Description

Technical Field

[0001] This utility model relates to the field of aging test technology for radio frequency power dividers, and in particular to an aging test fixture for radio frequency power dividers. Background Technology

[0002] Radio frequency (RF) power divider aging test (also known as RF power divider burn-in test) is an aging test of RF power dividers, which is a test method to evaluate the reliability and performance changes of RF power dividers during long-term use. Currently, there is no corresponding test fixture equipment in the existing technology, and it still adopts the method of manually connecting test leads, which has low test efficiency.

[0003] Therefore, there is an urgent need to propose a simple and reliable test fixture for RF power dividers. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a aging test fixture for radio frequency power dividers. The technical solution adopted by this utility model is as follows:

[0005] A radio frequency power divider aging test fixture is provided for holding the radio frequency power divider to be tested. It includes a lower mounting plate, several support feet fixed to the bottom of the lower mounting plate, a power divider mounting plate mounted on the lower mounting plate, several radio frequency power divider mounting sockets fixed on the power divider mounting plate, and a first coaxial connector and a second coaxial connector mounted on the power divider mounting plate and electrically connected to the radio frequency power divider mounting sockets. The radio frequency power divider to be tested is placed inside the radio frequency power divider mounting sockets.

[0006] The RF power divider mounting socket includes a lower support fixed to the power divider mounting plate, an electrical connection socket assembly embedded in the lower support and electrically connected to the first coaxial connector and the second coaxial connector, an RF power divider mounting slot opened in the electrical connection socket assembly, an upper socket cover plate connected to the lower support plate on one side by a pivot, and a latch located on the other side of the upper socket cover plate and fastened to the lower support plate; the upper socket cover plate covers the RF power divider to be tested in the electrical connection socket assembly.

[0007] Furthermore, a pressing block is fitted inside the upper socket cover; a pressing knob is provided on the upper socket cover; the pressing knob is threadedly connected to the upper socket cover, and the pressing knob presses and adjusts the pressing block; several knob protrusions are provided on the top of the pressing knob.

[0008] Furthermore, several heat sinks are provided at the bottom of the lower mounting plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] (1) This utility model includes a radio frequency power divider mounting socket, a first coaxial connector, and a second coaxial connector, wherein the first coaxial connector is the common terminal and the second coaxial connector is for each branch channel. This utility model also includes a lower support base, an electrical connection socket assembly, an upper socket cover, and a latch, which clamp the radio frequency power divider to be tested, making its installation and disassembly convenient and reliable.

[0011] (2) This utility model provides a pressure block and a squeezing knob to facilitate squeezing of the RF power divider to be tested, thereby ensuring reliable contact between the RF power divider to be tested and the electrical connection socket assembly.

[0012] (3) The present invention has a heat sink at the bottom of the lower mounting plate. Since the radio frequency power divider generates a lot of heat during operation, it uses the heat sink to enhance heat dissipation.

[0013] In summary, this utility model has the advantages of simple structure and reliable installation, and has high practical and promotional value in the field of RF power divider aging test technology. Attached Figure Description
