Flexible strip-shaped cable and radio frequency assembly

Abstract

The invention discloses a flexible strip-shaped cable and a radio frequency assembly. The flexible strip-shaped cable is provided with a strip-shaped cable insulator, wherein a cable inner conductor is buried in the cable insulator, the cable inner conductor is a strip-shaped component, the cable inner conductor is buried in the cable insulator along the length direction, a width surface of the cable insulator is provided with a cable outer conductor in an attached manner, and the cable outer conductor is wrapped by a cable protection sleeve. The cable is advantaged in that the cable is resistant to clamping, small in thickness and stable in signal transmission, and a damage failure phenomenon occurring in the process from outdoor to indoor is effectively avoided. The radio frequency assembly comprises the flexible strip-shaped cable and radio frequency connectors installed at two ends of the cable, and problems that pinching, damage and the like occur when radio frequency signals aretransmitted back to the indoor space from the outdoor space and pass through a window or a door frame are solved.

Description

technical field [0001] The invention relates to a signal transmission device and belongs to the field of connectors, in particular to a flexible ribbon cable and a radio frequency assembly. Background technique [0002] At present, there are two methods to solve the transmission of radio frequency signals from outdoor to indoor. One is to directly punch holes in the building wall, and then pass the radio frequency cable through the wall hole, and realize indoor and outdoor signal transmission through the penetrated cable assembly; One is to use a bendable semi-flexible cable assembly with a certain flat shape to realize signal transmission through building windows; both have different advantages and disadvantages. The first one has the advantage of low requirements for radio frequency cable assemblies. In terms of service life, it is stable and reliable; the disadvantage is that it is necessary to drill holes in the building, which will damage the building and it is troubles...

Problems solved by technology

[0002] At present, there are two methods to solve the transmission of radio frequency signals from outdoor to indoor. One is to directly punch holes in the building wall, and then pass the radio frequency cable through the wall hole, and realize indoor and outdoor signal transmission through the penetrated cable assembly; One is to use a bendable semi-flexible cable assembly with a certain flat shape to realize signal transmission through building windows; both have different advantages and disadvantages. The first one has the advantage of low requirements for radio frequency cable assemblies. In terms of service life, it is stable and reliable; the disadvantage is that it is necessary to drill holes in the building, which will damage the building and it is troublesome to seal the holes because of the rain; Hole situation; Disadvantage Although the use of double rails ensures the compressive performance of the RF cable assembly and improves the life of the assembly, but due to the addition of double rails, the entire assembly is relatively hard (with a certain degree of bending flexibility), and the thickness of the cable assembly is relatively thick , when passing through the window, the window may not be closed tightly during the process of closing the window, and there may be gaps (mainly European-style windows through cables);

[0003] There are two main disadvantages in the existing semi-flexible cable assembly with double track protection. One is that the bending flexibility is poor and it has a certain hardness; In windy and rainy weather, rainwater may flow from the outdoors into the indoors through the gaps
