[0002] Electrical connectors are used for functions such as charging and data transmission of electronic devices. There are various ways to ground an electrical connector to ensure the safety of the electronic device. For example, the electrical connector of the Type-C interface has higher requirements for grounding due to its relatively high charging speed for electronic devices. In the prior art, adding a grounding point to the circuit board of the electrical connector and adding a grounding design to the circuit board of the electrical connector may bring a risk of relatively large fast charging impedance, thereby affecting the stability of the electrical connector. Summary of the Invention

Along the thickness direction of the electrical connector, the circuit board is stacked on the insulating body and covers part of the plug-in terminals, and the circuit board is connected and conducted with the plug-in terminals; along the thickness direction of the electrical connector, the circuit board is disposed opposite to the two insulating ear plates, the circuit board faces away from the conducting ear piece and is electrically conducted with the conducting ear piece; the electrical connector is installed in the electronic device, and the convex bump is connected and conducted with the grounding point of the main board.

[0005] In this embodiment, the electronic device is a mobile phone, its main board is a circuit board, a conducting ear piece made of a metal conductive material is embedded on the insulating body of the electrical connector, and a convex bump is provided on the conducting ear piece to conduct with the main board of the electronic device, and is grounded through the main board (a grounding point is provided between the main board and the middle frame); the grounding purpose of the electrical connector is achieved; and multiple convex bumps can be provided to achieve multi-point grounding, ensure the small impedance required for the electrical connector during fast charging (avoid generating too large impedance), and no grounding design is required for the circuit board, improving the utilization rate of the circuit board.

[0006] It can be understood that the greater the number of convex humps, the better the current grounding effect of the electrical connector, which greatly improves the charging speed of the electrical connector during fast charging, and also ensures the safety and stability of the operation of the electrical connector, bringing a good experience to users.

[0007] In one embodiment, the conductive component also includes a first pin, which is connected to one side of the conductive ear piece and is arranged at an angle to the conductive ear piece, and the first pin protrudes from the insulating ear plate with its back facing the conductive ear piece; the circuit board includes a first through hole, and the first through hole passes through two opposite surfaces of the circuit board in the thickness direction, and the circuit board also includes a connecting protrusion, which surrounds the periphery of the first through hole and is electrically connected to the circuit board, and the first pin passes through the first through hole and is fixed and conductive to the connecting protrusion.

[0008] In this embodiment, the first pin and the conductive ear piece are arranged at an angle, specifically, at a 90-degree angle, and the first pin does not occupy space in the width direction or length direction of the connector, saving the layout space of the electrical connector. In addition, the first pin is welded to the connecting protrusion, so that the current conduction between the circuit board and the conductive member is achieved, so that the current can be connected and conducted to the mainboard of the electronic device through the protrusion of the conductive ear piece.

[0009] In one embodiment, the conductive member is made of a metal conductive material, and the conductive member further includes a conductive bar, the two conductive ears are connected to two opposite ends of the conductive bar in the length direction, and the conductive bar is completely embedded in the insulating body.

[0010] In this embodiment, the conductive member and the insulating body are integrally injection molded, and a surface of the conductive strip facing away from the insulating body is evenly provided with a plurality of connection points for increasing the bonding strength between the conductive member and the insulating body and improving the bonding stability between the conductive strip and the insulating body.

[0012] In this embodiment, the protective shell is formed by stamping a metal material, such as a steel shell, which has high strength and high hardness, and can better protect and support the installation section of the insulating body, preventing the insertion terminals from being worn or damaged. At the same time, the protective shell made of metal material can also play an electromagnetic shielding role to avoid the influence of other external electronic devices on the signal transmission of the electrical connector, thereby improving the performance of the electrical connector.

[0013] In one embodiment, the electrical connector further includes a protective shell connected to the conducting member. The circuit board includes a second through hole and a welding protrusion.

At the same time, it can also be fixed to the electrical connector through the second pin. The protective shell is connected to the conducting member and the circuit board. After the electrical connector is installed in the electronic device, the protective shell can directly contact the middle frame of the electronic device and, together with the convex bump, serve as the grounding point of the electrical connector. The protective shell has a relatively large area, which can increase the grounding area of the electrical connector and improve the working stability of the electrical connector.

[0015] In one embodiment, an avoidance area is formed between the outer side edge of the insulating ear plate and the side edge of the circuit board for positioning the electrical connector and the electronic device.

[0016] In this embodiment, a limiting member is provided at a position corresponding to the avoidance area on the electronic device.

The main board is grounded through the middle frame. The electronic device is a mobile phone, its main board is a circuit board, a conductive earpiece made of metal conductive material is embedded on the insulating body of the electrical connector, and a convex bump is provided on the conductive earpiece to contact and electrically connect with the grounding point of the main board. The main board is grounded through the middle frame, thereby realizing the grounding purpose of the electrical connector. And by setting multiple convex bumps, multi-point grounding can be achieved to ensure the small impedance required by the electrical connector during fast charging (to avoid generating excessive impedance) and ensure the performance of the electronic device.

[0021] In one embodiment, the main board includes a first surface and a second surface, which are arranged back to back. The grounding point is provided on the first surface. The main board further includes a conductive gasket. One end of the conductive gasket is connected to the second surface and is conducted with the main board, and the other end of the conductive gasket is connected to the middle frame. In this embodiment, the main board and the middle frame are connected through the conductive gasket, with a simple structure that does not occupy too much space and does not require an additional complex grounding structure.

[0022] In one embodiment, the electronic device further includes a bracket. The main board, the electrical connector, and the bracket are installed on the middle frame. The bracket limits the electrical connector and the main board in the middle frame. An avoidance area is formed between the outer side of the insulating ear plate and the side of the circuit board. The bracket includes a limiting member, and the limiting member protrudes from the surface of the bracket and is clamped in the avoidance area.

