit data to electronic devices, thereby meeting people's daily use needs and improving the convenience of using electronic devices.

The connector 3 can be connected to the circuit board 2 by welding.

In a specific embodiment, the circuit board 2 can be a printed circuit board (PCB) or a flexible printed circuit (FPC) according to the space utilization or functional requirements of the electronic device, so as to improve the space utilization or functional performance of the electronic device to meet the various usage requirements of users. Of course, the circuit board 2 can also be other types of circuit boards, which are not limited here.

Those skilled in the art will appreciate that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 10. In other possible implementations of the present application, the electronic device 10 may include more components than shown in the figure, or combine certain components, or separate certain components, or arrange the components differently.

In a specific embodiment, as shown in FIG. 6 , the abutting surface 141 is formed on the side of the abutting portion 14 facing the connecting cavity 13 , the abutting portion 14 is formed between the channel inner wall 121 and the connecting inner wall 131 , and the abutting portion 14 is injection molded on the housing 16 .

In this embodiment, as shown in FIG. 6 , when the abutting portion 14 is formed on the shell 16 by injection molding, the connection strength between the abutting portion 14 and the shell 16 is high and it is not easy to separate from the shell 16, so that the insertion force when the cable plug 20 abuts against the abutting portion 14 can be transmitted to the shell 16, thereby improving the reliability of the abutting portion 14 and allowing the abutting portion 14 and the shell 16 to be made of different materials to meet the hardness or material requirements of different parts of the housing 1. Etc., saving manufacturing costs.

In addition, as shown in FIG. 2 , the housing 16 and the abutting portion 14 together form a casing 1 that wraps around the outside of the electronic device to provide protection for the components inside the electronic device.

Specifically, the shell 16 may be made of aluminum alloy, and the abutting portion 14 may be made of plastic.

In this embodiment, when the shell 16 is made of aluminum alloy, it has higher hardness and lighter weight, which makes the shell 1 more wear-resistant and drop-resistant, while reducing the weight of the whole machine, which is conducive to the lightweight design of the whole machine. In addition, the material of the abutment part 14 is plastic, which saves the manufacturing cost of the casing 1 and is not easy to deform, further improving the reliability of the abutment part 14.

Of course, the housing 16 may also be made of other metal materials, and the abutting portion 14 may also be made of other plastic materials, which are not limited here.

In another specific embodiment, as shown in FIG. 6 , the housing 16 and the abutting portion 14 are integrally formed.

In this embodiment, as shown in FIG. 6 , the shell 16 and the abutting portion 14 are integrally formed, with a simple structure, and are easy to manufacture. The connection strength between the abutting portion 14 and the shell 16 is improved, so as to further improve the reliability of the abutting portion 14 limiting the cable plug 20, and avoid the abutting portion 14 from being displaced toward the mounting cavity 11 during the insertion of the cable plug 20, thereby avoiding the connector 3 from being subjected to the axial insertion force of the cable plug 20, further improving the connection reliability between the electronic device 10 and the cable plug 20, and improving the service life of the electronic device 10.

When the shell 16 and the abutting portion 14 are integrally formed, the shell 16 and the abutting portion 14 are made of the same material, such as metal or plastic, which is not limited here.

In a specific embodiment, as shown in FIG. 6 , the abutment portion 14 is annular and is radially disposed at a position where the housing 16 is located in the connecting channel 12 .

In this embodiment, as shown in Figure 6, when the abutment portion 14 is annular, the area of the abutment surface 141 of the abutment portion 14 and the cable plug 20 can be increased, so that the abutment portion 14 can withstand a larger insertion force, and the force on the abutment portion 14 is more uniform, further avoiding damage to the abutment portion 14. When the abutment portion 14 is annular, the channel inner wall 121 in the connecting channel 12 is flat and has no protrusions, which can reduce the gap between the channel inner wall 121 and the connector 3, thereby facilitating waterproof settings.

In another specific embodiment, the abutting portions 14 are protrusions distributed at intervals at the position of the housing 16 located at the connecting channel 12 .

In this embodiment, when the abutting portions 14 are protrusions distributed at intervals, the use of manufacturing materials can be reduced, and the weight of the housing 1 can be reduced, thereby facilitating a more lightweight design of the entire electronic device 10 .

