It can be seen that the back cover 360 and the middle frame 320 may be two different components, and the housing 120 of the electronic device 200 may be formed by assembling the back cover and the middle frame 320 together. The middle frame 320 includes a plurality of grooves for accommodating the power supply and the circuit board. As shown in FIG. 3 , a power supply 341 is provided in the first groove 331 , and a first circuit board 342 is provided in the second groove 332 .

Electronic components within electronic device 300 may be provided on circuit boards. In addition, the outer periphery 321 of the middle frame may serve as a part of the electronic components to realize part of the functions of the electronic components. For example, a part of the outer periphery 321 of the middle frame may serve as an antenna radiator of the antenna module, so as to realize the function of transmitting or receiving signals. As shown in FIG. 3 , the outer periphery 321 of the middle frame includes a first part 322 , a second part 323 , a third part 324 , a fourth part 325 , and a fifth part 326 , wherein the first part 322 , the third part 324 , and the fifth part 326 The materials of the second part 323 and the fourth part 325 are all conductor materials, and the materials of the second part 323 and the fourth part 325 are all insulating materials. The second part 323 adjoins 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 adjoins the third part 324 and the fifth part 326 to block the electrical connection The third portion 324 is electrically connected to the fifth portion 326 .

Thus, the first portion 322 can act as a first antenna radiator, the third portion 324 can act as a second antenna radiator, and the third portion 324 can act as a third antenna radiator.

As shown in FIG. 4 , the electronic device includes a display screen 410 , a housing 420 and a middle frame 430 . The casing 420 includes a side frame 421 and a back cover. The side frame 421 and the back cover are two parts of the housing 420 respectively. The side frame 421 is connected to the back cover, and the connection between the side frame 421 and the back cover cannot be divided normally. The material of the middle frame 421 may include conductive materials, such as metal materials. The middle frame 430 is accommodated in the 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 the power supply and the circuit board.

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 . Electronic components within electronic device 400 may be provided on circuit boards. In addition, the side frame 421 of the housing 420 may serve as a part of the electronic component to realize part of the functions of the electronic component.

The first part 422 and the third part 424 are adjacent to the two sides of the second part 423 respectively, so that the first part 422 and the third part 424 can block the second part 423 and the side frame 421 except the first part 422 , the second part 423 , the second part 424 , and the side frame 421 .

Thus, the second portion 423 may act as an antenna radiator.

As mentioned 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. FIG. 5 shows a schematic structural diagram of an electrical connector 530 disposed between the circuit board 510 and the frame 520 . The circuit board 510 may be the second circuit board 243 in FIG. 2 ; the circuit board 510 may also be the first circuit board 342 in FIG. 3 ; the circuit board 510 may also be the first circuit board 442 in FIG. 4 . The frame 520 may be the side frame 421 in FIG. 2 ; the frame 520 may also be the outer periphery 321 of the middle frame in FIG. 3 ; the frame 520 may also be the outer periphery 433 of the middle frame in FIG. 4 . As shown in FIG. 5 , 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 is electrically connected to the circuit board 510 . The electrical connector 530 includes an abutment area 531 , the abutment area 531 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 . By assembling the circuit board 510 , the frame 520 and the electrical connector 530 together, for example, an antenna module can be obtained. The circuit board 510 may feed power to the frame 520 through the electrical connector 530 , or realize the grounding of the frame 520 . The part of the frame 520 in contact with the abutting region 531 may be an antenna radiator in the antenna module. The radio frequency module of the antenna module may be disposed on the circuit board 510 . For example, the antenna module can implement functions such as 2G, 3G, 4G, NFC, Bluetooth, and WLAN.

The specific structure of the electrical connector will be described in detail below with reference to FIGS. 6 to 18 . It can be understood that the embodiments shown in FIG. 6 to FIG. 18 are only for helping those skilled in the art to better understand the technical solutions of the present application, rather than limiting the technical solutions of the present application.

FIG. 6 shows an electrical connector provided by an embodiment of the present application. The electrical connector 600 may be the electrical connector 510 in FIG. 5 . Observing the electrical connector 510 according to the direction indicated by the dashed arrow in FIG. 5 , a schematic structural diagram of the electrical connector as shown in FIG. 6 can be obtained. FIG. 7( a ) shows a front view of the electrical connector 600 , and FIG. 7( b ) shows a bottom view of the electrical connector 600 . The specific structure of the electrical connector 600 will be described below with reference to FIGS. 6 and 7 .

