Description

[Technical field]

[0001] The utility model belongs to the technical field of RF testing devices, and in particular relates to an RF testing device capable of automatically 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. After the product to be tested 200 is pressed into the guide fixture and connected to the test connector for the continuity test, it is difficult to remove the product to be tested 200 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 automatically release the antenna to be tested and the test connector after the test is completed. In the prior art, Chinese Patent Publication No. CN219799530U discloses an RF high-frequency test fixture, in which the upper mold assembly corresponding to the position of the device to be tested will press the device to be tested downward, and then the first floating spring is compressed, driving the device to be tested and the placement plate to slide downward appropriately, so that the upper end of the detection probe can be pressed against the device to be tested; under the driving action of the buckle plate spring, the lower end of the rotating buckle plate is rotated to be inserted into the buckle groove of the lower mold mounting plate, thereby realizing the relative positioning between the upper mold assembly and the lower mold assembly; after the test is completed, the upper mold assembly can be opened by pressing the upper end of the rotating buckle plate, and then the first floating spring is extended to drive the device to be tested and the placement plate to slide upward appropriately, so that the detection probe is separated from the device to be tested, and the device to be tested that has completed the test can be taken out. Although this solution can realize the separation of the probe to be tested from the device 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 antennas or electronic products inside the machine.

[0004] Therefore, in order to solve the above problems, it is necessary to provide an RF testing device that can automatically unlock to solve the above technical problems. [Contents of the utility model]

[0005] The main purpose of the utility model is to provide an RF testing device that can be automatically unlocked, which can not only realize the rapid positioning and automatic unlocking and separation of the product to be tested and the test connector module, but also has a simple linear structure as a whole, occupies very little space, is very portable, and can be inserted into the interior of a machine to test the installed product.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: an RF test device that can be automatically unlocked, which includes a test connector module led out from a test device, a mounting base for mounting the test connector module, and a sliding card seat that is elastically floatingly arranged above the mounting base and is used to position a product to be tested; the test connector module includes a plug-in male head that is plugged and connected to the plug-in female head of the product to be tested, the sliding card seat is provided with a limiting groove for positioning the product to be tested, and the bottom of the groove at the front end of the limiting groove is provided with a first avoidance hole for avoiding the plug-in male head.

[0007] Furthermore, the test connector module also includes a test line at the lower end and an adapter fixed to the upper end of the test line and installed and positioned with the mounting seat, and the male connector is arranged at the upper end of the adapter.

[0008] Furthermore, the adapter is installed inside the mounting seat by screws, and the adapter includes a fixing section used to be fixedly mounted with the mounting seat and a limiting section located on the upper surface of the mounting seat and used to limit the sliding seat to a lower position.

[0009] Furthermore, the mounting base includes a first through hole for mounting the test connector module and a first threaded hole adapted to the screw and connected to the first through hole front and back; the mounting base is also provided with a plurality of second through holes, and the sliding base is provided with a plurality of second threaded holes corresponding to the upper and lower positions of the second through holes, and the bolts are adapted to the second through holes and the second threaded holes at the same time to realize the installation of the mounting base and the sliding base.

[0010] Furthermore, a second avoidance hole for avoiding the limiting section is formed on the lower surface of the sliding seat.

[0011] Furthermore, a plurality of elastic components are arranged between the sliding seat and the mounting seat.

[0012] Furthermore, the elastic component includes a guide rod and a spring sleeved on the outer circumference of the guide rod.

[0013] Furthermore, a plurality of first step holes are provided on the mounting seat, and a plurality of second step holes are provided on the sliding seat. The lower ends of the guide rod and the spring are movable up and down in the first step holes, and the upper ends of the guide rod and the spring are arranged in the first step holes, and the upper end of the guide rod is fixedly mounted on the sliding seat.

[0014] Compared with the prior art, the beneficial effects of the RF testing device capable of automatic unlocking of the utility model are:

[0015] (1) The sliding card seat is elastically floated up and down above the mounting seat through a number of elastic components. The sliding card seat and the antenna to be tested are pressed downward to make the plug-in female connector of the product to be tested and the plug-in male connector of the test connector module plug and connect. After the test is completed and the sliding card seat is released, the elastic component stretches to drive the sliding card seat to slide upward relative to the mounting seat, thereby driving the product to be tested to move upward and automatically unlock and separate from the test connector module. When the elastic component moves upward, the force in all directions is uniform and stable. When the mounting seat slides upward, the product to be tested is subjected to uniform force in all directions and moves upward, thereby avoiding damage to the product to be tested and the test connector module;

[0016] (2) The elastic component includes a guide rod and a spring sleeved on the outer circumference of the guide rod. The guide rod is provided to improve the stability of the spring when it is compressed and stretched, thereby ensuring the stability of the sliding seat when it slides up and down;

[0017] (3) The utility model has an overall linear structure, which not only occupies a very small space, but is also very portable. It can be rolled up and placed, 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. It is very flexible and highly versatile. Even if the antenna to be tested inside the machine is very short or the installed electronic product cannot be removed, it can be inserted into the machine to perform RF testing on the installed antenna or electronic product.

