The use of circular connectors commonly encountered faults and troubleshooting methods

In order to allow users to better use the circular connector, to prevent its use in the process of failure and when the failure can be found in a timely manner after the emergence of the appropriate elimination method, today Huicheng Yuan connector factory for the user to summarize the use of a commonly encountered faults and elimination methods.
Generally speaking, the more common circular connector failure can be divided into four categories, namely, poor sealing, poor insulation, poor contact and poor fixation. The following one by one analysis:
First, poor contact.
1, phenomenon: contact resistance becomes large
Causes: Circular connector jack has been slack, positive pressure becomes small or deformation of the elastic parts
Elimination method: replace the new contact parts
2、Phenomenon: the contact does not have good contact leading to disconnection
Reason: in use, the use of incorrectly lead to changes in the diameter of the jacks
Remedy: Replace the new jack
3、Phenomenon: Contacts curtain movement
Reason: the contact size error is too large or damage to the claw
Elimination method: directly replace the circular connector or can also replace the contact piece
4、Phenomenon: wire damage, breakage caused by circuit breakage
Reason: when wrapping the harness, the wire is not uniform force, the wiring port is not welded firmly, installation errors
Remedy: use the correct installation method, contact parts re-welding
Second, poor insulation.
1、Phenomenon: short circuit, insulation resistance is too poor
Cause: the environment used in the moisture or impurities
Elimination method: choose a dry, clean environment, clean up the impurities
2、Phenomenon: insulator broken
Reason: too much force when plugging and unplugging, defective insulator
Elimination method: replace the new circular connector or insulator
Third, poor fixation.
1, phenomenon: shell damage
Causes: processing internal defects or damage by external forces
Remedy: replace the qualified replacement connector
2, phenomenon: plug and socket can not be plugged together
Causes: plug and socket are not matched
Elimination methods: If you can not plug, can not be forced to force the plug, check the alignment of the jack position before plugging
Fourth, poor sealing.
Phenomenon: sealing was damaged
Causes: seal aging, failure
Remedy: replace the new seals
