Air leakage detection device used for automobile connector

Abstract

The invention relates to an air leakage detection device used for an automobile connector. The device includes a connector holding mechanism, a water storage box, an air pressure cavity and an air pressure valve. The air pressure valve is mounted on an air pressure cavity. The air pressure cavity communicates with the water storage box. After the connector holding mechanism clamps the to-be-testedautomobile connector, the automobile connector is placed in water of the water storage box and the air pressure valve is opened at the same time. If the water in the water storage box bubbles, abnormity of the automobile connector is proved. Compared with the prior art, the device provided by the invention has advantages of high detection precision, operation convenient and good practicability and the like.

Description

technical field [0001] The invention relates to a detection device for an automobile connector, in particular to an air leakage detection device for an automobile connector. Background technique [0002] At present, some products are required to be airtight, and now it is all based on measuring the size and looking at the appearance. It is difficult to judge whether there is an abnormal air leakage, and there is a great risk. [0003] One of the currently disclosed methods for connector air leakage detection is to detect whether the pressure in the connector changes within a period of time. The biggest defect of this method is that the detection process takes a long time and takes a lot of time; another method The connector is injected with gas and immersed in water to observe whether there are bubbles. Although this method can achieve the purpose of detection, it is very inconvenient and time-consuming to immerse the connector in water. These two methods are not suitable f...

[0003] One of the currently disclosed methods for connector air leakage detection is to detect whether the pressure in the connector changes within a period of time. The biggest defect of this method is that the detection process takes a long time and takes a lot of time; another method It is to inject the connector into the water after injecting gas, and observe whether there are bubbles. Although this method can achieve the purpose of detection, it is very inconvenient and time-consuming to immerse the connector in water.

Both of these methods are not suitable for mass production of automotive connectors
