Testing tool for immersion test chamber

Abstract

The invention discloses a testing tool for an immersion test chamber. The testing tool comprises a horizontal pressing plate, a plurality of threaded columns, a plurality of sets of fastening nuts, and a fixing support fixed to the bottoms of the threaded columns, wherein the horizontal pressing plate is provided with a plurality of pressure through holes running through upper and lower boards, and a plurality of threaded column through holes are formed in the periphery of the horizontal pressing plate; the threaded columns are matched with the threaded column through holes, and the upper endsof the threaded columns run through the threaded column through holes; the fastening nuts are in fit with and in screw connection with the threaded columns, each set of fastening nuts include an upper nut and a lower nut which are distributed at the upper and lower surfaces of the horizontal pressing plate; the testing tool can fix irregular testing samples with buoyancy to the maximum extent, identical or different samples can be measured at the same time to a large extent while the testing efficiency is improved.

Description

technical field [0001] The invention relates to the field of water immersion test, in particular to a test tool for a water immersion test box. Background technique [0002] With the widespread use of electronic equipment, various electronic products are used in many fields, and their working environments vary widely. Working environments such as extreme cold, high temperature, and deep water are not uncommon. Therefore, higher requirements are put forward for the quality of electronic equipment. Product quality Defects will have a great impact on the production and life safety of manufacturers, industry users, and end customers. In order to improve product quality and ensure the stable operation of electronic products, relevant reliability experiments are usually designed to verify product reliability in the development stage of electronic products. According to the current relatively mature electronic product environmental experiments, some problems were found during the i...

Problems solved by technology

However, from the actual test results, there are many shortcomings in the existing fixing methods. 1) When the sample volume is large, and the buoyancy is far greater than the gravity, a lot of counterweights are needed, which takes up a lot of space in the box and slows down the test progress. ; 2) In order to ensure the progress of the experiment, it is often necessary to test multiple samples of the same and different physical structures at the same time during the experiment. If the test sample does not have a physical through hole, the series line will not be able to connect the samples in series, and the sample can only be connected with a series line. Bundle, but this will cause obvious local force on the sample, and there is a risk of damage to the shell, and for spherical samples, it cannot be bundled with series wires. The traditional countermeasure is to place the sample in a net bag, and then drop the weight. This method is conducive to sample fixation, but the number of counterweights required is uncertain, and it takes up a lot of underwater space, which is not conducive to the implementation of the experiment
