Thus, the first portion 222 may act as a first antenna radiator, the third portion 224 may act as a second antenna radiator, and the third portion 224 may act as a third antenna radiator.

As shown in fig. 3, the electronic device 300 includes a display screen 310, a rear 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 outer periphery 321 of the middle frame 320 (hereinafter, referred to as the middle frame outer periphery 321) may serve as a side frame of the electronic device, that is, the middle frame outer periphery 321 surrounds the outer periphery of the display screen 310 and surrounds the outer periphery of the rear cover 360, and the rear cover 360 and the display screen 310 are respectively located at two sides of the middle frame 320. It can be seen that the rear cover 360 and the middle frame 320 can be two different parts, and the housing 120 of the electronic device 200 can be formed by assembling the rear cover and the middle frame 320 together. The middle frame 320 includes a plurality of grooves for receiving power supplies and circuit boards. As shown in fig. 3, a power source 341 is disposed in the first recess 331, and a first circuit board 342 is disposed in the second recess 332. The power source 341 is electrically connected to the first circuit board 342 so that the power source 341 can supply power to the first circuit board 342. The electronic components within the electronic device 300 may be disposed on a circuit board. In addition, the middle frame outer periphery 321 may serve as a part of the electronic component to realize a partial function of the electronic component. For example, a portion of the middle frame periphery 321 may function as an antenna radiator of the antenna module to perform a function of transmitting or receiving a signal. As shown in fig. 3, the middle frame periphery 321 includes a first portion 322, a second portion 323, a third portion 324, a fourth portion 325, and a fifth portion 326, wherein the first portion 322, the third portion 324, and the fifth portion 326 are all made of a conductive material, and the second portion 323 and the fourth portion 325 are all made of an insulating material. The second portion 323 abuts both the first portion 322 and the third portion 324 to block the first portion 322 and the third portion 324 from being electrically connected; the fourth portion 325 abuts both the third portion 324 and the fifth portion 326 to block the third portion 324 from electrically connecting with the fifth portion 326. Electrical connections may be provided between first circuit board 342 and first portion 322, between first circuit board 342 and third portion 324, and between first circuit board 342 and fifth portion 326, respectively, first circuit board 342 may provide power to first portion 322, third portion 324, and fifth portion 326, respectively. Thus, the first portion 322 may act as a first antenna radiator, the third portion 324 may act as a second antenna radiator, and the third portion 324 may act as a third antenna radiator.

As shown in fig. 4, the electronic device includes a display screen 410, a housing 420, and a bezel 430. Wherein the housing 420 includes side frames 421 and a rear cover. The side frame 421 and the rear cover are two parts of the housing 420, respectively, the side frame 421 is connected to the rear cover, and the connection relationship between the side frame 421 and the rear cover cannot be generally divided. The material of the middle frame 421 may include a conductive material, such as a metal material. The middle frame 430 is accommodated in the cavity between the display screen 410, the side frames 421 and the rear cover. The middle frame 430 includes a plurality of grooves for receiving power and circuit boards. As shown in fig. 4, a power source 441 is provided in the first recess 431, and a first circuit board 442 is provided in the second recess 432. The power source 441 is electrically connected to the first circuit board 442 so that the power source 441 can supply power to the first circuit board 442. The electronic components within the electronic device 400 may be disposed on a circuit board. In addition, the side frame 421 of the housing 420 may serve as a part of the electronic component to realize a partial function of the electronic component. For example, as shown in fig. 4, the side frame 421 includes a first portion 422, a second portion 423, and a third portion 424, where the second portion 423 is made of a conductive material, and the first portion 422 and the third portion 424 are made of an insulating material. The first and third portions 422 and 424 are respectively adjacent to both sides of the second portion 423, so that the first and third portions 422 and 424 can block the second portion 423 from being electrically connected with other portions of the side frame 421 except for the first, second, and third portions 422, 423 and 424. In order to supply power to the second portion 423 of the side frame 421, an electrical connection member may be provided between the first circuit board and an outer periphery 433 of the middle frame 430 (hereinafter, referred to as a middle frame outer periphery 433), and the middle frame outer periphery 433 may be provided to be electrically connected to the case 420. Thus, the second portion 423 may act as an antenna radiator.

As described above, an electrical connection may be provided between the circuit board and the middle frame, or between the circuit board and the housing, to supply power to the housing of the electronic device. Fig. 5 shows a schematic structural diagram of an electrical connection 530 provided between the circuit board 510 and the bezel 520. Wherein 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. Bezel 520 may be side bezel 421 in FIG. 2; bezel 520 may also be the bezel perimeter 321 in FIG. 3; the bezel 520 may also be the middle bezel perimeter 433 in fig. 4. As shown in fig. 5, the circuit board 510 is located at 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 region 531, the abutment region 531 abutting on a side of the bezel 520 near the circuit board 510, such that the electrical connector 530 may be electrically connected between the circuit board 510 and the bezel 520. By assembling the circuit board 510, the frame 520, and the electrical connector 530, an antenna module can be obtained. Wherein the circuit board 510 can feed power to the frame 520 through the electrical connector 530 or realize grounding of the frame 520. The portion of the bezel 520 in contact with the abutment 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. The antenna module may implement, for example, 2G, 3G, 4G, NFC, bluetooth, WLAN, etc. functions.

The specific structure of the electrical connector is explained in detail below with reference to fig. 6 to 18. It should be understood that the embodiments shown in fig. 6 to 18 are only for helping those skilled in the art to better understand the technical solution of the present application, and are not intended to limit the technical solution of the present application.

Fig. 6 illustrates an electrical connector provided in accordance with an embodiment of the present application. Electrical connection 600 may be electrical connection 510 in fig. 5. Viewing electrical connector 510 from the direction indicated by the dashed arrow in fig. 5, a schematic structural view of the electrical connector 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 is described below with reference to fig. 6 and 7.

The electrical connector 600 may include a first position-limiting surface 611 and a second position-limiting surface 612 arranged in parallel. It should be understood that the first stopper surface 611 may be a curved surface. For example, the first limiting surface 611 may be a curved surface or a wave-shaped 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 wave-shaped 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, the first limiting surface 611 and the second limiting surface 612 can be considered to be arranged in parallel.

The electrical connector 600 may further include a bearing surface 617 coupled between the first retention surface 611 and the second retention 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 disposed vertically with respect to the first limiting surface 611 and the second limiting surface 612. It should be understood that the bearing surface 617 may be curved. For example, the bearing surface 617 may be a curved surface or a wavy 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, the first limiting surface 611 and the bearing surface 617 can be considered to be perpendicular to each other. Similarly, if any plane perpendicular to the thickness direction of the second limiting surface 612 is perpendicular to any plane perpendicular to the thickness direction of the bearing surface 617, the second limiting surface 612 and the bearing surface 617 can be considered to be perpendicular to each other.

