Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a radio frequency coaxial cable assembly with replaceable interfaces. Background Technology

[0002] In the field of radio frequency (RF) communication, different devices are often equipped with different types of interfaces, which brings many inconveniences to the use of RF coaxial cable assemblies. Traditional RF coaxial cable assemblies have fixed interfaces, and once they are incompatible with the device interface, the entire cable assembly needs to be replaced, resulting in wasted resources. Therefore, designing an RF coaxial cable assembly with replaceable interfaces is of great practical significance. It can improve the versatility of cable assemblies, reduce usage costs, and enhance their adaptability in diverse RF application scenarios.

[0003] As disclosed in the patent announcement CN217848931U, a replaceable interface radio frequency coaxial cable assembly includes a cable mounting structure and a connecting sleeve. The cable mounting structure includes a cable, a sealing pad, a pressing component, an assembly head, a threaded layer, a fastening sleeve, a support component, and a spring. The pressing component is sleeved on the outer side of the cable, and a sealing pad is provided at the connection between the pressing component and the cable. The sealing pad is fixedly connected to the pressing component. A support component is sleeved on the rear end face of the pressing component, and the front end face of the support component is movably connected to the rear end face of the pressing component. Springs are respectively provided at the upper and lower ends of the support component, and the upper and lower end faces of the two springs are fixedly connected to the inner side wall of the pressing component and the outer side wall of the support component, respectively. In this utility model, the cable mounting structure, composed of the cable, sealing pad, pressing component, assembly head, threaded layer, fastener, support component, and springs, solves the problem of the inability to disassemble and replace the interface of the cable assembly.

[0004] However, during use, the sealing gasket of this utility model is prone to aging and deformation after prolonged use, which can lead to cable loosening and difficulty in continued use. The staff would need to replace the entire installation structure, which could result in resource waste and increased maintenance workload. Furthermore, this utility model is only applicable to cables of a single specification, resulting in a narrow range of applications. To address this, we have proposed a radio frequency coaxial cable assembly with replaceable interfaces, which solves the problems of narrow applicability and short service life of this utility model, and improves its practical effect and durability. Utility Model Content

[0005] The purpose of this invention is to provide an RF coaxial cable assembly with a replaceable interface to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A replaceable interface radio frequency coaxial cable assembly includes a cable body, a first mounting mechanism and a second mounting mechanism, the first mounting mechanism and the second mounting mechanism being threadedly connected to each other, and a clamping component being provided inside the first mounting mechanism and the second mounting mechanism.

[0008] Preferably, the clamping assembly includes a movable cavity, an adjusting bolt, a wedge block, a movable hole, and a pressing block. One end of the adjusting bolt is rotatably connected to one end of the wedge block, and the other end of the adjusting bolt passes through the outer wall of the movable cavity and is threadedly connected to the outer wall of the movable cavity. The wedge block is slidably installed inside the movable cavity. The movable cavity has a movable hole at its top. The pressing block is movably installed inside the movable hole and is slidably connected to the movable hole. Limiting ends are fixedly provided at both ends of the pressing block. A rubber pad is fixedly attached to the top of the pressing block. The bottom surface of the pressing block and the top surface of the wedge block have the same inclination angle.

[0009] By adopting the above technical solution: by rotating the adjusting bolt clockwise, the threaded rod drives the wedge block to move along the movable cavity towards the connection end, further driving the extrusion block to move upward along the movable hole until the rubber pad at the top of the extrusion block presses against the cable, thereby achieving the effect of pressing and fixing the cable. This prevents the cable from coming out of the groove due to dragging or other factors during use. At the same time, this fastening method allows cables of different diameters to be installed and fixed inside the cable installation through hole, making the application range more flexible.