Of course, the abutting portion 14 may also be a combination of the above-mentioned ring shape and protrusion, or other structures, as long as it can limit the cable plug 20, and there is no limitation here.

In a specific embodiment, as shown in FIG. 4 and FIG. 6 , the connecting channel 12 includes a channel inner wall 121 , and a first chamfered portion 122 is provided at one end of the channel inner wall 121 close to the mounting cavity 11 .

In this embodiment, as shown in Figures 4 and 6, when the connector 3 is installed, space needs to be reserved in the installation cavity 11 so that the connector 3 can be obliquely inserted into the connecting channel 12 in the installation cavity 11, and the setting of the first chamfered portion 122 can increase the opening of the connecting channel 12 on one side of the installation cavity 11 and has a guiding effect, so that the connector 3 is easier to insert into the connecting channel 12 along the first chamfered portion 122, thereby reducing the installation difficulty of the connector 3 and reducing the installation space required for the connector 3 in the axial direction in the installation cavity 11, thereby facilitating the miniaturization design of the electronic device 10.

In a specific embodiment, as shown in FIG. 5 and FIG. 6 , the connecting cavity 13 includes a connecting inner wall 131 , and a second chamfered portion 132 is provided at one end of the connecting inner wall 131 away from the connecting channel 12 .

In this embodiment, as shown in Figures 5 and 6, the second chamfered portion 132 can connect the opening of the cavity 13 away from the connecting channel 12 and has a guiding function, thereby reducing the difficulty of inserting the cable plug 20, improving the connection efficiency between the cable plug 20 and the electronic device 10, and improving the user experience.

Of course, the first chamfered portion 122 and the second chamfered portion 132 may also be rounded with a smooth transition, which is not limited here.

In a specific embodiment, as shown in Figure 7, the connector 3 includes a connecting portion 31 and a tongue core 32, the connecting portion 31 is fixed in the connecting channel 12, the tongue core 32 is fixedly connected to the connecting portion 31 near the connecting cavity 13, and is at least partially located in the connecting cavity 13.

In this embodiment, as shown in FIG. 7 , the connecting portion 31 is fixed in the connecting channel 12, so that the tongue core 32 can be suspended in the connecting cavity 13, so as to facilitate the connection with the cable plug 20. Moreover, the fixing of the connecting portion 31 in the connecting channel 12 can improve the connection stability of the connector 3, limit the displacement of the connector 3 in the connecting channel 12, thereby ensuring that the position and extension amount of the tongue core 32 in the connecting cavity 13 remain unchanged, avoiding the failure of the connection between the cable plug 20 and the tongue core 32, thereby ensuring the effectiveness of the cable plug 20 inserted into the connecting cavity 13 to be able to cooperate with the tongue core 32 for connection, and improving the connection reliability between the electronic device 10 and the cable plug 20.

In a specific embodiment, as shown in FIG. 5 and FIG. 7 , the length of the tongue core 32 in the connecting cavity 13 is L, and 4.4 mm≤L≤4.5 mm. For example, the length L can be 4.44 mm, 4.45 mm, 4.46 mm, etc., which is not limited here.

In this embodiment, as shown in FIG. 5 and FIG. 7 , when the length L of the tongue core 32 in the connection cavity 13 does not satisfy 4.4 mm ≤ L ≤ 4.5 mm, the electronic device 10 cannot be compatible with the common cable plug 20 on the market, and the cable plug 20 needs to be customized, which increases the manufacturing cost and is inconvenient for the user's daily life, increasing the additional use cost. Among them, if the length L of the tongue core 32 in the connection cavity 13 is less than 4.4 mm, the extension of the tongue core 32 is short, and when the cable plug 20 abuts against the abutment portion 14, the cable plug 20 cannot fit in place with the tongue core 32, thereby affecting the charging or data transmission of the electronic device 10. If the length L of the tongue core 32 in the connecting cavity 13 is greater than 4.5 mm, the protrusion of the tongue core 32 is longer, so that during the insertion of the cable plug 20, the end of the tongue core 32 away from the connecting portion 31 will abut and interfere with the cable plug 20, so that the insertion force of the cable plug 20 is transmitted to the connection between the connector 3 and the circuit board 2 through the tongue core 32, causing the connection to crack and open, thereby affecting the charging or data transmission of the electronic device 10.

