Description

technical field [0001] The invention relates to the field of radio frequency detection fixtures, in particular to a radio frequency detection connector and a radio frequency detection fixture. Background technique [0002] Radio frequency (RF) is the abbreviation of Radio Frequency, which means the electromagnetic frequency that can be radiated into space, and the frequency range is from 300kHz to 300GHz. Radio frequency is radio frequency current, referred to as RF, which is an abbreviation of high-frequency alternating electromagnetic waves. The alternating current that changes less than 1,000 times per second is called low-frequency current, and the one that changes more than 10,000 times is called high-frequency current, and radio frequency is such a high-frequency current. When using a radio frequency detector, such as a network analyzer, to perform radio frequency detection on antenna and cable products, since the radio frequency detector cannot be directly connected ...

Problems solved by technology

[0003] However, the pogo pin connector has a large radio frequency transmission loss due to the following reasons, which is not enough to meet the accuracy requirements of radio frequency detection

[0004] First, see figure 2 , the structure of the pogo pin connector 20 is relatively complex, and there are many components, which include a coaxial high-frequency connector 250, a signal line 240, a circuit board 230, a spring 220 and an elastic detection needle 210 connected in sequence, and the elastic detection needle 210 is used For connecting antenna and cable products, the coaxial high-frequency connector 250 is used to connect to a network analyzer. The radio frequency signal generated by the antenna cable product needs to pass through the elastic detection pin 210, the spring 220, the circuit board 230, the signal line 240 and the coaxial high-frequency connector 250 In order to reach the network analyzer, there will be reflections between the components due to impedance mismatch. The more components of the connector, the greater the reflection, the smaller the return loss, the lower the RF transmission power, and the longer the transmission line , the greater the attenuation of high-frequency radio frequency, the greater the radio frequency transmission loss of the pogo pin connector with five different components

[0005] Second, since the elastic detection pin of the pogo pin connector is composed of pure copper wires, there are no other supporting insulating objects to separate the copper wires, resulting in a single elastic detection pin of the pogo pin connector can only be a single wire

[0007] To sum up, due to the complex structure of the pogo pin connector, there are many components, the transmission line is long, and the transmission line is single, resulting in a small return loss, a large attenuation of high-frequency radio frequency, and low radio frequency transmission power. , the radio frequency transmission loss is relatively large, which leads to the inaccurate detection results of the radio frequency generated by the radio frequency detector for antenna and cable products
