Description

Technical Field

[0001] The present application relates to the field of electronic devices, and more particularly, to an electrical connector, a circuit assembly and an electronic device. Background Art

[0002] Multiple electronic components and multiple circuit boards are usually arranged in electronic devices, wherein the electronic components can be electrically connected to the circuit boards to realize various functions. A common electrical connection method is that an electrical connector is fixed on the circuit board, and the electrical connector abuts against the electronic components arranged around the circuit board, so that the electronic components arranged around the circuit board can be electrically connected to the circuit board. Since electronic devices tend to be flat in appearance, the space used to electrically connect the electronic components and the circuit boards is limited. If the electrical connector is not designed reasonably, it is easy to cause insufficient space for electrically connecting the electronic components and the circuit boards, and even fail to meet the flattening requirements of the electronic equipment. Summary of the invention

[0003] The present application provides an electrical connector, a circuit assembly and an electronic device, the purpose of which is to reduce the space occupied by the electrical connector, thereby facilitating the flattening of the electronic device.

[0004] In a first aspect, an electrical connector is provided, comprising: a first limiting surface and a second limiting surface arranged in parallel, and a bearing surface connected between the first limiting surface and the second limiting surface, the bearing surface being arranged perpendicularly relative to the first limiting surface and the second limiting surface, and the first limiting surface, the second limiting surface and the bearing surface forming a cavity; the electrical connector also comprises a first extension arm partially located in the cavity and partially located outside the cavity, one end of the first extension arm is connected to the bearing surface, and the other end extends out of the cavity; one end of the first extension arm away from the bearing surface comprises an abutment area, the abutment area is located outside the cavity and is used to abut on a frame of an electronic device, and the abutment torque of the frame acting on the abutment area is perpendicular to the circuit board; the electrical connector also comprises one or more components for contacting the circuit board, at least one of the one or more components is used to electrically connect to the circuit board, and the one or more components comprise: a first supporting surface for being arranged on one side of the circuit board, the first supporting surface is connected to the first limiting surface or the second limiting surface, and the plane where the first supporting surface is located is located between the first limiting surface and the second limiting surface.

[0005] The first limiting surface and the second limiting surface may be planes or curved surfaces. The first limiting surface and the second limiting surface being arranged in parallel may mean that any plane of the first limiting surface perpendicular to the thickness direction is parallel to any plane of the second limiting surface perpendicular to the thickness direction.

[0006] The bearing surface may be a curved surface. The first limiting surface being perpendicular to the bearing surface may mean that any plane of the first limiting surface perpendicular to the thickness direction is perpendicular to any plane of the bearing surface perpendicular to the thickness direction. Similarly, the second limiting surface being perpendicular to the bearing surface may mean that any plane of the second limiting surface perpendicular to the thickness direction is perpendicular to any plane of the bearing surface perpendicular to the thickness direction.

[0007] The electronic device comprises a housing and a display screen. The housing comprises a back cover and a side frame, the side frame surrounds the periphery of the display screen and the periphery of the back cover, the back cover and the display screen are arranged in parallel and spaced apart, and the back cover and the display screen are respectively located on both sides of the side frame.

[0008] In one example, the side frame and the back cover are two parts of the housing, the side frame is connected to the back cover, and the connection between the side frame and the back cover is usually inseparable. The frame used for abutting the abutting area can be the side frame.

[0009] In one example, the electronic device includes a middle frame, and the periphery of the middle frame (hereinafter referred to as the periphery of the middle frame) can serve as a side frame of the electronic device. The back cover and the middle frame are two different components, and the housing of the electronic device can be formed by assembling the back cover and the middle frame together. The frame used for abutting the abutment area can be the periphery of the middle frame.

[0010] In one example, the side frame and the back cover are two parts of the housing, the side frame is connected to the back cover, and the connection between the side frame and the back cover is usually inseparable. The electronic device also includes a middle frame, which is accommodated in a cavity between the display screen, the side frame and the back cover. The frame used for abutment in the abutment area can be the periphery of the middle frame.

[0011] It should be noted that “component A is connected to component B” includes that component A and component B are connected together without any other component between component A and component B, and may also mean that component A and component B are connected together through component C.

[0012] It should be noted that "component 1 abuts against component 2" usually means that component 1 is in contact with component 2; and at least one of the following conditions is met: Condition 1: the area of ​​the contact surface is greater than the first preset threshold; Condition 2: within the maximum contour range of the contact surface, the number of non-contact points is less than the second preset threshold; Condition 3: within the maximum contour range of the contact surface, the area of ​​the non-contact surface is less than the third preset threshold.

[0013] The abutting area may be in the shape of a convex hull, such as a parabolic convex hull, an ellipsoidal convex hull, or a spherical convex hull. The abutting area may also not include a convex hull.

[0014] In the present application, the limiting surface, the supporting surface, and the connecting surface are all surface bodies. The plane where the surface body is located can be any plane within the thickness range of the surface body and perpendicular to the thickness direction.

[0015] The contact relationship between the first supporting surface and the circuit board includes movable contact and immovable contact (ie fixed).

[0016] In an embodiment of the present application, the first support surface between the first limiting surface and the second limiting surface is used to contact the circuit board, so the first limiting surface can be buried in the groove in the circuit board. In addition, the closer the bearing surface is to the frame of the electronic device, the closer the distance between the abutment area and the bearing surface is. Even if the distance between the frame of the electronic device and the bearing surface changes, the torque of the contact force between the abutment area and the frame of the electronic device on the first support surface will not change too much, so the matching accuracy of the electrical connector and the frame of the electronic device can be relaxed, and then the electrical connector can adapt to more assembly scenarios.

[0017] In combination with the first aspect, in some implementations of the first aspect, the first supporting surface is used to be fixed on the circuit board.

[0018] In the embodiment of the present application, the electrical connector can be fixed on the circuit board through the first supporting surface, so that it is easier to ensure that the electrical connector is firmly fixed on the circuit board.

[0019] In combination with the first aspect, in some implementations of the first aspect, the electrical connector further includes: a second extension arm connected to the abutment area, and an end of the second extension arm away from the abutment area is used to abut on the bearing surface.

[0020] In order to facilitate the division of the first extension arm and the second extension arm, the present application considers that the abutting area is the portion of the first extension arm located outside the cavity, and the second extension arm is located inside the cavity.

[0021] When the electrical connector is installed inside the electronic device, the end of the second extension arm away from the abutment area abuts against the bearing surface. When the electrical connector is not installed inside the electronic device, the end of the second extension arm away from the abutment area may or may not contact the bearing surface.

[0022] When the electrical connector is not installed inside the electronic device, the second extension arm does not contact the supporting surface, which can ensure that the surface of the second extension arm is completely electroplated with a thin film.

[0023] In the embodiment of the present application, the current can pass through the first extension arm and the second extension arm, so the electrical connector can transmit a higher current under the same voltage. In addition, the second extension arm can abut against the supporting surface, so the abutting area can withstand a higher contact force, and the electrical connector is less likely to produce arcing and is more likely to be in a stable working state.

[0024] In combination with the first aspect, in some implementations of the first aspect, the electrical connector further includes: a first hanging ear extending into the first hole on the first limiting surface.

[0025] Therefore, the movable space of the first hanging ear is limited by the contour of the first hole.

[0026] The first hanging ear may be arranged on the first extension arm, the abutment area or the second extension arm.

[0027] In the embodiment of the present application, the movable space of the first hanging ear is constrained by the first hole, so that the abutting area does not excessively extend out of the cavity formed by the first limiting surface, the second limiting surface and the supporting surface. During the transportation and installation of the electrical connector, it is helpful to prevent the first extension arm from excessively bending in a direction away from the supporting surface, thereby reducing the possibility of damage to the electrical connector.

[0028] In combination with the first aspect, in some implementations of the first aspect, the first hanging ear is used to abut against the contour of the first hole.

[0029] In the embodiment of the present application, the first hanging ear abuts against the contour of the first hole, so the first hanging ear can bear a part of the contact force generated by the abutting area abutting against the frame of the electronic component, which is conducive to the balanced force of the electrical connector. The first hanging ear can also play the role of electrical connection.

[0030] Optionally, the electrical connector further includes a second hanging ear, the second hanging ear extends into the second hole on the second limiting surface, and the second hanging ear is used to abut against the contour of the second hole.

[0031] In the embodiment of the present application, the force exerted by the first hanging ear on the first hole can generate torque 1 on the portion of the first supporting surface that contacts the circuit board, and the force exerted by the second hanging ear on the second hole can generate torque 2 on the portion of the second supporting surface 1614 that contacts the circuit board. Moment 1 and moment 2 can approximately offset each other, thereby reducing the possibility of tilting of the supporting surface.

[0032] In combination with the first aspect, in certain implementations of the first aspect, the electrical connector also includes: a first limiting ear connected to a side of the first limiting surface away from the supporting surface, and an end of the first limiting ear away from the first limiting surface extends toward the second limiting surface; the electrical connector also includes: a third extension arm connected to the abutment area, an end of the third extension arm away from the abutment area is located between the supporting surface and the first limiting ear, and a projection area of ​​the third extension arm on the supporting surface partially overlaps with a projection area of ​​the first limiting ear on the supporting surface.

