Description

Bunched cable assembly

Technical Field

The utility model relates to the technical field of radio frequency integrated cable assemblies, in particular to a bunched cable assembly.

Background

In the age of rapid information transmission and communication, the requirements of users on radio frequency flexible cables are more and more severe, and besides the reliability of signal transmission, the users often set various requirements on the use environment and the use conditions of the radio frequency flexible cables. The range of applications for bundled cable assemblies is very broad, from aerospace to marine vessels.

Electronic devices used at present are gradually developed from the initial radio frequency analog circuit to the high frequency digital cable, because the high frequency circuit has better capability in processing data, and the latter is also more widely favored by high-end technology products, especially in the field of military communication. Due to the ever increasing application of high frequency signals, which are inherently very sensitive to the environment, any minor variations will have a more or less effect on the transmission of the high frequency signals, thus causing a change in the overall system performance. Therefore, in the design process of the radio frequency integrated cable assembly, the sealing performance, the compression resistance and the anti-interference capability become more and more focuses of attention of users, and the cable assembly with good sealing performance and strong compression resistance is more excellent in the aspects of signal consistency, stability and integrity and wider in application prospect on the premise that the multi-channel simultaneous transmission is guaranteed.

For example, in the prior art, patent ZL202022653239.2; certain optimization and improvement are carried out on the basis of the disclosed bunched cable assembly. In order to achieve the effect of fully shielding signals during use, the prior patent bunched cable assembly is subjected to full shielding harness treatment outside a conventional cable assembly, namely, as shown in fig. 1, a wave-proof sleeve A woven by inner sleeve wires is sleeved outside a black heat-shrinkable tube B without glue, and the black heat-shrinkable tube A is sleeved outside the wave-proof sleeve A and is provided with certain thickness and elasticity. In the prior art, the wave-proof sleeve is sleeved on the wire and is in a flexible metal net and is in a state of being capable of deforming at will, so that in order to prevent the wire from being bent to be damaged, a slightly hard heat shrinkage tube is sleeved outside the wave-proof sleeve, the diameter of the heat shrinkage tube is only slightly larger than that of the wave-proof sleeve, and after the wave-proof sleeve is sleeved on the wire, the hard heat shrinkage tube is difficult to sleeve, and the installation is inconvenient. Moreover, the mode can achieve an excellent full-shielding effect in the use process, but the whole wire harness and the sleeving process are complex, the strength and the hardness of the cable assembly are insufficient, and damage caused by dragging and treading in the assembly process is easy to cause.

The prior art has the defects that: first, the sealing and shielding effect of the joint is poor. With the connector assembly disclosed in the prior art, although the butt joint between the connector and the cable is achieved, no additional structural member for the butt joint seal is provided for the butt joint of the cable and the connector. Therefore, leakage at the butt joint between the cable and the connector is easy to occur, and the phenomena of sealing performance and anti-interference effect are caused. Second, the compression and tread preventing effects are not significant. With the connector assembly disclosed in the prior art, although damage can be protected for a period of time, long-term aging of the nylon yarn sleeve and loosening of the wave-proof sleeve can be a great potential hazard. Thirdly, the production process is complicated, the sealing technology disclosed in the prior art is adopted, namely, a layer of wave-proof sleeve is wrapped outside the cable assembly, a layer of heat-shrinkable tube is wrapped on the cable to prevent the cable from being cut by the wave-proof sleeve wire harness, and a layer of nylon yarn sleeve is wrapped outside the cable to prevent the wave-proof sleeve from being loose and burr from being cut, so that the production period is prolonged.
