[0002] Beryllium copper alloy is a non-magnetic, wear-resistant, corrosion-resistant, high-strength alloy material. In communication equipment, springs made of beryllium copper alloy springs can increase the service life of the equipment. Because beryllium copper springs have a high degree of relaxation resistance and excellent wear resistance, they can ensure their compatibility with any contact surface. They will not burn or be affected by radiation. They are an alloy material with excellent performance. However, in antenna device technology, it is sometimes necessary to prepare equipment with both high strength and resilience. While fixing the components, resilience must also be provided so that the components can move within a certain range. The beryllium copper springs in the prior art lack resilience and cannot take into account both high strength and resilience, or have complex shapes and cumbersome assembly. How to use beryllium copper alloy to prepare a spring with both high strength and good resilience, adapt to different types of special-shaped rivets, and use it to fix some components of the antenna device, and ensure the overall stability and wear resistance of the component's force points, is a problem that urgently needs to be solved.

[0036] The application content is further explained below through the description of embodiments in conjunction with the accompanying drawings.

[0037] In a first aspect, this embodiment provides a combination accessory of an antenna device, such as Figure 6 and Figure 8 As shown, it includes a beryllium copper shrapnel 1, a special-shaped rivet 4 corresponding to the beryllium copper shrapnel 1, and a mounting base plate 2 and a transmission assembly 3 fixed by the beryllium copper shrapnel 1 and the special-shaped rivet 4. The combined accessory for the antenna device of the present application is a part of the antenna device, which is connected to other components of the antenna device (not shown in the figure) through the mounting base plate 2 and the transmission assembly 3. The transmission assembly can move relatively on the mounting base plate to realize signal reception or transmission of the antenna device. Through the combination of the beryllium copper shrapnel 1 and the special-shaped rivet 4, the wear of the connection part can be reduced when the transmission assembly moves while maintaining high strength.

[0038] like Figure 1 FIG. 1 is a schematic diagram of the overall structure of a beryllium copper shrapnel according to an embodiment of the present application. Figure 2 , which is a schematic diagram of the side structure of a beryllium copper shrapnel according to an embodiment of the present application.

[0039] In one embodiment, if Figure 1 to Figure 4 As shown, the beryllium copper shrapnel 1 comprises:

[0040] A supporting edge 11, wherein the supporting edge 11 cooperates with the special-shaped rivet 4 to fix the mounting base plate 2 and the transmission assembly 3;

[0041] A clamping portion 13, wherein a clamping through hole 131 is provided on the clamping portion 13, and a notch is provided around the clamping through hole so that the special-shaped rivet 4 can pass through the clamping through hole 131 to achieve a clamping connection; and

[0042] The elastic part 12 is connected to the supporting edge 11 and the clamping part 13 respectively, and the elastic part 12 is an arc-shaped structure, so that the beryllium copper spring has resilience, and the resilience here is perpendicular to the direction of the arc.

[0043] Specifically, Fig. 9As shown, the arc structure of the elastic part 12 is "S"-shaped, and the elastic part 12 includes a first arc 121 and a second arc 122 connected to one end of the first arc 121 and having an opposite arc, and the first arc 121 and the second arc 122 form the "S-shaped" structure as a whole.

[0044] Specifically, the other end of the first arc 121 is connected to the supporting edge 11, and the end of the second arc 122 away from the first arc 121 is connected to the clamping portion 13. Preferably, the elastic portion is integrally formed, and the beryllium copper elastic portion is also integrally formed.

[0045] Specifically, Figure 1 As shown, the elastic part is provided with a through groove extending along the arc structure to form a petal shape, that is, a petal-shaped through groove, so that the beryllium copper spring has both high strength and resilience.

[0046] Specifically, the petal-shaped through groove 123 includes:

[0047] A first through groove 1231 , wherein the first through groove 1231 is connected to the notch of the holding through hole 131 ; and

[0048] The second through slot 1232 is disposed between adjacent first through slots 1231 , and has an extension length shorter than that of the first through slot 1231 .

[0049] Specifically, the number of the first through slots 1231 and the second through slots 1232 are equal, and they are arranged one by one and symmetrically distributed. The symmetry here can be axial symmetry or central symmetry.

[0050] Preferably, if Figure 1 As shown, the number of the through slots 123 is 8, of which there are 4 first through slots 1231 and 4 second through slots 1232, which are spaced one by one to form an axisymmetric structure. Preferably, the 4 first through slots 1231 distributed at intervals are connected to the holding through hole 131, so that the holding through hole 131 forms a notch, and the 4 second through slots 1232 distributed at intervals are not connected to the holding through hole, so that a number of arc-shaped spring pieces are formed at the position between the petal-shaped through slots, and the petal-shaped spring pieces are elastic, so that the petal-shaped beryllium copper spring pieces have both fatigue resistance and high elasticity.

