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 method of elimination, today Huicheng Yuan connector factory for the user to summarize the use of a commonly encountered faults and elimination methods. Generally 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, the phenomenon: the contact resistance becomes large cause: Circular connector jack has been slack, positive pressure becomes small or deformation of the elastic parts Rule out the method: replace the new contact 2, the phenomenon: the contact does not have a good contact leading to disconnection cause: in the use of the use of incorrectly lead to changes in the diameter of the jack Rule out the method: replacement of the new jack 3, Phenomenon: contact curtain movement causes: contact size error is too large or jaw damage exclusion method: directly replace the circular connector or can also replace the contact 4, phenomenon: wire damage, breakage caused by the circuit breaker causes: in the wrapping of the wiring harness, the wire is not uniform force, the wiring port is not welded firmly, the installation error exclusion method: the use of the correct installation method, the contact re-welded two Insulation bad. 1, phenomenon: short circuit, insulation resistance is too poor cause: the environment used in the moisture or impurities to rule out the method: choose a dry, clean environment, clean off the impurities 2, phenomenon: insulator broken cause: in the insertion and extraction of too much force, defective insulators to rule out the method: replacement of the new circular connectors or insulators, three, poor fixation. 1, phenomenon: shell damage Causes: processing internal defects or damage by external forces Rule out the method: re-replace the qualified replacement connector 2, phenomenon: plug and socket can not be plugged in cause: plug and socket did not match Rule out the method: if you can not be plugged in, can not force to be forced to plug in, check the alignment of the jack position before plugging in. four, sealing is bad. Phenomenon: sealing was damaged to produce the reason: seal aging, failure to rule out the method: replace the new seals
