What Should I Pay Attention To When Choosing Waterproof Connectors
When using Nylon Cable Gland in normal times, you should pay attention to the following points:
1. Current carrying capacity: When you choose a connector with a power signal, you will pay more attention to the current carrying capacity of the connector. You should use a simplified design and pay attention to the insulation and withstand voltage between the pins.
2. Structural design dimensions: The dimensions of the waterproof connector are very important. The connections in the product (especially single-board connectors) have certain spatial environmental restrictions and cannot interfere with other components. According to the students' use of cyberspace and the installation location (system installation through front and back installation, installation and fixing teaching methods mainly include rivets, screws, collars or quick lock connectors themselves, etc.), select the appropriate installation management method and choose different shapes (straight, curved, T-shaped, round, square).
3. Impedance matching: Some signals have impedance requirements, especially radio frequency signals, which have stricter impedance matching requirements. When the impedance is not matched, the signal will be reflected, which will affect the transmission of the signal. Ordinary signal transmission has no special requirements for connection impedance.
4. Shielding: With the development of communication products, EMC is increasingly valued. The selected waterproof connector requires a metal shell and the cable needs to have a shielding layer. The shielding layer should be connected to the metal shell of the connector to achieve the shielding effect. The plug can also be partially wrapped on the copper skin through injection molding, and the shielding layer of the cable can be welded on the copper skin.
5. Anti-misinsertion: There are two aspects to prevent misinsertion: On the one hand, the connector itself, the connector itself rotates 180 degrees, and the wrong connection leads to the wrong signal connection. On the other hand, in order to reduce the diversity of data, multiple signals use the same waterproof connector, and it seems that plug a is inserted into plug b. It should be noted that if the situation is serious, different types of sockets must be selected for interfaces a and b.
6. Multi-purpose: In the process of selecting waterproof connectors, common items should be selected as much as possible, especially between products in the same series. The choice of waterproof connectors is very universal, which can reduce the types of materials, increase the quantity, reduce costs, and reduce supply risks.