The electrical connector 600 may also include a first extension arm 621. The first extension arm 621 is connected with the bearing surface 617 and extends out of a 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 distal from the seating surface 617 includes an abutment region 623. The abutting region 623 is located outside a cavity formed by the first limiting surface 611, the second limiting surface 612 and the bearing surface 617, and is used for abutting against a frame of the electronic device; the abutment moment (the direction of the moment is shown as moment M in fig. 7) of the frame of the electronic device acting on the abutment area 623 is perpendicular to the first support surface 613, i.e. perpendicular to the circuit board. The contact force of the frame of the electronic device acting on the contact area 623 is perpendicular to the contact surface 617. The first extension arm 621 can be approximately regarded as a moment arm disposed in parallel between the first position-limiting surface 611 and the second position-limiting surface 612. According to the direction of the force arm and the direction of the contact force, the contact moment of the frame of the electronic device acting on the contact area 623 is perpendicular to the circuit board. That is, the moment acting on the electrical connector is perpendicular to the moment arm and the plane in which the force lies, so that the electrical connector has a tendency to rotate parallel to the circuit board, i.e., the moment arm should lie in a plane parallel to the circuit board.

The phrase "the member a is connected to the member B" includes that the member a is connected to the member B without any other member interposed therebetween, and may also mean that the member a is connected to the member B via the member C.

Note that "the member 1 abuts on the member 2" generally means that the member 1 and the member 2 are in contact with each other; and satisfies at least one of the following conditions: condition 1: the area of the contact surface is larger than a first preset threshold value; condition 2: in the maximum outline range of the contact surface, the number of missed contacts is smaller than a second preset threshold value; condition 3: and within the maximum outline range of the contact surface, the area of the non-contact surface is smaller than a third preset threshold value. The current conduction can be achieved by the contact of the component 1 with the component 2. If the area of the contact surface is too small, or the contact is not tight enough, a large number of missed contacts can exist in the contact surface, the arc phenomenon is easy to occur, and the requirement of stable electric connection cannot be met. In order to achieve the abutment of component 1 with component 2, the contact force of the abutment area 623 with the bezel of the electronic device should be greater than a fourth preset threshold.

The present application does not limit the specific shape of the abutment region. The contact region 623 shown in fig. 6 and 7 has a convex hull shape, for example, a parabolic convex hull, an ellipsoidal convex hull, or 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 region 623. The end of the second extension arm 622 remote from the abutment region 623 is adapted to abut against the bearing surface 617. That is, the first extension arm 621 and the second extension arm 622 can electrically connect the supporting surface 617 to the frame of the electronic device. It should be understood that, in the present application, to facilitate dividing the first extension arm 621 and the second extension arm 622, the second extension arm 622 may be regarded as being located in a 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 leaning surface 617 can be regarded as the abutting region 623.

It should be understood that the end of the second extension arm 622 away from the contact area 623 is used for contacting against the bearing surface 617, which may mean that in a case where the electrical connector 600 is installed inside the electronic device (i.e. the electrical connector 600 is in an operating state), the end of the second extension arm 622 away from the contact area 623 contacts against the bearing surface 617. When the electrical connector 600 is not mounted 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 contact region 623 may not contact the bearing surface 617 or may contact the bearing surface 617. It is noted that one possible scenario may require electroplating of 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 region 623 is not in contact with the bearing surface 617, so that the surface of the second extension arm 622 can be completely plated with a film. When the electrical connector 600 is in a free state, one end of the second extension arm 622 away from the abutting region 623 is in contact with the bearing surface 617, and a portion of the second extension arm 622 in contact with the bearing surface 617 cannot be plated, so that the electrical connection performance of the electrical connector may be affected. The enlarged detail view in fig. 7 shows a possible case where the electrical connector 600 has not been mounted inside the electronic device. In this case, a gap a may exist between the second extending arm 622 and the bearing surface 617.

The electrical connector 600 may include a first tab 625 and a second tab 626. The first hanging lug 625 extends into the first hole 631 of the first position-limiting surface 611. Accordingly, the movable space of the first hanging lug 625 may be limited by the contour of the first hole 631. The second hanging lug 626 extends into the second hole 632 of the second limiting surface 612. Accordingly, the movable space of the second hanging lug 626 can be limited by the contour of the second hole 632. By properly sizing the first and second hangers 625, 626, the first hanger 625 and the second hanger 626 are prevented from being disengaged from the first hole 631 and the second hole 632, respectively. The first hangers 625 can be disposed on the first extension arm 621, the abutment region 623, or the second extension arm 622. Similarly, the second tab 626 can be disposed on the first extension arm 621, the abutment region 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 extension arm 622.

The electrical connector 600 may further include a first supporting surface 613 and a second supporting surface 614 for contacting the circuit board and disposed at one side of the circuit board. The first support surface 613 and the second support surface 614 are located between the abutment region 623 and the bearing surface 617. The first supporting surface 613 may be connected to an end of the first position-limiting surface 611 far from the first extension arm 621 (i.e., close to the second extension arm 622), and the second supporting surface 614 may be connected to an end of the first position-limiting surface 611 close to the first extension arm 621. The first supporting surface 613 may be located on a plane between the first limiting surface 611 and the second limiting surface 612, and the second supporting surface 614 may be located on a plane between the first limiting surface 611 and the second limiting surface 612. Therefore, a part of the electrical connector 600 may 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, thereby meeting the requirement of the electronic device for lightness and thinness. Optionally, the first position-limiting surface 611 may be disposed in parallel with respect to the first supporting surface 613 or the second supporting surface 614, so that the first position-limiting surface 611 may be disposed in parallel with respect to the circuit board. Alternatively, the second position-limiting surface 612 may be disposed in parallel with respect to the first supporting surface 613 or the second supporting surface 614, so that the second position-limiting surface 612 may be disposed in parallel with respect to the circuit board.