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 an arc 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 an arc surface or a corrugated surface. If any plane of the first limiting surface 611 perpendicular to the thickness direction is 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 parallel set.

The electrical connector 600 may further include a bearing surface 617 connected between the first limiting surface 611 and the second limiting surface 612 . 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 perpendicular 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 any plane of the first limiting surface 611 perpendicular to the thickness direction is perpendicular to 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 any plane of the second limiting surface 612 perpendicular to the thickness direction is perpendicular to 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 of.

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 first extension arm 621 is far away from the bearing surface 617 One end includes an abutment 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 for contacting the frame of the electronic device; the frame of the electronic device acts on the contact area The abutting moment of the 623 (the direction of the moment is shown by the moment M in FIG. 7 ) is perpendicular to the first support surface 613 , that is, perpendicular to the circuit board. The contact force exerted by the frame of the electronic device on the contact 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 moment of the frame of the electronic device acting on the abutment region 623 is perpendicular to the circuit board. That is to say, the moment acting on the electrical connector is perpendicular to the plane where the force arm and the force are located, so the electrical connector tends to rotate parallel to the circuit board, that is, the force arm should be located on the plane parallel to the circuit board.

It should be noted that "component A is connected to component B" includes that component A and component B are connected together and no other components are separated between component A and component B. It may also mean that component A and component B are connected together through component C.

It should be noted that "part 1 abuts on part 2", usually means that part 1 is in contact with part 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 uncontacted points is less than the second preset threshold; Condition 3: Within the maximum contour range of the contact surface, the area of the uncontacted surface is less than the third preset threshold. Through the contact of component 1 with component 2, current conduction can be achieved. However, if the area of the contact surface is too small, or the contact is not tight enough, and there may be a large number of uncontacted points in the contact surface, arcing is prone to occur, and the requirements for stable electrical connection cannot be met. In order to realize the abutment between the part 1 and the part 2, the contact force between the abutting region 623 and the frame of the electronic device should be greater than the fourth preset threshold.

It should be noted that the present application does not limit the specific shape of the contact area. The contact region 623 shown in FIG. 6 and FIG. 7 has a convex hull shape, such as a parabolic convex hull, an ellipsoidal convex hull, and a spherical convex hull. The abutment region 623 may also not include a convex hull.

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 abutting area 623 is used for abutting on the bearing surface 617 . That is to say, through the first extension arm 621 and the second extension arm 622, the bearing surface 617 can be electrically connected to the frame of the electronic device. It should be understood that in this application, in order to facilitate the division of the first extension arm 621 and the second extension arm 622, the second extension arm 622 may be regarded as being located on the first limiting surface 611, the second limiting surface 612, and the bearing surface The part of the first extension arm 621 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 contact area 623 .

It should be understood that the end of the second extension arm 622 away from the abutting area 623 is used to abut on the bearing surface 617, which may refer to the case where the electrical connector 600 is installed inside the electronic device (that is, the electrical connector 600 is in operation) state), the end of the second extending arm 622 away from the abutting area 623 abuts on the bearing surface 617 . In the case where the electrical connector 600 is not installed inside the electronic device (that is, the electrical connector 600 is in a free state), the end of the second extension arm 622 away from the abutting area 623 may not be in contact with the bearing surface 617, or may There is contact with the bearing surface 617 . It should be noted that, a possible situation requires electroplating on 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 abutting area 623 is not in contact with the bearing surface 617 , which can ensure that the surface of the second extension arm 622 is completely electroplated with a layer of film. When the electrical connector 600 is in a free state, the end of the second extension arm 622 away from the abutting area 623 is in contact with the bearing surface 617, so the part of the second extension arm 622 in contact with the bearing surface 617 cannot be electroplated , which may affect the electrical connection performance of the electrical connector. The partial enlarged view in FIG. 7 shows one possible situation where the electrical connector 600 has not been installed inside the electronic device. In this case, a gap A may exist between the second extension arm 622 and the bearing surface 617 .

