How to choose the right Huawei FastConnect

1. Carrying capacity

When choosing the connector for the power signal, pay more attention to the current carrying capacity of the Huawei FastConnect, adopt a derating design, and pay attention to the insulation withstand voltage between the pins.

2. Structural size

The external dimension of Huawei FastConnect is very important. There are certain space restrictions for connections in the product, especially the single-board connector, which cannot interfere with other components. Choose the appropriate installation method according to the use space and installation position (installation includes front installation and rear installation, installation and fixing methods include rivets, screws, collars or quick locking of the connector itself, etc.) and shape (straight, curved, T type, round, square);

3. Impedance matching

Some signals have impedance requirements, especially RF signals, which have stricter impedance matching requirements. When the impedance does not match, it will cause signal reflection, which will affect signal transmission. There is no special requirement for the impedance of Huawei FastConnect in general signal transmission.

4 shield

With the development of communication products, more and more attention is paid to EMC. When choosing Huawei FastConnect, a metal casing is required, and the cable needs to have a shielding layer. The shielding layer must be connected with the metal casing of the connector to achieve the shielding effect. Using the injection molding method, the plug part is wrapped with copper skin, and the shielding layer of the cable is welded with the copper skin.

5. Anti-misinsertion

There are two aspects to prevent mis-insertion: on the one hand, Huawei FastConnect itself, the connector itself rotates 180 degrees, and the wrong connection leads to wrong connection of signals. Make the assembly unique; on the other hand, in order to reduce the variety of materials, the same connector is used for several signals. At this time, it may occur that the A plug is inserted into the B socket. At this time, you need to pay attention. If this happens When serious consequences (not simple alarms, destructive) are caused, the A and B interfaces must be selected as different types of sockets (for example, A is male, B is female);

6. Reliability

Huawei FastConnect is used to connect the signal, so the connection part must be reliable.

7. Versatility

In the selection process of Huawei FastConnect, it is necessary to choose common materials as much as possible, especially among products of the same series, the selection of connectors has strong versatility, reducing the types of materials, increasing the quantity, reducing costs, and reducing supply risks.

In the process of choosing Huawei FastConnect, various factors are not independent and often interact with each other. Therefore, we must comprehensively consider in the process of connector selection and choose the most suitable connector. The quality of the selection will vary at different stages. degree of impact on the product.
