Description

Technical Field

[0001] This utility model relates to a charging head testing device, specifically a new energy vehicle charging connector testing device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, new energy vehicle charging equipment, as an important component, has received widespread attention and application. As a key interface connecting the vehicle and the power source, the stability and reliability of the new energy vehicle charging connector directly affect the charging efficiency and safety of the entire vehicle. Therefore, efficient and accurate testing of new energy vehicle charging connectors is particularly important.

[0003] Currently, various testing devices for new energy vehicle charging connectors are available on the market. These devices primarily function to test the mechanical strength, contact stability, and durability of the charging head's wires. However, existing technologies still have the following shortcomings in practical applications:

[0004] Most existing testing equipment relies on manual operation for clamping the charging head and applying torque, resulting in a cumbersome and inefficient testing process. Furthermore, manual operation makes it difficult to guarantee the consistency and repeatability of the tests, increasing the possibility of testing errors.

[0005] Existing devices often lack precise control mechanisms when applying torque, resulting in uneven torque application or insufficient force. This not only affects the accuracy of test results but may also cause unnecessary damage to the charging head during the test.

[0006] During testing, the charging head needs to be securely clamped to prevent displacement or loosening. However, the clamping mechanisms of existing testing devices are often simply designed and cannot adapt to different models and specifications of charging heads, resulting in insecure clamping or inconvenient operation, which affects the reliability of the test.
