Remove electrical connectors and components when checking their appearance and electrical performance. After checking the related items, they must be reassembled. To avoid personal injury and accidental loss of parts and other accidents.
Personnel engaged in checking electrical connectors and their components (wiring harnesses) must perform the following operations;
1) The inspector must be familiar with the design structure and assembly and disassembly procedures of the electrical connectors being inspected. The operator shall contact the relevant manufacturer according to the requirements of the product description manual or disassemble it. The electrical connectors used in the inspection should be intact and have acceptable performance. Probe should meet the standard requirements, otherwise the jack is easy to damage.
2) When removing the connector tail accessories of the electrical connector assembly, do not rotate the connection nut on the tail accessories before releasing the cable clip. Otherwise, the electrical connector, end contact, or wire core may be damaged.
3) When disassembling electrical connectors, operators should fully understand the disassembling conditions and methods of electrical connectors and disassemble them according to the requirements of the product instruction manual. Special attention should be paid to missing or misassembled parts, correct assembly, correct contact serial number and kink of rubber parts. Assembled connectors shall be tested for connection to ensure interchangeability.
Actually, let’s talk about the waterproof rating characteristics of waterproof connectors. I’m sure everyone is familiar with it. Many friends may think this is a very simple question. In fact, this is not the case. When choosing a waterproof connector, you must consider the specific application environment. If the connector cannot meet the actual waterproof requirements, it may cause a failure. Today, let’s make a simple example for you from the difference between waterproof connector IP7 and IP8′s waterproof performance. Hope to help you.
So, when do we usually use IP67 waterproof connectors? Usually, with a connector like this, we can use it to prevent water from entering during a short immersion.
Of course, if continuous waterproof protection is required, the IP67 waterproof connector will not meet our needs. In order to continuously immerse under certain pressure, which can prevent water from entering in the complete continuous immersion process, we can choose IP68 waterproof connector.
