The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0043] Figure 1 This is a schematic diagram of a wire harness grounding clamp according to an exemplary embodiment. Figure 2 yes Figure 1 A schematic diagram of the grounding clamp for the center harness from another angle. (See diagram below.) Figure 1 and Figure 2 As shown, the wire harness grounding clamp includes a first assembly part 1, a second assembly part 2, a third assembly part 3, and a base plate 4. The base plate 4 includes a first side and a second side disposed opposite to each other. The first assembly part 1 extends upward from the first side of the base plate 4, and the first assembly part 1 is provided with a first elastic protrusion 11 protruding toward the center of the base plate 4, for example... Figure 1 As shown, the first elastic protrusion 11 can be located at the end of the first assembly part 1 away from the base plate 4, or in other embodiments, the first elastic protrusion 11 can also be located in the middle of the first assembly part 1, or at the end of the first assembly part 1 near the base plate 4, which can be designed as needed. The second assembly part 2 extends upward from the second side of the base plate 4, and the second assembly part 2 is provided with a second elastic protrusion 21 protruding toward the middle of the base plate 4, for example... Figure 1As shown, the second elastic protrusion 21 can be located at one end of the second assembly part 2 away from the base plate 4, or in other embodiments, the second elastic protrusion 21 can also be located in the middle of the second assembly part 2, or at one end of the second assembly part 2 near the base plate 4, and can be designed as needed.

[0044] Thus, the base plate 4, the first assembly part 1, and the second assembly part 2 can form a wire harness assembly cavity 5. Subsequently, the RF wire harness can enter the wire harness assembly cavity 5 through the gap between the first assembly part 1 and the second assembly part 2, after being pried open by a certain force by the first elastic protrusion 11 and the second elastic protrusion 21. Figure 2 As shown, the first elastic protrusion 11 and the second elastic protrusion 21 elastically abut against the grounding ring of the RF harness. Compared to the "hard-to-hard" contact method, the elastic contact method in this disclosure can improve the stability and reliability of the electrical contact, and facilitates the conduction of noise from the outer shielding layer of the RF harness to the harness grounding clamp through the grounding ring, and then into the ground. For example, Figure 1 As shown, the first elastic protrusion 11 and the second elastic protrusion 21 can be symmetrically arranged, which is beneficial to improving the connection stability of the RF harness. In other embodiments, the first assembly part 1 and the second assembly part 2 can also be asymmetrically arranged. For example, the direction from the first side to the second side can be taken as the first direction, and the direction perpendicular to the first direction can be taken as the second direction, and the second direction is parallel to the plane of the base plate 4. In this second direction, the first assembly part 1 and the second assembly part 2 can be spaced apart, which is beneficial to maintaining the orientation of the RF harness along its length.

[0045] In some embodiments, the first assembly part 1 may include a first elastic arm, the first elastic arm portion bending and protruding towards the center of the base plate 4 to form a first elastic protrusion 11. The second assembly part 2 may include a second elastic arm, the second elastic arm portion bending and protruding towards the center of the base plate 4 to form a second elastic protrusion 21. The design of the first and second elastic arms provides more deformation space for the first assembly part 1 and the second assembly part 2, reducing the assembly difficulty of the RF harness. In other embodiments, the first assembly part 1 may include a first upright plate, and the first elastic protrusion 11 may be a bent hollow structure disposed on the first upright plate. The second assembly part 2 may include a second upright plate, and the second elastic protrusion 21 may be a bent hollow structure disposed on the second upright plate. The specific structure of the first assembly part 1 and the second assembly part 2 can be designed as needed, and this disclosure does not impose any limitations on this design.

[0046] The third assembly part 3 is connected to the base plate 4, and the third assembly part 3 is provided with a third elastic protrusion 31 protruding from the back of the wire harness assembly cavity 5. Subsequently, the third elastic protrusion 31 elastically abuts against the ground of the electronic device on which the wire harness grounding clamp is disposed, so that the electrical signal introduced into the wire harness grounding clamp is introduced into the ground. For example, still taking... Figure 1 As shown, the base plate 4 includes a third side connecting the first side and the second side. In some embodiments, such as... Figure 1 and Figure 2 As shown, the third assembly part 3 includes a third elastic arm, which bends from the third side to below the base plate 4, and the third elastic arm portion bends and protrudes in a direction away from the base plate 4, thereby forming a third elastic protrusion 31. Subsequently, when the grounding wire harness clamp is assembled to the electronic device, the third elastic protrusion 31 deforms under the action of the assembly force to achieve elastic contact. Of course, the third assembly part 3 can also be disposed on the first side or the second side and bent to below the base plate 4, or in some other embodiments, the third assembly part 3 can also be disposed on the first side, the second side, or the third side, and the third assembly part 3 extends upward relative to the base plate 4, and the protrusion direction of the third elastic protrusion 31 is opposite to the protrusion direction of the first elastic protrusion 11 and the second elastic protrusion 21.

