What are some of the common failures encountered when using circular connectors?

I. What are the frequently encountered failures when using circular connectors? Generally speaking, the common failures of circular connectors can be divided into four categories, namely, poor sealing, poor insulation, poor contact and poor fixation, which are analyzed and introduced below: 1. Poor contact. (1). Phenomenon: contact resistance becomes large. Reason: the plug of the circular connector is loose, the positive pressure is reduced or the elastic piece is deformed. Exclusion: Replace the new contact parts. (2). Phenomenon: Poor contact of contact piece, resulting in disconnection. CAUSE: Incorrect use of the jack can cause the diameter of the jack to change. Method: Replace with a new jack. (3). Phenomenon: The curtain of the contact piece moves. Cause: Excessive error in the size of the contact piece or damage to the jaws. Remedy: Directly replace the circular connector or replace the contact piece. (4). Phenomenon: Damaged or broken wires, resulting in disconnection. Cause: Uneven force on the wires when the harness is wound, poor soldering of the connection ports, wrong installation. Remedy: Use the correct installation method and re-solder the contact pieces.2. Poor insulation. (1). Phenomenon: short circuit, insulation resistance is super poor. Cause: moisture or impurities in the use of the environment. Elimination: choose a dry and clean environment, clean up the impurities. (2). Phenomenon: insulator breakage. Reason: too much force when plugging and unplugging, defective insulator.

Remedy: Replace with a new circular connector or insulator.

3. Poor fixation. (1). Phenomenon: shell damage. Cause: internal defects or external damage during processing. Remedy: Re-exchange the qualified replacement connector. (2). Phenomenon: Plug and socket cannot be inserted. Reason: plug and socket mismatch. Exclusion: If you can't plug it in, you can't force it in. Before inserting it, check the alignment of the jack position.4. Poor sealing. Phenomenon: sealing performance is impaired. Reason: aging and failure of seals. Method: Replace with new seals.
