Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a plug compression testing device. Background Technology

[0002] The core purpose of plug compression testing is to verify the mechanical strength and safety of plugs under complex working conditions. Plugs may be subjected to squeezing, impact, or prolonged pressure (such as being crushed by heavy objects) during transportation, installation, or daily use. If the outer shell cracks, the metal contacts deform, or the insulation fails, it may cause safety hazards such as electric shock, short circuit, or fire. According to international standards (such as IEC60884-1) and domestic standards (such as GB / T2099.1-2021), the test requires applying 300N of pressure and maintaining it for 1 minute to simulate the compressive strength under extreme scenarios, ensuring that the plug does not suffer functional damage or dimensional deviations after being subjected to pressure. In addition, this test can also evaluate material properties (such as the resistance of plastics to brittleness and the bending resistance of metal terminals) and the rationality of structural design, providing a basis for product optimization.

[0003] Traditional plug compression testing devices generally suffer from the drawback of a single compression direction. In practical applications, plugs may be subjected to dynamic loads at multiple angles, such as tilting forces during drops or compound compression in confined spaces. Existing adjustment schemes, such as manual rotation of clamps or toothed meshing structures, require manual intervention and are prone to angular deviation due to operational errors. Therefore, we propose a plug compression testing device. Utility Model Content

[0023] The working principle of the plug compression testing device provided by this utility model is as follows: The plug to be tested is placed between the two movable frames 41 of the clamping assembly 4. The first motor 43 is started to drive the bidirectional screw 42 to rotate, so that the two movable frames 41 slide towards each other along the strip opening of the mounting plate 1 and clamp the plug through the rubber disc 53. When it is necessary to adjust the compression angle of the plug, the third hydraulic rod 62 of the fixing assembly 6 retracts, driving the clamp 63 to disengage from the slot 64 of the turntable 52. Then, the second motor 51 of the rotating assembly 5 drives the right turntable 52 to rotate, driving the left turntable 52 to rotate synchronously, so that the plug is adjusted to the target angle around the axis. After the compression test, the third hydraulic rod 62 pushes the clamp head 63 to re-clamp into the corresponding slot 64 to lock the turntable 52. At this time, the first hydraulic rod 22 of the extrusion assembly 2 pushes the connecting plate 24 to move upward, so that the pressure sensor 25 and the extrusion head 33 of the support assembly 3 respectively abut against the upper and lower surfaces of the plug. The first hydraulic rod 22 drives the connecting plate 24 to apply load. The pressure sensor 25 monitors the pressure data in real time and feeds it back to the PLC controller. The output of the hydraulic rod is dynamically adjusted through closed-loop control to complete the compression test. This process achieves angle adaptive adjustment, precise pressure application and real-time monitoring through multi-component collaboration, ensuring that the test is efficient and reliable.

[0024] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The first hydraulic rod 22, the second hydraulic rod 32, the third hydraulic rod 62, the first motor 43, the second motor 43, and the pressure sensor 24 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of the first hydraulic rod 22, the second hydraulic rod 32, the third hydraulic rod 62, the first motor 43, and the second motor 43 using methods commonly used in the prior art.