[0051] Preferably, the number of the petal-shaped through grooves can be 2 to 10, evenly and symmetrically distributed on the elastic part, and the petal-shaped through grooves are separated by a plurality of spring sheets. Different numbers and shapes of the petal-shaped through grooves will cause the overall resilience and strength of the elastic part to change, so that it can be suitable for special-shaped rivets with different structures.

[0052] In one embodiment, the elastic portion 12 includes a plurality of evenly distributed long through grooves, which are located at the position of the second arc 122 in the length direction and do not exceed the turning position of the first arc 121. Some of the long through grooves distributed at intervals are connected to the clamping through hole 131, and the extension length of the remaining long through grooves distributed at intervals is less than the through connection of the clamping through groove. The formed beryllium copper shrapnel has high strength, strong compressive resistance, high rigidity, and slightly weaker resilience than the petal-shaped beryllium copper shrapnel.

[0053] In one embodiment, the elastic portion 12 includes a first arc 121 and a second arc 122 and is a solid structure. The formed beryllium copper spring has high strength, strong compression resistance, high rigidity, and is not easy to rebound.

[0054] Since the beryllium copper shrapnel itself has high strength, if the hollow through-slot is not designed, the beryllium copper shrapnel has weak resilience and strong rigidity. Since the bottom limit end 41 of the special-shaped rivet 4 has a diameter larger than the clamping through-hole 131, the special-shaped rivet cannot pass through the clamping through-hole, and the purpose of fixing the bottom plate 2 and the transmission component 3 to form a combined accessory cannot be achieved. Therefore, the beryllium copper shrapnel 1 is designed with a through-slot, which can neutralize the strength and resilience of the beryllium copper shrapnel, so that the special-shaped rivet 4 can pass through the clamping through-hole 131, thereby fixing the bottom plate 2 and the transmission component 3 to form a combined accessory, and the resilience of the beryllium copper shrapnel 1 can also be adjusted.

[0055] Specifically, the support edge 11 is parallel to the holding through hole 131. In the assembled assembly, the support edge 11 contacts the bottom surface of the mounting base plate 2 to support the entire beryllium copper spring 1.

[0056] The present application also provides a special-shaped rivet 4, such as Figure 3 , is a schematic diagram of the structure of a special-shaped rivet in an embodiment of the present application, the special-shaped rivet comprises an integrally formed bottom limit end 41, a first column 42, a second column 43 and a top limit end 44; the cross-sectional diameter of the first column 42 is smaller than the cross-sectional diameters of the bottom limit end 41 and the second column 43, forming an annular groove; the cross-sectional diameter of the top limit end is larger than the cross-sectional diameter of the second column. Figure 4 and Figure 5 , which is a schematic diagram of the combined structure of a beryllium copper spring and a special-shaped rivet in one embodiment of the present application, in which the specific assembly position of the clamping portion 13 can be seen.

[0057] Specifically, Figure 4 and Figure 5As shown, the special-shaped rivet 4 is integrally formed, and the bottom limiting end 41, the first column 42, the second column 43 and the top limiting end 44 are fixedly connected. Although the diameter of the bottom limiting end 41 is larger than the diameter of the clamping through hole 131 of the beryllium copper spring 1, the clamping through hole 131 has a gap, so it has resilience, so that the bottom limiting end 41 can pass through the clamping through hole 131, and the clamping portion 13 is limited in the annular groove of the first column 42.

[0058] Preferably, the bottom limiting end 41 of the special-shaped rivet 4 is detachably connected to the first column 42 . The special-shaped rivet 4 of this embodiment is suitable for clamping a beryllium copper spring with a through hole that is a complete circle.

[0059] The shape of the clamping through hole 131 matches that of the annular groove. During assembly, due to the notch in the clamping through hole 131, the bottom limit end 41 can be stretched open and pass through the clamping through hole 131, so that the clamping portion 13 is clamped in the annular groove, thereby clamping and fixing the special-shaped rivet 4 and the beryllium copper spring 1.

[0060] The mounting base plate 2 includes a first through hole 21, the transmission assembly 3 includes a second through hole 31, the special-shaped rivet 4 passes through the second through hole 31, the first through hole 21 and the clamping through hole 131 in sequence, and is clamped and connected with the clamping through hole 131, and the mounting base plate 2 and the transmission assembly 3 are assembled to form the combined accessory. The first through hole 21 and the second through hole 31 are adapted to the second column 43 of the special-shaped rivet 4.