The electrical connector 600 may include a first mounting lug 625 and a second mounting lug 626 . The first hanging lug 625 extends into the first hole 631 on the first limiting surface 611 . Therefore, the movable space of the first hanging lug 625 may be limited by the contour of the first hole 631 . The second hanging lugs 626 extend into the second holes 632 on the second limiting surface 612 . Therefore, the movable space of the second hanging lug 626 may be limited by the contour of the second hole 632 . By reasonably setting the sizes of the first hanging lugs 625 and the second hanging lugs 626 , the first hanging lugs 625 and the second hanging lugs 626 can be prevented from being separated from the first holes 631 and the second holes 632 . The first hanging lug 625 may be disposed on the first extension arm 621 , the abutment area 623 or the second extension arm 622 . Similarly, the second hanging lugs 626 may be disposed on the first extension arm 621 , the abutment area 623 or the second extension arm 622 . FIG. 6 shows an example in which the first hanging lug 625 and the second hanging lug 626 are both disposed on the second extending arm 622 .

The electrical connector 600 may further include a first support surface 613 and a second support surface 614 for contacting the circuit board and disposed on one side of the circuit board. The first support surface 613 and the second support surface 614 are located between the abutting area 623 and the bearing surface 617 . The first support surface 613 may be connected to the end of the first limiting surface 611 away from the first extension arm 621 (ie, close to the second extension arm 622 ), and the second support surface 614 may be close to the first limiting surface 611 One end of the extension arm 621 is connected. The plane where the first supporting surface 613 is located may be located between the first limiting surface 611 and the second limiting surface 612 , and the plane where the second supporting surface 614 is located may be located between the first limiting surface 611 and the second limiting surface 612 . between. Therefore, a part of the electrical connector 600 can be embedded in the circuit board, which is beneficial to reduce the space occupied by the electrical connector 600 (for example, reduce the space occupied by the electrical connector 600 in the thickness direction of the electronic device), so as to reduce the thickness of the electronic device , so as to meet the requirements for thinning and lightening of electronic devices. Optionally, the first limiting surface 611 may be arranged parallel to the first supporting surface 613 or the second supporting surface 614, so that the first limiting surface 611 may be arranged parallel to the circuit board. Optionally, the second limiting surface 612 may be arranged parallel to the first supporting surface 613 or the second supporting surface 614, so that the second limiting surface 612 may be arranged parallel to the circuit board.

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 (ie, fixed). In the case that 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 on the first support surface 613 (or the second support surface 614 ) On the circuit board; when 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 pass through the first support surface 613 (or the second support surface 614 ) 614) fixed on the circuit board. 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 on the circuit board .

It should be noted that, since there is a contact force between the contact area 623 and the frame of the electronic device, the contact force will generate torque on the portion of the electrical connector 600 that is in contact with the circuit board. That is, the contact force of the frame of the electronic device acting on the contact 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 of the contact 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 beneficial to reduce or even eliminate the contact force on the first support surface 613 , the moment generated by the second support surface 614 .

The electrical connector 600 may further include a first connection surface 615 and a second connection surface 616 . The first connecting surface 615 may be connected to an end of the second limiting surface 612 close to the first supporting surface 613 , and the second connecting surface 616 may be connected to an end of the second limiting surface 612 that is close to the second supporting surface 614 . Furthermore, the first connecting surface 615 may be located between the first supporting surface 613 and the second limiting surface 612 , and the second connecting surface 616 may be located between the second supporting surface 614 and the second limiting surface 612 . Optionally, both the first connecting surface 615 and the second connecting surface 616 may be disposed in parallel with the second limiting surface 612 .

It should be noted that, in this application, the limiting surface, the supporting surface, and the connecting surface are all surfaces. The plane on which the surface body is located may be any plane within the thickness range of the surface body and perpendicular to the thickness direction.

The electrical connector 600 may further include a first fixed end portion 641 , a second fixed end portion 642 , a third fixed end portion 643 and a fourth fixed end portion 644 . The first fixing end portion 641 , the second fixing end portion 642 , the third fixing end portion 643 and the fourth fixing end portion 644 can all be used to be inserted and fixed in the insertion holes of the circuit board. 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 connected. The third fixed end portion 643 may be connected to the end of the second limiting surface 612 close to the first support surface 613 ; the fourth fixed end portion 644 may be connected to the second limiting surface 612 close to the second support One end of the face 613 is connected. For example, the third fixed end portion 643 can be connected to the side of the first connecting surface 615 away from the second limiting surface 612 ; the fourth fixed end portion 644 can be connected to the side of the second connecting surface 616 that is far away from the second limiting surface 612 connected. In view of the contact force between the contact area 623 and the frame of the electronic device, the bearing surface 617 tends to be inclined and deformed due to the contact force. By fixing the first fixing end portion 641 , the second fixing end portion 642 , the third fixing end portion 643 and the fourth fixing end portion 644 on the circuit board, the first limiting surface 611 and the second limiting surface 612 can be constrained Movement occurs, thereby avoiding tilting of the bearing surface 617 .

