[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0033] An embodiment of the present application provides a grounding ring. The grounding ring 10 is shown in Fig. 1. The grounding ring 10 is combined with a fixing member 31 to form a coaxial cable assembly 20, as shown in Fig. 5. Figure 1 Figure 6 ​​​The grounding ring 10 of the embodiment of the present application is used to connect two coaxial cables 21 together, so as to integrate the two coaxial cables 21 more compactly, and avoid the large space occupation caused by connecting one grounding ring to each coaxial cable 21. The two-in-one grounding ring 10 of the embodiment of the present application can save space.

[0034] As shown in Figure 1 and Figure 3 , in the embodiment, the grounding ring 10 comprises two arc-shaped parts 110 and a connecting part 120. The connecting part 120 is arranged between the two arc-shaped parts 110 and used to connect the two arc-shaped parts 110. Each arc-shaped part 110 is used to fix one coaxial cable 21, and the two arc-shaped parts 110 can fix two coaxial cables 21 at the same time. It can be understood that the diameter of the arc-shaped part 110 is consistent with the diameter of the coaxial cable 21, so that the arc-shaped part 110 can be wrapped around the outer periphery of the coaxial cable 21, and the coaxial cable 21 is better fixed.

[0035] As shown in Figure 1 , in the embodiment of the present application, each arc-shaped part 110 comprises a plurality of segments arranged along the axial direction, Figure 1 As shown in the embodiment, each arc-shaped part 110 comprises three segments, i.e. 110a, 110b and 110c. The arc-shaped part 110 arranged in the multi-segment structure can be in close contact with the coaxial cable 21, and the fitting stability is good, so that the grounding is more stable. The multi-segment structure makes the stress more evenly distributed, avoids the structural damage caused by stress concentration, and the multi-segment structure is more convenient to install and position. As shown in Figure 1 , the axial direction is Figure 1 Y direction shown in.

[0036] As shown in Figure 1 , at least one of the plurality of segments (110a, 110b, 110c) of the arc-shaped part 110 is provided with a spring sheet 111. The spring sheet 111 extends along the circumferential direction of the arc-shaped part 110 and opens outward. As shown in Figure 3 and Figure 5 , the outward opening of the spring sheet 111 makes the outer side of the spring sheet 111 protrude from the outer side wall of the arc-shaped part 110, so that the spring sheet 111 can abut against the external electronic equipment to realize fixation and grounding. As shown in Figure 7 and Figure 8 , the spring sheet 111 abuts against the groove wall of the electronic equipment mounting groove 311. As shown in Figure 7 and Figure 8 , when the grounding ring 10 is assembled with the coaxial cable 21 and the external electronic equipment, the outer side of the spring sheet 111 abuts against the electronic equipment (which can be understood as the fixing part 31), and the coaxial cable 21 is grounded; the inner side of the spring sheet 111 abuts against the coaxial cable 21, so as to tightly abut against the coaxial cable 21 and fix the cable.

[0037] In this embodiment, a spring piece 111 is provided on the arc-shaped portion 110. The spring piece 111 elastically abuts against the external electronic device and the coaxial cable 21. Due to the elasticity of the spring piece 111, it can adaptively adjust according to the size and shape of the coaxial cable 21, ensuring that the grounding ring 10 and the coaxial cable 21 always maintain a tight contact. This tight and stable contact can avoid phenomena such as electric sparks or arcs caused by poor contact, thereby reducing electromagnetic interference and signal noise. Furthermore, the spring piece 111 provides better vibration resistance to the grounding structure. When vibration occurs inside the electronic device or when the communication base station vibrates, the spring piece 111 can effectively absorb vibration energy, reducing the impact of vibration on grounding.

[0038] like Figure 3 As shown, two arc-shaped portions 110 are symmetrically arranged on both sides of the connecting portion 120 along a first direction, where the first direction is... Figure 1 and Figure 3 As shown in the X-direction, the first direction (X-direction) is perpendicular to the axial direction (Y-direction). Two arc-shaped portions 110 are formed by extending the connecting portion 120 along both sides. The two arc-shaped portions 110 first extend from both sides of the connecting portion 120 in a direction away from each other to form a semi-circular arc, and then extend in a direction closer to each other to form another semi-circular arc, thus forming a pair of embracing arc-shaped portions 110. Setting the arc-shaped portions 110 in an embracing manner as described above saves space. Furthermore, the embracing design facilitates the molding of the arc-shaped portions 110, allowing them to be integrally molded with the connecting portion 120.

[0039] like Figure 1 and Figure 3 As shown, the two arc-shaped portions 110 and the connecting portion 120 are integrally stamped and / or bent from the same metal sheet. Forming the connecting portion 120 and the arc-shaped portion 110 from a single metal sheet through processes such as stamping or bending improves the overall integrity of the grounding ring 10, reduces its size, and increases its strength.

[0040] like Figure 1 As shown, the spring piece 111 is also integrally stamped onto the curved portion 110. For example... Figure 5 As shown, the root 111a of the spring piece 111 is connected to the main body of the arc-shaped portion 110, the middle portion 111b of the spring piece 111 protrudes outward from the outer surface of the arc-shaped portion 110, and the end 111c of the spring piece 111 is bent inward. When the grounding ring 10 is assembled into the electronic device, as shown... Figure 8 As shown, the middle portion 111b of the arc-shaped part 110 is engaged in the mounting groove 311 of the electronic device. The groove wall of the mounting groove 311 presses against the spring piece 111, pushing the spring piece 111 towards the coaxial cable 21, thereby securing the spring piece 111 to the coaxial cable 21. Figure 5 and Figure 8As shown, since the end 111c of the spring piece 111 is bent inward, the groove wall of the mounting groove 311 presses the spring piece 111 against the coaxial cable 21, so that the spring piece 111 can fit well against the coaxial cable 21, clamping the cable and achieving a better fixing effect.

