Description

Technical Field

[0001] This utility model belongs to the field of coaxial cable technology, specifically a highly flexible coaxial cable. Background Technology

[0002] Coaxial cable harnesses are a type of wire and cable used to transmit high-frequency signals. Their core feature is that they are made up of a central conductor, an insulation layer, a shielding layer, and an outer sheath, which are wrapped from the inside out. This effectively resists external electromagnetic interference and ensures stable signal transmission. Most existing wire harness interfaces use snap-fit ​​and plug-in methods for connection, which makes the wire harness connector connection less compact and stable, and it is easy for the connection to be loose and short-circuited.

[0003] Meanwhile, a layered coaxial cable bundle with announcement number CN 215645286 U is disclosed; it includes a first joint and a second joint. The first joint has a positioning block welded to one side of the top and bottom outer walls, and the second joint has a sleeve connected to one side of the top and bottom outer walls via a rotating shaft. The sleeve is sleeved on the outside of the positioning block, and a lead screw is threaded to the center of the positioning block. One end of the lead screw is welded to a rotating wheel, and the other end of the lead screw away from the rotating wheel is connected to a top holding plate via a bearing. The top holding plate is in contact with one side of the inner wall of the sleeve.

[0004] The aforementioned layered coaxial cable harness lacks an effective fixing structure at the connection between the coaxial cable harness body and the connector during use. The stress generated by bending and pulling during use can easily cause damage to the connection, leading to failure and significantly shortening the overall service life of the coaxial cable harness. At the same time, the connection structure of the connector is inconvenient to disassemble and assemble, affecting the efficiency of disassembly and assembly.

[0005] Therefore, a highly flexible coaxial cable is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a highly flexible coaxial cable harness. It features precise locking of the connector head through the cooperation of the connecting rod and the limiting component, convenient assembly and disassembly, and the use of the wire pressing component to press the cable harness to reduce stress damage at the connection point. This significantly improves operating efficiency, reduces maintenance costs, and extends the service life of the coaxial cable harness.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a highly flexible coaxial cable harness, comprising a coaxial cable harness body and a first connector and a second connector connected to each other. A connecting rod and a limiting assembly are respectively provided at opposite ends of the first connector and the second connector. The limiting assembly includes a limiting frame, a pressing block, a toothed plate, a return spring, and a rotating block. A wire pressing assembly is connected to opposite ends of the first connector and the second connector. The wire pressing assembly includes a connecting frame, a rotating screw, and a wire pressing plate. The coaxial cable harness body is disposed inside the wire pressing assembly, and one end of the coaxial cable harness body is respectively connected and fixed to the first connector and the second connector.

[0008] Preferably, the coaxial cable bundle body includes a central conductor, an insulating layer, a shielding layer, a braided layer, and an outer sheath, wherein the insulating layer, shielding layer, braided layer, and outer sheath are arranged sequentially from the inside to the outside of the central conductor.

[0009] Preferably, the first connector is convex and the second connector is concave.

[0010] Preferably, the connecting rods are symmetrically arranged on both sides of the first connector, and the limiting components are symmetrically arranged on one side of the second connector, corresponding to the positions of the connecting rods.

[0011] Preferably, the limiting frame is fixed on the side wall of the second connector, the pressing blocks are symmetrically arranged at both ends of the limiting frame, the toothed plate is fixed at the bottom end of the pressing block, the return spring is arranged inside the limiting frame, and the two ends of the return spring abut against the pressing blocks at both ends respectively.

[0012] Preferably, the rotating block is arranged in a ring shape, and the rotating block is rotatably connected to the limiting frame through a shaft. The rotating block is provided with half teeth and limiting protrusions respectively.

[0013] Preferably, the half-tooth on the rotating block meshes with the tooth groove on the tooth plate, and the connecting rod is provided with a groove that matches the limiting protrusion.

[0014] Preferably, the rotating screw is threadedly connected to the center position of the connecting frame, one end of the rotating screw is connected to the pressure plate through a movable locking block, both ends of the pressure plate are slidably connected to the inner wall of the connecting frame, and the pressure plate is evenly provided with clamping grooves that match the shape of the coaxial cable bundle body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 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.

[0028] The following describes an embodiment of this utility model based on its overall structure.

[0029] like Figures 1 to 5 As shown, this utility model provides a highly flexible coaxial cable harness, including a coaxial cable harness body 1 and a first connector 2 and a second connector 3 connected to each other. A connecting rod 4 and a limiting component 5 are respectively provided at opposite ends of the first connector 2 and the second connector 3. The mating end of the first connector 2 is inserted into the mating end of the second connector 3. Simultaneously, the connecting rod 4 and the limiting component 5 adopt a plug-in / pull-out mating structure to lock the connector. The limiting component 5 includes a limiting frame 51, a pressing block 52, a toothed plate 53, a return spring 54, and a rotating block. 55. The opposite ends of the first connector 2 and the second connector 3 are connected to a wire clamping assembly 6. The wire clamping assembly 6 includes a connecting frame 61, a rotating screw 62 and a wire clamping plate 63. The coaxial cable harness body 1 is disposed inside the wire clamping assembly 6. The wire clamping assembly 6 clamps and fixes the coaxial cable harness body 1, which can reduce stress damage at the cable harness connection. One end of the coaxial cable harness body 1 is connected and fixed to the first connector 2 and the second connector 3 respectively. The coaxial cable harness body 1 is fixed to the conductive terminal inside the connector by welding to ensure signal conduction.