Therefore, when the length L of the tongue core 32 in the connecting cavity 13 is 4.4mm≤L≤4.5mm, the electronic device 10 can be matched with the common cable plug 20 on the market, thereby improving the applicability of the electronic device 10 in charging or data transmission, reducing costs, and making it convenient for users to connect the electronic device 10 with other terminals or devices, meeting the daily use needs of users, reducing use costs, and improving the user's use experience.

As shown in FIG. 5 , the size of the connecting cavity 13 may also match the size of a commercially available cable plug 20, so that the connecting cavity 13 can fully include the cable plug 20, thereby preventing the cable plug 20 from being offset during the insertion process, further ensuring the effectiveness of the cable plug 20 being inserted into the connecting cavity 13 and being able to cooperate with the tongue core 32 for connection, and improving the connection reliability between the electronic device 10 and the cable plug 20.

In a specific embodiment, as shown in FIG. 8 , the connecting portion 31 includes an end surface 311 facing a side of the connecting cavity 13 , and the end surface 311 is located in the connecting channel 12 .

In this embodiment, as shown in Figures 5 and 8, the connecting portion 31 is retracted into the connecting channel 12, which can avoid abutment interference with the cable plug 20 inserted into the connecting cavity 13, ensuring that the cable plug 20 can directly abut against the abutment portion 14 after being inserted into the connecting cavity 13. The abutment portion 14 bears the entire insertion force, thereby improving the protection of the connector 3, further ensuring the connection stability of the connector 3, and improving the connection reliability between the electronic device 10 and the cable plug 20.

In another specific embodiment, the connecting portion 31 may also have no end surface 311 , as shown in FIG. 8 , and an escape space 7 is formed between the connecting portion 31 and the abutting portion 14 , and the escape space 7 is located at one end of the tongue core 32 close to the connecting portion 31 .

In this embodiment, as shown in Figure 8, the setting of the avoidance space 7 can ensure that the cable plug 20 is effectively connected to the tongue core 32 while avoiding contact between the cable plug 20 and the connecting portion 31, thereby preventing the connector 3 from being affected by the insertion force of the cable plug 20 and causing the connection with the circuit board 2 to fail, thereby improving the connection stability between the connector 3 and the circuit board 2.

In a specific embodiment, as shown in Fig. 8, the distance between the end surface 311 and the abutting portion 14 or the height of the avoidance space 7 is d, 0.05mm≤d≤0.15mm. For example, d can be 0.08mm, 0.1mm, 0.12mm, etc., which is not limited here.

In this embodiment, as shown in FIG8 , if the distance between the end face 311 and the abutment portion 14 or the height d of the avoidance space is less than 0.05 mm, the distance between the end face 311 and the abutment portion 14 or the height d of the avoidance space 7 is too small. In order to ensure the limiting effect of the abutment portion 14, the processing accuracy of the abutment portion 14 is required to be high, which will increase the additional processing cost. If the distance between the end face 311 and the abutment portion 14 or the height d of the avoidance space 7 is greater than 0.05 mm, the distance between the end face 311 and the abutment portion 14 or the height d of the avoidance space is too large, which will increase the length of the connecting channel 12, thereby increasing the length of the housing 16, increasing the manufacturing materials of the housing 1, increasing the manufacturing cost, and being unfavorable to the miniaturization design of the electronic device 10.

Therefore, when the distance between the end face 311 and the abutment portion 14 or the height d of the avoidance space 7 satisfies 0.05mm≤d≤0.15mm, the limiting effect of the abutment portion 14 on the cable plug 20 can be ensured while the processing accuracy requirements of the abutment portion 14 are not high, and the structure of the electronic device 10 can be made more compact, saving costs, which is conducive to the miniaturized design of the electronic device 10 and meets market demand.