[0033] In the embodiment of the present application, since the movable space of the third extension arm is constrained by the first limiting ear, the abutment area will not excessively extend out of the cavity formed by the first limiting surface, the second limiting surface and the bearing surface. During the transportation and installation of the electrical connector, it is helpful to prevent the first extension arm from excessively bending in the direction away from the bearing surface. In addition, the first limiting ear can strengthen the constraint of the movable space of the third extension arm in the cavity formed by the first limiting surface, the second limiting surface and the bearing surface. Therefore, the electrical connector is less likely to be damaged during transportation and installation.

[0034] In combination with the first aspect, in certain implementations of the first aspect, the first supporting surface is connected to the first limiting surface, and the one or more components also include: a first fixed end portion, connected to an end of the first supporting surface away from the first limiting surface, for being inserted into and fixed in the insertion hole of the circuit board.

[0035] In the embodiment of the present application, in view of the contact force between the abutting area and the frame of the electronic device, the bearing surface has a tendency to tilt and deform due to the contact force. By fixing the first fixed end to the circuit board, the first limiting surface can be constrained from moving, thereby preventing the bearing surface from tilting. The electrical connector includes the first fixed end, so there are more ways to fix the electrical connector, the flexibility is relatively high, and it is easier to ensure the stability of the installed circuit assembly.

[0036] In combination with the first aspect, in certain implementations of the first aspect, the first supporting surface is connected to the first limiting surface; the one or more components also include: a third fixed end portion, connected to an end of the second limiting surface close to the first supporting surface, for being inserted into and fixed in the insertion hole of the circuit board.

[0037] In the embodiment of the present application, in view of the contact force between the abutting area and the frame of the electronic device, the bearing surface has a tendency to tilt and deform due to the contact force. By fixing the third fixed end to the circuit board, the second limiting surface can be constrained from moving, thereby preventing the bearing surface from tilting. In addition, by extending the third fixed end into the circuit board and fixing it, a firm fixing effect can be achieved.

[0038] In combination with the first aspect, in some implementations of the first aspect, the electrical connector further includes: a first connecting surface, connected between the third fixed end and the second limiting surface, and located between the first supporting surface and the second limiting surface.

[0039] In the embodiment of the present application, since the first connection surface is located between the first supporting surface and the second limiting surface, the space occupied by the electrical connector can be reduced, which is conducive to improving the flatness of the electronic device and improving the compactness of the assembly of components inside the electronic device. In addition, the first connection surface is located between the first supporting surface and the second limiting surface, which is conducive to improving the structural symmetry of the electrical connector, and further, the mechanical stability of the electrical connector can be improved.

[0040] In combination with the first aspect, in some implementations of the first aspect, the first connecting surface is fixed on the first supporting surface.

[0041] In the embodiment of the present application, the first connection surface is fixed on the first support surface. On the one hand, the relative displacement between the first limit surface and the second limit surface can be constrained to prevent the bearing surface from tilting. On the other hand, since the first connection surface is fixed on the first support surface, the first connection surface and the first support surface can be electrically connected or insulated, thereby obtaining a variety of ways for current to flow through the electrical connector.

[0042] In combination with the first aspect, in some implementations of the first aspect, the first connection surface is used to be electrically connected to the first supporting surface.

[0043] In the embodiment of the present application, the first connection surface is electrically connected to the first supporting surface, so that the resistance difference flowing through the first fixed end and the third fixed end can be ignored, thereby improving the electrical connection stability of the electrical connector.

[0044] In combination with the first aspect, in certain implementations of the first aspect, the first supporting surface is connected to the second limiting surface, and the electrical connector further includes: a third supporting surface, fixed to a side of the first supporting surface close to the second limiting surface and connected to the first limiting surface.

[0045] In the embodiment of the present application, since the second limiting surface is fixed to the circuit board through the first supporting surface, and the first limiting surface is fixed to the circuit board through the third supporting surface and the first supporting surface, it is not necessary to additionally process the insertion hole for fixing the electrical connector on the circuit board, thereby saving the space occupied by the electrical connector on the circuit board.

[0046] Optionally, the first supporting surface is used to be electrically connected to the third supporting surface.

[0047] In combination with the first aspect, in certain implementations of the first aspect, the first supporting surface is connected to the first limiting surface; the electrical connector further includes: a fifth supporting surface, fixed on the first supporting surface and connected to the second limiting surface.

[0048] In the embodiment of the present application, since the first limiting surface is fixed to the circuit board through the first supporting surface, and the second limiting surface is fixed to the circuit board through the fifth supporting surface and the first supporting surface, it is not necessary to additionally process the insertion hole for fixing the electrical connector on the circuit board, thereby saving the space occupied by the electrical connector on the circuit board.

[0049] Optionally, the first supporting surface is used to be electrically connected to the fifth supporting surface.

[0050] In combination with the first aspect, in certain implementations of the first aspect, the contact force of the frame acting on the abutting area is located on the plane where the first supporting surface is located.

[0051] In the embodiment of the present application, the center position of the abutment area is located on the plane where the first supporting surface is located, which is beneficial to reduce or even eliminate the torque generated by the contact force on the first supporting surface, thereby facilitating stable installation of the electrical connector on the circuit board.

The power supply 241 is electrically connected to the first circuit board 242, so that the power supply 241 can supply power to the first circuit board 242. The electronic components in the electronic device 200 can be disposed on the circuit board. For example, the electronic components ( Figure 2 The first circuit board 242 is fixed to the first circuit board 242 (not shown). The solder ball is electrically connected between the first circuit board 242 and the electronic component, so that the power supply 241 can supply power to the electronic component on the first circuit board 242 through the first circuit board 242. In addition, the side frame 221 of the housing 220 can serve as a part of the electronic component to realize some functions of the electronic component. For example, a part of the side frame 221 can serve as an antenna radiator of the antenna module to realize the function of transmitting or receiving signals. Figure 2As shown, the side frame 221 includes a first part 222, a second part 223, a third part 224, a fourth part 225, and a fifth part 226, wherein the materials of the first part 222, the third part 224, and the fifth part 226 are all conductive materials, and the materials of the second part 223 and the fourth part 225 are all insulating materials. The second part 223 is adjacent to the first part 222 and the third part 224 to block the electrical connection between the first part 222 and the third part 224; the fourth part 225 is adjacent to the third part 224 and the fifth part 226 to block the electrical connection between the third part 224 and the fifth part 226. The housing 220 includes a third groove 233 for accommodating the second circuit board 243. Electrical connectors can be respectively provided between the second circuit board 243 and the first part 222, between the second circuit board 243 and the third part 224, and between the second circuit board 243 and the fifth part 226, so that the second circuit board 243 can supply power to the first part 222, the third part 224, and the fifth part 226 respectively. Thus, the first portion 222 may function as a first antenna radiator, the third portion 224 may function as a second antenna radiator, and the third portion 224 may function as a third antenna radiator.

[0104] like Figure 3 As shown, the electronic device 300 includes a display screen 310, a back cover 360 and a middle frame 320. The material of the middle frame 320 may include a conductive material, such as a metal material. The periphery 321 of the middle frame 320 (hereinafter referred to as the middle frame periphery 321) can serve as a side frame of the electronic device, that is, the middle frame periphery 321 surrounds the periphery of the display screen 310 and surrounds the periphery of the back cover 360, and the back cover 360 and the display screen 310 are respectively located on both sides of the middle frame 320. It can be seen that the back cover 360 and the middle frame 320 can be two different components, and the housing 120 of the electronic device 200 can be formed by assembling the back cover and the middle frame 320 together. The middle frame 320 includes a plurality of grooves for accommodating a power supply and a circuit board. As shown Figure 3 As shown, a power supply 341 is disposed in the first groove 331, and a first circuit board 342 is disposed in the second groove 332. The power supply 341 is electrically connected to the first circuit board 342, so that the power supply 341 can supply power to the first circuit board 342. The electronic components in the electronic device 300 can be disposed on the circuit board. In addition, the periphery 321 of the middle frame can serve as a part of the electronic component to realize some functions of the electronic component. For example, a part of the periphery 321 of the middle frame can serve as an antenna radiator of the antenna module to realize the function of transmitting or receiving signals. Figure 3As shown, the periphery of the middle frame 321 includes a first part 322, a second part 323, a third part 324, a fourth part 325, and a fifth part 326, wherein the materials of the first part 322, the third part 324, and the fifth part 326 are all conductive materials, and the materials of the second part 323 and the fourth part 325 are all insulating materials. The second part 323 is adjacent to the first part 322 and the third part 324 to block the electrical connection between the first part 322 and the third part 324; the fourth part 325 is adjacent to the third part 324 and the fifth part 326 to block the electrical connection between the third part 324 and the fifth part 326. Electrical connectors can be respectively provided between the first circuit board 342 and the first part 322, between the first circuit board 342 and the third part 324, and between the first circuit board 342 and the fifth part 326, and the first circuit board 342 can supply power to the first part 322, the third part 324, and the fifth part 326 respectively. Thus, the first portion 322 may function as a first antenna radiator, the third portion 324 may function as a second antenna radiator, and the third portion 324 may function as a third antenna radiator.

