Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency coaxial cables, in particular to a high intermodulation radio frequency coaxial cable assembly. Background Art

[0002] Coaxial cable is a type of electrical wire and signal transmission line, generally made of four layers of material. The innermost layer is a conductive copper wire, surrounded by a layer of plastic, and then a thin mesh conductor is covered by an insulating material. It is often used for signal transmission in various electronic products, especially in the fields of RF signal transmission and antennas.

[0003] However, although most coaxial cables in the existing technology have the function of high intermodulation radio frequency, there are still many problems. Among them, the connection of the coaxial cable port needs to be docked with the connection end, but most coaxial cables currently usually use traditional threaded connection ends for docking. As a result, if the coaxial cable is pulled by the outside world, it will generate a winding force, causing the threaded connection end to rotate slightly. Over time, the threaded connection end will become loose and fall off, affecting the normal operation of the cable.

[0004] Therefore, the present invention provides a high intermodulation radio frequency coaxial cable assembly to solve the above problems. Utility Model Content

[0005] (1) Technical problems solved

[0006] The utility model provides a high intermodulation radio frequency coaxial cable assembly, which aims to solve the problem mentioned in the background technology that the connection of the existing coaxial cable ports is usually connected by using a threaded connection end. As a result, if the coaxial cable is pulled by the outside world, the threaded connection end will become loose due to the winding force when the cable is pulled, causing the cable port to be disconnected and the cable operation to be interrupted.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high intermodulation radio frequency coaxial cable assembly, comprising a coaxial cable body, connector ends are provided at both ends of the coaxial cable body, an intermediate connector is provided inside the connector end, a first bevel card block and a limiting block are fixedly connected to the outer surface of the intermediate connector, a second bevel card block that is clamped with the first bevel card block is fixedly connected to the outer surface of the connector end, the second bevel card block is obliquely adapted to one side of the first bevel card block, and a limiting groove is provided on the outer wall of the second bevel card block for the limiting block to be embedded.

[0009] As a preferred technical solution of the present application, a protective cover is provided on the outer surface of the coaxial cable body, and the connector end is located inside the protective cover.

[0010] As a preferred technical solution of the present application, a first limiting block and a second limiting block are fixedly connected to the outer surface of the protective cover, and a slot for inserting the second limiting block is provided inside the first limiting block.

[0011] As a preferred technical solution of the present application, the first limit block is internally slidably connected to a limit rod, and the second limit block is internally provided with a limit hole for the limit rod to be inserted.

[0012] As a preferred technical solution of the present application, the limiting rod is inserted into the slot, and the top of the first limiting block is fixedly connected with a spring.

[0013] As a preferred technical solution of the present application, one end of the spring away from the first limiting block is fixedly connected to the limiting rod, and the limiting rod is inserted into the inner ring of the spring.

[0014] (3) Beneficial effects

[0015] The utility model is provided with the connector end head, the intermediate connector, the first bevel card block, the second bevel card block, the limiting block and the limiting groove. When the two connector end heads are moved closer to the intermediate connector, the two connector end heads respectively drive the second bevel card block to contact the first bevel card block on the intermediate connector. When the first bevel card block and the second bevel card block are inclined and adapted, the second bevel card block can be squeezed by the inclined surface of the first bevel card block to achieve a slight downward movement, so that the second bevel card block can smoothly move to a suitable position to form a clamping state with the first bevel card block. The limiting blocks on the intermediate connector can be correspondingly snapped into the limiting grooves to ensure that the two connector ends will not rotate, thereby achieving the purpose of docking the ports of the coaxial cable body, and the docking is convenient, stable and firm. Furthermore, this device allows the coaxial cable body to abandon the traditional use of threaded connection ends for docking, thereby ensuring that if the coaxial cable body is pulled by the outside world, even if the coaxial cable body generates a tangling force, it is difficult to cause the connector ends and the intermediate connector to loosen, thereby improving the stability of the coaxial cable body.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a high intermodulation radio frequency coaxial cable assembly, such as Figure 1-5 As shown, the cable assembly includes a coaxial cable body 1, connector ends 2 are provided at both ends of the coaxial cable body 1, an intermediate connector 3 is provided inside the connector end 2, the outer surface of the intermediate connector 3 is fixedly connected to a first bevel card block 4 and a limiting block 5, the outer surface of the connector end 2 is fixedly connected to a second bevel card block 6 that is clamped with the first bevel card block 4, the second bevel card block 6 is obliquely adapted to one side of the first bevel card block 4, and the outer wall of the second bevel card block 6 is provided with a limiting groove 7 for the limiting block 5 to be embedded.

