Description

Technical Field

[0001] This utility model relates to the field of battery connector testing technology, and in particular to a pressure resistance testing device for battery connectors. Background Technology

[0002] The background technology of battery connector withstand voltage testing mainly involves the safety and reliability assessment of batteries. In a battery system, connectors play a crucial role in connecting individual battery cells or modules, and their quality and performance directly affect the stability and safety of the entire battery system. To ensure that battery connectors can function normally under high-voltage conditions without breakdown or short circuits, withstand voltage testing has become a critical testing method.

[0003] Withstand voltage testing typically involves applying a certain voltage to the battery connector and monitoring whether its leakage current remains within a safe range to determine the connector's insulation performance and breakdown resistance. This test helps to identify potential defects in the connector during production or use, such as material flaws, poor workmanship, or aging.

[0004] Existing testing methods typically use conductive materials (such as copper foil, aluminum foil, etc.) and require manual wrapping of the conductive material around the outside of the heat shrink tubing, with the wrapped portion overlapping by more than 1 / 2. During the test, one end of the test cable of the testing equipment is clamped to the metal part of one end of the product, and the other end is clamped to the copper foil. Power is applied to achieve the withstand voltage test of the battery connector.

[0005] However, existing testing methods use conductive materials such as copper foil and aluminum foil, resulting in high material costs. In addition, the conductive material needs to be manually wrapped around the battery connector, which is tedious and inefficient, and gaps may exist between the wrapped conductive materials, causing test errors.

[0006] Currently, no effective solutions have been proposed for the problems of high detection costs, low detection efficiency, and easy errors in related technologies. Utility Model Content