[0023] In this embodiment, the avoidance area is used for the limiting member to limit the electrical connector in the length direction and the width direction. The distance from the outer side surface of the insulating ear plate facing away from the insulating body to the side surface of the circuit board in the width direction is L, and L is greater than or equal to 0.8 mm, so that the limiting member can better limit the electrical connector.

[0024] In one embodiment, the limiting member includes a first part and a second part connected to the first part. The first part and the second part have a certain distance from the surface of the bracket. Along the length direction of the electrical connector, the first part coincides with the insulating ear plate, and the height of the overlapping part of the first part and the insulating ear plate is the height of the first part. The range of the ratio of the height of the first part to the height of the insulating ear plate is 30%-100%.

[0027] In this embodiment, only two holes need to be provided for the fixation of the bracket, the electrical connector and the main board, and only two screws are needed, so that they can be locked and fixed to the middle frame; only two holes are needed for the bracket and the main board through the screws, so that the bracket and the main board are fixed to the middle frame, reducing the drilling area, thus saving the layout area of the main board and also saving the manufacturing cost. At the same time, the weight of the electronic device is also reduced, bringing a good experience to the user.

[0028] In one embodiment, the electronic device includes a middle frame, a main board, a conductive part and the electrical connector. The electrical connector is installed on the middle frame.

The present application does not impose special restrictions on the specific form of the electronic device 1000. In this embodiment, the electronic device 1000 is described by taking a folding mobile phone as an example.

At the same time, the folding mobile phone brings more interaction methods. The operation of a straight mobile phone mainly relies on the touch screen, while the folding mobile phone also supports handwriting input or gesture control in the folding area on this basis, improving the user experience and usage efficiency. At the same time, the folding mobile phone also requires a larger battery capacity and a faster charging speed.

[0057] For the sake of convenience of description, in this application, the width direction of the electronic device 1000 is defined as the X-axis direction, the length direction of the electronic device 1000 is defined as the Y-axis direction, and the thickness direction of the electronic device 1000 is defined as the Z-axis direction. Among them, the X-axis, Y-axis, and Z-axis directions are perpendicular to each other pairwise. It should be noted that the length direction of the electrical connector 10a is the same as the length direction of the electronic device 1000, the width direction of the electrical connector 10a is the same as the width direction of the electronic device 1000, and the height direction of the electrical connector 10a is opposite to the thickness direction of the electronic device 1000. The orientation terms such as "front", "rear", "top", "bottom", "left", and "right" mentioned in the description of the embodiments of this application are described based on the orientation shown in the attached drawings of the specification. Taking the direction towards the positive direction of the Z-axis as "top", the direction towards the negative direction of the Z-axis as "bottom", the direction towards the positive direction of the Y-axis as "front", the direction towards the negative direction of the Y-axis as "rear", the direction towards the positive direction of the X-axis as "right", and the direction towards the negative direction of the X-axis as "left", which does not form a limitation on the electrical connector 10a having a specific orientation, being constructed and operated in a specific orientation in the actual application scenario.

The battery (not shown in the figure), the bracket 80, the electrical connector 10a, the main board, and the display screen 90 are all installed in the housing. The processor, the electronic components, the display screen 90, and the battery are all electrically connected to the circuit board, and the processor and some small electronic components such as sensors are provided on the circuit board. In this embodiment, the housing includes a first part and a second part, and the first part and the second part are connected by a rotating shaft mechanism. The display screen 90 is a flexible display screen, such as an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, etc. The first part and the second part of the housing are relatively unfolded or folded through the rotating shaft mechanism. The display screen 90 is installed on the first part and the second part, and the first part and the second part rotate relative to each other through a rotating mechanism. When the first part and the second part approach each other relatively, the display screen 90 is driven to fold, so that the foldable electronic device 1000 folds. When the first part and the second part move away from each other relatively, the display screen 90 is driven to unfold, so that the foldable electronic device 1000 unfolds to a semi-unfolded state. It should be noted that the electronic device 1000 in this embodiment may be provided with two circuit boards, and the battery may be installed in the first part or the second part. The electrical connector 10a is provided in the first part or the second part. The electrical connector 10a in this embodiment may be an electrical connector of interface types such as Type-A, Type-B, and Type-C. In this embodiment, the electrical connector 10a is described by taking the Type-C interface as an example.

[0059] The electrical connector 10a is used for plugging with an external connector (male connector, such as a data cable), and can electrically connect the electronic device 1000 with other external electronic devices, such as a power cord, to charge the battery (not shown in the figure) in the electronic device 1000, and can also transmit signals with the electronic device 1000. Exemplarily, when other electronic devices are plugged with the electrical connector 10a of this electronic device 1000, at this time, the electrical connector 10a serves as a data transmission interface, such as picture transmission, file transmission, etc. When a power cord or other charging port is connected to the electronic device 1000, at this time, the electrical connector 10a serves as a charging interface for the battery (not shown in the figure).

In this embodiment, the number of grooves is three, the number of first through holes 83 is two, and the number of fifth positioning holes 84 is one. Along the thickness direction of the bracket 80, the first through hole 83 and the fifth positioning hole 84 both penetrate through the third surface 81 and the fourth surface 82, that is, both penetrate through the bottom wall of the several grooves and the fourth surface 82, and are both used for passing through screws. Along the X-axis direction, the two first through holes 83 are respectively located on opposite sides of the bracket 80. The fifth positioning hole 84 is located on one side of the bracket 80.

