[0002] With the advancement of science and technology, integration is getting higher and higher, the size of RF modules is getting smaller and smaller, and the models are diversified. There is no extra space next to the RF terminal to drill the connector grounding hole, which is extremely inconvenient to test such products. In addition, the customization requirements of the modules are high, and the number of single products is small. Generally, companies cannot pile up costs on automated production lines and automated fixtures. Most of the existing fixtures use non-metallic material blocks to directly press the pins and structural parts of the module to be tested, which can easily cause scratches on the module and pins, and most of the blocks are locked with screws, which has low test efficiency. In addition, when using customized chemical equipment for testing, specific tooling is customized for each RF module, which increases the tooling cost, so it needs to be improved. Utility Model Content

[0004] The radio frequency module testing tool comprises a base, a fixing seat is arranged on the base, the fixing seat is connected to the base through a spring column, vertical spur teeth are arranged on the side of the fixing seat, hooks are arranged on the table surface of the base corresponding to the spur teeth, the hooks are movably engaged with the spur teeth, a positioning ring for positioning the radio frequency module to be tested is detachably installed on the upper end surface of the fixing seat, a connector seat is also arranged on the base, two connector seats are symmetrically arranged on both sides of the fixing seat, and a test head for electrically connecting to the radio frequency module is arranged on the connector seat.
[0005] Preferably, a guide rail is provided on the base, and the connector seat is movably mounted on the guide rail and performs reciprocating linear motion along the guide rail.
[0006] Preferably, an elastic component is also provided at the upper end of the connector seat, and the elastic component includes a guide column, a spring and a knob. One end of the guide column is fixedly inserted in the fixed seat, and the other end of the guide column movably passes through the connector seat. The spring is sleeved on the guide column, and both ends of the spring are respectively abutted against the fixed seat and the connector seat. The knob is threadedly connected to one end of the guide column passing through the connector seat, and the knob abuts against the surface of the connector seat.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0016] like Figures 1-2As shown, the RF module testing tooling includes a base 1, on which a fixing seat 2 is arranged, and the fixing seat 2 is connected to the base 1 through a spring column, and the side of the fixing seat 2 is provided with vertical spur teeth 21, and a hook 11 is arranged on the table surface of the base 1 corresponding to the spur teeth 21, and the hook 11 is movably engaged with the spur teeth 21, and a positioning ring 3 for positioning the RF module 100 to be tested is detachably installed on the upper end surface of the fixing seat 2, and a connector seat 4 is also arranged on the base 1, and two connector seats 4 are symmetrically arranged on both sides of the fixing seat 2, and a test head 5 for electrically connecting to the RF module 100 is arranged on the connector seat 4. Specifically, in this embodiment, our base 1 is made of bakelite, and the fixing base 2 is made of metal. The fixing base 2 is installed on the base 1 through a number of spring columns, so that the fixing base 2 is floatingly set on the base 1. In order to achieve the purpose of adjustable height of the fixing base 2, we set straight teeth 21 on the left and right sides of the fixing base 2. The straight teeth 21 are detachably connected and matched with the hook 11, thereby adjusting the suspension height of the fixing base 2, and then adjusting the height of the RF module 100 to be tested placed on the fixing base 2, so that RF modules 100 to be tested of different volumes can all be adapted to the test head 5 of a certain height without the need to design customized tooling. At the same time, we set two connector seats 4 on the front and back sides of the fixing base 2. The connector seat 4 is equipped with a test head 5 electrically connected to the RF module 100 to be tested. The test head 5 is electrically connected to the background test instrument through a cable to complete the test. It should be noted that because the sizes of the RF modules 100 to be tested are different, in order to align the connector of the RF module 100 to be tested with the test head 5, we have detachably installed a positioning ring 3 on the fixed seat 2, which can horizontally locate the position of the RF module 100 to be tested, so as to facilitate subsequent testing of the RF modules 100 to be tested of the same batch model, improve test efficiency, and do not need to replace tooling, thereby reducing tooling costs.
[0017] like Figures 1-2 As shown, the base 1 is provided with a guide rail 12, and the connector seat 4 is movably mounted on the guide rail 12 and performs reciprocating linear motion along the guide rail 12. Specifically, the connector seat 4 is mounted through the guide rail 12, so that the distance between the test head 5 and the RF module 100 to be tested is adjustable, and the RF modules 100 to be tested of different volumes are adapted, and the test, disassembly, and removal are more convenient, so as to avoid the test heads 5 on both sides clamping the RF module 100 to be tested after the test, which is difficult to replace.
[0018] like Figure 3As shown, an elastic component 6 is also provided at the upper end of the connector seat 4, and the elastic component 6 includes a guide column 61, a spring 62 and a knob 63. One end of the guide column 61 is fixedly inserted in the fixing seat 2, and the other end of the guide column 61 is movable through the connector seat 4. The spring 62 is sleeved on the guide column 61, and the two ends of the spring 62 are respectively abutted against the fixing seat 2 and the connector seat 4. The knob 63 is threadedly connected to one end of the guide column 61 that passes through the connector seat 4, and the knob 63 is abutted against the surface of the connector seat 4. Specifically, the elastic component 6 is provided between the connector seat 4 and the fixing seat 2, and the knob 63 is threadedly connected to the end of the guide column 61. By screwing the knob 63, the depth of the knob 63 inserted into the port of the guide column 61 can be adjusted, thereby compressing the spring 62 or stretching the spring 62, thereby adjusting the distance between the fixing seat 2 and the connector seat 4, so that the distance between the test head 5 and the RF module 100 to be tested can be fine-tuned very conveniently and quickly.
[0019] Specifically, the positioning ring 3 is magnetically adsorbed on the end face of the fixing seat 2, which facilitates the adjustment of the position of the positioning ring 3, and then adjusts the position of the RF module 100 to be tested, so that it is aligned and plugged with the test head 5 on the connector seat 4 to ensure good electrical connection.
[0020] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