It should be noted that the contact relationship between the first supporting surface 613 (or the second supporting surface 614) and the circuit board includes a movable contact and a non-movable contact (i.e., a fixed contact). In the case that there is a movable contact relationship between the first supporting surface 613 (or the second supporting surface 614) and the circuit board, the electrical connector 600 is not fixed on the circuit board by the first supporting surface 613 (or the second supporting surface 614); in the case where there is an immovable contact relationship between the first supporting surface 613 (or the second supporting surface 614) and the circuit board, the electrical connector 600 may be fixed to the circuit board by the first supporting surface 613 (or the second supporting surface 614). It should be noted that, in the case that there is an immovable contact relationship between the first supporting surface 613 (or the second supporting 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, in view of the contact force between the contact area 623 and the frame of the electronic device, the contact force may generate a moment on the portion of the electrical connector 600 contacting the circuit board. I.e. the contact force of the frame of the electronic device acting on the abutment region 623 is located on the plane of the first support surface 613 (or the second support surface 614). In the case that the center position of the abutting region 623 is located on the plane of the first supporting surface 613 (or the second supporting surface 614) for contacting the circuit board, it is beneficial to reduce or even eliminate the moment generated by the contact force on the first supporting surface 613 and the second supporting surface 614.

The electrical connector 600 may also include a first connection face 615 and a second connection face 616. The first connecting surface 615 may be connected to an end of the second limiting surface 612 near the first supporting surface 613, and the second connecting surface 616 may be connected to an end of the second limiting surface 612 near the second supporting surface 614. Also, 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 the present application, the limiting surface, the supporting surface, and the connecting surface are all surface bodies. The plane of the surface body can 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 641, a second fixed end 642, a third fixed end 643, and a fourth fixed end 644. The first fixing end 641, the second fixing end 642, the third fixing end 643 and the fourth fixing end 644 can be used to be inserted into and fixed in the insertion hole of the circuit board. The first fixing end 641 may be connected to a side of the first supporting surface 613 away from the first limiting surface 611; the second fixing end portion 642 may be connected to a side of the second supporting surface 614 away from the first limiting surface 611. A third fixing end 643 can be connected to an end of the second limiting surface 612 close to the first supporting surface 613; a fourth fixed end 644 may be connected to an end of the second limiting surface 612 near the second supporting surface 613. For example, the third fixing end 643 can be connected to the side of the first connection surface 615 far away from the second limiting surface 612; the fourth fixed end 644 may be coupled to a side of the second coupling surface 616 that is distal from the second limiting surface 612. In view of the contact force between the contact region 623 and the bezel of the electronic device, the contact force tends to cause the contact surface 617 to be inclined or deformed. By fixing the first fixing end 641, the second fixing end 642, the third fixing end 643, and the fourth fixing end 644 on the circuit board, the first stopper surface 611 and the second stopper surface 612 can be restrained from moving, and the leaning surface 617 can be prevented from tilting.

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 fixing end 641, the second fixing end 642, the third fixing end 643 and the fourth fixing end 644 are used for electrical connection with a circuit board. Then, the circuit board may be electrically connected to the frame of the electronic device through the first fixing end 641, the first position-limiting surface 611, the supporting surface 617, the first extension arm 621 (or the second extension arm 622), and the abutting region 623; the circuit board can be electrically connected with the frame of the electronic device through the second fixing end portion 642, the first limiting surface 611, the bearing surface 617, the first extension arm 621 (or the second extension arm 622), and the abutting region 623; the circuit board may also be electrically connected to the frame of the electronic device through the third fixing end 643, the second limiting surface 612, the bearing surface 617, the first extension arm 621 (or the second extension arm 622), and the abutting region 623; the circuit board may be electrically connected to the frame of the electronic device through the fourth fixing end 644, the second limiting surface 612, the supporting surface 617, the first extension arm 621 (or the second extension 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 a circuit board. Then, the circuit board may be electrically connected to the frame of the electronic device through the first supporting surface 613, the first position-limiting surface 611, the supporting surface 617, the first extending arm 621 (or the second extending arm 622), and the abutting region 623; the circuit board may further be electrically connected to the frame of the electronic device through the first supporting surface, the second limiting surface 612, the supporting surface 617, the first extending arm 621 (or the second extending arm 622), and the abutting region 623.

Fig. 8 shows 4 states of the electrical connector 600. The 4 states may include state 1, state 2, state 3, state 4. Wherein state 1 may be a free state of electrical connector 600. State 2, state 3, and state 4 may all be the operational states of electrical connector 600. Spacing may be used to denote the spacing between the furthest end of the abutment region 623 from the seating surface 617 and the seating surface 617. Pitch 1, pitch 2, pitch 3, and pitch 4 correspond to state 1, state 2, state 3, and state 4, respectively. As can be seen, pitch 1> pitch 2> pitch 3> pitch 4.

With electrical connector 600 in state 1, electrical connector 600 has not yet been installed inside an electronic device, and abutment region 623 of electrical connector 600 may not abut against a bezel of the electronic device. Therefore, in the case where the electrical connector 600 is in the state 1, the distance between the farthest end of the abutment region 623 away from the seating surface 617 and the seating surface 617 is the largest. With electrical connector 600 in state 2, state 3, or state 4, electrical connector 600 is installed inside an electronic device and abutment region 623 of electrical connector 600 may abut against a bezel of the electronic device.

With electrical connector 600 in state 2, either the abutment area 623 of electrical connector 600 has just contacted the bezel of the electronic device or the contact stress of the abutment area 623 of electrical connector 600 with the bezel of the electronic device is greater than a fifth preset threshold. That is, state 2 may represent a first threshold operating state of electrical connector 600. In the first critical operating state, the electrical connector 600 may 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, i.e., the distance between the electrical connector 600 and the frame of the electronic device may not 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 may not be stably contacted.

When the electrical connector 600 is in the state 4, the first position-limiting surface 611 and/or the second position-limiting surface 612 of the electrical connector 600 are about to contact the frame of the electronic device, or the contact stress between the abutting area 623 of the electrical connector 600 and the frame of the electronic device is smaller than a sixth preset threshold, and the sixth preset threshold is larger than the fifth preset threshold. That is, state 4 may represent a second threshold operating state of electrical connector 600. In the second critical operating state, the electrical connector 600 may 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 may not be smaller than the minimum allowable distance, because if the distance between the electrical connector 600 and the frame of the electronic device is smaller than the minimum allowable distance, the electrical connector 600 and the frame of the electronic device may not be stably contacted.

State 3 may be any state between states 2 and 4, that is, the contact region 623 of the electrical connector 600 stably and tightly presses the bezel of the electronic device, and the distance between the electrical connector 600 and the bezel of the electronic device is greater than the minimum allowable distance and less than the maximum allowable distance.

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 contact surface 617. That is, when the electrical connector 600 is in any one of the state 2, the state 3, and the state 4, only the second extension arm 622 stably abuts against the bearing surface 617.

