About some of the relevant content of the circular electric connector, everyone to understand

  Let’s take a look at some related content about circular electrical connectors:

  1. Precautions when storing circular electrical connectors

  When using circular electrical connectors, please use and store them correctly to avoid unnecessary trouble. When we receive the circular electrical connector, we should carefully observe whether the outer packaging is obviously damaged and whether the connector itself is damaged. We must ensure that the connectors we see are in good condition so as not to affect our use of circular electrical connectors. When the circular electrical connector is not in use temporarily, do not place the connector haphazardly, especially in a sunny place. If forgotten to be placed in the correct position, the connector will be damaged due to long-term exposure to sunlight, so we should carefully remember where the connector can be placed and never cause safety accidents due to carelessness.

  Circular electrical connectors should not be placed in high temperature places. Continuous high temperature or high humidity will damage the connector. Especially in an environment with chemicals, the circular electrical connector will be corroded, causing the outer metal protective layer to lose its protective function, leading to the destruction of the internal current loop. Without proper electrical conductivity, waste becomes valuable.

  Don't always panic when you need to move a connector. Be careful when using it to avoid damaging the service connector when the network connector hits a hard object, and do not place it under heavy development objects yourself to avoid crushing the connector. Another enemy of circular electrical connectors are greasy objects. If it comes into contact with greasy objects during storage or use, the electrical connector will lose its original effectiveness and become an obstacle to our work.

  2. How to connect the circular electrical connector to the application

  1. In the connector design process, the rated current is specified based on the thermal design of the electrical connector. As current flows through the contact pair, the contact pair may heat up due to the electrical conductor resistors and contact resistors.

  2. When its combustion exceeds a fixed limit, it will destroy the insulation layer of the circular electrical connector, causing the surface coating to contact soften and cause common failures.

  3. In order to limit the rated current, the actual temperature rise inside the connector should not exceed the standard value of the design plan.

  4. The issue that should be paid attention to when selecting is: for multi-core circular electrical connectors, the rated current must be derated.

  5. Pay more attention to this point in places with high current. For example, for Q 3.5mm contact pair, the rated current is generally required to be 50A, but when using 5 cores, the derating is 33%, that is, the rated current of each core wire is only 38A, the larger the cable model, the greater the derating.

  3. How to reduce joint wear of circular electrical connectors?

  When you plug in an electrical connector, you can only use a certain amount of force to open the prongs, but they're easier to pull out. Therefore, the insertion of an electrical connector is stronger than its removal. Wear in circular electrical connectors is therefore easily caused by the interaction of insertion and extraction forces. If you want to reduce wear and tear, try the following:

  1. It can improve the hardness of the gold-plated layer on the contact surface and effectively reduce friction.

  2. The contact surface of the circular electrical connector can be plated with nickel first and then gold, which has less friction than direct copper plating. The thicker the nickel layer, the higher and stronger the wear resistance of the gold plating layer.

  3. The smoother the surface, that is, the lower the roughness, the smaller the friction.

  4. During normal use of military circular electrical connectors, attention should be paid to the maintenance of the electrical connector to avoid artificial damage to the circular electrical connector.