[0030] In this embodiment, the coaxial cable harness body 1 includes a central conductor 11, an insulating layer 12, a shielding layer 13, a braided layer 14, and an outer sheath 15. The insulating layer 12, the shielding layer 13, the braided layer 14, and the outer sheath 15 are arranged sequentially from the inside to the outside of the central conductor 11. The layers tightly cover each other from the inside to the outside, without gaps, reducing interlayer friction during bending, avoiding delamination and cracking, and significantly improving the flexibility of the cable harness body.

[0031] The first connector 2 is convex, and the second connector 3 is concave. The convex and concave shapes are matched to achieve pre-positioning of the connectors, avoiding misalignment or displacement during docking and improving insertion and removal efficiency.

[0032] The connecting rods 4 are symmetrically arranged on both sides of the first connector 2, and the limiting components 5 are symmetrically arranged on one side of the second connector 3, corresponding to the position of the connecting rods 4, to ensure that the connecting rods 4 and the limiting components 5 are precisely matched, to avoid locking failure due to misalignment, and to improve connection reliability.

[0033] The limiting frame 51 is fixed on the side wall of the second connector 3. The pressing blocks 52 are symmetrically arranged at both ends of the limiting frame 51. The toothed plate 53 is fixed at the bottom end of the pressing block 52. The return spring 54 is arranged inside the limiting frame 51, and the two ends of the return spring 54 abut against the pressing blocks 52 at both ends respectively. The elastic force of the return spring 54 can automatically drive the pressing block 52 to reset without manual reset, simplifying the operation. At the same time, the return spring 54 acts evenly on the upper and lower pressing blocks 52 to ensure the synchronous transmission of the toothed plates 53 on both sides.

[0034] The rotating block 55 is arranged in a ring shape and is rotatably connected to the limiting frame 51 through a shaft. The rotating block 55 is provided with a half tooth 56 and a limiting protrusion 57 respectively. The limiting protrusion 57 has a self-locking effect after it is locked into the groove of the connecting rod 4, preventing accidental unlocking caused by vibration.

[0035] The half tooth 56 on the rotating block 55 meshes with the tooth groove on the tooth plate 53. The connecting rod 4 is provided with a groove that matches the limiting protrusion 57. The shape of the limiting protrusion 57 and the groove are complementary. With the help of the guide slope, the locking process is smooth and without jamming. The groove can adapt to the slight radial shaking of the connecting rod 4, ensuring that the limiting protrusion 57 is always locked and improving the vibration resistance of the connection.

[0036] The rotating screw 62 is threadedly connected to the center of the connecting frame 61. One end of the rotating screw 62 is connected to the pressure plate 63 through a movable locking block. Both ends of the pressure plate 63 are slidably connected to the inner wall of the connecting frame 61. The pressure plate 63 has evenly spaced grooves that match the shape of the coaxial cable harness body 1. By rotating the screw 62, the pressure plate 63 is moved downward, which, together with the connecting frame 61, can press and fix the coaxial cable harness body 1, reducing stress damage at the cable harness connection and preventing loosening of the connection between the cable harness and the connector due to pulling or bending.

[0037] The working principle and process of a highly flexible coaxial cable bundle: The coaxial cable bundle body 1 consists of a central conductor 11, an insulating layer 12, a shielding layer 13, a braided layer 14, and an outer sheath 15, arranged from the inside out. The hierarchical structure works together to achieve signal transmission and high flexibility. The first connector 2 is convex and the second connector 3 is concave. Initial positioning is achieved through the convex-concave fit. At the same time, the connecting rods 4 on both sides of the first connector 2 are inserted into the limiting components 5 at the corresponding positions of the second connector 3, pressing the pressing blocks 52 at both ends of the limiting frame 51, causing the toothed plate 53 to move downward. The toothed plate 53 engages with the half teeth 56 on the rotating block 55 through the tooth groove, driving the rotating block 55 to rotate around the shaft, causing the limiting protrusion 57 on the rotating block 55 to rotate. After the connecting rods 4 are fully inserted into the limiting frame 51... Release the pressing block 52, and the reset spring 54 pushes the pressing block 52 to reset, which in turn drives the toothed plate 53 and the rotating block 55 to reset, so that the limiting protrusion 57 is inserted into the groove of the connecting rod 4, thus completing the locking and fixing of the connector. When disassembling, only the pressing block 52 needs to be pressed, which is convenient for the disassembly and assembly of the connector. The two ends of the coaxial cable harness body 1 pass through the connecting frame 61 of the wire pressing assembly 6. Rotate the rotating screw 62 in the center of the connecting frame 61, and drive the wire pressing plate 63 to slide along the inner wall of the connecting frame 61 through the thread transmission. The clamping groove on the wire pressing plate 63 matches the shape of the coaxial cable harness body 1. The pressure of the wire pressing plate 63 tightly fixes the coaxial cable harness body 1 in the connecting frame 61, preventing the connection between the cable harness and the connector from loosening due to pulling or bending, and ensuring the stability of signal transmission.