Among the one or more components for contacting the circuit board, at least one component for electrically connecting with the circuit board is included.

In one example, the first fixed end portion 641 , the second fixed end portion 642 , the third fixed end portion 643 and the fourth fixed end portion 644 are all used for electrical connection with the 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 bearing surface 617 , the first extending arm 621 (or the second extending arm 622 ), and the abutting area 623 ; The circuit board can be electrically connected to the frame of the electronic device through the second fixed end portion 642, the first limiting surface 611, the bearing surface 617, the first extending arm 621 (or the second extending arm 622), and the abutting 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 bearing surface 617, the first extending arm 621 (or the second extending arm 622), and the abutting 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 bearing surface 617 , the first extending arm 621 (or the second extending arm 622 ), and the abutting region 623 .

In one example, the first support surface 613 and the second support surface 614 are both used for electrical connection with the circuit board. Then, the circuit board can be electrically connected to the frame of the electronic device through the first supporting surface 613, the first limiting surface 611, the bearing surface 617, the first extending arm 621 (or the second extending arm 622), and the abutting area 623; The circuit board can also be electrically connected to the frame of the electronic device through the first supporting surface, the second limiting surface 612 , the bearing surface 617 , the first extending arm 621 (or the second extending arm 622 ), and the abutting area 623 .

FIG. 8 shows four states of the electrical connector 600 . The four states may include state 1, state 2, state 3 and state 4. The state 1 may be the free state of the electrical connector 600 . State 2 , state 3 , and state 4 may all be working states of the electrical connector 600 . The spacing may be used to represent the spacing between the most distal end of the abutment region 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.

When the electrical connector 600 is in state 1, the electrical connector 600 has not been installed inside the electronic device, and the abutment area 623 of the electrical connector 600 may not abut on the frame of the electronic device. Therefore, when the electrical connector 600 is in state 1, the distance between the farthest end of the abutment region 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 abutting area 623 of the electrical connector 600 can abut on the frame of the electronic device.

When the electrical connector 600 is in state 2, the abutment area 623 of the electrical connector 600 just contacts 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 greater than the fifth pre-condition Set the threshold. That is, state 2 may represent the first critical operating state of the electrical connector 600 . In the 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 distance between the electrical connector 600 and the frame of the electronic device is the maximum allowable distance, that is, The distance between the electrical connector 600 and the frame of the electronic device cannot be greater than the maximum allowable distance, because if the distance between the electrical connector 600 and the frame of the electronic device is greater than the maximum allowable distance, the electrical connector 600 and the frame of the electronic device cannot be separated. stable contact.

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 is about to contact the frame of the electronic device, or the contact area 623 of the electrical connector 600 is The contact stress of 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. That is, state 4 may represent the second critical operating state of the electrical connector 600 . In the 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 distance between the electrical connector 600 and the frame of the electronic device is the minimum allowable distance, that is, The distance between the electrical connector 600 and the frame of the electronic device cannot be less than the minimum allowable distance, because if the distance between the electrical connector 600 and the frame of the electronic device is less than the minimum allowable distance, the electrical connector 600 and the frame of the electronic device cannot be stable contact.

The state 3 can be any state between the state 2 and the state 4, that is, the abutting area 623 of the electrical connector 600 presses the frame of the electronic device stably and firmly, and there is a gap between the electrical connector 600 and the frame of the electronic device. The spacing is greater than the minimum allowable spacing and less than the maximum allowable spacing.

It should be noted that, the electrical connector 600 is arbitrarily changed between the state 2, the state 3 and the state 4, and the second extension arm 622 is always in contact with the bearing surface 617. That is, when the electrical connector 600 is in any one of the state 2 , the state 3 and the state 4 , there is and only the second extension arm 622 is in stable contact with the bearing surface 617 .