[0047] Furthermore, the third elastic protrusion 31 can make elastic contact with the floor of the electronic device. In some embodiments, the third assembly part 3 also includes an elastic protrusion 32 disposed on the side of the third elastic protrusion 31 away from the base plate 4. Subsequently, the elastic protrusion 32 can make elastic contact with the floor of the electronic device, thereby reducing the contact area, reducing friction, and helping to reduce the wear of the wire harness grounding clip. The elastic protrusion 32 can include a top 321 and an extension 322 extending arcuately from the top 321 to the third elastic protrusion 31. The elastic protrusion 32 can be formed by the third elastic protrusion 31 being recessed in the direction away from the base plate 4, or it can be a hollow structure connected to the third elastic protrusion 31. The arcuate design can reduce the sharp edges of the protrusion 32, reducing the probability of damage during transportation, and also reducing the probability of the elastic protrusion 32 scratching the floor.

[0048] In other embodiments, such as Figure 3 As shown, the third mounting part 3 is the third elastic protrusion 31 itself. This third elastic protrusion 31 is connected to one side of the base plate 4 behind the wire harness assembly cavity 5. To achieve elastic contact, the third elastic protrusion 31 is hollow, which simplifies the structure of the wire harness grounding clamp compared to the third elastic arm design. In some other embodiments, such as... Figure 4 As shown, the third mounting part 3 also includes a mounting plate 33, which is arranged parallel to the base plate 4, and the third elastic protrusion 31 is connected to the side of the mounting plate 33 away from the base plate 4.

[0049] In the above embodiments, the base plate 4 further includes a fourth side disposed opposite to the third side, and the wire harness grounding clamp further includes a bending portion 6, which extends from the fourth side of the base plate 4 and bends to the bottom of the base plate 4, and is disposed parallel to the base plate 4. Based on the design of the bending portion 6, when the third assembly part 3 contacts the floor of the electronic device, the bending portion 6 fills the space gap between the fourth side of the base plate 4 and the floor, which helps to avoid uneven placement of the grounding wire harness clamp.

[0050] In the technical solution disclosed herein, the wire harness grounding clamp can form a complete signal grounding path through the elastic contact between the first elastic protrusion 11 and the second elastic protrusion 21 and the radio frequency wire harness, and the elastic contact between the third elastic protrusion 31 and the ground. Furthermore, the elastic contact can improve the stability and reliability of the electrical contact.

[0051] In the above embodiments, such as Figures 1-4 As shown, the wire harness grounding clamp also includes a first metal wall 7 and a second metal wall 8. Both the second metal wall 8 and the first metal wall 7 extend upward from the first side of the base plate 4. A first assembly part 1 is located between the first metal wall 7 and the second metal wall 8, and the first assembly part 1 is positioned near the center of the base plate 4 relative to the first metal wall 7 and the second metal wall 8. Based on this, the wire harness grounding clamp can be limited in the extending direction on the first side through contact between the first metal wall 7 and the second metal wall 8 and other structures of the electronic device.

[0052] Similarly, the wire harness grounding clamp also includes a third metal wall 9 and a fourth metal wall 10, both of which extend upward from the first side of the base plate 4. A second assembly portion 2 is located between the third metal wall 9 and the fourth metal wall 10, and is positioned near the center of the base plate 4 relative to the third metal wall 9 and the fourth metal wall 10. Based on this, the wire harness grounding clamp can be subsequently limited in its extending direction on the first side through contact between the third metal wall 9 and the fourth metal wall 10 and other structures of the electronic device.

[0053] Based on the technical solution disclosed herein, such as Figures 5-7As shown, an electronic device is also provided, comprising a metal frame 101, a wire harness grounding clip as described in any of the above embodiments, and a radio frequency (RF) wire harness 102. The metal frame 101 includes a clearance groove 103, in which the wire harness grounding clip can be disposed. A third elastic protrusion 31 elastically abuts against the inner wall of the clearance groove 103, for example, against the bottom wall of the clearance groove 103. The RF wire harness 102 includes a wire harness body 104 and a grounding ring 105. The grounding ring 105 is sleeved on the outside of the wire harness body 104 and disposed within the wire harness assembly cavity 5. A first elastic protrusion 11 and a second elastic protrusion 21 elastically abut against the grounding ring 105. Based on this, the metal frame 101 can be used as ground to guide clutter from the outer shielding layer of the wire harness body 104 into the metal frame 101, reducing the impact of the wire harness body 104 on the antenna performance of the electronic device.

[0054] Furthermore, the metal frame 101 also includes a limiting cavity 106 communicating with the clearance groove 103. The wire harness grounding clamp includes a first metal wall 7 and a second metal wall 8 spaced apart along the length direction of the RF wire harness 102. The first metal wall 7 and the second metal wall 8 are both at least partially located within the limiting cavity 106 and respectively abut against the inner wall of the limiting cavity 106 perpendicular to the length direction of the RF wire harness 102. In this way, the wire harness grounding clamp can be stably limited within the clearance groove 103, reducing the risk of displacement of the wire harness grounding clamp during the assembly of the RF wire harness 102.