[0041] like Figure 1 As shown, when a spring piece 111 is stamped out on the arc-shaped portion 110 of the grounding ring 10, a hollow hole 112 is formed on the arc-shaped portion 110, and the spring piece 111 is formed in the hollow hole 112. Combined with... Figure 1 and Figure 5 The root 111a of the spring piece 111 is connected to the side wall of the hollow hole 112, and the middle part 111b and the end 111c of the spring piece 111 extend circumferentially along the arc-shaped part 110. Placing the spring piece 111 in the hollow hole 112 allows the spring piece 111 to have a larger deformation space.

[0042] As shown in the previous figure, the grounding ring 10 is made of a single piece of metal sheet by stamping. Therefore, the connecting part 120 is also formed by stamping. Figure 3 As shown, the connecting portion 120 is a recessed portion that is recessed between the two arc-shaped portions 110. In actual molding, the connecting portion 120 between the two arc-shaped portions 110 only needs to be stamped inward. Setting the connecting portion 120 as a recessed portion helps to make the arc-shaped portions 110 on both sides of the recess form an arc that fits the coaxial cable 21, making full use of the area between the two arc-shaped portions 110 and miniaturizing the grounding ring 10.

[0043] Combination Figure 1 and Figure 2 As shown, in each segment of the arc-shaped portion 110 equipped with spring pieces 111, spring pieces 111 are provided on both sides of each segment along the second direction. The second direction is... Figure 1 and Figure 2 The Z-direction shown can be understood as the second direction (Z-direction) being perpendicular to both the first direction (X-direction) and the axial direction (Y-direction). That is, the spring pieces 111 are arranged in pairs; each segment of the arc-shaped portion 110 with the spring pieces 111 has a pair of vertically opposite spring pieces 111 arranged vertically, as shown... Figure 5 As shown. Figure 8 This facilitates the contact of a pair of spring clips 111 against the two opposite sidewalls of the mounting slot 311.

[0044] Figure 9 and Figure 10 The diagram shows the structure of the grounding ring 10 before it is assembled with the coaxial cable 21 and before it is riveted into a ring shape. Figure 9 and Figure 10As shown, at this time, the two arc-shaped parts 110 are symmetrically distributed on both sides of the connecting part 120, roughly forming a W shape. Only the lower half of the arc-shaped part 110 is stamped out, that is, the lower half of the arc. After the coaxial cable 21 is inserted into the grounding ring 10, the upper half of the arc-shaped part 110 is stamped and rolled to form a complete arc shape, wrapping the coaxial cable 21.

[0045] refer to Figure 1 As described above, in this embodiment, each arcuate portion 110 includes three segments spaced apart along the axial direction: a first segment 110a, a middle segment 110b, and a third segment 110c. Spring tabs 111 are provided on the first segment 110a and the third segment 110c. (See reference...) Figure 6 When assembling the coaxial cable 21 with the grounding ring 10, the outer sheath 211 of the middle part of the coaxial cable 21 is peeled off to expose the shielding braided layer 212. For example... Figure 6 As shown, the middle section 110b of the arc-shaped portion 110 is connected to the shielding braided layer 212. Both middle sections 110b of the two arc-shaped portions 110 are connected to the shielding braided layer 212 of their respective coaxial cables 21, forming a unified ground potential. The first section 110a and the third section 110c of the arc-shaped portion 110 of the coaxial cable 21 are connected to the portions of the coaxial cable 21 with outer sheaths 211 at both ends. Spring clips 111 are disposed on the first section 110a and the third section 110c. Since the diameter of the shielding braided layer 212 of the coaxial cable 21 with its outer sheath 211 stripped is smaller, and the diameter of the portion without the outer sheath 211 stripped is larger, it is understandable that the diameter of the middle section 110b of the arc-shaped portion 110 is smaller than the diameter of the first section 110a and the third section 110c, thus ensuring that each section fits well against the coaxial cable 21.

[0046] In practical use, the coaxial cable 21 may be subjected to external forces such as pulling and bending. The three-section structure of the arc-shaped part 110 can better withstand these external forces and reduce structural damage caused by stress concentration. The three-section structure is also easier to position and align during installation. Compared with some complex-shaped or integral grounding rings 10, the three-section structure can be more easily fitted onto the coaxial cable 21, making installation easier for installers.

[0047] This application also provides a coaxial cable assembly 20. For example... Figure 6 As shown, the coaxial cable assembly 20 includes the aforementioned grounding ring 10 and a coaxial cable 21. The coaxial cable 21 is fixed in the arcuate portion 110 of the grounding ring 10. The specific assembly structure of the grounding ring 10 and the coaxial cable 21 is as described in the previous embodiment. Since the coaxial cable assembly 20 of this application embodiment uses the aforementioned grounding ring 10, it at least has the beneficial effects of the aforementioned grounding ring 10, which will not be repeated here.

[0048] This application also provides an electronic device. (See reference...) Figure 7 The electronic device includes the aforementioned coaxial cable assembly 20, and also includes a fastener 31 for securing the coaxial cable assembly 20. For example... Figure 7 and Figure 8 As shown, the fastener 31 has a mounting groove 311, and the coaxial cable assembly 20 passes through the mounting groove 311. Figure 8 As shown, the outer side of the grounding ring 10 spring contact 111 abuts against the groove wall of the mounting groove 311, and the inner side abuts against the coaxial cable 21. Since the electronic device of this embodiment employs the aforementioned coaxial cable assembly 20, it possesses at least the beneficial effects of the aforementioned coaxial cable assembly 20, which will not be repeated here.

[0049] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
