Description

Technical Field

[0001] The utility model relates to the technical field of plug testing, in particular to a swing testing device for testing the curvature of a plug. Background Art

[0002] Plugs are important tools for connecting electrical equipment to a power source. Qualified plugs should have good reliability and durability to avoid breakage, short circuits, etc. due to poor quality of metal lead materials or workmanship problems.

[0003] After the plug is assembled, it needs to be tested for curvature. The metal wires inside the electrical plug, the leather cover on the outer wall of the metal wires, and the connection ends should be inspected to avoid breakage, short circuit, etc. caused by poor plug quality or process problems. Weights need to be added to the plug connection line during the inspection. When the plug is swung during the curvature test, the added weights can simulate tensile resistance. The weights need to be manually bound to the connection line, and the clamping process is inconvenient. Different plug specifications require different pulling forces, and the weights need to be adjusted. For this reason, we propose a swing test device for plug curvature test to solve the existing problems. Utility Model Content