[0018] (4) The limit grooves provided on the sliding card seat can realize the rapid positioning of the product to be tested and the test connector module. The product to be tested is placed in the limit groove and pressed down to realize the plug-in connection between the plug-in female connector of the product to be tested and the plug-in male connector of the test connector module. The positioning is simple and convenient.

[0019] (5) One end of the limiting groove passes through the side of the sliding seat, so that the wire section of the product to be tested can extend out from the side of the limiting groove, thereby avoiding the phenomenon of bending and breaking of the wire section of the product to be tested.

[0020] Therefore, the automatically unlocked RF testing device provided by the present solution can not only realize the rapid positioning and automatic unlocking and separation of the product to be tested and the test connector module, but also has a simple linear structure as a whole, occupies very little space, is very portable, and can be extended into the interior of the machine to test the installed products.

[0037] Embodiment 1:

[0038] Please refer to Figure 2-Figure 8 The present embodiment is an RF test device 100 that can be automatically unlocked. The RF test device 100 that can be automatically unlocked includes a test connector module 1 led out from the test equipment, a mounting seat 2 for mounting the test connector module 1, and a sliding seat 3 that is elastically floated above the mounting seat 2 and is used to position a product 200 to be tested.

[0039] In this embodiment, the product 200 to be tested is an antenna, which includes a wire section 201 and a connector section 202 fixedly connected to the end of the wire section 201. The lower end of the connector section 202 is provided with a female connector 203 that is plugged into the test connector module 1 to achieve conduction.

[0040] The test connector module 1 includes a test line 11 at the lower end, an adapter 12 fixed to the upper end of the test line 11 and installed and positioned with the mounting seat 2, and a male plug 13 arranged on the upper surface of the adapter 12 and adapted to be plugged with the female plug 203 of the product to be tested 200 to achieve electrical conduction. The adapter 12 is installed inside the mounting seat 2 by screws 5 arranged on both sides of the mounting seat 2, thereby achieving the installation and fixation of the test connector module 1 and the mounting seat 2.

[0041] The length of the test line 11 can be adjusted according to the actual situation, so as to flexibly adapt to the distance between the product to be tested and the test instrument. The RF test device provided by this solution is an overall linear structure, which not only occupies a very small space, but is also very portable, and can be inserted into the machine to test the installed product. It can be rolled up and placed, or it can be 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. It is very flexible and highly versatile.

[0042] The adapter 12 includes a fixed section 121 for fixing with the mounting base 2 and a limiting section 122 located on the upper surface of the mounting base 2 and used to limit the lower position of the sliding base 3; the screws 5 are tightened and squeezed on the fixed section 121 from both sides of the mounting base 2 to achieve the installation and fixation of the test connector module 1 and the mounting base 2, and the upper surface of the limiting section 122 is provided with a plug-in male head 13.

[0043] The mounting seat 2 includes a first through hole 21 for mounting the test connector module 1 and a first threaded hole 22 adapted to the screw 5 and connected to the first through hole 21 from front to back. The fixed section 121 of the adapter 12 is located in the first through hole 21. The screw 5 is tightened and squeezed on the fixed section 121 from the first threaded hole 22 to achieve the installation and fixation of the test connector module 1 and the mounting seat 2. The mounting seat 2 is provided with a plurality of second through holes 23, and the sliding seat 3 is provided with a plurality of second threaded holes 34 corresponding to the positions of the second through holes 23. The bolt 6 is screwed from the second through hole 23 on the lower surface of the mounting seat 2 to the second threaded hole 34 on the sliding seat 3 to achieve the installation of the mounting seat 2 and the sliding seat 3. The upper end of the bolt 6 has a thread that matches the second threaded hole 34, and the lower end of the bolt 6 has no thread and can move up and down in the second through hole 23. This installation method can not only achieve the installation of the mounting seat 2 and the sliding seat 3, but also facilitate the sliding of the sliding seat 3 up and down.