[0071] The bracket 80 further includes several limiting members 85. In this embodiment, the number of limiting members 85 is two.

The plug-in terminals 13 include several conductive sheets (not labeled in the figure), and the several conductive sheets extend along the length direction of the insulating body 11. Part of the plug-in terminals 13 is embedded in the insulating body 11. One end of the plug-in terminals 13 is located in the plug-in section 111 and exposes two surfaces in the thickness direction of the plug-in section 111. The plug-in terminals 13 and the plug-in section 111 form a plug-in end 131 of the electrical connector 10a; the plug-in end 131 is used for plugging and conducting with an external connector. The other end of the plug-in terminals 13 is located in the mounting section 113 and protrudes from one surface of the mounting section 113, which can be called a connection end 132. The connection end 132 is used for electrically connecting with the circuit board 2. The insulating body 11 is a plastic part, and the connection end 132 does not completely cover the plug-in terminals 13. It can be understood that the cooperation relationship between the plug-in terminals 13 and the insulating body 11 in this embodiment is the same as that of the terminals of the connector in the prior art.

[0077] In this embodiment, a receiving groove 14 is recessed on the surface of the connecting section 112 away from the plug-in terminals 13. The receiving groove 14 is used for receiving part of the conducting member 3. It should be noted that the conducting member 3 and the base 1 are integrally formed. The description of the receiving groove 14 here facilitates the subsequent understanding of the assembly relationship between the conducting member 3 and the base 1.

[0078] The insulating body 11 includes two insulating ear plates 12. The two insulating ear plates 12 protrude from opposite sides of the connecting section 112, and the two insulating ear plates 12 are arranged opposite to each other along the width direction of the insulating body 11. Specifically, the insulating ear plates 12 are plate-shaped, and the two insulating ear plates 12 in this embodiment are integrally formed with the insulating body 11. The insulating ear plates 12 are formed by extending from one side of the mounting section 113 along the length direction of the mounting section 113. Along the width direction of the insulating body 11, the two insulating ear plates 12 are located on opposite sides of the receiving groove 14. In fact, the insulating body 11 in this embodiment includes two insulating ear plates 12 with the same structure and size. The following description will be made taking one insulating ear plate 12 as an example.

[0079] The insulating ear plate 12 includes a front surface 121 and a back surface 122. Along the thickness direction of the insulating body 11, the front surface 121 and the back surface 122 are arranged facing away from each other. Each insulating ear plate 12 includes a groove 123. Along the thickness direction of the insulating body 11, the groove 123 is recessed from the front surface 121 towards the back surface 122. The groove 123 includes a circumferential side wall 1231 of the groove and a bottom wall 1232 of the groove. The circumferential side wall 1231 of the groove is convexly provided on the periphery of the bottom wall 1232 of the groove, and the circumferential side wall 1231 of the groove is connected to the surface of the mounting section 113. The insulating ear plate 12 further includes a first notch 124 and a second notch 125. The first notch 124 and the second notch 125 are spaced apart on the circumferential side wall 1231 of the groove. The first notch 124 penetrates through the circumferential side wall 1231 of the groove and communicates with the accommodating groove 14 for the passing of the conducting member 3. The second notch 125 penetrates through the circumferential side wall 1231 of the groove and faces the mounting section 113, which is used for cooperating with the conducting member 3.

[0080] Each insulating ear plate 12 further includes a second through hole 126, which penetrates through the bottom wall 1232 of the groove and the back surface 122 along the thickness direction of the insulating ear plate 12. The second through hole 126 is used for fixedly connecting the insulating ear plate 12 to the middle frame 60. The insulating ear plate 12 includes a convex ring 127. The convex ring 127 is convexly provided on the wall surface of the bottom wall 1232 of the groove. The convex ring 127 is arranged around the periphery of the second through hole 126. The insulating ear plate 12 further includes a protrusion 128. In this embodiment, the number of the protrusions 128 is two. Specifically, the protrusions 128 are convexly provided on the wall surface of the bottom wall 1232 of the groove. Along the Y-axis direction, the two protrusions 128 are completely staggered. Along the X-axis direction, the two protrusions 128 are completely staggered. The two protrusions 128 are located at a position of the insulating ear plate 12 close to the circumferential side wall 1231 of the groove, one protrusion 128 is adjacent to the first notch 124, and the other protrusion 128 is opposite to the first notch 124. In other embodiments, the number of the protrusions 128 may be one or more, and the present application does not make specific limitations here.

[0081] The circuit board 2 is generally a rectangular thin plate. The circuit board 2 includes a connection surface 21 and a mounting surface 22. Along the thickness direction of the circuit board 2, the connection surface 21 and the mounting surface 22 are arranged opposite to each other. The circuit board 2 includes several first through holes 23, several second through holes 24, several welding points 25, and several connection protrusions 26. Along the thickness direction of the circuit board 2, the several first through holes 23 and the several second through holes 24 penetrate through the connection surface 21 and the mounting surface 22. The several welding points 25 are arranged on the connection surface 21 of the circuit board 2. The welding points 25 are used for electrically connecting with one end of the mounting section 113 of the plug-in terminal 13 close to the insulating body 11; each welding point 25 is connected to a conductive sheet of the plug-in terminal 13 for current conduction between the circuit board 2 and the plug-in terminal 13. The number of the welding points 25 is determined according to the number of the conductive sheets of the plug-in terminal 13, and no specific limitation is made in this embodiment. Along the width direction of the circuit board 2, the several first through holes 23 are arranged on the opposite sides of the circuit board 2 for cooperation with the conducting member 3. The several second through holes 24 are arranged between the first through holes 23 and the several welding points 25 for cooperation with the protective case 4. In this embodiment, the number of both the first through holes 23 and the second through holes 24 is two.