[0105] like Figure 4 As shown, the electronic device includes a display screen 410, a shell 420 and a middle frame 430. The shell 420 includes a side frame 421 and a back cover. The side frame 421 and the back cover are two parts of the shell 420 respectively, and the side frame 421 is connected to the back cover, and the connection between the side frame 421 and the back cover is usually inseparable. The material of the middle frame 421 may include a conductive material, such as a metal material. The middle frame 430 is accommodated in a cavity between the display screen 410, the side frame 421 and the back cover. The middle frame 430 includes a plurality of grooves for accommodating a power supply and a circuit board. As shown Figure 4 As shown, a power supply 441 is disposed in the first groove 431, and a first circuit board 442 is disposed in the second groove 432. The power supply 441 is electrically connected to the first circuit board 442, so that the power supply 441 can supply power to the first circuit board 442. The electronic components in the electronic device 400 can be disposed on the circuit board. In addition, the side frame 421 of the housing 420 can serve as a part of the electronic components to realize some functions of the electronic components. For example, Figure 4As shown, the side frame 421 includes a first part 422, a second part 423, and a third part 424, wherein the material of the second part 423 is a conductor material, and the materials of the first part 422 and the third part 424 are both insulating materials. The first part 422 and the third part 424 are respectively adjacent to the two sides of the second part 423, so that the first part 422 and the third part 424 can block the electrical connection between the second part 423 and other parts of the side frame 421 except the first part 422, the second part 423, and the third part 424. In order to supply power to the second part 423 of the side frame 421, an electrical connector can be provided between the first circuit board and the periphery 433 of the middle frame 430 (hereinafter referred to as the middle frame periphery 433), and the middle frame periphery 433 is electrically connected to the housing 420. Thus, the second part 423 can act as an antenna radiator.

[0106] As described above, an electrical connector may be provided between the circuit board and the middle frame, or between the circuit board and the housing, so as to supply power to the housing of the electronic device. Figure 5 A schematic diagram of a structure in which an electrical connector 530 is provided between a circuit board 510 and a frame 520 is shown. The circuit board 510 may be Figure 2 The second circuit board 243 in the circuit board 510 can also be Figure 3 The first circuit board 342 in the circuit board 510 can also be Figure 4 The first circuit board 442 in the frame 520 can be Figure 2 The side frame 421 in the frame 520 can also be Figure 3 The middle frame periphery 321 in the middle frame; the frame 520 can also be Figure 4 The periphery of the middle frame is 433. Figure 5 As shown, the circuit board 510 is located on one side of the frame 520, and the electrical connector 530 is fixed on the circuit board 510 and electrically connected to the circuit board 510. The electrical connector 530 includes an abutment area 531, which abuts on the side of the frame 520 close to the circuit board 510, so that the electrical connector 530 can be electrically connected between the circuit board 510 and the frame 520. The circuit board 510, the frame 520, and the electrical connector 530 are assembled together, for example, an antenna module can be obtained. The circuit board 510 can feed the frame 520 through the electrical connector 530, or realize the grounding of the frame 520. The part of the frame 520 that contacts the abutment area 531 can be an antenna radiator in the antenna module. The radio frequency module of the antenna module can be set on the circuit board 510. The antenna module can realize functions such as 2G, 3G, 4G, NFC, Bluetooth, WLAN, etc.

[0107] Below through Figures 6 to 18 The specific structure of the electrical connector is described in detail. It can be understood that Figures 6 to 18The embodiments shown are only intended to help those skilled in the art to better understand the technical solutions of the present application, but are not intended to limit the technical solutions of the present application.

[0108] Figure 6 The figure shows an electrical connector provided by an embodiment of the present application. The electrical connector 600 may be Figure 5 The electrical connector 510 in the embodiment of the present invention. Figure 5 Observe the electrical connector 510 in the direction indicated by the dashed arrow, and you can see Figure 6 A schematic structural diagram of the electrical connector shown. Figure 7 (a) shows a front view of the electrical connector 600, Figure 7 (b) shows a bottom view of the electrical connector 600. Figure 6 , Figure 7 The specific structure of the electrical connector 600 is described.

[0109] The electrical connector 600 may include a first limiting surface 611 and a second limiting surface 612 arranged in parallel. It should be understood that the first limiting surface 611 may be a curved surface. For example, the first limiting surface 611 may be a curved surface or a corrugated surface. Similarly, the second limiting surface 612 may be a curved surface. For example, the second limiting surface 612 may be a curved surface or a corrugated surface. If there is any plane of the first limiting surface 611 perpendicular to the thickness direction and parallel to any plane of the second limiting surface 612 perpendicular to the thickness direction, it can be considered that the first limiting surface 611 and the second limiting surface 612 are arranged in parallel.

[0110] The electrical connector 600 may also include a bearing surface 617 connected between the first limiting surface 611 and the second limiting surface 612. Among them, the bearing surface 617 may be located on the same side of the first limiting surface 611 and the second limiting surface 612, and the bearing surface 617 may be vertically arranged relative to the first limiting surface 611 and the second limiting surface 612. It should be understood that the bearing surface 617 may be a curved surface. For example, the bearing surface 617 may be an arc surface or a corrugated surface. If there is any plane of the first limiting surface 611 perpendicular to the thickness direction and any plane of the bearing surface 617 perpendicular to the thickness direction, it can be considered that the first limiting surface 611 and the bearing surface 617 are vertically arranged. Similarly, if there is any plane of the second limiting surface 612 perpendicular to the thickness direction and any plane of the bearing surface 617 perpendicular to the thickness direction, it can be considered that the second limiting surface 612 and the bearing surface 617 are vertically arranged.

[0111] The electrical connector 600 may also include a first extension arm 621. The first extension arm 621 is connected to the bearing surface 617 and extends out of the cavity formed by the first limiting surface 611, the second limiting surface 612, and the bearing surface 617; the end of the first extension arm 621 away from the bearing surface 617 includes a contact area 623. The contact area 623 is located outside the cavity formed by the first limiting surface 611, the second limiting surface 612, and the bearing surface 617, and is used to contact the frame of the electronic device; the contact torque (the direction of the torque is as shown in FIG. 6 ) of the frame of the electronic device acting on the contact area 623 Figure 7 The moment M in FIG6 (shown as the moment M in FIG6 ) is perpendicular to the first supporting surface 613, that is, perpendicular to the circuit board. Among them, the contact force of the frame of the electronic device acting on the abutment area 623 is perpendicular to the bearing surface 617. The first extension arm 621 can be approximately regarded as a force arm arranged in parallel between the first limiting surface 611 and the second limiting surface 612. According to the direction of the force arm and the direction of the contact force, it can be concluded that the abutment torque of the frame of the electronic device acting on the abutment area 623 is perpendicular to the circuit board. In other words, the torque acting on the electrical connector is perpendicular to the plane where the force arm and the force are located, so the electrical connector has a tendency to rotate parallel to the circuit board, that is, the force arm should be located on a plane parallel to the circuit board.

[0112] It should be noted that “component A is connected to component B” includes that component A and component B are connected together without any other component between component A and component B, and may also mean that component A and component B are connected together through component C.

[0113] It should be noted that "component 1 abuts component 2" generally means that component 1 is in contact with component 2; and at least one of the following conditions is met: Condition 1: the area of ​​the contact surface is greater than the first preset threshold; Condition 2: within the maximum contour of the contact surface, the number of uncontacted points is less than the second preset threshold; Condition 3: within the maximum contour of the contact surface, the area of ​​the uncontacted surface is less than the third preset threshold. Current conduction can be achieved through the contact between component 1 and component 2. However, if the area of ​​the contact surface is too small, or the contact is not tight enough, there may be a large number of uncontacted points in the contact surface, then arcing is likely to occur, and the requirements for stable electrical connection cannot be met. In order to achieve abutment between component 1 and component 2, the contact force between the abutment area 623 and the frame of the electronic device should be greater than the fourth preset threshold.

[0114] It should be noted that the present application does not limit the specific shape of the abutting area. Figure 6 , Figure 7 The abutment region 623 shown is in the shape of a convex hull, such as a parabolic convex hull, an ellipsoidal convex hull, or a spherical convex hull. The abutment region 623 may also not include a convex hull.

[0115] The electrical connector 600 may also include a second extension arm 622. The second extension arm 622 is connected to the abutment area 623. One end of the second extension arm 622 away from the abutment area 623 is used to abut on the bearing surface 617. In other words, the bearing surface 617 can be electrically connected to the frame of the electronic device through the first extension arm 621 and the second extension arm 622. It should be understood that in the present application, in order to facilitate the division of the first extension arm 621 and the second extension arm 622, the second extension arm 622 can be regarded as being located in the cavity formed by the first limiting surface 611, the second limiting surface 612, and the bearing surface 617; the portion of the first extension arm 621 located outside the cavity formed by the first limiting surface 611, the second limiting surface 612, and the bearing surface 617 can be regarded as the abutment area 623.

[0116] It should be understood that the end of the second extension arm 622 away from the abutment area 623 is used to abut against the bearing surface 617, which may refer to the case where the electrical connector 600 is installed inside the electronic device (i.e., the electrical connector 600 is in a working state), the end of the second extension arm 622 away from the abutment area 623 abuts against the bearing surface 617. When the electrical connector 600 is not installed inside the electronic device (i.e., the electrical connector 600 is in a free state), the end of the second extension arm 622 away from the abutment area 623 may not contact the bearing surface 617, or may contact the bearing surface 617. It should be noted that one possible situation requires electroplating of the electrical connector 600. When the electrical connector 600 is in a free state, the end of the second extension arm 622 away from the abutment area 623 does not contact the bearing surface 617, which can ensure that the surface of the second extension arm 622 is completely electroplated with a thin film. When the electrical connector 600 is in a free state, the end of the second extension arm 622 away from the abutment area 623 is in contact with the bearing surface 617. Then, the part where the second extension arm 622 contacts the bearing surface 617 cannot be electroplated, which may affect the electrical connection performance of the electrical connector. Figure 7 The partial enlarged view in FIG. 6 shows a possible situation that the electrical connector 600 has not been installed in the electronic device. In this situation, there may be a gap A between the second extension arm 622 and the bearing surface 617 .

