How to Dismantle A Power Cable to Check the Quality?

When checking the appearance and water resistance of a waterproof connector and its components, the waterproof connector and its components being inspected are usually disassembled. After the relevant items have been checked, they need to be reassembled. This is to avoid accidents such as human damage and missing parts.

Notes on inspection

Inspectors working on waterproof connectors and their components (wiring harnesses) must do the following. GRAND ELECTRONIC shares with you.

1) The inspector must be familiar with the design structure and the assembly and disassembly procedures of the waterproof connector being inspected. The operator should contact the relevant manufacturer or follow the requirements of the product manual for disassembly and assembly. The waterproof connector used for inspection should be intact and its performance should be qualified; the probe should meet the standard requirements, otherwise it will easily cause damage to the jack.

2) When disassembling a connector tail attachment that has been made into a waterproof connector assembly, do not twist the coupling nut on the tail attachment before loosening the cable clamp, as this may damage the waterproof connector, junction or wire core.

3) If it is necessary to dismantle the waterproof connector, the operator should be fully aware of the conditions and methods of dismantling the waterproof connector and dismantle the waterproof connector in accordance with the product instructions. Particular attention should be paid to whether there are any missing or incorrect parts, whether the assembly is in place, whether the serial numbers of the contacts are correct and whether the rubber parts are twisted. The assembled connectors should be tested to ensure interchangeability.

IP7 and IP8

When we choose a waterproof connector, we must consider the specific situation. In the application environment, if we choose a connector that does not meet the actual waterproofing requirements, it will cause a failure.

 Under what circumstances are IP7 waterproof connectors used? Generally speaking, with such connectors we can use them to prevent water from entering during short periods of immersion.

If continuous waterproof protection is required, IP7 waterproof connectors will no longer meet our needs. For continuous immersion under a certain pressure, where water can be prevented from entering during a completely continuous immersion, we can choose IP8 waterproof connectors.
