Abstract

The invention provides an anti-shock and anti-compression testing device for an electronic component, and belongs to the field of electrical component detection. Comprising a vibration base, a wind pressure assembly and a carrying assembly, the carrying assembly is arranged on the vibration base, the wind pressure assembly is arranged on the carrying assembly, the wind pressure assembly and a sundry assembly are eccentrically arranged, the vibration base comprises a base pipe and an outer bearing ring, the outer bearing ring is arranged on the base pipe, the base pipe is a corrugated pipe, and a fixing flange is arranged at the bottom of the base pipe. The outer bearing ring is arranged on the upper portion of the base pipe in a sleeved mode and extends outwards, an annular groove is formed between the outer bearing ring and the base pipe, a plurality of communicating holes are formed in the outer side wall of the outer bearing ring, connectors are arranged in the communicating holes, and the lower sealing ring is arranged on the base pipe in a sleeved mode and connected with a draught fan through an air pipe to form air pressure injection. Impact detection is carried out on the electrical components in the transparent protective cover in cooperation with slag inclusion particles in the injected airflow, a pressure test is formed, the humidity in the airflow is adjusted, and permeation resistance detection is carried out on electrical component packaging.

Description

technical field [0001] The invention provides an anti-seismic and pressure-resistant testing device for electronic components, which belongs to the field of electrical component detection. Background technique [0002] At present, electronic components are one of the main components of control systems such as equipment and instruments. Due to the tight overall structure and modular connection combination, the connection points are mainly plug-in and welding structures. During the working process, due to different working conditions , the electronic components need to form the anti-seismic and compressive requirements, and the existing ones are fixed by the external protective cover to form the anti-seismic and compressive force, but the limit of the overall protection strength cannot be known, and due to the complicated working conditions, simple protective covers cannot be adapted Vibration and pressure shocks under various environmental factors require an overall test.

[0002] At present, electronic components are one of the main components of control systems such as equipment and instruments. Due to the tight overall structure and modular connection combination, the connection points are mainly plug-in and welding structures. During the working process, due to different working conditions , the electronic components need to form the anti-seismic and compressive requirements, and the existing ones are fixed by the external protective cover to form the anti-seismic and compressive force, but the limit of the overall protection strength cannot be known, and due to the complicated working conditions, simple protective covers cannot be adapted Vibration and pressure impact under various environmental factors require an overall test. The existing test structure lacks the structure for anti-seismic and compressive testing of electronic components, especially the anti-compressive setting for weather resistance
