Description

Technical Field

[0001] This utility model belongs to the field of pressure resistance testing technology, and specifically relates to a pressure resistance testing device for motherboard extruded parts. Background Technology

[0002] During the production of busbars, an insulation layer needs to be applied to the middle part of the busbar. This is usually done by extrusion coating or thermoplastic tubing to improve the various properties of the busbar, such as fire resistance, insulation, and pressure resistance.

[0003] After the extruded parts are applied to the busbars, they need to undergo a pressure resistance test. Existing testing equipment is time-consuming and labor-intensive to install and remove the busbars, requiring manual opening and closing of the testing device. For testing busbars with longer lengths, the pressure cap is heavy, increasing the labor intensity for workers. On the other hand, due to the repetitive nature of the same actions over a long period, workers are prone to mixing defective products with qualified products, affecting the quality of a batch of products.
