Why is the RF connector signal unstable?

When using the connector, the pin should be opened with absolute force, but it is easier when it is separated. Therefore, it is judged that the connection of the electrical connector is more important than the separation force. Therefore, the interaction of the two forces of insertion and removal can easily cause the connector to wear out. If you want to reduce wear and tear, you can look at the following good methods: You can increase the strength of the gold plating layer on the contact surface of the connector, so that you can effectively reduce friction. The contact surface of the connector can be nickel-plated first and then gold-plated, which will cause less friction than gold plating directly on copper, which can reduce the wear of the connector.

The connection of the RF connector is not stable. As soon as it is used, the signal will be interrupted as soon as it shakes. It is required that our connector design should have a stable connection. It can be seen that the reliability of the performance of the RF connector consists of multiple factors.

1. The thicker the nickel layer, the stronger the wear resistance of the gold-plated layer.

2. The smoother the surface, that is, the lower the roughness, the less the friction.

3. On the way we usually ship the connector, we can reduce the behavior of artificial damage to the connector, and we must always pay attention to the maintenance of the connector.

As a FAKRA Long Female Connector Factory, briefly introduce the working frequency and frequency of RF connectors. The power capacity of the RF connector is an important performance index. The power transmission at DC or low frequency is completely different, and there are many factors that can affect it.

1. Pinhole size: The pinhole size is related to the current capacity of the connector and directly related to the power.

2. Voltage standing wave ratio: The reflected wave occupies the channel capacity space, which reduces the transmission power capacity.

3. Access loss: There is a difference between input and output power due to the loss.

4. Air pressure (altitude): Changes in air pressure cause changes in the dielectric constant of the air section, and the air is easily ionized to generate corona at low pressure. The higher the altitude, the lower the air pressure and the smaller the power capacity.

5. Contact resistance: The presence of contact resistance will cause contact heating, making it difficult to transmit microwave signals of greater power.

6. The influence of frequency: The change of the transmission signal frequency directly causes the loss and the voltage standing wave ratio to change, thus affecting the transmission power capacity.
