Description

Technical Field

[0001] The utility model relates to a comprehensive testing device for a radio frequency coaxial connector. Background Art

[0002] The measurements of various dimensions and performance indicators of RF coaxial connectors are all measured independently and in steps. The interface dimensions need to be measured manually using an altimeter, or special tooling needs to be made to measure in combination with an altimeter. The withstand voltage test of internal and external conductors requires connecting the internal and external conductors to the two poles of the test instrument respectively and then performing a pressure-raising and pressure-maintaining test. The airtight test requires the use of special tooling to inflate from the connector port or flange, and maintain the pressure after inflating to the set value. The pressure drop within a certain period of time is determined by reading the airtightness tester.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example:

[0041] like Figure 1-5 As shown, this embodiment provides a comprehensive test device for radio frequency coaxial connectors, including a test platform 10, wherein a plurality of connection seats 30 are evenly arranged on the top surface of the test platform 10, and the connection seats 30 are provided with matching connectors 50 to be tested;

[0042] A pressure plate 20 is provided on the test platform 10, and multiple groups of connectors 50 are arranged below the pressure plate 20 so that the connectors 50 are in close contact with the connection seat 30. Multiple groups of test components 40 are also evenly arranged on the bottom surface of the test platform 10. The positions of the multiple groups of test components 40 are matched with the positions of the multiple groups of connection seats 30, and are used to perform interface size, air tightness and voltage resistance performance tests on the connectors 50 on the connection seat 30.

[0043] In this embodiment, when testing the connectors 50, the pressing plate 20 is raised and the matching connectors 50 are placed on the multiple sets of connection seats 30. Then, the pressing plate 20 is lowered and the multiple sets of connectors 50 are pressed onto the multiple sets of connection seats 30 respectively by the pressing plate 20. The interface dimensions, air tightness, and voltage resistance performance of the connectors 50 on the connection seats 30 are tested by the test assembly 40 on the connection seats 30.

[0044] By setting up multiple groups of connection seats 30 and corresponding test components 40, the interface size, air tightness and voltage resistance performance tests of multiple connectors 50 can be performed at the same time, which significantly improves the test efficiency; the connector 50 is in close contact with the connection seat 30 through the pressure plate 20, which ensures the contact stability between the connector 50 and the test component 40 during the test, thereby improving the accuracy and reliability of the test results; the lifting and lowering mechanism of the pressure plate 20 makes the operation simple during the placement and pressing of the connector 50, reduces the difficulty of operation and improves work efficiency.

[0045] Specifically, a plurality of groups of downward pressure cylinders 21 are evenly arranged on the test platform 10 , and the downward pressure cylinders 21 are connected to the test platform 10 . A connecting frame 22 is provided on the piston of the downward pressure cylinder 21 , and the connecting frame 22 is connected to the pressure plate 20 .

[0046] Specifically, a plurality of guide rods 11 are evenly arranged on the test platform 10;

[0048] In this embodiment, when the pressure plate 20 presses the connector 50, the downward pressure cylinder 21 drives the pressure plate 20 to descend. At the same time, since the guide rod 11 slides in the guide sleeve 23, the guiding accuracy of the pressure plate 20 when it descends can be enhanced, ensuring the stability and accuracy of the pressure plate 20 during the descent process, thereby improving the repeatability and reliability of the test process.

[0049] Specifically, the connection seat 30 is provided with a test hole 33 , the connector 50 matches the test hole 33 , a test sealing ring 32 is provided in the test hole 33 , and the connector 50 is placed in the test hole 33 and contacts the test sealing ring 32 .

[0050] Specifically, the connecting seat 30 is provided with a connecting portion 36 , and the outer wall of the connecting portion 36 is provided with a connecting thread outer wall 35 ;

[0052] In this case, the threaded portion connected to the threaded outer wall 35 is not shown.

[0053] In this embodiment, when testing the connector 50, the connecting seat 30 that is compatible with the connector 50 is first threadedly connected to the test platform 10, that is, the connecting threaded outer wall 35 is threadedly connected to the connecting internal threaded hole 12, and then the connector 50 is placed in the test hole 33 of the connecting seat 30.

[0054] Specifically, the test assembly 40 includes a test seat 45, which matches the position of the connecting seat 30. The test seat 45 is connected to the test platform 10.

[0056] In this case, the interface dimension refers to the height difference between the end face of the inner conductor of the connector 50 and the end face of the outer conductor of the connector 50;

[0057] In this embodiment, when the interface dimension test of the connector 50 is performed, when the connector 50 is not placed on the connecting seat 30, the altimeter 422 is in a zero state. When the connector 50 is placed on the connecting seat 30, the inner conductor on the connector 50 contacts the test probe 42, and the test probe 42 is pressed down, so that a height difference is formed between the end face of the inner conductor of the connector 50, that is, the end face of the test probe 42 and the end face of the outer conductor of the connector 50. Then, the value is read by the altimeter 422 to know the size between the end face of the inner conductor of the connector 50 and the end face of the outer conductor of the connector 50. Then, the test data of each altimeter 422 is output to the computer for summary recording, eliminating the need to read the data one by one, and a test report can be generated.

[0060] In this embodiment, when testing the interface dimensions, the air tightness tester fills the air tightness test chamber 44 with a specified pressure through the air tightness tester hose 48 and the air nozzle 49. After maintaining the pressure for a period of time, the pressure difference is tested to test whether the seals at each location are airtight and reliable, and then determine whether the sealing of the connector 50 itself meets the requirements.

[0061] Of course, multiple air tightness tester hoses 48 can be connected in parallel and then connected to the air tightness tester. One air tightness tester can test multiple connectors 50 at the same time, saving costs and improving efficiency.

[0062] Specifically, the test seat 45 is further provided with a spring pin 46 , and the spring pin 46 contacts the test probe 42 ;

[0063] The connection base 30 is provided with a connection hole 34 , and a withstand voltage tester is provided between the connection hole 34 and the spring pin 46 .

[0064] Specifically, the connection socket 30 and the test probe 42 are both made of metallic conductive materials, and the test socket 45 is made of non-metallic non-conductive materials.

[0065] In this embodiment, when performing a withstand voltage test on the connector 50, one end of the withstand voltage tester is connected to the connection hole 34, and the other end of the withstand voltage tester is connected to the spring pin 46. Then, the withstand voltage tester creates a high voltage condition between the outer conductor and the inner conductor of the connector 50, and the withstand voltage performance between the inner and outer conductors of the connector 50 is tested and determined.

[0066] Of course, through circuit design, the test connection points at both ends of multiple test components 40, i.e., the connection holes 34 and the spring pins 46, can be connected in parallel and then connected to a withstand voltage tester.

[0069] The test socket 45 is further provided with a pressure-resistant mounting hole 451 . The pressure-resistant mounting hole 451 is communicated with the sliding through hole 453 . The spring pin 46 is disposed in the pressure-resistant mounting hole 451 .