[0082] The several connection protrusions 26 all protrude from the connection surface 21. In this embodiment, the number of the connection protrusions 26 is the same as that of the first through holes 23. The number of the connection protrusions 26 is two. The periphery of each first through hole 23 surrounds a connection protrusion 26. The connection protrusions 26 are used for welding with the conducting member 3 to achieve current conduction between the conducting member 3 and the circuit board 2.

[0083] The circuit board 2 can be a flexible printed circuit (FPC). In this embodiment, the adopted circuit board 2 can be a board body made of polyimide or polyester film as the base material. It has high reliability and excellent flexibility. The printed circuit board can be freely bent, wound, and folded, can be arranged arbitrarily according to the space layout requirements, and can move and stretch arbitrarily in three-dimensional space, which is very suitable for applications in smart foldable mobile phones or other electronic devices with high bending degree requirements. At the same time, the flexible printed circuit board is light in weight and thin in thickness, reducing the volume and weight of the electronic device 1000.

[0084] The conductive member 3 may be a generally strip-shaped sheet structure made of metal material. In this embodiment, the conductive member 3 may be made of copper. The conductive member 3 includes a plurality of conductive lugs 31, a conductive strip 32, and a plurality of bent portions 33. The bent portions 33 are connected to opposite sides of the conductive strip 32 and are connected to the conductive strip 32 at an angle. The conductive lug 31 is connected to the conductive strip 32 through the bent portions 33. The conductive lug 31 is connected to the conductive strip 32 at an angle. Exemplarily, the bent portions 33 are vertically connected to the conductive strip 32 and are vertically connected to the conductive lug 31. In this embodiment, the number of the conductive lugs 31 is two, and the number of the bent portions 33 is also two. The two conductive lugs 31 are located on opposite sides of the conductive strip 32, that is, the two conductive lugs 31 are arranged opposite to each other along the width direction of the conductive member 3. The conductive lugs 31 are sheet-shaped, and the two conductive lugs 31 of this embodiment are integrally formed with the conductive member 3. Each conductive ear piece 31 extends to a side away from the conductive strip 32 and extends perpendicular to the length direction of the bent portion 33. In fact, the conductive member 3 of this embodiment includes two conductive ear pieces 31 with the same structure and size. The following description takes one conductive ear piece 31 as an example.

[0085] The guide ear piece 31 includes an outer side wall 311, a fifth surface 312 and a sixth surface 313. The outer side wall 311 is arranged along the outer periphery of the guide ear piece 31 and is fixedly connected to the fifth surface 312 and the sixth surface 313. Along the thickness direction of the guide ear piece 31, the fifth surface 312 and the sixth surface 313 are arranged opposite to each other.

[0086] The conductive ear piece 31 further includes a third through hole 314. The third through hole 314 penetrates the fifth surface 312 and the sixth surface 313 along the thickness direction of the conductive ear piece 31, and is used to be sleeved on the outer periphery of the protruding ring 127 of the insulating ear plate 12.

[0087] The conductive ear piece 31 also includes a plurality of convex bumps 315 and a plurality of concave portions 316. In the present embodiment, the number of the convex bumps 315 and the concave portions 316 are both two. Specifically, two convex bumps 315 are convexly arranged on the sixth surface 313. Along the Y-axis direction, the two convex bumps 315 are completely staggered. Along the X-axis direction, the two convex bumps 315 are completely staggered. Two concave portions 316 are concavely arranged on the fifth surface 312. Along the Y-axis direction, the two concave portions 316 are staggered. Along the X-axis direction, the two concave portions 316 are staggered. The convex bumps 315 and the concave portions 316 correspond one to one. It can be explained that the convex bumps 315 are formed on the sixth surface 313 after being concavely arranged from the fifth surface 312 to the sixth surface 313. The grounding points 78 correspond one to one with the number of the convex bumps 315.

[0088] It should be noted that the number of the convex hulls 315 and the number of the concave portions 316 can both be two or more. The more the number of the convex hulls 315, the better the current grounding effect of the electrical connector 10a, so that when the electrical connector 10a is fast-charging, the charging speed is greatly improved, and the safety during charging is also ensured.

[0089] The conducting lug 31 includes a first pin 317. The first pin 317 is connected to the outer side wall 311 of the conducting lug 31, and the first pin 317 is connected to the conducting lug 31 at an angle. The first pin 317 is used for electrically connecting the conducting member 3 and the circuit board 2. Exemplarily, the first pin 317 bends and extends from one side of the conducting lug 31 in a direction away from the conducting lug 31. In fact, the first pin 317 is equivalent to a fifth surface 312 protruding from the conducting lug 31.

[0090] The conducting strip 32 includes a bottom surface 321 and a top surface 322. Along the thickness direction of the conducting member 3, the bottom surface 321 and the top surface 322 are arranged in opposite directions. The top surface 322 includes several connection points. The connection points are evenly distributed on the top surface 322, which is used to increase the bonding strength between the conducting member 3 and the insulating body 11, so as to ensure the improvement of the stability of the bonding between the top surface 322 of the conducting strip 32 and the bottom wall of the receiving groove 14 of the insulating body 11 during the injection molding process.