The movable space of the first hanging lug 625 may be limited by the outline of the first hole 631, and when the electrical connector 600 is in any one of the state 2, the state 3 and the state 4, there may be two possible situations. : In one case, the first hanging lug 625 is always abutted on the contour of the first hole 631 stably; in another case, the first hanging lug 625 is not in contact with the contour of the first hole 631 all the time. If the first hanging lug 625 is always in stable contact with the contour of the first hole 631 , it can bear the contact force generated by a part of the contact area 623 contacting the frame of the electronic device. Similarly, the movable space of the second mounting lug 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 mounting lug 626 can always abut on the contour of the second hole 632 stably; or, the second hanging lug 626 can always not contact the contour of the second hole 632 . If the second mounting lugs 626 abut on the contour of the second hole 632 stably all the time, the contact force generated by a part of the abutting region 623 abutting against the frame of the electronic device can be supported.

It should be noted that, since there is a contact force between the contact area 623 and the frame of the electronic device, the contact force will generate a first moment on the first fixed end portion 641 , and the contact force will generate a contact force with the second fixed end portion 642 . The first moment is opposite to the second moment. In order to reduce the moment generated by the contact force on the part where the electrical connector 600 contacts the circuit board, the actual 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 contact area 623 and the first fixed end 641 , and the second distance is the distance between the contact area 623 and the second fixed end 642 . Similarly, in order to reduce the moment generated by the contact force on the part where the electrical connector 600 contacts the circuit board, the actual working state of the electrical connector 600 can be set to a third distance and a fourth distance, where the third distance is The distance between the contact area 623 and the third fixed end 643 , and the fourth distance is the distance between the contact area 623 and the fourth fixed end 644 . Then, when the electrical connector 600 is in state 1, the abutment area 623 may 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 may be relatively closer to the first fixed end 641 (or the third fixed end 643 ). That is to say, in the free state, the contact area 623 is relatively closer to the second fixed end 642 (or the fourth fixed end 644 ), and as the distance between the contact area 623 and the bearing surface 617 becomes smaller (For example, the abutting area is moved from the outside of the cavity formed by the first limit surface, the second limit surface and the bearing surface to the inside of the cavity), the abutment area 623 can be moved from closer to the second fixed end The position of the 642 (or the fourth fixed end 644 ) is moved to a position closer to the first fixed end 641 (or the third fixed end 643 ).

As shown in FIG. 9 , the embodiment of the present application further provides an electrical connector 700 . The difference between the electrical connector 700 and the electrical connector 600 shown in FIG. 6 (or FIG. 7 ) includes that the electrical connector 700 does not include the first hanging lugs 625 , the second hanging lugs 626 , the first Hole 631, second hole 632. That is, in the electrical connector 700 , the second extension arm 722 is not provided with the hanging ears, and the first limiting surface 711 and the second limiting surface 712 are not provided with holes for restricting the movement of the hanging ears. For the electrical connector 600, since the movable space of the first hanging lug 625 is constrained by the first hole 631, and the movable space of the second hanging lug 626 is constrained by the second hole 632, the abutting area 623 will not protrude excessively from the first hole 632. A cavity formed by a limiting surface 611 , a second limiting surface 612 and a bearing surface 617 . During transportation and installation of the electrical connector 600 , it is beneficial to avoid excessive bending of the first extension arm 621 in a direction away from the bearing surface 617 , thereby reducing the possibility of the electrical connector 600 being damaged. However, since the electrical connector 700 has no mounting ears and holes for restricting the movement of the mounting ears, the manufacturing process of the electrical connector 700 can be reduced or simplified. For example, for the electrical connector 600, it is necessary to control the positional tolerance between the first mounting lug 625 and the first hole 631, and the positional tolerance between the second mounting lug 626 and the second hole 632, so the processing of the electrical connector 700 The difficulty is lower than the processing difficulty of the electrical connector 600 . Under appropriate circumstances (for example, the material strength of the electrical connector is high, and it is difficult to change the angle of the first extension arm relative to the bearing surface), the electrical connector may not be provided with a hanging lug for restricting the movement of the abutting area and The hole used to constrain the movement of the mounting ear.