[0117] The electrical connector 600 may include a first hanging ear 625 and a second hanging ear 626. The first hanging ear 625 extends into the first hole 631 on the first limiting surface 611. Therefore, the movable space of the first hanging ear 625 may be limited by the outline of the first hole 631. The second hanging ear 626 extends into the second hole 632 on the second limiting surface 612. Therefore, the movable space of the second hanging ear 626 may be limited by the outline of the second hole 632. By reasonably setting the sizes of the first hanging ear 625 and the second hanging ear 626, the first hanging ear 625 can be prevented from detaching from the first hole 631 and the second hanging ear 626 from the second hole 632. The first hanging ear 625 can be arranged on the first extension arm 621, the abutment area 623 or the second extension arm 622. Similarly, the second hanging ear 626 can be arranged on the first extension arm 621, the abutment area 623 or the second extension arm 622. Figure 6 The illustrated example shows that both the first hanging ear 625 and the second hanging ear 626 are disposed on the second extension arm 622 .

[0118] The electrical connector 600 may also include a first support surface 613 and a second support surface 614 for contacting the circuit board and arranged on one side of the circuit board. The first support surface 613 and the second support surface 614 are located between the abutment area 623 and the bearing surface 617. The first support surface 613 may be connected to an end of the first limit surface 611 away from the first extension arm 621 (i.e., close to the second extension arm 622), and the second support surface 614 may be connected to an end of the first limit surface 611 close to the first extension arm 621. The plane where the first support surface 613 is located may be located between the first limit surface 611 and the second limit surface 612, and the plane where the second support surface 614 is located may be located between the first limit surface 611 and the second limit surface 612. Therefore, a part of the electrical connector 600 may be buried in the circuit board, which is conducive to reducing the space occupied by the electrical connector 600 (for example, reducing the space occupied by the electrical connector 600 in the thickness direction of the electronic device) to reduce the thickness of the electronic device, thereby meeting the requirements of the electronic device for thinness. Optionally, the first limiting surface 611 can be arranged parallel to the first supporting surface 613 or the second supporting surface 614, so that the first limiting surface 611 can be arranged parallel to the circuit board. Optionally, the second limiting surface 612 can be arranged parallel to the first supporting surface 613 or the second supporting surface 614, so that the second limiting surface 612 can be arranged parallel to the circuit board.

[0119] It should be noted that the contact relationship between the first support surface 613 (or the second support surface 614) and the circuit board includes movable contact and immovable contact (i.e. fixed). In the case where there is a movable contact relationship between the first support surface 613 (or the second support surface 614) and the circuit board, the electrical connector 600 is not fixed to the circuit board through the first support surface 613 (or the second support surface 614); in the case where there is an immovable contact relationship between the first support surface 613 (or the second support surface 614) and the circuit board, the electrical connector 600 can be fixed to the circuit board through the first support surface 613 (or the second support surface 614). It should be noted that in the case where there is an immovable contact relationship between the first support surface 613 (or the second support surface 614) and the circuit board, it is easier to ensure that the electrical connector 600 can be firmly fixed to the circuit board.

[0120] It should be noted that, given the contact force between the abutment area 623 and the frame of the electronic device, the contact force will generate a torque on the portion of the electrical connector 600 that contacts the circuit board. That is, the contact force of the frame of the electronic device acting on the abutment area 623 is located on the plane where the first support surface 613 (or the second support surface 614) is located. In the case where the center position of the abutment area 623 is located on the plane of the first support surface 613 (or the second support surface 614) for contacting the circuit board, it is helpful to reduce or even eliminate the torque generated by the contact force on the first support surface 613 and the second support surface 614.

[0121] The electrical connector 600 may further include a first connection surface 615 and a second connection surface 616. The first connection surface 615 may be connected to an end of the second limiting surface 612 close to the first supporting surface 613, and the second connection surface 616 may be connected to an end of the second limiting surface 612 close to the second supporting surface 614. In addition, the first connection surface 615 may be located between the first supporting surface 613 and the second limiting surface 612, and the second connection surface 616 may be located between the second supporting surface 614 and the second limiting surface 612. Optionally, both the first connection surface 615 and the second connection surface 616 may be arranged parallel to the second limiting surface 612.

[0122] It should be noted that, in the present application, the limiting surface, the supporting surface, and the connecting surface are all surface bodies. The plane where the surface body is located can be any plane within the thickness range of the surface body and perpendicular to the thickness direction.

[0123] The electrical connector 600 may also include a first fixed end 641, a second fixed end 642, a third fixed end 643 and a fourth fixed end 644. The first fixed end 641, the second fixed end 642, the third fixed end 643 and the fourth fixed end 644 may be used to be inserted and fixed in the insertion hole of the circuit board. Among them, the first fixed end 641 may be connected to the side of the first support surface 613 away from the first limiting surface 611; the second fixed end 642 may be connected to the side of the second support surface 614 away from the first limiting surface 611. The third fixed end 643 may be connected to an end of the second limiting surface 612 close to the first supporting surface 613; the fourth fixed end 644 may be connected to an end of the second limiting surface 612 close to the second supporting surface 613. For example, the third fixed end 643 may be connected to the side of the first connection surface 615 away from the second limiting surface 612; the fourth fixed end 644 may be connected to the side of the second connection surface 616 away from the second limiting surface 612. Since there is a contact force between the abutting area 623 and the frame of the electronic device, the bearing surface 617 tends to tilt and deform due to the contact force. By fixing the first fixed end 641, the second fixed end 642, the third fixed end 643 and the fourth fixed end 644 on the circuit board, the first limiting surface 611 and the second limiting surface 612 can be constrained from moving, thereby preventing the bearing surface 617 from tilting.

[0124] The one or more components for contacting the circuit board include at least one component for electrically connecting to the circuit board.

[0125] In an example, the first fixed end 641 , the second fixed end 642 , the third fixed end 643 , and the fourth fixed end 644 are all used to be electrically connected to a circuit board. Then, the circuit board can be electrically connected to the frame of the electronic device through the first fixed end 641, the first limiting surface 611, the supporting surface 617, the first extension arm 621 (or the second extension arm 622), and the abutment area 623; the circuit board can be electrically connected to the frame of the electronic device through the second fixed end 642, the first limiting surface 611, the supporting surface 617, the first extension arm 621 (or the second extension arm 622), and the abutment area 623; the circuit board can also be electrically connected to the frame of the electronic device through the third fixed end 643, the second limiting surface 612, the supporting surface 617, the first extension arm 621 (or the second extension arm 622), and the abutment area 623; the circuit board can be electrically connected to the frame of the electronic device through the fourth fixed end 644, the second limiting surface 612, the supporting surface 617, the first extension arm 621 (or the second extension arm 622), and the abutment area 623.

[0126] In one example, the first support surface 613 and the second support surface 614 are both used to electrically connect to the circuit board. Then, the circuit board can be electrically connected to the frame of the electronic device through the first support surface 613, the first limiting surface 611, the bearing surface 617, the first extension arm 621 (or the second extension arm 622), and the abutment area 623; the circuit board can also be electrically connected to the frame of the electronic device through the first support surface, the second limiting surface 612, the bearing surface 617, the first extension arm 621 (or the second extension arm 622), and the abutment area 623.

[0127] Figure 8 The four states of the electrical connector 600 are shown. The four states may include state 1, state 2, state 3 and state 4. Among them, state 1 may be the free state of the electrical connector 600. State 2, state 3 and state 4 may all be the working states of the electrical connector 600. The spacing may be used to indicate the spacing between the farthest end of the abutment area 623 away from the bearing surface 617 and the bearing surface 617. Spacing 1, spacing 2, spacing 3 and spacing 4 correspond to state 1, state 2, state 3 and state 4, respectively. It can be seen that spacing 1> spacing 2> spacing 3> spacing 4.

[0128] When the electrical connector 600 is in state 1, the electrical connector 600 has not been installed inside the electronic device, and the contact area 623 of the electrical connector 600 may not contact the frame of the electronic device. Therefore, when the electrical connector 600 is in state 1, the distance between the farthest end of the contact area 623 away from the bearing surface 617 and the bearing surface 617 is the largest. When the electrical connector 600 is in state 2, state 3, or state 4, the electrical connector 600 is installed inside the electronic device, and the contact area 623 of the electrical connector 600 may contact the frame of the electronic device.

[0129] When the electrical connector 600 is in state 2, the contact area 623 of the electrical connector 600 just contacts the frame of the electronic device, or the contact stress between the contact area 623 of the electrical connector 600 and the frame of the electronic device is greater than the fifth preset threshold. In other words, state 2 can represent the first critical working state of the electrical connector 600. In this first critical working state, the electrical connector 600 can be stably electrically connected between the circuit board and the frame of the electronic device, and the spacing between the electrical connector 600 and the frame of the electronic device is the maximum permissible spacing, that is, the spacing between the electrical connector 600 and the frame of the electronic device cannot be greater than the maximum permissible spacing, because if the spacing between the electrical connector 600 and the frame of the electronic device is greater than the maximum permissible spacing, the electrical connector 600 and the frame of the electronic device cannot be stably contacted.

