Water tightness test device for electronic equipment case

Abstract

The invention discloses a water tightness test device for an electronic equipment case, and belongs to the technical field of water tightness test of electronic equipment. The device comprises a watertank and a lifting structure. The lifting structure comprises a lifting rod extending into the water tank, a driving motor arranged on the water tank and used for driving the lifting rod to move, anda platform arranged at the bottom end of the lifting rod and used for placing a to-be-tested case. The platform is further connected with a plurality of sets of hanging assemblies used for keeping the levelness of the platform. Each set of hanging assembly comprises a horizontal motor arranged above the platform, a first pulley arranged on the bottom face of the water tank and a second pulley arranged on the upper edge of the water tank. An output head of each horizontal motor is wound with a balance line, and the balance lines sequentially pass through the first pulleys and the second pulleys and are finally connected to hooks arranged on the upper surface of the clamping platform. The electronic equipment watertight case test technology is mainly improved, the water tightness test device can adapt to cases of different forms, the test depth of a case can be accurately adjusted, and control over test variables is clearer.

Description

technical field [0001] The invention belongs to the technical field of water-tightness testing of electronic equipment, in particular to a water-tightness testing device for electronic equipment casings. Background technique [0002] With the rapid development of the current communication industry, electronic equipment chassis are widely used in military and civilian applications. Since most of the components in the equipment are electronic components, the working environment is often harsh, which requires the chassis to have certain waterproof performance. , in the design process of the chassis, its watertight performance is its main index. [0003] At present, the methods of chassis water test are mainly divided into three methods: dripping, flushing and immersion. According to the different protection requirements of the equipment, related tests are carried out, and the methods used are also different. The dripping test is mainly carried out in the open rain.

Problems solved by technology

[0003] At present, the methods of chassis water test are mainly divided into three methods: dripping, flushing and immersion. According to the different protection requirements of the equipment, related tests are carried out, and the methods used are also different. The dripping test is mainly carried out in the open rain. It is greatly affected by the weather. The flushing test is mainly carried out by using a shower, which needs to be manually held to meet different angles. The method needs to be carried out manually. To a certain depth of water, soak for a corresponding time, but when the chassis is immersed in the water tank, it is usually to add a certain amount of heavy objects to the chassis to make the chassis sink to a certain depth, but the internal weight of the chassis is often unevenly distributed, and the chassis sinks After that, there may be a certain degree of overturning, and the chassis may not be placed stably.

[0004] Based on the above analysis, it can be found that there are some deficiencies in the existing watertightness testing methods: the current watertightness testing methods do not have a unified device that can satisfy the above-mentioned related tests at the same time, and the test methods are greatly affected by artificial and weather factors. , the test is relatively cumbersome, and the labor cost of the test itself will be high