The movable space of the first hanger 625 may be limited by the contour of the first aperture 631, and with the electrical connector 600 in any of state 2, state 3, and state 4, there may be two possible situations: in one case, the first lug 625 always rests stably against the contour of the first hole 631; in another case, the first hangers 625 are not in contact with the contour of the first hole 631 at all times. If the first hanging lug 625 stably abuts on the contour of the first hole 631 at all times, a contact force generated by a part of the abutting area 623 abutting on the frame of the electronic device can be borne. Similarly, the movable space of the second hanging lug 626 can be limited by the contour of the second hole 632, and the second hanging lug 626 can always stably abut against the contour of the second hole 632 when the electrical connector 600 is in any one of the states 2, 3 and 4; alternatively, the second tab 626 may not always be in contact with the contour of the second hole 632. If the second hanging lug 626 is stably abutted against the contour of the second hole 632 at all times, a contact force generated by a part of the abutting area 623 abutting against the frame of the electronic device can be borne.

It should be noted that, in view of the contact force between the abutting region 623 and the frame of the electronic device, the contact force generates a first moment on the first fixing end 641, and the contact force generates a second moment on the second fixing end 642 in a direction opposite to the first moment. In order to reduce the moment generated by the contact force to the portion where the electrical connector 600 contacts the circuit board, the real operation state of the electrical connector 600 may be set to have a first distance that is the same as or approximately the same as a second distance that is the distance between the abutment region 623 and the first fixing end 641 and the second distance that is the distance between the abutment region 623 and the second fixing end 642. Similarly, in order to reduce the moment generated by the contact force on the portion of the electrical connector 600 contacting the circuit board, the real operating state of the electrical connector 600 may be set to a third distance and a fourth distance, wherein the third distance is the distance between the abutment region 623 and the third fixed end 643, and the fourth distance is the distance between the abutment region 623 and the fourth fixed end 644. Then, with the electrical connector 600 in state 1, the abutment region 623 may be relatively closer to the second fixing end 642 (or the fourth fixing end 644); with the electrical connector 600 in state 4, the abutment region 623 may be relatively closer to the first fixed end 641 (or the third fixed end 643). That is, in the free state, the abutment region 623 is disposed relatively closer to the second fixing end 642 (or the fourth fixing end 644), and as the distance between the abutment region 623 and the bearing surface 617 becomes smaller (for example, the abutment region is moved from outside to inside a cavity formed by the first stopper surface, the second stopper surface, and the bearing surface), the abutment region 623 may be moved from a position closer to the second fixing end 642 (or the fourth fixing end 644) to a position closer to the first fixing end 641 (or the third fixing end 643).

As shown in fig. 9, the present embodiment also 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 and second lugs 625, 626, and the first and second apertures 631, 632 of the electrical connector 600. That is, in the electrical connector 700, no lug is provided on the second extension arm 722, and no hole for restricting the movement of the lug is provided on the first limit surface 711 and the second limit surface 712. With respect to 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 region 623 does not extend beyond the cavity formed by the first limiting surface 611, the second limiting surface 612 and the bearing surface 617. During the transportation and installation of the electrical connector 600, it is beneficial to avoid the first extension arm 621 from bending excessively in the direction away from the bearing surface 617, so as to reduce the possibility of the electrical connector 600 being damaged. However, because electrical connector 700 does not have lugs and holes to restrain the movement of the lugs, the manufacturing process for electrical connector 700 may be reduced or simplified. For example, for electrical connector 600, it is desirable to control the positional tolerance between first tab 625 and first aperture 631, and the positional tolerance between second tab 626 and second aperture 632, and thus electrical connector 700 is less difficult to manufacture than electrical connector 600. Under appropriate circumstances (e.g., the electrical connector is made of a material having a high strength and the angle of the first extension arm relative to the bearing surface cannot be easily changed), the electrical connector may not be provided with a lug for restricting the movement of the abutment region and a hole for restricting the movement of the lug.

It should be noted that electrical connector 600 shown in fig. 6 (or fig. 7) includes two lugs, and electrical connector 700 shown in fig. 9 does not include a lug. In addition, the electrical connector may include only one lug and an aperture for restraining the lug. For example, including a first tab 625, such as electrical connector 600, and a first aperture 631 that receives the first tab 625, or including a second tab 626, such as electrical connector 600, and a first aperture 632 that receives the second tab 626. In the case where the electrical connector includes only one hanger, the difficulty of manufacturing the electrical connector is between electrical connector 600 and electrical connector 700; also, the difficulty of breaking the electrical connector is between electrical connector 600 and electrical connector 700.

As shown in fig. 10, the present embodiment also provides an electrical connector 800. A 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 the seating surface 817 (i.e., does not include the second extension arm 722 of the electrical connector 700). In the electrical connector 700, the bearing surface 717 of the electrical connector 700 can be electrically connected with the frame of the electronic device through the first extension arm 721 and the second extension arm 722; in the electrical connector 800, the bearing surface 817 of the electrical connector 800 can be electrically connected to the frame of the electronic device only 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, the electrical connector 700 can transmit a higher current than the electrical connector 800 can transmit at the same voltage. In addition, because second extension arm 722 can abut bearing surface 717, contact force that can be withstood by abutment region 723 of electrical connector 700 is higher than contact force that can be withstood by abutment region 823 of electrical connector 800. It has been stated above that a larger contact force is more advantageous for avoiding arcing phenomena. Therefore, the electrical connector 700 is less likely to generate arcing and is more likely to be in a stable operating state than the electrical connector 800. However, to ensure that the second extension arm 722 can stably abut against the seating surface 717, the difficulty of manufacturing the electrical connector 700 is greater than the difficulty of manufacturing the electrical connector 800. Thus, under appropriate conditions (e.g., the electrical connector needs to transmit less current, or the electrical connector is subjected to a sufficiently high contact force), the electrical connector may not include an extension arm that abuts the bearing surface.