[0091] In this embodiment, the insulating body 11 and the conducting member 3 can be injection-molded. The two conducting lugs 31 of the conducting member 3 are respectively embedded in the grooves 123 of the two insulating ear plates 12 of the insulating body 11. The fifth surface 312 of the conducting lug 31 is connected to the bottom wall 1232 of the groove of the insulating ear plate 12, and the outer side wall 311 of the conducting lug 31 is connected to the peripheral side wall 1231 of the groove of the insulating ear plate 12. The third through hole 314 of the conducting lug 31 is coaxially and oppositely arranged with the second through hole 126 of the insulating ear plate 12 to form an ear portion A (not marked in the figure) for passing through the through hole of the screw. The third through hole 314 is sleeved on the outer periphery of the convex ring 127 of the insulating ear plate 12. The convex hulls 315, the concave portions 316 of the conducting lug 31 and the protrusions 128 of the insulating ear plate 12 correspond one by one. Specifically, the protrusion 128 correspondingly extends into the concave portion 316. The first pin 317 of the conducting member 3 passes through the first notch 124 and extends perpendicular to the insulating ear plate 12. It can be understood that the two conducting lugs 31 of the conducting member 3 and the two insulating ear plates 12 of the insulating body 11 correspond one by one to respectively form two ear portions A of the electrical connector 10a.

[0092] Such as Figure 8 and Figure 9, the protective housing 4 includes a first wall 41 and a second wall 42. The first wall 41 and the second wall 42 are connected at an angle. The protective housing 4 includes several second pins 43, several clamping feet 44, and several clamping holes 45. In this embodiment, the numbers of the second pins 43, the clamping feet 44, and the clamping holes 45 are all two. The second pins 43 are formed on both sides of the first wall 41 and the second wall 42, and are connected to the first wall 41 and the second wall 42 at an angle. The second pins 43 are used for welding and fixing to the circuit board 2. The clamping feet 44 are located on both sides of the first wall 41 and are spaced apart from the second pins 43. The length extension directions of the second pins 43 and the clamping feet 44 are the same. The clamping feet 44 protrude from the first wall 41 and are connected to the first wall 41 at an angle. The clamping holes 45 penetrate through the connection part of the first wall 41 and the second pins 43, and the clamping feet 44 are connected to the hole wall of the clamping hole 45 opposite to the second pins 43. Along the width direction of the protective housing 4, the clamping holes 45 are located between the second pins 43 and the clamping feet 44, and are used to cooperate with the clamping feet 44 to clamp the protective housing 4 to the connection end 132 of the insulating body 11.

[0093] The protective housing 4 further includes a receiving cavity 46 jointly formed by the second pins 43, the first wall 41, and the second wall 42. The receiving cavity 46 is used to receive the installation section 113 of the insulating body 11 and is used to cover and protect part of the connection end 132 of the electrical connector 10a. Along the width direction of the protective housing 4, the second pins 43 are located on opposite sides of the receiving cavity 46. In some embodiments, the second pins 43 are perpendicularly connected to both the first wall 41 and the second wall 42. The length and width of the second pins 43 are both greater than the length and width of the clamping feet 44.

[0094] In this embodiment, the protective housing 4 is formed by stamping a metal material, such as a steel shell, which has high strength and high hardness, and can better realize the protection and support functions for the connection end 132 of the insulating body 11, preventing the insertion terminals 13 from being worn or damaged. At the same time, the metal material protective housing 4 can also play an electromagnetic shielding role to avoid the influence of other external electronic devices on the signal transmission of the electrical connector 10a, thereby improving the performance of the electrical connector 10a.

[0095] Such as Figure 7, along the Z-axis direction, the circuit board 2 and the protective case 4 are respectively located on both sides of the connection end 132 of the electrical connector 10a, that is, the circuit board 2 and the protective case 4 are respectively located on the opposite sides of the installation section 113 of the insulating body 11. Along the width direction of the electrical connector 10a, the first pins 317 of the conducting member 3 and the second pins 43 of the protective case 4 are arranged in parallel and spaced apart, and the first pins 317 are located on both sides of the protective case 4. The first pins 317 pass through the first through holes 23 of the circuit board 2 and are welded to the connection protrusions 26 of the circuit board 2, thereby realizing the current conduction between the conducting member 3 and the circuit board 2. The second pins 43 pass through the second through holes 24 of the circuit board 2 to realize the fixation of the protective case 4 and the circuit board 2. The second pins 43 can also be omitted, that is, the protective case 4 can be directly fixedly connected to the insulating body 11 of the electrical connector 10a.

[0096] Please refer to Figure 11 , Figure 12 and Figure 13 , Figure 11 is Figure 2 a schematic diagram of the assembly structure of the conducting gasket of the electronic device shown in Figure 12 is Figure 2 a schematic diagram of the assembly process of the main board of the electronic device shown in Figure 13 is Figure 2 a schematic diagram of the assembly process of the electrical connector of the electronic device shown in

[0097] The conducting gasket 77 is installed on the surface of the middle plate 61 of the middle frame 60 and is adjacent to the fixing hole 66. Specifically, the conducting gasket 77 is connected to the middle plate 61. The main board 70 is installed on the middle frame 60, the second surface 72 of the main board 70 faces the surface of the middle plate 61, and the main board 70 is electrically connected to the conducting gasket 77, that is, the conducting gasket 77 is connected between the second surface 72 of the main board 70 and the middle frame 60, and is used to transmit the grounding current of the main board 70 to the middle frame 60, wherein the grounding point (not shown in the figure) on the second surface 72 of the main board 70 contacts and conducts with the conducting gasket 77. The protrusion 63 is located in the avoidance opening 73 of the main board 70. The fourth positioning hole 731 is sleeved on the outer periphery of the fixing hole 66. It can be understood that the conducting gasket 77 can also be directly arranged on the main board 70.

