[Technical field]

[0001] The utility model belongs to the technical field of RF testing devices, in particular to a portable RF testing device. [Background technology]

[0002] In order to improve the efficiency of RF testing, a test fixture specifically for RF testing is designed. The antenna to be tested or the electronic product to be tested is first placed on the positioning test fixture, and then the antenna or the electronic product is subjected to RF testing through the test equipment. For example, Chinese Patent Publication No. CN204086426U discloses an electronic tag RF test fixture, which includes a support frame, a carrier plate is provided on the top of the support frame, a positioning groove is provided on the carrier plate, the electronic tag to be tested is placed in the positioning groove, and a copper spring and a test pin electrically connected to the test system are provided on the bottom surface of the positioning groove; for example, Chinese Patent Publication No. CN219087273U discloses a push-pull RF test fixture, which includes a base, a support frame arranged on the base, a coupling plate arranged on the support frame, and a positioning fixture for placing the product to be tested arranged below the coupling plate.

[0003] The test fixtures in the above two patent documents can realize the positioning and testing of the product to be tested. The test device is installed in a certain position, and then the antenna or electronic product to be tested is placed on the test fixture to perform RF testing on the antenna or electronic product in batches. However, if it is necessary to perform RF testing on the antenna or electronic product installed inside the machine, because the antenna to be tested is very short or the installed electronic product cannot be removed, it cannot be extended outside the machine to be placed on the test device for RF testing. Due to the small space inside the machine, the test device in the prior art cannot be extended into the machine to perform RF testing on the installed antenna or electronic product due to its complex structure and large overall space occupied.

[0004] Therefore, it is necessary to provide a portable RF testing device to solve the above technical problems. [Contents of the utility model]

[0005] The main purpose of the utility model is to provide a portable RF testing device, which has a simple overall structure and is linear, not only occupies a very small space, but is also very portable and can be inserted into a machine to test the installed products.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a portable RF test device, which includes a test line connected to a test instrument, a test connector fixed at the upper end of the test line and electrically connected to the test line, and a guide fixture fixed at the upper end of the test connector and used for guiding the position of an antenna to be tested; the test connector includes a contour positioning ring arranged on the upper surface and contoured with the lower end of the connector section of the antenna to be tested, and a test probe arranged inside the contour positioning ring and electrically connected to the antenna; the guide fixture includes a mounting hole that passes through the lower surface and is used to install the test connector, a contour guide groove arranged on the upper surface and used for contouring the connector section of the antenna to be tested, and an avoidance hole arranged at the front end of the bottom of the contour guide groove and used to avoid the contour positioning ring.

[0007] Furthermore, the outer side wall of the contoured positioning ring is provided with an annular groove for realizing snap-fitting and positioning with the connector section of the antenna to be tested.

[0008] Furthermore, one end of the contoured guide slot passes through the side of the guide fixture, so that the wire section of the antenna to be tested can extend out from the side of the contoured guide slot.

[0009] Furthermore, a plurality of threaded holes are provided on the side of the guide fixture, and the guide fixture is fixed to the test joint by a plurality of bolts.

[0010] Compared with the prior art, the portable RF testing device of the utility model has the following beneficial effects:

[0011] (1) The RF test device provided by this solution has an overall linear structure, which not only takes up very little space but is also very portable. It can be rolled up or unfolded according to length. The specific length can be determined according to the distance between the product being tested and the test instrument. It is very flexible and highly versatile.

[0012] (2) Even if the antenna to be tested inside the machine is very short or the installed electronic product cannot be removed, the RF test device can reach into the machine to perform RF testing on the installed antenna or electronic product;

[0013] (3) The guide fixture can realize the rapid positioning of the antenna to be tested and the test connector. The antenna to be tested is placed in the contoured guide groove of the guide fixture and pressed down to realize the connection between the antenna to be tested and the test connector. The positioning is simple and convenient.

[0014] (4) One end of the contoured guide groove passes through the side of the guide fixture, so that when the antenna to be tested is inserted into the contoured guide groove to achieve positioning of the antenna to be tested, the wire section of the antenna to be tested can extend out from the side of the contoured guide groove, thereby preventing the wire section of the antenna to be tested from bending or breaking.

[0015] Therefore, the portable RF test device provided by the present solution has a simple linear structure, which not only occupies a very small space but is also very portable and can be inserted into a machine to test the installed products.