It should be noted that the electrical connector 600 shown in FIG. 6 (or FIG. 7 ) includes two mounting ears, and the electrical connector 700 shown in FIG. 9 does not include the mounting ears. Besides, the electrical connector may only include one hanging ear and a hole for constraining the hanging ear. For example, it includes the first mounting lug 625 of the electrical connector 600 and the first hole 631 for constraining the first mounting lug 625 , or includes the second mounting lug 626 of the electrical connector 600 and the second mounting lug 626 for constraining the second mounting lug 626 . A hole 632. In the case where the electrical connector only includes one hanging ear, the processing difficulty of 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 . between the electrical connectors 700 .

As shown in FIG. 10 , an embodiment of the present application further provides an electrical connector 800 . The difference between the electrical connector 800 and the electrical connector 700 shown in FIG. 9 includes that the electrical connector 800 does not include an extension arm abutting against the bearing surface 817 (ie, 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, only The electrical connection between the bearing surface 817 of the electrical connector 800 and the frame of the electronic device is achieved through the first extension arm 821 . For the electrical connector 700 , since current can pass through the first extension arm 721 and the second extension arm 722 , under the same voltage, the electrical connector 700 can transmit a higher current than the electrical connector 800 can transmit. In addition, since the second extending arm 722 can abut on the bearing surface 717 , the contact force that the abutting region 723 of the electrical connector 700 can withstand is higher than that that the abutting region 823 of the electrical connector 800 can withstand. contact force. As explained above, the greater the contact force, the better the avoidance of arcing. Therefore, compared with the electrical connector 800 , the electrical connector 700 is less likely to generate an arc phenomenon and is more likely to be in a stable working state. However, in order to ensure that the second extending arm 722 can stably abut on the bearing surface 717 , the difficulty of machining the electrical connector 700 is higher than that of machining the electrical connector 800 . Therefore, under suitable conditions (for example, the electrical connector needs to transmit less current, or the electrical connector bears a sufficiently large contact force), the electrical connector may not include an extension arm abutting against the bearing surface.

As shown in FIG. 11 , the embodiment of the present application further provides an electrical connector 900 . The difference between the electrical connector 900 shown in FIG. 11 and the electrical connector 600 shown in FIG. 6 (or FIG. 7 ) includes that the electrical connector 900 does not include the first connection surface 615 and the second connection of the electrical connector 600 . face 616. For the electrical connector 600, since the first connecting surface 615 and the second connecting surface 616 are located between the first supporting surface 613 or the second supporting surface 614 and the second limiting surface 612, the space occupied by the electrical connector 600 requires less space Less than the space occupied by the electrical connector 900 . Therefore, the electrical connector 600 can improve the flattening degree of the electronic device and improve the assembly compactness of the internal components of 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 and the second limiting surface 612 of the electrical connector 600 are (approximately) symmetrical, the first support The 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; ) is symmetrical, 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 connection 600 is higher than that of the electrical connection 900 . However, in order to form the connecting surface, it is necessary to process the connecting ribs between the connecting surface and the limit 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 . Under appropriate circumstances (for example, the electrical connector does not substantially affect the assembly method of the internal components of the electronic device, or the electrical connector has high mechanical stability), the electrical connector may not be provided on the electrical connector for example, in the electrical connector 600 . The first connection surface 615 and the second connection surface 616 of the .

As shown in FIG. 12 , the embodiment of the present application further provides an electrical connector 1500 . Compared with the electrical connector 600 shown in FIG. 6 or FIG. 7 , the electrical connector 1500 shown in FIG. 12 may include a first limiting lug 1533 and a second limiting lug 1534 .

The electrical connector 1500 may include a first limiting surface 1511 , 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 vertically disposed relative to the first limiting surface 1511 and the second limiting surface 1512 .

The electrical connector 1500 may also include a first extension arm 1521 . The first extending 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; the first extending arm 1521 is far away from the bearing surface One end of 1517 includes abutment 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 for contacting the frame of the electronic device; the frame of the electronic device acts on the contact area The abutment moment of the 1523 is perpendicular to the circuit board.

