1: Use the wrong connector or a faulty connector
2.4 MM connectors cannot be mixed with 2.92 mm, and 3.5 mm, SMA connectors. Incorrect use of methods can cause permanent mechanical damage. A problem with problems needs to be discarded in time, otherwise, it will affect other devices connected to it. For example, the positive connector of the polarizer will damage the internal conductor connected to the negative connected negative connector.
2: Twist the connector with bare hands
When the connector is twisted with bare hands, it will bring poor test results. The figure below is a repetitive experiment of a real 1.85 mm connector S21 phase. Because there is no torque wrench, the phase result jumps at 30 GHz. The subsequent data table is compared in detail. The higher the measuring error -the higher the frequency, the greater the error.
3: Use the wrong torque wrench to twist the connector
The third big thunder area is twisting the connector with the wrong torque wrench. The reason for using a torque wrench is to ensure that the force applied to each connection is the same, that is, each time is the same so that the repeated measurement results can be obtained, and it is guaranteed not to damage the connector due to excessive force. Therefore, due to the different dimensions, materials, and attributes, different connectors need to use different torque wages. The following table is for your reference.
4: Incorrect use of a torque wrench to twist the connector
Sometimes, the torque wrench is right, but it still causes damage to the connector. Why is this again? It's simple, your method is wrong. Yes, the method is very important, such as the position, angle, and so on. In so many connectors we just said, the 1.0 mm connector is particularly fragile, so we need to strictly follow the operation steps when connecting.
5: Put the connector together for storage management
At the scene of some users, we found that everyone put all the connectors in a box. The advantage of this is convenient access. However, the problem is that every time you look for a connector, you need to find it in the box. The connector will collide, which will easily cause mechanical wear. Due to the changes in size, Damage to the device. Therefore, we recommend that the connector is separated separately. If you must concentrate together, you can find a piece of anti-static material, dig some grooves according to the size of the connector, and put the connector separately. This is clear at a glance, easy to access, and it can also protect the connector from damaged.
The above are the points that should be avoided when using, so in the future, everyone should try to avoid it as much as possible in the future to avoid affecting the performance and life of the connector.
