Description
Technical Field
The utility model relates to a cable manufacturing technical field especially relates to a radio frequency cable of resistant bending.
Background
Radio frequency cables are cables for transmitting electromagnetic energy in a radio frequency range, are indispensable elements in various radio communication systems and electronic equipment, and are applied to the field of radio frequency communication testing, particularly in small space testing, chip testing, cluster testing and dynamic bending environments. The existing radio frequency cable generally has the structure of a silver-plated copper conductor, a low-density polytetrafluoroethylene dielectric, a silver-plated copper strip wrapped shielding layer, a silver-plated copper wire braided shielding layer and an outer sheath. The radio frequency cable with the structure has poor bending life and is easy to damage when used as a dynamic bending or testing cable, and the conventional solution is to add a layer of armor on the radio frequency cable to prolong the service life of the radio frequency cable. However, the weight and the outer diameter of the radio frequency cable after being additionally provided with the armor are increased greatly, so that the use of customers is seriously influenced, and even the radio frequency cable cannot be used, and therefore, a radio frequency cable capable of solving the problems is urgently needed in the market.
SUMMERY OF THE UTILITY MODEL
To the problem that resistant crooked life-span is poor, fragile when radio frequency cable is used as dynamic bending or test cable, the utility model provides a resistant crooked radio frequency cable, through the structural layer that changes the cable, make its structural layer have anti bending property and protect the function that cable inner structure reached increase crooked life-span.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the bending-resistant radio frequency cable comprises a cable core and an insulator layer wrapped outside the cable core, and is characterized in that a silver-plated copper strip shielding layer is wrapped outside the insulator layer, a steel wire weaving layer is mounted outside the silver-plated copper strip shielding layer, a silver-plated weaving layer is wrapped outside the steel wire weaving layer, and a sheath layer is sleeved outside the silver-plated weaving layer.
As a preferred scheme, the wire core is a silver-plated copper conductor.
Preferably, the insulator layer is a low density polytetrafluoroethylene dielectric.
As a preferred scheme, the weaving density of the steel wire weaving layer is 95% -98%.
Preferably, the sheath layer is made of insulating rubber.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses increase one deck steel wire weaving layer in silver-plated weaving layer, utilize the pliability of steel wire to increase the bending resistance of cable, support the atress each other between the steel wire mesh grid when this radio frequency cable is crooked, utilize the fine protection of elasticity of steel wire cable inner structure simultaneously, make it not take place deformation to make the cable have good resistant bending ability, the external diameter of cable can not increase by a wide margin simultaneously, the installation of being convenient for increases the life of cable simultaneously.

Detailed Description
The invention will be further described with reference to specific embodiments. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example (b):
as shown in fig. 1, a bending-resistant radio frequency cable comprises a wire core 1 and an insulator layer 2 wrapped outside the wire core 1, and is characterized in that: the insulating body layer 2 is externally wound with a silver-plated copper strip shielding layer 3, the silver-plated copper strip shielding layer 3 is externally provided with a steel wire weaving layer 4, the steel wire weaving layer 4 is externally coated with a silver-plated weaving layer 5, and the silver-plated weaving layer 5 is externally coated with a sheath layer 6.
The utility model discloses prefer sinle silk 1 be silvered copper conductor.
The insulator layer 2 is preferably a low density polytetrafluoroethylene dielectric.
The utility model discloses preferred the weaving density of steel wire weaving layer 4 be at 95% -98%.
The utility model discloses it is preferred restrictive coating 6 make for insulating rubber.
The utility model discloses a theory of operation does:
a bending-resistant radio frequency cable, the main structure of which comprises: 1: a wire core; 2: an insulator layer; 3: silver plating of a copper strip shielding layer; 4: a steel wire braid layer; 5: silver plating braid; 6: a sheath layer;
wherein, the 4 th layer of the steel wire braided layer adopts a small-pitch braiding process (the braiding density is 95-98%, and the pitch is as small as possible);
because the steel wire has good anti bending ability and elasticity, when this radio frequency cable is crooked the mutual support atress between the steel wire mesh grid, utilize the fine protection of elasticity of steel wire cable inner structure simultaneously, make it not take place deformation to make the cable have good resistant bending ability, the external diameter of cable can not increase by a wide margin simultaneously.
The 5 th layer uses a silver-plated woven layer, so that the braided layer has good welding characteristics, and good contact performance of the cable and the connector is guaranteed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