[0130] When the electrical connector 600 is in state 4, the first limiting surface 611 and / or the second limiting surface 612 of the electrical connector 600 are about to contact the frame of the electronic device, or the contact stress between the abutment area 623 of the electrical connector 600 and the frame of the electronic device is less than the sixth preset threshold, and the sixth preset threshold is greater than the fifth preset threshold. In other words, state 4 can represent the second critical working state of the electrical connector 600. In this second critical working state, the electrical connector 600 can be stably electrically connected between the circuit board and the frame of the electronic device, and the spacing between the electrical connector 600 and the frame of the electronic device is the minimum permissible spacing, that is, the spacing between the electrical connector 600 and the frame of the electronic device cannot be less than the minimum permissible spacing, because if the spacing between the electrical connector 600 and the frame of the electronic device is less than the minimum permissible spacing, the electrical connector 600 and the frame of the electronic device cannot be stably in contact.

[0131] State 3 can be any state between state 2 and state 4, that is, the abutment area 623 of the electrical connector 600 stably and firmly presses the frame of the electronic device, and the distance between the electrical connector 600 and the frame of the electronic device is greater than the minimum allowable distance and less than the maximum allowable distance.

[0132] It should be noted that the second extension arm 622 always contacts the bearing surface 617 when the electrical connector 600 changes between states 2, 3 and 4. That is, when the electrical connector 600 is in any state among states 2, 3 and 4, only the second extension arm 622 contacts the bearing surface 617 stably.

[0133] The movable space of the first hanging ear 625 may be limited by the contour of the first hole 631. When the electrical connector 600 is in any of the states 2, 3 and 4, there may be two possible situations: in one situation, the first hanging ear 625 always stably abuts against the contour of the first hole 631; in another situation, the first hanging ear 625 never contacts the contour of the first hole 631. If the first hanging ear 625 always stably abuts against the contour of the first hole 631, it can bear the contact force generated by a part of the abutting area 623 abutting against the frame of the electronic device. Similarly, the movable space of the second hanging ear 626 may be limited by the contour of the second hole 632. When the electrical connector 600 is in any of the states 2, 3 and 4, the second hanging ear 626 may always stably abut against the contour of the second hole 632; or, the second hanging ear 626 may never contact the contour of the second hole 632. If the second hanging ear 626 always stably abuts against the contour of the second hole 632, it can bear the contact force generated by a portion of the abutting area 623 abutting against the frame of the electronic device.

[0134] It should be noted that, in view of the contact force between the abutment area 623 and the frame of the electronic device, the contact force will generate a first torque on the first fixed end 641, and the contact force will generate a second torque on the second fixed end 642 in the opposite direction of the first torque. In order to reduce the torque generated by the contact force on the part where the electrical connector 600 contacts the circuit board, the real working state of the electrical connector 600 can be set to be the same or approximately the same as the first distance and the second distance, wherein the first distance is the distance between the abutment area 623 and the first fixed end 641, and the second distance is the distance between the abutment area 623 and the second fixed end 642. Similarly, in order to reduce the torque generated by the contact force on the part where the electrical connector 600 contacts the circuit board, the real working state of the electrical connector 600 can be set to be the third distance and the fourth distance, wherein the third distance is the distance between the abutment area 623 and the third fixed end 643, and the fourth distance is the distance between the abutment area 623 and the fourth fixed end 644. Then, when the electrical connector 600 is in state 1, the abutment area 623 can be relatively closer to the second fixed end 642 (or the fourth fixed end 644); when the electrical connector 600 is in state 4, the abutment area 623 can be relatively closer to the first fixed end 641 (or the third fixed end 643). That is to say, in the free state, the abutment area 623 is relatively closer to the second fixed end 642 (or the fourth fixed end 644), and as the distance between the abutment area 623 and the bearing surface 617 becomes smaller (for example, the abutment area is moved from the outside of the cavity formed by the first limiting surface, the second limiting surface and the bearing surface to the inside of the cavity), the abutment area 623 can be moved from a position closer to the second fixed end 642 (or the fourth fixed end 644) to a position closer to the first fixed end 641 (or the third fixed end 643).

[0135] like Fig. 9 As shown, the embodiment of the present application further provides an electrical connector 700. The electrical connector 700 and Figure 6 (or Figure 7) includes that the electrical connector 700 does not include the first hanging ear 625, the second hanging ear 626, the first hole 631, and the second hole 632 of the electrical connector 600. That is, in the electrical connector 700, no hanging ear is provided on the second extension arm 722, and no hole for restricting the movement of the hanging ear is provided on the first limiting surface 711 and the second limiting surface 712. For the electrical connector 600, since the movable space of the first hanging ear 625 is restricted by the first hole 631, and the movable space of the second hanging ear 626 is restricted by the second hole 632, the abutment area 623 will not excessively extend out of the cavity formed by the first limiting surface 611, the second limiting surface 612 and the bearing surface 617. In the process of transporting and installing the electrical connector 600, it is helpful to avoid excessive bending of the first extension arm 621 in the direction away from the bearing surface 617, thereby reducing the possibility of damage to the electrical connector 600. However, since the electrical connector 700 does not have a lug and a hole for constraining the movement of the lug, the processing technology of the electrical connector 700 can be reduced or simplified. For example, for the electrical connector 600, it is necessary to control the position tolerance between the first lug 625 and the first hole 631, and the position tolerance between the second lug 626 and the second hole 632, so the processing difficulty of the electrical connector 700 is lower than that of the electrical connector 600. In appropriate cases (for example, the material strength of the electrical connector is high and it is not easy to change the angle of the first extension arm relative to the bearing surface), the lug for constraining the movement of the abutment area and the hole for constraining the movement of the lug may not be provided on the electrical connector.

[0136] It should be noted that Figure 6 (or Figure 7 ) The electrical connector 600 shown in FIG. 1 includes two hanging ears. Fig. 9 The electrical connector 700 shown does not include a lug. In addition, the electrical connector may include only one lug and a hole for constraining the lug. For example, it includes a first lug 625 as in the electrical connector 600 and a first hole 631 constraining the first lug 625, or includes a second lug 626 as in the electrical connector 600 and a first hole 632 constraining the second lug 626. In the case where the electrical connector includes only one lug, the difficulty of processing the electrical connector is between the electrical connector 600 and the electrical connector 700; and the difficulty of destroying the electrical connector is between the electrical connector 600 and the electrical connector 700.

[0137] like Fig.10 As shown, the present embodiment also provides an electrical connector 800. The electrical connector 800 and Fig. 9The difference between the electrical connector 700 shown includes that the electrical connector 800 does not include an extension arm abutting against the bearing surface 817 (i.e., does not include the second extension arm 722 of the electrical connector 700). In the electrical connector 700, the electrical connection between the bearing surface 717 of the electrical connector 700 and the frame of the electronic device can be achieved through the first extension arm 721 and the second extension arm 722; while in the electrical connector 800, the electrical connection between the bearing surface 817 of the electrical connector 800 and the frame of the electronic device can only be achieved through the first extension arm 821. For the electrical connector 700, since the current can pass through the first extension arm 721 and the second extension arm 722, the current that can be transmitted by the electrical connector 700 is higher than the current that can be transmitted by the electrical connector 800 under the same voltage. In addition, since the second extension arm 722 can abut against the bearing surface 717, the contact force that the abutment area 723 of the electrical connector 700 can withstand is higher than the contact force that the abutment area 823 of the electrical connector 800 can withstand. As described above, the greater the contact force, the more conducive it is to avoiding arcing. Therefore, compared with the electrical connector 800, the electrical connector 700 is less likely to produce arcing and is more likely to be in a stable working state. However, in order to ensure that the second extension arm 722 can stably abut against the bearing surface 717, the difficulty of processing the electrical connector 700 is higher than the difficulty of processing the electrical connector 800. Therefore, under appropriate conditions (for example, the current that the electrical connector needs to transmit is small, or the contact force that the electrical connector withstands is large enough), the electrical connector may not include an extension arm abutting against the bearing surface.

[0138] like Fig.11 As shown, the embodiment of the present application further provides an electrical connector 900 . Fig.11 The electrical connector 900 is shown with Figure 6 (or Figure 7) includes that the electrical connector 900 does not include the first connection surface 615 and the second connection surface 616 of the electrical connector 600. With respect to the electrical connector 600, since the first connection surface 615 and the second connection surface 616 are located between the first support surface 613 or the second support surface 614 and the second limiting surface 612, the space occupied by the electrical connector 600 is smaller than the space occupied by the electrical connector 900. Therefore, the electrical connector 600 can improve the flatness of the electronic device and improve the compactness of the assembly of the components inside the electronic device. In addition, the symmetry of the electrical connector 600 is higher than that of the electrical connector 900, wherein when the first limiting surface 611 of the electrical connector 600 is (approximately) symmetrical with the second limiting surface 612, the first supporting surface 613 is (approximately) symmetrical with the first connecting surface 615, and the second supporting surface 614 is (approximately) symmetrical with the second connecting surface 616; when the first limiting surface 911 of the electrical connector 900 is (approximately) symmetrical with the second limiting surface 912, the first supporting surface 913 is asymmetrical with the second limiting surface 912, and the second supporting surface 914 is asymmetrical with the second limiting surface 912. Therefore, the mechanical stability of the electrical connector 600 is higher than that of the electrical connector 900. However, in order to form the connecting surface, it is necessary to process the connecting ribs between the connecting surface and the limiting surface and the connecting ribs between the connecting surface and the fixed end, so the processing difficulty of the electrical connector 900 is lower than that of the electrical connector 600. In appropriate circumstances (for example, the electrical connector does not substantially affect the assembly of components within the electronic device, or the electrical connector has high mechanical stability), the first connection surface 615 and the second connection surface 616 such as in the electrical connector 600 may not be provided on the electrical connector.

