Description

Technical Field

[0001] This utility model relates to the field of radio frequency cable assembly technology, and in particular to a simple radio frequency cable assembly vibration testing device. Background Technology

[0002] Radio frequency (RF) cable assemblies are core connection components in aerospace, electronic communications, and military equipment. Their electrical continuity under vibration directly affects the reliability of the entire equipment. According to the national military standard GJB 1215B-2021 "General Specification for Radio Frequency Cable Assemblies," cable assemblies must pass vibration and shock tests in the X, Y, and Z directions. Therefore, vibration testing equipment has become a key piece of equipment in production testing and R&D verification, widely used in component manufacturing plants, research institutes, quality inspection agencies, and other scenarios to simulate the vibration environment of cable assemblies under actual working conditions and monitor whether the electrical continuity of their inner and outer conductors meets the standards.

[0003] After exploration and analysis, the following drawbacks were found in actual use: RF cable assemblies for different applications are often equipped with connectors of different models and outer diameters. However, some existing test devices require dedicated test devices for each type of connector, which not only increases the cost of equipment procurement and storage, but also requires disassembling and replacing the entire fixing structure when changing test objects. This is cumbersome and time-consuming, and seriously affects test efficiency.

[0004] In summary, this application proposes a simple vibration testing device for radio frequency cable assemblies to solve the aforementioned problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a simple vibration testing device for radio frequency cable assemblies, comprising: The mounting plate has a through hole on its top, and a modular adapter slot is provided on the top of the through hole. The adapter component is mounted on the mounting plate and the modular adapter bracket. The adapter component includes a movable plate, a spring, a slot, a T-shaped block, and a connecting post. A spring is fixedly installed on one side of the movable plate. A sliding groove is provided at the bottom of the modular adapter bracket. A connecting post is slidably installed in the sliding groove. A T-shaped block is fixedly installed at the bottom of the connecting post. A limit groove is provided on one side of the slot.

[0007] Preferably, the top of the modular adapter card has a through hole that is connected to the top of the adapter card. An RF connector is installed in the through hole and the through hole of the modular adapter card. The design of the connected through hole ensures that the RF connector is installed accurately and can be quickly connected to the cable assembly to be tested. As the core of electrical signal transmission, the RF connector provides a stable connection interface for subsequent electrical continuity monitoring.

A connecting post is slidably installed inside the slot, allowing the user to replace and adjust the socket as needed, thereby saving storage and operating space. This flexibility is very suitable for occasions that require frequent vibration tests of different connectors. RF connectors with different outer diameters usually require different sockets for adaptation. By using a modular adapter socket, the socket can be flexibly replaced according to different RF connector outer diameters, thereby ensuring wide compatibility of the device.

[0009] Preferably, the RF connector end of the modular adapter card is welded with a wire, and a protective sleeve is provided at the connection between the RF connector and the wire. The other end of the wire is connected to the vibration / shock equipment. The welded connection between the wire and the RF connector ensures stable electrical signal transmission and meets the electrical continuity monitoring requirements of the national military standard. The protective sleeve can cover the welded joint to prevent the solder joint from falling off or the wire from being damaged during vibration.

[0010] Preferably, an insulating bushing is provided inside the through hole, which not only isolates electromagnetic interference but also buffers the impact force on the connector during vibration, thus extending the service life of the connector.

[0011] Preferably, the conductor is a shielded conductor, and the shielding layer adopts a tin-plated copper wire braided structure, which can effectively isolate electromagnetic interference in the vibration test environment, avoid external interference signals from affecting the accuracy of electrical continuity monitoring data, and ensure that the test results are true and reliable.

[0012] Preferably, the inner wall of the groove at the bottom of the modular adapter card seat is provided with a polytetrafluoroethylene lubricating layer, which is in contact with the outer wall of the connecting column to reduce component wear during vibration and extend the service life of the device.

This flexibility is ideal for occasions that require frequent vibration testing of different connectors. RF connectors with different outer diameters usually require different card holders for adaptation. By using modular adapter card holders, card holders can be flexibly replaced according to different RF connector outer diameters, thus ensuring wide compatibility of the equipment.

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a simple radio frequency cable assembly vibration testing device, including a mounting plate 1 and an adapter component. The top of the mounting plate 1 has a through hole 2, and the top of the through hole 2 is provided with a modular adapter bracket 3. The adapter component is disposed on the mounting plate 1 and the modular adapter bracket 3. The adapter component includes a movable plate 5, a spring 6, a slot 8, a T-shaped block 9, and a connecting post 10. The spring 6 is fixedly installed on one side of the movable plate 5. The bottom of the modular adapter bracket 3 has a sliding groove, and the connecting post 10 is slidably installed in the sliding groove. The bottom of the connecting post 10 is fixedly installed with a T-shaped block 9. A limit groove is provided on one side of the slot 8, and the protruding end of the T-shaped block 9 is engaged and installed in the limit groove.