[0061] An embodiment of the present application provides a combination accessory of an antenna device, such as Figure 6 , Figure 7 As shown, Figure 6 An exploded view of a combination of components of an antenna device according to an embodiment of the present application is shown in FIG. Figure 7 The present invention is a schematic structural diagram of a combination accessory of an antenna device according to an embodiment of the present application. The combination accessory includes the beryllium copper spring 1 as described above, and also includes a mounting base plate 2, a transmission component 3 and a special-shaped rivet 4; the mounting base plate 2 and the transmission component 3 are connected to form the combination accessory through the special-shaped rivet 4 and the beryllium copper spring 1.

[0062] Specifically, the diameter of the top limiting end 44 is larger than that of the second column 43, and the diameter of the bottom limiting end 41 is larger than that of the clamping through hole 131, so that the mounting base plate 2 and the transmission assembly 3 are limited between the special-shaped rivet 4 and the beryllium copper shrapnel 1, and the movable range of the mounting base plate 2 and the transmission assembly 3 can be adjusted by setting the height of the first column 42 and the second column 43. Preferably, in the vertical direction, the sum of the heights of the second column 43 and the first column 42 is equal to the sum of the heights of the mounting base plate 2, the transmission assembly 3 and the beryllium copper shrapnel 1.

[0063] Preferably, the heights of the first column 42 and the second column 43 are adjustable, and the sum of the heights of the first column 42 and the second column 43 is adapted to the sum of the heights of the mounting base 2, the transmission assembly 3 and the beryllium copper shrapnel 1; the diameter of the first column 42 is adjustable and adapted to the diameters of the first through hole 21 and the second through hole 31; the diameter of the second column 43 is adjustable and adapted to the diameter of the clamping through hole 131.

[0064] During assembly, the special-shaped rivet 4 is sequentially passed through the second through hole 31 of the transmission assembly 3, the first through hole 21 of the mounting base plate 2, and then through the clamping through hole 131 of the beryllium copper shrapnel 1, so as to assemble into a combined accessory. Although the diameter of the bottom limit end 41 of the special-shaped rivet 4 is larger than the diameter of the clamping through hole 131, since the beryllium copper shrapnel 1 has a petal-shaped through groove 123, and the petal-shaped through grooves distributed at intervals are connected to 131, 131 is not a complete circle, but has an idle interval, which can be expanded under the action of external force to allow the special-shaped rivet 4 to pass through. The assembly method of the present application is simple and convenient.

[0065] Assembled components such as Figure 7 As shown, the supporting edge of the beryllium copper shrapnel 1 is connected to the bottom of the mounting base plate 2, and the clamping portion 13 of the beryllium copper shrapnel 1 is clamped in the first column 42 of the special-shaped rivet 4. The curvature of the second arc 122 does not exceed the height of the first column 42. Therefore, in the direction perpendicular to the special-shaped rivet 4, a receiving space is formed inside the beryllium copper shrapnel 1, which can provide a movable space for the first arc 121 and the second arc 122. The "S"-shaped structure formed by the connection of the first arc 121 and the second arc 122 makes the beryllium copper shrapnel 1 have both high strength and resilience.

[0066] Specifically, the arc angles of the two arc-shaped structures of the “S”-shaped structure can be adjusted to form beryllium copper springs 1 with different strengths and different resilience.

[0067] A second aspect of the present application is to provide an antenna device, comprising the aforementioned combination accessories of the antenna device.

[0068] In summary, the present application provides a combination accessory of an antenna device, including a beryllium copper shrapnel, a special-shaped rivet corresponding to the beryllium copper shrapnel, and a mounting base plate and a transmission assembly fixed by the beryllium copper shrapnel and the special-shaped rivet, wherein the beryllium copper shrapnel includes a supporting edge, the supporting edge and the special-shaped rivet cooperate to fix the mounting base plate and the transmission assembly; a clamping portion, the clamping portion is provided with a clamping through hole, and a notch is provided around the clamping through hole to pass the special-shaped rivet through the clamping through hole to achieve a clamping connection; and an elastic portion, the elastic portion is respectively connected to the supporting edge and the clamping portion, and the elastic portion is an arc structure, so that the petal-shaped beryllium copper shrapnel has resilience. The petal-shaped beryllium copper shrapnel of the present application is simple and convenient to assemble when assembled into a combination accessory for an antenna device, has strong adaptability, and has both high strength, good resilience and fatigue resistance, can ensure the stability of the force point at the installation connection, and effectively improve the service life and safety performance of the combination accessory.
