Description

Technical Field

[0001] This invention belongs to the field of antenna technology, and specifically relates to an antenna vibrator assembly. Background Technology

[0002] With the steady growth of the wireless network market, various wireless applications have emerged. Antennas, as key components in these wireless systems, play a crucial role in radiating high-frequency signals as electromagnetic waves or receiving electromagnetic waves from space at the radio frequency front end. Antenna elements are important components in antennas, functioning to guide and amplify electromagnetic waves to enhance the electromagnetic signals received by the antenna; therefore, they are widely used in various types of antennas. Existing elements are all made of metal rods, which cannot be bent. Excessive bending angles can damage the element and affect the antenna's performance. For antennas that require frequent installation, removal, and relocation, existing elements are easily damaged and inconvenient to carry. Summary of the Invention

[0003] This invention addresses the technical problems of existing technologies, such as easy damage after bending and inconvenience in carrying, by providing an antenna vibrator assembly. The vibrator assembly uses a cable as its main body and can still be used normally after being bent 90 degrees multiple times, making it convenient to carry.

[0004] The technical solution adopted in this invention is: an antenna vibrator assembly, including a cable and a connector assembly, wherein the cable is divided into a non-metallic part and a metallic part, the metallic part is connected to the connector assembly, and a conductive layer is disposed inside the metallic part.

[0005] Furthermore, the metal portion includes a wire core and a liner, a conductive layer, a non-metallic braided layer, and a sheath sequentially covering the wire core.

[0006] Furthermore, the non-metallic portion includes a core and a liner, an elastomeric material filling layer, a non-metallic braided layer, and a sheath sequentially covering the core.

[0007] Furthermore, the conductive layer is made of silver-plated soft metal braid.

[0008] Furthermore, the sheath is an F46 sheath.

[0009] Furthermore, the connector assembly includes a nut, a grounding ring, a pressure ring A, a pressure ring B, a metal ring, a housing, and a screw nut. The end of the metal part extends into the nut, and the sheath of the metal part and the nut are sealed with glue. The end of the non-metallic braided layer extends out of the sheath, folds outward, and is located between the nut and the grounding ring. The grounding ring is fitted onto the conductive layer and is fixedly connected to the conductive layer. Pressure ring A is fitted onto the conductive layer and is located next to the grounding ring. The end of the non-metallic braided layer folds outward and is located between pressure ring A and pressure ring B. Pressure ring B is fitted onto pressure ring A. The grounding ring, pressure ring A, and pressure ring B are located inside the nut. The metal ring is fitted onto the wire core, and its side is pressed against the non-metallic braided layer. The housing is fitted onto the metal ring, and the end of the wire core is located inside the housing. The housing is connected to the screw nut.

[0010] Furthermore, the housing and the nut are sealed with glue.

[0011] Furthermore, the front end of the housing, the nut, and the metal portion near the nut are disposed within a protective sleeve.

[0012] Furthermore, the end of the wire core is wound into 8-byte sections and sealed inside the housing with glue.

[0013] Furthermore, there are two grounding rings, and the grounding rings are soldered together with each other and with the conductive layer.

[0014] Working Principle: This invention uses a cable instead of a metal rod as the main body of the oscillator assembly, and the cable has good flexibility. The oscillator assembly requires adjustable metal length; therefore, we divide a cable into two parts, one designed as a metal part and the other as a non-metal part. Adjustable length is achieved by using metal parts of different lengths. The metal component in the metal part is made of silver-plated soft metal braid, which meets the usage requirements of the oscillator assembly.

[0015] Compared with existing technologies, the advantages of this invention are: This invention uses a cable instead of a metal rod, and the cable is a flexible vibrator that can be repeatedly extended and retracted. Tests have shown that this invention can still function normally after multiple 90-degree bends and repeated extensions and retractions, filling a gap in the industry. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Embodiments of the present invention provide an antenna vibrator assembly, such as... Figures 1-2 As shown, it includes cable and connector assemblies.