In order to improve the quality of electronic devices, existing electronic devices generally have waterproof performance to meet the needs of daily use of users. As shown in Figure 1, in the prior art, since the body 31' of the connector 3' is inserted into the shell 32', and the connector 3' is abutted against the housing 1' through the shell 32', the connection cavity formed by the connector cavity 34' and the plug slot 13' has a matching gap between the connector 3' and the body 31', and a matching gap between the shell 32' and the housing 1'. These two gaps are connected to the installation cavity 11'. Therefore, it is generally necessary to make two waterproofing at these two places to meet the waterproof requirements of the electronic device 10'. Among them, the prior art generally sets a first seal 4' between the shell 32' and the housing 1', reserves a space between the body 31' and the shell 32', and fills the second seal 5'. However, the first seal 4' is set outside the connection cavity, which will increase the radial size of the connector 3', which is not conducive to the thin and light design of the electronic device 10'. The second seal 5' is generally filled with glue. Due to the different thermal expansion coefficients of the second seal 5', the shell 32' and the body 31', when the connector 3' is welded to the circuit board 2', there is a problem that the second seal 5' cracks after the temperature of the connector 3' rises, resulting in waterproof failure. The waterproof yield is low and the usability is poor. It is often due to changes in the material and shape of the shell 32'. Reselecting the glue model requires a lot of time and cost to verify the process parameters.

In the electronic device 10 of the present application, there is only a fitting gap between the connecting portion 31 and the channel inner wall 121 of the connecting channel 12 that can communicate with the installation cavity 11, which reduces the path for water vapor to enter the installation cavity 11 from the connecting cavity 13. Therefore, only a waterproof layer needs to be made between the connecting portion 31 and the channel inner wall 121 to ensure the sealing of the installation cavity 11, which reduces the difficulty of waterproofing, improves the waterproofing yield, and saves costs.

In a specific embodiment, as shown in FIG. 4 , FIG. 9 and FIG. 10 , the electronic device 10 further includes a sealing member 4 , and the sealing member 4 is disposed between the connecting portion 31 and the inner wall 121 of the channel.

In this embodiment, as shown in Figures 4, 9 and 10, the seal 4 is arranged between the connecting portion 31 and the inner wall 121 of the channel to block the fitting gap between the connecting portion 31 and the inner wall 121 of the channel, and prevent water vapor from entering the installation cavity 11 from the fitting gap between the connecting portion 31 and the inner wall 121 of the channel, thereby improving the waterproof effect of the electronic device 10. The seal 4 is arranged between the connecting portion 31 and the inner wall 121 of the channel, occupies a small space, and does not occupy additional space that is higher or wider than the connecting cavity 13 in the radial direction. A small-size waterproof setting can be achieved, which is conducive to the lightweight design of the electronic device 10 and meets market demand.

The sealing member 4 may be disposed between the connecting portion 31 and the channel inner wall 121 in a variety of ways, such as being disposed on the channel inner wall 121 or on the connecting portion 31 , etc., which will be described below through specific embodiments.

In one embodiment, as shown in FIG. 9 and FIG. 10 , the connection portion 31 is provided with a groove 312 , and the sealing member 4 is disposed in the groove 312 and cooperates with the inner wall 121 of the channel.

In this embodiment, as shown in FIG9 and FIG10, the seal 4 is arranged on the connection part 31. Before the connector 3 is assembled with the circuit board 2 and the housing 1, the seal 4 needs to be connected to the connection part 31, so that the electronic device 10 can be waterproofed during the assembly process of the connector 3 and the housing 1, which reduces the installation difficulty of the seal 4 and improves the assembly efficiency of the whole machine. In addition, during the installation process, the seal 4 and the tongue core 32 will not interfere with each other, thereby improving the qualified yield of the electronic device 10. At the same time, the groove 312 can increase the contact area between the seal 4 and the connection part 31, thereby improving the connection strength between the seal 4 and the connection part 31, and can limit the axial displacement of the seal 4 on the connector 3, avoiding the seal 4 from being squeezed and moved during the assembly process of the connector 3 and the housing 1, thereby affecting the functions of other components on the connector 3, and further improving the structural stability and waterproof yield of the electronic device 10.

Specifically, as shown in FIG. 9 , the sealing member 4 may be formed in the groove 312 by injection molding.

