Description

Technical Field

[0001] The utility model relates to the technical field of cable assemblies, in particular to a semi-rigid cable assembly. Background Art

[0002] Semi-rigid cable is a cable design that combines flexibility and rigidity. It usually consists of multiple insulated wires or optical fibers wrapped in a soft but rigid protective shell. This component usually consists of a series of metal wires or optical fibers wrapped in a soft but rigid protective shell. The semi-rigidity of this component gives it better controllability and stability, while also having a certain degree of flexibility and can adapt to a certain degree of bending or shape changes. This enables it to reliably transmit power or signals in complex engineering environments, improving the performance and reliability of the system.

[0003] The size of the connector on the traditional semi-rigid cable assembly after bending is the assembly size. When tightening the nut on the female head, the size of the thread overlap needs to be bent and adjusted, that is, the angle of the already bent assembly needs to be reduced before it can be assembled. In this way, the semi-rigid assembly will repeatedly adjust the bending size during disassembly or installation, and the cable will be damaged. In addition, the B3 cable has a diameter of 3.6mm, and the size is not easy to adjust during assembly, which will also affect the service life of the female connector on the transverse box end module and the installation efficiency of the semi-rigid cable.

[0004] And because there is an insulating support between the inner and outer conductors, it is inevitable to introduce a step structure at the insulating support. The characteristic impedance at the step will change to a certain extent, introducing discontinuous capacitance. In order to achieve a small residual reflection in an extremely wide frequency band, the remaining discontinuous capacitance must be compensated in the same plane. At this time, another step is needed for impedance compensation, and a barb structure is provided on the outer conductor for the fixation of the insulator. Both of these situations will affect the electrical performance of the product. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a semi-rigid cable assembly, which aims to improve the problem that the size of traditional semi-rigid cable assemblies is difficult to adjust during assembly, which will also affect the service life of the female connector on the cross box end module and the installation efficiency of the semi-rigid cable.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a semi-rigid cable assembly, comprising an outer conductor, a connecting nut is arranged on the outer wall of the outer conductor, an outer conductor is arranged inside the connecting nut, a retaining spring is arranged inside the connecting nut, a center conductor is fixedly connected inside the connecting nut, an insulator is arranged on the side wall of the center conductor, a sealing ring is sleeved on the outer wall of the insulator, the outer conductor is slidably connected to the outer wall of the insulator, and a connecting assembly is arranged on the side wall of the connecting nut.

[0007] Furthermore, the connection assembly includes a cable, one end of the cable is arranged inside the connection nut.

[0008] Furthermore, a rotating plate is fixedly connected to the outer wall of the cable, and a plurality of connecting blocks are rotatably connected to the side wall of the rotating plate.

[0009] Furthermore, each of the side walls of the connection blocks is rotatably connected to a connection piece, and the side wall of the connection piece at the top is fixedly connected to a fixing ring 1.

[0010] Furthermore, a rotating column 1 is fixedly connected to one side wall of the fixing ring, and a plurality of connecting shafts are rotatably connected inside the rotating column 1.

[0011] Furthermore, a second fixing ring is fixedly connected to a side wall of the connecting member at the bottom, and a second rotating column is fixedly connected to a side wall of the second fixing ring.

[0012] Furthermore, the two side walls of the rotating column are rotatably connected to the bottom of the connecting shaft.

[0013] Furthermore, one end of the connecting shaft is fixedly connected to a turning handle, and a side wall of the turning handle is rotatably connected to the inside of the second turning column.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, firstly, the nut is moved back, thus saving a part of the thread size that overlaps with the female connector. The saved assembly size facilitates chassis assembly, reduces repeated adjustments of the size at the bending part of the semi-rigid cable assembly, and avoids affecting the service life of the female connector on the horizontal box end module and the installation efficiency of the semi-rigid cable.

[0016] 2. In the utility model, the tilt angle is changed by pulling the turning handle, so that the connecting shaft drives the fixing rings 1 and 2 at both ends to change the variable tilt angle of the connecting piece on the side wall of the turning plate, thereby the cable can be fixed for a second time to prevent excessive displacement when bending, providing protection for the installation of semi-steel cables.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a semi-rigid cable assembly, including an outer conductor 1, a connecting nut 6 is arranged on the outer wall of the outer conductor 1, the outer conductor 1 is arranged inside the connecting nut 6, a retaining spring 5 is arranged inside the connecting nut 6, a center conductor 2 is fixedly connected inside the connecting nut 6, an insulator 3 is arranged on the side wall of the center conductor 2, a sealing ring 4 is sleeved on the outer wall of the insulator 3, the outer conductor 1 is slidably connected to the outer wall of the insulator 3, and a connecting assembly is arranged on the side wall of the connecting nut 6.