[0010] Preferably, the first mounting mechanism includes a first connecting block, a rotating groove, and a connecting sleeve. The rotating groove is formed at one end of the first connecting block, and a rotating block corresponding to the rotating groove is fixedly provided at one end of the connecting sleeve. The rotating block is rotatably connected to the rotating groove. A connecting ring is fixedly provided at the end of the first connecting block away from the rotating groove, and the inner wall of the connecting ring is provided with an internal thread.

[0011] Preferably, the second mounting mechanism includes a second connecting block and a connecting end, the connecting end being fixedly disposed at one end of the second connecting block, the connecting end having an external thread on its outer side, and the first connecting block and the second connecting block having cable mounting through holes inside, the cable mounting through holes communicating with the movable hole.

[0012] By adopting the above technical solution, the first connecting block and the second connecting block can be quickly connected by threading the connecting sleeve of the first installation mechanism with the connecting end of the second installation mechanism. The setting of the rotating groove and the rotating block avoids the cable output torque during the connection installation process.

[0013] Preferably, a strip-shaped handle is fixedly provided at the end of the adjusting bolt away from the wedge block, the second connecting block and the connecting end are integral injection molded structures, and the first connecting block, the second connecting block, and the connecting sleeve are made of polyvinyl chloride, polyethylene, or cross-linked polyethylene materials.

[0014] By adopting the above technical solution—the strip-shaped handle facilitates the rotation of the adjusting bolt by the operator, and the integrated injection-molded structure of the connecting block and the connecting end improves the strength and stability of the component—the advantages of this utility model compared to existing technologies are:

[0015] 1. This replaceable RF coaxial cable assembly utilizes a clamping component within the second mounting mechanism. Clockwise rotation of the adjusting bolt causes the threaded rod to move the wedge block along the movable cavity towards the connection end, further driving the compression block upwards along the movable hole until the rubber pad at the top of the compression block presses against the cable, achieving a clamping and fixing effect. This prevents the cable from slipping out of the groove due to dragging or other factors during use. Furthermore, this fastening method allows for the installation and fixing of cables of different diameters within the cable mounting through-hole, broadening its application range.

[0016] 2. This type of replaceable RF coaxial cable assembly uses a connecting sleeve that is rotatably connected to one end of a first connecting block, and a connecting end provided at one end of a second connecting block. During cable splicing operations, the first and second connecting blocks can be quickly connected and fixed by rotating the connecting sleeve. At the same time, it also facilitates the quick replacement of the interface or the inspection and maintenance of the cable by subsequent personnel.

[0017] 3. This type of replaceable RF coaxial cable assembly, by adjusting the setting of bolts, wedge blocks and compression blocks, can reinforce the cable simply by turning the strip handle when the cable outlet is loose, without having to replace the entire assembly, thereby improving resource utilization.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A replaceable interface radio frequency coaxial cable assembly includes a cable body 1, a first mounting mechanism 2 and a second mounting mechanism 3, the first mounting mechanism 2 and the second mounting mechanism 3 being threadedly connected to each other, and a clamping component 4 being provided inside the first mounting mechanism 2 and the second mounting mechanism 3.

[0026] In this embodiment, preferably, the pressing assembly 4 includes a movable cavity 201, an adjusting bolt 202, a wedge block 203, a movable hole 204, and a pressing block 205. One end of the adjusting bolt 202 is rotatably connected to one end of the wedge block 203, and the other end of the adjusting bolt 202 passes through the outer wall of the movable cavity 201 and is threadedly connected to the outer wall of the movable cavity 201. The wedge block 203 is slidably installed inside the movable cavity 201. The movable hole 204 is opened at the top of the movable cavity 201. The pressing block 205 is movably installed inside the movable hole 204 and is slidably connected to the movable hole 204. Limiting ends 2051 are fixedly provided at both ends of the pressing block 205. A rubber pad 2052 is fixedly attached to the top of the pressing block 205. The bottom surface of the pressing block 205 and the top surface of the wedge block 203 have the same inclination angle.

