The connection structure comprises a cable and a connector main body, wherein the cable comprises a cable inner conductor and cable insulating medium wrapped on the cable inner conductor; the connector main body is internally provided with a cavity used for containing the insulating medium and the inner conductor; and the cable insulating medium and the cable inner conductor therein extend into the cavity to be connected with the connector main body. The utility model is particularly applicable to the connection of SMA-JB3 type radio frequency coaxial cables.

Description

The syndeton of radio-frequency (RF) coaxial cable

Technical field

The utility model relates to a kind of syndeton that is used for the radio-frequency (RF) coaxial cable of communications industry.

Background technology

Development along with communications industry, it is a lot of that the radio frequency (RF) coaxial connector cable-assembly is used, about 50% radio frequency (RF) coaxial connector almost, finally all to be processed into the radio frequency (RF) coaxial connector cable-assembly, and it is most of to determine in these radio frequency (RF) coaxial connector cable-assemblies, and the screen of the radio-frequency (RF) coaxial cable of usefulness is that metal wire knitted forms.

Referring to Fig. 1, Fig. 2, present coaxial cable, as SMA-JB3 type radio frequency coaxial-cable, it is connected with miscellaneous equipment or cable, needs one to be used for the excessively radio frequency (RF) coaxial connector 1 of connection.A cavity is arranged in the radio frequency (RF) coaxial connector 1, cavity is built-in with a connector dielectric 3, the areola that a placement connector inner wire 2 is arranged in the dielectric 3, what place in the areola is connector inner wire 2, and the jack 20 that inserts for cable inner wire 7 is arranged on connector inner wire 2.The place that cable 5 is connected with radio frequency (RF) coaxial connector 1 is made up of cable dielectric 6 and the cable inner wires 7 that expose outside the cable dielectric 6.Cable inner wire 7 inserts to be finished in the jacks 20 being connected of cable 5 and radio frequency (RF) coaxial connector 1.The parts that existing structure relates to are on the high side, and cost is higher.

The utility model content

Technical problem to be solved in the utility model is: a kind of syndeton of radio-frequency (RF) coaxial cable is provided, and this structure is used for being implemented under the situation that does not reduce performance, reduces cost.

In order to solve the problems of the technologies described above, the utility model proposes a kind of syndeton of radio-frequency (RF) coaxial cable, comprise cable and connector body, wherein cable comprises cable inner wire and the cable dielectric that is wrapped on the cable inner wire, the cavity that ccontaining dielectric and inner wire are arranged in the connector body, described cable dielectric with and interior cable inner wire stretch in the described cavity, be connected with described connector body.

Preferably: the diameter of described cable inner wire is 0.9mm.

Preferably: described cable inner wire is tapered with the end that described connector body docks.The cable inner wire end face of taper helps cable and good being electrically connected of radio frequency (RF) coaxial connector.

The beneficial effects of the utility model are: compare existing radio frequency (RF) coaxial connector, the beneficial effects of the utility model are the inner wire of original radio frequency (RF) coaxial connector alternative with the inner wire of cable, because it is just the same connecing the sectional dimension of the inner wire of the inner wire of cable of radio frequency (RF) coaxial connector and connector, so the dielectric of the radio frequency (RF) coaxial connector dielectric with cable can be substituted.So just save two parts in the existing product, thereby reduced the material cost and the processing cost of this product.But also the welding of radio frequency coaxial-cable inner wire in making the cable-assembly process and other undesirable elements have been reduced to the cable-assembly Effect on Performance.