[0098] The first positioning body 601 of the middle frame 60 passes through the first positioning hole 74 of the main board 70. The second positioning body 602 of the middle frame 60 passes through the second positioning hole 75 of the main board 70, and the second positioning body 602 protrudes from the first surface 71 of the main board 70. The third positioning body 603 of the middle frame 60 passes through the third positioning hole 76 of the main board 70, so that the main board 70 is positioned on the middle frame 60. It should be noted that the second positioning body 602, the second positioning hole 75 and the fifth positioning hole 84 of the bracket 80 are coaxially arranged, and the surface of the second positioning body 602 facing away from the middle plate 61 abuts against the fourth surface 82 of the bracket 80.

[0099] Please refer to Figure 14 , Figure 15 and Figure 16 , Figure 14 which are Figure 2 schematic cross-sectional views of a partial structure of the electronic device shown in the figure taken along N-N, Figure 15 and Figure 2 schematic structural views of the limiting member and the electrical connector of the electronic device shown in the figure, Figure 16 and Figure 2 schematic cross-sectional views of a partial structure of the electronic device shown in the figure taken along B-B.

[0100] The insertion end 131 of the electrical connector 10a is inserted into the installation groove 64 of the middle frame 60 through the avoidance opening 73. The insertion end 131 of the electrical connector 10a is located in the installation groove 64 and faces the first notch 641. There is a gap between the insertion end 131 and the peripheral wall of the installation groove 64 for the external inserted docking connector to be inserted into the electrical connector 10a. A part of the insulating body 11 of the electrical connector 10a, that is, the connecting section 112, is partially located in the installation groove 64 and partially extends over the boss 643 into the receiving groove 65, and the installation section 113 is located in the receiving groove 65. The first wall 41 of the protective shell 4 abuts against the surface of the middle plate 61. The installation section 113 of the electrical connector 10a is located in the avoidance opening 73 and protrudes from the main board 70. The two ears A respectively extend out of both sides of the avoidance opening 73 and are stacked with the main board 70. Along the thickness direction of the electrical connector 10a, the back surface 122 (conductive member 3) of the insulating ear plate 12 of the ear A faces the connection surface 21 of the circuit board 2; the convex package 315 of the ear A abuts against the grounding point 78 on the first surface 71 of the main board 70; for realizing the conduction between the electrical connector 10a and the main board 70, and further electrically connecting the conductive ear piece 31 to the main board 70. The convex package 315 of this embodiment is conducted with the grounding point 78 for grounding the electrical connector 10a. The two ears A are clamped on the opposite sides in the width direction of the protrusion 63 of the middle frame 60. The through holes of the ears A are opposite and coaxially arranged with the fixing holes 66 of the middle frame 60 and the fourth positioning holes 731 of the main board 70. The circuit board 2 is located on the side of the electrical connector 10a away from the main board 70. The bracket 80 is installed on the middle plate 61 of the middle frame 60. The bracket 80, the main board 70 and the middle plate 61 are stacked. The main board 70 is clamped between the bracket 80 and the middle plate 61. The installation surface 22 of the circuit board 2 is spaced from the fourth surface 82 of the bracket 80.

[0101] Among them, the installation groove 64 can position the electrical connector 10a along the length direction of the electrical connector 10a. The boss 643 of the installation groove 64 surrounds the connection section 112 of the insulating body 11. A sealing ring 1121 is sleeved on the periphery of the connection section 112. The boss 643 is in close contact with the sealing ring 1121, which is used to seal the gap between the base 1 of the electrical connector 10a and the middle frame 60. At the same time, it can also be used to isolate the internal and external environments of the electronic device 1000, so as to realize the functions of external waterproofing and dustproofing of the electrical connector 10a.

[0102] The screw (not shown in the figure) sequentially passes through the fifth positioning hole 84 and the second positioning hole 75 and is fixed in the groove of the second positioning body 602, so as to fixedly connect the main board 70 and the bracket 80 to the middle frame 60, and fix the electrical connector 10a through the middle frame 60 and the bracket 80, ensuring the connection stability of the main board 70, the bracket 80 and the middle frame 60. At the same time, the screw sequentially passes through the first through hole 83 of the bracket 80, the second through hole 126 of the ear part A of the electrical connector 10a, the third through hole 314 and the fixing hole 66 of the middle frame 60, so as to fixedly attach the main board 70, the bracket 80 and the electrical connector 10a located between the main board 70 and the bracket 80 to the middle frame 60, ensuring the working stability of the electrical connector 10a and also ensuring a good grounding effect of the electrical connector 10a. It avoids the electrical connector 10a being easily shaken and causing safety accidents.

[0103] The two limiting members 85 are respectively located on the opposite sides of the circuit board 2 and at the edges of the two ear parts A (collectively referred to as an insulating ear plate 12 and a conducting ear piece 31) facing the circuit board 2, and the limiting members 85 abut against the opposite sides of the circuit board 2 and the two ear parts A, thereby limiting the electrical connector 10a in the X-axis, Y-axis and Z-axis directions.

[0104] It can be understood that only two holes need to be provided for the fixation of the three components of the bracket 80, the electrical connector 10a and the main board 70, and only two screws are needed to be locked and fixed to the middle frame 60; only two holes of the bracket 80 and the main board 70 need to pass through the screws, so that the bracket 80 and the main board 70 are fixed to the middle frame 60, reducing the drilling area, thus saving the layout area of the electronic device 1000 and also saving the manufacturing cost. At the same time, the volume and weight of the electronic device 1000 are also reduced, bringing a good experience to the user.