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

The electrical connector 1500 may also include a third extension arm 1524 . The third extension arm 1524 is connected to the abutment area 1523 . One end of the third extending arm 1524 away from the abutting area 1523 is located between the bearing surface 1517 and the first limiting lug 1533 , and is located between the bearing surface 1517 and the second limiting lug 1534 . The projected area of the third extending arm 1524 on the bearing surface 1517 partially overlaps with the projected area of the first limiting lug 1533 on the bearing surface 1517, and the projected area of the third extending arm 1524 on the bearing surface 1517 is the same as the projected area of the third extending arm 1524 on the bearing surface 1517 The projected areas of the second limiting lugs 1534 on the bearing surface 1517 partially overlap. Therefore, in the case of changing the extension angle of the third extension arm 1524 relative to the bearing surface 1517 , due to the existence of the first limiting lug 1533 and the second limiting lug 1534 , the third extending arm 1524 is close to the bearing surface 1517 . One end 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 extending arm 1524 away from the bearing surface 1517 is limited by the first limiting ears 1533 and the second limiting ears 1534 . One end of the third extension arm 1524 away from the abutting area 1523 may not be in contact with the bearing surface 1517 , or may be used to abut on the bearing surface 1517 .

The electrical connector 1500 constrains the third extension arm 1524 through the first limiting lug 1533 and the second limiting lug 1534; The second hole 632 , the first hanging lug 625 and the second hanging lug 626 constrain the second extending arm 622 . In the case where the third extension arm 1524 of the electrical connector 1500 may not be in contact with the bearing surface 1517 , the electrical connector 1500 can only realize the bearing surface 1516 of the electrical connector 1500 and the frame of the electronic device through the first extension arm 1521 electrical connection. In the electrical connector 600, the first extension arm 621 and the second extension arm 622 can be used to realize the electrical connection between the bearing surface 616 of the electrical connector 600 and the frame of the electronic device. Therefore, under the same voltage, the current that can be transmitted by the electrical connector 600 is higher than the current that can be transmitted by the electrical connector 1500 . In addition, since the second extension arm 622 can abut on the bearing surface 616 , the contact force that the abutting area 623 of the electrical connector 600 can bear is higher than that that the abutting area 1523 of the electrical connector 1500 can bear contact force. As explained above, the greater the contact force, the better the avoidance of arcing. Therefore, compared with the electrical connector 1500 , the electrical connector 600 is less likely to generate an arc phenomenon and is more likely to be in a stable working state.

Because the structures of the first limiting lug 1533 and the second limiting lug 1524 of the electrical connector 1500 are complex, the difficulty of processing the electrical connector 1500 is higher than that of the electrical connector 600 .

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

As shown in FIG. 13 , the embodiment of the present application further provides an electrical connector 1600 . Compared with the electrical connector 600 shown in FIG. 6 or FIG. 7 , the electrical connector 1600 shown in FIG. 13 may include a first hole (not shown in FIG. 13 ) for connecting with the first limiting surface 1611 out) and the fourth extension arm abutting against the second hole 1632 on the second limiting surface 1612. The electrical connector 1600 may include a first limiting surface 1611 , a second limiting surface 1612 arranged in parallel, 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 disposed relative to the first limiting surface 1611 and the second limiting surface 1612 .

The electrical connector 1600 may also include a first extension arm 1621 . The first extending 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; the first extending arm 1621 is far away from the bearing surface One end of 1617 includes abutment area 1623 . The abutting 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 abut on the frame of the electronic device; the frame of the electronic device acts on the abutting area The abutment moment of the 1623 is perpendicular to the circuit board.

The electrical connector 1600 may also include a first mounting lug (not shown in FIG. 13 ) and a second mounting lug 1626 . Wherein, the first hanging lug protrudes into the first hole on the first limiting surface 1611 (not shown in FIG. 13 ), the first hanging lug is used to abut on the contour of the first hole; the second hanging lug 1626 extends into In the second hole 1632 on the second limiting surface 1612 , the second hanging lug 1626 is used to abut on the contour of the second hole 1632 . That is to say, when the electrical connection 1600 is in the working state, the first mounting lug abuts on the contour of the first hole, and the second mounting lug 1626 abuts on the contour of the second hole 1632; and when the electrical connection 1600 is free In the state, the first hanging lug may or may not be in contact with the contour of the first hole, and the second hanging lug 1626 may or may not be in contact with the contour of the second hole 1632 . The first hanging ear and the second hanging ear 1626 may be disposed on the first extension arm 1621 , the abutment area 1623 or the fourth extension arm 1627 . FIG. 13 shows an example in which the first hanging lug and the second hanging lug 1626 are both disposed on the fourth extension arm 1627 .

