What waterproof connector inspectors need to do?

When checking the appearance, electrical performance, etc. of the electrical connector and its parts, the electrical connectors and their parts are usually disassembled. After checking the relevant items, they must be reassembled. To avoid accidents such as personal injury and accidental loss of parts.

Personnel engaged in the inspection of electrical connectors and their components (wiring harnesses) must do the following;

1) The inspector must be familiar with the design structure and assembly and disassembly procedures of the electrical connector under inspection. The operator should contact the relevant manufacturer or disassemble it according to the requirements of the product instruction manual. The tools used in the inspection The electrical connector should be in good condition Non-destructive, the performance should be qualified; the probe should meet the standard requirements, otherwise the jack will be easily damaged.

2) When removing the connector tail attachment of the electrical connector assembly, do not rotate the connecting nut on the tail attachment before loosening the cable clamp, otherwise the electrical connector, termination point or wire core may be damaged.

3) When disassembling the electrical connector, the operator should fully understand the disassembly conditions and methods of the electrical connector, and disassemble and assemble according to the requirements of the product instruction manual. Special attention should be paid to whether there are missing or incorrectly assembled parts, and whether the assembly is correct, Contact serial numbers are correct and rubber parts are not kinked. Assembled connectors should be tested for connection to ensure interchangeability.

Actually, let’s talk about the waterproof rating characteristics of waterproof connectors. I believe everyone is familiar with it. Many friends may think this is a very simple question. In fact, it is not the case. When choosing a waterproof connector, you must consider In the specific application environment, if the connector we choose cannot meet the actual waterproof requirements, it will lead to failure. Today, let us make a simple example for you from the difference between the waterproof performance of waterproof connectors IP7 and IP8. Hope Help everyone.

So, under what circumstances do we usually use IP67 waterproof connectors? Usually, with such a connector, we can use it to prevent water from entering during short-term immersion.

Of course, if continuous waterproof protection is required, IP67 waterproof connectors cannot meet our needs. For continuous immersion under certain pressure, which can prevent water from entering during the complete continuous immersion process, we can choose IP68 waterproof connectors.