As shown in fig. 11, the present embodiment also provides an electrical connector 900. The difference between electrical connector 900 shown in fig. 11 and electrical connector 600 shown in fig. 6 (or fig. 7) includes that electrical connector 900 does not include first connection face 615 and second connection face 616 of electrical connector 600. For the electrical connector 600, since the first connection surface 615 and the second connection 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 is smaller than the space occupied by the electrical connector 900. Therefore, the electrical connector 600 can improve the degree of flattening of the electronic device and improve the compactness of assembling components inside the electronic device. In addition, the symmetry of the electrical connector 600 is higher than that of the electrical connector 900, wherein in the case that the first position-limiting surface 611 and the second position-limiting surface 612 of the electrical connector 600 are (approximately) symmetrical, the first supporting surface 613 is (approximately) symmetrical to the first connecting surface 615, and the second supporting surface 614 is (approximately) symmetrical to the second connecting surface 616; under the condition that the first position-limiting surface 911 and the second position-limiting surface 912 of the electrical connector 900 are (approximately) symmetrical, the first supporting surface 913 and the second position-limiting surface 912 are asymmetrical, and the second supporting surface 914 and the second position-limiting surface 912 are asymmetrical. Thus, the mechanical stability of electrical connection 600 is higher than the mechanical stability of electrical connector 900. However, in order to mold the connecting surface, the connecting rib between the connecting surface and the limiting surface and the connecting rib between the connecting surface and the fixing end portion need to be processed, so that the processing difficulty of the electrical connector 900 is lower than that of the electrical connector 600. In some cases (e.g., the electrical connector does not substantially affect the assembly of the components inside the electronic device, or the mechanical stability of the electrical connector is high), the first connection surface 615 and the second connection surface 616 for the electrical connector 600 may not be provided on the electrical connector.

As shown in fig. 12, the embodiment of the present application further provides an electrical connector 1500. In contrast to the electrical connector 600 of FIG. 6 or FIG. 7, the electrical connector 1500 of FIG. 12 may include a first retention tab 1533 and a second retention tab 1534.

The electrical connector 1500 may include a first position-limiting surface 1511, a second position-limiting surface 1512, and a bearing surface 1517 connected between the first position-limiting surface 1511 and the second position-limiting surface 1512. The bearing surface 1517 may be located on the same side of the first position-limiting surface 1511 and the second position-limiting surface 1512, and the bearing surface 1517 may be disposed vertically with respect to the first position-limiting surface 1511 and the second position-limiting surface 1512.

The electrical connection 1500 can also include a first extension arm 1521. The first extension arm 1521 is connected with the bearing surface 1517 and extends out of a cavity formed by the first limiting surface 1511, the second limiting surface 1512 and the bearing surface 1517; the end of the first extension arm 1521 distal from the bearing surface 1517 includes an abutment region 1523. The abutting region 1523 is located outside a cavity formed by the first limiting surface 1511, the second limiting surface 1512 and the bearing surface 1517, and is configured to abut against a frame of the electronic device; the abutment moment of the bezel of the electronic device acting on the abutment region 1523 is perpendicular to the circuit board.

The electrical connector 1500 may also include a first retention tab 1533 and a second retention tab 1534. The first limit lug 1533 is connected with one side of the first limit surface 1511 far away from the bearing surface 1517; one end of the first position-limiting ear 1533 away from the first position-limiting surface 1511 extends toward the second position-limiting surface 1512. The second position-limiting lug 1534 is connected to a side of the second position-limiting surface 1512 away from the support surface 1517; one end of the second position-limiting ear 1534 away from the second position-limiting surface 1512 extends toward the first position-limiting surface 1511.

The electrical connection 1500 can also include a third extension arm 1524. The third extension arm 1524 is connected to the abutment region 1523. An end of the third extension arm 1524 away from the abutting region 1523 is located between the bearing surface 1517 and the first limit ear 1533, and between the bearing surface 1517 and the second limit ear 1534. The projected area of the third extension arm 1524 on the bearing surface 1517 partially coincides with the projected area of the first limit ear 1533 on the bearing surface 1517, and the projected area of the third extension arm 1524 on the bearing surface 1517 partially coincides with the projected area of the second limit ear 1534 on the bearing surface 1517. Therefore, in the case of changing the extending angle of the third extension arm 1524 relative to the bearing surface 1517, due to the existence of the first and second limiting ears 1533 and 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, second limiting surfaces 1511, 1512 and the bearing surface 1517. Thus, the space in which the third extension arm 1524 can move away from the bearing surface 1517 is limited by the first and second retention ears 1533 and 1534. The end of the third extension arm 1524 away from the abutment region 1523 may not contact the abutment surface 1517, but may also be configured to abut against the abutment surface 1517.

The electrical connector 1500 constrains the third extension arm 1524 via the first and second limiting ears 1533, 1534; the electrical connector 600 restricts the second extension arm 622 via the first position-limiting surface 611, the second position-limiting surface 612, the first hole 631, the second hole 632, the first hanging lug 625, and the second hanging lug 626. In the case that the third extension arm 1524 of the electrical connector 1500 may not contact the resting surface 1517, the electrical connector 1500 can only electrically connect the resting surface 1516 of the electrical connector 1500 to the bezel of the electronic device through the first extension arm 1521. In the electrical connector 600, the first extension arm 621 and the second extension arm 622 can electrically connect the bearing surface 616 of the electrical connector 600 with the frame of the electronic device. Thus, electrical connection 600 can transmit a higher current than electrical connection 1500 can transmit at the same voltage. In addition, since the second extension arm 622 can abut against the abutment surface 616, the contact force that can be borne by the abutment region 623 of the electrical connector 600 is higher than the contact force that can be borne by the abutment region 1523 of the electrical connector 1500. It has been stated above that a larger contact force is more advantageous for avoiding arcing phenomena. Therefore, the electrical connector 600 is less likely to generate an arc phenomenon and is more likely to be in a stable operation state, as compared to the electrical connector 1500.

Because the first and second retention tabs 1533 and 1524 of the electrical connector 1500 have complex structures, the difficulty of manufacturing the electrical connector 1500 is higher than the difficulty of manufacturing the electrical connector 600.

Assume that a distance between one side of the third extending arm 1524 close to the second limiting surface 1512 and one side of the third extending arm 1524 close to the first limiting surface 1511 is a distance 5, and a distance between one side of the second extending arm 622 close to the second limiting surface 612 and one side of the second extending arm 622 close to the first limiting surface 611 is a distance 6. With the pitch 5 being equal to the pitch 6, the first and second retention ears 1533 and 1534 of the electrical connector 1500 can strengthen the movable space of the third extension arm 1524 within the cavity formed by the first and second retention surfaces 611 and 612 and the bearing surface 617. Therefore, the electrical connector 1500 is less susceptible to damage during shipping and installation.