[0044] A limiting groove 31 for positioning the product to be tested 200 is provided on the sliding seat 3, and a first avoidance hole 32 for avoiding the plug-in male connector 13 is provided at the bottom of the front end of the limiting groove 31; the upper end of the connector section 202 of the product to be tested 200 is restricted in the limiting groove 31 and pressed downward, so that the plug-in female connector 203 of the product to be tested 200 is engaged with the plug-in male connector 13 of the test connector module 1 and realizes electrical conduction.

[0045] The limiting groove 31 arranged on the sliding holder 3 can realize the rapid positioning of the product to be tested 200 and the test connector module 1; one end of the limiting groove 31 passes through the side of the sliding holder 3, so that the product to be tested 200 can be inserted into the limiting groove 31, and the wire section 201 of the product to be tested 200 can extend out from the side of the limiting groove 31, thereby avoiding the phenomenon of bending and breaking of the wire section 201 of the product to be tested 200.

[0046] The lower surface of the sliding seat 3 is also provided with a second avoidance hole 33 for avoiding the limiting section 122 of the adapter 12. When the sliding seat 3 is pressed downward into place, the limiting section 122 of the adapter 12 extends into the second avoidance hole 33 and the upper surface of the limiting section 122 abuts against the lower hole wall of the second avoidance hole 33 to limit the sliding seat 3 downward. At the same time, the plug-in male connector 13 extends into the first avoidance hole 32 and is located in the limiting groove 31 to be plugged and adapted to be conductive with the plug-in female connector 203 of the product 200 to be tested.

[0047] The sliding seat 3 can be elastically floated up and down and is arranged above the mounting seat 2. This is because a number of elastic components 4 are arranged between the sliding seat 3 and the mounting seat 2. The elastic component 4 includes a guide rod 41 and a spring 42 sleeved on the outer periphery of the guide rod 41. The guide rod 41 is arranged to improve the stability of the spring 42 during compression and extension; a number of first step holes 24 are arranged on the mounting seat 2, and a number of second step holes 35 are arranged on the sliding seat 3. The lower ends of the guide rod 41 and the spring 42 can move up and down and are located in the first step hole 24. The upper ends of the guide rod 41 and the spring 42 are arranged in the first step hole 34 and the upper end of the guide rod 41 is fixed to the sliding seat 3. After the test is completed, the sliding holder 3 is released and the spring 42 stretches to drive the sliding holder 3 to slide upward relative to the mounting seat 2, thereby driving the product to be tested 200 to move upward and automatically unlock and separate from the test connector module 1. When the spring 42 moves upward, the force in all directions is uniform and stable. When the mounting seat 2 slides upward, the product to be tested 200 is subjected to uniform force in all directions and moves upward, thereby avoiding damage to the product to be tested 200 and the test connector.

[0048] The working principle of the RF testing device 100 that can be automatically unlocked in the present scheme is as follows: the product 200 to be tested is placed in the limiting groove 31 of the sliding card seat 3, the upper end of the connector section 202 of the product 200 to be tested is limited in the limiting groove 31, and the product 200 to be tested and the sliding card seat 3 are pressed downward at the same time, the limiting section 122 of the adapter 12 extends into the second avoidance hole 33 and the upper surface of the limiting section 122 abuts against the lower hole wall of the second avoidance hole 33 to limit the sliding card seat 3 downward, and at the same time, the plug-in male connector 13 extends into the first avoidance hole 32 and is located in the limiting groove 31 and is plugged and adapted to be connected with the plug-in female connector 203 of the product 200 to be tested, or the sliding card seat 3 is pressed downward first, and the limiting section 122 of the adapter 12 extends into the second avoidance hole 33. The upper surface of the limiting section 122 is in the hole 33 and abuts against the lower hole wall of the second avoidance hole 33 to limit the sliding seat 3 downward, and at the same time, the plug-in male head 13 extends into the first avoidance hole 32 and is located in the limiting groove 31, and then the product 200 to be tested is placed in the limiting groove 31, and the product 200 to be tested is pressed downward to make the plug-in female head 203 of the product 200 to be tested plug-in and adapt to the plug-in male head 13 for connection. Both of these two connection operation modes are possible and can be operated according to actual conditions; after connection, the relevant test is started. After the test is completed, the sliding seat 3 is released and the spring 42 is stretched to drive the sliding seat 3 to slide upward relative to the mounting seat 2, thereby driving the product 200 to be tested to move upward and automatically unlock and separate from the test connector module 1, completing this test.