[0139] like Fig.12 As shown, the embodiment of the present application also provides an electrical connector 1500 . Fig.12 The electrical connector 1500 shown is Figure 6 or Figure 7 Compared with the electrical connector 600 shown, the electrical connector 1500 may include a first limiting ear 1533 and a second limiting ear 1534 .

[0140] The electrical connector 1500 may include a first limiting surface 1511 and a second limiting surface 1512 arranged in parallel, and a bearing surface 1517 connected between the first limiting surface 1511 and the second limiting surface 1512. The bearing surface 1517 may be located on the same side of the first limiting surface 1511 and the second limiting surface 1512, and the bearing surface 1517 may be arranged perpendicularly relative to the first limiting surface 1511 and the second limiting surface 1512.

[0141] The electrical connector 1500 may further include a first extension arm 1521. The first extension arm 1521 is connected to the bearing surface 1517 and extends out of the cavity formed by the first limiting surface 1511, the second limiting surface 1512 and the bearing surface 1517; one end of the first extension arm 1521 away from the bearing surface 1517 includes a contact area 1523. The contact area 1523 is located outside the cavity formed by the first limiting surface 1511, the second limiting surface 1512 and the bearing surface 1517, and is used to contact the frame of the electronic device; the contact torque of the frame of the electronic device acting on the contact area 1523 is perpendicular to the circuit board.

[0142] The electrical connector 1500 may further include a first limiting ear 1533 and a second limiting ear 1534. The first limiting ear 1533 is connected to a side of the first limiting surface 1511 away from the bearing surface 1517; an end of the first limiting ear 1533 away from the first limiting surface 1511 extends toward the second limiting surface 1512. The second limiting ear 1534 is connected to a side of the second limiting surface 1512 away from the bearing surface 1517; an end of the second limiting ear 1534 away from the second limiting surface 1512 extends toward the first limiting surface 1511.

[0143] The electrical connector 1500 may further include a third extension arm 1524. The third extension arm 1524 is connected to the abutment area 1523. One end of the third extension arm 1524 away from the abutment area 1523 is located between the bearing surface 1517 and the first limiting ear 1533, and is located between the bearing surface 1517 and the second limiting ear 1534. The projection area of ​​the third extension arm 1524 on the bearing surface 1517 partially overlaps with the projection area of ​​the first limiting ear 1533 on the bearing surface 1517, and the projection area of ​​the third extension arm 1524 on the bearing surface 1517 partially overlaps with the projection area of ​​the second limiting ear 1534 on the bearing surface 1517. Therefore, when the extension angle of the third extension arm 1524 relative to the bearing surface 1517 is changed, due to the presence of the first limiting ear 1533 and the second limiting ear 1534, the end of the third extension arm 1524 close to the bearing surface 1517 will not move out of the cavity formed by the first limiting surface 1511, the second limiting surface 1512, and the bearing surface 1517. Therefore, the movable space of the third extension arm 1524 away from the bearing surface 1517 is limited by the first limiting ear 1533 and the second limiting ear 1534. The end of the third extension arm 1524 away from the abutting area 1523 may not contact the bearing surface 1517, and may also be used to abut on the bearing surface 1517.

[0144] The electrical connector 1500 constrains the third extension arm 1524 through the first limiting ear 1533 and the second limiting ear 1534; while the electrical connector 600 constrains the second extension arm 622 through the first limiting surface 611, the second limiting surface 612, the first hole 631, the second hole 632, the first hanging ear 625, and the second hanging ear 626. In the case where the third extension arm 1524 of the electrical connector 1500 may not contact the bearing surface 1517, the electrical connector 1500 can only realize the electrical connection between the bearing surface 1516 of the electrical connector 1500 and the frame of the electronic device through the first extending arm 1521. In the electrical connector 600, the bearing surface 616 of the electrical connector 600 and the frame of the electronic device can be realized through the first extending arm 621 and the second extending arm 622. Therefore, under the same voltage, the current that the electrical connector 600 can transmit is higher than the current that the electrical connector 1500 can transmit. In addition, since the second extension arm 622 can abut against the bearing surface 616, the contact force that the abutting area 623 of the electrical connector 600 can withstand is higher than the contact force that the abutting area 1523 of the electrical connector 1500 can withstand. As described above, the greater the contact force, the more conducive it is to avoiding arcing. Therefore, compared with the electrical connector 1500, the electrical connector 600 is less likely to produce arcing and is more likely to be in a stable working state.

[0145] Since the structures of the first limiting ear 1533 and the second limiting ear 1524 of the electrical connector 1500 are complex, the difficulty of processing the electrical connector 1500 is higher than that of processing the electrical connector 600 .

[0146] Assume that the distance between the side of the third extension arm 1524 close to the second limiting surface 1512 and the side of the third extension arm 1524 close to the first limiting surface 1511 is a distance 5, and the distance between the side of the second extension arm 622 close to the second limiting surface 612 and the side of the second extension arm 622 close to the first limiting surface 611 is a distance 6. When the distance 5 is the same as the distance 6, the first limiting ear 1533 and the second limiting ear 1534 of the electrical connector 1500 can strengthen the movable space of the third extension arm 1524 in the cavity formed by the first limiting surface 611, the second limiting surface 612 and the bearing surface 617. Therefore, the electrical connector 1500 is less likely to be damaged during transportation and installation.

[0147] like Fig.13 As shown, the embodiment of the present application further provides an electrical connector 1600 . Fig.13 The electrical connector 1600 is shown with Figure 6 or Figure 7 Compared with the electrical connector 600 shown in FIG. 1 , the electrical connector 1600 may include a first hole ( Fig.13The electrical connector 1600 may include a first limiting surface 1611, a second limiting surface 1612, and a bearing surface 1617 connected between the first limiting surface 1611 and the second limiting surface 1612. The bearing surface 1617 may be located on the same side of the first limiting surface 1611 and the second limiting surface 1612, and the bearing surface 1617 may be vertically arranged relative to the first limiting surface 1611 and the second limiting surface 1612.

[0148] The electrical connector 1600 may further include a first extension arm 1621. The first extension arm 1621 is connected to the bearing surface 1617 and extends out of the cavity formed by the first limiting surface 1611, the second limiting surface 1612 and the bearing surface 1617; one end of the first extension arm 1621 away from the bearing surface 1617 includes a contact area 1623. The contact area 1623 is located outside the cavity formed by the first limiting surface 1611, the second limiting surface 1612 and the bearing surface 1617, and is used to contact the frame of the electronic device; the contact torque of the frame of the electronic device acting on the contact area 1623 is perpendicular to the circuit board.

[0149] The electrical connector 1600 may further include a first hanging ear ( Fig.13 The first hanging ear extends into the first hole (not shown) on the first limiting surface 1611. Fig.13 (not shown), the first hanging ear is used to abut against the contour of the first hole; the second hanging ear 1626 extends into the second hole 1632 on the second limiting surface 1612, and the second hanging ear 1626 is used to abut against the contour of the second hole 1632. That is, when the electrical connection 1600 is in a working state, the first hanging ear abuts against the contour of the first hole, and the second hanging ear 1626 abuts against the contour of the second hole 1632; while when the electrical connection 1600 is in a free state, the first hanging ear may or may not contact the contour of the first hole, and the second hanging ear 1626 may or may not contact the contour of the second hole 1632. The first hanging ear and the second hanging ear 1626 may be arranged on the first extension arm 1621, the abutment area 1623 or the fourth extension arm 1627. Fig.13 The example shown is that both the first hanging ear and the second hanging ear 1626 are arranged on the fourth extension arm 1627 .

[0150] Fig.13 The electrical connector 1600 is shown with Figure 6 (or Figure 7) include that the fourth extension arm 1627 of the electrical connector 1600 can not only bear the reaction force exerted by the abutment area 1623; moreover, the force exerted by the first hanging ear on the first hole can generate a moment 1 on the part of the first support surface 1613 that contacts the circuit board, and the force exerted by the second hanging ear 1632 on the second hole 1626 can generate a moment 2 on the part of the second support surface 1614 that contacts the circuit board, and the moment 1 and the moment 2 can approximately offset each other, thereby reducing the possibility of the bearing surface 1617 tilting. Therefore, compared with the electrical connector 600, the electrical connector 1600 has stronger mechanical stability. However, in actual operation, the first extension arm 1621 may be deflected, and the force exerted by the first hanging ear on the first hole is different from the force exerted by the second hanging ear 1632 on the second hole 1626. Therefore, the contact impedance between the first hanging ear and the first hole is different from the contact impedance between the second hanging ear 1632 and the second hole 1632, which may affect the electrical connection performance of the electrical connector 1600. Even more, if the first extension arm 1621 is severely deflected, resulting in only the first hanging ear contacting the first hole (i.e., the second hanging ear 1632 and the second hole 1626 are not in contact), or only the second hanging ear 1632 and the second hole 1626 are in contact (i.e., the first hanging ear and the first hole are not in contact), then the electrical connection performance of the electrical connector 1600 is more likely to be affected.

