Background technique
With electronic communication and the high speed development of network, the screen of the cable between electronic equipment internal or electronic equipment is connected
Performance is covered just to receive more and more attention.Cable has antenna effect, it both can also can receive signal with radiation signal.
When signal is radiated by cable, other electronic equipments can be formed and be interfered；Cable receives the garbage signal of electronic equipment transmitting again
System can be interfered.With the continuous raising of working frequency in electronic communication network, this interference and the just serious shadow of radiation
Ring the performance for the system of arriving.
In order to improve the anti-interference ability of cable, reduces the pollution to periphery electromagnetic environment, do not lost using shielded cable
For a kind of simple and effective method.Shielded cable can both prevent the leakage of cable internal signal, and can prevent outer
Portion's interference signal enters inside cable.The shielding properties of shielded cable is generally measured with the shielding attenuation of cable, it is characterization
The important indicator of coaxial line Electro Magnetic Compatibility.
Transfger impedance is the characteristic parameter measured external electromagnetic field energy and penetrate cable shield.In many cases, special
When not being that frequency is relatively low, the shielding attenuation of transfger impedance intermediate description shielded cable can be used, transfger impedance is lower, screen
The shielding properties for covering cable is better.
In the measurement of existing transfger impedance, usually there is the phenomenon of measurement inaccuracy, the radio frequency produced is connected
The quality for connecing device causes very big influence, so, develop the measuring machine structure of the transfer resistance impedance of a radio frequency connector
It must go.
Summary of the invention
The technical problem to be solved in the invention is a kind of radio frequency (RF) coaxial connector proposed in view of the above technical problems
Three coaxial test macros, it is simple to operate, measuring accuracy is high, ensure that the shielding properties of radio frequency connector, it improves and penetrates
The service efficiency of frequency connector.
In order to solve the above technical problems, the present invention provides a kind of three coaxial test macros of radio frequency (RF) coaxial connector, it is main
It will be by signal generator, test receiver, tested cable, sheath, first sleeve, the second casing, cable shield, first resistor
It is formed with second resistance；The tested cable is plugged in first sleeve, and the outside that cable is tested in the first sleeve surrounds
Be provided with sheath, the cable shield is arranged in one end of tested cable, the first resistor and second resistance be connected on by
One end of cable is surveyed, second casing surrounds one end that tested cable is arranged in, and the signal generator setting is in tested electricity
The side of first sleeve is arranged in the side of cable, the test receiver connection.
Further, in above-mentioned technical proposal, second casing surrounds the periphery that first resistor is arranged in.
Further, in above-mentioned technical proposal, the tested cable is also surrounded close to one end of signal generator to be provided with
Sheath.
Further, in above-mentioned technical proposal, the periphery of the first resistor is additionally provided with tail portion fixture nut.
After adopting the above structure, the shielding properties of radio frequency (RF) coaxial connector can be accurately measured, RF coaxial is improved
The quality and service efficiency of connector.
