[0002] With the rapid development of electronic technology, electronic loads have been widely used in power supply testing, battery testing, electronic equipment aging testing and other fields. Electronic loads simulate the electrical characteristics of actual loads to evaluate the performance of the power supply or battery under test. In practical applications, electronic loads often face complex and changeable working environments, especially outdoors or in industrial sites. Waterproofing and shockproofing have become key factors affecting the performance and service life of electronic loads.

[0003] During operation, electronic loads are prone to vibration due to the vibration of internal electronic components and mechanical shock from the external environment. Long-term high-frequency vibration will not only affect the measurement accuracy and stability of the electronic load, but may also cause the internal structure to loosen and be damaged, shortening the service life of the electronic load. The waterproof and shockproof structure of existing electronic load devices is usually difficult to disassemble and assemble quickly, and it is difficult to improve the shock protection of the device, which needs further improvement.