[0022] The cable is a single cable, divided into a non-metallic section and a metallic section. The metallic section includes a conductor 1 and, sequentially, a liner 2, a conductive layer 3, a non-metallic braided layer 4, and a sheath 5, all wrapped around the conductor 1. The non-metallic section includes a conductor 1 and, sequentially, a liner 2, an elastomer material filling layer 6, a non-metallic braided layer 4, and a sheath 5, all wrapped around the conductor 1. The difference between the metallic and non-metallic sections is that the metallic section uses a metallic conductive layer 3, while the corresponding position in the non-metallic section uses an elastomer material filling layer 6. The conductor 1, liner 2, non-metallic braided layer 4, and sheath 5 in both the metallic and non-metallic sections are integral structures. The conductive layer 3 is made of silver-plated soft metal braid. The sheath 5 is an F46 sheath. The non-metallic braided layer 4 uses reinforcing braided fiber yarn. The conductor 1 uses fiber yarn. The length of the metallic section in the cable is determined according to the antenna's usage requirements.

[0023] The metal part is connected to the connector assembly. The connector assembly includes a nut 7, a grounding ring 8, a retaining ring A9, a retaining ring B10, a metal ring 11, a housing 12, and a nut 13. The end of the metal part extends into the nut 7, and the sheath 5 of the metal part and the nut 7 are sealed with glue. The end of the non-metallic braided layer 4 extends out of the sheath 5, folds outward, and is located between the nut 7 and the grounding ring 8. The grounding ring 8 is fitted onto the conductive layer 3. There are two grounding rings 8, which are soldered together and between the grounding ring 8 and the conductive layer 3. The conductive layer 3 is fitted with a retaining ring A9, which is located next to the grounding ring 8. The end of the non-metallic braided layer 4 folds outward and is located between the retaining ring A9 and the retaining ring B10. The retaining ring B10 is fitted onto the retaining ring A9. The grounding ring 8, retaining ring A9, and retaining ring B10 are located inside the nut 7. The metal ring 11 is fitted onto the wire core 1, and its side is pressed against the non-metallic braided layer 4. The front end of the housing 12 is fitted onto the metal ring 11. The assembly point between the housing 12 and the nut 7, i.e., the gap between the front end of the housing 12, the nut 7, the pressure ring A9, and the metal ring 11, is sealed with epoxy resin. The end of the wire core 1 is wound into 8 strands and sealed inside the housing 12 with epoxy resin. All three epoxy resin filling points are filled with epoxy resin 15. The front end of the housing 12, the nut 7, and the metal portion near the nut 7 are housed within a protective sleeve 14, which is injection molded. The housing 12 is connected to the nut 13. The housing 12 is made of metal.

[0024] This embodiment was able to be used normally after bending and repeated extension / retraction tests, and the signal transmission and reception performance was not affected.

[0025] Bending test, such as Figure 3 As shown, in this embodiment, the cable should be suspended vertically and supported by a connector at one end. A force of 100N F should be applied to the cable in a vertically downward direction. The connector should be bent 90° in one direction along the vertical plane and then returned to its original position, then bent 90° in the opposite direction and returned to its original position, for a total of 4 times, at a bending rate of 20 times / minute.

[0026] Repeated winding and unwinding test: The cable of this embodiment is evenly wound onto a reel with a retraction function and an outer diameter of 80mm ± 5mm. The cable on the reel is arranged in a single layer. The cable at one end of the assembly is fixed to the inner wall of the reel, and the connector at the other end extends no more than 50mm beyond the reel. One winding and unwinding cycle consists of the cable fully extending and retracting. A force F of not less than 1kg is applied to the connector to repeatedly wind and unwind the cable assembly. The winding and unwinding rate is 10 times / minute, and the number of cycles is 30,000. During the tensile test, the cable must remain taut at all times, with a tensile force of at least 1kg. The cable should effectively extend 1.8M, remaining taut throughout; extend to the effective stroke (1.8M) within 10 seconds; and retract (retract) (remain taut) within 10 seconds.