The difference between the electrical connector 1600 shown in FIG. 13 and the electrical connector 600 shown in FIG. 6 (or FIG. 7 ) includes that the fourth extension arm 1627 of the electrical connector 1600 can not only withstand the reaction of the abutment area 1623 Moreover, the acting force of the first mounting lug on the first hole can generate a moment 1 on the part of the first support surface 1613 in contact with the circuit board, and the acting force of the second mounting lug 1632 on the second hole 1626 can exert a force on the second hole 1626. The portion of the support surface 1614 in contact with the circuit board generates a moment 2, and the moment 1 and the moment 2 can approximately cancel each other, thereby reducing the possibility of the bearing surface 1617 being inclined. Therefore, the electrical connector 1600 has stronger mechanical stability than the electrical connector 600 . However, in actual operation, the first extension arm 1621 may be deflected, and the force of the first mounting lug on the first hole is different from the acting force of the second mounting lug 1632 on the second hole 1626 . Therefore, the contact impedance between the first mounting lug and the first hole and the contact impedance between the second mounting lug 1632 and the second hole 1632 are different, which may affect the electrical connection performance of the electrical connector 1600 . Even if the first extension arm 1621 is severely deflected, only the first mounting lug is in contact with the first hole (ie, the second mounting lug 1632 is not in contact with the second hole 1626 ), or only the second mounting lug 1632 is in contact with the second hole 1626 is in contact (ie, the first hanging lug is not in contact with the first hole), then the electrical connection performance of the electrical connector 1600 is more likely to be affected.

Various configurations of electrical connectors are described above with reference to FIGS. 6-13 . Since the electrical connector 600 , the electrical connector 700 , the electrical connector 800 , the electrical connector 900 , the electrical connector 1500 , and the electrical connector 1600 are mounted on the circuit board in very similar ways, for simplicity of description, only electrical Taking the connector 600 as an example, an embodiment of mounting the electrical connector on the circuit board will be described in detail. Many modifications and other embodiments of the present applications will come to mind to one skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that this application is not limited to the specific embodiments disclosed.

Both the first support surface 613 and the second support surface 614 of the electrical connector 600 are in contact with one side of the circuit board 1010 . Optionally, both the first support surface 613 and the second support surface 614 are fixed on one side of the circuit board 1010 .

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 perpendicular to the first limiting surface 1111 and the second limiting surface 1112 .

The electrical connector 1102 may also 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 abutting 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 on the frame of the electronic device, and the frame acts on the abutting area The abutment moment of the 1123 is perpendicular to the circuit board.

The electrical connector 1102 further includes a first support surface 1113 and a second support surface 1114 for being fixed on 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 may 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 may be located between the first limiting surface 1111 and the second limiting surface 1112 . between.

The electrical connector 1102 may further include a third fixing end 1143 and a fourth fixing end 1144 for fixing on the circuit board 1101 . Wherein, the third fixed end portion 1143 can be connected with the end of the second limiting surface 1112 close to the first support surface 1113; the fourth fixed end portion 1144 can be connected with the second limiting surface 1112 close to the first support surface 1113 One ends of the two supporting surfaces 1113 are connected to each other.

The difference between the circuit assembly 1000 shown in FIG. 14 and the circuit assembly 1100 shown in FIG. 15 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 support surface 1113 and a second support surface 1114 for being fixed on the circuit board 1101 and disposed on one side of the circuit board 1101 . In addition, among the one or more components for contacting with the circuit board 1101 , at least one component for electrically connecting with the circuit board 1101 is included. The at least one component may include, for example, any one of the first support surface 1113 , the second support surface 1114 , the third fixed end portion 1143 and the fourth fixed end portion 1144 .

The following describes the assembly relationship between the electrical connector 1102 and the circuit board 1101 . The circuit board 1101 of the circuit assembly 1100 includes a groove 1103 for receiving the first limiting surface 1111 of the electrical connector 1102 .

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 support surface 1113 and the second support surface 1114 . Therefore, there are few ways to fix the electrical connector 1102, and the flexibility is relatively low, and it is difficult 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 the electrical connector 600 .

FIG. 16 is a schematic diagram of an electrical connector provided by an embodiment of the present application and a circuit assembly mounted with the electrical connector. Circuit assembly 1200 includes circuit board 1201 and electrical connectors 1202 . The specific structure of the electrical connector 1202 will be described below.

The electrical connector 1202 may include a first limiting surface 1211 , 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 .