[0151] The above Figures 6 to 13 Various structures of electrical connectors are described. Since the manner of mounting electrical connectors 600, 700, 800, 900, 1500, and 1600 on a circuit board is very similar, for the sake of simplicity, only the electrical connector 600 is used as an example to describe in detail an embodiment of mounting the electrical connector on a circuit board. With the benefit of the guidance and enlightenment presented in the foregoing description and the related drawings, those skilled in the art will think of many improvements and other embodiments of the present application. Therefore, it should be understood that the present application is not limited to the specific embodiments disclosed.

[0152] Fig.14 1 is a schematic diagram of a circuit assembly with an electrical connector provided in an embodiment of the present application. The circuit assembly 1000 includes a circuit board 1010 and an electrical connector 600. The circuit board 1010 includes a groove 1011 for accommodating a first limiting surface 613 of the electrical connector 600. The first supporting surface 613 and the second supporting surface 614 of the electrical connector 600 are both in contact with one side of the circuit board 1010. Optionally, the first supporting surface 613 and the second supporting surface 614 are both fixed on one side of the circuit board 1010. The circuit board 1010 also includes a first insertion hole 1012 and a second insertion hole 1013. Among them, the first fixed end 641 ( Fig.14The second fixed end 642 (not shown) of the electrical connector is inserted into and fixed to the first insertion hole 1012. Fig.14 The fourth fixing end portion 644 extends into and is fixed in the second insertion hole 1013 .

[0153] Fig.15 1 is a schematic diagram of an electrical connector and a circuit assembly equipped with the electrical connector provided in an embodiment of the present application. The circuit assembly 1100 includes a circuit board 1101 and an electrical connector 1102. The specific structure of the electrical connector 1102 is first described below.

[0154] The electrical connector 1102 may include a first limiting surface 1111 and a second limiting surface 1112 arranged in parallel, and a bearing surface 1117 connected between the first limiting surface 1111 and the second limiting surface 1112. The bearing surface 1117 may be located on the same side of the first limiting surface 1111 and the second limiting surface 1112, and the bearing surface 1117 may be arranged perpendicularly relative to the first limiting surface 1111 and the second limiting surface 1112.

[0155] The electrical connector 1102 may further include a first extension arm 1121. The first extension arm 1121 is connected to the bearing surface 1117 and extends out of the cavity formed by the first limiting surface 1111, the second limiting surface 1112, and the bearing surface 1117. One end of the first extension arm 1121 away from the bearing surface 1117 includes an abutment area 1123. The abutment area 1123 is located outside the cavity formed by the first limiting surface 1111, the second limiting surface 1112, and the bearing surface 1117, and is used to abut against the frame of the electronic device, and the abutment torque of the frame acting on the abutment area 1123 is perpendicular to the circuit board.

[0156] The electrical connector 1102 also includes a first support surface 1113 and a second support surface 1114 for fixing to one side of the circuit board 1101. The first limiting surface 1111 is connected between the first supporting surface 1113 and the second supporting surface 1114. The plane where the first supporting surface 1113 is located can be located between the first limiting surface 1111 and the second limiting surface 1112, and the plane where the second supporting surface 1114 is located can be located between the first limiting surface 1111 and the second limiting surface 1112.

[0157] The electrical connector 1102 may further include a third fixed end 1143 and a fourth fixed end 1144 for fixing on the circuit board 1101. The third fixed end 1143 may be connected to an end of the second limiting surface 1112 close to the first supporting surface 1113; the fourth fixed end 1144 may be connected to an end of the second limiting surface 1112 close to the second supporting surface 1113.

[0158] Fig.14 The circuit assembly 1000 shown is Fig.15 The difference between the circuit assemblies 1100 includes that the electrical connector 1102 does not include the first fixed end 641 and the second fixed end 642 of the electrical connector 600. In addition, the electrical connector 1102 includes a first supporting surface 1113 and a second supporting surface 1114 for fixing on the circuit board 1101 and arranged on one side of the circuit board 1101. In addition, one or more components for contacting the circuit board 1101 include at least one component for electrically connecting to the circuit board 1101. The at least one component may include, for example, any one of the first supporting surface 1113, the second supporting surface 1114, the third fixed end 1143, and the fourth fixed end 1144.

[0159] The assembly relationship between the electrical connector 1102 and the circuit board 1101 is described below. The circuit board 1101 of the circuit assembly 1100 includes a groove 1103 for accommodating a first limiting surface 1111 of the electrical connector 1102. The first supporting surface 1113 and the second supporting surface 1114 of the electrical connector 1102 are fixed on one side of the circuit board 1101. The circuit board 1101 also includes a first insertion hole 1104 and a second insertion hole 1105, wherein the third fixed end 1143 of the electrical connector 1102 extends into and is fixed in the first insertion hole 1104, and the fourth fixed end 1144 of the electrical connector 1102 extends into and is fixed in the second insertion hole 1105.

[0160] For the electrical connector 1102, the first limiting surface 1111 of the electrical connector 1102 can only be fixed on the circuit board 1101 through the first supporting surface 1113 and the second supporting surface 1114. Therefore, there are fewer ways to fix the electrical connector 1102, the flexibility is relatively low, and it is not easy to ensure the stability of the installed circuit components. However, since the electrical connector 1102 omits the first fixed end 641 and the second fixed end 642 in the electrical connector 600, the difficulty of processing the electrical connector 1102 is lower than that of processing the electrical connector 600.

[0161] Fig.16 1 is a schematic diagram of an electrical connector and a circuit assembly equipped with the electrical connector provided in an embodiment of the present application. The circuit assembly 1200 includes a circuit board 1201 and an electrical connector 1202. The specific structure of the electrical connector 1202 is first described below.

[0162] The electrical connector 1202 may include a first limiting surface 1211 and a second limiting surface 1212 arranged in parallel, and a bearing surface 1217 connected between the first limiting surface 1211 and the second limiting surface 1212. The bearing surface 1217 may be located on the same side of the first limiting surface 1211 and the second limiting surface 1212, and the bearing surface 1217 may be arranged perpendicularly relative to the first limiting surface 1211 and the second limiting surface 1212.

[0163] The electrical connector 1202 may further include a first extension arm 1221. The first extension arm 1221 is connected to the bearing surface 1217 and extends out of the cavity formed by the first limiting surface 1211, the second limiting surface 1212, and the bearing surface 1217. One end of the first extension arm 1221 away from the bearing surface 1217 includes an abutment area 1223. The abutment area 1223 is located outside the cavity formed by the first limiting surface 1211, the second limiting surface 1212, and the bearing surface 1217, and is used to abut against the frame of the electronic device, and the abutment torque of the frame acting on the abutment area 1223 is perpendicular to the circuit board.

[0164] The electrical connector 1202 may also include a first support surface 1213 and a second support surface 1214 for fixing on the circuit board 1201 and arranged on one side of the circuit board 1201. The second limiting surface 1212 is connected between the first support surface 1213 and the second support surface 1214. The plane where the first support surface 1213 is located may be located between the first limiting surface 1211 and the second limiting surface 1212, and the plane where the second support surface 1214 is located may be located between the first limiting surface 1211 and the second limiting surface 1212. The electrical connector 1202 also includes a third support surface 1215 and a fourth support surface 1216. Among them, the first limiting surface 1211 is connected between the third support surface 1215 and the fourth support surface 1216. The third support surface 1215 is fixed on the side of the first support surface 1213 close to the second limiting surface 1212, and the fourth support surface 1216 is fixed on the side of the second support surface 1214 close to the second limiting surface 1212. Optionally, the first supporting surface 1213 is electrically connected to the third supporting surface 1215 .

[0165] Optionally, the electrical connector 1202 may further include a third connection surface 1218 connected between the first support surface 1213 and the second limit surface 1212, and a fourth connection surface 1219 connected between the second support surface 1214 and the second limit surface 1212. That is, the first support surface 1213 is connected to the second limit surface 1212 through the third connection surface 1218, and the second support surface 1214 is connected to the second limit surface 1212 through the fourth connection surface 1219. The third connection surface 1218 may be located between the third support surface 1215 and the second limit surface 1212, and the fourth connection surface 1219 may be located between the fourth support surface 1216 and the second limit surface 1212. Optionally, the third connection surface 1218 and the fourth connection surface 1219 may be arranged parallel to the second limit surface 1212.