[0018] Furthermore, the top of the modular adapter card holder 3 has interconnected through holes. RF connectors 4 are installed inside the through holes 2 and 3. The interconnected through hole design ensures precise installation of the RF connectors 4, enabling rapid docking with the cable assembly under test. As the core of electrical signal transmission, the RF connectors 4 provide a stable connection interface for subsequent electrical continuity monitoring. Their fitting installation with the modular adapter card holder 3 ensures that there is no loosening at the docking point during vibration, avoiding the impact of poor contact on the accuracy of test data.

[0019] Furthermore, the adapter component also includes a push rod 7. The modular adapter base 3 has two sets of rectangular slots arranged in a rectangular array. The movable plate 5 is slidably installed within the rectangular slots. The other end of the spring 6 is fixedly installed to one side of the rectangular slot. A damper is installed inside the spring 6. The push rod 7 is fixedly installed to one side of the movable plate 5, and the other end of the push rod 7 extends to the outside of the modular adapter base 3. Multiple slots 8 are located on the top of the mounting plate 1. The connecting post 10 is slidably engaged inside the slot 8. Manually pushing the push rod 7 outside the modular adapter base 3 causes the movable plate 5, which is fixed to it, to slide along the rectangular slots on the base. The spring 6 on one side of the movable plate 5 is compressed, thus... 9 is installed inside 8. When the push rod 7 is released, the spring 6 pushes the movable plate 5 to reset under the action of elastic restoring force. This causes the connecting post 10 on the movable plate 5 to drive the T-shaped locking block 9 to slide along the locking groove 8 on the top of the mounting plate 1 until the protruding end of the T-shaped locking block 9 is locked in the limiting groove of the locking groove 8. This allows the user to replace and adjust the locking plate as needed, thereby saving storage and operating space. This flexibility is very suitable for occasions that require frequent vibration tests of different connectors. RF connectors with different outer diameters usually require different locking plates to adapt to them. By using modular adapter locking plates, the locking plates can be flexibly replaced according to different RF connector outer diameters, thereby ensuring wide compatibility of the equipment.

[0020] Furthermore, the RF connector 4 end of the modular adapter card 3 is soldered with a wire 11, and a protective sleeve 12 is provided at the connection between the RF connector 4 and the wire 11. The other end of the wire 11 is connected to the vibration / shock equipment. The soldered connection between the wire 11 and the RF connector 4 ensures stable electrical signal transmission and meets the electrical continuity monitoring requirements of the national military standard. The protective sleeve 12 can cover the solder joint to prevent the solder joint from falling off or the wire from being damaged during vibration.

[0021] Furthermore, an insulating bushing is installed inside the through hole, which not only isolates electromagnetic interference but also buffers the impact force on the connector during vibration, extending the connector's service life.

[0022] Secondly, conductor 11 is a shielded conductor, and the shielding layer adopts a tin-plated copper wire braided structure, which can effectively isolate electromagnetic interference in the vibration test environment, avoid external interference signals from affecting the accuracy of electrical continuity monitoring data, and ensure the authenticity and reliability of test results.

[0023] Secondly, the inner wall of the slide groove at the bottom of the modular adapter card holder 3 is provided with a polytetrafluoroethylene lubricating layer. The lubricating layer is in contact with the outer wall of the connecting column 10, which reduces the wear of components during vibration and extends the service life of the device.

[0024] Working principle: According to the connector specifications of the RF cable assembly to be tested, the operator manually pushes the push rod 7 on the outside of the modular adapter card holder 3. The push rod 7 drives the movable plate 5 fixed thereto to slide along the rectangular groove on the card holder. The spring 6 on one side of the movable plate 5 is compressed, and 9 is snapped into the 8. The push rod 7 is released, and the spring 6 pushes the movable plate 5 back to its original position under the elastic restoring force. This causes the connecting post 10 on the movable plate 5 to drive the T-shaped card block 9 to slide along the card groove 8 on the top of the mounting plate 1 until the protruding end of the T-shaped card block 9 is snapped into the limiting groove of the card groove 8, realizing the lateral positioning of the adapter card holder and preventing displacement during vibration. Then, the RF connector 4 is screwed in. Inside the insulating bushing of the adapter card holder, the end of the RF connector 4 is soldered to the wire 11, and a protective sleeve 12 is fitted at the solder joint. The other end of the wire 11 is connected to the monitoring terminal of the vibration / shock equipment, forming an electrical continuity monitoring loop of the cable assembly, RF connector 4, wire 11, and monitoring terminal. This is to prepare for real-time monitoring of the continuity of the inner and outer conductors during the test. The vibration equipment outputs vibration or shock signals in the X, Y, and Z directions in accordance with the requirements of the national military standard GJB1215B-2021. The mounting plate 1 drives the modular adapter card holder 3, RF connector 4, and cable assembly to vibrate synchronously, simulating the actual working conditions of the cable assembly.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