In this embodiment, as shown in Figure 9, when the seal 4 is injection molded in the groove 312 of the connecting part 31, the connection strength between the seal 4 and the connecting part 31 is further increased. At the same time, the seal 4 is integrated with the connector 3, so that the seal 4 does not need to be installed on the connecting part 31 by additional manual operation, thereby further improving the assembly efficiency of the electronic device 10.

When the seal 4 can be formed in the groove 312 by injection molding, in a specific embodiment, as shown in FIG. 9 , the seal 4 can include a body 41 and a protrusion 42 , the body 41 is fixedly connected to the groove 312 , and the protrusion 42 is cooperatively connected to the inner wall 121 of the channel.

In this embodiment, as shown in FIG. 8 , the structure can reduce the manufacturing material of the seal 4 and save costs, and the protrusion 42 is easy to deform, thereby reducing the difficulty of installing the connector 3 and the housing 1 and improving the assembly efficiency of the electronic device 10 .

Of course, the sealing member 4 may also be formed in the groove 312 by injection molding in other shapes, such as a ring shape, etc., which is not limited here.

In another specific embodiment, as shown in FIG. 10 , the sealing member 4 may also be clamped in the groove 312 .

In this embodiment, as shown in FIG. 10 , the seal 4 is clamped in the groove 312 , which enables a detachable connection between the seal 4 and the connecting portion 31 , facilitates replacement of the seal 4 , is beneficial to subsequent maintenance of the electronic device 10 , reduces maintenance costs for users, and improves user experience.

When the sealing member 4 is engaged with the groove 312 , in a specific embodiment, as shown in FIG. 10 , the sealing member 4 may be annular.

In this embodiment, as shown in Figure 10, when the seal 4 is annular, there is no need to consider the installation angle when manually installing the seal 4 on the connecting portion 31, which reduces the difficulty of installation, facilitates disassembly and assembly, and improves disassembly and assembly efficiency. In addition, the annular seal 4 is easy to produce and process, which is convenient for mass production and saves costs.

Of course, the sealing member 4 may also be in other shapes, which is not limited here.

In another embodiment, the sealing member 4 may also be fixedly connected to the inner wall 121 of the channel and cooperatively connected to the connecting portion 31 .

In this embodiment, when the seal 4 is arranged on the inner wall 121 of the channel, the connection portion 31 does not need to be provided with any additional limiting or connecting structure for installing the seal 4, thereby reducing the manufacturing difficulty of the connector 3. In addition, this structural design can achieve a wider distribution range of the seal 4 along the axial length on the inner wall 121 of the channel, thereby further improving the waterproof yield.

The above-mentioned sealing members can all be made of flexible materials such as silicone, silicone rubber, rubber, etc. that are waterproof, elastic, high temperature resistant, and not easy to age, so as to improve the service life and waterproof performance of the sealing member 4.

It should be noted that, as shown in FIG9 and FIG10, the length of the connecting channel 12 is sufficient to accommodate the sealing member 4 while ensuring It is sufficient that the end surface 311 of the connecting portion 31 can be located in the connecting channel 12 , and no limitation is made here.

The chip connection terminal 331 and the circuit board 2 may be electrically connected by welding or other methods, which are not limited here.

The fixed end 332 is arranged corresponding to the mounting portion 15, which ensures the effective connection between the fixed end 332 and the mounting portion 15, and the fixed end 332 is located on both sides of the chip connecting end 331, which can reduce the axial length of the mounting cavity 11 of the connector 3, reduce the volume of the connector 3, and further improve the space utilization rate of the mounting cavity 11, so that there can be enough space in the mounting cavity 11 to install other components, so that the electronic device 10 can realize more functions, and also improve the compactness of the structure of the electronic device 10, which is conducive to the miniaturization design of the electronic device 10 and meets the market demand.

In a specific embodiment, as shown in Figures 4 and 11, the electronic device 10 also includes a fixing member 5, which is connected to the circuit board 2 and is surrounded to form a accommodating space. At least a portion of the chip connection end 331 is located in the accommodating space, and the chip connection end 331 is connected to the fixing member 5 on the side away from the circuit board 2.