As shown in fig. 13, the present embodiment also provides an electrical connector 1600. In comparison to the electrical connector 600 shown in fig. 6 or 7, the electrical connector 1600 shown in fig. 13 may include a fourth extension arm for abutting against a first hole (not shown in fig. 13) on the first limiting surface 1611 and a second hole 1632 on the second limiting surface 1612. The electrical connector 1600 may include a first position-limiting surface 1611, a second position-limiting surface 1612, and a bearing surface 1617 connected between the first position-limiting surface 1611 and the second position-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 disposed perpendicularly to the first limiting surface 1611 and the second limiting surface 1612.

Electrical connection 1600 may also include a first extension arm 1621. Wherein, the first extension arm 1621 is connected with the bearing surface 1617 and extends out of a cavity formed by the first limit surface 1611, the second limit surface 1612 and the bearing surface 1617; the end of the first extension arm 1621 distal to the seating surface 1617 includes an abutment region 1623. The abutting area 1623 is located outside a cavity formed by the first limiting surface 1611, the second limiting surface 1612 and the bearing surface 1617 and is used for abutting against a frame of the electronic device; the abutment moment of the rim of the electronic device acting on the abutment area 1623 is perpendicular to the circuit board.

Electrical connector 1600 may also include a first tab (not shown in fig. 13) and a second tab 1626. Wherein the first hanging lug extends into a first hole (not shown in fig. 13) on the first position-limiting surface 1611, and the first hanging lug is used for abutting against the contour of the first hole; the second hanging lug 1626 extends into the second hole 1632 of the second limiting surface 1612, and the second hanging lug 1626 is used for abutting against the contour of the second hole 1632. That is, in the operative state of the electrical connection 1600, the first tab abuts against the contour of the first aperture and the second tab 1626 abuts against the contour of the second aperture 1632; while in the free state of the electrical connection 1600, the first tab may or may not contact the profile of the first aperture and the second tab 1626 may or may not contact the profile of the second aperture 1632. The first and second hangers 1626 may be disposed on the first extension arm 1621, the abutment region 1623, or the fourth extension arm 1627. Fig. 13 shows an example in which the first and second hanging lugs 1626 are provided 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 forces acting from the abutment region 1623; moreover, the acting force of the first hanging lug on the first hole can generate a moment 1 on the part of the first supporting surface 1613 contacting with the circuit board, the acting force of the second hanging lug 1632 on the second hole 1626 can generate a moment 2 on the part of the second supporting surface 1614 contacting with the circuit board, and the moment 1 and the moment 2 can approximately offset each other, so that the possibility that the bearing surface 1617 inclines is reduced. Therefore, electrical connector 1600 has greater mechanical stability than electrical connector 600. However, in practice, the first extension arm 1621 may deflect and the first suspension loop may exert a different force on the first hole than the second suspension loop 1632 does on the second hole 1626. Therefore, the contact resistance between the first tab and the first aperture and the contact resistance between the second tab 1632 and the second aperture 1632 are different, which may affect the electrical connection performance of the electrical connector 1600. Even more, if the first extension arm 1621 deflects significantly, resulting in only the first tab contacting the first aperture (i.e., the second tab 1632 does not contact the second aperture 1626), or only the second tab 1632 contacting the second aperture 1626 (i.e., the first tab does not contact the first aperture), it may be more likely to affect the electrical connection performance of the electrical connector 1600.

Electrical connections of various configurations are described above with respect to fig. 6-13. Since the manner of mounting electrical connectors 600, 700, 800, 900, 1500, 1600 on a circuit board is very similar, for simplicity of description, electrical connector 600 is used as an example only and the embodiment of mounting electrical connectors on a circuit board is described in detail. Many modifications and other embodiments of the disclosure will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the application is not limited to the specific embodiments disclosed.

Figure 14 is a schematic view of a circuit assembly with electrical connectors mounted therein according to an embodiment of the present application. Circuit assembly 1000 includes a circuit board 1010 and an electrical connector 600. The circuit board 1010 includes a groove 1011 for receiving the 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 fixed on one side of the circuit board 1010. The circuit board 1010 further includes a first insertion hole 1012 and a second insertion hole 1013. In this case, the first fixing end 641 (not shown in fig. 14) and the third fixing end 643 of the electrical connector 600 are inserted into and fixed to the first insertion hole 1012, and the second fixing end 642 (not shown in fig. 14) and the fourth fixing end 644 of the electrical connector are inserted into and fixed to the second insertion hole 1013.

Fig. 15 is a schematic view of an electrical connector and a circuit assembly mounted with the electrical connector provided in an embodiment of the present application. Circuit assembly 1100 includes circuit board 1101 and electrical connections 1102. The specific structure of electrical connector 1102 will be described.

The electrical connector 1102 may include a first position-limiting surface 1111, a second position-limiting surface 1112 arranged in parallel, and a bearing surface 1117 connected between the first position-limiting surface 1111 and the second position-limiting surface 1112. The bearing surface 1117 may be located on the same side of the first position-limiting surface 1111 and the second position-limiting surface 1112, and the bearing surface 1117 may be perpendicular to the first position-limiting surface 1111 and the second position-limiting surface 1112.

Electrical connection 1102 may also include a first extension arm 1121. The first extending arm 1121 is connected to the supporting surface 1117 and extends out of a cavity formed by the first limiting surface 1111, the second limiting surface 1112 and the supporting surface 1117. An end of the first extension arm 1121 distal from the seating surface 1117 includes an abutment region 1123. The abutting region 1123 is located outside a cavity formed by the first limiting surface 1111, the second limiting surface 1112 and the bearing surface 1117 and is used for abutting against a frame of the electronic device, and the abutting moment of the frame acting on the abutting region 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 securing to a 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 of the first supporting surface 1113 may be located between the first limiting surface 1111 and the second limiting surface 1112, and the plane of the second supporting surface 1114 may be located between the first limiting surface 1111 and the second limiting surface 1112.

The electrical connector 1102 may also include a third fixed end 1143 and a fourth fixed end 1144 for securing to the circuit board 1101. The third fixing end 1143 may be connected to an end of the second position-limiting surface 1112 close to the first supporting surface 1113; a fourth fixed end 1144 may be connected to an end of the second retaining surface 1112 adjacent to the second support surface 1113.

The difference between the circuit assembly 1000 shown in fig. 14 and the circuit assembly 1100 of fig. 15 includes that the electrical connector 1102 does not include the first and second fixed end portions 641, 642 of the electrical connector 600. The electrical connector 1102 includes a first support surface 1113 and a second support surface 1114 for fixing to the circuit board 1101 and provided on one side of the circuit board 1101. In addition, among the one or more components for making contact 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 bearing surface 1113, the second bearing surface 1114, the third fixed end 1143, and the fourth fixed end 1144.

