Description

Cable forming device

Technical Field

The invention relates to the technical field of cable processing equipment, in particular to a cable forming device.

Background

At present, with the rapid increase of the operating frequency of electronic equipment, hundreds of MHz and even more than dozens of GHz are usually reached. In its most basic form, a semi-rigid cable assembly is a coaxial transmission line formed from a metal tube. The metal tube is a copper tube forming an outer conductor, and a metal wire conductor is arranged along the center line of the copper tube. The central wire conductor is supported by the dielectric material so as to be maintained on the same central axis as the outer conductor. The following list is the most important understanding of the 5 points for semi-rigid cables:

1) independent microwave assembly: it is first of all clear that the semi-rigid cable assembly itself is a critical class of microwave assemblies, which means that the specifications of the semi-rigid cable are of the same importance as the specifications of any coupler, bridge, or even amplifier. If properly made, the cable can successfully provide a predictable stabilizing effect in connecting other components of the system. As long as any good link budget analysis is studied, it can be found that at a given frequency, electrical parameters including attenuation and voltage standing wave ratio play a crucial role in transmission and reception of radio frequency signals.

2) Wide band coverage: semi-rigid cable assemblies can typically support radio frequency signal transmission within 65 GHz. Furthermore, although not commonly used, cable assemblies using 1.0mm connector terminations can achieve high frequency applications up to 110 GHz. Semi-rigid coaxial cables vary in size and range in diameter from 0.020 inches to 0.250 inches. The 0.141 inch diameter semi-rigid coaxial cable is terminated with high frequency SMA or 2.92mm connectors, typically up to 27 GHz. A 0.086 inch diameter semi-rigid coaxial cable, although also commonly used with SMA connectors, has an operating frequency of up to 65GHz when terminated by a 1.85mm connector.

3) Shaping and shape retention: such cable assemblies often need to be precisely molded into various shapes in order to fit within the designed system. As the name implies, a semi-rigid coaxial cable is a cable that is both rigid enough to maintain its shape and flexible enough to be manually bent. It is a risky task to mold the semi-rigid cable into the desired shape. To prevent damage to the outer tube wall, special tools should be used to bend or shape the cable. In addition, once such cables are shaped into a particular shape, it is extremely difficult to change their shape again. This is because the shape change often results in damage to the outer conductor, thereby creating fine lines in the outer wall, ultimately affecting the electrical performance of the cable assembly. Thus, although such coaxial cables made of aluminum and soft copper are easy to shape and bend by hand, in order to minimize the risk of cable damage, it is still recommended to use special tools for such operations.

4) Phase stability: since the semi-rigid coaxial cable is made of a high quality material, it has an extremely high electrical stability as compared with a flexible coaxial cable using a braided layer outer conductor. The properties of metal and dielectric materials change with temperature, and thus the use of phase-stable cables is of great importance for many critical systems. Furthermore, in systems where phase length control is required, phase matched semi-rigid cables are often used. This is particularly true for antenna systems configured with phased array antennas. This is because, in such an antenna system, the phase of the input signal has an important role in electrically controlling the main beam of the antenna array. Modern mobile communication systems use this technique to optimize the coverage under varying conditions in order to reduce the number of antennas required for system performance optimization.

5) Low Passive Intermodulation (PIM): semi-rigid cable assemblies are typically made of non-ferrous metal materials (primarily copper). Such copper-tube semi-rigid coaxial cables have extremely good passive intermodulation performance when properly mated, making them ideal for modern multi-frequency wireless communication systems, including Distributed Antenna System (DAS) related equipment. As the demand for full coverage increases, distributed antenna systems require the use of a greater variety of low passive intermodulation products, including power dividers, combiners, amplifiers, and even high-end test equipment. Semi-rigid cable assemblies are the best configuration for distributed antenna applications because they can simultaneously meet the radio frequency power and passive intermodulation requirements required by modern wireless communication systems.

In summary, semi-rigid cable assemblies are a vital microwave device, active in countless radio frequency applications worldwide today. While semi-rigid technology is not new, semi-rigid assemblies remain the popular choice for engineers due to their broadband characteristics, reliable electrical performance, and phase stability.

A locking hoop 150 is arranged between the two guide rails, and the bottom surface of the locking hoop 150 is propped against the top surface of the blocking frame. Specifically, the main frame is connected with the bracket through a hexagonal slotted bolt; the pressing plate is used for pressing the hexagon slotted bolt, so that the main frame cannot shift due to reaction force in the molding operation process, and the stability of the mechanism during molding is improved.

Other examples are as follows:

the shape of the shell is square or other irregular shapes, and can be adjusted according to actual needs. One end of the adjusting screw, which extends out of the limiting hole, can be provided with a locking nut, and the locking nut can play a better locking and fixing role. The number of the limiting mechanisms is two, and the limiting mechanisms are symmetrically distributed on the two long side walls of the base. The supporting cylinder can be of a solid structure or a hollow structure, and the supporting cylinder can be integrally formed with the supporting shaft or in clearance fit with the supporting shaft. While only certain features and embodiments of the application have been illustrated and described, many modifications and changes may occur to those skilled in the art (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the scope and spirit of the invention in the claims.

Finally, it should be noted that: the above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention should not be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
