Description

Technical Field

[0001] The utility model relates to the technical field of gas detector mainboard processing and detection, in particular to a gas detector mainboard slot testing jig. Background Art

[0002] Testing the gas detector motherboard slot is a key step in ensuring the normal operation and safety of the equipment. Through testing, it can be confirmed whether the slot can correctly receive and connect to the detector's sensor motherboard, ensure the connectivity of the circuit, and ensure that the detector can accurately read the gas concentration in the environment. It helps to find out whether the slot has physical damage, corrosion, poor contact or other problems that may cause functional failure. The test can evaluate the mechanical and electrical properties of the slot to ensure that they meet the design specifications and long-term stable operation requirements.

[0003] Moreover, in situations involving gas detection, equipment failure may lead to safety accidents. Ensuring the reliability of the motherboard slot through testing is an important measure to ensure personnel safety and normal operation of equipment. During the production process, testing the motherboard slot is a part of quality control to ensure that each detector leaving the factory meets the predetermined quality standards.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0005] Although the existing technology has solved certain problems, it still has the following disadvantages:

[0006] (1) The detection fixture used in the prior art drives the support plate with the plug-in module to move by the extension and contraction of the push rod or the connecting rod, so that the plug-in module is inserted into the slot of the main board. The main board is stationary during the insertion process. During the process of inserting the plug-in module into the slot of the main board, the main board is subjected to a large amount of rigid extrusion force and is easily damaged.

[0007] (2) The detection fixtures used in the prior art mostly clamp the motherboard on the base and allow the support plate with the plug-in module to move. If clamped, the clamping mechanism needs to be continuously controlled to replace the motherboard. Otherwise, it needs to be manually separated and then replaced. It is troublesome to unplug and replace the plugged-in motherboard. Utility Model Content