[0166] Among the one or more components for contacting the circuit board 1201, at least one component for electrically connecting to the circuit board 1201 is included. The at least one component may include, for example, any one of the first supporting surface 1213 and the second supporting surface 1214. The third supporting surface 1215 may be electrically connected to the first supporting surface 1213, or may be insulated from the first supporting surface 1213. Similarly, the fourth supporting surface 1216 may be electrically connected to the second supporting surface 1214, or may be insulated from the second supporting surface 1214. In addition, when the third connecting surface 1218 contacts the third supporting surface 1215, the third supporting surface 1215 may be electrically connected to the third connecting surface 1218, or may be insulated from the third connecting surface 1218. When the fourth connecting surface 1219 contacts the fourth supporting surface 1216, the fourth supporting surface 1216 may be electrically connected to the fourth connecting surface 1219, or may be insulated from the fourth connecting surface 1219. Therefore, by setting the third connecting surface 1218 to contact and electrically connect with the third supporting surface 1215, and the fourth connecting surface 1219 to contact and electrically connect with the fourth supporting surface 1216, the current path between the first limiting surface 1211 and the second limiting surface 1212 can be increased, which is conducive to increasing the flexibility of adjusting the current flowing through the electrical connector.

[0167] The assembly relationship between the electrical connector 1202 and the circuit board 1201 is described below. The circuit board 1201 of the circuit assembly 1200 includes a groove 1203 for accommodating the first limiting surface 1211 of the electrical connector 1202. The first supporting surface 1213 and the second supporting surface 1214 of the electrical connector 1202 are fixed on one side of the circuit board 1201.

[0168] In summary, Fig.14 The circuit assembly 1000 shown is Fig.16The difference between the circuit components 1200 includes that the electrical connector 1202 does not include the first fixed end 641, the second fixed end 642, the third fixed end 643, and the fourth fixed end 644 of the electrical connector 600. In addition, the electrical connector 1202 fixes the second limiting surface 1212 on the circuit board 1201 through the first supporting surface 1213 and the second supporting surface 1214, and restricts the displacement between the first limiting surface 1211 and the second limiting surface 1212 through the third supporting surface 1215 and the fourth supporting surface 1216, thereby fixing the first limiting surface 1211 on the circuit board 1201.

[0169] For the circuit assembly 1000, it is necessary to additionally process the first insertion hole 1012 and the second insertion hole 1013 on the circuit board 1010 of the circuit assembly 1000, so as to fix the first fixed end 641 and the third fixed end 643 in the first insertion hole 1012, and fix the second fixed end 642 and the fourth fixed end 644 in the second insertion hole 1013. However, in general, compared with the method of fixing a part of the electrical connector on the side of the circuit board (hereinafter referred to as the side fixing method), the method of inserting and fixing a part of the circuit assembly into the hole of the circuit board (hereinafter referred to as the insertion fixing method) can obtain a relatively stronger fixing effect. When the fixing area occupied by the side fixing method is large, the same or better fixing effect as the insertion fixing method can be obtained. Therefore, relative to the electrical connector 1202, the electrical connector 600 can be more firmly fixed on the circuit board.

[0170] Fig.17 1 is a schematic diagram of an electrical connector and a circuit assembly equipped with the electrical connector provided in an embodiment of the present application. The circuit assembly 1300 includes a circuit board 1301 and an electrical connector 1302. The specific structure of the electrical connector 1302 is first described below.

[0171] Fig.14 The circuit assembly 1000 shown is Fig.17 The differences between the circuit assemblies 1300 include, Fig.17 The electrical connector 1302 is shown with Figure 6 (or Figure 7) include that the first connection surface 1315 of the electrical connector 1302 is fixed on the side of the first support surface 1313 close to the second limit surface 1312, and the second connection surface 1316 of the electrical connector 1302 is fixed on the side of the second support surface 1314 close to the second limit surface 1312. In addition, the first support surface 1313 can be electrically connected to the first connection surface 1315, and can be insulated from the first connection surface 1315. The second support surface 1314 can be electrically connected to the second connection surface 1316, and can be insulated from the second connection surface 1316. By setting the first support surface 1313 to contact and electrically connect with the first connection surface 1315, and the second support surface 1314 to contact and electrically connect with the second connection surface 1316, the current path between the first limit surface 1311 and the second limit surface 1312 can be increased, which is conducive to increasing the flexibility of adjusting the current flowing through the electrical connector.

[0172] On the one hand, the constraint force of the relative displacement between the first limiting surface 1311 and the second limiting surface 1312 can be strengthened, and the mechanical stability of the electrical connector 1302 can be strengthened. On the other hand, by setting the electrical connection or insulation between the first connecting surface 1315 and the first supporting surface 1313, multiple ways of current flowing through the electrical connector can be obtained. However, setting the first connecting surface 1315 to be fixed on the first supporting surface 1313 and the second connecting surface 1316 to be fixed on the second supporting surface 1314 will undoubtedly increase the processing difficulty and process complexity of the electrical connector.

[0173] Fig.18 14 is a schematic diagram of an electrical connector and a circuit assembly equipped with the electrical connector provided in an embodiment of the present application. The circuit assembly 1400 includes a circuit board 1401 and an electrical connector 1402. The specific structure of the electrical connector 1402 is first described below.

[0174] The electrical connector 1402 may include a first limiting surface 1411 and a second limiting surface 1412 arranged in parallel, and a bearing surface 1417 connected between the first limiting surface 1411 and the second limiting surface 1412. The bearing surface 1417 may be located on the same side of the first limiting surface 1411 and the second limiting surface 1412, and the bearing surface 1417 may be arranged perpendicularly relative to the first limiting surface 1411 and the second limiting surface 1412.

[0175] The electrical connector 1402 may further include a first extension arm 1421. The first extension arm 1421 is connected to the bearing surface 1417 and extends out of the cavity formed by the first limiting surface 1411, the second limiting surface 1412, and the bearing surface 1417. One end of the first extension arm 1421 away from the bearing surface 1417 includes an abutment area 1423. The abutment area 1423 is located outside the cavity formed by the first limiting surface 1411, the second limiting surface 1412, and the bearing surface 1417, and is used to abut against the frame of the electronic device, and the abutment torque of the frame acting on the abutment area 1423 is perpendicular to the circuit board.

[0176] The electrical connector 1402 may further include a first support surface 1413 and a second support surface 1414 for fixing on one side of the circuit board 1401. The first limiting surface 1111 is connected between the first supporting surface 1113 and the second supporting surface 1114. The plane where the first supporting surface 1413 is located may be located between the first limiting surface 1411 and the second limiting surface 1412, and the plane where the second supporting surface 1414 is located may be located between the first limiting surface 1411 and the second limiting surface 1412.

[0177] The electrical connector 1400 may further include a fifth supporting surface 1415 and a sixth supporting surface 1416. The fifth supporting surface 1415 may be connected to one end of the second limiting surface 1412 and fixed on the first supporting surface 1413, and the sixth supporting surface 1416 may be connected to the other end of the second limiting surface 1412 and fixed on the second supporting surface 1414. In addition, the plane where the fifth supporting surface 1415 is located may be located between the first supporting surface 1413 and the second limiting surface 1412, and the plane where the sixth supporting surface 1416 is located may be located between the second supporting surface 1414 and the second limiting surface 1412.

[0178] The one or more components for contacting the circuit board 1401 include at least one component for electrically connecting to the circuit board 1401. The at least one component may include, for example, any one of the first supporting surface 1413 and the second supporting surface 1414.

[0179] It should be noted that the first support surface 1413 can be electrically connected to the fifth support surface 1415, and can be insulated from the fifth support surface 1415. The second support surface 1414 can be electrically connected to the sixth support surface 1416, and can be insulated from the sixth support surface 1416. Therefore, by setting the first support surface 1413 to contact and electrically connect with the fifth support surface 1415, and the second support surface 1414 to contact and electrically connect with the sixth support surface 1416, the current path between the first limiting surface 1211 and the second limiting surface 1212 can be increased, which is conducive to increasing the flexibility of adjusting the current flowing through the electrical connector.

[0180] The assembly relationship between the electrical connector 1402 and the circuit board 1401 is described below. The circuit board 1401 of the circuit assembly 1400 includes a groove 1403 for accommodating the first limiting surface 1411 of the electrical connector 1402. The first supporting surface 1413 and the second supporting surface 1414 of the electrical connector 1402 are fixed on one side of the circuit board 1401.

[0181] It should be noted that Fig.18 The electrical connector 1402 is shown with Fig.17 The difference between the electrical connectors 1302 shown in the figure is that the electrical connector 1402 does not include the first fixed end 1341, the second fixed end 1342, the third fixed end 1343, and the fourth fixed end 1344 of the electrical connector 1302. The electrical connector 1402 fixes the second limiting surface 1412 on the circuit board 1401 through the first supporting surface 1413 and the second supporting surface 1414, and restricts the displacement between the first limiting surface 1411 and the second limiting surface 1412 through the fifth supporting surface 1415 and the sixth supporting surface 1416, so as to fix the first limiting surface 1411 on the circuit board 1401.

[0182] For the circuit assembly 1300, it is necessary to additionally process the first insertion hole 1304 and the second insertion hole 1305 on the circuit board 1301 of the circuit assembly 1300, so as to fix the first fixed end 1341 and the third fixed end 1343 in the first insertion hole 1304, and fix the second fixed end 1342 and the fourth fixed end 1344 in the second insertion hole 1305. However, compared with the method of fixing a part of the electrical connector to the side of the circuit board, the method of inserting and fixing a part of the circuit assembly into the hole of the circuit board can obtain a relatively stronger fixing effect. Therefore, compared with the electrical connector 1402, the electrical connector 1302 can be more firmly fixed on the circuit board.

[0183] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
