[0002] A network analyzer is a comprehensive microwave measurement instrument that can perform scanning measurements over a wide bandwidth to determine network parameters. Its full name is microwave network analyzer. To ensure the accuracy of network analyzer testing, test fixtures are usually required to provide standardized connection interfaces for the device under test (DUT) and ensure the integrity of signal transmission and measurement accuracy.

[0003] During the use of the test fixture, the wire core needs to be pressed onto the gold fingers of the PCB board to fix it in the fixture slot for measurement. However, due to the single shape of the existing fixed slot, it is not possible to measure wires of different diameters. At the same time, due to the aging of the gold fingers and the wear of the pressing parts, there is a risk of poor performance and poor contact, which will affect the final test results. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, which are limited by the single shape of existing fixed slots and the inability to measure wires of different diameters, and the risk of poor performance and poor contact due to aging of gold fingers and wear of pressing parts, thus affecting the final test results, this utility model proposes a rapid test fixture for network analyzers with adjustable fixture slots.

[0024] The moving mechanism 2 includes a wire pressing module 201 and a positioning plate 202. The inner cavity of the wire pressing module 201 is slidably connected to the surface of the guide rod 5. The bottom of the positioning plate 202 is attached to the top of the base 1. A wire groove 217 is provided on the top of the wire pressing module 201. The inner cavities of the wire pressing module 201, the positioning plate 202 and the limiting plate 3 are all threadedly connected with connecting rods 203. There are several connecting rods 203.

[0025] Reference Figure 3 and Figure 4The top of the positioning plate 202 is provided with a positioning groove 216. The inner cavity of the positioning groove 216 is fitted with a device end interface 208. A striker 213 is provided on the right side of the inner cavity of the device end interface 208. By setting the positioning groove 216, the surface of the device end interface 208 can be fitted into the interior of the positioning plate 202, which facilitates the replacement of the device end interface 208 and the striker 213 and improves the maintenance efficiency.

[0026] Reference Figure 1 and Figure 2 A fixed shaft 209 is fixedly connected to the top of the positioning plate 202. A positioning seat 204 is rotatably connected to the surface of the fixed shaft 209. The inner cavity of the positioning seat 204 is fitted onto the surface of the device end interface 208. The bottom of the positioning seat 204 is in contact with the top of the positioning plate 202. The fixed shaft 209 supports the position of the positioning seat 204. When the positioning seat 204 is closed, it can position the device end interface 208 and prevent the device end interface 208 from shifting during use.

[0027] Reference Figure 1 and Figure 2 The inner cavity of the positioning seat 204 is fitted with a fixing bolt 207. The surface of the fixing bolt 207 is threadedly connected to the inner cavity of the positioning plate 202. The position of the positioning seat 204 is fixed by the fixing bolt 207 to ensure the stability of the positioning seat 204 when it is closed and to ensure the stable use of the equipment end interface 208.

[0028] Reference Figure 2 and Figure 3 The top of the wire pressing module 201 is fixedly connected to a fixing base 215, and the inner cavity of the fixing base 215 is fixedly connected to a support shaft 214. The surface of the support shaft 214 is rotatably connected to a wire fixing hinge 205. The bottom of the wire fixing hinge 205 is in contact with the top of the wire pressing module 201. The fixing base 215 supports the position of the support shaft 214. The support shaft 214 allows the wire fixing hinge 205 to rotate on the top of the wire pressing module 201, thereby fixing the wire inside the wire groove 217 and preventing the wire from coming off the inside of the wire groove 217 during use.

[0029] Reference Figure 2 and Figure 3The top of the wire pressing module 201 is rotatably connected to a movable ring 210. A connecting plate 211 is fixedly connected to the left side of the movable ring 210. A lever 212 is fixedly connected to the left side of the connecting plate 211. The bottom of the lever 212 is in contact with the top of the wire pressing module 201. The movable ring 210 can drive the connecting plate 211 to rotate on the top of the wire pressing module 201. The connecting plate 211 can drive the lever 212 to rotate, thereby pressing the bottom of the lever 212 against the top of the wire fixing hinge 205, thus fixing the position of the wire fixing hinge 205 and ensuring the wire fixing effect.

[0030] Reference Figure 3 A support rod 206 is inserted into the inner cavity of the movable ring 210. The surface of the support rod 206 is threadedly connected to the inner cavity of the wire pressing module 201. The position of the movable ring 210 is positioned by the support rod 206 to prevent the position of the movable ring 210 from shifting during rotation, thereby affecting the normal use of the lever 212.

[0031] Working principle: When it is necessary to replace the wire pressing module 201 of different sizes, first remove it from the inside of the wire pressing module 201, positioning plate 202 and limiting plate 3 by rotating the connecting rod 203, and remove the fixing of the positioning plate 202. Then, hold the positioning plate 202 and move it to the left to remove the positioning plate 202 from the top of the base 1. Finally, hold the wire pressing module 201 and move it to the left to remove the wire pressing module 201 from the surface of the guide rod 5, which is convenient for replacing the wire pressing module 201. This eliminates the limitations of the fixed slot. By using a customized wire pressing module 201, the problem of poor contact caused by the size of the wire slot 217 leading to inadequate wire fixing is solved. Furthermore, through the setting of the device end interface 208 and the impact pin 213, the impact pin 213 contacts the wire core conductor, better preserving the integrity of the core wire and avoiding performance differences caused by frequent wear and aging of the PCB board gold fingers and deformation of the wire structure due to compression.

[0032] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