The assembly of electrical connector 1102 to circuit board 1101 is described below. The circuit board 1101 of the circuit assembly 1100 includes a recess 1103 for receiving the first retaining surface 1111 of the electrical connector 1102. The first and second support surfaces 1113 and 1114 of the electrical connector 1102 are fixed on one side of the circuit board 1101. The circuit board 1101 further includes a first insertion hole 1104 and a second insertion hole 1105, wherein the third fixed end portion 1143 of the electrical connector 1102 is inserted into and fixed to the first insertion hole 1104, and the fourth fixed end portion 1144 of the electrical connector 1102 is inserted into and fixed to the second insertion hole 1105.

For the electrical connector 1102, the first position-limiting surface 1111 of the electrical connector 1102 can be fixed on the circuit board 1101 only by the first supporting surface 1113 and the second supporting surface 1114. Therefore, the manner of fixing the electrical connector 1102 is less, the flexibility is relatively low, and the stability of mounting the circuit assembly is not easily ensured. However, since the electrical connector 1102 omits the first and second fixed end portions 641 and 642 of the electrical connector 600, the difficulty of manufacturing the electrical connector 1102 is lower than that of manufacturing the electrical connector 600.

Fig. 16 is a schematic view of an electrical connector and a circuit assembly mounted with the electrical connector provided in an embodiment of the present application. Circuit assembly 1200 includes circuit board 1201 and electrical connection 1202. The specific structure of electrical connector 1202 is described below.

The electrical connector 1202 may include a first position-limiting surface 1211, a second position-limiting surface 1212, and a bearing surface 1217 connected between the first position-limiting surface 1211 and the second position-limiting surface 1212. The bearing surface 1217 may be located on the same side of the first position-limiting surface 1211 and the second position-limiting surface 1212, and the bearing surface 1217 may be disposed vertically with respect to the first position-limiting surface 1211 and the second position-limiting surface 1212.

The electrical connection 1202 may also include a first extension arm 1221. The first extension arm 1221 is connected to the support surface 1217 and extends out of a cavity formed by the first stop surface 1211, the second stop surface 1212, and the support surface 1217. The end of the first extension arm 1221 distal from the bearing surface 1217 includes an abutment region 1223. The abutting area 1223 is located outside a cavity formed by the first position-limiting surface 1211, the second position-limiting surface 1212, and the bearing surface 1217, and is configured to abut against a frame of the electronic device, where an abutting moment acting on the abutting area 1223 by the frame is perpendicular to the circuit board.

The electrical connector 1202 may further include a first support surface 1213 and a second support surface 1214 for being fixed to the circuit board 1201 and disposed on one side of the circuit board 1201. The second limiting surface 1212 is connected between the first supporting surface 1213 and the second supporting surface 1214. The first supporting surface 1213 may be located on a plane between the first position-limiting surface 1211 and the second position-limiting surface 1212, and the second supporting surface 1214 may be located on a plane between the first position-limiting surface 1211 and the second position-limiting surface 1212. The electrical connector 1202 also includes a third seating surface 1215, a fourth seating surface 1216. The first stop surface 1211 is connected between the third support surface 1215 and the fourth support surface 1216. The third supporting surface 1215 is fixed to the first supporting surface 1213 on a side thereof adjacent to the second limiting surface 1212, and the fourth supporting surface 1216 is fixed to the second supporting surface 1214 on a side thereof adjacent to the second limiting surface 1212. Optionally, the first support surface 1213 is electrically connected to the third support surface 1215.

Optionally, the electrical connector 1202 may further include a third connection surface 1218 coupled between the first support surface 1213 and the second retention surface 1212, and a fourth connection surface 1219 coupled between the second support surface 1214 and the second retention surface 1212. That is, the first supporting surface 1213 is connected to the second limiting surface 1212 through the third connecting surface 1218, and the second supporting surface 1214 is connected to the second limiting surface 1212 through the fourth connecting surface 1219. The third connecting surface 1218 may be located between the third supporting surface 1215 and the second limiting surface 1212, and the fourth connecting surface 1219 may be located between the fourth supporting surface 1216 and the second limiting surface 1212. Optionally, the third connection surface 1218 and the fourth connection surface 1219 may be disposed in parallel with respect to the second limiting surface 1212.

Among the one or more components for contacting the circuit board 1201, at least one component for electrically connecting with the circuit board 1201 is included. The at least one component may include, for example, any of the first support surface 1213 and the second support surface 1214. The third support surface 1215 may be electrically connected to the first support surface 1213 and may be insulated from the first support surface 1213. Similarly, the fourth support surface 1216 may be electrically connected to the second support surface 1214 and may also be insulated from the second support surface 1214. In addition, in the case where the third connection surface 1218 is in contact with the third support surface 1215, the third support surface 1215 may be electrically connected to the third connection surface 1218, or may be insulated from the third connection surface 1218. In the case where the fourth connecting surface 1219 is in contact with 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 disposing the third connecting surface 1218 to contact and electrically connect with the third supporting surface 1215, and disposing the fourth connecting surface 1219 to contact and electrically connect with the fourth supporting surface 1216, a current path between the first stopper surface 1211 and the second stopper surface 1212 can be increased, which is beneficial to increase flexibility of adjusting current flowing through the electrical connector.

The assembly relationship of 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 receiving the first stop surface 1211 of the electrical connector 1202. The first support surface 1213 and the second support surface 1214 of the electrical connector 1202 are fixed to one side of the circuit board 1201.

In summary, the differences between the circuit assembly 1000 shown in fig. 14 and the circuit assembly 1200 shown in fig. 16 include 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. The electrical connector 1202 fixes the second position-limiting surface 1212 to the circuit board 1201 via the first supporting surface 1213 and the second supporting surface 1214, and restricts the displacement between the first position-limiting surface 1211 and the second position-limiting surface 1212 via the third supporting surface 1215 and the fourth supporting surface 1216, thereby fixing the first position-limiting surface 1211 to the circuit board 1201.

In the circuit module 1000, it is necessary to additionally form a first insertion hole 1012 and a second insertion hole 1013 in the circuit board 1010 of the circuit module 1000, so that the first fixing end 641 and the third fixing end 643 are fixed in the first insertion hole 1012, and the second fixing end 642 and the fourth fixing end 644 are fixed in the second insertion hole 1013. However, since a relatively strong fixing effect can be obtained by inserting and fixing a part of the circuit assembly into the hole of the circuit board (hereinafter, referred to as an insertion fixing method) in comparison with a method of fixing a part of the electrical connector to a side surface of the circuit board (hereinafter, referred to as a side fixing method) in general. Under the condition that the side fixing mode occupies a larger fixing area, the fixing effect which is the same as or better than that of the plug-in fixing mode can be obtained. Therefore, electrical connector 600 can be more firmly fixed to the circuit board than electrical connector 1202.