[0024] Specifically, the outer conductor 1 is located between the surface of the center conductor 2 and the insulator 3, and plays the role of balancing the electric field, reducing the voltage gradient in the cable, and ensuring uniform distribution of the electric field, which helps to reduce the risk of dielectric breakdown in the cable and improve the performance and stability of the cable. Pulling the connecting nut 6 can save a part of the thread size when connecting with the female head. Through the retaining spring 5, the connecting nut 6 can be quickly reset after retreating, reducing the repeated adjustment of the size of the bending part of the semi-rigid cable assembly, avoiding affecting the service life of the female connector on the horizontal box end module and the installation efficiency of the semi-rigid cable. This structural design optimizes the assembly process and improves the assembly efficiency and system reliability.

[0025] Reference Figure 3The connecting component includes a cable 8, one end of which is arranged inside the connecting nut 6, a rotating plate 14 is fixedly connected to the outer wall of the cable 8, a plurality of connecting blocks 9 are rotatably connected to the side wall of the rotating plate 14, a connecting piece 10 is rotatably connected to the side wall of each connecting block 9, a fixing ring 11 is fixedly connected to the side wall of the top connecting piece 10, a rotating column 12 is fixedly connected to the side wall of the fixing ring 11, a plurality of connecting shafts 13 are rotatably connected inside the rotating column 12, a fixing ring 2 15 is fixedly connected to the side wall of the bottom connecting piece 10, a rotating column 2 16 is fixedly connected to the side wall of the fixing ring 2 15, a rotating column 2 16 is rotatably connected to the bottom of the connecting shaft 13, a turning handle 7 is fixedly connected to one end of the connecting shaft 13, and a side wall of the turning handle 7 is rotatably connected inside the rotating column 2 16.

[0026] Specifically, the operator can turn the handle 7, and the handle 7 changes the inclination angle while rotating inside the turn column 16, pulling the connecting shaft 13 to rotate inside the turn column 12, and causing the inclination angle of the connecting shaft 13 to change accordingly. The movement of the connecting shaft 13 simultaneously pushes the fixing ring 11, and the fixing ring 11 drives the connecting member 10 to rotate on the side wall of the connecting block 9 after being subjected to the force. At the same time, the connecting block 9 also starts to rotate on the side wall of the rotating plate 14. At this time, the fixing ring 2 15 at the bottom will also rotate synchronously on the side wall of the rotating plate 14. This process realizes the secondary fixation of the semi-steel cable by changing the position of the connecting shaft 13. When the cable 8 is bent, this secondary fixation can prevent it from excessive displacement, providing additional protection for the installation of the semi-steel cable.

[0027] Working principle: When installing the semi-steel cable, first pull the connection nut 6 to make it retreat backwards, the connection nut 6 is protected from the external environment and mechanical damage, and its pulling can save the connection distance when connecting with the female head, and the outer conductor 1 is located between the surface of the center conductor 2 and the insulator 3. Its function is to balance the electric field, reduce the voltage gradient in the cable, and ensure uniform distribution of the electric field. This helps to reduce the risk of dielectric breakdown in the cable and improve the performance and stability of the cable. The retaining spring 5 can make the connecting nut 6 quickly reset after retreating, so that the structure saves a part of the thread size that overlaps with the female connector. The saved assembly size facilitates chassis assembly, reduces the repeated adjustment of the size of the bending part of the semi-rigid cable assembly, and avoids affecting the service life of the female connector on the horizontal box end module and the installation efficiency of the semi-rigid cable. When it is necessary to fix the handle 7 for a second time, turn the handle 7, and the handle 7 changes the inclination angle while rotating inside the rotating column 16, pulling the connecting shaft 13 to rotate inside the rotating column 12 and changing the inclination angle of the connecting shaft 13. The connecting shaft 13 moves while pushing the fixing ring 11. After the fixing ring 11 is subjected to force, it drives the connecting member 10 to rotate on the side wall of the connecting block 9, and the connecting block 9 rotates on the side wall of the rotating plate 14. At this time, the fixing ring 2 15 at the bottom also rotates synchronously on the side wall of the rotating plate 14. In this process, the cable 8 can be fixed for a second time to prevent it from excessive displacement when bending, which provides a guarantee for the installation of semi-rigid cables.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