[0027] The above solution involves rotating the adjusting bolt 202 clockwise, causing the threaded rod to move the wedge block 203 along the movable cavity 201 toward the connecting end 402. This further moves the pressing block 205 upward along the movable hole 204 until the rubber pad 2052 at the top of the pressing block 205 presses against the cable, achieving a pressing and fixing effect on the cable. This prevents the cable from coming out of the groove due to dragging or other factors during use. At the same time, this fastening method allows cables of different diameters to be installed and fixed inside the cable installation through hole 307, making the application range more flexible.

[0028] In this embodiment, preferably, the first mounting mechanism 2 includes a first connecting block 301, a rotating groove 302, and a connecting sleeve 303. The rotating groove 302 is formed at one end of the first connecting block 301. A rotating block 304 corresponding to the rotating groove 302 is fixedly provided at one end of the connecting sleeve 303. The rotating block 304 is rotatably connected to the rotating groove 302. A connecting ring 305 is fixedly provided at the end of the first connecting block 301 away from the rotating groove 302. An internal thread 306 is provided on the inner wall of the connecting ring 305.

[0029] In this embodiment, preferably, the second mounting mechanism 3 includes a second connecting block 401 and a connecting end 402. The connecting end 402 is fixedly disposed at one end of the second connecting block 401. An external thread 403 is provided on the outer side of the connecting end 402. Cable mounting through holes 307 are opened inside the first connecting block 301 and the second connecting block 401. The cable mounting through holes 307 are interconnected with the movable hole 204.

[0030] The above solution achieves a quick docking effect between the first connecting block 301 and the second connecting block 401 by threading the connecting sleeve 303 of the first mounting mechanism 2 and the connecting end 402 of the second mounting mechanism 3 together. The setting of the rotating groove 302 and the rotating block 304 avoids the torque of the cable outlet during the docking installation process.

[0031] In this embodiment, preferably, a strip handle 2021 is fixedly provided at the end of the adjusting bolt 202 away from the wedge block 203, the second connecting block 401 and the connecting end 402 are integral injection molded structures, and the first connecting block 301, the second connecting block 401, and the connecting sleeve 303 are made of polyvinyl chloride, polyethylene, or cross-linked polyethylene materials.

[0032] The above solution, with the addition of the strip handle 2021, facilitates the rotation of the adjusting bolt 202 by the staff. The integral injection molding structure of the connecting block and the connecting end 402 improves the strength and stability of the component.

[0033] In this embodiment, a replaceable RF coaxial cable assembly is used by first inserting the first cable end into the cable mounting through hole 307 inside the second connecting block 401 and adjusting it to a suitable position. Then, by rotating the adjusting bolt 202 clockwise through the clamping component 4 inside the second mounting mechanism 3, the threaded rod drives the wedge block 203 to move along the movable cavity 201 toward the connecting end 402, further driving the pressing block 205 to move upward along the movable hole 204 until the rubber pad 2052 at the top of the pressing block 205 presses against the first cable, achieving a clamping and fixing effect on the first cable. This prevents the cable from coming out of the groove due to dragging or other factors during use. At the same time, this fastening method allows cables of different diameters to be installed and fixed inside the cable mounting through hole 307, making the application range more flexible. Then, the first connecting block 301 with the second cable end installed is connected to the second connecting block 401. The installation and fixing method of the second cable end is the same as that of the first cable end. Finally, the connecting sleeve 303 is installed on the outside of the connecting end 402 and tightened, thus achieving a quick connection between the first connecting block 301 and the second connecting block 401. When it is necessary to replace the connector or to repair and inspect the cable, the adjusting bolt 202 is rotated counterclockwise to move the wedge block 203 toward the adjusting bolt 202, and then the connecting sleeve 303 is rotated in the opposite direction to disengage it from the connecting end 402, thus achieving the disassembly of the component. In actual use, this cable connection method is very convenient for installation and disassembly, facilitating the quick replacement of the interface or the inspection and maintenance of the cable by subsequent staff.