[0025] When the two connector ends 2 respectively drive the second bevel card block 6 toward the middle connector 3, the second bevel card block 6 can come into contact with the first bevel card block 4, so that the second bevel card block 6 utilizes the oblique fit with the first bevel card block 4 so that when the second bevel card block 6 is squeezed by the first bevel card block 4, the second upper card block can smoothly move to the inner side of the first bevel card block 4 to achieve the card connection between each other, so as to achieve the purpose of docking between the two connector ends 2 and the middle connector 3, and using this installation method can ensure that when the coaxial cable body 1 is pulled by the outside, the winding force generated by itself cannot be shaken The docking stability between the two connector ends 2 and the intermediate connector 3 prevents the traditional threaded connection end from being rotated and loosened over time when subjected to winding force, and when the first bevel block 4 and the second bevel block 6 are connected, the limiting block 5 can be snapped into the corresponding limiting groove 7, so that when the limiting block 5 is snapped into the limiting groove 7, it can be ensured that the two connector ends 2 and the intermediate connector 3 cannot rotate, so that a long-term installation and fixing effect can be formed between the first bevel block 4 and the second bevel block 6, preventing the two connector ends 2 and the intermediate connector 3 from falling off.

[0026] A protective cover 8 is provided on the outer surface of the coaxial cable body 1 , and the connector end 2 is located inside the protective cover 8 .

[0027] The protective cover 8 provides the two connector ends 2 and the intermediate connector 3 with an effective protective space, thereby ensuring that the two connector ends 2 and the intermediate connector 3 are unlikely to be damaged when stepped on by the outside, thereby improving the damage resistance of the two connector ends 2 and the intermediate connector 3, ensuring the normal use of the two connector ends 2 and the intermediate connector 3, and reducing the probability of property loss caused by damage to the two connector ends 2 and the intermediate connector 3. In addition, the protective cover 8 utilizes the sliding fit with the coaxial cable body 1 to provide corresponding protection according to needs. Therefore, when the two connector ends 2 and the intermediate connector 3 need to be disassembled, the protective cover 8 can slide to any position so that the staff can smoothly disassemble the two connector ends 2 and the intermediate connector 3.

[0028] The outer surface of the protective cover 8 is fixedly connected with a first limiting block and a second limiting block. The interior of the first limiting block is provided with a slot 10 for inserting the second limiting block.

[0029] When the second limit block is inserted into the slot 10 in the first limit block, the two protective covers 8 can be merged to prevent the formation of gaps between the protective covers 8 and the entry of dust, thereby avoiding dust affecting the use of the two connector ends 2 and the intermediate connector 3. In addition, the second limit block is inserted into the slot 10 in the first limit block to facilitate subsequent fixation between the two.

[0030] The first limiting block is internally connected to the limiting rod 11 in a sliding manner, and the second limiting block is internally provided with a limiting hole 13 for the limiting rod 11 to be inserted into.

[0031] When the second limit block is inserted into the slot 10 in the first limit block, the limit rod 11 can be used to insert into the corresponding limit hole 13, so that when the limit rod 11 is inserted into the limit hole 13, the installation between the two protective covers 8 can be achieved, preventing the two protective covers 8 from separating, thereby ensuring the installation firmness between the two protective covers 8 and ensuring that the two connector ends 2 and the intermediate connector 3 can be protected for a long time.

[0032] The limiting rod 11 is inserted into the slot 10 , and a spring 12 is fixedly connected to the top of the first limiting block. The end of the spring 12 away from the first limiting block is fixedly connected to the limiting rod 11 , and the limiting rod 11 is inserted into the inner circle of the spring 12 .

[0033] The spring 12 gives the limit rod 11 an elastic adjustment force. When the second limit block is located in the slot 10, the limit hole 13 on the second limit block can achieve position correspondence with the limit rod 11. Therefore, when the limit rod 11 is in the vacuum position of the limit hole 13, the limit rod 11 can use the elastic force provided by the spring 12 to fit into the limit hole 13 to achieve installation between the first limit block and the second limit block, so as to ensure the combined stability between the two protective covers 8.

[0034] Working principle:

[0035] When it is necessary to dock the connector ends 2 and the intermediate connector 3 at both ends of the coaxial cable body 1, first pick up the two connector ends 2 and move them closer to the intermediate connector 3, so that the two connector ends 2 respectively drive the second bevel clamping block 6 to contact the first bevel clamping block 4 on the intermediate connector 3, so that the second bevel clamping block 6 can use the bevel between the first bevel clamping block 4 to cooperate with the bevel between the second bevel clamping block 6 and the first bevel clamping block 4. When the bevel is squeezed by the bevel of the first bevel clamping block 4, the second bevel clamping block 6 can be smoothly moved to the appropriate position to form a card connection with the first bevel clamping block 4, so as to achieve the purpose of docking between the two connector ends 2 and the intermediate connector 3. At the same time, the limiting block 5 can be stuck in the corresponding limiting groove 7, thereby further ensuring the docking stability between the two connector ends 2 and the intermediate connector 3.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
