Problems solved by technology

[0003] At present, when using testing equipment to test RF PCB terminal connectors, most manufacturers use the traditional "back-to-back" testing method, such as figure 1 As shown, the so-called "back-to-back" test method is to connect two RF PCB connectors back-to-back to form an adapter structure, and then the two signal transmission interfaces of the testing equipment are respectively connected to the two interfaces of the adapter , so that it forms a closed loop, and performs parameter detection on the adapter. The detection parameters include impedance, voltage standing wave ratio, insertion loss, etc. However, the RF PCB end connector still needs to be installed on the PCB board in the end, and it is detected in this way The results, the data results obtained are often idealized results, not the actual test results of the parameters after the PCB board is finally installed
Therefore, the data measurement results of the "back-to-back" test are not completely consistent with the application of the actual product, and cannot represent the test results of the actual application

Embodiment 1

[0050] The embodiment of the present application discloses a radio frequency PCB terminal connector.

[0051] refer to figure 2 , a radio frequency PCB terminal connector, including a base body 1 and a cylinder body 2, the base body 1 and the cylinder body 2 are integrally formed, and the whole is a "T"-shaped structure, and its material can be aluminum alloy, through the aluminum alloy The formed seat body 1 and cylinder body 2 have good rigidity and anti-rust effect, are light in weight, have good processability and mechanical properties, and are convenient for docking with other connectors, and a first columnar hole is opened through the seat body 1 11. There is a second columnar hole 21 penetrating through the column body 2, the first columnar hole 11 and the second columnar hole 21 are connected, and connecting protruding shafts are installed in the first columnar hole 11 and the second columnar hole 21 3. The shaft body part of the connecting protruding shaft 3 is loca...

Embodiment 2

[0060] In this embodiment, the difference from Embodiment 1 lies in the difference in the electrical connection portion 74 and the difference in the bottom feature of the RF PCB connector.

[0061] In this embodiment, the electrical connection part 74 can be laid in the form of microstrip lines. In order to better install the RF PCB end connector, a wire groove is provided at the bottom of the RF PCB end connector, and the microstrip line Extend from the wire groove and assemble with the embedded protruding shaft 73, and the top of the embedded protruding shaft 73 is electrically connected with the bottom end of the connecting protruding shaft 3 of the RF PCB connector.

Embodiment 3

[0063] In this embodiment, the difference from other embodiments lies in that the installation position of the installation part 72 is different, and the installation position of the RF PCB end connector is different.

[0064] In this embodiment, the mounting portion 72 is set on the side of the PCB motherboard 71 , so the RF PCB end connector can be installed on the side of the PCB motherboard 71 .

Description

technical field [0001] The present application relates to the field of electronic communication detection equipment, in particular to a radio frequency PCB end connector parameter test fixture. Background technique [0002] With the rapid development of communication technology and semiconductor technology, higher and higher requirements are placed on the frequency and rate of transmission signals. As we all know, RF PCB terminal connectors are used as test ports, and common test port interface types include SMA, 3.5mm, 2.92mm, 2.4mm, 1.85mm, SMP, SSMP, etc. These test ports themselves also need to be tested and measured, so as to ensure that their performance meets the expected specification requirements and reduce subsequent errors in the detection of transmitted signals. [0003] At present, when using testing equipment to test RF PCB terminal connectors, most manufacturers use the traditional "back-to-back" testing method, such as figure 1 As shown, the so-called "back...