Fig. 17 is a schematic view of an electrical connector and a circuit assembly mounted 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 will be described.

The difference between the circuit assembly 1000 shown in fig. 14 and the circuit assembly 1300 shown in fig. 17 includes that the electrical connector 1302 shown in fig. 17 is different from the electrical connector 600 shown in fig. 6 (or fig. 7) in that the first connecting surface 1315 of the electrical connector 1302 is fixed to a side of the first supporting surface 1313 close to the second limiting surface 1312, and the second connecting surface 1316 of the electrical connector 1302 is fixed to a side of the second supporting surface 1314 close to the second limiting surface 1312. In addition, the first supporting surface 1313 may be electrically connected to the first connection surface 1315, and may be insulated from the first connection surface 1315. The second supporting surface 1314 may be electrically connected to the second connecting surface 1316 and may be insulated from the second connecting surface 1316. By disposing the first supporting surface 1313 in contact with and electrically connected to the first connecting surface 1315, and the second supporting surface 1314 in contact with and electrically connected to the second connecting surface 1316, the current path between the first limiting surface 1311 and the second limiting surface 1312 can be increased, which is beneficial to increase the flexibility of adjusting the current flowing through the electrical connector.

In one aspect, the constraining strength of the relative displacement between the first and second limiting surfaces 1311, 1312 may be enhanced, and the mechanical stability of the electrical connector 1302 may be enhanced. On the other hand, by providing electrical connection or insulation between the first connection surface 1315 and the first support surface 1313, various ways of current flow through the electrical connector may be obtained. However, the first connection surface 1315 is fixed on the first support surface 1313, and the second connection surface 1316 is fixed on the second support surface 1314, which will increase the processing difficulty and complexity of the electrical connector.

Fig. 18 is a schematic view of an electrical connector and a circuit assembly mounted with the electrical connector provided by an embodiment of the present application. Circuit assembly 1400 includes a circuit board 1401 and an electrical connector 1402. The specific structure of the electrical connector 1402 is described below.

The electrical connector 1402 may include a first position-limiting surface 1411, a second position-limiting surface 1412 disposed in parallel, and a bearing surface 1417 connected between the first position-limiting surface 1411 and the second position-limiting surface 1412. The supporting surface 1417 may be located on the same side of the first position-limiting surface 1411 and the second position-limiting surface 1412, and the supporting surface 1417 may be disposed perpendicularly to the first position-limiting surface 1411 and the second position-limiting surface 1412.

The electrical connection 1402 may also include a first extension arm 1421. The first extension arm 1421 is connected to the support surface 1417 and extends out of a cavity formed by the first position-limiting surface 1411, the second position-limiting surface 1412 and the support surface 1417. The end of the first extension arm 1421 distal from the seating surface 1417 includes an abutment region 1423. The abutting region 1423 is located outside a cavity formed by the first position-limiting surface 1411, the second position-limiting surface 1412 and the bearing surface 1417, and is configured to abut against a frame of the electronic device, where an abutting moment acting on the abutting region 1423 by the frame is perpendicular to the circuit board.

The electrical connector 1402 may further include a first support surface 1413, a second support surface 1414 for securing to a 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 of the first supporting surface 1413 may be located between the first position-limiting surface 1411 and the second position-limiting surface 1412, and the plane of the second supporting surface 1414 may be located between the first position-limiting surface 1411 and the second position-limiting surface 1412.

The electrical connector 1400 may also include a fifth support surface 1415 and a sixth support surface 1416. The fifth supporting surface 1415 may be connected to one end of the second position-limiting surface 1412 and fixed to the first supporting surface 1413, and the sixth supporting surface 1416 may be connected to the other end of the second position-limiting surface 1412 and fixed to the second supporting surface 1414. Moreover, the plane of the fifth supporting surface 1415 may be located between the first supporting surface 1413 and the second position-limiting surface 1412, and the plane of the sixth supporting surface 1416 may be located between the second supporting surface 1414 and the second position-limiting surface 1412.

Among the one or more components for making contact with the circuit board 1401, at least one component for electrically connecting with the circuit board 1401 is included. The at least one component may include, for example, any one of the first support surface 1413, the second support surface 1414.

The first supporting surface 1413 may be electrically connected to the fifth supporting surface 1415, and may be insulated from the fifth supporting surface 1415. The second support surface 1414 may be electrically connected to the sixth support surface 1416 and may be insulated from the sixth support surface 1416. Therefore, by providing the first supporting surface 1413 in contact with and electrically connected to the fifth supporting surface 1415, and the second supporting surface 1414 in contact with and electrically connected to the sixth supporting surface 1416, the current path between the first position-limiting surface 1211 and the second position-limiting surface 1212 can be increased, which is beneficial to increasing the flexibility of adjusting the current flowing through the electrical connector.

The assembly of electrical connector 1402 to circuit board 1401 is described below. The circuit board 1401 of the circuit assembly 1400 includes a recess 1403 for receiving the first retention surface 1411 of the electrical connector 1402. The first 1413 and second 1414 support surfaces of the electrical connector 1402 are secured to one side of the circuit board 1401.

It should be noted that the difference between the electrical connector 1402 shown in fig. 18 and the electrical connector 1302 shown in fig. 17 includes 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 position-limiting surface 1412 to the circuit board 1401 via the first supporting surface 1413 and the second supporting surface 1414, and restricts the displacement between the first position-limiting surface 1411 and the second position-limiting surface 1412 via the fifth supporting surface 1415 and the sixth supporting surface 1416, so as to fix the first position-limiting surface 1411 to the circuit board 1401.

In the circuit assembly 1300, a first insertion hole 1304 and a second insertion hole 1305 must be additionally formed in the circuit board 1301 of the circuit assembly 1300 so that the first fixing end portion 1341 and the third fixing end portion 1343 are fixed in the first insertion hole 1304 and the second fixing end portion 1342 and the fourth fixing end portion 1344 are fixed in the second insertion hole 1305. However, the manner in which the part of the circuit assembly is inserted and fixed in the hole of the circuit board can obtain a relatively stronger fixing effect than the manner in which the part of the electrical connector is fixed to the side surface of the circuit board. Therefore, the electrical connector 1302 can be more firmly fixed to the circuit board than the electrical connector 1402.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