[0105] When the plugging end 131 of the electrical connector 10a is plugged into a docking connector in the outside world, the docking connector is electrically connected to the electrical connector 10a for signal transmission. At the same time, the plugging terminals 13 of the base 1 receive a grounding current, and the grounding current is conducted to the circuit board 2. Since the first through hole 23 of the circuit board 2 is welded to the first pin 317 of the conducting member 3, the electrical connection between the circuit board 2 and the conducting member 3 is realized, so that the grounding current on the circuit board 2 is conducted to the conducting member 3. Since the convex hull 315 of the conducting member 3 is electrically connected to the grounding point 78 on the first surface 71 of the main board 70, the grounding current of the conducting member 3 is conducted to the main board 70 through the convex hull 315. Since the second surface 72 of the main board 70 is connected and conducts the conducting gasket 77, and the conducting gasket 77 is connected to the surface of the middle board 61 and is electrically connected to the middle frame 60, the grounding current of the main board 70 is conducted to the middle frame 60 through the conducting gasket 77. The middle frame 60 receives the grounding current from the electrical connector 10a, thus realizing the grounding of the current of the electrical connector 10a. This method of multi-point grounding using a plurality of convex hulls 315 meets the small impedance required by the electrical connector 10a during fast charging, and does not require any design of the circuit board 2, only the requirement of grounding the current using the electrical connector 10a.

[0106] In this embodiment, the first pin 317 of the conducting member 3 passes through and is perpendicular to the circuit board 2, ensuring that the X axis direction can be used for the bracket 80 to perform limit, avoiding the bracket 80 being unable to perform limit in the X direction due to the horizontal placement of the first pin 317.

[0107] The distance from the outer side surface of the insulating ear plate 12 facing away from the insulating body 11 to the side surface in the width direction of the circuit board 2 is L. The circuit board 2 protrudes from the insulating ear plate 12 compared with the insulating ear plate 12. That is to say, the side of the circuit board 2 and the outer side of the insulating ear plate 12 are arranged in an L shape, and an avoidance area is formed. The limiting member 85 of the bracket 80 is located in the avoidance area to perform limit on the electrical connector 10a in the X-axis direction and the Y-axis direction. In this embodiment, L is greater than or equal to 0.8 mm, so that the limiting member 85 can better limit the electrical connector 10a.

[0108] Along the Z-axis direction, the second part 853 of the limiting member 85 of the bracket 80 is spaced from the first surface 71 of the main board 70. The surface of the second part 853 close to the insulating ear plate 12 can be an inclined surface, and the second part 853 is spaced from the insulating ear plate 12. The first part 852 is rectangular, and the connection surface of the first part 852 and the limiting body 851 facing away from the electrical connector 10a is a stepped surface. Along the width direction of the limiting member 85, the height w1 of the overlapping area between the insulating ear plate 12 and the first part 852 is the height of the first part 852, where w1 is greater than or equal to 0.4 mm. The height w2 of the insulating ear plate 12 is the distance between the back surface 122 of the insulating ear plate 12 and the first surface 71 of the main board 70, where w2 is greater than or equal to 0.7 mm. It should be noted that, in order to ensure good abutment and limitation of the electrical connector 10a, the ratio of the overlapping height w1 to the height w2 of the insulating ear plate 12 should satisfy 30%-100%, thereby ensuring the working stability and safety of the electrical connector 10a.

[0109] Please refer to Figure 17 , Figure 17 which is a schematic structural diagram of the electrical connector provided by the second embodiment of the present application.

[0110] The second embodiment of the present application provides an electrical connector 10b for an electronic device 1000, which can be an electrical connector of interface types such as Type-A, Type-B, and Type-C. In this embodiment, the electrical connector 10b is described by taking the Type-C interface as an example. The electrical connector 10b is used to connect and conduct with an external connector, so as to charge the electronic device 1000 and can also transmit signals for the electronic device 1000.

[0111] It should be noted that, compared with the electrical connector 10a of the first embodiment, the electrical connector 10b provided by the second embodiment of the present application has a different current grounding method. Specifically, the electrical connector 10b of the second embodiment can conduct the current to the ground through the protective shell 4.

[0112] Please refer to Figures 18 to 21 , Figure 18 which is Figure 17 a schematic exploded structural diagram of the electrical connector shown, Figure 19 which is Figure 17 a schematic structural diagram of a partial structure of the electrical connector shown, Figure 20 which is Figure 17 a schematic structural diagram of a partial structure of the electrical connector shown, Figure 21 which is Figure 17 a schematic cross-sectional view of the electrical connector shown taken along R-R.

[0113] The electrical connector 10b includes a base 1, a circuit board 2, a conducting member 3, and a protective housing 4. Among them, the conducting member 3 and the protective housing 4 are connected and installed on the base 1. The circuit board 2 is installed at one end of the base 1, and the circuit board 2 and the protective housing 4 are located on opposite sides of the base 1. The base 1 includes an insulating body 11 and plug-in terminals 13. The insulating body 11 includes a plug-in section 111, a connection section 112, and an installation section 113. One end of the plug-in terminal 13 is located in the plug-in section 111, and the plug-in terminal 13 and the plug-in section 111 form a plug-in end 131 of the electrical connector 10a; the other end of the plug-in terminal 13 is located in the installation section 113 and protrudes from the installation section 113, which is called a connection end 132.

[0114] In this embodiment, only the structure of the insulating body 11 in the base 1 is different from that of the first embodiment. The difference lies in that the groove side wall of the accommodating groove 14 of the insulating body 11 has an opening 141. The opening 141 penetrates through the groove side wall of the accommodating groove 14 and communicates with the accommodating groove 14. The opening 141 is used for passing through the connection part of the conducting member 3 and the protective housing 4. In this embodiment, the conducting member 3 and the protective housing 4 can be integrally formed, and the protective housing 4 and the conducting member 3 can be integrally formed with the base 1 by injection molding. The circuit board 2 is electrically connected to the plug-in terminal 13 of the base 1.

