Problems solved by technology

[0002] Passive microwave power divider, its working frequency is 650MHz, because it is a microwave device, the size is small, the method of directly welding the test line on the device is usually used for testing, when the size is small, the welding cannot be completed and it is especially easy to short circuit. There are serious deficiencies in the test method. The properties of the device itself are destroyed during the welding process, and it is time-consuming and labor-intensive. The test process is prone to errors, and it is impossible to easily complete the test of the device. At present, there is no corresponding fixture for testing.

Embodiment Construction

[0024] The invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1~Figure 7 As shown, a microwave power divider test seat includes a cavity 3, a circuit board 4, a positioning plate 5, and a pressing spring clamp 6. The cavity with an opening on the upper end of the cavity 3 is fixedly connected to the base 1, In the cavity 3, a circuit board 4 and a positioning board 5 are fixedly placed in sequence from bottom to top. The circuit board 4 is connected to the monitoring equipment through wires, and the positioning board 5 is provided with a groove 7 for placing a dispenser. The pressing piece spring fixture 6 is fixedly connected on the mounting seat 19 of the cavity 3, and is provided with a pressure rod 10 that can be elastically recovered and stretched. The position of the pressure rod 10 is directly facing the groove 7, and is made of plastic to avoid crushing the test device. The mounti...

Abstract

The invention discloses a test bench for a microwave power divider. The test bench comprises a cavity, a circuit board, a positioning plate and a tabletting spring perch. The upper end surface of the cavity is provided with an opening and is fixedly connected with a base. Inside the cavity, a circuit board and a positioning plate are successively and fixedly arranged from bottom to top. The circuit board is connected with a monitoring device via a lead. The positioning plate is provided with a groove for placing a microwave power divider. The tabletting spring perch is fixedly connected with the cavity and is provided with an elastically restorable and expandable pressing rod. The pressing rod is right facing the groove. According to the technical scheme of the invention, the microwave power divider is placed in the groove of the positioning plate, and a to-be-measured device is pressed by the elastically restorable and expandable pressing rod. The bottom pin of the device is in contact with the circuit board. Under the buffering effect of the elastically restorable and expandable pressing rod, the device is prevented from being damaged. The test bench for the microwave power divider is safe and reliable in testing, and ensures the good contact of a microwave radio-frequency transformer with a soldering pad on the test bench. Meanwhile, the power attenuation is reduced. Moreover, the test bench is simple in structure, convenient to install and lossless to devices, thus being applicable to the testing operation on products in mass production.

Description

technical field [0001] The invention belongs to the technical field of testing devices for electronic components, and relates to a test seat for a microwave power divider. Background technique [0002] Passive microwave power divider, its operating frequency is 650MHz, because it is a microwave device, its size is small, and the method of directly welding the test line on the device is usually used for testing. When the size is small, the welding cannot be completed and it is especially easy to short circuit. There are serious deficiencies in the test method. The properties of the device itself are destroyed during the welding process, and it is time-consuming and labor-intensive. The test process is prone to errors, and it is impossible to easily complete the test of the device. At present, there is no corresponding fixture for testing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a microwave power divider te...
