How to protect the pogo pin connector?

What kind of damage does the connector generally appear and how to protect it?
In our daily life, we will inevitably encounter damage to the electrical connector, which will cause unnecessary trouble. Therefore, we protect it during use, so what factors are causing the damage to the connector; today, the editor will come to Explain to everyone:

(1) The electric connection wire or wire clamp does not have enough current to be burned or broken.
(2) The electrical connection wire is severely broken, and the strand or wire is burned.
(3) The electrical connection wire is corroded seriously, causing the cross-sectional flow surface to be insufficient and the strand or wire is burned.
(4) Poor contact between the electrical connection line and the wire clamp or poor contact between the power supply line clamp and the contact wire, causing burns.
(5) The current-carrying surface of the wire clamp and the lead is not contacted enough, causing burning.
(6) The loosening of the wire clamp nut was not found and treated in time, causing the electrical connector to fall off.
(7) There is no temperature change after the connector is installed, the offset is reserved or the offset reserved is too small.
(8) After the connector is installed, the reserved value of the temperature change offset is large, and the vertical electrical connection line between the load-bearing cable and the contact line relaxes until it relaxes to the lower part of the contact line and is damaged by the pantograph in operation. Or cut off. The distance between the bottom ring of the vertical part and the contact line is too small, and it is damaged by the pantograph.
(9) The installation of the power supply clamp on the contact wire was skewed and was knocked out by the pantograph, which caused a bow slashing accident.
(10) A bow was cut at other positions on the catenary, and the pantograph continued to run to the place where the connector was installed and the electrical connector was broken.