[0115] In this embodiment, the difference in the structure of the circuit board 2 from that of the first embodiment is that a plurality of welding protrusions 27 are arranged around the outer periphery of the second through hole 24. The welding protrusions 27 are used for welding and conducting with the protective housing 4 (different from the first embodiment). Specifically, the circuit board 2 includes a connection surface 21 and an installation surface 22. Along the thickness direction of the circuit board 2, the connection surface 21 and the installation surface 22 are arranged opposite to each other. The circuit board 2 includes several second through holes 24, several welding points 25, and several welding protrusions 27. Along the thickness direction of the circuit board 2, several second through holes 24 penetrate through the connection surface 21 and the installation surface 22. Several welding points 25 and several welding protrusions 27 are located on the connection surface 21. Several welding points 25 are connected and conduct with the plug-in terminal 13. The number of the welding protrusions 27 is the same as that of the second through holes 24. The welding protrusions 27 are connected and conduct with the circuit board 2. Each welding protrusion 27 is arranged around the periphery of a second through hole 24 for welding with the protective housing 4, so as to realize the current conduction between the protective housing 4 and the circuit board 2. In this embodiment, the number of both the second through holes 24 and the welding protrusions 27 is two.

[0116] The conducting member 3 includes several conducting lugs 31, a conducting strip 32, several bending portions 33, and a connecting strip 34. The conducting lug 31 includes multiple convex protrusions 315. Among them, in this embodiment, only the structures and connection relationships of the conducting strip 32 and the bending portion 33 of the conducting member 3 are the same as those in the first embodiment. One difference is that the connecting strip 34 is connected to the conducting strip 32. Specifically, the connecting strip 34 extends from one side of the conducting strip 32 in a direction away from the conducting strip 32. The connecting strip 34 is generally in a strip-like structure. For the convenience of connecting the conducting member 3 and the protective shell 4, the cross-section of the connecting strip 34 is arc-shaped. Another difference is that the conducting lug 31 does not include a first pin, and the first pin does not need to be welded to the circuit board 2, which can save the welding process of the conducting member 3 and the circuit board 2.

[0117] In this embodiment, the structure of the protective shell 4 is different from that of the first embodiment in that the second pin 43 of the protective shell 4 is used for electrical connection with the circuit board 2. Specifically, the protective shell 4 includes a first wall 41 and a second wall 42. The first wall 41 and the second wall 42 are connected at an angle. The protective shell 4 includes two second pins 43, two clamping feet 44, and two clamping holes 45. The clamping feet 44 and the clamping holes 45 cooperate to clamp and fix the protective shell 4 to the connection end 132 of the electrical connector 10b. The second pin 43 is used to weld and fix the protective shell 4 to the circuit board 2. Specifically, the second pin 43 passes through the second through hole 24 of the circuit board 2 and is connected and conducted with the welding protrusion 27. It can be understood that the protective shell 4 and the circuit board 2 are electrically conducted. In this embodiment, the protective shell 4 is made of a metal material, such as a steel shell.

[0118] In this embodiment, the electrical connector 10b is installed on the body portion 100 in the same way as the electrical connector 10a in the first embodiment. In this embodiment, a conductive portion (not shown in the figure) is provided between the electrical connector 10b and the middle frame 60. The conductive portion can be a spring piece or conductive glue. The spring piece or conductive glue is located on the surface of the first wall 41 of the protective shell 4 and the middle frame 60. At the same time, the conducting member 3 of the electrical connector 10b is connected and conducted with the protective shell 4 through the connecting strip 34. The groove side wall of the accommodating groove 14 of the insulating body 11 has an opening 141, and the connecting strip 34 passes through the opening 141 to realize the fixation of the conducting member 3 and the protective shell 4 to the insulating body 11.

[0119] In a possible implementation, when the electrical connector 10b is plugged into the docking connector, the docking connector is electrically connected to the electrical connector 10b for signal transmission. At the same time, the plugging terminal 13 of the base 1 receives the ground current. Since the connecting protrusion 26 of the second through hole 24 of the circuit board 2 is welded to the second pin 43 of the protective shell 4, the electrical connection between the circuit board 2 and the protective shell 4 is realized, so that the ground current on the circuit board 2 is conducted to the protective shell 4. Since the protective shell 4 is connected and conducted to the middle frame 60 (not shown in the figure) through the conductive part, the current is conducted to the middle frame 60 through the conductive part, and the middle frame 60 receives the ground current from the electrical connector 10b, thereby realizing the large-area current grounding of the electrical connector 10b.

[0120] It should be noted that, on the basis of this embodiment, since the conducting part 3 and the protective shell 4 are connected and conducted through the connecting strip 34, the current of the protective shell 4 is conducted to the conducting part 3 through the connecting strip 34. The current passing through the conducting part 3 can also be conducted to the main board 70 (not shown in the figure) through the plurality of convex hulls 315 of the conducting lug 31, and then conducted to the middle frame 60 through the conducting gasket 77 (not shown in the figure) connected and conducted to the main board 70, thereby realizing the current grounding implemented in parallel in multiple ways.

[0121] The structural design of the electrical connector 10b in this embodiment is simple. The grounding method of the electrical connector 10b can be selected according to needs, either grounding through the conductive part of the protective shell 4 or grounding through the convex hull 315, so that the grounding method of the electrical connector 10b is diversified, and it also meets the small impedance required by the electrical connector 10b during fast charging. Moreover, no design is required for the circuit board 2, only the requirement for the electrical connector 10b to have large-area current grounding is needed, which also ensures the safety and stability of the operation of the electrical connector 10b and brings a good experience to users.

[0122] The above are only some embodiments and implementation manners of the present application. The protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
