Description

[Technical field]

[0001] The utility model belongs to the technical field of RF testing devices, and in particular relates to a handheld RF testing device capable of realizing rapid positioning and automatic unlocking. [Background technology]

[0002] When the antenna or electronic product inside the machine needs to be tested, the antenna to be tested is very short or the installed electronic product cannot be removed, so it cannot be extended outside the machine and placed on the test device for RF testing. A portable RF test device is specially designed for testing. As shown in FIG. (1), the portable RF test device 800 is a linear structure as a whole, including a test connection line 801 and a test connector 802 for conducting a test with the product to be tested 200. The portable RF test device 800 is very simple and can be rolled up or unfolded according to the length. The specific length can be determined according to the distance between the product to be tested and the test instrument. Therefore, 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 be extended into the machine to perform RF testing on the installed antenna or electronic product. However, there is a problem with this solution. The antenna to be tested needs to be manually pressed into the guide fixture to connect with the test connector. After the test is completed, it is difficult to remove the antenna to be tested from the test connector. Manual removal is not only difficult, but also may cause damage to the antenna to be tested and the test connector due to uneven pulling force or pulling in all directions, which may damage the antenna or affect the next RF test due to damage to the test connector.

[0003] Therefore, it is necessary to design a device that can realize the automatic connection and automatic release of the antenna to be tested and the test connector. In the prior art, China Patent Publication No. CN212780898U discloses a fixture that can test multiple electronic tags RF. Before the test, the tag is first slid down from the opening into the slide slot, and then the tag is fixed inside the installation frame, and then the shaft rotates to drive the cover plate to merge downward. When the installation frame is placed in the test slot, the tag contacts the upper surface of the support plate, and then the rear end of the support plate is pressed down to make the copper spring contact with the test pin. At this time, the spring under the support plate contracts, so as to perform an identification test on the tag. After the test is completed, the switch is pressed to start the electric push rod to drive the cover plate to move upward, and then the cover plate is opened to slide the tag upward from the opening. Although this solution can realize the automatic contact and separation of the test pin with the antenna to be tested, and there is no need to manually press to achieve contact and conduction between the two or to manually pull out the antenna to be tested, the test fixture provided by this solution has a complex structure and occupies a large space, which is not convenient for testing the antenna or electronic products inside the machine.
